description: We consider the structure of self-gravitating marginally stable accretion disks in galactic centers in which a small fraction of the disk mass has been converted into proto-stars. We find that proto-stars accrete gaseous disk matter at prodigious rates. Mainly due to the stellar accretion luminosity, the disk heats up and geometrically thickens, shutting off further disk fragmentation. The existing proto-stars however continue to gain mass by gas accretion. As a results, the initial mass function for disk-born stars at distances R ~ 0.03-3 parsec from the super-massive black hole should be top-heavy. The effect is most pronounced at around R ~ 0.1 parsec. We suggest that this result explains observations of rings of young massive stars in our Galaxy and in M31, and predict that more of such rings will be discovered.

description: The model of production decision making for the expected utility maximizing firm under output price uncertainty is applied to a panel Pennsylvania dairy operators. The model generalized duality implemented in this paper has the advantage of generating a system of supply and variable factor demand functions that consistently account for the presence of output price risk. The application to Pennsylvania dairy operators indicates that output price risk measured by the second and third moments of individual operators' historical output price series is not an important factor in production decision making. In addition to not maximizing expected utility, these operators are not expected profit maximizers.

description: We compute the electromagnetic response and corresponding forces between two silver nanowires. The wires are illuminated by a plane wave which has the electric field vector perpendicular to the axis of the wires, insuring that plasmonic resonances can be excited. We consider a nontrivial square cross section geometry that has dimensions on the order of $0.1 λ$, where $λ$ is the wavelength of the incident electromagnetic field. We find that due to the plasmonic resonance, there occurs great enhancement of the direct and mutual electromagnetic forces that are exerted on the nanowires. The Lippman-Schwinger volume integral equation is implemented to obtain solutions to Maxwell's equations for various $λ$ and separation distances between wires. The forces are computed using Maxwell's stress tensor and numerical results are shown for both on and off resonant conditions.

description: The neoclassical paradigm has proven to be a rich approach for evaluating a variety of issues for individual and social decision-making. However, an increasing body of literature suggests that actual behavior systematically violates the neoclassical utility model. This paper reviews a number of alternative models for decision-making. Results from the literature show several examples of apparently "irrational" behavior that can be explained in terms of these alternative motivations. The paper also extends the received literature by examining in some detail the implications of one such model which is based on the psychological feeling of ambivalence. The paper demonstrates that ambivalence has the potential for explaining the appearance of intransitive choices, the use of rules of thumb in decision-making and the large discrepancies between stated willingness-to-pay and willingness-to-accept, all of which have been observed in various settings. There are potentially great rewards from innovative research that expands the neoclassical paradigm to incorporate additional motivational factors in decision-making.

description: Statistics based privacy-aware recommender systems make suggestions more powerful by extracting knowledge from the log of social contacts interactions, but unfortunately, they are static. Moreover, advice from local experts effective in finding specific business categories in a particular area. We propose a dynamic recommender algorithm based on a lazy random walk that recommends top-rank shopping places to potentially interested visitors. We consider local authority and topical authority. The algorithm tested on FourSquare shopping data sets of 5 cities in Indonesia with k-steps of 5,7,9 of (lazy) random walks and compared the results with other state-of-the-art ranking techniques. The results show that it can reach high score precisions (0.5, 0.37, and 0.26 respectively on precision at 1, precision at 3, and precision at 5 for k=5). The algorithm also shows scalability concerning execution time. The advantage of dynamicity is the database used to power the recommender system; no need to be very frequently updated to produce a good recommendation.

(2001), and using as variability measure that introduced by these authors. The results are puzzling. Assuming an isotropic-equivalent peak luminosity, as done by Reichart et al. (2001), a correlation is still found, but it is less relevant, and inconsistent with a power law as previously reported. Assuming as peak luminosity that corrected for GRB beaming for a subset of 16 GRBs with known beaming angle, the correlation becomes little less significant.

description: The failure to allow for significant crop quality effects in a partial-equilibrium model can lead to misleading inferences about the price, output and welfare implications of air quality improvements. It has been observed that air pollutants such as ozone, sulphur dioxide, and nitrogen dioxide affect the yield and quality of many crops. The economic benefit from improving air quality in crop producing regions has been measured using a partial-equilibrium approach which accounts only for supply shifting yield effects. It is shown that a yield-effect only model will underestimate output increases and benefits from an air quality improvement when commodity quality improvements as well as yield increases are forthcoming.

description: Along with the proliferation of Artificial Intelligence (AI) and Internet of Things (IoT) techniques, various kinds of adversarial attacks are increasingly emerging to fool Deep Neural Networks (DNNs) used by Industrial IoT (IIoT) applications. Due to biased training data or vulnerable underlying models, imperceptible modifications on inputs made by adversarial attacks may result in devastating consequences. Although existing methods are promising in defending such malicious attacks, most of them can only deal with limited existing attack types, which makes the deployment of large-scale IIoT devices a great challenge. To address this problem, we present an effective federated defense approach named FDA3 that can aggregate defense knowledge against adversarial examples from different sources. Inspired by federated learning, our proposed cloud-based architecture enables the sharing of defense capabilities against different attacks among IIoT devices. Comprehensive experimental results show that the generated DNNs by our approach can not only resist more malicious attacks than existing attack-specific adversarial training methods, but also can prevent IIoT applications from new attacks.
Vancouver Sun Run In Training clinics : an ordinal severity outcome measure and model of associated risk factors for running related pain
Creators: name: Ryan, Michael Bernard
Publisher: name: University of British Columbia
Year: 2009

description: This study determined the feasibility of implementing a severity outcome measure for the classification of running related pain, in addition to constructing a multivariate model of associated risk factors for injury in novice runners. Throughout the Greater Vancouver Metropolitan Area, 421 participants responded in 29 separate In Training clinics. Subjects, on average, self-selected their running experience as limited with average physical fitness, average competitive motive and at least vestigial symptoms from a previous injury. Participants in this 13-week training program were surveyed during the 6th and 12th week of the In Training clinics' 13-week duration. Questionnaire items included a VAS scale for indication of degree of rehabilitation from prior injury, physical fitness, competitive motive, weekly distance, running frequency and running experience. The Training Function Score is designed to quantify, using an ordinal scale, function limitations that result from running injuries. Subjects also indicated whether they were "currently experiencing an injury as a result of injury". Overall, 36.1% of subjects experienced an injury during the training program. Univariate regression showed degree of rehabilitation, physical fitness, competitive motive and weekly distance as significantly associated with injury. Multivariate results, however, indicate only degree of rehabilitation while physical fitness accounts for 25.4% of the explained variation in the severity outcome measure. Pratt analysis further shows that 90.1% of that explained variation is accounted for by degree of rehabilitation only. Initial psychometric characteristics demonstrate outcome measured ability to discriminate injured from non-injured (uninjured = 82.91, injured = 64.56 and clinically injured = 46.29*; significant difference p<.001) and evaluate severity (significant (p<.011), regression association with severity outcome measure and increasing subjective definition of injury scale). Moderately sedentary individuals commencing a running program for the first time should be cautious of the affect prior history of injury has toward re-injury. This study suggests that an outcome measure for generalized running injuries is possible with respect to discriminating injured from non-injured runners, as well as evaluating the severity of those injuries. While such an outcome measure for general running injuries is feasible, proper validation procedures and methodology must be established before such a scale is used formally.
Analytical realization of finite-size scaling for Anderson localization: Is there transition in the 2D case?

description: Roughly half of numerical investigations of the Anderson transition are based on consideration of an associated quasi-1D system and postulation of one-parameter scaling for the minimal Lyapunov exponent. If this algorithm is taken seriously, it leads to unumbiguous prediction of the 2D phase transition. The transition is of the Kosterlitz-Thouless type and occurs between exponential and power law localization (Pichard and Sarma, 1981). This conclusion does not contradict numerical results if the raw data are considered. As for interpretation of these data in terms of one-parameter scaling, such interpretation is inadmissible: the minimal Lyapunov exponent does not obey any scaling. A scaling relation is valid not for minimal, but for some effective Lyapunov exponent, whose dependence on parameters is determined by scaling itself. If finite-size scaling is based on the effective Lyapunov exponent, existence of the 2D transition becomes not definite, but still rather probable. Interpretation of the results in terms of the Gell-Mann -- Low equation is also given.

description: Through the last decade, cold atmospheric plasma (CAP) has emerged as an innovative therapeutic option for cancer treatment. Recently, we have set up a potentially safe atmospheric pressure plasma jet device that displays antitumoral properties in a preclinical model of cholangiocarcinoma (CCA), a rare and very aggressive cancer emerging from the biliary tree with few efficient treatments. In the present study, we aimed at deciphering the molecular mechanisms underlying the antitumor effects of CAP towards CCA both in an in vivo and in vitro context. In vivo, using subcutaneous xenografts into immunocompromised mice, CAP treatment of CCA induced DNA lesions and tumor cell apoptosis, as evaluated by 8-oxoguanine and cleaved caspase-3 immunohistochemistry, respectively. Analysis of the tumor microenvironment showed changes in markers related to macrophage polarization. In vitro, incubation of CCA cells with CAP-treated culture media (i.e. plasma-activated media, PAM) led to a dose response decrease in cell survival. At molecular level, CAP treatment induced double-strand DNA breaks, followed by an increased phosphorylation and activation of the cell cycle master regulators CHK1 and p53, leading to cell cycle arrest and cell death by apoptosis. In conclusion, CAP is a novel therapeutic option to consider for CCA in the future.

description: Metasurfaces have appeared as a versatile platform for miniaturized functional nonlinear optics due to their design freedom in tailoring wavefronts. The key factor that limits its application in functional devices is the low conversion efficiency. Recently, dielectric metasurfaces governed by either high-quality factor modes (quasi-bound states in the continuum) or Mie modes, enabling strong light-matter interaction, have become a prolific route to achieve high nonlinear efficiency. Here, we demonstrate both numerically and experimentally an effective way of spatial nonlinear phase control by using the Pancharatnam-Berry phase principle with a high third harmonic conversion efficiency of $10^{-4}$ $1/W^2$. We find that the magnetic Mie resonance appears to be the main contributor to the third harmonic response, while the contribution from the quasi-bound states in the continuum is negligible. This is confirmed by a phenomenological model based on coupled anharmonic oscillators. Besides, our metasurface provides experimentally a high diffraction efficiency (80-90%) in both polarization channels. We show a functional application of our approach by experimentally reconstructing an encoded polarization-multiplexed vortex beam array with different topological charges at the third harmonic frequency with high fidelity. Our approach has the potential viability for future on-chip nonlinear signal processing and wavefront control.

description: Commercial bank loans to New York farmers are significantly overestimated in the reported USDA statistics due to out-of-state lending and reporting of some agribusiness loans as agricultural loans by New York State banks. Correcting for this distortion lowers the 1978-84 average New York agricultural credit market share held by banks from 36 to 24 percent. As deregulation allows more interstate banking activity, the overestimate of agricultural loan volume in states with money center banks and the corresponding underestimate of loan levels and market shares in nonmoney center states could cause increased distortion of state level farm debt statistics.
Observations of Rapid Disk-Jet Interaction in the Microquasar GRS 1915+105

description: We present evidence that ~ 30 minute episodes of jet formation in the Galactic microquasar GRS 1915+105 may sometimes entirely be a superposition of smaller, faster phenomena. We base this conclusion on simultaneous X-ray and infrared observations in July 2002, using the Rossi X-ray Timing Explorer and the Palomar 5 meter telescope. On two nights, we observed quasi-periodic infrared flares from GRS 1915+105, each accompanied by a set of fast oscillations in the X-ray light curve (indicating an interaction between the jet and accretion disk). In contrast to similar observations in 1997, we find that the duration of each X-ray cycle matches the duration of its accompanying infrared flare, and we observed one instance in which an isolated X-ray oscillation occurred at the same time as a faint infrared "subflare" (of duration ~ 150 seconds) superimposed on one of the main flares. From these data, we are able to conclude that each X-ray oscillation had an associated faint infrared flare and that these flares blend together to form, and entirely comprise, the ~ 30 minute events we observed. Part of the infrared emission in 1997 also appears to be due to superimposed small flares, but it was overshadowed by infrared-bright ejections associated with the appearance of a sharp "trigger" spike in each X-ray cycle that were not present in 2002. We also study the evolution of the X-ray spectrum and find significant differences in the high energy power law component, which was strongly variable in 1997 but not in 2002. Taken together, these observations reveal the diversity of ways in which the accretion disk and jet in black hole systems are capable of interacting and solidify the importance of the trigger spike for large ejections to occur on ~ 30 minute timescales in GRS 1915+105.

description: Although energy substitution in U.S. manufacturing has been studied in great depth at the national level, little attention has been paid to the regional level. However, regions may differ in their use of energy for a variety of reasons. The main objective of this study is to estimate region-specific demands for energy using a dynamic model for two-digit SIC Code manufacturing sectors. We derive own and cross-price elasticities for energy for different regions and we compare them. We, thus, provide information which has implications for a region specific energy policy.
Higher derivative scalar-tensor theory from the spatially covariant gravity: a linear algebraic analysis

description: We investigate the ghostfree scalar-tensor theory with a timelike scalar field, with derivatives of the scalar field up to the third order and with the Riemann tensor up to the quadratic order. We build two types of linear spaces. One is the set of linearly independent generally covariant scalar-tensor monomials, the other is the set of linearly independent spatially covariant gravity monomials. We argue that these two types of linear space are isomorphic to each other in the sense of gauge fixing/recovering procedures. We then identify the subspaces in the spatially covariant gravity, which are spanned by linearly independent monomials built of the extrinsic and intrinsic curvature, the lapse function as well as their spatial derivatives, up to the fourth order in the total number of derivatives. The vectors in these subspaces, i.e., spatially covariant polynomials, automatically propagate at most three degrees of freedom. As a result, their images under the gauge recovering mappings are automatically the subspaces of scalar-tensor theory that propagate up to three degrees of freedom as long as the scalar field is timelike. The mappings from the spaces of spatially covariant gravity to the spaces of scalar-tensor theory are encoded in the projection matrices, of which we also derived the expressions explicitly. Our formalism and results can be useful in deriving the generally covariant higher derivative scalar-tensor theory without ghost(s).

description: An interregional competition model of the U.S. apple industry is constructed. This model includes the consumer products of fresh apples, applesauce and apple juice. The validation of the model showed that it did a good job of estimating consumer's quantity demanded and prices and a reasonable job of estimating utilization. This model was used to study the effects of transportation cost changes on the industry in the short- and intermediate run. The total production and consumption levels changed by moderate amounts with changing transport costs while the utilization of a region's crop was quite sensitive to such changes.

description: We study the influence of the regular component of the Galactic magnetic field (GMF) on the arrival directions of ultra-high energy cosmic rays (UHECRs). We find that, if the angular resolution of current experiments has to be fully exploited, deflections in the GMF cannot be neglected even for E=10^20 eV protons, especially for trajectories along the Galactic plane or crossing the Galactic center region. On the other hand, the GMF could be used as a spectrograph to discriminate among different source models and/or primaries of UHECRs, if its structure would be known with sufficient precision. We compare several GMF models introduced in the literature and discuss for the example of the AGASA data set how the significance of small-scale clustering or correlations with given astrophysical sources are affected by the GMF. We point out that the non-uniform exposure to the extragalactic sky induced by the GMF should be taken into account estimating the significance of potential (auto-)correlation signals.

It investigates the concept of “human” and asks whether the concept of human has an essence or is best understood by the idea of family resemblance. It asks whether DNA is the essence of humanity and concludes that it is not and that humanity is best understood using family resemblance involving a range of attributes common to humans. It concludes the fetus does not have the range of attributes that would make it human.

description: I report the analysis of B-->h+h'- decays (where h and h' denote K or pi), in 180 pb-1 of proton-antiproton collisions at s**0.5= 1.96 TeV, with the CDF II detector at the Tevatron Collider. A B-->h+h'- signal was reconstructed at a hadron collider for the first time, in the sample collected by the dedicated trigger on long-lived decays. With about 900 signal events, we observed the new mode Bs-->K+K-, and we measured its branching fraction relative to the B0-->K+pi- mode: (f_s/f_d)*BR(Bs-->K+K-)/BR(B0-->K+pi-)=0.46 +/- 0.08 (stat.) +/- 0.07 (syst.); we also measured the CP-violating decay-rate asymmetry for the B0-->K+pi- mode: ACP=-0.013 +/- 0.078 (stat.) +/- 0.012 (syst.). Since we did not find evidence for rarer modes, we set the following 90% C.L. upper limits on the decay rates: (f_s/f_d)*BR(Bs-->K-pi+)/BR(B0-->K+pi-)<0.08 and BR(Bs-->pi+pi-)/BR(Bs-->K+K-)< 0.05 that are greatly improved with respect to current world averages.

One-dimensional itinerant ferromagnets with Heisenberg symmetry and the ferromagnetic quantum critical point

description: We study one-dimensional itinerant ferromagnets with Heisenberg symmetry near a ferromagnetic quantum critical point. It is shown that the Berry phase term arises in the effective action of itinerant ferromagnets when the full SU(2) symmetry is present. We explicitly demonstrate that dynamical critical exponent of the theory with the Berry term is $z=2 +{\rm O}(ε^2)$ in the sense of $ε$ expansion, as previously discovered in the Ising limit. It appears, however, that the universality class at the interacting fixed point is not the same. We point out that even though the critical theory in the Ising limit can be obtained by the standard Hertz-Millis approach, the Heisenberg limit is expected to be different. We also calculate the exact electron Green functions $G(x,t=0)$ and $G(x=0,t)$ near the transition in a range of temperature, which can be used for experimental signatures of the associated critical points.

description: This paper compares two policies which can be used for multiplexing the traffic of a number of players of a First Person Shooter game. A network scenario in which a number of players share an access network has been simulated, in order to compare the policies in terms of a subjective quality estimator. The first policy, namely timeout, achieves higher bandwidth savings, while the second one, period, introduces less delay and jitter. The results show that the difference in terms of QoE is only significant when the number of players is small. Thus, in order to make the correct decision, the concrete network scenario and the characteristics of the router would have to be considered in each case, taking into account the estimation of the subjective quality that can be expected.

description: Compliant environments can mediate interactions between mechanically active cells like fibroblasts. Starting with a phenomenological model for the behaviour of single cells, we use extensive Monte Carlo simulations to predict non-trivial structure formation for cell communities on soft elastic substrates as a function of elastic moduli, cell density, noise and cell position geometry. In general, we find a disordered structure as well as ordered string-like and ring-like structures. The transition between ordered and disordered structures is controlled both by cell density and noise level, while the transition between string- and ring-like ordered structures is controlled by the Poisson ratio. Similar effects are observed in three dimensions. Our results suggest that in regard to elastic effects, healthy connective tissue usually is in a macroscopically disordered state, but can be switched to a macroscopically ordered state by appropriate parameter variations, in a way that is reminiscent of wound contraction or diseased states like contracture.

description: 3D printing offers fascinating possibilities for the production of X-ray phantoms for general (projective) radiography up to CT applications. While in 2D phantoms different attenuations can be realized by different absorption lengths, CT phantoms require materials with different mass density and/or different effective atomic number. In FDM (fused deposition modeling) printing, mass density depends on packing density of solid structures. Common printing parameters, however, result in filling ratios < 100%, and thus lower density negatively affecting reproducibility of phantoms, x-ray attenuation and Hounsfield Units in CT, and thus contrasts. As a consequence, printing parameters need to be optimized and controlled to result in maximum solid density. In SLA (Stereolithography) printing parameters do not influence density, and can only be set manually in one of the printers used (Anycubic Photon). In this project 41 kinds of materials consisting of filaments and resins were printed with different kinds of printers (Utimaker2+, Anycubic Photon, Formlabs Form 2 and Connex3). The optimal printing parameters for optimal printing quality and optimal filling ratio of 29 kinds of materials for FDM printer were measured respectively. An X-ray phantom was designed and printed out, and it was used for measuring Hounsfield Units (HU) of 41 kinds of materials by CT scanning.Materials most suitable for mimicking soft tissues and bone in radiographic phantoms could be identified.

Quantum protocols for anonymous voting and surveying

description: We describe quantum protocols for voting and surveying. A key feature of our schemes is the use of entangled states to ensure that the votes are anonymous and to allow the votes to be tallied. The entanglement is distributed over separated sites; the physical inaccessibility of any one site is sufficient to guarantee the anonymity of the votes. The security of these protocols with respect to various kinds of attack is discussed. We also discuss classical schemes and show that our quantum voting protocol represents a N-fold reduction in computational complexity, where N is the number of voters.

Postural and movement adaptations by individuals with a unilateral below-knee amputation during gait initiation
Creators: name: Tokuno, Craig Daisuke
Publisher: name: University of British Columbia
Year: 2009

description: Gait initiation, the transition from upright stance to steady state gait, requires the asymmetrical use of the two lower limbs. The initial stepping limb, called the lead leg, is mainly used to generate forward thrust, while the non-stepping, trailing limb is initially responsible for the generation of forward propulsion and the maintenance of body stability. For individuals with a unilateral below-knee amputation (BKA), this unequal sharing of responsibilities poses a potential conflict, as the prosthetic limb is known to have limitations in both stability and propulsion. Because the magnitude of this effect may differ depending upon the roles of each limb, the study hypothesized that individuals with a unilateral below-knee amputation would undergo unique postural and movement adaptations depending on the choice of the leading limb. Eleven individuals with a unilateral BKA and eleven control subjects were recruited for this study. From a standing position, each individual initiated gait at three step length conditions (+0%, +25%, and +50% of preferred step length). Half of the trials were initiated with the right limb, while the other half were initiated with the left. It was found that the amputees underwent postural and movement adaptations due to the presence of the prosthetic limb. The amputees required more time to initiate gait, applied a smaller magnitude of peak propulsive force, and exhibited a smaller displacement of the center of pressure. The magnitude of these changes was, however, found to be dependent upon the choice of the leading limb, as greater compensations were observed during the prosthetic trail limb condition. Three conclusions were made from this study. First, the prolonged task duration allowed the amputees to apply a larger horizontal impulse, such that they were able to fully compensate for the decreased propulsive ability of the prosthetic limb. Second, the slower rate of initiation and the decrease in displacement of the center of pressure allowed the amputees to remain more stable throughout the entire task. Finally, it appeared that the role of the trailing limb had a greater impact during gait initiation and thus, leading with the prosthetic limb resulted in fewer postural and movement adaptations.
A complex adaptive systems approach to the kinetic folding of RNA

description: The kinetic folding of RNA sequences into secondary structures is modeled as a complex adaptive system, the components of which are possible RNA structural rearrangements (SRs) and their associated bases and base pairs. RNA bases and base pairs engage in local stacking interactions that determine the probabilities (or fitnesses) of possible SRs. Meanwhile, selection operates at the level of SRs; an autonomous stochastic process periodically (i.e., from one time step to another) selects a subset of possible SRs for realization based on the fitnesses of the SRs. Using examples based on selected natural and synthetic RNAs, the model is shown to qualitatively reproduce characteristic (nonlinear) RNA folding dynamics such as the attainment by RNAs of alternative stable states. Possible applications of the model to the analysis of properties of fitness landscapes, and of the RNA sequence to structure mapping are discussed.

description: There is a wide collection of journal articles and academic discourse on family firms’ social capital. However, the focus on the comprehensive synthesis of the collections is limited. The lack of efforts to synthesize the issue of family firms’ social capital focuses on emerging economies further limiting the utility of the literature. Despite the various differences between family firms in developed and emerging economies; no attempt was undertaken to separate the different insights and issues between the two different contexts. Thus, this article focusing on emerging economies is an attempt to bridge this gap in the literature. Consequently, to provide a review on researches that focus on family firm’s social capital in emerging economies, Bibliometric analysis is used to provide quantitative insights. The qualitative insights are generated from a systematic literature review. Journal articles are retrieved as data to achieve these objectives. The time frame of literature extraction is from 1960 to the year 2018. Data is extracted from WOS and Scopus indexed database yielding 288 documents. After manual scrutinizing the content, only 31 (10.8%) of the cited literature is on the family firm social capital related issue. The paper finds that there is an increasing trend in the number of family firms’ social capital study in the context of the emerging economies. The highly cited articles are published by Deephouse and Jaskiewicz (2013) in the Journal of Management Studies with 179 citations, and Khavul et al. (2009) in the Entrepreneurship: Theory and Practice with 140 citations. The findings provide a collection of evidence about the focus, variables, and theories used from credible sources of the family firms’ social capital studies.
