On The Problem of Particle Production in c=1 Matrix Model
Creators: name: Mukhopadhyay, Partha

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We reconsider and analyze in detail the problem of particle production in the time dependent background of $c=1$ matrix model where the Fermi sea drains away at late time. In addition to the moving mirror method, which has already been discussed in hep-th/0403169 and hep-th/0403275, we describe yet another method of computing the Bogolubov coefficients which gives the same result. We emphasize that these Bogolubov coefficients are approximately correct for small value of the deformation parameter. We also study the time evolution of the collective field theory stress-tensor with a special point-splitting regularization. Our computations go beyond the approximation of the previous treatments and are valid at large coordinate distances from the boundary at a finite time and up-to a finite coordinate distance from the boundary at late time. In this region of validity our regularization produces a certain singular term that is precisely canceled by the collective field theory counter term in the present background. The energy and momentum densities fall off exponentially at large distance from the boundary to the values corresponding to the static background. This clearly shows that the radiated energy reaches the asymptotic region signaling the space-time decay.

Other modifications include minor changes in the text and addition of one reference. Version accepted for publication in JHEP

description: Humans have an exquisite sense of touch which robotic and prosthetic systems aim to recreate. We developed algorithms to create neuron-like (neuromorphic) spiking representations of texture that are invariant to the scanning speed and contact force applied in the sensing process. The spiking representations are based on mimicking activity from mechanoreceptors in human skin and further processing up to the brain. The neuromorphic encoding process transforms analog sensor readings into speed and force invariant spiking representations in three sequential stages: the force invariance module (in the analog domain), the spiking activity encoding module (transforms from analog to spiking domain), and the speed invariance module (in the spiking domain). The algorithms were tested on a tactile texture dataset collected in 15 speed-force conditions. An offline texture classification system built on the invariant representations has higher classification accuracy, improved computational efficiency, and increased capability to identify textures explored in novel speed-force conditions. The speed invariance algorithm was adapted to a real-time human-operated texture classification system. Similarly, the invariant representations improved classification accuracy, computational efficiency, and capability to identify textures explored in novel conditions. The invariant representation is even more crucial in this context due to human imprecision which seems to the classification system as a novel condition. These results demonstrate that invariant neuromorphic representations enable better performing neurorobotic tactile sensing systems. Furthermore, because the neuromorphic representations are based on biological processing, this work can be used in the future as the basis for naturalistic sensory feedback for upper limb amputees.

description: The reference crop evapotranspiration (ET0) was estimated for three locations of Bangladesh using the standard Penman-Monteith (P-M) method as recommended by the Food and Agriculture Organization of the United Nations (FAO). The same was also estimated using four other emperical methods and compared with the standard method. The regression equations developed were evaluated with independent data sets. The superiority order were found as: FAO temperature, Radiation, Hargreaves and pan evaporation, respectively. It is revealed from the study that the regression equation developed herein with FAO temperature method can be used to estimate ET0 more accurately than the original FAO temperature method, as well as regression equations with other methods.

description: An effort was made to study the rice processing technology, energy and labour utilization in commercial rice processing mills for parboiled rice. For this purpose 20 selected rice mills of Gapalpur and Parbotipur upazilas were visited and relevant data were collected through field survey conducted during the period from November 2001 to February 2002. Average total energy used in the rice mills was estimated about 708.5 kWh/t. Of the total energy used, biomass energy comprised 91.74% (650.0 kWh/t), electridal 7.81% (55.3 kWh/t) and manual 0.45% (3.2 kWh/t). The average electrical energy used for a huller and a vibrating sieve was 36.7 kWh/t, whereas average energy used for lighting, fans and water pumps were 6.4, 0.8, 11.4 kWh/t, respectively. Locally made steel boilers and drum boilers were used with husk as fuel. Husk Was required at the rate of 150.- 155 kg husk/t paddy for double steaming. Manual labour utilized in the rice mills averaged 42.77 'manhat (3.19 kWh/t). Maximum energy was required for carrying paddy, rice and other by-products in bags - or baskets (14.48 man-hr/t), followed by manual separation of broken rice (12,11 man-hr/t), mechanical separation of head rice (5.35 man-hr/t), bagging and unbagging (4.04 man-hr/t), drying (4.04 man-hr/t), loading and unloading soaking tank (1.4 man-hr/t), feeding boiler furnace with husk (0.85 man-hr/t), and weighing (0.54 man-hr/t). The amount of labour required depended mainly on the walking distance, frequency of movement and the load being carried at a time. Wide variations were observed in carrying distances in 20 rice mills. Minimizing the carrying distances, through proper planning of the rice mill layout, could reduce the labour requirement for carrying. Excessive loads were carried on the head resulting in health hazards of the workers. The use of bucket trolley for carrying steamed paddy and two-wheel trolley for bags of paddy and rice would irriprove the work efficiency of the labourers. The number of labourers employed in a rice mill depended on the volume of paddy processed per day (mill capacity). Both male and female labourers were employed in the rice mills and gender-wise job preferences were observed.

A comparative assessment of the effectiveness of a peer versus a counselor in presenting a date rape prevention intervention program to college students

description: The study examined the perceived effectiveness of a peer (college senior) versus a professional counselor, as assessed through the Counselor Rating Form (CRF), in presenting the Date Rape Prevention (DRP) video in a sample of undergraduate college students. The three dimensions of Effectiveness that were assessed were Attractiveness, Expertness, and Trustworthiness. Further, an Overall Effectiveness rating combining the assessment of the three dimensions was determined. Four hypotheses postulated that the mean CRF Expertness, Attractiveness, Trustworthiness, and Overall Effectiveness scores for subjects grouped by pre-DRP video information that its presenter's status was a peer would be significantly higher than that for subjects told the presenter was a professional counselor. An experimental, randomized between-subject research design was employed. Data used in hypotheses testing were elicited from 186 undergraduate college students enrolled in six Introductory Psychology courses. Students were divided into two groups, 90 of whom were told the presenter in the DRP video was a peer and 96 of whom were told the presenter in the DRP video was a professional counselor. Data were obtained through the CRF and the Participant Information Inventory (PII). The CRF developed by A. Barak & M. B. LaCrosse in 1975, was used to assess the presenter's effectiveness. The PII was developed by the author for this study to gather demographic information about its participants, participants' personal involvement with date rape and rating of the DRP video. The t-test was used in testing each hypothesis. The standard for significance was p $\le$.05. The findings in this study indicate that subjects who were told the presenter in the DRP video was a peer did not perceive the presenter's "expertness," "attractiveness," "trustworthiness," or "overall effectiveness" differently than did subjects who were told the presenter's status was a professional counselor. Therefore, each of the four study hypotheses was not confirmed. These findings seem to warrant the conclusion that campus intervention programs that are designed to educate undergraduate college students about date rape and teach them behaviors that could lead to the prevention of the problem can be presented as effectively by a peer as they can by a professional counselor.

description: Previous studies show that “… nearly one in four freshmen gain at least 5% of their body weight, an average of about 10 pounds, during their first semester” (Freshman 15). Most previous studies have looked at how much weight gain actually occurs between men and women. This study is aimed at tackling the reasons for unhealthy eating behaviors in first year students at The University of British Columbia. The study looked at how varying factors between first year residence areas at UBC were associated with barriers to healthy eating. 150 questionnaires were administered to first year residents’ living in Totem Park, Place Vanier, and Walter Gage. Barriers of time, money, and perceived control over healthy eating behaviors were the main focus. We used ANOVA and 2-sample t-test to conduct the statistical analyses. The data suggests that residents from Place Vanier and Totem Park felt the barrier of time less than residents in Walter Gage. Students with a meal plan felt, on average, more deterred from healthy options due to financial pressures and unappealing healthy options provided by the dining hall. Finally students residing in Walter Gage felt more perceived control of healthy eating choices than Place Vanier and Totem Park residents.

description: Small-scale irrigation schemes constructed for poverty reduction in developing countries are mostly managed by Water User Associations (WUAs). Users contributions in terms of labour towards resource maintenance is critical in sustaining the schemes. The amount of labour contributed depends on many factors, including users perceptions of the governance of WUAs and users willingness to cooperate in collective activities. In this paper we assess the effects of users governance perceptions and cooperativeness on maintenance contributions in northern Ghana. We use household survey data to create indicators of six governance dimensions, and estimate user s cooperativeness through lab-in-the-field experiments. OLS and Tobit regressions are used to respectively assess determinants of labour contributions and cooperativeness. We find that positive governance perceptions and cooperativeness generally affect labour contributions positively. Specifically, perceptions of transparency & cooperation affect labour contributions directly; and accountability and sustainable use both influence labour contributions directly and indirectly as mediated by the cooperativeness of users. Conflict management however has a negative impact on cooperativeness, and through that on labour contributions. We conclude that although better governance perceptions generally influence labour contributions to the maintenance of irrigation schemes positively, different dimensions differ in their direct as well as indirect contributions.

The need for university-provided services by a sample of students with disabilities at the state-supported universities in Pennsylvania

Publisher: name: American University
Year: 2023

description: The purpose of this study was to ascertain the needs for twenty designated university-provided services by students with disabilities affiliated with the Pennsylvania Office of Vocational Rehabilitation (OVR) at the fourteen state-supported universities in the Commonwealth. The data used to address the study's three research questions were the 212 OVR students' expressed need for each of 20 selected university-provided services as indicated on the five-alternative extent-of-need response continuum (none, low, moderate, strong, very strong) of the Special Students Services Inventory (SSSI). The chi square statistic was used in comparing need according to student's gender and type of disability. The.05 level was the criterion for statistical significance. The results showed that the preponderance of disabled students (over 53%) had "low" or "no" need for 18 of the 20 selected university services. For 19 of 20 services, the modal frequency was in the "none" alternative and for no service did a majority of the students indicate "strong" or "very strong" need. The strongest need of OVR students in general was for services pertaining to financial aid advisement, academic support, and next step placement assistance. The services least needed were related to medically prescribed diets, library aids, and special communication equipment. These least-needed services seemed to be associated more to students with specific disability types than to all students with disabilities. The need for the 20 services by students classified by gender differed significantly for one service. This seemed to warrant the conclusion that no differentiation needs to be made in the provision of a program of campus services for disabled students because of their gender. Students with certain types of disabilities reported a stronger need for 12 of the 20 services than did students with disabilities in general. This finding supports the conclusion that certain services must be tailored to the disability type more so than to students with disabilities in general.

description: For the Chilean economy, the blueberry and apple sector have an important role regarding production and employment. To remain competitive in the export supply chain, farmers require to adjust to more efficient and productive systems. One important way to increase agricultural productivity is through the introduction of improved agricultural technologies and management systems. In particular, the study focuses on how levels of innovation, measured by complexity and investments requirements of the adopted technologies, relates to innovative behavior and complying with social responsibility practices, as two indicators of the farmer's behavior towards innovation. A typology of farmers with different technological levels was constructed based on multivariate techniques, according to the adoption of seven technologies. Findings showed three clusters: cluster I of high technology farms (32.2%), cluster II of farms with complex and low-cost technologies (27%), and cluster III of farms with low technology (40.68%). Within the cluster, it was identified that cluster I, farmers have a positive attitude toward innovation and the highest SR implementation rates. The farmers from cluster I were similar from cluster II in structural variables, but they significantly differ in innovative behavior attitudes. Cluster III, significantly differ with cluster I in structural variables, behavioral variables, and SR practices. The results showed the heterogeneity among farmers and the complexity of the adoption decision-making process shading lights on policy design to enhance innovation, research and technology transfer among farmers Acknowledgement :

description: An effective way of assessing the potential of any crop is to estimate the profitability growing it in a single year, but this ignores the impacts of previous crops. The top five crops by seeded area in southern Manitoba are canola, soybeans, spring wheat, grain corn and oats. The yearly return from these crops grown in various five year rotations is the focus of this study. This study uses 5 year average relative yield response values, a measure of the impact that one crop has on the yield of next seeded crop. Rotation options from the 5 top crops are analyzed. Returns using 5 year average yields and prices, adjusted by the estimated impacts of previous crops, are calculated and ranked to determine the top 10 performing rotations. Historical prices were applied to the top ten budgets to see if the rotation ranks survived over time as prices varied. The top rotation, corn and soybeans, remained optimal for all but 3 years in the 13 examined. Continuous cropping, even with high earning corn, is significantly less profitable than crops grown in rotation.

description: In classical spin systems with two largely different inherent time scales, the configuration of the fast spins almost instantaneously follows the slow-spin dynamics. We develop the emergent effective theory for the slow-spin degrees of freedom and demonstrate that this generally includes a topological spin torque. This torque gives rise to anomalous real-time dynamics. It derives from the holonomic constraints defining the fast-spin configuration space and is given in terms of a topological charge density which becomes a quantized homotopy invariant when integrated.

description: The scaling properties of self-avoiding walks on a d-dimensional diluted lattice at the percolation threshold are analyzed by a field-theoretical renormalization group approach. To this end we reconsider the model of Y. Meir and A. B. Harris (Phys. Rev. Lett. 63:2819 (1989)) and argue that via renormalization its multifractal properties are directly accessible. While the former first order perturbation did not agree with the results of other methods, we find that the asymptotic behavior of a self-avoiding walk on the percolation cluster is governed by the exponent nu_p=1/2 + epsilon/42 + 110epsilon^2/21^3, epsilon=6-d. This analytic result gives an accurate numeric description of the available MC and exact enumeration data in a wide range of dimensions 2<=d<=6.

description: During the last two decades, the Mexican dairy sector experienced important structural changes, especially after the implementation of the NAFTA agreement. In 2016, the Bank of Mexico observed that in milk market, the final prices tend to rise when input prices increase, however, they do not decrease when imput prices decrease. In this context, this study examines the degree of spatial and vertical price transmission between farm milk prices and international milk prices as well as between farm milk prices and retail milk prices, in order to assess the ef?ciency level of the Mexican and International dairy market. The ?ndings of this research provide contributions to decision makers and industry stake-holders: a unidirectional transmission of international milk prices to domestic milk prices and from farm price to retail price along with the existence of asymmetric price transmission which depends on whether milk prices are increasing or decreasing.

description: Suppression of anger has been associated with depression in both theoretical and empirical literature. Increased levels of anger experienced by depressed individuals could explain increased anger suppression found in this population. However, most studies have reported only comparable or lower levels of anger expression among depressed individuals, than found among nondepressed individuals. Studies of the marital interactions of depressed individuals have reported higher levels of anger expression in comparison to their nondepressed counterparts. Heightened levels of interpersonal dependence, common in depressed individuals, could account for greater suppression of anger. Interpersonal dependence, mediated by fear of expressing anger, is proposed to account for the observed relationship between depression and anger suppression. This study tested the hypothesis that the suppression of anger found in depressed individuals is accounted for to a greater extent by interpersonal dependence than by depression itself. Subjects included 33 clinically depressed married clients and 41 married community volunteers. The results indicate that levels of anger suppression correspond more directly to levels of interpersonal dependence than to levels of depression. The relationship of dependence to anger suppression is mediated by consequential fears of anger expression. Slightly different patterns of correspondence were found to exist within the marital dyad as compared to within other relationships. Heightened levels of anger experienced appear to account for the concurrent elevations in anger expressed and anger suppressed found in the marital interaction studies. Theoretical implications and suggestions for future research are included.

In the Brillouin zone (BZ), the sign of the Berry-curvature field's monopole charge is referred to as the chirality ($χ$) of the node, leading to the notion of chiral quasiparticles sourcing chiral currents, induced by internode scatterings proportional to the chiral anomaly. Here, we derive the generic form of the chiral conductivity when we have multifold nodes. Since the sum of all the monopole charges in the BZ is constrained to vanish, the nodes appear in pairs of $χ=\pm 1$. Hence, the presence of band-crossing degeneracies of order higher than two make it possible to have two distinct scenarios: the pair of conjugate nodes in question comprise bands of (1) the same pseudospin variety and exhibiting Berry-curvature profiles differing by an overall factor of $χ$, or (2) two distinct pseudospin representations. Covering these two possibilities, we apply our derived formula to semimetals harbouring triple-point (threefold-degenerate) and Rarita-Schwinger-Weyl (fourfold-degenerate) nodes, and show the resulting expressions for the conductivity featuring the chiral anomaly.

description: We study the magnetic properties of metallic GaMnAs. We calculate the effective RKKY interaction between Mn spins using several realistic models for the valence band structure of GaAs. We also study the effect of positional disorder of the Mn on the magnetic properties. We find that the interaction between two Mn spins is anisotropic due to spin-orbit coupling within both the so-called spherical approximation and in the more realistic six band model. The spherical approximation strongly overestimates this anistropy, especially for short distances between Mn ions. Using the obtained effective Hamiltonian we carry out Monte Carlo simulations of finite and zero temperature magnetization and find that, due to orientational frustration of the spins, non-collinear states appear in both valence band approximations for disordered, uncorrelated Mn impurities in the small concentration regime. Introducing correlations among the substitutional Mn positions or increasing the Mn concentration leads to an increase in the remnant magnetization at zero temperature and an almost fully polarized ferromagnetic state.

The relationship between self-report anger and depression
Creators: name: Goldman, Lee Alan
Publisher: name: American University
Year: 2023

description: Suppression of anger has been associated with depression in both theoretical and empirical literature. Increased levels of anger experienced by depressed individuals could explain increased anger suppression found in this population. However, most studies have reported only comparable or lower levels of anger expression among depressed individuals, than found among nondepressed individuals. Studies of the marital interactions of depressed individuals have reported higher levels of anger expression in comparison to their nondepressed counterparts. Heightened levels of interpersonal dependence, common in depressed individuals, could account for greater suppression of anger. Interpersonal dependence, mediated by fear of expressing anger, is proposed to account for the observed relationship between depression and anger suppression. This study tested the hypothesis that the suppression of anger found in depressed individuals is accounted for to a greater extent by interpersonal dependence than by depression itself. Subjects included 33 clinically depressed married clients and 41 married community volunteers. The results indicate that levels of anger suppression correspond more directly to levels of interpersonal dependence than to levels of depression. The relationship of dependence to anger suppression is mediated by consequential fears of anger expression. Slightly different patterns of correspondence were found to exist within the marital dyad as compared to within other relationships. Heightened levels of anger experienced appear to account for the concurrent elevations in anger expressed and anger suppressed found in the marital interaction studies. Theoretical implications and suggestions for future research are included.

description: Companies dealing with Artificial Intelligence (AI) models in Autonomous Systems (AS) face several problems, such as users' lack of trust in adverse or unknown conditions, gaps between software engineering and AI model development, and operation in a continuously changing operational environment. This work-in-progress paper aims to close the gap between the development and operation of trustworthy AI-based AS by defining an approach that coordinates both activities. We synthesize the main challenges of AI-based AS in industrial settings. We reflect on the research efforts required to overcome these challenges and propose a novel, holistic DevOps approach to put it into practice. We elaborate on four research directions: (a) increased users' trust by monitoring operational AI-based AS and identifying self-adaptation needs in critical situations; (b) integrated agile process for the development and evolution of AI models and AS; (c) continuous deployment of different context-specific instances of AI models in a distributed setting of AS; and (d) holistic DevOps-based lifecycle for AI-based AS.

description: Subsidies to promote tree plantations have been recently questioned because of potential negative social and environmental impact of the forestry industry. Quantitative evidence on the socioeconomic causal impacts of afforestation subsidies or of tree plantations is elusive, mainly due to data scarcity. We assess the overall impact of such a subsidy in Chile by using an original 20 years panel data set that includes small area estimates of poverty and relate it to the subsidy assignment at census-district scale. We show, with a battery of impact evaluation techniques, that forestry subsidies -on average- do, in fact, increase poverty. More specifically, using difference in difference with matching techniques, and instrumental variable approaches we show that there is an increment of about 2% in the poverty rate of treated (with subsidized tree plantations) localities. We also identify a causal mechanism by which tree plantations induce higher poverty, which is a negative effect on employment. Our research indicates the existence of negative welfare effects of the afforestation subsidy on local populations suggesting a reassessment of the distributional effects of the subsidy and the industry.

description: The Brazilian Amazon and Cerrado biomes have been subject to strong pressure from agricultural expansion over the past decades. It is frequently claimed that the associated tree cover loss was partly driven by land speculation. In the mid-2000s, the Brazilian government implemented an innovative policy regime to combat deforestation with a strong focus on the Amazon region. While there is solid evidence that the new environmental governance approach was effective in reducing Amazon forest loss, some research indicates that leakage effects have contributed to increasing land conversion in the Cerrado. In this paper, we contribute to investigating these hypotheses using land market data covering the period from 2001 to 2012. Based on land rent and hedonic valuation theory, we use a first difference panel regression analysis to decompose forestland prices into land rent, conversion costs, and speculative attributes. We then assess whether, where, and to what extent conservation policy shocks affect forestland prices over time. Our measures of speculation and conservation are significant in all our model specifications. Our findings suggest that land prices represent an indicator for spatially and temporally shifting land demand and related speculative behavior, and the presence of conservation policy leakage in Brazil.

description: We consider a scheme for on-demand teleportation of a dual-rail electron qubit state, based on single-electron sources and detectors. The scheme has a maximal efficiency of 25%, which is limited both by the shared entangled state as well as the Bell-state measurement. We consider two experimental implementations, realizable with current technology. The first relies on surface acoustic waves, where all the ingredients are readily available. The second is based on Lorentzian voltage pulses in quantum Hall edge channels. As single-electron detection is not yet experimentally established in these systems, we consider a tomographic detection of teleportation using current correlators up to (and including) third order. For both implementations we take into account environmental effects.

description: This paper analyzes the impact the Canadian Wheat Board (CWB) had on facilitating grain movements and utilizing terminal capacity from 2009/10 to 2015/16 in western Canada through econometric methods. We conduct an ex-post analysis on capacity utilization for every grain delivery station in western Canada controlling for distance to port, car spots, railway companies, and production. We use a CWB dummy variable and freight rates from Quorum Corporation to estimate capacity utilization before and after CWB abolishment. We analyze whether the CWB had an impact on terminal turnover ratios. We conclude the regulatory change in abolishing the CWB significantly reduced capacity utilization and delivery performance despite record production and implementation of ad hoc policies. Current regulatory changes regarding the Minimum Revenue Entitlement (MRE) could have similar outcomes on grain handling performance. Acknowledgement :
