description: X-ray and electron diffraction measurements on the metal-insulator (M-I) transition compound PrRu$_4$P$_{12}$ have revealed the emergence of a periodic ordering of charge density around the Pr atoms. It is found that the ordering is associated with the onset of a low temperature insulator phase. These conclusions are supported by the facts that the space group of the crystal structure transforms from Im$\bar{3}$ to Pm$\bar{3}$ below the M-I transition temperature and also that the temperature dependence of the superlattice peaks in the insulator phase follows the squared BCS function. The M-I transition could be originated from the perfect nesting of the Fermi surface and/or the instability of the $f$ electrons.

description: When a system is thermally coupled to only a small part of a larger bath, statistical fluctuations of the temperature (more precisely, the internal energy) of this "sub-bath" around the mean temperature defined by the larger bath can become significant. We show that these temperature fluctuations generally give rise to 1/f-like noise power spectral density from even a single two-level system. We extend these results to a distribution of fluctuators, finding the corresponding modification to the Dutta-Horn relation. Then we consider the specific situation of charge noise in silicon quantum dot qubits and show that recent experimental data [E. J. Connors, et al., Phys. Rev. B 100, 165305 (2019)] can be modeled as arising from as few as two two-level fluctuators, and accounting for sub-bath size improves the quality of the fit.

description: The CP-violating interaction of the nuclear magnetic quadrupole moment (MQM) of the $^{175}$Lu nucleus with electrons in the molecular cation LuOH$^+$ is studied. The resulting effect is expressed in terms of CP-odd parameters, such as quantum chromodynamics angle $\barθ$, quark electric dipole moment (EDM) and chromo-EDM. For this we have performed a calculation of the nuclear MQM as well as the molecular constant that characterises the interaction of this MQM of $^{175}$Lu with electrons. Additionally, we predict the hyperfine structure constants for the ground electronic state of LuOH$^+$. We conclude that LuOH$^+$ is a promising system to measure the nuclear MQM.

description: This article analyzes the interests and influence of the United States, Russia and China on the development of Central Asia, as well as their prospects in the region. Various stages of manifestation of the influence of these centers of power are analyzed. The authors argue that the countries of Central Asia in the post-Soviet period perceived the forces in the USA-Russia-China triangle differently, and this was one of the important conditions for the formation of their multi-vector foreign policy. In this regard, the article notes that the balance of interests of Russia, the United States and China in Central Asia ensures the development and independent foreign policy of the countries of the region

description: We examine the closedness of sets of realized neural networks of a fixed architecture in Sobolev spaces. For an exactly $m$-times differentiable activation function $ρ$, we construct a sequence of neural networks $(Φ_n)_{n \in \mathbb{N}}$ whose realizations converge in order-$(m-1)$ Sobolev norm to a function that cannot be realized exactly by a neural network. Thus, sets of realized neural networks are not closed in order-$(m-1)$ Sobolev spaces $W^{m-1,p}$ for $p \in [1,\infty]$. We further show that these sets are not closed in $W^{m,p}$ under slightly stronger conditions on the $m$-th derivative of $ρ$. For a real analytic activation function, we show that sets of realized neural networks are not closed in $W^{k,p}$ for any $k \in \mathbb{N}$. The nonclosedness allows for approximation of non-network target functions with unbounded parameter growth. We partially characterize the rate of parameter growth for most activation functions by showing that a specific sequence of realized neural networks can approximate the activation function's derivative with weights increasing inversely proportional to the $L^p$ approximation error. Finally, we present experimental results showing that networks are capable of closely approximating non-network target functions with increasing parameters via training.

description: The connection between the Gupta-Bleuler formulation and the Coulomb gauge formulation of QED is discussed. It is argued that the two formulations are not connected by a gauge transformation. Nor can the state space of the Coulomb gauge be identified with a subspace of the Gupta-Bleuler space. Instead a more indirect connection between the two formulations via a detour through the Wightman reconstruction theorem is proposed.

Going with the flow: can the base of jets subsume the role of compact accretion disk coronae?

description: The hard state of X-ray binaries (XRBs) is characterized by a power law spectrum in the X-ray band, and a flat/inverted radio/IR spectrum associated with occasionally imaged compact jets. It has generally been thought that the hard X-rays result from Compton upscattering of thermal accretion disk photons by a hot, coronal plasma whose properties are inferred via spectral fitting. Interestingly, these properties-especially those from certain magnetized corona models-are very similar to the derived plasma conditions at the jet footpoints. Here we explore the question of whether the `corona' and `jet base' are in fact related, starting by testing the strongest premise that they are synonymous. In such models, the radio through the soft X-rays are dominated by synchrotron emission, while the hard X-rays are dominated by inverse Compton at the jet base - with both disk and synchrotron photons acting as seed photons. The conditions at the jet base fix the conditions along the rest of the jet, thus creating a direct link between the X-ray and radio emission. We also add to this model a simple iron line and convolve the spectrum with neutral reflection. After forward-folding the predicted spectra through the detector response functions, we compare the results to simultaneous radio/X-ray data obtained from the hard states of the Galactic XRBs GX339-4 and Cygnus X-1. Results from simple Compton corona model fits are also presented for comparison. We demonstrate that the jet model fits are statistically as good as the single-component corona model X-ray fits, yet are also able to address the simultaneous radio data.

Ennek a tartás-1 és üzemeltetés-technológiai2 korszerűségi követelménynek csak a színszerű istállóban, almozott kötetlen tartás és a színszerű istállókban almozatlan kötetlen tartás tudnak eleget tenni. Közülük az alommentes változat – amellyel elsősorban a prognosztizált klímaváltozás miatt kell foglalkozni – még további vizsgálatokat is kíván. Építési, hőszigetelési, klimatizálási és üzemeltetési többletköltségeit a fajlagos hozamok növelésén és a minőségi mutatók javításán kívül a magasabb fokú gépesítéssel elérhető nagyobb munkatermelékenységgel és a telepi trágyakezelés korszerűbb – környezetvédelmi bírságot is elkerülő – megoldásaival és más racionalizálásokkal valószínűsíthetően ellensúlyozni lehet majd. Tapasztalatszerzés céljából szükségesnek látszik ezért egy ezt célzó K+F munka beindítása és egy a klímaváltozásra „felkészülő” tehenészeti telep konkrét meg-tervezése, felépítése, üzemeltetése és tartós üzemi vizsgálata. - The evaluation conducted confirmed the opinions to be found in specialist literature, according to which competitive, sustainable milk production is now only possible in comfortable, open stables, with unrestricted livestock milked in highly automated milking stalls – always assuming, of course, an up-to-date breed and a high standard of feeding. This requirement for modern maintenance and operation technologies can only be met by unrestricted maintenance in open stables with litter, and unrestricted maintenance in open stables without litter. Of these, the litterless variety – which must primarily be considered because of climate change predictions – requires further investigation. Besides increases in specific yields and improvements in quality indicators, the additional building, insulation, air conditioning and operational costs can in all probability be balanced by greater productivity achieved through higher levels of automation, more modern solutions for the handling of the estate’s fertilisation – thereby also avoiding environmental protection fines – and other rationalisations. It appears necessary for the purposes of gaining experience to initiate some targeted R&D work and to examine the specific planning, building, operation and sustainable operation of a dairy farm “preparing” for climate change.

Colorectal Cancer

description: Colorectal cancer (CRC) is a major public health concern being the third most diagnosed cancer in both men and women in the U.S. Regular screening can effectively reduce CRC incidence and mortality rates (Siegel et al., 2023). This study (N =155) examined the effectiveness of fear appeal messages in promoting CRC screening attitudes, intentions, and the potential moderating role of optimism. Based on the Extended Parallel Process Model, fear appeal and neutral control messages were designed and tested in an online experiment.
description: The study found no significant differences between fear appeal and control messages in their impact on perceived risks, efficacy beliefs, attitudes, or intentions toward CRC screening. The moderating effect of optimism was also not supported. Post-hoc analyses revealed that control messages were more effective in encouraging online information seeking about CRC screening.
description: These results suggest that fear appeals may not have enhanced participants' efficacy beliefs sufficiently, potentially leading to defensive responses rather than behavior change. The lack of moderation by optimism highlights the complex relationship between emotional appeals and health behavior change. Factors such as participants' readiness to change, potential message fatigue, and the need for more tailored communication strategies may have influenced the outcomes. The study's limitations include its single-exposure online design, reliance on self-reported measures, and demographically homogeneous sample. Future research should explore more diverse populations, utilize ecological momentary assessments, and investigate how messages can be tailored to different stages of behavior change readiness. Practical implications for health communicators in developing more effective CRC screening promotion strategies are discussed.

description: In this communication, we analyze the case of 3+1 dimensional scalar field cosmologies in the presence, as well as in the absence of spatial curvature, in isotropic, as well as in anisotropic settings. Our results extend those of Hawkins and Lidsey [Phys. Rev. D {\bf 66}, 023523 (2002)], by including the non-flat case. The Ermakov-Pinney methodology is developed in a general form, allowing through the converse results presented herein to use it as a tool for constructing new solutions to the original equations. As an example of this type a special blowup solution recently obtained in Christodoulakis {\it et al.} [gr-qc/0302120] is retrieved. Additional solutions of the 3+1 dimensional gravity coupled with the scalar field are also obtained. To illustrate the generality of the approach, we extend it to the anisotropic case of Bianchi types I and V and present some related open problems.

description: I reconsider Hawking's analysis of the effects of gravitational collapse on quantum fields, taking into account interactions between the fields. The ultra-high energy vacuum fluctuations, which had been considered to be an awkward peripheral feature of the analysis, are shown to play a key role. By interactions, they can scatter particles to, or create pairs of particle at, ultra-high energies. The energies rapidly become so great that quantum gravity must play a dominant role. Thus the vicinities of black holes are essentially quantum-gravitational regimes.

description: We consider magnetic Schroedinger operators on quantum graphs with identical edges. The spectral problem for the quantum graph is reduced to the discrete magnetic Laplacian on the underlying combinatorial graph and a certain Hill operator. In particular, it is shown that the spectrum on the quantum graph is the preimage of the combinatorial spectrum under a certain entire function. Using this correspondence we show that that the number of gaps in the spectrum of the Schroedinger operators admits an estimate from below in terms of the Hill operator independently of the graph structure.

description: Substituting petroleum diesel with biodiesel could decrease air emissions, reduce reliance on foreign oil, and help expand markets for U.S. farmers. Soybean producers can potentially capture this value-added by forward integrating the processing of soybeans into biodiesel via a New Generation Cooperative (NGC). Using probit analysis, this study examines factors influencing soybean producers’ willingness to participate in an NGC to produce biodiesel. Tobit analysis is used to examine the factors influencing the number of shares the soybean producer would be willing to purchase. Survey results indicate that over 70% of the soybean producers in the study group are interested in investing in an NGC to produce biodiesel. Among those producers willing to participate, the average number of shares they would purchase was just under 3,460.

$T'$ Models with High Quality Flaxions

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The "gauged'' Peccei-Quinn (PQ) mechanism of Fukuda, Ibe, Suzuki and Yanagida is implemented in the flavorful axion model of Carone and Merchand. This model of flavor is similar to other successful ones based on the double tetrahedral group, but the flavor symmetry includes a global U(1) factor that leads to the presence of a flavorful axion. Here we gauge that U(1) symmetry and introduce a heavy sector that includes (1) the fermions necessary to cancel anomalies and (2) a second scalar flavon field that spontaneously breaks the U(1) symmetry. The full theory has an accidental U(1)$\times$U(1)$'$ global symmetry, anomalous with respect to QCD; U(1)$_\text{PQ}$ emerges as a linear combination. The gauged flavor symmetry restricts the possible PQ symmetry-breaking higher-dimension operators so that sufficient axion quality is preserved. We provide a model of the quark sector, as a proof of principle, and then a model which incorporates the standard model charged leptons as well. In both cases, the charge assignments that lead to acceptable axion quality also lead to a multiplicity of some of the heavy sector states; we check that the Landau pole for hypercharge remains above the cut off of the effective theory. We consider relevant phenomenological constraints on these models including those on the predicted axion couplings.

Sources of oscillation frequency increase with rising solar activity

description: We analyze and interpret SOHO/MDI data on oscillation frequency changes between 1996 and 2004 focusing on differences between activity minimum and maximum of solar cycle 23. We study only the behavior of the centroid frequencies, which reflect changes averaged over spherical surfaces. Both the f-mode and p-mode frequencies are correlated with general measures of the sun's magnetic activity. However, the physics behind each of the two correlations is quite different. We show that for the f-modes the dominant cause of the frequency increase is the dynamical effect of the rising magnetic field. The relevant rise must occur in subphotospheric layers reaching to some 0.5 - 0.7 kG at a depth of about 5 Mm. However, the implied constraints also require the field change in the atmosphere to be so small that it has only a tiny dynamical effect on p-mode frequencies. For p-modes, the most plausible explanation of the frequency increase is a less than 2 percent decrease in the radial component of the turbulent velocity in the outer layers. Lower velocity implies a lower efficiency of the convective transport, hence lower temperature, which also contributes to the p-mode frequency increase.

The structure of hadron-quark vertex function Gamma is generalized to include various Dirac covariants (other than i gamma dot epsilon) from their complete set. They are incorporated in accordance with a naive power counting rule order by order in powers of the inverse of the meson mass. The decay constants for rho omega and phi mesons are calculated with the incorporation of leading order covariants.

description: Setting out from an analysis of the notion of the call in the works of Lévinas and his adherents, my task will be to show how that which is presented as description of a phenomenon is in fact the deconstruction of the text of tradition. In order to accomplish this, it will be apposite first to carry out an overview of the uses of the notion of the call in order to flesh out its recurring constants; subsequently, it will become possible to demonstrate the ways in which description is entirely dependent on a prerequisite act of deconstruction. That phenomenological description should thus be dependent on deconstruction explains why, in all theses texts, the notion of the call is a description of trauma which cannot account for all the dimensions of the call—such as the artistic dimension of the call exemplified by Alberti and analysed here through the example of Carvaggio's The Calling of Saint Matthew.

description: The trends of chemical abundances and abundance ratios observed in stars of different ages, kinematics, and metallicities bear the imprints of several physical processes that concur to shape the host galaxy properties. By inspecting these trends, we get precious information on stellar nucleosynthesis, the stellar mass spectrum, the timescale of structure formation, the efficiency of star formation, as well as any inward or outward flows of gas. In this paper, we analyse recent determinations of carbon-to-iron and carbon-to-oxygen abundance ratios in different environments (the Milky Way and elliptical galaxies) using our latest chemical evolution models that implement up-to-date stellar yields and rely on the tight constraints provided by asteroseismic stellar ages (whenever available). A scenario where most carbon is produced by rotating massive stars, with yields largely dependent on the metallicity of the parent proto-star clouds, allows us to fit simultaneously the high-quality data available for the local Galactic components (thick and thin discs) and for microlensed dwarf stars in the Galactic bulge, as well as the abundance ratios inferred for massive elliptical galaxies. Yet, more efforts are needed from both observers and theoreticians in order to base these conclusions on firmer grounds.

description: In this note we present explicit canonical forms for all the elements in the two-qubit CNOT-Dihedral group, with minimal numbers of controlled-S (CS) and controlled-X (CX) gates, using the generating set of quantum gates [X, T, CX, CS]. We provide an algorithm to successively construct the n-qubit CNOT-Dihedral group, asserting an optimal number of controlled-X (CX) gates. These results are needed to estimate gate errors via non-Clifford randomized benchmarking and may have further applications to circuit optimization over fault-tolerant gate sets.

description: The (Fefferman-Graham) ambient obstruction tensor is a conformally invariant symmetric trace-free 2-tensor on even-dimensional Riemannian and pseudo-Riemannian manifolds. The conformal deformation complex is a differential complex related to infinitesimal deformations of conformal structure. We construct a conformally invariant differential operator on algebraic Weyl tensors that gives special curved analogues of certain operators related to the deformation complex and that, upon application to the Weyl curvature, yields the obstruction tensor. This new definition of the obstruction tensor leads to simple direct proofs that the obstruction tensor is divergence free and vanishes for a class of metrics which (strictly) includes the class of conformally Einstein metrics. Our main constructions are based on the ambient metric of Fefferman-Graham and its relation to the conformal tractor connection. We prove that the obstruction tensor is an obstruction to the formal problem of obtaining a Ricci-flat ambient metric and that it may equivalently be viewed as the obstruction to finding an ambient metric with curvature harmonic for a certain (ambient) form Laplacian. This leads to a new ambient formula for the obstruction in terms of a power of this form Laplacian acting on the ambient curvature. This result leads us to construct Laplacian type operators that generalise the conformal Laplacians of Graham-Jenne-Mason-Sparling. As background to these issues, we give an explicit construction of the deformation complex in dimensions n>3, construct two related (detour) complexes, and establish essential properties of the operators in these.

Life and landscape : creating spaces for birth
Creators: name: Johnstone, Shana
Publisher: name: University of British Columbia
Year: 2009

description: The need for birth centres in British Columbia is the impetus behind this project that supplies a model for birth centre design. The project explores the design of a birth centre from an historical, programmatic and experiential perspective. The birth centre is located contextually as a concept resulting from the interface between the rising medical profession and the long history and current struggles of midwifery practice in the West. Issues of women's autonomy, concerning both midwives and women giving birth, are highlighted by this historical research, and the experience of birth is at the forefront of the design agenda. British Columbia precedents for maternity care are examined for program, spatial requirements and character. The programmatic requirements of a birth centre are developed to support a midwifery model of care, and are expanded to include an outdoor program and a spiritual program that connects the experience of birth to the natural landscape. A set of criteria for site selection is provided to account for the selection of the project site, and to be used in the selection for birth centre sites throughout British Columbia. Site analysis describes the opportunities and constraints of the chosen site, and details the physical elements of the site that the design responds to. The site design illustrates the types of spaces necessary for the birth centre program, their organization, and their experiential character. Design components include a main facility, separate birthing suites, a gathering area, ceremonial areas, and a circulation network.

description: Data from the U.S. Department of Agriculture’s 1994-96 and 1998 Continuing Survey of Food Intakes by Individuals (CSFII) are used to describe pork consumption patterns as well as to estimate a censored demand system for pork cuts. The descriptive analysis fills the void about basic information on who consumes pork, how much, and where. A censored system of four pork cuts is estimated for adults, using a maximum-likelihood procedure. The estimated system is used to predict consumption of pork products by adults through the year 2020.

description: The several ways of access to artworks and their various ways of presentation play a main part in the current situation of art. It is time for philosophical thought to take them into account. These remarks aim to clarify this situation, and to draw some of it consequences, from a philosophical view intended to incorporate into our concept of art its different ways of activation. The art factory has more than one trick up one's sleeve, and criticism can be also caught out. We need a change in artworks ontology.

description: Metal and magnetic overlayers alter the surface of the topological insulator (TI) bismuth selenide (Bi$_2$Se$_3$) through proximity effects but also by changing the composition and chemical structure of the Bi$_2$Se$_3$ sub-surface. The interface between Bi$_2$Se$_3$ and Mn metal or manganese selenide was explored using x-ray photoelectron spectroscopy (XPS) revealing chemical and electronic changes at the interface. Depositing Mn metal on Bi$_2$Se$_3$ without an external source of Se shows unexpected bonding within the Mn layer due to Mn-Se bonding as Se diffuses out of the Bi$_2$Se$_3$ layer into the growing Mn film. The Se out-diffusion is further evidenced by changes in Bi core levels within the Bi$_2$Se$_3$ layers indicating primarily Bi-Bi bonding over Bi-Se bonding. No out-diffusion of Se occurred when excess Se is supplied with Mn, indicating the importance of supplying enough chalcogen atoms with deposited metals. However, Bi$_2$Se$_3$ core level photoelectrons exhibited a rigid chemical shift toward higher binding energy after depositing a monolayer of MnSe$_{2-x}$, indicating a dipole within the overlayer. Stoichiometry calculations indicated that the monolayer forms MnSe preferentially over the transition metal dichalcogenide (TMD) phase MnSe$_2$, providing a consistent picture of the dipole formation in which a plane of Se anions sits above Mn cations. This study shows that chemical diffusion and dipole formation are important for Mn-Bi$_2$Se$_3$ and MnSe$_{2-x}$-Bi$_2$Se$_3$ and should be considered carefully for TMD/TI interfaces more generally.

description: We review the new possibilities offered by the reaction dynamics of asymmetric heavy ion collisions, using stable and unstable beams. We show that it represents a rather unique tool to probe regions of highly Asymmetric Nuclear Matter ($ANM$) in compressed as well as dilute phases, and to test the in-medium isovector interaction for high momentum nucleons. The focus is on a detailed study of the symmetry term of the nuclear Equation of State ($EOS$) in regions far away from saturation conditions but always under laboratory controlled conditions. Thermodynamic properties of $ANM$ are surveyed starting from nonrelativistic and relativistic effective interactions. In the relativistic case the role of the isovector scalar $δ$-meson is stressed. The qualitative new features of the liquid-gas phase transition, "diffusive" instability and isospin distillation, are discussed. The results of ab-initio simulations of n-rich, n-poor, heavy ion collisions, using stochastic isospin dependent transport equations, are analysed as a function of beam energy and centrality. The isospin dynamics plays an important role in all steps of the reaction, from prompt nucleon emissions to the final fragments. The isospin diffusion is also of large interest, due to the interplay of asymmetry and density gradients. In relativistic collisions, the possibility of a direct study of the covariant structure of the effective nucleon interaction is shown. Results are discussed for particle production, collective flows and iso-transparency. Perspectives of further developments of the field, in theory as well as in experiment, are presented.

Getting to the heart of psychopathy and moral responsibility

Publisher: name: University of British Columbia

description: Psychopaths. Who are they? What are they? How do they differ from the rest of us "normals?" And, why do they differ from the rest of us "normals?" For most of us, the word "psychopath" conjures up images of notorious serial killers, like Charles Manson, Ted Bundy, Jeffrey Dahmer, or Hannibal Lecter. However, psychopaths are not necessarily just serial killers. There crimes are often, and typically, petty offences, social misdeeds, or "crimes of the heart." They can be found in every community and in every profession. For the most part, they are identified in the psychological literature in terms of having an emotional deficit. Their characteristic feature, along these lines, is a lack of empathy, which is an imperative source of moral motivation. As such, philosophers generally discuss psychopaths in the context of notions associated with freedom and moral responsibility. The main question that is typically examined by philosophers, in this context, is whether or not psychopaths can legitimately be held morally responsible for their actions in light of their inherent lack of empathy. However, philosophers rarely make close contact with the psychological literature to examine the nature of the psychopath in developing their views. In this project, I briefly examine and explicate the psychological literature that illuminates the nature and development of the psychopath - from both the nature and nurture perspectives. By doing so, I am able to lay a foundation upon which a critical comparison can be made - between the nature of the psychopath and the nature of the non-psychopath - in working towards determining the essential ingredients that constitute moral agency, subsequent attributions of moral responsibility, and, ultimately, whether or not psychopaths can legitimately be held morally responsible for their actions.
