description: We study the decay properties of Tonks-Girardeau gases escaping from a double-well potential. Initially, the gases are constrained between two infinite $δ$ barriers with an on-center $δ$-split potential. The strength of one of the obstacles is suddenly reduced, and the particles start to tunnel to the open space. Using the resonance expansion method, we derive the single-term approximate expression for the $N$-particle survival probability and demonstrate its effectiveness in both the exponential and nonexponential regimes. We also predict a parity effect and provide physical insights into its nature at different stages of the time evolution. We conclude that only the initial phase of the decay of the many-particle state may comply with an exponential law. The decay properties are dramatically affected by the presence of the split barrier. Our results reveal the overall decay mechanism of unstable Tonks-Girardeau gases from single and double quantum wells.

description: Observations at 1 au have confirmed that enhancements in measured energetic particle fluxes are statistically associated with "rough" magnetic fields, i.e., fields having atypically large spatial derivatives or increments, as measured by the Partial Variance of Increments (PVI) method. One way to interpret this observation is as an association of the energetic particles with trapping or channeling within magnetic flux tubes, possibly near their boundaries. However, it remains unclear whether this association is a transport or local effect; i.e., the particles might have been energized at a distant location, perhaps by shocks or reconnection, or they might experience local energization or re-acceleration. The Parker Solar Probe (PSP), even in its first two orbits, offers a unique opportunity to study this statistical correlation closer to the corona. As a first step, we analyze the separate correlation properties of the energetic particles measured by the \isois instruments during the first solar encounter. The distribution of time intervals between a specific type of event, i.e., the waiting time, can indicate the nature of the underlying process. We find that the \isois observations show a power-law distribution of waiting times, indicating a correlated (non-Poisson) distribution. Analysis of low-energy \isois data suggests that the results are consistent with the 1 au studies, although we find hints of some unexpected behavior. A more complete understanding of these statistical distributions will provide valuable insights into the origin and propagation of solar energetic particles, a picture that should become clear with future PSP orbits.

description: A diffusive Lotka-Volterra competition model is considered for the combined effect of spatial dispersal and spatial variations of resource on the population persistence and exclusion. First it is shown that in a two-species system in which the diffusion coefficients, resource functions and competition rates are all spatially heterogeneous, the positive equilibrium solution is globally asymptotically stable when it exists. Secondly the existence and global asymptotic stability of the positive and semi-trivial equilibrium solutions are obtained for the model with arbitrary number of species under the assumption of spatially heterogeneous resource distribution. A new Lyapunov functional method is developed to prove the global stability of a non-constant equilibrium solution in heterogeneous environment.

description: We present the optical identification of mid-IR and radio sources detected in the European Large Area ISO Survey (ELAIS) areas N1 and N2. Using the r' band optical data from the Wide Field Survey we apply a likelihood ratio method to search for the counterparts of the 1056 and 691 sources detected at 15 micron and 1.4 GHz respectively, down to flux limits of S_{15}=0.5 mJy and S_{1.4 GHz}=0.135 mJy. We find that ~92% of the 15 micron ELAIS sources have an optical counterpart down to the magnitude limit of the optical data, r'=24. All mid-IR sources with fluxes S_{15} >= 3 mJy have an optical counterpart. The magnitude distribution of the sources shows a well defined peak at relatively bright magnitudes r'~18. About 20% of the identified sources show a point-like morphology; its magnitude distribution has a peak at fainter magnitudes than those of galaxies. The mid-IR-to-optical and radio-to-optical flux diagrams are presented and discussed in terms of actual galaxy models. Objects with mid-IR-to-optical fluxes larger than 1000 are found that can only be explained as highly obscured star forming galaxies or AGNs. Blank fields being 8% of the 15 micron sample have even larger ratios suggesting that they may be associated with higher redshift and higher obscured objects.

description: A method for taking uncertainty into account when formulating aggregate agricultural policies is applied to the feed grain program. The impact of alternative feed grain programs on net farm income, Government payments, and feed grain production in the Southeastern Coastal Plains is shown. A model is developed to explain planted acreages of the major competing crops. The effects of alternative feed grain programs are evaluated using Mqnte Carlo simulation to account for random variation. Confidence intervals are placed on estimates of income and production resulting from selected feed grain programs.

description: Axion-like particles (ALPs) are light, neutral, pseudo-scalar bosons predicted by several extensions of the Standard Model of particle physics -- such as the String Theory -- and are supposed to interact primarily only with two photons. In the presence of an external magnetic field, photon-ALP oscillations occur and can produce sizable astrophysical effects in the very-high energy (VHE) band ($100 \, {\rm GeV} - 100 \, {\rm TeV}$). Photon-ALP oscillations increase the transparency of the Universe to VHE photons partially preventing the gamma-gamma absorption caused by the Extragalactic Background Light (EBL). Moreover, they have important implications for active galactic nuclei (AGN) by modifying their observed spectra both for flat spectrum radio quasars (FSRQs) and BL Lacs. Many attempts have been made in order to constrain the ALP parameter space by studying irregularities in spectra due to photon-ALP conversion in galaxy clusters and the consequences of ALP emission by stars. Upcoming new VHE photon detectors like CTA, HAWC, GAMMA-400, LHAASO, TAIGA-HiSCORE, HERD and ASTRI will settle the issue.

description: In 1969, formula feed manufacturers utilized 23.1 percent of all the feed grains and wheat fed to livestock. Estimates of aggregate demand by the mixed feed ind.:-stry for corn, oats, barley, grain sorghum, and wheat are presented. As expected, all of the feed grains have elastic demands. Grain sorghum has the highest direct price elasticity (-5.42), followed by corn (-4.81), oats (-3.82), and barley (-2.75). The direct price elasticity of wheat is elltimated to be -0.85. The location of feed manufacturers is found to play an important role in the demand for feed ingredients.

description: In heavy ion collisions, transverse momentum broadening quantifies the modification of a hard probe due to interactions with the quark-gluon plasma (QGP). We calculate momentum broadening in the Glasma, which is the highly non-isotropic precursor stage of the QGP right after the collision. We show that the Glasma leads to anisotropic momentum broadening: high energy partons accumulate more momentum along the beam axis than transverse to it. The physical origin of anisotropic broadening can be traced back to differences in the shapes of chromo-electric and chromo-magnetic flux tubes in the Glasma. We provide semi-analytic results for momentum broadening in the dilute Glasma and numerical results from real-time lattice simulations of the non-perturbative dense Glasma.

description: Layered structure of Bi-2212 high $T_c$ superconductor (HTSC), provides a unique opportunity to probe quasiparticle density of states inside a bulk single crystal by means of intrinsic (interlayer) tunneling spectroscopy. Here I present a systematic study of intrinsic tunneling characteristics of Bi-2212 as a function of doping, temperature, magnetic field and intercalation. An improved resolution made it possible to simultaneously trace the superconducting gap (SG) and the normal state pseudo-gap (PG) in a close vicinity of $T_c$ and to analyze closing of the PG at $T^*$. The obtained doping phase diagram exhibits a critical doping point for appearance of the PG and a characteristic crossing of the SG and the PG close to the optimal doping. All this points towards coexistence of two different and competing order parameters in Bi-2212.

description: Homeowners around the world elevate houses to manage flood risks. Deciding how high to elevate a house poses a nontrivial decision problem. The U.S. Federal Emergency Management Agency (FEMA) recommends elevating existing houses to the Base Flood Elevation (the elevation of the 100-yr flood) plus a freeboard. This recommendation neglects many uncertainties. Here we analyze a case-study of riverine flood risk management using a multi-objective robust decision-making framework in the face of deep uncertainties. While the quantitative results are location-specific, the approach and overall insights are generalizable. We find strong interactions between the economic, engineering, and Earth science uncertainties, illustrating the need for expanding on previous integrated analyses to further understand the nature and strength of these connections. Considering deep uncertainties surrounding flood hazards, the discount rate, the house lifetime, and the fragility can increase the economically optimal house elevation to values well above FEMA recommendation.

description: The success of any innovation in the field of education depends greatly upon its proper implementation by the practitioners. The implementation depends upon practitioners’ attitude towards Continuous and Comprehensive Evaluation as per CBSE scheme. Teachers should have sound attitude towards Continuous and Comprehensive Evaluation. It lays emphasis on thought process and de- emphasizes memorization. CCE uses a variety of ways to collect information about the learner’s learning and progress in different subjects and co-curricular activities. For studying the school teachers’ attitude towards CCE, the study has been conducted on 200 school teachers in all, equal number from each of the school (10 teachers from 10 Government and 10 Private schools) as well as subject wise (Hindi, English, Social Science, Mathematics and Science) 2 teachers from each school were selected. The sample of 200 school teachers has been selected through random sampling method. A self made attitude scale based on 5 point Likert’s scale for assessing the school teachers’ attitude towards CCE has been used by researcher. In Attitude scale, 40 items has been responded by 100 Government and 100 Private school teachers.

description: We construct 7-dimensional compact Einstein spaces with conical singularities that preserve 1/8 of the supersymmetries of M-theory. Mathematically they have weak G_2-holonomy. We show that for every non-compact G_2-holonomy manifold which is asymptotic to a cone on a 6-manifold Y, there is a corresponding weak G_2-manifold with two conical singularities which, close to the singularities, looks like a cone on Y. Our construction provides explicit metrics on these weak G_2-manifolds. We completely determine the cohomology of these manifolds in terms of the cohomology of Y.

Understanding Communal Clashes During Religious Processions
Creators: name: Centre for Development Policy and Practice
Publisher: name: Zenodo
Year: 2024

description: The pluralistic and secular characteristic of India has been facing its most intense challenge as of late—with communal forces attempting to create an environment where violence could erupt at any given time. The process of communalisation that has been taking place during the reign of the Bharatiya Janata Party (BJP) (“Religious Freedom Worsened,” 2022) has increased fear and insecurity among the minority communities. One of the tools being utilised to further worsen harmony and peace is the use of religious processions. Armed religious processions being carried out by militant Hindutva groups such as the Bajrang Dal and Vishwa Hindu Parishad (VHP) have become more and more frequent in the past few years, leaving behind a trail of violence and destruction.

One such procession which created quite a stir was the Brajmandal Jalabhishek Yatra that was carried out in Nuh, Haryana on July 31, 2023. As the procession was being carried out in Nuh, communal clashes broke out between the members of the procession and the Muslim residents of that area. The harrowing aspect of the communal clash was that the violence boiled over and made its way to Gurugram (Jain, 2023), a prosperous business hub, right next to India’s capital Delhi. All of this took place one month before India hosted the G20 summit in Delhi (Farooqui, 2023). Such is the sociopolitical climate of India and callous attitude of the administration, which enables such communal clashes to take place.

In 2024, it was announced that Brajmandal Jalabhishek Yatra would be organised again. However, the 2024 iteration of the religious procession went through Nuh peacefully and the procession concluded without a single incident of communal violence. This report, written by the Centre for Development Policy and Practice (CDPP), aims to inquire into why no violence took place when the same procession was organised in 2024. The report aims to answer questions such as, what were the differences in the attitudes and manner in which the administration and the police operated, what elements within the religious procession were present in 2023 and not in 2024, and what was the ground level context due to which communal tensions were high. The answers to these questions and other related questions will enable us to understand how a religious procession, a ritual act which is supposed to be spiritual in nature, instead becomes a preliminary act of instigation which leads to communal clashes.

description: We use 7 years of electron and positron Fermi-LAT data to search for a possible excess in the direction of the Sun in the energy range from 42 GeV to 2 TeV. In the absence of a positive signal we derive flux upper limits which we use to constrain two different dark matter (DM) models producing $e^+ e^-$ fluxes from the Sun. In the first case we consider DM model being captured by the Sun due to elastic scattering and annihilation into $e^+ e^-$ pairs via a long-lived light mediator that can escape the Sun. In the second case we consider instead a model where DM density is enhanced around the Sun through inelastic scattering and the DM annihilates directly into $e^+ e^-$ pairs. In both cases we perform an optimal analysis, searching specifically for the energy spectrum expected in each case, i.e., a box-like shaped and line-like shaped spectrum respectively. No significant signal is found and we can place limits on the spin-independent cross-section in the range from $10^{-46}~cm^2$ to $10^{-44}~cm^2$ and on the spin-dependent cross-section in the range from $10^{-43}~cm^2$ to $10^{-41}~cm^2$. In the case of inelastic scattering the limits on the cross-section are in the range from $10^{-43}~cm^2$ to $10^{-41}~cm^2$. The limits depend on the life time of the mediator (elastic case) and on the mass splitting value (inelastic case), as well as on the assumptions made for the size of the deflections of electrons and positrons in the interplanetary magnetic field.

description: This study compares the effectiveness of two crop insurance plans: an individual farm-yield measurement similar to the current Federal Crop Insurance Corporation multi-peril program and an area-yield measurement method. These methods are examined for reduction in yield and gross farm income variability, including deficiency payments, using farm-level wheat yield data from 100 southcentra1 Kansas farms. Although an individual farm-level measurement plan is complex and suffers from moral hazard and adverse selection problems, it provides more gross farm income risk reduction than an area plan.

description: We introduce a symmetrization technique that allows us to translate a problem of controlling the deviation of some functionals on a product space from their mean into a problem of controlling the deviation between two independent copies of the functional. As an application we give a new easy proof of Talagrand's concentration inequality for empirical processes, where besides symmetrization we use only Talagrand's concentration inequality on the discrete cube {-1,+1}^n. As another application of this technique we prove new Vapnik-Chervonenkis type inequalities. For example, for VC-classes of functions we prove a classical inequality of Vapnik and Chervonenkis only with normalization by the sum of variance and sample variance.

description: Let $(\mathcal{C},\mathbb{E},\mathfrak{s})$ be an extriangulated category with a proper class $ξ$ of $\mathbb{E}$-triangles. The authors introduced and studied $ξ$-$\mathcal{G}$projective and $ξ$-$\mathcal{G}$injective in \cite{HZZ}. In this paper, we discuss Gorenstein homological dimensions for extriangulated categories. More precisely, we first give some characterizations of $ξ$-$\mathcal{G}$projective dimension by using derived functors on $\mathcal{C}$. Second, let $\mathcal{P}(ξ)$ (resp. $\mathcal{I}(ξ)$) be a generating (resp. cogenerating) subcategory of $\mathcal{C}$. We show that the following equality holds under some assumptions: $$\sup\{ξ\textrm{-}\mathcal{G}{\rm pd}M \ | \ \textrm{for} \ \textrm{any} \ M\in{\mathcal{C}}\}=\sup\{ξ\textrm{-}\mathcal{G}{\rm id}M \ | \ \textrm{for} \ \textrm{any} \ M\in{\mathcal{C}}\},$$ where $ξ\textrm{-}\mathcal{G}{\rm pd}M$ (resp. $ξ\textrm{-}\mathcal{G}{\rm id}M$) denotes $ξ$-$\mathcal{G}$projective (resp. $ξ$-$\mathcal{G}$injective) dimension of $M$. As an application, our main results generalize their work by Bennis-Mahdou and Ren-Liu. Moreover, our proof is not far from the usual module or triangulated case.

description: The droughts of 1988 and 1989 were a challenge and an opportunity for agricultural economists. Ag economists have in the past and continue in the present to address the information needs of producers and public policy makers that arise during a drought. Considering the role of the Land Grant Universities and the unique history of our discipline, agricultural economists might be expected by their clientel to develop a variety of programs to address both the micro and macroeconomic consequences of the 1988 and 1989 droughts. This paper addresses three issues. First, it will review and evaluate the drought programs implemented by ag economists in 14 states. Second, it will describe the drought programs implemented by ag economists at Kansas State University (KSU). The paper will also will discuss how KSU's drought impact study helped shape the policy making environment. Finally, it will present ideas for designing future drought programs that will provide timely information to producers and policy makers.

description: We compute the evolution of different abundance ratios in the Milky Way (MW) for two different sets of stellar yields. In one of them stellar rotation is taken into account and we investigate its effects on the chemical evolution model predictions. Moreover, we show that some abundance ratios offer an important tool to investigate the halo-disk discontinuity. For the first time it is shown that the effect of a halt in the star formation between the halo/thick disk and thin disk phases, already suggested from studies based both on Fe/O vs. O/H and Fe/Mg vs. Mg/H, should also be seen in a C/O versus O/H plot if C is produced mainly by low- and intermediate-mass stars (LIMS). The idea that C originates mainly from LIMS is suggested by the flat behavior of the [C/Fe] ratio as a function of metallicity, from [Fe/H]=-2.2 to solar, and by the fact that very recent C/O measurements for stars in the MW halo and disk seem to show a discontinuity around log(O/H)+12=8.4. Finally, a more gentle increase of N abundance with metallicity (or time), relative to models adopting the yields of van den Hoek and Groenewegen (1997), is predicted by using the stellar yields of Meynet and Maeder (2002 - which include stellar rotation but not hot-bottom burning) for intermediate mass stars. This fact has some implications for the timescales of N enrichment and thus for the interpretation of the nature of Damped Lyman Alpha Systems.

description: The eutectic system Sr2RuO4-Ru is referred to as the 3-K phase of the spin-triplet supeconductor Sr2RuO4 because of its enhanced superconducting transition temperature Tc of ~3 K. We have investigated the field-temperature (H-T) phase diagram of the 3-K phase for fields parallel and perpendicular to the ab-plane of Sr2RuO4, using out-of-plane resistivity measurements. We have found an upturn curvature in the Hc2(T) curve for H // c, and a rather gradual temperature dependence of Hc2 close to Tc for both H // ab and H // c. We have also investigated the dependence of Hc2 on the angle between the field and the ab-plane at several temperatures. Fitting the Ginzburg-Landau effective-mass model apparently fails to reproduce the angle dependence, particularly near H // c and at low temperatures. We propose that all of these charecteric features can be explained, at least in a qualitative fashion, on the basis of a theory by Sigrist and Monien that assumes surface superconductivity with a two-component order parameter occurring at the interface between Sr2RuO4 and Ru inclusions. This provides evidence of the chiral state postulated for the 1.5-K phase by several experiments.

description: The physiological plasticity of five cyanobacteria microbial mats from an extreme high temperature intertidal environment (SW Iceland) was analysed both daily and seasonally. Daily cycles under in situ natural conditions were monitored from June to October using pulse-amplitude modulated (PAM) fluorometry and pigment composition in order to study the photosynthetic performance of these microbial mats in relation to environmental fluctuations linked to irradiance and temperature. In vitro temperature and salinity experiments of photosynthetic responses were also conducted. A total of 10 taxa were identified, the most abundant species being Cyanobacterium sp. and Geitlerinema sp. The microbial mats showed a remarkable photosynthetic adaptation to daily and seasonal changes in temperature and solar radiation. For all microbial mats, rETRmax values decreased from June to October, while Fv/Fm remained constant in terms of absolute values. Although high irradiances during June and July affected photosynthesis through photoinhibition, recovery was observed under high temperatures (between 40–50°C), which supports the hypothesis that temperature is a determining factor in the photosynthetic performance of these cyanobacterial mats. Our results showed a significant increase in the Chla-b and phycobiliproteins content from June to October, as well as a significant decrease in total carotenoids content.
Massive Spin-2 Field in De Sitter Space

description: In this paper we present a covariant quantization of the ``massive'' spin-2 field on de Sitter (dS) space. By ``massive'' we mean a field which carries a specific principal series representation of the dS group. The work is in the direct continuation of previous ones concerning the scalar, the spinor and the vector cases. The quantization procedure, independent of the choice of the coordinate system, is based on the Wightman-Garding axiomatic and on analyticity requirements for the two-point function in the complexified pseudo-Riemanian manifold. Such a construction is necessary in view of preparing and comparing with the dS conformal spin-2 massless case (dS linear quantum gravity) which will be considered in a forthcoming paper and for which specific quantization methods are needed.

description: The present study aims atrevealingthe degree of secondary school principals` commitment  in Ma'an Governorate to the quality standards of governance from their teachers` perspectives. Thesamplecontains (1317) teachers of both genders in the Directorates of Education of Ma'an Governorate. They were chosenbya cluster random method.To achieve the studypurposes; an evaluation tool has been developed which finally consists of (39) items.Its validity and stability have been verified.

The results of this study indicate that the estimates of the degree of secondary school principals` commitment  in Ma'an Governorate to the quality standards of governance from their teachers` perspectivesrangedwithin the moderate level. The standard of institutional integrity has ranked first, followed by the standard of management and leadership, then the standard of learning and teaching.Moreover, there aren’t any statistically significant differences (α ≥ 0.05) attributed to the years of experience variable in all domains. On the other hand,there are statistically significant differences (α ≥ 0.05) attributed to the qualification variable in the institutional integrity domain, in favor of the bachelor holders. In addition,there are statistically significant differences (α ≥ 0.05) attributed to the gender variable in the learning outcomes  domain, in favor of females. The study recommends the necessity of activating quality standards of governance in public schools by urging school principals to adhere to these standards.

description: Despite the improvements in perception accuracies brought about via deep learning, developing systems combining accurate visual perception with the ability to reason over the visual percepts remains extremely challenging. A particular application area of interest from an accessibility perspective is that of reasoning over statistical charts such as bar and pie charts. To this end, we formulate the problem of reasoning over statistical charts as a classification task using MAC-Networks to give answers from a predefined vocabulary of generic answers. Additionally, we enhance the capabilities of MAC-Networks to give chart-specific answers to open-ended questions by replacing the classification layer by a regression layer to localize the textual answers present over the images. We call our network ChartNet, and demonstrate its efficacy on predicting both in vocabulary and out of vocabulary answers. To test our methods, we generated our own dataset of statistical chart images and corresponding question answer pairs. Results show that ChartNet consistently outperform other state-of-the-art methods on reasoning over these questions and may be a viable candidate for applications containing images of statistical charts.

description: We present analysis of Chandra X-ray observations of seven quasars that were identified as candidate sub-parsec binary supermassive black hole (SMBH) systems in the Catalina Real-Time Transient Survey (CRTS) based on apparent periodicity in their optical light curves. Simulations predict close-separation accreting SMBH binaries will have different X-ray spectra than single accreting SMBHs, including harder or softer X-ray spectra, ripple-like profiles in the Fe K-$α$ line, and distinct peaks in the spectrum due to the separation of the accretion disk into a circumbinary disk and mini-disks around each SMBH. We obtained Chandra observations to test these models and assess whether these quasars could contain binary SMBHs. We instead find that the quasar spectra are all well fit by simple absorbed power law models, with the rest frame 2-10 keV photon indices, $Γ$, and the X-ray-to-optical power slopes, $α_{\rm OX}$, indistinguishable from the larger quasar population. This may indicate that these seven quasars are not truly sub-parsec binary SMBH systems, or it may simply reflect that our sample size was too small to robustly detect any differences. Alternatively, the X-ray spectral changes might only be evident at higher energies than probed by Chandra. Given the available models and current data, no firm conclusions are drawn. These observations will help motivate and direct further work on theoretical models of binary SMBH systems, such as modeling systems with thinner accretion disks and larger binary separations.
