LARGE ORDER ASYMPTOTICS OF SEMICLASSICAL EXPANSION: A NEW APPROACH

A new approach to the problem of finding the asymptotical behaviour of large orders of semiclassical expansion is suggested. Asymptotics of high orders not only for eigenvalues, but also for eigenfunctions, are constructed. Thus, one can apply not only functional integral technique, which has been used up to now, but also method of direct analysis of the semiclassical expansion recursive relations.
Utilize State-space to Carry on the Question to Solve

The method that the expression method of state space is an important knowledge expression. It is an effective method to solve the question to search for, and generally there are two kinds of knowledge expression methods with corresponding search: one is and or tree expression method, the other is the expression method of state space, which provides how to utilize state space to ask and solve the step of the question in detail,and solved salesman's traveling question with search tactics that the width has priority of the cost tree.
Effects of Gamma Ray Radiation on the Performance of Microelectromechanical Resonators

While much radiation test data are available for metal‐oxide‐semiconductor (MOS) devices, research into the effects of radiation on microelectromechanical systems (MEMS) is in its relative infancy. Piezoelectrically transduced MEMS resonators have broad applications in signal processing, environmental monitoring, and navigation. Aluminum nitride (AlN), in particular, is an attractive piezoelectric because of its favorable fabrication characteristics and ease of integration into the complementary MOS (CMOS) manufacturing process. The utility of these devices in space and nuclear systems necessitates research into their performance in radiation environments. Resiliency and an established relationship between radiation dose and device behavior provide a critical tool for engineers in their design process. Multiple AlN‐based MEMS resonator designs are created and exposed the devices to 1 Mrad(Si) gamma irradiation from a Cobalt‐60 source while measuring scattering (S‐) parameters in situ. The experimental data are matched to a theoretical model to describe the change in frequency as a function of radiation‐induced displacement damage. It is demonstrated that the AlN‐based resonators are resilient against radiation‐induced charge‐trapping effects. Furthermore, a new method is presented of permanent frequency trimming MEMS resonators up to 30% of their bandwidth without modifying quality factor or motional resistance.
Simulation of unsteady laminar flow in models of terminal aneurysm of the basilar artery

Blood flow dynamics play an important role in the pathogenesis and treatment of intracranial aneurysms. The evaluation of the velocity field in the aneurysm dome and neck is important for the correct placement of endovascular coils, in addition the temporal and spatial variations of wall shear stress in the aneurysm are correlated with its growth and rupture. The present numerical investigation describes the hemodynamics in two models of terminal aneurysm of the basilar artery. Aneurysm models with an aspect ratio of 1.0 and 1.67 were studied. Each model was subject to a steady, sinusoidal and physiologically representative waveform of inflow for a mean Reynolds number of 560. Symmetric and asymmetric outflow conditions in the branches were also studied. The three-dimensional continuity and the Navier-Stokes equations for incompressible, unsteady laminar flow with Newtonian properties were solved with a commercial software using non structured grids with 61334 and 65961 cells for models 1 and 2, respectively. The grids were primarily composed of tetrahedral elements. The intra-aneurysmal flow was unsteady for all input conditions and in both models, the flow always showed a complex vortex structure. The inflow and outflow zones in the aneurysm neck were determined. The wall shear stress on the aneurysm showed large temporal and spatial variations. The asymmetric outflow increased the wall shear stress in both models.
Evidence for Black Holes in Stellar Binary Systems

The concept that black holes could actually be present in nature has fascinated both scientists and the general public for years. As early as 1916 Karl Schwarzschild proposed that black holes might exist, and Oppenheimer & Snyder (1939) showed that they could possibly form from massive stars. Although numerous black-hole candidates have been put forward, conclusive proof of their presence has been much harder to find. The fact that even the most likely examples are still referred to in the literature as "candidates" shows our hesitancy to accept their existence. In this review we summarize the observational evidence for black holes in a handful of stellar binary systems which, at present, appear to be the best documented cases. Although numerous observational characteristics have been cited as evidence that a black hole might be present (e.g. millisecond X-ray flicker­ ing, high/low states, two-component X-ray spectrum), the strongest case can be made for those systems in which radial velocity measurements provide a dynamical determination of the collapsed star's mass. Since theoretical work places the upper mass limit for a neutron star at about 3 solar masses (e.g. Chitre & Hartle 1976; see also the review by Baym & Pethick 1979), the most convincing black-hole binaries are those for which the mass measured for the compact star exceeds this limit. Necessary observational criteria include: 1. presence of strong X-ray emission, 2. firm identification of the optical candidate (from data such as correlated X-ray and optical variability), 3. a dynamical mass determination (from radial
A High Performance All-Textile Wearable Antenna for Wristband Application

A compact, conformal, all-textile wearable antenna is proposed in this paper for the 2.45 GHz ISM (Industrial, Scientific and Medical) band. The integrated design consists of a monopole radiator backed by a 2 × 1 Electromagnetic Band Gap (EBG) array, resulting in a small form factor suitable for wristband applications. An EBG unit cell is optimized to work in the desired operating band, the results of which are further explored to achieve bandwidth maximization via floating EBG ground. A monopole radiator is made to work in association with the EBG layer to produce the resonance in the ISM band with plausible radiation characteristics. The fabricated design is tested for free space performance analysis and subjected to human body loading. The proposed antenna design achieves bandwidth of 2.39 GHz to 2.54 GHz with a compact footprint of 35.4 × 82.4 mm2. The experimental investigations reveal that the reported design adequately retains its performance while operating in close proximity to human beings. The presented Specific Absorption Rate (SAR) analysis reveals 0.297 W/kg calculated at 0.5 W input power, which certifies that the proposed antenna is safe for use in wearable devices.
Chromatographic Scalable Method to Isolate Engineered Extracellular Vesicles Derived from Mesenchymal Stem Cells for the Treatment of Liver Fibrosis in Mice

New therapeutic options for liver cirrhosis are needed. Mesenchymal stem cell (MSC)-derived extracellular vesicles (EVs) have emerged as a promising tool for delivering therapeutic factors in regenerative medicine. Our aim is to establish a new therapeutic tool that employs EVs derived from MSCs to deliver therapeutic factors for liver fibrosis. EVs were isolated from supernatants of adipose tissue MSCs, induced-pluripotent-stem-cell-derived MSCs, and umbilical cord perivascular cells (HUCPVC-EVs) by ion exchange chromatography (IEC). To produce engineered EVs, HUCPVCs were transduced with adenoviruses that code for insulin-like growth factor 1 (AdhIGF-I-HUCPVC-EVs) or green fluorescent protein. EVs were characterized by electron microscopy, flow cytometry, ELISA, and proteomic analysis. We evaluated EVs’ antifibrotic effect in thioacetamide-induced liver fibrosis in mice and on hepatic stellate cells in vitro. We found that IEC-isolated HUCPVC-EVs have an analogous phenotype and antifibrotic activity to those isolated by ultracentrifugation. EVs derived from the three MSCs sources showed a similar phenotype and antifibrotic potential. EVs derived from AdhIGF-I-HUCPVC carried IGF-1 and showed a higher therapeutic effect in vitro and in vivo. Remarkably, proteomic analysis revealed that HUCPVC-EVs carry key proteins involved in their antifibrotic process. This scalable MSC-derived EV manufacturing strategy is a promising therapeutic tool for liver fibrosis.
Large deviation for multivalued backward stochastic differential equations

Abstract. We consider a multivalued forward-backward stochastic differential equation where the diffusion coefficient of the forward equation is perturbed by a small parameter ε>0${\varepsilon > 0}$ . We prove that, as ε goes to 0, the solution of the backward equation converges to the solution of a deterministic backward equation and satisfies a Freidlin–Wentzell type large deviation principle.
Synthesis of Ketjenblack Decorated Pillared Ni(Fe) Metal-Organic Frameworks as Precursor Electrocatalysts for Enhancing the Oxygen Evolution Reaction

Metal-organic frameworks (MOFs) have been investigated with regard to the oxygen evolution reaction (OER) due to their structure diversity, high specific surface area, adjustable pore size, and abundant active sites. However, the poor conductivity of most MOFs restricts this application. Herein, through a facile one-step solvothermal method, the Ni-based pillared metal-organic framework [Ni2(BDC)2DABCO] (BDC = 1,4-benzenedicarboxylate, DABCO = 1,4-diazabicyclo[2.2.2]octane), its bimetallic nickel-iron form [Ni(Fe)(BDC)2DABCO], and their modified Ketjenblack (mKB) composites were synthesized and tested toward OER in an alkaline medium (KOH 1 mol L−1). A synergistic effect of the bimetallic nickel-iron MOF and the conductive mKB additive enhanced the catalytic activity of the MOF/mKB composites. All MOF/mKB composite samples (7, 14, 22, and 34 wt.% mKB) indicated much higher OER performances than the MOFs and mKB alone. The Ni-MOF/mKB14 composite (14 wt.% of mKB) demonstrated an overpotential of 294 mV at a current density of 10 mA cm−2 and a Tafel slope of 32 mV dec−1, which is comparable with commercial RuO2, commonly used as a benchmark material for OER. The catalytic performance of Ni(Fe)MOF/mKB14 (0.57 wt.% Fe) was further improved to an overpotential of 279 mV at a current density of 10 mA cm−2. The low Tafel slope of 25 mV dec−1 as well as a low reaction resistance due to the electrochemical impedance spectroscopy (EIS) measurement confirmed the excellent OER performance of the Ni(Fe)MOF/mKB14 composite. For practical applications, the Ni(Fe)MOF/mKB14 electrocatalyst was impregnated into commercial nickel foam (NF), where overpotentials of 247 and 291 mV at current densities of 10 and 50 mA cm−2, respectively, were realized. The activity was maintained for 30 h at the applied current density of 50 mA cm−2. More importantly, this work adds to the fundamental understanding of the in situ transformation of Ni(Fe)DMOF into OER-active α/β-Ni(OH)2, β/γ-NiOOH, and FeOOH with residual porosity inherited from the MOF structure, as seen by powder X-ray diffractometry and N2 sorption analysis. Benefitting from the porosity structure of the MOF precursor, the nickel-iron catalysts outperformed the solely Ni-based catalysts due to their synergistic effects and exhibited superior catalytic activity and long-term stability in OER. In addition, by introducing mKB as a conductive carbon additive in the MOF structure, a homogeneous conductive network was constructed to improve the electronic conductivity of the MOF/mKB composites. The electrocatalytic system consisting of earth-abundant Ni and Fe metals only is attractive for the development of efficient, practical, and economical energy conversion materials for efficient OER activity.

Research on biomimetic underwater vehicles for underwater ISR

Autonomous Biomimetic Underwater Vehicles BUVs driven by an undulating propulsion are a new branch in an area of an underwater robotics. They imitate both the construction and kinematics of a motion of underwater living organisms, e.g. fishes. Such vehicles have several features crucial from the point of view of military applications, e.g. larger secrecy and potential range of operation. The paper presents results of the research on BUVs carried out within two (Polish and EDA) projects both led by Polish Naval Academy. At the beginning, the initial efforts in building Polish BUV called CyberFish are included. Then, selected results of the tests of subsystems, e.g. navigational and 3D model of BUV built within national project are described. Next, the initial research achieved in the international project are showed. At the end, the schedule of the research planned to carry out within both projects is inserted. The paper is mainly focused on the hardware development of the BUVs.
The interacting influences of competition, composition and diversity determine successional community change

Community change is one of the few constants in nature, and the balance of mechanisms influencing this change is central for understanding the structure and functioning of communities and ecosystems. Newly established communities undergo succession and can change in diversity and composition as local environmental change, interspecific interactions and immigration play out over time. Understanding the influence of initial conditions and priority effects (long‐term consequences of the initial community composition and species identity) on community change is critically important for both evaluating ecological theory and predicting restoration outcomes. Here I evaluate how initial experimental conditions in 2012, like initial sown species richness, phylogenetic diversity and early biomass production, along with priority effects caused by the identity of sown species, influence subsequent herbaceous plant community composition and the number of colonizing species after 9 years of uninterrupted natural colonization. I found that sown phylogenetic diversity (measured as mean pairwise distance) indirectly affected the number of colonizing species by increasing biomass production early on and plots with more biomass in 2012 were colonized by fewer species. Individual species influenced the number of colonizing species with taller species reducing the number of colonists and some shorter species subject to a greater number of colonists. Synthesis. Taken together, these results indicate that initial composition influences the number of colonizing species via community‐wide competition. These findings suggest that restoration outcomes can be greatly influenced by decisions about sown species composition and early management practices.
Phytochemical Composition and Detection of Novel Bioactives in Anther Callus of Catharanthus roseus L.

Catharanthus roseus L. (G.) Don is the most widely studied plant because of its high pharmacological value. In vitro culture uses various plant parts such as leaves, nodes, internodes and roots for inducing callus and subsequent plant regeneration in C. roseus. However, till now, little work has been conducted on anther tissue using plant tissue culture techniques. Therefore, the aim of this work is to establish a protocol for in vitro induction of callus by utilizing anthers as explants in MS (Murashige and Skoog) medium fortified with different concentrations and combinations of PGRs. The best callusing medium contains high α-naphthalene acetic acid (NAA) and low kinetin (Kn) concentrations showing a callusing frequency of 86.6%. SEM–EDX analysis was carried out to compare the elemental distribution on the surfaces of anther and anther-derived calli, and the two were noted to be nearly identical in their elemental composition. Gas chromatography–mass spectrometry (GC–MS) analysis of methanol extracts of anther and anther-derived calli was conducted, which revealed the presence of a wide range of phytocompounds. Some of them are ajmalicine, vindolinine, coronaridine, squalene, pleiocarpamine, stigmasterol, etc. More importantly, about 17 compounds are exclusively present in anther-derived callus (not in anther) of Catharanthus. The ploidy status of anther-derived callus was examined via flow cytometry (FCM), and it was estimated to be 0.76 pg, showing the haploid nature of callus. The present work therefore represents an efficient way to produce high-value medicinal compounds from anther callus in a lesser period of time on a larger scale.
Drone photos process to estimate the common amount of trees in a given area by computer vision technologies

Many different goals can be served by processing digital photos, which is why there is such diversity in the subject of image processing. One of the foundations and essential tenets of computer vision is the image processing subfield, where basic operations like enhancing, cropping, and deleting unique characteristics are performed. You can use this method to determine the relative sizes of areas or objects in an image. We describe a study that makes use of cutting-edge computer vision techniques to investigate and assess palm tree plantations. Saladin, Iraqi date palm farms provide the data for this study. Trees are being mapped, analyzed, and categorized as well as cultivated and uncultivated land is being mapped. In the event of irrigation or tree-related calamities, the analysis can be used to exert control over these zones. According to the findings, our proposed method for identifying, analyzing, and classifying trees based on their crowns is superior.

Accounting for Cisnormativity: Understanding Transgender and Non-Binary Young People’s Strategies to Resist and Reduce Inequality in Healthcare

Using in-depth interviews with transgender and non-binary (TGNB) young adults in the Southeastern US, I examine TGNB young people’s healthcare experiences and strategies for resisting and reducing inequality in healthcare settings. My analysis draws on sociological conceptualizations of accountability structures in TGNB healthcare and specifically the conceptualization of cisnormative accountability. In this article, I demonstrate how TGNB patients are held accountable to the institutional and interpersonal maintenance of (a) cisnormativity and (b) the medical model of transgender identity in US healthcare systems. Such instances of cisnormative accountability, regardless of cisgender people’s intentions, contribute to the reproduction of gender inequality among TGNB communities. Further, I explain how TGNB young patients engage in strategies to resist and reduce inequality in healthcare through (a) avoidance of health services and (b) selective disclosure of TGNB identities. I draw out implications for understanding TGNB young people’s strategies to minimize inequality in healthcare, and the consequences cisnormative accountability has for the reproduction of gender inequality.
Tactile Sensor Structure Optimized for Sliding Motion With High Resolution Recording of Surface Topography

The demand for tactile devices with human-like exquisiteness has recently been increasing in various fields. Among the various parameters that humans feel through the tactile system, temperature and surface topography are the most important parameters to achieve artificial tactile devices with human level precision. Here, we present a new tactile sensor with high resolution surface topography recording and temperature measurement. Our tactile sensor was designed to have a surface topography sensing part driven by P(VDF-TrFE) and a thermistor part for temperature sensing. Even though the sensor touched the same temperature object, the sliding condition showed different resistance change values. Therefore, the correlation factors of the sliding velocity to temperature were defined with a simple relation function. To achieve high resolution recording, ‘zig-zag’ arrayed tactile sensor can overcome the limitations of simple matrix cell design. The design eliminates empty spaces between sensor cells. By using these systems, a resolution of $\sim 500\mu \text{m}$ to x-direction was achieved. This tactile sensor has linear sensitivity to pressure with a superior response time of 10ms for dynamic sensing. By integrating the dynamic piezoelectric signals during the sliding motion, we can reconstruct the surface topography of various objects.
Henipavirus Matrix Protein Employs a Non-Classical Nuclear Localization Signal Binding Mechanism

Nipah virus (NiV) and Hendra virus (HeV) are highly pathogenic species from the Henipavirus genus within the paramyxovirus family and are harbored by Pteropus Flying Fox species. Henipaviruses cause severe respiratory disease, neural symptoms, and encephalitis in various animals and humans, with human mortality rates exceeding 70% in some NiV outbreaks. The henipavirus matrix protein (M), which drives viral assembly and budding of the virion, also performs non-structural functions as a type I interferon antagonist. Interestingly, M also undergoes nuclear trafficking that mediates critical monoubiquitination for downstream cell sorting, membrane association, and budding processes. Based on the NiV and HeV M X-ray crystal structures and cell-based assays, M possesses a putative monopartite nuclear localization signal (NLS) (residues 82KRKKIR87; NLS1 HeV), positioned on an exposed flexible loop and typical of how many NLSs bind importin alpha (IMPα), and a putative bipartite NLS (244RR-10X-KRK258; NLS2 HeV), positioned within an α-helix that is far less typical. Here, we employed X-ray crystallography to determine the binding interface of these M NLSs and IMPα. The interaction of both NLS peptides with IMPα was established, with NLS1 binding the IMPα major binding site, and NLS2 binding as a non-classical NLS to the minor site. Co-immunoprecipitation (co-IP) and immunofluorescence assays (IFA) confirm the critical role of NLS2, and specifically K258. Additionally, localization studies demonstrated a supportive role for NLS1 in M nuclear localization. These studies provide additional insight into the critical mechanisms of M nucleocytoplasmic transport, the study of which can provide a greater understanding of viral pathogenesis and uncover a potential target for novel therapeutics for henipaviral diseases.
