description: We have undertaken a new ground-based monitoring campaign to improve the estimates of the mass of the central black hole in NGC 4151. We measure the lag time of the broad H beta line response compared to the optical continuum at 5100 A and find a lag of 6.6 (+1.1/-0.8) days. We combine our data with the recent reanalysis of UV emission lines by Metzroth et al. to calculate a weighted mean of the black hole mass, M_BH = 4.57 (+0.57/-0.47) x 10^7 M_sun. The absolute calibration of the black hole mass is based on normalization of the AGN black hole mass - stellar velocity dispersion (M_BH - sigma_*) relationship to that of quiescent galaxies by Onken et al. The scatter in the M_BH - sigma_* relationship suggests that reverberation-mapping based mass measurements are typically uncertain by a factor of 3-4.

description: Objective: To determine if baseline measurements of cerebral atrophy and severity of white matter hyperintensity (WMH) predict the rate of future cognitive decline in patients with Alzheimer disease (AD). Design: Data were drawn from the Predictors Study, a longitudinal study that enrolls patients with mild AD and reassesses them every 6 months with use of the Columbia modified Mini-Mental State (mMMS) examination (score range, 0-57). Magnetic resonance images were analyzed to determine the severity of WMH, using the Scheltens scale, and the degree of atrophy, using the bicaudate ratio. Generalized estimating equations were used to determine whether severity of baseline magnetic resonance image measurements and their interaction predicted the rate of mMMS score decline at subsequent visits. Setting: Three university-based AD centers in the United States. Participants: At baseline, 84 patients with AD from the Predictors Study received structural magnetic resonance imaging and were selected for analysis. They had a mean of 6 follow-up evaluations. Main Outcome Measure: The mMMS score. Results: Generalized estimating equation models demonstrated that the degree of baseline atrophy (β = −0.316; P = .04), the severity of WMH (β = −0.173; P = .03), and their interaction (β = −6.061; P = .02) predicted the rate of decline in mMMS scores. Conclusions: Both degree of cerebral atrophy and severity of WMH are associated with the rapidity of cognitive decline in AD. Atrophy and WMH may have a synergistic effect on future decline in AD, such that patients with a high degree of both have a particularly precipitous cognitive course. These findings lend further support to the hypothesis that cerebrovascular pathological abnormalities contribute to the clinical syndrome of AD.
A New Look at the Quantum Mechanics of the Harmonic Oscillator

description: Classically the Harmonic Oscillator (HO) is the generic example for the use of angle and action variables phi in R mod 2 pi and I > 0. But the symplectic transformation (ϕ,I) to (q,p) is singular for (q,p) = (0,0). Globally {(q,p)} has the structure of the plane R^2, but {(phi,I)} that of the punctured plane R^2 -(0,0). This implies qualitative differences for the QM of the two phase spaces: The quantizing group for the plane R^2 consists of the (centrally extended) translations generated by {q,p,1}, but the corresponding group for {(phi,I)} is SO(1,2) = Sp(2,R)/Z_2, (Sp(2,R): symplectic group of the plane), with Lie algebra basis {h_0 = I, h_1 = I cos phi, h_2 = - I sin phi}. In the QM for the (phi,I)-model the three h_j correspond to self-adjoint generators K_j, j=0,1,2, of irreducible unitary representations (positive discrete series) for SO(1,2) or one of its infinitely many covering groups, the Bargmann index k > 0 of which determines the ground state energy E (k, n=0) = hbar omega k of the (phi,I)-Hamiltonian H(K). For an m-fold covering the lowest possible value is k=1/m, which can be made arbitrarily small! The operators Q and P, now expressed as functions of the K_j, keep their usual properties, but the richer structure of the K_j quantum model of the HO is ``erased'' when passing to the simpler Q,P model! The (phi,I)-variant of the HO implies many experimental tests: Mulliken-type experiments for isotopic diatomic molecules, experiments with harmonic traps for atoms, ions and BE-condensates, with the (Landau) levels of charged particles in magnetic fields, with the propagation of light in vacuum, passing through electric or magnetic fields. Finally it leads to a new theoretical estimate for the quantum vacuum energy of fields and its relation to the cosmological constant.

description: Under the security dilemma, tensions and conflicts can arise between states even when they do not intend them. Some analysts have argued that the Cold War was a classic example of a security dilemma. This article disputes that notion. Although the Cold War contained elements of a deep security dilemma, it was not purely a case in which tensions and arms increased as each side defensively reacted to the other. The root of the conflict was a clash of social systems and of ideological preferences for ordering the world. Mutual security in those circumstances was largely unachievable. A true end to the Cold War was impossible until fundamental changes occurred in Soviet foreign policy.

The legal regime of international straits : a case study of the legal and political implications for the Strait of Hormuz
Creators: name: Al Sheddi, Abdullah
Publisher: name: University of British Columbia
Year: 2012

description: This thesis is an analytical study of the legal and political aspects of the Strait of Hormuz. It involves an evaluation of the policies of the Gulf States towards the applicable legal regime of passage through the Strait of Hormuz and their reactions towards both the 1958 and 1982 conventions on the Law of the Sea. Special attention is made to the practice of the States bordering the Strait of Hormuz as contained in their national laws. Our analysis of the applicable legal regime of passage through the Strait of Hormuz is conducted in the light of the prevailing international rules governing passage through international straits. Extensive discussion is devoted to the principal sources of threats to the Gulf’s security and to the safety of navigation through the Gulf Sea lanes, including the Strait of Hormuz.

The model includes localization by disorder and predicts a power-law thermal scaling of the effective homogeneous line width. The theory gives excellent agreement with temperature dependent absorption and hole-burning experiments on aggregates of the dye pseudoisocyanine.

description: Understanding how properties of materials change due to nuclear transmutations is a major challenge for the design of structural components for a fusion power plant. In this study, by combining a first-principles matrix Hamiltonian approach with thermodynamic integration we investigate quasi-steady state configurations of multi-component alloys, containing defects, over a broad range of temperature and composition. The model enables simulating transmutation-induced segregation effects in materials, including tungsten where the phenomenon is strongly pronounced. Finite-temperature analysis shows that voids are decorated by Re and Os, but there is no decoration by tantalum (Ta). The difference between the elements is correlated with the sign of the short range order (SRO) parameter between impurity and vacancy species, in agreement with Atom Probe Tomography (APT) observations of irradiated W-Re, W-Os, W-Ta alloys in the solid solution limit. Statistical analyses of Re and Os impurities in vacancy-rich tungsten show that the SRO effects involving the two solutes are highly sensitive to the background concentration the species. In quaternary W-Re-Os-Vac alloys containing 1.5% Re and 0.1% Os, the SRO Re-Os parameter is negative at 1200K, driving the formation of concentrated Re and Os precipitates. Comparison with experimental Transmission Electron Microscopy (TEM) and APT data on W samples irradiated at the High Flux Reactor (HFR) shows that the model explains the origin of anomalous segregation of transmutation products (Re,Os) to vacancy clusters and voids in the high temperature limit pertinent to the operating conditions of a fusion power plant.

description: Since 1993, in response to a movement sponsored by the Southern Baptist Church, over 2.5 million adolescents have taken public “virginity” pledges, in which they promise to abstain from sex until marriage. This paper explores the effect of those pledges on the transition to first intercourse. Adolescents who pledge are much less likely to have intercourse than adolescents who do not pledge. The delay effect is substantial. On the other hand, the pledge does not work for adolescents at all ages. Second, pledging delays intercourse only in contexts where there are some, but not too many, pledgers. The pledge works because it is embedded in an identity movement. Consequently, the pledge identity is meaningful only in contexts where it is at least partially nonnormative. Consequences of pledging are explored for those who break their promise. Promise breakers are less likely than others to use contraception at first intercourse.

description: In a semiclassically quantized two-dimensional cosmological model, it can be shown that the parameter of the equation of state for the accelerating universe can be positive due to the negative energy density and the negative pressure, which is a little different from the conventional wisdom that the parameter is negative with the positivity of the energy density. Furthermore, we show that the full parameter composed of the classical and the quantum-mechanical contributions is positive and finite even though the partial state parameter from the quantum-mechanical contribution is not positive definite, which means that the state parameter is not perturbatively additive in this model.

description: Human angiosarcoma and canine hemangiosarcoma are thought to arise from vascular tissue or vascular forming cells based upon their histological appearance. However, recent evidence indicates a hematopoietic or angioblastic cell of origin for these tumors. In support of this idea, we previously identified an endothelial-myeloid progenitor cell population with high expression of endothelial cell markers and the myeloid cell marker, colony stimulating factor 1 receptor (CSF-1R). Here, we further characterized these cells to better understand how their cellular characteristics may impact current therapeutic applications. We performed cell enrichment studies from canine hemangiosarcoma and human angiosarcoma cell lines to generate cell populations with high or low CSF-1R expression. We then utilized flow cytometry, side population and cell viability assays, and fluorescence based approaches to elucidate drug resistance mechanisms and to determine the expression of hematopoietic and endothelial progenitor cell markers. We demonstrated that cells with high CSF-1R expression enriched from hemangiosarcoma and angiosarcoma cell lines are more drug resistant than cells with little or no CSF-1R expression. We determined that the increased drug resistance may be due to increased ABC transporter expression in hemangiosarcoma and increased drug sequestration within cellular lysosomes in both hemangiosarcoma and angiosarcoma. We identified drug sequestration within cellular lysosomes as a shared drug resistance mechanism in human and canine vascular sarcomas marked by high CSF-1R expression. Taken together, our results demonstrate that studies in highly prevalent canine hemangiosarcoma may be especially relevant to understanding and addressing drug resistance mechanisms in both the canine and human forms of this disease.
Utilization, Attitudes, and Experiences of Vietnam Era Veterans with Veterans Administration Health Facilities: The American Legion Experience

description: A random sample of American Legion members in six states who had served in the Armed Forces during the Vietnam Era was conducted through a mailed questionnaire, in order to determine patterns of usage of Veterans Administration health facilities, as well as attitudes toward the VA and experiences at these facilities. Of the 6810 male respondents, 42.0% had served in Southeast Asia. These subjects were categorized according to their level of combat in South Vietnam. Thirty-six percent of those who had served in Southeast Asia had used VA health facilities, compared to only 18% of men who served elsewhere. Among Southeast Asia veterans, combat level was an important predictor of extent of usage of VA facilities for problems of both physical and mental health. Combat level was also associated with lack of basic and major medical insurance. While men with lower incomes tended to make greater use of VA mental health facilities, nearly one-fourth of mental health users had family incomes above $30,000. Despite their greater usage of the VA, men with higher combat levels expressed lower feelings of security about this agency, and rated its staff less helpful and of lower quality than did men who experienced lower levels of combat. On the other hand, higher combat veterans thought themselves better informed about VA services. Men who had gone to the VA for mental health assistance reported a disturbingly low frequency of having been asked basic questions that relate to possible diagnosis of post-traumatic stress disorder (PTSD), questions related to combat, which may be one of its etiologic factors, or other questions relating to their military history'. Because combat level in Vietnam veterans is a major determinant of both attitudes toward and utilization of VA health facilities, the VA as well as other health agencies which deal with Vietnam veterans should be especially sensitive to this factor, and should take it into consideration when evaluating veterans' physical and mental health.
Low energy theory of a single vortex and electronic quasiparticles in a d-wave superconductor

description: We highlight the properties of a simple model (contained in our recent work) of the quantum dynamics of a single point vortex interacting with the nodal fermionic quasiparticles of a d-wave superconductor. We describe the renormalization of the vortex motion by the quasiparticles: at T=0, the quasiparticles renormalize the vortex mass and introduce only a weak sub-Ohmic damping. Ohmic (or `Bardeen-Stephen' damping) appears at T>0, with the damping co-efficient vanishing ~ T^2 with a universal prefactor. Conversely, quantum fluctuations of the vortex renormalize the quasiparticle spectrum. A point vortex oscillating in a harmonic pinning potential has no zero-bias peak in the electronic local density of states (LDOS), but has small satellite features at an energy determined by the pinning potential. These are proposed as the origin of sub-gap LDOS peaks observed in scanning tunneling microscopic studies of the LDOS near a vortex.

description: As more exoplanets are being discovered around ultracool dwarfs, understanding their magnetic activity -- and the implications for habitability -- is of prime importance. To find stellar flares and photometric signatures related to starspots, continuous monitoring is necessary, which can be achieved with spaceborn observatories like the Transiting Exoplanet Survey Satellite (TESS). We present an analysis of TRAPPIST-1 like ultracool dwarfs with TESS full-frame image photometry from the first two years of the primary mission. A volume-limited sample up to 50 pc is constructed consisting of 339 stars closer than 0.5 mag to TRAPPIST-1 on the Gaia colour-magnitude diagram. The 30-min cadence TESS light curves of 248 stars were analysed, searching for flares and rotational modulation caused by starspots. The composite flare frequency distribution of the 94 identified flares shows a power law index similar to TRAPPIST-1, and contains flares up to $E_\mathrm{TESS} = 3 \times 10^{33}$ erg. Rotational periods shorter than 5 days were determined for 42 stars, sampling the regime of fast rotators. The ages of 88 stars from the sample were estimated using kinematic information. A weak correlation between rotational period and age is observed, which is consistent with magnetic braking.

description: The SARS-CoV-2 Omicron variants of concern (VOCs) showed severe resistance to the early-approved COVID-19 vaccines-induced immune responses. The breakthrough infections by the Omicron VOCs are currently the major challenge for pandemic control. Therefore, booster vaccination is crucial to enhance immune responses and protective efficacy. Previously, we developed a protein subunit COVID-19 vaccine ZF2001, based on the immunogen of receptor-binding domain (RBD) homodimer, which was approved in China and other countries. To adapt SARS-CoV-2 variants, we further developed chimeric Delta-Omicron BA.1 RBD-dimer immunogen which induced broad immune responses against SARS-CoV-2 variants. In this study, we tested the boosting effect of this chimeric RBD-dimer vaccine in mice after priming with two doses of inactivated vaccines, compared with a booster of inactivated vaccine or ZF2001. The results demonstrated that boosting with bivalent Delta-Omicron BA.1 vaccine greatly promoted the neutralizing activity of the sera to all tested SARS-CoV-2 variants. Therefore, the Delta-Omicron chimeric RBD-dimer vaccine is a feasible booster for those with prior vaccination of COVID-19 inactivated vaccines.

description: Abstract

The evolutionary pathways of social-ecological systems are marked by periods of structural continuity interspersed with convulsive change. Climate change, social disruption, economic breakdown, financial collapse, nuclear confrontation, or pandemics might all cause systemic global shocks in the coming decades. The ongoing COVID-19 epidemic is a real-time example of a break in historical continuity. Deep institutional and cultural upheavals, on the other hand, may quickly bring in more robust forms of global Civilization. These realistic scenarios call for scenario studies to focus on discontinuous futures, a requirement that has not been satisfied effectively. Several issues, including gradualist conceptions of change, scientific reluctance, the allure of quantitative tractability, and embeddedness in governmental processes, have rendered standard scenario analysis unsuitable for the task.

V1 orientation plasticity is explained by broadly tuned feedforward inputs and intracortical sharpening

description: Orientation adaptation and perceptual learning change orientation tuning curves of V1 cells. Adaptation shifts tuning curve peaks away from the adapted orientation, reduces tuning curve slopes near the adapted orientation, and increases the responses on the far flank of tuning curves. Learning an orientation discrimination task increases tuning curve slopes near the trained orientation. These changes have been explained previously in a recurrent model (RM) of orientation selectivity. However, the RM generates only complex cells when they are well tuned, so that there is currently no model of orientation plasticity for simple cells. In addition, some feedforward models, such as the modified feedforward model (MFM), also contain recurrent cortical excitation, and it is unknown whether they can explain plasticity. Here, we compare plasticity in the MFM, which simulates simple cells, and a recent modification of the RM (MRM), which displays a continuum of simple-to-complex characteristics. Both pre- and postsynaptic-based modifications of the recurrent and feedforward connections in the models are investigated. The MRM can account for all the learning- and adaptation-induced plasticity, for both simple and complex cells, while the MFM cannot. The key features from the MRM required for explaining plasticity are broadly tuned feedforward inputs and sharpening by a Mexican hat intracortical interaction profile. The mere presence of recurrent cortical interactions in feedforward models like the MFM is insufficient; such models have more rigid tuning curves. We predict that the plastic properties must be absent for cells whose orientation tuning arises from a feedforward mechanism.

description: We propose a hybrid architecture composed of a fully convolutional network (FCN) and a Dempster-Shafer layer for image semantic segmentation. In the so-called evidential FCN (E-FCN), an encoder-decoder architecture first extracts pixel-wise feature maps from an input image. A Dempster-Shafer layer then computes mass functions at each pixel location based on distances to prototypes. Finally, a utility layer performs semantic segmentation from mass functions and allows for imprecise classification of ambiguous pixels and outliers. We propose an end-to-end learning strategy for jointly updating the network parameters, which can make use of soft (imprecise) labels. Experiments using three databases (Pascal VOC 2011, MIT-scene Parsing and SIFT Flow) show that the proposed combination improves the accuracy and calibration of semantic segmentation by assigning confusing pixels to multi-class sets.

description: We study the dynamics of surface waves on a semi-toroidal ring of water that is excited by vertical vibration. We create this specific fluid volume by patterning a glass plate with a hydrophobic coating, which confines the fluid to a precise geometric region. To excite the system, the supporting plate is vibrated up and down, thus accelerating and decelerating the fluid ring along its toroidal axis. When the driving acceleration is sufficiently high, the surface develops a standing wave, and at yet larger accelerations, a traveling wave emerges. We also explore frequency dependencies and other geometric shapes of confinement.

description: Following receptor-mediated uptake into endocytic vesicles and escape from the endosome, adenovirus is transported by cytoplasmic dynein along microtubules to the perinuclear region of the cell. How motor proteins are recruited to viruses for their own use has begun to be investigated only recently. We review here the evidence for a role for dynein and other motor proteins in adenovirus infectivity. We also discuss the implications of recent studies on the mechanism of dynein recruitment to adenovirus for understanding the relationship between pathogenic and physiological cargo recruitment and for the evolutionary origins of dynein-mediated adenovirus transport.

A Sequence of Degree One Vassiliev Invariants for Virtual Knots

description: For ordinary knots in R3, there are no degree one Vassiliev invariants. For virtual knots, however, the space of degree one Vassiliev invariants is infinite dimensional. We introduce a sequence of three degree one Vassiliev invariants of virtual knots of increasing strength. We demonstrate that the strongest invariant is a universal Vassiliev invariant of degree one for virtual knots in the sense that any other degree one Vassiliev invariant can be recovered from it by a certain natural construction. To prove these results, we extend the based matrix invariant introduced by Turaev for virtual strings to the class of singular virtual knots with one double-point.

description: The evolution between Fermi liquid and non-Fermi-liquid states in correlated electron systems has been a central subject in condensed matter physics because of the coupled intriguing magnetic and electronic states. An effective pathway to explore the nature of non-Fermi liquid behavior is to approach its phase boundary. Here we report a crossover from non-Fermi liquid to Fermi-liquid state in metallic CaRuO3 through ionic liquid gating induced protonation with electric field. This electronic transition subsequently triggers a reversible magnetic transition with the emergence of an exotic ferromagnetic state from this paramagnetic compound. Our theoretical analysis reveals that hydrogen incorporation plays a critical role in both the electronic and magnetic phase transitions via structural distortion and electron doping. These observations not only help understand the correlated magnetic and electronic transitions in perovskite ruthenate systems, but also provide novel pathways to design electronic phases in correlated materials.

Fiduciaries in a commercial context
Creators: name: Wright, David Malcolm
Publisher: name: University of British Columbia
Year: 2012

description: At present the law of fiduciary obligations is at a crossroads in Canada. An expansionist approach advocates recourse to this doctrine whenever a remedy is desired. The opposing argument, which perceives the fiduciary obligation in a traditional way, suggests that the fiduciary relationship is only the highest in a series of ever increasing standards of honesty required between parties. A brief examination of these contending positions will lead to the important question of permitting this equitable doctrine to operate within the parameters of a commercial context. The courts have traditionally been reluctant to extend general equitable doctrines into the commercial world. The underlying reasons for this disinclination will be sought. If any of these reasons are found to contain any justifiable concerns, alternatives to the total exclusion of the fiduciary relationship will be sought. The methodology for this thesis is clear; it is the close analytical examination of cases to decide in which direction the law should develop and what have been the points of departure for this area of law. This emphasis upon the past and future of the law of fiduciaries within the commercial context must be complemented with a detailed examination of the present Australian and Canadian legal positions. Particular attention must be paid to any test suggested by the recent caselaw for the determination of the presence of a fiduciary relationship. Finally the various remedies available to the court upon the determination that a fiduciary duty has been breached needs to be examined, as the various remedies which may be ordered can have differing consequences, particularly upon third parties, especially when the fiduciary relationship is within a commercial context.

The Labor Market Returns to For-Profit Higher Education: Evidence for Transfer Students

description: This study examines the labor market gains for students who enrolled at for-profit colleges after beginning their postsecondary education in community college. We use student level administrative record data from college transcripts, Unemployment Insurance earnings data, and progression data from the National Student Clearinghouse across full entry cohorts of community college students in two statewide systems between 2001 and 2006. We calculate the wage gains to attainment across different student transfer patterns. We find significant wage penalties to transfer to a for-profit college instead of a public or private nonprofit college. This earnings gap between higher education sectors is consistent but varies in size across subsamples of students. Importantly, it is only identifiable with a sufficient time window across which enrollment and earnings data are available. Students in for-profit colleges have lower opportunity costs in terms of foregone earnings while enrolled in college, but these do not sufficiently compensate for lower earnings growth post-college.

A Context for Mozart's French Ariettes: The Wendling Family and Friedrich Schiller's Kabale und Liebe
Creators: name: Corneilson, Paul
Publisher: name: Current Musicology
Year: 2006

description: This essay examines Mozart's relationship to the Wendling family and the French ariettes he wrote during his visit to Mannheim. Through documen-tary evidence we glimpse the underside of court life, involving an affair between Elisabeth Augusta Wendling and Elector Palatine Carl Theodor. Six years after Mozart's visit, Friedrich Schiller's Kabale und Liebe was performed at the Mannheim National Theater in 1784. The goal of the essay is first to draw connections between Mozart and the Wendlings, and second to consider Schiller's fictional Luisa Miller, her father, and mother-a family possibly modeled on the Wendlings.

description: We propose a new classifier based on Dempster-Shafer (DS) theory and a convolutional neural network (CNN) architecture for set-valued classification. In this classifier, called the evidential deep-learning classifier, convolutional and pooling layers first extract high-dimensional features from input data. The features are then converted into mass functions and aggregated by Dempster's rule in a DS layer. Finally, an expected utility layer performs set-valued classification based on mass functions. We propose an end-to-end learning strategy for jointly updating the network parameters. Additionally, an approach for selecting partial multi-class acts is proposed. Experiments on image recognition, signal processing, and semantic-relationship classification tasks demonstrate that the proposed combination of deep CNN, DS layer, and expected utility layer makes it possible to improve classification accuracy and to make cautious decisions by assigning confusing patterns to multi-class sets.

description: Multipath TCP (MPTCP) extends traditional TCP to enable simultaneous use of multiple connection endpoints at the source and destination. MPTCP has been under active development since its standardization in 2013, and more recently in February 2020, MPTCP was upstreamed to the Linux kernel. In this paper, we provide the first broad analysis of MPTCPv0 in the Internet. We probe the entire IPv4 address space and an IPv6 hitlist to detect MPTCP-enabled systems operational on port 80 and 443. Our scans reveal a steady increase in MPTCP-capable IPs, reaching 9k+ on IPv4 and a few dozen on IPv6. We also discover a significant share of seemingly MPTCP-capable hosts, an artifact of middleboxes mirroring TCP options. We conduct targeted HTTP(S) measurements towards select hosts and find that middleboxes can aggressively impact the perceived quality of applications utilizing MPTCP. Finally, we analyze two complementary traffic traces from CAIDA and MAWI to shed light on the real-world usage of MPTCP. We find that while MPTCP usage has increased by a factor of 20 over the past few years, its traffic share is still quite low.
