description: Coronavirus disease-19 (COVID-19), caused by a β-coronavirus and its genomic variants, is associated with substantial morbidities and mortalities globally. The COVID-19 virus and its genomic variants enter host cells upon binding to the angiotensin converting enzyme 2 receptors that are expressed in a variety of tissues, but predominantly in the lungs, heart, and blood vessels. Patients afflicted with COVID-19 may be asymptomatic or present with critical symptoms possibly due to diverse lifestyles, immune responses, aging, and underlying medical conditions. Geriatric populations, especially men in comparison to women, with immunocompromised conditions, are most vulnerable to severe COVID-19 associated infections, complications, and mortalities. Notably, whereas immunomodulation, involving nutritional consumption, is essential to protecting an individual from COVID-19, immunosuppression is detrimental to a person with this aggressive disease. As such, immune health is inversely correlated to COVID-19 severity and resulting consequences. Advances in genomic and proteomic technologies have helped us to understand the molecular events underlying symptomatology, transmission and, pathogenesis of COVID-19 and its genomic variants. Accordingly, there has been development of a variety of therapeutic interventions, ranging from mask wearing to vaccination to medication. This review summarizes the current understanding of molecular pathogenesis of COVID-19, effects of comorbidities on COVID-19, and prospective therapeutic strategies for the prevention and treatment of this contagious disease.

description: Актуальность вопроса определения физической активности обусловлена необходимостью разграничения и унификации понятий «физическая активность» и «двигательная активность» в российской педагогической науке с позиций кинезиологии. Проведен анализ публикаций в гуманитарных и естественных научных дисциплинах о сущности физической активности и ее понимании педагогической наукой, биологией и медициной на основе комплексного междисциплинарного подхода. Показано, что кинезиология выступает объединительной платформой, на которой воз-можно успешное сотрудничество специалистов, изучающих человека в движении, а унификация и закрепление в научном обиходе понятия «физическая активность» позволит интегрировать отечественную кинезиологию в международное научное сообщество.
description: The relevance of the issue of defining physical activity is due to the need of distinguishing and unifying the concepts of "physical activity" and "motor activity" in the pedagogical science of Russia through the lens of kinesiology. An analysis of publications in the fields of human and natural disciplines regarding the essence of physical activity and its understanding in pedagogy, biology and medicine is performed based on the comprehensive interdisciplinary approach. It is shown that kinesiology acts as a unifying platform for successful cooperation of professionals studying a human in motion. Unification and formalization of the concept of "physical activity" in scientific use will allow integrating domestic human kinesiology into the international academic community.

description: As a fundamental parameter in magnetism, the phenomenological Gilbert damping constant a determines the performance of many spintronic devices. For most magnetic materials, a is treated as an isotropic parameter entering the Landau-Lifshitz-Gilbert equation. However, could the Gilbert damping be anisotropic? Although several theoretical approaches have suggested that anisotropic a could appear in single-crystalline bulk systems, experimental evidence of its existence is scarce. Here, we report the emergence of anisotropic magnetic damping by exploring a quasi-two-dimensional single-crystalline ferromagnetic metal/semiconductor interface-that is, a Fe/GaAs(001) heterojunction. The observed anisotropic damping shows twofold C-2v symmetry, which is expected from the interplay of interfacial Rashba and Dresselhaus spin-orbit interaction, and is manifested by the anisotropic density of states at the Fe/GaAs (001) interface. This discovery of anisotropic damping will enrich the understanding of magnetization relaxation mechanisms and can provide a route towards the search for anisotropic damping at other ferromagnetic metal/semiconductor interfaces.

description: Hybrid phantoms allow for measurement-based evaluation of particle samples, reconstruction algorithms and field sequences without need of a Magnetic Particle Imaging (MPI) scanning device. Even dynamic hybrid phantoms can be generated using dynamic magnetic offset fields. Multi-dimensional Magnetic Particle Spectrometers are capable of emulating both hybrid system matrices and hybrid phantoms, which can be reconstructed into images. It is shown that a spatial resolution of few hundred micrometres can be achieved for both one- and multi-dimensional excitation using MPI technology. The spatial resolution of reconstructed images increases when including additional receive channels into the reconstruction process. For multi-dimensional imaging the sine-based Lissajous trajectory outperforms the cosine-based Lissajous trajectory in terms of spatial resolution. Both the high signal to noise ratio of a spectrometer and the versatility of hybrid phantom design will enforce innovative measurement-based research on key parameters for MPI. Int. J. Mag. Part.

Magnetic Particle Imaging Using Discrete Sampling and Image Reconstruction with Few Orthogonal Bases Obtained by Singular Value Decomposition of Selected Delta Responses

Publisher: name: International Journal on Magnetic Particle Imaging
Year: 2020

description: The conventional magnetic particle imaging reconstruction methods use observed signals and system functions, which result in an enormous amount of data and long processing time being required to reconstruct large image matrices. We propose a new image reconstruction method that uses less data and a limited number of orthogonal bases obtained via the singular value decomposition (SVD) of selected point spread functions (PSFs). By using the features of the diagonal and nondiagonal elements of a singular value matrix, image blurring and artifacts can be reduced in the reconstructed image. This is because the diagonal components commonly indicate the similarities between each orthogonal basis for the system function and an observed signal, whereas the nondiagonal components indicate the differences of both them. In this paper, we use numerical analyses to demonstrate that image reconstruction is possible by using effective orthogonal bases obtained through the SVD of a limited number of PSFs selected from a general system function. The reconstruction time is reduced to 1/12th to 1/50th of that of the conventional method. Int. J. Mag. Part. Imag. 6(1), 2020, Article ID: 2003003, DOI: 10.18416/IJMPI.2020.2003003

description: The unchecked spread of misinformation is recognized as an increasing threat to public, scientific and democratic health. Online networks are a contributing cause of this spread, with echo chambers and polarization indicative of the interplay between the search behaviours of users and reinforcement processes within the system they inhabit. Recent empirical work has focused on interventions aimed at inoculating people against misinformation, yielding success on the individual level. However, given the evolving, dynamic information context of online networks, important questions remain regarding how such inoculation interventions interact with network systems. Here we use an agent-based model of a social network populated with belief-updating users. We find that although equally rational agents may be assisted by inoculation interventions to reject misinformation, even among such agents, intervention efficacy is temporally sensitive. We find that as beliefs disseminate, users form self-reinforcing echo chambers, leading to belief consolidation-irrespective of their veracity. Interrupting this process requires 'front-loading' of inoculation interventions by targeting critical thresholds of network users before consolidation occurs. We further demonstrate the value of harnessing tipping point dynamics for herd immunity effects, and note that inoculation processes do not necessarily lead to increased rates of 'false-positive' rejections of truthful communications.

description: We study the confinement/deconfinement transition in the D0-brane matrix model (often called the BFSS matrix model) and its one-parameter deformation (the BMN matrix model) numerically by lattice Monte Carlo simulations. Our results confirm general expectations from the dual string/M-theory picture for strong coupling. In particular, we observe the confined phase in the BFSS matrix model, which is a nontrivial consequence of the M-theory picture. We suggest that these models provide us with an ideal framework to study the Schwarzschild black hole, M-theory, and furthermore, the parameter region of the phase transition between type IIA superstring theory and M-theory. A detailed study of M-theory via lattice Monte Carlo simulations of the D0-brane matrix model might be doable with much smaller computational resources than previously expected.
Unique Conservative Solutions to a Variational Wave Equation

description: Relying on the analysis of characteristics, we prove the uniqueness of conservative solutions to the variational wave equation $u_{tt}-c(u) (c(u)u_x)_x=0$. Given a solution $u(t,x)$, even if the wave speed $c(u)$ is only Hölder continuous in the $t$-$x$ plane, one can still define forward and backward characteristics in a unique way. Using a new set of independent variables $X,Y$, constant along characteristics, we prove that $t,x,u$, together with other variables, satisfy a semilinear system with smooth coefficients. From the uniqueness of the solution to this semilinear system, one obtains the uniqueness of conservative solutions to the Cauchy problem for the wave equation with general initial data $u(0,\cdot)\in H^1(\mathbb{R})$, $u_t(0,\cdot)\in L^2(\mathbb{R})$.

description: I libertini eruditi del XVII secolo, pensatori, scrittori, studiosi assai eterogenei e con esiti molto diversi tra loro, sono accumunati da due caratteristiche: una profonda irreligiosità e uno stile obliquo di scrittura. Essi riflettono su come nascono le religioni e con quali subdoli meccanismi alcuni uomini, avidi di potere, sfruttano la naturale debolezza e la credulità dei loro simili. La riflessione libertina sulla religione si presenta innanzi tutto come esame dei meccanismi di persuasione e di formazione delle credenze; meccanismi fortemente influenzati da processi passionali e dalla credulità prodotta dall’ignoranza, che costituiscono quindi il fondamento primo di ogni religione. In secondo luogo i libertini analizzano come la religione sia stata utilizzata da parte di abili «legislatori» che hanno ingannato gli uomini per fondare su solide basi nuove società e nuovi imperi. “Instrumentum regni” .

description: We determine the leading order mesonic (B0 and F0) and baryonic (m0, D and F) SU(3) chiral perturbation theory low energy constants from lattice QCD. We employ gauge ensembles with Nf=3 (i.e., mu=md=ms) nonperturbatively improved Wilson fermions at six distinct values of the lattice spacing in the range a≈(0.039–0.098) fm, which constitute a subset of the coordinated lattice simulations (CLS) gauge ensembles. The pseudoscalar meson mass Mπ ranges from around 430 MeV down to 240 MeV and the linear spatial lattice extent L from 6.4M−1π to 3.3M−1π, where LMπ≥4 for the majority of the ensembles. This allows us to perform a controlled extrapolation of all the low energy constants to the chiral, infinite volume and continuum limits. We find the SU(3) chiral condensate and F0 to be smaller than their SU(2) counterparts while the Gell-Mann–Oakes–Renner parameters B0≈B are similar. Regarding baryonic LECs, we obtain F/D=0.612⁽¹⁴⁾₍₁₂₎.

description: Escherichia coli O157 (E. coli O157) is responsible for outbreaks of high morbidity in food-borne infections. The development of sensitive, reliable, and selective detection systems is of great importance in food safety. In this work, two high fundamental frequency (HFF) piezoelectric genosensors (100 and 150 MHz) were designed and validated for the rfbE gene detection, which encodes O-antigen in E. coli O157. HFF resonators offer improved sensitivity, small sample volumes, and the possibility of integration into lab-on-a-chip devices, but their sensing capabilities have not yet been fully explored. This HFF-QCM genosensor uses the method of physisorption based on the union between the streptavidin and the biotin to immobilize the genetic bioreceptor on the surface and detect its hybridization with the target sequence. Parameters such as molecular coating, specificity, and variability were tested to enhance its performance. Although both genosensors evaluated are able to determine the target, the 100 MHz device has a higher response to the analyte than the 150 MHz platform. This is the first step in the development of an HFF-QCM genosensor that may be used as a trial test of E. coli O157 in large batches of samples.

description: The increasingly complex challenges of making water management more sustainable require a critical and detailed understanding of the social organisation of water. This paper examines the hitherto neglected role that 'intermediary' organisations play in reshaping the relations between the provision and use of water and sanitation services. In response to new regulatory, environmental, social, and commercial pressures the relationships between water utilities, consumers, and regulators are changing, creating openings for both new and existing organisations to take on intermediary functions. Drawing on recent EU-funded research we provide the first systematic analysis of intermediary organisations in the European water sector, examining the contexts of their emergence, the ways they work, the functions they perform, and the impacts they can have. With a combination of conceptual and empirical analysis we substantiate and elaborate the case for appreciating the often hidden work of intermediaries. We caution, however, against over-simplistic conclusions on harnessing this potential, highlighting instead the need to reframe perspectives on how water is organised to contemplate actor constellations and interactions beyond the common triad of provider, consumer, and regulator.

description: We report the discovery of the resolved disk around HD 131835 and present the analysis and modeling of its thermal emission. HD 131835 is a ~15 Myr A2 star in the Scorpius-Centaurus OB association at a distance of 122.7 +16.2 -12.8 parsec. The extended disk has been detected to ~1.5" (200 AU) at 11.7 μm and 18.3 μm with T-ReCS on Gemini South. The disk is inclined at an angle of ~75° with the position angle of ~61°. The flux of HD 131835 system is 49.3+-7.6 mJy and 84+-45 mJy at 11.7 μm and 18.3 μm respectively. A model with three grain populations gives a satisfactory fit to both the spectral energy distribution and the images simultaneously. This best-fit model is composed of a hot continuous power-law disk and two rings. We characterized the grain temperature profile and found that the grains in all three populations are emitting at temperatures higher than blackbodies. In particular, the grains in the continuous disk are unusually warm; even when considering small graphite particles as the composition.

Zooming in on 'Zoom fatigue' through a MRT lens
Creators: Decker, Shelly
Publisher: name: University of Alberta Library
Year: 2023

This case study explores what Media Richness Theory (Daft and Lengel, 1986) may offer as a theory to explain employee “Zoom fatigue” during COVID-19 and also examines potential fatigue-related gender differences that may affect our understanding of the theory. This project sought experiences from participants in two focus groups, conducted online, using questions based on an MRT framework and an adapted 15-point Zoom Exhaustion & Fatigue Scale. Data was assessed using narrative analysis to determine content themes. This qualitative study revealed that people want media choice to be intentional and align with communications complexity with failure in these areas potentially resulting in fatigue, disengagement and ineffectiveness, which aligns with MRT. The results also indicate that MRT has numerous shortcomings, including failing to account for gender differences, preferences and complex media which can lead to nonverbal overload, all factors that can contribute to employee fatigue when using video conferencing.

description: The analysis of the frequency dependence of the observed shift of the cores of relativistic jets in active galactic nuclei (AGN) allows us to evaluate the number density of the outflowing plasma n and, hence, the multiplicity parameter, which is a ratio of particle number density to Goldreich-Julian number density. We have obtained the median value for the multiplicity parameter to be 3x10^13 and the median value for the Michel magnetization parameter is 8 from an analysis of 97 sources. Since the magnetization parameter can be interpreted as the maximum possible Lorentz factor of the bulk motion which can be obtained for relativistic magnetohydrodynamic (MHD) flow, this estimate is in agreement with the observed superluminal motion of bright features in AGN jets. Moreover, knowing these key parameters, one can determine the transverse structure of the flow. We show that the poloidal magnetic field and particle number density are much larger in the center of the jet than near the at boundary. The MHD model can also explain the typical observed level of jet acceleration. Finally, casual connectivity of strongly collimated jets is discussed.

description: In classical chaotic systems the entropy, averaged over initial phase space distributions, follows a universal behavior. While approaching thermal equilibrium it passes through a stage where it grows linearly, while the growth rate, the Kolmogorov-Sinai entropy (rate), is given by the sum over all positive Lyapunov exponents. A natural question is whether a similar relation is valid for quantum systems. We argue that the Maldacena-Shenker-Stanford bound on quantum Lyapunov exponents implies that the upper bound on the growth rate of the entropy, averaged over states in Hilbert space that evolve towards a thermal state with temperature T, should be given by πT times the thermal state’s von Neumann entropy. Strongly coupled, large N theories with black hole duals should saturate the bound. To test this we study a large number of isotropization processes of random, spatially homogeneous, far from equilibrium initial states in large N, N = 4 Super Yang Mills theory at strong coupling and compute the ensemble averaged growth rate of the dual black hole’s apparent horizon area. We find both an analogous behavior as in classical chaotic systems and numerical evidence that the conjectured bound on averaged entropy growth is saturated granted that the Lyapunov exponents are degenerate and given by λi = ±2πT. This fits to the behavior of classical systems with plus/minus symmetric Lyapunov spectra, a symmetry which implies the validity of Liouville’s theorem.

description: We report the experimental observation of spin-orbit torque induced switching of perpendicularly magnetized Pt/Co elements in a time resolved stroboscopic experiment based on high resolution Kerr microscopy. Magnetization dynamics is induced by injecting subnanosecond current pulses into the bilayer while simultaneously applying static in-plane magnetic bias fields. Highly reproducible homogeneous switching on time scales of several tens of nanoseconds is observed. Our findings can be corroborated using micromagnetic modeling only when including a fieldlike torque term as well as the Dzyaloshinskii-Moriya interaction mediated by finite temperature.

description: \We present the sixth catalog of Kepler candidate planets based on nearly 4 years of high precision photometry. This catalog builds on the legacy of previous catalogs released by the Kepler project and includes 1493 new Kepler Objects of Interest (KOIs) of which 554 are planet candidates, and 131 of these candidates have best fit radii <1.5 R_earth. This brings the total number of KOIs and planet candidates to 7305 and 4173 respectively. We suspect that many of these new candidates at the low signal-to-noise limit may be false alarms created by instrumental noise, and discuss our efforts to identify such objects. We re-evaluate all previously published KOIs with orbital periods of >50 days to provide a consistently vetted sample that can be used to improve planet occurrence rate calculations. We discuss the performance of our planet detection algorithms, and the consistency of our vetting products. The full catalog is publicly available at the NASA Exoplanet Archive.

description: This paper studies networks with N half-duplex relays assisting the communication between a source and a destination. In ISIT'12 Brahma, Özgür and Fragouli conjectured that in Gaussian half-duplex diamond networks (i.e., without a direct link between the source and the destination, and with N non-interfering relays) an approximately optimal relay scheduling policy (i.e., achieving the cut-set upper bound to within a constant gap) has at most N+1 active states (i.e., at most N+1 out of the $2^N$ possible relay listen-transmit states have a strictly positive probability). Such relay scheduling policies were referred to as simple. In ITW'13 we conjectured that simple approximately optimal relay scheduling policies exist for any Gaussian half-duplex multi-relay network irrespectively of the topology. This paper formally proves this more general version of the conjecture and shows it holds beyond Gaussian noise networks. In particular, for any memoryless half-duplex N-relay network with independent noises and for which independent inputs are approximately optimal in the cut-set upper bound, an approximately optimal simple relay scheduling policy exists. A convergent iterative polynomial-time algorithm, which alternates between minimizing a submodular function and maximizing a linear program, is proposed to find the approximately optimal simple relay schedule. As an example, for N-relay Gaussian networks with independent noises, where each node in equipped with multiple antennas and where each antenna can be configured to listen or transmit irrespectively of the others, the existence of an approximately optimal simple relay scheduling policy with at most N+1 active states is proved. Through a line-network example it is also shown that independently switching the antennas at each relay can provide a strictly larger multiplexing gain compared to using the antennas for the same purpose.

description: We develop a method of transverse momentum dependent (TMD) operator expansion that yields the TMD factorization theorem on the operator level. The TMD operators are systematically ordered with respect to TMD-twist, which allows a certain separation of kinematic and genuine power corrections. The process dependence enters via the boundary conditions for the background fields. As a proof of principle, we derive the effective operator for hadronic tensor in TMD factorization up to the next-to-leading power (∼ qT/Q) at the next-to-leading order for any process with two detected states.
Diffuse emission of high-energy neutrinos from gamma-ray burst fireballs

description: Gamma-ray bursts (GRBs) have been suggested as possible sources of the high-energy neutrino flux recently detected by the IceCube telescope. We revisit the fireball emission model and elaborate an analytical prescription to estimate the high-energy neutrino prompt emission from pion and kaon decays, assuming that the leading mechanism for the neutrino production is lepto-hadronic. To this purpose, we include hadronic, radiative and adiabatic cooling effects and discuss their relevance for long- (including high- and low-luminosity) and short-duration GRBs. The expected diffuse neutrino background is derived, by requiring that the GRB high-energy neutrino counterparts follow up-to-date gamma-ray luminosity functions and redshift evolutions of the long and short GRBs. Although dedicated stacking searches have been unsuccessful up to now, we find that GRBs could contribute up to a few % to the observed IceCube high-energy neutrino flux for sub-PeV energies, assuming that the latter has a diffuse origin. Gamma-ray bursts, especially low-luminosity ones, could however be the main sources of the IceCube high-energy neutrino flux in the PeV range. While high-luminosity and low-luminosity GRBs have comparable intensities, the contribution from the short-duration component is significantly smaller. Our findings confirm the most-recent IceCube results on the GRB searches and suggest that larger exposure is mandatory to detect high-energy neutrinos from high-luminosity GRBs in the near future.

description: Gasification as a method for adjustment of the surface properties of biochar is investigated in this work. Uncontaminated biomass from Pinus sylvestris Scots pine is utilized as the feedstock. This material is later transformed into biochar by submission to the torrefaction process in an inert atmosphere at 300°C for 45 minutes and further activated via gasification. The main goal of the work is to obtain a product with suitable physical characteristics for a post-processing step which consists of passivation by encapsulation within a coke tar layer. Since literature findings suggest higher BET surface areas and porosity production, the thermochemical activation is performed with CO2 as the oxidizing agent. Reaction conditions such as temperature, residence time, and type of reactor are selected considering the state of the art of gasification for the activation of biochar. The parameters are varied to obtain twelve materials with different physical properties. The produced samples from the lab-scale experiments are later characterized via light microscopy, SEM analysis, and physisorption analysis. The results show that an increase in temperature and residence time produces higher burn-off values achieving 87,1% in the fixed bed and 74,2% in the fluidized bed, both experiments performed at 900°C for 25 minutes. This behavior is related to the formation of higher specific surface area and porosity, achieving surface BET area values of 904 m2/g and 516 m2 g, and pore volumes of 0,4897 cm3/g and 0,2632 cm3/g, respectively, which is significantly higher than the 0,6483 m2/g and 0,00092 cm3/g values of the torrefied biochar. SEM analysis demonstrated more significant degradation of the structure, as pores and several fragmentations appeared in the surface layer of the biochar. The main findings from the present thesis are as follows: i) Torrefaction proved to be a suitable process for biochar production; ii) Activation temperature plays a vital role in the gasification of biochar as an increase from 800°C to 900°C produces higher degradation and porosity formation, therefore, increasing the surface area; iii) Temperature, residence time, and type of reactor influences the burn-off and porosity of the activated biochar; iii) Fixed bed shows better results regarding the surface area and porosity in comparison with the fluidized bed in the conditions of 900°C and 25 minutes residence time. These results constitute the basis of further investigations where contaminated biomass can be used as a precursor in different thermochemical processes to obtain high-value-added products and unreactive and stable biochar.

description: We compute the second moments of pion and rho parton distribution functions in lattice QCD with Nf=2+1 flavors of improved Wilson fermions. We determine both singlet and nonsinglet flavor combinations and, for the first time, take disconnected contributions fully into account. In the case of the rho, we also calculate the additional contribution arising from the b1 structure function. The numerical analysis includes 26 ensembles, mainly generated by the CLS effort, with pion masses ranging from 420 down to 214 MeV and with 5 different lattice spacings in the range of 0.1 to 0.05 fm. This enables us to take the continuum limit, as well as to resolve the quark mass dependencies reliably. Additionally we discuss the contaminations of rho correlation functions by two-pion states.

description: Future direct observations of extrasolar Earth-sized planets in the habitable zone could be hampered by a worrisome source of noise, starlight-reflecting exozodiacal dust. Mid-infrared surveys are currently underway to constrain the amount of exozodiacal dust in the habitable zones around nearby stars. However, at visible wavelengths another source of dust, invisible to these surveys, may dominate over exozodiacal dust. For systems observed near edge-on, a cloud of dust with face-on optical depth 10^-7 beyond ~5 AU can mimic the surface brightness of a cloud of exozodiacal dust with equal optical depth if the dust grains are sufficiently forward-scattering. We posit that dust migrating inward from cold debris belts via Poynting-Robertson drag could produce this "pseudo-zodiacal" effect, potentially making it ~50% as common as exozodiacal clouds. We place constraints on the disk radii and scattering phase function required to produce the effect.
