title: A comparison of different community models of Antiretroviral Therapy delivery among stable HIV+ patients in an urban setting, Zambia. A cluster-randomized non-inferiority trial.
Creators: name: Limbada, M
Publisher: name: London School of Hygiene & Tropical Medicine
Year: 2021

description: Background: Community models of antiretroviral therapy (ART) delivery also known as differentiated service delivery (DSD) models are a novel innovative strategy to increase sustainable ART coverage for people living with HIV (PLHIV) in resource-limited settings. We compared two different models of ART delivery with the health care facility to gather evidence on the impact of these models’ patients’ clinical and virological outcomes, operational feasibility, and acceptability to guide policy makers on which models to roll out in the context of universal treatment. Methods: A three-arm cluster randomized non-inferiority trial was conducted in two urban HPTN 071 trial communities in Zambia comparing three different models of ART delivery: Standard of Care (SoC), Home-Based delivery (HBD) and Adherence Clubs (AC). Adult HIV+ patients defined as “stable” on ART, were eligible for inclusion. The primary endpoint was the proportion of PLHIV with virological suppression (≤1000 copies HIV RNA/ml) at 12 months (+/- 3 months) after study entry across all three arms. Analysis of our outcomes used statistical methods for CRT. Results: A total of 2,489 participants were enrolled in the study (781 SoC, 852 HBD, and 856 AC). There was a strong evidence (p<0.001) that both community models of ART delivery were non-inferior to SoC. The proportion of virological suppression in our three study arms > 95% compares favourably or superiorly with results published from literature. This trial also identified gaps in the evidence base and programmatic priorities for DSD implementation in SSA in the coming years with respect to viral load testing and monitoring and evaluation of DSD models embedded in routine HIV service delivery. Discussion: Community models of ART delivery were as effective as facility-based care in terms of viral suppression. However, availability of viral load test results remains a challenge to HIV programmes and could undermine gains from universal treatment. Offering PLHIV choices of these different models of ART is feasible and acceptable.

description: We analyzed intermittency in the solar wind, as observed on the ecliptic plane, looking at magnetic field and velocity fluctuations between 0.3 and 1 AU, for both fast and slow wind and for compressive and directional fluctuations. Our analysis focused on the property that probability distribution functions of a fluctuating field affected by intermittency become more and more peaked at smaller and smaller scales. Since the peakedness of a distribution is measured by its flatness factor we studied the behavior of this parameter for different scales to estimate the degree of intermittency of our time series. We confirmed that both magnetic field and velocity fluctuations are rather intermittent and that compressive magnetic fluctuations are generally more intermittent than the corresponding velocity fluctuations. In addition, we observed that compressive fluctuations are always more intermittent than directional fluctuations and that while slow wind intermittency does not depend on the radial distance from the sun, fast wind intermittency of both magnetic field and velocity fluctuations clearly increases with the heliocentric distance....

description: We consider the action principles that are the lower dimensional limits of the Einstein-Gauss-Bonnet gravity {\it via} the Kaluza-Klein route. We study the vacua and obtain some exact solutions. We find that the reality condition of the theories may select one vacuum over the other from the two vacua that typically arise in Einstein-Gauss-Bonnet gravity. We obtain exact black hole and cosmological solutions carrying scalar hair, including scalar hairy BTZ black holes with both mass and angular momentum turned on. We also discuss the holographic central charges in the asymptotic AdS backgrounds.

Expansion Exponents for Nonequilibrium Systems

Subjects: subject: Condensed Matter (cond-mat)

description: Local expansion exponents for nonequilibrium dynamical systems, described by partial differential equations, are introduced. These exponents show whether the system phase volume expands, contracts, or is conserved in time. The ways of calculating the exponents are discussed. The {\it principle of minimal expansion} provides the basis for treating the problem of pattern selection. The exponents are also defined for stochastic dynamical systems. The analysis of the expansion-exponent behaviour for quasi-isolated systems results in the formulation of two other principles: The {\it principle of asymptotic expansion} tells that the phase volumes of quasi-isolated systems expand at asymptotically large times. The {\it principle of time irreversibility} follows from the asymptotic phase expansion, since the direction of time arrow can be defined by the asymptotic expansion of phase volume.

description: We have developed the tight-binding theory to study electronic and optical properties of type-II heterostructures CA/C'A' grown from the zinc-blende semiconductors CA and C'A' along the crystallographic direction [001]. The sp^3s* nearest-neighbor tight-binding model with allowance for the spin-orbit interaction is used to calculate the energy states and the in-plane linear polarization of the spatially-indirect band-edge photoluminescence of InAs/AlSb and ZnSe/BeTe multi-layered structures. The interface parameters for a pair of the nonstandard planes C-A' or C'-A are considered as fitting variables. A wide range of these parameters are shown to allow Tamm-like hole states localized at the interfaces. The theory leads to giant values of the light polarization in the both type-II heterosystems in agreement with existing experimental findings.

description: The escape of hot O and C atoms from the present martian atmosphere during low and high solar activity conditions has been studied with a Monte-Carlo model. The model includes the initial energy distribution of hot atoms, elastic, inelastic, and quenching collisions between the suprathermal atoms and the ambient cooler neutral atmosphere, and applies energy dependent total and differential cross sections for the determination of the collision probability and the scattering angles. The results yield a total loss rate of hot oxygen of $2.3-2.9\times 10^{25}\,{\rm s}^{-1}$ during low and high solar activity conditions and is mainly due to dissociative recombination of O$_2^+$ and CO$_2^+$. The total loss rates of carbon are found to be $0.8$ and $3.2\times 10^{24}\,{\rm s}^{-1}$ for low and high solar activity, respectively, with photodissociation of CO being the main source. Depending on solar activity, the obtained carbon loss rates are up to $\sim 40$ times higher than the CO$_2^+$ ion loss rate inferred from Mars Express ASPERA-3 observations. Finally, collisional effects above the exobase reduce the escape rates by about $20-30\,\%$ with respect to a collionless exophere.

description: Motivated by the brane-world scenarios, we study the absorption problem when the spacetime background is $(4+n)$-dimensional Schwarzschild black hole. We compute the low-energy absorption cross sections for the brane-localized massive scalar, brane-localized massive Dirac fermion, and massive bulk scalar. For the case of brane-localized massive Dirac fermion we introduce the particle's spin in the traditional Dirac form without invoking the Newman-Penrose method. Our direct introduction of spin enables us to compute contributions to the $j$th-level partial absorption cross section from orbital angular momenta $\ell = j \pm 1/2$. It is shown that the contribution from the low $\ell$-level is larger than that from the high $\ell$-level in the massive case. In the massless case these two contributions are exactly same with each other. The ratio of low-energy absorption cross sections for Dirac fermion and for scalar is dependent on the number of extra dimensions as $2^{(n-3)/ (n+1)}$. Thus the ratio factor 1/8 is recovered when $n=0$, which Unruh found. The physical importance of this ratio factor is discussed in the context of the brane-world scenario. For the case of bulk scalar our low-energy absorption cross section for S-wave is exactly same with area of the horizon hypersurface in the massless limt, which is an higher-dimensional generaliztion of universality. Our results for all cases turn out to have correct massless and 4d limits.

description: With the advancements in high volume, low precision computational technology and applied research on cognitive artificially intelligent heuristic systems, machine learning solutions through neural networks with real-time learning has seen an immense interest in the research community as well the industry. This paper involves research, development and experimental analysis of a neural network implemented on a robot with an arm through which evolves to learn to walk in a straight line or as required. The neural network learns using the algorithms of Gradient Descent and Backpropagation. Both the implementation and training of the neural network is done locally on the robot on a raspberry pi 3 so that its learning process is completely independent. The neural network is first tested on a custom simulator developed on MATLAB and then implemented on the raspberry computer. Data at each generation of the evolving network is stored, and analysis both mathematical and graphical is done on the data. Impact of factors like the learning rate and error tolerance on the learning process and final output is analyzed.

 Remarks. —The only previous record of this species from Chile or the entire eastern Pacific was that of Squires (1969), who mapped one occurrence at about 47° S but did not provide documentation. The Vema specimen reported herein is undoubtedly that record. It is a small colony of 6 cm in height having only 12 corallites, but shows evidence of intratentacular budding, which is characteristic of the genus, leading to equal, three­dimensional dichotomous branching.
 Solenosmilia variabilis is one of the few scleractinian species having an almost cosmopolitan distribution, occurring at depths of 220–2165 m (Cairns 1995).

description: We construct a diffuse-interface model of two-phase solidification that quantitatively reproduces the classic free boundary problem on solid-liquid interfaces in the thin-interface limit. Convergence tests and comparisons with boundary integral simulations of eutectic growth show good accuracy for steady-state lamellae, but the results for limit cycles depend on the interface thickness through the trijunction behavior. This raises the fundamental issue of diffuse multiple-junction dynamics.

description: We have developed a dedicated front-end-electronics board for a high-pressure xenon gas time projection chamber for a neutrinoless double-beta decay search. The ionization signal is readout by detecting electroluminescence photons with SiPM's. The board readout the signal from 56~SiPM's through the DC-coupling and record the waveforms at 5 MS/s with a wide dynamic range up to 7,000 photons/200 ns. The SiPM bias voltages are provided by the board and can be adjusted for each SiPM. In order to calibrate and monitor the SiPM gain, additional auxiliary ADC measures 1 photon-equivalent dark current. The obtained performance satisfies the requirement for a neutrinoless double-beta decay search.

description: We report new consensus models estimating acute toxicity for algae, Daphnia and fish endpoints. We assembled a large collection of 3680 public unique compounds annotated by, at least, one experimental value for the given endpoint. Support Vector Machine models were internally and externally validated following the OECD principles. Reasonable predictive performances were achieved (RMSEext = 0.56–0.78) which are in line with those of state-of-the-art models. The known structural alerts are compared with analysis of the atomic contributions to these models obtained using the ISIDA/ColorAtom utility. A benchmarking against existing tools has been carried out on a set of compounds considered more representative and relevant for the chemical space of the current chemical industry. Our model scored one of the best accuracy and data coverage. Nevertheless, industrial data performances were noticeably lower than those on public data, indicating that existing models fail to meet the industrial needs. Thus, final models were updated with the inclusion of new industrial compounds, extending the applicability domain and relevance for application in an industrial context. Generated models and collected public data are made freely available.

description: The energy band attraction (EBA) caused by the non-orthogonal eigenvectors is a unique phenomenon in the non-Hermitian (NH) system. However, restricted by the required tight-binding approximation and meticulously engineered complex potentials, such effect has not been experimentally demonstrated. Here, an experimentally verifiable model is proposed based on the photonic counterpart of the all-dielectric Mie-resonator lattice in a parallel-plate transmission line. Through theoretical derivation, we directly connect the transmission spectra with eigenvalues and eigenvectors of the NH Hamiltonians. By precisely tuning the resonance loss of the Mie-resonators, the evolution of the EBA effect in two-level NH systems, from gapped bands, gapless bands to flat bands, is directly observed for the first time. Furthermore, such effect can be extended to a graphene-like two-dimensional NH system. Our works show a metamaterial approach towards NH topological photonics and offer a deeper understanding of band theory in open systems.

description: The triply heavy baryons in the standard model formed in direct $c$ and $b$ quark fragmentation are the $Ω_{ccc}$, $Ω_{ccb}$, $Ω_{cbb}$ and $Ω_{bbb}$ baryons. We calculate their fragmentation functions in leading order of perturbative QCD. The universal fragmentation probabilities fall within the range of $10^{-5}-10^{-7}$.We also evaluate their cross section at the LHC ($\sqrt{s}=14$ TeV) using next-to-leading order matrix elements for heavy quark-antiquark pair production. We present the differential cross sections as functions of the transverse momentum as well as the total cross sections. They range from a few nb to a few pb.

Straight contact lines on a soft, incompressible solid

description: The deformation of a soft substrate by a straight contact line is calculated, and the result applied to a static rivulet between two parallel contact lines. The substrate is supposed to be incompressible (Stokes like description of elasticity), and having a non-zero surface tension, that eventually differs depending on whether its surface is dry or wet. For a single straight line separating two domains with the same substrate surface tension, the ridge profile is shown to be be very close to that of Shanahan and de Gennes, but shift from the contact line of a distance equal to the elastocapillary length built upon substrate surface tension and shear modulus. As a result, the divergence near contact line disappears and is replaced by a balance of surface tensions at the contact line (Neumann equilibrium), though the profile remains nearly logarithmic. In the rivulet case, using the previous solution as a Green function allows one to calculate analytically the geometry of the distorted substrate, and in particular its slope on each side (wet and dry) of the contact lines. These two slopes are shown to be nearly proportional to the inverse of substrate surface tensions, though the respective weight of each side (wet and dry) in the final expressions is difficult to establish because of the linear nature of standard elasticity. A simple argument combining Neumann and Young equations is however provided to overcome this limitation. The result may have surprising implications for the modelling of hysteresis on systems having both plastic and elastic properties, as initiated long ago by Extrand and Kumagai.

description: Dans ce mémoire, je vais appliquer la distinction faite par Ruwen Ogien entre le préjudice et l’offense à l’enseignement de sujets sensibles en philosophie. Je commencerai par le récit d’un préjudice que j’ai vécu en tant qu’élève, à la suite d’une expérience de pensée proposée par le professeur. Cela amorcera une réflexion sur les intérêts et les dangers d’un tel outil pédagogique. Après avoir constaté les risques soulevés par les sujets sensibles, il s’agira de montrer en quoi leur enseignement est néanmoins indispensable pour que l’élève développe son autonomie et s’accomplisse en tant que sujet libre. J’aborderai ensuite certains moyens pédagogiques à notre disposition pour enseigner des sujets sensibles. Le débat apparaîtra comme l’option la plus évidente, mais aussi une des plus délicates à mettre en oeuvre. Les émois soulevés par les controverses révèleront l’impossible neutralité de l’enseignant qui devrait plutôt viser une posture d’impartialité engagée. Cela questionnera les limites imposées à la liberté d’expression qui ne sont légitimes que pour prévenir un préjudice, jamais simplement pour éviter l’offense. Enfin, la question des sujets sensibles nous amènera à la manière dont l’enseignant peut exercer sa profession de manière éthique. Il s’agira d’abord de réfléchir sur les contraintes qui accompagnent la responsabilité, conséquence du pouvoir exercé sur les élèves. La sollicitude sera présentée comme le deuxième fondement de cette éthique, indispensable pour considérer les élèves comme des sujets à part entière. Ces deux exigences fortes mettront à jour la nécessité de restaurer un idéal dans l’enseignement, sous la forme d’une tension dynamique vers des valeurs inconditionnées.

description: We present a study of the noise driven escape of an overdamped Brownian particle moving in a cubic potential profile with a metastable state. We analyze the role of the initial conditions of the particle on the enhancement of the average escape time as a function of the noise intensity for fixed and fluctuating potentials. We observe the noise enhanced stability effect for all the initial unstable states investigated. For a fixed potential we find a peculiar initial condition $x_c$ which separates the set of the initial unstable states in two regions: those which give rise to divergences from those which show nonmonotonic behavior of the average escape time. For fluctuating potential at this particular initial condition and for low noise intensity we find large fluctuations of the average escape time.

description: Ce mémoire professionnel s’intéresse aux tenues vestimentaires des élèves à l’école obligatoire, question déjà au centre des débats dans certains pays, notamment en Amérique du Nord et au Royaume Uni, mais actuellement encore peu explorée en Suisse. Plus spécifiquement, ce travail se penche sur l’article 115, al. 4 de la LEO exigeant le port d’une « tenue vestimentaire décente » par les élèves, et en particulier sur l’application qu’en fait le corps professionnel de l’école au niveau du secondaire I. Partant de là, notre étude interroge les représentations des adultes travaillant dans les établissements scolaires ainsi que leurs pratiques afin de comprendre leur posture face à la question de la décence des tenues vestimentaires des élèves. Nos données ont été recueillies au moyen de questionnaires récoltés auprès de 51 adultes travaillant dans plusieurs établissements du secondaire I. Les résultats mettent en évidence de vastes divergences concernant le rôle de l’école dans la règlementation des tenues vestimentaires, ainsi qu’une absence totale de consensus autour des critères de la décence. Comme ce concept n’est pas défini juridiquement, les professionnel.le.s des établissements scolaires appliquent la loi sans autres références que leurs propres représentations de cette notion, qui sont souvent empreintes de sexisme, classisme ou racisme. En effet, notre étude illustre que les adultes de l’école conçoivent la décence selon des paradigmes différents pour les garçons et pour les filles. Il en ressort également que les critères pour qualifier une tenue de décente impliquent beaucoup plus d’interdictions pour ces dernières. Dans les pratiques, il ressort de notre recherche que les professionnel.le.s des établissements scolaires attendent généralement des élèves qu’iels sachent distinguer une tenue décente d’une tenue indécente, alors qu’elleux-mêmes n’arrivent pas à un consensus. De plus, l’absence de recommandations dans les mesures à appliquer face aux tenues jugées indécentes donne lieu à des pratiques très hétérogènes. Pour pallier aux problèmes soulevés par notre recherche, nous préconisons notamment la mise en place d’un projet transversal destiné aux élèves autour de l’habillement ainsi qu’une meilleure formation des enseignant.e.s. en matière d’outils d’analyse sociologique et de sensibilisation à la question des inégalités sociales. Cela permettrait d’aller vers une pratique plus inclusive, plus uniforme et réellement éducative concernant la question des tenues vestimentaires.

description: Automatically extracting Protein-Protein Interactions (PPI) from biomedical literature provides additional support for precision medicine efforts. This paper proposes a novel memory network-based model (MNM) for PPI extraction, which leverages prior knowledge about protein-protein pairs with memory networks. The proposed MNM captures important context clues related to knowledge representations learned from knowledge bases. Both entity embeddings and relation embeddings of prior knowledge are effective in improving the PPI extraction model, leading to a new state-of-the-art performance on the BioCreative VI PPI dataset. The paper also shows that multiple computational layers over an external memory are superior to long short-term memory networks with the local memories.

description: A quantitative structure–activity relationship (QSAR) model was built from a dataset of 54 peptide-type compounds as SARS-CoV inhibitors. The analysis was executed to identify prominent and hidden structural features that govern anti-SARS-CoV activity. The QSAR model was derived from the genetic algorithm–multi-linear regression (GA-MLR) methodology. This resulted in the generation of a statistically robust and highly predictive model. In addition, it satisfied the OECD principles for QSAR validation. The model was validated thoroughly and fulfilled the threshold values of a battery of statistical parameters (e.g. r2 = 0.87, Q2loo = 0.82). The derived model is successful in identifying many atom-pairs as important structural features that govern the anti-SARS-CoV activity of peptide-type compounds. The newly developed model has a good balance of descriptive and statistical approaches. Consequently, the present work is useful for future modifications of peptide-type compounds for SARS-CoV and SARS-CoV-2 activity.

description: We compute the correlation functions mixing the powers of two non-commuting random matrices within the same trace. The angular part of the integration was partially known in the literature: we pursue the calculation and carry out the eigenvalue integration reducing the problem to the construction of the associated biorthogonal polynomials. The generating function of these correlations becomes then a determinant involving the recursion coefficients of the biorthogonal polynomials.

description: Phase differences and amplitude ratios at different colour photometric bands are currently being used to discriminate pulsation modes in order to facilitate mode identification of kappa-driven non-radial pulsating stars. In addition to physical inputs (e.g., mass, T_eff, etc.), these quantities depend on the non-adiabatic treatment of the atmosphere. This paper presents theoretical results concerning Delta Scuti pulsating stars. The envelope of each of these stellar structures possesses a convection zone whose development is determined by various factors. An interacting pulsation-atmosphere physical treatment is introduced which supplies two basic non-adiabatic physical quantities: the relative effective temperature variation and the phase lag phi^T, defined as the angle between effective temperature variations and radial displacement. These quantities can be used to derive the phase differences and amplitude ratios. Numerical values for these quantities depend critically on the alpha MLT parameter used to calculate the convection in the envelope. The dependence on alpha was analized and it was found that the use of colour observations may be of considerable importance in testing the MLT. Finally, examples are given of how alpha introduces uncertainties in the theoretical predictions regarding phases and amplitudes of photometric variations in Delta Scuti pulsating stars.

description: A set of 23 steroidal 1,2,4,5-tetraoxane analogues were studied using quantum-chemical method (B3LYP/6-31 G*) and multivariate analyses (PCA, HCA, KNN and SIMCA) in order to calculate the properties and correlate them with antimalarial activity (log RA) against Plasmodium falciparum clone D-6 from Sierra Leone. PCA results indicated 99.94% of the total variance and it was possible to divide the compounds into two classes: less and more active. Descriptors responsible for separating were: highest occupied molecular orbital energy (HOMO), bond length (O1-O2), Mulliken electronegativity (χ) and Bond information content (BIC0). We use HCA, KNN and SIMCA to explain relationships between molecular properties and biological activity of a training set and to predict antimalarial activity (log RA) of 13 compounds (#24-36) with unknown biological activity. We apply molecular docking simulations to identify intermolecular interactions with a selected biological target. The results obtained in multivariate analysis aided in the understanding of the activity of the new compound's design (#24-36). Thus, through chemometric analyses and docking molecular study, we propose theoretical synthetic routes for the most promising compounds 28, 30, 32 and 36 that can proceed to synthesis steps and in vitro and in vivo assays.

description: We study the radiative transitions between vector and pseudoscalar quarkonia in the light-front Hamiltonian approach, and investigate the effects of using different current component and different reference frames. In practical calculations with truncated Fock spaces, transition form factors may acquire current component dependence and frame dependence, and such dependences could serve as a measure for the Lorentz symmetry violation. We suggest using the transverse current with $m_j=0$ state of the vector meson, since this procedure employs the dominant spin components of the light-front wavefunctions and is more robust in practical calculations. We calculate the transition form factor between vector and pseudoscalar quarkonia and investigate the frame dependence with light-front wavefunctions calculated from the valence Fock sector. We suggest using frames with minimal longitudinal momentum transfer for calculations in the valence Fock sector, namely the Drell-Yan frame for the space-like region and a specific longitudinal frame for the timelike region; at $q^2=0$ these two frames give the same result.
