description: The development of information infrastructures in healthcare is often described in abstract terms as datafication, the conversion of qualitative aspects of life into quantified data, which makes the people and actual work involved invisible. To make visible the actors and the efforts implied in the term ‘datafication’, in this paper, we describe two emergent data work occupations in healthcare: Medical scribes and clinical documentation improvement specialists (CDIS). These cases provide a starting point for understanding the impacts of digitization of healthcare and the emergence of new kinds of work and new occupations that health organizations adapted to accommodate such impacts. Making data work visible is important in order for these occupations to be acknowledged. If data work remains invisible, healthcare organizations and researchers alike will have an incomplete understanding of how data is actually produced in practice, hindering the organizational design, human resources, and organizational learning that are essential for healthcare organizations to become competent producers and users of data.

description: The physics of interacting quantum wires has attracted a lot of attention recently. When the density of electrons in the wire is very low, the strong repulsion between electrons leads to the formation of a Wigner crystal. We review the rich spin and orbital properties of the Wigner crystal, both in the one-dimensional and quasi-one-dimensional regime. In the one-dimensional Wigner crystal the electron spins form an antiferromagnetic Heisenberg chain with exponentially small exchange coupling. In the presence of leads the resulting inhomogeneity of the electron density causes a violation of spin-charge separation. As a consequence the spin degrees of freedom affect the conductance of the wire. Upon increasing the electron density, the Wigner crystal starts deviating from the strictly one-dimensional geometry, forming a zigzag structure instead. Spin interactions in this regime are dominated by ring exchanges, and the phase diagram of the resulting zigzag spin chain has a number of unpolarized phases as well as regions of complete and partial spin polarization. Finally we address the orbital properties in the vicinity of the transition from a one-dimensional to a quasi-one-dimensional state. Due to the locking between chains in the zigzag Wigner crystal, only one gapless mode exists. Manifestations of Wigner crystal physics at weak interactions are explored by studying the fate of the additional gapped low-energy mode as a function of interaction strength.

Year: 2019

description: As Workplace Health Promotion (WHP) initiatives are gaining relevance in welfare programmes, employers are becoming more interested in ensuring that workers, particularly those at risk, can benefit from guidance in following lifestyle intervention that can reduce extra costs for the companies who employ them. This opens new possibilities for dedicated health infrastructures in the workplace enabling health information sharing and connecting various stakeholders, such as doctors, employees, employers, data protection officers, designers. In this paper we describe DMCoach+, a platform aimed at supporting healthy lifestyles at work- Overall a group of 120 users are followed by a physician as coach for six months assisting them getting aware of their basic parameters (heart rate, BMI, waistline, activity time) and, through a gamified experience, improve their condition. The aim of this paper is to provide a preliminary discussion to understand how stakeholders and users across three pilots (two in Italy and one in the Netherlands) have planned the use of the app DMCoach+, which was provided by their work organisations as part of a more widespread health welfare infrastructure. The paper features a preliminary discussion about the main findings about the stakeholder’s workaround to shape the infrastructure designed for people and organisations that have voluntarily participated in a pilot to prevent illness in the workplace.

Holographic Joule-Thomson Expansion in Lower Dimensions

description: The thermodynamical process of Joule-Thomson expansion is extended to the lower-dimensional spacetimes by considering rotating, charged and charged rotating BTZ black hole metrics. The Joule-Thomson coefficients, the inversion curves and the isenthalps are found for all three cases. From the behavior of inversion curves in the $T-P$ plane, it is observed that there exists only minimum inversion temperatures for BTZ black holes. The relevant calculations for rotating BTZ black holes are almost straightforward, while it is more challenging to address when a charge parameter is added. In the case of charged BTZ metrics, the black hole system can be considered in two possible thermodynamical schemes and it is explicitly proved that the Joule-Thomson expansion is present in a specific scheme (referred to as scheme II) in which thermodynamic instabilities do not arise. The existence of Joule-Thomson expansion in all three BTZ cases strongly indicates that these lower-dimensional black hole spacetimes can be considered as interacting statistical systems like their higher-dimensional cousins.

description: We study the dynamics of Bose-Einstein condensates flowing in optical lattices on the basis of quantum field theory. For such a system, a Bose-Einstein condensate shows a unstable behavior which is called the dynamical instability. The unstable system is characterized by the appearance of modes with complex eigenvalues. Expanding the field operator in terms of excitation modes including complex ones, we attempt to diagonalize the unperturbative Hamiltonian and to find its eigenstates. It turns out that although the unperturbed Hamiltonian is not diagonalizable in the conventional bosonic representation the appropriate choice of physical states leads to a consistent formulation. Then we analyze the dynamics of the system in the regime of the linear response theory. Its numerical results are consitent with as those given by the discrete nonlinear Schrodinger equation.

description: The scaling of the longitudinal velocity structure functions, $S_q(r) = < | δu (r) |^q > \sim r^{ζ_q}$, is analyzed up to order $q=8$ in a decaying rotating turbulence experiment from a large Particle Image Velocimetry (PIV) dataset. The exponent of the second-order structure function, $ζ_2$, increases throughout the self-similar decay regime, up to the Ekman time scale. The normalized higher-order exponents, $ζ_q / ζ_2$, are close to those of the intermittent non-rotating case at small times, but show a marked departure at larger times, on a time scale $Ω^{-1}$ ($Ω$ is the rotation rate), although a strictly non-intermittent linear law $ζ_q / ζ_2 = q/2$ is not reached.

description: We report a novel phenomenon in carbon nanotube (CNT) based devices, the transphonon effects, which resemble the transonic effects in aerodynamics. It is caused by dissipative resonance of nanotube phonons similar to the radial breathing mode, and subsequent drastic surge of the dragging force on the sliding tube, and multiple phonon barriers are encountered as the intertube sliding velocity reaches critical values. It is found that the transphonon effects can be tuned by applying geometric constraints or varying chirality combinations of the nanotubes.

A possible mechanism of concurring diagonal and off-diagonal long-range order for soft interactions

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: This paper is a contribution to the theory of coherent crystals. We present arguments claiming that negative minima in the Fourier transform of a soft pair interaction may give rise to the coexistence of diagonal and off-diagonal long-range order at high densities, and that this coexistence may be detectable due to a periodicity seen on the off-diagonal part of the one-body reduced density matrix, without breaking translation invariance. As an illustration, we study the ground state of a homogenous system of bosons in continuous space, from the interaction retaining only the Fourier modes $v(\k)$ belonging to a single nonzero wave number $|\k|=q$. The result is a mean-field model. We prove that for $v(\k)>0$ the ground state is asymptotically fully Bose-condensed, while for $v(\k)<0$ at densities exceeding a multiple of $\hbar^2 q^2/2m|v(\k)|$ it exhibits both Bose-Einstein condensation and diagonal long-range order, and the latter can be seen on both the one- and the two-body density matrix.

description: This paper explores how the Colombian MIPRES system emerged as a nationwide ePrescription solution and, how it evolved into a backbone for the country’s Information Infrastructure. Our empirical qualitative study is based on the analysis of interviews conducted in the Ministry of Health, hospitals, insurance companies and patients’ organizations. In addition, documents and notes from ethnographic observations were analyzed. Information Infrastructure theoretical insights were employed to analyze the contextual conditions that shaped this evolution. Initially, MIPRES was conceived as a simple reporting system. Through its non-threatening strategy and alliances, it gained momentum like a snowball and, grew to become a central component of the Colombian health information infrastructure. Considered a “successful” implementation, MIPRES triggered a new network of relationships that exists in the background, it is invisible, and frequently taken for granted; thus we conclude that MIPRES wove around it the health information infrastructure of Colombia.

description: In order to train robust deep learning models, large amounts of labelled data is required. However, in the absence of such large repositories of labelled data, unlabeled data can be exploited for the same. Semi-Supervised learning aims to utilize such unlabeled data for training classification models. Recent progress of self-training based approaches have shown promise in this area, which leads to this study where we utilize an ensemble approach for the same. A by-product of any semi-supervised approach may be loss of calibration of the trained model especially in scenarios where unlabeled data may contain out-of-distribution samples, which leads to this investigation on how to adapt to such effects. Our proposed algorithm carefully avoids common pitfalls in utilizing unlabeled data and leads to a more accurate and calibrated supervised model compared to vanilla self-training based student-teacher algorithms. We perform several experiments on the popular STL-10 database followed by an extensive analysis of our approach and study its effects on model accuracy and calibration.

description: In this article and in its sequel we propose the study of certain discretizations of geometric evolution equations as an approach to the study of the existence problem of some elliptic partial differential equations of a geometric nature as well as a means to obtain interesting dynamics on certain infinite-dimensional spaces. We illustrate the fruitfulness of this approach in the context of the Ricci flow, as well as another flow, in Kahler geometry. We introduce and study dynamical systems related to the Ricci operator on the space of Kahler metrics that arise as discretizations of these flows. We pose some problems regarding their dynamics. We point out a number of applications to well-studied objects in Kahler and conformal geometry such as constant scalar curvature metrics, Kahler-Ricci solitons, Nadel-type multiplier ideal sheaves, balanced metrics, the Moser-Trudinger-Onofri inequality, energy functionals and the geometry and structure of the space of Kahler metrics. E.g., we obtain a new sharp inequality strengthening the classical Moser-Trudinger-Onofri inequality on the two-sphere.
Studies on the entry of alphaviruses into BHK-21 cells
Creators: name: Talbot, Pierre
Publisher: name: University of British Columbia
Year: 2010

description: The nature of the infectious mechanism of entry of alphaviruses into cultured BHK-21 cells was studied. The importance of cellular lysosomes in a productive Sindbis virus infection was determined. Chloroquine (100 μM) and NH₄Cl (10 mM), known inhibitors of lysosomal function, decreased the production of infectious Sindbis virions in BHK-21 cells by 10- and 12-fold respectively, when present during the 1 h infection period of a plaque assay. There were no apparent toxic effects on cells exposed to these chemicals, with the exception of a reversible 2-fold inhibition of cellular protein synthesis by chloroquine. In order to determine if the decrease in the virus titer was correlated with a similar decrease in the number of virus particles, the reduction in the formation of Sindbis virions was monitored by incorporation of Ḻ-[³⁵S]methionine and shown to be 2-fold at 8 and 11 h post-infection. Shedding of envelope glycoproteins into the culture medium was indirectly demonstrated by the fact that much more of these proteins were released that can be accounted for by progeny virions. Finally, the importance of a lysosomal pathway of infection was studied in more details. Cells were infected with Sindbis virus labelled with Ḻ-[³⁵S]methionine and the fate of radiolabeled viral proteins into subcellular fractions followed up to 120 min post-infection. Viruses were transiently associated with a cell fraction enriched in lysosomes. Capsid proteins were preferentially released into the cytoplasm after 60 min post-infection and viral proteins started to be significantly degraded between the first and second hour after infection. Chloroquine produced an initial accumulation of viruses in the lysosomes at 20 min post-infection and these trapped particles appeared to be degraded thereafter. Unexpectedly, NH₄Cl blocked an early infection step between binding of the virus on the cell surface and penetration into lysosomes, possibly receptor clustering into coated pits or receptor recycling. Results were identical with virus preparations which contained either 147 or 36 particles per infective unit. In conclusion, the results of these studies strongly suggest the involvement of lysosomes and thus a receptor-mediated endocytic pathway (viropexis) as the main infectious mechanism for entry of Sindbis virus into BHK-21 cells. The mechanism of entry of radiolabeled Semliki Forest virus was also studied. After a 15 min pulse, whole virus particles migrated within 60 min from a fraction of the cells enriched in plasma membranes into an intracellular fraction (endoplasmic reticulum). This result is consistent with an endocytic mechanism of entry.

description: We study solutions to nonlinear stochastic differential systems driven by a multi-dimensional Wiener process. A useful algorithm for strongly simulating such stochastic systems is the Castell--Gaines method, which is based on the exponential Lie series. When the diffusion vector fields commute, it has been proved that at low orders this method is more accurate in the mean-square error than corresponding stochastic Taylor methods. However it has also been shown that when the diffusion vector fields do not commute, this is not true for strong order one methods. Here we prove that when there is no drift, and the diffusion vector fields do not commute, the exponential Lie series is usurped by the sinh-log series. In other words, the mean-square error associated with a numerical method based on the sinh-log series, is always smaller than the corresponding stochastic Taylor error, in fact to all orders. Our proof utilizes the underlying Hopf algebra structure of these series, and a two-alphabet associative algebra of shuffle and concatenation operations. We illustrate the benefits of the proposed series in numerical studies.

description: The following paper has been motivated from recent works of Kremer, G.M [1, 4], Vardiashvili, G [2], Jantsch, R.C [3], Capozziello, S [5] on Van-Der-Waals EOS cosmology. The main aim for this paper is to analyze the thermodynamics of a Non-linear system which in this case is Van-Der-Waals fluid EOS [6]. We have investigated the Van-Der-Waals fluid system with the generalized EOS as [8]. The third term signifies viscosity which has been considered as an external parameter that only modifies pressure but not the density of the liquid. The and are the two functions of energy density and time that are different for the 3 types of Vander Waal models namely one parameter model, two parameters model and three parameters model [7, 9]. The value of EOS parameter [6, 10] will show different values for different models. We have studied the changes in the parameters for different cosmic phases [4, 5, 6]. We have also studied the thermodynamics and the stability conditions for the three models while considering viscosity [10, 12, 13, 14]. We have discussed the importance of viscosity [11] for explaining accelerating universe with negative pressure [12]. Finally, we have resolved the finite time future singularity problems [15-20] and discussed the thermodynamics energy conditions [21-31] with those models.

description: Context.Recent study of SDSS J1257+3419 has revealed that this stellar system is either a faint and small dwarf galaxy or a faint and widely extended globular cluster (see also arXiv:0709.0327 [astro-ph]). Aims.In this short note, the author suggests that this system is one of the smallest dwarf spheroidals (dSphs) in the Milky Way. Methods.We re-examine some observational quantities of this object and check whether it can be bound system. Results. As a result, we find the mass of SDSS J1257+3419 is the lowest of dSphs in the Milky Way, and its mass density is typical of dSphs. Important is that the tidal radius of SDSS J1257+3419 is much larger than its half-light radius. That is, this very small dSph can be bound by its own gravity.

description: The most intriguing question related to the chemical evolution of protoplanetary disks is the genesis of pre-biotic organic molecules in the planet-forming zone. In this contribution we briefly review current observational knowledge of physical structure and chemical composition of disks and discuss whether organic molecules can be present in large amounts at the verge of planet formation. We predict that some molecules, including CO-bearing species such as H$_2$CO, can be underabundant in inner regions of accreting protoplanetary disks around low-mass stars due to the high-energy stellar radiation and chemical processing on dust grain surfaces. These theoretical predictions are further compared with high-resolution observational data and the limitations of current models are discussed.

description: The mechanical response of graphene nano-ribbon under tensile loading has been investigated using atomistic simulation. Lattice symmetry dependence of elastic properties are found, which fits prediction from Cauchy-Born rule well. Concurrent brittle and ductile behaviors are observed in the failure process at elastic limit, which dominates at low and high temperature respectively. In addition, the free edges of finite width ribbon help to activate bond-flip events and initialize ductile behavior.
Slow long-range decay of bound Hartree-Fock orbitals and enhancement of the exchange interaction and tunneling

description: Exchange interaction strongly influences the long-range behaviour of localised electron orbitals. It violates the oscillation theorem (creates extra nodes) and produces a power-law decay instead of the usual exponential decrease at large distances. For inner orbitals inside molecules decay is 1/r^2, for macroscopic systems cos(k_f r)/r^n, where k_f is the Fermi momentum and n=3 for 1D, n=3.5 for 2D and n=4 for 3D crystal. Slow decay increases the exchange interaction between localised spins and the under-barrier tunneling amplitude.The under-barrier transmission coefficients in solids (e.g. for point contacts) become temperature-dependent.

description: We present a simple derivation of the matrix Riccati equations governing the reduced dynamics as one descends from the group U(N) describing the Schroedinger evolution of an N-level quantum system to the various coset spaces, Grassmanian manifolds, associated with it. The special case pertaining to the geometric phase in N-level systems is described in detail. Further, we show how the matrix Riccati equation thus obtained can be reformulated as an equation describing Hamiltonian evolution in a classical phase space and establish correspondences between the two descriptions.

description: There exists a class of nuclei that are obtained by adding one nucleon to a loosely-bound nucleon-core system, for example $^{12}$Be, $^9$C, $^{18}$Ne. For such nuclei, one-nucleon overlap integrals that represent single-particle motion can strongly differ from the standard ones due to the correlations between the two nucleons above the core. The possible non-standard overlap behaviour should be included in the interpretation of the experimental data derived from one nucleon removal reactions such as knockout, transfer and breakup, as well as the predictions of low-energy nucleon capture that leads to these nuclei. We investigate the non-standard behaviour within a three-body model and discuss the challenges associated with this problem.

description: Many fundamental physical processes regarding planetary formation in protoplanetary disks are still imperfectly understood, with an elusive phenomenon being turbulence in such disks. Observations are available of planetary systems and of some protoplanetary disks, which can serve as a starting point for these investigations. Detected systems reveal different architectures of planets. One particularly interesting case to consider is the Kepler-223 system, which contains a rare configuration of four planets in a resonance chain, implying a certain migration history. We aim to use the orbital configuration of Kepler-223's planets to constrain the parameters of the protoplanetary disk that allow for the formation of a chain of mean-motion resonances that resembles the one of Kepler-223. The parameters we aim to investigate are primarily the disk viscosity and surface density. We use the swift_symba N-body integrator with additional dissipative forces to mimic planet-disk interactions. We constrain the surface densities and viscosities that allow the formation of a resonant chain like that of Kepler-223. We find that surface densities of up to a few minimum mass solar nebula (MMSN) surface densities and disk viscosity parameters $α$ of a few $10^{-3}$ up to $10^{-2}$ are most successful at reproducing the architecture of this particular planetary system. We describe how these two quantities are linked to each other considering the success of reproducing the chain and find that higher disk surface densities in turn require lower viscosities to build the chain. Our results show that well characterized observed planetary systems hold information about their formation conditions in the protoplanetary disks and that it is possible to extract this information, namely the initial disk surface density and viscosity, helping to constrain planet formation.

description: In this paper we have studied Van-Der-Waals fluid system with the generalized EOS as as discussed in the recent works of Kremer, G.M [1, 4], Vardiashvili, G [2], Jantsch, R.C [3], Capozziello, S [5]. and are functions of energy density and time that are different for the three types of Van der Waals fluid which are one parameter model, two parameters model and three parameters model. We have studied the changes in the parameters for different cosmic phases. We have also investigated the thermodynamics and the stability conditions for these three models. Finally, we have resolved the finite time future singularity problems

An evaluation of possible mechanisms for anomalous resistivity in the solar corona

description: A wide variety of transient events in the solar corona seem to require explanations that invoke fast reconnection. Theoretical models explaining fast reconnection often rely on enhanced resistivity. We start with data derived from observed reconnection rates in solar flares and seek to reconcile them with the chaos-induced resistivity model of Numata & Yoshida (2002) and with resistivity arising out of the kinetic Alfvén wave (KAW) instability. We find that the resistivities arising from either of these mechanisms, when localized over lengthscales of the order of an ion skin depth, are capable of explaining the observationally mandated Lundquist numbers.

Varying the Universality of Supersymmetry-Breaking Contributions to MSSM Higgs Boson Masses

description: We consider the minimal supersymmetric extension of the Standard Model (MSSM) with varying amounts of non-universality in the soft supersymmetry-breaking contributions to the Higgs scalar masses. In addition to the constrained MSSM (CMSSM) in which these are universal with the soft supersymmetry-breaking contributions to the squark and slepton masses at the input GUT scale, we consider scenarios in which both the Higgs scalar masses are non-universal by the same amount (NUHM1), and scenarios in which they are independently non-universal (NUHM2). We show how the NUHM1 scenarios generalize the (m_{1/2}, m_0) planes of the CMSSM by allowing either mu or m_A to take different (fixed) values and we also show how the NUHM1 scenarios are embedded as special cases of the more general NUHM2 scenarios. Generalizing from the CMSSM, we find regions of the NUHM1 parameter space that are excluded because the LSP is a selectron. We also find new regions where the neutralino relic density falls within the range preferred by astrophysical and cosmological measurements, thanks to rapid annihilation through direct-channel Higgs poles, or coannihilation with selectrons, or because the LSP composition crosses over from being mainly bino to mainly Higgsino. Generalizing further to the NUHM2, we find regions of its parameter space where a sneutrino is the LSP, and others where neutralino coannihilation with sneutrinos is important for the relic density. In both the NUHM1 and the NUHM2, there are slivers of parameter space where the LHC has fewer prospects for discovering sparticles than in the CMSSM, because either m_{1/2} and/or m_0 may be considerably larger than in the CMSSM.

description: We conduct molecular dynamics simulations of the collision of atomic clusters with a weakly-attractive surface. We focus on an intermediate regime, between soft-landing and fragmentation, where the cluster undergoes deformation on impact but remains largely intact, and will either adhere to the surface (and possibly slide), or be reflected. We find that the outcome of the collision is determined by the Weber number, We i.e. the ratio of the kinetic energy to the adhesion energy, with a transition between adhesion and reflection occurring as We passes through unity. We also identify two distinct collision regimes: in one regime the collision is largely elastic and deformation of the cluster is relatively small but in the second regime the deformation is large and the adhesion energy starts to depend on the kinetic energy. If the transition between these two regimes occurs at a similar kinetic energy to that of the transition between reflection and adhesion, then we find that the probability of adhesion for a cluster can be bimodal. In addition we investigate the effects of the angle of incidence on adhesion and reflection. Finally we compare our findings both with recent experimental results and with macroscopic theories of particle collisions.

description: The variation of the resonance poles, i.e., the mass and width, originating from changing the values of $N_C$, the number of the QCD colors, provide an intuitive theoretical method to discriminate the interior constituents of hadrons. Many different approaches, including unitarized chiral amplitudes, dispersive methods, quark models, linear-sigma-model-like framework, etc., have been widely used to determine the $N_C$ trajectories of the various resonance pole positions. We focus on the discussions of the light-flavor meson resonances in this work.

description: Contexte : Les patients atteints d’un double diagnostic de troubles schizophréniques et de troubles de la consommation de substances mettent à mal les structures de soins psychiatriques de par la complexité de la prise en charge. Objectif : Ce travail vise à identifier les outils menant au rétablissement pour les patients atteints de schizophrénie et d’addiction au cannabis. Méthode : La sélection d’articles scientifiques a eu pour critères d’inclusion : une population adulte ; tous sexes confondus ; articles en français et anglais ; schizophrénie et addiction à une substance. Deux bases de données ont été utilisées : CINAHL et PubMed. La recherche documentaire nous a permis de dégager six articles, que nous avons analysés à l’aide des grilles de Fortin. Résultats : Les traitements intégrés se basant sur la gestion de la consommation de substances ainsi que des troubles psychiatriques sont ressortis comme nettement plus bénéfiques pour les individus que le traitement d’une seule pathologie. Les bénéficiaires étant pris en charge de manière plus complète ont démontré des améliorations au niveau de leurs troubles et d’un point de vue social. Discussion : Les résultats ressortis démontrent, qu’une prise en charge individualisée, pluridisciplinaire et globale est essentielle au rétablissement de cette population. Ceux-ci nous ont aussi permis d’établir quelques recommandations d’interventions comme : l’entretien motivationnel (individuel ou de groupe), l’aide à la gestion des symptômes psychiatriques, une assistance aux habilités sociales, l’aide au logement et à l’emploi. Les traitements intégrés, qui prennent en compte à la fois les symptômes psychiatriques et les problématiques d’addictions, ont montré leur plus-value dans la prise en charge.
