An appraisal to optimize SQL queries

Performance engineering is a vital aspect in the SQL statement crafting. SQL is a non-procedural language and gives the wrong impression that the form of the SQL statement does not matter provided it produces the accurate result set. Statements which are not cautiously designed can instigate massive performance issues. There subsists many ways of writing SQL statement to retrieve same result set, but the one which imposes minimum impact on DBMS engine is always esteemed. The proposed model is intended to serve as benchmark for the tuning SQL queries and thus improving Query performance. This paper enunciates sundry techniques that can serve as an SQL Tuning tool for programmers. Our analysis ensured reduction in time and space complexity.
Model-based Recovery Connectors for Self-adaptation and Self-healing

Self-healing and self-configuration are highly desirable properties in software systems so that components can dynamically adapt to changing environments and recover from failure with minimal human intervention. This paper discusses a model-based approach for self-healing and self-configuration using recovery connectors. A recovery connector extends connectors in component-based software architectures and serviceoriented architectures with self-healing and self-configuration capabilities so that a component or service can be dynamically adapted and recovered from failures. The design of the recovery connector is based on the MAPE-K loop model and can handle both recovery and adaptation.
Accuracy, Validity, and Reliability of an Electronic Visual Analog Scale for Pain on a Touch Screen Tablet in Healthy Older Adults: A Clinical Trial

Background New technology for clinical data collection is rapidly evolving and may be useful for both researchers and clinicians; however, this new technology has not been tested for accuracy, reliability, or validity. Objective This study aims to test the accuracy of visual analog scale (VAS) for pain on a newly designed application on the iPad (iPadVAS) and measure the reliability and validity of iPadVAS compared to a paper copy (paperVAS). Methods Accuracy was determined by physically measuring an iPad scale on screen and comparing it to the results from the program, with a researcher collecting 101 data points. A total of 22 healthy community dwelling older adults were then recruited to test reliability and validity. Each participant completed 8 VAS (4 using each tool) in a randomized order. Reliability was measured using interclass correlation coefficient (ICC) and validity measured using Bland-Altman graphs and correlations. Results Of the measurements for accuracy, 64 results were identical, 2 results were manually measured as being 1 mm higher than the program, and 35 as 1 mm lower. Reliability for the iPadVAS was excellent with individual ICC 0.90 (95% CI 0.82-0.95) and averaged ICC 0.97 (95% CI 0.95-1.0) observed. Linear regression demonstrated a strong relationship with a small negative bias towards the iPad (−2.6, SD 5.0) with limits of agreement from −12.4 to 7.1. Conclusions The iPadVAS provides a convenient, user-friendly, and efficient way of collecting data from participants in measuring their current pain levels. It has potential use in documentation management and may encourage participatory healthcare.

Magnetic Phase Relations of RCo3

RCo3 compounds with rhombohedral structure have been synthesized, and their structural and magnetic properties have been investigated using powder X-ray diffraction and magnetic measurements. Rietveld technology was used to determine the crystal structures of RCo3. The lattice parameters and unit cell volumes decrease with increasing atomic numbers of R. Co-Co and R-Co bond lengths (BLs) were determined with Diamond Software according to the atomic positions. The rare earth dependence of magnetic phase diagram was studied systemically. Curie temperatures increase with increasing Co-Co and R-Co BLs in light rare earth regime and heavy rare earth regime. A modified magnetic valence model was used to investigate the magnetic moments of RCo3. The magnetic moment depends only on the total number of d and s-p, as well as f electrons, and not on the bandshape. The valence numbers of rare earth also affect the moments.
New HIV protease inhibitors for drug-resistant viruses

Several second-generation protease inhibitors have been developed over the last few years. These compounds have been used in preregistrative clinical trials or are currently in various Phases (I, II or III) of their progress towards use in HIV-1-infected patients. All drugs in this category have been designed in order to reach high plasma levels and possibly overcome the issue of cross-resistance among the compounds belonging to this class. Taking into account the rapid occurrence of protease inhibitor cross-resistance, clinicians who are treating patients living with HIV/AIDS will need new active protease inhibitors in the near future. These newly developed compounds will be the subject of our review.

This study provides an efficient algorithm for the meshfree radial point interpolation method on graphics hardware. The algorithm is based on the meshfree method called radial point interpolation method that enables strict imposition of Dirichlet boundary conditions. The method mainly consists of two processes: the discrete system assembly and its solving process. This paper presents an algorithm performing parallel computation of the two processes on graphics hardware.
Second-order Consensus of Multi-agent System with Dynamic Network Topology

This paper investigates second-order leaderless and leader-following consensus in multi-agent systems with dynamic network topologies, where the communication weights are determined by the inter-agent distances. With the proposed leaderless consensus protocol, the states of all agents are ensured to agree on the state of the mass center of the system. By the leader-following consensus algorithm based on pinning control, all agents are guaranteed to asymptotically follow the virtual leader. Numerical results are given to verify the theoretical analysis.
Low-Energy Extracorporeal Shock Wave Therapy as a Treatment for Medial Tibial Stress Syndrome

Background Medial tibial stress syndrome (MTSS) is a pain syndrome along the tibial origin of the tibialis posterior or soleus muscle. Extracorporeal shock wave therapy (SWT) is effective in numerous types of insertional pain syndromes. Hypothesis Shock wave therapy is an effective treatment for chronic MTSS. Study Design Cohort study; Level of evidence, 3. Methods Forty-seven consecutive subjects with chronic recalcitrant MTSS underwent a standardized home training program, and received repetitive low-energy radial SWT (2000 shocks; 2.5 bars of pressure, which is equal to 0.1 mJ/mm2; total energy flux density, 200 mJ/mm2; no local anesthesia) (treatment group). Forty-seven subjects with chronic recalcitrant MTSS were not treated with SWT, but underwent a standardized home training program only (control group). Evaluation was by change in numeric rating scale. Degree of recovery was measured on a 6-point Likert scale (subjects with a rating of completely recovered or much improved were rated as treatment success). Results One month, 4 months, and 15 months from baseline, success rates for the control and treatment groups according to the Likert scale were 13% and 30% (P < .001), 30% and 64% (P < .001), and 37% and 76% (P < .001), respectively. One month, 4 months, and 15 months from baseline, the mean numeric rating scale for the control and treatment groups were 7.3 and 5.8 (P < .001), 6.9 and 3.8 (P < .001), and 5.3 and 2.7 (P < .001), respectively. At 15 months from baseline, 40 of the 47 subjects in the treatment group had been able to return to their preferred sport at their preinjury level, as had 22 of the 47 control subjects. Conclusion Radial SWT as applied was an effective treatment for MTSS.
Energy Storage Battery Bank system to reduce peak demand for domestic consumers

In the generation of electricity it is always challenging to supply the varying demand in a day. As base load power plants cater the power demand throughout the day, the peak power plants have to be operated only during the high demand time. Since the running cost of peak load power plants are extremely high compared to base load plants, the suppliers are always trying to reduce the peak load using many techniques. As in pumped storage hydro power plants, energy storage systems can absorb energy during the off peak time and supply the energy back to the system during peak time. In this research, the objective was to find a system that virtually acts like a pumped storage power plant at consumers' premise. It was found that using a battery bank, the energy can be stored and supplied to the premise to reduce the peak load. The feasibility study of the proposed system has been carried out and the results shows the storage system can reduce the peak load at the consumer premise and hence make and impact to reduce the peak load in a utility as well. By making the peak load reduced, it was proposed to reduce the toxic gas emission of peak load power plants.
Analysis of Phase-Locking in Optoelectronic Microwave Oscillators Due to Small RF Signal Injection

In this paper, we analyze the phase-locking phenomenon in a single-loop optoelectronic microwave oscillator, when subjected to the influence of small radio-frequency (RF) signal. We derive the differential equations for the amplitude and phase variations in the oscillator. Using quasi-linear approximation, analytical expressions for the lock range and phase-shift after phase-locking are presented. In addition, beat frequency of the unlocked-driven optoelectronic oscillator (OEO) is obtained and the phase-locking dynamics of the driven oscillator is discussed. Also, the spectrum components of the pulled OEO is derived as a function of the frequency detuning, lock range, beat-frequency, and frequency-shift induced by the phase perturbation of the injection signal. It is shown that all the analytical closed-form expressions clearly demonstrate the phase-locking mechanism starting from the fast-beat state through the quasi-locked state to the locked state of the pulled OEO. Finally, the simulation results are given to validate the analytical results.

Patient and Nurse Experiences in a Rural Chronic Disease Management Program: A Qualitative Evaluation

Purpose: Rural status confounds chronic disease self-management. The purpose of this qualitative, descriptive study was to evaluate the nurse-led “Living Well” chronic disease management program reporting patient recruitment and retention issues since program initiation in 2013. The Chronic Care Model (CCM) was the guiding framework used to reinforce that interdisciplinary teams must have productive patient interactions for their program(s) to be sustainable. Primary Practice Setting: A rural, Midwest county clinic's chronic disease management program. Methodology and Sample: Observations, interviews, and within- and across-case coding were used. Patients' responses were analyzed to identify (1) reasons for recruitment and retention problems and (2) program elements that were viewed as successful or needing improvement. A convenience sample of 6 rural, English-speaking adults (65 years or older, with no severe cognitive impairment) with at least one chronic condition was recruited and interviewed. Results: Themes emerged related to nurse knowledge, availability, and value; peer support; overcoming barriers; adherence enhancement; and family/friends' involvement. Patients reported engagement in self-management activities because of program elements such as support groups and productive nurse–patient interactions. Interdisciplinary communication, commitment, and patient referral processes were identified as reasons for recruitment and retention issues. Implications for Case Management Practice: Findings substantiated that certain elements must be present and improved upon for future rural programs to be successful. Interdisciplinary communication may need to be improved to address recruitment and retention problems. It was clear from patient interviews that the nurse coordinators played a major role in patients' self-management adherence and overall satisfaction with the program. This is important to case management because results revealed the need for programs of this nature that incorporate the vital role of nurse coordinators and align with the CCM value of providing a supportive community health care resource for patients with chronic disease.
Retrovolution: HIV–Driven Evolution of Cellular Genes and Improvement of Anticancer Drug Activation

In evolution strategies aimed at isolating molecules with new functions, screening for the desired phenotype is generally performed in vitro or in bacteria. When the final goal of the strategy is the modification of the human cell, the mutants selected with these preliminary screenings may fail to confer the desired phenotype, due to the complex networks that regulate gene expression in higher eukaryotes. We developed a system where, by mimicking successive infection cycles with HIV-1 derived vectors containing the gene target of the evolution in their genome, libraries of gene mutants are generated in the human cell, where they can be directly screened. As a proof of concept we created a library of mutants of the human deoxycytidine kinase (dCK) gene, involved in the activation of nucleoside analogues used in cancer treatment, with the aim of isolating a variant sensitizing cancer cells to the chemotherapy compound Gemcitabine, to be used in gene therapy for anti-cancer approaches or as a poorly immunogenic negative selection marker for cell transplantation approaches. We describe the isolation of a dCK mutant, G12, inducing a 300-fold sensitization to Gemcitabine in cells originally resistant to the prodrug (Messa 10K), an effect 60 times stronger than the one induced by the wt enzyme. The phenotype is observed in different tumour cell lines irrespective of the insertion site of the transgene and is due to a change in specificity of the mutated kinase in favour of the nucleoside analogue. The mutations characterizing G12 are distant from the active site of the enzyme and are unpredictable on a rational basis, fully validating the pragmatic approach followed. Besides the potential interest of the G12 dCK variant for therapeutic purposes, the methodology developed is of interest for a large panel of applications in biotechnology and basic research.
Moving Targets Detection and Analysis on Multi-Look Polarimetric SAR Images using PWF Method

The motion of moving targets causes distortions in SAR image, which present a challenge on image interpretation. Comparing to stationary targets' signatures, signatures of moving target are distorted from azimuth displacement to smearing beyond detectability. In this paper, a moving target detection algorithm is proposed based on polarimetric whitening filter (PWF) as well as time-frequency (TF) analysis. An experiment is implemented using multi-look X-band PolSAR image acquired by PiSAR. Both moving target and stationary target are included in the image. Results shows PWF method and time-frequency analysis could be used detect moving targets as respected.
Power Allocation for AF Relaying Network under Channel Phase Misalignment

This paper studies both cooperative and noncooperative amplify-and-forward (AF) wireless relay strategies with power constraints at the source and at the relays. The main objective is to design jointly and iteratively the closed form of a source scaling factor and a relay amplifying matrix, based on the minimum mean square error (MMSE) criterion under the conditions of both no-channel and channel phase misalignments. With the derived optimal source scaling factors and relay amplifying matrices, impacts on the system performance of both no-channel and channel phase misalignment are investigated by presenting the bit error rate and cost function behavior. Finally, this paper presents the iterative algorithm to solve the constrained Lagrangian optimization problem with a low computational complexity.
Modeling guided waves propagating in bones with a multilayered model

This study focuses on modeling guided waves propagating in bones with a multilayered model to simulate the phenomenon of osteoporosis. Double layer bone phantoms with a layer of water simulating soft tissue are used to discuss the dispersion relation of guided waves. The theoretical model is based on recursive asymptotic stiffness matrix method. A laser ultrasound technique is used to measure the experiment data. This model is used to predict dispersion spectra associated with the thinning of cortical and increasing porosity in the progression of osteoporosis. Results of this study will help to improve the accuracy for osteoporosis diagnostics using ultrasonic technique based on guided waves.
Psychosocial telephone interventions for patients with cancer and survivors: a systematic review

Over one third of patients with cancer experience elevated psychosocial distress. As screening for distress becomes more common, the number of patients referred for psychosocial care will increase. Psychosocial telephone interventions are recommended as a convenient and exportable alternative to in‐person interventions addressing psychosocial distress. This study reviews the efficacy of randomized controlled trials (RCTs) of psychosocial telephone interventions for patients with cancer.
Reflections on the Opportunities and Challenges of Youth Engagement: Youth and Professional Perspectives

This paper documents the opportunities and challenges experienced by youth leaders and community agency partners in our community-based research project on youth engagement. Participants provided reflective statements, based on their experiences during the course of this multi-year project. Specifically, these insights focused on (a) youth-oriented and collaborative research processes (for example highlighting youth voice—“bottom-up process for youth by youth,” and co-learning and team work); (b) group dynamics (for example, common purpose, dealing with transformation, relationship and trust-building, and power issues); and (c) benefits for community youth-serving agencies and youth themselves , for example, capacity-building, grounded in youth experiences through participatory research, and knowledge translation and practical application—advancing research into action). The process of being involved in this research was coined an “amazing journey” to facilitate positive change and transformation within the youth and community partners. Understanding such youth engagement issues has implications for better supporting high-risk youth and their families in order to enhance the quality of their lives in a meaningful, sustainable way.
Cell and molecular biology of the incretin hormones glucagon-like peptide-I and glucose-dependent insulin releasing polypeptide.

I. Introduction THE presence of intestinal factors regulating the function of endocrine secretion from the pancreas was first described in 1906 by Moore and colleagues (1). The idea that humoral factors secreted from the gut might act in this way arose after the recognition of “secretin” as a regulator of pancreatic secretion. Later it became evident that the hypoglycemic intestinal factor(s) is/are not “secretin” and the names “incretin” and “duodenin” were introduced in the 1920s and 1930s to describe these putative mediators (2–4). For several decades the nature of this/these factor(s) remained largely unknown (5–8) and before the first incretin hormone was chemically characterized, several other hormones produced in the gastrointestinal tract were discovered. The connection between the gastrointestinal tract and the endocrine pancreas was shown in the 1960s when insulin became measurable in plasma. In these classic studies, the insulin response to oral glucose and intravenous glucose, resulting in nea.
What firm characteristics determine women ' s employment in manufacturing? Evidence from Bangladesh

Purpose – The purpose of this paper is to investigate the principal determinants of women’s employment in the manufacturing sector of Bangladesh using a firm-level panel data from the World Bank’s “Enterprise Survey” for the years 2007, 2011 and 2013. The paper sheds light on the demand-side factors, mainly firm-level characteristics, which also influence this decision. Design/methodology/approach – The authors estimate a fractional logit model to model a dependent variable that is limited by zero from below and one from above. Findings – The results indicate that firm size, whether medium or large, and firms’ export-oriented activities, have an important impact on women’s employment in the manufacturing sector in Bangladesh. Moreover, the authors find that women are significantly more likely to work in unskilled-labour-intensive industries within the manufacturing sector. Research limitations/implications – The research is limited to Bangladesh; however, much of the evidence presented here has implicatio.
Recognition of sport players' numbers using fast-color segmentation

This paper builds on a prior work for player detection, and proposes an efficient and effective method to distinguish among players based on the numbers printed on their jerseys. To extract the numbers, the dominant colors of the jersey are learnt during an initial phase and used to speed up the segmentation of the candidate digit regions. An additional set of criteria, considering the relative position and size (compared to the player bounding box) and the density (compared to the digit rectangular support) of the digit, are used to filter out the regions that obviously do not correspond to a digit. Once the plausible digit regions have been extracted, their recognition is based on feature-based classification. A number of original features are proposed to increase the robustness against digit appearance changes, resulting from the font thickness variability and from the deformations of the jersey during the game. Finally, the efficiency and the effectiveness of the proposed method are demonstrated on a real-life basketball dataset. It shows that the proposed segmentation runs about ten times faster than the mean-shift algorithm, but also outlines that the proposed additional features significantly increase the digit recognition accuracy. Despite significant deformations, 40% of the samples, that can be visually recognized as digits, are well classified as numbers. Out of these classified samples, more than 80% of them are correctly recognized. Besides, more than 95% of the samples, that are not numbers, are correctly identified as non-numbers.
