description: A systematic characterization of the composition and structure of the bacterial cell-surface proteome and its complexes can provide an invaluable tool for its comprehensive understanding. The knowledge of protein complexes composition and structure could offer new, more effective targets for a more specific and consequently effective immune response against a complex instead of a single protein. Large-scale protein-protein interaction screens are the first step towards the identification of complexes and their attribution to specific pathways. Currently, several methods exist for identifying protein interactions and protein microarrays provide the most appealing alternative to existing techniques for a high throughput screening of protein-protein interactions in vitro under reasonably straightforward conditions. In this study approximately 100 proteins of Group A Streptococcus (GAS) predicted to be secreted or surface exposed by genomic and proteomic approaches were purified in a His-tagged form and used to generate protein microarrays on nitrocellulose-coated slides. To identify protein-protein interactions each purified protein was then labeled with biotin, hybridized to the microarray and interactions were detected with Cy3-labelled streptavidin. Only reciprocal interactions, i. e. binding of the same two interactors irrespective of which of the two partners is in solid-phase or in solution, were taken as bona fide protein-protein interactions. Using this approach, we have identified 20 interactors of one of the potent toxins secreted by GAS and known as superantigens. Several of these interactors belong to the molecular chaperone or protein folding catalyst families and presumably are involved in the secretion and folding of the superantigen. In addition, a very interesting interaction was found between the superantigen and the substrate binding subunit of a well characterized ABC transporter. This finding opens a new perspective on the current understanding of how superantigens are modified by the bacterial cell in order to become major players in causing disease.

 As science becomes more and more dependent on data and software, capturing these elements of the modern scientific procedure has become critical in achieving reproducibility. Computational notebooks have emerged as an increasingly valued way of capturing not only the traditional elements of a scientific paper but also the software steps in an executable and reproducible manner. As part of the 2020 EarthCube Annual Meeting, the EarthCube office, Leadership Council, and Technical Architecture Committee experimented by issuing a call focused on notebook submissions as peer reviewed publications. The call was well received by the community: 21 Jupyter notebooks were submitted, and 12 of these were accepted for publication. As part of the 2021 call for notebooks, the idea of expanding this call to more types of “notebooks” is being discussed, with the goal of eliciting submissions from a wider group of researchers, who may be more comfortable with other notebook technologies.

description: Using our previous construction of Eisenstein-like automorphic forms we derive formulae for the perturbative and non-perturbative parts for any group and representation. The result is written in terms of the weights of the representation and the derivation is largely group theoretical. Specialising to the E_{n+1} groups relevant to type II string theory and the representation associated with node n+1 of the E_{n+1} Dynkin diagram we explicitly find the perturbative part in terms of String Theory variables, such as the string coupling g_d and volume V_n. For dimensions seven and higher we find that the perturbation theory involves only two terms. In six dimensions we construct the SO(5,5) automorphic form using the vector representation. Although these automorphic forms are generally compatible with String Theory, the one relevant to R^4 involves terms with g_d^{-6} and so is problematic. We then study a constrained SO(5,5) automorphic form, obtained by summing over null vectors, and compute its perturbative part. We find that it is consistent with String Theory and makes precise predictions for the perturbative results. We also study the unconstrained automorphic forms for E_6 in the 27 representation and E_7 in the 133 representation, giving their perturbative part and commenting on their role in String Theory.

title: Trends and determinants of the quality of outpatient malaria case-management in Kenya
Creators: name: Amboko, Beatrice Indimuli
Publisher: name: The Open University
Year: 2021

description: Background: Health workers' compliance with "test and treat" malaria case-management guidelines is not yet optimal despite improvement trends and the availability of diagnostic and therapeutic commodities. Whether these improvement trends differ by malaria endemicity, what factors influence the improvement trends, and what predicts compliance at a high level of performance without further improvements remain poorly defined.

 Methods: I conducted a secondary analysis of 11 national, cross-sectional, outpatient malaria case-management surveys undertaken in Kenya from 2010 to 2016 after cleaning, merging, linking, and restricting the datasets. Trends in compliance with four primary "test and treat" and eight secondary outcomes reflecting artemether-lumefantrine dosing, dispensing, and counselling were measured stratified by malaria endemicity. Logistic regression modelling of 31 multilevel factors associated with the 2010-2016 improvement trends in five compliance outcomes and compliance with three outcomes during the plateauing performance phase between 2014-2016 was performed.

 Results: Improvements in all four "test and treat" and three dispensing and counselling outcomes were observed in the highest malaria risk areas around Lake Victoria. In low-risk areas (central Kenya), the only outcome that improved was compliance with no antimalarial treatment for test negative patients, while compliance with malaria testing showed declining trends. Malaria endemicity and 23 health facility, health worker, and patient-level factors were associated with improvement trends, compliance during the plateauing performance phase or both periods. The only interventional factors in the 2010-2016 dataset that I found associated with improving outcomes were RDT availability and access to guidelines. However, in the 2014-2016 analysis, training and supervision with feedback were also associated with compliance in addition to the access to guidelines.

 Conclusions: Compliance with outpatient malaria "test and treat" guidelines is influenced by malaria endemicity, interventional factors including RDT availability, access to guidelines, training, and supervision with feedback and 17 non-interventional factors operating at different periods of the policy implementation.

description: We present multi-band results for GRB071010B based on \Swift, \Suzaku, and ground-based optical observations. This burst is an ideal target to evaluate the robustness of the ${\rm E^{src}_{peak}-E_{iso}}$ and ${\rm E^{src}_{peak}-E_γ}$ relations, whose studies have been in stagnation due to the lack of the combined estimation of $\rm E^{src}_{peak}$ and long term optical monitoring. The joint prompt spectral fitting using \Swift/Burst Alert Telescope and \Suzaku/Wide-band All sky Monitor data yielded the spectral peak energy as E$^{src}_{peak}$ of $86.5^{+6.4}_{-6.3}$ keV and E$_{iso}$ of $2.25^{+0.19}_{-0.16}\times10^{52}$ erg with $z=0.947$. The optical afterglow light curve is well fitted by a simple power law with temporal index $α=-0.60\pm0.02$. The lower limit of temporal break in the optical light curve is 9.8 days. Our multi-wavelength analysis reveals that GRB071010B follows ${\rm E^{src}_{peak}-E_{iso}}$ but violates the ${\rm E^{src}_{peak}-E_γ}$ and ${\rm E_{iso}-E^{src}_{peak}-t^{src}_{jet}}$ at more than the 3$σ$ level.

description: We study non-equilibrium quantum dynamics of the single-component scalar field theory in 1+1 space-time dimensions on the basis of the Kadanoff-Baym equation including the next-to-leading-order (NLO) skeleton diagrams. As an extension of the non-relativistic case, we derive relativistic kinetic entropy at the first order in the gradient expansion of the Kadanoff-Baym equations. The derived entropy satisfies the H theorem. Next we perform numerical simulations in spatially homogeneous configurations to investigate thermalization properties of the system by evaluating the system entropy. We find that at later times the kinetic entropy increases approaching the equilibrium value, although the limited time interval in the early stage invalidates the use of it.

Asymmetric impacts of near-Earth asteroids on the Moon

Publisher: name: arXiv
Year: 2009
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: Recent lunar crater studies have revealed an asymmetric distribution of rayed craters on the lunar surface. The asymmetry is related to the synchronous rotation of the Moon: there is a higher density of rayed craters on the leading hemisphere compared with the trailing hemisphere. Rayed craters represent generally the youngest impacts. The purpose of this paper is to test the hypotheses that (i) the population of Near-Earth asteroids (NEAs) is the source of the impactors that have made the rayed craters, and (ii) that impacts by this projectile population account quantitatively for the observed asymmetry. We carried out numerical simulations of the orbital evolution of a large number of test particles representing NEAs in order to determine directly their impact flux on the Moon. The simulations were done in two stages. In the first stage we obtained encounter statistics of NEAs on the Earth's activity sphere. In the second stage we calculated the direct impact flux of the encountering particles on the surface of the Moon; the latter calculations were confined within the activity sphere of the Earth. A steady-state synthetic population of NEAs was generated from a debiased orbital distribution of the known NEAs. We find that the near-Earth asteroids do have an asymmetry in their impact flux on the Moon: apex-to-antapex ratio of 1.32 +/- 0.01. However, the observed rayed crater distribution's asymmetry is significantly more pronounced: apex-to-antapex ratio of 1.65 +/- 0.16. Our results suggest the existence of an undetected population of slower (low impact velocity) projectiles, such as a population of objects nearly coorbiting with Earth; more observational study of young lunar craters is needed to secure this conclusion.

Subjects: MED/04 Patologia generale

description: Introduction: Anti-TNF-alfa therapy has been effective in the treatment of patients with refractory  psoriasis and psoriasic arthritis. However, the risk of developing autoantibodies in these patients undergoing this therapy is not clear. 
Objective: To evaluate the induction of specific autoantibodies after anti-TNFα therapy in patients with psoriasis and psoriasic arthritis and, to evaluate the influence of the use of methotrexate on the values of  autoantibodies developed during this therapy.
Patients and methods: Serum samples from 120 patients, obtained before(baseline) the introduction of anti-TNF-alpha therapy and approximately each 3-6 months during the therapy.O f these 120 patients, 113 were found negative for autoantibodies before starting anti -TNFalpha therapy, 7 were found positive for ANA. The analysis included detection of antinuclear antibodies (ANA) and anti-dsDNA antibodies (indirect immunofluorescence on Hep-2 cells and Crithidia luciliae, respectively); anti extractable nuclear antigens antibodies( ENA)(ELISA).
RESULTS: Infliximab is associated with the highest occurrence rate of ANA, anti-dsDNA, ENA with approximately 69,2%, 11,5%, 7,6% of patients treated testing positive. In comparison, only 20%, 6,6%, 2,2% of patients treated with Adalimumab, and 19%, 2,3%, 2,3% of patients treated with Etanercept were positive for ANA, Anti-dsDNA, ENA respectively. As regard the seven patients who were positive at baseline, six of them (85.7%) in addition to being remained positive during the therapy they have also increased the autoantibodies ’s titers. 
Conclusion: our study have shown that Infliximab is associated with the highest rate of autoantibodies. The concomitant treatment with methotrexate did not modify the titers of autoantibodies developed during the therapy anti-TNFalph.  The incidence of ANA, anti-dsDNA antibodies did not correlate with development of Lupus-like syndromes. The difference in the frequency of autoantibodies between psoriasis and psoriatic arthritis was not statistically significant (p = 0.867).

DARIAH (in-kind) contributions - A visual walk through activities and services

description: One of the main products of the Humanities at Scale project was a profound (re)-conceptualisation of the DARIAH in-kinds and a web-based service [2] to collect, review and display in-kind contributions, in short DARIAH contributions. [1] This paper looks at the results of the implementation phase of this new service, and particularly focuses on baseline statistics and visual analytics of the content submitted (about 300 contributions for 2017 and 2018). In general, for European Research Infrastructures, so-called in-kind contributions are a way for the members to account for their national eorts under the umbrella of the ERIC. They may represent contributions available for all ERIC members (e.g., central services executed by an institution in a member country) and/or contributions which embody, complement, or enhance the mission and strategic actions of an ERIC on the national level. DARIAH's reference model [1] on the basis of which contributions are dened, introduces two main categories: `services' and `activities'. For them a detailed metadata scheme has been devised. Submitted contributions are further subject to a detailed self-assessment and reviewing process, one part of which is dedicated to determine those contributions which are put up for the financial accountability of a member's contributions. The web-based service replaces earlier forms of template-based and data-based submission of in-kinds, and enables immediate comparison of the submissions - also by a couple of visual interfaces (map, tables). In this paper, we aim to demonstrate the main benets of the tool and zoom into three aspects. The DARIAH contribution tool relies on the tedious and comprehensive work of the National Coordinators which are in charge of the submission process. To make their often invisible work more visible is one motivation behind this paper. The submitted content as such forms an interesting empirical base for reflection on what is seen as a DARIAH contribution by the DARIAH community. This, in turn, can inform the DARIAH strategy and help to monitor the success of its actions. This is the second motivation. Submissions can still vary in form greatly, despite the formal model. They remain human generated content. Analysing the variety helps to tune the tool to user requirements, to fix bugs, and to curate the data it collects. We conclude our paper with reflections on the future use of the tool and its connection to other DARIAH strategic actions, as designed in the Strategic Action Plan II.

description: This doctoral dissertation aims to establish fiber-optic technologies overcoming the limiting issues of data communications in indoor environments. Specific applications are broadband mobile distribution in different in-building scenarios and high-speed digital transmission over short-range wired optical systems. Two key enabling technologies are considered: Radio over Fiber (RoF) techniques over standard silica fibers for distributed antenna systems (DAS) and plastic optical fibers (POFs) for short-range communications. Hence, the objectives and achievements of this thesis are related to the application of RoF and POF technologies in different in-building scenarios. On one hand, a theoretical and experimental analysis combined with demonstration activities has been performed on cost-effective RoF systems. An extensive modeling on modal noise impact both on linear and non-linear characteristics of RoF link over silica multimode fiber has been performed to achieve link design rules for an optimum choice of the transmitter, receiver and launching technique. A successful transmission of Long Term Evolution (LTE) mobile signals on the resulting optimized RoF system over silica multimode fiber employing a Fabry-Perot LD, central launch technique and a photodiode with a built-in ball lens was demonstrated up to 525m with performances well compliant with standard requirements. On the other hand, digital signal processing techniques to overcome the bandwidth limitation of POF have been investigated. An uncoded net bit-rate of 5.15Gbit/s was obtained on a 50m long POF link employing an eye-safe transmitter, a silicon photodiode, and DMT modulation with bit and power loading algorithm. With the insertion of 3x2N quadrature amplitude modulation constellation formats, an uncoded net-bit-rate of 5.4Gbit/s was obtained on a 50 m long POF link employing an eye-safe transmitter and a silicon avalanche photodiode. Moreover, simultaneous transmission of baseband 2Gbit/s with DMT and 200Mbit/s with an ultra-wideband radio signal has been validated over a 50m long POF link.
Hydroelastic impacts of deformable wedges

Subjects: ING-IND/14 Progettazione meccanica e costruzione di macchine

description: This work investigates the slamming phenomenon experienced during the water entry of deformable bodies. Wedges are chosen as reference geometry due to their similarity to a generic hull section. Hull slamming is a phenomenon occurring when a ship re-enters the water after having been partially or completely lifted out the water. 
While the analysis of rigid structures entering the water has been extensively studied in the past and there are analytical solutions capable of correctly predicting the hydrodynamic pressure distribution and the overall impact dynamics, the effect of the structural deformation on the structural force is still a challenging problem to be solved. In fact, in case of water impact of deformable bodies, the dynamic deflection could interact with the fluid flow, changing the hydrodynamic load.
This work investigates the hull-slamming problem by experiments and numerical simulations of the water entry of elastic wedges impacting on an initially calm surface. The effect of asymmetry due to horizontal velocity component or initial tilt angle on the impact dynamics is also studied. The objective of this work is to determine an accurate model to predict the overall dynamics of the wedge and its deformations. 
More than 1200 experiments were conducted by varying wedge structural stiffness, deadrise angle, impact velocity and mass. On interest are the overall impact dynamics and the local structural deformation of the panels composing the wedge. Alongside with the experimental analysis, numerical simulations based on a coupled Smoothed Particle Hydrodynamics (SPH) and FEM method are developed. 
The experimental results provide evidence of the mutual interaction between hydrodynamic load and structural deformation. It is found a simple criterion for the onset of fluid structure interaction (FSI), giving reliable information on the cases where FSI should been taken into account.

description: We give an overview of some conceptual difficulties, sometimes called paradoxes, that have puzzled for years the physical interpetation of classical canonical gravity and, by extension, the canonical formulation of generally covariant theories. We identify these difficulties as stemming form some terminological misunderstandings as to what is meant by "gauge invariance", or what is understood classically by a "physical state". We make a thorough analysis of the issue and show that all purported paradoxes disappear when the right terminology is in place. Since this issue is connected with the search of observables - gauge invariant quantities - for these theories, we formally show that time evolving observables can be constructed for every observer. This construction relies on the fixation of the gauge freedom of diffeomorphism invariance by means of a scalar coordinatization. We stress the condition that the coordinatization must be made with scalars. As an example of our method for obtaining observables we discuss the case of the massive particle in AdS spacetime.

description: The main objective of this research was to evaluate the spatial distribution of the thermal variables, acoustics and lighting in climate controlled compost dairy barn. The experiment was conducted in October 2017, in a farm located in the west of Minas Gerais state, Brazil. For the study, the interior of the animal facility was divided into 120 meshes equidistant points, in which air temperature (tdb), relative humidity (RH), noise, illuminance, and air speed (Vair) were manually collected. The technique of geostatistics was used to evaluate the distribution and spatial dependence of variables. Spatial distribution maps showed the occurrence of high variability of attributes and content within the animal facility. Thermal environment variables showed alert situations throughout practically the entire facility. The noise and luminance levels were within the recommended values.

 Abstract: Brazil is the fifth largest country in the world, a country that has great ecological and biological diversity within its territory. In order for these natural resources to be sustainably managed, it is essential to adequately monitor the country’s social and environmental conditions — which is a major challenge given the country’s territorial extent and the difficulty of accessing some of its protected areas. Using technologies that make it possible to assess the social and environmental situation of a region without having to do field work can help to provide valuable information to promote initiatives for sustainable development and biodiversity conservation on the national territory. This work uses machine learning methods for the analysis of satellite images with the goal of predicting environmental, social, and economic indicators. The neural network model developed was trained and applied in four estates of the brazilian northwest, focusing on the Caatinga biome. The results were compiled and presented on a web platform in the form of interactive maps to make data accessible as well as facilitate comparison and understanding the indicators predicted by the model.

Focusing on theories with a (2,2) locus, we examine the linear model parameter space and the dependence of genus zero half-twisted correlators on these parameters. We show that in a class of theories the correlators and parameters separate into A and B types, present techniques to compute the dependence, and apply these to some examples. These results should bear on the mathematics of (0,2) mirror symmetry and the physics of the moduli space and Yukawa couplings in heterotic compactifications.

description: In type IIB Fibre Inflation models the inflaton is a Kaehler modulus which is kinetically coupled to the corresponding axion. In this setup the curvature of the field space induces tachyonic isocurvature perturbations normal to the background inflationary trajectory. However we argue that the associated instability is unphysical since it is due to the use of ill-defined entropy variables. In fact, upon using the correct relative entropy perturbation, we show that in Fibre Inflation axionic isocurvature perturbations decay during inflation and the dynamics is essentially single-field.

description: GRB satellites are relatively inefficient detectors of dim hard bursts because they trigger on photon counts, which are number-biased against hard photons. Therefore, for example, given two bursts of identical peak luminosity near the detection threshold, a dim soft burst will be preferentially detected over a dim hard burst. This detector bias can create or skew an apparent correlation where increasingly hard GRBs appear increasingly bright. Although such correlations may be obfuscated by a middle step where GRBs need to be bright enough to have their actual redshifts determined, it is found that the bias is generally pervasive. This result is derived here through simulations convolving a wide variety of possible GRB brightnesses and spectra with the BATSE Large Area Detectors (LAD) detection thresholds. The presented analyses indicate that the rest-frame $νF_ν$ spectrum peak energy of long-duration GRBs, $\epi$, is not a good cosmological standard candle without significant corrections for selection effects. Therefore, the appearance of $\epi$ in seeming correlations such as the Amati ($E_{iso}-\epi$), Ghirlanda ($E_γ-\epi$), and $L_{iso}-\epi$ relations is statistically real but strongly influenced by so far uncalibrated GRB detector thresholds.

description: The amplitude for the 4-simplex in a spin foam model for quantum gravity is defined using a graphical calculus for the unitary representations of the Lorentz group. The asymptotics of this amplitude are studied in the limit when the representation parameters are large, for various cases of boundary data. It is shown that for boundary data corresponding to a Lorentzian simplex, the asymptotic formula has two terms, with phase plus or minus the Lorentzian signature Regge action for the 4-simplex geometry, multiplied by an Immirzi parameter. Other cases of boundary data are also considered, including a surprising contribution from Euclidean signature metrics.

description: New concepts on porosity appraisal in ancient and modern construction materials. The role of Fractal Geometry on porosity characterization and transport phenomena.

This work studied the potential of Fractal Geometry to the characterization of porous materials. Besides the descriptive aspects of the pore size distribution, the fractal dimensions have led to the development of rational relations for the prediction of permeability coefficients to fluid and heat transfer.
The research considered natural materials used in historical buildings (rock and earth) as well as currently employed materials as hydraulic cement and technologically advanced materials such as silicon carbide or YSZ ceramics. The experimental results of porosity derived from the techniques of mercury intrusion and from the image analysis. Data elaboration was carried out according to established procedures of Fractal Geometry. It was found that certain classes of materials are clearly fractal and respond to simple patterns such as Sierpinski and Menger models. In several cases, however, the fractal character is not recognised because the microstructure of the material is based on different phases at different dimensional scales, and in consequence the “fractal dimensions” calculated from porosimetric data do not come within the standard range (less than 3).
Using different type and numbers of fractal units is possible, however, to obtain “virtual” microstructures that have the fraction of voids and pore size distribution equivalent with the experimental ones for almost any material. Thus it was possible to take the expressions for the permeability and the thermal conduction which does not require empirical “constants”, these expressions have also provided values that are generally in agreement with the experimental available data. 
More problematic has been the fractal discussion of the geometry of the rupture of the material subjected to mechanical stress both external and internal applied. The results achieved on these issues are qualitative and prone to future studies.

description: We present an investigation of game-like simulations for physics teaching. We report on the effectiveness of the interactive simulation "Real Time Relativity" for learning special relativity. We argue that the simulation not only enhances traditional learning, but also enables new types of learning that challenge the traditional curriculum. The lessons drawn from this work are being applied to the development of a simulation for enhancing the learning of quantum mechanics.
Precessing ball solitons in kinetics of a spin-flop phase transition

description: The fundamentals of precessing ball solitons (PBS), arising as a result of the energy fluctuations during spin-flop phase transition induced by a magnetic field in antiferromagnets with uniaxial anisotropy, are presented. The PBS conditions exist within a wide range of amplitudes and energies, including negative energies relative to an initial condition. For each value of the magnetic field, there exists a precession frequency for which a curve of PBS energy passes through a zero value (bifurcation point), and hence, in the vicinity of this point the PBS originate with the highest probability. The characteristics of PBS, including the time dependences of configuration, energy, and precession frequency, are considered. As a result of dissipation, the PBS transform into the macroscopic domains of a new phase.

description: In this article, we study the outer automorphism group of a group G decomposed as a finite graph of group with finite edge groups and finitely generated vertex groups with at most one end. We show that Out(G) is essentially obtained by taking extensions of relative automorphism groups of vertex groups, groups of Dehn twists and groups of automorphisms of free products. We apply this description and obtain a criterion for Out(G) to be finitely presented, as well as a necessary and sufficient condition for Out(G) to be finite. Consequences for hyperbolic groups are discussed.

description: We investigate the caesium concentrations in soils in mountain areas near Gori nuclear power plant in Korea, focusing on the measurement limits to the 134Cs. In order to lower the minimum detectable amount (MDA) of activity for the 134Cs, we have used the ammonium molybdophosphase (AMP) precipitation method to get rid of the 40K existing in natural radioactivity, which reduces the MDA activity about ten times smaller than those without the AMP precipitation method. The MDA results for the 134Cs were found to be in the range between 0.015 and 0.044 Bq/kg-dry weight. In order to diminish the background, we also have measured a part of the soil samples in Yangyang, a small town in the east coast of Korea. However, it turns out that in order to detect the 134Cs in the samples the MDA should be reduced to the level of mBq/kg-dry weight.

description: Most previous contributions to BSDEs, and the related theories of nonlinear expectation and dynamic risk measures, have been in the framework of continuous time diffusions or jump diffusions. Using solutions of BSDEs on spaces related to finite state, continuous time Markov chains, we develop a theory of nonlinear expectations in the spirit of [Dynamically consistent nonlinear evaluations and expectations (2005) Shandong Univ.]. We prove basic properties of these expectations and show their applications to dynamic risk measures on such spaces. In particular, we prove comparison theorems for scalar and vector valued solutions to BSDEs, and discuss arbitrage and risk measures in the scalar case.

description: Using the MSX mid-infrared observation, we reveal a 100 pc-scale superbubble surrounding the giant HII region NGC3603. We suggest that the diffuse surrounding infrared emission in bands A, C, and D is dominated by that of PAH and the emission in band E is dominated by that of dust grains. The fitted dust temperature is consistent with the heating by the central cluster's UV photons. The derived gas-to-dust mass ratio for the bubble shell is of order 10^2.
