Optimal Recharging With Practical Considerations in Wireless Rechargeable Sensor Network

Wireless energy transfer technologies have attracted increasing attention on empowering the wireless sensor nodes in recent years. In this paper, we consider a typical wireless rechargeable network, where a mobile charging vehicle is scheduled to charge a wireless sensor network with practical nodes’ deployment restrictions that may result in low charging efficiency for sensor nodes by charging vehicle. In our model, we take the effects of charging distance and angle on charging efficiency into consideration. Intuitively, there is an inevitable tradeoff between the charging distance and the angle. First of all, the scheduling traveling path of charging vehicle in previous studies has been proved to be NP-hard. Even worse, the nonlinear property between the charging distance and angle makes the problem even harder. For these concerns, we aim at minimizing the recharging cycle time, which contains the traveling time and recharging time. To this end, we prove that the charging vehicle would travel along the shortest Hamiltonian cycle. And we show the optimal charging location for each wireless charging incident. Experimental results demonstrate that our proposed solution could improve the charging efficiency around two times compared with the baseline scheme without optimization for angle and distance.
Smooth Tradeoffs between Insert and Query Complexity in Nearest Neighbor Search

Locality Sensitive Hashing (LSH) has emerged as the method of choice for high dimensional similarity search, a classical problem of interest in numerous applications. LSH-based solutions require that each data point be inserted into a number A of hash tables, after which a query can be answered by performing B lookups. The original LSH solution of [IM98] showed for the first time that both A and B can be made sublinear in the number of data points. Unfortunately, the classical LSH solution does not provide any tradeoff between insert and query complexity, whereas for data (respectively, query) intensive applications one would like to minimize insert time by choosing a smaller $A$ (respectively, minimize query time by choosing a smaller B). A partial remedy for this is provided by Entropy LSH [Pan06], which allows to make either inserts or queries essentially constant time at the expense of a loss in the other parameter, but no algorithm that achieves a smooth tradeoff is known. In this paper, we present an algorithm for performing similarity search under the Euclidean metric that resolves the problem above. Our solution is inspired by Entropy LSH, but uses a very different analysis to achieve a smooth tradeoff between insert and query complexity. Our results improve upon or match, up to lower order terms in the exponent, best known data-oblivious algorithms for the Euclidean metric.

What You Expect is NOT What You Get! Questioning Reconstruction/Classification Correlation of Stacked Convolutional Auto-Encoder Features

In this paper, we thoroughly investigate the quality of features produced by deep neural network architectures obtained by stacking and convolving Auto-Encoders. In particular, we are interested into the relation of their reconstruction score with their performance on document layout analysis. When using Auto-Encoders, intuitively one could assume that features which are good for reconstruction will also lead to high classification accuracies. However, we prove that this is not always the case. We examine the reconstruction score, training error and the results obtained if we were to use the same features for both input reconstruction and a classification task. We show that the reconstruction score is not a good metric because it is biased by the decoder quality. Furthermore, experimental results suggest that there is no correlation between the reconstruction score and the quality of features for a classification task and that given the network size and configuration it is not possible to make assumptions on its training error magnitude. Therefore we conclude that both, reconstruction score and training error should not be used jointly to evaluate the quality of the features produced by a Stacked Convolutional Auto-Encoders for a classification task. Consequently one should independently investigate the network classification abilities directly.
Towards wireless control for a permanent magnet synchronous motor

The problem of speed control of a permanent magnet synchronous motor is investigated in the presence of time delays due to wireless signal transmission among the controller, the sensors and the actuators. In the present paper, the decoupling controller approach proposed in [1] is extended to compensate the presence of the delays and to achieve satisfactory performance despite their presence. In particular, the research focuses mainly on the stability of the time delay closed loop system.
Glucose-6-phosphate Dehydrogenase Isoenzymes in Human Cell Cultures Determined by Sucrose-Agar Gel and Cellulose Acetate Zymograms∗

Summary Cell lines and strains were studied with respect to possession of G-6-PD isoenzymes, using cellulose acetate strips and sucrose-agar gel electrophoretic media. The latter provided higher resolution of A and B bands. The A and B types of G-6-PD were found to occur in human, diploid cultured cell populations in accordance with racial origin of the donor; while certain other heteroploid cell lines were found to possess A type G-6-PD irrespective of donor race.
Strategic Automation of Emotion Regulation Approaches to Emotion Regulation

As implementation intentions are a powerful self-regulation tool for thought and action (meta-analysis by P. M. Gollwitzer & P. Sheeran, 2006), the present studies were conducted to address their effectiveness in regulating emotional reactivity. Disgust-(Study 1) and fear-(Study 2) eliciting stimuli were viewed under 3 different self-regulation instructions: the goal intention to not get disgusted or frightened, respectively, this goal intention furnished with an implementation intention (i.e., an if-then plan), and a no-self-regulation control group. Only implementation-intention participants succeeded in reducing their disgust and fear reactions as compared to goal-intention and control participants. In Study 3, electro-cortical correlates (using dense-array electroencephalography) revealed differential early visual activity in response to spider slides in ignore implementation-intention participants, as reflected in a smaller PI. Theoretical and applied implications of the present findings for emotion regulation via implementation intentions are discussed. Many of life's daily problems are plagued by self-regulation failure. These self-regulatory difficulties have personal as well as We thank Alexander Jaudas for programming the studies, the members of the Social Psychology and Motivation lab and the Clinical Psychology and Neuropsychology lab at the University of Konstanz for helpful suggestions , as well as 11 burden our daily routines (e.g., eating). The self-regulation of emotions in particular bears upon how smoothly we interact with others in social relations and upon our productivity in work environments (Gross & Mufioz, 1995). Although the inability to self-regulate emotions may even evidence itself in major mental disorders , such as depression, not until recently has emotion regulation been an independent research topic on a theoretical and empirical level. In fact, the topic of emotion regulation was first studied within developmental psychology and afterwards adopted by adult literature, although a lack of integration of both developmental and adult emotion regulation still characterizes the field (Gross & Thompson, 2007). Two lines of theorizing can be distinguished: one based on general self-regulatory principles (e. and one focused directly on emotion regulation (e.g., Gross, 1998a, 1998b). In the present research, we suggest the possibility of emotion regulation through strategic automaticity created by implementation intentions (Gollwitzer, 1993, 1999). As research on implementation intentions focuses on the translation of goals into action (Gollwitzer & Sheeran, 2006), we attempt to bring insights of the self-regulation of goal implementation to bear on emotion regulation. We briefly review two central theories of emotion regulation. The first line of theorizing is based on general principles of psychological …
Improved walking ability and reduced therapeutic stress with an electromechanical gait device.

OBJECTIVE To evaluate the effectiveness of repetitive locomotor training using a newly developed electromechanical gait device compared with treadmill training/gait training with respect to patient's ambulatory motor outcome, necessary personnel resources, and discomfort experienced by therapists and patients. METHODS Randomized, controlled, cross-over trial. Sixteen non-ambulatory patients after stroke, severe brain or spinal cord injury sequentially received 2 kinds of gait training. Study intervention A: 20 treatments of locomotor training with an electromechanical gait device; control intervention B: 20 treatments of locomotor training with treadmill or task-oriented gait training. The primary variable was walking ability (Functional Ambulation Category). Secondary variables included gait velocity, Motricity-Index, Rivermead-Mobility-Index, number of therapists needed, and discomfort and effort of patients and therapists during training. RESULTS Gait ability and the other motor outcome related parameters improved for all patients, but without significant difference between intervention types. However, during intervention A, significantly fewer therapists were needed, and they reported less discomfort and a lower level of effort during training sessions. CONCLUSION Locomotor training with or without an electromechanical gait trainer leads to improved gait ability; however, using the electromechanical gait trainer requires less therapeutic assistance, and therapist discomfort is reduced.
An efficient and predictable implementation of asynchronous event handling in the RTSJ

Asynchronously happenings are crucial in real-time systems. Many real-time applications are designed with some periodic execution logics and a significant number of asynchronous events. Evidently it would not be a good performance choice if each event handler is constructed with its own thread of control. However it is generally unclear how to map threads to handlers effectively in the Real-Time Specification for Java (RTSJ). This paper, therefore, summarizes the Asynchronous Event Handler (AEH) techniques used in several popular RTSJ implementations and proposes two efficient and predictable implementations of AEH for the RTSJ. Currently the support for non-blocking handlers in the RTSJ is criticised as lacking in configurability [12] as the AEH of the RTSJ takes no advantage of non-blocking handlers. In the proposed models, non-blocking handlers are serviced by real-time threads that assume handlers may not block and blocking handlers are dealt by real-time threads that assume handlers may block. In this way it is possible to assign a thread to handlers at the right time in the right place while maintaining the least possible number of threads overall. We have implemented the proposed models on an existing RTSJ implementation, jRate. With the implementations of the models we ran a set of performance tests that measure their respective dispatch and multiple handlers completion latency. The results from the tests are promising and indicates that the proposed models have fewer threads on average with better performance than other approaches.
Morrison , Tom and Aickelin , Uwe ( 2002 ) ' An Artificial Immune System as a Recommender System for Web

Artificial Immune Systems have been used successfully to build recommender systems for film databases. In this research, an attempt is made to extend this idea to web site recommendation. A collection of more than 1000 individuals’ web profiles (alternatively called preferences / favourites / bookmarks file) will be used. URLs will be classified using the DMOZ (Directory Mozilla) database of the Open Directory Project as our ontology. This will then be used as the data for the Artificial Immune Systems rather than the actual addresses. The first attempt will involve using a simple classification code number coupled with the number of pages within that classification code. However, this implementation does not make use of the hierarchical tree-like structure of DMOZ. Consideration will then be given to the construction of a similarity measure for web profiles that makes use of this hierarchical information to build a better-informed Artificial Immune System.
Association Mapping for Epistasis and Environmental Interaction of Yield Traits in 323 Cotton Cultivars under 9 Different Environments

Improving yield is a major objective for cotton breeding schemes, and lint yield and its three component traits (boll number, boll weight and lint percentage) are complex traits controlled by multiple genes and various environments. Association mapping was performed to detect markers associated with these four traits using 651 simple sequence repeats (SSRs). A mixed linear model including epistasis and environmental interaction was used to screen the loci associated with these four yield traits by 323 accessions of Gossypium hirsutum L. evaluated in nine different environments. 251 significant loci were detected to be associated with lint yield and its three components, including 69 loci with individual effects and all involved in epistasis interactions. These significant loci explain ∼ 62.05% of the phenotypic variance (ranging from 49.06% ∼ 72.29% for these four traits). It was indicated by high contribution of environmental interaction to the phenotypic variance for lint yield and boll numbers, that genetic effects of SSR loci were susceptible to environment factors. Shared loci were also observed among these four traits, which may be used for simultaneous improvement in cotton breeding for yield traits. Furthermore, consistent and elite loci were screened with −Log10 (P-value) >8.0 based on predicted effects of loci detected in different environments. There was one locus and 6 pairs of epistasis for lint yield, 4 loci and 10 epistasis for boll number, 15 loci and 2 epistasis for boll weight, and 2 loci and 5 epistasis for lint percentage, respectively. These results provided insights into the genetic basis of lint yield and its components and may be useful for marker-assisted breeding to improve cotton production.
Genome-wide alteration in DNA hydroxymethylation in the sperm from bisphenol A-exposed men

Environmental BPA exposure has been shown to impact human sperm concentration and motility, as well as rodent spermatogenesis. However, it is unclear whether BPA exposure is associated with alteration in DNA hydroxymethylation, a marker for epigenetic modification, in human sperm. A genome-wide DNA hydroxymethylation study was performed using sperm samples of men who were occupationally exposed to BPA. Compared with controls who had no occupational BPA exposure, the total levels of 5-hydroxymethylcytosine (5hmc) increased significantly (19.37% increase) in BPA-exposed men, with 72.69% of genome regions harboring 5hmc. A total of 9,610 differential 5hmc regions (DhMRs) were revealed in BPA-exposed men relative to controls, which were mainly located in intergenic and intron regions. These DhMRs were composed of 8,670 hyper-hMRs and 940 hypo-hMRs, affecting 2,008 genes and the repetitive elements. The hyper-hMRs affected genes were enriched in pathways associated with nervous system, development, cardiovascular diseases and signal transduction. Additionally, enrichment of 5hmc was observed in the promoters of eight maternally expressed imprinted genes in BPA-exposed sperm. Some of the BPA-affected genes, for example, MLH1, CHD2, SPATA12 and SPATA20 might participate in the response to DNA damage in germ cells caused by BPA. Our analysis showed that enrichment of 5hmc both in promoters and gene bodies is higher in the genes whose expression has been detected in human sperm than those whose expression is absent. Importantly, we observed that BPA exposure affected the 5hmc level in 11.4% of these genes expressed in sperm, and in 6.85% of the sperm genome. Finally, we also observed that BPA exposure tends to change the 5hmc enrichment in the genes which was previously reported to be distributed with the trimethylated Histone 3 (H3K27me3, H3K4me2 or H3K4me3) in sperm. Thus, these results suggest that BPA exposure likely interferes with gene expression via affecting DNA hydroxymethylation in a way partially dependent on trimethylation of H3 in human spermatogenesis. Our current study reveals a new mechanism by which BPA exposure reduces human sperm quality.
Association of poor subjective sleep quality with risk for death by suicide during a 10-year period: a longitudinal, population-based study of late life.

IMPORTANCE Older adults have high rates of sleep disturbance, die by suicide at disproportionately higher rates compared with other age groups, and tend to visit their physician in the weeks preceding suicide death. To our knowledge, to date, no study has examined disturbed sleep as an independent risk factor for late-life suicide. OBJECTIVE To examine the relative independent risk for suicide associated with poor subjective sleep quality in a population-based study of older adults during a 10-year observation period. DESIGN, SETTING, AND PARTICIPANTS A longitudinal case-control cohort study of late-life suicide among a multisite, population-based community sample of older adults participating in the Established Populations for Epidemiologic Studies of the Elderly. Of 14 456 community older adults sampled, 400 control subjects were matched (on age, sex, and study site) to 20 suicide decedents. MAIN OUTCOMES AND MEASURES Primary measures included the Sleep Quality Index, the Center for Epidemiologic Studies-Depression Scale, and vital statistics. RESULTS Hierarchical logistic regressions revealed that poor sleep quality at baseline was significantly associated with increased risk for suicide (odds ratio [OR], 1.39; 95% CI, 1.14-1.69; P < .001) by 10 follow-up years. In addition, 2 sleep items were individually associated with elevated risk for suicide at 10-year follow-up: difficulty falling asleep (OR, 2.24; 95% CI, 1.27-3.93; P < .01) and nonrestorative sleep (OR, 2.17; 95% CI, 1.28-3.67; P < .01). Controlling for depressive symptoms, baseline self-reported sleep quality was associated with increased risk for death by suicide (OR, 1.30; 95% CI, 1.04-1.63; P < .05). CONCLUSIONS AND RELEVANCE Our results indicate that poor subjective sleep quality is associated with increased risk for death by suicide 10 years later, even after adjustment for depressive symptoms. Disturbed sleep appears to confer considerable risk, independent of depressed mood, for the most severe suicidal behaviors and may warrant inclusion in suicide risk assessment frameworks to enhance detection of risk and intervention opportunity in late life.
Molecular Aspects of Antitumor Effects of a New Platinum(IV) Drug

The new platinum(IV) complex cis,trans,cis-[PtCl2(CH3COO)2-(NH3)(1-adamantylamine)] [adamplatin(IV)] seems promising for the perspective application in therapy of corresponding tumors. It is therefore of great interest to understand details of mechanisms underlying its biological efficacy. Cellular uptake of the drug, alterations in the target DNA induced by platinum drugs along with processing of platinum-induced damage to DNA and drug inactivation by sulfur-containing compounds belong to major pharmacological factors affecting antitumor effects of platinum compounds. We examined in the present work the significance of these factors in the mechanism of antitumor effects of adamplatin(IV) and compared the results with those of the parallel studies performed with “conventional” cisplatin. The results show that deactivation of adamplatin(IV) by sulfur-containing compounds (such as glutathione or metallothioneins) is likely to play a less significant role in the mechanism of resistance of tumor cells to adamplatin(IV) in contrast to the role of these reactions in the effects of cisplatin. Moreover, the treatment of tumor cells with adamplatin(IV) does not result in DNA modifications that would be markedly different from those produced by cisplatin. In contrast, the effects of other factors, such as enhanced accumulation of the drug in cells, strong inhibition of DNA polymerization by these adducts, lowered DNA repair, and DNA-protein cross-linking are different from the effects of these factors in the mechanism underlying activity of cisplatin. Hence, the differences between effects of adamplatin(IV) and cisplatin observed in the present work on molecular level may help understand the unique activity of adamplatin(IV).
Presence of JP2 and Non-JP2 Genotypes of Aggregatibacter actinomycetemcomitans and attachment loss in adolescents in Ghana.

BACKGROUND Limited data are reported concerning the presence of A. actinomycetemcomitans and attachment loss (AL) in sub-Saharan countries. The authors investigate the carrier frequency of JP2 and non-JP2 genotypes of A. actinomycetemcomitans and the presence of AL in Ghanaian adolescents and evaluate socioeconomic conditions and oral hygiene practices. METHODS Five hundred individuals (mean ± SD age: 13.2 ± 1.5 years) in public and private schools were interviewed about demographic characteristics and oral hygiene practices and were given a full-mouth periodontal examination. Subgingival plaque samples were obtained from periodontal sites around permanent first molars and incisors. The carrier status of A. actinomycetemcomitans at the individual level was determined based on results obtained by cultivation and polymerase chain reaction. RESULTS The findings of this study show a relatively high carrier rate of JP2 and non-JP2 genotypes of Aggregatibacter actinomycetemcomitans in the Ghanaian adolescent population and the presence of this bacterium is associated with the occurrence of AL. The overall carrier rate of A. actinomycetemcomitans was 54.4%, and the highly leukotoxic JP2 genotype was detected in 8.8% of the study population. A total of 107 (21.4%) individuals had ≥ 1 tooth with AL ≥ 3 mm. The majority of the individuals carrying A. actinomycetemcomitans (80.1%) (P <0.001) and of the periodontally diseased individuals (91.6%) (P <0.001) were found in public schools. CONCLUSIONS A. actinomycetemcomitans and AL were frequently found in Ghanaian adolescents. The school type was the strongest predictor of both presence of A. actinomycetemcomitans and AL.
