title: In Vitro Studies of SIV nef Function
Creators: name: Akhtar Karim, Shamim
Publisher: name: The Open University
Year: 2003

description: There is strong evidence that a functional Nef protein of human and simian immunodeficiency viruses is a critical factor in contributing to viral pathogenesis. A variety of properties have been ascribed to Nef that may contribute towards these effects. However, the exact mechanisms by which Nef functions remain unclear.
 A number of clones of SIV nef have been described which were generated after spontaneous evolution both in vivo and in vitro based upon changes relative to the wild type SIVmacJ5 virus (Rud et ah, 1994, Arnold et al, 1999, N. Almond, personal communication). Furthermore, additional clones exist which were based upon the repair mutants reported by Whatmore et al (1995) after infection of macaques with the attenuated SlVmacCS virus (Rud et al, 1994).
The aims of this study were two-fold. First, to utilise a panel of SIV Nef specific monoclonal antibodies (Arnold et al, 1999) to elucidate structural differences between wild type and attenuated SIV Nef clones and further information on the epitope recognised by the conformational dependant monoclonal antibody, KX70 (Arnold et al, 1999). Second, by utilising yeast-2-hybrid technology to investigate interactions of the SIV Nef clones with selected cellular components and relate these findings to the manner in which the virus behaves in vivo.
The results indicate that the alpha helical region around which the attenuation in SrVmacCS lies is a key component of the epitope recognised by KK70 as well as being a key region for interaction of cellular components with SIV Nef. The repair mutants reported by Whatmore et al (1995) did not regain the epitope recognised by KK70 as the amino acids evolved to a near wild type sequence. This indicates that it may be an overall structural effect that these mutations are having which is affecting antigenicity. Interestingly, one of the repair mutants (J5(EIYL)) did regain the ability to interact with the cellular components. This was lost when this repair was presented in conjunction with the R191E mutation (J5(EIYL+R>E)). Interestingly, the R191E mutation alone (J5(R>E)) caused non-specific trans-activation of the GAL4-AD. Furthermore, GX2, which harbours a 66 nucleotide deletion at the 5’ end of Nef (disrupting the binding of KK75, a monoclonal antibody that recognises a linear epitope) also caused non-specific trans-activation of the GAL4-AD. These results suggest that the mutations in GX2 and J5(R>E) may have a significant effect on the overall structure of SIV Nef.
This study describes the use of a novel technique for the fine mapping of novel antigenic epitopes using monoclonal antibodies. The structural and yeast-2-hybrid data together highlight important observations of SIV Nef which can be related to structure and function in vivo, as well as being used as a basis for future in vivo studies.

description: The interaction between a YSO stellar magnetic field and its protostellar disc can result in stellar accretional flows and outflows from the inner disc rim. Gas flows with a velocity component perpendicular to disc midplane subject particles to centrifugal acceleration away from the protostar, resulting in particles being catapulted across the face of the disc. The ejected material can produce a "dust fan", which may be dense enough to mimic the appearance of a "puffed-up" inner disc rim. We derive analytic equations for the time dependent disc toroidal field, the disc magnetic twist, the size of the stable toroidal disc region, the jet speed and the disc region of maximal jet flow speed. We show how the observed infrared variability of the pre-transition disc system LRLL~31 can be modelled by a dust ejecta fan from the inner-most regions of the disc whose height is partially dependent on the jet flow speed. The greater the jet flow speed, the higher is the potential dust fan scale height. An increase in mass accretion onto the star tends to increase the height and optical depth of the dust ejection fan, increasing the amount of 1--8~$μ$m radiation. The subsequent shadow reduces the amount of light falling on the outer disc and decreases the 8-- 40~$μ$m radiation. A decrease in the accretion rate reverses this scenario, thereby producing the observed "see-saw" infrared variability.

description: We study static configurations of dark matter coupled to a scalar field responsible for the dark energy of the Universe. The dark matter is modelled as a Fermi gas within the Thomas-Fermi approximation. The mass of the dark matter particles is a function of the scalar field. We analyze the profile of the dark matter halos in galaxies. In this case our framework is equivalent to the model of the isothermal sphere. In the presence of a scalar field, the velocity of a massive object orbiting the galaxy is not of the order of the typical velocity of the dark matter particles, as in the conventional picture. Instead, it is reduced by a factor that quantifies the dependence of the dark matter mass on the scalar field. This has implications for dark matter searches. We derive new solutions of the Einstein equations which describe compact objects composed of dark matter. Depending on the scale of the dark matter mass, the size of these objects can vary between microscopic scales and cosmological distances. We determine the mass to radius relation and discuss the similarities with conventional neutron stars and exotic astrophysical objects.

description: Cette communication présente les résultats d’une série d’essais de cisaillement direct réalisés sur le sable de Chlef renforcé par des fibres de polypropylène variant de 0, 0.2, 0.4 et 0.8%. Les essais ont été réalisés sur des échantillons de sable lâches (Dr = 15%), moyens (Dr = 50%) et denses (Dr = 85%) sous des contraintes normales de 50, 100 et 200 kPa. Les résultats des essais montrent que l’ajout des fibres de polypropylène influence d’une manière considérable sur la résistance au cisaillement du mélange sable-fibres, en effet, cette résistance augmente avec l’augmentation du pourcentage de fibres et avec l’augmentation de la contrainte normale appliquée et la densité relative. L’angle de frottement interne mobilisé augmente d’une manière significative avec l’augmentation du pourcentage de fibres. Cet angle est plus important pour la densité moyenne et forte que la densité lâche.

Traffic flow of interacting self-driven particles: rails and trails, vehicles and vesicles

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

description: One common feature of a vehicle, an ant and a kinesin motor is that they all convert chemical energy, derived from fuel or food, into mechanical energy required for their forward movement; such objects have been modelled in recent years as {\it self-driven} ``particles''. Cytoskeletal filaments, e.g., microtubules, form a ``rail'' network for intra-cellular transport of vesicular cargo by molecular motors like, for example, kinesins. Similarly, ants move along trails while vehicles move along lanes. Therefore, the traffic of vehicles and organisms as well as that of molecular motors can be modelled as systems of interacting self-driven particles; these are of current interest in non-equilibrium statistical mechanics. In this paper we point out the common features of these model systems and emphasize the crucial differences in their physical properties.

description: Les forêts du Bassin du Congo constituent un trésor essentiel pour la survie de l’humanité. Toutefois, elles font l’objet d’une mauvaise gestion du fait de la coupe intensive et très sélective d’un nombre limité d’essences. L’objectif de ce papier est de développer des panneaux de contreplaqué collés à l’état vert de nouvelles essences tropicales en vue d’élargir le potentiel exploitable que promet cette technologie pour contribuer à une gestion forestière plus durable. Les plis de bois, séchés artificiellement avant d'être collés, subissent généralement plusieurs dommages (fissures, déformations), limitant l'utilisation de ces espèces. La solution proposée est de les coller à l'état vert à l'aide d'un adhésif polyuréthane (Collano RP 2554) avant de les sécher. Nous nous sommes dirigés vers le séchage sous vide avec des cycles de séchage/humidification, pour relaxer les contraintes induites par les retraits anisotropiques. Quatre essences originales ont fait l’objet de mise en œuvre et de caractérisation normalisée. Les contreplaqués obtenus présentent des résultats en tous points satisfaisants. Les résultats les plus significatifs sont pour les essences de Bété et Dabema qui peuvent maintenant être valorisées industriellement grâce à cette technologie.

description: A large-scale three-dimensional model of Galactic extinction is presented based on the Galactic dust distribution model of Drimmel and Spergel (2001). The extinction A_V to any point within the Galactic disk can be quickly deduced using a set of three-dimensional cartesian grids. Extinctions from the model are compared to empirical extinction measures, including lines-of-sight in and near the Galactic plane using optical and NIR extinction measures; in particular we show how extinction can be derived from NIR color-magnitude diagrams in the Galactic plane to a distance of 8 kiloparsec.

description: One of the goals of gravitational-wave astronomy is to quantify the evolution of the compact binary merger rate with redshift. The redshift distribution of black hole mergers would offer considerable information about their evolutionary history, including their progenitor formation rate, the dependence of black hole formation on stellar metallicity, and the time delay distribution between formation and merger. Efforts to measure the binary redshift distribution are currently limited, however, by the detection range of existing instruments, which can individually resolve compact binary merger events only out to $z\lesssim1$. We present a novel strategy with which to measure the redshift distribution of binary black hole mergers well beyond the detection range of current instruments. By synthesizing direct detections of individually resolved mergers with \textit{indirect} searches for the stochastic gravitational-wave background due to unresolved distant sources, we can glean information about the peak redshift, $z_p$, at which the binary black hole merger rate attains its maximum, even when this redshift is beyond the detection horizon. Using data from Advanced LIGO and Virgo's first and second observing runs, we employ this strategy to place joint constraints on $z_p$ and the slope $α$ with which the binary merger rate increases at low redshifts, ruling out merger rates that grow faster than $α\gtrsim 7$ and peak beyond $z_p \gtrsim 1.5$. Looking ahead, we project that approximately one year of observation with design-sensitivity Advanced LIGO will further break remaining degeneracies, enabling a direct measurement of the peak redshift of the binary black hole merger history.

description: We calculate the four-wave mixing (FWM) in a Bose-Einstein condensate system having multiple spin wave packets that are initially overlapping in physical space, but have nonvanishing relative momentum that cause them to recede from one another. Three receding condensate atom wave packets can result in production of a fourth wave packet by the process of FWM due to atom-atom interactions. We consider cases where the four final wave packets are composed of 1, 2, 3 and 4 different internal spin components. FWM with 1- or 2-spin state wave packets is much stronger than 3- or 4-spin state FWM, wherein two of the coherent moving BEC wave packets form a polarization-grating that rotates the spin projection of the third wave into that of fourth diffracted wave (as opposed to the 1- or 2-spin state case where a regular density-grating is responsible for the diffraction). Calculations of FWM for $^{87}$Rb and $^{23}$Na condensate systems are presented.

Les éprouvettes munies de différents joints de colle ont été prélevées sur des poutres en Bois Lamellés Collé (BLC) combinées. Des essais de cisaillement par compression ont été effectués sur les éprouvettes à 12±4 % d’humidité, puis sur des éprouvettes humidifiées. L’objectif est de d’évaluer l’influence de l’humidité sur la résistance des joints de colle mixte et comprendre le mode de rupture des poutres constituées de ces joints de colle lorsqu’elles sont soumises à des efforts de flexion. Les résultats ont montré d’une part, que la résistance des joints de colle respectait les exigences structurales lorsqu’ils sont soumis à un effort de cisaillement, d’autre part on note une influence significative sur la résistance lorsque les éprouvettes sont humidifiées et une similarité au niveau des modes de rupture observés lors des essais de cisaillement et de flexion.

description: Social interaction between microbes can be described at many levels of details, ranging from the biochemistry of cell-cell interactions to the ecological dynamics of populations. Choosing the best level to model microbial communities without losing generality remains a challenge. Here we propose to model cross-feeding interactions at an intermediate level between genome-scale metabolic models of individual species and consumer-resource models of ecosystems, which is suitable to empirical data. We applied our method to three published examples of multi-strain Escherichia coli communities with increasing complexity consisting of uni-, bi-, and multi-directional cross-feeding of either substitutable metabolic byproducts or essential nutrients. The intermediate-scale model accurately described empirical data and could quantify exchange rates elusive by other means, such as the byproduct secretions, even for a complex community of 14 amino acid auxotrophs. We used the three models to study each community's limits of robustness to perturbations such as variations in resource supply, antibiotic treatments and invasion by other "cheaters" species. Our analysis provides a foundation to quantify cross-feeding interactions from experimental data, and highlights the importance of metabolic exchanges in the dynamics and stability of microbial communities.

Dans ce contexte, au sein de l'IUT de Nîmes, un bâtiment expérimental largement instrumenté a été conçu à des fins d'enseignement et de recherche. Plusieurs techniques et protocoles sont utilisés pour contrôler l'équipement et acquérir des données. L'analyse des données recueillies doit permettre de comprendre les facteurs qui contribuent à l'efficacité énergétique du bâtiment mais aussi d'identifier la performance énergétique des équipements au regard du confort des occupants. La simulation de l’occupant se concentre sur trois actions principales : le contrôle des volets, régulation de la température intérieure de consigne et la consommation d'eau chaude sanitaire (ECS). Sur quatre semaines en saison hivernale de l’année 2020, quatre scénarios d’usage du bâtiment par l'occupant sont simulés afin d'identifier leur impact sur le comportement énergétique du bâtiment. Le chauffage et le refroidissement sont assurés par une pompe à chaleur air-eau réversible, la production d'ECS est assurée par un système électro solaire. Six panneaux photovoltaïques alimentent le bâtiment. La ventilation est assurée par un système contrôlé de ventilation mécanique à double flux, couplé à un échangeur de chaleur sol-air.

description: As people move away from nutritionally rich diets, the prevalence of non-communicable diseases (NCDs) has become one of the major challenges to the present world. However, the impact of NCDs on developing nations is more pronounced than that on developed nations. Sri Lanka, a lower-middle income developing country, is currently experiencing a rising incidence of NCDs. Close association between NCDs and unhealthy dietary habits infers the importance of studying household food and nutrient consumption in order to introduce sound policy implementations. Sri Lanka lacks national level studies related to food and nutrient consumption at household levels, thus the objective of this study is to analyze demographic and socio-economic determinants of consumption for major food commodities in Sri Lanka. Data are obtained from the latest household income and expenditure survey conducted by the Sri Lankan Department of Census and Statistics. Price and expenditure elasticities for food commodities are estimated using the Quadratic Almost Ideal Demand System (QUAIDS). The zero-expenditure problem that typically exists in survey data is circumvented by employing a Tobit model. Analysis is further extended to calculate nutrient elasticities. The results of this study demonstrate the impact of price and income changes on dietary intake of households.

description: The measurement of the flux of beryllium neutrinos with the accuracy of about 10% and CNO neutrinos with the accuracy 30% will enable to find the flux of pp-neutrinos in the source with the accuracy better than 1% using the luminosity constraint. The future experiments on νe- scattering will enable to measure with very good accuracy the flux of beryllium and pp-neutrinos on the Earth. The ratio of the flux of pp-neutrinos on the Earth and in the source will enable to find with very good accuracy a mixing angle theta solar. Lithium detector has high sensitivity to CNO neutrinos and can find the contribution of CNO cycle to the energy generated in the Sun. This will be a stringent test of the theory of stellar evolution and combined with other experiments will provide a precise determination of the flux of pp-neutrinos in the source and a mixing angle theta solar. The work on the development of the technology of lithium experiment is now in progress.

description: In this work, we consider the problem of searching people in an unconstrained environment, with natural language descriptions. Specifically, we study how to systematically design an algorithm to effectively acquire descriptions from humans. An algorithm is proposed by adapting models, used for visual and language understanding, to search a person of interest (POI) in a principled way, achieving promising results without the need to re-design another complicated model. We then investigate an iterative question-answering (QA) strategy that enable robots to request additional information about the POI's appearance from the user. To this end, we introduce a greedy algorithm to rank questions in terms of their significance, and equip the algorithm with the capability to dynamically adjust the length of human-robot interaction according to model's uncertainty. Our approach is validated not only on benchmark datasets but on a mobile robot, moving in a dynamic and crowded environment.

description: L’addition de fibres conductrices à un matériau cimentaire diminue les valeurs de son impédance électrique, permettant son exploitation à des fins de monitoring, en se basant sur l’exploitation d’une relation entre les sollicitations externes (mécanique ou thermique) et variation des propriétés électriques. Dans ce contexte, des variations des propriétés électriques dues au séchage empêchent donc l’application de cette technique, à moins que ces dernières soient négligeables, ou prédictibles avec précision. Ce papier a donc pour objectif d’étudier la variation de l’impédance électrique complexe lors du séchage, pour des fréquences de mesure comprises entre 4 Hz et 1 MHz. Les mesures de retrait, perte de mase, spectre d’impédance électrique ont été réalisées sur trois mortiers avec des fractions volumiques de fibres (FVF) de carbone de 0, 0,1 et 0,5 %. Les résultats montrent qu’en absence de fibres conductrices, les parties réelles et imaginaires de l’impédance augmentent à cause de la perte d’eau. En revanche, en présence d’un réseau de fibres de carbone percolé, l’impédance réelle du matériau diminue à basses fréquences et augmente à hautes fréquences durant le séchage ; pour des plages intermédiaires de fréquence, des valeurs quasi-constantes peuvent être observées. De plus, au fur et à mesure que le matériau sèche, le comportement capacitif du matériau s’estompe et les valeurs d’impédance imaginaire tendent vers 0. Le comportement électrique se rapproche alors d’un comportement résistif idéal avec une valeur d’impédance réelle indépendante de la fréquence de mesure. Les fréquences aveugles ont été repérée pour les mortiers fibrés autour de 1 KHz et 40 KHz respectivement pour 0.1% et 0.5 % de FVF. En revanche, cette fréquence aveugle n’existait pas pour le mortier de référence. Cette plage de fréquence peut permettre, en cas de structural health monitoring à long terme, la détection des effets des charges mécaniques externes sur l’impédance, avec des effets minimes lié au séchage du mortier.

description: Most rivers in Nepal originate in the high mountain glaciers and flow into the Ganges serving as the primary source of fresh water for the whole region. However, global warming-induced changes in temperature and rainfall patterns are accelerating the rate of deglaciation, the frequency of glacial lake outburst, massive flooding, and droughts. Moreover, the climate-induced changes in Nepalese river systems, which contribute more than 70 percent of the dry season river flow to the Ganges, is significantly affecting transboundary water supply and use in Nepal, India, and Bangladesh. In this light, this study uses a hydro-economic model to determine the optimal allocation of water in Fewa Lake watershed among four competing uses - irrigation, municipal use, power generation, and recreational use. Preliminary results show considerable opportunity to increase economic efficiency, equity, and sustainability. For example, construction of additional reservoir storage capacity and better use of available rainfall and river flow data in managing existing reservoir systems can substantially improve power generation capacity, ability to control flood, and increase irrigation productivity without significantly reducing downstream flow.

description: Fast Radio Bursts (FRBs) are bright radio transients with millisecond duration at cosmological distances. Since compact dark matter/objects (COs) could act as lenses and cause split of this kind of very short duration signals, Mu$\rm{\tilde{n}}$oz et al. (2016) has proposed a novel method to probe COs with lensing of FRBs. In this Letter, we for the first time apply this method to real data and give constraints of the nature of COs with currently available FRB observations. We emphasize the information from dynamic spectra of FRBs is quite necessary for identifying any lensed signals and find no echoes in the existing data. The null search gives a constraint comparable to that from galactic wide binaries, though the methods of redshift inference from dispersion measure would impact a little. Furthermore, we make an improved forecast basing on the distributions of real data for the ongoing and upcoming telescopes. Finally, we discuss the situation where one or more lensed signals will be detected. In such a case, the parameter space of COs can be pinned down very well since the lens mass can be directly determined through the observed flux ratio and time delay between split images.

description: This paper deals with the calibration of the analogue chains of a Square Kilometre Array (SKA) phased aperture array station, using embedded element patterns (one per antenna in the array, thus accounting for the full effects of mutual coupling) or average element patterns to generate model visibilities. The array is composed of 256 log-periodic dipole array antennas. A simulator capable of generating such per-baseline model visibility correlation matrices was implemented, which allowed for a direct comparison of calibration results using StEFCal (Statistically Efficient and Fast Calibration) with both pattern types. Calibrating the array with StEFCal using simulator-generated model visibilities was successful and thus constitutes a possible routine for calibration of an SKA phase aperture array station. In addition, results indicate that there was no significant advantage in calibrating with embedded element patterns, with StEFCal successfully retrieving similar per-element coefficients with model visibilities generated with either pattern type. This can be of significant importance for mitigating computational costs for calibration, particularly for the consideration of real-time calibration strategies. Data from the AAVS-1 (Aperture Array Verification System 1) prototype station in Western Australia was used for demonstration purposes.

description: Les transferts d’humidité dans les matériaux de construction sont de grande importance à cause de leur impact sur la durabilité mais aussi sur le confort des habitants. De plus, les matériaux de construction sont généralement fortement multiphasiques et hétérogènes. Une attention particulière doit donc être portée à leur modélisation pour une meilleure prédiction du comportement énergétique des bâtiments. Dans ce travail, l’originalité est d’élaborer un modèle de transferts couplés de chaleur et d’humidité, en incluant le phénomène d’hystérésis d’adsorption et de désorption d’eau et en utilisant les microstructures réelles du matériau d’étude. Les résultats numériques démontrent que la prise en compte des hétérogénéités du matériau à travers des volumes 3D reconstruits permettait une meilleure appréhension de son comportement hygrothermique.

description: The positive relationship between institution quality and “official” income is well-documented. It is unclear, however, if this relationship holds once the “unofficial” economy is accounted for. An improvement in institutional quality tends to shift production out of the shadow and into the official sector. This can result in an increase in official income, at the expense of the shadow economy. This paper uses data from 4,954 Brazilian municipalities to explore the effects of institutional quality on formal, informal, and total income per-worker. The results indicate that an improvement in institutional quality leads to a positive change in total income per-worker. Importantly, the effect of improved institutional quality on income per-worker in the informal sector is neutral to positive, contradicting the findings of previous models. It seems that while positive institutional change does reallocate production from the shadows to the official sector, the reallocation increases overall productivity in the economy.

description: The appearance of the coronavirus (COVID-19) in late 2019 has dominated the news in the last few months as it developed into a pandemic. In many mathematics and physics classrooms, instructors are using the time series of the number of cases to show exponential growth of the infection. In this manuscript we propose a simple diffusion process as the mode of spreading infections. This model is less sophisticated than other models in the literature, but it can capture the exponential growth and it can explain it in terms of mobility (diffusion constant), population density, and probability of transmission. Students can change the parameters and determine the growth rate and predict the total number of cases as a function of time. Students are also given the opportunity to add other factors that are not considered in the simple diffusion model.

description: We present magnetotransport calculations for homogeneous two-dimensional electron systems including the Rashba spin-orbit interaction, which mixes the spin-eigenstates and leads to a modified fan-chart with crossing Landau levels. The quantum mechanical Kubo formula is evaluated by taking into account spin-conserving scatterers in an extension of the self-consistent Born approximation that considers the spin degree of freedom. The calculated conductivity exhibits besides the well-known beating in the Shubnikov-de Haas (SdH) oscillations a modulation which is due to a suppression of scattering away from the crossing points of Landau levels and does not show up in the density of states. This modulation, surviving even at elevated temperatures when the SdH oscillations are damped out, could serve to identify spin-orbit coupling in magnetotransport experiments. Our magnetotransport calculations are extended also to lateral superlattices and predictions are made with respect to 1/B periodic oscillations in dependence on carrier density and strength of the spin-orbit coupling.
