Eros Effect as Emergency Politics: Affective and Networked Politics of Agonistic Humanism in South Korea’s Sewol Ferry Disaster

AbstractThis article examines how people, based on their personal reception of a crisis, come together and organize themselves to readdress the status quo in a state of emergency by exploring the sociopolitical power of affect, empathy, and spontaneity as a transformative movement mobilizer. Using Bonnie Honig’s notion of Emergency Politics, this article further conceptualizes George Katsiaficas’ notion of Eros Effect by reconsidering the transformative, constitutive power of people’s plural and contingent political agency in a crisis situation. Human affect, especially empathy to the devastated, coupled with communication networks, helps consolidate and spread what Herbert Marcuse called the New Sensibility of the human species as a transformative political power. This article further complicates Bonnie Honig’s claim on agonistic humanism by revisiting a dichotomy of mourning mothers and acting fathers. As an empirical case, this article investigates how the Korean people have organized themselves in a s...

Crystal structure of dimethyl 3,4,5,6-tetra-phenyl-cyclo-hexa-3,5-diene-1,2-di-carboxyl-ate.

In the title compound, C34H28O4, the cyclo­hexa­diene ring has a screw-boat conformation with a torsion angle between the double bonds being on average ca 15° [15.2 (3) and −15.3 (3) in the two independent mol­ecules]. All four phenyl rings in both mol­ecules are arranged in a propeller-like conformation. The two mol­ecules exhibit S,R- and R,S- chirality, respectively, and are connected via C—H⋯O inter­molecular inter­actions. In turn, these weakly bound dimers form the mol­ecular crystal.
Wafer-Level Packaging Using Localized Mass Deposition

This paper describes a new wafer-level packaging technique in which the vacuum cavity is created using silicon-glass bonding and is subsequently sealed using localized polysilicon CVD. This allows cavity evacuation after bonding and sealing with the chip near ambient temperature. The cavity pressure is measured by monitoring the quality factor (Q) of an embedded comb resonator and can be adjusted as needed using an active getter. Measured Qs of ∼2300 indicate that cavity pressures below 50mTorr have been achieved.
Programming Streaming FPGA Applications Using Block Diagrams in Simulink

Publisher Summary This chapter describes a high-performance image-processing system by using Simulink and mapping to a field programmable gate array (FPGA)-based platform using a design flow built around the Xilinx system generator tools. The system implements edge detection in real time on a digitized video stream and produces a corresponding video stream labeling the edges. The edges can then be viewed on a high-resolution monitor. This design demonstrates how to describe a high-performance parallel datapath, implement control subsystems, and interface to external devices, including embedded processors. The Simulink approach allows the description of highly concurrent systems where many operators—perhaps the entire dataflow path—can operate simultaneously. The capability of Simulink as a common design framework for both algorithm and architecture development, with an automated path to program FPGA platforms combined with a rich library of high-performance parameterized stream-based DSP components, allows new applications to be developed and tested quickly. The real-time Sobel video edge detection runs on the BEE2 platform, which has a dedicated LCD monitor connected to it. The goal of the edge detection design driver is to generate a binary bit mask from a video source operating at up to a 200 MHz pixel rate, identifying where likely edges are in an image.

Physiologically grounded metrics of model skill: a case study estimating heat stress in intertidal populations

Models of ecological responses to climate change fundamentally assume that predictor variables, which are often measured at large scales, are to some degree diagnostic of the smaller-scale biological processes that ultimately drive patterns of abundance and distribution. Given that organisms respond physiologically to stressors, such as temperature, in highly non-linear ways, small modelling errors in predictor variables can potentially result in failures to predict mortality or severe stress, especially if an organism exists near its physiological limits. As a result, a central challenge facing ecologists, particularly those attempting to forecast future responses to environmental change, is how to develop metrics of forecast model skill (the ability of a model to predict defined events) that are biologically meaningful and reflective of underlying processes. We quantified the skill of four simple models of body temperature (a primary determinant of physiological stress) of an intertidal mussel, Mytilus californianus, using common metrics of model performance, such as root mean square error, as well as forecast verification skill scores developed by the meteorological community. We used a physiologically grounded framework to assess each model's ability to predict optimal, sub-optimal, sub-lethal and lethal physiological responses. Models diverged in their ability to predict different levels of physiological stress when evaluated using skill scores, even though common metrics, such as root mean square error, indicated similar accuracy overall. Results from this study emphasize the importance of grounding assessments of model skill in the context of an organism's physiology and, especially, of considering the implications of false-positive and false-negative errors when forecasting the ecological effects of environmental change.
The Management of Salivary Neoplasms an Overview

From 1939 through 1973, 2,807 patients with salivary gland tumors received definitive treatment at the Memorial Sloan Kettering Cancer Center. This included 1,965 patients (70%) with parotid gland lesions, 244 patients (8%) with neoplasms in the submandibular gland, and 607 patients (22%) with tumors which arose in the predominantly mucus secreting glands (minor salivary) which line the upper aerodigestive tract. The proportion with malignant tumors was 25, 43, and 82% in the parotid, submandibular and minor salivary glands, respectively; benign tumors occurred more often in women. Mucoepidermoid, acinic cell and most adenocarcinomas were subdivided according to histologic grade and all patients were retrospectively staged according to criteria established by the American Joint Committee on Cancer Staging. Treatment was almost exclusively surgical and the extent of the operation performed depended on the extent of the tumor rather than its histology. In patients with malignant parotid tumors, the facial nerve was sacrificed only if it was adherent to or directly involved by the tumor. Lymphadenectomy was usually reserved for those patients who had palpable metastases. Prolonged follow-up (10 years minimum in this study) is necessary in order to appreciate the slow growth of some salivary neoplasms. Results depended upon the complex interplay between the site of origin, the clinical stage, and the histologic appearance of the tumors. This study antedates our current interest in postoperative radiation therapy, but other reports suggest that combination therapy enhances local control.
Motivating a market or regulatory solution to IoT insecurity with the Mirai botnet code

Botnets compromised of IoT devices have been on the rise recently with attacks originating from compromised refrigerators, DVRs, security cameras, and other consumer networking equipment. Most owners of these devices are neither security aware or motivated to secure their IoT devices. Manufacturers of these devices are not currently motivated by market forces or regulatory requirements to improve the security of their products. At 7:00 a.m. on October 21st of 2016 the Mirai IoT botnet launched a DDoS attack against Dyn, a major DNS provider. The attacking hosts generated 1.2 terabits of malicious traffic forcing Dyn off the Internet for hours. This was the second high profile attack by the Mirai botnet. Noted security blogger Brian Krebs' site was the target of the first high profile Mirai attack on September 20, 2016. As a result of the publicity the source code for the botnet was published in early October. We have reviewed the source code and devised a tactic that will use the same compromise vector as the Mirai botnet to catalog vulnerable IoT devices and motivate operators to address their poor security practices. In this paper we discuss our approach and show experimental results that indicate feasibility.
Swallowing and the Upper Esophageal Sphincter

This chapter provides an overview of the normal mechanism of swallowing and the neurologic control of deglutition. The function of the upper esophageal sphincter is reviewed in the context of oropharyngeal dysphagia. A pediatric perspective is given regarding the etiology, assessment, and management of feeding and swallowing disorders.
Muroid rodent phylogenetics: 900-species tree reveals increasing diversification rates

We combined new sequence data for more than 300 muroid rodent species with our previously published sequences for up to five nuclear and one mitochondrial genes to generate the most widely and densely sampled hypothesis of evolutionary relationships across Muroidea. An exhaustive screening procedure for publically available sequences was implemented to avoid the propagation of taxonomic errors that are common to supermatrix studies. The combined data set of carefully screened sequences derived from all available sequences on GenBank with our new data resulted in a robust maximum likelihood phylogeny for 900 of the approximately 1,620 muroids. Several regions that were equivocally resolved in previous studies are now more decisively resolved, and we estimated a chronogram using 28 fossil calibrations for the most integrated age and topological estimates to date. The results were used to update muroid classification and highlight questions needing additional data. We also compared the results of multigene supermatrix studies like this one with the principal published supertrees and concluded that the latter are unreliable for any comparative study in muroids. In addition, we explored diversification patterns as an explanation for why muroid rodents represent one of the most species-rich groups of mammals by detecting evidence for increasing net diversification rates through time across the muroid tree. We suggest the observation of increasing rates may be due to a combination of parallel increases in rate across clades and high average extinction rates. Five increased diversification-rate-shifts were inferred, suggesting that multiple, but perhaps not independent, events have led to the remarkable species diversity in the superfamily. Our results provide a phylogenetic framework for comparative studies that is not highly dependent upon the signal from any one gene.
Physical factors influencing phytoplankton abundance in southern Monterey Bay

Abstract As the base of almost all marine food webs, phytoplankton play a dominant role in determining the productivity of marine ecosystems. Recent studies have highlighted the dynamic variability of phytoplankton abundance in nearshore ecosystems over synoptic time scales. Therefore, a greater understanding of the physical mechanisms that contribute to this variability is required to assess impacts of current as well as future weather patterns on these ecosystems. In this study, chlorophyll fluorescence data from a nearshore location in southern Monterey Bay was used to identify the timing and duration of increases in phytoplankton concentrations. Regional physical parameters, including wind stress, wave height and water temperature were analyzed to determine what, if any, physical processes are associated with observed blooms. A significant negative correlation between water temperature and chlorophyll (high chlorophyll associated with cold water) was found for the two summer seasons studied (2012, 2013). The timing of high chlorophyll events coincided with relaxations of upwelling favorable wind conditions. Analysis of surface current data suggests that the incoming cold water masses are the result of poleward currents from the south of Monterey Bay. A conceptual model is proposed in which phytoplankton are advected into southern Monterey Bay during wind relaxation events preceded by upwelling events of great enough duration to establish well defined circulation patterns. The reversal of circulation patterns transports cold, phytoplankton-rich water into the bay from south of the Monterey Peninsula. This study demonstrates that wind relaxation events can be an important driver of localized high phytoplankton biomass events on the inner shelf by advecting recently upwelled water into coastal embayments that are relatively sheltered from strong upwelling favorable winds.
The impact of frames highlighting coastal flooding in the USA on climate change beliefs

There is a pressing need to find ways to communicate information about climate change effectively and in terms that resonate with diverse audiences. We conducted a survey-experiment to evaluate how textual and visual frames that highlight coastal flooding in two major US cities as a result of future sea level rise shape individuals’ perceptions about the effects on coastal communities, concern for these places, and belief in climate change’s existence. We build on extant literature by focusing on the impact of an understudied frame using animated maps that illustrate future flooding that will occur as global temperatures rise. We find that exposure to such messages increases perceptions that sea level rise will have negative impacts on coastal communities, concern for these communities, and belief in climate change.
Parasacral Transcutaneous Electrical Nerve Stimulation (TENS) in Pediatric Bladder Dysfunction

Urinary incontinence, constipation, and recurrent urinary tract infections are common problems in children and constitute upwards of 40% of all pediatric urology office visits. Common treatment for these issues includes timed toileting, anticholinergics, management of constipation with dietary measures or medications, pelvic floor physical therapy, biofeedback and, at times, surgical intervention. Most of these children will demonstrate improvement in their bowel and bladder dysfunction and a decrease in the number of urinary tract infections (UTIs) with these interventions. However, in some children, alternative therapies may be indicated. One of these alternative therapies is parasacral transcutaneous electrical nerve stimulation (PTENS). Although the exact mechanism of action of PTENS remains elusive, multiple studies have shown this to be a successful treatment, which can be used in the treatment of bladder overactivity, constipation, dysfunctional voiding, and nocturnal enuresis in children. In this chapter, we review normal bladder neuroanatomy and physiology, PTENS technique and its theorized mechanism of action, as well as the indications, treatment outcomes, and side effects of PTENS in children.
Using Subgoals to Improve Student Performance in CS1: (Abstract Only)

Subgoal labels are function-based instructional explanations that describe the problem-solving steps to the learner, highlighting the solution process. There is strong evidence that the use of subgoal labels within worked examples improves student learning in other STEM fields. Initial research shows that using subgoal labels within computer science improves student learning, but this has only been tested using a single programming concept (indefinite loops) with text-based programming languages. The proposers are currently expanding subgoal labels to the main programming concepts taught in an introductory programming course using an imperative programming language. In this BOF we seek to uncover tacit knowledge that programming instructors have in order to develop instructional materials that bridge the gap between students, who are CS novices, and instructors, who are CS experts, to improve learning for students who are under-prepared for or struggle in CS1. We will be seeking feedback on the selection of programming topics to be covered, the defined subgoals for those topics and the worked examples created for instructional purposes.
OVUM COLLECTION AND INDUCED LUTEAL DYSFUNCTION IN PRIMATES

Recent advances in extracorporeal (in vitro) fertilization (IVF) and embryo transfer (ET) have demonstrated the applicability of this technique for the treatment of human infertility due to irreparable tubal dysfunction (Lopata et al., 1980; Steptoe and Edwards, 1979). However, the rate of success remains extremely limited. The reasons for frequent failures are difficult to identify and overcome because stepwise laboratory research from human gamete collection to implantation of the embryo is constrained ethically and legally in many societies (Walters, 1979). Clearly, experimental studies that consider separately each step in the sequence of IVF and ET provide maximal opportunities for improved success rates for infertile couples.
Incompleteness and Undecidability

Logical systems such as Q 0 ∞ have infinitely many theorems—indeed, infinitely many essentially different theorems—but these theorems are finitely generated. There may be infinitely many axioms, but a finite description in the meta-language suffices to specify them. Wffs are finite, and proofs are finite. Such features seem to be inescapable characteristics of logical systems which can actually be used by finite, mortal men.
Advances in Solar and Cosmic X-Ray Astronomy: A Survey of Experimental Techniques and Observational Results

The current status of X-ray astronomy is surveyed by reviewing observational results and theoretical conclusions gained within the past two years in areas dealing with the quiet-sun, slowly-varying, and burst components of solar X-radiation and with the features of cosmic X-ray sources. Thermal and nonthermal processes responsible for a wide variety of X-ray emission mechanisms in nature are explained, and characteristics of X radiation from specific solar structures are described. Attention is given to the effects of interstellar and intergalactic matter on cosmic X-rays; the properties of galactic and extragalactic X-ray sources; and the specifications of such instruments as gas-filled ionization detectors, proportional counters, Geiger counters, scintillation detectors, photoelectric detectors, polarimeters, collimators, spectrometers, and imaging systems.
A Comprehensive Time-Dependent Dielectric Breakdown Lifetime Simulator for Both Traditional CMOS and FinFET Technology

This paper presents techniques for gate-oxide and middle-of-line (MOL) time-dependent dielectric breakdown (TDDB) lifetime assessment of microprocessors and digital circuits. Both traditional CMOS and the state-of-art FinFET technology are taken into consideration. A circuit’s lifetime distribution depends on its usage and the resulting temperature profile. Emulation of the circuit operation extracts the relevant usage parameters. These parameters are converted to state probabilities at the inputs of the standard cells. The lifetime distributions of standard cells are characterized by taking into account all possible input state probabilities and die-to-die process variations. Because MOL TDDB depends on the layout, a step involved in estimating the lifetime distributions of standard cells is the analysis of the layout for MOL TDDB. Two different methods to extract the layout features are presented for traditional CMOS and FinFET technologies. By precharacterizing the standard cell lifetime distribution, our simulator can find the lifetime limiting cells in a circuit, and thus, circuit designers can replace such cells with a combination of standard cells with a longer lifetime to make the circuit more robust. The results also indicate that we need to pay more attention to the newly emerging MOL TDDB when designing new standard cells for FinFET technology.
Applicant perceptions of new selection systems are a function of their performance in the selection procedure.

Abstract Introduction Screening practices for selecting surgery trainees have been criticized for subjectivity, inefficiency, and inability to predict performance. This study explored applicant perceptions to an untraditional selection process. Methods Fellowship applicants completed an online assessment containing 26 situational judgment test (SJT) items and a 108-item personality profile. High-performing candidates participated in on-site structured interviews and skills testing. Upon completion of all interviews, but before match results were available, an anonymous, online survey was sent to all applicants. The survey asked about perceptions of the selection system along dimensions of procedural justice theory on a 1 (strongly disagree) to 5 (strongly agree) scale. Results Twenty-one of 51 applicants completed the survey. Those invited for an interview (N = 12) had more favorable perceptions about communication (3.50 ± 1.38 versus 2.00 ± 0.82,p Conclusions These results suggest that applicant perceptions are directly related to how well they perform in the selection procedure.
Beyond Orientation: A Look at Scheduled Time and Unscheduled Time in a New Librarian’s First Sixty Days

Some new librarians feel alone and are not excited about the orientation process, but library science literature is focused on this first phase of employment and its importance. This article is a self-reflection of one librarian’s allocation of scheduled time and unscheduled time in the first sixty days of employment and its possible role beyond the orientation process. The analysis of the librarian’s time within the first sixty days showed a balance between scheduled time and unscheduled time. The analysis also showed that only 5% of the first sixty days was spent in a formal orientation program. The new librarian experienced a stronger sense of employee engagement than previous positions that did not have a balanced time allocation.
Facilitated Peer Mentorship to Support Aging Research: A RE-AIM Evaluation of the CoMPAdRE Program.

Background The need for mentorship in aging research among postdoctoral trainees and junior faculty across medical disciplines and subspecialties is increasing, yet senior personnel with expertise in aging are lacking to fulfill the traditional dyadic mentorship role. Facilitated peer mentorship is grounded in collaborative work among peers with the guidance of a senior mentor. Methods and results We evaluated the Columbia University Mentor Peer Aging Research (CoMPAdRE) program, an interprofessional facilitated peer mentorship program for early stage investigators, using the Reach Effectiveness Adoption Implementation and Maintenance framework (RE-AIM). Reach: A total of 15 participants, of which 20% were women, from five states and across six medical specialties participated. Effectiveness: Participants published 183 papers, of which more than 20% were collaborative papers between CoMPAdRE mentees or mentees-mentor. Participants reported developing skills in negotiation, navigating the academic role, organizing a seminar, management, and leadership over the course of the program. According to the qualitative findings, the most important components of the program included alignment around the aging, learning from national leaders, developing leadership skills and career networking. Adoption: Individual-level factors included selecting participants with a research track record, willingness to sign a compact of commitment and involvement in shaping the program. An institutional-level factor that facilitated program adoption included strong commitment from department leaders. Implementation The program cost $3,259 per participant. Maintenance: CoMPAdRE is being maintained and currently incorporating a second cohort of mentees. Conclusion This RE-AIM evaluation provides lessons learned and strategies for future adoption, implementation, and maintenance of an aging-focused facilitated peer mentorship program.

Ureteral Replacement by Ileum

Publisher Summary This chapter focuses on the replacement ureteral by ileum. When one or both ureters are damaged beyond repair and it is impossible to restore normal continuity by the use of urinary tract tissues, it is technically possible and eminently desirable to replace the ureter with an isolated segment of small intestine. The ileum has been used in almost every conceivable way to restore the continuity of the urinary tract. It is most successful when renal function is normal and when there is no outlet obstruction. It should never be used when there is any obstruction in the lower urinary tract. Even in a normal patient, it is important to do a Y-V plastic operation to relieve any potential obstruction at the bladder outlet. The peristalsis of the ileum makes it capable of carrying urine from the kidney to the bladder.

Evolution of the Medicare Part D Medication Therapy Management Program From Inception in 2006 to the Present

Background In 2006, the Centers for Medicare & Medicaid Services (CMS) implemented the newly established Medicare Part D program that required plan sponsors to offer a medication therapy management (MTM) program. The MTM program requirements have become more prescriptive over the past decade in the attempt to address low beneficiary enrollment rates, improve the quality of services provided, and address gaps in meeting the needs of enrollees. Objective To describe changes to the requirements for the Medicare Part D MTM program since its inception in 2006 and the impact of these changes to inform future program enhancements. Methods We obtained publicly available information extracted from the Medicare Part D MTM program fact sheets for the years 2008 through 2018, in addition to searching indexed literature through PubMed and additional literature through Internet searches. We then categorized the program's requirement changes annually, and described the Part D MTM program characteristics and reported statistics. Discussion Significant changes to the Part D MTM program requirements occurred in 2010, 2013, and 2016 regarding eligibility criteria, MTM services, and reporting requirements. Thresholds to determine beneficiary eligibility have been lowered. Specific MTM services now include an annual comprehensive medication review, followed by a written summary using the Standardized Format. Quarterly targeted medication reviews are also required. Reporting requirements now include comprehensive medication review completion rates and the number of prescriber interventions, among others. Despite more prescriptive MTM program requirements, the low utilization of the MTM program continues. Conclusion Low beneficiary enrollment rates in the Medicare Part D MTM program led CMS to lower thresholds required for eligibility to expand the beneficiary pool. More prescriptive MTM service requirements enhanced service standardization. Despite these changes, MTM enrollment and comprehensive medication review rates remain low, likely, in part, from a lack of financial incentives. The Enhanced MTM program is a 5-year test model that is providing participating Part D plans regulatory flexibility and financial incentives to design their own MTM programs, to evaluate the impact of different program designs on beneficiary engagement and outcomes.

Low-Rank Nonlinear Decoding of $\mu$-ECoG from the Primary Auditory Cortex

This paper considers the problem of neural decoding from parallel neural measurements systems such as micro-electrocorticography ($\mu$-ECoG). In systems with large numbers of array elements at very high sampling rates, the dimension of the raw measurement data may be large. Learning neural decoders for this high-dimensional data can be challenging, particularly when the number of training samples is limited. To address this challenge, this work presents a novel neural network decoder with a low-rank structure in the first hidden layer. The low-rank constraints dramatically reduce the number of parameters in the decoder while still enabling a rich class of nonlinear decoder maps. The low-rank decoder is illustrated on $\mu$-ECoG data from the primary auditory cortex (A1) of awake rats. This decoding problem is particularly challenging due to the complexity of neural responses in the auditory cortex and the presence of confounding signals in awake animals. It is shown that the proposed low-rank decoder significantly outperforms models using standard dimensionality reduction techniques such as principal component analysis (PCA).
Financial Risk Attitude and Behavior: Do Planners Help Increase Consistency?

This study is the first to evaluate the effect of sources of information on households’ consistency between their risk attitude when making savings and investment decisions and risk behavior displayed when they do save and invest. As the responsibility is being shifted to individuals to save for their own financial future, it is important that individuals and households save and invest in a manner that is consistent with their financial risk tolerance. Financial planners were found to provide significant value to households on the consistency of their financial risk attitude and behavior. The implications of this work are far-reaching in the financial planning arena.
Psychological distress and alcohol use disorder during the COVID-19 era among middle- and low-income U.S. adults.

Abstract Purpose This study examined how exposure to events during the Coronavirus Disease-19 (COVID-19) era is linked to symptoms of major depressive disorder (MDD), generalized anxiety disorder (GAD), COVID-19 era-related stress (CS), alcohol use disorder (AUD), and suicidal ideation (SI) in low and middle-income U.S adults. Methods A national sample of 6,607 adults (4.4% who reported testing positive for COVID-19, 25.3% testing negative, and 70.3% untested) were recruited an online platform andcompleted the Patient Health Questionnaire-2, Generalized Anxiety Disorder-2, PTSD-Checklist for DSM-5, the Alcohol Use Disorder Identification-Consumption scale, and an item assessing SI in May-June 2020. A series of multivariable analyses were conducted. Results In the total sample, 35.3% screened positive for current AUD, 33.6% for MDD, 33.6% for GAD, 24.6% for SI, and 20.2% for CS. Past 2-week SI (adjusted odds ratios [AORs]= 1.49–12.06), number of close friends (AORs= 1.40–2.72), history of AUD (AORs= 1.15–1.92), history of anxiety disorder (AORs= 1.07–2.63), and younger age (AORs= 0.97–0.98) were significantly associated with screening positive for MDD, GAD, CS, and AUD. COVID-19 status was not independently associated with these conditions, but the combination of testing positive for COVID-19, meeting criteria for AUD, and screening positive for MDD, GAD, or CS predicted a 96% probability for SI. Conclusion Predisposing factors are stronger predictors of psychological distress than personal COVID-19 infection or exposure. The additive effects of COVID-19 infection, alcohol use, and psychiatric problems in predicting SI suggest screening, monitoring, and treating these conditions in population-based prevention and treatment efforts may be important.
FarOut Touch: Extending the Range of ad hoc Touch Sensing with Depth Cameras

The ability to co-opt everyday surfaces for touch interactivity has been an area of HCI research for several decades. Ideally, a sensor operating in a device (such as a smart speaker) would be able to enable a whole room with touch sensing capabilities. Such a system could allow for software-defined light switches on walls, gestural input on countertops, and in general, more digitally flexible environments. While advances in depth sensors and computer vision have led to step-function improvements in the past, progress has slowed in recent years. We surveyed the literature and found that the very best ad hoc touch sensing systems are able to operate at ranges up to around 1.5 m. This limited range means that sensors must be carefully positioned in an environment to enable specific surfaces for interaction. In this research, we set ourselves the goal of doubling the sensing range of the current state of the art system. To achieve this goal, we leveraged an interesting finger ”denting” phenomena and adopted a marginal gains philosophy when developing our full stack. When put together, these many small improvements compound and yield a significant stride in performance. At 3 m range, our system offers a spatial accuracy of 0.98 cm with a touch segmentation accuracy of 96.1%, in line with prior systems operating at less than half the range. While more work remains to be done to achieve true room-scale ubiquity, we believe our system constitutes a useful advance over prior work.
Variability of in vivo sarcomere length measures in the upper limb obtained with second harmonic generation microendoscopy

The lengths of a muscle9s sarcomeres are a primary determinant of its ability to contract and produce force. In addition, sarcomere length is a critical parameter that is required to make meaningful comparisons of both the force-generating and excursion capacities of different muscles. Until recently, in vivo sarcomere length data have been limited to invasive or intraoperative measurement techniques. With the advent of second harmonic generation microendosopy, minimally invasive measures of sarcomere length can be made for the first time. This imaging technique expands our ability to study muscle adaptation due to changes in stimulus, use, or disease. However, due to the prior inability to measure sarcomeres outside of surgery or biopsy, little is known about the natural, anatomical variability in sarcomere length in living human subjects. To develop robust experimental protocols that ensure data provide accurate representations of a muscle9s sarcomere lengths, we sought to quantify experimental uncertainty associated with in vivo measures of sarcomere lengths. Specifically, we assessed the variability in sarcomere length measured 1) within a single image, along a muscle fiber, 2) across images captured within a single trial, across trials, and across days, as well as 3) across locations in the muscle using second harmonic generation in two upper limb muscles with different muscle architectures, functions, and sizes. Across all of our measures of variability we estimate that the magnitude of the uncertainty in in vivo sarcomere length are on the order of 0.25 microns. In the two upper limb muscles studied we found larger variability in sarcomere length within a single insertion than across locations. We also developed custom code to make measures of sarcomere length variability across a single fiber and determined that this codes9 accuracy is an order of magnitude smaller than our measurement uncertainty due to sarcomere variability. Together, our findings provide guidance for the development of robust experimental design and analysis of in vivo sarcomere lengths in the upper limb.
A Specific Example of a Rearrangement Collision: The (d, p) Reaction on Nucleus A

To show in detail how the rearrangement collision integrals are calculated, we shall study the (d, p) reaction on nucleus A, e.g., 16 O, to make nucleus B, e.g., 17 O, that is, a nucleus in which the extra neutron captured by nucleus A orbits this nucleus in a particular shell model orbit with orbital angular momentum, L.

Octree data structures and creation by stacking

Efficient, compact data structures are necessary for the representation of octrees. First, several concrete data structures for the octree abstract data type will be compared in terms of storage space required and execution time needed to perform operations such as to find a certain node or obei. We compare information theoretic minimal representations, digital search trees sometimes storing some information in an immediate mode without pointers, and storing the set of rays, which is often the most compact.
Chest radiographic findings in pediatric patients with intraluminal pulmonary vein stenosis.

Early recognition of pulmonary vein stenosis (PVS) is crucial for optimizing clinical outcomes. Our goal was to characterize radiographic patterns specific to pediatric patients with PVS to facilitate early detection. Patients and Methods Pediatric patients with multivessel (≥2) intraluminal PVS were identified from a single-center registry. Initial chest radiographs were reviewed. Radiographic findings were summarized using frequencies and percentages for categorical data, and medians and ranges for continuous data. Interrater agreement was assessed using kappa statistics. Results Chest radiographs of 41 PVS patients were evaluated; median age at presentation 5.2 (0.5–102.6) months. Underlying congenital heart disease was present in 31 (76%), lung disease in four (10%), and neither in six (15%). Common heart diseases were hypoplastic left heart syndrome (five, 12%), totally anomalous pulmonary venous connection (nine, 22%), and heterotaxy (five, 12%). PVS was bilateral in 22 (54%), right-sided in six (14%), and left-sided in 13 (32%). All chest radiographs were abnormal. Increased interstitial opacity was present in all patients, reticular opacity in 35 (85%), and ground-glass opacity in 29 (71%). Consolidation (one, 2%), pleural effusions (four, 10%), and nodular opacities (0) were unusual. Distributional heterogeneity was common (17, 42%). Interrater agreement was generally high (kappa >0.84) except for lobe location. Findings were similar among patients with isolated PVS, PVS with congenital heart disease, and PVS with lung disease. Conclusion Diagnosis of PVS should be considered in infants with increased interstitial opacity, reticular opacity, and ground-glass opacity on chest radiography, especially if findings are heterogeneous.
Rapid mapping of AR coating thickness on Si solar cells using GT-FabScan 6000

A new technique for rapid mapping of the thickness, of an antireflection (AR) coating on a solar cell is described. A filtered, reflectance (intensity) image of the AR-coated wafer is generated by a CCD camera mounted on a GTFabScan. This image is converted into a thickness image using a transformation relating local AR thickness to the local intensity in the image plane. The thickness map is generated in <100 ms.
Somatic Mutations in Polycythaemia Vera and Other Philadelphia Chromosome Negative Myeloproliferative Neoplasms

The just another kinase (JAK) family kinases function as the cognate tyrosine kinases for Type I/II cytokine receptors that lack intrinsic kinase domains. Perhaps the most important is JAK2, which is also a chaperone for the erythropoietin and thrombopoietin receptors as well as the kinase utilised alone or with other JAK kinases in the majority of cytokine receptors. JAK2 can be considered an oncogene because it is responsible for promoting cell proliferation and preventing apoptosis and its constitutive activation causes acute and chronic leukaemias and lymphomas. The most common JAK2-activating mutation, V617F, is responsible for the clinical phenotype of polycythaemia vera and that of approximately 50% of cases of essential thrombocytosis and primary myelofibrosis. In recent studies of JAK2 inhibitors in primary myelofibrosis there was amelioration of clinical symptoms and a reduction in splenomegaly, supporting an important role of JAK2 in the myeloproliferative phenotype and identifying a new treatment for these disorders. Key Concepts: The Janus kinase family has a crucial role in hematopoietic and immune cell function. JAK2 V617F-activating mutation is the most frequent genetic alteration in polycythaemia vera, essential thrombocytosis and primary meylofibrosis. JAK2 V617F has oncogenic properties and is responsible for uncontrolled cell proliferation, inhibition of apoptosis, genetic instability via induction of proto-oncogenes, reactive oxygen species and promotion of mitotic recombination. JAK2 exon 12 mutations are frequent in JAK2 V617-negative polycythaemia vera patients. JAK2 mutation alone cannot entirely explain the disease phenotype in the myeloproliferative disorders and genetic predisposition seems to play an important role in both the acquisition of these mutations and disease pathogenesis. The role of JAK2 V617F mutation as a marker for disease prognosis is unresolved. JAK2 inhibitors improve constitutional symptoms and reduce splenomegaly in primary myelofibrosis patients.

Thinking Like a Public Interest Lawyer: Theory, Practice and Pedagogy

In educating future public interest lawyers, law schools must cultivate in students the combination of intellectual, emotional, and normative thinking required for the complex world of practice. This article presents one such method for teaching critical public interest lawyering: the integration of social theory and public interest practice introduced by the Harvard Law School Summer Theory Institute. The theory-practice method of the Institute, in which law students engage with social theories while participating in full-time summer internships with public interest organizations, demonstrates the benefits of creating a space for students to draw connections between abstract conceptions of justice and on-the-ground efforts to lawyer for social change. This article begins by using the theories of Pierre Bourdieu to explore a dichotomy between theory and practice in public interest law that can often inhibit efforts to pursue social justice lawyering. Then, drawing upon the discussions the Summer Theory Institute’s students had about three theorists – Michel Foucault, Friedrich Hayek, and David Couzens Hoy – this article demonstrates how theoretical reflection placed in the practice setting can cultivate in law students the kind of normative thinking necessary to make them inspired, self-reflective, and critically engaged public interest lawyers and agents of social change.
Side impact sled and padding development

Crush tests were conducted with specially designed body forms into the side interior door of VW Rabbits previously crashed in side impact studies. An acceleration-type sled buck was built with an "interior door" mounted to mimic the interior stiffness determined from the crush tests. The sled was dynamically tested with a Haversine sled pulse similar to the door crash pulse, and was validated by reproducing the crash environment of a car-to-car collision. Validation criteria included acceleration-time and velocity-time curves of the interior door, kinematics of the Pt. 572 surrogate, and accelerations on the surrogate. Using the sled and a new side impact dummy, numerous energy-absorbing materials were tested as interior door padding. The following six types of padding gave the best performance in terms of AIS (Abbreviated Injury Scale) B parameter (acceleration of the left upper rib): Ensolite ABC, Fiberglas H3BC, Rubatex 2VS and R-310-V, GTREM, APR, and Durafoam C222A. The AIS values ranged from 3.2 to 3.5 (VW Rabbit traveling at 15 mph and impacted in the door area at 30 mph by an intermediate size vehicle at an impact angle 60 degrees from the forward longitudinal axis). The padding types ranked highest in upper spine 3 msec. clip acceleration tests were Durafoam C222A, Fiberglas H3BC, Ensolite AAC, APR, Rubatex R-310-V, and GTREM. The spinal accelerations ranged from 40 to 45 g's.
An Algorithm for Mining Weighted Dense Maximal 1-Complete Regions

Summary. We propose a new search algorithm for a special type of subspace clusters, called maximal 1-complete regions, from high dimensional binary valued datasets. Our algorithm is suitable for dense datasets, where the number of maximal 1-complete regions is much larger than the number of objects in the datasets. Unlike other algorithms that find clusters only in relatively dense subspaces, our algorithm finds clusters in all subspaces. We introduce the concept of weighted density in order to find interesting clusters in relatively sparse subspaces. Experimental results show that our algorithm is very efficient, and uses much less memory than other algorithms.
