Breadth-First Search using Dynamic Parallelism on the GPU

Breadth-First Search is an important basis for many different graph-based algorithms with applications ranging from peer-to-peer networking to garbage collection. However, the performance of different approaches depends strongly on the type of graph. In this paper, three algorithms of varying complexity are implemented using the CUDA Programming Model for the GPU and are compared to one another on a variety of different, sparse graphs. As part of this, we look into utilizing dynamic parallelism in order to both reduce overhead from latency between the CPU and GPU, as well as speed up the algorithm itself. Lastly, the same three algorithms are then integrated with the faimGraph framework for dynamic graphs and the relative performance to a Compressed-Sparse-Row data structure is examined. We show that our algorithm can be well adapted to the dynamic setting and outperforms another competing dynamic graph framework on our test set.
Development and subsequent refinement of the inflammatory bowel disease questionnaire: a quality-of-life instrument for adult patients with inflammatory bowel disease.

BACKGROUND Health-related quality of life (HRQOL) describes the physical, social, and emotional attitudes and behavior of people in relation to health status. By the 1980s, HRQOL was noted to be impaired in chronic diseases but inflammatory bowel disease, had not been extensively described. METHODS This review summarizes the results of several studies describing the development and application of a disease-specific HRQOL instrument, the Inflammatory Bowel Disease Questionnaire (IBDQ). RESULTS An initial study described how patients with inflammatory bowel disease identified 150 problems they had experienced in four domains: bowel, systemic, emotional, and social function. Almost half of patients underreported impairment until encouraged by a reminder list. Thirty-two questions were included in the final questionnaire and were scored on a 7-point scale from I (worst) to 7 (best) for a range of possible scores from 32 to 224. Physicians' and spouses' global assessments correlated poorly with patient-reported HRQOL. Subsequent validation of the IBDQ suggested a strong correlation with disease severity (r = -0.5; p < 0.001) and a test-retest reliability of 0.7. Mean score changes of 16 to 30 points have been linked to changes in therapy. Statistically significant differences also occur between active and inactive disease. Results of four clinical trials have included the IBDQ as a measure of outcome. A self-administered version and a shortened version of the IBDQ have also been validated. CONCLUSIONS The IBDQ is a valid, reliable, and sensitive measure that can be meaningfully applied in clinical trials. The short IBDQ may also be useful in clinical research and office practice.
SRF Controller in D-Statcom in Distribution Generation of PQ Improvement

This paper presents a modified instantaneous power control scheme of D-STATCOM for power factor and harmonic compensation. The proposed control strategy has been introduced in order to enhance some steady-state performances besides its functional elimination of power quality disturbances. Usage of SRF Controller to control the current . Power factor and harmonic current of a controlled feeder section are two vital roles in steady-state power distribution system operation. Utilizing an already installed D-STATCOM to achieve these additional control objectives can help system operators maximize overall system performances To verify its use, a 22-kV power distribution feeder with a three-phase rectifier load was tested.
Colistin-daptomycin, colistin-linezolid, colistin-vancomycin combination effects on colistin in multi-resistant acinetobacter baumannii strains

Objective : The most important problem in the treatment of nosocomial Acinetobacter baumannii (A. baumannii) infections which is increasingly seen in recent years is that almost all strains are resistant to many antibiotics, including carbapenems, and that the extinction of antibiotic options to be used in treatment. This leads the clinicians to new treatment options and suggests the use of combined antibiotics to achieve success in both the treatment of multi-drug-resistant A. baumannii (MDRAB) infections as well as to prevent resistance development. We investigated the in vitro activity of colistin in combination with vancomycin, linezolid or daptomycin against MDRAB to determine whether these combinations would be considered for clinical use. Methods: The fractional inhibitory concentration (FIC) index was used to determine the antibiotic combination effects and to evaluate the effect of antibiotic combinations on the bacteria. Results: MIC values of colistin/vancomycin, colistin/linezolid, and colistin/daptomycin in 10 strains (33.3%) gave similar results. Twenty strains gave different MIC results according to antibiotics. The colistin/daptomycin antagonistic ratio was high when the colistin/vancomycin synergy ratio was high compared to the others. Conclusion: Antibiotic combinations can be used as an alternative treatment approach in multi-drug resistant A. baumannii infections.
Multi-crop recognition using UAV-based high-resolution NDVI time-series

Multi-crop recognition is a highly nonlinear task in nature as it involves many dynamic factors to address. In this paper, a decision tree based approach is presented to classify and recognize 17 different crops. High spatial and temporal normalized difference vegetation index (NDVI) signatures were extracted from multispectral imagery using a multispectral sensor onboard the quadrotor. Detailed datasets were prepared through sampling based on normal distribution with different standard deviations. The impact of reduced dimensions was also tested using principal component analysis. A very high degree of accuracy was achieved for classification. The results also indicate that NDVIs pertaining to early-to-mid season have much more weight in the classification process for multiple crops.
Using Temporal Correlation to Optimize Stereo Matching in Video Sequences

SUMMARY The large computational complexity makes stereo matching a big challenge in real-time application scenario. The problem of stereo matching in a video sequence is slightly di ﬀ erent with that in a still image because there exists temporal correlation among video frames. However, no existing method considered temporal consistency of disparity for algo-rithm acceleration. In this work, we proposed a scheme called the dynamic disparity range (DDR) to optimize matching cost calculation and cost aggregation steps by narrowing disparity searching range, and a scheme called temporal cost aggregation path to optimize the cost aggregation step. Based on the schemes, we proposed the DDR-SGM and the DDR-MCCNN algorithms for the stereo matching in video sequences. Evaluation results showed that the proposed algorithms signiﬁcantly reduced the computational complexity with only very slight loss of accuracy. We proved that the proposed optimizations for the stereo matching are e ﬀ ective and the temporal consistency in stereo video is highly useful for either improving accuracy or reducing computational complexity.
An investigation into the degree of difference in image quality between images taken on varying speed film-screen systems

Abstract Purpose: Film-screen speed is one of the most critical factors affecting radiation dose to the patient, with faster speed systems requiring less radiation dose than slower speed systems for equivalent examinations. However, this is not without a cost, for accompanying this increase in speed, as well as a reduced patient dose, is a reduction in image quality. One must question whether this decrease in image quality is enough to be noticed by the human eye and, perhaps more importantly, whether it is enough to produce an image of undiagnostic quality. The aim of this research was to ascertain whether the increased radiation dose to the patient is really justified when using slower, more detailed intensifying screens, when perhaps the same diagnostic information could be achieved using faster film-screen systems with a decreased radiation dose. Methods: This investigation was mainly experimental in design and hence, the extraneous variables were carefully controlled. Identical density images of both a test tool and a hand phantom were evaluated subjectively under ideal viewing conditions by eight viewers, according to a specific set of criteria and a ranking scheme. Semi-quantitative evaluations of the test tool images were also carried out in order to facilitate the study. Results and Conclusions: Results from this research are tabulated and represented graphically. Friedman's two-way analysis of variance test and Wilcoxon's matched-pairs test are used to help analyse the data. The findings of this research would suggest that the same diagnostic information can often be produced with the faster speed systems as with the slower, more detailed intensifying screens. Therefore, opting for faster speed systems as a dose-reduction measure is certainly a feasible option. It was suggested that perhaps the best way of maximizing image quality and patient dose would be to choose film-screen speeds in accordance with pathologies under investigation. Despite the limitations of this research, which have been discussed in some depth, it has nevertheless highlighted the need for further study in this field. These findings would certainly support a large-scale study on this topic and it is hoped that this project would serve as a useful pilot to such an investigation.
On the end-of-life inventory problem

We consider the so-called End-of-Life inventory problem for a manufacturer of spare parts in the final phase of the service life cycle. The final phase starts when the part production is terminated and continues until the last service contract expires. One of the most popular tactics to cope with this problem is to place a sufficient volume of spare parts at the beginning of the final phase which is called the nal order quantity. Then the repair-replacement policy serves the costumers by repairing or replacing the defective items. On the other hand, nowadays, a considerable price erosion happens for the products while repair and service costs stay steady over time. If so, it is more cost effective to consider an alternative policy to meet the service demands after some time. This policy may offer the costumers a new product of similar type or a discount on a next generation product. In this setup, the purpose is to find an optimal pair of final order quantity and switching time to an alternative policy which minimizes the total expected discounted costs. We study this problem under the static and dynamic approaches which require different mathematical techniques.
Shallow Cnn with Lstm layer for tuberculosis detection in microscopic image

: Tuberculosis or TB, a disease mainly affecting lungs is infected by bacterium mycobacterium tuberculosis and diagnosed by careful examination of microscopic images taken from sputum specimen. Diagnosis of disease using microscopy and computer vision methods are applied for many previous practical problems. Recently, deep learning is playing major role in computer vision applications producing remarkable performance. But, computational complexity always remains as an obstacle in the application of deep learning in many aspects. So in this paper, a shallow CNN with LSTM layer is used for detecting the tubercle bacillus, mycobacterium tuberculosis, from the microscopic images of the specimen collected from the patients. The specified model is producing better performance than state of the art model and also have reduced number of learnable parameters, which requires comparatively less computation than the existing model.
Investigating the Performance of Turbo Code in WCDMA Downlink over Frequency Selective Rayleigh Fading Channel

In this research parallel concatenated convolutional coding with iterative decoding is examined for data transmission over the downlink of a WCDMA system employing BPSK modulation and coherent Rake receiver. Performance of parallel concatenated convolutional coding is studied in a frequency selective Rayleigh fading channel, new type of external interleaver which is called Dithered Golden Section Interleaver (DGSI) is used. The effect of correlated fading on the performance of the proposed system is investigated by considering external block interleaver delays of 10 ms at mobile speeds 5 km/h. Simulation results show that the employing of this type of interleaver is outperforming at high signal to noise ratios the classical random interleaver. خلا ـ صلا ـــــــ ة ًف اذه ثحبلا مت صحف زمرملا ا يزاوتمل صارتملا فتلملا مدختسملا لقنل تامولعملا ىلع طخلا ًلفسلا ةموظنمل WCDM نٌمضت ماظن مادختسا BPSK ا زمرملا ءادأ سرد دقف هكاشتملا لبقتسملا و يزاوتمل ةانق ةلاحل فتلملا صارتملا ًلٌار توفخ Rayleigh ددرتلا ةٌئاقتنا ، و تافحزم( ةٌجراخلا تافحزملا نم دٌدج عون مادختسا مت ةانقلا ةامسملاو ) ًبهذلا عطقملا تافحزمب . مدختسٌ يذلاو مدقملا ماظنلا عم هتنراقم تمتو هتسارد تمت حرتقملا ماظنلا ءادأ ىلع قباطتملا توفخلا رٌثأت نأ ًلاوح فٌحزت رٌثأتب ًمزحلأ فحزملا 10ms لومحم ةعرسب 5km/h . أ ناو ماظنلا نم لضفأ وه حرتقملا ماظنلا ءاد ًئاوشع رثعبم مدختسٌ يذلا يدٌلقت و دنع صاخ لكشب SNRs . ةٌلاعلا Asst.

PERCEPTIONS OF INSTRUCTORS AND STUDENTS IN TEAM TEACHING IN DUBAI PHARMACY COLLEGE

The aim of this primary study is to identify students' perspectives, analyze the issues involved with team teaching in interdisciplinary courses and to discuss the advantages and disadvantages of team teaching before implementation in Dubai Pharmacy College, UAE. Participants included 76 students, second year class, (female) and two full time faculty members act as course instructors, responsible for teaching physical pharmacy and Biopharmaceutics interdisciplinary courses. All respondents had no prior experiences with team taught classes. The main research method was a combination of quantitative and qualitative analysis. The research data included student scores, structured designed questionnaires, teachers’ self-reflection and students' perception. The research findings showed that the two teaching methods showed significant difference in respect of students’ perception. More than half of the experimental students preferred team teaching to traditional teaching. The reflection of team teachers’ expectations of team teaching and its implementation was evident. The differences in the teaching strategy also exposed team teachers to challenge and being compared with each other by students in class. In addition, the team teachers had been unprepared for this comparison, especially in regard to class management. The implementation of team teaching, however, was not approved by the college administration, due to time consuming in preparation of the session, which and caused students support regarding team teaching.
Towards a Prototype Platform for ROS Integrations on a Ground Robot

The intent of this work was to develop, evaluate, and demonstrate a prototype robot platform on which ROS integrations could be explored. With observations of features and requirements of existing industrial and service mobile ground robots, a platform was designed and outfitted with appropriate components to enable the most common operational-critical functionalities and account for unforeseen components and features. The resulting Arlo Demonstration Robot accommodates basic mapping, localization, and navigation in both two and three-dimensional space as well as additional safety and teleoperation features. The control system is centered around the Zybo Z7 FPGA SoC hosting a custom hardware design. The platform is validated through an analysis of feature requirements and limitations and additional evaluations of a series of real-world use cases demonstrating high-level behaviors. In order to promote further development, this work serves as detailed documentation of the selection, implementation, and testing of this platform and complements initial binary releases for the Zybo Z7 control system and accompanying source code for the functionalities implemented. This prototype robot stack can be further developed to enable additional capabilities and validate its performance in other real-world scenarios or used as a reference for porting to alternative robot platforms.

Methamphetamine: epidemiology, literature. Background: Despite initial reports of a decline in use in the early 2000s, methamphetamine remains a signiﬁcant public health concern with known neurotoxic and neurocognitive effects to the user. The goal of this review is to update the literature on methamphetamine use and addiction since its assent to peak popularity in 1990s. Methods: We ﬁrst review recent epidemiological reports with a focus on methamphetamine accessibil- ity, changes in use and disorder prevalence rates over time, and accurate estimates of the associated burden of care to the individual and society. Second, we review methamphetamine pharmacology lit- erature with emphasis on the structural and functional neurotoxic effects associated with repeated use of the drug. Third, we brieﬂy outline the ﬁndings on methamphetamine-related neurocognitive deﬁcits as assessed via behavioral and neuroimaging paradigms. Lastly, we review the clinical presentation of methamphetamine addiction and the evidence supporting the available psychosocial and pharmacolog- ical treatments within the context of an addiction biology framework. Conclusion: Taken together, this review provides a broad-based update of the available literature covering methamphetamine research over the past two decades and concludes with recommendations for future research.
An approach towards a harmonized framework for hydrographic features domain

We describe an ontology in the hydrographic domain, hydrOntology, which can be used to overcome the semantic heterogeneity of different databases and other information sources that deal with geographic information. We show that ontologies are richer than other means commonly used to represent geographic information, such as feature catalogues and thesauri, and how ontologies could be used to overcome some of the problems associated with them.
Community Detection in Social Networks: Literature Review

Due to easy and cost-effective ways, communication has amplified many folds among humans across the globe irrespective of time and geographic location. This has led to the construction of an enormous and a wide variety of social networks that is a network of social interactions or personal relations. Social network analysis (SNA) is the inspection of social networks in order to understand the participant’s arrangement and behaviour. Discovering communities from the social network has become one of the key research areas in SNA. Communities discovered from social networks facilitate its members so as to interact with relatable people who have similar or comparable interests. However, in present time, the enormous growth of social networks demands an intensive investigation of recent work carried out for identifying community division in social networks. This paper is an attempt to enlighten the ongoing developments in the domain of Community detection (CD) for SNA. Additionally, it sheds light on the algorithms which use meta-heuristic optimisation techniques to hit upon the community structure in social networks. Further, this paper gives a comparison of proposed methods in recent years and most frequently used optimisation approaches in the domain of CD. It also describes some application areas where CD methods have been used. This guides and encourages researchers to probe and take ahead the work in the area of detecting communities from social networks.
User failure to find known library items

Purpose – The purpose of this paper is to understand why users at the University of Nevada, Las Vegas (UNLV) are unable to locate locally held items from the university libraries' electronic and physical collections using the library web site and catalog.Design/methodology/approach – A combination of usability testing methods and quality control methods were used. Items for the study were selected from cancelled interlibrary loan requests. A cognitive walkthrough was performed for citations representative of the top categories of cancellation because the item is owned or available electronically. Quality control methods were used to determine likely user failure points to completing this path. Data from the cognitive walkthrough were compared with actual user behavior, as observed through usability testing.Findings – Participants in the study failed to locate known items for multiple reasons, but from the usability testing and analysis three major areas emerged: finding the correct starting‐point for the .
Severe acute‐hybrid rejection occurring nine months after kidney transplantation: a report of rescue by orchestration of antirejection therapies

Abstract: Although a majority of acute rejection (AR) in non‐sensitized recipients is T‐cell‐mediated by primed T cells, recent studies have shown that antibody‐mediated acute rejection occurs in 20–30% of AR, and that it is often refractory to conventional antirejection therapy; possibly leading to graft loss. We report a case of severe acute‐hybrid rejection consisting of both features in a non‐sensitized kidney recipient, which was rescued by the orchestration of antirejection therapies. A 33‐yr‐old Japanese male, with advanced‐stage chronic kidney disease with an unknown etiology, underwent a HLA 3/6 mismatch and ABO‐compatible living‐related kidney transplantation preemptively. He had an excellent clinical course, except for initial cytomegalovirus infection, with good graft function [serum creatinine (sCr) 1.1 mg/dL]. Nine months later, his creatinine abruptly increased to 2.1 mg/dL, when graft biopsy revealed acute T cell‐mediated rejection (ATMR) grade IA, and simultaneous acute antibody‐mediated rejection (AAMR) grade I. Antirejeciton therapy, comprising methyl‐prednisolone pulse and 15‐deoxyspergualin, and second line rituximab and plasmapheresis, was ineffective. Moreover, histologically and clinically, the rejection status deteriorated (ATMR grade III and AAMR grade III, max sCr 4.0 mg/dL). Next, we administered muromonab CD3 and basiliximab, which could eradicate the complicated severe AR without opportunistic infection, even under the strong immunosuppression. The present case implies that high‐grade combined rejection can respond to anti‐CD 20 and anti‐CD25 mAbs, without serious complication; however, post‐operative, thorough appropriate monitoring of immunosuppression is important because its effects are limited.
