Evidence of Atmospheric Contamination on the Measurement of the Spectral Response of the GMS-5 Water Vapor Channel

Abstract The GMS-5 geostationary satellite carries a channel centered at 6.7 μm for the measurement of upper-tropospheric humidity. This channel’s spectral response shows structures that are similar to those shown by the atmospheric transmission. This note shows that these structures probably result from water vapor absorption between the calibration source and the instrument while making the response measurement. A corrected filter is proposed after normalization by the inferred atmospheric transmission. The brightness temperatures computed by a radiative transfer model using the spurious response exhibit a warm bias of about 1 K.
Approaches to high-speed networks

This work investigates possible methods by which existing potentially available communication bandwidth can be used by communication intensive applications. Presently fiber optic media are available that can provide multiple gigabits of throughput. Unfortunately, because of the computation overhead required to insure that data are reliably transmitted this capacity has not been tapped. A survey of work toward enabling the use of the potential bandwidth is presented. The parallel paradigm is identified as a strong candidate for providing significant increases in system usable bandwidth. Performing communication processing in parallel, however, presents the developer with several implementation options. These options are considered and categorized. This categorization represents a framework that is used in later analysis to compare different approaches and architectures. Because the number of options available represents a combinatorial explosion in the number of software and hardware architectures that could be implemented, a sensitivity analysis is performed to exclude obvious failures, as well as to identify those components that need further study and close consideration. Some components are identified as limiters to total throughput obtainable; these components warrant special attention when implementing a parallel communication system. Building on results obtained through the sensitivity analysis, a testbed was then built and used to obtain performance data for one promising architecture and approach. The results for two and three channels implementations show near linear speedups. These results were then used to verify a model of the system used to calculate throughput values for systems with higher numbers of channels. In order to more fully examine other promising architectures, a simulation program was developed and exercised. The simulation examined the impact of traditional communication parameters, such as window size and timer length, on performance in a parallel system. Further, the simulation confirmed some of the results of the sensitivity analysis and provided insight to the viability of two algorithms to implement flow control in a parallel environment. Additionally, scheduling algorithms to allocate processors to the communication tasks are examined and performance results are presented.
The Role of Education in the Development of Cultural Competency in Dental Hygiene Students.

This study seeks to determine if students who completed the 2-year dental hygiene program at the University of Tennessee Health Science Center developed in the area of cultural competency, as measured by the Cross-Cultural Adaptability Inventory (CCAI). In addition, this study attempts to ascertain if certain socioeconomic factors influence the development of cross-cultural competency. The sample consisted of a cohort of 32 students enrolled from 2003-2005. Descriptive statistics, ANOVA procedures, dependent t-test, and independent t-test were calculated to determine results. The CCAI is a 50-item instrument that determines one9s cross-cultural adaptability based on 4 constructs: emotional resilience (ER), flexibility/openness (FO), perceptual acuity (PAC), and personal autonomy (PA). The overall CCAI score is computed from the sum of the 4 dimensional scores. The CCAI pre-test was administered to the dental hygiene cohort at the beginning of the 2-year program, followed by the post-test, which was administered prior to program completion. Results of this study revealed minimal evidence of increase in the overall CCAI post-test score (p = .085). The t tests revealed no significant change between pre-test and post-test scores for 3 of the 4 subscales (ER, PAC, and PA) at the .05 level. However, at the .05 level, the FO scale indicated significant change between the pre-test (M = 65.09, SD = 7.67) and post-test scores (M=67.96, SD = 7.81). Lastly, this study found no significant changes in the CCAI pre-test and pos-test scores based on 2 socioeconomic factors, current family status, or parent9s educational levels. The study concluded that the integration of culture-related topics in the educational program is both appropriate and effective. Providing frequent clinical experiences that allow students to interface with diverse populations is an effective strategy for increasing flexibility and openness, one construct of cultural competency.
What Do Trade Negotiators Negotiate About? Some Evidence from the Uruguay Round

Krugman (1991, 1997) argues that international trade negotiations are based on mercantilist rules. Bhagwati (1988, 1995) highlights how nations are obsessed with reciprocity in their bargaining. Based on studying the trade negotiations process and the results of the Uruguay Round, we provide some answers to the following questions: How did trade negotiators negotiate? What did they negotiate about? We also provide some econometric results based on the Nash bargaining model of Binmore, Rubinstein and Wolinsky (1986) and also partly on the theory of trade talks by Grossman and Helpman (1995). We found that what a country got in concessions relative to what it gave was positively related to its import-to-GNP ratio, but negatively related to its export-to-GNP ratio and also negatively related to its GNP. The last result can be interpreted to provide some support for the "hegemon hypothesis:" to help maintain the world trading system, large countries tend to give more net concessions than small countries.
Mechanism of 1,3-dichloropropene-induced rat liver carcinogenesis.

1,3-Dichloropropene (1,3-D) is a soil fumigant used primarily for preplanting control of parasitic nematodes. In a previous chronic dietary exposure study, 1,3-D induced an increased incidence of hepatocellular adenomas in male rats at a dose of 25 mg/kg/day. Although the mechanism for tumor induction in the rat liver by 1,3-D has not been specifically elucidated, available data suggested that the observed liver tumorigenesis was through a nongenotoxic mode of action at the tumor promotion stage. Fischer 344 rats containing preneoplastic lesions were treated (via gavage) with 25 mg/kg/day 1,3-D or 80 mg/kg/day phenobarbital (PB) for 30 days and 60 days, or for 30 days followed by a 30-day recovery period (no compound exposure). Following treatment, placental form glutathione S-transferase (GSTP) positive and GSTP-negative liver focal lesions were quantitated as to size and number. 1,3-D treatment had no effect on GSTP-positive foci number or relative size but significantly increased the number, labeling index, and relative size of GSTP-negative focal lesions (identified by H and E staining) after 30 and 60 days of treatment. Following the 30-day recovery period, the number, labeling index, and relative size of the GSTP-negative lesions in 1,3-D-treated animals returned to control levels. As expected, PB treatment produced an increase in number and relative size of the GSTP-positive lesions. The results of this study are consistent with 1,3-D inducing liver carcinogenesis through a nongenotoxic mode of action by functioning as a tumor promoter specifically through induction of a non-GSTP staining focal hepatocyte population.
Occurrence and Prognostic Significance of Pseudodissection Phenomenon Associated with Acute Distal Internal Carotid Artery Occlusion (P07.011)

Objective: To determine the angiographic characteristics of the phenomemon of “pseudodissection” and its clinical implications in acute stroke endovascular treatment. Background Acute stroke from intracranial internal carotid artery (ICA) occlusion can occasionally resemble angiographic cervical ICA dissection which may cause delays in endovascular acute stroke treatment. Design/Methods: Retrospective analysis of angiographic and clinical data of 31 patients with acute stroke from ICA occlusion, treated with endovascular therapy at two University affiliated institutions was performed. Pseudodissection was defined as angiographic appearance of typical ICA dissection with evidence of normal inner vascular wall upon further catheter exploration. Results: Angiographic appearance pseudodissection was identified in 7 out of 31 patients (22.6%). Six patients had guide catheters placed proximal to pseudodissection in anticipation of stent placement for treatment of dissection. All 7 patients had further exploration of the presumed dissected segment (6 microcatheter, 1 diagnostic catheter) which demonstrated normal vascular inner wall. The location of the clot was more common in the petro-cavernous segment in the pseudodissection patients (5/7, 71%). Carotid terminus clot was more common in non pseudodissection patients compared to pseduodissection patients (18/24, 75% versus 2/7, 29% respectively, p Conclusions: Early recognition of pseudodissection in the ICA is important in the setting of acute stroke to avoid delay in treatment of intracranial ICA occlusion.

Artificial Infestation of Corn with Western Corn Rootworm Eggs in Agar-Water

The following 4 aspects of the efficacy of the wet method (suspension of eggs in agar-water) and the earlier dry method (mixture of eggs in dry fine soil) for infesting corn with eggs of Diabrotica vergifera LeConte were compared: homogeneity of mixtures; viability of eggs after extended periods in the mixtures; results of artificial field infestation of corn; and time requirement for preparing the mixtures. Results indicated that the agar-water method gave a much more homogeneous mixture, methods had no adverse effect on egg hatch when stored at 10°C for up to 30 days, there was no significant difference in mean numbers of corn rootworms per plant and mean root damage ratings between the wet and dry methods of field infestation of corn, and the wet method can be prepared in half of the time and would save much time.

Descriptions of two new species, Mysidopsis badius and Heteromysis tuberculospina, are presented.
Tricuspid annular plane systolic excursion is preserved in young patients with pulmonary hypertension except when associated with repaired congenital heart disease.

Aims Tricuspid annular plane systolic excursion (TAPSE) is a measure of right ventricular (RV) longitudinal function that correlates with functional status and mortality in adults with pulmonary hypertension (PH). The diagnostic and predictive value of TAPSE in children with PH has not been fully examined. We aimed to define TAPSE across aetiologies of paediatric PH and assess the correlation between TAPSE and measures of disease severity. Methods and results TAPSE measurements were obtained in 84 children and young adults undergoing treatment for PH and 315 healthy children to establish z-scores at moderate altitude for comparison. The relationships between TAPSE and echocardiographic, biomarker, and functional measures of disease severity between aetiologies were assessed. TAPSE z-scores in PH patients with congenital heart disease (CHD) repaired with open cardiac surgery ( n = 20, mean −2.73) were significantly decreased compared with normal children and patients with other aetiologies of PH ( P < 0.001) but did not reflect poorer clinical status. TAPSE z-scores in children with idiopathic PH ( n = 29, −0.41), unrepaired CHD ( n = 11, −0.1), and PH related to systemic disease ( n = 14, −0.39) were not different from normal. TAPSE correlated modestly with brain natriuretic peptide, echocardiographic function parameters, and functional class except in patients with repaired CHD. Conclusion Children with PH maintain normal TAPSE values early except when associated with repaired CHD. Superior RV adaptation to high afterload in children compared with adults may account for this finding. Reduced TAPSE after repair of CHD does not correlate with functional status and may reflect post-operative changes rather than poor function primarily due to PH.
Epidemic Situation of Chronic Filariasis After Filariasis Being Eliminated in Meishan

Objective To master the onset and prognosis of chronic filariasis cases after the disease being eliminated,so as to provide the basis for case care.Methods After the filariasis being basically eliminated,the subjects from 3 epidemic counties older than age 10 were visited and underwent medical examination one by one.The original chronic filariasis cases were investigated and checked one by one in 2011.Results When filariasis was basically eliminated in Meishan in 1983,there were 393 chronic filariasis cases,and still there were respectively 86 and 29 cases in 1996 and 2011.The cases in 2011 were naturally reduced by 92.62% and 66.28% than that when the disease was basically eliminated and eliminated,respectively.The distribution area shrank(from 313 groups in the 111 villages of 32 townships before the prevention-control to 28 groups in 25 villages of 14 townships in 2011),with no new chronic filariasis case in 2011.Those over 70 years old among the retained 29 cases accounted for 82.76 %,with a course over 30 years.The lymphedema mainly involved the unilateral lower extremities,accounting for 75.86% of the total.The stage of limb lymphedema was Ⅰ-Ⅱ stage accounted for 86.21%.The rate of chronic filariasis cases correlated positively with that of microfilaria among original group.Conclusion After filariasis being eliminated,the original chronic filariasis cases significantly reduced due to aging,sickness and death.The symptoms of degree significantly mitigated and the characteristics of performance of them were old age,long duration.During the later stage of filariasis surveillance,the care measures towards the patients should be strengthened.
SystemVerilogCSP: Modeling Digital Asynchronous Circuits Using SystemVerilog Interfaces

This paper describes how to model channel-based digital asynchronous circuits using SystemVerilog interfaces that implement CSP-like communication events. The interfaces enable explicit handshaking of channel wires as well as abstract CSP events. This enables abstract connections between modules that are described at different levels of abstraction facilitating both verification and design. We explain how to model one-to-one, one-to-many, one-to-any, any-to-one and synchronised channels. Moreover, we describe how to split communication actions into multiple parts to model more accurately less concurrent handshaking protocols that are commonly found in many asynchronous pipelines.
Infiltration vs. Surface Water Discharge: Development of Guidance for Stormwater Managers

Stormwater managers are increasingly faced with the need to address many potentially-conflicting issues as part of their activities, ranging from flood prevention to protection of downstream habitat. New philosophies, such as a post-development goal of mimicking pre-development hydrology, have been promoted as addressing both the goals of water quality and water quantity control. These new management plans incorporate both infiltration and surface treatment/discharge into the development. A flowchart was developed to aid stormwater managers in stepping through the process of selecting an appropriate management/treatment technology.

Echocardiographic Ischemic Memory Imaging Through Complement-Mediated Vascular Adhesion of Phosphatidylserine-Containing Microbubbles

Abstract Objectives This study hypothesized that microvascular retention of phosphatidylserine-containing microbubbles (MB-PS) would allow detection of recent but resolved myocardial ischemia with myocardial contrast echocardiographic (MCE) molecular imaging. Background Techniques for ischemic memory imaging which can detect and spatially assess resolved myocardial ischemia are being developed for rapid evaluation of patients with chest pain. Methods MCE molecular imaging with MB-PS was performed 1.5 h, 3.0 h, and 6.0 h after brief (10 min) myocardial ischemia in mice; data were compared to selectin-targeted microbubbles. MCE molecular imaging with Sonazoid (GE Healthcare, Amersham, United Kingdom), a commercially produced phosphatidylserine (PS) − containing agent, was performed in separate mice at 1.5 h and 3.0 h after ischemia-reperfusion; and in dogs undergoing 135 min of ischemia and 60 min of reflow as well as in closed-chest nonischemic control dogs. The mechanism for MB-PS attachment was assessed by intravital microscopy of post-ischemic muscle and by flow cytometry analysis of cell-MB interactions. Results In mice undergoing ischemia-reperfusion without infarction, signal enhancement in the risk area for MB-PS and p-selectin glycoprotein ligand-1−targeted microbubbles was similar at reflow times of 1.5 h (23.3 ± 7.3 IU vs. 30.7 ± 4.1 IU), 3.0 h (42.2 ± 6.2 IU vs. 33.9 ± 7.4 IU), and 6.0 h (24.1 ± 4.3 IU vs. 25.5 ± 4.7 IU). For both agents, signal in the risk area was significantly (p 5-fold higher than in closed-chest control myocardium (42.2 ± 8.1 IU vs. 7.9 ± 3.3 IU; p Conclusions Ischemic memory imaging with MCE is possible using MB-PS which may obviate the need for ligand-directed targeting.
The Impact of Biochemical Markers on Major Adverse Cardiovascular Events and Contralateral Carotid Artery Stenosis Progression Following Carotid Interventions

Backgroud To determine if elevated preintervention high-sensitivity C-reactive protein (hsCRP) and B-type natriuretic peptide (BNP) levels associate with major adverse cardiovascular events (MACE) or disease progression after carotid revascularization. Methods We retrospectively examined patients receiving elective carotid endarterectomy (CEA) or carotid artery stenting (CAS) at our institution from 2007 to 2014. All included patients had preintervention hsCRP and BNP levels. Examined outcomes of interest included contralateral carotid disease progression (increased stenosis or need for revascularization) and MACE (composite of death, stroke, myocardial infarction, need for coronary artery bypass graft or percutaneous coronary intervention) at 3 years after procedure. The relationship between baseline hsCRP and BNP levels and time to event was examined by univariate and multivariate Cox proportional hazard regression analyses. Results A total of 248 patients were included in the analysis (mean age: 68 ± 10 years), with 14% receiving CAS and 86% CEA. A total of 61 patients (25%) had 1 or more MACE by 3 years. Elevated hsCRP (>3 mg/L) trended toward associating with MACE but failed to reach significance (hazard ratio [HR]: 1.6 [1.0–2.7], P = 0.07). Multivariate analysis found that elevated BNP (>100pg/mL, HR: 2.2 [1.3–3.7], P = 0.002) and diabetes mellitus (HR: 1.9 [1.2–3.2], P = 0.01) predicted MACE. Having elevated preprocedural levels of both hsCRP and BNP significantly increased patients' likelihood of experiencing MACE (HR: 3.4 [1.6–7.1], P = 0.001). About 175 patients received contralateral carotid imaging postprocedure and of those patients, 31 (18%) experienced stenosis progression and/or revascularization within 3 years. However, neither elevated hsCRP (HR: 1.2 [0.6–2.3], P = 0.68) nor BNP (HR: 1.1 [0.5–2.5], P = 0.88) associated with disease progression. Conclusions BNP elevation at the time of carotid intervention is associated with MACE in long-term follow-up. hsCRP does not appear to correlate with either disease progression of the contralateral artery or MACE.
Precisiones literarias sobre el antijudaísmo de Gonzalo de Berceo en el Milagro de Teófilo (XXIV)

In the medieval Marian collection Los Milagros de Nuestra Senora (Miracles of Our Lady) by Gonzalo de Berceo, the Milagro de Teofilo (The Miracle of Teophilus) is the most extensive and elaborate. The poem, which enjoyed wide circulation in other European vernacular languages, contains a moralizing didactic message aimed at the readership in order to prevent any contact with the Devil and his followers. In this case, it is a Jew who acts as an intermediary between Teofilo and Satan. However, whereas the rest of the European versions portray anti-Semitic features on the Jewish character influenced by popular folklore, such as embodying an evil animal-like creature involved in diabolical practices, these references are absent in Berceo’s version. Berceo’s position with respect to the Jew stands out as one based essentially on anti-Jewish traits inherited from Patristic and other traditional clerical thought. Hence, it lacks anthropological and racial prejudices common to anti-Semitism in the rest of Europe and which were unknown in the Iberian Peninsula imaginary at least for the following two centuries.
Interlude: The Neurobiological Image

In the effort to articulate a conceptually adequate and empirically informed analysis of the first-person structure of experience, Part One focused on philosophy of mind and cognitive science. Part Two now shifts to philosophy of biology and embodiment. What emerges is a sort of neurobiological image of human subjectivity; a neurophilosophy, broadly construed. In the neurobiological image, we are hide-bound animal subjects, neurologically enabled, ecologically situated, and historically conditioned. It seems to me that this neurobiological image is already out there in the zeitgeist. Increasingly, it guides thinking about human life across the sciences, social sciences, humanities, and the culture at large. In the following chapters I place the neurobiological image in a theoretical framework and discuss its implications.
LC-MS/MS suggests that hole hopping in cytochrome c peroxidase protects its heme from oxidative modification by excess H2O2

We recently reported that cytochrome c peroxidase (Ccp1) functions as a H2O2 sensor protein when H2O2 levels rise in respiring yeast. The availability of its reducing substrate, ferrocytochrome c (CycII), determines whether Ccp1 acts as a H2O2 sensor or peroxidase. For H2O2 to serve as a signal it must modify its receptor so we employed high-performance LC-MS/MS to investigate in detail the oxidation of Ccp1 by 1, 5 and 10 M eq. of H2O2 in the absence of CycII to prevent peroxidase activity. We observe strictly heme-mediated oxidation, implicating sequential cycles of binding and reduction of H2O2 at Ccp1's heme. This results in the incorporation of ∼20 oxygen atoms predominantly at methionine and tryptophan residues. Extensive intramolecular dityrosine crosslinking involving neighboring residues was uncovered by LC-MS/MS sequencing of the crosslinked peptides. The proximal heme ligand, H175, is converted to oxo-histidine, which labilizes the heme but irreversible heme oxidation is avoided by hole hopping to the polypeptide until oxidation of the catalytic distal H52 in Ccp1 treated with 10 M eq. of H2O2 shuts down heterolytic cleavage of H2O2 at the heme. Mapping of the 24 oxidized residues in Ccp1 reveals that hole hopping from the heme is directed to three polypeptide zones rich in redox-active residues. This unprecedented analysis unveils the remarkable capacity of a polypeptide to direct hole hopping away from its active site, consistent with heme labilization being a key outcome of Ccp1-mediated H2O2 signaling. LC-MS/MS identification of the oxidized residues also exposes the bias of electron paramagnetic resonance (EPR) detection toward transient radicals with low O2 reactivity.
Entry Points and Trailheads: Pondering the History and Future of the William P. Clements Center for Southwest Studies

Since its establishment in the fall of 1996, the William P. Clements Center for Southwest Studies at Southern Methodist University in Dallas, Texas, has served as a key incubator of first-rate scholarship on Texas and the transnational U.S.-Mexico borderlands. Although its visionary founding director, David J. Weber, died in August 2010 (his final article appears in this issue of Western Historical Quarterly ), the core mission of the center remains the same. As Weber's successor, I describe the annual operations of the Clements Center while touching on some of my own ideas about the future of this vital academic institute.
Continual Business Transformation Technology

Enterprises always have to pursue for profitability while maintaining long term competitive advantages. Today, this task becomes more challenging due to globalization and dynamic changing business environment. For each enterprise, this task can not be fulfilled without changes to its business infrastructure and IT systems. That is, enterprises need to transform themselves to adapt to both external and internal changes. This kind of transformation is not simply any transactional act, but rather a never-easy journey. In this paper, the concept of continual business transformation is introduced with key challenges identified. Based on experience from practical cases, we propose a set of business transformation technology framework that incorporates component-based approach and business-driven architecture. In the framework, CBM (Component Business Modeling) method is to identify transformation opportunities and provide guidance to IT architecture design from business perspectives. As transformation needs to be conducted in a holistic view, IT Blueprint in the framework is to provide an enterprise-wide IT design and governance model. To avoid building more silo applications as happening today in many cases, the IT Blueprint can be used to guide solution development for better alignment among different applications as well as across various stages during the transformation. Another keystone in the framework is Assetization, which is proposed for quality improvement and cost reduction from harvesting and reusing artifacts built in the transformation journey. Furthermore, we also illustrate how these methods and technologies were validated in a transformation engagement with a leading international bank in Asia-Pacific with satisfactory results.
5-Azadibenzo[a,g]corannulene

5-Azadibenzo[a,g]corannulene, the first azacorannulene with a nitrogen on the rim, has been synthesized in seven steps from 4-bromoisoquinoline. The strained pyridine ring opens thermally to a polycyclic aromatic nitrile and hydrolytically to an amino aldehyde with the same polycyclic aromatic hydrocarbon framework.
Long-term hormonal contraceptive use is associated with a reversible suppression of antral follicle count and a break from hormonal contraception may improve oocyte yield.

Unlike infertility, patients presenting for fertility preservation (FP) are often using combined hormonal contraceptives (CHC). We studied whether long-term (≥6 months) CHC use is associated with reversible suppression of antral follicle count (AFC). This is a longitudinal study of FP cycles from 2012 to 2016. We studied three groups: those without CHC exposure (NO CHC), those with CHC usage with a CHC break (BREAK), and without a break (NO BREAK) prior to ovarian stimulation. We assessed ovarian reserve by AFC at initial consultation and discussed the possibility of CHC suppression of AFC. Patients chose between ovarian stimulation with no CHC break versus ovarian stimulation after a CHC break. AFC was measured serially in the BREAK group. We assessed whether AFC suppression was reversed in the BREAK group. Total oocyte yield was compared among the NO CHC, BREAK, and NO BREAK groups. T tests, ANOVA, and linear/logistic regressions were used. Seven hundred forty-three women underwent FP. Twenty-one percent (n = 154) were taking long-term CHC (≥6 months). AFC suppression was more likely with CHC use (OR 1.6, 95% CI 1.1–2.4, P = 0.011). The BREAK group (n = 79) stopped CHC for an average of 4 months. AFC improvement started at 1 month and plateaued at approximately 6- to 7-month break. The BREAK group had approximately twice as many oocytes per initial AFC as NO BREAK (2.8 ± 3.8 vs. 1.4 ± 0.9, P < 0.001). When women present for FP on CHC, AFC may be suppressed. A CHC break of several months is associated with an increase in AFC and a potential improvement in overall egg yield.
A web-based learning environment to support chemistry

Increasing the use of technology is essential for the vitality of today's classroom because technology creates an environment that fosters positive attitudes toward learning and increase technologically literacy among K-12 students. Web-based applications that are centered on classroom lessons are effective at increasing literacy because it heightens students' motivation and interaction with technology. This paper will address the effect technology can have on advancing computer literacy when incorporated into the classroom through web-based learning environments. Moreover, it will take you behind the scenes from design to implementation of ChemiNet which is a web-based learning environment to support introductory Chemistry.
The effect of pendant alkyl chain length on the barrier properties of epoxy/amine crosslinked networks

Abstract Aliphatic amido amine crosslinkers have been commercially used in epoxy coatings to enhance water barrier properties for corrosion prevention. However, there is only an empirical understanding of how these aliphatic polyamine crosslinkers affect properties of thermoset polymers, which limits our ability to design newer and more environmentally friendly coating systems. In this work, a series of model aliphatic amido amine curing agents are synthesized and used to create model epoxy/amine networks found in commercial coating formulations. These model systems are interrogated to understand the effects of pendant alkyl chain length material properties including modulus, glass transition temperature, solubility, diffusivity, and permeability of water. This work shows that increasing the pendant aliphatic chain reduces the solubility of water while simultaneously increasing the diffusivity to water in the polymer network.
The Impact of the Summer Pre-matriculation Program on Student Approaches to Studying in Gross Anatomy Course

To support early success in medical or dental school, respectively, the University of Mississippi Medical Center (UMMC) offers a six-week pre-matriculation program for academic performance and social adaptation to students accepted despite some variance in their academic records (a lower DAT or MCAT score, grade point average, or other academic gap). These students are offered a preview of first year basic science courses, including biochemistry, histology, and gross anatomy. A 2014 pilot study suggests the program’s benefits, but does not examine student approaches to studying across its challenging curriculum. To investigate whether or not the program currently supports effective study approaches, we examined (1) students’ approaches to studying before and after the six-week summer pre-matriculation program; (2) the relationship between the academic performance and approaches to studying; (3) changing patterns of approaches to studying for high- and low-performing students. Our data showed that 20% of students changed their dominant approach to studying after the summer program, with an overall positive shift towards deep approach to studying. Despite the absence of any significant correlation between academic performance and any type of approach to studying, differential adjustments were noted between high- and low-performing students and further analyzed. Overall, the summer pre-matriculation program fostered a positive shift to the preferred deep approach to studying; however, educators should monitor and mentor individual students, especially the low-performing students, so as to better guide their academic adaptations.

Hungarian Scientists in Information Technology

Studying Information Technology, the History of Science and Technology was very rich in Hungarian talents; those who designed ‘clever’ machines at the very early times of calculators. These calculators are the ancestors of the present-time ones that were called later on, in the 20th century, computers. The computer historians may agree or disagree, but I think the first real-life, early ‘calculator-like’ machine was developed by Farkas Kempelen in the 18th century. It was a real output device, a talking machine. Its input was an organ, a music instrument keyboard and the operator of the machine could enter the text and the output of the operation was a human-like speech.
The Presence of Culture in Learning

The selection of instructional strategies for learners requires consideration of the role of culture in learning. This chapter reviews current research across disciplines (i.e., mathematics, science, and e-learning) to provide a critical analysis of applications and conceptualizations of culture in learning. Given this research, implications for culture-based instructional strategies are offered.
The Competitive Equilibrium: A Qualitative Analysis

In value and Capital, Hicks [1] discussed the comparative statics properties of the competitive equilibrium in two qualitatively specified cases: (i) the case in which all commodities are “gross substitutes,” i.e., an increase in the price of commodity i leads to an increase in excess demand for commodity j (i ≠ j); (ii) the “Morishima” case in which all commodities obey the rules “substitutes of substitutes are substitutes, complements of substitutes and substitutes of complements are complements, and complements of complements are substitutes.” In his comparative statics analysis, Hicks assumed that equilibrium positions of the competitive economy were characterized by Hicksian perfect stability. Following Hicks’ work, Mosak [2] extended certain of the Hicksian propositions concerning the gross substitute case, Metzler [3] proved the equivalence of Hicksian perfect stability and local dynamic stability in the sense of Samuelson [4] for the gross substitute case, and Arrow, Block and Hurwicz [5] established global stability of the competitive equilibrium for this case. McKenzie [6] proved that local stability occurs in the gross substitute case if and only if the coefficient matrix of the system is quasi-dominant diagonal. Arrow and Hurwicz [7], and McKenzie [6] established results similar to those noted above for the gross substitute case for the more general case of indecomposable systems involving weak gross substitutes (an increase in the price of commodity i leads to either an increase or to no change in excess demand for commodity j (i ≠ j)).

A note on the extremal noncentral sections of the cross-polytope.

We find minimal and maximal length of intersections of lines at a fixed distance to the origin with the cross-polytope. We also find maximal volume noncentral sections of the cross-polypote by hyperplanes which are at a fixed large distance to the origin and minimal volume sections by symmetric slabs of a large fixed width. This parallels recent results about noncentral sections of the cube due to Moody, Stone, Zach and Zvavitch.
MECHANISM OF ACTION: AGE DIFFERENCES IN RESPONSE TO ACCEPTANCE AND COMMITMENT THERAPY FOR CHRONIC PAIN

A recent randomized comparison of Acceptance and Commitment Therapy (ACT) vs. Cognitive-Behavioral Therapy for chronic pain found a clear age interaction effect, such that older adults benefitted more from ACT. In a subsequent study comparing ACT delivered in person to ACT delivered via telehealth to a sample of veterans (N=128, mean age 51.9, SD 13.3, range 25-89), we found no significant age by modality interactions, suggesting that older veterans responded as well as younger people did to telehealth delivery. Consistent with our previous findings, we found a trend for older adults to experience greater reduction in pain interference (p = .051) and significantly greater reduction in pain severity (p = .001) than younger adults following ACT. In younger veterans, change in pain acceptance from baseline to posttreatment was related to change in pain interference from baseline to 6-month follow-up (r = -.38), but change in pain interference from baseline to posttreatment was not related to change in pain acceptance from baseline to follow-up (r = .14), suggesting that, consistent with the ACT model, increased pain acceptance at posttreatment was related to reduced pain interference at follow-up. By contrast, in older veterans, both correlations were significant and of comparable magnitude (rs = -.43 and -.46, respectively), providing no support for the idea that change in pain acceptance drove change in pain interference. Overall, our findings suggest that ACT may work better in older adults with chronic pain than in younger adults, but via a different mechanism.
Acordam e sonham uma aproximação polifônica ao romantismo freiriano

A biografia de Paulo Freire serve como uma bussola a sua praxis pedagogica. No presente estudo, excertos dos seus textos e das suas entrevistas constituem um conjunto de textos que sao submetidos a analise para dai se deduzir momentos que foram chave na vida dele. Tambem deduz, neste trabalho, que o filosofo e educador pernambucano pertence a linha nobre dos românticos e que os seus antecessores ideologicos incluem Jean-Jacques Rousseau e William Morris. O modo como Freire trata as questoes humanas o colocam diametralmente na posicao antagonica a qualquer tipo de conservadorismo ou neoconservadorismo.
A Cylinder Deactivation Control Framework for Gasoline Engines without Valve Deactivation

Gasoline engines remain the most dominant power source for light-duty to medium-duty ground vehicles. Improving gasoline engine efficiency is critical for reducing greenhouse gas emissions and fuel consumption. Cylinder deactivation has proved to be an effective measure in improving fuel efficiency. Nevertheless, the market share of cylinder deactivation remains limited, due to lack of costly valve deactivation hardware. This paper presents an alternative control framework which is capable of enabling cylinder deactivation without using the current valve deactivation mechanisms. The new cylinder deactivation control framework mainly consists of closed-loop lambda controllers, a dual-stage adaptive engine speed controller and a two-stage emissions control. Experimental results demonstrated that, in idling condition, the proposed control framework was capable of reducing fuel consumption by up to 25.33%, while maintaining smooth engine speed profile with minimal speed variations. The feasibility of emissions control using a two-stage TWC control is also discussed and validated using experimental data.
Fast Solar System transportation with electric propulsion powered by directed energy

Abstract Exploration of the Solar System is constrained by interplanetary transfer technology. Current propulsion architectures do not allow for trajectories much faster than Hohmann transfers, implying elevated health risks and mission costs associated with multi-year human spaceflight missions and even longer robotic mission times. Proposed advanced nuclear and exotic systems involve immature component technologies and high degrees of complexity, cost, and risk. Breakthrough improvements may be possible with electric propulsion powered by directed energy, where a large-aperture laser phased array directs energy to photovoltaics on electric propulsion vehicles. Narrowband intensity gain over sunlight would lower onboard power system specific mass (kg/kW) to enable fast Solar System missions without advanced nuclear or exotic power and propulsion systems. The proposed architecture is modular and offers scalability from nanosatellites to human missions, with opportunities for operational systems and Solar System exploration along a technology development roadmap.
Eigenvectors from eigenvalues: the case of one-dimensional Schrödinger operators

We revisit an archive submission by Denton et al. (Eigenvectors from eigenvalues: a survey of a basic identity in linear algebra. arXiv:1908.03795v3 [math.RA], 2019) on $$n \times n$$ self-adjoint matrices from the point of view of self-adjoint Dirichlet Schrodinger operators on a compact interval.
Mental Health Implications of Same-Sex Marriage: Influences of Sexual Orientation and Relationship Status in Canada and the United States

SUMMARY Marriage is a mental health protective factor and homosexuality is sometimes a risk factor. The combined effect of these factors on mental health was examined in this study. We conducted a secondary analysis of an international, cross-sectional survey completed in 2000 (N = 7,616). We examined risks of suicide ideations and attempts, behavioral problems, and treatment histories for male and female participants from Canada and the United States. We found significant relations between sexual orientation and suicidality in all four gender-country groups. We found significant associations between relationship status and suicidality for men but not women in both countries. Behavioral problems and treatment histories were equivocal. We discuss the mental health implications of these findings for same-sex marriage.
Experimental Study of Structural Zone Model for Composite Thin Films in Magnetic Recording Media Application

Composite thin films are a new area of study with many applications, e.g. metal + oxide thin films in high density magnetic recording media. Engineering the processing, microstructure and properties of these thin films is of great importance. It has been found that microstructures of the thin films depend strongly on the oxide volume fraction and pressure during sputtering. Surface diffusion and self-shadowing effects are found to play important roles in determining various thin film microstructures under different processing conditions. Four characteristic microstructural zones could be generally distinguished: “percolated type”(A), “maze-like type”(T), “granular columnar type”(B) and “embedded type”- a microstructure with metal nanocrystals embedded in the amorphous matrix (C). This modified structural zone model of composite thin films has been proposed as a supplement to Thornton’s model for sputtered thin film system.
On the Semantics of the Ought-To-Do

Deontic concepts like ought, right, obligation, forbidden, and permissible have benefited from the philosophically exciting work in the semantics of modal concepts done by Kanger1, Hintikka2, Kripke3, Montague4 and others. Their semantics illuminates both the topic and the contribution of the standard axiomatic approach to deontic logic: the topic is what philosophers used to call the Ought-to-be. On the other hand, the nonstandard approach represented by early axiomatic deontic systems of ours deals with the Ought-to-do. Thus, rather than competing with the standard approach to deontic logic, our non-standard approach complements it. This can, however, be seen only by providing our nonstandard approach with a minimum of semantical foundations. This is precisely what this essay attempts to do. We shall also provide a rationale for our non-standard semantical system by formulating some proto-philosophical data that both guide the development of the system and serve as tests of adequacy for it. In fact, our concern is primarily philosophical, not technical.
An algebraic setting for belief functions

We detail a specific algebraic setting for the study of functions from the set of subsets of a finite set into the real numbers, in particular for the study of belief functions.
Female Educational Leadership through an East-West Metaphor: A Journey

Abstract Meeting the global need for educational leaders presents challenges for every school system due to economic, style, role, and cultural differences. Recruiting leaders who can work through the challenges stands as a goal for every school regardless of gender, yet females are underrepresented in educational leadership globally. This article is based on three years of research and interviews with female educational leaders in China and the United States and explores the idea that words and phrases used by female leaders communicate gender identity, intersections between ethnicities, economic levels, and cultural priorities. The word that arose most often in the interview responses from 35 female educational leaders, and that was used metaphorically by female educational leaders from remote rural areas of China to the New York City metropolitan area, was journey . Keywords : intersections, female, educational leaders, metaphors, journey

Cognitive Impairment in Neurological Diseases: Lessons from Apolipoprotein E

Apolipoprotein E4 (ApoE4) has been considered to have detrimental effects on the age of onset and progression in Alzheimer's disease. Evidence continues to accumulate regarding the effects of ApoE isoforms in a number of other neurological diseases. Recent studies demonstrate an increase in cognitive deficits in ApoE4 patients with traumatic brain injury, cerebrovascular disease, and delirium. Evidence of the role ApoE isoforms played in cognition in multiple sclerosis has illuminated the neurodegenerative aspects of this disease. It further provides evidence of the effect neuroinflammation has in increasing susceptibility to cognitive decline in younger patients. Determining where these diverse diseases intersect and diverge in their relationship to ApoE provides insight into the two-hit mechanism in cognitive decline.
