description: Motivated by a recently found class of AdS(7) solutions, we classify AdS(5) solutions in massive IIA, finding infinitely many new analytical examples. We reduce the general problem to a set of PDEs, determining the local internal metric, which is a fibration over a surface. Under a certain simplifying assumption, we are then able to analytically solve the PDEs and give a complete list of all solutions. Among these, one class is new and regular. These spaces can be related to the AdS(7) solutions via a simple universal map for the metric, dilaton and fluxes. The natural interpretation of this map is that the dual CFT6 and CFT4 are related by twisted compactification on a Riemann surface Sigma(g). The ratio of their free energy coefficients is proportional to the Euler characteristic of Sigma(g). As a byproduct, we also find the analytic expression for the AdS(7) solutions, which were previously known only numerically. We determine the free energy for simple examples: it is a simple cubic function of the flux integers.

description: Mobile players in men's football are highly skilled professionals who move to a country other than the one where they grew up and started their careers. They are commonly described as migrants or expatriate players. Due to a much less advanced stage of professionalism and production of the game in women's football mobility projects are different. At describing the cases of Brazil, Equatorial Guinea, Mexico, Colombia and Portugal, the aim of this paper is to conceptualise an umbrella category for mobile players that can include current realities in the women's game, namely the transnational player who has gained and displays transnational football experience in different countries and socio-culturally contexts. Furthermore, analyses allow introducing two new subcategories besides the "expatriate", namely diaspora players and new citizens.

description: In this paper we investigate the localisation of SUSY-breaking branes which, in the smeared approximation, support specific non-BPS vacua. We show, for a wide class of boundary conditions, that there is no flux vacuum when the branes are described by a genuine delta-function. Even more, we find that the smeared solution is the unique solution with a regular brane profile. Our setup consists of a non-BPS AdS(7) solution in massive IIA supergravity with smeared anti-D6-branes and fluxes T-dual to ISD fluxes in IIB supergravity.

We summarize the results of our discussions, which include a better understanding of the analysis choices made by groups and their motivation. We find that the energy spectra determined by the larger experiments are consistent in normalization and shape after energy scaling factors are applied. Those scaling factors are within systematic uncertainties in the energy scale, and we discuss future work aimed at reducing these systematics.

description: In situ forming depots (ISFDs) represent attractive alternatives to the conventional sustained drug delivery systems. Carvedilol, a short half-life drug used on a daily basis to manage chronic conditions, could benefit from this technology. The aim of this work was to develop, for the first time, a new injectable long-acting carvedilol-ISFD. Accordingly, 4 different grades of polyesters with varying properties as i) lactide-to glycolide ratio (polylactide-co-glycolide (PLGA) vs. polylactide (PLA)), and ii) end functionality (acid- vs. ester-capped) were utilized for the preparation of ISFD formulations. In addition, 4 different organic solvents with varying properties (i.e. N-methyl-2-pyrrolidone (NMP), dimethyl sulfoxide (DMSO), ethyl acetate, and benzyl benzoate) were also investigated. It was found that NMP and DMSO were more suitable for the formation of depots. Furthermore, all ISFD formulations demonstrated excellent encapsulation efficiency (i.e. 96–98%). Interestingly, both PLGA-based ISFDs (acid-capped and ester-capped) exhibited similar release behaviors and were able to extend carvedilol release over 30 days. On the other hand, acid-capped and ester-capped PLA-based ISFDs exhibited slower release over the 30 days with an average release of only 36% and 60%, respectively. In conclusion, the developed carvedilol-ISFDs resulted in a tunable extended-release behavior, simply by choosing the appropriate grade of polymer. These results open the door toward a novel injectable carvedilol-ISFD formulation.

description: Executive Summary:
This report documents an analysis of traffic crash data in Kentucky for the years of 2014-2018. A primary objective of this study was to determine average crash statistics for Kentucky highways. Rates were calculated for various types of highways and for counties and cities. Difference criteria were used for exposure.
Average and critical numbers and rates of crashes were calculated for various types of highways in rural and urban areas. These rates used crashes identified on highways where traffic volumes were available. Improved methods of identifying crash locations have resulted in higher rates for the last couple of years. The crash rate data can be used in Kentucky’s procedure to identify locations that have abnormal rates or numbers of crashes.
The other primary objective of this study was to provide data that can be used in the preparation of the problem identification portion of Kentucky’s Annual Highway Safety Plan. County and city crash statistics were analyzed. A summary of results and recommendations in several problem identification areas is presented. These general areas include; alcohol involvement, occupant protection, speed, teenage drivers, pedestrians, bicycles, motorcycles, trucks, and vehicle defects. Other areas included in the analysis for which specific recommendations were not made include, school bus crashes and train crashes.
The crash data are stored in the Collision Report Analysis for Safer Highways (CRASH) database. This database is updated daily so the number of crashes in a given calendar year will continue to change for a substantial time after the end of that year.

description: Many proposed quantum mechanical models of black holes include highly non-local interactions. The time required for thermalization to occur in such models should reflect the relaxation times associated with classical black holes in general relativity. Moreover, the time required for a particularly strong form of thermalization to occur, sometimes known as scrambling, determines the time scale on which black holes should start to release information. It has been conjectured that black holes scramble in a time logarithmic in their entropy, and that no system in nature can scramble faster. In this article, we address the conjecture from two directions. First, we exhibit two examples of systems that do indeed scramble in logarithmic time: Brownian quantum circuits and the antiferromagnetic Ising model on a sparse random graph. Unfortunately, both fail to be truly ideal fast scramblers for reasons we discuss. Second, we use Lieb-Robinson techniques to prove a logarithmic lower bound on the scrambling time of systems with finite norm terms in their Hamiltonian. The bound holds in spite of any nonlocal structure in the Hamiltonian, which might permit every degree of freedom to interact directly with every other one.

description: In this letter we propose the Rao test as a simpler alternative to the generalized likelihood ratio test (GLRT) for multisensor fusion. We consider sensors observing an unknown deterministic parameter with symmetric and unimodal noise. A decision fusion center (DFC) receives quantized sensor observations through error-prone binary symmetric channels and makes a global decision. We analyze the optimal quantizer thresholds and we study the performance of the Rao test in comparison to the GLRT. Also, a theoretical comparison is made and asymptotic performance is derived in a scenario with homogeneous sensors. All the results are confirmed through simulations.

description: Co-amorphous systems are an evolving strategy to stabilize the amorphous form of a drug molecule with the aim of overcoming its poor water-solubility. With research focussing on the molecular level of co-amorphous systems, little is known about their downstream processing. In this study, tablets of co-amorphous carvedilol and aspartic acid (CAR-ASP) with calcium hydrogen phosphate and croscarmellose sodium as excipients were produced using a compaction simulator. The amorphous form of spray dried CAR-ASP and the subsequently produced tablets was confirmed with XRPD. Over the storage time of 12 weeks, no recrystallization of the amorphous material was observed. A central composite face-centred design with three factors was set up to investigate the interplay of formulation and processing variables with the tablet characteristics elastic work, tensile strength and disintegration time. As a result, increasing the amount of co-amorphous material led to a decrease in elastic work and an increased tensile strength. These effects were beneficial for tablet properties, namely harder tablets and reduced elasticity. Disintegration time was prolonged by amounts of up to 25–30% co-amorphous material, while larger amounts induced faster tablet disintegration. While showing the feasibility of compacting co-amorphous material with calcium hydrogen phosphate, this study also gives insight into how tablet characteristics are affected by co-amorphous material and relevant process parameters.

description: The study area is situated in the Main Ethiopian Rift (MER), Southern Ethiopia, close to the western margin of the rift. The objective of this study is to conduct a petrographic investigation and geochemical analysis of Midre Kebd area to constrain geological processes, mantle source composition, compare and contrast with other volcanic sequences in the MER and Northwestern Ethiopia plateau continental flood basalts. The petrographic investigation of the studied area is dominated by basalts, rhyolite, and ignimbrites.

The Midre Kebd basaltic rocks are classified into three groups based on their ages; these include Quaternary, Lower Miocene, and Oligocene basalts. The result of major and trace element data have been used to classify geochemically two distinct types namely alkaline and tholeiitic. Tholeiitic basalts (Oligocene basalts) display low TiO2 (2.15-2.47%), P2O5 (0.28-0.34%), Al2O3 (13.88-14.58%), and high CaO/Al2O3 (0.68-0.72), La/Nb (0.89-1.10), SiO2 (50.2-51.2%). In contrast alkaline basalts (Quaternary and Low Miocene basalts) display high TiO2 (2.4-2.53%), P2O5 (0.44-0.52%), Al2O3 (15.35-15.6%), K2O (0.85-1.08%), and low, CaO/Al2O3 (0.62-0.66) La/Nb (0.71-0.76), SiO2 (46.84-47.84%).

description: We use density functional theory to describe the phase behaviors of rigid molecules. The construction of kernel function G(x, P, x, P) is discussed. Excluded-volume potential is calculated for two types of molecules with C_{2v} symmetry. Molecular symmetries lead to the symmetries of G and density function f(P), enabling a reduction of configuration space. By approximating G with a polynomial, the system can be fully characterized by some moments corresponding to the form of G. The symmetries of G determine the form of the polynomial, while the coefficients are determined by temperature and molecular parameters. The analysis of the impact of coefficients helps us to choose independent variables in the moments as order parameters. Order parameters for bent-core molecules are predicted.

description: Whilst FPGAs have enjoyed success in accelerating high-frequency financial workloads for some time, their use for quantitative finance, which is the use of mathematical models to analyse financial markets and securities, has been far more limited to-date. Currently, CPUs are the most common architecture for such workloads, and an important question is whether FPGAs can ameliorate some of the bottlenecks encountered on those architectures. In this paper we extend our previous work accelerating the industry standard Securities Technology Analysis Center's (STAC\textregistered) derivatives risk analysis benchmark STAC-A2\texttrademark{}, by first porting this from our previous Xilinx implementation to an Intel Stratix-10 FPGA, exploring the challenges encountered when moving from one FPGA architecture to another and suitability of techniques. We then present a host-data-streaming approach that ultimately outperforms our previous version on a Xilinx Alveo U280 FPGA by up to 4.6 times and requiring 9 times less energy at the largest problem size, while outperforming the CPU and GPU versions by up to 8.2 and 5.2 times respectively. The result of this work is a significant enhancement in FPGA performance against the previous version for this industry standard benchmark running on both Xilinx and Intel FPGAs, and furthermore an exploration of optimisation and porting techniques that can be applied to other HPC workloads.
description: This work uses a benchmark of STAC, whilst this was approved at the time they have asked we remove the paper as it needs to be made more explicit that these are unofficial ports and are entirely independent from any vendor and don't follow STAC rules. As we are comparing vendor hardware in the paper, it was felt that this could easily be mistaken to be representing something that the paper is not

description: Degeneracies of non-Hermitian Hamiltonian i.e., exceptional points (EPs) of parity-time (PT)-symmetric systems have received considerable research attention due to their various possible applications in optical devices. At EPs, at least two eigenvalues as well as their eigenvector coalesce. Recently, the effect of the eigenfrequency splitting on transfer function near EP was studied for an optical system consisting of two micro ring resonators, which led to complex splitting in PT-symmetric and anti-PT-symmetric sensors. In present work, we propose a simple system of three coupled ring resonators to show real splitting in both PT-symmetric and anti-PT-symmetric parameter domains by exploiting higher-order EPs. We indirectly couple two rings with equal amount of gain and loss via an intermediate neutral ring. This system is then tested for refractive index (RI) sensing by modulating the cladding index and we numerically show a huge enhancement in sensitivity as compared to those reported in previous studies of micro ring resonators. Importantly, the enhancement is found to be of the order of 10^8. Further, we have found that the order of EP can be tuned by perturbating the cladding. The outcomes of this study may set up a wide range of applications in non-Hermitian triplet cavity systems.

description: Постановка проблемы. Применение активных фазированных антенных решеток (АФАР) в антенных устройствах (АУ) систем связи, передачи данных, радиолокации и др. обеспечивает расширение функциональных возможностей АУ. Однако недостатком АФАР является высокая стоимость из-за использования малошумящих усилителей и усилителей мощности в каждом канале, поэтому снижение стоимости АФАР является одной из первоочередных задач при проектировании.
Цель. Разработать метод синтеза излучающей системы (ИС) АФАР на основе ее топологической оптимизации с целью снижения числа каналов в АФАР и провести анализ характеристик АФАР с синтезированной топологией ИС и исследование зависимости уровня боковых лепестков (УБЛ) диаграммы направленности (ДН) АФАР с синтезированной ИС от сектора сканирования.
Результаты. Получены объемные ДН для ИС, синтезированные с помощью предложенного метода, и зависимости УБЛ от угла сканирования для ИС с квадратным раскрывом размерами 27×27 и 39×39 элементов и с круглым раскрывом диаметром 27 и 39 элементов.
Практическая значимость. Применение предложенного метода позволяет значительно снизить число каналов АФАР и, соответственно, стоимость приемопередающей части АФАР. Так, при снижении числа каналов на 53,3% обеспечивается сканирование ДН в секторе ±30° с ухудшением КНД при максимальном отклонении на 2…2,3 дБ относительно эквидистантной ИС. Величина УБЛ синтезированной ИС превышает УБЛ эквидистантной ИС на 3…5 дБ при неотклоненной ДН и до 10 дБ при отклонении ДН на 30° по углу места и азимуту.

title: Soft matter reaction-diffusion and ferrofluid patterns as dynamic microchannels for optoelectronic lab-on-a-chip with the field-controlled geometry / topology

description: Well known microfluidic or optofluidic devices based on CMOS and CCD sensors, which can be used for measuring the optical characteristics of the liquid samples in solid (either plastic or glass) micro-channels, are strongly predetermined geometrical systems (topologies), which can not be reconfigured after fabrication (a fortiori in situ). We propose a novel approach to the design of the lab-on-a-chip with the real-time controlled topology based on the field-driven soft matter constructions on the CMOS surface. The above approach to the formation, tracing and rearrangement of the channels and the multi-channel topologies is a superimposition of the soft-matter electronics, flexible electronics, electrostatic-driven polymer physics, stretchable electronics, including biomimetic one, and also of ferrohydrodynamics and magnetic particle assisted microhydrodynamics.

description: Here we propose a novel approach towards lab-on-a-chip manufacturing combining synthesis of the chip material with its geometry formation controlled by the physical and chemical properties of its material, which are in these manufacturing conditions inseparable from its particular geometry arising from the principles of crystallography and microcrystallomorphological analysis. In this case, the problems of the chip assembly are replaced by the problems of the layered coating growth on the substrate, while the multilayer material formation provides the programmable variation of the resulting chip properties determined by the number and geometry of the converter layers. The chip / surface geometry is optimized by the free energy minimization in the course of conservative layer-by-layer (LBL) self-assembly process.

description: In this study we introduce a new in situ technique which allows the determination of the boron isotopic composition and B/Ca ratios simultaneously at the nanogram level using a combination of optical emission spectroscopy and multiple ion counting MC ICP-MS with laser ablation. This technique offers a new application in the paleo-field of oceanography and climatology since small samples like e.g. single foraminiferal shells can be analyzed. The simultaneous determination of the boron isotopic composition and B/Ca ratios provides two independent proxies which allow the reconstruction of the full carbonate system. To test the new technique we performed measurements on the cultured, benthic foraminifer Amphistegina lessonii. Our results yielded an average boron isotopic composition δ11B=18.0±0.83‰ (SD) with an average internal precision of 0.52‰ (RSE). The boron concentration was 53±7μg/g (SD). These results agree with the range reported in the literature. The reconstructed mean pH value is in excellent agreement with the measured pH of the seawater in which the foraminifers grew. The analysis of a foraminifer consumed approximately 1200. ng calcium carbonate containing ca. 0.06. ng boron. Compared to bulk analytical methods, this new technique requires less material and reduces the time for sample preparation.

description: The European XFEL is a new research facility currently under construction at DESY in the Hamburg area in Germany. From 2015 on, it will generate extremely intense X-ray flashes that will be used by researchers from all over the world. The superconducting XFEL linear accelerator consists of 100 accelerator modules with more than 800 RF-cavities inside. The accelerator modules, superconducting magnets and cavities will be tested in the accelerator module test facility (AMTF). This paper gives an overview of the design parameters and the commissioning of the vertical insert, used in two cryostats (XATC) of the AMTF-hall. The Insert serves as a holder for 4 nine-cell cavities. This gives the possibility to cool down 4 cavities to 2K in parallel and, consequently, to reduce the testing time. The following RF measurement, selected as quality check, will be done separately for each cavity. Afterwards the cavities will be warmed up again and will be sent to the accelerator module assembly.

description: We present new closed-form expressions for certain improper integrals of Mathematical Physics such as certain Ising, Box, and Associated integrals. The techniques we employ here include (a) the Method of Brackets and its modifications and suitable extensions to obtain the Mellin-Barnes representation. (b) The evaluation of the resulting Mellin-Barnes representations via the recently discovered Conic Hull method via the automated package $\textit{MBConichulls.wl}$. Finally, the analytic continuations of these series solutions are then produced using the automated package \texttt{Olsson.wl}, based on the method of Olsson. Thus, combining all these recent advances allows for closed-form evaluation of the hitherto unknown $B_3(s)$, $B_4(s)$, and related integrals in terms of multivariable hypergeometric functions. Along the way, we also discuss certain complications while using the Original Method of Brackets for these evaluations and how to rectify them. The interesting cases of $C_{5,k}$ are also studied. It is not yet fully resolved for the reasons we discuss in this paper.

Giant conductance and phase time anomalous events of hole quantum transport

description: Events of giant conductance and anomalies of the phase transmission time for holes, are theoretically investigated within the multicomponent scattering approach. Based on this model, new analytical expressions for unitarity relations in the uncoupled hole transport are obtained and directly applied to study the behavior of the conductance and the phase transmission time in a double barrier resonant tunneling (DBRT) and a superlattice $GaAs$-cladding layer$/(AlAs/GaAs)^{n}/GaAs$-cladding layer. Clear-signature evidences of giant conductance phenomena for hole transmission without valence-band mixing through a DBRT and a superlattice were found. The giant conductance effect losses robustness by manipulating the number of superlattice layers and by including the valence-band particles coupling as well. Phase time through the heterostructure exhibits extremal dependencies in the gaps and in the barriers, as those reported before for electrons. We have detected an earlier arrival phase time for the propagation of both flavors of holes within the barrier, in the order of few tenths of picoseconds. An appealing filter-like effect is presented, whenever a selective confinement strength arises independently for both flavors of holes in the uncoupled regime. Our results also prescribe noticeable evidences for both uncoupled and coupled hole fluxes, similar to those foretold by Hartman, upon transmission of electrons through opaque barriers.

description: In this study, in order to explain the solvent and spin state effects on the molecular structure of catechol-Fe complex [Fe(cat)3]n﹣ where n = 2 and 3, Hartree Fock (HF)-Density Functional Theory (DFT) hybrid calculations are performed at the B3LYP/6-311g(d,p) level of theory. The binding energies of Fe2+ and Fe3+ in high-spin state are higher than intermediate and low-spin states which show that the complex formation in a high spin state is more favorable. The calculated binding energies at different solvents indicate that the binding energies in polar solvents are lower than non-polar solvents. Furthermore, spectroscopic studies including FTIR and Raman spectrum in various solvents reveal that the formation of intermolecular bonds between the oxygen atom of carbonyl group and the hydrogen atom of solvent causes a spectral red shift. The calculated FTIR and geometry parameters are in good agreement with previous experimental data. Donor-acceptor interaction energies are evaluated due to the importance of the charge transfer in the complex formation. It is observed that the free electrons of oxygen atom interact with the antibonding orbitals of the iron. Finally, some correlations between the quantum chemical reactivity indices of the complexes and solvent polarity are considered. The study indicates a linear correlation between chemical hardness and binding energies of [Fe(cat)3]3﹣ complex.
