I'm no soul, man: a response to Baltimore

Joseph Baltimore argues that the account of postmortem survival I offered five years ago fails, based on the plausible assertion that identity is a relation that each thing necessarily stands in to itself. I believe that Baltimore is mistaken when he claims that the account I offer violates the necessity of identity, and also mistaken when he asserts that the account I offer cannot satisfy Noonan's ‘only x and y principle’.
Particle migration in shear fields

The motion of a single rigid sphere entrained in a glycerine-water solution flowing downward through a cylindrical tube has been investigated throughout a range of particle Reynolds numbers of 6.0 to 120.0, tube Reynolds numbers of 208 to 890, and particle-to-tube diameter ratios of 0.120 to 0.190. Trajectories of the sphere, calculated for various particle Reynolds numbers by using the Rubinow-Keller expression for the transverse force, were found to agree satisfactorily with experimentally determined trajectories when the particle Reynolds number was below 40.0. In all cases the sphere was observed to migrate to the axis of the tube. At the lower particle Reynolds numbers the sphere approached the axis asymptotically, whereas at the higher particle Reynolds numbers the sphere oscillated across the axis of the tube one or more times during migration. All observations were made with spheres which were less dense than the fluid, the density difference being as high as 10% of the fluid density.
Politics and Celebrity: A Sociological Understanding

Many social commentators have denounced the election of entertainment celebrities such as Arnold Schwarzenegger, Jesse Venture, and Al Franken to political offices as indicative of American democracy’s collapse, treating the political victories by these celebrities as evidence of America’s preference for entertainment over political deliberation. This essay reviews the scholarly literature on celebrity and politics to provide a better understanding of this important topic. As the literature demonstrates, this conflation of celebrity and politics is not a recent phenomenon, as politicians have long employed dramaturgical elements to mobilize constituencies. Indeed, celebrities and politicians share many similarities. Both must construct public personalities appealing to their audiences and employ similar actors and strategies to help create these personalities. While some scholars working in this field agree with the concern that celebrity’s presence in politics inhibits serious political discourse, other scholars contend that the use of celebrity performances by politicians may actually attract a wider segment of society to meaningfully participate in politics. The essay concludes by suggesting that future works in this area should adopt a cultural sociology framework to empirically study the meaning of celebrity for different social groups in order to gain a stronger understanding of celebrity’s sociopolitical impact.
Extrapulmonary Causes of Respiratory Failure

The causes of respiratory failure can be divided into two main groups: extrapulmonary and pulmonary. Extrapulmonary causes of respiratory failure include conditions that exclusively or primarily ca...
Thin‐Film Thermocouples Based on the System In2O3–SnO2

Ceramic thermocouples are being developed to replace noble-metal thermocouples that are unable to withstand the harsh environments inside the hot sections of turbine engines used for power generation and propulsion. A number of alloys in the system indium oxide (In2O3):tin oxide (SnO2) were systematically investigated as thermocouples. Specifically, solid solutions containing up to 10 wt% SnO2 were initially tested relative to a platinum reference electrode and the resulting thermoelectric properties were measured. The results indicated that the thermoelectric response was dependent on the SnO2 content in the alloy. Seebeck coefficients ranged from 53 to 224 μV/°C at temperatures up to 1300°C, which are considerably larger than those generated from metal thermocouples. Bi-ceramic thermocouples based on selected solid solutions of indium tin oxide (ITO) exhibited high temperature stability and Seebeck coefficient on the order of 160 μV/°C. Postdeposition treatments had a significant effect on the stability of the ceramic thermocouples. High-temperature annealing improved the film uniformity, stability, and reproducibility of the ITO thin-film thermocouples. A bi-ceramic thermocouple consisting of In2O3 and In2O3:SnO2 (95:5 wt%) was the best-performing thermocouple of all compositions studied.
A Mitochondrial Complex I Defect Impairs Cold-Regulated Nuclear Gene Expression

To study low-temperature signaling in plants, we previously screened for cold stress response mutants using bioluminescent Arabidopsis plants that express the firefly luciferase reporter gene driven by the stress-responsive RD29A promoter. Here, we report on the characterization and cloning of one mutant, frostbite1 (fro1), which shows reduced luminescence induction by cold. fro1 plants display reduced cold induction of stress-responsive genes such as RD29A, KIN1, COR15A, and COR47. fro1 leaves have a reduced capacity for cold acclimation, appear water-soaked, leak electrolytes, and accumulate reactive oxygen species constitutively. FRO1 was isolated through positional cloning and found to encode a protein with high similarity to the 18-kD Fe-S subunit of complex I (NADH dehydrogenase, EC 1.6.5.3) in the mitochondrial electron transfer chain. Confocal imaging shows that the FRO1:green fluorescent protein fusion protein is localized in mitochondria. These results suggest that cold induction of nuclear gene expression is modulated by mitochondrial function.
The Role of Endoscopic Ultrasonography (EUS) and Endoscopic Retrograde Cholangiopancreatography (ERCP) in the Evaluation and Management of Ampullary Adenomas

The endoscopic evaluation and management of ampullary adenomas is an excellent example of the complimentary use of endoscopic ultrasonography (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) in interventional endoscopy. EUS has an important role in the staging of ampullary masses and in the evaluation of underlying malignancy. Various technical approaches to EUS imaging of the ampulla have been described and each offers specific information regarding the resectability of these lesions. Short of surgical resection, EUS appears to offer the most detailed information regarding the T stage of ampullary lesions. This important information can be used to determine the likelihood of successful endoscopic therapy. Endoscopic papillectomy techniques have evolved over the past two decades. The technical issues regarding endoscopic papillectomy are driven more by anecdotes than evidence. The technique of endoscopic papillectomy is described in detail with a review of current practice variations and supportive literature. The incidence of complications reported in the recent literature and the need for surveillance after successful resection of ampullary adenomas are discussed.
Maternity leave and women's mental health.

The Wisconsin Maternity Leave and Health Study addresses an important policy issue, parental leave, by investigating the work status, maternity leave, and mental health of 570 women. In the longitudinal design, the women, all of whom were living with a husband or partner, were interviewed during the fifth month of pregnancy, 1 month postpartum, and 4 months postpartum. At 4 months postpartum, full-time workers, part-time workers, and homemakers did not differ in depression or anger, but full-time workers showed elevated anxiety compared with the other two groups. In multiple regression analyses, length of leave interacted significantly with marital concerns when predicting depression; women who took a short leave (6 weeks or less) and were high on marital concerns had the highest depression scores. Short maternity leave can be conceptualized as a risk factor that, when combined with other risk factors such as marital concerns, places women at greater risk for depression.
Automated testing of refactoring engines

Refactorings are behavior-preserving program transformations that improve the design of a program. Refactoring engines are tools that automate the application of refactorings: first the user chooses a refactoring to apply, then the engine checks if the transformation is safe, and if so, transforms the program. Refactoring engines are a key component of modern IDEs, and programmers rely on them to perform refactorings. A bug in the refactoring engine can have severe consequences as it can erroneously change large bodies of source code.We present a technique for automated testing of refactoring engines. Test inputs for refactoring engines are programs. The core of our technique is a framework for iterative generation of structurally complex test inputs. We instantiate the framework to generate abstract syntax trees that represent Java programs. We also create several kinds of oracles to automatically check that the refactoring engine transformed the generated program correctly. We have applied our technique to testing Eclipse and NetBeans, two popular open-source IDEs for Java, and we have exposed 21 new bugs in Eclipse and 24 new bugs in NetBeans.
Vanadium oxides synthesized using the tetramethylammonium ion: an addendum

The structures of several new vanadium oxides prepared hydrothermally using the tetramethylammonium ion, including the first layered vanadium oxide containing an organic specie, were reported earlier. The preparative conditions under which these vanadium oxides were synthesized are reported here.
An adaptive per-survivor processing algorithm

We propose an adaptive and parameter-independent per-survivor processing algorithm to improve the receiver performance on time-varying channels. With a variable step size for a plurality of survivor paths, this new method eliminates the dependency of all the survivor paths and improves the convergence rate of channel estimation.
(μ-Piperazine-1,4-dicarbodithioato-κS,S':S'',S''')bis-[triphenyl-tin(IV)] dichloro-methane solvate.

The dinuclear centrosymmetric title compound, [Sn2(C6H5)6(C6H8N2S4)]·CH2Cl2, features a distorted cis-trigonal–bipyramidal coordination geometry for Sn based on a C3S2 donor set. The dinuclear mol­ecule lies across a centre of inversion. The solvent dichloro­methane mol­ecule is disordered about a centre of inversion.
Transmembrane Events in Mast Cell Histamine Release

Bridging of IgE-receptors on mast cells and basophil granulocytes induces an enhancement of phosphatidylinositol (PI) turnover and mobilization of intracellular Ca2+, followed by the activation of protein kinase C. Pretreatment of sensitized mouse bone marrow-derived mast cells (BMMC) with either pertussis toxin (PT) or cholera toxin (CT), which ADP-ribosylates GTP-binding protein Gi or Gs, affected neither the formation of inositol phosphates nor histamine release induced by the bridging of IgE-receptors. In contrast, the treatment of the cells with PT or CT either inhibited or enhanced histamine release induced by IgE-independent stimuli. It was also found that introduction of GTPγS or GTPβS into permeabilized BMMC did not affect the IgE-mediated histamine release. It appears that GTP-binding protein is not involved in the transduction of the triggering signals from IgE-receptors for histamine release.
Preliminary results of a phase I trial of sorafenib combined with cisplatin/etoposide (CE) or carboplatin/pemetrexed (CbP) in solid tumor patients (pts)

e13521 Background: Sorafenib had demonstrated single agent activity in non-small cell and small cell lung cancer. Methods: A non-comparative, two arm phase I trial escalating sorafenib in combination with fixed doses of CE or CbP was performed. A 3-patient cohort design was utilized to determine the maximum tolerated dose (MTD) and dose limiting toxicities (DLT). Dose level 0 for all pts was a sorafenib dose of 200 mg po BID continuously. Pts on arm A received C (60 mg/m2) on day 1 and E 120 mg/m2 on days 1,2,3 every 3 weeks with escalating doses of sorafenib. On arm B, pts received treatment with Cb (AUC=6) and P 500 mg/m2 every 3 weeks with escalating doses of sorafenib. However, excessive toxicity was observed on arm B, therefore the trial was amended such that Cb dose was lowered to AUC=5 (arm C). DLT were assessed in the 1st cycle and defined as grade (gr.) 4 anemia or thrombocytopenia, gr. 4 neutropenia lasting > 7 days, gr. ≥ 3 non-hematologic toxicity (except nausea, vomiting, and alopecia) and > ...
Facilitating Interactive Evaluation Practice: Engaging Stakeholders Constructively

This chapter introduces interactive evaluation practice (IEP) and its potential for grounding thinking about the foundational nature of interaction in evaluation studies and the role of facilitation in this process. It begins by defining key terms and elaborating specifically on IEP as an evaluator orientation for grounding and guiding decisions, actions, and reflections—all leveraged toward conducting meaningful studies. It then presents an evaluator's dozen of strategies useful for facilitating interaction among stakeholders to accomplish targeted aims and concludes by illustrating how evaluators can successfully facilitate these strategies in practice.
Removal of arsenic from water using manganese (III) oxide: Adsorption of As(III) and As(V)

Removal of arsenic from water was evaluated with manganese (III) oxide (Mn2O3) as adsorbent. Adsorption of As(III) and As(V) onto Mn2O3 was favorable according to the Langmuir and Freundlich adsorption equilibrium equations, while chemisorption of arsenic occurred according to the Dubinin-Radushkevich equation. Adsorption parameters from the Langmuir, Freundlich, and Temkin equations showed a greater adsorption and removal of As(III) than As(V) by Mn2O3. Maximum removal of As(III) and As(V) occurred at pH 3-9 and at pH 2, respectively, while removal of As(V) in the pH range of 6-9 was 93% (pH 6) to 61% (pH 9) of the maximum removal. Zeta potential measurements for Mn2O3 in As(III) was likely converted to As(V) solutions indicated that As(III) was likely converted to As(V) on the Mn2O3 surface at pH 3-9. Overall, the effective Mn2O3 sorbent rapidly removed As(III) and As(V) from water in the pH range of 6-9 for natural waters.
Theoretical prediction of the structures and energies of olympicene and its isomers.

Pentacene, a linear five-ringed polyaromatic hydrocarbon, has recently been used as an organic semiconductor in field-effect transistors. The recently synthesized olympicene molecule, so named because of its resemblance to the olympic rings, is a more compact five-ringed structure. This paper offers the first theoretical study of the kinetic stability of olympicene and its isomers. We use the parametric two-electron reduced density matrix (2-RDM) method, which takes the 2-RDM as the basic variable in lieu of the traditional wave function in calculations [Mazziotti, D. A. Phys. Rev. Lett. 2008, 101, 253002]. Our calculations demonstrate that olympicene’s isomers may be separated into aromatic and diradical isomers, the latter of which require accurate treatment of strong electron correlation to detect multireference character. Albeit formally a single-reference method, the parametric 2-RDM captures the multireference correlation of the diradical isomers; relative to olympicene, the 2-RDM predicts five dira...
Effects of Various Anesthetic Agents on the Blood Pressure of the White Rat.

SummaryThe method of Byrom and Wilson as modified! for this study is well adapted for the determination of blood pressure in the rat. The mean arterial systolic pressure in the unanesthetized animal was found to be 124.8 mm Hg. The mean pressures obtained by the use of anesthetic agents were as follows: nembutal—104.1, amytal—103.5, ether (shallow)—117, ether (deep)—104, urethane—78.4, morphine—63.9 mm Hg,
Predicted Liquid Atomization from a Spent Nuclear Fuel Reprocessing Pressurization Event.

Spent nuclear fuel reprocessing may involve some hazardous liquids that may explode under accident conditions. Explosive accidents may result in energetic dispersion of the liquid. The atomized liquid represents a major hazard of this class of event. The magnitude of the aerosol source term is difficult to predict, and historically has been estimated from correlations based on marginally relevant data. A technique employing a coupled finite element structural dynamics and control volume computational fluid dynamics has been demonstrated previously for a similar class of problems. The technique was subsequently evaluated for detonation events. Key to the calculations is the use of a Taylor Analogy Break-up (TAB) based model for predicting the aerodynamic break-up of the liquid drops in the air environment, and a dimensionless parameter for defining the chronology of the mass and momentum coupling. This paper presents results of liquid aerosolization from an explosive event.

EFFECTS OF FRACTURE DAMAGE ON WELL PRODUCTIVITY

In the fracture well of the casing perforation, the fracture was damaged, that is the choked fracture and fluid leak - off damage. An analyzable method was introduced to study the effects of fracture damages on fractured well productivity. The results indicated both can greatly decrease productivity index while choked fracture had more side effects on well productivity. Some measurements must be taken to minish choked fracture and decrease fracture fluid leak off.
Understanding “Ostalgie” and Social Connectedness in the Former German Democratic Republic: A Consumer Perspective

In 1989, the former East Germany (or GDR) went through dramatic political, economic, and social changes with influence to the consumer. Despite the GDR’s complex transfer nearly 20 years ago, it provides a rare opportunity to explore how new consumption patterns affect people’s social relationships. One useful construct for studying consumers’ social relationships is social connectedness, which is the subjective awareness of interpersonal closeness with the social world (Lee and Robbins, 1998). The social world includes proximal and distal relationships with family, friends, peers, acquaintances, strangers, community, and society as a whole (Lee and Robbins 1995, 1998, 2000). Consumers' feelings of social connectedness are quite powerful and can be used to measure one of the most fundamental higher order needs-the need of belonging (Baumeister and Leary 1995; Kohut 1984, Lee and Robbins 1995, 2000, Maslow 1970). Published consumer research studies on transitional societies have focused on consumer relationships with brands rather than on the social implications of changing consumption patterns (Coulter et al. 2003; Feick et al. 1995). Additional research has examined consumers’ connectedness within the realms of brand communities where brands take center stage for personal interaction (e.g. Algesheimer et al. 2005; Belk and Tumbat 2005; Kozinets 1999; Muniz and Schau 2005; Schouten and McAlexander 1995). While brand communities manifest the degree of connectedness between the consumer and the brand (Ouwersloot and Odekerken-Schroder 2008), this research recognizes that the construct of social connectedness exists independent of brands, and views social connectedness as a psychological construct that recognizes the fact that community is only one aspect of the social world (family, friends, acquaintances, strangers, and society also comprise the social world).
Unfoldomics of prostate cancer: on the abundance and roles of intrinsically disordered proteins in prostate cancer

Prostatic diseases such as prostate cancer and benign prostatic hyperplasia are highly prevalent among men. The number of studies focused on the abundance and roles of intrinsically disordered proteins in prostate cancer is rather limited. The goal of this study is to analyze the prevalence and degree of disorder in proteins that were previously associated with the prostate cancer pathogenesis and to compare these proteins to the entire human proteome. The analysis of these datasets provides means for drawing conclusions on the roles of disordered proteins in this common male disease. We also hope that the results of our analysis can potentially lead to future experimental studies of these proteins to find novel pathways associated with this disease.
COMBINATORIAL THEOREMS FOR THE CONSTRUCTION OF MODELS

Publisher Summary This chapter discusses combinatorial theorems for the construction of models. It provides a further study of the interconnections between model theory and combinatorics and attempt a systematic development. Since the compactness of first-order logic is one of the most successfully used properties in model theory, it is natural to investigate the role of compactness also in our more general framework. This leads to a program of finding simple combinatorial analogues of the main results of first-order model theory. Clearly, it is to be expected that some such results, because of their more general character, will become of independent interest.
“Innocent Objects:” Fetishism and Melancholia in Orhan Pamuk’s The Museum of Innocence

In this article, I place Orhan Pamuk’s novel The Museum of Innocence into dialogue with Sigmund Freud’s theory of the fetish. As Gerhard Neumann argues, the fetish provides the basic pattern for the modern subject and its experience of self and the world while performing the impossibility of narrating this experience. In a similar vein, the fetishized objects described in the novel and put on display in Pamuk’s actual museum in Istanbul complicate the narrator’s account of a lost love relationship. The fetish objects create an intertwinement of coalescing and contradicting narratives that point to “black melancholia” as a deeply ambiguous feeling in the collective memory of Istanbul and its people.
A Loss of Profilin‐1 in Late Stage Oral Squamous Cell Carcinoma

Background The genes for PFN1 and TMSB4 are both highly expressed in oral tissue and both encode actin monomer binding proteins thought to play a role in cell motility and possibly other crucial parts of tumor progression. Methods Oral brush cytology of epithelium from oral squamous cell carcinoma (OSCC) was used to measure PFN1 and TMSB4 mRNA in OSCC, while immunohistochemical analysis of tissue was used to check protein levels. Results High but variable expression of mRNAs encoding these two proteins was observed suggesting they may contribute to tumor characteristics in a subset of OSCCs. Both proteins were highly expressed in normal appearing basal epithelium, in the cytoplasm, and perinuclear area, while expression was minimal in upper epithelial layers. In OSCCs, expression of these proteins varied. In tumors classified as later stage, based on size and/or lymph node involvement, PFN1 levels were lower in tumor epithelium. A control gene, KRT13, showed expression in normal differentiated basal and suprabasal oral mucosa epithelial cells and as reported was lost in OSCC cells. Conclusion Loss of PFN1 in tumor cells has been associated with lymph node invasion and metastasis in other tumor types, strengthening the argument that the protein has the potential to be a tumor suppressor in late-stage OSCC.
A microstructural study of the degradation and calcium release from hydroxyapatite-calcium oxide ceramics made by infiltration.

Abstract Hydroxyapatite pellets, partially densified in a low-temperature heat treatment, were infiltrated with calcium nitrate solution followed by in-situ precipitation of Ca(OH)2 and CaCO3. The infiltrated bodies were then densified to high relative density and the calcium carbonate transformed to calcium oxide during sintering and resulted in biphasic hydroxyapatite-CaO ceramics. This work investigated the influence of the infiltration on surface morphology, weight change, and microstructural-level degradation caused by exposure to saline at pH = 7.4 and a temperature of 20 °C. The CaO rendered the materials more susceptible to degradation, and released calcium into the saline faster than single phase, calcium deficient hydroxyapatite (HA) that were used as a control. In consequence, these ceramics could be used to release calcium into the culture microenvironments of bone tissue or bone marrow cells next to a scaffold surface.
View From the American Society of Reconstructive Transplantation

The transplant community as represented by the diverse readership of the American Journal of Transplantation (AJT) may be interested in recent advances in the field of vascularized composite allotransplantation (VCA) occurring determinedly in the US and worldwide, and become enticed to contribute actively to the advancement of this innovative field. Although the first hand transplant was performed in the US in 1999, only recently has there been more widespread professional and public awareness of this new indication for transplantation to optimally restore form and function and replace like-with-like tissue in cases where conventional reconstruction is not feasible. While upper extremity and face are the most common VCA procedures, abdominal wall, genitourinary and lower extremity transplants are also occurring (1, 2). This article is protected by copyright.

Efficient Classification of Long Time Series by 3-D Dynamic Time Warping

Throughout recent years, dynamic time warping (DTW) has remained as a robust similarity measure in time series classification (TSC). 1-nearest neighbor (1-NN) algorithm with DTW is the most widely used classification method on time series serving as a benchmark. With the increasing demand for TSC on low-resource devices and the widespread of wearable devices, the need for a efficient and accurate time series classifier has never been higher. Although 1-NN DTW attains accurate results, it highly falls back on efficiency due to its quadratic complexity in the length of time series. In this paper, we propose a new approximation method for reducing the length of the time series as the input of DTW. We call it control chart approximation (CCA), after a similar concept used in statistical quality control processing. CCA representation approximates raw time series by transforming them into a set of segments with aggregated values and durations forming a reduced 3-D vector. We also propose an adaptation of DTW in 3-D space as a distance measure for 1-NN classifier, and denote the method as 1-NN 3-D DTW. Our experiments on 85 datasets from UCR archive—including 28 long-length (>500 points) time series datasets—show up to two orders of magnitude performance gain in running time compared to the state-of-the-art 1-NN DTW implementation. Moreover, it shows similar or better accuracy on the long time series in the experiment.
Intraoperative Raman Spectroscopy

Surgical excision of brain tumors provides a means of cytoreduction and diagnosis while minimizing neurologic deficit and improving overall survival. Despite advances in functional and three-dimensional stereotactic navigation and intraoperative MRI, delineating tissue in real time with physiologic confirmation is challenging. Raman spectroscopy has potential to be an important modality in the intraoperative evaluation of tissue during surgical resection. In vitro experimental studies have shown that this technique can be used to differentiate normal brain tissue from tissue with infiltrating cancer cells and dense cancerous masses with high specificity, indicating the feasibility of this method for in vivo application.
Diving into the Wreck: BP and Kenneth Feinberg’s Gulf Coast Gambit

The 1990 Oil Pollution Act mandate - that a party “responsible” for an oil spill establish a “procedure” to pay interim damages - has largely removed the courts from the process of determining scope of liability and turned it over to the private ordering of the claims bureau established by the responsible parties designated by the President under the OPA.BP put its “procedure” in the hands of a lawyer of solomonic reputation - Kenneth Feinberg. His broad settlement authority was designed to produce both prompt compensation for current losses (without prejudice to future claims) and early settlements of claims for any future losses. Through its Gulf Coast Claims Facility BP - making interim payments - has had a nearly free hand in determining the extent of its liability under the OPA. Though plaintiffs lawyers have moved to “supervise” the process through the MDL, neither a negotiated grid nor any court ruling has defined the scope of liability.BP’s private claims resolution process is almost entirely unregulated. Only after months of jaw-boning by Gulf Coast Attorneys General and the U.S. Attorney General did BP agree to be audited. No regulations govern responsible parties who establish a “procedure”. The GCCF’s allocations are often impenetrable. BP’s GCCF can be described as the pseudo-fund model for mass tort claims resolution. Though its name suggests an independent fund, the GCCF is in fact merely BP’s statutorily compelled mechanism for satisfying economic loss and clean-up claims. In the absence of either regulatory guidance or court rulings on scope of liability the settlement parameters are indistinct to claimants. Even BP is uneasy because Feinberg’s settlement offers under the OPA go well beyond the narrow parameters of maritime courts which in spill claims have historically denied compensation to all in the supply chain except fishermen and those who suffered property damage. The executive branch should examine the OPA’s regulatory gap. No regulations govern the manner in which a solvent polluter meets its statutory clean-up and compensation responsibilities. There is no liability guidance, no audit, no reporting, no monitoring of the company’s ability to meet its obligations, no review of its success in meeting its obligations. If the executive branch does not take this up, Congress in its oversight capacity should do so.
High-resolution magnetostratigraphy of the Upper Nacimiento Formation, San Juan Basin, New Mexico, USA: Implications for basin evolution and mammalian turnover

Lower Paleocene deposits in the San Juan Basin document one of the best records of mammalian change and turnover following the Cretaceous-Paleogene mass extinction and is the type area for the Puercan (Pu) and Torrejonian (To) North America Land Mammal age (NALMA). One of the largest mammalian turnover events in the early Paleocene occurs between the Torrejonian 2 (To2) and Torrejonian 3 (To3) NALMA interval zones. The Nacimiento Formation contains the only deposits in North America where the To2-To3 mammalian turnover can be constrained; however, the precise age and duration of the turnover is poorly understood due to the lack of a precise chronostratigraphic framework. We analyzed paleomagnetic samples, produced a 40Ar/39Ar detrital sanidine age, and developed a detailed lithostratigraphy for four sections of the upper Nacimiento Formation in the San Juan Basin, New Mexico (Kutz Canyon, Escavada Wash, Torreon West and East) to constrain the age and duration of the deposits and the To2-To3 turnover. The polarity stratigraphy for the four sections can be correlated to chrons C27r-C26r of the geomagnetic polarity time scale (GPTS). Using the local polarity stratigraphy for each section, we calculated a mean sediment accumulation rate and developed a precise age model, which allows us to determine the age of important late Torrejonian mammalian localities. Using the assigned ages, we estimate the To2-To3 turnover was relatively rapid and occurred over ∼120 kyr (−60/+50 kyr) between 62.59 and 62.47 Ma. This rapid duration of mammalian turnover suggests that it was driven by external forcing factors, such as environmental change driven by the progradation of the distributive fluvial system across the basin and/or changes in regional or global climate. Additionally, comparisons of the mean sediment accumulation rates among the sections that span from the basin margin to the basin center indicate that sediment accumulation rates equalized across the basin from the end of C27r through the start of C26r, suggesting an accommodation minimum in the basin associated with the progradation of a distributive fluvial system into the basin. This accommodation minimum also likely led to the long hiatus of deposition between the Paleocene Nacimiento Formation and the overlying Eocene San Jose Formation.
The Effects of a Roommate-Pairing Program on International Student Satisfaction and Academic Success

While great attention has been given to the growth of international students at U.S. institutions, there is a gap in the literature examining support for this student population within residence halls. To address the gap, this quantitative study evaluated an international roommate-pairing program (IRP) by comparing the residential experience of IRP participants with a control group. The results showed the roommate-pairing program had a positive impact on the residential experience of international students. These findings suggest physical environment and structured support are critical factors in the satisfaction and success of international students. This research can inform the practice of Residence Life professionals and aid in the establishment of effective support programs.
Edaphic Restriction of Cupressus Forbesii (Tecate Cypress) in Southern California, U.S.A.--A Hypothesis

The restriction of some terrestrial plant species to unusual or extreme substrates such as soils derived from ultramafic rocks has long fascinated ecologists (Proctor, Woodell, 1975). Sharply restricted plant distributions exemplify one of the most general ecological problems: What limits the local and regional abundance of species? There is reason to hope that deepening our knowledge of the causes of the dramatic distributions of rare plants will help us to understand the more subtle patterns of common species.
Community engaged research projects for undergraduates

A commitment to providing research opportunities for undergraduates has been a key element in Harvey Mudd's efforts to increase the diversity of our computer science student body [1]. Including students in problems outside of the classroom helps them develop identities as computer scientists, while providing those opportunities early on in students' careers, can help welcome new students to the field [14]. But many first-year undergraduate students don't have a lot of previous experience, so it can be difficult to find research positions where they can make substantial technical contributions. Student-driven, community-engaged data analysis projects offer an opportunity to engage those students.
E-007 A1 segment patency outcomes following pipeline embolization device deployment from the distal internal carotid artery into the M1 segment

Introduction Utilization of the Pipeline Embolization Device (PED) for treating large and giant aneurysms of the distal internal carotid artery (ICA) is not well characterized. Conclusive evidence does not exist regarding flow diversion consequences related to PED placement into the M1 segment of the middle cerebral artery (MCA). Methods A retrospective chart review of patients treated for aneurysms with PEDs that extend into the MCA. All treated at a single medical center between 2011 and the present. Patient demographics, follow-up imaging and bilateral A1 and M1 vessel diameters with pertinent ratios were recorded. Results A total of 32 patients were included in the study (9 male, 23 female, ages 51±14 years). Follow-up angiogram was conducted at an average of 6±2 months. Seventeen (53%) patients demonstrated complete patency of the covered A1 segment and 3 (9%) patients showed narrowing of this segment. Twelve (38%) patients demonstrated occlusion of the covered A1 segment. Together, patients who maintained A1 patency and those that only showed vessel narrowing had an average A1 diameter to ipsilateral M1 segment diameter ratio of 0.70 and an average A1 diameter to contralateral A1 diameter ratio of 1.09. These values corresponded to 1.30 and 1.51 times their equivalent ratios in the patients whose A1 did not demonstrate blood flow on follow-up angiogram. Interestingly, none of the patients treated developed anterior cerebral artery (ACA) stroke or worsening of modified Rankin Score on follow-up. Two patients experienced vision loss and one patient’s stent was found to be asymptomatically occluded. Conclusions The PED can safely be used to treat aneurysms with deployment from the distal ICA into the M1 segment of MCA. Unilateral A1 segment dominance may be predictive of cerebral blood flow into the ACA following deployment at this location. Learning objectives Identify opportunities for safe application of the Pipeline Embolization Device (PED) with coverage of the ACA. Discuss flow–related dynamics of the ICA–terminus and how they relate to PED placement and vessel dominance. Disclosures A. Pujari: None. B. Howard: None. T. Madaelil: None. C. Cawley: None. J. Grossberg: None.
From conceptual to computational: Cost and benefits of lizard thermoregulation revisited.

Abstract A classic paper detailed conceptual analyses of behavioral thermoregulation (Huey and Slatkin, 1976) and has served as the theoretical foundation for hundreds of investigative studies. Most recently, investigators have revisited this theoretical presentation to offer additional interpretation for both heterogeneity and spatial structure of temperature and how it may influence energetic costs (Sears and Angilletta, 2015). Interestingly, this foundational presentation by Huey and Slatkin, over 40 years ago, has never received formal computational analyses to address mathematically the postulates of this conceptual model. Here we use functions that closely mimic those that were described by Huey and Slatkin to provide both a theoretical and computational analysis for the cost and benefits of lizard thermoregulation. We demonstrate both the utility and inherent accuracy of their analyses using a model that was developed conceptually without the use of now readily available computational tools. But contrary to Huey and Slatkin's analyses, we provide a mathematical proof that perfect thermoregulation is never an optimal strategy and show by computational analysis that thermoregulatory strategy (k ) may decrease, not increase, with increasing cost.
Novel compositions and physical property comparisons for (A , A ′) 2.5 VMoO8 lyonsites (A=Zn, A ′ =Mn, Ni, Cu)

Abstract This work details a comparative investigation within the system Zn 2.5 − x A ′ x VMoO 8 ( A ′ 2 + = Mn, Ni, Cu). Samples were prepared between 700 and 1000 °C, resulting in various colors. All three solid solutions were found to exhibit a miscibility gap before or at the midpoint, beyond which phase separation occurs. X-ray and neutron powder diffraction were used to elucidate the cause of these solubility limits and diffuse reflectance measurements revealed varying color mechanisms. All phase pure members of the solid solutions are found to be similar to the parent compound, and magnetic susceptibility measurements confirmed the +2 oxidation state for all substitutions, with tendency towards antiferromagnetic exchange as x increases.
Predicting plug loads with occupant count data through a deep learning approach

Abstract Predictive control has gained increasing attention for its ability to reduce energy consumption and improve occupant comfort in buildings. The plug loads prediction is a key component for the predictive building controls, as plug loads is a major source of internal heat gains in buildings. This study proposed a novel method to apply the Long-Short-Term-Memory (LSTM) Network, a special form of Recurrent Neural Network, to predict plug loads. The occupant count and the time have been confirmed to drive the plug load profile and thus selected as the features for the plug load prediction. The LSTM network was trained and tested with ground truth occupant count data collected from a real office building in Berkeley, California. Results from the LSTM network markedly improve the prediction accuracy compared with traditional linear regression methods and the classical Artificial Neural Network. 95% of 1-h predictions from LSTM network are within ±1 kW of the actual plug loads, given the average plug loads during the office hour is 8.6 kW. The CV(RMSE) of the predicted plug load is 11% for the next hour, and 20% for the next 8 h. Lastly, we compared four prediction approaches with the office building we monitored: LSTM vs. ARIMA, with occupant counts vs. without occupant counts. It was found, the prediction error of the LSTM approach is around 4% less than the ARIMA approach. Using occupant counts as an exogenous input could further reduce the prediction error by 5%–6%. The findings of this paper could shed light on the plug load prediction for building control optimizations such as model-predictive control.
Performance Analysis of the NWChem TCE for Different Communication Patterns

One-sided communication is a model that separates communication from synchronization, and has been in practice for over two decades in libraries such as SHMEM and Global Arrays (GA). GA is used in a number of application codes, especially NWChem, and provides a superset of SHMEM functionality that includes remote accumulate, among other features. Remote accumulate is an active-message operation that applies \(y+=a*x\) at the target rather than just \(y=x\) (as in Put) which gives the programmer additional choices with respect to algorithm design. In this paper, we discuss and evaluate communication scenarios for dense block-tensor contractions, one of the mainstays of the NWChem computation chemistry package. We show that apart from the classical approach involving dynamic scheduling of data blocks for load balancing, reordering one-sided Get and Accumulate calls affects the performance of tensor contractions on leadership-class machines substantially. In order to understand why this reordering affects the performance, we develop a proxy application for the NWChem Tensor Contraction Engine (TCE) module. We utilize this proxy application to compare different implementations with a focus on communication.
Evaluation of Stimulatory, Antifungal and Thermo-Resistant Action of Aqueous Dispersions of Nanoparticles on Seeds of Parental Forms and Reciprocal Hybrids of Winter Wheat

For the first time in the crop technology, the effect of aqueous dispersions of nanoparticles was investigated on seeds of parental forms and their reciprocal hybrids, making it possible to effectively use this factor in plant breeding and genetic practice. The received data can be used to select optimal pairs for crossing and obtain new promising hybrids. It was shown the stimulatory, antifungal and thermo-resistant action (increase of resistance to pathogenic fungus) of water dispersed solutions of silver and copper nano-particles on seeds of winter triticale. The antifungal effect of the nanofactor is more effective than of the potassium permanganate. In terms of seed germination energy and sprout length of winter wheat (parent varieties and their reciprocal hybrids) we revealed the stimulatory and antifungal action of aqueous dispersions of silver, copper, bismuth, and zinc oxide nanoparticles on the seeds. The maternal effect is revealed—the primary influence of the maternal form on the physiological parameters of the hybrid.
Group Search Strategy

In this paper, we consider the fixed-sample and sequential strategies in group search, and we break the conventional wisdom that the sequential search strategy always dominates the fixed-sample strategy. We model group search as a game among group members, and we show that the fixed-sample strategy is preferable to the sequential strategy when the unit search cost (relative to the dispersion of the product value distribution) is very low or high enough. The sequential strategy has the information advantage compared to the fixed-sample strategy because decision makers can make use of information gained during the search process. However, due to the divergence of preferences in group search, the information advantage of the sequential strategy is reduced, whereas the commitment advantage of the fixed-sample strategy emerges: when the unit search cost is large, the fixed-sample strategy commits to a smaller number to search to save search cost, whereas when the unit search cost is small, the fixed-sample strategy chooses a larger number to search than the sequential strategy because it allows group members to commit to a number to search and prevents over-search upfront. Further, we show that our result is robust to a change in the distribution assumption or in the size of the group.
Subway: minimizing data transfer during out-of-GPU-memory graph processing

In many graph-based applications, the graphs tend to grow, imposing a great challenge for GPU-based graph processing. When the graph size exceeds the device memory capacity (i.e., GPU memory oversubscription), the performance of graph processing often degrades dramatically, due to the sheer amount of data transfer between CPU and GPU. To reduce the volume of data transfer, existing approaches track the activeness of graph partitions and only load the ones that need to be processed. In fact, the recent advances of unified memory implements this optimization implicitly by loading memory pages on demand. However, either way, the benefits are limited by the coarse-granularity activeness tracking - each loaded partition or memory page may still carry a large ratio of inactive edges. In this work, we present, to the best of our knowledge, the first solution that only loads active edges of the graph to the GPU memory. To achieve this, we design a fast subgraph generation algorithm with a simple yet efficient subgraph representation and a GPU-accelerated implementation. They allow the subgraph generation to be applied in almost every iteration of the vertex-centric graph processing. Furthermore, we bring asynchrony to the subgraph processing, delaying the synchronization between a subgraph in the GPU memory and the rest of the graph in the CPU memory. This can safely reduce the needs of generating and loading subgraphs for many common graph algorithms. Our prototyped system, Subway (subgraph processing with asynchrony) yields over 4X speedup on average comparing with existing out-of-GPU-memory solutions and the unified memory-based approach, based on an evaluation with six common graph algorithms.
Stressful life events and adolescent suicidality: An investigation of the mediating mechanisms.

Abstract Introduction While a number of studies have found an association between stressful life events and adolescent suicidality, underlying mechanisms linking the two continue to be inadequately understood. Drawing upon the stress process, general strain, and support deterioration theories, this study examined the relationship between stressful life events and suicidality in U.S. adolescents, focusing on the mediating roles of depression, substance use, and perceived social support. Methods The data came from the first two waves of the National Longitudinal Study of Adolescent to Adult Health (N = 12,801; M age = 15 at Wave I; 50.2% female). Mediation analyses were performed using the Karlson-Holm-Breen (KHB) method developed for nonlinear probability models. Results Depression, substance use, and perceived social support accounted for a substantial part of the effect of stressful life events on suicidal ideation (57%) and attempts (43%). All mediating effects were statistically significant. Depression was a relatively stronger mediator for both suicidal outcomes. Significant relationships among stressful life events and suicidal outcomes persisted even after adjusting for the proposed mediators. Conclusion Stressful life events increase suicidality in adolescents, partly by increasing psychological distress and eroding perceived social support. Findings underscore the necessity of continued emphasis on stress management and support programs in reducing suicidality among vulnerable adolescents exposed to these types of occurrences.
