On the complexity of purely complex /spl mu/ computation and related problems in multidimensional systems

In this paper, the following robust control problems are shown to be NP-hard: given a purely complex uncertainty structure /spl Delta/, determine if: 1) /spl mu//sub /spl Delta//(M)<1, for a given rational matrix M; 2) /spl par/M(/spl middot/)/spl par//sub /spl mu//<1, for a given rational transfer matrix M(s); and 3) inf(Q/spl isin/H/sup /spl infin//)/spl par/F(T,Q)/spl par//sub /spl mu//<1, for a given linear fractional transformation F(T,Q) with rational coefficients. In other words, purely complex /spl mu/ computation, analysis, and synthesis problems are NP-hard. It is also shown that checking stability and computing the H/sup /spl infin// norm of a multidimensional system, are NP-hard problems. Therefore, it is rather unlikely to find nonconservative polynomial time algorithms for solving the problems in complete generality.
Interpretation of uniform translational image motion: DCT versus FT

We study properties of the discrete cosine transform (DCT) when applied to an image sequence formed by uniformly translating a still image. The Fourier transform (FT) applied to such a sequence has non-zero content only on a spatio-temporal frequency plane orthogonal to the direction of motion. We derive an equivalent spectrum for the DCT case. The spectrum function is more complicated than in the FT case and cannot be easily interpreted analytically. However, its numerical evaluation demonstrates that spectral occupancy in the DCT domain is limited to a narrow band around a plane similar to one in the FT case with two important differences: the plane is subject to folding, and the DCT coefficient amplitude is strongly attenuated for larger temporal "frequencies". We verify the theoretical derivations experimentally on images. The obtained result opens an interesting possibility for the computation of constant-velocity motion in the DCT domain. We demonstrate some preliminary results of motion estimation in the 3D DCT domain by identifying directions of spectral occupancy with respect to transform coefficients.
Hysteresis in transfer characteristics in 4H-SiC depletion/accumulation-mode MOSFETs

Hysteresis in room-temperature transfer characteristics between forward (pinch-off voltage, V/sub P/=-15 V) and reverse gate voltage sweeps (V/sub P/=7 V) in n-channel depletion/accumulation-mode 4H-SiC MOSFETs is reported. Transfer characteristics exhibit a parallel shift toward negative voltages depending,on the starting gate voltage and direction of the sweep. The hysteresis and shift in transfer characteristics are related to changes in effective fixed-oxide charge resulting from changes in interface trap occupancy. Interface trap occupancy changes depending on the magnitude of the starting gate voltage and the direction of gate-voltage sweep. At high temperatures, the hysteresis between forward and reverse gate voltage sweep decreases.
Human Monocyte Subsets at Homeostasis and Their Perturbation in Numbers and Function in Filarial Infection

To characterize the function and plasticity of the major human circulating monocyte populations and to explore their role in systemic helminth infection, highly purified (by flow-based sorting) human monocyte subsets (CD14(hi)/CD16(neg) [classical], CD14(+ or hi)/CD16(med) [intermediate], and CD14(neg)/CD16(hi) [nonclassical]) were examined at homeostasis and after activation. Among these three subsets the classical and intermediate subsets were found to be the major sources of inflammatory and regulatory cytokines, as well as cytokines/chemokines associated with alternative activation, whereas the nonclassical and classical populations demonstrated an ability to transmigrate through endothelial monolayers. Moreover, it was primarily the classical subset that was the most efficient in promoting autologous T cell proliferation. The distribution of these subsets changed in the context of a systemic helminth (Wuchereria bancrofti) infection such that patent infection altered the frequency and distribution of these monocyte subsets with the nonclassical monocytes being expanded (almost 2-fold) in filarial infection. To understand further the filarial/monocyte interface, in vitro modeling demonstrated that the classical subset internalized filarial antigens more efficiently than the other two subsets but that the parasite-driven regulatory cytokine interleukin-10 was exclusively coming from the intermediate subset. Our data suggest that monocyte subsets have a differential function at homeostasis and in response to helminth parasites.
Automated liver elasticity calculation for MR elastography

PURPOSE MR elastography (MRE) is a phase-contrast MRI technique that is used to quantitatively assess liver stiffness for staging hepatic fibrosis. The current approach requires manual selection of a region of interest (ROI) with good wave quality from which to measure stiffness. The purpose of this work was to develop and evaluate a fully automated approach for measuring hepatic stiffness from MRE images to further reduce measurement variability. MATERIALS AND METHODS An automated liver elasticity calculation (ALEC) algorithm was developed to address reader stiffness measurement variability. ALEC has three stages: initial tissue estimation, segmentation, and ROI cleanup. Stiffnesses measured by the algorithm were compared with technicians and an expert radiologist in a set of 121 clinical cases acquired at 1.5 Tesla. Intra-class correlation (ICC), Bland-Altman analysis, and a noninferiority test were performed to evaluate whether the algorithm can be used in place of manual analysis by technicians. RESULTS The stiffness measurement difference with the expert was 1.42% ± 11.17% (mean ± standard deviation) for the algorithm and 1.82% ± 13.65% for the technicians. The ICCs were 0.981 and 0.984, respectively. Both the algorithm and technicians were equivalent to the expert within a 5% significance margin (P < 0.01). The algorithm had no failures in the 119 cases that were considered analyzable by the human readers. CONCLUSION The results of this study show that the newly developed automated algorithm is able to measure stiffness in clinical liver MRE exams with an accuracy that is equivalent to that of an expert radiologist. ALEC may be useful for analysis of archived data and suitable for performing multi-center studies.
The time-series relations among expected return, risk, and book-to-market ☆

This paper examines the time-series relations among expected return, risk, and bookto-market (B/M) at the portfolio level. I "nd that B/M predicts economically and statistically signi"cant time-variation in expected stock returns. Further, B/M is strongly associated with changes in risk, as measured by the Fama and French (1993) (Journal of Financial Economics, 33, 3}56) three-factor model. After controlling for risk, B/M provides no incremental information about expected returns. The evidence suggests that the three-factor model explains time-varying expected returns better than a characteristics-based model. ( 1999 Elsevier Science S.A. All rights reserved.

On the influence of Coriolis force on onset of thermal convection

The effect of Coriolis force on the onset of thermal convection in a shallow layer of viscous liquid is studied in the limit of rapid rotation of the layer. Existing results which apply when the fluid lies between free boundaries are extended to the case where the boundaries are rigid.
FIELD EVALUATION OF A STORMWATER BIORETENTION FILTRATION SYSTEM

A field evaluation of the Filterra ® Stormwater Bioretention Filtration System was performed to: 1) determine removal efficiency information based on field data, which is inherently more variable than laboratory data, and 2) compare the observed field efficiency with the efficiency determined in the laboratory. Inlet and outlet pollutant concentrations from a Standard 6’ × 6’ Filterra ® System (manufactured by the Filterra Division of Americast, Inc.) were monitored between October 19, 2004 and November 22, 2005. The pollutants of interest were total suspended solids (TSS), total phosphorus (TP), total Kjeldahl nitrogen (TKN), and the heavy metals cadmium, copper, lead and zinc. Monitoring data were then evaluated to determine appropriate efficiency ratios. Raw data were first evaluated to determine if they were normally distributed. If so, the efficiency ratio was determined based on the event mean concentrations (EMCs) of the influent and effluent samples. If the raw data were not normally distributed, the efficiency ratio was calculated using the EMCs. Results show the following average efficiency ratios: TSS 85%; TP 55%; TKN 20%; Cu 16%, and Zn 50%. Statistical significance and seasonal variations of the removal efficiency were also examined.

The Israel Lobby: Creating an Engine of Geopolitics

The Israel Lobby is a euphemism for a powerful engine of geopolitics: it is a global conglomerate of national and international Jewish organizations that have drawn upon the intellectual, financial and organizational resources of the Jewish diaspora as well as that of their host societies. Starting in the late 19th century, the Israel Lobby pursued two tasks. It had to persuade the Western Jewry to support the creation of a Jewish state in Palestine. Since Jews alone could not do this, the Lobby also had to recruit the support of major Western powers. Once Israel was created, the Lobby had to use the resources of Israeli Jews, the Jewish diaspora and the Western powers to quickly develop Israel into the unrivaled military power in the region. This essay will examine how the Jewish lobby acquired the resources and power to achieve these goals.
Towards Capturing the Silent Emotional Experience within Healthcare Design

Objective:The aim of this exploration was to develop a technique of capturing the inner emotional experience and private conversations existing within architectural design of two healthcare facilities through the art of poetry. Can this unique emotional journey within healthcare be captured? Background: Healthcare design has begun focusing on user environment and satisfaction. This shift draws attention to healthcare’s interiority, the spirit of a place, and its ability to create individual’s emotional experiences. This paper recognizes design as an art and language. Several studies show that healthcare facility design and created spaces affect patient wellness and their support system. Methods: A checklist was created and used as a tool in a sensual exploration of listening to healthcare interiors, the emotional experience, and the silent conversation. The checklist was applied during a two day listening observation of public spaces at two hospitals in Indianapolis, Indiana University Health and St. Vincent Hospital and Health Center. On the last day,all observations were compiled into narrative poems for each of the spaces. Results: Using the checklist allowed the emotional experiences within the hospitals to be captured during the observations. The narrative poems provided an avenue to capture and encompass healthcare’s interiority. Conclusion: This study confirmed that art can be used as a tool to listen and capture the spirit, aesthetics, and emotions created within healthcare facilities.Capturing one art with another can be incorporated into the design process to ensure designers are creating emotional experiences in healthcare that aid in user wellness.
Internal mammary artery conduit re-use in coronary artery bypass grafting: Case series and review

Left internal mammary artery (LIMA) conduit is the gold standard graft for coronary artery bypass. Due to excellent patency rates with this graft it can safely be used in re-operative coronary bypass surgery. The safety of this technique is demonstrated with our report of re-used LIMA conduits in patients with extensive coronary artery disease (CAD). The success of this technique was evaluated by postoperative computerized tomographic angiography which demonstrated patent conduits and flow to the left anterior descending artery (LAD).
Deformation behavior of Mg single crystals compressed along c-axis

Pyramidal I slip ({10–11} ) was observed to be the dominant slip mode in magnesium single crystals compressed quasi-statically along c-axis at room temperature. Transmission electron microscopy (TEM) observations revealed the dislocation character and structure: some dislocations are long, straight and aligned with the basal plane, while others are curved and are not contained within the basal plane.
Sound Production and Air Entrainment by Breaking Waves: A Review of Recent Laboratory Experiments

We review a series of laboratory experiments on the sound production and air entrainment by breaking waves. The acoustic radiation and microwave backscatter from individual breaking events are found to correlate with the important kinematic and dynamic properties of the breaking waves. Air entrainment measurements show that the bubble plume characteristics evolve as simple functions of time. A large fraction (30% to 50%) of the surface wave energy dissipated is found to be expended in entraining air against buoyancy forces.
How Should Colleagues Respond to Diminishing Capacities of an Aging Surgeon

Quantifying the sensitivity of the network structure and properties from simultaneous measurements during photopolymerization

We present a method that combines experimental and computational approaches to assess a comprehensive set of structural and functional evolution during a network formation process via photopolymerization. Our work uses the simultaneous measurement of the degree of conversion, polymerization stress, the change in reaction temperature, and shrinkage strain in situ. These measurements are combined with the theory of viscoelastic materials to deduce the relaxation time and frequency-dependent modulus of the polymerizing network. The relaxation time and degree of conversion are used to demonstrate the effect of processing parameters (e.g. curing protocol adjusted by the light intensity) in creating different network structures for the same initial resin. We describe experimental trends using effective medium calculations on a cross-linked polymer network model. In particular, we show that the effect of curing conditions on the spatial heterogeneity in crosslink density can be quantified using multiparametric measurements and modeling. Collectively, the present method is a way to examine holistically the complex structural and functional evolution of the network formation process.

THE TRANS-SIBERIAN LANDBRIDGE, A NEW TRADE ROUTE BETWEEN JAPAN AND EUROPE: ISSUES AND PROSPECTS

Since 1971, an increasing share of freight traffic between Japan and Europe has been moving in container shipments over the Trans-Siberian Railroad, which offers lower costs than the all-water route and roughly the same transit time. In the last six years, the overland route has managed to capture 25 percent of the Japan-to-Europe trade in container cargo, with about one million tons of freight traveling this route a year. The Siberian overland route has thus become a bonus for producers, shippers and consumers, and a revenue earner for the Soviet Union, but also a threat to shipowners engaged in the competing all-water route. A specialist in international business examines the origins of this new international transport route, its physical requirements (container terminals, container inventory, specialized flat cars, etc.) and prospects for expansion (the Baykal-Amur Mainline), the need for balancing eastbound and the now predominant westbound flows, and the impact on shipping lines. (The Pacific Rim Pro...
Treatment With Chemotherapy and Cognitive Functioning in Older Adult Cancer Survivors

Abstract Objective To investigate whether treatment of cancer with chemotherapy, as compared with surgery and radiation, differentially affects cognitive functioning in older adults. Design Latent class growth analysis approach. Setting Health and Retirement Study. Participants Older adults (N=403) with a new diagnosis of cancer who were still alive 4 years after their diagnosis. Interventions Not applicable. Main Outcome Measures Cognition (degree of immediate recall and delayed recall of a word list). Results Findings indicated that 3 classes of cognitive functioning best fit the data, specifically high, middle, and low recall classes. Individuals treated with chemotherapy were significantly more likely to be in the high recall class, with no effect of receiving surgery or radiation. When interactions with demographic predictors were entered into the model, an Age × Treatment interaction was present such that individuals younger than 80 years were more likely to both receive chemotherapy and have high recall cognition. Conclusions Three distinct classes of cognitive functioning emerged in older adults with cancer. Treatment with chemotherapy predicted likely membership in the high recall class in this sample of cancer survivors; however, this was due to an Age × Treatment interaction. Implications for understanding cognitive sequelae of cancer in late life are discussed.

Mysteries regarding the surgically reattached retina.

Purpose To present contemporary information regarding the continued inability to reliably predict visual acuity following successful retinal reattachment surgery. Methods Literature review. Results Anatomical results of surgery for retinal detachment continue to be far superior to visual results. Clinical factors that have been considered important in predicting postoperative visual acuity include preoperative vision, duration of detachment, height of detachment, and preoperative potential acuity meter results. Recently, optical coherence tomography (OCT) studies have been employed for the purpose of predicting postoperative visual acuity, but to date none of these devices can precisely forecast postoperative vision in an individual eye. Conclusions Preoperative visual acuities appear to be the most important clinical variants correlating with postoperative visual results. Although advanced OCT techniques have identified preoperative and postoperative anatomical alterations that correlate with preoperative and postoperative visions in groups of eyes, no single specific finding indicates unequivocal visual success, and most reports continue to include examples of exceptions to statistical trends.
Constitutionalism and Pluralism in Marbury and Van Gend

The European Court of Justice's landmark decision in Van Gend en Loos is often casually compared to Marbury v. Madison simply because in each case a central high court declares itself to be the final arbiter of central government law. But there is a good deal more to the comparison than this. Both cases serve up what is perhaps the single most profound and complex issue in their respective constitutional systems: multiple competing claims of ultimate legal authority. In addressing this issue, both decisions make important claims for central judicial authority. And yet, neither decision successfully establishes a central judicial monopoly over final legal authority. Instead, both decisions inaugurate a tradition of mutual accommodation among the competing actors lasting to this very day. By juxtaposing accommodation in the two systems, we may understand these practices better than if we limit ourselves to only one or the other legal order. In particular, we recognize that actors in both systems rely on considerations of voice, expertise, and rights to manage the pluralist standoff.
A system to enable relational persistence and semantic web style access simultaneously for objects

Object Oriented (OO) programming is dominant in the current software development. Starting from the design of OO models for applications, developers also expect to address issues on the data of models and the semantics of models. Objects, being the data of models, could be stored in relational databases, and ontologies appear as a good candidate for capturing the semantics of models. This poster presents a method and system which elegantly generates relational schema, OWL ontology, and semantic mapping between them, for any given OO model. The resulting relational schema serves for storing objects that are defined in the input OO model, the resulting OWL ontology is assured by a semantically "close" model transformation, and the generated automation mapping between them enables relational persistence and Semantic Web style access simultaneously for objects.

Advancing Oral Health Knowledge and Attitudes of Physician Assistant Students Using the Smiles for Life Oral Health Curriculum

Background and objectives The purpose of this study was to determine the effectiveness of the Society of Teachers of Family Medicine's Smiles for Life: A National Oral Health Curriculum on the knowledge and attitudes of physician assistant students regarding oral health. Methods Seventy-two didactic year physician assistant students from one physician assistant program were surveyed to assess their knowledge and attitudes regarding oral health prior to starting the Smiles for Life oral health curriculum. The students were electronically surveyed a second time 1 week after completing all online modules in the Smiles for Life oral health curriculum. Results Precourse and postcourse survey response rates were 57% and 36%, respectively. The mean of the attitude statements increased from 3.20 on the precourse survey to 3.87 on the postcourse survey (P=.0012). The mean number of correct responses on the knowledge questions increased from 6.83 on the precourse survey to 9.85 on the postcourse survey (Pl.0001). Conclusions Statistically significant improvements in the attitudes toward oral health and oral health knowledge of physician assistant students after completion of the Smiles for Life curriculum were observed. This study illustrates the effectiveness of the Smiles for Life curriculum as an interprofessional educational experience. This curriculum can be completed online and does not require faculty expertise in oral health, thus removing previously cited barriers to incorporating oral health into the physician assistant curriculum.
Review: The Log Cabin: An American Icon, by Alison K. Hoagland

Alison K. Hoagland The Log Cabin: An American Icon Charlottesville: University of Virginia Press, 2017, 292 pp., 16 color and 120 b/w illus. $29.50 (paper), ISBN 9780813942575 No American who has been to a summer camp, a national park, or Disneyland is without memories of log cabins. As Alison K. Hoagland enthusiastically points out in her new book on a familiar topic, Americans from Davy Crockett to Laura Ingalls Wilder have extolled the virtues of buildings made of logs freshly cut from the forest, constructed by hardy pioneers. Hoagland is well qualified to write about these buildings, having done stints as a National Park Service historian, professor of architectural history, and preservationist. Her 1993 book Buildings of Alaska , part of Oxford University Press's Buildings of the United States series, is full of examples of log cabins, some of which also appear in her current monograph. A number of the excellent photographs presented in The Log Cabin are her own, taken on trips all over the United States, during which she also collected postcards showing cabins as objects of popular culture. Like a good detective, Hoagland analyzes evidence from well-trodden sources as well as new discoveries, weaving it into a fresh and invigorating study that will serve as a definitive resource for some time to come. Her chapters treat everything from slave quarters to contemporary log homes in succinct, no-nonsense prose. She even includes two helpful sections on sources and historiography. Hoagland begins by examining folk images and stories from the nineteenth century that introduce the log cabin as a distinctly American house type; she then goes on to define the form and the technologies that various ethnic groups used to construct their buildings. She carefully considers the controversy over the origins of log construction in the New World, noting early examples of structures made by Swedes and Germans along the Eastern Seaboard but also discussing the log-building traditions among Native Americans, explorers on the western frontier, …

Toward Expedited Impedance Tuning of a Robotic Prosthesis for Personalized Gait Assistance by Reinforcement Learning Control

Personalizing medical devices such as lower limb wearable robots is challenging. While the initial feasibility of automating the process of knee prosthesis control parameter tuning has been demonstrated in a principled way, the next critical issue is to improve tuning efficiency and speed it up for the human user, in clinic settings, while maintaining human safety. We, therefore, propose a policy iteration with constraint embedded (PICE) method as an innovative solution to the problem under the framework of reinforcement learning. Central to PICE is the use of a projected Bellman equation with a constraint of assuring positive semidefiniteness of performance values during policy evaluation. Additionally, we developed both online and offline PICE implementations that provide additional flexibility for the designer to fully utilize measurement data, either from on-policy or off-policy, to further improve PICE tuning efficiency. Our human subject testing showed that the PICE provided effective policies with significantly reduced tuning time. For the first time, we also experimentally evaluated and demonstrated the robustness of the deployed policies by applying them to different tasks and users. Putting it together, our new way of problem solving has been effective as PICE has demonstrated its potential toward truly automating the process of control parameter tuning for robotic knee prosthesis users.
Psychotherapy With Cardiac Patients: Behavioral Cardiology in Practice

Heart disease is the leading cause of the death in the United States, and those who experience cardiac events suffer a wide range of psychological sequelae. Yet, few books show psychotherapy practitioners how they can modify their techniques to accommodate the unique needs of this population. The author, an experienced hospital-based psychologist, provides an orientation to this specialization and, drawing on a variety of therapy models, describes empirically-supported intervention strategies. After providing an overview of the cardiovascular system, she discusses lifestyle and psychological risk factors for heart disease. Subsequent chapters cover practical techniques for helping patients overcome depression, anxiety, and hostility, all facotrs that complicate recovery. A final group of chapters addresses factors that affect treatment effectiveness, such as substance abuse problems, overweight, and sex differences. Case illustrations are provided throughout.
Integrated older people care and advanced practice nursing: an evidence-based review

Aim To critically appraise and synthesize evidence of integrated care stemming from advanced practice nursing in elderly primary care settings throughout the United States and Thailand. Background Advanced practice nurses are key to accelerating integrated elderly care in the community. Yet, their scope and capacity vary greatly across countries, making impact measurement highly challenging. Methods A systematic search of PubMed, CINAHL, Scopus and ThaiJo databases was performed. Full-text articles in English or Thai language were reviewed using an inductive thematic approach from the integrated people-centred Health Services framework, adopted by the World Health Organization. Results A total of 42 articles were appraised according to framework strategies: (1) people and community empowerment/engagement; (2) governance and accountability strengthening; (3) model of care reorientation; (4) service coordination; and (5) enabling environment creation. Collaborative roles and empowerment of older people were associated with higher quality of care. Thai nurses empowered individuals through community networks and resources, incorporating care models (strategy 1). In contrast, US nurses adopted a quality improvement and safety approach, incorporating technology into nursing interventions (strategy 5). Conclusion Advanced practice nurses employ an array of strategies and approaches in caring for older people. Although their role varies from mostly substitute (US) to supplemental (Thailand), nurses in both countries contribute towards integrated person-centred care. Implication for nursing practice and nursing policy Preparing advanced practice nurses to work in the community is a prerequisite for meeting ageing population health needs in a sustainable manner. Education, professional development and leadership training opportunities should focus on capacity building in: a) strengthening mutual accountability, b) reorienting the work environment through innovative care models and c) coordinating services through partnerships to achieve universal health and ensure healthy ageing.
Existence of k-People Stable Alliance in n-Player Cooperative Games

This paper considers the existence of a stable k-cooperative alliance with a nonempty core in an n-person cooperative game on the premise that the Nash negotiation solution is the distribution criterion. First, the situation of a two-person alliance is examined, and the concept of stable two-person alliance is given and further proves that there must be a stable two-person alliance in n-person cooperative games. Then, analyze the stable k-man alliance and give a sufficient condition for the existence of a stable k-person alliance. Further, an algorithm is designed to find a match equivalent to the existence of a stable k-league alliance. In addition, this article also provides sufficient conditions for the benefits of all players in a k-man alliance to lie in its internal suballiance. Finally, an example is given to verify the feasibility of the theory and method in this paper.

Simulation of the Effect of False Data Injection Attacks on SCADA using PSCAD/EMTDC

Transient simulation is a critical task of validating the dynamic model of the power grid. We propose an off-line method for validating dynamic grid models and assessing the dynamic security of the grid in the presence of cyberattacks. Simulations are executed in PowerWorld and PSCAD/EMTDC to compare the impact on the grid of cyber-attacks. Generators in the IEEE 14-bus system have been modified to match the need of adjustment in modern power system operation. To get effective measurements for state estimation, SCADA polling model is reproduced in PSCAD/EMTDC by providing controlled sampling frequency. The results of a tripped line case and injecting false data to the loads caused by cyberattacks is presented and analyzed.
NYenviroScreen: An open-source data driven method for identifying potential environmental justice communities in New York State

Abstract In 2003, the New York State Department of Environmental Conservation began designating Potential Environmental Justice Areas (PEJA) for the purpose of providing public participation opportunities to disadvantaged communities during permitting deliberations. We developed NYenviroScreen to help stakeholders understand, review, and provide input for how future PEJA designation might be updated and improved, including for identifying disadvantaged communities under the newly enacted Climate Leadership and Community Protection Act (CLCPA). We present and compare three potential update methods and provide an interactive web application for investigating model components and composition. The three methods are: (i) three factor clustering using the Jenks natural breaks algorithm, (ii) a cumulative impact model adapted from CalEPA’s CalEnviroScreen, and (iii) a hybrid approach that uses both methods and incorporates Federal and State recognized tribal land areas. NYenviroScreen brings together federal and state data sources related to population health, sociodemographics, environmental risk factors, and potential pollution exposures for 15,463 census block groups. We find that a hybrid approach provides the most robust coverage for both rural and urban areas of New York State. This publicly accessible innovative approach is an important, data driven effort toward the pursuit of environmental justice in New York State.
Bottomonium suppression and flow in heavy-ion collisions

The strong suppression of bottomonia production in ultra-relativistic heavy-ion collisions is a smoking gun for the creation of a deconfined quark-gluon plasma (QGP). In this proceedings contribution, I review recent work that aims to provide a more comprehensive and systematic understanding of bottomonium dynamics in the QGP through the use of pNRQCD and an open quantum systems approach. This approach allows one to evolve the heavy-quarkonium reduced density matrix, taking into account non-unitary effective Hamiltonian evolution of the wave-function and quantum jumps between different angular momentum and color states. In the case of a strong coupled QGP in which E << T,m_D << 1/a_0, the corresponding evolution equation is Markovian and can therefore be mapped to a Lindblad evolution equation. To solve the resulting Lindblad equation, we make use of a stochastic unraveling called the quantum trajectories algorithm and couple the non-abelian quantum evolution to a realistic 3+1D viscous hydrodynamical background. Using a large number of Monte-Carlo sampled bottomonium trajectories, we make predictions for bottomonium R_AA and elliptic flow as a function of centrality and transverse momentum and compare to data collected by the ALICE, ATLAS, and CMS collaborations.
Examining the influence of social ecological factors on prostate cancer screening in urban African-American men.

African-American men experience a disparate burden of prostate cancer (PC). Little is known about how social factors influence PC screening in this population. Methods: African-American men over the age of 18 (N = 229) were recruited from a community health fair and anonymously surveyed about their PC screening behavior and conditions of their social environment. Analysis included logistic regression. Findings: Fifty one percent of respondents reported receiving any form of PC screening within the past five years. Older age, higher levels of education, and access to a usual health care provider were associated with PC screening. Conclusions: Social workers in preventive and community health settings should be increasingly attentive to the PC screening barriers facing African-American men, particularly those who may be undereducated and lack access to care.
A nursing course with the great masters.

TODAY'S COMPLEX AND DYNAMIC health care landscape requires inquisitive and self-reflective nurse professionals who identify and acknowledge patterns of human experience. In working toward this goal in undergraduate nursing education, faculty must move the curriculum beyond the science of nursing care into the art of nursing. With a focus on the integration of arts and humanities into nursing education, nurse educators will increase selfreflective practices among their students and augment their ability to think critically as competent and caring nurses. While empirical evidence of how the study of art increases analytical critical thinking skills is lacking, the role of the humanities has been discussed in numerous nursing publications (1-4). Their benefits have been hailed as a driving force in the development of communication skills and the encouragement of distinctive interpretations of life situations in a sociocultural and historical context (1,2). The use of aesthetic intervention is prominent in the nursing literature, and the active participation of students in artistic media has been explored as a means for developing creativity and enhancing meaning for students about their role as nurse in the current health care system (5,6). Other benefits, such as the illumination of personal values and morality, an increase in decisionmaking abilities, a respect for the intuitive thought process, and the fostering of curiosity and intellectual inquiry, have been cited as well (1). An upper-division elective, Art in Nursing, was developed to enhance critical thinking by engaging undergraduate nursing students in the world of art. This course involves the integrative and creative process of critique, inquiry, and the creation of artistic endeavors, allowing students to derive themes, make inferences, and participate in the creative, intuitive process of aesthetic knowing. Emphasis is placed on the study and application of art forms as they relate to nursing care. The six cognitive skills of critical thinking developed by the American Philosophical Association's Delphi Study (7) - interpretation, analysis, evaluation, inference, explanation, and self-regulation - are the cornerstone of the course objectives and are built into assignments and evaluation techniques. They epitomize the philosophy of the course, which is to nurture and enrich the creative, perceptive, and critical thought processes of the students by engagement in the world of art. Upon completion of the course, students are expected to meet the following competencies: * Identify, examine, and interpret themes that emerge from visual and linguistic art forms * Analyze derived art themes for an historical perspective and relatedness to the nursing profession * Evaluate art forms from the perspective of the professional nurse * Make logical inferences based on perceptions of visual art forms * Explain visual and linguistic art forms as they relate to the nursing perspective and society at large * Engage in the process of art creation as a self-regulative, unifying experience. …
A mathematical model for the onset of avascular tumor growth in response to the loss of p53 function

We present a mathematical model for the formation of an avascular tumor based on the loss by gene mutation of the tumor suppressor function of p53. The wild type p53 protein regulates apoptosis, cell expression of growth factor and matrix metalloproteinase, which are regulatory functions that many mutant p53 proteins do not possess. The focus is on a description of cell movement as the transport of cell population density rather than as the movement of individual cells. In contrast to earlier works on solid tumor growth, a model is proposed for the initiation of tumor growth. The central idea, taken from the mathematical theory of dynamical systems, is to view the loss of p53 function in a few cells as a small instability in a rest state for an appropriate system of differential equations describing cell movement. This instability is shown (numerically) to lead to a second, spatially inhomogeneous, solution that can be thought of as a solid tumor whose growth is nutrient diffusion limited. In this formulation, one is led to a system of nine partial differential equations. We show computationally that there can be tumor states that coexist with benign states and that are highly unstable in the sense that a slight increase in tumor size results in the tumor occupying the sample region while a slight decrease in tumor size results in its ultimate disappearance.
Religious freedom and gender equality in India

After India gained independence in 1947, the country's leaders promised its diverse constituents citizenship rights that extended across religion, gender, and caste. Distinct from its previous British rule, India's constitutional law guarantees citizens the right to religious freedom and associated cultural practices, and prohibits gender and caste-based discrimination. However, in ensuring freedom of religion, the constitution also effectively affirms gender inequality through patriarchal religious and cultural practices. This article examines how the constitutional rights of religious freedom and gender equality have been negotiated among each other in contemporary Indian society. I draw upon three landmark Indian Supreme Court cases that navigate the terrain of affirming both women's civic rights and religious freedom. Findings suggest that the Supreme Court is working toward a more inclusive definition of citizenship, particularly one which supports women's civic rights within the context of religious personal law.
Enigmatic MYC Conducts an Unfolding Systems Biology Symphony.

The enigmatic MYC oncogene, which participates broadly in cancers, revealed itself recently as the maestro of an unfolding symphony of cell growth, proliferation, death, and metabolism. The study of MYC is arguably most challenging to its students but at the same time exhilarating when MYC reveals its deeply held secrets. It is the excitement of our richer understanding of MYC that is captured in each review of this special issue of Genes & Cancer. Collectively, our deeper understanding of MYC reveals that it is a symphony conductor, controlling a large orchestra of target genes. Although MYC controls many orchestra sections, which are necessary but not sufficient for Myc function, ribosome biogenesis stands out to reveal Myc’s primordial function particularly in fruit flies. Because ribosome biogenesis and the associated translational machinery are bioenergetically demanding, Myc’s other target genes involved in energy metabolism must be coupled with energy demand to ensure that cells can replicate their...
Mice Genetically Depleted of Brain Serotonin Do Not Display a Depression-like Behavioral Phenotype

Reductions in function within the serotonin (5HT) neuronal system have long been proposed as etiological factors in depression. Selective serotonin reuptake inhibitors (SSRIs) are the most common treatment for depression, and their therapeutic effect is generally attributed to their ability to increase the synaptic levels of 5HT. Tryptophan hydroxylase 2 (TPH2) is the initial and rate-limiting enzyme in the biosynthetic pathway of 5HT in the CNS, and losses in its catalytic activity lead to reductions in 5HT production and release. The time differential between the onset of 5HT reuptake inhibition by SSRIs (minutes) and onset of their antidepressant efficacy (weeks to months), when considered with their overall poor therapeutic effectiveness, has cast some doubt on the role of 5HT in depression. Mice lacking the gene for TPH2 are genetically depleted of brain 5HT and were tested for a depression-like behavioral phenotype using a battery of valid tests for affective-like disorders in animals. The behavior ...
Binaural detection with narrowband and wideband reproducible noise maskers. IV. Models using interaural time, level, and envelope differences

The addition of out-of-phase tones to in-phase noises results in dynamic interaural level difference (ILD) and interaural time difference (ITD) cues for the dichotic tone-in-noise detection task. Several models have been used to predict listeners' detection performance based on ILD, ITD, or different combinations of the two cues. The models can be tested using detection performance from an ensemble of reproducible-noise maskers. Previous models cannot predict listeners' detection performance for reproducible-noise maskers without fitting the data. Here, two models were tested for narrowband and wideband reproducible-noise experiments. One model was a linear combination of ILD and ITD that included the generally ignored correlation between the two cues. The other model was based on a newly proposed cue, the slope of the interaural envelope difference (SIED). Predictions from both models explained a significant portion of listeners' performance for detection of a 500-Hz tone in wideband noise. Predictions based on the SIED approached the predictable variance in the wideband condition. The SIED represented a nonlinear combination of ILD and ITD, with the latter cue dominating. Listeners did not use a common strategy (cue) to detect tones in the narrowband condition and may use different single frequencies or different combinations of frequency channels.
Recombinant human protein C, protein S and thrombomodulin as antithrombotics

Over the last 10 years, much has been learned about the human protein C anticoagulation system, a key pathway in maintaining blood in a fluid state in vivo. Three major glycoproteins, namely protein C, protein S and thrombomodulin, are involved in this pathway. The aim of this article is to discuss therapeutic potentials and issues and challenges for developing recombinant protein C, protein S and soluble thrombomodulin as novel antithrombotics. We also briefly discuss other drug design strategies that may be employed in modulating the activity of the protein C anticoagulant pathway under pathological conditions.
Moment tensors of ten witwatersrand mine tremors

Ground motions, recorded both underground and on the surface in two of the South African Gold mining districts, were inverted to determine complete moment tensors for 10 mining-induced tremors in the magnitude range 1.9 to 3.3. The resulting moment tensors fall into two separate categories. Seven of the events involve substantial coseismic volumetric reduction-ΔV together with normal faulting entailing shear deformation ΣAD, where the summation is over fault planes of areaA and average slipD. For these events the ratio-ΔV/ΣAD ranges from 0.58 to 0.92, with an average value of 0.71. For the remaining three events ΔV is not significantly different from zero; these events are largely double-couple sources involving normal faulting. Surprisingly, the two types of source mechanism appear to be very distinct in that there is not a continuous distribution of the source mix from ΔV=0 to-ΔV≈ΣAD. Presumably, the coseismic closure indicates substantial interaction between a mine stope and adjacent shear failure in the surrounding rock, under the influence of an ambient stress for which the maximum principal stress is oriented vertically.
