description: We study how a high-speed solar wind stream embedded in a slow solar wind affects the transport and energy changes of solar energetic protons in interplanetary space, assuming different levels of cross-field diffusion. This is done using a particle transport model that computes directional particle intensities and first order parallel anisotropies in a background solar wind generated by the magnetohydrodynamic model EUHFORIA. In particular, we consider a mono-energetic 4 MeV proton injection over an extended region located at a heliographic radial distance of 0.1 AU. By using different values for the perpendicular proton mean free path, we study how cross-field diffusion may affect the energetic particle spread and intensity profiles near a high-speed solar wind stream and a corotating interaction region (CIR). We find that both a strong cross-field diffusion and a solar wind rarefaction region are capable of dispersing SEPs efficiently, producing overall low particle intensities which can in some cases prevent the SEPs from being detected in-situ, since their intensity may drop below the detected pre-event intensity levels. We also discuss how accelerated particle populations form on the reverse and forward shock waves, separated by the stream interface inside the CIR. Under strong levels of cross-field diffusion, particles cross the SI and hence both accelerated particle populations merge together.

description: A two-dimensional Ising model with short-range interactions and mobile defects describing the formation and thermal destruction of defect stripes is studied. In particular, the effect of a local pinning of the defects at the sites of straight equidistant lines is analysed using Monte Carlo simulations and the transfer matrix method. The pinning leads to a long-range ordered magnetic phase at low temperatures. The dependence of the phase transition temperature, at which the defect stripes are destabilized, on the pinning strength is determined. The transition seems to be of first order, with and without pinning.

description: Polymorphisms of Toll-like receptor 4 (TLR4) as a key player in cell proliferation, apoptosis, and angiogenesis have been linked to colorectal cancer (CRC) in different populations. We aimed in this study to determine genetic associations of TLR4 variants with CRC progression in Egyptian patients. Genotype and allelic frequencies of Asp299Gly (rs4986790) and Thr399Ile (rs4986791) were compared between 127 CRC patients and 141 healthy Egyptians using restriction fragment length polymorphism, and were correlated to clinicopathological findings. Results revealed that the variant alleles (G of Asp299Gly) and (T of Thr399Ile) were significantly associated with CRC among Egyptians. Confirmed by haplotype analysis, AT and GT haplotypes were more frequent in CRC patients than controls with increased CRC odds (OR = 3.54 and 3.45, 95% CI = 1.48–8.48 and 1.09−10.83, respectively). In addition, the G allele of Asp299Gly SNP was observed to be significantly associated with progressive CRC, including stage IV (P = .001), grade III (P = .025), N2 lymph nodes (P = .020), and metastasis (P = .001). On the other hand, Thr399Ile variant did not show any association with tumor behavior. Taken together, we conclude a significant association of Asp299Gly and Thr399Ile variants with the risk of development of CRC in Egypt. Asp299Gly variant, but not the Thr399Ile variant, may serve as a biomarker of this disease progression in Egyptian population.

description: The wide use of artificial insemination by dairy farmers has facilitated the development of a multi-billion dollar international market in animal genetics. In the major western dairy producing nations, each country has developed a single index to rank bulls, based on the value of traits they are expected to pass on to their offspring. One of the assumptions behind these indexes is that there is a positive linear relationship between profit (and welfare) with increases in a particular trait, regardless of the farm system. In this paper, it is shown, with examples, that the assumption of linearity is false. More importantly, it is shown that for a combination of reasons, including risk aversion, constraints and other issues, the optimal direction of genetic improvement for New Zealand dairy farmers on an individual and industry level could be quite different. Alternatives to the “one size fits all” index are described.

description: Bei der konventionellen Drehmomentregelung von Permanentmagneterregten Synchronmaschinen (PSM) werden Solldrehmomente unter der Berücksichtigung von Leistungsverlusten durch statische Kennfelder in Sollströme überführt. Dieses Vorgehen ist dynamisch suboptimal, interdependent und stark maschinenabhängig. Diese Arbeit widmet sich der Frage: Wie kann ein Model Predictive Controller (MPC) entworfen werden, durch welchen die Ziele Drehmomenterreichung und Verlustminimierung simultan optimiert werden und wie können die gesteigerten Anforderungen in der Elektromobilität durch diesen Ansatz erfüllt werden? Hierfür wird die Beschreibung des Regelziels im MPC als multikriterielles lexikographisches Optimierungsproblem (LOP) formuliert, was einer strengen Priorisierung der beiden Regelziele entspricht. Um diesen Ansatz für echtzeitfähige Systeme tauglich zu machen, wird für die Integration des LOP in den MPC eine neue Methode vorgeschlagen, die beide Regelziele in eine Gütefunktion transformiert. Die Anforderungen der Elektromobilität werden im MPC durch die Berücksichtigung der Nichtlinearität des magnetischen Kreises – insbesondere Sättigung, Reluktanz und Kreuzverkopplung – sowie exakter Spannungs- und Strombegrenzung berücksichtigt. Durch die neue zugeschnittene Methode wird die mittlere Berechnungszeit des LOP deutlich verringert und gleichzeitig das Regelergebnis verbessert. Die Analyse der Potentiale dieses Ansatzes erfolgt im Vergleich mit einem PI-Zustandsregler durch die Untersuchung der jeweils erzielbaren Regelergebnisse in anwendungsnahen Szenarien. Bei der Anwendung der Regler auf die Kompensation von Getriebeschwingungen im Antriebsstrang eines Elektrofahrzeugs zeigt das vorgeschlagene Verfahren zusätzliche Potentiale für schnelle dynamische Vorgänge an den Betriebsgrenzen.

description: Virus H5N1 is confirmed as the cause of AI in Indonesia as well as in other Asia countries. A possible human pandemic from AI has economic implications and may affect consumer behavior as well as other sectors such as tourist, trade and transportation. A Computable General Equilibrium (CGE) model is used to analyze the impact of the recent AI outbreak on the Indonesian macro and sectoral economy as well as on income distribution. The model is a combination of INDOF (Oktaviani, 2000), and WAYANG (Wittwer, 2002). Even though the contribution of the poultry sector is relatively small in the Indonesian economy, the AI outbreak had significant impacts at sectoral and macro levels. Government action to control AI is important if welfare is to be maintained amongst the most vulnerable groups in society.

description: Multiple sclerosis (MS) affects the central nervous system with a wide range of symptoms. MS can, for example, cause pain, changes in mood and fatigue, and may impair a person's movement, speech and visual functions. Diagnosis of MS typically involves a combination of complex clinical assessments and tests to rule out other diseases with similar symptoms. New technologies, such as smartphone monitoring in free-living conditions, could potentially aid in objectively assessing the symptoms of MS by quantifying symptom presence and intensity over long periods of time. Here, we present a deep-learning approach to diagnosing MS from smartphone-derived digital biomarkers that uses a novel combination of a multilayer perceptron with neural soft attention to improve learning of patterns in long-term smartphone monitoring data. Using data from a cohort of 774 participants, we demonstrate that our deep-learning models are able to distinguish between people with and without MS with an area under the receiver operating characteristic curve of 0.88 (95% CI: 0.70, 0.88). Our experimental results indicate that digital biomarkers derived from smartphone data could in the future be used as additional diagnostic criteria for MS.

description: Natural and semi-natural grassland communities in Bulgaria are subjected to anthropogenic pressure leading to their reduction and fragmentation. Since they are home to many other groups of living organisms, this poses serious challenges concerning their conservation and sustainable use. We present results of studies on the floristic and habitat diversity of diverse grassland communities in the plain areas of Bulgaria. The diversity evaluation was based on 38 experimental plots situated mostly in the eastern and northern parts of the country. More than 400 plant species and 12 habitat types were identified so far. Calculated diversity indices revealed that species richness varies substantially among the different habitats, with no clear trend detected. It is shaped by numerous environmental factors, and to a considerable extent – by the anthropogenic pressure. The threats to plant and habitat diversity are reviewed, and the conservation measures are discussed.

description: We present an enhanced version of the multiwavelength spectral modeling code MAGPHYS that allows the estimation of galaxy photometric redshift and physical properties (e.g., stellar mass, star formation rate, dust attenuation) simultaneously, together with robust characterization of their uncertainties. The self-consistent modeling over ultraviolet to radio wavelengths in MAGPHYS+photo-z is unique compared to standard photometric redshift codes. The broader wavelength consideration is particularly useful for breaking certain degeneracies in color vs. redshift for dusty galaxies with limited observer-frame ultraviolet and optical data (or upper limits). We demonstrate the success of the code in estimating redshifts and physical properties for over 4,000 infrared-detected galaxies at 0.4

description: The problem of summation of the perturbation series for the process of lepton pair production in relativistic ion collisions is investigated. We show that the amplitude of this process can be obtained in the compact analytical form, if one confines to the terms growing as a powers of logarithm energy in the cross section, the approximation of which is completely justified for such colliders as RHIC and LHC. Using this result we calculate the Coulomb corrections to the cross section of the process under consideration.

description: Hiroshima University, Japan ()1); Presidency University, Kolkata, India (2); Durgapur Govt. College, Durgapur, India (3) br brThe nature of the shallow-crustal active faults has been widely studied to elucidate their stress accommodation mechanisms and response to the fault movement in terms of stress localizations and ultimately stress release by rupture or creep mechanisms. The Main Frontal Thrust (MFT) and its hinterland area are at present the most tectonically active zones within the Himalayan orogen accommodating northward convergence of India against the Eurasian plate with periodic release of accumulating strain energy through moderate–large earthquakes. This work is a first report on detailed microstructural and mineralogical studies from fault gouges of the Nahan Thrust (NT) occurring in the vicinity of MFT. The NT exhibits a ~150 m wide fault core-damage zone in the studied area, where the fault core consists of grey-green, red and black gouge layers. The intact rocks comprise alternations of arenitic and argillaceous sandstone, while the damage zone consists of crackle to mosaic and foliated breccia. The modal mineral analysis of the fault core rocks and the intact rocks determined in conjunction with SEM-BSE, EPMA, and image processing by ImageJ software (Schneider et al., 2012), suggests that the original rock of the grey-green and black gouge layers is the arenitic sandstone, while that of the red gouge layers is the argillaceous sandstone. Microstructures indicate dominance of stress localization and cataclasis in the grey-green gouge, while pressure solution creep in the red gouge. Additionally, the calcite vein fragments present in the red gouge show development of Type-I deformation twins indicating the overall temperature of deformation ~170℃ (Rowe and Rutter, 1990; Burkhard, 1993; Ferrill et al., 2004). However, the black gouge layer shows development of ultracataclasite-rich principal slip zones with degassing bubbles and clay clast aggregates (CCA), indicating localized frictional heating and possible seismic faulting (Boutareaud et al., 2008; Tesei et al., 2014). Hence, this study proposes that the arenitic sandstone suffered seismic rupture, while the argillaceous sandstone deformed aseismically, implying a strong lithological dependence on the seismic cycle within the Nahan thrust.

description: 3-D topological insulators (TI) with large spin Hall conductivity have emerged as potential candidates for spintronic applications. Here, we report spin to charge conversion in bilayers of amorphous ferromagnet (FM) Fe_{78}Ga_{13}B_{9} (FeGaB) and 3-D TI Bi_{85}Sb_{15} (BiSb) activated by two complementary techniques: spin pumping and ultrafast spin-current injection. DC magnetization measurements establish the soft magnetic character of FeGaB films, which remains unaltered in the heterostructures of FeGaB-BiSb. Broadband ferromagnetic resonance (FMR) studies reveal enhanced damping of precessing magnetization and large value of spin mixing conductance (5.03 x 10^{19} m^{-2}) as the spin angular momentum leaks into the TI layer. Magnetic field controlled bipolar dc voltage generated across the TI layer by inverse spin Hall effect is analyzed to extract the values of spin Hall angle and spin diffusion length of BiSb. The spin pumping parameters derived from the measurements of the femtosecond light-pulse-induced terahertz emission are consistent with the result of FMR. Kubo-Bastin formula and tight-binding model calculations shed light on the thickness-dependent spin-Hall conductivity of the TI films, with predictions that are in remarkable agreement with the experimental data. Our results suggest that room temperature deposited amorphous and polycrystalline heterostructures provide a promising platform for creating novel spin orbit torque devices.

description: We investigate the evolution of abundance of the asymmetric thermal Dark Matter when its annihilation rate at chemical decoupling is boosted by the Sommerfeld enhancement. Then we discuss the effect of kinetic decoupling on relic abundance of asymmetric Dark Matter when the interaction rate depends on the velocity. Usually the relic density of asymmetric Dark Matter is analyzed in the frame of chemical decoupling. Indeed after decoupling from the chemical equilibrium, asymmetric Dark Matter particles and anti--particles were still in kinetic equilibrium for a while. It has no effect on the case of $s-$wave annihilation since there is no temperature dependence in this case. However, the kinetic decoupling has impacts for the case of $p-$wave annihilation and Sommerfeld enhanced $s-$ and $p-$wave annihilations. We investigate in which extent the kinetic decoupling affects the relic abundances of asymmetric Dark Matter particle and anti--particle in detail. We found the constraints on the cross section and asymmetry factor by using the observational data of relic density of Dark Matter.

description: We have constructed a Monte Carlo generator for lowest-order predictions for the processes gamma gamma -> 4f and gamma gamma -> 4f+gamma in the Standard Model and extensions thereof by an effective gamma gamma Higgs coupling as well as anomalous triple and quartic gauge-boson couplings. Polarization is fully supported, and a realistic photon beam spectrum can be taken into account. For the processes gamma gamma -> 4f all helicity amplitudes are explicitly given in a compact form. The presented numerical results contain, in particular, a survey of cross sections for representative final states and their comparison to results obtained with the program package Whizard/Madgraph. The impact of a realistic beam spectrum on cross sections and distributions is illustrated. Moreover, the size of various contributions to cross sections, such as from weak charged- or neutral-current, or from strong interactions, is analyzed. Particular attention is paid to W-pair production channels gamma gamma -> W W -> 4f(+gamma) where we investigate the impact of background diagrams, possible definitions of the W-pair signal, and the issue of gauge-invariance violation caused by finite gauge-boson widths. Finally, the effects of triple and quartic anomalous gauge-boson couplings on cross sections as well as the possibility to constrain these anomalous couplings at future gamma gamma colliders are discussed.

description: We present calculations of magnetic field evolution by the Hall effect and Ohmic decay in neutron star crusts. We first discuss when and for which neutron stars the Hall effect is important relative to Ohmic decay. We compute the evolution of an initial field distribution by Ohmic decay, and give approximate analytic formulas for both the surface and interior fields as a function of time. We then discuss the subsequent evolution by the Hall effect, giving several examples which illustrate how the field configuration evolves. Hall wave eigenfunctions are computed, including the effect of the large density change across the crust. We estimate the response of the crust to the magnetic stresses induced by Hall waves, and give a detailed discussion of the boundary conditions at the solid-liquid interface. Finally, we discuss the implications for the Hall cascade proposed by Goldreich & Reisenegger.

description: The members of asteroid families have various shapes. We investigate the origin of their shapes by high-resolution impact simulations for catastrophic disruptions using a Smoothed Particle Hydrodynamics code. Collisional remnants produced through our simulations of the catastrophic disruptions mainly have spherical or bilobed shapes. However, no flat remnants with the ratio of minor to major axis lengths c/a < 0.5 are formed. The results of the simulations provide various shapes of asteroids and explain most of the shapes in asteroid families that are supposed to be produced through catastrophic disruptions. However, the present simulations do not explain significantly flat asteroids. We suggest that these flat asteroids may be interlopers or formed through low-velocity collisions between member asteroids.

description: University of Montana, United States of America

The Williston Basin is an intracratonic basin in Canada and the USA, located atop the structurally complex suture zone between the Archean Superior province to the east and the Archean basement of the Wyoming structural provinces to the west. The basin in general has a very homogeneous subsidence history throughout most of the Paleozoic, that can be largely explained by simple thermal subsidence. This simple subsidence model should result in a very predictive facies distribution with more proximal facies near the basin margin and the more distal deposition near the basin center. Although this type of regional facies distribution is present during large parts of the Devonian, including the Famennian Lower Bakken Shale deposition, the Pronghorn Member of the Bakken Formation does not adhere to this model. Results from detailed (sub-centimeter scale) lithofacies descriptions and chemostratigraphy from 26 cores from North Dakota and Saskatchewan suggests that the Pronghorn Member changes in facies, composition, and thickness along known structural lineaments, such as the Weldon-Brockton-Froid Zone and the Goose Lake Trend. The data presented here suggests that these lineaments were active during the latest Devonian and dissected the Williston Basin into multiple sub-basins during Pronghorn deposition. This detailed facies and chemostratigraphy study provides a new careful look on the controls of late Devonian deposition in the Williston Basin, and food for thought how tectonics might influence deposition in an intracratonic basin located hundreds of miles from an orogenic front.

description: The aim of this study was to evaluate the potential effect of ellagic acid (EA) in the treatment of pancreatic injury. EA has been found to have strong anti-inflammatory, antioxidative, and anticancer properties. The effects of EA on pancreati˜c star cell (PSC) activation and cell functions have been evaluated and it has been shown that it inhibits the activation of basic cell functions and PSCs and. it has antidiabetic activity through its effect on β-pancreas cells. In this work, 36 Wistar albino rats (n = 36, 8 weeks old) were used. Rats were divided to 4 groups and 9 rats were each group. Groups: Group 1: control group; Group 2: EA group; Group 3: carbon tetrachloride (CCl4) group; Group 4: EA + CCl4 group. Animals were decapitated after 8 weeks and their pancreas tissue samples were taken and researched. In pancreas tissue, NF-κB, TNF-α, Nrf-2, VEGF, Bcl-2, caspase-3, and Akt proteins expression ratios were analyzed by western blotting method, CAT activity and GSH levels were determined by spectrophotometer and ROS production was detected by MDA. In our results, the Nrf-2 and caspase-3 protein expressions, catalase activities and GSH levels increased, TNF-α, NF-κB, Bcl-2, VEGF, and Akt protein expressions and MDA levels reduced in EA + CCl4 group comparable to the CCl4 group. These findings reveal that EA decreases pancreas tissue injury in rats and that EA may also be used as a drug against pancreas tissue injury in the future.

description: We investigate the effect of Ni doping on the Fe-site in single crystals of the magnetic superconductor RbEuFe$_4$As$_4$ for doping concentrations of up to 4%. A clear suppression in the superconducting transition temperature is observed in specific heat, resistivity and magnetization measurements. Upon Ni-doping, the resistivity curves shift up in a parallel fashion indicating a strong increase of the residual resistivity due to scattering by charged dopand atoms while the shape of the curve and thus the electronic structure appears largely unchanged. The observed step $ΔC/T_c$ at the superconducting transition decreases strongly for increasing Ni doping in agreement with expectations based on a model of multi-band superconductivity and strong inter-band pairing. The upper critical field slopes are reduced upon Ni doping for in- as well as out-of-plane fields leading to a small reduction in the superconducting anisotropy. The specific heat measurements of the magnetic transition reveal the same BKT behavior close to the transition temperature $T_m$ for all doping levels. The transition temperature is essentially unchanged upon doping. The in to out-of-plane anisotropy of Eu-magnetism observed at small magnetic fields is unaltered as compared to the undoped compound. All of these observations indicate a decoupling of the Eu magnetism from superconductivity and essentially no influence of Ni doping on the Eu magnetism in this compound.

description: We investigate the existence of quantum {\it quasi} phase transitions for an ensemble of ultracold bosons in a one-dimensional optical lattice, performing exact diagonalizations of the Bose-Hubbard Hamiltonian. When an external parabolic potential is added to the system {\it quasi} phase transitions are induced by the competition of on-site mean-field energy, hopping energy, and energy offset among lattice sites due to the external potential and lead to the coexistence of regions of particle localization and delocalization in the lattice. We clarify the microscopic mechanisms responsible for these {\it quasi} phase transitions as a function of the depth of the external potential when the on-site mean-field energy is large compared to the hopping energy. In particular, we show that a model Hamiltonian involving a few Fock states can describe the behavior of energy gap, mean particle numbers per site, and number fluctuations per site almost quantitatively. The role of symmetry on the gap as a function of the depth of the external trapping potential is elucidated. We discuss possible experimental signatures of {\it quasi} phase transitions studying the single particle density matrix and explain microscopically the occurrence of local maxima in the momentum distribution. The role of a thermal population of the excited states on the momentum distribution is discussed.

description: The enhancement of interfacial Dzyaloshinskii-Moriya Interaction (DMI) in magnetic multilayers results in the stabilization of topological spin textures like chiral domain walls and skyrmions. Here we report on the evaluation of interface-driven magnetic interactions in a uniquely designed multilayer where each magnetic layer of two AFM coupled sublattices of 3d and 4f moments is sandwiched between the layers of β-tungsten and holmium whose spin Hall angles are large but opposite in sign. The atomic and magnetic periodicity of these multilayers is established by polarized neutron reflectivity measurements and the presence of a labyrinth domain spin texture of zero remanence with x-ray photoelectron microscopy. Measurements of the Hall resistivity (ρ_{xy}(T, H)) together with static magnetization (M(T,H)) over a broad range of temperature (T) and magnetic field (H) indicate impending compensation between 3d and 4f sublattices at T>350 K. These multilayers are characterized by a small (0.04 %) but positive magnetoresistance indicative of interface enhance scattering and a large (40 nΩ.m) and negative anomalous ρ_{xy}(T,H) which results from a parallel alignment of 4f moments with the external magnetic field. No distinct scaling is seen between ρ_{xy}(T,H), ρ_{xx}(T, H) and M(T,H) at temperatures above 200K where the magnetization develops out-of-plane anisotropy. The field scans of ρ_{xy} at T>200K show a distinct cusp in the vicinity of magnetic saturation. These Hall data have been analyzed in the framework of a model where a distinct topological contribution to ρ_{xy} rides over the anomalous Hall resistivities of the 3d and 4f magnetic sublattices. It is suggested that this apparent topological effect results from an interfacial DMI and dominates ρ_{xy}(T,H) in the temperature regime where the 3d and 4f lattices are nearly compensated.

description: The introduction of the Integrated Projects for the Food Chain (IPFs) requires the development of models capable of interpreting the dynamics of vertical and horizontal coordination between agents and the definition of the issues that most affect the ability of professionals to provide value added to goods and products to acquire in exchange a competitive advantage. With reference to the Basilicata region, the production structure of the region and the recent development of the Integrated Projects for the Food Chain, this research has developed a new model of territorial organization of rural development. To connect a new food chain model that combines theories of productivity, typical of contract economics, with those of social welfare and environmental economics can be crucial: multifunctionality could assume the key role related to the needs of income and efficiency of companies in various stages of the classic food chain, in a context in which planning and consultation are major determinants of local and regional development.

description: This study examines the effect of the composition of federal and state government spending on various important air pollutants in the US using a newly assembled data set of government spending. The results indicate that a reallocation of spending from private goods (RME) to social and public goods (PME) by state and local governments reduces sulfur dioxide concentrations while the composition of federal spending has no effect. A 10% percent increase in the share of state and local social and public goods government spending reduces air pollution concentrations by 3 to 5% for Sulfur Dioxide, 2 to 3% for particulate matter 2.5 and 1 to 2 % for ozone. The results are robust to various sensitivity checks.

description: Nuclear star clusters (NSCs) are found in at least 70% of all galaxies, but their formation path is still unclear. In the most common scenarios, NSCs form in-situ from the galaxy's central gas reservoir, through merging of globular clusters (GCs), or through a combination of the two. As the scenarios pose different expectations for angular momentum and stellar population properties of the NSC in comparison to the host galaxy and the GC system, it is necessary to characterise the stellar light, NSC, and GCs simultaneously. Wide-field observations with modern integral field units such as the Multi Unit Spectroscopic Explorer (MUSE) allow to perform such studies. However, at large distances, NSCs usually are not resolved in MUSE observations. The particularly large NSC (R_eff $\sim$ 66 pc) of the early-type galaxy FCC47 at distance of $\sim$ 20 Mpc is an exception and is therefore an ideal laboratory to constrain NSC formation of external galaxies.
