Parallel Vehicular Traffic Simulation using Reverse Computation-based Optimistic Execution

Vehicular traffic simulations are useful in applications such as emergency management and homeland security planning tools. High speed of traffic simulations translates directly to speed of response and level of resilience in those applications. Here, a parallel traffic simulation approach is presented that is aimed at reducing the time for simulating emergency vehicular traffic scenarios. Three unique aspects of this effort are: (1) exploration of optimistic simulation applied to vehicular traffic simulation (2) addressing reverse computation challenges specific to optimistic vehicular traffic simulation (3) achieving absolute (as opposed to self- relative) speedup with a sequential speed equal to that of a fast, de facto standard sequential simulator for emergency traffic. The design and development of the parallel simulation system is presented, along with a performance study that demonstrates excellent sequential performance as well as parallel performance.
Intimacy Is Sharing Hurt Feelings: A Comparison of Three Conflict Resolution Models

To check on the validity of three different methods of dealing with anger, 1) calm, rational discussion, 2) “fair fighting,” and 3) sharing of hurt and of fear of hurt, two different studies were performed. In the first study a video-taped procedure was presented to 36 undergraduates. Their preferences indicated no support for the hypothesis of sex differences in dealing with conflict and some support to differential preferences for each of three methods. In the second study, three structured programs directly derived from the three theoretical positions were administered at random to 11 couples. Their reactions suggested some support for the position that intimacy may be found in sharing of hurt feelings. Theoretical issues and directions for future research are considered.
High-content screening in zebrafish embryos identifies butafenacil as a potent inducer of anemia.

Using transgenic zebrafish (fli1:egfp) that stably express enhanced green fluorescent protein (eGFP) within vascular endothelial cells, we recently developed and optimized a 384-well high-content screening (HCS) assay that enables us to screen and identify chemicals affecting cardiovascular development and function at non-teratogenic concentrations. Within this assay, automated image acquisition procedures and custom image analysis protocols are used to quantify body length, heart rate, circulation, pericardial area, and intersegmental vessel area within individual live embryos exposed from 5 to 72 hours post-fertilization. After ranking developmental toxicity data generated from the U.S. Environmental Protection Agency's (EPA's) zebrafish teratogenesis assay, we screened 26 of the most acutely toxic chemicals within EPA's ToxCast Phase-I library in concentration-response format (0.05–50 µM) using this HCS assay. Based on this screen, we identified butafenacil as a potent inducer of anemia, as exposure from 0.39 to 3.125 µM butafenacil completely abolished arterial circulation in the absence of effects on all other endpoints evaluated. Butafenacil is an herbicide that inhibits protoporphyrinogen oxidase (PPO) – an enzyme necessary for heme production in vertebrates. Using o-dianisidine staining, we then revealed that severe butafenacil-induced anemia in zebrafish was due to a complete loss of hemoglobin following exposure during early development. Therefore, six additional PPO inhibitors within the ToxCast Phase-I library were screened to determine whether anemia represents a common adverse outcome for these herbicides. Embryonic exposure to only one of these PPO inhibitors – flumioxazin – resulted in a similar phenotype as butafenacil, albeit not as severe as butafenacil. Overall, this study highlights the potential utility of this assay for (1) screening chemicals for cardiovascular toxicity and (2) prioritizing chemicals for future hypothesis-driven and mechanism-focused investigations within zebrafish and mammalian models.
Accelerate video decoding with generic GPU

Most modern computers or game consoles are equipped with powerful yet cost-effective graphics processing units (GPUs) to accelerate graphics operations. Though the graphics engines in these GPUs are specially designed for graphics operations, can we harness their computing power for more general nongraphics operations? The answer is positive. In this paper, we present our study on leveraging the GPUs graphics engine to accelerate the video decoding. Specifically, a video decoding framework that involves both the central processing unit (CPU) and the GPU is proposed. By moving the whole motion compensation feedback loop of the decoder to the GPU, the CPU and GPU have been made to work in parallel in a pipelining fashion. Several techniques are also proposed to overcome the GPUs constraints or to optimize the GPU computation. Initial experimental results show that significant speed-up can be achieved by utilizing the GPU power. We have achieved real-time playback of high definition video on a PC with an Intel Pentium III 667-MHz CPU and an nVidia GeForce3 GPU.
Closed-form blind and semi-blind estimation of linear receivers for space-time coding

This paper exploits a special class of space-time codes in which linearly transformed versions of a given data sequence are transmitted from multiple antennas. Several recently proposed codes, including space-time block codes, are members of this class. The redundancy introduced by the transformations imposes structure on the received data that under certain conditions can be exploited for direct blind (and semi-blind) estimation of a linear zero-forcing receiver that recovers the original data sequence. If the transmitted symbols are constant modulus, the space-time code structure can be exploited by the analytic constant modulus (ACM) algorithm to simplify the separation of multiple co-channel users. If each user employs a different code or only one user is present, the ACM joint diagonalization step can be eliminated even though multiple constant modulus data streams are received.
Electrooptic tunable filters for infrared wavelengths

This paper describes the performance characteristics of an electronically tunable infrared filter based on the electrooptic effect. Like the acoustooptic tunable filter, this device operates by selectively coupling principal polarizations in a birefringent crystal at a Phase-matched wavelength by means of a spatially periodic refractive index perturbation. Instead of a traveling acoustic wave, however, the electrooptic tunable filter employs a temporally static electric field. The main advantages of this filter are its very low power consumption and its versatility of passband programming by virtue of separately addressable voltages under microprocessor control. Two experimental embodiments of the filter are described, one using longitudinal fields, collinear with the light beam, the other using transverse fields in a "thick waveguide" configuration. Experimental results of filter characteristics in the wavelength range 2-10 \mu m are presented. We also present examples of passband synthesis that are achieved by apodizing the amplitude of the applied electric field perturbations. These include passband broadening and sidelobe suppression. The experimental transfer characteristics exhibit good agreement with the theoretical computer plots. Typical driver voltages are ∼ 500 V.
Environmental ranking of amazonian development projects in Brazil

The types of development that now prevail virtually throughout Brazilian Amazonia are transforming vast areas of forest to other ecosystems, a devestation that has become a matter of national controversy. The aim of this paper is to indicate some of the possible environmental costs and benefits of the various choices of development projects. It does not maintain that the forest be totally protected in perpetuity, but that it be approached with the optimal combination of projects over time. Development projects will continue and some will create adverse environmental impacts. This paper seeks to help choose, design, and locate projects in such a way as to minimize these adverse impacts.
A Mixed Finite Element for the Nonlinear Bending Analysis of Laminated Composite Plates Based on FSDT

A mixed finite element model for the nonlinear bending analysis of laminated composite plates is presented. The finite element model is obtained using a mixed variational formulation of the first-order shear deformation theory of plates in which displacements and bending moments are treated as independent fields. A p-type Lagrangian basis is used to approximate the nodal degrees of freedom that consist of three displacements, two rotations, and three moment resultants. The geometric nonlinearity in the sense of the von Karman is included in the plate theory. The mixed plate element developed herein is employed in the linear and nonlinear bending analysis of a variety of layered composite rectangular plates. The effects of transverse shear deformation, material anisotropy, and bending-stretching coupling on deflections and stresses are investigated. The predictive capability of the present model is demonstrated by comparison with analytical, experimental, and numerical solutions available in the literature...
Lesbian Coming Out as a Multidimensional Process

Coming out for lesbians is discussed as a multidimensional process. Four dimensions are presented and explored. First is sexual identity formation which encompasses development of lesbian sexuality and awareness of being a lesbian. Second is disclosure of sexual orientation to others. Third is sexual expression and behavior. Fourth is lesbian consciousness which refers to how lesbians see themselves in relation to the social environment, including lesbian and gay communities. These dimensions are examined in relation to existing theories and research about lesbian coming out processes. Further, there is a discussion of coming out and demographic differences among lesbians. The possible impact of age, race, ethnicity, religion, geographic location, income, employment, and education on lesbian coming out are considered.
Effects of sustained immobilisation on aphids

SUMMARY Immobilisation of aphids of three species, Schizaphis graminum, Myzus persicae and Dactynotus ambrosiae, was accomplished using low temperature (6 ± 1°C; or nitrogen (N2), argon (Ar), or carbon dioxide (CO2) gases at 25°C for 1,3,6, or 24 h. Mortality was recorded and also times until treated aphids first walked or probed. Cold immobilisation caused least mortality and allowed rapid recovery of walking and probing abilities. CO2 treatment, even when accompanied by cyclic administration of bottled air, caused excessive mortality when used beyond 6 h, and long recovery times. After 24 h immobilisation with CO2 aphids seldom walked or probed. N2 or Ar gases, when administered with alternating cycles of bottled air, produced a nontoxic, hypoxic immobilisation from which aphids recovered fairly rapidly to walk and probe, apparently normally.
Etiology and vascularization of dental lamina cysts

I t is believed that dental lamina cysts may arise from unresorbed and enclaved epithelial remnants of the dental lamina. Dental lamina cysts in the maxillary and mandibular dental ridges of the newborn infant may be histologically differentiated fsom enclaved epithelial fragments that may give rise to cysts at points of fusion of the palatomaxillary processes. Cysts derived from unresorbed epithelial fragments of the dental lamina are odontogenic epidermal fissural cysts. It is known that cysts of this class are lined with stratified squamous epithelium, sometimes with dental epithelium, or occasionally with various combinations of these cell types. It might be expected that if the retained epithelial fragments of the dental lamina were nearer to the oral epithelium the future cyst would be lined with stratified squamous epithe1iu.m. If the enclaved fragments were nearer to a developing tooth, however, it might be expected that the future cyst would be lined with a mixture of stratified squamous epithelium and dental epithelium. It could be assumed that, because of the proximity of some enclaved cells of the dental lamina to a developing tooth, at least a few cells might possess some eha,racteristics of hard dental structures. Consequently, upon maturation of the enclaved mass of cells, some histologic features of the enclavement may resemble dentine or enamel, or combinations of the various cell types may give rise to pearllike structures. Cysts situated along the palatal midline are nonodontogenic epidermal fissural cysts that arise from enclaved epithelium at points of fusion where the
Dispersion and alignment of nanorods in cylindrical block copolymer thin films

Although significant progress has been made in controlling the dispersion of spherical nanoparticles in block copolymer thin films, our ability to disperse and control the assembly of anisotropic nanoparticles into well-defined structures is lacking in comparison. Here we use a combination of experiments and field theoretic simulations to examine the assembly of gold nanorods (AuNRs) in a block copolymer. Experimentally, poly(2-vinylpyridine)-grafted AuNRs (P2VP–AuNRs) are incorporated into poly(styrene)-b-poly(2-vinylpyridine) (PS-b-P2VP) thin films with a vertical cylinder morphology. At sufficiently low concentrations, the AuNRs disperse in the block copolymer thin film. For these dispersed AuNR systems, atomic force microscopy combined with sequential ultraviolet ozone etching indicates that the P2VP–AuNRs segregate to the base of the P2VP cylinders. Furthermore, top-down transmission electron microscopy imaging shows that the P2VP–AuNRs mainly lie parallel to the substrate. Our field theoretic simulations indicate that the NRs are strongly attracted to the cylinder base where they can relieve the local stretching of the minority block of the copolymer. These simulations also indicate conditions that will drive AuNRs to adopt a vertical orientation, namely by increasing nanorod length and/or reducing the wetting of the short block towards the substrate.
Psyche—the Meeting of Mind and Soul: Current Psychoanalytic Views on the Mental Representation of God

The author presents an overview of two contemporary, related psychoanalytic perspectives on religious phenomena. Based on data from systematic interviews, Ana-Maria Rizzuto explores the way the human mind forms the idea of God as it evolves through the various stages of childhood and adult development. The object-representation of God is greatly influenced by the mental representations of mother, father, and other important adults in the child’s life. Object relations theory and the writings of Winnicott play an important role in these concepts. William Meissner, a Jesuit priest as well as a psychoanalyst, addresses Freud’s views of religious belief as an illusion, or when accepted with certainty as real, as a delusion. Instead, Meissner sees religious belief as a developmental process that resides in the mental realm of transitional phenomena where spirituality, creativity, appreciation of beauty, transcendental states, play, and the psychoanalytic process itself also take place. In psychoanalytic treatment, religious phenomena are not exempt from exploration and understanding, perhaps resulting in more mature development of object representations, ego functions, and the superego functions of conscience and ego ideal as well as more mature religious life.
Numerical Simulation of Rotating Stall inside High Speed Centrifugal Compressor Using Entire Geometry Mesh

Numerical simulation results of rotating stall flow phenomenon inside a centrifugal compressor with vaneless diffuser by solving three-dimensional Reynolds averaged compressible N-S equations using commercial computational fluid dynamics (CFD) software CFX adopting RNG k-e turbulence model are presented. For exactly simulating the rotating stall at small flow rate, the whole flow field mesh including volute is used. Firstly the steady performance curve is obtained using steady calculations and comparing with experimental results. Secondly, an air chamber model is added at the volute outlet to simulate the rotating stall flow phenomenon inside the centrifugal compressor. The centrifugal compressor internal flow fields at different times during the stall cycle at the small mass flow rate are given to observe the stall flow phenomenon. The air chamber influence on the rotating stall is also investigated. The simulation indicates the more the plenum chamber volume is, the lower the stall frequency will be.
Lightweight Research based on Topology Optimization of the Whole Body

A traditional topology optimization technique mainly focuses on optimization of the location and size of light-weight holes in each individual component,which neglects the optimization of whole body structure and space.In this study,in the conceptual stage of a micro-car development,the overall topology optimization techniques are applied to optimize the whole vehicle body structure considering the overall spatial structure of the body,where vehicle body bending stiffness and torsion stiffness are chosen as the optimization objectives.Then,an optimized spatial skeleton of vehicle body can gain from this process,which afford guidance to the detailed design stage of the body lightweight design.
Budget allocation using weakly coupled, constrained Markov decision processes

We consider the problem of budget (or other resource) allocation in sequential decision problems involving a large number of concurrently running sub-processes, whose only interaction is through their consumption of budget. Our first contribution is the introduction of budgeted MDPs (BMDPs), an MDP model in which policies/values are a function of available budget, (c.f. constrained MDPs which are solved given a fixed budget). BMDPs allow one to explicitly trade off allocated budget and expected value. We show that optimal value functions are concave, non-decreasing in budget, and piecewise-linear in the finite horizon case, and can be computed by dynamic programming (and support ready approximation). Our second contribution is a method that exploits BMDP solutions to allocate budget to a large number of independent BMDPs, coupled only by their common budget pool. The problem can be cast as a multiple-choice knapsack problem, which admits an efficient, optimal greedy algorithm. Empirical results in an online advertising domain confirm the efficacy of our methods.
A computer-managed instruction system applied to dietetic education

The emergence of competency-based programs in dietetic education has introduced the need for a systematic method of managing student performance information. A computer-managed instruction system which performs many of the routine clerical tasks usually assumed by instructors is being utilized in Emory University's Dietetic Internship Program. Preliminary use of the system indicates that it was well received by both instructors and students. Its most obvious benefits were the immediate feedback on performance and decreased demands on faculty time for evaluation and record-keeping processes.
Young organic farmers in Japan: Betting on lifestyle, locality, and livelihood

ABSTRACTThis analysis of Japanese organic farmers in their 30s and 40s gains insight from Lyng’s framework of ‘edgework’—a transgression of life/death boundaries by sports practitioners. Young farmers emerged in qualitative fieldwork as ‘occupational edge-workers,’ crisscrossing binaries such as urban/rural, mind/body, and economic/moral. They manage risks and navigate uncertainties of natural forces, traditional village practices, neoliberal pressures to be entrepreneurial in the market, and judgment of older, purer organic farmers. With goals of living in harmony with nature, intimate others, and community, they create lifestyles in marginal rural localities by which they can make selves that are alternative to the neoliberal narrative, yet act as entrepreneurial subjects that risk bringing their version of morality to the market, via delicious, organic food sold to self-creating consumers. Claiming normality and spurning ideas of organic as a movement, their alterity is partial and practical as they ex...
Chapter 12 - Zebrafish kidney development

The kidney of the zebrafish shares many features with other vertebrate kidneys including the human kidney. Similar cell types and shared developmental and patterning mechanisms make the zebrafish pronephros a valuable model for kidney organogenesis. Here we review recent advances in studies of zebrafish pronephric development and provide experimental protocols to analyze kidney cell types and structures, measure nephron function, live image kidney cells in vivo, and probe mechanisms of kidney regeneration after injury.
Characterization of ${}^{171}Yb^{3+}\!:\! YVO_4$ for photonic quantum technologies

Rare-earth ions in crystals are a proven solid-state platform for quantum technologies in the ensemble regime and attractive for new opportunities at the single-ion level. Among the trivalent rare earths, ^(171)Yb^(3+) is unique in that it possesses a single 4f excited-state manifold and is the only paramagnetic isotope with a nuclear spin of 1/2. In this work, we present measurements of the optical and spin properties of ^(171)Yb^(3+):YVO_4 to assess whether this distinct energy-level structure can be harnessed for quantum interfaces. The material was found to possess large optical absorption compared to other rare-earth-doped crystals owing to the combination of narrow inhomogeneous broadening and a large transition oscillator strength. In moderate magnetic fields, we measure optical linewidths less than 3 kHz and nuclear spin linewidths less than 50 Hz. We characterize the excited-state hyperfine and Zeeman interactions in this system, which enables the engineering of a Λ system and demonstration of all-optical coherent control over the nuclear-spin ensemble. Given these properties, ^(171)Yb^(3+):YVO_4 has significant potential for building quantum interfaces such as ensemble-based memories, microwave-to-optical transducers, and optically addressable single rare-earth-ion spin qubits.
A Pareto Model of Efficiency Dynamics

The Pareto efficiency principle for production systems stipulates that a given firm in an industry is not relatively efficient in producing its outputs from given inputs, if it can be shown that some other firm or combination of firms can produce more of some outputs without producing less of any other output and without utilizing more of any input. This principle has been extended and widely applied in efficiency analysis by what has been called “data envelopment analysis” (DEA) in management science literature. A vast amount of research has been made for DEA models, a good survey for which is available in Cooper et al. (2004) in the framework of operations research. A good economic survey is available in Sengupta (1995, 2003) and Sengupta and Sahoo (2006).
Serbian Spaces of Identity: Narratives of Belonging by the Last Yugo Generation

Yugoslavia may be done, but it lives on in the memory of its last generation, along with the potent mix of nationalisms, globalization, and historical tensions that helped dissolve it. If the dissolution of Yugoslavia has taught us anything, it is that nationalism and globalization are not mutually exclusive. Drawing on the recollections of key figures among the last Serbian generation to grow up Yugoslav, this book explores the transition from socialism to capitalism, from the dream of pan-Slavic working class identity to the contentious capitalist reality that gave us the word “Balkanization”. This book paints the portrait of the ruling generation and its ambivalent attitudes toward both the socialist past and the capitalist, Western-oriented present. In so doing, it also explores the emerging phenomenon of Yugo-nostalgia—the way in which the socialist past is re-created for a consumption-oriented present as one more marketing gimmick.Although focused on the case of Serbia and the troubled Milosevic era, it speaks to the broader theme of the fate of nationalism and national identity in an era of capitalist globalization. It also troubles the notion of modernization as a unified and unifying process by unfolding the complex mix of tradition and novelty, cosmopolitan aspiration, and historical identification that characterize not only the former Yugoslavia, but the process whereby nations are incorporated into the global market economy. Through the exploration of a particular case, the book explores the landscape of hopes and misgivings that characterize the post-Cold-War era. [ publisher's website]
The CHOP experience with cloacal exstrophy and gender reassignment.

We have chosen to emphasize our experience with the management of patients with cloacal exstrophy, because this is the primary patient population in which gender reassignment has been utilized at this center over a 30 year span. These 11 reassigned patients comprise a cohort with similar medical and surgical issues, and their progress may be contrasted with 4 males who were not gender reassigned as well as 7 genetic females. By gender reassignment, we are specifically referring to the assignment of a female gender for a neonate with an absent phallus who has a normal XY karyotype and functional testes in the absence of any endocrine disorder. Other reasons for gender reassignment within this department have included aphalia, ablatio penis, and one case of classic exstrophy. In addition to these extremely rare cases, the division has accumulated a substantial experience in gender assignment in intersex cases with the most common diagnosis being congenital adrenal hyperplasia. It has always been the philosophy of this division to assign a gender consistent with the chromosomal and gonadal sex whenever possible.
Community well being and infectious diseases among Alaska Native communities in the Chugach Region.

OBJECTIVES This study sought to examine how Native people of the Chugach Region of Alaska perceive their own communities' health and well being, particularly in regard to infectious diseases. STUDY DESIGN Prospective focus group interview survey. METHODS During September to December 1999, 12 focus groups were conducted in seven communities in the Chugach Region of Alaska with 97 participants. Using a set of eight questions, information gathered provided insights into the participants' health-related perceptions and provided previously nonexistent baseline data pertaining toTB and hepatitis. RESULTS Participants showed a good working knowledge of common infectious diseases. There were misconceptions and a potential for increased knowledge in highly prevalent diseases, but more recently delineated infections in rural Alaska, e.g., respiratory syncvtial virus (RSV), Helicobacter pylori, and less prevalent diseases, e.g., Acquired Immunodeficiency Syndrome (AIDS). The participants expressed a desire for further infectious disease information and dialogue. CONCLUSIONS This process can be used to develop a risk assessment tool for medical and clinical providers' use in an effort to increase testing for such infectious diseases as HIV, TB, Hepatitis C, and sexually transmitted diseases (STDs). In this case the authors also produced a STD prevention video for rural Alaska Natives, entitled, Summer Sun Winter Moon.
Reactions of Phosphorus Fertilizers with and without a Fertilizer Enhancer in Three Acidic Soils with High Phosphorus-Fixing Capacity

Limited P availability for plants in acidic soils is one of the key factors limiting crop production in many areas of the world. In this study, we investigated the mobility and availability of P in three different soil types (an Oxisol, an Andisol, and an Ultisol) and the fertilizer reaction products formed from three fertilizers: monoammonium phosphate (MAP), diammonium phosphate (DAP), and ammonium polyphosphate (APP). Additionally, we compared the effects of the fertilizers alone and enhanced with a fertilizer enhancement product (FEP) in the three soils. Soils were incubated for 5 wk in Petri dishes under seven treatments: each fertilizer with and without FEP, plus the unfertilized control. After incubation, soil samples were collected at varying distances from the point of P application. Measurements included soil pH, total P, resin-extractable P, scanning electron microscope-energy dispersive X-ray analysis of the P granules, and P reaction products measured via X-ray absorption near-edge structure spectroscopy (XANES). Phosphorus mobility with granular fertilizers was limited in the three soils but was enhanced in two for the liquid P treatments. The addition of FEP did not increase P mobility. Phosphorus source had variable effects on P lability for the three soils. The FEP produced greater P lability when combined with APP for one soil. Speciation influenced P lability in the soils in that increased Fe- and Fe-adsorbed P increased P extractability. There was not a consistent benefit of adding the FEP on the acidic high P-fixing soils.
Risk of severe infection following rituximab and the efficacy of antimicrobial prophylaxis.

We read with interest the article ‘Trimethoprim–sulfamethoxazole prophylaxis prevents severe/life-threatening infections following rituximab in antineutrophil cytoplasm antibody-associated vasculitis’ by Kronbichler et al .1 Severe infections continue to be a significant cause of morbidity and mortality in patients with anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV), and we commend the authors for pursuing this study. However, we have several concerns regarding their methodologies. First, more than 90% of patients with AAV analysed were prevalent cases. This may limit the generalisability of their findings to incident cases in whom there has been no prior treatment with cyclophosphamide or other immunosuppressive agents. As the authors note, there was an average delay of 4 years …
Clear plaque mutants of phage P7.

Abstract Clear plaque mutants of the P1-related phage P7 were isolated and classified by complementation tests with one another and with the P1 clear plaque mutants. In addition to several types of virulent mutants, a total of eight complementation groups of clear plaque mutants has been identified in these phages. A class of nonvirulent clear mutants unable to complement either P7c1 or P7c4 was also found. Mutants in this class have no genetic defect in the c4 region and are probably single mutants. Like c1ts lysogens of P1, P7c 1ts lysogens are thermally inducible, which supports the idea that gene c1 of both phages controls a repressor. P7c4 mutants cannot be complemented by any P1 clear mutants and P1c4 mutants cannot be complemented by any P7 clear mutants. This complementation behavior is expected if gene c4 codes for the immunity specific repressor in each of these heteroimmune phages. Unlike P1c4ts lysogens, P7c4ts lysogens are thermally induced to produce phage. This difference is discussed, but has not yet been explained.

Effects of Anticholinesterase Reversal Under General Anesthesia on Postoperative Cardiovascular Complications: A Retrospective Cohort Study.

BACKGROUND The anticholinesterase neostigmine and the muscarinic inhibitor glycopyrrolate are frequently coadministered for the reversal of neuromuscular blockade. This practice can precipitate severe bradycardia or tachycardia, but whether it affects the incidence of cardiovascular complications remains unclear. We hypothesized that anticholinesterase reversal with neostigmine and glycopyrrolate versus no anticholinesterase reversal increases the risk of postoperative cardiovascular complications among adult patients undergoing noncardiac surgery with general anesthesia. METHODS We conducted a prespecified retrospective analysis of hospital registry data from a major health care network for patients undergoing surgery with general anesthesia from January 2007 to December 2015. The primary outcome was a composite of cardiac dysrhythmia, acute heart failure, transient ischemic attack, ischemic stroke, and acute myocardial infarction within 30 days after surgery. We performed sensitivity analyses in subgroups and propensity score adjustment and explored the association between exposure and outcome in subgroups of patients with high risk of cardiovascular complications. RESULTS Of the 98,147 cases receiving neuromuscular blockade, 73,181 (74.6%) received neostigmine and glycopyrrolate, while 24,966 (25.4%) did not. A total of 5612 patients (7.7%) in the anticholinesterase reversal group and 1651 (6.6%) in the control group (P < .001) experienced the primary outcome. After adjustment for clinical covariates, neostigmine and glycopyrrolate exposure was significantly associated in a dose-dependent fashion (P for trend <.001, respectively) with tachycardia (adjusted odds ratio = 2.1 [95% CI, 1.97-2.23]; P < .001) and bradycardia (adjusted odds ratio = 2.84 [95% CI, 2.49-3.24]; P < .001) but not with postoperative cardiovascular complications (adjusted odds ratio = 1.03 [95% CI, 0.97-1.1]; P = .33). We identified a significant effect modification of anticholinesterase reversal by high age, high-risk surgery, and history of atrial fibrillation (P for interaction = .002, .001, and .02, respectively). By using linear combinations of main effect and exposure-risk interaction terms, we detected significant associations between anticholinesterase reversal and cardiovascular complications toward a higher vulnerability in these patient subgroups. CONCLUSIONS Neuromuscular blockade reversal with neostigmine and glycopyrrolate was associated with an increased incidence of intraoperative tachycardia and bradycardia but not with 30-day postoperative cardiovascular complications. Exploratory analyses suggest that a high postoperative cardiovascular complication risk profile may modify the effects of anticholinesterase reversal toward clinical relevance.
Genetic testing and eHealth usage among Deaf women.

In the past decade, accessible information in American Sign Language (ASL) about cancer and genetic testing is expanding on eHealth platforms, including social network sites, commercial sites, and mobile apps. Primary data on genetic testing awareness and genetic testing for BRCA 1/2 among Deaf women were gathered using HINTS-ASL survey between November 2016 and April 2018, and secondary data for hearing women were drawn from NCI’s HINTS 5 Cycle 1 survey in 2017. Deaf women who had heard of DNA testing (63%) were more likely to be young adults, college graduates, and/or have a family history of cancer. Compared to hearing women, Deaf women who had heard of genetic testing were more likely to use social networking sites to read or share information about medical topics and watch health-related videos. Making eHealth platforms accessible in ASL and easy-to-understand text can help reduce knowledge gap in genetic testing, since some Deaf women may not be using genetic testing to help identify whether they are at increased risk for breast and ovarian cancer early on, before they are diagnosed with cancer.
The $Z$-Polynomial of a Matroid

We introduce the $Z$-polynomial of a matroid, which we define in terms of the Kazhdan-Lusztig polynomial. We then exploit a symmetry of the $Z$-polynomial to derive a new recursion for Kazhdan-Lusztig coefficients. We solve this recursion, obtaining a closed formula for Kazhdan-Lusztig coefficients as alternating sums of multi-indexed Whitney numbers. For realizable matroids, we give a cohomological interpretation of the $Z$-polynomial in which the symmetry is a manifestation of Poincar e duality.
CityGuide: A Seamless Indoor-Outdoor Wayfinding System for People With Vision Impairments

GPS accuracy is poor in indoor environments and around buildings. Thus, reading and following signs still remains the most common mechanism for providing and receiving wayfinding information in such spaces. This puts individuals who are blind or visually impaired (BVI) at a great disadvantage. This work designs, implements, and evaluates a wayfinding system and smartphone application called CityGuide that can be used by BVI individuals to navigate their surroundings beyond what is possible with just a GPS-based system. CityGuide enables an individual to query and get turn-by-turn shortest route directions from an indoor location to an outdoor location. CityGuide leverages recently developed indoor wayfinding solutions in conjunction with GPS signals to provide a seamless indoor-outdoor navigation and wayfinding system that guides a BVI individual to their desired destination through the shortest route.

Characterization of an intermolecular quaternary interaction between discrete segments of the Streptococcus mutans adhesin P1 by NMR spectroscopy.

Cell surface-localized P1 adhesin (aka Antigen I/II or PAc) of the cariogenic bacterium Streptococcus mutans mediates sucrose-independent adhesion to tooth surfaces. Previous studies showed that P1's C-terminal segment (C123, AgII) is also liberated as a separate polypeptide, contributes to cellular adhesion, interacts specifically with intact P1 on the cell surface, and forms amyloid fibrils. Identifying how C123 specifically interacts with P1 at the atomic level is essential for understanding related virulence properties of S. mutans. However, with sizes of ~ 51 and ~ 185 kDa, respectively, C123 and full-length P1 are too large to achieve high-resolution data for full structural analysis by NMR. Here, we report on biologically relevant interactions of the individual C3 domain with A3VP1, a polypeptide that represents the apical head of P1 as it is projected on the cell surface. Also evaluated are C3's interaction with C12 and the adhesion-inhibiting monoclonal antibody (MAb) 6-8C. NMR titration experiments with 15 N-enriched C3 demonstrate its specific binding to A3VP1. Based on resolved C3 assignments, two binding sites, proximal and distal, are identified. Complementary NMR titration of A3VP1 with a C3/C12 complex suggests that binding of A3VP1 occurs on the distal C3 binding site, while the proximal site is occupied by C12. The MAb 6-8C binding interface to C3 overlaps with that of A3VP1 at the distal site. Together, these results identify a specific C3-A3VP1 interaction that serves as a foundation for understanding the interaction of C123 with P1 on the bacterial surface and the related biological processes that stem from this interaction.

Thermally-driven adsorption/desorption cycle for oxygen pumping in thermochemical fuel production

Abstract The two-step cycle for solar-thermochemical fuels production and thermochemical energy storage benefits from low oxygen partial pressure in the high-temperature thermal reduction step. To be practical, low oxygen partial pressures must be reached by energetically efficient and economically affordable methods—a challenge currently not met by either mechanical vacuum pumping or by inert gas sweeping. To address this challenge, we have examined a promising, thermally-driven surface adsorption/desorption approach. Providing that appropriately designed materials can be identified as expected, this approach would substantially advance solar-thermochemical fuel production (water and carbon dioxide splitting), thermochemical energy storage, and related technologies.
Intelligent Packaging as a Dynamic Marketing Tool for Tourism

In the age of immense technological developments, a large percentage of tourists, regardless of age, educational level and place of residence, seek knowledge and dynamic interaction in communication and processing of data to the visitor of the tourist area. The development of new technologies as well as the need of the tourist market with increasing demands (qualitative and quantitative) began to redefine the term of packaging (in the wider context of the concept) to the new data. In the field of tourism, the concept of intelligent packaging identifies systems and applications implemented by the packaging industry. Through the new information systems, new communication relationships between transmitter and receiver, tourists and exhibits are supported. The scientific space of Marketing promotes and upgrades, through the technological developments of intelligent systems, to tourism, as a dynamic tool, adapting the new needs of tourists, to the capabilities offered by intelligent systems that mainly concern mobile phone communication. Through new approaches to intelligent communication systems, new interactions are supported. The new formulas that exist on many levels in our society, combined with the innovative developments in electronic communication, shape the human culture and approach of the tourist visitor.
Metabolic-electrical control of coronary blood flow.

The heart is a metabolically demanding organ with limited energetic reserves to sustain its monumental workload. An efficient blood supply via the coronary vascular network is therefore critical for maintaining efficient cardiac muscle function. The coronary vascular network originates just above the aortic valve, where the right and left main coronary arteries connect to the ascending aorta. These arteries branch out into smaller-diameter arterioles that connect to capillaries, where oxygen exchange takes place (Fig. 1). In PNAS, Zhao et al. (1) describe a signaling pathway in the heart that couples metabolic changes in ventricular myocytes to hyperpolarization of capillary endothelial cells (cECs). This hyperpolarizing signal rapidly propagates throughout the arteriolar tree, causing vasodilation. The resulting upstream vasodilatory response is necessary to increase blood flow during periods of cardiac muscle metabolic stress to match oxygen supply with metabolic demands. The physiological implications of these findings are described below. Fig. 1. Metabolic–electrical signaling in the coronary vasculature. During resting conditions, cardiomyocytes (CMs) have high levels of intracellular ATP ([ATP]i) and low levels of extracellular K+ ([K+]o). Upon increased myocardial contraction, levels of [ATP]i decrease and [K+]o increases. Decreased [ATP]I levels trigger the activation of KATP channels expressed in the CM plasma membrane. Efflux of K+ ions induces hyperpolarization of CMs. Hyperpolarizing current passes to electrically coupled capillary endothelial cells (cECs) via gap junctions. The hyperpolarizing signal then travels in a retrograde direction along the cEC network to an upstream arteriole. This hyperpolarizing signal induces relaxation of the smooth muscle cells that encapsulate the coronary vasculature. A central tenet in cardiac physiology is that oxygen extraction efficiency is almost at saturation in the coronary circulation (2). Increasing oxygen demand is rapidly matched by increased blood flow via changes in perfusion pressure or vascular … [↵][1]1To whom correspondence may be addressed. Email: lfsantana{at}ucdavis.edu.

Evolutionary Algorithms for Vulnerability Coverage

We present a novel idea on adequacy testing called "vulnerability coverage." The introduced coverage measure examines the underlying software for the presence of certain classes of vulnerabilities often found in the National Vulnerability Database (NVD) website. The thoroughness of the test input generation procedure is performed through the adaptation of evolutionary algorithms namely Genetic Algorithms (GA) and Particle Swarm Optimization (PSO). The methodology utilizes the Common Vulnerability Scoring System (CVSS), a free and open industry standard for assessing the severity of computer system security vulnerabilities, as a fitness measure for test inputs generation. The outcomes of these evolutionary algorithms are then evaluated in order to identify the vulnerabilities that match a class of vulnerability patterns for testing purposes.

Head Orientation Monitoring with Wearable RFID for Detection of Lateral Glance of Children with Autism Spectrum Disorder

Some children with Autism Spectrum Disorder (ASD) show a symptom called lateral glance, which is a tendency of looking at objects out of corner of eye by turning head in the opposite direction. Since the lateral glance can negatively affect the muscles around the eyes and social interaction of the children, timely diagnosis, tracking and correction is very important. To overcome the limitations of the current eye-tracking device, a novel sensor using RFID (radio-frequency identification) tag was introduced. Four RFID tags were attached to the forehead area of a hat in two rows, and in each row difference of RSSI (Received signal strength indicator) of the tags were calculated. Result showed high correlation (>.93) between the sensor tracking and the head orientation angle which is the ground truth. RFID tags mounted on a hat showed a possibility of a battery-less, light and inexpensive wearable device for the children with ASD.
THE VOID-SIZE EFFECT ON PLASTIC FLOW LOCALIZATION FOR POROUS SOLIDS

Recent studies have shown that the size of microvoids has a significant effect on the void growth rate.The purpose of this paper is to explore whether the void size effect can influence plastic flow localization in ductile materials.We have used the extended Gurson’s dilatational plasticity theory,which accounts for the void size effect,to study plastic flow localization in porous solids.The localization model of Rice is adopted,in which the material inside the band may display different response from that outside the band at the incipient moment of plastic flow localization.The present study shows that the void size has some effect on the uniaxial tensile curves,but little or essentially no effect on the shear band angle.
