The Effect of Volition on the Stability of Bimanual Coordination

Abstract The authors investigated how the intention to passively perform a behavior and the intention to persist with a behavior impact upon the spatial and temporal properties of bimanual coordination. Participants (N = 30) were asked to perform a bimanual coordination task that demanded the continuous rhythmic extension-flexion of the wrists. The frequency of movement was scaled by an auditory metronome beat from 1.5 Hz, increasing to 3.25 Hz in 25-Hz increments. The task was further defined by the requirement that the movements be performed initially in a prescribed pattern of coordination (in-phase or antiphase) while the participants assumed one of two different intentional states: stay with the prescribed pattern should it become unstable or do not intervene should the pattern begin to change. Transitions away from the initially prescribed pattern were observed only in trials conducted in the antiphase mode of coordination. The time at which the antiphase pattern of coordination became unstable was not found to be influenced by the intentional state. In addition, the do-not-intervene set led to a switch to an in-phase pattern of coordination whereas the stay set led to phase wandering. Those findings are discussed within the framework of a dynamic account of bimanual coordination.
Propagation of longitudinal leaky surface waves under periodic metal grating structure on lithium tetraborate

The dispersion properties of longitudinal leaky surface waves propagating under the periodic Al strip grating on lithium tetraborate (Li/sub 2/B/sub 4/O/sub 7/; LBO) are described theoretically and experimentally for applications of the mode to high frequency SAW devices. A theoretical method developed here is based on Floquet's theorem using space harmonics as an orthogonal function set and real boundary integral equations derived from the method of weighted residuals for a period of each region, i.e., substrate, metal, and free space. The boundary integral equations are solved by using the Galerkin procedure. The periodic strip gratings with both single-electrodes and double-electrodes are investigated, considering the convergency of the numerical computation for the number of the space harmonics. As a result, the propagation loss for shorted gratings was found to be relatively low in the thickness range of the Al strip below about 1% for the single-electrodes and 2% for the double-electrodes, although it greatly increases for a thickness over 2% for the single-electrodes and 3% for the double-electrodes.
Assessing the Usability of the Hart InterCivic eSlate During the 2016 Presidential Election

For the first time, the system usability of the eSlate–one of the most ubiquitous electronic voting machines used in US elections–was assessed in the field on election day 2016 using ISO 9241-11 metrics. Effectiveness and satisfaction measures were collected immediately after voters used the eSlate to vote at their assigned polling location. The findings showed that the perceived usability of the system in the polling station was judged to be quite good, despite previous research that indicated usability difficulties with the voting system. It is hypothesized that voters were making retrospective assessments of not just the eSlate, but also the supporting systems and environment in which they used it on election day. In particular, voters were likely taking into account their entire experience—including the help of poll workers and circumstances like short lines—versus just their experience with the machine itself. Practitioners and researchers should be aware that a system might not be completely usable but still be subjectively rated as usable due in part to other supporting systems and environmental variables.
Crystallographically driven magnetic behaviour of arrays of monocrystalline Co nanowires

Cobalt nanowires, 40 nm in diameter and several micrometers long, have been grown by controlled electrodeposition into ordered anodic alumina templates. The hcp crystal symmetry is tuned by a suitable choice of the electrolyte pH (between 3.5 and 6.0) during growth. Systematic high resolution transmission electron microscopy imaging and analysis of the electron diffraction patterns reveals a dependence of crystal orientation from electrolyte pH. The tailored modification of the crystalline signature results in the reorientation of the magnetocrystalline anisotropy and increasing experimental coercivity and squareness with decreasing polar angle of the ‘c’ growth axis. Micromagnetic modeling of the demagnetization process and its angular dependence is in agreement with the experiment and allows us to establish the change in the character of the magnetization reversal: from quasi-curling to vortex domain wall propagation modes when the crystal ‘c’ axis tilts more than 75° in respect to the nanowire axis.
Robust helical path separation for thickness mapping of pipes by guided wave tomography

Pipe wall loss caused by corrosion can be quantified across an area by transmitting guided Lamb waves through the region and measuring the resulting signals. Typically the dispersive relationship for these waves, which means that wave velocity is a known function of thickness, is exploited, enabling the wall thickness to be determined from a velocity reconstruction. The accuracy and quality of this reconstruction is commonly limited by the angle of view available from the transducer arrays. These arrays are often attached as a pair of ring arrays on either side of the inspected region, and due to the cylindrical nature of the pipe, waves are able to travel in an infinite number of helical paths between any two transducers. The first arrivals can be separated relatively easily by time gating, but by using just these components the angle of view is severely restricted. To improve the viewing angle, it is necessary to separate the wavepackets. This paper provides an outline of a separation approach: initially the waves are backpropagated to their source to align the different signals, then a filtering technique is applied to select the desired components. The technique is applied to experimental data and demonstrated to robustly separate the signals.
Social Support and Motherhood

Drawing on vast experience as an academic researcher and writer, the author develops a sociology of the research process itself, telling the story of how a research project is undertaken and what happens during it, to both researchers and those who are researched. The book focuses on a topic of great importance in the provision of health services — caring and social support. Setting neglect of this topic in the wider context of an ongoing crisis in gendering knowledge, this book is now reissued for a contemporary audience. It has much resonance for social science researchers and others interested in the experiences of mothers, and in the relations between social research, academic knowledge and public policy.
The effect of service staff’s verbalized hospitality towards group diner’s additional purchases and tipping behaviour

ABSTRACT Verbal communication is the main form of personal interaction. This article presents evidence for the positive role of service staff’s verbalized hospitality on consumer behaviour. The principal aim of the study was to explore the effect of verbal attention on making additional purchases and tipping behaviour in three different countries (Sweden, England, and Serbia). Moreover, research investigated whether server gender, customer gender, and group size moderate the relationship between verbal attention, additional purchase, and tipping behaviour. For the purpose of the study, servers in casual dining restaurants either paid special verbal attention to group diners, or did not do so, before asking target questions. The results show that group diners in verbal attention conditions make additional purchases and leave tips more often. While group size moderates the relationship between verbal attention and additional purchase and tipping behaviour, such role was not confirmed in the case of server gender and customer gender. The theoretical and practical implications of verbal interaction between servers and customers are discussed, as well as differences in three analysed countries.

In this paper Capacitively-Loaded Loop (CLL) metamaterial structures are applied to a Bi-Yagi antenna in order to improve its overall performance. Preliminary results show that the new antenna can be designed with an improvement of 13.48 dB on the reflection parameter, 0.37 dB on the gain, followed by a reduction of 11% on its area, when compared to the conventional Bi-Yagi antenna found in the literature.

Above all, we wish to thank the sex workers who participated in the training and personal interviews. Without their stories, this work would not have been possible.
A fuzzy based method for developing fault tolerance in mobile sensor network

Faults occurring to sensor nodes are common due to the sensors limitations and the harsh environment sensor networks. The fault sensors lowest effect in network efficiency or in others word sensor network has fault tolerance. In this paper is studied the fault tolerance problem from the coverage point of view for sensor networks. In the proposed methods missing regions with faulty sensors recoup by its neighbors and using minimum redundant sensors. After, a sensor node becomes fault, coverage loss caused covered by its neighbors moving to failure node. Major problem elected neighbor node for movement, the priority of neighbor nodes for movement and coverage missing regions determines overlapping sensing range and its distance from faulty node. In purposed method priority of neighbors determine by fuzzy logic. The purposed fuzzy system has two inputs overlapping and distance, and its output is priority of neighbors. The target of proposed method is decrement redundant sensors for replacement faulty sensors in network sensor. The propose method compared with previous methods which used only from redundant sensors. The comparison show purposed method improved number redundant sensor used and movement sensors.
Real Time Density-Based Clustering (RTDBC) Algorithm for Big Data

Density Based Spatial Clustering of Applications with Noise (DBSCAN), a well-known Density-Based Clustering Algorithm is a advanced data clustering method with various applications in numerous fields like Satellites images, X-ray crystallography, Anomaly Detection in Temperature Data. But its run time R(n2) complexity draws a major challenge. In this research paper, we propose a new unique algorithm called Real Time Density Based Clustering RTDBC to minimize the problems in DBSCAN. In proposed algorithms, objects are allotted into clusters using labels representatives than the method of propagating directly to reduce propagation time of label considerably. In contrast, RTDBC produce fast result and continuous process of runtime and additionally users are permitted to suspend for testing the result and continue as to enhance good results.
The Pace of Change and Creative Performance: Specialist and Generalist Mathematicians at the Fall of the Soviet Union

Past research is divided on whether specialists or generalists have superior creative performance. While many have highlighted generalists’ advantage due to access to a wider set of knowledge components, others have underlined the benefits that specialists can derive from their deep expertise. We argue that this disagreement might be partly driven by the fact that the pace of change in a knowledge domain shapes the relative return from being a specialist or a generalist. Using the impact of the Soviet Union’s collapse on the performance of theoretical mathematicians as a natural experiment, we show that generalist scientists performed best when the pace of change was slower, but that specialists gained advantage when the pace of change increased. We discuss and test the roles of cognitive mechanisms and of competition for scarce resources. Overall, our results highlight important trade-offs associated with specialization for creative performance.
The P300 to novel and target events: a spatio–temporal dipole model analysis

It has been reported that frontal lobe structures are critical for the generation of P300 activity in the human event-related potential (ERP) evoked by novel events. In this study spatial–temporal dipole model analyses were employed to obtain further evidence on the temporal dynamics and the approximate location of neuronal activity involved in P300 generation for target and novel events. A triple dipole configuration was found to describe the scalp recorded P300 activity for novel and target events with less than 2.5% residual variance. For the novel, but not the target dipole configuration a frontally oriented dipole was obtained whose temporal activity function suggests that the brain areas involved in the processing of novel events are engaged about 70 ms earlier than those relevant for target processing.
Influence of Rest Interval Length on Acute Testosterone and Cortisol Responses to Volume-Load–Equated Total Body Hypertrophic and Strength Protocols

Abstract Villanueva, MG, Villanueva, MG, Lane, CJ, and Schroeder, ET. Influence of rest interval length on acute testosterone and cortisol responses to volume-load–equated total body hypertrophic and strength protocols. J Strength Cond Res 26(10):2755–2764, 2012—We hypothesized that total body strength (S) and hypertrophic (H) resistance training (RT) protocols using relatively short rest interval (RI) lengths between sets will elicit significant acute increases in total testosterone (TT) and cortisol (C) in healthy young men. Six men, 26 (±2.4) years, completed 4 randomized RT sessions, after a control session (R). The S and H protocols were equated for volume load (sets × repetitions × load); S: 8 sets × 3 repetitions at 85% 1RM, H: 3 sets × 10 repetitions at 70% 1RM, for all exercises. The RI used 60 seconds (S60, H60) and 90 seconds (S90, H90). Blood was drawn preexercise (PRE), immediately postexercise (POST), 15 minutes postexercise (15 MIN), and 30 minutes postexercise (30 MIN). The H60 elicited significant increases in TT from PRE (7.32 ± 1.85 ng·ml−1) to POST (8.87 ± 1.83 ng·ml−1) (p < 0.01), 15 MIN (8.58 ± 2.15 ng·ml−1) (p < 0.01), and 30 MIN (8.28 ± 2.16 ng·ml−1) (p < 0.05). The H90 also elicited significant increases in TT from PRE (8.37 ± 1.93 ng·ml−1) to POST (9.90 ± 1.25 ng·ml−1) (p < 0.01) and 15 MIN (9.46 ± 1.27 ng·ml−1) (p < 0.05). The S60 elicited significant increases in TT from PRE (7.73 ± 1.88 ng·ml−1) to 15 MIN (8.35 ± 1.64 ng·ml−1) (p < 0.05), and S90 showed a notable (p < 0.10) difference in TT from PRE (7.96 ± 2.29 ng·ml−1) to POST (8.75 ± 2.45 ng·ml−1). All the protocols did not significantly increase C (p > 0.05). Using relatively short RI between RT sets augments the acute TT response to hypertrophic and strength schemes. Shortening RI within high-intensity strength RT may lead to concomitant enhancements in muscle strength and size over a longer period of training.
Parametric solutions to rectangular high-order sylvester equations—Case of F Jordan

In an recent paper, we have proposed a general complete parametric solution in a simple and neat analytical closed form to a type of rectangular high-order Sylvester matrix equations with the parameter matrix F being an arbitrary matrix. Based on this result, in this paper we are presenting, for a type of rectangular high-order Sylvester matrix equations with the parameter matrix F being in a Jordan matrix form, a complete parametric solution which is expressed in terms of a free parameter matrix Z representing the degrees of freedom. The primary feature of this solution is that the matrix F, together with the parameter matrix R, does not need to be even known a priori, and thus may be set undetermined and used as degrees of freedom beyond the completely free parameter matrix Z. The results provide great convenience to the computation and analysis of the solutions to this class of equations, and can perform important functions in many control systems analysis and design problems involving high-order dynamical systems.
Off-line writer identification using multi-scale local binary patterns and SR-KDA

Writer identification is becoming an increasingly important research topic especially in forensic and biometric applications. This paper presents a novel method for performing offline write identification by using multi-scale local binary patterns histogram (MLBPH) features. The proposed feature (MLBPH) when combined with edge-hinge based feature achieves a top 1 recognition rate of 92% on the benchmark IAM English handwriting dataset, outperforming current state of the art features. Further, kernel discriminant analysis using spectral regression (SR-KDA) is introduced as dimensionality reduction technique to avoid the overfitting problem associated with using multi-scale data.
Colonic migrating motor complexes (CMMCs) in the isolated mouse colon

Spontaneous contractions were recorded from the circular muscle layer at three sites along the isolated mouse colon. The interval between contractions was ≈ 4.5 min. The mean duration of the contractions ranged from 26 sec in the distal colon to 45 sec in the proximal colon. Contractions migrating more than half the length of the colon were termed colonic migrating motor complexes (CMMCs). Over 90% of tissues demonstrated migration predominantly in an aboral direction. Hyoscine (10−6 m) decreased the amplitude of the CMMCs by at least 40% but had no significant effect on the interval or duration of the CMMCs. Nifedipine (10−6 m) significantly decreased the amplitude of the CMMCs by 95% but did not alter the duration or the interval between the CMMCs. Hexamethonium (5 × 10−4 m) and tetrodotoxin (TTX; 2 × 10−6 m) abolished all CMMC activity. TTX increased the resting tone of the preparations. Nitro‐L‐arginine (10−4 m) increased the resting tone of the preparations and significantly decreased the interval between the CMMCs by ≈ 80% but had no significant effect on the duration of the CMMCs. The results suggest CMMCs migrate predominantly in an aboral direction and are neurogenic in origin. Nitric oxide may be involved in maintaining inhibition of the muscle between CMMCs.
Branched-chain amino acids complex inhibits melanogenesis in B16F0 melanoma cells

Present study was investigated the effect of each or complex of three branched-chain amino acids (BCAAs; isoleucine, leucine, and valine) on melanin production in B16F0 melanoma cells treated with various concentrations (1-16 mM) for 72 h. Among the 20 amino acids, lysine and glycine showed the highest activities of DPPH radical scavenging and mushroom tyrosinase inhibition, respectively. Each and combination of BCAAs reduced melanogenesis in a concentration-dependent manner without any morphological changes and cell viability in melanoma cells. Present study was also investigated the inhibitory effects of each or complex of BCAAs at each 10 mM concentration on the 100 μM IBMX-mediated stimulation of melanogenesis in melanoma cells for 72 h and found that IBMX treatment was stimulated to enhance melanin synthesis and that the complex of BCAAs was the most effectively inhibited in the melanin amounts of cellular and extracellular and the whitening the cell pellet. When the inhibitory effect of BCAAs on tyrosinase was examined by intracellular tyrosinase assay, both isoleucine and valine exhibit slightly inhibition, but leucine and combination of BCAAs did not inhibit the cell-derived tyrosinase activity. Present study demonstrated that complex of BCAAs inhibited melanin production without changes intercellular tyrosinase activity. Thus, the complex of BCAAs may be used in development of safe potentially depigmenting agents.
Quantum-Dot-Based Aptamer Beacons for  ${\rm K}^{+}$ Detection

Herein, aptamer-based quantum-dot detectors of K+ made of two-different K+ aptamers are compared. These deoxyribonucleic acid-based aptamers are TBA (5' GGT TGG TGT GGT TGG 3') and AG3 ( 5' GGG TTA GGG TTA GGG TTA GGG 3' ). The nanoscale aptamer-quantum-dot-based detectors described in this paper are synthesized and tested in DI water aliquots that contain KCl. The results including data suggest that beacons made of AG3 and TBA serve better as an ion indicator in different potassium level regions. As a result, aptamer beacon made of AG3 has better potential in the design of take-home diagnostic devices for hyperkalemia and hypokalemia.
Association of p59 fyn with the T Lymphocyte Costimulatory Receptor CD2

Human CD2 is a 50–55-kDa cell surface receptor specifically expressed on the surface of T lymphocytes and NK cells. Stimulation of human peripheral blood T cells with mitogenic pairs of anti-CD2 monoclonal antibodies (mAbs) is sufficient to induce interleukin-2 production and T cell proliferation in the absence of an antigen-specific signal through the T cell receptor. CD2 has been shown previously to associate physically with the Src family protein-tyrosine kinases p56 lck and p59 fyn . We now report that stimulation of T cells with mitogenic pairs of anti-CD2 mAbs enhanced the association of the Fyn polypeptide with the CD2 complex, whereas stimulation with single anti-CD2 mAb had minimal effect. Using glutathione S-transferase (GST) fusion proteins, we found that CD2 bound to the Src homology (SH) 3 domain of Fyn. Interestingly, the CD2-Fyn association was negatively regulated by the Fyn SH2 domain; CD2 bound poorly to GST fusion proteins expressing both the SH2 and SH3 domains of Fyn. However, the inhibitory effect of the Fyn SH2 domain on binding of the Fyn SH3 domain to CD2 was relieved by peptides containing a phosphorylated YEEI sequence that bound directly to the Fyn SH2 domain. In addition, we found that the ability of the Fyn SH2 domain to precipitate tyrosine-phosphorylated proteins, including the CD3ζ chain, was enhanced after T cell stimulation with mitogenic pairs of CD2 mAbs. Finally, overexpression of a mutated Fyn molecule, in which the ability of the Fyn SH2 domain to bind phosphotyrosine-containing proteins was abrogated, inhibited CD2-induced transcriptional activation of the nuclear factor of activated T cells (NFAT), suggesting a functional involvement of the Fyn SH2 domain in CD2-induced T cell signaling. We thus propose that stimulation through the CD2 receptor leads to the tyrosine phosphorylation of intracellular proteins, including CD3ζ itself, which in turn bind to the Fyn-SH2 domain, allowing the direct association of the Fyn SH3 domain with CD2 and the initiation of downstream signaling events.
The complete mitochondrial genome of Liobagrus marginatus (Teleostei, Siluriformes: Amblycipitidae)

Abstract The Liobagrus marginatus is an economic fish which distribute in the upstream of Yangtze river and its distributary. For its taste fresh, environmental pollution and overfishing, its population declined drastically and body miniaturization in recent decades, so it is essential to protect its resource. In this study, the complete mitochondrial genome sequence of Liobagrus marginatus was sequenced, which contains 22 tRNA genes, 13 protein-coding genes, 2 rRNA genes, and a non-coding control region with the total length of 16,497 bp. The gene arrangement and composition are similar to most of other fish. Most of the genes are encoded on heavy-strand, except for eight tRNA and ND6 genes. Just like most other vertebrates, the bias of G and C has been found in statistics results of different genes/regions. The complete mitochondrial genome sequence of Liobagrus marginatus would contribute to better understand population genetics, evolution of this lineage, and will help administrative departments to make rules and laws to protect it.
