Arsenene and Antimonene: Two-Dimensional Materials with High Thermoelectric Figures of Merit

We study the thermoelectric properties of As and Sb monolayers (arsenene and antimonene) using density-functional theory and the semiclassical Boltzmann transport approach. The materials show large band gaps combined with low lattice thermal conductivities. Specifically, the small phonon frequencies and group velocities of antimonene lead to an excellent thermoelectric response at room temperature. We show that n-type doping enhances the figure of merit.
Hierarchical and Breathing Peer-to-Peer SIP System

The combination of the SIP-based service and peer-to-peer (P2P) can improve the performance of traditional client-server SIP system. However, current P2P SIP systems have many disadvantages. For example, node heterogeneity (e.g., bandwidth, CPU, storage and uptime) has not been considered enough which affects the scalability and service availability of P2P overlay; session setup latency is higher than that of traditional SIP system; and high cost is paid to maintain DHT overlays during a long idle uptime. In order to overcome these disadvantages, this paper proposes a novel hierarchical and breathing P2P SIP system. Its hierarchical overlay is composed of more than two suboverlays with different physical capability and system availability. Based on the hierarchical overlay, we propose a Node Virtualization Model that enables a node to share physical capability of powerful nodes in higher-level suboverlays. Suboverlays adopt breathing overlay model that enables a node to quit P2P overlay temporarily after a long idle uptime and rejoin P2P overlay when new SIP services are initiated on it. Based on the performance analysis and simulation results, our proposed system achieves better scalability and resource availability as well as shorter session setup latency, less bandwidth for DHT maintenance traffic and larger storage capacity than current P2P SIP systems.
Decentralized Neural Backstepping Control for an Industrial PA10-7CE Robot Arm

This paper presents a discrete-time decentralized control strategy for trajectory tracking of a seven degrees of freedom (DOF) robot arm. A high order neural network (HONN) is used to approximate a decentralized control law designed by the backstepping technique as applied to a block strict feedback form (BSFF). The neural network learning is performed online by extended Kalman filter. The local controller for each joint use only local angular position and velocity measurements. The feasibility of the proposed scheme is illustrated via simulation.
Muscle Activation During Grasping With and Without Motor Imagery in Healthy Volunteers and Patients After Stroke or With Parkinson's Disease

Introduction: The present study assessed whether motor imagery (MI) produces electromyographic activation in specific muscles of the upper limb during a hand grasping and arm-lifting task in healthy volunteers, patients after stroke, or with Parkinson's disease. Electromyographic (EMG) activation was compared under three conditions: MI, physical execution (PE), and rest. The task is clinically relevant unilateral executed movement using open muscle chains. Methods: In a cross-sectional study EMG activation was measured in four muscles: M. deltoideus pars clavicularis, M. biceps brachii, M. extensor digitorum, M. flexor carpi radialis. MI ability was evaluated with mental rotation, mental chronometry and the Kinaesthetic and Visual Imagery Questionnaire. Cognitive performance was screened with the Mini-Mental State Examination. Results: Twenty-two participants (11 females, age 52.6 ±15.8, age range 21 to 72) were included: ten healthy volunteers, seven patients after stroke (time after stroke onset 16.3 ± 24.8 months), and five patients with Parkinson's disease (disease duration 60.4 ± 24.5 months). Overall Mini-Mental State Examination scores ranged between 27 and 30. An increased EMG activation during MI compared to rest condition was observed in M. deltoideus pars clavicularis and M. biceps brachii across all participants (p-value = 0.001, p = 0.007). Seven participants (two healthy volunteers, three patients after stroke and two patients with Parkinson's disease) showed a EMG activation during MI of the hand grasping and arm-lifting task in at least one of the target muscles. No correlation between EMG activation during MI and scores of three MI ability assessments were found. Conclusions: The findings suggest that MI can yield subliminal EMG activation. However, that might vary on individual basis. It remains unclear what parameters contribute to or inhibit an EMG activation during MI. Future investigations should determine factors that influence EMG activation, e.g. MI instructions, tasks to imagine, amount of MI training, and longitudinal changes after an MI training period.

Storyboard-Based Empirical Modeling of Touch Interface Performance

Touch interactions are now ubiquitous, but few tools are available to help designers quickly prototype touch interfaces and predict their performance. For rapid prototyping, most applications only support visual design. For predictive modelling, tools such as CogTool generate performance predictions but do not represent touch actions natively and do not allow exploration of different usage contexts. To combine the benefits of rapid visual design tools with underlying predictive models, we developed the Storyboard Empirical Modelling tool (StEM) for exploring and predicting user performance with touch interfaces. StEM provides performance models for mainstream touch actions, based on a large corpus of realistic data. We evaluated StEM in an experiment and compared its predictions to empirical times for several scenarios. The study showed that our predictions are accurate (within 7% of empirical values on average), and that StEM correctly predicted differences between alternative designs. Our tool provides new capabilities for exploring and predicting touch performance, even in the early stages of design.
Bridgeless ZETA PFC converter for low voltage high current LED driver

This paper deals with power factor correction (PFC) in low voltage high current (LVHC) multi-string light emitting diode (LED) using a bridgeless (BL) ZETA. This application is designed for large area LED lighting with illumination control. A multi-mode LED dimming technique is used for lighting control. The BL-ZETA PFC converter feeds power to isolated flyback DC-DC converter. The regulated low voltage from flyback converter is a source power to the synchronous buck converters for multi-string LED driver and forced cooling system for LED junction. The BL-ZETA PFC converter inductor design is based on discontinuous inductor current modes (DICM) which provide good PFC at low cost. The proposed LED driver is designed and developed with hardware test results. The critical parameter of the LED driver is tested and measured at full load with dimming control capability for universal input AC (90–265 V). The total harmonic distortion (THD) is observed lesser than the IEC 61000-3-2 Class C harmonic limits.
A Tool to Analyze the Reading Behavior of the Users in a Mobile Digital Publishing Platform

In their daily activities, users interact multiple times with mobile applications. This generates huge amounts of data related to these interactions that, when filtered and analyzed, would give insights on the behavior of the users while using an application. In this paper, we consider a real-world mobile digital publishing platform, named Viewerplus, which enables a digital, augmented fruition of content from traditional magazines. The objective is to develop a tool that allows the human editors to analyze the reading behavior of the users, by providing analytics that show how the users read magazine issues (i.e., how they browse an issue and move inside the app, which portions of an issue are most frequently read and which frequency, and which topics are of interest for the users during a reading session). The tool has been developed by employing a dataset extracted from the reading sessions of a magazine of an important international publisher. In this work we also employ the dataset to present a preliminary study of the user reading behavior.
New phases of osmium carbide from evolutionary algorithm and ab initio computations

New crystal phases of osmium carbide are presented in this work. These results were found with the CA code, an evolutionary algorithm (EA) presented in a previous paper which takes full advantage of crystal symmetry by using an ad hoc search space and genetic operators. The new OsC2 and Os2C structures have a lower enthalpy than any known so far. Moreover, the layered pattern of OsC2 serves as a blueprint for building new crystals by adding or removing layers of carbon and/or osmium and generating many other Os + C structures like Os2C, OsC, OsC2 and OsC4. These again have a lower enthalpy than all the investigated structures, including those of the present work. The mechanical, vibrational and electronic properties are discussed as well.
A Scheduling Algorithm with Static Partition for Total Exchange

The GRID environment is a parallel or distributed system which utilizes geographically distributed computational resources, and has been receiving considerable attention over recent years. On the GRID environment, efficient scheduling algorithms for basic communication operations are important to improve total computational performance. In this paper, we consider improvement of scheduling algorithms for the total exchange, which is a basic communication pattern used on the GRID environment. We first prove that there exists an input which is hard to be scheduled without partition of communication events. We next propose a scheduling algorithm which consists of static partitions of the communication events. Finally, we compare performances between the proposed algorithm and other known algorithms for the total exchange using SimGrid. The experimental results show that our algorithm achieves performance improvements in comparison with previous algorithms for the input.
Real‐time imaging reveals defects of fast axonal transport induced by disorganization of intermediate filaments

Intermediate filament (IF) abnormalities frequently appear in neurodegenerative disorders, but how they may contribute to neuronal dysfunction remains unclear. Here, we examined the effects of IF disorganization on the fast axonal transport using timelapse microscopy. We studied the axonal transport of mitochondria and lysosomes in cultured primary dorsal root ganglion (DRG) neurons derived from mice deficient for neurofilament light (NFL–/–), mice overexpressing peripherin (Per), and mice double transgenic Per;NFL–/–. Unexpectedly, a net retrograde transport of mitochondria was detected in Per;NFL–/– neurons, opposite to the net anterograde transport of these organelles observed in wild‐type (Wt), NFL–/–, and Per neurons. A detailed analysis of the kinetic properties of mitochondrial movements revealed an increased frequency of retrograde movements and an increase of their velocity in Per;NFL–/– neurons compared to Wt, NFL–/–, and Per neurons. We also noticed that the depletion of axonal neurofilaments (NFs) in NFL–/– and Per;NFL–/– neurons induced longer and more persistent movements of mitochondria and lysosomes in both directions, which suggests that the NF network hampers the traffic of these organelles. The finding that an up regulation of peripherin in context of NFL deficiency can provoke a net retrograde transport of mitochondria is a phenomenon that may contribute to pathogenic changes in some neurodegenerative disorders with IF protein accumulations. —Perrot, R. , Julien, J.‐P.

Ross-Chernoff Glyphs Or: How Do We Kill Bad Ideas in Visualization?

As data increases in dimensionality or complexity, it becomes difficult to graphically represent data items or series in a straightforward way. Chernoff faces encode data values as features of a human face, but afford only a handful of dimensions, and can be difficult to decode. In this paper, we extend and improve Chernoff faces by merging them with the work of landscape painter Bob Ross, creating data-landscapes glyphs that directly encode data as three series with arbitrary numbers of data items per series. This is pretty obviously a bad idea, yet it is difficult to precisely articulate why, given the current state of the art in academic visualization. We propose and evaluate this technique as a way of highlighting these gaps in our ontology of bad visualization ideas, with the goal of being able to dismiss future bad ideas right out of the gate.
Dewetting transitions in protein cavities

In a previous analysis of the solvation of protein active sites, a drying transition was observed in the narrow hydrophobic binding cavity of Cox‐2. With the use of a crude metric that often seems able to discriminate those protein cavities that dry from those that do not, we made an extensive search of the PDB, and identified five other proteins that, in molecular dynamics simulations, undergo drying transitions in their active sites. Because such cavities need not desolvate before binding hydrophobic ligands they often exhibit very large binding affinities. This article gives evidence that drying in protein cavities is not unique to Cox‐2. Proteins 2010. © 2010 Wiley‐Liss, Inc.
Proactive detection of algorithmically generated malicious domains

Using an intrinsic feature of malicious domain name queries prior to their registration (perhaps due to clock drift), we devise a difference-based lightweight feature for malicious domain name detection. Using NXDomain query and response of a popular malware, we establish the effectiveness of our detector with 99% accuracy, and as early as more than 48 hours before they are registered. Our technique serves as a tool of detection where other techniques relying on entropy or domain generating algorithms reversing are impractical.
Real-time 360-degree video streaming over millimeter wave communication

This paper provides an adaptive scheme of real-time video streaming in millimeter wave (mmWave) system. It consists of two parts: (1) real-time video streaming over mmWave 802.11ad 60 GHz wireless link; (2) 360-degree video decoding, post-processing and displaying by using Scalable high-efficiency video coding (SHVC). The mmWave communication is high-speed wireless technology to increase the capacity of video transmission. However, the current video streaming over mmWave researches are for long-distance and mobile device almost processes many tasks such as video decoding, post processing and display by itself. Therefore, the performance of mobile device is quite low in case high-resolution video streaming like 4K. In addition, the synchronization of real-time video streaming in high speed is big issue to ensure the quality of service (QoS), especially when mobile device is moving. Thus, this paper focus on real-time video streaming over mmWave with optimized QoS for high-resolution video. Specifically, this paper implemented an offloading mechanism to handle the offloading task between two UEs. The experimental demonstration shows that the proposed scheme provided real-time video streaming with high performance in accepted QoS-sensitive video streaming applications.
The Fundamental and Application of Transient Flashing Spray Cooling in Laser Dermatology

Cryogen spray cooling (CSC) has been successfully implemented in laser dermatol- ogy such as the treatment of port wine stain. It can protect epidermis from irreversible thermal injuries and increase laser energy, leading to the improvement in therapeutic outcomes. Different from traditional steady spray cooling, CSC is highly transient with short spurt duration (several tens of milliseconds). Besides, CSC can achieve flashing atomization and fine droplets with simple structure nozzles by rapid release of super heat. In this chapter, the mechanism of CSC flashing spray, spray and thermal character - istics of droplets, the measurement method of transient temperature and algorithms for heat flux estimation, and the dynamic surface heat transfer and its relation with spray characteristics are fully discussed. Finally, the heat transfer enhancement of CSC is intro-duced including alternative cryogens, new nozzles, and hypobaric pressure method to increase the cooling ability, which is essential to improve therapeutic outcome, especially for darkly pigmented human skin.
Neurogenic Bladder

Congenital anomalies such as meningomyelocele and diseases/damage of the central, peripheral, or autonomic nervous systems may produce neurogenic bladder dysfunction, which untreated can result in progressive renal damage, adverse physical effects including decubiti and urinary tract infections, and psychological and social sequelae related to urinary incontinence. A comprehensive bladder-retraining program that incorporates appropriate education, training, medication, and surgical interventions can mitigate the adverse consequences of neurogenic bladder dysfunction and improve both quantity and quality of life. The goals of bladder retraining for neurogenic bladder dysfunction are prevention of urinary incontinence, urinary tract infections, detrusor overdistension, and progressive upper urinary tract damage due to chronic, excessive detrusor pressures. Understanding the physiology and pathophysiology of micturition is essential to select appropriate pharmacologic and surgical interventions to achieve these goals. Future perspectives on potential pharmacological, surgical, and regenerative medicine options for treating neurogenic bladder dysfunction are also presented.
Mediators between perfectionism and eating disorder psychopathology: shape and weight overvaluation and conditional goal-setting.

OBJECTIVE To examine mediators of the relationship between perfectionism and eating disorder (ED) psychopathology in a clinical sample. METHOD Participants were 201 women with a DSM-IV diagnosed ED consecutively referred to a specialist outpatient treatment clinic. Participants completed measures of perfectionism, ED psychopathology, shape and weight overvaluation, and conditional goal-setting (CGS). RESULTS Evaluation of a multivariate mediator model using Baron and Kenny's (1986) four-step mediation methodology showed that shape and weight overvaluation and CGS significantly and uniquely mediated the relation between self-oriented perfectionism (SOP) and restraint, eating concern, shape concern, and weight concern. The mediator model furthered the proportion of explained variance in outcomes beyond the direct effects model by 28-49%. DISCUSSION The findings support the conclusion that the relationship between SOP and ED psychopathology in women with a clinically diagnosed ED is mediated by shape and weight overvaluation and CGS.
Non-invasive electromagnetic wave sensor for flow measurement and biphase application / Oon Cheen Sean

Multiphase flow measurement is important in chemical processing, water treatment and oil & gas industry. The multiphase flow sensor proposed in this research utilizes the resonant frequencies that occur inside a cavity and the differences in the permittivity of the measures phases. By measuring this response over the range of discrete frequencies the sample can be characterised. Polar material like water has relatively high permittivity (er = 81), while non-polar material such as oil and gas have low permittivity value (er = 2.2-2.5) and (er = 1) respectively. Hence, a small change in the water fraction may result in a comparatively large frequency shift. In this research, the electromagnetic cylindrical cavity sensor system successfully demonstrated its capability to analyze various fractions of water-gas mixture. The results were consistent in the case of both the static and dynamic flow. The statistical analysis of the captured data showed a linear relationship of the amplitude data with the change in the water fractions. It was also found that the technique was independent of the temperature change. The system was able to successfully detect the stratified, wavy, elongated bubbles and homogeneous flow regimes. The electromagnetic rectangular cavity sensor system is introduced to pick up the tiny shifts in the permittivity when the low permittivity material is used or temperature changes. The microwave sensor system is able to detect water-air fraction, water-oil fraction, oil-air fraction and water temperature. The novel solution of the combination of both cylindrical and rectangular sensor system demonstrates the ability to detect both high and low permittivity changes. These dual-cavity sensor cavity systems have been able to detect water level, flow regime and temperature in the pipe. It also demonstrates that microwave sensors based on the principle of changing permittivity can replace conventional measurement techniques.
High-yield production of scutellaria radix flavonoids (baicalein, baicalin and wogonin) by liquid-culture of Scutellaria baicalensis root-derived cells

Production of baicalein, baicalin and wogonin by liquid culture of Scutellaria baicalensis cells derived from the plant root was studied. The maximum production obtained were 119 mg/L of baicalein at two week, 1372 mg/L of baicalin at eight week, and 14 mg/L of wogonin at two week. In addition, the production of baicalin was drastically increased to 1000 mg/L level at 3-week culture, and the extremely high production rate (339 mg/L•week) was obtained. In the comparison of total antioxidative activities among baicalein, baicalin and wogonin, evaluated by thiocyanate method, it was suggested that the location of hydroxyl groups both at 5- and 6-position contributed to enhancement of radical scavenging activity, and/or methoxylation at 8-position diminished the activity. The possibility of utilizing these flavonoids for natural antioxidants and medicine is also discussed.
