description: Over 300 species of naturally occurring-organoarsenicals have been identified with the development of modern analytical techniques. Why there so many environmental organoarsenicals exist is a real enigma. Are they protective or harmful? Or are they simply by-products of existing pathways for non-arsenical compounds? Fundamental unanswered questions exist about their occurrence, prevalence and fate in the environment, metabolisms, toxicology and biological functions. This review focuses on possible answers. As a beginning, we classified them into two categories: water-soluble and lipid-soluble organoarsenicals (arsenolipids). Continual improvements in analytical techniques will lead to identification of additional organoarsenicals. In this review, we enumerate identified environmental organoarsenicals and speculate about their pathways of synthesis and degradation based on structural data and previous studies. Organoarsenicals are frequently considered to be nontoxic, yet trivalent methylarsenicals, synthetic aromatic arsenicals and some pentavalent arsenic-containing compounds have been shown to be highly toxic. The biological functions of some organoarsenicals have been defined. For example, arsenobetaine acts as an osmolyte, and membrane arsenolipids have a phosphate-sparing role under phosphate-limited conditions. However, the toxicological properties and biological functions of most organoarsenicals are largely unknown. The objective of this review is to summarize the toxicological and physiological properties and to provide novel insights into future studies.

description: The effects of nonlocal and reflecting connectivity are investigated in coupled Leaky Integrate-and-Fire (LIF) elements, which assimilate the exchange of electrical signals between neurons. Earlier investigations have demonstrated that non-local and hierarchical network connectivity often induces complex synchronization patterns and chimera states in systems of coupled oscillators. In the LIF system we show that if the elements are non-locally linked with positive diffusive coupling in a ring architecture the system splits into a number of alternating domains. Half of these domains contain elements, whose potential stays near the threshold, while they are interrupted by active domains, where the elements perform regular LIF oscillations. The active domains move around the ring with constant velocity, depending on the system parameters. The idea of introducing reflecting non-local coupling in LIF networks originates from signal exchange between neurons residing in the two hemispheres in the brain. We show evidence that this connectivity induces novel complex spatial and temporal structures: for relatively extensive ranges of parameter values the system splits in two coexisting domains, one domain where all elements stay near-threshold and one where incoherent states develop with multileveled mean phase velocity distribution.

description: Introduction: Ulcerative colitis is a chronic inflammatory condition, and continuous inflammatory stimulus may lead to barrier dysfunction. The goal of this study was to assess barrier proteomic expression by a red algae-derived multi-mineral intervention in the absence or presence of pro-inflammatory insult. Methods: Human colon organoids were maintained in a control culture medium alone or exposed to lipopolysaccharide with a combination of three pro-inflammatory cytokines [tumor necrosis factor-α, interleukin-1β and interferon-γ (LPS-cytokines)] to mimic the environment in the inflamed colon. Untreated organoids and those exposed to LPS-cytokines were concomitantly treated for 14 days with a multi-mineral product (Aquamin®) that has previously been shown to improve barrier structure/function. The colon organoids were subjected to proteomic analysis to obtain a broad view of the protein changes induced by the two interventions alone and in combination. In parallel, confocal fluorescence microscopy, tissue cohesion and transepithelial electrical resistance (TEER) measurements were used to assess barrier structure/function. Results: The LPS-cytokine mix altered the expression of multiple proteins that influence innate immunity and promote inflammation. Several of these were significantly decreased with Aquamin® alone but only a modest decrease in a subset of these proteins was detected by Aquamin® in the presence of LPS-cytokines. Among these, a subset of inflammation-related proteins including fibrinogen-β and -γ chains (FGB and FGG), phospholipase A2 (PLA2G2A) and SPARC was significantly downregulated in the presence of Aquamin® (alone and in combination with LPS-cytokines); another subset of proteins with anti-inflammatory, antioxidant or anti-microbial activity was upregulated by Aquamin® treatment. When provided alone, Aquamin® strongly upregulated proteins that contribute to barrier formation and tissue strength. Concomitant treatment with LPS-cytokines did not inhibit barrier formation in response to Aquamin®. Confocal microscopy also displayed increased expression of desmoglein-2 (DSG2) and cadherin-17 (CDH17) with Aquamin®, either alone or in the presence of the pro-inflammatory stimulus. Increased cohesion and TEER with Aquamin® (alone or in the presence of LPS-cytokines) indicates improved barrier function. Conclusion: Taken together, these findings suggest that multi-mineral intervention (Aquamin®) may provide a novel approach to combating inflammation in the colon by improving barrier structure/function as well as by directly altering the expression of certain pro-inflammatory proteins.

description: Multimodal freight transport can facilitate the economic development of Operators. The Study shows particularly in fright transportation, there is developing the single mode of transport in to multimodal operation system, the characteristics of multimodal travel today in Ethiopia and assesses its future potential in Railway Corporation, the factors required to implement the multimodal operating system and make Railway will be competitive rather than shipping line. Multimodal transport requires new organizational and financial arrangements between all actors involved. Transporting freight plays a major role in the country and Ethiopian railway will start to work in the route of Addis Ababa-Djibouti in a single mode of transport. this type of transport is not sufficient to return the loan of railway in short period of time and in the sake of increasing socio- economic benefit. In this study by interviewing the groups of professional from Governmental agencies and private sector the information which is necessary for this paper is collected and the required data for this particular investigation purpose is taking from concerned sectors especially ESLSE . The previous research which is related to this title is used as a base for the theoretical and empirical framework of the study. Additionally, computerized search strategy was selected. Finally implementing multimodal operation requires solving the transportation cost, transportation time, transportation capacity constraints, and transportation allocation problem and also transporting in multimodal makes to saving 62.2USD/ton or transporting in unimodal is 1.24times that of multimodal cost and Operating Multimodal transport is 7.07 times greater profit than operating single mode of transport. Therefore By Considering enough performance of railway and its profitability implement Operating Multimodal transport is essential. Hence Ethiopian Railway use multimodal operator for their better economic efficiency and social effectiveness,

description: We analyse the classical and quantum dynamics of a Bianchi I model in the presence of a small negative cosmological constant characterizing its evolution in term of the dust-time dualism. We demonstrate that in a canonical metric approach, the cosmological singularity is removed in correspondence to a positive defined value of the dust energy density. Furthermore, the quantum Big-Bounce is connected to the Universe turning point via a well-defined semiclassical limit. Then we can reliably infer that the proposed scenario is compatible with a cyclical Universe picture. We also show how, when the contribution of the dust energy density is sufficiently high, the proposed scenario can be extended to the Bianchi IX cosmology and therefore how it can be regarded as a paradigm for the generic cosmological model. Finally, we investigate the origin of the observed cut-off on the cosmological dynamics, demonstrating how the Big-Bounce evolution can be mimicked by the same semiclassical scenario, where the negative cosmological constant is replaced via a polymer discretization of the Universe volume. A direct proportionality law between such two parameters is then established.

description: The blood flow model maintains the steady state solutions, in which the flux gradients are non-zero but exactly balanced by the source term. In this paper, we design high order finite difference weighted non-oscillatory (WENO) schemes to this model with such well-balanced property and at the same time keeping genuine high order accuracy. Rigorous theoretical analysis as well as extensive numerical results all indicate that the resulting schemes verify high order accuracy, maintain the well-balanced property, and keep good resolution for smooth and discontinuous solutions.

description: We report the outcome of multifrequency radio observations of a double-double radio source J1706+4340 carried out with the Very Large Array and Giant Metrewave Radio Telescope. After supplementing our own data with those available in the literature, we collected a considerable set of radio measurements covering the range from 74 to 8460 MHz. This has enabled us to perform a comprehensive review of physical properties of the source and its dynamical evolution analysis. In particular, we found that, while the age of the large-scale outer lobes is in the range 260-300 Myr, the renewal of the jet activity, which is directly responsible for the double-double structure, took place only about 12 Myr ago after about 27-Myr long period of quiescence. Another important property of J1706+4340 we found is that the injection spectral indices and the jet powers for the inner and the outer doubles are very similar. This implies that it is the spin of the supermassive black hole rather than e.g. an instability of the accretion disc that is likely responsible for the jet production and its properties.

description: We investigate the integrability conditions of a class of shear-free perfect-fluid cosmological models within the framework of anisotropic fluid sources, applying our results to f(R) dark energy models. Generalising earlier general relativistic results for time-like geodesics, we extend the potential and acceleration terms of the quasi-Newtonian formulation of integrable dust cosmological models about a linearized Friedmann-Lemaitre-Robertson-Walker background and derive the equations that describe their dynamical evolutions. We show that in general, models with an anisotropic fluid source are not consistent, but because of the particular form the anisotropic stress takes in f(R) gravity, the general integrability conditions, in this case, are satisfied.

description: Pregnancy can exacerbate or prompt the onset of stress-related disorders, such as post-traumatic stress disorder (PTSD). PTSD is associated with heightened stress responsivity and emotional dysregulation, as well as increased risk of chronic disorders and mortality. Further, maternal PTSD is associated with gestational epigenetic age acceleration in newborns, implicating the prenatal period as a developmental time period for the transmission of effects across generations. Here, we evaluated the associations between PTSD symptoms, maternal epigenetic age acceleration, and infant gestational epigenetic age acceleration in 89 maternal-neonatal dyads. Trauma-related experiences and PTSD symptoms in mothers were assessed during the third trimester of pregnancy. The MethylationEPIC array was used to generate DNA methylation data from maternal and neonatal saliva samples collected within 24 h of infant birth. Maternal epigenetic age acceleration was calculated using Horvath’s multi-tissue clock, PhenoAge and GrimAge. Gestational epigenetic age was estimated using the Haftorn clock. Maternal cumulative past-year stress (GrimAge: p = 3.23e-04, PhenoAge: p = 9.92e-03), PTSD symptoms (GrimAge: p = 0.019), and difficulties in emotion regulation (GrimAge: p = 0.028) were associated with accelerated epigenetic age in mothers. Maternal PTSD symptoms were associated with lower gestational epigenetic age acceleration in neonates (p = 0.032). Overall, our results suggest that maternal cumulative past-year stress exposure and trauma-related symptoms may increase the risk for age-related problems in mothers and developmental problems in their newborns.

description: We report on the first deep optical observations of two $γ$-ray pulsars, both among the very first discovered by the {\em Fermi} Gamma-ray Space Telescope. The two pulsars are the radio-loud PSR\, J1907+0602 in the TeV pulsar wind nebula (PWN) MGRO\, J1908+06 and the radio-quiet PSR\, J1809$-$2332 in the "Taz" radio/X-ray PWN. These pulsars are relatively young and energetic and have been both detected in the X-rays by \xmm, which makes them viable targets for optical observations. We observed the pulsar fields in the B and V bands with the Very Large Telescope (VLT) in June/July 2015 to search for their optical counterparts. Neither of the two pulsars has been detected down to $3σ$ limiting magnitudes of $m_{\rm v} \sim 26.9$ and $m_{\rm v} \sim 27.6$ for PSR\, J1907+0602 and PSR\, J1809$-$2332, respectively. We discuss these results in the framework of the multi-wavelength emission properties of pulsars.

Green's function representation of spin pumping effect
Creators: name: Tatara, Gen
Publisher: name: arXiv
Year: 2016
Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: In this study, current pumping by an external potential is studied on the basis of the Keldysh Green's function method, and a pumping formula written in terms of retarded and advanced Green's functions is obtained. It is shown that pumping is essentially driven by a change of particle distribution before and after an external perturbation. The formula is used to study the spin pumping effect in the case of strong sd exchange interaction, and the driving field is identified to be the spin gauge field. At the lowest order in the precession frequency of magnetization, the spin gauge field works as a constant potential, and the system is shown to reduce to a static problem of spin current generation by a time-independent potential with off-diagonal spin components.
Track Surveying and Speed Optimization (Case Study Addis Ababa – Adama Line)
Creators: name: Fayera, Mosisa
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: Speed Optimization is a means of improving the geometric alignment, infrastructure and construction materials and structure performance during the working cycles under some manufacturing, operational and failure conditions as well as cost limitations. The new Ethiopian national railway network design speed is about 120Km/h which is too low when compared with some developed countries rail speed. Construction of new high speed line needs huge investment that may not be viable for a developing country like Ethiopia and optimization of existing line using different techniques is the available option. The major anticipated problems/demand behind for high speed for the country national rail network and Addis Ababa – Adama line in particular are for that it is Competitive with toll road of same speed, located along the development axis area of Ethiopian economy, located along country's industrial zone highly polluted by industry emission, national image building, attracting investor and delay of freight at sea port. Optimization of speed were done by enquiring and analyzing existing track geometry and track super structures, construction materials and other speed related parameters to identify restrictive sections and the maximum allowable speed of the line. Geometric analysis and design were done by Bentley Inrail software in the optimization process and finite element methods were used for analyzing of track component response under optimized speed. From the analysis result, the existing track construction materials and infrastructures are within recommendable limit for introducing high speed. The geometry of the track is allowable for speed up to 130km/h by modifying cant of sharp horizontal curves. Two optimization techniques were identified for the study. The first optimization technique is introducing tilting coach and the second is upgrading existing geometric alignment. On the existing track, 160km/h speed can be operated by introducing tilting coach without upgrading the track alignment. It is possible to achieve 16okm/h for conventional train by upgrading sharp horizontal curves less than 1325m. By combination of both techniques 205km/h speed can be achieved, but due to vertical curve limitation speed more than 170km/h is not viable on the line. By all optimization techniques, the recommendable level of optimization percentage is 33%. Introducing tilt coach technology is recommendable technology as it is easy for application and economically feasible option. Since the entire Ethiopian national rail network are similar, the work done for Addis Ababa – Adama line can be projected for other routes to increase consistency system throughout the country.

description: The Dirac equation for an electron in a finite dipole potential has been studied within the method of linear combination of atomic orbitals (LCAO). The Coulomb potential of the nuclei that compose a dipole is regularized, by considering the finite nuclear size. It is shown that if the dipole momentum reaches a certain critical value, the novel type of supercriticality occurs; namely, the wave function of the highest occupied electron bound state changes its localization from the negatively charged nucleus to the positively charged one. This phenomenon can be interpreted as a spontaneous creation of an electron-positron pair in vacuum, with each of the created particles being in the bound state with the corresponding nucleus and partially screening it.

description: Die Motivationen von Lernenden und ihren Lehrkräften spielen eine bedeutsame Rolle für Lehr-Lern-Prozesse und den Lernerfolg der Lernenden, da sie die Entscheidungen und das Verhalten der Lernenden und Lehrkräfte im Unterricht prägen. Obwohl nach dem Erwartungs-Wert-Modell und der Theorie dimensionaler Vergleiche insbesondere die Unterschiede in der Motivation innerhalb einer Person zwischen verschiedenen Bereichen dabei entscheidend sein sollen, wurden diese bisher vergleichsweise wenig beachtet. Deshalb wurde in der vorliegenden Dissertation diese intraindividuelle Heterogenität in den Motivationen von sowohl Lernenden als auch Lehrkräften in drei empirischen Studien untersucht. Die erste Studie analysierte dazu fachübergreifende intraindividuelle Differenzen der Lernenden bezüglich ihrer Fähigkeiten und subjektiven Wichtigkeit der Fächer Mathematik und Lesen, wobei sowohl Selbsturteile der Lernenden als auch Urteile ihrer Grundschullehrkräfte berücksichtigt wurden. Zwei weitere Studien betrachteten die intraindividuelle Heterogenität in der Motivation von Lehrkräften zwischen verschiedenen Lernenden einer Lerngruppe (d.h. Kompetenzüberzeugungen und Unterrichtsenthusiasmus bezüglich des Unterrichtens der individuellen Lernenden). Dabei wurden insbesondere Zusammenhänge der lernendenspezifischen Motivationen der Lehrkraft mit interindividuellen Unterschieden in den Leistungen und Motivationen zwischen den Lernenden und dem Unterrichtsverhalten der Lehrkraft gegenüber den individuellen Lernenden untersucht. Die Ergebnisse verdeutlichen, dass sowohl in der Motivation der Lernenden als auch der Lehrkräfte motivationale Unterschiede innerhalb von Personen vorliegen können. Es zeigten sich Zusammenhänge dieser intraindividuellen Heterogenität mit Eigenschaften der individuellen Lernenden und dem Lehrverhalten sowie darüber hinaus auch positive Assoziationen zwischen den Wahrnehmungen von Lehrkräften und Lernenden. Die Dissertation unterstreicht somit die Bedeutung der Berücksichtigung von motivationaler Heterogenität innerhalb von Personen für ein besseres Verständnis von motivationalen Prozessen im Lehr-Lern-Kontext.

description: To effectively solve the problem of urban transportation, especially that of the downtown area, the government of Ethiopia has planned and constructed light railway transit in the city of Addis Ababa. The AALRT railway tracks basically consists a flat framework made up of rails and sleepers which is supported on ballast. The ballast rest on a sub ballast layer which form the transition layer to the formation. The significance of this research is to construct Phase-II AALRT project plan more reliable, efficient and esthetically attractive then the first phase AALRT project. This research would assess and evaluate lesson learned from first phase AALRT project. It focuses on external interactions that occur between the various components of a track structures and its supporting systems, integration with landscape, highway transportations and infra-structures. Besides, safety, future expansion, aesthetics and drainage system, wastage of materials and human power, the technology, knowledge and skill gained during construction and operation track structures. The research were held through site investigations, desk studies and questionnaires response. The primary data for research gained from desk study through review detail design documents and literature from the Ethiopian railway corporation. The questionnaires are on the findings of the research analyzed using simple statistical approaches, Likert"s scale and standard error deviation. Within this study it is possible to conclude assessment and evaluation the constructed AALRT project track structures. The research identifying that providing light railway transit for resident of city has the effective solution for the immediate transportation problem. Besides, there is also lack of integration between the constructed railroad with existing buildings, pipes, wires and transportation situation. The commercial activities decrease due to cause of the laid railroad separate the city in two sides. The constructed AALRT project would not consider safety, future expansion and urban aesthetics. It also shows that there was wastage of properties, materials,

description: We examined the phenotypical intra- and inter-populational variation of Laudakia stellio, one of the most-studied agamids, which is widely distributed in Anatolia in order to reveal the qualitative and quantitative aspects of the morphological differences among populations. We used for the quantification of colouration of different body parts colour palettes with the RGB (Red-Green-Blue) colour scale and prepared colour histograms. The populations were compared with Principal Component Analyses (PCA). We found that the 1st dorsal pattern which is the first of 4-5 star-like pattern throughout the vertebral line, provides information about the sex of the individual and the geographic location of the population. PCA graphs revealed the colouration differences between localities of dorsal, lateral, ventral head and dorsal body regions. A phylogenetic analysis of the mitochondrial ND4 marker revealed four different lineages, namely Hatay, Adana-Mersin-Konya, Burdur-Denizli and Manisa-İzmir-Çanakkale. Noting the need for new studies with different genes, our results show that colouration and quantitative morphology are supported by phylogeny in L. stellio populations, especially in terms of subspeciation.
Planar Zeros in Gauge Theories and Gravity

description: Planar zeros are studied in the context of the five-point scattering amplitude for gauge bosons and gravitons. In the case of gauge theories, it is found that planar zeros are determined by an algebraic curve in the projective plane spanned by the three stereographic coordinates labelling the direction of the outgoing momenta. This curve depends on the values of six independent color structures. Considering the gauge group SU(N) with N=2,3,5 and fixed color indices, the class of curves obtained gets broader by increasing the rank of the group. For the five-graviton scattering, on the other hand, we show that the amplitude vanishes whenever the process is planar, without imposing further kinematic conditions. A rationale for this result is provided using color-kinematics duality.

description: The aim of this paper is to study a class of nonlocal fractional Laplacian equations depending on two real parameters. More precisely, by using an appropriate analytical context on fractional Sobolev spaces due to Servadei and Valdinoci, we establish the existence of three weak solutions for nonlocal fractional problems exploiting an abstract critical point result for smooth functionals. We emphasize that the dependence of the underlying equation from one of the real parameter is not necessarily of affine type.

description: A theoretical study on how synchronization and resonance-like phenomena in superparamagnetic tunnel junctions can be driven by spin-transfer torques is presented. We examine the magnetization of a superparamagnetic free layer that reverses randomly between two well-defined orientations due to thermal fluctuations, acting as a stochastic oscillator. When subject to an external ac forcing this system can present stochastic resonance and noise-enhanced synchronization. We focus on the roles of the mutually perpendicular damping-like and field-like torques, showing that the response of the system is very different at low and high-frequencies. We also demonstrate that the field-like torque can increase the efficiency of the current-driven forcing, specially at sub-threshold electric currents. These results can be useful for possible low-power, more energy efficient, applications.

Jet formation in solar atmosphere due to magnetic reconnection

description: Using numerical simulations, we show that jets with features of type II spicules and cold coronal jets corresponding to temperatures $10^{4}$ K can be formed due to magnetic reconnection in a scenario in presence of magnetic resistivity. For this we model the low chromosphere-corona region using the C7 equilibrium solar atmosphere model and assuming Resistive MHD rules the dynamics of the plasma. The magnetic filed configurations we analyze correspond to two neighboring loops with opposite polarity. The separation of the loops' feet determines the thickness of a current sheet that triggers a magnetic reconnection process, and the further formation of a high speed and sharp structure. We analyze the cases where the magnetic filed strength of the two loops is equal and different. In the first case, with a symmetric configuration the spicules raise vertically whereas in an asymmetric configuration the structure shows an inclination. With a number of simulations carried out under a 2.5D approach, we explore various properties of excited jets, namely, the morphology, inclination and velocity. The parameter space involves magnetic field strength between 20 and 40 G, and the resistivity is assumed to be uniform with a constant value of the order $10^{-2}Ω\cdot m$

description: In this work, the second-quantized version of the spatial-coordinate operator, known as the Newton-Wigner-Pryce operator, is explicitly given w.r.t. the massless scalar field. Moreover, transformations of the conformal group are calculated on eigenfunctions of this operator in order to investigate the covariance group w.r.t. probability amplitudes of localizing particles.
