description: Mothers with insecure attachment styles may have increased difficulty establishing secure attachment with their infant and may experience emotion regulation difficulties in the postpartum period. This study aimed to examine the mediating effect of emotion dysregulation (ED) on the relationship between maternal insecure attachment style and self‐reported attachment to infant in women admitted to a mother‐baby unit. At admission, women completed self‐report questionnaires measuring attachment style, ED, postnatal attachment and postnatal depression (PND) symptoms. Descriptive statistics, correlations, and mediation analyses (PROCESS macro) were conducted. Insecure maternal attachment style was found to predict postnatal attachment through ED. When PND symptoms were accounted for, this model was no longer significant, and instead a serial mediation found that ED predicted PND, which was in turn associated with reduced postnatal attachment quality. This study provides preliminary support for continued research into maternal ED as a predictor of adverse maternal and infant outcomes postnatally. Individuals with attachment insecurity experiencing emotion regulation difficulties may be at an increased risk of developing PND and in turn experiencing adverse mother‐infant attachment outcomes. This has clinical implications for the screening, assessment and treatment of women experiencing mental health or attachment related concerns postnatally.

description: Tuberculosis (TB) remains a significant global health concern, necessitating accurate and timely diagnostic methods. This study aimed to conduct a systematic review and meta-analysis to assess the diagnostic accuracy of Truenat assays for both pulmonary TB (PTB) and extrapulmonary TB (EPTB). PubMed, Scopus, and Web of Science were systematically searched for studies comparing Truenat assays to Mycobacterium tuberculosis confirmation methods. Comparing Truenat MTB assay with the Lowenstein–Jensen (LJ) culture, the pooled sensitivity and specificity were 86% (95% CI: 79–91%) and 86% (95% CI: 82–90%), respectively. For Mycobacterial Growth Indicator Tube (MGIT) culture comparison, pooled sensitivity was 88% (95% CI: 82–92%) with a specificity of 79% (95% CI: 57–92%). Compared to smear microscopy, Truenat assays displayed pooled sensitivity and specificity of 92% (95% CI: 78–98%) and 86% (95% CI: 64–95%). In comparison to Xpert MTB/RIF, Truenat assays exhibited a pooled sensitivity of 92% (95% CI: 80–97%) and a pooled specificity of 92% (95% CI: 56–99%) for PTB detection, and a pooled sensitivity of 94% (95% CI: 81–98%) and a specificity of 77% (95% CI: 32–96%) for the diagnosis of EPTB. This study underscores the potential of Truenat assays as valuable tools for diagnosing both PTB and EPTB. CRD42024526686.

description: We develop a neutrino transfer code for core-collapse simulations, that directly solves the multidimensional Boltzmann equations in full general relativity. We employ the discrete ordinate method, which discretizes the six dimensional phase space. The code is an extension of our special relativistic code coupled to a Newtonian hydrodynamics code, which is currently employed for core-collapse supernova simulations. In order to demonstrate our code's capability to treat general relativistic effects, we conduct some tests: we first compute the free streaming of neutrinos in the Schwarzschild and Kerr spacetimes and compare the results with the geodesic curves; in the Schwarzschild case we deploy not only a 1-dimensional grid in space under spherical symmetry but also a 2-dimensional spatial mesh under axisymmetry in order to assess the capability of the code to compute the spatial advection of neutrinos; secondly, we calculate the neutrino transport in a fixed matter background, which is taken from a core-collapse supernova simulation with our general relativistic but spherically symmetric Boltzmann-hydrodynamics code, to obtain a steady neutrino distribution; the results are compared with those given by the latter code.

description: The paper deals with a particular type of a projective ring plane defined over the ring of double numbers over Galois fields, R\_{\otimes}(q) \equiv GF(q) \otimes GF(q) \cong GF(q)[x]/(x(x-1)). The plane is endowed with (q^2 + q + 1)^2 points/lines and there are (q + 1)^2 points/lines incident with any line/point. As R\_{\otimes}(q) features two maximal ideals, the neighbour relation is not an equivalence relation, i. e. the sets of neighbour points to two distant points overlap. Given a point of the plane, there are 2q(q+1) neighbour points to it. These form two disjoint, equally-populated families under the reduction modulo either of the ideals. The points of the first family merge with (the image of) the point in question, while the points of the other family go in a one-to-one fashion to the remaining q(q + 1) points of the associated ordinary (Galois) projective plane of order q. The families swap their roles when switching from one ideal to the other, which can be regarded as a remarkable, finite algebraic geometrical manifestation/representation of the principle of complementarity. Possible domains of application of this finding in (quantum) physics, physical chemistry and neurophysiology are briefly mentioned.

description: Quasicrystals exhibit exotic properties inherited from the self-similarity of their long-range ordered, yet aperiodic, structure. The recent realization of optical quasicrystal lattices paves the way to the study of correlated Bose fluids in such structures, but the regime of strong interactions remains largely unexplored, both theoretically and experimentally. Here, we determine the quantum phase diagram of two-dimensional correlated bosons in an eightfold quasicrystal potential. Using large-scale quantum Monte Carlo calculations, we demonstrate a superfluid-to-Bose glass transition and determine the critical line. Moreover, we show that strong interactions stabilize Mott insulator phases, some of which have spontaneously broken eightfold symmetry. Our results are directly relevant to current generation experiments and, in particular, drive prospects to the observation of the still elusive Bose glass phase in two dimensions and exotic Mott phases.

description: Very little is known about the effects on adult health of environmental conditions in developing countries. Most studies have focused on child health and few have included environmental factors. The shortcomings are associated with difficulties in measuring health status for adults and the limited availability of data on environmental conditions in developing countries. Schultz and Tansel conclude their study stating "the next step in this field of research is to distinguish what variations in public policies or natural variations in environmental conditions combine to explain existing variation in adult morbidity among wage earners." According to UNICEF, over half the population of Brazil live in an unsanitary environment. Worldwide, nearly three billion people do not have access to even a minimally sanitary toilet. This study assesses the effects of demographic factors and key environmental conditions on adult health in Brazil. The research focuses on morbidity among wage earners and the impact of specific environmental conditions. The analysis is based on a household model developed by Schultz and Tansel and treats work absence due to health problems as a measure of adult health status. The data used are from the 1989 Brazilian National Health and Nutrition Survey and 1989 National Basic Sanitation Condition Survey. The first is a household survey that measured individual health and nutrition. The second survey provides data on basic environmental and sanitary conditions at the municipality level.

description: We discuss shallow resonances in the nonrelativistic scattering of two particles using an effective field theory (EFT) that includes an auxiliary field with the quantum numbers of the resonance. We construct the manifestly renormalized scattering amplitude up to next-to-leading order in a systematic expansion. For a narrow resonance, the amplitude is perturbative except in the immediate vicinity of the resonance poles. It naturally has a zero in the low-energy region, analogous to the Ramsauer-Townsend effect. For a broad resonance, the leading-order amplitude is nonperturbative almost everywhere in the regime of validity of the EFT. We regain the results of an EFT without the auxiliary field, which is equivalent to the effective-range expansion with large scattering length and effective range. We also consider an additional fine tuning leading to a low-energy amplitude zero even for a broad resonance. We show that in all cases the requirement of renormalizability when the auxiliary field is not a ghost ensures the resonance poles are in the lower half of the complex momentum plane, as expected by other arguments. The systematic character of the EFT expansion is exemplified with a toy model serving as underlying theory.

description: Largely as a result of national surveys which have monitored the trends of individuals' well‐being from various perspectives, Australia is known to be a country in which people generally experience a high level of quality of life. Beyond the overall trends, this article aims to explore demographic, social, and psychological variables associated with Australians' life satisfaction, and identify important factors in each age and gender group. We analysed the data from the Gallup World Poll, which has collected nationally representative samples from Australia from 2005 to 2017. Overall, the data suggest that the relationship between age and life satisfaction is U‐curved. The gender gap remains consistent, favouring women across age groups. Although material quality of life is found to be the prime factor, the study also points to gender‐ and age‐specific factors that influence people's life satisfaction. The relative importance of city/area satisfaction to Australians' sense of well‐being is identified. Our comprehensive analysis implies that there is a need for better income support for people with very low incomes to improve their life satisfaction. Also, it would be of great benefit to Australia for the government and relevant policy makers to pay special attention to the improvement of healthcare services for the country's ageing population.

description: Helicobacter pylori causes stubborn infections and leads to a variety of stomach disorders, such as peptic ulcer, chronic atrophic gastritis, and gastric cancer. Although antibiotic-based approaches have been widely used against H. pylori, some challenges such as antibiotic resistance are increasing in severity. Therefore, simpler but more effective strategies are needed. In this review, basic information on functionalized and non-functionalized micro/nano biomaterials and routes of administration for H. pylori inhibition are provided in an easy-to-understand format. Afterward, in vitro and in vivo studies of some promising bio-platforms including metal-based biomaterials, biopolymers, small-molecule saccharides, and vaccines for H. pylori inhibition are discussed in a holistic manner. Functionalized or non-functionalized micro/nano biomaterials loaded with anti-H. pylori agents can show efficient bactericidal activity with no/slight negative influence on the host gastrointestinal microbiota. However, this claim needs to be substantiated with hard data such as assessment of the biopharmaceutical parameters of anti-H. pylori systems and the measurement of diversity/abundance of bacterial genera in the host gastric/gut microbiota before and after H. pylori eradication.

description: This paper addresses the growing concerns of local governments and residents about the high costs of urban spillover into adjoining rural areas. From a rural agricultural perspective we focus on the loss of productive agricultural land and open space. From a metropolitan core city perspective the focus shifts to the erosion of the city tax base and its fiscal capacity to pay for the associated high costs of neighborhood decline. From a personal and private perspective, however, urban growth creates new opportunities for residential and commercial development. Many sectors of the local economy share in these opportunities, including young families seeking their first single-family residence at a price they can afford. Given the multiplicity of concerns, the proposed solutions for managing urban metropolitan growth are many, but the outcomes are essentially the same: the converting of rural agricultural areas into suburban and open-country settlement continues unabated.

description: Temporal self‐appraisal theory proposes people perceive themselves as improving over time as a means of self‐enhancement. The current longitudinal study examined patterns of temporal self‐appraisal in individuals meeting criteria for a depressive and/or an anxiety disorder compared with healthy controls. Thirty‐four participants who met criteria for a depressive and/or anxiety disorder and 109 healthy controls were asked to appraise themselves as they currently were and how they expected to be in 4-weeks' time. Four weeks later, 20 participants who met criteria for a depressive and/or anxiety disorder and 62 healthy controls appraised themselves as they currently were and how they were 4-weeks ago (58 and 56% retention, respectively). Similar to healthy controls, participants with a depressive and/or anxiety disorder perceived the self on an upward trajectory over time. This occurred in the absence of actual improvement, reflecting self‐enhancing motives. Participants with a depressive and/or anxiety disorder had lower overall self‐appraisals. This highlights the need for therapy to target self‐appraisals in anxiety and depression. Patterns of temporal self‐appraisal may have a protective function in depression and anxiety that could be maximised in treatment.

description: Isotropization occurs on time scales much shorter than the thermal equilibration time. This is a crucial ingredient for the understanding of collision experiments of heavy nuclei or other nonequilibrium phenomena in complex many body systems. We discuss in detail the limitations of estimates based on standard ``linear'' or relaxation-time approximations, where isotropization and thermal equilibration rates agree. For a weak-coupling $ϕ^4$-model the relaxation-time approximation underestimates the thermal equilibration time by orders of magnitude, in contrast to the isotropization time. The characteristic nonequilibrium isotropization rate can be enhanced as compared to the close-to-equilibrium value. Our results are obtained from the two-particle irreducible effective action, which includes off-shell and memory effects and does not involve a gradient expansion. This allows us to determine the range of validity of a description to lowest-order in gradients, which is typically employed in kinetic equations.

Material examined
ESTONIA • 1 spec.; Vormsi Island, Hosholm shore; Adila Formation, Pirgu Regional Stage; GIT 878- 222.
Description
The specimen is a fragment of a complete body chamber and an additional 14 chambers of the phragmocone. The body chamber is ca 90° long with an unconstricted aperture with a wide U-shaped hyponomic sinus. The total fragment has a conch diameter of 113 mm, and the diameter of the preceding whorl is 83 mm. At its base, the width of the body chamber is 48 mm and the height 39 mm (CHI = 0.81), at the aperture it measures 60 mm in width and 45 mm in height (CHI = 0.75). The septal distance at the base of the body chamber is 6 mm at the venter. There is no sign of mature septal crowding. The sutures run straight and transverse over flanks and venter. At a position where the whorl height is 33 mm, the septal foramen of the siphuncle is ca 2.5 mm in diameter and is located ca 6 mm from the ventral conch margin (RSP = 0.20).
Remarks
The fragment does not permit species level determination because the more juvenile growth stages are not preserved. These are critical for species determination because many species of Charactoceras are differentiated by the extent of the annulation of the early growth stages. The WER of 1.85 of this specimen is lower than that of comparable growth stages of the type of C. estonicum (WER>3.5, compare Fig. 22A, D) and of other known species of Charactoceras. The species of Charactoceras with lowest known expansion rate is C. rotundum (WER: 1.9–2.4) from late Katian Strata of northern Greenland (Troedsson 1926). However, this latter species differs in having a siphuncle that is located more distantly from the ventral conch margin.

description: We address the ground-state properties of the long-standing and much-studied three-dimensional quantum spin liquid candidate, the $S=\frac 1 2$ pyrochlore Heisenberg antiferromagnet. By using $SU(2)$ density-matrix renormalization group (DMRG), we are able to access cluster sizes of up to 128 spins. Our most striking finding is a robust spontaneous inversion symmetry breaking, reflected in an energy density difference between the two sublattices of tetrahedra, familiar as a starting point of earlier perturbative treatments. We also determine the ground-state energy, $E_0/N_\text{sites} = -0.490(6) J$, by combining extrapolations of DMRG with those of a numerical linked cluster expansion. These findings suggest a scenario in which a finite-temperature spin liquid regime gives way to a symmetry-broken state at low temperatures.

description: As Noisy Intermediate-Scale Quantum (NISQ) devices grow in number of qubits, determining good or even adequate parameter configurations for a given application, or for device calibration, becomes a cumbersome task. An evolutionary algorithm is presented here which allows for the automatic tuning of the parameters of any arrangement of coupled qubits, to perform a given task with high fidelity. The algorithm's use is exemplified with the generation of schemes for the distribution of quantum states and the design of multi-qubit gates. The algorithm is demonstrated to converge very rapidly, yielding unforeseeable designs of quantum devices that perform their required tasks with excellent fidelities. Given these promising results, practical scalability and application versatility, the approach has the potential to become a powerful technique to aid the design and calibration of NISQ devices.

description: In the presence of a dilatonic coupling between an inflaton and a $U(1)$ gauge field, a persistent electric field (i.e., an anisotropic inflation) is obtained as a solution of the classical field equations. We introduce charged, massive, and conformally coupled fields into this model and study the pair production of charged particles. The semiclassical approach allows us to evaluate the induced current due to the pair production on the general dilatonic factor and electric field. Solving the field equations with the induced current, we find that the electric field shows a damped oscillation, whose amplitude decays to zero regardless of the values of the masses of charged fields. In other words, we derive a no-go theorem of anisotropic inflation by taking into account the Schwinger mechanism.

description: The dynamic characteristics of a tip oscillating in the nc-AFM mode in close vicinity to a Cu(100)-surface are investigated by means of phase variation experiments in the constant amplitude mode. The change of the quality factor upon approaching the surface deduced from both frequency shift and excitation versus phase curves yield to consistent values. The optimum phase is found to be independent of distance. The dependence of the quality factor on distance is related to 'true' damping, because artefacts related to phase misadjustment can be excluded. The experimental results, as well as on-resonance measurements at different bias voltages on an Al(111) surface, are compared to Joule dissipation and to a model of dissipation in which long-range forces lead to viscoelastic deformations.

description: We consider an occupancy scheme in which "balls" are identified with $n$ points sampled from the standard exponential distribution, while the role of "boxes" is played by the spacings induced by an independent random walk with positive and nonlattice steps. We discuss the asymptotic behavior of five quantities: the index $K_n^*$ of the last occupied box, the number $K_n$ of occupied boxes, the number $K_{n,0}$ of empty boxes whose index is at most $K_n^*$, the index $W_n$ of the first empty box and the number of balls $Z_n$ in the last occupied box. It is shown that the limiting distribution of properly scaled and centered $K_n^*$ coincides with that of the number of renewals not exceeding $\log n$. A similar result is shown for $K_n$ and $W_n$ under a side condition that prevents occurrence of very small boxes. The condition also ensures that $K_{n,0}$ converges in distribution. Limiting results for $Z_n$ are established under an assumption of regular variation.

description: Nel presente contributo si riportano i risultati di uno studio che coinvolge un gruppo di parlanti non nativi dell’italiano ai quali è stato chiesto di sperimentare alcune delle proposte didattiche presenti sul sito LIRA (Lingua/cultura Italiana in Rete per l’Apprendimento), creato per favorire lo sviluppo e il mantenimento di competenze pragmatico-culturali in italiano L2. I materiali di LIRA sono raggruppati in aree tematiche che coprono un’ampia gamma di argomenti legati agli usi pragmalinguistici e alle norme sociopragmatiche dell’italiano, e sono costruiti a partire dacampioni di parlato spontaneo o semi-spontaneo e da documenti scritti autentici.

Gli informanti sono stati invitati ad affrontare alcuni dei percorsi didattici di LIRA e la loro attività è stata monitorata per mezzo di protocolli di indagine introspettiva.I commenti mostrano come, nel complesso, tanto l’uso di input autentico quanto il ricorso a tipi di feedback che aprono al confronto invece di fornire un’unica soluzione corretta stimolino la riflessione e quindi contribuiscano allo sviluppo della consapevolezza sui fenomeni su cui si desidera attirare l’attenzione degli utenti. La scelta di fare affidamento esclusivamente su esempi autentici di uso della lingua consente inoltre di affrontare temi che vengono abitualmente trascurati nell’insegnamento dell’italiano a stranieri e che suscitano invece grande interesse e curiosità negli apprendenti.

Teaching italian pragmatics using LIRA: how do users react?

In this paper we report the results of a study involving a group of non-native speakers of Italian who were asked to do some of the educational proposals on the LIRA (Language / culture in Italian Network for Learning) site, created to encourage the development and maintenance of skills in pragmatic-cultural Italian L2. The LIRA materials are grouped into subject areas that cover a wide range of topics relating to Italian pragma-linguistic use and socio-pragmatic standards and are constructed from samples of spontaneous or semi-spontaneous speech and authentic written documents.
The informants were invited to try some of the educational LIRA activities and they were monitored through introspective survey protocols.  The comments show that, overall, the use of real input, as well as the use of feedback open to comparison,(rather than providing a single correct solution) stimulated reflection and thus contributed to the development of awareness of the phenomena meant to attract the users’ attention. The decision to rely solely on authentic language also made it possible to address issues that are usually neglected in teaching Italian to foreigners and created great interest and curiosity in the learners.

Arsenic and antimony biomethylation by Scopulariopsis brevicaulis
Creators: name: Andrewes, Paul
Publisher: name: University of British Columbia
Year: 2009

description: Many organisms have been isolated that transform inorganic arsenic compounds to organoarsenic species. In the case of antimony, simple alkylantimony species have been detected in the environment, but only a few organisms are known that produce these species. The fungus Scopulariopsis brevicaulis was selected as a model microorganism to study antimony biomethylation, because it is known for its ability to biomethylate the chemically similar element, arsenic. Cultures of S. brevicaulis were incubated with inorganic antimony compounds. Volatile antimony biomethylation products, in headspace gases, were determined by using gas chromatography inductively coupled plasma mass spectrometry, and nonvolatile species, in media samples, were determined by using hydride generation gas chromatography atomic absorption spectroscopy. Potassium antimony tartrate and antimony trioxide were biomethylated. The major biomethylation products (~95%) were nonvolatile dimethylantimony and trimethylantimony species, found in the medium. Volatile trimethylstibine (Me3Sb) was produced as a minor biomethylation product (~5%). The methyl source for antimony biomethylation was investigated, by incubating S. brevicaulis with potassium antimony tartrate and CD3-D-methionine, or 13CD3-L-methionine. There was significant, and comparable, incorporation of the methyl group from L-methionine into alkylantimony and alkylarsenic species. There was incorporation of the methyl group from D-methionine into alkylarsenic and alkylantimony species, but less than for L-methionine. These results suggest that antimony biomethylation proceeds via a mechanism very similar to that of arsenic biomethylation. Mixtures of antimony and arsenic compounds were incubated with S. brevicaulis and the biomethylation products determined. In these interaction studies, it was found that inorganic antimony(III) compounds inhibited arsenic biomethylation whereas inorganic arsenic(III) compounds enhanced antimony biomethylation. Microorganisms, resistant to the germicide, 10, 10'-oxybisphenoxarsine (OBPA), were isolated. The OBPA-resistant microorganisms, and S. brevicaulis, were incubated with OBPA for one month and the medium analyzed. There was no evidence, in the form of OBPA break-down products or intermediates on the pathway to trimethylarsine, to suggest that any of these microorganisms might produce volatile arsines from OBPA. Furthermore, when headspace gases from S. brevicaulis cultures, grown in medium containing OBPA, were analyzed, no significant amounts of trimethylarsine were detected.

description: This paper employed a variety of sources of data and a number of methods to describe rural lending markets. Over the sample period, 1992 through 1998, there was a pronounced trend towards affiliation of banks, both urban and rural, with holding companies, although over this period there was little change in the concentration of banking offices in rural areas. Using data from the 1993 National Survey of Small Business Finances, the study found some evidence that rural small businesses were less likely to apply for a loan than urban small firms although those rural firms that did apply were more likely to have their application accepted.

description: The stationary states of systems with many molecular motors are studied theoretically for uniaxial and centered (aster-like) arrangements of cytoskeletal filaments using Monte Carlo simulations and a two-state model. Mutual exclusion of motors from binding sites of the filaments is taken into account. For small overall motor concentration, the density profiles are exponential and algebraic in uniaxial and centered filament systems, respectively. For uniaxial systems, exclusion leads to the coexistence of regions of high and low densities of bound motors corresponding to motor traffic jams, which grow upon increasing the overall motor concentration. These jams are insensitive to the motor behavior at the end of the filament. In centered systems, traffic jams remain small and an increase in the motor concentration leads to a flattening of the profile, if the motors move inwards, and to the build-up of a concentration maximum in the center of the aster if motors move outwards. In addition to motors density patterns, we also determine the corresponding patterns of the motor current.

description: High dimensional integrals are abundant in many fields of research including quantum physics. The aim of this paper is to develop efficient recursive strategies to tackle a class of high dimensional integrals having a special product structure with low order couplings, motivated by models in lattice gauge theory from quantum field theory. A novel element of this work is the potential benefit in using lattice cubature rules. The group structure within lattice rules combined with the special structure in the physics integrands may allow efficient computations based on Fast Fourier Transforms. Applications to the quantum mechanical rotor and compact $U(1)$ lattice gauge theory in two and three dimensions are considered.
PRODUCTION PRACTICE ALTERNATIVES FOR INCOME AND SUITABLE FIELD DAY RISK MANAGEMENT

description: Production risk includes yield and days suitable for fieldwork variability. Both were modeled using biophysical simulation and a mean-variance, chance-constrained mathematical programming formulation representing a Kentucky corn, soybean, and wheat producer. While crop diversification, planting date, and maturity group can be used to reduce the types of risk considered, interaction between the two influences how production practices are used to manage risk. For the conditions studied, plant population alterations were less effective for risk reduction of either component. The study provides evidence of the importance of the consideration of both elements of production risk in whole farm planning.

description: This paper presents a short evaluation about the integration of information derived from wavelet non-linear-time-invariant (non-LTI) projection properties using Support Vector Machines (SVM). These properties may give additional information for a classifier trying to detect known patterns hidden by noise. In the experiments we present a simple electromagnetic pulsed signal recognition scheme, where some improvement is achieved with respect to previous work. SVMs are used as a tool for information integration, exploiting some unique properties not easily found in neural networks.

description: As part of its strategy to attract new businesses, in 1994 the State of Alabama won the Mercedes Benz bid to establish an automobile assembly plant in Vance, Tuscaloosa County, Alabama at the cost of $222 to $253 million worth of incentives. The study assessed the economic impact of the Mercedes Benz investment using IMPLAN. The IMPLAN industry code 49, industrial construction, and industry code 384, motor vehicle, were used to project the impact of the investment for the construction and production phases respectively. The results from four scenarios indicated that the investment would generate sizable direct and indirect employment, income, output, and tax revenue for the state economy. From the estimated revenue, the pay-out period for the cost of the incentive would be from four to seven years. The scenarios also indicated that the increase in the volume of locally purchased automobile parts will increase the multiplier effects for the state economy. Currently, the direct benefits from the suppliers accrue to other states with established suppliers networks. The finding also suggested a heavy concentration of the impact of Mercedes Benz plant in the north and northeast part of the state. These countries were also the beneficiaries of past agglomeration economics in terms of critical physical infrastructure and human resource development.

description: We explore a new paradigm to study dissipative dark matter models using gravitational-wave observations. We consider a dark atomic model which predicts the formation of binary black holes such as GW190425 while obeying constraints from large-scale structure, and improving on the missing satellite problem. Using LIGO and Virgo gravitational-wave data from 12th September 2015 to 1st October 2019, we show that interpreting GW190425 as a dark matter black-hole binary limits the Chandrasekhar mass for dark matter to be below 1.4 $M_\odot$ at $> 99.9\%$ confidence implying that the dark proton is heavier than 0.95 GeV, while also suggesting that the molecular energy-level spacing of dark molecules lies near $10^{-3}$ eV and constraining the cooling rate of dark matter at low temperatures.

description: The farm level economic implications of the political turmoil surrounding tobacco are examined. Tobacco ranks first in crop receipts in the Southeastern United States. Free market advocates typically want to eliminate the tobacco program because of its cartel-like nature. Health advocates want to maintain the program because it limits tobacco production. Cigarette manufacturers tolerate the program because of the political support they receive from program stakeholders. The effects of cigarette price increases with and without a program are examined. Whether or not the program is maintained in the face of declining tobacco demand has significant implications for Southern agriculture.

description: Using Polyakov's functional integral approach with the Liouville action functional defined in \cite{ZT2} and \cite{LTT}, we formulate quantum Liouville theory on a compact Riemann surface X of genus g > 1. For the partition function and for the correlation functions with the stress-energy tensor components $$, we describe Feynman rules in the background field formalism by expanding corresponding functional integrals around a classical solution - the hyperbolic metric on X. Extending analysis in \cite{LT1,LT2,LT-Varenna,LT3}, we define the regularization scheme for any choice of global coordinate on X, and for Schottky and quasi-Fuchsian global coordinates we rigorously prove that one- and two-point correlation functions satisfy conformal Ward identities in all orders of the perturbation theory. Obtained results are interpreted in terms of complex geometry of the projective line bundle $\cE_{c}=λ_{H}^{c/2}$ over the moduli space $\mathfrak{M}_{g}$, where c is the central charge and $λ_{H}$ is the Hodge line bundle, and provide Friedan-Shenker \cite{FS} complex geometry approach to CFT with the first non-trivial example besides rational models.
