description: Optimal dense coding using a partially-entangled pure state of Schmidt rank $\bar D$ and a noiseless quantum channel of dimension $D$ is studied both in the deterministic case where at most $L_d$ messages can be transmitted with perfect fidelity, and in the unambiguous case where when the protocol succeeds (probability $τ_x$) Bob knows for sure that Alice sent message $x$, and when it fails (probability $1-τ_x$) he knows it has failed. Alice is allowed any single-shot (one use) encoding procedure, and Bob any single-shot measurement. For $\bar D\leq D$ a bound is obtained for $L_d$ in terms of the largest Schmidt coefficient of the entangled state, and is compared with published results by Mozes et al. For $\bar D > D$ it is shown that $L_d$ is strictly less than $D^2$ unless $\bar D$ is an integer multiple of $D$, in which case uniform (maximal) entanglement is not needed to achieve the optimal protocol. The unambiguous case is studied for $\bar D \leq D$, assuming $τ_x>0$ for a set of $\bar D D$ messages, and a bound is obtained for the average $\lgl1/τ\rgl$. A bound on the average $\lglτ\rgl$ requires an additional assumption of encoding by isometries (unitaries when $\bar D=D$) that are orthogonal for different messages. Both bounds are saturated when $τ_x$ is a constant independent of $x$, by a protocol based on one-shot entanglement concentration. For $\bar D > D$ it is shown that (at least) $D^2$ messages can be sent unambiguously. Whether unitary (isometric) encoding suffices for optimal protocols remains a major unanswered question, both for our work and for previous studies of dense coding using partially-entangled states, including noisy (mixed) states.

description: The results of experiments on the formation of molecular hydrogen on low density and high density amorphous ice surfaces are analyzed using a rate equation model. The activation energy barriers for the relevant diffusion and desorption processes are obtained. The more porous morphology of the low density ice gives rise to a broader spectrum of energy barriers compared to the high density ice. Inserting these parameters into the rate equation model under steady state conditions we evaluate the production rate of molecular hydrogen on ice-coated interstellar dust grains.

Living with early stage Alzheimer’s disease : what helps, what hinders
Creators: name: Bowen-Roberts, Kathryn F.
Publisher: name: University of British Columbia
Year: 2009

description: It is only in the last 25 years that Alzheimer's disease has garnered much interest in the world of research. Most of this has been of a quantitative nature, focusing on etiology, treatment, genetics, characteristics, and behavioural aspects of the disease. The purpose of this study was to examine the increasingly salient but comparatively under-researched issue of Alzheimer's disease from the perspective of the affected individual. An exploratory study was conducted in the Lower Mainland area of British Columbia with 8 participants who had been diagnosed as having Alzheimer's disease, currently in the early stages. Purposeful sampling was used to recruit participants via referrals, personal contact, and networking. Using the qualitative approach of Critical Incident Technique, participants were interviewed individually twice and their accounts were examined. Specifically, the goal of this study was to enrich the understanding of the experience of living with early stage Alzheimer's disease by developing a set of categories describing those factors that help and hinder individuals' ability to live with their illness. Implications for counselling affected individuals and their families and directions for future research were discussed. It was concluded that the resulting categories can be utilised in numerous ways for those living with Alzheimer's disease as well as those working with them, both formally and informally.

description: A highly sensitive photodetection system with a detection limit of 1 photon/s was developed. This system uses a commercially available 200-mm-diameter silicon avalanche photodiode (APD) and an in-house-developed ultralow-noise readout circuit, which are both cooled to 77 K. When the APD operates at a low gain of about 10, it has a high-linearity response to the number of incident photons and a low excess noise factor. The APD also has high quantum efficiency and a dark current of less than 1 e/s at 77 K. This photodetection system will shorten the measurement time and enable higher spatial and wavelength resolution for near-field scanning optical microscopes.

description: The Kepler mission has provided a treasure trove of eclipsing binaries (EBs), observed at extremely high photometric precision, nearly continuously for several years. We are carrying out a survey of ~100 of these EBs to derive dynamical masses and radii with precisions of 3% or better. We use multiplexed near-infrared H band spectroscopy from the SDSS-III and -IV APOGEE instrument and optical spectroscopy from the HET High-Resolution Spectrograph to derive double-lined spectroscopic orbits and dynamical mass-ratios for the EB sample. This information is combined with Kepler photometry to derive orbital inclination, dynamical masses of the components, radii and temperatures. These measurements are directly applicable for benchmarking stellar models that are integrating the next generation of improvements, such as the magnetic suppression of convection efficiency, updated opacity tables, and fine-tuned equations of state. We selected our EB sample to include systems with low-mass ($M \lt 0.8 \; M_{\odot}$) primary or secondary components, many expected to populate the relatively sparse parameter space below $0.5 \; M_{\odot}$. In this paper, we describe our EB sample and the analysis techniques we are utilizing, and present masses and radii for two systems that inhabit particularly underpopulated regions of mass-radius-period space: KIC 2445134 and KIC 3003991. Our analysis of KIC 2445134 ($q=0.411 \pm 0.001$) yields masses and radii of $M_A = 1.29 \pm 0.03 \; M_{\odot}$, $M_B = 0.53 \pm 0.01 \; M_{\odot}$, $R_A = 1.42 \pm 0.01 \; R_{\odot}$, $R_B = 0.510 \pm 0.004 \; R_{\odot}$, and a temperature ratio of $T_B/T_A = 0.635 \pm 0.001$; our analysis of KIC 3003991 ($q=0.298 \pm 0.006$) yields $M_A = 0.74 \pm \; 0.04 M_{\odot}$, $M_B = 0.222 \pm \; 0.007 M_{\odot}$, $R_A = 0.84 \pm 0.01 \; R_{\odot}$, $R_B = 0.250 \pm 0.004 \; R_{\odot}$, and a temperature ratio of $T_B/T_A= 0.662 \pm 0.001$.

description: Success is the ultimate end that any organization is looking for, regardless of the nature of the organization. A variety of factors in occupational settings affect organizational success. Employees’ perception of fairness with regard to organizational practices can have an important implication on the success of the organization. The purpose of this study is to examine the influence of organizational justice on organizational success, monitoring the mediating role of organizational citizenship behavior. Primary data collected from a total of 328 Amhara Regional State Public Enterprises employees were used to test the proposed relationship between the constructs of the study. Correlation and multiple regression data analysis techniques were employed. Structural Equation Modeling was used to run a mediation analysis. Findings revealed that organizational justice has a significant positive effect on their success (β = 0.45, p < 0.01). The study also confirmed that organizational citizenship behavior has a statistically significant effect on organizational success (β = 0.308, p < 0.01). The finding of the mediation analysis indicated that organizational citizenship behavior partially mediates the relationship between organizational justice and success. Finally, the study recommends public enterprises promote organizational justice and citizenship behavior. Every organization faces difficulties in ensuring organizational success. Consequently, organizations pursued different strategies to ensure success. Some of them set out fair rules, regulations, and procedures to dispense goods, services, tasks, rewards, wages, organizational positions, opportunities, punishments, and roles among employees. Organizational justice plays an important role in ensuring a good perception of employees towards their organization. Therefore, justice perceptions stimulate employees to engage in extra-role behaviors towards their organization, enabling organizations to be more successful. Organizational citizenship behavior is an employee’s extra-role behavior used to make organizations successful. This paper, therefore, assessed the effect of organizational justice and citizenship behavior on organizational success. The paper also determines the mechanisms of how employees’ justice perceptions affect organizational success. The study revealed that organizational citizenship behavior and organizational justice affect organizational success. It also revealed that organizational citizenship behavior partially mediates the relationship between organizational justice and success.

description: We propose a regime-switching model that allows demand to respond asymmetrically to upward and downward advertising changes. With the introduction of a smooth transition function, the model features smooth rather than abrupt parameter changes between regimes. We apply the model to nonalcoholic beverage data in the United States for 1974 through 2005 to investigate asymmetric advertising response. Results indicate that a decrease in milk advertising had a more profound impact on milk demand than an increase did. An increase in milk advertising had no impact on milk demand, but a decrease could have an own-advertising elasticity up to 0.049.

Moreover, we discuss the role and the relevance of saturation and recombination effects in our approach, in comparison with other recent suggestions.

description: Most technology adoption research has focused on crops. Primary data were used to determine differences in management practices among two groups of Oklahoma cow-calf producers based on herd size and cattle income dependence. Significant differences were noted between two groups of producers (smaller operations with less dependence on cattle versus larger with more dependence on cattle) in 79% of the management practices examined. Logit models determined factors influencing the probability of adopting 17 recommended practices. Important factors included the firm goal to choose practices that reduce labor, income dependence on cattle, human capital, and size of operation.

description: Breeders of purebred bulls have multiple avenues to market their bulls, including consignment at public auctions associated with performance tests. Purebred breeders often have the opportunity to withdraw bulls that are eligible to sell in these auctions. We examine sales data from a public auction held in conjunction with a performance bull test in Tucumcari, NM, to gain insights on breeder decisions to withdraw bulls prior to entering the sales ring. Specifically, we use a binary logit model to identify relevant characteristics that affect a breeder’s decision to withdraw a sale eligible bull from the auction.

description: We study emergent dynamics of the Lohe hermitian sphere(LHS) model which can be derived from the Lohe tensor model \cite{H-P2} as a complex counterpart of the Lohe sphere(LS) model. The Lohe hermitian sphere model describes aggregate dynamics of point particles on the hermitian sphere $\bbh\bbs^d$ lying in ${\mathbb C}^{d+1}$, and the coupling terms in the LHS model consist of two coupling terms. For identical ensemble with the same free flow dynamics, we provide a sufficient framework leading to the complete aggregation in which all point particles form a giant one-point cluster asymptotically. In contrast, for non-identical ensemble, we also provide a sufficient framework for the practical aggregation. Our sufficient framework is formulated in terms of coupling strengths and initial data. We also provide several numerical examples and compare them with our analytical results.

description: Recently, the twist angle between adjacent sheets of stacked van der Waals materials emerged as a new knob to engineer correlated states of matter in two-dimensional heterostructures in a controlled manner, giving rise to emergent phenomena such as superconductivity or correlated insulating states. Here,we use an ab initio based approach to characterize the electronic properties of twisted bilayer MoS2. We report that, in marked contrast to twisted bilayer graphene, slightly hole-doped MoS2 realizes a strongly asymmetric px-py Hubbard model on the honeycomb lattice, with two almost entirely dispersionless bands emerging due to destructive interference. We study the collective behavior of twisted bilayer MoS2 in the presence of interactions, and characterize an array of different magnetic and orbitally-ordered correlated phases,which may be susceptible to quantum fluctuations giving rise to exotic, purely quantum, states of matter.

description: A major concern with immigrants coming into the United States is that they adversely affect domestic workers through job competition and wage depression.We study the displacement and wage reduction effects of immigrants in California vegetable production, which is labor intensive, and 95% of the farmworkers in California are immigrants. Our findings show that this concern is not valid in vegetable production because the addition of one new immigrant displaces only 0.0123 domestic workers, and wage reduction is inconsequential. But one immigrant worker increases the vegetable production by $23,457 and augments the productivity of skilled workers, material inputs, and capital by $11,729.

description: We study the measurement-induced non-Gaussian operation on the single- and two-mode \textit{Gaussian} squeezed vacuum states with beam splitters and on-off type photon detectors, with which \textit{mixed non-Gaussian} states are generally obtained in the conditional process. It is known that the entanglement can be enhanced via this non-Gaussian operation on the two-mode squeezed vacuum state. We show that, in the range of practical squeezing parameters, the conditional outputs are still close to Gaussian states, but their second order variances of quantum fluctuations and correlations are effectively suppressed and enhanced, respectively. To investigate an operational meaning of these states, especially entangled states, we also evaluate the quantum dense coding scheme from the viewpoint of the mutual information, and we show that non-Gaussian entangled state can be advantageous compared with the original two-mode squeezed state.

description: The cattle industry batch markets animals in pens. Because of this, animals within any one pen can be both underfed and overfed. Thus, there is a production inefficiency associated with batch marketing. We simulate the value of sorting animals through weight and ultrasound measurements from original pens into smaller alternative marketing groups. Sorting exploits the production inefficiency and enables cattle feeding enterprises to avoid meat quality discounts, capture premiums, more efficiently use feed resources, and increase returns. The value of sorting is between $15 and $25 per head, with declining marginal returns as the number of sort groups increases.

Year: 2005

description: A Monte Carlo simulation exploring uncertainties in standard stellar evolution theory on the red giant branch of metal-poor globular clusters has been conducted. Confidence limits are derived on the absolute V-band magnitude of the bump in the red giant branch luminosity function (M_v,b) and the excess number of stars in thebump, R_b. The analysis takes into account uncertainties in the primordial helium abundance, abundance of alpha-capture elements, radiative and conductive opacities, nuclear reaction rates, neutrino energy losses, the treatments of diffusion and convection, the surface boundary conditions, and color transformations. The uncertainty in theoretical values for the red giant bump magnitude varies with metallicity between +0.13/-0.12 mag at [Fe/H] = -2.4 and +0.23/-0.21 mag at [Fe/H] = -1.0$. The dominant sources of uncertainty are the abundance of the alpha-capture elements, the mixing length, and the low-temperature opacities. The theoretical values of M_v,b are in good agreement with observations. The uncertainty in the theoretical value of R_b is +/-0.01 at all metallicities studied. The dominant sources of uncertainty are the abundance of the alpha-capture elements, the mixing length, and the high-temperature opacities. The median value of R_b varies from 0.44 at [Fe/H] = -2.4$ to 0.50 at [Fe/H] = -1.0. These theoretical values for R_b are in agreement with observations.

description: We use epsilon-cooling, adjusting at will the order a^2 corrections to the lattice action, to study the parameter space of instantons in the background of non-trivial holonomy and to determine the presence and nature of constituents with fractional topological charge at finite and zero temperature for SU(2). As an additional tool, zero temperature configurations were generated from those at finite temperature with well-separated constituents. This is achieved by "adiabatically" adjusting the anisotropic coupling used to implement finite temperature on a symmetric lattice. The action and topological charge density, as well as the Polyakov loop and chiral zero-modes are used to analyse these configurations. We also show how cooling histories themselves can reveal the presence of constituents with fractional topological charge. We comment on the interpretation of recent fermion zero-mode studies for thermalized ensembles at small temperatures.

description: This paper quantifies advances of the Kansas Agricultural Experiment Station (KAES) wheat breeding program for two time periods: (1) 1911 to 2006 and (2) 1977 to 2006. Using multiple regression, increases in yields of wheat varieties grown in Kansas are quantified, holding growing conditions and other improvements in productivity constant. Differences in KAES variety yields and those released by other public and private breeders are quantified. During the ‘‘new age’’ of wheat breeding (1977–2006), wheat breeding alone is found to have increased yields by 6.182 bushels per acre, or an average increase of 0.206 bushels per year.

description: BL Lac objects are an extreme type of active galactic nuclei (AGNs) that belong to the largest population of $γ$-ray sources: blazars. This class of AGNs shows a double-bumped spectral energy distribution that is commonly described in terms of a synchrotron self-Compton (SSC) emission process, whereas the low-energy component that dominates their emission between the infrared and the X-ray band is tightly connected to the high-energy component that peaks in the $γ$-rays. Two strong connections that link radio and mid-infrared emission of blazars to the emission in the $γ$-ray band are well established. They constitute the basis for associating $γ$-ray sources with their low-energy counterparts. We searched for a possible link between X-ray and $γ$-ray emissions for the subclass of BL Lacs using all archival Swift/XRT observations combined with Fermi data for a selected sample of 351 sources. Analyzing $\sim$2400 ks of Swift/XRT observations that were carried out until December 2018, we discovered that above the $γ$-ray flux threshold $F_γ\approx3\times10^{-12}\,\rm{erg}\,\rm{cm}^{-2}\,\rm{s}^{-1}$, 96\% of all \emph{Fermi} BL Lacs have an X-ray counterpart that is detected with signal-to-noise ratio higher than 3. We did not find any correlation or clear trend between X-ray and $γ$-ray fluxes and/or spectral shapes, but we discovered a correlation between the X-ray flux and the mid-infrared color. Finally, we discuss on a possible interpretation of our results in the SSC framework.

description: The decline in agricultural output over the years and the subsequent pervasive food crisis in most of Africa have motivated governments and international organizations to develop a variety of strategies, policy alternatives and programs aimed at promoting agricultural production and food security. Many of these strategies have been conceived and implemented by international organizations, and in some cases the strategies have fail to address the root cause of failure of the agricultural sector to perform to its potential. Therefore, this field study uses scenario analysis to engage key players in the agriculture industry to identify causes of Angola’s loss of production capacity over the years, the factors needed to revitalize the agricultural-led economy, factors that can help stabilize the agricultural sector and conditions required for the development and coordination of the food supply chain in Angola. The framework provided in the paper was based on an evaluation of perceptions of future demand for locally produced agricultural products; the country’s supply response capability; the role of the informal and formal markets; infrastructure needs; and the development of formal supply chains for domestic and export markets. The methodology used was an adaptation of a methodology used in Industry Strategic Planning and Coordination, and the Technological Demands Determination by Prospective Analysis. The study revealed that in spite of its high resource endowment, Angola will first need to address institutional and structural agricultural development constraints and develop systems that allow better coordination of development efforts among institutions, before it is able to produce food for export markets. The development priority for the next five years includes creating conditions that stimulate local production, help the country produce enough to become food self sufficient, and gradually reduce food imports. Nevertheless, the production for import substitution should not preclude efforts towards targeting export niche markets.

description: In high mass X-ray binaries (HMXBs), an accreting compact object orbits a high mass star which loses mass through a dense and inhomogeneous wind. Using the compact object as an X-ray backlight, the time variability of the absorbing column density in the wind can be exploited in order to shed light on the micro-structure of the wind and obtain unbiased stellar mass loss rates for high mass stars. We explore the impact of clumpiness on the variability of the column density with a simplified wind model. In particular, we focus on the standard deviation of the column density and the characteristic duration of enhanced absorption episodes, and compare them with analytical predictions based on the porosity length. We identified the favorable systems and orbital phases to determine the wind micro-structure. The coherence time scale of the column density is shown to be the self-crossing time of a clump in front of the compact object. We provide a recipe to get accurate measurements of the size and of the mass of the clumps, purely based on the observable time variability of the column density. The coherence time scale grants direct access to the size of the clumps while their mass can be deduced separately from the amplitude of the variability. If it is due to unaccreted passing-by clumps, the high column density variations in some HMXBs requires high mass clumps to reproduce the observed peak-to-peak amplitude and coherence time scales. These clump properties are hardly compatible with the ones derived from first principles. Alternatively, other components could contribute to the variability of the column density: larger orbital scale structures produced by a mechanism still to be identified, or a dense environment in the immediate vicinity of the accretor such as an accretion disk, an outflow or a spherical shell around the magnetosphere of the accreting neutron star.

 Pishkash II (41°04.986 ʹ N, 20°31.560 ʹ E, 701 m a.s.l.), 28 September 2005, 4♂ ad., including one that was sexually active, netted while entering a small cave in a limestone gorge. The cave could be used for night-roosting and/or swarming based on what is known from the other Balkan regions (Schunger et al. 2004).
 The present locality of this species is one of the southernmost on the Balkan Peninsula and demonstrates its wider occurrence in the region, where it has previously been considered to be very local and rare (Paunović et al. 2003). Its nearest previously known localities are in eastern Macedonia (Kryštufek and Petkovski 2003) and central Greece (Hanák et al. 2001). Barbastella barbastellus has been recorded in all of the Balkan countries (Paunović et al. 2003; Pavlinić et al. 2010; Pašić et al. 2013), including Montenegro (A. Rachwald, unpubl. data).

Instability of Tachyon Supertube in Type IIA Godel Spacetime

description: We study the tachyon supertube probes in a type IIA supergravity background which is a stringy-like Gödel spacetime and contains closed timelike curve. In the case of small value of $f$, which is a parameter of the background, we use the Minahan-Zwiebach tachyon action to obtain a single regular tube solution and argue that the tube is a BPS D2-brane. However, we find that the fluctuation around the tube configuration has a negative-energy mode. This means that the tachyon supertube, despite being a BPS configuration, develops an instability in the pathological spacetime with closed timelike curve which violates the causality.

A survey of school psychology practice in British Columbia
Creators: name: Merx, Tanya M.
Publisher: name: University of British Columbia

description: Major questions regarding the roles of school psychologists and delivery system reforms have appeared in the school psychology literature over the last of couple decades (Benson & Hughes, 1985; Fagan & Wise, 2000; Jackson, Balinky, & Lambert, 1993; Jerrell, 1984; Lacayo, Morris, & Sherwood, 1981; Reschly, 1988; Reschly & Wilson, 1995; Roberts & Rust, 1994). Consequently, many U.S. national survey studies have been conducted (Anderson, Cancelli, & Kratochwill, 1984; Benson & Hughes, 1985; Curtis, Chesno Grier, Walker Abshier, Sutton, & Hunley, 2002; Fischer, Jenkins, & Crumbley, 1986; Hutton & Dubes, 1992; Lacayo et al., 1981; Reschly & Wilson, 1995; Smith, 1984; Smith, Clifford, Hesley, & Leifgren, 1992; Stinnett, Havey, & Oehler-Stinnett,1994). However, there is little current empirical research on the roles and functions of school psychologists in British Columbia. Research is needed to help assess the state of the art in this province and explain what psychologists are doing. The profession of school psychology is unregulated in B.C. and so it is possible that persons practicing in the schools have a variety of training and offer a variety of services. Further, there is much existing uncertainty regarding the future path of the profession (Benson, 2002). The purpose of this study is to explore the job roles and functions of practicing school psychologists in B.C. and to examine the impact of various personal, professional, and job-site characteristics and external influences on job roles and functions. Survey methodology (N=42) was used with five select follow-up interviews for a sample of school psychologists around the province. Results revealed that the majority of respondents held a masters degree in school or educational psychology. Although respondents allocated a majority of their professional time to the role of assessment, school psychologists occupied a broad number of roles and desired to increase their time allocated to the other roles of interventions, consultation, counseling, and research and evaluation. Further, job roles were impacted by the number of students and schools served by psychologists, and psychologists' supervisors' field of specialization.

description: Using Euler's formula for a network of polygons for 2D case (or polyhedra for 3D case), we show that the number of dynamic\textit{\}degrees of freedom of the electric field equals the number of dynamic degrees of freedom of the magnetic field for electrodynamics formulated on a lattice. Instrumental to this identity is the use (at least implicitly) of a dual lattice and of a (spatial) geometric discretization scheme based on discrete differential forms. As a by-product, this analysis also unveils a physical interpretation for Euler's formula and a geometric interpretation for the Hodge decomposition.

description: We study the effect of the boundary on a system of weakly interacting bosons in one dimension. It strongly influences the boson density which is completely suppressed at the boundary position. Away from it, the density is depleted over the distances on the order of the healing length at the mean-field level. Quantum fluctuations modify the density profile considerably. The local density approaches the average one as an inverse square of the distance from the boundary. We calculate an analytic expression for the density profile at arbitrary separations from the boundary. We then consider the problem of localization of a foreign quantum particle (impurity) in the potential created by the inhomogeneous boson density. At the mean-field level, we find exact results for the energy spectrum of the bound states, the corresponding wave functions, and the condition for interaction-induced localization. The quantum contribution to the boson density gives rise to small corrections of the bound state energy levels. However, it is fundamentally important for the existence of a long-range Casimir-like interaction between the impurity and the boundary.
