In-memory key-value stores play a critical role in data processing to provide high throughput and low latency data accesses. In-memory key-value stores have several unique properties that include (1) data intensive operations demanding high memory bandwidth for fast data accesses, (2) high data parallelism and simple computing operations demanding many slim parallel computing units, and (3) a large working set. As data volume continues to increase, our experiments show that conventional and general-purpose multicore systems are increasingly mismatched to the special properties of key-value stores because they do not provide massive data parallelism and high memory bandwidth; the powerful but the limited number of computing cores do not satisfy the demand of the unique data processing task; and the cache hierarchy may not well benefit to the large working set.
In this paper, we make a strong case for GPUs to serve as special-purpose devices to greatly accelerate the operations of in-memory key-value stores. Specifically, we present the design and implementation of Mega-KV, a GPU-based in-memory key-value store system that achieves high performance and high throughput. Effectively utilizing the high memory bandwidth and latency hiding capability of GPUs, Mega-KV provides fast data accesses and significantly boosts overall performance. Running on a commodity PC installed with two CPUs and two GPUs, Mega-KV can process up to 160+ million key-value operations per second, which is 1.4-2.8 times as fast as the state-of-the-art key-value store system on a conventional CPU-based platform.

AbstractTaking multiple anthropometric measurements for the description of body proportions in an accurate way is a time-consuming procedure that requires specific tools and skills. This is why we developed an alternative method based on digital photography for taking these measurements which is faster and easier to use, to make anthropometry more user-friendly and approachable to paediatricians.We conducted a cross-sectional study in 54 children between 2 and 18 years of age. We compared manual measurements with photogrammetric measurements to validate our method.Inter-observer correlations of all measurements are ≥0.96 and mean differences are 0.3–0.9 cm, except for arm span. Comparison of manual to photogrammetric measurements shows mean differences of 0.6–1.3 cm, with correlations ≥0.92, except for sitting height and arm span. Correlations of ratios between methods are height/sitting height (Photogrammetric anthropometry is faster, easier to use and provides the paediatrician with more flexibility as taking the digital photographs and performing the analysis are separated.

Job characteristics and musculoskeletal pain among shift workers of a poultry processing plant in Southern Brazil: Dânia Barro, et al. Postgraduate Program in Collective Health, University of Vale do Rio dos Sinos, BrazilObjectiveThe purpose of this study was to evaluate the association between job characteristics and musculoskeletal pain among shift workers employed at a 24‐hour poultry processing plant in Southern Brazil.MethodsThis was a cross‐sectional study of 1,103 production line workers aged 18−52 years. The job characteristics of interest were shift (day/night), shift duration, and plant sector ambient temperature. Musculoskeletal pain was defined as self‐reported occupational‐related pain in the upper or lower extremities and trunk, occurring often or always, during the last 12 months.ResultsThe mean (SD) participant age was 30.8 (8.5) years, and 65.7% of participants were women. The prevalence of musculoskeletal pain was greater among female participants than male participants. After adjustment for job characteristics and potential confounders, the prevalence ratios (PR) of lower extremity musculoskeletal pain among female workers employed in extreme‐temperature conditions those working the night shift, and those who had been working longer on the same shift were 1.75 (95% CI 1.12, 2.71), 1.69 (95% CI 1.05, 2.70), and 1.64 (95% CI 1.03, 2.62), respectively. In male workers, only extreme‐temperature conditions showed a significant association with lower extremity musculoskeletal pain (PR=2.17; 95% CI 1.12, 4.22) after adjustment analysis.ConclusionsThese findings suggest a need for implementation of measures to mitigate the damage caused by nighttime work and by working under extreme temperature conditions, especially among female shift workers, such as changing positions frequently during work and implementation of rest breaks and a workplace exercise program, so as to improve worker quality of life.
White Rain: 9/11 and American Fiction
Authors: Nadel Ira 
Published: July 2015

Abstract: How have authors responded to 9/11? This article examines a variety of reactions in light of the need to construct a dominant narrative necessary to restore a sense of security and understanding. But no single work or group of works has so far managed to trump the tragedy, and a void remains. The phrase “white rain” expresses the blizzard of paper generated by authors attempting to make sense of the event. Authors as diverse as John Updike, Don DeLillo, Frédéric Beigbeder, Jonathan Safran Foer, and Thomas Pynchon are the focus of the analysis here, showing how newly opened textual spaces are filled with works alternating between history and fiction. Of particular importance is the role of film, the importance of fear, and the symbol of flags in evaluating the process of recovery. Of particular note is the unease that characterizes the reaction of writers to the challenge they face: how to unite 9/11 as it exists in our cultural imagination with the event itself. That is the new task of literature in the post-9/11 age which, ironically, seems to require conflict or catastrophe for its inspiration.
An Immersed Interface Method for Axisymmetric Electrohydrodynamic Simulations in Stokes flow

Published: July 2015

AbstractA numerical scheme based on the immersed interface method (IIM) is developed to simulate the dynamics of an axisymmetric viscous drop under an electric field. In this work, the IIM is used to solve both the fluid velocity field and the electric potential field. Detailed numerical studies on the numerical scheme show a second-order convergence. Moreover, our numerical scheme is validated by the good agreement with previous analytical models, and numerical results from the boundary integral simulations. Our method can be extended to Navier-Stokes fluid flow with nonlinear inertia effects.
Excitatory and inhibitory innervation of the mouse orofacial motor nuclei: A stereological study
Authors: Faunes Macarena , Oñate‐Ponce Alejandro , Fernández‐Collemann Sara , Henny Pablo 
Published: July 2015

AbstractNeurons in the trigeminal (Mo5), facial (Mo7), ambiguus (Amb), and hypoglossal (Mo12) motor nuclei innervate jaw, facial, pharynx/larynx/esophagus, and tongue muscles, respectively. They are essential for movements subserving feeding, exploration of the environment, and social communication. These neurons are largely controlled by sensory afferents and premotor neurons of the reticular formation, where central pattern generator circuits controlling orofacial movements are located. To provide a description of the orofacial nuclei of the adult mouse and to ascertain the influence of excitatory and inhibitory afferents upon them, we used stereology to estimate the number of motoneurons as well as of varicosities immunopositive for glutamate (VGluT1+, VGluT2+) and GABA/glycine (known as VIAAT+ or VGAT+) vesicular transporters in the Mo5, Mo7, Amb, and Mo12. Mo5, Mo7, Amb, and Mo12 contain ∼1,000, ∼3,000, ∼600, and ∼1,700 cells, respectively. VGluT1+, VGluT2+, and VIAAT+ varicosities respectively represent: 28%, 41%, and 31% in Mo5; 2%, 49%, and 49% in Mo7; 12%, 42%, and 46% in Amb; and 4%, 54%, and 42% in Mo12. The Mo5 jaw‐closing subdivision shows the highest VGluT1+ innervation. Noticeably, the VGluT2+ and VIAAT+ varicosity density in Mo7 is 5‐fold higher than in Mo5 and 10‐fold higher than in Amb and Mo12. The high density of terminals in Mo7 likely reflects the convergence and integration of numerous inputs to motoneurons subserving the wide range of complex behaviors to which this nucleus contributes. Also, somatic versus neuropil location of varicosities suggests that most of these afferents are integrated in the dendritic trees of Mo7 neurons. J. Comp.

Published: July 2015

The purpose of this work was to evaluate the fatty acid levels and lipolysis of dry‐cured loins obtained from the native pig breed Chato murciano during processing to improve the processing technology. The fatty acid composition of neutral lipids (NL), polar lipids (PL), and free fatty acids (FFA) was analyzed in a gas chromatograph equipped with a flame ionization detector. The NL and PL contents decreased by 45 and 75%, respectively, confirming that PL was the fraction most affected by lipolysis. This decrease resulted in a higher level of FFA (80.26%). The concentrations of all the NL and PL fatty acids decreased and the FFA increased (except C14:0 and C20:0). The most affected were C18:2, C18:3, and C20:4, decreasing in NL and PL and increasing in FFA. The concentrations of the different groups of fatty acids depended on the lipid fraction. Thus, the concentrations of the groups of fatty acids were MUFA > SFA > PUFA in NL; SFA > PUFA = MUFA in PL, and MUFA > PUFA = SFA in FFA, at day 60 of processing. Chato murciano dry‐cured loin is characterized by a high MUFA concentration (mainly C18:1) in the NL and FFA fractions, which agrees with the findings made in other native pig breeds.Practical applications: Characterization of the Chato murciano native pig breed is essential if the processing of meat products of high commercial value is to be improved and to ensure the genuine nature of products. Besides, it is widely held that the consumption of products derived from native pig breeds should not only satisfy consumer demands, but also promote the development of areas where these breeds originate. Previous works described the sensory quality of Chato murciano dry‐cured loin and ham, while greater knowledge of fatty acid composition and lipolysis is necessary. The results obtained may help ascertain the most suitable conditions for processing. Confirmation that Chato murciano dry‐cured loin is a significant source of MUFA compared with the same products obtained from commercial crossbreed genotypes of pigs would increase the attraction of using the breed to obtain derived products.Evolution of SFA, MUFA and PUFA in neutral lipids (NL), polar lipids (PL), and free fatty acids (FFA) of Chato murciano dry‐cured loin at different days of processing.

Published: July 2015

Objectives/HypothesisTo determine the otolaryngology needs in a free clinic providing care to medically indigent patients, as perceived by the patients and health care providers.Study DesignCross‐sectional survey.MethodsA survey was administered to patients and health care providers of a free clinic from September 2014 through January 2015 in an urban, inner‐city location.ResultsOne hundred and thirty‐seven patients (35.8% male, age 50.8 ± 13.0 years) completed the survey. Mean household income was $29,838 ± $10,425; 32.1% spoke English; 54.7% were employed; 10.2% had health insurance; and 37.2% had seen a primary care provider outside of the free clinic. The top three otolaryngology symptoms among patients were sleep apnea/snoring (39.4%), heartburn/reflux (30.7%), and dizziness (29.9%). Eleven health care providers (45% male, age 50.5 ± 15.3 years, 63.6% physician, 36% nurse) completed the survey. Providers perceived the following otolaryngology complaints as the most prevalent, in descending order: cough, nasal congestion, reflux/heartburn, sore throat, and ear infection/otalgia. Providers felt that sleep apnea and hearing loss were the less common otolaryngology complaints, whereas surveyed patients indicated these symptoms with high frequency. The most requested diagnostic tool among patients and providers was chest X‐rays.ConclusionThere are unmet otolaryngology needs in a free clinic. Medically indigent patients have significant barriers to accessing health care. Patient and provider perceptions of top otolaryngology complaints differed, but both identified access to chest X‐rays as a major unmet need. Knowledge of patient perceptions may help providers elicit the breadth of otolaryngology complaints.Level of Evidence4. Laryngoscope, 126:1321–1326, 2016

AbstractBackgroundThe pathophysiology of cervical dystonia is poorly understood. Increased brain iron deposition has been described in different movement disorders. Our aim was to investigate brain iron content in patients with cervical dystonia, using R2* relaxation rate, a validated MRI marker of brain iron level.MethodsTwelve female patients with primary focal cervical dystonia (mean age: 45.4 ± 8.0 years) and 12 age‐matched healthy female subjects (mean age: 45.0 ± 8.0 years) underwent 3T MRI to obtain regional R2* relaxation rates of the thalamus, caudate nucleus, putamen, and globus pallidus (GP). Regions of interest were delineated automatically on T1‐weighted MRIs.ResultsR2* values in the putamen were positively correlated with age. Patients with cervical dystonia showed elevated R2* values in the GP.ConclusionsThis pilot study provides the first quantitative support for increased brain iron deposition in cervical dystonia. Further studies are needed to explore the implications of this finding.
On one-loop corrections in the standard model effective field theory; the Γ(h → γγ) case
Authors: Hartmann Christine , Trott Michael 
Published: July 2015

AbstractWe calculate one loop contributions to Γ(h→γγ) from higher dimensional operators in the Standard Model Effective Field Theory (SMEFT). Some technical challenges related to determining Electroweak one loop “finite terms” are discussed and overcome. Although we restrict our attention to Γ(h→γγ), several developments we report have broad implications. Firstly, the running of the vacuum expectation value (vev) modifies the log(μ) dependence of processes in a manner that is not captured in some past SMEFT Renormalization Group (RG) calculations. Secondly, higher dimensional operators can source ghost interactions inRξgauges due to a modified gauge fixing procedure. Lastly, higher dimensional operators can contribute with pure finite terms at one loop in a manner that is not anticipated in a RG analysis. These results cast recent speculation on the nature of one loop corrections in the SMEFT in an entirely new light.
Effects of Reading Instruction on Learning Outcomes in Social Studies: A Synthesis of Quantitative Research
Authors: McCulley Lisa V. , Osman David J. 
Published: July 2015

Quantitative research studies examining the effects of literacy instruction set in social studies classrooms (grades 6-12) on students’ academic content learning and reading comprehension are synthesized using meta-analytic techniques. An extensive search of the scholarly literature between 1983 and 2013 yielded a total of twelve intervention studies that provided literacy instruction to secondary students within social studies classes and quantitatively measured content learning outcomes, reading comprehension, or both. Findings revealed that content learning outcomes were consistently improved with instruction that included text-processing activities such as summarizing and generating questions. While many social studies teachers do not provide explicit reading supports, in part because they perceive that the time needed to do so is prohibitive, the findings of this synthesis suggest that sound reading practices hold promise as a means through which teachers can help students better access social studies content, thus improving student learning outcomes. More rigorous quantitative research is needed to further understand the causal effects of literacy practices in social studies settings. Highlights • Literacy instruction supports both reading comprehension and academic content • Literacy instruction does not negatively affect content knowledge acquisition. • Few studies investigate the effects of literacy instruction in social studies. • More research is needed to explore the effects of literacy instruction in social studies.
High Stakes and Persistent Challenges – A Rejoinder to Klabbers and Augsberg
Authors: HOLTERMANN JAKOB V. H. , MADSEN MIKAEL RASK 
Published: July 2015

AbstractIn this separate rejoinder to Jan Klabbers' and Ino Augsberg's comments to the articles in the symposium on New Legal Realism in International Law (Leiden Journal of International Law, Volume 28:2, 2015), we respond from the point of view of the European New Legal Realism (ENLR) as propounded in our initial contribution to the symposium. Agreeing with Ingo Venzke who wrote in his introduction to the symposium that ‘stakes are high’ in the debate over international law and methodology, we argue that both Klabbers and Augsberg, each in their own way, fail to take sufficiently seriously the ENLR challenge to doctrinal scholarship. We argue that Klabbers underestimates the evergreen and persistent character of this challenge when he portrays the current push for New Legal Realism as merely a whimsy fashion wave. And we argue that Augsberg's essentially Kelsenian defence of doctrinal scholarship is insufficiently robust because it inherits the excess epistemological liberalism of its underlying Neo-Kantianism.

BackgroundThe depth and breadth of problems related to depressive symptomatology and optimal treatment outcomes, including medication treatment adherence, have long been documented in the literature. Missing are clear explanations as to what factors and patient characteristics may account for lack of medication treatment adherence.ObjectivesThe two objectives of the current study were to examine the predictive strength of depression, patient characteristics, and patient attachment style regarding medication treatment adherence and to consider the extent to which attachment styles mediate the relation between depression and medication treatment adherence.MethodParticipants in the present study were 237 racially diverse American primary care patients with a diagnosis of hypertension who were participants in a clinical trial. Depression, patient characteristics, attachment style, and medication treatment adherence were assessed.ResultsPartly consistent with our four hypotheses, the following results were found: (a) Black American, younger, never married, and poorer patients had lower medication treatment adherence (b) depression was significantly associated with lower self-reported medication adherence; (c) insecure–dismissing attachment style was related to lower medication adherence; and (d) insecure–dismissing attachment style mediates the relation between depression and medication treatment adherence by exacerbating the negative association.ConclusionPhysicians and other primary care providers should consider how depressive symptomatology, patient characteristics, and attachment style may inform the treatment plans they put forward and the extent to which patients may adhere to those treatment plans.

Published: July 2015

BackgroundOsteoarthritis (OA) is a common condition expected to be the fourth leading cause of disability by the year 2020. Treatment with non-steroidal anti-inflammatory drugs is problematic in older adults (&gt;75 years) where the presence of comorbidities is more prevalent. Exercise has been recommended irrespective of age and comorbidity. The purpose of this project was to develop a combined exercise and self-management intervention to help older adults with OA to manage their comorbidities.MethodsLiterature reviews were conducted to inform the development of an intervention followed by a pilot study to assess feasibility and test outcome measures. Participant interviews and session observation were used to evaluate the pilot study.ResultsEvidence from the literature reviews suggested that a combined intervention consisting of behavioural change/self-management education and exercise was the most appropriate. Each component was developed and then tested as a combined package in a pilot study which comprised 12 sessions delivered over six weeks. Four males and six females aged between 75 and 92 years took part. The average attendance was 89%. Most participants reported some benefit and satisfaction with the programme along with changes in physical ability. The majority of participants continued with some form of exercise at three months.ConclusionThe intervention was well received and has encouraged 80% of participants to continue exercising after the programme. The small but positive changes seen in comorbidities, benefit of the intervention, satisfaction and general health are promising. Randomised controlled trial evidence of effectiveness and cost effectiveness is needed before such interventions can be recommended.
