description: FeSeTe has recently emerged as a leading candidate material for the two-dimensional topological superconductivity (TSC). Two reasons for the excitement are the high $T_c$ of the system and the fact that the Majorana zero modes (MZMs) inside the vortex cores live on the exposed surface rather than at the interface of a heterostructure as in the proximitized topological insulators. However, the recent scanning tunneling spectroscopy data have shown that, contrary to the theoretical expectation, the MZM does not exist inside every vortex core. Hence there are ``full'' vortices with MZMs and ``empty'' vortices without MZMs. Moreover the fraction of ``empty'' vortices increase with an increase in the magnetic field. We propose the possibility of two distinct gapped states competing for the topological surface states in FeSeTe: the TSC and half quantum anomalous Hall (hQAH). The latter is promoted by magnetic field through the alignment of magnetic impurities such as Fe interstitials. When hQAH takes over the topological surface state, the surface will become transparent to scanning tunneling microscopy and the nature of the vortex in such region will appear identical to what is expected of the vortices in the bulk, i.e., empty. Unmistakable signature of the proposed mechanism for empty vortices will be the existance of chiral Majorana modes(CMM) at the domain wall between a hQAH region and a TSC region. Such CMM should be observable by observing local density of states along a line connecting an empty vortex to a nearby full vortex.

description: Aims. In this paper, we searched for multi-wavelength (X-ray, optical and radio) counterparts to the unassociated gamma-ray sources (UGS) of the Fermi 4FGL-DR4 catalog. The main goal is to identify new blazars and/or new active galactic nuclei (AGNs) emitting at GeV energies [like (Narrow Line) Seyfert-1 and radio galaxies]. Methods. We focus on sky regions observed by the Swift satellite that overlap with the reported positions of the UGSs. Since our primary interest lies in extra-galactic sources, we focus on UGSs located outside the Galactic plane (|b| > 10$^{\circ}$). Due to the large number of sources (about 1800 UGS), we developed a pipeline to automatise the search for counterparts and significantly reduce the computational time for the analysis. Our association process begins by identifying potential X-ray counterparts for each UGS; if one is found, we further look for corresponding radio and optical counterparts in the X-ray counterpart error box, thus minimizing ambiguities. Results. Out of the 1284 UGSs in the 4FGL-DR4 catalog, 714 were observed at least once by Swift/XRT. We detected, with a significance of $\geq$ 3$σ$, at least one X-ray source within the Fermi error box for 274 of these $γ$-ray emitters. Among these, 193 UGSs have a single potential X-ray counterpart (referred to as UGS1), while 81 have multiple potential X-ray counterparts within the Fermi error box (referred to as UGS2). Of the UGS2, 54 have two X-ray counterparts, 11 have three, and the remaining 16 have more than three. Each UGS1 has an optical counterpart, and 113 also could be associated to a radio counterpart. We performed a comparison of the possible counterpart properties with those of the $γ$-ray emitters identified by Fermi, with the aim to assess the goodness of our associations.

description: Let A = {rho_1,...,rho_n} be a given set of quantum states. We consider the problem of finding necessary and sufficient conditions on another set B = {sigma_1,...,sigma_n} that guarantee the existence of a physical transformation taking rho_i to sigma_i for all i. Uhlmann has given an elegant such condition when both sets comprise pure states. We give a simple proof of this condition and develop some consequences. Then we consider multi-probabilistic transformations between sets of pure states which leads to conditions for the problem of transformability between A and B when one set is pure and the other is arbitrary.

description: We present photometric and spectroscopic observations of SN 2013aa and SN 2017cbv, two nearly identical type Ia supernovae (SNe Ia) in the host galaxy NGC 5643. The optical photometry has been obtained using the same telescope and instruments used by the Carnegie Supernova Project. This eliminates most instrumental systematics and provides light curves in a stable and well-understood photometric system. Having the same host galaxy also eliminates systematics due to distance and peculiar velocity, providing an opportunity to directly test the relative precision of SNe Ia as standard candles. The two SNe have nearly identical decline rates, negligible reddening, and remarkably similar spectra and, at a distance of $\sim 20$ Mpc, are ideal as potential calibrators for the absolute distance using primary indicators such as Cepheid variables. We discuss to what extent these two SNe can be considered twins and compare them with other supernova "siblings" in the literature and their likely progenitor scenarios. Using 12 galaxies that hosted 2 or more SNe~Ia, we find that when using SNe~Ia, and after accounting for all sources of observational error, one gets consistency in distance to 3 percent.

description: Despite the strong resilience of the French food industry during the recent economic crisis, the bankruptcy rate for this sector has dramatically increased since 2010. This paper focuses on the economic and financial determinants of firm exit due to bankruptcy in the French food industry and compares them with those for other manufacturing industries. Based on a large sample of firm-level data for the period 2001–2012, we show that the bankruptcy risk pattern differs between food industry firms and other manufacturing firms. Firm productivity is an important determinant of a firm’s probability of going bankrupt; productivity begins deteriorating 3 years before a failure. Controlling for firm productivity, we also show that credit cost has a positive and significant impact on the probability of bankruptcy. However, we observe smaller effect of credit cost on firms’ bankruptcy risk. In contrast, productivity appears to have an important beneficial effect on bankruptcy risk reduction.

description: The use of knowledge graphs in recommender systems has become one of the common approaches to addressing data sparsity and cold start problems. Recent advances in large language models (LLMs) offer new possibilities for processing side and context information within knowledge graphs. However, consistent integration across various systems remains challenging due to the need for domain expert intervention and differences in system characteristics. To address these issues, we propose a consistent approach that extracts both general and specific topics from both side and context information using LLMs. First, general topics are iteratively extracted and updated from side information. Then, specific topics are extracted using context information. Finally, to address synonymous topics generated during the specific topic extraction process, a refining algorithm processes and resolves these issues effectively. This approach allows general topics to capture broad knowledge across diverse item characteristics, while specific topics emphasize detailed attributes, providing a more comprehensive understanding of the semantic features of items and the preferences of users. Experimental results demonstrate significant improvements in recommendation performance across diverse knowledge graphs.

Productivity Analysis

description: This paper aims to evaluate the direction, nature, and magnitude of spillovers between foreign-owned firms and French firms from firm-level panel data. We estimate production functions at the firm level using the recent structural techniques suggested in Ackerberg et al. (2006). From our results, three main conclusions can be drawn. First, spillovers are at work in all research-intensive sectors, although they have very weak effects in the less knowledge-based sectors. Second, foreign-owned firms belonging to high- and medium-technology manufacturing industries that are set up in France benefit from horizontal spillovers, suggesting a technology sourcing activity of foreign multinationals. Third, inward foreign investment increases the total factor productivity of French firms supplying inputs to multinationals (backward spillovers) only in high- and medium-technology manufacturing industries and after 4 years.

description: Sustainable food concerns have pushed public authorities to act by means of regulations, standards and other devices, and businesses to innovate in their products and production processes. We argue that the Porter hypothesis—which asserts that properly designed and implemented environmental regulation might be good for society as well as the targeted firms—might well be verified in this context. After reviewing and illustrating the working principles and main criticisms of this hypothesis, we provide a more in-depth discussion of nutritional issues. While the literature generally points to organizational imperfections and market failures to validate the Porter hypothesis, we submit and model another rationale for the agro-food industry, a rationale that is based on consumer behavior.

We investigate the feasibility of using this relation to extract the pion decay constant, by computing the zero-mode correlation functions on the lattice in the quenched approximation and comparing them with the corresponding expressions in quenched chiral perturbation theory.

description: We study the impact of public quality standards on industry structure in a context of international trade. We consider vertical differentiation in an international trade model based on monopolistic competition in which firms differ in terms of their productivity and must incur two fixed export costs when exporting to any given destination: a generic one (i.e., setting up a distribution system) and a destination-specific one to meet the quality standard prevailing in the importing country. Variable costs are also increasing in quality. The absolute mass of firms in any given country is decreasing in the domestic standard, but the relative mass (market share) of foreign firms is increasing in the domestic standard. Increasing public quality standards benefit highly productive foreign firms which gain from the quality-induced exit of less productive domestic and foreign firms. The increase in industry productivity following stricter public standards does not result from induced innovation as in the Porter hypothesis but from the exit of less productive firms.

description: The total deuterium abundance [D/H] in the universe is set by just two processes: the creation of deuterium in Big Bang Nucleosynthesis at an abundance of [D/H]$=2.58\pm0.13\times10^{-5}$, and its destruction within stellar interiors. Measurements of the total [D/H] abundance can potentially provide a probe of Galactic chemical evolution, however, most measurements of [D/H] are only sensitive to the gas-phase deuterium, and the amount of deuterium sequestered in carbonaceous dust grains is debated. With the launch of JWST, it is now possible to measure the gas-phase [D/H] at unprecedented sensitivity and distances through observation of mid-IR lines of H$_2$ and HD. We employ data from the JWST Observations of Young protoStars (JOYS) program to measure the gas-phase [D/H] abundance with a rotation diagram analysis towards 5 nearby low-mass and 5 distant high-mass protostellar outflows. The gas-phase [D/H] varies between low-mass sources by up to a factor of $\sim4$, despite these sources likely having formed in a region of the Galactic disk that would be expected to have nearly constant total [D/H]. Most measurements of gas-phase [D/H] from our work or previous studies produce [D/H] $\lesssim 1.0\times10^{-5}$, a factor of $2-4$ lower than found from local UV absorption lines and as expected from Galactic chemical evolution models. The variations in [D/H] between our low-mass sources and the low [D/H] with respect to Galactic chemical evolution models suggest that our observations are not sensitive to the total [D/H]. Significant depletion of deuterium onto carbonaceous dust grains is a possible explanation, and tentative evidence of enhanced [D/H] towards shock positions with higher gas-phase Fe abundance is seen in the HH 211 outflow. Deeper observations of HD and H$_2$ in shocked environments and modelling of dust-grain destruction are warranted to test for the effects of depletion.

description: Public and private expenditures for agricultural conservation in general and for soil erosion control in particular are developed from agency reports, other secondary materials, and farm-level interview surveys. The object was to provide baseline information for 1983 needed for an ERS benefit-cost study of erosion control. In 1983, the national cost of erosion control in the United States totaled about $1 billion. This was 43 percent of the $2.4 billion spent for all natural resource conservation efforts in agriculture. About 50 percent ($493 million) of the total costs of erosion control in 1983 was incurred by farm and ranch owners and operators, about 9 percent ($92 million) by State and local governments, and 42 percent ($423 million) by USDA agencies via congressional appropriations.

description: Counties that depend economically on farming and receive large amounts of Federal commodity payments will receive the greatest, most direct impact of farm policy adjustments. Yet, as their numbers declined, they became concentrated in a relatively small number of congressional districts in the Nation's midsection, limiting their political strength in Congress where farm policy is determined. More than 700 of the Nation's 2,443 rural counties depend on farming for at least 20 percent of their income and employment. This study, considering these as "farming-dependent" counties, identifies their geographic location and socioeconomic characteristics. About 200 of these 700 counties receive the highest per capita farm payments and are most dependent on farming.

description: In this paper we consider the Schrödinger operator in ${\mathbb R}^3$ with a long-range magnetic potential associated to a magnetic field supported inside a torus ${\mathbb{T}}$. Using the scheme of smooth perturbations we construct stationary modified wave operators and the corresponding scattering matrix $S(λ)$. We prove that the essential spectrum of $S(λ)$ is an interval of the unit circle depending only on the magnetic flux $ϕ$ across the section of $\mathbb{T}$. Additionally we show that, in contrast to the Aharonov-Bohm potential in ${\mathbb{R}}^2$, the total scattering cross-section is always finite. We also conjecture that the case treated here is a typical example in dimension 3.

description: Comparators have multifarious applications in various fields, especially used in analog to digital converters. Over the years, we have seen many different designs of single stage, dynamic latch type and double tail type comparators based on CMOS technology, and all of them had to make the tradeoff between power consumption and delay time. Meanwhile, to mitigate the short channel effects of conventional CMOS based design, FinFET has emerged as the most promising alternative by owning the tremendous gate control feature over the channel region. In this paper, we have analyzed the performance of some recent dynamic latch type comparators and proposed a new structure of dynamic latch comparator; moreover, 32nm FinFET technology has been considered as the common platform for all of the comparators circuit design. The proposed comparator has shown impressive performance in case of power consumption, time delay, power delay product and offset voltage while compared with the other recent comparators through simulations with LTspice.

description: FH Ser experienced a slow classical nova outburst in February 1970 that was the first one observed at UV, optical, and IR wavelengths. Its nova remnant is elliptical in shape, with multiple knots, and a peculiar ring-like filament along its minor axis. This work aims at unveiling its true 3D spatio-kinematical structure to investigate the effects of early shaping and to assess its mass and kinetic energy using VLT VIMOS integral field spectroscopic observations. The data cube has been analyzed using 3D visualisations that reveal different structural components. FH Ser consists of a tilted prolate ellisoidal shell, most prominent in H-alpha, and a ring-like structure, most prominent in [N II]. The ellipsoidal shell has equatorial and polar velocities of 505 and 630 km/s, respectively, with its major axis tilted by 52 deg with respect to the line of sight. The inclination angle of the symmetry axis of the ring is similar, i.e., it can be described as an equatorial belt of the main ellipsoidal shell. The ionized mass is 2.6E-4 solar mass, with a kinetic energy of 1.6E45 erg. The presence of two different structural components in FH Ser with similar orientation can be linked to a density enhancement along a plane, most likely the orbital plane at the time of the nova event. The acquisition of integral field spectroscopic observations of nova remnants is most required to disentangle different structural components and to assess their 3D physical structure.

description: Nonlinear interactions between phonon modes govern the behavior of vibrationally highly excited solids and molecules. Here, we demonstrate theoretically that optical cavities can be used to control the redistribution of energy from a highly excited coherent infrared-active phonon state into the other vibrational degrees of freedom of the system. The hybridization of the infrared-active phonon mode with the fundamental mode of the cavity induces a polaritonic splitting that we use to tune the nonlinear interactions with other vibrational modes in and out of resonance. We show that not only can the efficiency of the redistribution of energy be enhanced or decreased, but also the underlying scattering mechanisms may be changed. This work introduces the concept of cavity control to the field of nonlinear phononics, enabling nonequilibrium quantum optical engineering of new states of matter.

description: Additional file 1 : Supplementary Figure 1. The GFP1 Cas9 target sequence is shown (blue text) with the adjacent PAM site (red text). Three of the closest matches to this sequence in the yeast genome are shown below in the genes YLL012W, YJR102C and YOR131C. Mismatches to the canonical guide sequence are shown as lowercase black text. CATS was performed on GFP strains and non-GFP strains (BY4741) to determine whether these sequences would suffer mutations. After targeting, PCR was used to amplify the regions (shown as green bars) and these sequenced using Sanger sequencing. No mutations were identified. Supplementary Table 1. Plasmids used in this study. Table details the plasmids used in this study. pHT99 is a derivative of pWJ151 2[38] with the LEU2 marker replaced with NAT resistance gene. n/a indicates ‘not applicable’. Supplementary Table 2. Strains used in this study. Supplementary Table 3. Summary of tag-switching by plasmid transfer using the UDS. Growth on SC GAL 5-FOA G418 is indicted, which identifies strains that have genomic integration of the RFP-KAN template DNA. Cells were then checked with microscopy, N/A indicates that no colonies had formed. Supplementary Table 4. Counts of colonies formed from dissected spores on -HIS and G418 media. NUP170 and BIR1 tag switched strains fail to segregate the KAN (G418) marker correctly, whereas HTB2 and MPS1 tag switched strains show correct KAN (G418) segregation and linkage between the KAN (G418) and HIS marker genes. Supplementary Table 5. Phenotypes from dual targeting. Six colonies from each of three replicates that grew on YPD G418 HYG plates following targeting with a HYG cassette to replace CAN1 and an RFP-ADH1p-KAN cassette to replace GFP. Growth was tested on –ARG Canavanine to confirm the CAN1 gene has been disrupted then cells were checked for RFP signal with microscopy. HTB2-GFP (CAN1+) and the UDS (can1–100) were included on the –ARG Canavanine plates as controls.

description: Space-ground integrated network (SGIN) has been envisioned as a competitive solution for large scale and wide coverage of future wireless networks. By integrating both the non-terrestrial network (NTN) and the terrestrial network (TN), SGIN can provide high speed and omnipresent wireless network access for the users using the predefined licensed spectrums. Considering the scarcity of the spectrum resource and the low spectrum efficiency of the SGIN, we enable the NTN and TN to share the spectrum to improve overall system performance, i.e., weighted-sum area data rate (WS-ADR). However, mutual interference between NTN and TN is often inevitable and thus causes SGIN performance degradation. In this work, we consider a ground protection zone for the TN base stations, in which the NTN users are only allowed to use the NTN reserved spectrum to mitigate the NTN and TN mutual interference. We analytically derive the coverage probability and area data rate (ADR) of the typical users and study the performance under various protection zone sizes and spectrum allocation parameter settings. Simulation and numerical results demonstrate that the WS-ADR could be maximized by selecting the appropriate radius of protection zone and bandwidth allocation factor in the SGIN.
Charge-exchange-induced perturbations of ion and atom distribution functions in the heliospheric interface

description: Various hydrodynamic models of the heliospheric interface have been presented meanwhile, numerically simulating the interaction of the solar wind plasma bubble with the counterstreaming partially ionized interstellar medium. In these model approaches the resulting interface flows are found by the use of hydrodynamic simulation codes trying to consistently describe the dynamic and thermodynamic coupling of the different interacting fluids of protons, H-atoms and pick-up ions. Within such approaches, the fluids are generally expected to be correctly described by the three lowest velocity moments, i.e., by shifted Maxwellians. We shall show that in these approaches the charge-exchange-induced momentum coupling is treated in an unsatisfactory representation valid only at supersonic differential flow speeds. Though this flaw can be removed by an improved coupling term, we shall further demonstrate that the assumption of shifted Maxwellians in some regions of the interface is insufficiently well fulfilled both for H-atoms and protons. Using a Boltzmann-kinetic description of the proton- and H-atom- distribution functions coupled by charge exchange processes we emphasize the fact that non-negligible deviations from shifted Maxwellians are generated in the interface. This has to be taken into account when interpreting inner heliospheric measurements in terms of interstellar parameters.

description: Competitive, spatial price equilibrium models have been used extensively by international agricultural trade economists as research and policy analysis tools. These mathematical models of international trade are solved on large mainframe computers. It has become feasible to solve small spatial price equilibrium models with microcomputers. This report describes a microcomputer program designed to solve small, single commodity spatial equilibrium models. The program, GTP (Generalized Transportation Problem), was developed on an IBM PC-XT personal computer, but it should run on most microcomputers based on the 8086 and 8088 microprocessors.

description: This report compares rent-to-income ratios for metropolitan and nonmetropolitan rental households, controlling for income and other demographic characteristics. At the mean income level of approximately $12,000 for the sample, metro households pay approximately 4.5 percent more of their income on rent than do nonmetro renters of similar demographic characteristics. This differential falls to 3.3 percent after one adjusts for differences in urban/rural purchasing power, and it falls to 1.9 percent after one also controls for the quantity of housing consumed. This 1.9-percent rent-toincome differential results solely from differences in the price of housing in metro versus nonmetro areas.
TEACHERS' SELF-EFFICACY, PERCEIVED ADMINISTRATIVE SUPPORT AND POSITIVE ATTITUDE TOWARD STUDENTS: THEIR EFFECT ON COPING WITH JOB-RELATED STRESS

description: This study aimed at investigating the impact of teachers’ self-efficacy, perceptions of administrative support and positive attitude toward students on coping with job-related stress. A sample of 100 in-service primary and pre-primary state-school teachers fromthe urban region of Patras filled out four short measures on teachers’ self-efficacy, perceived administrative support, positive attitude toward students, and coping with job-related stress. Results indicated statistically significant correlations of teachers’ self-efficacy, perceived administrative support, and positive attitude toward students with coping with job-related stress. However, only teachers’ self-efficacy and positive attitude toward students predicted coping with job-related stress. The findings underscore the importance of the person as compared to institutional factors in the development of coping with job-related stress.

description: 4-ultilateral Tornqvist indices are computed with 1984-86 cost-of-production data for wheat from seven EC countries and the United States for cross-country comparisons. The major producers of wheat used almost equal quantities of goods and service inputs per unit of production. On the basis of a purchasing power standard, however, absolute costs of production in the United States are found to have been lower than in France and the United Kingdom. This study shows how costs of production can contribute to the understanding of international competitiveness.
PSYCHOMETRIC PROPERTIES OF THE BANGLA VERSION OF PSS-10: IS IT A SINGLE-FACTOR MEASURE OR NOT?

description: The Bangla version of the Perceived Stress Scale(PSS-B) is a popular and widely used measure in Bangladesh. Despite its popularity, it has never been validated among nonclinical samples in the country.The present study examined the psychometric properties of the PSS-B in a sample of 300 respondents. A two-factor structure was found in EFA performed on half of the sample (Sample 1, n = 150), explaining 53.41% of the total variance. The CFA performed on the second half of the sample (Sample 2, n = 150), showed that the two-factor model had acceptable fit. A one-factor and a bifactormodel were also tested. Good Cronbach’s alphas and significant test-retest reliability were observed in the scale. Concurrent validity of the scale was established through the correlation PSS-B with PSQ-B. Convergent and discriminant validities were established through inter-factor correlations as well as the scores of composite reliability, average variance extraction, average shared variance, and maximum shared variance. The results support the use of PSS-B with a two-factor structure as a reliable and valid measure to assess perceived stress of Bangladeshi people.

description: This study focuses on the flow of farm real estate debt by four types of farm lenders serving agriculture--commercial banks, the Farm Credit System, life insurance companies, and the Farmers Home Administration--instead of focusing on the more widely reported stock of farm real estate debt._JAnalysis of farm mortgage flow data from a variety of sources, including surveys and regulatory reports, indicates that recent agricultural mortgage origination volume has declined sharply from the peak of the late 1970's and early 1980's. Commercial banks, once a minor originator of agricultural mortgages, are now a major supplier. Both the Farm Credit System, once the dominant lender, and the Farmers Home Administration have experienced a sharply diminishing role in supplying agricultural mortgages in recent years.
