description: We report on a measurement of the asymmetry in the scattering of transversely polarized electrons off unpolarized protons, A$_\perp$, at two Q$^2$ values of \qsquaredaveragedlow (GeV/c)$^2$ and \qsquaredaveragedhighII (GeV/c)$^2$ and a scattering angle of $30^\circ < θ_e < 40^\circ$. The measured transverse asymmetries are A$_{\perp}$(Q$^2$ = \qsquaredaveragedlow (GeV/c)$^2$) = (\experimentalasymmetry alulowcorr $\pm$ \statisticalerrorlow$_{\rm stat}$ $\pm$ \combinedsyspolerrorlowalucor$_{\rm sys}$) $\times$ 10$^{-6}$ and A$_{\perp}$(Q$^2$ = \qsquaredaveragedhighII (GeV/c)$^2$) = (\experimentalasymme tryaluhighcorr $\pm$ \statisticalerrorhigh$_{\rm stat}$ $\pm$ \combinedsyspolerrorhighalucor$_{\rm sys}$) $\times$ 10$^{-6}$. The first errors denotes the statistical error and the second the systematic uncertainties. A$_\perp$ arises from the imaginary part of the two-photon exchange amplitude and is zero in the one-photon exchange approximation. From comparison with theoretical estimates of A$_\perp$ we conclude that $π$N-intermediate states give a substantial contribution to the imaginary part of the two-photon amplitude. The contribution from the ground state proton to the imaginary part of the two-photon exchange can be neglected. There is no obvious reason why this should be different for the real part of the two-photon amplitude, which enters into the radiative corrections for the Rosenbluth separation measurements of the electric form factor of the proton.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: We demonstrate that the configurational temperature formalism can be derived from the classical hypervirial theorem, and introduce a hierarchy of hyperconfigurational temperature definitions, which are particularly well suited for experimental studies. We then use these analytical tools to probe the electrostatic interactions in monolayers of charge-stabilized colloidal spheres confined by parallel glass surfaces. The configurational and hyperconfigurational temperatures, together with a novel thermodynamic sum rule, provide previously lacking self-consistency tests for interaction measurements based on digital video microscopy, and thereby cast new light on controversial reports of confinement-induced like-charge attractions. We further introduce a new method for measuring the pair potential directly that uses consistency of the configurational and hyperconfigurational temperatures as a set of constraints for a model-free search.

description: We derive a Noether current for the Eulerian variational principle of ideal non-barotropic magnetohydrodynamics (MHD). It was shown previously that ideal non-barotropic MHD is mathematically equivalent to a five function field theory with an induced geometrical structure in the case that field lines cover surfaces and this theory can be described using a variational principle. Here we use various symmetries of the flow to derive topological constants of motion through the derived Noether current and discuss their implication for non-barotropic MHD.

The quantum Hamiltonians have been transformed in the form of the one variable differential equation and the conditions for its solvability have been discussed.

As an application, solutions of the modified Jaynes-Cummings and two-level Jahn Teller Hamiltonians are studied.
Accretion flows in early-type galaxies and CMB experiments

description: We investigate the possible contribution from the emission of accretion flows around supermassive black holes in early type galaxies to current measurements of the Cosmic Microwave Background (CMB) at radio frequencies. We consider a range of luminosities suggested by targeted radio observations and accretion models and compute the residual contribution of these sources to the spectrum and bispectrum of the observed CMB maps. As for high-resolution CMB experiments, we find that the unresolved component of these sources could make up to ~40-50% of the observed CBI and BIMA power spectrum at l > 2000. As a consequence, the inferred sigma_8^{SZ} value could be biased high by up to 6-7%. As for all sky experiments, we find that the contribution of accretion-flow sources to the WMAP bispectrum is at the 2-3 per cent level at most. At the flux limit that Planck will achieve, however, these sources may contribute up to 15 per cent of the bispectrum in the 60-100 GHz frequency range. Moreover, Planck should detect hundreds of these sources in the 30-300 GHz frequency window. These detections, possibly coupled with galaxy type confirmation from optical surveys, will allow number counts to put tighter constraints on early-type galaxies radio luminosity and accretion flows properties. These sources may also contribute up to the 30 per cent level to the residual radio sources power spectrum in future high-resolution SZ surveys (like ACT or APEX) reaching mJy flux limits.

description: Preparing and observing quantum states of nanoscale particles is a challenging task with great relevance for quantum technologies and tests of fundamental physics. In contrast to atomic systems with discrete transitions, nanoparticles exhibit a practically continuous absorption spectrum and thus their quantum dynamics cannot be easily manipulated. Here, we demonstrate that charged nanoscale dielectrics can be artificially endowed with a discrete level structure by coherently interfacing their rotational and translational motion with a superconducting qubit. We propose a pulsed scheme for the generation and read-out of motional quantum superpositions and entanglement between several levitated nanoparticles, providing an all-electric platform for networked hybrid quantum devices.

description: The revision of the Author's results with respect to possibility of existence of the so-called Euclidian cycles in cosmological evolution of a system of Higgs scalar fields has been performed. The assumption of non-negativity of the Universe's extension velocity, which contradicts in certain cases to complete system of Einstein equations, has been removed. It has been shown that in cases when effective energy of the system tends to zero, a smooth transition of the model to the range of negative values of the extension velocity occurs, i.e. it occurs the transition to collapse stage rather than winding of the phase trajectories on the boundary of prohibited area. This process has been researched with a help of numerical simulation methods for the model based on classical scalar Higgs field.

We find that if the amplitude of the density fluctution is variable, the holographic dark energy fares better than the cosmological constant. More generally, the anthropic predictions agree better with observation for dark energy with $w_\d=p_\d/ρ_\d$ decreasing over time.

description: Brain functions have been shown to be affected by external stimuli. Low- Level-Light Therapy (LLLT) using nearinfrared photons is one of the effective ways to modulate the hemodynamic activities in the brain. However, the biphasic hormetic dose-response where bioenergetics are stimulated at a low dose and inhibited at a high dose is well observed in all photon stimulations. The amount of photon energy delivered to the brain are affected by the wavelength as well as the multilayered head structure with variations of optical parameters (OPs). A real 3D volume head model is built for each participant in this study, and the boundary conditions of each OP in each layer is considered. The Monte Carlo simulation with wavelengths ranging from 650 nm to 1064 nm is implemented to investigate the energy delivered to the brain under different radiation profiles. Results show that 1064-nm photons penetrate deeper than 810-nm photons except for scalp absorption at the lower bound due to low melanin content. Collimated-beam radiation is better than diverging-beam due to a more uniform intensity distribution at the scalp surface. Further research to optimize LLLT dosage for each individual is imperative due to the high inter-person variability in structure and OPs. In addition, EEG measures voltage fluctuations resulting from ionic current within the neurons of the brain. Because ATP is the major energy unit consumed by the ion pump and gate, PhotoBioModulation(PBM) will theoretically affect EEG. We establish the relationship between PBM and EEG demonstrated that PBM could increase resting-state alpha, beta, and gamma power by an increment of prefrontal blood oxygen level.

description: The aim of the study was to estimate price advantages of the Polish food producer at the processing level compared to the German producers in 2012 based on 2002. Conducted analysis of diversifying food prices in Poland and in Germany shows that Polish producers still have meaning the majority price towards German producers, both on the level of the producer, as well as the consumer. The biggest advantage we achieved so far in the poultry meat market and meat products, dairy products and cereals and confectionery, as well as juices, soft drinks and mineral waters and tobacco. Currently undoubtedly progressing process of price equalization of both the producer and the consumer on the Polish and German, and applies to all products (animal, vegetable and highly processed). The process of price equalization is one of the factors that forced Polish food producers to seek sources of non-price competitiveness.

description: The pituitary-thyroid relationship has been studied in vitro in the stingray, Dasyatis sabina. The addition of mammalian TSH failed to stimulate incubated stingray thyroid glands, but mammalian TSH did stimulate teleost thyroids in parallel experiments. Homogenates of whole D. sabina pituitary significantly increased the release of thyroxine from the stingray thyroid, while homogenates of whole teleost pituitary had no effect. The greatest thyroid stimulating activity was found in the ventral lobe of the pars distalis. No seasonal or sexual differences were observed in the relationship between thyroid weight and animal weight. The ratio of total iodine to thyroxine iodine did not vary between sexes or between stimulated and unstimulated glands in vitro. It was concluded that the thyroid is associated with reproduction because (1) thyrotropic activity was located in the region known to contain gonadotrophic activity, and (2) the spontaneous rate of thyroxine release from incubated thyroid glands increased in females at the time of sexual maturation (release rates of juvenile males, adult males, and adult females were similar). There were no changes in the spontaneous rates of thyroxine release that could be correlated with seasonal changes in environmental salinity or temperature or with migratory movements

The research was conducted in the period from 1999 to 2008, distinguishing for each year and the number of persons in the household. The results indicate that all income elasticity coefficient are greater than zero. In addition, in the analyzed period expenditure on transportation, expenditure on culture and recreation, and other expenditures on goods and services have income elasticity coefficient close to 1. In addition, with the increase of the number of people in the household, expenditure on health and education are reduced, which may mean that these needs are unmet. In the research, the data from the Household Budget Survey conducted by the Central Statistical Office were used.

description: Data sharing for medical research has been difficult as open-sourcing clinical data may violate patient privacy. Traditional methods for face de-identification wipe out facial information entirely, making it impossible to analyze facial behavior. Recent advancements on whole-body keypoints detection also rely on facial input to estimate body keypoints. Both facial and body keypoints are critical in some medical diagnoses, and keypoints invariability after de-identification is of great importance. Here, we propose a solution using deepfake technology, the face swapping technique. While this swapping method has been criticized for invading privacy and portraiture right, it could conversely protect privacy in medical video: patients' faces could be swapped to a proper target face and become unrecognizable. However, it remained an open question that to what extent the swapping de-identification method could affect the automatic detection of body keypoints. In this study, we apply deepfake technology to Parkinson's disease examination videos to de-identify subjects, and quantitatively show that: face-swapping as a de-identification approach is reliable, and it keeps the keypoints almost invariant, significantly better than traditional methods. This study proposes a pipeline for video de-identification and keypoint preservation, clearing up some ethical restrictions for medical data sharing. This work could make open-source high quality medical video datasets more feasible and promote future medical research that benefits our society.

This quantity cannot be measured directly. However, it can be computed within a given theory. As an example, we demonstrate validity of the sum rule in QED at tree level--the renowned Schwinger's correction to the anomalous magnetic moment is readily reproduced. In the case of the strong interactions, we also consider the calculation of the nucleon magnetic moment within chiral theories.

description: The aim of the study was to estimate the technical potential of cereal straw. Based on CSO data from the National Agricultural Census of 2010 was characterised regional difference in the share of cereals in sowing area. Estimation of the theoretical and technically potential of straw allows one to obtain information about the opportunities to meet the energy needs for the local district (region). The technical potential of straw was calculated taking into account the reuse of straw in agriculture (litter, feed, straw incorporation). The total straw surplus, which can be used for energy purposes amounted to more than 12.5 million tons. The technical potential is highly diversified in individual local districts and ranges from 0 to about 20 thousand tons. Significant quantities of straw for energy purposes can be designed in the local districts with the dominance of large farms.

description: A detailed analysis of dynamics of cosmological models based on $R^{n}$ gravity is presented. We show that the cosmological equations can be written as a first order autonomous system and analyzed using the standard techniques of dynamical system theory. In absence of perfect fluid matter, we find exact solutions whose behavior and stability are analyzed in terms of the values of the parameter $n$. When matter is introduced, the nature of the (non-minimal) coupling between matter and higher order gravity induces restrictions on the allowed values of $n$. Selecting such intervals of values and following the same procedure used in the vacuum case, we present exact solutions and analyze their stability for a generic value of the parameter $n$. From this analysis emerges the result that for a large set of initial conditions an accelerated expansion is an attractor for the evolution of the $R^n$ cosmology. When matter is present a transient almost-Friedman phase can also be present before the transition to an accelerated expansion.

In addition to it, the authors failed to comment on the possibility of multiple solutions for every set of quantum numbers.

description: A unified set of hydrodynamic equations describing condensed phases of matter with broken continuous symmetries is derived using a generalization of the statistical-mechanical approach based on the local equilibrium distribution. The dissipativeless and dissipative parts of the current densities and the entropy production are systematically deduced in this approach by expanding in powers of the gradients of the macrofields. Green-Kubo formulas are obtained for all the transport coefficients. The results apply to both crystalline solids and liquid crystals. The consequences of microreversibility and spatial symmetries are investigated, leading to the prediction of cross effects resulting from Onsager-Casimir reciprocal relations.

A case study in the conceptual design of an anodized aluminium cladding system for a steel torus structure
Creators: name: Fitch, Devan Carless
Publisher: name: University of British Columbia
Year: 2011

description: Typically, structural systems, such as cladding panels are used to achieve a desired architectural appearance, enclose building envelopes and act as barriers to ingress of the external environment. Due to the large surface area of such applications, efficient design of these panels is of paramount importance, if a cost effective solution is to be achieved. Existing structures utilizing cladding systems typically consist of flat rectangular panels enclosing a regular and rectangular building. For this design project, the structure to be enclosed is a torus structure, and in order to achieve an aesthetic appearance which is acceptable to the client, both curved and flat panels are investigated. Through careful review of available literature, parasitic cladding panels (these do not resist global loads) are selected over a stressed skin (architectural fabric) structural solution due to the highly non-linear and hence complex behaviour of the latter coupled with the fact that the particular geometry of the structure considered in this project does not readily lend itself to implementation of a stressed skin solution. Anodized aluminum is selected over composite materials for the cladding panels, due to the higher confidence level in achieving the desired aesthetic appearance of the panels, and the long-term durability of this appearance with this material. The design of flat cladding panels is relatively simple and there are many analytical solutions available in the literature. However, there is little information that can be found in the literature regarding the conceptual design of curved cladding panels. The structural design of curved panels subject to environmental loading such as uniform normal pressure and thermal gradients is complex due to their nonlinear behavior and susceptibility to buckling. A finite-element (FE) investigation into the influence of panel parameters including; geometry, support conditions and stiffening elements on design efficiency is conducted. From the results of the investigation, a reasonable approach to the design of curved aluminum panels is outlined; starting with analytical methods of structural analysis o f un-stiffened panels and progressing to finite element analysis of longitudinally and radially stiffened panels with discrete supports. Throughout this thesis, charts are developed which will simplify and direct future analysis. They might be helpful for the conceptual design of these panels. Areas of concern and of particular importance are identified, allowing these aspects to be considered at the outset of a project, when decisions and changes can be made more readily and with fewer consequences in terms of budget and schedule over-runs.

description: The purpose of this article is to identify the current state of the domestic market of legume native and an indication of the main limitations in its development. To attain the required carry out research into strengths and weaknesses, and the opportunities and threats of native legumes market in Poland. It concluded that over the years there has been a systematic increase of area planted fodder legumes, however, do not increase the volume of production of the raw material. Pointed to competition from the soybean market as a product substitution, as well as the occurrence of, among other things: territorial dispersion, small scale production of the raw material and the lack of liquidity on the market. It was recognized that these are the factors that led to the marginalization of the domestic market of native legumes.

description: The present article investigates the role of heavy nuclear clusters and weakly bound light nuclear clusters based on a newly developed equation of state for core collapse supernova studies. A novel approach is brought forward for the description of nuclear clusters, taking into account the quasiparticle approach and continuum correlations. It demonstrates that the commonly employed nuclear statistical equilibrium approach, based on non-interacting particles, for the description of light and heavy clusters becomes invalid for warm nuclear matter near the saturation density. This has important consequences for studies of core collapse supernovae. To this end, we implement this nuclear equation of state provided for arbitrary temperature, baryon density and isospin asymmetry, to spherically symmetric core collapse supernova simulations in order to study the impact on the dynamics as well as on the neutrino emission. For the inclusion of a set of weak processes involving light clusters the rate expressions are derived, including medium modifications at the mean field level. A substantial impact from the inclusion of a variety of weak reactions involving light clusters on the post bounce dynamics nor on the neutrino emission could not be found.

description: Recent developments in the QCD description of the pion structure are reviewed. The CLEO pion-photon transition data analysis favors a distribution amplitude for the pion that is double-humped but endpoint-suppressed. After a short outline of the derivation of this amplitude from QCD sum rules with nonlocal condensates, we present the fully fledged analysis of the CLEO data prefaced by predictions for the $F^{γρπ}$ form factor and commenting on the inherent theoretical uncertainties due to higher twists and NNLO perturbative corrections. We supplement our discussion by considering within QCD factorization theory, the electromagnetic pion form factor at NLO accuracy on one hand, and diffractive di-jets production on the other, comparing our predictions with the respective experimental data from JLab and the Fermilab E791 collaboration. In all cases, the agreement is impressive.

Can Primal Methods Outperform Primal-dual Methods in Decentralized Dynamic Optimization?

description: In this paper, we consider the decentralized dynamic optimization problem defined over a multi-agent network. Each agent possesses a time-varying local objective function, and all agents aim to collaboratively track the drifting global optimal solution that minimizes the summation of all local objective functions. The decentralized dynamic optimization problem can be solved by primal or primal-dual methods, and when the problem degenerates to be static, it has been proved in literature that primal-dual methods are superior to primal ones. This motivates us to ask: are primal-dual methods necessarily better than primal ones in decentralized dynamic optimization? To answer this question, we investigate and compare convergence properties of the primal method, diffusion, and the primal-dual approach, decentralized gradient tracking (DGT). Theoretical analysis reveals that diffusion can outperform DGT in certain dynamic settings. We find that DGT and diffusion are significantly affected by the drifts and the magnitudes of optimal gradients, respectively. In addition, we show that DGT is more sensitive to the network topology, and a badly-connected network can greatly deteriorate its convergence performance. These conclusions provide guidelines on how to choose proper dynamic algorithms in various application scenarios. Numerical experiments are constructed to validate the theoretical analysis.

description: The low-energy part of the vibration spectrum in KNbO$_3$ was studied by cold neutron inelastic scattering in the cubic phase. In addition to acoustic phonons, we observe strong diffuse scattering, which consists of two components. The first one is quasi-static and has a temperature-independent intensity. The second component appears as quasi-elastic scattering in the neutron spectrum indicating a dynamic origin. From analysis of the inelastic data we conclude that the quasi-elastic component and the acoustic phonon are mutually coupled. The susceptibility associated with the quasi-elastic component grows as the temperature approaches T$_C$.

description: The aim of the study was to identify and evaluate instruments of competition applied by agricultural businesses using the Agricultural Property Resources Of The State Treasury. A survey was conducted among 87 farms located in the province of Warmia and Mazury. The analysis shows that the most important instruments of competition were the price and the quality of the product. The use of instruments related to the quality of the products was often indicated by the owners of very large farms. Among these entities, an important instrument of competition was the price, but as a complement to non-price competitiveness factors.
