description: Glioblastoma (GBM) is a fatal cancer, thought to arise from astrocytes or precursors, including oligodendrocyte progenitor cells (OPCs). Although many of the key molecular alterations in GBM including p53 mutation and amplification of platelet derived growth factor receptor-alpha (PDGFR-a) are known, our understanding of this disease remains incomplete. Here, we show that cells from the subventricular zone of p53-/- mice growing m PDGF-A, transform giving rise to a population of cells that proliferate continuously in the absence of exogenous PDGF-A. When grafted into the brains of immunocompetent mice, they form cellular, invasive GBM-like tumors. This population of cells expresses PDGFR-a and Olig2, OPC markers. Thus, a subpopulation of PDGFR­a positive OPCs in the SVZ of adult p53-/- mice transform in the presence of PDGF-A. This model might be used to identify other molecular events that occur in secondary GBM, where early p53 and PDGFR-a alterations are signature genetic changes.

description: We consider the microscopic solutions of the Boltzmann-Enskog equation discovered by Bogolyubov. The fact that the time-irreversible kinetic equation has time-reversible microscopic solutions is rather surprising. We analyze this paradox and show that the reversibility or irreversibility property of the Boltzmann-Enskog equation depends on the considered class of solutions. If the considered solutions have the form of sums of delta-functions, then the equation is reversible. If the considered solutions belong to the class of continuously differentiable functions, then the equation is irreversible. Also, we construct the so called approximate microscopic solutions. These solutions are continuously differentiable and they are reversible on bounded time intervals. This analysis suggests a way to reconcile the time-irreversible kinetic equations with the time-reversible particle dynamics. Usually one tries to derive the kinetic equations from the particle dynamics. On the contrary, we postulate the Boltzmann-Enskog equation or another kinetic equation and treat their microscopic solutions as the particle dynamics. So, instead of the derivation of the kinetic equations from the microdynamics we suggest a kind of derivation of the microdynamics from the kinetic equations.

description: Quantum key distribution (QKD) takes advantage of fundamental properties of quantum physics to allow two distant parties to share a secret key; however, QKD is hampered by a distance limitation of a few hundred kilometers on earth. The most immediate solution for global coverage is to use a satellite, which can receive separate QKD transmissions from two or more ground stations and act as a trusted node to link these ground stations. In this article, we report a system capable of performing QKD in the high loss regime expected in an uplink to a satellite using weak coherent pulses and decoy states. Such a scenario profits from the simplicity of its receiver payload, but has so far considered to be infeasible due to very high transmission losses (40 - 50 dB). The high loss is overcome by implementing an innovative photon source and advanced timing analysis. Our system handles up to 57 dB photon loss in the infinite key limit, confirming the viability of the satellite uplink scenario. We emphasize that while this system was designed with a satellite uplink in mind, it could just as easily overcome high losses on any free space QKD link.

description: In 2009 the Florida Fish and Wildlife Conservation Commission (FWC) began surveying individuals who reported human-bear conflicts. The purpose of this survey is to assess whether individuals take actions recommended by the FWC to reduce or eliminate conflicts. Using this data set, we determined which factors influence the likelihood that surveyed individuals will follow the advice provided by the FWC for managing human-bear conflicts. We find outreach efforts by the FWC increase the probability that people who report conflicts to the agency adopt recommended measures to reduce these conflicts. Our results suggest that outreach efforts by wildlife agencies increase the likelihood that people will alter their behavior to reduce human-bear conflicts.

description: A distributed sensor system is highly desirable for detecting, locating, and monitoring fine cracks at unknown locations in advanced ceramics. This paper presents a distributed high-resolution fiber optic sensor based on the Brillouin scattering principle, and its application in ceramic crack detection for the first time. The existence of cracks, together with their locations, is identified by measuring the strain distribution on a sensing fiber bonded to the ceramic surface. By employing the innovative coherent probe-pump interaction technique, the Brillouin sensor developed in this study achieves a high spatial resolution (100 mm) and measurement accuracy. Capable of detecting and locating fine cracks less than 40 μm, the efficacy of the distributed Brillouin fiber optic sensor is demonstrated through experiments.

description: The possible heavy fermion superconductivity is carefully reexamined in the two-dimensional Kondo lattice model with an antiferromagnetic Heisenberg superexchange between local magnetic moments. In order to establish an effective mean field theory in the limit of the paramagnetic heavy Fermi liquid and near the half-filling case, we find that the spinon singlet pairing from the local antiferromagnetic short-range correlations can reduce the ground state energy substantially. In the presence of the Kondo screening effect, the Cooper pairs between the conduction electrons is induced. Depending on the ratio of the Heisenberg and the Kondo exchange couplings, the resulting superconducting state is characterized by either a d-wave nodal or d-wave nodeless state, and a continuous phase transition exists between these two states. These results are related to some quasi-two dimensional heary fermion superconductors.

description: This cross-sectional study empirically evaluated a model designed to predict the varied elements influencing the behavioural intents of financial institutions towards the use of mobile peer-to-peer platforms. Combining behavioural and instrument elements from frameworks based on the Net Valence Theory and the Theory of Reasoned Action, this study examined behavioural intention from the standpoint of financial institutions. An online survey of 88 organizations yielded data analyzed using PLS-SEM for hypothesis testing. The findings revealed that (1) instrument mobile perceived trust is a good mediator of heterogeneous factors, including economic ones, (2) the perceived risk has no effect when a mobile perceived trust significantly influences the intention, (3) the mobile perceived usefulness plays no role in the new mobile context, and (4) the combination of behavioural (extrinsic) and instrument (intrinsic) factors is vital and significant in mobile financial business models. In addition, the results suggest that practitioners concentrate on perceived mobile trust, perceived convenience, perceived economics, and perceived mobile ease of use as the primary drivers of mobile peer-to-peer platform adoption. These elements considerably increase the rate of mobile peer-to-peer platform adoption. Therefore, FinTech and mobile technology regulators are recommended to establish a regulatory framework that helps financial institutions regard mobile as trustworthy
Quantum continuum mechanics in a strong magnetic field

description: We extend a recent formulation of quantum continuum mechanics [J. Tao et. al, Phys. Rev. Lett. {\bf 103}, 086401 (2009)] to many-body systems subjected to a magnetic field. To accomplish this, we propose a modified Lagrangian approach, in which motion of infinitesimal volume elements of the system is referred to the "quantum convective motion" that the magnetic field produces already in the ground-state of the system. In the linear approximation, this approach results in a redefinition of the elastic displacement field $\uv$, such that the particle current $\jv$ contains both an electric displacement and a magnetization contribution: $\jv=\jv_0+n_0\partial_t \uv+\nabla \times (\jv_0\times \uv)$, where $n_0$ and $\jv_0$ are the particle density and the current density of the ground-state and $\partial_t$ is the partial derivative with respect to time. In terms of this displacement, we formulate an "elastic approximation" analogous to the one proposed in the absence of magnetic field. The resulting equation of motion for $\uv$ is expressed in terms of ground-state properties -- the one-particle density matrix and the two-particle pair correlation function -- and in this form it neatly generalizes the equation obtained for vanishing magnetic field.

description: Bibliography: p. 81-97
description: Hemandulcin, a C 15 sesquiterpene ketone, is a natural sweetener isolated from the leaves of Lippia dulcis, an indigenous plant to the Central America. Hernandulcin is a promising sugar substitute due to its safety and low caloric potential. However, its biosynthesis in L. dulcis remains unknown. The first biochemical step in hemandulcin biosynthetic pathway is the synthesis of (+)-epi-a-bisabolol from famesyl diphosphate, which is presumed to be catalyzed by a unique sesquiterpene synthase in L. dulcis. To identify(+)­epi-a-bisabolol synthase gene in L. dulcis, deep transcript sequencings ( 454 and Illumina) were performed and five potential candidates were identified by bioinformatic analysis. One of these candidates was successfully identified as a-bisabolol synthase by in vivo functional characterization in metabolically engineered yeast. Deep structural analysis of the produced a-bisabolol confirmed its configuration to be ( + )-epi-a-bisabolol, the core skeleton of hemandulcin. Bisabolol yield from the engineered yeast was quantified and kinetic constants of the identified ( + )-epi-a-bisabolol synthase were determined.

description: In the effort to characterize the masses, radii, and atmospheres of potentially habitable exoplanets, there is an urgent need to find examples of such planets transiting nearby M dwarfs. The MEarth Project is an ongoing effort to do so, as a ground-based photometric survey designed to detect exoplanets as small as 2 Earth radii transiting mid-to-late M dwarfs within 33 pc of the Sun. Unfortunately, identifying transits of such planets in photometric monitoring is complicated both by the intrinsic stellar variability that is common among these stars and by the nocturnal cadence, atmospheric variations, and instrumental systematics that often plague Earth-bound observatories. Here we summarize the properties of MEarth data gathered so far, and we present a new framework to detect shallow exoplanet transits in wiggly and irregularly-spaced light curves. In contrast to previous methods that clean trends from light curves before searching for transits, this framework assesses the significance of individual transits simultaneously while modeling variability, systematics, and the photometric quality of individual nights. Our Method for Including Starspots and Systematics in the Marginalized Probability of a Lone Eclipse (MISS MarPLE) uses a computationally efficient semi-Bayesian approach to explore the vast probability space spanned by the many parameters of this model, naturally incorporating the uncertainties in these parameters into its evaluation of candidate events. We show how to combine individual transits processed by MISS MarPLE into periodic transiting planet candidates and compare our results to the popular Box-fitting Least Squares (BLS) method with simulations. By applying MISS MarPLE to observations from the MEarth Project, we demonstrate the utility of this framework for robustly assessing the false alarm probability of transit signals in real data.

description: Although most women infected with HIV are intravenous drug users, some contact the virus through sexual contact with IV drug users. To reach at-risk women, public health officials must develop a range of prevention strategies. One approach, skills training, holds promise as a means of altering risk-related sexual behavior. In this study, 91 women methadone patients were pretested and randomly assigned to an information-only control control group or a skills-building intervention group. Skills-building intervention consisted of five sessions of small groups in which participants identified their own high risk sexual behaviors, discussed their negative associations with condoms, and practiced skills which involved asking partners to use condoms. Compared with members of the control group, respondents in the intervention group reported that they initiated discussion of sexual issues with their partners more frequently, felt more comfortable talking with them about safer sex, and reported using and carrying condoms more frequently. The high rates of attendance and program retention by skills-building participants suggest that such groups may be supportive and useful in the design of risk reduction and drug abuse treatment programs. The modest outcomes of this study underscore the difficulty of altering risk behavior but also serve as a basis for future AIDS prevention studies.

description: Over the past 20 years, the increasing demand for the delivery of public services and infrastructures has created a need to for new and effective delivery strategies. In the early 1990s, public-private partnerships were proposed as one such solution to help government cope with the growing demand of public services. However, a number of issues were encountered worldwide in the implementation of PPPs. Saudi Arabia, similar to other countries, has faced problems implementing PPPs to manage associated complex PPP arrangements. Therefore, this thesis has focused on studying the initiated public-private partnership (PPP) guidelines/frameworks governing PPPs within Saudi Arabia's infrastructure sectors to improve their implemented practices. The research was developed based on the qualitative data collected from two case studies. This multiple case study approach was used to understand and describe: the rationale and government objectives for choosing a PPP; the challenges facing the public and private sectors in planning and developing PPP projects; interrelationships of different variables associated with PPP projects; institutional capacity of public sectors for delivering PPPs; and the PPP market drivers. Data analysis has revealed four significant barriers: lack of political will and support, legal and regulatory, institutional capacity and expertise, and market maturity. In response to these weaknesses, the researcher has suggested a framework for improving market maturity to enable a more successful implementation. The main function of the suggested framework is to guide public sectors and policy makers who are interested in a more effective implementation of PPPs. The development of this framework was based on the insights gained from the analyses of case studies and discussions with experts and international best practices. It also focuses on ways to avoid the identified failures and explains how to overcome the challenges related to the Saudi PPP market. The proposed framework includes key elements (political will, legal and regulatory context, institutional context and market maturity) and their related attributes which governments must consider carefully when proceeding with PPP implementation.

description: We investigate an optical quantum memory scheme with V-type three-level atoms based on the controlled reversible inhomogeneous broadening (CRIB) technique. We theoretically show the possibility to store and retrieve a weak light pulse interacting with the two optical transitions of the system. This scheme implements a quantum memory for a polarization qubit - a single photon in an arbitrary polarization state - without the need of two spatially separated two-level media, thus offering the advantage of experimental compactness overcoming the limitations due to mismatching and unequal efficiencies that can arise in spatially separated memories. The effects of a relative phase change between the atomic levels, as well as of phase noise due to, for example, the presence of spurious electric and magnetic fields are analyzed.

description: We study Maxwell's equations on a 4-manifold N with a medium that is non-dissipative and has a linear and pointwise response. In this setting, the medium can be represented by a suitable (2,2)-tensor on the 4-manifold N. Moreover, in each cotangent space on N, the medium defines a Fresnel surface. Essentially, the Fresnel surface is a tensorial analogue of the dispersion equation that describes the response of the medium for signals in the geometric optics limit. For example, in isotropic medium the Fresnel surface is at each point a Lorentz light cone. In a recent paper, I. Lindell, A. Favaro and L. Bergamin introduced a condition that constrains the polarisation for plane waves. In this paper we show (under suitable assumptions) that a slight strengthening of this condition gives a pointwise characterisation of all medium tensors for which the Fresnel surface is the union of two distinct Lorentz null cones. This is for example the behaviour of uniaxial medium like calcite. Moreover, using the representation formulas from Lindell et al. we obtain a closed form representation formula that pointwise parameterises all medium tensors for which the Fresnel surface is the union of two distinct Lorentz null cones. Both the characterisation and the representation formula are tensorial and do not depend on local coordinates.

description: We examined the network profiles and social supports of 151 women on methadone, exploring to whom women turn for different types of support and how flow of support is associated with the network member's personal and relational characteristics and network structure. Women reported a total of 795 network members, with an average network size of 5.9 individuals. The networks were long“ term, ethnically homogeneous, and of high density. Support within personal networks is contingent on the types of support required, the relational characteristics, and the network structures. Findings from this study may be useful in helping practitioners and program developers to better comprehend the social milieu of drug users, particularly women enrolled in methadone treatment programs.

Role of the RhoA/ROCK pathway in hypertension associated with diabetes
Creators: name: Rao, Milly Yushu
Publisher: name: University of British Columbia
Year: 2011

description: Hypertension is the most common cardiovascular complication associated with diabetes mellitus. The RhoA/ROCK pathway has been implicated in the regulation of vascular smooth muscle contractile responses associated with hypertension and diabetes. Here we wished to determine the role of the RhoA/ROCK pathway in vascular smooth muscle contractile responses in different types of diabetic models and its contribution to diabetes-associated hypertension. Our results suggest that the involvement of ROCK may be more important in U-46619- than in PE-induced contractile responses in endothelium denuded mesenteric resistance arteries from control rats. On the other hand, as found in our previous work and other reports, PE-induced contractile responses were attenuated by inhibition of ROCK in rat superior mesenteric arteries, suggesting that ROCK is likely to play an essential role in PE-induced contraction in superior mesenteric arteries. Blood pressure in GK rats was normalized by one-week treatment with fasudil, a known ROCK inhibitor, suggesting that the elevated blood pressure in GK rats may be due to enhanced ROCK pathway. However, agonist-induced contractile responses in GK mesenteric resistance arteries were not augmented compared to control arteries, and moreover, expression of ROCK/RhoA as well as activity of ROCK were similar between control and GK arteries. The specific causes of the discrepancy remain unknown. In the presence of L-NAME, ROCK inhibitor significantly attenuated contraction induced by PE or U-46619 in mesenteric resistance arteries from GK rats, suggesting that agonist-induced contractile responses in mesenteric resistance arteries from GK rats were likely to be ROCK-mediated. This was further supported by Western blotting results, in that phosphorylation of MYPT was significantly increased by U-46619. Interestingly, U-46619-induced contraction in mesenteric resistance arteries from control rats was no longer sensitive to inhibition of ROCK in the presence of L-NAME, although the reasons were unclear. In conclusion, results from the GK rat study do not support the hypothesis that activation of the RhoA/ROCK pathway contributes to the development of diabetes-associated hypertension in GK rats by enhancing vascular smooth muscle contractile responses. To further investigate this study, a more ROCK selective ROCK inhibitor is needed.

description: Non-infectious equine respiratory diseases consist of recurrent airway obstruction (RAO) and inflammatory airway disease (IAD). Recurrent airway obstruction has similarities with human asthma, whereas horses with IAD have a milder airway inflammation and do not exhibit respiratory clinical signs at rest. This thesis presents a review on RAO and IAD, followed by a manuscript on the evaluation of a risk-screening questionnaire (RSQ) to detect equine lung inflammation measured by a bronchoalveolar lavage (BAL) in a large field study. The RSQ had a high sensitivity to detect severe lower airway inflammation and would be a good screening tool in practice. Furthermore, there was a high prevalence of moderate airway inflammation in this population, but the RSQ did not differentiate between moderate airway inflammation and normal horses. Finally feeding round hay bales was a risk factor for severe airway inflammation.

description: Objectives. We examined the associations between posttraumatic stress disorder (PTSD) and HIV risk behaviors among a random sample of 241 low-income women receiving care in an urban emergency department. Methods. We recruited participants from the emergency department waiting room during randomly selected 6-hour blocks of time. Multivariate analyses and propensity score weighting were used to examine the associations between PTSD and HIV risk after adjustment for potentially confounding sociodemographic variables, substance use, childhood sexual abuse, and intimate partner violence. Results. A large majority of the sample self-identified as Latina (49%) or African American (44%). Almost one third (29%) of the participants met PTSD criteria. Women who exhibited symptoms in 1 or more PTSD symptom clusters were more likely than women who did not to report having had sex with multiple sexual partners, having had sex with a risky partner, and having experienced partner violence related to condom use in the preceding 6 months. Conclusions. The high rate of PTSD found in this sample and the significant associations between PTSD symptom clusters and partner-related risk behaviors highlight the need to take PTSD into account when designing HIV prevention interventions for low-income, urban women.
Societal Responses to Terrorist Attacks

Subjects: Social psychology

description: Terrorist attacks in the United States and in Western Europe have been rare, and public awareness of the terrorist menace has largely been molded by a few horrific events. In contrast, other countries have experienced chronic terrorism, with attacks on buses, restaurants, coffee shops, and retail establishments. In this review, we assess the impact of terrorism on civilian society in the United States, Northern Ireland, and Israel. We examine the psychological effects, the adaptations made by individuals to enhance their safety, and the consequent adjustments made by institutional actors and by commercial establishments to ensure continued economic viability. We review the various theories of societal adjustments to exogenous shocks and point out that a very different formulation is required for the case of chronic terrorism than for the societal experience of a one-time attack.

description: We analyze the Block Averaging Transformation applied to the two--dimensional Ising model in the uniqueness region. We discuss the Gibbs property of the renormalized measure and the convergence of renormalized potential under iteration of the map. It turns out that for any temperature $T$ higher than the critical one $T_c$ the renormalized measure is strongly Gibbsian, whereas for $TT_c$ and in a weak sense for $T

description: The HIV epidemic has been continuously growing among women, and in some parts of the world, HIV-infected women outnumber men. Women's greater vulnerability to HIV, both biologically and socially, influences their health risk and health outcome. This disparity between sexes has been established for other diseases, for example, autoimmune diseases, malignancies and cardiovascular diseases. Differences in drug effects and treatment outcomes have also been demonstrated. Despite proven sex and gender differences, women continue to be underrepresented in clinical trials, and the absence of gender analyses in published literature is striking. There is a growing advocacy for consideration of women in research, in particular in the HIV field, and gender mainstreaming of policies is increasingly called for. However, these efforts have not translated into improved reporting of sex-disaggregated data and provision of gender analysis in published literature; science editors, as well as publishers, lag behind in this effort. Instructions for authors issued by journals contain many guidelines for good standards of reporting, and a policy on sex-disaggregated data and gender analysis should not be amiss here. It is time for editors and publishers to demonstrate leadership in changing the paradigm in the world of scientific publication. We encourage authors, peer reviewers and fellow editors to lend their support by taking necessary measures to substantially improve reporting of gender analysis. Editors' associations could play an essential role in facilitating a transition to improved standard editorial policies.

description: Human-wildlife conflicts have drastically increased around conservation areas in Africa in recent decades, thus undermining the peaceful cohabitation of wildlife populations and rural human settlements. Mitigation packages include various reporting forms, which are often ineffective since the information conveyed is generally scattered and useless. The booming mobile phone sector and the popular use of text messages (SMS) have provided an opportunity to assess the impact of real-time communication systems in human-wildlife conflict mitigation strategies. After preliminary tests conducted in Mozambique and Zimbabwe with FrontlineSMS, we improved the recording and transfer of raw information generated at field level with the development of an integrated system called SYSMAS. Apart from improving the quality of wildlife based information, SYSMAS was developed as a handy management tool informing in real time decision makers and easy to upload even without specific computer skills. This paper details how easy any human-wildlife conflict incident or wildlife event can be translated into a set of explanatory variables and captured on mobile phones with ad-hoc SMS models. According to local communication facilities, real-time sharing of the information could be achieved directly through a Web interface or via SMS; this last been more handy in remote African farmland. Once adopted, such a human-wildlife conflict early warning system could be deployed at low cost. The same approach could be promoted for the establishment of reporting systems on wildlife disease outbreaks.

description: This dissertation examines the construct of sustainability, its role as a product attribute, and the influence of situational factors on sustainable product decisions. While past research in sustainable behaviours has largely focused on measuring and identifying individual difference variables that will influence behaviours, this dissertation examines marketing controlled situational variables, such as product, promotion and signals of credibility, which may encourage greater engagement with sustainable initiatives, thus expanding the traditional focus on individual differences. In three essays that employ three different methods, this research contributes to sustainability and marketing literatures as it elucidates consumer perceptions of sustainability, highlights the influence of situational factors, and examines the effectiveness of persuasion techniques in highly skeptical consumer domains. Collectively the results support the argument that a one­dimensional environmental operationalization of sustainability may be underestimating the importance of the other dimensions in consumer perceptions. Additionally, the research supports the argument for the consideration of marketing-controlled situational variables in the study of sustainable consumer behaviours. The role of confidence is presented as means of countering consumer skepticism in the domain of sustainable products, and the moderating influence of skepticism on the persuasive effects of credibility signals is demonstrated.
