DETECTION OF TERNARY COMPLEX OF FIBRIN DESAB WITH D-DIMER AND D-FRAGMENT OF FIBRIN

The aim of this work is to study the intermolecular interactions of fibrin with D-domain-containing fragments of fibrin(ogen): D-dimer and D-fragment. Materials and methods. Human fibrinogen was obtained from the human blood plasma by salt extraction using 16 % Na2SO4. The content of protein coagulated by thrombin – 96-98%. Analytical size-exclusion chromatography for the detection of molecular complexes was performed on the Sepharose 6B column (30 x 0.5 cm). Components of the analyzed mixture (0.8 ml) were separated by standard chromatography protocol: speed of elution – 0.5 ml/min; collected samples volume – 0.5 ml. Optical density of collected samples was measured by spectrophotometer POP (Optizen, Daejeon, Korea). Composition of each sample was analyzed by SDS-PAGE. Relative amounts of studied compounds in samples were analyzed using densitometry of scanned electropherograms with Totallab TL100 software. Molecular modeling of complexes formed by fibrin desAB and its fragments were performed using UCSF Chimera 1.16 on the basis on earlier developed protofibril structure. The structure of the D-region (PDB ID:1LTJ) was prepared in the same in-protein molecular docking was performed using HDOCK web server. Results. To investigate the complex formation between fibrin desAB. The appearance of D- and DD-fragments in the elution zone of 5.5 mL, which does not overlap with the elution zone of individual fragments (7.5-9.5 mL), was detected, indicating the formation of a ternary complex. Densitometry of electropherograms using TotalLab TL-100 demonstrated that the average densities of pixels in bands of fibrin desAB, D-dimer and D-fragment were equal. It means that the ternary complex of fibrin desAB with D-dimer and D-fragment was composed in the approximate ratio of fibrin desAB, D-dimer and D-fragment 1:1:1. Molecular docking in the HDOCK software was used to establish the spatial arrangement of the D-fragment in relation to the fibrin desAB molecule bound to the D-dimer. Conclusions. We obtained and characterized the ternary complex of fibrin desAB, D-dimer and D-fragment by size-exclusion chromatography followed by SDS-PAGE. Further study of the structure and properties of this complex may clarify certain issues related to fibrin polymerization, namely the process of protofibril formation and their spatial branching.
Effective transport properties of composites with a doubly‐periodic array of fiber pairs and with a triangular array of fibers

This paper presents a complex variable solution for the effective transport properties of composites with a doubly‐periodic array of fiber pairs. By using the centrosymmetry of the problem, the method of Rayleigh and Natanzon‐Filshtinsky's approach can be simply extended to the problems with two fibers per unit cell. The infinite system constructed in this paper only slightly complicates Rayleigh's system for the problems with one fiber per unit cell. Approximate analytical formulae of the effective transport properties for different fiber‐pair arrays are obtained. The influence of pairwise interaction in fiber pairs on the effective transport properties is discussed in the numerical examples. As a special case of a doubly‐periodic array of fiber pairs, effective transport property of composites with a triangular array of fibers is obtained. The obtained approximate analytical formulae are written in a concise form with good accuracy, thus are convenient for engineering application in most cases, except for those approaching the limit case of percolation when the perfectly conducting fibers become touching. Besides the square array and hexagonal array, the triangular fiber array (similar to carbon atom arrangement in graphene) is another special symmetric fiber array which results into transversely isotropic effective property. Therefore, the present solution for the triangular array is an extension of those for the square array and hexagonal array. The comparison of the results for the three symmetric fiber arrays reveals that the triangular fiber array has the highest conductivity. In addition, accuracy of the present solution is analyzed in the numerical examples.

Comparison of extravasation events related to the peripheral administration of vasopressors prior to and following implementation of an institutional protocol

Following adequate fluid resuscitation, vasopressors are often utilized to maintain perfusion in shock states. Traditionally, vasopressors are administered via a central venous catheter (CVC) to attempt to minimize extravasation events. New literature advocates for peripheral vasopressor administration when CVC placement could lead to a delay in care. The purpose of this study was to compare extravasation events during vasopressor administration via a peripheral intravenous line (PIV) prior to and following the implementation of an institutional peripheral vasopressor protocol.
A Taxonomic Study on Pollen Morphology, Karyotype Features, Floral and Fruit Pigment Components of 13 Taxa of Lonicera L.

ABSTRACT Due to extensive introduction and breeding, the taxonomic relationships of Lonicera L. are unclear. Alternative scientific methods are needed to explore the classification of these new Lonicera. In this paper, the pollen morphology characteristics, karyotype features, and floral and fruit pigment components of 13 taxa of Lonicera were analyzed by means of scanning electron microscopy, karyotype analysis, High Performance Liquid Chromatography Mass Spectrometry (HPLC-MS) and Gas Chromatography-Mass Spectrometry (GC-MS). The 13 representatives of Lonicera were divided into groups of four, three, three and three taxa through the analysis of pollen morphology characteristics, karyotype features, floral composition and fruit pigment composition, respectively. Lonicera ruprechtiana and Lonicera tatarica always clustered together. Five hybrids, including Lonicera korolkow × Lonicera maackii and Lonicera korolkow × Lonicera tatarica No. 8 can generally be clustered with their parents. These results indicate that the analysis of pollen morphology characteristics, karyotype features, and floral and fruit pigment composition has value and significance for the study of systematic classification and relationships, and the conclusions of this study partially support morphological taxonomy.
A comparative CFD analysis of NACA0012 and NACA4412 airfoils

Wind energy has been seen as one of the most suitable sources of renewable energy. Wind energy is low cost when compared the other sources. Therefore, wind energy can gain an edge over the fossil-fired power plants. Aerodynamic efficiency of the airfoil is very crucial for aerodynamic efficiency of the wind turbine. The primary purpose of our study was to analyze the NACA0012 and NACA4412 airfoil at various attack angles with constant Reynolds number and to examine the effects of the symmetrical and asymmetrical profiles of the airfoil. Analysis of aerodynamic performance of NACA0012 and NACA4412 airfoil were performed with using ANSYS Fluent program. Also, lift coefficients and drag coefficients were calculated at various attack angles. According to calculations, optimum attack angles were found for each profile. Finally, NACA0012 and NACA4412 airfoils were discussed and reported in terms of their airfoil performances.
Reactive contaminant transport modeling using analytic element flow solutions

A new approach to modeling reactive contaminant transport in groundwater is developed and evaluated. The approach is unique in that it uses a gridor mesh-independent representation of model input parameters, including continuous velocities, dispersion coefficients, and saturated thickness values obtained directly from analytic element groundwater flow solutions. The approach is realized within a suite of revised finite element, finite difference, and characteristic methods that are designed to improve the accuracy and reduce the computational costs of complex reactive vertically-averaged transport simulations in surficial aquifers. These methods are implemented in a fully object-oriented parallel-friendly software framework, benchmarked against existing analytic and numerical solutions, tested against traditional discrete methods, and applied to a set of difficult field-scale test problems. It was found that the majority of the methods benefited from continuous representation, and that the use of the analytic element method can facilitate the development of computationally efficient multi-scale reactive transport models. Importantly, this work represents the first thorough implementation of a linkage between reactive contaminant transport models and the analytic element method for modeling groundwater flow, and the first detailed analysis of such a linkage.
High Electric Field Transport Characteristics in Field-Effect Transistors Based on Monolayer/Few-Layer MoS2

In recent years, the high electric field transport characteristics in field-effect transistors (FETs) based on monolayer/few-layer molybdenum disulfide (MoS2) have attracted much attention. However, as far as we know, there are no comprehensive and detailed reviews about the related investigations up to now. In this article, the recent advancements in numerical simulation and experimental investigation on the high electric field transport in monolayer/few-layer MoS2 FETs will be analyzed, respectively. Then, several promising research directions, which may further improve the high electric field transport characteristics, are expounded. In addition, some important parasitic effect at a high electric field in monolayer/few-layer MoS2 FETs, such as the self-heating effect, is introduced briefly. This article will provide meaningful guidance for the design of monolayer/few-layer MoS2 FETs with higher performance at high electric fields in the future.
The Structures of the Demersal Fish Communities of New Bedford and Gloucester Harbors, Two Massachusetts Urban Estuaries

Abstract - We sampled the inshore fish communities of New Bedford and Gloucester harbors synoptically using identical gear for 12 months during 1998–1999. Although the 2 harbors are only 110 km apart, they are separated by Cape Cod, which is the transition between the southern New England (New Bedford) and the Gulf of Maine (Gloucester) biogeographic regions. The 2 fish communities were 69% dissimilar from each other using the Bray–Curtis dissimilarity index (B–C). Stenotomus chrysops (Scup) composed 80% of the catch in New Bedford Harbor, did not occur in Gloucester Harbor, and contributed 7.40% to the total dissimilarity between the harbors. B–C identified 2 seasonal groups in the New Bedford Harbor fish community: May–October and November–April. Leucoraja spp. (skates) comprised the most numerous taxon captured in Gloucester Harbor, accounting for 24.90% of the total catch followed by Pseudopleuronectes americanus (Winter Flounder; 24.16%), and Gadus morhua (Atlantic Cod; 22.52%). These taxa contributed 7.23%, 3.88%, and 6.16% respectively to the total dissimilarity between harbors. B–C identified 4 seasonal groups in Gloucester Harbor: January, February and March, April and May, and June–December. These data provide an important description of the fish communities in the 2 harbors in different biogeographic regions at the end of the 20th century. We expect differences between the communities to decrease with increasing water temperature due to climate change.
Nonlinear Static and Dynamic Behavior of an Imperfect Circular Microplate Under Electrostatic Actuation

In this article, we investigate the nonlinear static and dynamic behavior of a clamped circular microplate in presence of imperfections. By taking in account the von Karman nonlinearity, the geometrical imperfections lead to a significant delay in static pull-in occurrence. Numerical simulations are performed in the frequency domain to study the dynamic behavior under primary resonance. A parametric analysis is conducted with respect to actuation voltages and initial deflection in order to capture the competition between hardening and softening behavior. Interestingly, we show that a geometric imperfection can change the type of nonlinear response from softening to hardening. In practice, the imperfection can be functionalized to enhance the performances of capacitive micromachined ultrasonic transducers.Copyright © 2017 by ASME
DoA estimation of highly correlated stochastic sources using neural model

ABSTRACT MultiLayer perceptron (MLP)-based neural model for an efficient 1D DoA estimation of highly correlated stochastic EM sources is proposed. Model extracts this information from a spatial correlation matrix obtained by sampling stochastic signals by a receiving antenna array. Algorithm for optimal selection of correlation matrix elements from the upper triangle of the matrix is suggested to reduce the number of antenna array elements needed to obtain an accurate neural model with relatively simple architecture. This approach is verified by determining the azimuth position of two sources with the mutual correlation in the range [0.8–0.95] using antenna arrays with different number of elements.
Person Marking in Stau

Author(s): Jacques, Guillaume; Antonov, Anton; Yunfan, Lai; Nima, Lobsang | Abstract: This paper offers an overview of the verb system and person marking in a hitherto poorly described Sino-Tibetan language. We posit the existence of six verb classes based upon alternations of the final stem vowel, both for transitive and intransitive verbs. Person marking is described in comparison with that of closely related Rgyalrongic languages is found to be of interest for the reconstruction of the protosystem. The data analysed show that Rtau is also interesting from a typological point of view as it illustrates of a hitherto undescribed subtype of hierachical agreement.
Stability Properties of Large-scale Baroclinic Disturbances in a Vertically and Horizontally Variable Zonal Current

The changes of energies of the mean flow with the vertical and horizontal shears and a superimposed disturbance are discussed, using the quasigeostrophic vorticity equation. Stability properties of the simple baroclinic atmosphere which is made up from the northern hemispheric" data after Starr and White (1954) are investigated by means of the so-called "energy method ". The direction of the energy flow is examined for various ranges of the disturbance wave length. It is found that amounts of increase of the kinetic energy of the mean flow due to non-linear interaction seem to be sufficient to overcome those which are continuously exhausted within the friction layer near the ground. The unstable baroclinic disturbance tends to produce the poleward and upward transport of sensible heat, and simultaneously the intensity of the zonal current is strengthened by concentration of eddy zonal momentum due to the presence of the latitudinal variation of the mean flow.
Perceived Efficacy in Initiating Romantic Relationships and Single Emerging Adults’ Well-Being

Using data from 313 single emerging adults living in the United States, we explored initiation-efficacy (i.e., perceived abilities related to initiating romantic relationships) and if it was associated with well-being (life satisfaction, happiness with romantic experiences, and loneliness). Most participants indicated that it is not easy to ask someone out or tell someone they are interested in them and talking with someone they have feelings for is awkward. Initiation-efficacy was associated with well-being. Specifically, reporting that it is easy to ask someone out on a date was associated with greater life satisfaction and happiness with romantic experiences, but less loneliness. Further, emerging adults were lonelier when talking to someone they have feelings for was awkward. Finally, neither relationship desire or dismissal moderated associations between initiation-efficacy and well-being. However, relationship dismissal was associated with greater life satisfaction and happiness with romantic experiences and relationship desire was associated with more loneliness.

The main idea in searching for algorithm is to regenerate new samples around each solution with a Guassian distribution. Numerical simulations have revealed that the new presented algorithm outperformed some evolutionary algorithms.
Back Propagation Artificial Neural Network Based DC Bus Capacitance Identification Method in Three-Phase PWM Rectifier for Charging System of EVs

In order to improve the performance and reliability of the three-phase PWM rectifier in electric vehicle charging system, it is important to focus on the identification of the dc bus capacitance. The existing methods have the disadvantages such as a low identification accuracy, a high hardware dependency, and high costs. Therefore, the development of new identification methodologies could be the way out of the aforementioned disadvantages, in terms of advanced algorithms. In this article, a dc-bus capacitance identification method based on back propagation (BP) artificial neural network (ANN) algorithm is proposed. The capacitance can be accurately identified in the diode rectification stage, by training the neural network to extract the potential laws in the data, which only includes the phase-a voltage and current, as well as the dc bus voltage ripple. The regression response is 0.99991. Finally, the experimental results show the accuracy and effectiveness of the proposed method. A simple and effective BP ANN is designed, and it can identify the capacitance at different grid voltages and dc bus loads. It has a high identification accuracy that the maximum identification error is less than 4.5%.

State Disaggregation for Dynamic Scaling of Network Functions

Network Function Virtualization promises better utilization of computational resources by dynamically scaling resources on demand. However, most network functions (NFs) are stateful and require state updates on a per-packet basis. During a scaling operation, cores need to synchronize access to a shared state to avoid race conditions and to guarantee that NFs process packets in arrival order. Unfortunately, the classic approach to control concurrent access to a shared state with locks does not scale to today’s throughput and latency requirements. Moreover, network traffic is highly skewed, leading to load imbalances in systems that use only sharding to partition the NF states. To address these challenges, we present Dyssect, a system that enables dynamic scaling of stateful NFs by disaggregating the states of network functions. By carefully coordinating actions between cores and a central controller, Dyssect migrates shards and flows between cores for load balancing or traffic prioritization without resorting to locks or reordering packets. Also, Dyssect’s state disaggregation allows the offloading of stateful network functions to programmable NICs and makes it easier for exploring hardware-software tradeoffs that better suit specific service chains and traffic loads. Our experimental evaluation shows that Dyssect reduces tail latency up to 32.04% and increases throughput up to 19.36% when compared to state-of-the-art competing solutions.
Fourier-Based Vibration Model of Electrical Machines Considering Nonideal Orthogonality Between Electromagnetic Forces and Structural Modes

This article proposes a Fourier-based model of vibration synthesis, improving both precision and speed. For the first time, the nonideal orthogonality between electromagnetic (EM) forces and structural modes is theoretically proposed and modeled by spatial harmonics. Different from the discrete vectors used in the previous literature, the proposed method achieves a one-dimension continuous model of EM forces and modes. On the basis, the vectors of modes and forces on tooth surfaces are decomposed by fast Fourier transform, so that the vibration response is synthesized based on Fourier coefficients. Furthermore, the proposed model is applied to a 12-slot/10-pole interior permanent-magnet machine. The spatial harmonics of mode vectors are elaborated to identify the key orders of EM forces before the vibration response is completed. Then, the proposed model is compared with the coupled-field finite element analysis (FEA). The advantages are verified in terms of computational accuracy, speed, and sensitivity to mesh quality. Finally, the feasibility of the proposed model is verified by both coupled-field FEA and experiment.
