description: Context. GJ 581, an M3 dwarf, hosts a rich system of exo-planets, some of which are potentially within or at the edge of the Habitable Zone. Nevertheless the system habitability might be reduced by large and sterilizing high energy emission flares, if these are frequent. Aims. The GJ 581 radiation environment was studied with simultaneous X-ray and UV observations, performed with the XRT and UVOT instruments, respectively, on board of the SWIFT satellite. Methods. X-ray and UV data were analysed with the distributed standard tools. Results. GJ 581 was detected for the first time in the 0.2-10 keV range, with an intensity of (8+-2)x10^{-4} cts/s and a signal-to-noise ratio of 3.6. If black-body or APEC spectra are assumed then the source X-ray flux is found to be between 1.8 and 3.3x10^{-14}erg cm^{-2}s^{-1} and log10(L_{X}) between 25.914 and 26.176. Despite hints of X-ray variability, better statistics will be needed to establish robust evidence for that. The UV measurements, obtained during 13 pointings, are also reported. A combination of these Swift X-ray and Hubble Space Telescope UV measurements (with Lyman-alpha) indicate a low X-ray to UV luminosity ratio of ~4%. Conclusions. Simultaneous X-ray and UV observations of GJ 581 are reported. These constitute an experimental view of the system radiation environment, which will be a useful input for the habitability studies of the GJ 581 planetary system.

description: We present a study of the magnetic and crystallographic structure of TbMnO$_3$ in the presence of crossed electric and magnetic fields using circularly polarised X-ray non-resonant scattering. A comprehensive account is presented of the scattering theory and data analysis methods used in our earlier studies, and in addition we present new high magnetic field data and its analysis. We discuss in detail how polarisation analysis was used to reveal structural information, including the arrangement of Tb moments which we proposed for $H = 0$ T, and how the diffraction data for $H H_C$ as for $H < H_C$. Finally some observations regarding the kinetics and the conservation of domain population at the transition are described.

A Multidimensional Social Inquiry into the Loneliness Problem: Urbanization, Technological Mediation, and Neoliberal Individualism
Creators: Milbrandt, Tara

Publisher: name: University of Alberta Library
Year: 2023

Loneliness is not one thing. There is a need for a broad and multidimensional social approach to loneliness—even broader than a public health approach—that could take up the problem of loneliness as a complex phenomenon. Ideally, such an approach would consider how we might create conditions for meaningful forms of social connectivity that nourish and sustain people across the social landscape and along the life course, both in the ordinary circumstances of everyday life and in the face of extraordinary circumstances and large-scale collective disturbances, such as the COVID-19 pandemic. As we stress in our review of materials, loneliness is best approached through a culturally sensitive and intersectional approach, one attentive to marginalization and oriented to meaningful participation and inclusion across the diverse social world. It is also important to be attentive to both the built environment and to the environment of ideas, values, and judgments in order to recognize and address loneliness as a social issue that demands social solutions. In this report, we have identified a series of research priorities and policy recommendations, guided by general principles and targeted in specific ways in relevant contexts, that can support a multidimensional approach to understanding and addressing loneliness.
Gravitational waves in scalar-tensor theory to one-and-a-half post-Newtonian order

description: We compute the gravitational waves generated by compact binary systems in a class of massless scalar-tensor (ST) theories to the 1.5 post-Newtonian (1.5PN) order beyond the standard quadrupole radiation in general relativity (GR). Using and adapting to ST theories the multipolar-post-Minkowskian and post-Newtonian formalisms originally defined in GR, we obtain the tail and non-linear memory terms associated with the dipole radiation in ST theory. The multipole moments and GW flux of compact binaries are derived for general orbits including the new 1.5PN contribution, and comparison is made with previous results in the literature. In the case of quasi-circular orbits, we present ready-to-use templates for the data analysis of detectors, and for the first time the scalar GW modes for comparisons with numerical relativity results.

description: The joint probability distribution function (PDF) of the density within multiple concentric spherical cells is considered. It is shown how its cumulant generating function can be obtained at tree order in perturbation theory as the Legendre transform of a function directly built in terms of the initial moments. In the context of the upcoming generation of large-scale structure surveys, it is conjectured that this result correctly models such a function for finite values of the variance. Detailed consequences of this assumption are explored. In particular the corresponding one-cell density probability distribution at finite variance is computed for realistic power spectra, taking into account its scale variation. It is found to be in agreement with $Λ$-CDM simulations at the few percent level for a wide range of density values and parameters. Related explicit analytic expansions at the low and high density tails are given. The conditional (at fixed density) and marginal probability of the slope -- the density difference between adjacent cells -- and its fluctuations is also computed from the two-cells joint PDF; it also compares very well to simulations, in particular in under-dense regions, with a significant reduced cosmic scatter compared to over-dense regions. It is emphasized that this could prove useful when studying the statistical properties of voids as it can serve as a statistical indicator to test gravity models and/or probe key cosmological parameters.

description: Dark matter made from non-thermally produced bosons can have very low, possibly sub-eV masses. Axions and hidden photons are prominent examples of such "dark" very weakly interacting light (slim) particles (WISPs). A suitable mechanism for their non-thermal production is the misalignment mechanism. Their dominant interaction with Standard Model (SM) particles is via photons. In this note we want to go beyond these standard examples and discuss a wide range of scalar and pseudo-scalar bosons interacting with SM matter fermions via derivative interactions. Suitably light candidates arise naturally as pseudo-Nambu-Goldstone bosons. In particular we are interested in examples, inspired by familons, whose interactions have a non-trivial flavor structure.

description: Subfamily Mystromyinae Vorontsov, 1966. Zool. Zh., 45:437. COMMENTS: Phylogenetic allocation of Mystromys so puzzled Ellerman (1941:445) that he wrote "I am entirely at a loss to suggest the relationships of this genus, which seems not only isolated from the Palaearctic and Neotropical genera, but to have no marked generic characters... " Based on study of external, skeletal, dentition, gastrointestinal, genital and other anatomical characteristics of Mystromys albicaudatus, Vorontsov (1966) concluded the species was not closely related to Palaearctic hamsters and placed Mystromys in the monotypic tribe Mystromyini. Carleton and Musser (1984:313) remarked that Mystromys is possibly a survivor of an ancient phyletic line, pointing out that Lavocat (1973, 1978) "raised such a novel possibility for Mystromys by noting its probable derivation from afrocricetodontine rodents and by recognizing the subfamily Mystromyinae in the Nesomyidae, a family composed of archaic African cricetids that he derived from the afrocricetodontines, the African counterpart to European and Asian cricetodontines." Pocock (1987) and Skinner and Smithers (1990) retained Mystromys in the Cricetinae of family Cricetidae.

description: We consider a linearly elastic body consisting of two equal symmetrically arranged layers (or half-planes) connected by a structured interface as a prospective crack path. The interface is comprised by periodic discrete system of bonds. In the initial state with no external forces, the bonds are assumed to be stressed in such a way that tensile and compressive forces of the same value alternate. In the general considerations, the layers are assumed to be of a general, unspecified {\em periodic} structure, where such self-equilibrated residual stresses can also exist. A two-line chain and an anisotropic lattice are examined as illustrative examples. We consider the states of the body-with-a-crack under the residual stresses and under a combined action of the remote forces and residual stresses. Analytical solutions to the considered problems are presented. The solutions are based on a selective discrete transform introduced. In particular, it is found that a formula for local-to-global energy release ratio, written in terms of the Wiener-Hopf equation kernel, is very general. We show that the residual stresses can manifest themselves in a number of phenomena such as the crack bridging, `porous' in front of the crack and crack growth irregularities. We also demonstrate analytically and graphically that the residual stresses can result in increase as well as in decrease of the crack resistance depending on the internal energy level. The quasi-static considerations suggest different scenarios of the crack growth depending on the internal energy level.

description: The predominant centralized paradigm in educational data management currently suffers from several critical issues such as vulnerability to malicious tampering, a high prevalence of diploma counterfeiting, and the onerous cost of certificate authentication. Decentralized blockchain technology, with its cutting-edge capabilities, presents a viable solution to these pervasive problems. In this paper, we illuminate the inherent limitations of existing centralized systems and introduce EduChain, a novel heterogeneous blockchain-based system for managing educational data. EduChain uniquely harnesses the strengths of both private and consortium blockchains, offering an unprecedented level of security and efficiency. In addition, we propose a robust mechanism for performing database consistency checks and error tracing. This is achieved through the implementation of a secondary consensus, employing the pt-table-checksum tool. This approach effectively addresses the prevalent issue of database mismatches. Our system demonstrates superior performance in key areas such as information verification, error traceback, and data security, thereby significantly improving the integrity and trustworthiness of educational data management. Through EduChain, we offer a powerful solution for future advancements in secure and efficient educational data management.

description: We show that the isotropic conductivity in the normal state of rare-earth tritelluride RTe_3 compounds is broken by the occurrence of the unidirectional charge density wave (CDW) in the (a,c) plane below the Peierls transition temperature. In contrast with quasi-one-dimensional systems, the resistivity anomaly associated with the CDW transition is strong in the direction perpendicular to the CDW wave vector Q (a-axis) and very weak in the CDW wave vector Q direction (c-axis). We qualitatively explain this result by calculating the electrical conductivity for the electron dispersion with momentum-dependent CDW gap as determined by angle-resolved photoemission spectroscopy (ARPES).

description: In this report we examine a range of employee information and consultation mechanisms in 15 organisations in the Republic of Ireland. The research was conducted specifically in relation to the European Employee Information and Consultation Directive. While we note that many managerial respondents identified a positive link between employee consultation and organisational performance, the efficacy and interpretations of how these mechanisms operate in practice differed quite substantially according to employees. The evidence suggests that regulations contained in the European Directive provide the opportunities for more effective employee voice systems and the platform to extend representational rights at workplace level.

description: It has long been suggested that CH2CN- might be a carrier of one of the many poorly characterized diffuse interstellar bands. In this paper, our aim is to study various forms of CH2CN in the interstellar medium. Aim of this paper is to predict spectroscopic characteristics of various forms of CH2CN and its deuterated derivatives. Moreover, we would like to model the interstellar chemistry for making predictions for the column densities of such species around dark cloud conditions. A detailed quantum chemical simulations to present the spectral properties of various forms of the CH2CN. MP2 theory along with the aug-CCPVTZ basis set is used to obtain different spectroscopic constants of CH2CN-, CHDCN- and CD2CN- in the gas phase which are essential to predict rotational spectra of these species. We performed quantum chemical calculation to find out energetically the most stable spin states for these species. We have computed IR and electronic absorption spectra for different forms of CH2CN. Moreover, we have also implemented a large gas-grain chemical network to predict the column densities of various forms of the cyanomethyl radical and its related species. In order to mimic physical conditions around a dense cloud region, the variation of the visual extinction parameters are considered with respect to the hydrogen number density of the simulated cloud. Our quantum chemical calculation reveals that the singlet spin state is the most stable form of cyanomethyl anion and its deuterated forms. For the confirmation of the detection of the cyanomethyl anion and its two deuterated forms, namely, CHDCN- and CD2CN-, we present the rotational spectral information of these species in the Appendix. Our chemical model predicts that the deuterated forms of cyanomethyl radicals (specially the anions) are also reasonably abundant around the dense region of the molecular cloud.

description: Many methods have been developed for measuring the mass of invisible particles that only use kinematic information available at hadron colliders. Because a particle is identified by its mass, these methods are critical when distinguishing between dark matter and fake dark matter, where a neutrino or other massless states can mimic a dark-matter signal. However, the uncertainty associated with measuring the mass of an invisible particle could be so large that it is indistinguishable from a neutrino. Monte Carlo is used to estimate lower bounds on how heavy an invisible particle must be in order for it to be distinguishable from a massless one at 95% CL, which we estimate to be O(10 GeV). This result, to a good approximation, is independent of the way the massive final-state particle is produced. If there is a light dark-matter particle with mass O(10 GeV), its presence will be difficult to unambiguously identify at the LHC, using kinematic information alone.

description: Cyberspace is a fragile construct threatened by malicious cyber operations of different actors, with vulnerabilities in IT hardware and software forming the basis for such activities, thus also posing a threat to global IT security. Advancements in the field of artificial intelligence accelerate this development, either with artificial intelligence enabled cyber weapons, automated cyber defense measures, or artificial intelligence-based threat and vulnerability detection. Especially state actors, with their long-term strategic security interests, often stockpile such knowledge of vulnerabilities and exploits to enable their military or intelligence service cyberspace operations. While treaties and regulations to limit these developments and to enhance global IT security by disclosing vulnerabilities are currently being discussed on the international level, these efforts are hindered by state concerns about the disclosure of unique knowledge and about giving up tactical advantages. This leads to a situation where multiple states are likely to stockpile at least some identical exploits, with technical measures to enable a depletion process for these stockpiles that preserve state secrecy interests and consider the special constraints of interacting states as well as the requirements within such environments being non-existent. This paper proposes such a privacy-preserving approach that allows multiple state parties to privately compare their stock of vulnerabilities and exploits to check for items that occur in multiple stockpiles without revealing them so that their disclosure can be considered. We call our system ExTRUST and show that it is scalable and can withstand several attack scenarios. Beyond the intergovernmental setting, ExTRUST can also be used for other zero-trust use cases, such as bug-bounty programs.

On the interplay between electrical conductivity and Seebeck coefficient in ultra-narrow silicon nanowires

description: We analyze the effect of low dimensionality on the electrical conductivity (σ) and Seebeck coefficient (S) in ultra-narrow Si nanowires (NWs) by employing atomistic considerations for the electronic structures and linearized Boltzmann transport theory. We show that changes in the geometrical features of the NWs such as diameter and orientation, mostly affect σ and S in two ways: i) the distance of the band edges from the Fermi level (ηF) changes, and ii) quantum confinement in some cases strongly affect the effective mass of the subbands, which influences the conductivity of the NWs and ηF. Changes in eta_F cause exponential changes in σ, but linear changes in S. S seems to be only weakly dependent on the curvature of the bands, the strength of the scattering mechanisms, and the shape of the DOS(E) function, contrary to current view. Our results indicate that low dimensionality has a stronger influence on σ than on S due to the stronger sensitivity of σ on ηF. We identify cases where bandstructure engineering through confinement can improve σ without significantly affecting S, which can result in power factor improvements.

description: We present a derivation of an exact high temperature expansion for a one-loop thermodynamic potential $Ω(\tildeμ)$ with complex chemical potential $\tildeμ$. The result is given in terms of a single sum the coefficients of which are analytical functions of $\tildeμ$ consisting of polynomials and polygamma functions, decoupled from the physical expansion parameter $βm$. The analytic structure of the coefficients permits us to explicitly calculate the thermodynamic potential for the imaginary chemical potential and analytically continue the domain to the complex $\tildeμ$ plane. Furthermore, our representation of $Ω(\tildeμ)$ is particularly well suited for the Landau--Ginzburg-type of phase transition analysis. This fact, along with the possibility of interpreting the imaginary chemical potential as an effective generalized-statistics phase, allows us to investigate the singular origin of the $m^3$ term appearing only in the bosonic thermodynamic potential.

description: We present a theoretical study of momentum-resolved tunneling between parallel two-dimensional conductors whose charge carriers have a (pseudo-)spin-1/2 degree of freedom that is strongly coupled to their linear orbital momentum. Specific examples are single and bilayer graphene as well as single-layer molybdenum disulphide. Resonant behavior of the differential tunneling conductance exhibited as a function of an in-plane magnetic field and bias voltage is found to be strongly affected by the (pseudo-)spin structure of the tunneling matrix. We discuss ramifications for the direct measurement of electronic properties such as Fermi surfaces and the dispersion curves. Furthermore, using a graphene double-layer structure as an example, we show how magneto-tunneling transport can be used to measure the pseudo-spin structure of tunnel matrix elements, thus enabling electronic characterization of the barrier material.

Low-Cost GNSS Simulators with Wireless Clock Synchronization for Indoor Positioning

description: In regions where global navigation satellite systems (GNSS) signals are unavailable, such as underground areas and tunnels, GNSS simulators can be deployed for transmitting simulated GNSS signals. Then, a GNSS receiver in the simulator coverage outputs the position based on the received GNSS signals (e.g., Global Positioning System (GPS) L1 signals in this study) transmitted by the corresponding simulator. This approach provides periodic position updates to GNSS users while deploying a small number of simulators without modifying the hardware and software of user receivers. However, the simulator clock should be synchronized to the GNSS satellite clock to generate almost identical signals to the live-sky GNSS signals, which is necessary for seamless indoor and outdoor positioning handover. The conventional clock synchronization method based on the wired connection between each simulator and an outdoor GNSS antenna causes practical difficulty and increases the cost of deploying the simulators. This study proposes a wireless clock synchronization method based on a private time server and time delay calibration. Additionally, we derived the constraints for determining the optimal simulator coverage and separation between adjacent simulators. The positioning performance of the proposed GPS simulator-based indoor positioning system was demonstrated in the underground testbed for a driving vehicle with a GPS receiver and a pedestrian with a smartphone. The average position errors were 3.7 m for the vehicle and 9.6 m for the pedestrian during the field tests with successful indoor and outdoor positioning handovers. Since those errors are within the coverage of each deployed simulator, it is confirmed that the proposed system with wireless clock synchronization can effectively provide periodic position updates to users where live-sky GNSS signals are unavailable.

description: The cosmic censorship conjecture posits that singularities forming to the future of a regular Cauchy surface are hidden by an event horizon. Consequently any topological structures will ultimately collapse within the horizon of a set of black holes and so no observer can actively probe them classically. We consider here a quantum analog of this problem, in which we compare the transition rates of an Unruh-DeWitt detector placed outside the horizon of an eternal BTZ black hole and its associated geon counterpart. We find the transition rates differ, with the latter being time-dependent, implying that we are indeed able to probe the structure of the singularity from outside the Killing horizon.

description: A classical view of neural coding relies on temporal firing synchrony among functional groups of neurons; however the underlying mechanism remains an enigma. Here we experimentally demonstrate a mechanism where time-lags among neuronal spiking leap from several tens of milliseconds to nearly zero-lag synchrony. It also allows sudden leaps out of synchrony, hence forming short epochs of synchrony. Our results are based on an experimental procedure where conditioned stimulations were enforced on circuits of neurons embedded within a large-scale network of cortical cells in vitro and are corroborated by simulations of neuronal populations. The underlying biological mechanisms are the unavoidable increase of the neuronal response latency to ongoing stimulations and temporal or spatial summation required to generate evoked spikes. These sudden leaps in and out of synchrony may be accompanied by multiplications of the neuronal firing frequency, hence offering reliable information-bearing indicators which may bridge between the two principal neuronal coding paradigms.
