description: Numerical relativity (NR) simulations provide the most accurate binary black hole gravitational waveforms, but are prohibitively expensive for applications such as parameter estimation. Surrogate models of NR waveforms have been shown to be both fast and accurate. However, NR-based surrogate models are limited by the training waveforms' length, which is typically about 20 orbits before merger. We remedy this by hybridizing the NR waveforms using both post-Newtonian and effective one body waveforms for the early inspiral. We present NRHybSur3dq8, a surrogate model for hybridized nonprecessing numerical relativity waveforms, that is valid for the entire LIGO band (starting at $20~\text{Hz}$) for stellar mass binaries with total masses as low as $2.25\,M_{\odot}$. We include the $\ell \leq 4$ and $(5,5)$ spin-weighted spherical harmonic modes but not the $(4,1)$ or $(4,0)$ modes. This model has been trained against hybridized waveforms based on 104 NR waveforms with mass ratios $q\leq8$, and $|χ_{1z}|,|χ_{2z}| \leq 0.8$, where $χ_{1z}$ ($χ_{2z}$) is the spin of the heavier (lighter) BH in the direction of orbital angular momentum. The surrogate reproduces the hybrid waveforms accurately, with mismatches $\lesssim 3\times10^{-4}$ over the mass range $2.25M_{\odot} \leq M \leq 300 M_{\odot}$. At high masses ($M\gtrsim40M_{\odot}$), where the merger and ringdown are more prominent, we show roughly two orders of magnitude improvement over existing waveform models. We also show that the surrogate works well even when extrapolated outside its training parameter space range, including at spins as large as 0.998. Finally, we show that this model accurately reproduces the spheroidal-spherical mode mixing present in the NR ringdown signal.

description: We identify analytically a multiple-peak structure in the energy-density spectrum of induced gravitational waves (GWs) generated at second-order from a primordial scalar perturbations also with multiple($n$) peaks at small scales $k_{*i}$. The energy-density spectrum of induced GWs exhibits at most $C_{n+1}^2$ and at least $n$ peaks at wave-vectors $k_{ij}\equiv(k_{*i}+k_{*j})/\sqrt{3}$ due to resonant amplification, and, under the narrow-width approximation, it contains an universal factor that can be interpreted as a result of momentum conservation. We also extend these discussions to the case of non-Gaussian perturbations.

Glassy Vortex State in a Two-Dimensional Disordered XY-Model
Creators: name: Scheidl, Stefan
Publisher: name: arXiv
Year: 1996
Subjects: subject: Condensed Matter (cond-mat)
subject: FOS: Physical sciences

description: The two-dimensional XY-model with random phase-shifts on bonds is studied. The analysis is based on a renormalization group for the replicated system. The model is shown to have an ordered phase with quasi long-range order. This ordered phase consists of a glass-like region at lower temperatures and of a non-glassy region at higher temperatures. The transition from the disordered phase into the ordered phase is not reentrant and is of a new universality class at zero temperature. In contrast to previous approaches the disorder strength is found to be renormalized to larger values. Several correlation functions are calculated for the ordered phase. They allow to identify not only the transition into the glassy phase but also an additional crossover line, where the disconnected vortex correlation changes its behavior on large scales non-analytically. The renormalization group approach yields the glassy features without a breaking of replica symmetry.

description: Let $\mathcal{H}$ be a connected hereditary abelian category with tilting objects. It is proved that the cluster-tilting graph associated with $\mathcal{H}$ is always connected. As a consequence, we establish the connectedness of the tilting graph for the category $\operatorname{coh}\mathbb{X}$ of coherent sheaves over a weighted projective line $\mathbb{X}$ of wild type. The connectedness of tilting graphs for such categories was conjectured by Happel-Unger, which has immediately applications in cluster algebras. For instance, we deduce that there is a bijection between the set of indecomposable rigid objects of the cluster category $\mathcal{C}_{\mathbb{X}}$ of $\operatorname{coh}\mathbb{X}$ and the set of cluster variables of the cluster algebra $\mathcal{A}_{\mathbb{X}}$ associated with $\operatorname{coh}\mathbb{X}$.

description: Additional file 3. Time course of DNA glycosylase activity for the different hOGG1 variants. In each case, DNA substrate (20 nM) was incubated with hOGG1 (100 nM) for varying times prior to the reaction being quenched with sodium hydroxide. The double-stranded 20-mer DNA substrates contained a centrally located single 8oxoG base opposite cytosine. The products of the DNA glycosylase reaction were separated by denaturing polyacrylamide gel electrophoresis and the band intensities quantified. For each hOGG1 variant the glycosylase assay was replicated a minimum of three times. Error bars at the individual time points represent the standard deviation. The resulting data was averaged and fit to Eq. 1. The large variance in product formation for the R46Q hOGG1 variants was observed over numerous replicates of the glycosylase assay.

description: A dynamical model based on a continuous addition of colored shot noises is presented. The resulting process is colored and non-Gaussian. A general expression for the characteristic function of the process is obtained, which, after a scaling assumption, takes on a form that is the basis of the results derived in the rest of the paper. One of these is an expansion for the cumulants, which are all finite, subject to mild conditions on the functions defining the process. This is in contrast with the Levy distribution -which can be obtained from our model in certain limits- which has no finite moments. The evaluation of the power spectrum and the form of the probability density function in the tails of the distribution shows that the model exhibits a 1/f spectrum and long tails in a natural way. A careful analysis of the characteristic function shows that it may be separated into a part representing a Levy processes together with another part representing the deviation of our model from the Levy process. This allows our process to be viewed as a generalization of the Levy process which has finite moments.

description: We consider a 5-dimensional Chern-Simons gauge theory for the isometry group of Anti-de-Sitter spacetime, $\operatorname{AdS}_{4+1}\simeq\operatorname{SO}(4,2)$, and invoke different dimensional reduction schemes in order to relate it to 4-dimensional spin-2 theories. The AdS gauge algebra is isomorphic to a parametrized 4-dimensional conformal algebra, and the gauge fields corresponding to the generators of non-Abelian translations and special conformal transformations reduce to two vierbein fields in $D=4$. Besides these two vierbeine, our reduction schemes leave only the Lorentz spin connection as an additional dynamical field in the 4-dimensional theories. We identify the corresponding actions as particular generalizations of Einstein-Cartan theory, conformal gravity and ghost-free bimetric gravity in first-order form.

subject: Kosovo

description: The effects of support policies on technical efficiency are not clear and are very complex because the results may be either positive or negative. The effects can be positive if the money received will serve as an incentive to innovate or to switch to new technologies or can have a negative effect if the money received increase the income of the farms and as a result prefer to have more leisure time. Given the theoretical uncertainty of the impact of supporting policies on efficiency, productivity and added value, the aim of this paper is to address this issue empirically. This paper contributes to the literature for the case of Kosovo by fulfilling the following objectives (i) to measure technical efficiency of farms in Kosovo and (ii) to identify the effect of subsidies by employing a stochastic output distance function and an inefficiency effect model as the one proposed by Battese and Coelli (1995). Parametric stochastic frontier approach was employed to estimate technical efficiency and to determine the effect of exogenous variables on technical efficiency through one-step approach. The share of total subsidies to total output (%) was used as proxy for policy variable and a set of farm characteristics as exogenous variables. We used FADN of Kosovo data provided by MAFRED for 2014. The results suggest that on average a farm in Kosovo produced 15.7% of the maximum output, while the rest of the potential output was lost due to technical inefficiency. Subsidies had negative effect on technical efficiency, however insignificant.

description: We report new measurements of the drift velocity and longitudinal diffusion coefficients of electrons in pure xenon gas and in xenon-helium gas mixtures at 1-9 bar and electric field strengths of 50-300 V/cm. In pure xenon we find excellent agreement with world data at all $E/P$, for both drift velocity and diffusion coefficients. However, a larger value of the longitudinal diffusion coefficient than theoretical predictions is found at low $E/P$ in pure xenon, below the range of reduced fields usually probed by TPC experiments. A similar effect is observed in xenon-helium gas mixtures at somewhat larger $E/P$. Drift velocities in xenon-helium mixtures are found to be theoretically well predicted. Although longitudinal diffusion in xenon-helium mixtures is found to be larger than anticipated, extrapolation based on the measured longitudinal diffusion coefficients suggest that the use of helium additives to reduce transverse diffusion in xenon gas remains a promising prospect.

description: We present a twistor-like formula for the complete tree-level S matrix of 6D $(2,0)$ supergravity coupled to $21$ abelian tensor multiplets. This is the low-energy effective theory that corresponds to Type IIB superstring theory compactified on a $\mathrm{K}3$ surface. The formula is expressed as an integral over the moduli space of certain rational maps of the punctured Riemann sphere. By studying soft limits of the formula, we are able to explore the local moduli space of this theory, ${SO(5,21)\over SO(5)\times SO(21)}$. Finally, by dimensional reduction, we also obtain a new formula for the tree-level S matrix of 4D $\mathcal{N}=4$ Einstein-Maxwell theory.

description: In Ethiopia, sesame is mainly cultivated as a cash crop, important source of foreign exchange and income for many smallholders. Thus, improvement in production efficiency of sesame is crucial for Ethiopian economy and for smallholder farmer’s livelihood. Socioeconomic, demographic and institutional factors were collected from randomly selected 385 sample households using multi-stage sampling techniques and interviewed using semi-structured questionnaire. The Cobb-Douglas stochastic frontier production function result shows that all input variables except land was positive and significant effect on sesame production efficiency. Labour inputs have the highest elasticity, followed by sesame seed, pesticides/herbicides and fertilizer accordingly. The model result shows that across all mean technical, allocative, and economic efficiencies estimates are 72, 49 and 35 percent respectively, implies that a substantial level of inefficiency in sesame production. Improvement of production efficiency requires availability of enough labour particularly during harvesting because of its shattering problem. Therefore, the local and regional government needs to devise mechanisms for hired labour availability in the area. Moreover, the econometric model result indicates that sesame production efficiency was positively and significantly influenced by age, education level, livestock ownership, association membership, off/non-farm income, extension contact, credit access, mobile phone ownership and training participation. The key policy implication therefore is that promoting farmer’s cooperatives, address farmers in formal and informal education programs, enhancing farmer’s access to financial resources through providing easy and affordable credit services, strengthen the extension services in terms of promoting livestock and crop production improving technologies are crucial.

description: Varying weather conditions, including rainfall and snowfall, are generally regarded as a challenge for computer vision algorithms. One proposed solution to the challenges induced by rain and snowfall is to artificially remove the rain from images or video using rain removal algorithms. It is the promise of these algorithms that the rain-removed image frames will improve the performance of subsequent segmentation and tracking algorithms. However, rain removal algorithms are typically evaluated on their ability to remove synthetic rain on a small subset of images. Currently, their behavior is unknown on real-world videos when integrated with a typical computer vision pipeline. In this paper, we review the existing rain removal algorithms and propose a new dataset that consists of 22 traffic surveillance sequences under a broad variety of weather conditions that all include either rain or snowfall. We propose a new evaluation protocol that evaluates the rain removal algorithms on their ability to improve the performance of subsequent segmentation, instance segmentation, and feature tracking algorithms under rain and snow. If successful, the de-rained frames of a rain removal algorithm should improve segmentation performance and increase the number of accurately tracked features. The results show that a recent single-frame-based rain removal algorithm increases the segmentation performance by 19.7% on our proposed dataset, but it eventually decreases the feature tracking performance and showed mixed results with recent instance segmentation methods. However, the best video-based rain removal algorithm improves the feature tracking accuracy by 7.72%.

The effect of the unscreened magnetic modes of gluons on the value of the color condensate is studied. In particular, it is shown that, at sufficiently large values of the chemical potential, these modes lead to the enhancement of the superconducting order parameter. The interplay between the instanton induced interaction and the one-gluon induced one in color superconductivity is discussed.

description: Motivated by recent experiments, in which the Kondo effect has been observed for the first time in a double quantum-dot structure, we study electron transport through a system consisting of two ultrasmall, capacitively-coupled dots with large level spacing and charging energy. Due to strong interdot Coulomb correlations, the Kondo effect has two possible sources, the spin and orbital degeneracies, and it is maximized when both occur simultaneously. The large number of tunable parameters allows a range of manipulations of the Kondo physics -- in particular, the Kondo effect in each dot is sensitive to changes in the state of the other dot. For a thorough account of the system dynamics, the linear and nonlinear conductance is calculated in perturbative and non-perturbative approaches. In addition, the temperature dependence of the resonant peak heights is evaluated in the framework of a renormalization group analysis.

description: This paper attempted the nexus of food production and consumption, and determinants of food consumption in Gudo Beret watershed, central highlands of Ethiopia. The study used cross-sectional data collected from 211 randomly selected households through interview. Descriptive statistics and linear regression were the key analytical techniques. Results revealed that households produced a gross yield of 1.5 ton and a net food supply of 1.1 ton per household which was equivalent to 274 kg of grain per adult per annum. The average food demand per capita was 323.8 kg per adult. It implies food production was inadequate for food consumption. Sex of household head being male, livestock holding, inorganic fertilizer, total land size, and market distance affected household food consumption positively whereas household size had negative impacts on household food energy. One of the current themes of the food systems is balancing food production and consumption. The government of Ethiopia should deliberate population policy with the intention that the rising population need to have adequate subsistence. In addition, women empowerment can enable them access to and control over food resources.

description: Degenerate Hubbard models are studied using the Generalized-Gutzwiller-Approximation. It is found that the metal-insulator transition occurs at a finite correlation $U_c$ when the average number of electrons per lattice site is an integer. The critical $U_c$ depends sensitively on both the band degeneracy $N$ and the filling $x$. A derivation is presented for the general expression of $U_c(x,N)$ which reproduces all previously known Gutzwiller solutions, including that of the Boson Hubbard model. Effects of the lattice structure on the metal-insulator transition and the effective mass are discussed.

description: We study the vacuum structure of N_f flavour two-dimensional QED with an arbitrary integer charge k. We find that the axial symmetry is spontaneously broken from Z_(kN_f) to Z_(N_f) due to the non-vanishing condensate of a flavour singlet operator, resulting in k degenerate vacua. An explicit construction of the k vacua is given by using a non-commutative algebra obtained as a central extension of the Z_(kN_f) discrete axial symmetry and Z_k 1-form (center) symmetry, which represents the mixed 't Hooft anomaly between them. We then give a string theory realization of such a system with k=2 and N_f=8 by putting an anti D-string in the vicinity of an orientifold O1- plane and study its dynamics using the two-dimensional gauge theory realized on it. We calculate the potential between the anti D-string and the O1- plane and find repulsion in both weak and strong coupling regimes of the two dimensional gauge theory, corresponding to long and short distances, respectively. We also calculate the potential for the (Q,-1) string (the bound state of an anti D-string and Q fundamental strings) located close to the O1- plane. The result is non-perturbative in the string coupling.

description: Abstract
Water hyacinth (Eichhornia crassipes) occurs almost throughout wetlands of Africa and poses serious socioeconomic and environmental problems of people in riparian communities, which added constraints on the sluggish development process. This review aims to show the spatial distribution, characteristic and impacts of water hyacinth to initiate urgent policy attention and amelioration mechanisms in Rift Valley Lakes Basin (RVLB). This invasive weed has spread quickly from Amazon to many tropical and sub-tropical countries and known to cause major ecological, environmental, and socioeconomic challenges.

description: Στην παρούσα διπλωματική εργασία μελετήθηκε η χρηματοοικονομική ανάλυση πέντε εταιριών τροφίμων μέσω της χρήσης του εργαλείου των αριθμοδεικτών για τη χρονική περίοδο 2017-2021, έτσι ώστε με αυτό τον τρόπο να καταστεί εφικτή η εξέταση του τρόπου με τον οποίο επίδρασε η πανδημία του COVID 19 τον κλάδο αυτό.
Πιο συγκεκριμένα, από τα όσα αναλύθηκαν στην παρούσα εργασία κατέστη σαφές, ότι ο κλάδος των τροφίμων επηρεάστηκε σημαντικά από την πανδημία, καθώς όλοι οι αριθμοδείκτες δραστηριότητας και αποδοτικότητας των εταιριών εμφάνισαν σημαντική χειροτέρευση το 2020, ενώ ειδικά στο πεδίο της αποδοτικότητας σχεδόν όλες οι εξεταζόμενες εταιρίες του κλάδου εμφάνιζαν ζημιές μετά φόρων.
Αντίθετα, βελτίωση εμφάνισε ο κλάδος τροφίμων αλλά και η πλειονότητα των εξεταζόμενων εταιριών στο πεδίο της ρευστότητας εν μέσω της πανδημίας, ενώ σε ότι αφορά την κεφαλαιακή διάρθρωση όλες οι εξεταζόμενες εταιρίες βασίζουν τη δραστηριοποίηση τους στα δανειακά κεφάλαια και όχι στα ίδια κεφάλαια, γεγονός το οποίο έχει σαν συνέπεια να βρίσκονται οι εταιρίες αυτές εκτεθειμένες στον πιστωτικό κίνδυνο.
Τέλος, όσον αφορά την εταιρία που βρίσκεται στη πλέον δυσμενή θέση, αυτή είναι η ΣΑΒΟΪΔΑΚΗΣ ΑΕ, η οποία εμφανίζει συνολικά σε όλα τα έτη που μελετήθηκαν ζημιές μετά φόρων αντί για κέρδη, ενώ με εξαίρεση το 2020 εμφανίζει συνεχώς αρνητικά ίδια κεφάλαια την περίοδο 2017-2021. Η εξέλιξη αυτή καθιστά ζωτικής σημασίας την ανάγκη λήψης μέτρων από την πλευρά της εταιρίας, έτσι ώστε να μην απειληθεί περαιτέρω η βιωσιμότητα και φερεγγυότητα της εταιρίας.

description: In this thesis, the financial analysis of five food companies was studied through the financial ratios tool for the period 2017-2021, so that it became possible to examine how the pandemic of COVID 19 affected the sector.
More specifically, from what was analyzed in this paper, it became clear that the food sector was significantly affected by the pandemic, as all the activity and efficiency indicators of the companies showed a significant deterioration in 2020, while especially in the field of efficiency, most of the examined companies of the sector were showing losses after taxes.
On the contrary, the food sector and the majority of the examined companies showed an improvement in the field of liquidity in the midst of the pandemic, while with regard to the capital structure, all the examined companies base their activity on loan capital and not on equity, a fact which has the consequence that these companies are exposed to credit risk.
Finally, as regards the company that is in the most unfavorable position, this is SAVOIDAKIS SA, which shows losses after taxes instead of profits throughout the period under review, while with the exception of year 2020 it continuously shows negative equity in the period 2017-2021. This development makes the need to take measures on the part of the company vital, so as not to further threaten the viability and solvency of the company.

description: We extend the study of the two-dimensional euclidean $ϕ^4$ theory initiated in ref. [1] to the $\mathbb Z_2$ broken phase. In particular, we compute in perturbation theory up to N$^4$LO in the quartic coupling the vacuum energy, the vacuum expectation value of $ϕ$ and the mass gap of the theory. We determine the large order behavior of the perturbative series by finding the leading order finite action complex instanton configuration in the $\mathbb Z_2$ broken phase. Using an appropriate conformal mapping, we then Borel resum the perturbative series. Interestingly enough, the truncated perturbative series for the vacuum energy and the vacuum expectation value of the field is reliable up to the critical coupling where a second order phase transition occurs, and breaks down around the transition for the mass gap. We compute the vacuum energy using also an alternative perturbative series, dubbed exact perturbation theory, that allows us to effectively reach N$^8$LO in the quartic coupling. In this way we can access the strong coupling region of the $\mathbb Z_2$ broken phase and test Chang duality by comparing the vacuum energies computed in three different descriptions of the same physical system. This result can also be considered as a confirmation of the Borel summability of the theory. Our results are in very good agreement (and with comparable or better precision) with those obtained by Hamiltonian truncation methods. We also discuss some subtleties related to the physical interpretation of the mass gap and provide evidence that the kink mass can be obtained by analytic continuation from the unbroken to the broken phase.

description: The upsurge of land deals in Northern Ghana is a concern to many stakeholders. In order to reduce the effects of land deals on livelihoods, farmers resort to adopting semi-intensive, intensive or low intensive farming systems. Using a multinomial logit model, this study assessed how land deals influence the decision of a farm household to choose any of the farming regimes. Factors that influence farmers’ decision to choose intensive as against semi-intensive methods of farming are farm size, awareness of land grabbing, intension of cultivating part of grabbed land, number of adults, household expenditure, location, remittances and land grabbed investment type. On the other hand, households’ engagement in low intensive as compared to semi-intensive methods of farming are influenced by age, fallowing period, education, remittances, and household expenditure. Land deals must be accompanied by efforts to diversify livelihoods of smallholder farmers away from land-based systems. This would require skills training for rural peasant farmers to enable them take up emerging livelihood opportunities. In order to safeguard the interests and livelihood of rural peasants, agricultural investment programmes must make community-investor partnership a key condition for gaining access to government and donor incentives.

description: We investigated the Integer Quantum Hall Effect (IQHE) using an inductive method. The following conclusions can be derived from our study: (i) when the Fermi energy is located between Landau levels the only extended states at the Fermi energy are located at the physical edges of the sample. (ii) the extended states located at the bulk of the sample below the Fermi energy are capable of carrying a substantial amount of Hall current, but cannot screen an external electrostatic potential.

description: Commercial opportunity for indigenous Aloe Vera products appear to be increasing as there is a sustained demand from international as well as African market with high participation of women. However, its income impact on the livelihood of household is not yet addressed. Therefore, this study evaluated the income impact of pastoralist women participation in Aloe Vera soap production in Yabello district, Borana zone of Oromia, Ethiopia. Both primary and secondary data were collected from 200 sample households using semi-structured questionnaire. To analyse the data both descriptive and inferential statistics and Propensity Score Matching model were applied. The Propensity Score Matching was applied the required matching processes, covariate balancing and sensitivity analysis tests. The result shows that participation of women in Aloe Vera soap production has insignificant result with impact on household income. However, the propensity score matching also indicates average treatment effect on treated income is 45.693 Birr. Result of sensitivity analysis further shows that the estimated effects are insensitive to unobserved selection bias within gamma level used. Thus, Aloe Vera soap production should be encouraged for the pastoralist social wellbeing.

description: We consider an extension of the standard electroweak theory with gauge group $SU(2)_L \times SU(2)_R \times U(1)_{\tilde{Y}}$, where the gauge bosons of the extra $SU(2)_R$ factor do not couple to ordinary fermions. We show that precision electroweak data and flavour physics provide quite stringent indirect constraints on its parameter space, but still allow for relatively light non-standard gauge and Higgs bosons. We then consider the model phenomenology at high-energy colliders, and observe that in the gauge boson sector present bounds and possible future signals are dominated by $Z'$ production. In summary, indirect constraints on the charged gauge boson sector are so tight that observable new effects must be connected either with the neutral gauge boson sector or with the extended Higgs sector of the model.

description: Excerpts: Good extension teaching requires the judicious use of charts. Since economic facts often can be shown best through the use of charts, we have collected and are sending you herewith the important charts used in presenting the 1935 Farm Family Living Outlook Report. Charts 1 to 4, furnished by the Bureau of Agricultural Economics, give facts as to farm income, prices farmers receive, prices farmers pay, and price changes for food, clothing, operating expenses, building materials, furniture and furnishings, and all commodities used for family maintenance. Charts 5 to 7 show distribution of the average value of farm family living. Basic material upon which the charts are developed follows each chart. States that have household-account records doubtless will wish to substitute their own figures wherever possible. Charts 8 to 12 deal with the farm family food supply, including the usual versus the desirable distribution of food groups at different money-value levels, and the money value of the food supply required for a farm family while a son and a daughter are being retired to the age of self-support, together with explanatory material.
