Energy-Efficient Distributed Compressed Sensing Data Aggregation for Cluster-Based Underwater Acoustic Sensor Networks

Energy-efficient data aggregation is important for underwater acoustic sensor networks due to its energy constrained character. In this paper, we propose a kind of energy-efficient data aggregation scheme to reduce communication cost and to prolong network lifetime based on distributed compressed sensing theory. First, we introduce a distributed compressed sensing model for a cluster-based underwater acoustic sensor network in which spatial and temporal correlations are both considered. Second, two schemes, namely, BUTM-DCS (block upper triangular matrix DCS) and BDM-DCS (block diagonal matrix DCS), are proposed based on the design of observation matrix with strictly restricted isometric property. Both schemes take multihop underwater acoustic communication cost into account. Finally, a distributed compressed sensing reconstruction algorithm, DCS-SOMP (Simultaneous Orthogonal Matching Pursuit for DCS), is adopted to recover raw sensor readings at the fusion center. We performed simulation experiments on both the synthesized and real sensor readings. The results demonstrate that the new data aggregation schemes can reduce energy cost by more than 95 percent compared with conventional data aggregation schemes when the cluster number is 20.
TREC-5 Experiments at Dublin City University: Query Space Reduction, Spanish & Character Shape Encoding

In this paper we describe work done as part of the TREC-5 benchmarking exercise by a team from Dublin City University. In TREC-5 we had three activities as follows: 1) Our ad hoc submissions employ Query Space Reduction techniques which attempt to minimise the amount of data processed by an IR search engine during the retrieval process. We submitted four runs for evaluation, two automatic and two manual with one automatic run and one manual run employing our Query Space Reduction techniques. The paper reports our findings in terms of retrieval effectiveness and also in terms of the savings we make in execution time. 2) Our submission to the multi-lingual track (Spanish) in TREC-5 involves evaluating the performance of a new stemming algorithm for Spanish developed by Martin Porter. We submitted threee runs for evaluation, two automatic, and one manual, involving a manual expansion from retrieved documents. 3) Character shape coding (CSC) is a technique for representing scanned text using a much reduced alphabet. It has been developed by Larry Spitz of Daimler Benz as an alternative to full-scale OCR for paper documents. Some of our TREC-5 experiments have started evaluating the performance of a CSC representation of scanned documents for information retrieval and this paper outlines our future work in this area
A Boost-Inverter-Based Bipolar High-Voltage Pulse Generator

Bipolar repetitive high-voltage pulse generators are commonly used in modern pulsed power applications. Conventionally, bipolar high-voltage pulses can be generated by adding a high-voltage H-bridge at the output stage of a unipolar high-voltage pulse generator which increases complexity and cost of the bipolar high-voltage pulse generator. In this paper, a boost-inverter-based bipolar high-voltage pulse generator with high-voltage gain is proposed. The proposed generator can provide high-voltage bipolar output pulses with the desired specifications from a low input dc voltage. The proposed generator is based on employing two bidirectional boost dc–dc converters, where the load is connected differentially between the boost converters’ output terminals. In the proposed approach, four controlled switches are required. Only two out of these four switches are rated at the high-voltage output level which affects positively the system cost. A detailed illustration of the proposed approach along with the design of its passive components is presented in this study. Simulation and experimental results are used to validate the proposed approach.
Locomotion of a legged capsule in the gastrointestinal tract: theoretical study and preliminary technological results

This work illustrates the analysis of locomotion in the gastrointestinal tract obtainable by a legged capsule for diagnostic and therapeutic purposes. A preliminary simulation of the legged locomotion onto slippery and deformable substrates has been performed and -simultaneously- mechanisms for on board actuation of the legs have been developed and tested. Moreover, an engineering translation of medical needs in endoscopy is presented, with some ad hoc solutions for improving diagnostic capabilities.
Adhesion-adaptive control of a novel bridge-climbing robot

In view of the present situation of bridge inspection equipment, a novel bridge inspection method is proposed and a wall-climbing robot based on negative pressure adhesion mechanism with adaptive control is developed. To meet the bridge inspection requirements, the developed robot consists of adhesion module, movement module, control module and crack detect module. The rough bridge wall environment is a challenging problem for adhesion. To address the problem, an adhesion adaptive control method based on pressure closed-up control is proposed. The method is described in detail and the overall system model is analyzed, including gap interference model. The PID parameters are well tuned to make a better system performance. The simulations with different gap interference are done and results are discussed respectively. The feasibility of robot which adopts adhesion adaptive control method is demonstrated by the simulation results. Finally, the effectiveness of the system is verified by the experiments conducted on various roughness walls.
Spatial and Temporal Association of Outbreaks of H 5 N 1 Influenza Virus Infection in Wild Birds with the 0 u C Isotherm

Wild bird movements and aggregations following spells of cold weather may have resulted in the spread of highly pathogenic avian influenza virus (HPAIV) H5N1 in Europe during the winter of 2005–2006. Waterbirds are constrained in winter to areas where bodies of water remain unfrozen in order to feed. On the one hand, waterbirds may choose to winter as close as possible to their breeding grounds in order to conserve energy for subsequent reproduction, and may be displaced by cold fronts. On the other hand, waterbirds may choose to winter in regions where adverse weather conditions are rare, and may be slowed by cold fronts upon their journey back to the breeding grounds, which typically starts before the end of winter. Waterbirds will thus tend to aggregate along cold fronts close to the 0uC isotherm during winter, creating conditions that favour HPAIV H5N1 transmission and spread. We determined that the occurrence of outbreaks of HPAIV H5N1 infection in waterbirds in Europe during the winter of 2005–2006 was associated with temperatures close to 0uC. The analysis suggests a significant spatial and temporal association of outbreaks caused by HPAIV H5N1 in wild birds with maximum surface air temperatures of 0uC–2uC on the day of the outbreaks and the two preceding days. At locations where waterbird census data have been collected since 1990, maximum mallard counts occurred when average and maximum surface air temperatures were 0uC and 3uC, respectively. Overall, the abundance of mallards (Anas platyrhynchos) and common pochards (Aythya ferina) was highest when surface air temperatures were lower than the mean temperatures of the region investigated. The analysis implies that waterbird movements associated with cold weather, and congregation of waterbirds along the 0uC isotherm likely contributed to the spread and geographical distribution of outbreaks of HPAIV H5N1 infection in wild birds in Europe during the winter of 2005–2006.

Radio Continuum Emission in Polar Ring Galaxies

We have used the Very Large Array aperture synthesis telescope to conduct a radio continuum survey of polar ring galaxies, at 20 cm and 6 cm. Forty objects were observed at 20 cm with ≃5″ resolution. Twenty (50%) of the program sources were detected at 20 cm, down to our 5 σ limit of 0.5 mJy beam-1. This detection rate is similar to those in surveys with comparable sensitivity for early-type galaxies without polar rings. Sixteen of the objects we detected at 20 cm were also observed at 6 cm. We show radio continuum maps for the five objects in our sample that have noticeably extended emission. Our spatial resolution was sufficient to distinguish emission originating in the host galaxy from that in the polar ring. The radio morphology of the extended sources, as well as the ratio of radio to far-infrared flux and the radio spectral indices of our detected sources, indicate that star formation, not nuclear activity, is the dominant source of the radio continuum emission in polar ring galaxies. However, the implied star formation rates are modest, and only one of our sample galaxies will consume its supply of cool gas within 500 Myr.
A temporal difference account of avoidance learning

Aversive processing plays a central role in human phobic fears and may also be important in some symptoms of psychosis. We developed a temporal-difference model of the conditioned avoidance response, an important experimental model for aversive learning which is also a central pharmacological model of psychosis. In the model, dopamine neurons reported outcomes that were better than the learner expected, typically coming from reaching safety states, and thus controlled the acquisition of a suitable policy. The model accounts for normal conditioned avoidance learning, the persistence of responding in extinction, and critical effects of dopamine blockade, notably that subjects experiencing shocks under dopamine blockade, and hence failing to avoid them, nevertheless develop avoidance responses when both shocks and dopamine blockade are subsequently removed. These postulated roles of dopamine in aversive learning can thus account for many of the effects of dopaminergic modulation seen in laboratory models of psychopathological processes.
John Allen Hendricks (ed.), The Twenty-first-century Media Industry: Economic and Managerial Implications in the Age of New Media

Transmedia Television falls squarely within the larger domain of media convergence studies. Of course, media convergence has broader significance than transmediality and encompasses merging of technologies, content, regulations, and economics. The author makes a worthwhile contribution to this body of research by comparing the narrative aspects of mainstream and new television platforms and evaluating qualitatively the audience’s level of engagement with online and mobile phone content.
BİREYLERİN MUTLULUK DÜZEYLERİNİN ORDİNAL LOJİSTİK REGRESYON ANALİZİ İLE İNCELENMESİ-ANALYSING LEVELS OF HAPPINESS OF INDIVIDUALS WITH ORDINAL LOGISTIC ANALYSIS

Mutluluk kavrami son yillarda onemi gittikce artan bir konudur. Mutluluk kavraminin guncel ve gelisime acik bir konu olmasi sebebiyle tercih edildigi bu calismada, 2007 yili Avrupa Yasam Kalitesi Anketi araciligiyla elde edilen ikincil veri kullanilmistir. Mutluluk degiskeni bagimli degisken olarak secilmis ve ilgili paket program araciligiyla analiz icin uygun sekle donusturulerek kullanilmistir. Ordinal Lojistik Regresyon Analizi araciligiyla sosyo-demografik ozelliklere gore mutluluk duzeyleri incelenmis ve elde edilen sonuclarla bu konuya dair yapilmis diger calismalarin sonuclari karsilastirilmistir. Dolayisiyla calismanin esas amaci mutluluk duzeyinin yillar itibariyle degisiminin farkli calismalarla ortaya konulmasidir. Elde edilen analiz sonuclari ile mevcut calismalarin sonuclari incelendiginde mutluluk duzeylerinin yillara gore sosyo-demografik ozellikler acisindan farklilasabildigi, ancak yine de temelde benzer sonuclar verdigi gorulmustur. - The happiness started gaining more importance during the recent years. The happiness conceptual was preferred in this study due to the fact that it is always a current and open to development subject, the secondary data obtained in 2007 through the European Quality of Life Survey were used. The variable, “happiness” was selected as a dependant variable and it was used after being converted into the form apt for analysis through the use of the relevant packaged software. Through the use of the Ordinal Logistics Regression Analysis, the levels of happiness were studied based on the socio-demographic properties and the results obtained were compared with the results of the studies performed on this subject. The main objective of this study is to submit the changes of levels of happiness in years through miscellaneous studies. As the results of the analysis obtained and the current studies are studied, it was seen that the levels of happiness may vary in terms of socio-demographical properties based on the years; however it basically gives the same results.
A Service-Oriented Approach to Crowdsensing for Accessible Smart Mobility Scenarios

This work presents an architecture to help designing and deploying smart mobility applications. The proposed solution builds on the experience already matured by the authors in different fields: crowdsourcing and sensing done by users to gather data related to urban barriers and facilities, computation of personalized paths for users with special needs, and integration of open data provided by bus companies to identify the actual accessibility features and estimate the real arrival time of vehicles at stops. In terms of functionality, the first “monolithic” prototype fulfilled the goal of composing the aforementioned pieces of information to support citizens with reduced mobility (users with disabilities and/or elderly people) in their urban movements. In this paper, we describe a service-oriented architecture that exploits the microservices orchestration paradigm to enable the creation of new services and to make the management of the various data sources easier and more effective. The proposed platform exposes standardized interfaces to access data, implements common services to manage metadata associated with them, such as trustworthiness and provenance, and provides an orchestration language to create complex services, naturally mapping their internal workflow to code. The manuscript demonstrates the effectiveness of the approach by means of some case studies.
Glycogen Synthase Kinase-3 (cid:1) Mediates Endoplasmic Reticulum Stress-Induced Lysosomal Apoptosis in Leukemia □

Glycogen synthase kinase (GSK)-3 (cid:1) may modulate endoplasmic reticulum (ER) stress-induced apoptosis; however, the mecha- nism remains unclear. Our data showed that human monocytic leukemia/lymphoma U937 and acute myeloid leukemia HL-60, but not chronic myeloid leukemia K562, cells were susceptible to apoptosis induced by ER stressor tunicamycin, a protein glyco- sylation inhibitor. Tunicamycin caused early activation of caspase-2, -3, -4, and -8, followed by apoptosis, whereas caspase-9 was slowly activated. Inhibiting caspase-2 reduced activation of caspase-8 and -3 but had no effect on caspase-4. Tunicamycin induced apoptosis independently of the mitochondrial pathway but caused lysosomal destabilization followed by lysosomal membrane permeabilization (LMP), cathepsin B reloca- tion from lysosomes to the cytosol, and caspase-8 and -3 activation. It is notable that caspase-2 mediated lysosomal destabiliza- tion. Inhibiting GSK-3 (cid:1) comprehensively reduced lysosomal apoptosis after caspase-2 inhibition. Unlike U937 and HL-60 cells, K562 cells showed nonresponsive ER stress and failure of activation of GSK-3 (cid:1) and caspase-2 in response to tunicamycin. Activating GSK-3 (cid:1) caused K562 cells to be susceptible to tunicamy-cin-induced apoptosis. Taken together, we show that GSK-3 (cid:1) exhibits a mechanism of ER stress-induced lysosomal apoptosis in leukemia involving caspase-2-induced LMP and cathepsin B relocation, which result in caspase-8 and -3 activation. combination with the increased diffuse (cytosolic and nuclei) green fluorescence (monomer form) may imply the deterioration of lysosomal membrane stability with a decreased proton gradient, which permits the leakage of the lysosomal contents cytosol. levels of LMP with In simultaneously examined fluores- (BX51).
Platelet-derived growth factor receptor inhibitor imatinib mesylate and docetaxel: a modular phase I trial in androgen-independent prostate cancer.

PURPOSE To study the platelet-derived growth factor receptor (PDGFR) inhibitor imatinib mesylate in androgen-independent prostate cancer (AIPC), alone and in combination with docetaxel, we designed a modular phase I trial. Our goals were to (1) evaluate the toxicity and maximum-tolerated dose of docetaxel with imatinib, and (2) evaluate the decline of prostate-specific antigen (PSA) induced by imatinib alone, and imatinib and docetaxel. PATIENTS AND METHODS Twenty-eight men with AIPC and bone metastases were enrolled to receive imatinib 600 mg daily lead-in for 30 days, then imatinib 600 mg daily and one of six possible doses of docetaxel weekly for 4 weeks every 6 weeks. RESULTS During the imatinib lead-in module, one dose-limiting toxicity (DLT) event was observed, while two (7%) of 28 had PSA decline (both < 50%). With imatinib and docetaxel, cycle 1 DLT was found in three of 12 patients at docetaxel 30 mg/m(2), in three of four patients at docetaxel 45 mg/m(2), and in five of six patients at docetaxel 35 mg/m(2). DLTs (n = 40 total events) were principally fatigue (35%) and nausea (20%). Eight (38%) of 21 had PSA decline greater than 50%, and six (29%) of 21 had PSA decline less than 50%. Serial PSA declines beyond 18 months were observed. PDGFR-expressing tumor declined on serial bone marrow biopsies with combination therapy alone. CONCLUSION With imatinib 600 mg daily, the maximum-tolerated dose of docetaxel was determined to be 30 mg/m(2) weekly for 4 weeks every 6 weeks. Long-term responses were observed. The role of imatinib in modulating outcomes to docetaxel in AIPC is being tested in a randomized phase II trial.
ENHANCING THE PERFORMANCE OF SVM CLASSIFICATION BASED ON FISHER LINEAR DISCRIMINANT

Support Vector Machine (SVM) is one of the important classification method used in many areas. Normal support vector machine is not suitable for classification of large data sets due to its high training complexity. Training of SVM with data number n has time complexity between O(n 2 ) and O(n 3 ). This paper introduces a novel data reduction method Fisher’s decision tree for SVM classification. It is a classifier uses the dimensionality reduction of Fisher Linear Discriminant and decomposition strategy of decision trees. The proposed classifier has distinctive advantages on dealing with large data sets.
Prior mating success can affect allocation towards future sexual signaling in crickets

Fitness is often correlated with the expression level of a sexually selected trait. However, sexually selected traits are costly to express such that investment in their expression should be optimised to maximize their overall fitness gains. Social interactions, in the form of successful and unsuccessful matings, may offer males one type of feedback allowing them to gauge how to allocate their resources towards sexual signaling. Here we tested whether adult male black field crickets (Teleogryllus commodus) modify the extent of their calling effort (the sexually selected trait) in response to successful and unsuccessful matings with females. To examine the effect that mating interactions with females have on investment into sexual signaling, we monitored male calling effort after maturation and then provided males with a female at two points within their life, manipulating whether or not males were able to successfully mate each time. Our results demonstrate that males alter their investment towards sexual signaling in response to successful matings, but only if the experience occurs early in their life. Males that mated early decreased their calling effort sooner than males that were denied a mating. Our results demonstrate that social feedback in the form of successful and unsuccessful matings has the potential to alter the effort a male places towards sexual signaling.
Lightly Supervised Quality Estimation

Evaluating the quality of output from language processing systems such as machine translation or speech recognition is an essential step in ensuring that they are sufficient for practical use. However, depending on the practical requirements, evaluation approaches can differ strongly. Often, reference-based evaluation measures (such as BLEU or WER) are appealing because they are cheap and allow rapid quantitative comparison. On the other hand, practitioners often focus on manual evaluation because they must deal with frequently changing domains and quality standards requested by customers, for which reference-based evaluation is insufficient or not possible due to missing in-domain reference data (Harris et al., 2016). In this paper, we attempt to bridge this gap by proposing a framework for lightly supervised quality estimation. We collect manually annotated scores for a small number of segments in a test corpus or document, and combine them with automatically predicted quality scores for the remaining segments to predict an overall quality estimate. An evaluation shows that our framework estimates quality more reliably than using fully automatic quality estimation approaches, while keeping annotation effort low by not requiring full references to be available for the particular domain.
Optimal Selection of Imperfect Tests for Fault Detection and Isolation

In this paper, we propose new formulations for the problem of test selection in the presence of imperfect tests in order to minimize the total costs of tests subject to lower bound constraints on fault detection and fault isolation. Our formulation allows tests to have multiple outcomes and delays caused by fault propagation, reporting, and transmission. Since the test selection problem is NP-hard even in the presence of perfect binary tests with no delays, we propose genetic algorithm (GA) and Lagrangian relaxation algorithm (LRA) to solve this problem. GA is a general approach for solving the problem with imperfect tests, including the scenarios with delayed and multiple test outcomes. The LRA is suitable for problems with perfect tests, including multiple outcomes. A key advantage of the LRA approach is that it provides an approximate duality gap, which is an upper bound measure of suboptimality of the solution. Our formulations and algorithms are tested on various real-world and simulated systems, and comparisons are made with previous test selection methods developed for perfect tests with no delays. The results show that our methods can efficiently solve the imperfect test selection problem. In addition, they have better performance (measured in terms of the number of tests used) than the methods in the literature for the perfect test selection cases. Finally, the GA has better computational efficiency than the LRA for all of the scenarios with perfect tests.
