description: Using data from the FOCUS experiment (FNAL-E831), we study the decay of $Λ^+_c$ baryons into final states containing a $Λ$ hyperon. The branching fractions of $Λ^+_c$ into $Λπ^+$, $Λπ^+ π^+ π^-$ and $Λ\bar{K} ^0 K^+$ relative to that into $pK^-π^+$ are measured to be $0.217 \pm 0.013 \pm 0.020$, $0.508 \pm 0.024 \pm 0.024$ and $0.142 \pm 0.018 \pm 0.022$, respectively. We also report new measurements of $\frac{Γ(Λ^+_c \to Σ^0 π^+)}{Γ(Λ^+_c \to Λπ^+)} = 1.09 \pm 0.11 \pm 0.19$, $\frac{Γ(Λ^+_c \to Σ^0 π^+π^+ π^-)}{Γ(Λ^+_c \to Λπ^+ π^+ π^-)} = 0.26 \pm 0.06 \pm 0.09$ and $\frac{Γ(Λ^+_c \to Ξ(1690)^0(Λ\bar{K} ^0) K^+)}{Γ(Λ^+_c \to Λ\bar{K} ^0 K^+)} = 0.33 \pm 0.10 \pm 0.04$. Further, an analysis of the subresonant structure for the $Λ^+_c \to Λπ^+π^+π^-$ decay mode is presented.

description: The impact of the QCD critical point on the propagation of nonlinear waves has been studied. The effects have been investigated within the scope of second-order causal dissipative hydrodynamics by incorporating the critical point into the equation of state, and the scaling behaviour of transport coefficients and of thermodynamic response functions. Near the critical point, the nonlinear waves are found to be significantly damped which may result in the disappearance of the Mach cone effects of the away side jet. Such damping may lead to enhancement in the fluctuations of elliptic and higher flow coefficients. Therefore, the disappearance of Mach cone effects and the enhancement of fluctuations in flow harmonics in the event-by-event analysis may be considered as signals of the critical endpoint.

description: The most efficient approach to laser interferometric force sensing to date uses monochromatic carrier light with its signal sideband spectrum in a squeezed vacuum state. Quantum decoherence, i.e. mixing with an ordinary vacuum state due to optical losses, is the main sensitivity limit. In this work, we present both theoretical and experimental evidence that quantum decoherence in high-precision laser interferometric force sensors enhanced with optical cavities and squeezed light injection can be mitigated by a quantum squeeze operation inside the sensor's cavity. Our experiment shows an enhanced measurement sensitivity that is independent of the optical readout loss in a wide range. Our results pave the way for quantum improvements in scenarios where high decoherence previously precluded the use of squeezed light. Our results hold significant potential for advancing the field of quantum sensors and enabling new experimental approaches in high-precision measurement technology.

description: When working with micro data one sometimes encounters situations involving qualitative choices in addition to the continuous choices that are the traditional focus of empirical analysis. One such situation arises when we study the increase in multiple job-holdings among farm operators in western economies. In these analyses we are both interested in the qualitative choice of entering the off-farm labour market and the continuous choice of determining labour supply in all occupations. This paper presents a unified framework for formulating such a discrete/continuous choices that include randomness within the decision-making process. We consider the joint labour decisions of operator and spouse through an agricultural household model that combines the agricultural production, consumption, and labour supply decisions in a single framework. We develop a probabilistic decision rule for participating in off farm work and derive the demand functions in farm production and labour supply functions in off-farm sector.

description: With the goal of attempting to observe a stochastic gravitational wave background (SGWB) with LISA, the spectral separability of the cosmological and astrophysical backgrounds is important to estimate. We attempt to determine the level with which a cosmological background can be observed given the predicted astrophysical background level. We predict detectable limits for the future LISA measurement of the SGWB. Adaptive Markov chain Monte-Carlo methods are used to produce estimates with the simulated data from the LISA Data challenge (LDC). We also calculate the Cramer-Rao lower bound on the variance of the SGWB parameter uncertainties based on the inverse Fisher Information using the Whittle Likelihood. The estimation of the parameters is done with the 3 LISA channels $A$, $E$, and $T$. We simultaneously estimate the noise using a LISA noise model. Assuming the expected astrophysical background, a cosmological background energy density of around $Ω_{GW,Cosmo} \approx 1 \times 10^{-12}$ to $1 \times 10^{-13}$ can be detected by LISA.

description: Digital image correlation (DIC) has become a valuable tool to monitor and evaluate mechanical experiments of cracked specimen, but the automatic detection of cracks is often difficult due to inherent noise and artefacts. Machine learning models have been extremely successful in detecting crack paths and crack tips using DIC-measured, interpolated full-field displacements as input to a convolution-based segmentation model. Still, big data is needed to train such models. However, scientific data is often scarce as experiments are expensive and time-consuming. In this work, we present a method to directly generate large amounts of artificial displacement data of cracked specimen resembling real interpolated DIC displacements. The approach is based on generative adversarial networks (GANs). During training, the discriminator receives physical domain knowledge in the form of the derived von Mises equivalent strain. We show that this physics-guided approach leads to improved results in terms of visual quality of samples, sliced Wasserstein distance, and geometry score when compared to a classical unguided GAN approach.

description: We complete the study of the Poisson-Sigma model over Poisson-Lie groups. Firstly, we solve the models with targets $G$ and $G^*$ (the dual group of the Poisson-Lie group $G$) corresponding to a triangular $r$-matrix and show that the model over $G^*$ is always equivalent to BF-theory. Then, given an arbitrary $r$-matrix, we address the problem of finding D-branes preserving the duality between the models. We identify a broad class of dual branes which are subgroups of $G$ and $G^*$, but not necessarily Poisson-Lie subgroups. In particular, they are not coisotropic submanifolds in the general case and what is more, we show that by means of duality transformations one can go from coisotropic to non-coisotropic branes. This fact makes clear that non-coisotropic branes are natural boundary conditions for the Poisson-Sigma model.

description: Dans cette etude, j'examine le role de la contamination dans Trou de memoire d'Hubert Aquin et A I'ami qui ne m 'apas same la vie d'Herve Guibert ainsi que les aspects postmodernes de ces deux romans. Le premier chapitre situe mon projet dans le courant postmoderne. J'y decris d'abord le rapport entre la modernite, le modernisme et le postmodernisme. Je trace ensuite les reflexions de Jean-Francois Lyotard sur la « condition postmoderne ». Enfin, j'introduis les effets de contamination qui se manifestent dans cette litterature. Le deuxieme chapitre porte sur Trou de memoire et souleve la question identitaire, ce qui entraine une discussion sur les notions d'hybridite et de metamorphose. J'examine les formes et les fonctions de l'interdiscursivite et de Pintertextualite. Dans le troisieme chapitre, j'explore le role de la contamination aux niveaux formel et thematique dans A Vami qui ne m'a pas sauve la vie. Je fais appel a Michel Foucault en considerant les rapports de force qui se developpent dans ce roman. Enfin, ayant complete cette exploration des deux romans par le biais du postmodernisme, je conclus que la contamination produit une ecriture de l'incertitude.

description: It is well known that for all 2-colorings of the edges of $K_6$ there is amonochromatic triangle. Less well known is that there are two monochromatic triangles. More generally, for all 2-colorings of the edges of $K_n$ there are roughly $\ge n^3/24$ monochromatic triangles. Another way to state this is that the density of monochromatic triangles is at least $1/4$. The Ramsey Multiplicity of $k$ is (asymptotically) the greatest $\alpha$ such that for every coloring of $K_n$ the density of monochromatic $K_k$'s is $\alpha$. This concept has been studied for many years. We survey the area and provide proofs that are more complete, more motivated, and using modern notation.

description: We investigate structural order in glassy water by performing classical molecular dynamics simulations using the extended simple point charge (SPC/E) model of water. We perform isochoric cooling simulations across the glass transition temperature at different cooling rates and densities. We quantify structural order by orientational and translational order metrics. Upon cooling the liquid into the glassy state, both the orientational order parameter $Q$ and translational order parameter $τ$ increase. At T=0 K, the glasses fall on a line in the $Q$-$τ$ plane or {\it order map}. The position of this line depends only on density and coincides with the location in the order map of the inherent structures (IS) sampled upon cooling. We evaluate the energy of the IS, $e_{IS}(T)$, and find that both order parameters for the IS are proportional to $e_{IS}$. We also study the structural order during the transformation of low-density amorphous ice (LDA) to high-density amorphous ice (HDA) upon isothermal compression and are able to identify distinct regions in the order map corresponding to these glasses. Comparison of the order parameters for LDA and HDA with those obtained upon isochoric cooling indicates major structural differences between glasses obtained by cooling and glasses obtained by compression. These structural differences are only weakly reflected in the pair correlation function. We also characterize the evolution of structural order upon isobaric annealing, leading at high pressure to very-high density amorphous ice (VHDA).

description: We employ the "complexity equals action" conjecture to investigate the action growth rate for the charged and neutral AdS black branes of a holographic toy model consisting of Einstein-Maxwell theory in $d + 1$-dimensional bulk spacetime with $d - 1$ massless scalar fields which is called Einstein-Maxwell-Axion (EMA) theory. From the holographic point of view, the scalar fields source a spatially dependent field theory with momentum relaxation on the boundary, which is dual to the homogeneous and isotropic black branes. We find that the growth rate of the holographic complexity within the Wheeler-DeWitt (WDW) patch saturates the corresponding Lloyd's bound at the late time limit. Especially for the neutral AdS black branes, it will be shown that the complexity growth rate at late time vanishes for a particular value of relaxation parameter $β_{max}$ where the temperature of the black hole is minimal. Then, we investigate the transport properties of the holographic dual theory in the minimum temperature. A non-linear contribution of the axion field kinetic term in the context of k-essence model in the four-dimensional spacetime is considered as well. We also study the time evolution of the holographic complexity for the dyonic AdS black branes in this model.

description: Biological condensates are assemblies of proteins and nucleic acids that form membraneless compartments in cells and play essential roles in cellular functions. In many cases they exhibit the physical properties of liquid droplets that coexist in a surrounding fluid. Recently, quantitative studies on the material properties of biological condensates have become available, revealing complex material properties. In vitro experiments have shown that protein condensates exhibit time dependent material properties, similar to aging in glasses. To understand this phenomenon from a theoretical perspective, we develop a rheological model based on the physical picture of protein diffusion and stochastic binding inside condensates. The complex nature of protein interactions is captured by a distribution of binding energies, incorporated in a trap model originally developed to study glass transitions. Our model can describe diffusion of constituent particles, as well as the material response to time-dependent forces, and it recapitulates the age dependent relaxation time of Maxwell glass observed experimentally both in active and passive rheology. We derive a generalized fluctuation-response relations of our model in which the relaxation function does not obey time translation invariance. Our study sheds light on the complex material properties of biological condensates and provides a theoretical framework for understanding their aging behavior.

Policy reform is likely to concentrate interest on the welfare of the agricultural household and the various sources of income that accrue to it. However, statistics that have the household-firm at their centre are poorly developed compared with those on agricultural activity. Reasons are explored and opportunities identified to correct this imbalance.

description: In non-relativistic quantum electrodynamics, an electromagnetic (EM) interaction between a photon and a molecular exciton can be expressed by a Ap term and A^2 term, where A and p are the operators of the vector potential of the EM field and the momentum of the exciton, respectively. We developed a method for investigating the contribution of the Ap and A^2 terms to EM enhancement, which occurs in coupled systems composed of a plasmon polariton and a molecular exciton. The spectral shapes of the Ap and A^2 terms terms, and the EM enhancement were experimentally obtained from absorption, Rayleigh scattering, and ultrafast surface enhanced fluorescence (ultrafast SEF) of the systems, respectively. The relationships between them reveal that the absorption spectra correctly reproduce EM enhancement, indicating that ultrafast SEF can be described as a two-step process using the Ap term. Furthermore, we demonstrate that the origin of spectral deviation between Rayleigh scattering and EM enhancement is subradiant plasmon resonance, which spectra are visualized in the absorption not in Rayleigh scattering, with numerical calculation based on electromagnetism.

description: We show that for positive integer values $l$ of the parameter in the conformal mechanics model the system possesses a hidden nonlinear superconformal symmetry, in which reflection plays a role of the grading operator. In addition to the even $so(1,2)\oplus u(1)$-generators, the superalgebra includes $2l+1$ odd integrals, which form the pair of spin-$(l+{1/2})$ representations of the bosonic subalgebra and anticommute for order $2l+1$ polynomials of the even generators. This hidden symmetry, however, is broken at the level of the states in such a way that the action of the odd generators violates the boundary condition at the origin. In the earlier observed double nonlinear superconformal symmetry, arising in the superconformal mechanics for certain values of the boson-fermion coupling constant, the higher order symmetry is of the same, broken nature.

description: Slow fluctuations of a qubit frequency are one of the major problems faced by quantum computers. To understand their origin it is necessary to go beyond the analysis of their spectra. We show that characteristic features of the fluctuations can be revealed using comparatively short sequences of periodically repeated Ramsey measurements, with the sequence duration smaller than needed for the noise to approach the ergodic limit. The outcomes distribution and its dependence on the sequence duration are sensitive to the nature of noise. The time needed for quantum measurements to display quasi-ergodic behavior can strongly depend on the measurement parameters.

description: Pre-trained models of source code have gained widespread popularity in many code intelligence tasks. Recently, with the scaling of the model and corpus size, large language models have shown the ability of in-context learning (ICL). ICL employs task instructions and a few examples as demonstrations, and then inputs the demonstrations to the language models for making predictions. This new learning paradigm is training-free and has shown impressive performance in various natural language processing and code intelligence tasks. However, the performance of ICL heavily relies on the quality of demonstrations, e.g., the selected examples. It is important to systematically investigate how to construct a good demonstration for code-related tasks. In this paper, we empirically explore the impact of three key factors on the performance of ICL in code intelligence tasks: the selection, order, and number of demonstration examples. We conduct extensive experiments on three code intelligence tasks including code summarization, bug fixing, and program synthesis. Our experimental results demonstrate that all the above three factors dramatically impact the performance of ICL in code intelligence tasks. Additionally, we summarize our findings and provide takeaway suggestions on how to construct effective demonstrations, taking into account these three perspectives. We also show that a carefully-designed demonstration based on our findings can lead to substantial improvements over widely-used demonstration construction methods, e.g., improving BLEU-4, EM, and EM by at least 9.90%, 175.96%, and 50.81% on code summarization, bug fixing, and program synthesis, respectively

description: In this paper we aim to push the analogy between thermodynamics and quantum resource theories one step further. Previous inspirations were based predominantly on thermodynamic considerations concerning scenarios with a single heat bath, neglecting an important part of thermodynamics that studies heat engines operating between two baths at different temperatures. Here, we investigate the performance of resource engines, which replace the access to two heat baths at different temperatures with two arbitrary constraints on state transformations. The idea is to imitate the action of a two--stroke heat engine, where the system is sent to two agents (Alice and Bob) in turns, and they can transform it using their constrained sets of free operations. We raise and address several questions, including whether or not a resource engine can generate a full set of quantum operations or all possible state transformations, and how many strokes are needed for that. We also explain how the resource engine picture provides a natural way to fuse two or more resource theories, and we discuss in detail the fusion of two resource theories of thermodynamics with two different temperatures, and two resource theories of coherence with respect to two different bases.

Magnon peak lineshape in the transverse dynamical structure factor of a magnetically polarized easy-axis $XXZ$ chain at low temperatures

description: The ferromagnetically polarized gapped XXZ spin chain is studied at low temperatures. Utilizing only the one- and two-magnon spectrums and focusing on the magnon-creation contribution to the transverse dynamical susceptibility, we represent the latter in the form of the Dyson equation. Then, following the well known correspondence between the imaginary part of magnetic susceptibility and dynamical structure factor, we get the low-temperature formula for the magnon-peak lineshape. The suggested approach is effective only if the processes related to magnon creations and to transitions from magnons to coupled magnon pairs are energetically separated. As it is shown in the paper, such separation is inherent in the easy-axis chains with rather strong anisotropy. We present several plots and discuss their lineshapes. As the supplemental result we obtain integral representations for the temperature-dependent magnon resonance shift and the parameter which is usually associated with the decay rate. The low-temperature behavior of the resonance shift is studied in details. All calculations are performed up to {\it controllable} error $o({\rm e}^{-βE_{gap}})$.

description: Предмет исследования взаимосвязь синдрома эмоционального выгорания с удовлетворенностью браком у мужчин и женщин. Предполагается, что чем выше удовлетворенность браком, тем ниже степень сформированности синдрома эмоционального выгорания. По результатам проведенного исследования взаимосвязи эмоционального выгорания и удовлетворенности браком у мужчин и женщин сделали вывод: 1. По методике В.В. Бойко доминирующими симптомами эмоционального выгорания у мужчин и женщин являются: «переживания психотравмирующих обстоятельств», «расширение сферы экономии эмоций», «редукции профессиональных обязанностей». 2. По методике В.В. Столина, Т.Л. Романовой, Г.П. Бутенко женщины чуть больше удовлетворены браком чем мужчины. 3. Анализ взаимосвязи удовлетворенности браком и фаз симптома эмоционального выгорания не дал значимых результатов на выборках. Однако, как было сказано ранее, когда мы, в общем, смотрим на состояние человека в профессии и в браке, то связь прослеживается. Из этого следует, что удовлетворенность в браке не является фактором, способным предотвратить или ускорить формирование какой-либо отдельной фазы, конкретного проявления, но при повышении степени удовлетворенности брачными отношениями общее состояние выгорания, как у мужчин, так и у женщин не так сильно выражено. Также после полученных результатов мы разработали рекомендации для сотрудников МБДОУ.

description: We investigate the properties of quantum annealing applied to the random field Ising model in one, two and three dimensions. The decay rate of the residual energy, defined as the energy excess from the ground state, is find to be $e_{res}\sim \log(N_{MC})^{-ζ}$ with $ζ$ in the range $2...6$, depending on the strength of the random field. Systems with ``large clusters'' are harder to optimize as measured by $ζ$. Our numerical results suggest that in the ordered phase $ζ=2$ whereas in the paramagnetic phase the annealing procedure can be tuned so that $ζ\to6$.

Farm Household Income Data in Canada: Approaches and Gaps

description: Canada, like other industrialized countries of the world, has seen its agriculture sector evolve dramatically over the past fifty years. Prior to the Second World War, Canadian society was largely composed of a large number of self- sufficient subsistence-level farming families, who for the most part, produced enough to feed themselves with occasionally, some surplus to trade with their neighbours, sell at community farmers' markets or provide to export markets. Farm households represented about one third of the Canadian population in 1941. Since the Second World War, however, dramatic improvements in technology in agriculture resulted in significant productivity gains. A smaller and smaller number of farm households operating increasingly larger, more specialized farms, with higher-than-average income, has been able to produce enough to feed Canadians and export to world markets. At the same time that the Canadian agriculture sector was being transformed, Canadian agriculture policy evolved. Early Canadian agriculture policy was concerned with finding immigrants to populate the vast empty Prairies and setting up experimental research farms across the country to develop and disseminate knowledge of new crops and production techniques adaptable to each individual region's climate (see Ndayisenga et al. (2002)). Subsequently Canadian agricultural policy evolved to ensure orderly marketing, price supports, production and yield insurance, farm income stabilization and support, and more recently, risk management. The objective of this paper is to describe the various sources of farm household income data in Canada and the gaps in data that have been identified over the past few years. The paper will begin with a description of the Canadian agriculture sector, including trends in farm household income. A discussion of the various sources of farm household data that are available in Canada will then be presented, including the approaches used. Finally, we will consider the data gaps that exist based on the experience of agricultural policy-makers and researchers while conducting policy development and analysis over the past few years.
