Authors: Kathirvelu K. Parkavi , Viswanathan B. 
Published: March 2017

<p>In solar energy conversion system harvesting of maximum energy is necessary in order to maximize the utilization of available energy. The maximum energy from the solar panel can be extracted by keeping solar panel in an optimum tilt angle. Various approaches are available to find optimum tilt condition of the solar panel. In this work two different positions of the panel such as fixed tilt, seasonal tilt were analyzed using isotropic and anisotropic models. Among the various models available in the above said broad category six models such as Liu-Jordan, Koronokis Model, Badescu model, Hay and Davis model, Reindel model, Hay&amp;Davis and Reindel &amp; Klucher combined model are incorperated to predict the monthly average of daily global solar irradiation of the inclined panels held in SASTRA University, Thanjavur (India) location. Statistical tests have been performed in order to evaluate the consequences predicted by the models with the experimental results. Finally a detailed comparison between fixed tilt and seasonal tilt of the panel has been carried out and the suitable model for this location is also suggested.</p>

Abstract
The role of earlier forecast errors on subsequent convection forecasts is evaluated for a northern Great Plains severe convective event on 11–12 June 2013 during the Mesoscale Predictability Experiment (MPEX) by applying the ensemble-based sensitivity technique to Weather Research and Forecasting (WRF) Model ensemble forecasts with explicit convection. This case was characterized by two distinct modes of convection located 150 km apart in western Nebraska and South Dakota, which formed on either side of an axis of high, lower-tropospheric equivalent potential temperature . Convection forecasts over both regions are found to be sensitive to the position of this axis. The convection in Nebraska is sensitive to the position of the western edge of the axis near an upstream dryline, which modulates the preconvective prior to the diurnal maximum. In contrast, the convection in South Dakota is sensitive to the position of the eastern edge of the axis near a cold front, which also modulates the preconvective in that location. The position of the axis is modulated by the positions of both upstream and downstream mid- to upper-tropospheric potential vorticity anomalies, and can be traced backward in time to the initial conditions. Dropsondes sampling the region prior to convective initiation indicate that ensemble members with better representations of upstream conditions in sensitive regions are associated with better convective forecasts over Nebraska.

Background Sleep problem is a common geriatric condition that can result in various outcomes, both physical and mental, that reduce quality of life. The studies regarding the prevalence and impact of insomnia on daily activities in Thailand in pre-elderly and elderly adults are few. Objectives The primary objective of this study was to determine the prevalence of insomnia among pre-elderly and elderly populations and the secondary objective was to study the impact of insomnia on their daily lives. Methods This study included the participants from the urban middle class in the pre-retirement age of 50 years or older adults who worked for Khon Kaen University (KKU), Khon Kaen, Thailand, and their elderly relatives. Information on baseline characteristics, sleep problems, and outcomes were collected. Descriptive analytical statistics were used to analyze baseline data. Multivariate analysis was used to analyze associated factors of the impact of insomnia. Results A total of 491 participants were recruited. The prevalence of insomnia was 60%. The significant consequences related to insomnia were feeling unrefreshed (adjusted odds ratio (AOD) 2.22, 95% confidence interval (CI) 1.44–3.04), daytime sleepiness (AOD 2.04, 95% CI 1.29–3.22), need for a sedative drug (AOD 4.23, 95% CI 2.09–8.55), depression (AOD 4.74, 95% CI 1.73–13), and impaired attention (AOD 2.29, 95% CI 1.52–3.45). Conclusions Insomnia was found in the majority of pre-elderly and elderly participants and resulted in several poor outcomes. Early detection of insomnia may prevent some inevitable outcomes.

Objectives Depression is one of the common mental health problems noticed in immigrants because of the experiences related to their resettlement which is the case for Somali population. Depression increases mortality, morbidity, disability, and costs of health care which can be controlled by screening depression in the primary care setting using a culturally and linguistically congruent screening tool. The aim of the current study is to translate the English PHQ-9 into Somali language using evidence-based translational methodology and establish psychometric properties of the Somali PHQ-9. Methods The initial validation of the Somali PHQ-9 was studied by comparing the original and back translation versions using the comparability and interpretability tool in a sample of 56 monolingual health care professionals. The reliability and validity of the Somali version were established by psychometric analysis in a sample of 47 bilingual health-care workers. Results Cronbach’s alpha was 0.79 for the Somali version with the inter-item correlation mean of 0.33 and item-to-total correlation mean in the range of 0.40–0.80 ( p < 0.01). Pearson correlation for the item-to-item correlation between English and Somali version was between 0.70 and 0.93 ( p < 0.01) with the paired t-test showing no significant difference between the item means. Conclusions The Somali PHQ-9 showed a good reliability, homogeneity, and internal consistency. The construct validity for the Somali PHQ-9 was also established showing that the Somali PHQ-9 has similar reliability and validity like the other translated versions of PHQ-9.

Published: March 2017

Background: Recommendations exist to encourage safe youth participation in sport. These recommendations include not specializing in 1 sport, limiting participation to less than 8 months per year, and limiting participation to fewer hours per week than a child’s age. However, limited evidence exists to support or refute these recommendations. Hypothesis: High levels of specialization will be associated with a history of injuries and especially overuse injuries, independent of age, sex, or weekly sport training hours. Athletes who exceed current sport volume recommendations will be more likely to have a history of injuries and overuse injuries. Study Design: Case-control study; Level of evidence, 3. Methods: Youth athletes (n = 2011; 989 female and 1022 male; 12-18 years of age) completed a questionnaire regarding their specialization status, yearly and weekly sport participation volume, and injury history. Specialization was classified as low, moderate, or high using a previously utilized 3-point scale. Athletes were classified into groups based on either meeting or exceeding current volume recommendations (months per year and hours per week). Odds ratios (ORs) and 95% CIs were calculated to investigate associations of specialization and volume of participation with a history of sport-related injuries in the past year ( P ≤ .05). Results: Highly specialized athletes were more likely to report a previous injury of any kind ( P < .001; OR, 1.59; 95% CI, 1.26-2.02) or an overuse injury ( P = .011; OR, 1.45; 95% CI, 1.07-1.99) in the previous year compared with athletes in the low specialization group. Athletes who played their primary sport more than 8 months of the year were more likely to report an upper extremity overuse injury ( P = .04; OR, 1.68; 95% CI, 1.06-2.80) or a lower extremity overuse injury ( P = .001; OR, 1.66; 95% CI, 1.22-2.30). Athletes who participated in their primary sport for more hours per week than their age (ie, a 16-year-old athlete who participated in his or her primary sport for more than 16 h/wk) were more likely to report an injury of any type ( P = .001; OR, 1.34; 95% CI, 1.12-1.61) in the previous year. Conclusion: High levels of specialization were associated with a history of injuries, independent of age, sex, and weekly organized sport volume. Athletes who exceeded volume recommendations were more likely to have a history of overuse injuries. Clinical Relevance: Parents and youth athletes should be aware of the risks of specialization and excessive sport volume to maximize safe sport participation.

Authors: Kadhum M. , Smock E. , Khan A. , Fleming A. 
Published: March 2017

Radiotherapy has been advocated as an alternative treatment in early Dupuytren’s disease. We have systematically reviewed the evidence on the use of radiotherapy in Dupuytren’s disease. Only six articles met a minimum set standard, five of which were retrospective cohort studies and one a randomized controlled study. A total of 770 Dupuytren’s hands, nearly all with Tubiana stage 0–1 disease, were irradiated with an average 30 Gy. Disease regression ranged from 0%–56%, stability from 14%–98% and progression from 2%–86%. Salvage surgery was successful in all cases of disease progression post-radiotherapy. There were no reports of adverse wound healing problems associated with such surgery or radiotherapy-associated malignancy. On balance, radiotherapy should be considered an unproven treatment for early Dupuytren’s disease due to a scarce evidence base and unknown long-term adverse effects. Well-designed randomized controlled studies are required to confirm the benefits of radiotherapy treatment. Level of evidence: II

Published: March 2017

Background and importance Intraorbital arteriovenous fistulas (IOAVFs) are rare and cause eye redness, exophthalmos, blurry vision and bruit. Whereas in the past they were treated conservatively, surgically or transarterially, recent developments in transvenous embolization have improved their treatment. In this paper the authors report three cases of IOAVFs treated endovascularly and review the evolution of treatment options. Methods Three cases of purely IOAVF enrolled in our center were reported and a PubMed literature search was performed using “pure intraorbital arteriovenous fistula” and “arteriovenous fistula of the optic nerve sheath.” A total of 21 papers were reviewed in full, focusing primarily on the treatment and outcomes. Results A total of 26 patients were obtained, including our three patients and 23 patients reported in the literature. In nine patients treated conservatively, four spontaneous occlusions, one visual deterioration and four cases with unknown outcome were reported. In another 18 patients, 29 therapies (including five surgical treatment, 11 transarterial embolizations and 13 transvenous embolizations) were attempted and resulted in 12 cures, five visual deteriorations and one without reported outcome. More recently, transvenous embolization has become the mainstay of IOAVF treatment. Of the 21 patients assessed between 2000 and 2013, a transvenous approach was attempted in 13 patients; nine patients were cured without any adverse events. Conclusion Development and improvement of transvenous techniques are found to be safe and effective for patients with IOAVF.

Abstract

Background
Multiple iterations of chimeric antigen receptors (CARs) have been developed, mainly focusing on intracellular signaling modules. However, the effect of non-signaling extracellular modules on the expansion and therapeutic efficacy of CARs remains largely undefined.

Methods
We generated two versions of CAR vectors, with or without a hinge domain, targeting CD19, mesothelin, PSCA, MUC1, and HER2, respectively. Then, we systematically compared the effect of the hinge domains on the growth kinetics, cytokine production, and cytotoxicity of CAR T cells in vitro and in vivo.

Results
During in vitro culture period, the percentages and absolute numbers of T cells expressing the CARs containing a hinge domain continuously increased, mainly through the promotion of CD4+ CAR T cell expansion, regardless of the single-chain variable fragment (scFv). In vitro migration assay showed that the hinges enhanced CAR T cells migratory capacity. The T cells expressing anti-CD19 CARs with or without a hinge had similar antitumor capacities in vivo, whereas the T cells expressing anti-mesothelin CARs containing a hinge domain showed enhanced antitumor activities.

Conclusions
Hence, our results demonstrate that a hinge contributes to CAR T cell expansion and is capable of increasing the antitumor efficacy of some specific CAR T cells. Our results suggest potential novel strategies in CAR vector design.

Published: March 2017

AbstractThe article considers the model and method of converged computing and storage to create SCADA systems based on wireless networks for the energy industry. Computing power of modern wireless sensor network nodes allow the transfer to them some operations sensor data mining and offload the dispatching data centre servers. This fog computing model is used for the aggregation of primary data, forecast trends controlled variables as well as to warn about abnormal and emergency situations on distributed SCADA systems objects. Large arrays of sensor data, integral indicators and heterogeneous information from other sources (e.g., weather stations, security and fire alarm systems, video surveillance systems, etc.) is more appropriate to process via GRID computing model. GRID computing model has three-tier architecture, which includes the main server at the first level, a cluster of servers at the second level, and a lot of GPU video card with support for Compute Unified Device Architecture at the third level. The model of cloud computing and cloud storage today is the basis for the accumulation of the results of data mining and knowledge discovery. Means of communication and remote access can solve the problem of intellectual processing and visualization of information with elements of augmented reality and geo-information technologies within the framework of mobile computing model. The implementation of these four computing models for the operation of components of SCADA system is the convergent approach to distributed sensor data processing, which is discussed in the article.
Fault visualization and identification in fault seismic attribute volumes: Implications for fault geometric characterization
Authors: Libak Audun , Alaei Behzad , Torabi Anita 
Published: March 2017

Fault seismic attribute volumes (such as volumetric coherence and curvature) represent an efficient and objective way to visualize and identify faults in seismic cubes. Fault geometric attributes such as length, height, and fault segmentation can be extracted from such fault seismic attribute volumes. We evaluate the strengths and pitfalls of using coherence volumes for characterization of fault geometry. The results are obtained using a database from the Barents Sea, which contains 35 3D seismic cubes, together with conceptual synthetic seismic models. A high signal-to-noise ratio is a requirement for the extraction of accurate fault geometric data. Noise attenuation methods improve fault visualization, but our results indicate that the effect of noise attenuation on the extracted fault geometric attributes is only clear in areas of low signal-to-noise ratios. The choice of coherence algorithm is important when extracting fault length data. Semblance-based coherence performs better than gradient structure tensor-based coherence in low-displacement areas near the fault tips, and it produces more accurate fault length data. Faults can appear segmented in coherence volumes if relatively similar reflectors are juxtaposed across a fault. In such areas, it is important that the interpreter does not overlook the fault. The size of the analysis window used in coherence calculations controls the resolution and continuity of the imaged faults. Our results support an optimal temporal window size of one to two times the dominant period of the seismic data (typically 7–17 samples in conventional 4 ms sampled 3D seismic data). Larger temporal window sizes can result in an overestimation of fault height, especially for small faults. A large spatial window can smear out segmentation along the fault and make the fault traces wider. Even though a large spatial window can have some positive effects, we recommend using a relatively small spatial window (five traces) when extracting subtle fault geometric attributes.

Published: March 2017

Purpose: Many patients with breast cancer are treated for other conditions and experience polypharmacy with multiple concurrent medications. Our aim was to evaluate polypharmacy in relation to adherence to adjuvant endocrine therapy (AET) in breast cancer. Methods: We conducted a retrospective cohort study of women with incident, invasive breast cancer initiating AET (tamoxifen, letrozole, anastrozole, exemestane) between 2009 and 2013 in the Truven Health MarketScan Database. Polypharmacy and pill burden were measured for commonly used concurrent medications, including lipid-lowering drugs, antihypertensives, oral diabetes medications, insulin analogs, antidepressants, anxiolytics/antipsychotics, and opioid-containing analgesics. Polypharmacy was defined as frequent use (three or more dispensings) of a given medication class and by pill burden (total dispensings). Medication possession ratios (MPR) were estimated for subsequent 12-month intervals. Multivariable generalized estimating equation models were used to calculate odds ratios (ORs) and robust 95% CIs for associations with AET adherence (MPR ≥ 0.80). Results: Among 40,009 women, 74% were adherent in year +1 and continued to have high mean adherence (MPR = 0.79) among those continuing AET through year +3. Increasing polypharmacy ( P < .001) and pill burden ( P < .001) were associated with greater adherence, but effects differed by medication class. Frequent use of lipid-lowering drugs (OR, 1.42; 95% CI, 1.36 to 1.49) and antihypertensives (OR, 1.15; 95% CI, 1.10 to 1.20) were associated with higher odds of adherence; frequent use of opioid-containing analgesics (OR, 0.80; 95% CI, 0.77 to 0.83), anxiolytics/antipsychotics (OR, 0.95; 95% CI, 0.91 to 0.99), antidepressants (OR, 0.85; 95% CI, 0.82 to 0.89), and insulin therapy (OR, 0.82; 95% CI, 0.72 to 0.95) were associated with lower odds of adherence. Conclusion: Associations between polypharmacy and adherence in breast cancer may be better characterized by understanding specific classes of medications used concurrently. Comprehensive medication therapy management, including ongoing pain evaluation and psychoactive therapies, is warranted.
Marketing the Southwest: Modernism, the Fred Harvey Company, and the Indian Detour
Authors: Oliphant Elizabeth Lloyd 
Published: March 2017

AbstractThis essay analyzes the mutually influential relationship between literary modernism and tourism as those two interests converged around the US Southwest in the early twentieth century. Modernist writers were drawn to the Southwest’s folk and Native American cultures, viewing them as potent sources of artistic inspiration. However, those same modernists had a significant hand in shaping the region’s burgeoning tourism industry. These surprising commercial collaborations offer the opportunity for a more nuanced understanding of modernism’s relationship to commercial work. The essay focuses on a promotional brochure produced for the Harvey Company’s sightseeing “Indian Detour” experience. The brochure, distributed to passengers on the Indian Detour, featured essays and poetry contributed by modernist writers including Witter Bynner, Alice Corbin Henderson, and Harriet Monroe. The essay also brings to light the connections between this promotional brochure and back issues of Monroe’s Poetry: A Magazine of Verse, further underscoring the close ties between commercial tourism and literary modernism.
An Affinity of Hammers
Authors: Ahmed Sara 
Published: March 2017

Abstract
This article offers a critique of the claim made by trans-exclusionary radical feminists that transphobia is being misused as a way of silencing or censoring critical feminist speech. The article suggests that transphobia works as a rebuttal system, one that, in demanding trans people provide evidence of their existence, is experienced as a hammering, a constant chipping away at trans existence. The article suggests that transphobia within feminism needs to be understood in relation to cis privilege: not having to come into contact with this hammering. It offers a model of political hope resting on “an affinity of hammers”; that is, affinity can be acquired through the work of chipping away at the system.
Francophone Trans/Feminisms
Authors: Baril Alexandre 
Published: March 2017

Abstract
In this essay, the author draws on his experience as a trans, francophone, feminist researcher to share his reflections on the difficulties encountered within francophone contexts in the development of knowledge that moves beyond what the TSQ editors call “the familiar and overly simplistic dichotomy often drawn between an exclusionary transphobic feminism and an inclusive trans-affirming feminism.” Without reducing the work of the few francophone researchers interested in trans/feminisms, including the author's, to the fight against exclusionary, transphobic feminist theories, policies, and practices, he demonstrates how problematic it is to articulate their work in terms other than the exclusion/inclusion of trans people within feminism. The author offers as a case study the 2015 Seventh International Conference of Francophone Feminist Research, currently the world's most important francophone feminist conference, to illustrate the near total silence on trans issues that reigns in francophone feminist communities.
Of Huachafería, Así, and M’ E Mati
Authors: DiPietro Pedro Javier 
Published: March 2017

Abstract
Trans, transing, queer, and queering are typically represented as sharing in the antinormalizing labor that concerns material bodies. In the vein of decolonial feminism, this essay looks at three renderings of transing methodologies for what they teach us about: the geopolitical tension between transing and queering; genealogies of feminist, gay and lesbian, queer, and trans studies; the collusion of Euro-centered thought with trans research; and the social ontology of transing embodiments.
