A High Throughput Efficient Approach for Decoding LDPC Codes onto GPU Devices

Low density parity check (LDPC) decoding process is known as compute intensive. This kind of digital communication applications was recently implemented onto graphic processing unit (GPU) devices for LDPC code performance estimation and/or for real-time measurements. Overall previous studies about LDPC decoding on GPU were based on the implementation of the flooding-based decoding algorithm that provides massive computation parallelism. More efficient layered schedules were proposed in literature because decoder iteration can be split into sublayer iterations. These schedules seem to badly fit onto GPU devices due to restricted computation parallelism and complex memory access patterns. However, the layered schedules enable the decoding convergence to speed up by two. In this letter, we show that: 1) layered schedule can be efficiently implemented onto a GPU device; and 2) this approach-implemented onto a low-cost GPU device-provides higher throughputs with identical correction performances (BER) compared to previously published results.
The ALTRO chip: a 16-channel A/D converter and digital processor for gas detectors

The ALTRO (ALICE TPC Read Out) chip is a mixed-signal integrated circuit designed to be one of the building blocks of the readout electronics for gas detectors. Originally conceived and optimised for the Time Projection Chamber (TPC) of the ALICE experiment at the CERN LHC, its architecture and programmability makes it suitable for the readout of a wider class of gas detectors. In one single chip, the analogue signals from 16 channels are digitised, processed. compressed and stored in a multi-acquisition memory. The Analogue-to-Digital converters embedded in the chip have a 10-bit dynamic range and a maximum sampling rate in the range of 20 to 40 MHz. After digitisation, a pipelined hardwired processor is able to remove from the input signal a wide range of systematic and non- systematic perturbations, related to the non-ideal behaviour of lite detector, temperature variation of the electronics, environmental noise, etc. Moreover. the processor is able to suppress the signal tail within 1 /spl mu/s after the pulse peak with 0.1% accuracy thus narrowing the pulses to improve their identification. The signal is then compressed by removing all data below a programmable threshold, except for a specified number of pre- and post-samples around each peak. This produces non-zero data packets. Eventually, each data packet is marked with its time stamp and size - so that the original data can be reconstructed afterwards and stored in lite multi-acquisition memory that has a readout bandwidth of 300 Mbyte/sec. This paper addresses the algorithms of lite implemented digital functions and the performance of the ALTRO chip on measured data.
All stents are not alike or is the difference in the eye of the observer only?

recurrent transient ischaemia predicts a poor outcome in unstable angina patients who appear to be well treated with antiischaemic agents. Both sets of authors urge that intensive therapeutic approaches be considered in the more ischaemic patients. Specifically, Akkerhuis et al. suggest that continuous on-line ST segment monitoring can influence the triage and risk stratification of patients with unstable angina. Enhanced antithrombotic treatment and revascularization can then be used in those patients with persistent episodes of transient ischaemia who were initially thought to be at low risk for future cardiac events. Patel et al. also favour using revascularization procedures in their ‘refractory’ patients. The continuing instability of the vascular endothelium is a source of ongoing concern and probably warrants other approaches as well. I am thinking specifically of the decrease in transient ischaemia (and subsequent cardiac events) reported with statin therapy in patients with stable angina. This class of drugs makes the endothelium less vulnerable to the kinds of lesions associated with increased cardiovascular morbidity and mortality and may be especially valuable when a full regimen of ‘traditional’ antiischaemic agents (nitrates, betablockers, calcium blockers, antiplatelet drugs) are already being employed. There is preliminary data that ACE inhibitors may also be helpful. In the final analysis, however, it may be that coronary revascularization — and especially bypass surgery — offers the best prognosis for patients with ongoing ischaemia, whether stable or unstable, silent or symptomatic.

Bayesian Interactive Decision Support for Multi-Attribute Problems with Even Swaps

Even swaps is a method for solving deterministic multi-attribute decision problems where the decision maker iteratively simplifies the problem until the optimal alternative is revealed (Hammond et al. 1998, 1999). We present a new practical decision support system that takes a Bayesian approach to guiding the even swaps process, where the system makes queries based on its beliefs about the decision maker's preferences and updates them as the interactive process unfolds. Through experiments, we show that it is possible to learn enough about the decision maker's preferences to measurably reduce the cognitive burden, i.e. the number and complexity of queries posed by the system.
An Intervention Study Comparing Traditional and Ergonomic Microscopes

In recent years, manufacturers have produced new microscopes with claims of “ergonomic design” for reduced musculoskeletal stress among users. To test this claim, we measured posture of the neck, back, and upper extremities, and the prevalence of musculoskeletal and visual symptoms among cytotechnologists while using traditional microscopes (baseline) and again after the introduction of ergonomically designed microscopes. Participants were five full-time cytotechnologists, who used the microscope 6–8 hours per day and had reported discomfort while using traditional microscopes. Results showed the ergonomically designed microscopes were significantly more comfortable to use than the traditional microscopes for the neck and shoulders. Significant improvement in joint angles of the elbows (flexion) and shoulders (abduction) was noted with the ergonomically designed microscopes. These results suggest that ergonomically designed microscopes may reduce some of the risk factors for musculoskeletal disorders (MSDs) and benefit individuals who use microscopes for prolonged periods of time.
Statistics of dark matter haloes expected from weak lensing surveys

The distortion of the images of faint high-redshift galaxies can be used to probe the intervening mass distribution. This weak gravitational lensing effect has been used recently to study the (projected) mass distribution of several clusters at intermediate and high redshifts. In addition, the weak lensing effect can be employed to detect (dark) matter concentrations in the Universe, based on their mass properties alone. Thus it is feasible to obtain a mass-selected sample of `clusters', and thereby probe the full range of their mass-to-light ratios. We study the expected number density of such haloes that can be detected in ongoing and future deep wide-field imaging surveys, using the number density of haloes as predicted by the Press--Schechter theory, and modelling their mass profile by the `universal' density profile found by Navarro, Frenk & White. We find that in all cosmological models considered, the number density of haloes with a signal-to-noise ratio larger than 5 exceeds 10 per square degree. With the planned MEGACAM imaging survey of ∼ 25 deg2, it will be easily possible to distinguish between the most commonly discussed cosmological parameter sets.
Natural language processing in mental health applications using non-clinical texts†

Natural language processing (NLP) techniques can be used to make inferences about peoples' mental states from what they write on Facebook, Twitter and other social media. These inferences can then be used to create online pathways to direct people to health information and assistance and also to generate personalized interventions. Regrettably, the computational methods used to collect, process and utilize online writing data, as well as the evaluations of these techniques, are still dispersed in the literature. This paper provides a taxonomy of data sources and techniques that have been used for mental health support and intervention. Specifically, we review how social media and other data sources have been used to detect emotions and identify people who may be in need of psychological assistance; the computational techniques used in labeling and diagnosis; and finally, we discuss ways to generate and personalize mental health interventions. The overarching aim of this scoping review is to highlight areas of research where NLP has been applied in the mental health literature and to help develop a common language that draws together the fields of mental health, human-computer interaction and NLP.
A result of Gabber by

Our proof, which is different from Gabber’s proof, uses twisted sheaves. Indeed, a secondary goal of this paper is to show how using them some of the questions regarding the Brauer group are simplified. We do not claim any originality in defining α-twisted sheaves; these appear in work of Giraud, Caldararu, and Lieblich. Experts may skip Section 2 where we briefly explain what little we need about this notion.
Gain Control and Precision in Crayfish Visual Interneurons: Analysis and Simulation

A drill press and stand providing an improved apparatus for cutting holes in plate vitreous material. The drill press includes a drill motor, a drill tool attached to the drill motor for cutting through the work piece, and a motor support interconnecting to and supporting the drill motor on the stand. The stand includes a base which is attachable to the work surface by a large suction cup which is attached to the lower surface of the stand base. The stand also includes a collar integral to and generally perpendicular to the upper surface of the base into which a mating drill press standard, a part of the motor support may be inserted. The motor support also includes a positioning mechanism for longitudinally moving the drill motor along the standard and may include a biasing spring to counteract the weight of the motor, etc. The standard, along with the attached drill motor, may be pivoted about its longitudinal axis within the mating collar to allow drilling two holes at fixed distances apart through the work surface without repositioning the stand. The base includes a cutting coolant reservoir drill tool access hole which traps coolant inserted therein atop the work surface and around the hole cutting tool. A resilient coolant retaining ring fixed to the lower surface of the base just outside the perimeter of the tool access hole presses against the work surface as the stand is attached to the work surface, forming a liquid seal for the reservoir.
Hydrogel of Ketoconazole and PAMAM Dendrimers: Formulation and Antifungal Activity

Ketoconazole (KET), an imidazole derivative with well-known antifungal properties, is lipophilic and practically insoluble in water, therefore its clinical use has some practical disadvantages. The aim of the present study was to investigate the influence of PAMAM-NH2 and PAMAM-OH dendrimers generation 2 and generation 3 on the solubility and antifungal activity of KET and to design and evaluate KET hydrogel with PAMAM dendrimers. It was shown that the surface charge of PAMAM dendrimers strongly affects their influence on the improvement of solubility and antifungal activity of KET. The MIC and MFC values obtained by broth dilution method indicate that PAMAM-NH2 dendrimers significantly (up to 16-fold) increased the antifungal activity of KET against Candida strains (e.g., in culture Candida albicans 1103059/11 MIC value was 0.008 μg/mL and 0.064 μg/mL, and MFC was 2 μg/mL and 32 μg/mL for KET in 10 mg/mL solution of PAMAM-NH2 G2 and pure KET, respectively). Antifungal activity of designed KET hydrogel with PAMAM-NH2 dendrimers measured by the plate diffusion method was definitely higher than pure KET hydrogel and than commercial available product. It was shown that the improvement of solubility and in the consequence the higher KET release from hydrogels seems to be a very significant factor affecting antifungal activity of KET in hydrogels containing PAMAM dendrimers.
Induced Packet Loss Reduction by Max-Heap Overlay Construction Based on the Bandwidth-Latency Product Measures

Constructing max-heap-form overlay governed by node gain scores (NGSs), earned from requested bandwidth discrepancy ratio (BDR) with respect to available bandwidth, and latency discrepancy ratio (LDR) between the nodes and the source, reduces induced packet loss caused by schemes neglecting these parameters in constructing the tree. This proposal positions nodes using NGSfunction governed by available bandwidth, requested bandwidth, proposed latency to prospective parent, and best latency as advised by the source. BDR and LDR are set with a and (1,000-alpha) respective weights, and arbitrarily chosen a between 0 and 1,000. NGSs, used as nodelDs, maintain uniqueness and balance between the critical factors. Max-heap-form tree is constructed assuming that all the nodes possess NGS less than the source. For load balancing, parent-node can not accept another child until all its able siblings acquire same number. This scheme out-performs the others, like BASE, in packet delivery, link stress, and end-to-end delay.
The Role of the HIF-1α Transcription Factor in Increased Cell Division at Physiological Oxygen Tensions

HIF-1 is a transcription factor that mediates the cellular responses to low oxygen environments, mainly as a result of having an oxygen-labile subunit, HIF-1α. HIF-1α has been carefully studied in the context of severe hypoxic stresses (<1% O2), but it is also known to be present at oxygen tensions commonly found in normal tissues in vivo (∼1–13% O2), albeit at much lower levels. Its role under these physiological conditions is not fully understood. Here, we show that a transcriptionally active HIF-1α was up-regulated at 5% O2, both in normal and cancer cells, but only some of its target genes were elevated as a result. HIF-1α induction was in part dependent on the activation of the ERK1/2 MAPK signalling pathway, which we have previously shown is active at 5% O2. We also found that HIF-1α does not contribute to the protection against DNA damage that can be observed in low oxygen environments, and that there are certain DNA damaging agents, such as doxorubicin and actinomycin D, that prevent HIF-1α induction independently of p53. Moreover, absence of HIF-1α significantly reduced the growth advantage of cells cultured at 5% O2. In view of these data, we conclude that HIF-1α can be induced and activated at physiological oxygen tensions in a MAPK-dependent manner and that, although this does not lead to pro-survival responses to stress, it determines the increased cell proliferation rates that are common under these conditions.
A quantitative analysis of head movement behaviour during visual acuity assessment under prosthetic vision simulation

In most current vision prosthesis designs, head movement is the sole director of visual gaze and scanning due to the head-mounted nature of the camera. Study of this unnatural behaviour may provide insight into improved prosthesis designs and rehabilitation procedures. In this paper, we conducted a psychophysical study to investigate the characteristics of head movements of normally sighted subjects undergoing a visual acuity task in simulated prosthetic vision (SPV). In 12 naïve, untrained subjects, we recorded spontaneous changes in the amount of head movements during SPV sessions compared to control (normal vision) sessions. The observed behaviour continued to be refined until five or six sessions of practice. Increased head movement velocity was shown to be correlated to improved visual acuity performance, up to 0.3 logMAR, an equivalent of detecting details at half the physical size compared to complete deprivation of head movements. We postulate that visual scanning can as much as double the spatial frequency information in prosthetic vision. Increased head movement velocity observed when subjects were attempting smaller test items and for low-pass filtering schemes with higher cut-off frequencies may be further evidence that higher frequency content may be available through visual scanning, unconsciously driving subjects to increase head movement velocity.
The search for rebel interdependence

The existing conflict literature tends to treat interdependence between rebel groups as a binary category: either groups are allied or unallied, fragmented or unified, interdependent or independent. Yet much of our qualitative knowledge suggests that interdependence is better understood as a matter of degree where certain groups exert a disproportionate influence over their counterparts. The challenge is how to identify the degree of interdependence in practice. As a solution, I conceptualize interdependence as a property of a system of interactions between rebel groups and government forces within and across borders. My approach is to model the entire system of interactions in order to test hypotheses related to the directionality of influence and the potential for military coordination between groups. I demonstrate the utility of this approach by examining the relationship between Pakistan and the two major factions which make up the Taliban organization – the Afghan and Pakistani Taliban. I analyze the triangular system with a vector autoregressive model and monthly time series data on violent actions initiated by each group from January 2008 to February 2013. The substantive findings support much of the received wisdom concerning Pakistan’s disparate relationship to both groups, which is characterized by antagonism with the Pakistani Taliban and collusion with the Afghan Taliban. The results also suggest that the claims of interdependence between the two Taliban groups have been overstated.
Grounded Feature Selection for Biomedical Relation Extraction by the Combinative Approach

Relation extraction is an important task in biomedical areas such as protein-protein interaction, gene-disease interactions, and drug-disease interactions. In recent years, it has been widely researched to automatically extract biomedical relations in a vest amount of biomedical text data. In this paper, we propose a hybrid approach to extracting relations based on a rule-based approach feature set. We then use different classification algorithms such as SVM, Naïve Bayes, and Decision Tree classifiers for relation classification. The rationale for adopting shallow parsing and other NLP techniques to extract relations is two-folds: simplicity and robustness. We select seven features with the rule-based shallow parsing technique and evaluate the performance with four different PPI public corpora. Our experimental results show the stable performance in F-measure even with the relatively fewer features.
110-GHz static frequency divider in SiGe bipolar technology

We present a static frequency divider designed in a 225 GHz fT SiGe bipolar technology. The divider has a divide ratio of four and it is operational from 200 MHz up to 110 GHz (limited by the measurement equipment). At a -5.2 V power supply, the circuit, including the two dividers and the input and output stages, consumes less than 260 mA. Index Terms SiGe, Static Frequency Divider
Aerodynamics and Optimization of Airfoil Under Ground Effect

— The Prediction of aerodynamic characteristics and shape optimization of airfoil under the ground effect have been carried out by integration of computational fluid dynamics and the multi-objective Pareto-based genetic algorithm. The main flow characteristics around an airfoil of WIG craft are lift force, lift-to-drag ratio and static height stability ( H.S ). However, they show a strong trade-off phenomenon so that it is not easy to satisfy the design requirements simultaneously. This difficulty can be resolved by the optimal design. The above mentioned three characteristics are chosen as the objective functions and NACA0015 airfoil is considered as a baseline model in the present study. The profile of airfoil is constructed by Bezier curves with fourteen control points and these control points are adopted as the design variables. For multi-objective optimization problems, the optimal solutions are not unique but a set of non-dominated optima and they are called Pareto frontiers or Pareto sets. As the results of optimization, forty numbers of non- dominated Pareto optima can be obtained at thirty evolutions.
Freestyle race success in swimmers with intellectual disability

Athletes with intellectual disability (ID) competin g at international level show lower levels of explosive strength and cardiovascular fitness when compared to age matched trained persons. Behavioural characteristics such as motivation, and ability to deal with stress are more difficult to examine. In the 100-m freestyle race Paralympic competitors with loco-motor disability all use similar race speed and stroking strategies. But do trained and experienced swimmers with ID also generally adapt these patterns? Video race analysis data was collected on 81 elite male swimmers including ID athletes, loco-motor disabled, visually impaired as well as able bodied. In long course races there is a typical race patter n used by all swimmers with sufficient race experience regardless of absolute performance level . Individual race tactics do not generally determine the outcome.
Mental health issues and the Canadian criminal justice system**

Abstract The critics assert that a significant proportion of incarcerated individuals suffers from mental health issues, i.e. ‘the criminalization hypothesis. ’ The current paper reviews the scholarly literature to address five interrelated questions: (1) What are the risks of those classified as mentally ill for committing crimes and, in particular, violent crimes? (2) As the gatekeepers to the criminal justice system, what happens during ‘first encounters’ between the police with those who have mental illnesses? (3) What community-based services are available for effective diversions as an alternative to incarceration for those with mental illnesses? (4) What are the impacts of treatment options upon those experiencing mental illnesses while incarcerated, including the impact upon recidivism? (5) What types of pre-release planning and community responses have the most positive effects to help reduce recidivism and assist offenders in coping with mental health issues in the Canadian context? After summarizing key evidence pertaining to these questions, the paper presents case studies as exemplars of ‘best practices’ to illustrate promising directions conducive to integrated, holistic, and effective responses at the intersection of the criminal justice and mental health systems.
