description: We consider the most general effective action for the four-form fluxes in the Standard Model coupled to gravity. The Higgs mass parameter can be relaxed to a correct value due to the four-form coupling to the Higgs field and it stops changing due to an extremely suppressed transition probability from the observed cosmological constant to AdS space. We first introduce a non-minimal four-form coupling to gravity and discuss the role of a new scalar field as the inflaton and the conditions for a successful reheating at the end of relaxation.

description: Reaching Performance Scale for Stroke (RPSS) evaluates the upper limb reach-to-grasp movement quality and compensatory movements. The objective of the study was to test the reliability, construct validity, and interpretability of the Brazilian-Portuguese RPSS. Fifty-one individuals (mean age 62 ± 10.8 years), with acute-to-chronic stroke (range: 1–300 months) were video recorded while performing a reach-to-grasp task of a cone placed both close and far from the individual. Their degree of motor impairment ranged from 4 to 59 points in the Fugl-Meyer scale. Reaching Performance Scale for Stroke showed excellent intra- (ICC2,1 = 1.00) and interrater (ICC2,1 = 0.98–0.99) reliability, and redundant internal consistency (Cronbach’s α = 0.98). The construct validity between RPSS and Fugl-Meyer scale was strong (Spearman rho = 0.88–0.89; p Reaching Performance Scale for Stroke showed excellent reliability and redundant internal consistency. The construct validity with the Fugl-Meyer scale was strong. Reaching Performance Scale for Stroke was able to discriminate individuals with different levels of upper limb impairment.IMPLICATIONS FOR REHABILITATIONPost-stroke individuals develop compensatory strategies to perform reaching movements with the paretic upper limb.The Reaching Performance Scale for Stroke provides a quantitative and qualitative evaluation of the reach-to-grasp movement.The Reaching Performance Scale for Stroke is suitable for use with Brazilian-Portuguese speakers and has adequate reliability and validity.

description: A new indicator of farm income dependence is developed for identifying differences in resource allocation among farm households. Analysis of farm household data between 1996 and 2006 identifies the index as being more informative and indicative of structural responses than the typical reliance on shares of farm income in the total for the representative household. Extensions of the index and complementarities with other measures are straightforward and offer potential valuable insight into coming trends in U.S. agriculture as the farm household population responds to higher prices induced by the biofuel boom.

description: We discuss the BFKL approach to processes with large momentum transferred through a rapidity gap. The Mueller and Tang scheme to the BFKL non-forward parton-parton elastic scattering amplitude at large $t$, is extended to include higher conformal spins. The new contributions are found to decrease with increasing energy, as follows from the gluon reggeisation phenomenon, and to vanish for asymptotically high energies. However, at moderate energies and high $|t|$, the higher conformal spins dominate the amplitude. We illustrate the effects by studying the production of two high $E_T$ jets separated by a rapidity gap at HERA energies. In a simplified framework, we find excellent agreement with the HERA photoproduction data once we incorporate the rapidity gap survival probability against soft rescattering effects. We emphasize that measurements of the analogous process in electroproduction may probe different summations over conformal spins.

description: Rice is one of the major food crop produced and consumed in Togo. Although it has the potential to produce more than it needs, Togo imports nearly 50 percent of domestic consumption. Realizing its potential for increasing household income and food security, the government has been encouraging domestic production through various farm support programs since early 1990s. Although these programs have achieved some success in increasing production, it has failed to keep up with the soaring market demand. Moreover, despite consistent efforts from the government, only about 20 percent of the land suitable for rice cultivation was producing paddy until 2007. Although most native varieties are in high demand and receive significantly higher prices than imported varieties, factors such as limited access to modern inputs, lack of market information, and rising cheap imports are the primary constraints for steady growth in domestic rice production. In this light, this study aims to evaluate the impact of rising imports on domestic rice production in Togo. A source differentiated import demand function is used to evaluate the impact of importing broken, brown, and milled rice on domestic production. Preliminary results show that imported broken rice is considered as an inferior good in Togo.

description: We consider the 2-dimensional random matching problem in $\mathbb{R}^2.$ In a challenging paper, Caracciolo et. al. arXiv:1402.6993 on the basis of a subtle linearization of the Monge Ampere equation, conjectured that the expected value of the square of the Wasserstein distance, with exponent $2,$ between two samples of $N$ uniformly distributed points in the unit square is $\log N/2πN$ plus corrections, while the expected value of the square of the Wasserstein distance between one sample of $N$ uniformly distributed points and the uniform measure on the square is $\log N/4πN$. These conjectures has been proved by Ambrosio et al. arXiv:1611.04960. Here we consider the case in which the points are sampled from a non uniform density. For first we give formal arguments leading to the conjecture that if the density is regular and positive in a regular, bounded and connected domain $Λ$ in the plane, then the leading term of the expected values of the Wasserstein distances are exactly the same as in the case of uniform density, but for the multiplicative factor equal to the measure of $Λ$. We do not prove these results but, in the case in which the domain is a square, we prove estimates from above that coincides with the conjectured result.

description: The mass--energy formula of black holes implies that up to 50% of the energy can be extracted from a static black hole. Such a result is reexamined using the recently established analytic formulas for the collapse of a shell and expression for the irreducible mass of a static black hole. It is shown that the efficiency of energy extraction process during the formation of the black hole is linked in an essential way to the gravitational binding energy, the formation of the horizon and the reduction of the kinetic energy of implosion. Here a maximum efficiency of 50% in the extraction of the mass energy is shown to be generally attainable in the collapse of a spherically symmetric shell: surprisingly this result holds as well in the two limiting cases of the Schwarzschild and extreme Reissner-Nordström space-times. Moreover, the analytic expression recently found for the implosion of a spherical shell onto an already formed black hole leads to a new exact analytic expression for the energy extraction which results in an efficiency strictly less than 100% for any physical implementable process. There appears to be no incompatibility between General Relativity and Thermodynamics at this classical level.

description: Malting is the process of turning raw grains into a product that can be used in brewing, distilling, and baking, to name a few end products. Currently, a small number of large companies supply malts at a large scale, particularly to brewers. As the craft beer industry has continued to expand over the past 20 years in the US, however, micro-malters have emerged providing smaller batches of specialized malts, primarily for regional craft brewers. The purpose of this study is to assess the feasibility of such a venture given market conditions in the state of Georgia. The feasibility of a micro-malting facility in northeast Georgia is dependent on a number of factors. In this study we examine the current micro-malting industry, potential demand for commercial malts in Georgia and consumer demand for specialty malts.

description: We establish a simple formula for the minimal dimension of operators leading to any helicity amplitude. It eases the systematic enumeration of independent operators from the construction of massless non-factorizable on-shell amplitudes. Little-group constraints can then be solved algorithmically for each helicity configuration to extract a complete set of spinor structures with lowest dimension. Occasionally, further reduction using momentum conservation, on-shell conditions and Schouten identities is required. A systematic procedure to account for the latter is presented. Dressing spinor structures with dot products of momenta finally yields the independent Lorentz structures for each helicity amplitude. We apply these procedures to amplitudes involving particles of spins 0,1/2,1,2. Spin statistics and elementary selection rules due to gauge symmetry lead to an enumeration of operators involving gravitons and standard-model particles, in the effective field theory denoted GRSMEFT. We also list the independent spinor structures generated by operators involving standard-model particles only. In both cases, we cover operators of dimension up to eight.

description: Pork consumption accounts for more than 60% of total meat consumption in China. China’s rapid economic growth, expanding middle class and continuous urbanization is increasing the demand for pork and importance in stabilizing China's pork market. This also creates an opportunity for foreign pork producers to export more pork to China. How can this be done? Foreign direct investment is one solution when trade barriers exist. This case study explores the reasons why China's Shuanghui International acquired the U.S. based, Smithfield Foods. Analysis shows that the success of the two companies’ merger depends upon the establishment of an efficient transnational pork supply chain. This case study can be used for Bachelor of Science and Master of Science students in international economics, agribusiness and agricultural marketing courses. It will also be helpful to business managers who want to export more agricultural goods to China.

The extensive connections to other models of statistical phyics are discussed. We investigate our model on a hierarchical lattice which allows an exact asymptotic renormalization treatment. A surprisingly close analogy is observed between the simulation results on the regular and the hierarchical lattices. The dynamics is characterized by the breakdown of ergodicity, by unusual system size effects in the development of the average density as well as by the age distribution, the latter showing multifractal properties.

Publisher: name: Zenodo
Year: 2025

description: ABSTRACT

This study explores the promotion of diversity using the UK Corporate Governance Code 2018 and makes a comparison of listed and non-listed supermarkets in the United Kingdom in the last four years. The samples drawn were from three listed and three non-listed supermarkets in relation to gender diversity on the board, gender pay gap, and diversity and inclusion among employees.

This study adopted the post-positivism paradigm, which generally involved the use of a quantitative mode of inquiry. The design adopted a comparative survey design for the study and data were collected from secondary sources mostly from financial reports, gender pay gap reports, websites, and press releases from the selected supermarkets. Six of the supermarkets (listed and non-listed) were from the available list of UK supermarkets using a stratified sampling technique. The study also adopted the use of statistics such as frequency, percentages, and charts for data analysis.

The result of the first research question revealed that the UK Corporate Governance Code 2018 has not consistently promoted gender diversity among most supermarkets, although listed supermarkets showed better efforts in achieving gender diversity on the board than the non-listed supermarkets in the last four years. The result of the second research showed that the UK Corporate Governance Code 2018 is effective in reducing gender pay gaps among listed supermarkets when compared to the non-listed supermarkets in the last four years. Finally, the UK Corporate Governance Code 2018 promoted diversity among employees in listed supermarkets but remained inconsistent in its implementation in non-listed supermarkets in the last four years.

Overall, the study provides insight into how the recent UK code impacts the retail industry with a special focus on supermarkets.

Keywords: Corporate Governance, UK Corporate Governance Code 2018, Gender Diversity, Gender Pay Gap, Diversity, and Inclusion among Employees, Listed and Non-listed Supermarkets.

description: This paper presents a specific man-in-the-middle exploit: Ambient Tactical Deception (ATD) in online communication, realized via a malicious web browser extension. Extensions manipulate web content in unobtrusive ways as ambient intermediaries of the overall browsing experience. In our previous work, we demonstrated that it is possible to employ tactical deception by making covert changes in the text content of a web page, regardless of the source. In this work, we investigated the application of ATD in a web-based email discourse where the objective is to manipulate the interpersonal perception without the knowledge of the involved parties. We focus on web-based email text because it is asynchronous and usually revised for clarity and politeness. Previous research has demonstrated that people's perception of politeness in online communication is based on three factors: the degree of imposition, the power of the receiver over the sender, and the social distance between them. We interviewed participants about their perception of these factors to establish the plausibility of ATD for email discourse. The results indicate that by covertly altering the politeness strategy in an email, it is possible for an ATD attacker to manipulate the receiver's perception on all of the politeness factors. Our findings support the Brown and Levinson's politeness theory and Walther's hyperpersonal model of email communication.

Two-photon linewidth of light "stopping" via electromagnetically induced transparency

Year: 2002

description: We analyze the two-photon linewidth of the recently proposed adiabatic transfer technique for ``stopping'' of light using electromagnetically induced transparency (EIT). We shown that a successful and reliable transfer of excitation from light to atoms and back can be achieved if the spectrum of the input probe pulse lies within the initial transparency window of EIT, and if the two-photon detuning $δ$ is less than the collective coupling strength (collective vacuum Rabi-frequency) $g\sqrt{N}$ divided by $\sqrt{γT}$, with $γ$ being the radiative decay rate, $N$ the effective number of atoms in the sample, and $T$ the pulse duration. Hence in an optically thick medium light ``storage'' and retrieval is possible with high fidelity even for systems with rather large two-photon detuning or inhomogeneous broadening.

description: We report the structural, magnetic, and magnetocaloric properties of Co$_2$Cr$_{1-x}$Ti$_x$Al ($x=$ 0--0.5) Heusler alloys for spintronic and magnetic refrigerator applications. Room temperature X-ray diffraction and neutron diffraction patterns along with Rietveld refinements confirm that the samples are of single phase and possess a cubic structure. Interestingly, magnetic susceptibly measurements indicate a second order phase transition from paramagnetic to ferromagnetic where the Curie temperature (T$_{\rm C}$) of Co$_2$CrAl increases from 330~K to 445~K with Ti substitution. Neutron powder diffraction data of the $x=$ 0 sample across the magnetic phase transition taken in a large temperature range confirm the structural stability and exclude the possibility of antiferromagnetic ordering. The saturation magnetization of the $x=$ 0 sample is found to be 8000~emu/mol (1.45~$μ_{\rm B}$/{\it f.u.}) at 5~K, which is in good agreement with the value (1.35$\pm$0.05~$μ_{\rm B}$/{\it f.u.}) obtained from the Rietveld analysis of the neutron powder diffraction pattern measured at temperature of 4~K. By analysing the temperature dependence of the neutron data of the $x=$ 0 sample, we find that the change in the intensity of the most intense Bragg peak (220) is consistent with the magnetization behavior with temperature. Furthermore, an enhancement of change in the magnetic entropy and relative cooling power values has been observed for the $x=$ 0.25 sample. Interestingly, the critical behavior analysis across the second order magnetic phase transition and extracted exponents ($β\approx$ 0.496, $γ\approx$ 1.348, and $δ\approx$ 3.71 for the $x=$ 0.25 sample) suggest the presence of long-range ordering, which deviates towards 3D Heisenberg type interactions above T$_{\rm C}$, consistent with the interaction range value $σ$.

description: In this work, polydopamine-modified carbon fiber-supported PdNi nanoparticles were facially prepared and used in the Suzuki cross-coupling reaction with a high catalytic activity. The introduction of nickel increases the electron density around palladium and the catalytic activity. At the same time, comparing the effect of high-temperature carbonization, it is found that high temperature can enhance the electron transfer between the metal and the carrier and make the metal and the carrier bond more firmly. Provide new ideas for fixing nanoparticles in the future.

description: A series of new 1,3-thiazole derivatives of maleopimaric acid 6a–f, 7a–f were synthesized and evaluated for anticancer, antibacterial and antifungal activities. Evaluation of cytotoxic activity against human embryonic kidney 293 cells (HEK293), human neuroblastoma cell line (SH-SY5Y), hepatocellular carcinoma cell line (HepG2) and human T-cell lymphoblast-like line (Jurkat), showed that introduction of the aminothiazole fragment at position 6 of the diterpenoid molecule leads to decrease of cell viability. Substance 3 was found to be the most active against all tested cell lines, inhibiting cell viability with IC50 values in the range of 2–24 μM. The structure–activity relationship of these compounds was studied and the results show that the compounds 6c and 7e exhibited in vitro antifungal activity against Candida albicans and also possessed antibacterial profile against Enterobacter aerogenes, Klebsiella pneumoniae, Staphylococcus aureus, Streptococcus pyogenes, Escherichia coli and Proteus vulgaris.

description: We consider decay of an initial density or current perturbation at finite temperature $T$ near a quantum critical point with emergent Lorentz invariance. We argue that decay of perturbations with wavenumbers $k \gg T$ (in natural units) is a good testing ground for holography---existence of a dual gravitational description---in experimentally accessible systems. The reason is that, computed holographically, the decay rate at large $k$ depends only on the leading correction to the metric near the boundary, and that is quite universal. In the limit of zero detuning (when the temperature is the only dimensionful parameter), the result is a scaling law for the decay rate, with the exponent that depends only on the dimensionality. We show that this follows from an analytical argument and is borne out by a numerical study of quasinormal modes.

A quantum stochastic approach to the spectrum of a two-level atom
Creators: name: Barchielli, Alberto

Publisher: name: arXiv
Year: 2002
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: By means of quantum stochastic calculus we construct a model for an atom with two degenerate levels and stimulated by a laser and we compute its fluorescence spectrum; let us stress that, once the model for the unitary atom-field dynamics has been given, then the spectrum is computed without further approximations. If only the absorption/emission term is included in the interaction, we reobtain the Mollow spectrum in the case of a monochromatic laser and the Kimble-Mandel spectrum in the case of a "phase diffusion model" for a non monochromatic laser. However, our model can describe also another type of light scattering, a "direct scattering" due to the response of the atom as a whole, which we expect to be small, but which interferes with the scattering due to the absorption/emission channel. When both the scattering channels are introduced we obtain a modification of the Mollow-Kimble-Mandel spectrum, which shares the main features with the usual case, but which presents some asymmetries even in the case of no detuning.

description: Entanglement can be considered as a special quantum correlation, but not the only kind. Even for a separable quantum system, it is allowed to exist non-classical correlations. Here we propose two dissipative schemes for generating a maximally correlated state of two qubits in the absence of quantum entanglement, which was raised by [F. Galve, G. L. Giorgi, and R. Zambrini, {\color{blue}Phys. Rev. A {\bf 83}, 012102 (2011)}]. These protocols take full advantages of the interaction between four-level atoms and strongly lossy optical cavities. In the first scenario, we alternatively change the phases of two classical driving fields, while the second proposal introduces a strongly lossy coupled-cavity system. Both schemes can realize all Lindblad terms required by the dissipative dynamics, guaranteeing the maximally quantum dissonant state to be the unique steady state for a certain subspace of system. Moreover, since the target state is a mixed state, the performance of our method is evaluated by the definition of super-fidelity $G(ρ_{1},ρ_{2})$, and the strictly numerical simulations indicate that fidelity outstripping $99\%$ of the quantum dissonant state is achievable with the current cavity quantum electrodynamics parameters.

Maximally localized states and causality in non commutative quantum theories

Publisher: name: arXiv
Year: 2001
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We give simple representations for quantum theories in which the position commutators are non vanishing constants. A particular representation reproduces results found using the Moyal star product. The notion of exact localization being meaningless in these theories, we adapt the notion of ``maximally localized states'' developed in another context . We find that gaussian functions play this role in a 2+1 dimensional model in which the non commutation relations concern positions only. An interpretation of the wave function in this non commutative geometry is suggested. We also analyze higher dimensional cases. A possible incidence on the causality issue for a Q.F.T with a non commuting time is sketched.

Diffeomorphisms and spin foam models

description: We study the action of diffeomorphisms on spin foam models. We prove that in 3 dimensions, there is a residual action of the diffeomorphisms that explains the naive divergences of state sum models. We present the gauge fixing of this symmetry and show that it explains the original renormalization of Ponzano-Regge model. We discuss the implication this action of diffeomorphisms has on higher dimensional spin foam models and especially the finite ones.

Electronic transport through correlated electron systems with nonhomogeneous charge orderings

description: The spinless Falicov-Kimball model exhibits outside the particle-hole symmetric point different stable nonhomogeneous charge orderings. These include the well known charge stripes and a variety of orderings with phase separated domains, which can significantly influence the charge transport through the correlated electron system. We show this by investigating a heterostructure, in which the Falicov-Kimball model on a finite two-dimensional lattice is located between two noninteracting semi-infinite leads. We use a combination of nonequilibrium Green's functions techniques with a sign-problem-free Monte Carlo method for finite temperatures or a simulated annealing technique for the ground state to address steady-state transport through the system. We show that different ground-state phases of the central system can lead to simple metallic-like or insulating charge transport characteristics, but also to more complicated current-voltage dependencies reflecting a multi-band character of the transmission function. Interestingly, with increasing temperature, the orderings tend to form transient phases before the system reaches the disordered phase. This leads to nontrivial temperature dependencies of the transmission function and charge current.

description: This case offers students the simulation of providing consulting to a small, newly-formed and struggling dairy processor in the developing country of Tajikistan. The task is to conduct a profitability analysis using data provided by the firm. This can be accomplished by calculating the contribution margin of each product and estimating monthly break-even production levels for various scenarios. The information, combined with the background provided in the case, can be used to develop marketing and production strategies. Completing this analysis requires working with imperfect data and making appropriate assumptions. The case highlights the reality of challenges faced by small-scale agribusinesses in emerging economies.
