Ultra-Thin SnS 2 -Pt Nanocatalyst for E ﬃ cient Hydrogen Evolution Reaction

: Transition-metal dichalcogenides (TMDs) materials have attracted much attention for hydrogen evolution reaction (HER) as a new catalyst, but they still have challenges in poor stability and high reaction over-potential. In this study, ultra-thin SnS 2 nanocatalysts were synthesized by simple hydrothermal method, and low load of Pt was added to form stable SnS 2 -Pt-3 (the content of platinum is 0.5 wt %). The synergistic e ﬀ ect between ultra-thin SnS 2 rich in active sites and individual dispersed Pt nanoclusters can signiﬁcantly reduce the reaction barrier and further accelerate HER reaction kinetics. Hence, SnS 2 -Pt-3 exhibits a low overpotential of 210 mV at the current density of 10 mA cm − 2 . It is worth noting that SnS 2 -Pt-3 has a small Tafel slope (126 mV dec − 1 ) in 0.5 M H 2 SO 4 , as well as stability. This work provides a new option for the application of TMDs materials in e ﬃ cient hydrogen evolution reaction. Moreover, this method can be easily extended to other catalysts with desired two-dimensional materials.
Risk-Based Distributionally Robust Optimal Gas-Power Flow With Wasserstein Distance

Gas-fired units and power-to-gas facilities provide pivotal backups for power systems with volatile renewable generations. The deepened system interdependence calls for elaborate consideration of network models of both natural gas and power systems, as well as uncertain factors. This paper proposes a data-driven distributionally robust optimization model for the optimal gas-power flow problem with uncertain wind generation. The concept of zonal line pack and line pack reserve are raised to topologically distinguish fuel suppliers of gas-fired units and ensure gas system operating security during reserve deployment. Wind power uncertainty is described by an ambiguity set, i.e., a family of candidate distributions around an empirical distribution in the sense of Wasserstein distance. A convex optimization-based solution procedure is developed, which entails solving only second-order cone programs. Computational results validate the effectiveness of the proposed models and methods.
ORIGINAL Prevalence rate of cytomegalovirus infection in individuals with and without systemic lupus erythematosus

Background: The role of cytomegalovirus (CMV) infection in triggering or exacerbating systemic lupus erythematosus (SLE) remains a subject of debate. The aim of this study was to compare the prevalence rate of CMV infection between individuals with and without SLE. Materials and Methods: This cross-sectional comparative study recruited 52 consecutive patients with SLE (based on the criteria determined by the Systemic Lupus Collaborating Clinics, 2012) and 52 healthy subjects. The exclusion criteria were immunodeficiency and other background diseases. CMV infection was assessed according to serology (enzyme-linked immunosorbent assay) and polymerase chain reaction (PCR). Results: Immunoglobulin G (IgG) was positive in all participants. Immunoglobulin M (IgM) was positive in eight SLE patients (15.4%) and none of the controls (p = 0.003). The PCR was positive in four SLE patients (7.7%) and none of the controls (p = 0.041). IgM level was not related to age, gender, literacy, marital status, family history, SLE disease activity index (SLEDAI), or duration of the disease (p > 0.05). Conclusion: According to this study, CMV infection was higher in SLE patients but was not related to the type of organ involvement, type of immunosuppressive drug, or SLEDAI.
Xyloglucan deficiency disrupts microtubule stability and cellulose biosynthesis in 16 Arabidopsis, altering cell growth and morphogenesis

Summary: We found that a mutant lacking xyloglucan in its cell walls has defects in cytoskeletal organization as well as cellulose organization and production, uncovering new links between wall structure, mechanics, and biosynthesis. ABSTRACT Xyloglucan constitutes most of the hemicellulose in eudicot primary cell walls and functions in cell 49 wall structure and mechanics. Although Arabidopsis thaliana xxt1 xxt2 mutants lacking detectable 50 xyloglucan are viable, they display growth defects that are suggestive of alterations in wall 51 integrity. To probe the mechanisms underlying these defects, we analyzed cellulose arrangement, 52 microtubule patterning and dynamics, microtubule- and wall integrity-related gene expression, 53 and cellulose biosynthesis in xxt1 xxt2 plants. We found that cellulose is highly aligned in xxt1 54 xxt2 cell walls, that its three-dimensional distribution is altered, and that microtubule patterning 55 and stability are aberrant in etiolated xxt1 xxt2 hypocotyls. We also found that the expression 56 levels of microtubule-associated genes such as MAP70-5 and CLASP , and receptor genes such 57 as HERK1 and WAK1 were changed in xxt1 xxt2 plants, and that cellulose synthase motility is 58 reduced in xxt1 xxt2 cells, corresponding with a reduction in cellulose content. Our results 59 indicate that loss of xyloglucan affects both the stability of the microtubule cytoskeleton and the 60 production and patterning of cellulose in primary cell walls. These findings establish new links 61 between wall integrity, cytoskeletal dynamics, and wall synthesis in the regulation of plant 62 morphogenesis. 63 xxt2 mutants and Col (wild type) controls using Atomic Force Microscopy (AFM), Field Emission We also generated transgenic Col and xxt1 xxt2 lines expressing GFP- MAP4 1998) and GFP-CESA3 (Desprez 2007), and analyzed MT arrays and cellulose synthesis using live-cell imaging. Our results show that the organization of CMFs is altered, that MTs in xxt1 xxt2 mutants are aberrantly organized and are more sensitive to external mechanical pressure and the MT-depolymerizing drug oryzalin, and that cellulose synthase motility and cellulose content are decreased in xxt1 xxt2 mutants. Furthermore, real-time quantitative RT-PCR measurements indicate that the enhanced sensitivity of cortical MTs to mechanical stress and oryzalin in xxt1 xxt2 plants might be due to altered expression of MT- stabilizing and wall receptor genes. Together, these data provide insights into the connections between the functions of XyG in wall assembly, the mechanical integrity of the cell wall, cytoskeleton-mediated cellular responses to deficiencies in wall biosynthesis, and cell and tissue morphogenesis.
Image Enhancement Background for High Damage Malay Manuscripts using Adaptive Threshold Binarization

Jawi Manuscripts handwritten which are kept at Malaysia National Library (MNL), has aged over decades. Regardless of the intensive sustainable process conducted by MNL, these manuscripts are still not maintained in good quality, and neither can easily be read nor better view. Even thought, many states of the art methods have developed for image enhancement, none of them can solve extremely bad quality manuscripts. The quality of old Malay Manuscripts can be categorize into three types, namely: the background image is uneven, image effects and image effects expand patch . The aim of this paper is to discuss the methods used to value add the quality of the manuscript. Our propose methods consist of several main methods, such as: Local Adaptive Equalization, Image Intensity Values, Automatic Threshold PP, and Adaptive Threshold Filtering. This paper is intend to achieve a better view image that geared to ease reading. Error Bit Phase achievement (TKB) has a smaller error value for proposed method (Adaptive Threshold Filtering Process / PAM) namely 0.0316 compared with Otsu’s Threshold Method / MNAO, Binary Threshold Value Method / MNAP, and Automatic Local Threshold Value Method / MNATA. The precision achievement (namely on ink bleed images) is using a proposed method more than 95% is compared with the state of the art methods MNAO, MNAP, MNATA and their performances are 75.82%, 90.68%, and 91.2% subsequently. However, this paper’s achievement is using a proposed method / PAM, MNAO, MNAP, and MNATA for correspondingly the image of ink bleed case are 45.74%, 54.80%, 53.23% and 46.02%. Conclusion, the proposed method produces a better character shape in comparison to other methods.
An Energy Efficient and Trusted Data Fusion by using Cellular Automata in Wireless Sensor Networks

—Wireless sensor networks are becoming more and more common. One of the limitations of wireless sensor nodes is their inherent limited energy resource. Besides maximizing the lifetime of the sensor node, it is preferable to increase the trust value of data fusion results. In this paper, a new protocol is introduced, named EETDFCA (an Energy Efficient and Trusted Data Fusion by using Cellular Automata) in Wireless sensor Networks. EETDFCA uses cellular automata rule to find the most suitable cluster head, perform data fusion, find the most trusted neighbors for sending the fusion result to base station, and transforms from current state to a new state. The network is intended for the long-term monitoring of packets produced by jammer nodes. The data flow of the network is mainly toward a cluster head node, which is responsible for collecting data generated by sensor nodes. When the network is first deployed, an initialization algorithm is performed and preliminary clusters, cluster heads and sensors alive are determined. Simulations and results show that the algorithm can extend the lifetime of the wireless sensor network and boost trusted data fusion frequency.
On the validity of Kraichnan scalings for forced two-dimensional turbulence

We examine the validity of the scaling laws derived by Kraichnan (1967) for forced two-dimensional turbulence. We use a new numerical technique (Dritschel & Fontane 2010) to reach higher Reynolds number than previously accessible with classical pseudo-spectral methods. No large scale friction or hypo-diffusion is used in order to avoid any distortion of the inverse cascade and to be in agreement with the theoretical framework used by Kraichnan. Both spectral and spatial forcing are considered and statistical convergence is obtained through large simulation ensembles. A steeper energy spectrum proportional to k^(-2) is observed for the inverse cascade in place of the classical k^(-5/3) prediction. This steepening is shown to be associated with a faster growth of energy at large scales, scaling like t^(-1) rather than Kraichnan's prediction of t^(-3/2). The deviation from Kraichnan's theory is related to the emergence of a vortex population dominating the distribution of energy across scales, and whose number density and vorticity distribution with respect to vortex area are related to the shape of the enstrophy spectrum.
REPLICATION STRATEGY USING HUFFMAN TREE LIKE STRUCTURE

— Replication strategy is mostly useful for replicating the mobile user’s profile at selected locations where some callers have higher calling rate. It plays important role in personal communication services (PCS) in order to reduce call setup time and increase the QoS. We have proposed a novel and innovative replication tree which is based on the Huffman tree and there is interrelationship between the replicated sites based on their effective replication probability. In the proposed scheme, the total network traffic statistic data of a mobile user is considered to define effective replication probability.

Robust state estimation of power systems based on equivalent measurement technique

The paper investigates the application of the equivalent measurement technique to the robust state estimation (SE) of power systems. In contrast to the weighted least square‐based SE method, the objective functions of the robust SE tend to suppress the influence of bad data contained in the measurement set during the estimation process. So there is no need to perform bad data elimination. In the proposed approach, the collected measured data, such as the power flowing through the transmission line, the injection power, and bus voltage magnitude, are converted into equivalent measurements as either current or voltage phasor quantities. Also the state variables are expressed in rectangular coordinates. This enables the relationship between the state variables and the measurements to be described by the linear measurement function and its Jacobian matrix is computed only once during the iterative solution computation. Some testing results of the standard IEEE test systems indicate that the proposed approach uses less computation time and still provides similar accuracy compared to the conventional SE. © 2017 Institute of Electrical Engineers of Japan.

Une méthode de sous-domaines pour la résolution des équations de Maxwell instationnaires en présence d'un ensemble non-connexe d'objets diffractant

A partir de l'etablissement d'une approximation in stationnaires en 3D des potentiels retardes pour des courants electromagnetiques sur des polyedres non-necessairement convexes, une methode de resolution pour la simulation de la diffraction par un ensemble non-connexe d'objets est formulee. Une partition de ce dernier est effectuee suivant les inhomogeneites presentes. Le probleme est alors traduit en un systeme d'equations de Maxwell couplees, chacune etant homogene hors d'un element correspondant de la partition, qui induit la construction d'une solution du probleme initial. Par approximation des termes de couplage, il s'en suit une methode naturellement hybride et parallele sur un systeme stable et bien-pose. La restriction de chaque sous-systeme a un voisinage du support de ses inhomogeneites est obtenue par introduction de conditions aux limites absorbantes de type "PML" dont un formalisme generalise est etudie. Des exemples numeriques illustrent l'ensemble de ces developpements.
Collision Avoidance for Predefined C-arm Trajectory using 3D Depth Measurements

—Human-robot collaborative act is obvious nowadays in a modern intervention room. It is very important to ensure the safety of the patient along with other personnel in the operation theater and prevent damages to the equipment during an intervention. Due to the complex environment and multiple unknown dynamic objects in the room, vision-based safety system has been regarded as a promising solution to the safety issue in such an environment in recent years. Moreover, the evolving pace of depth dense measuring by modern low-cost camera technologies has been fueling the scientific community to contribute to the healthcare applications. This work aims at developing a vision-based safety system in the intervention room to ensure collision-free trajectory of the C-arm integrated into the Philips Allura Xper X-ray Imaging device. The system is designed to accomplish the task of automatically identify the trajectory area of the C-arm in the room and then to avoid collisions in the identified area. The technique of locating trajectory area is realized by point cloud registration while the collision avoidance is ensured by detecting free-space in the area. The accuracy of the system has been evaluated for several practical cases. The collision avoidance algorithm showed accurate verdicts of declaring safe movements of the C-arm for all the cases while the automatic trajectory identification suffers from a drawback of correct registration, especially, due to the limited view frustum of the camera setup in the scene. The proposed system incorporates a prototype safety solution applicable to clinical setup.
Directed Secretion Immunological Synapse Formation and Distinct Roles of Cytoskeletal Components in

A hallmark of CD4 + T cell activation and immunological synapse (IS) formation is the migration of the microtubule organization center and associated organelles toward the APCs. In this study, we found that when murine CD4 + T cells were treated with a microtubule-destabilizing agent (vinblastine) after the formation of IS, the microtubule organization center dispersed and all of the major cellular organelles moved away from the IS. Cytokines were no longer directed toward the synapse but were randomly secreted in quantities similar to those seen in synaptic secretion. However, if the actin cytoskeleton was disrupted at the same time with cytochalasin D, the organelles did not shift away from the IS. These ﬁndings suggest that there is a complex interplay between the microtubules and actin cytoskeleton, where microtubules are important for directing particular cytokines into the synapse, but they are not involved in the amount of cytokines that are produced for at least 1 h after IS formation. In addition, we found that they play a critical role in mobilizing organelles to reorient toward the synapse during T cell activation and in stabilizing organelles against the force that is generated through actin polymerization so that they move toward the APCs. These ﬁndings show that there is a complex interplay between these major cytoskeletal components during synapse formation and maintenance. The Journal of Immunology , 2015, 195: 000–000. for 1 h before the addition of vinblastine or nocodazole. After incubation at 37˚C for an additional 3 h to allow cytokine production, cells were har-vested and adhered to polylysine-coated coverslips. They were then ﬁxed with 4% paraformaldehyde, permeabilized with 0.2% Triton X-100, and blocked in a blocking buffer (5% donkey serum in PBS). Primary and secondary Ab staining were performed in blocking buffer at room temperature for 30 min. After staining, coverslips were mounted on SuperFrost glass slides (Thermo Fisher Scientiﬁc, Waltham, MA) with Vectashield mounting medium (Vector Laboratories, Burlingame, CA). The primary Abs used in this study included rat anti–IL-2, rat anti–IFN- g , and anti– GM130-FITC Abs (BD Pharmingen, San Diego, CA). Donkey anti-rat FITC or donkey anti-rat Cy3 Abs (Jackson Immunoresearch, West Grove, PA) were used as the secondary Abs. Fixed cells were imaged using a Zeiss Axiovert S100TV microscope as described earlier. Data acquisition and analysis were conducted in MetaMorph 6.0 software (Universal Imaging). Forthe colocalization of Exo84 with centrosomes, T cells that were transduced with an Exo84-YFP construct were stained with a rabbit anti-pericentrin primary Ab (Covance, Princeton, NJ) and donkey anti-rabbit indocarbocyanine secondary Ab (Jackson Immunoresearch). T cell–CH27 cell conjugates were imaged with an LSM 510 confocal microscope with a 63 3 objective at the Cell Sciences Imaging Facility at Stanford University. Three-dimensional reconstructions were generated from the confocal z-stacks with the Velocity program (Improvision, Lexington, MA).
Troglitazone acts by PPAR (cid:1) and PPAR (cid:1) -independent pathways on LLC-PK 1 -F (cid:2) acid-base metabolism

Troglitazone acts by PPAR (cid:1) and PPAR (cid:1) -independent pathways on LLC-PK 1 -F (cid:2) acid-base metabolism. Am J Physiol Renal Physiol 286: F100–F110, 2004. 2003; 10.1152/ajprenal.00182. 2003. —Tro-glitazone was studied in pH-sensitive LLC-PK 1 -F (cid:2) cells to determine the effect on pH i and glutamine metabolism as well as the role of peroxisome proliferator-activated receptor (PPAR (cid:1) )-dependent and PPAR (cid:1) -independent signaling pathways. Troglitazone induces a dose-dependent cellular acidosis that occurs within 4 min and persists over 18 h as a result of inhibiting Na (cid:2) /H (cid:2) exchanger-mediated acid extrusion. Cellular acidosis was associated with glutamine-dependent augmented [ 15 N]ammonium production and decreased [ 15 N]alanine formation from 15 N-labeled glutamine. The shift in glutamine metabolism from alanine to ammoniagenesis appears within 3 h and is associated after 18 h with both a reduction in assayable alanine aminotransferase (ALT) activity as well as cellular acidosis. The relative contribution of troglitazone-induced cellular acidosis vs. the decrease in assayable ALT activity to alanine production could be demonstrated. The PPAR (cid:1) antagonist bisphenol A diglycide ether (BADGE) reversed both the troglitazone-induced cellular acidosis and ammoniagenesis but enhanced the troglitazone reduction of assayable ALT activity; BADGE also blocked troglitazone induction of peroxisome proliferator response element-driven ﬁreﬂy luciferase activity. The protein kinase C (PKC) inhibitor chelerythrine mimics troglitazone effects, whereas phorbol ester reverses the effects on ammoniagenesis consistent with troglitazone negatively regulating the DAG/ PKC/ERK pathway. Although functional PPAR (cid:1) signaling occurs in this cell line, the major troglitazone-induced acid-base responses appear to be mediated by pathway(s) involving PKC/ERK.
Novel Compound Heterozygous Variants in the CDC6 Gene in a Russian Patient with Meier-Gorlin Syndrome

Background: Meier-Gorlin syndrome (MGS) is a rare genetic syndrome inherited in an autosomal dominant or autosomal recessive manner. The disorder is characterized by bilateral microtia, absence or hypoplasia of the patella, and an intrauterine growth retardation as well as a number of other characteristic features. The cause of the disease is mutations in genes encoding proteins involved in the regulation of the cell cycle ( ORC1, ORC4, ORC6, CDT1, CDC6, GMNN, CDC45L, MCM3, MCM5, MCM7, GINS2 , and DONSON ). Meier-Gorlin syndrome 5 due to mutations in the CDC6 gene is difficult to diagnose, and few clinical data have been described to date. Only one patient (male) with a missense mutation in a homozygous state has been previously reported. This report describes a new clinical case of Meier-Gorlin syndrome 5. This is also the first report of a Russian patient with Meier-Gorlin syndrome. Case Presentation: The patient, a female, had extremely low physical development, neonatal progeroid appearance, lipodystrophy, thin skin, partial alopecia, cyanosis of the face, triangular face, microgenia, arachnodactyly, delayed bone age, hepatomegaly, hypoplasia of the labia majora, and hypertrophy of the clitoris in addition to known clinical signs. Differential diagnosis was performed with chromosomal abnormalities and Hutchinson-Gilford progeria. According to the results of sequencing of the clinical exome, the patient had two previously undescribed variants in the CDC6 gene, c.230A>G (p.(Lys77Arg)) and c.232C>T (p.(Gln78Ter)), NM_001254. 3, in a compound heterozygous state. Conclusion: This case allows us to learn more about the clinical features and nature of MGS 5 and improve the speed of diagnostics and quality of genetic counseling for such families.
ICT Services for Electro-Mobility

The evolution of mobility in a sustainable perspective requires specific attention to the end-users roles and the changing needs of the cities and policies. This work shows how ICT (Information and Communications Technology) services can allow the transition towards smart and sustainable mobility. Within the European project H2020 ELVITEN (GA nr. 769926), a proper set of ICT services are described, including: the brokering and the booking service for vehicles and charging stations, the ICT platform for monitoring the fleet of electric vehicles, the serious game app and a smart app for incentives. These services are suitable and indispensable to incentivize and encourage users towards a new mobility that is electric and sustainable.
