description: This University of British Columbia (UBC) outdoor litter audit encompasses a preliminary understanding of the UBC outdoor litter problem. The audit was developed in consultation with the Social Ecological Economic Development Studies (SEEDS) sustainability program, UBC Municipal Services, and Dr. Zeina Baalbaki. It successfully investigated and determined the prevalence and composition of outdoor litter with relation to high traffic areas and proximity to waste receptacles. Through developing a litter monitoring plan, implementing an outdoor waste audit, and comprehensively analyzing waste composition and density data, the audit identified key sources of litter and generated realistic solutions. The litter audit, conducted on March 23rd, 2024, revealed multiple results. It identified that cigarettes, packaging wrappers, takeout items, and receipts made up 57% of all litter collected. It also showed that out of all litter collected, litter in a 1-meter radius of waste receptacles was 10 times denser (by number of items per square meter) than litter collected within 6 meters of the receptacle. Two monitoring plans, two solutions, and multiple recommendations were developed to address the litter areas of concern. The monitoring plans will act to collect necessary information on the impact of litter on stormwater quality, and to bolster university databases on litter prevalence, location, and composition. The solutions consisted of improving accessibility and efficacy of current disposal infrastructure relating to multi-streamed waste bins and cigarette receptacles. There are significant opportunities of growth to address UBC’s outdoor litter issue – integrating continued litter monitoring with pre-existing programs, increased accessibility of outdoor paper recycling, redesigning waste receptacle openings, and considering human interaction with waste receptacles. Given that UBC has not engaged in an outdoor litter audit before, continued litter monitoring will significantly improve data robustness which can better inform future waste management decisions.

description: Excerpts from the report Summary: Many firms are attempting to devise new methods of marketing fresh red meat that will overcome some of the inefficiencies and limitations of conventional practices. Widespread trade interest has been shown in the possibility of accomplishing desired improvements by removing fresh meat fabrication (such as, cutting into wholesale or retail cuts, boning, cubing, and grinding) and packaging work from retail stores to central processing plants. Freezing is generally regarded as the most practical method currently available for centrally processing the meat and still preserving its fresh qualities. During the last 25 years, extensive industry experience has been acquired in freezing packaged fresh red meats for specialized purposes. This experience has shown that fresh meat can be processed at any desired location with no appreciable change in quality or texture of meats, providing proper packaging and handling methods are employed. This report gives a general description of processing methods, equipment, packaging materials, and marketing channels that were being employed by various firms engaged in central prepackaging and freezing of fresh red meat products at the time of the study. Information was obtained from interviews with industry members and from observation of representative types of meat packaging and freezing operations.

description: We study entanglement in Valence-Bond-Solid state. It describes the ground state of Affleck, Kennedy, Lieb and Tasaki quantum spin chain. The AKLT model has a gap and open boundary conditions. We calculate an entropy of a subsystem (continuous block of spins). It quantifies the entanglement of this block with the rest of the ground state. We prove that the entanglement approaches a constant value exponentially fast as the size of the subsystem increases. Actually we proved that the density matrix of the continuous block of spins depends only on the length of the block, but not on the total size of the chain [distance to the ends also not essential]. We also study reduced density matrices of two spins both in the bulk and on the boundary. We evaluated concurrencies.

description: We try to improve the Thomas-Fermi model for the total energy and electron density of atoms and molecules by directly modifying the Euler equation for the electron density, which we argue is less affected by nonlocal corrections. Here we consider the simplest such modification by adding a linear gradient term to the Euler equation. For atoms, the coefficient of the gradient term can be chosen so that the correct exponential decay constant far from the nucleus is obtained. This model then gives a much improved description of the electron density at smaller distances, yielding in particular a finite density at the nucleus that is in good qualitative agreement with exact results. The cusp condition differs from the exact value by a factor of two. Values for the total energy of atomic systems, obtained by coupling parameter integration of the densities given by the Euler equation, are about as accurate as those given by very best Thomas-Fermi-Weizsacker models, and the density is much more accurate. Possible connections to orbital-free methods for the kinetic-energy functional in density functional theory are discussed.

description: It is widely recognized that human capital and skill development are significant determinants that could positively affect farmers performance and their disposition to adopt innovations. General education as well as specific agricultural education and training is argued as vital to overcoming development challenges in rural areas. More than 70 per cent of the people in Africa live in rural areas and depend on smallholder agriculture for food and livelihood. Yet majority of them are poor, illiterate and are faced with precarious food and nutrition insecurity. This study seeks to not only assess the impact of post-secondary education on economic outcomes (consumption expenditure and poverty), but also asses the returns to and distributional effects of post-secondary education among rural farmers in four countries (Ethiopia, Malawi, Nigeria and Tanzania). While using novel nationally representative panel data and a variety of estimation techniques, results are rather robust and indicate that post-secondary education significantly increases consumption expenditure by 12.5% in Tanzania and 27.6% in Ethiopia. Results further show that post-secondary education significantly reduces poverty by 42.5% in Malawi and 47.5% in Nigeria. Our findings are of policy relevance to most SSA countries currently grappling with rising urbanization, high youth unemployment, and acute skills shortage.

description: Let $K$ be a field of characteristic 0. Fix integers $r,d$ coprime with $r \geq 2$. Let $X_K$ be a smooth, projective, geometrically connected curve of genus $g \geq 2$ defined over K. Assume there exists a line bundle $L_K$ on $X_K$ of degree $d$. In this article we prove the existence of a stable locally free sheaf on $X_K$ with rank $r$ and determinant $L_K$. This trivially proves the $C_1$ conjecture in mixed characteristic for the moduli space of stable locally free sheaves of fixed rank and determinant over a smooth, projective curve.

Model-independent Distance Calibration and Curvature Measurement using Quasars and Cosmic Chronometers

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: We present a new model-independent method to determine the spatial curvature and to mitigate the circularity problem affecting the use of quasars as distance indicators. The cosmic-chronometer measurements are used to construct the curvature-dependent luminosity distance $D^{\rm cal}_{L}(Ω_{K},z)$ using a polynomial fit. Based on the reconstructed $D^{\rm cal}_{L}(Ω_{K},z)$ and the known ultraviolet versus X-ray luminosity correlation of quasars, we simultaneously place limits on the curvature parameter $Ω_{K}$ and the parameters characterizing the luminosity correlation function. This model-independent analysis suggests that a mildly closed Universe ($Ω_{K}=-0.918\pm0.429$) is preferred at the $2.1σ$ level. With the calibrated luminosity correlation, we build a new data set consisting of 1598 quasar distance moduli, and use these calibrated measurements to test and compare the standard $Λ$CDM model and the $R_{\rm h}=ct$ universe. Both models account for the data very well, though the optimized flat $Λ$CDM model has one more free parameter than $R_{\rm h}=ct$, and is penalized more heavily by the Bayes Information Criterion. We find that $R_{\rm h}=ct$ is slightly favoured over $Λ$CDM with a likelihood of $\sim57.7\%$ versus 42.3\%.

description: Can farmers adapt to climate change by altering weather conditions on their fields? We define the concept of "Micro-Climate Engineering" (MCE), where farmers change the effective temperatures on their crops by means of shading or heating, and document such implementation by California pistachio growers. With rising winter temperatures and declining winter chill portions, pistachio growers in California could face adverse climatic conditions within 20 years. Treating dormant trees with a chemical mix, acting as a shading technology, has shown to increase winter chill count to acceptable levels. Modeling a market with heterogeneous sub-climates, we run simulations to estimate potential gains from MCE in the year 2030 for California pistachio. Our results show an expected yearly welfare gain ranging between $1-4 billion. However, heterogeneous baseline climate creates clear winners and losers from this technology. Applying the concept of MCE more broadly, we point to its potential benefits in general as an adaptation technique, while also noting its potential for widening the global gap in climate change damage incidence, depending on heterogeneity in baseline climates, economic conditions, and market power.

description: Increasing population pressure in the rural areas of Sub-Saharan Africa causes degradation of communal lands, as well as increases in landless farmers. To promote the conservation based utilization of communal lands and increase the incomes of poor farmers, the Ethiopian government introduced a distribution program of the less-utilized communal lands to landless farmers. Although this policy is a novel approach to reducing population pressure while maintaining soil and water conservation, participation is not active enough in some areas. As such, this study shows the social norms for natural resource conservation of the communities affect the participation in the program. Using original farm household data, it estimates models for program participation determinants, especially the effects of social norms for conservation, represented by proportion of area enclosure, amount of activities for soil and water conservation, and evaluation by local government. The results show that the social norms for conservation affect program participation positively. They also show that the norms do not affect the farmers incomes, meaning norms directly influence participation. These results suggest the possibility of norm enhancement by extension works. Therefore, the sustainable utilization of communal lands would be more effective if it accompanies programs that improve social norms of villages.

description: Food habit is changing for most communities around the world. The factors causing those changes and their impacts, however, differs according to local specificities. The studies related to changes in the food basket composition shed light on changing demands and health conditions of the communities. While there are ample studies related to the topic of diet transition of indigenous population in developed countries, the literature void is dire for similar communities in developing countries especially in Asia. This paper studies the dynamics of the food basket composition of a highly marginalized indigenous community in the remote mid-hills of Nepal. The analysis is basically qualitative, supported by descriptive statistics based on panel data collected through household surveys in 2010 and 2015. Results show declining consumption of millet from own production and wild tubers. Rice, lentil and cooking oil is increasingly procured from the market. The results imply that the community is increasingly relying on non-traditional food items from the market; while the traditional food items cultivated or gathered from forest sees a declining trend. The study provides implications for line agencies and development organizations to devise suitable policy-programs aiming to improve the food security of such marginalized communities.

description: A superstructure can elicit versatile new properties of materials by breaking their original geometrical symmetries. It is an important topic in the layered graphene-like two-dimensional transition-metal dichalcogenides (TMDs), but its origin remains unclear. Using diamond-anvil cell techniques, synchrotron x-ray diffraction, x-ray absorption, and the first-principles calculations, we show that the evolution from the weak Van der Waals bonding to the Heisenberg covalent bonding between layers induces an isostructural transition in quasi-two-dimensional 1$\textit{T}$-type VSe$_2$ at high pressure. Furthermore, our results show that high-pressure induce a novel superstructure at 15.5 GPa, rather than suppress as it would normally, which is unexpected. It is driven by the Fermi surface nesting, enhanced by the pressure-induced distortion. The results suggest that the superstructure not only appears in the two-dimensional structure but also can emerge in the pressure-tuned three-dimensional structure with new symmetry and develop superconductivity.

description: Agrochemical expenditure is an important component of recent farming activities following the decreasing soil fertility. Yet, many contemporary studies have not attempted an evaluation of the impact of this expenditure on crop yield. This study uses primary observational data of 299 rural farmers gathered through a simple random sampling technique in Ghana to determine the impact of agrochemical expenditure on maize yield. The analysis is based on the Generalised Propensity Score matching technique; a continuous treatment causal inference model with many of the attractive properties of the standard propensity score matching. The results of the analysis show that agrochemical expenditure has a positive impact on maize yield after a minimum threshold. We also found this marginal factor productivity to be increasing at a decreasing rate after the rate of increase attains a maximum. Thus, the relationship between agrochemical expenditure and maize yield is nonlinear and this nonlinearity seems to be largely explained by the expenditure on mineral fertiliser. Consequently, we recommend that input credit schemes of government should be guided by this returns to expenditure dynamics in deciding optimal support packages to farmers. Acknowledgement :

description: Dielectric relaxation in disordered dielectric mixtures are presented by emphasizing the interfacial polarization. The obtained results coincide with and cause confusion with those of the low frequency dispersion behavior. The considered systems are composed of two phases on two-dimensional square and triangular topological networks. We use the finite element method to calculate the effective dielectric permittivities of randomly generated structures. The dielectric relaxation phenomena together with the dielectric permittivity values at constant frequencies are investigated, and significant differences of the square and triangular topologies are observed. The frequency dependent properties of some of the generated structures are examined. We conclude that the topological disorder may lead to the normal or anomalous low frequency dispersion if the electrical properties of the phases are chosen properly, such that for ``slightly'' {\em reciprocal mixture}--when $σ_1\ggσ_2$, and $ε_1

description: In electronic solids with strong spin-orbit interactions (SOIs), the spin and orbital degrees of freedom of an electron are quantum mechanically entangled, which may result in an exotic multipolar order instead of a conventional dipolar order such as a magnetic order. Such a higher-degree order is called "hidden order" because of difficulties in experimental detection. Moreover, the number of candidate compounds is limited, especially rare in d electron systems, in which an interplay between SOIs and Coulomb interactions is expected to cause rich physics. Here, we employ state-of-the-art synchrotron X-ray diffraction techniques on a high-quality single crystal to probe subtle symmetry breaking induced by a multipolar order. We unequivocally demonstrate that the double-perovskite Ba2MgReO6 exhibits successive transitions to quadrupolar and then dipolar orders upon cooling, which is consistent with a theory considering SOIs. Our findings are a significant step towards understanding the intriguing physics of multipoles realized by spin-orbit-entangled 5d electrons.

description: Of nearly 2.7 million farm sole proprietors filing tax returns in 1982, just 97,018 (4 percent) deducted soil and water conservation expenses and only 61,829 (2 percent) deducted land-clearing expenses. Each of these deductions averaged less than $1,100 per return on which they were claimed. Average tax savings were estimated to be from $177 to $246 for farmers claiming conservation expense deductions and from $220 to $280 for those deducting landclearing expenses. Although of considerable importance to individuals, these land improvement tax deductions were of minor importance to the farm sector, especially when contrasted to other tax provisions, such as the investment credit.

description: The reaction $γp \to π^0 π^0 p$ has been measured using the TAPS BaF$_2$ calorimeter at the tagged photon facility of the Mainz Microtron accelerator. Chiral perturbation theory (ChPT) predicts that close to threshold this channel is significantly enhanced compared to double pion final states with charged pions. In contrast to other reaction channels, the lower order tree terms are strongly suppressed in 2$π^0$ photoproduction. The consequence is the dominance of pion loops in the 2$π^0$ channel close to threshold - a result that opens new prospects for the test of ChPT and in particular its inherent loop terms. The present measurement is the first which is sensitive enough for a conclusive comparison with the ChPT calculation and is in agreement with its prediction. The data also show good agreement with a calculation in the unitary chiral approach.

Those which were in operation less than 5 years in 1980 created jobs at a net rate of 76 percent. Multi-establishment firms (called corporations in this report) accounted for about 68 percent of the net increase in nonmetro jobs during 1976-80. Small corporations created almost 14 percent of the new jobs and large corporations (those with 100 or more employees) created 54 percent.

description: We investigate, by experiments and numerical simulations, thermal activation processes of Josephson tunnel junctions in the presence of microwave radiation. When the applied signal resonates with the Josephson plasma frequency oscillations, the switching current may become multi-valued in a temperature range far exceeding the classical to quantum crossover temperature. Plots of the switching currents traced as a function of the applied signal frequency show very good agreement with the functional forms expected from Josephson plasma frequency dependencies on the bias current. Throughout, numerical simulations of the corresponding thermally driven classical Josephson junction model show very good agreement with the experimental data.

description: We study the temporal evolution of speckle patterns in transmission of short wave pulses through a disordered waveguide. In the diffuse regime, the short-range spatial structure of speckles is the same as for continuous wave (cw) illumination, whereas the long-range correlation between distant speckle spots grows linearly with time and can exceed its cw value. We discuss the physical origin of this phenomenon, compare our results to recent microwave experiments, and suggest that a similar linear growth with time should also be characteristic for other mesoscopic interference phenomena.

subject: Conservation Reserve Program

description: The Conservation Reserve Program (CRP) is a multi-year, multi-objective program of the 1985 Food Security Act scheduled to retire 40 million acres of highly erodible cropland by 1990. The Secretary of Agriculture has considerable discretion in implementing the program. This report analyzes the effects of various eligibility, pooling, and bid . selection criteria on the performance of the Conservation Reserve. The program can be implemented to favor erosion reduction, supply control, or budget reduction to varying degrees. Furthermore, the operation and performance of the CRP are closely linked with other conservation and commodity program provisions of the 1985 Food Security Act.
Prediction of MRI Hardware Failures based on Image Features using Ensemble Learning

description: In order to ensure trouble-free operation, prediction of hardware failures is essential. This applies especially to medical systems. Our goal is to determine hardware which needs to be exchanged before failing. In this work, we focus on predicting failures of 20-channel Head/Neck coils using image-related measurements. Thus, we aim to solve a classification problem with two classes, normal and broken coil. To solve this problem, we use data of two different levels. One level refers to one-dimensional features per individual coil channel on which we found a fully connected neural network to perform best. The other data level uses matrices which represent the overall coil condition and feeds a different neural network. We stack the predictions of those two networks and train a Random Forest classifier as the ensemble learner. Thus, combining insights of both trained models improves the prediction results and allows us to determine the coil's condition with an F-score of 94.14% and an accuracy of 99.09%.

description: UBC dining hall food waste decreased over the course of the first 2023W semester. This effect was driven by changes in dinner food waste. Additionally, introducing new menu items led to a brief, small uptick in food waste. We recommend creating waste reduction strategies that target dinner waste, such as reducing the serving size of new dinner menu items, as well as creating anti-waste messaging that is communicated to diners as early in the semester as possible.

Food Security and Poverty

description: The Conservation Reserve Program (CRP) of the 1985 Food Security Act is designed to retire "highly erodible" cropland from production. The CRP has multiple objectives, including reduced onsite and offsite environmental damages, supply control, and farm income maintenance. Another major conservation measure in the Act, the Highly Erodible Land Conservation (HEL) Subtitle, is designed to prevent farmers from receiving commodity program benefits if conservation plans are not implemented on their "highly erodible" lands. The definition(s) of "highly erodible" used for the CRP and HEL measures may be consistent with their objectives but inconsistent between measures. Or the definitions may be consistent between programs but inconsistent with program objectives. This paper presents an indepth discussion of using popular definitions of highly erodible and the impact on the consistency between programs and between programs and objectives.

description: This report contains papers presented at the December 1985 meeting of the International Agricultural Trade Research Consortium in Vancouver, British Columbia, Canada. The program theme of this meeting focused on the current practice and future research agenda of agricultural trade modeling. The report discusses and illustrates some major existing agricultural trade models by exercising them on a common set of scenarios. Comparison of the results from existing models can serve as a guide to the future improvement of trade models. The report also explores research issues that need to be addressed in future trade modeling work in the area of government policies and macro linkages to agricultural trade.

Singularity structure in Veneziano's model

Publisher: name: arXiv

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

description: We consider the structure of the cosmological singularity in Veneziano's inflationary model. The problem of choosing initial data in the model is shown to be unsolved -- the spacetime in the asymptotically flat limit can be filled with an arbitrary number of gravitational and scalar field quanta. As a result, the universe acquires a domain structure near the singularity, with an anisotropic expansion of its own being realized in each domain.

description: We investigate a Bose Einstein condensate held in a 1D optical lattice whose phase undergoes a fast oscillation using a statistical analysis. The averaged potential experienced by the atoms boils down to a periodic potential having the same spatial period but with a renormalized depth. However, the atomic dynamics also contains a \emph{micromotion} whose main features are revealed by a Kolmorogov-Smirnov analysis of the experimental momentum distributions. We furthermore discuss the impact of the micromotion on a quench process corresponding to a proper sudden change of the driving amplitude which reverses the curvature of the averaged potential.
