A new bio-inspired, population-level approach to the socioeconomic evolution of dynamic spectrum access services
Authors: Horvath Denis , Gazda Juraj , Brutovsky Branislav
Published: March 2017

Evolutionary species and quasispecies models provide the universal and flexible basis for a large-scale description of the dynamics of evolutionary systems, which can be built conceived as a constraint satisfaction dynamics. It represents a general framework to design and study many novel, technologically contemporary models and their variants. Here, we apply the classical quasispecies concept to model the emerging dynamic spectrum access (DSA) markets. The theory describes the mechanisms of mimetic transfer, competitive interactions between socioeconomic strata of the end-users, their perception of the utility and inter-operator switching in the variable technological environments of the operators offering the wireless spectrum services. The algorithmization and numerical modeling demonstrate the long-term evolutionary socioeconomic changes which reflect the end-user preferences and results of the majorization of their irrational decisions in the same manner as the prevailing tendencies which are embodied in the efficient market hypothesis.
TEMPERATURE-DEPENDENT EFFECT OF BORIC ACID ADDITIVE ON SURFACE ROUGHNESS AND WEAR RATE
Authors: EKİNCİ ŞERAFETTIN
Published: March 2017

Wear and friction hold an important place in engineering. Currently, scientific societies are struggling to control wear by means of studies on lubricants. Boric acid constitutes an important alternative with its good tribological properties similar to MO2S and graphite alongside with low environmental impacts. Boric acid can be used as a solid lubricant itself whereas it can be added or blended into mineral oils in order to yield better mechanical and tribological properties such as low shear stress due to the lamellar structure and low friction, wear and surface roughness rates. In this study, distinguishing from the literature, boric acid addition effect considering the temperature was investigated for the conventional ranges of internal combustion engines. Surface roughness, wear and friction coefficient values were used in order to determine tribological properties of boric acid as an environmentally friendly additive and mineral oil mixture in the present study. Wear experiments were conducted with a ball on disc experimental setup immersed in an oil reservoir at room temperature, 50[Formula: see text]C and 80[Formula: see text]C. The evolution of both the friction coefficient and wear behavior was determined under 10[Formula: see text]N load, at 2[Formula: see text]m/s sliding velocity and a total sliding distance of 9000[Formula: see text]m. Surface roughness was determined using atomic-force microscopy (AFM). Wear rate was calculated utilizing scanning electron microscope (SEM) visuals and data. The test results showed that wear resistance increased as the temperature increased, and friction coefficient decreased due to the presence of boric acid additive.

Published: March 2017

The paper considers a general semi-Markov model for limit order books with two states that incorporates price changes that are not fixed to one tick. Furthermore, we introduce an even more general case of the semi-Markov model for limit order books that incorporates an arbitrary number of states for the price changes. For both cases, the justifications, diffusion limits, implementations and numerical results are presented for different limit order book data: Apple, Amazon, Google, Microsoft, Intel on 21 June 2012 and Cisco, Facebook, Intel, Liberty Global, Liberty Interactive, Microsoft, Vodafone from 3 November 2014 to 7 November 2014.

Rebalancing static super-replications
Authors: Takahashi Akihiko , Tsuzuki Yukihiro
Published: March 2017

This paper proposes a trading strategy that dynamically rebalances static super-replicating portfolios, which is very useful for both investment and hedging strategies. In order to investigate general properties of the strategy, we derive the Doob–Meyer decomposition for the value process without any specifications of models under the continuous processes of the underlying variables. In particular, we find that the increasing part of the decomposition characterizes the performance of the strategy. Also, we obtain more concrete features for cross-currency and one-touch options based on our general framework. Moreover, numerical examples for cross-currency options demonstrate the effectiveness of our strategy for investment and hedging.
Diffusion Controlled Model of Opinion Dynamics
Authors: Chandra Anjan Kumar , Basu Abhik
Published: March 2017

We have studied the effect of diffusion controlled opinion dynamics on a ring lattice where agents are placed on a fraction of sites. We have chosen the diffusion on a circular ring as a simple model to study emphasizing on the fact that agents approach their nearest neighbor for exchanging opinion. The agents execute simple exclusion process (SEP) on the ring and exchange opinion with neighboring agents according to a fixed rule. Our study shows that as agent density decreases, higher conviction power is necessary to create consensus. We have also investigated the nature of active-to-absorbing state phase transition for various densities and found that there are two universality classes for density [Formula: see text] and [Formula: see text].
Modeling Through Latent Variables
Authors: Verbeke Geert , Molenberghs Geert
Published: March 2017

In this review, we give a general overview of latent variable models. We introduce the general model and discuss various inferential approaches. Afterward, we present several commonly applied special cases, including mixture or latent class models, as well as mixed models. We apply many of these models to a single data set with simple structure, allowing for easy comparison of the results. This allows us to discuss advantages and disadvantages of the various approaches, but also to illustrate several problems inherently linked to models incorporating latent structures. Finally, we touch on model extensions and applications and highlight several issues often ignored when applying latent variable models.

Published: March 2017

Purpose: Aberrant activation of the intracellular tyrosine kinase Src has been implicated as a mechanism of acquired chemotherapy resistance in metastatic colorectal cancer (mCRC). Here, the oral tyrosine kinase Src inhibitor, dasatinib, was investigated in combination with FOLFOX and cetuximab.

Experimental Design: We performed a phase IB/II study of 77 patients with previously treated mCRC. Primary objectives were to determine the maximum tolerated dose, dose-limiting toxicities (DLT), pharmacodynamics, and efficacy. Using a 3 + 3 design, patients received FOLFOX6 with cetuximab and escalating doses of dasatinib (100, 150, 200 mg daily), followed by a 12-patient expansion cohort at 150 mg. Phase II studies evaluated FOLFOX plus dasatinib 100 mg in KRAS c12/13mut patients or in combination with cetuximab if KRAS c12/13WT. FAK and paxillin were utilized as surrogate blood biomarkers of Src inhibition, and paired biopsies of liver metastases were obtained in patients in the expansion cohort.

Results: In phase IB, the DLTs were grade 3/4 fatigue (20%) and neutropenia (23%). In phase II, grade 3/4 fatigue (23%) and pleural effusions (11%) were present. Response rates were 20% (6 of 30) in the phase IB escalation and expansion cohort and 13% (3 of 24) and 0% (0 of 23) in the KRAS c12/13WT and mutant cohorts of phase II, respectively. Median progression-free survival was 4.6, 2.3, and 2.3 months, respectively. There was no evidence of Src inhibition based on surrogate blood biomarkers or paired tumor biopsies.

Conclusions: The combination of dasatinib plus FOLFOX with or without cetuximab showed only modest clinical activity in refractory colorectal cancer. This appears to be primarily due to a failure to fully inhibit Src at the achievable doses of dasatinib. The combination of dasatinib plus FOLFOX with or without cetuximab did not show meaningful clinical activity in refractory colorectal cancer due to failure to fully inhibit Src.

Men's Views on Depression: A Systematic Review and Metasynthesis of Qualitative Research
Authors: Krumm Silvia , Checchia Carmen , Koesters Markus , Kilian Reinhold , Becker Thomas
Published: March 2017

Background: According to the concept of “male depression,” depression among men might be underdiagnosed and undertreated because of gender differences in symptoms and coping. There is evidence that men experience atypical depressive symptoms including irritability, aggression, substance abuse, and increased risk behavior. To date, a substantial number of qualitative studies on men's views on depression has been conducted in the last few decades. Methods: Based on a systematic review and metasynthesis of qualitative studies on men's subjective perspectives on depression, we aim at a comprehensive understanding of men's subjective views on depression with a specific focus on masculinity constructions. Results: Based on 34 studies assessed as appropriate for the study, 2 overarching subthemes could be identified: normative expectations regarding masculinity ideals and men's subjective perspectives of depression as “weakness.” Men's strategies include denial of “weakness” and “closing up.” Further themes include suicide, masculinity ideals as a healthy resource, and alternative masculinities. Discussion/Conclusions: Traditional masculinity values might serve as barriers but also as facilitators to adaptive coping strategies in depressed men. More research is needed to study the dimensions and role of alternative masculinities in the context of depression.
Postural Transitions during Activities of Daily Living Could Identify Frailty Status: Application of Wearable Technology to Identify Frailty during Unsupervised Condition
Authors: Parvaneh Saman , Mohler Jane , Toosizadeh Nima , Grewal Gurtej Singh , Najafi Bijan
Published: March 2017

Background: Impairment of physical function is a major indicator of frailty. Functional performance tests have been shown to be useful for identification of frailty in older adults. However, these tests are often not translatable into unsupervised and remote monitoring of frailty status at home and/or community settings. Objective: In this study, we explored daily postural transition quantified using a chest-worn wearable technology to identify frailty in community-dwelling older adults. Methods: Spontaneous daily physical activity was monitored over 24 h in 120 community-dwelling elderly (age: 78 ± 8 years) using an unobtrusive wearable sensor (PAMSys™, BioSensics LLC, Watertown, MA, USA). Participants were classified as non-frail and pre-frail/frail using Fried's criteria. A validated software package was used to identify body postures and postural transition between each independent postural activity such as sit-to-stand, stand-to-sit, stand-to-walk, and walk-to-stand. The transition from walking to sitting was further classified as quick sitting and cautious sitting based on presence/absence of a standing posture pause between sitting and walking. A general linear model univariate test was used for between-group comparison. Pearson's correlation was used to determine the association between sensor-derived parameters and age. Logistic regression model was used to identify independent predictors of frailty. Results: According to Fried's criteria, 63% of participants were pre-frail/frail. The total number of postural transitions, stand-to-walk, and walk-to-stand were, respectively, 25.2, 30.2, and 30.6% lower in the pre-frail/frail group when compared to the non-frail group (p < 0.05, Cohen's d = 0.73-0.79). Furthermore, the ratio of cautious sitting was significantly higher by 6.2% in pre-frail/frail compared to non-frail (p = 0.025, Cohen's d = 0.22). Total number of postural transitions and the ratio of cautious sitting also showed significant negative and positive correlations with age, respectively (r = -0.51 and 0.29, p < 0.05). After applying a logistic regression model, among tested parameters, walk-to-stand (odds ratio [OR] = 0.997 p = 0.013), quick sitting (OR = 1.036, p = 0.05), and age (OR = 1.073, p = 0.016) were recognized as independent variables to identify frailty status. Conclusions: This study demonstrated that daily number of specific postural transitions such as walk-to-stand and quick sitting could be used for monitoring frailty status by unsupervised monitoring of daily physical activity. Further study is warranted to explore whether tracking the daily number of specific postural transitions is also sensitive to track change in the status of frailty over time.

Published: March 2017

Background: Oxidative balance score (OBS) is a composite measure of oxidative stress-related exposures. The aim of this study was to investigate the association between OBS, end-stage renal disease (ESRD), and cardiovascular disease (CVD). Methods: Using data from the Chronic Renal Insufficiency Cohort, we calculated the main exposure OBS by summing up 12 apriori-defined pro- and antioxidant factors obtained from the diet history questionnaire and lifestyle assessment. We divided OBS into quartiles (Q1-Q4), with Q1 (predominance of pro-oxidants) as the reference. We analyzed OBS quartiles as an ordinal variable. Crude and adjusted hazards ratios (HRs) and 95% CIs were estimated using Cox proportional hazards models for time to ESRD and CVD. Results: Compared to Q1, Q4 (high antioxidant) was associated with ESRD in the crude model (HR 1.35, 95% CI 1.08-1.69) and adjusting for age, sex, and race (HR 1.36, 95% CI 1.09-1.71) but not in the fully adjusted model (HR 1.12, 95% CI 0.84-1.51). HR of ESRD increased as the OBS quartiles increased in the crude model (ptrend < 0.05) but not in the fully adjusted model (ptrend = 0.30). Compared to Q1, Q4 was associated with CVD in the crude (HR 1.33, 95% CI 1.06-1.68) but not adjusted models. The HR of CVD increased with an increase in OBS quartiles in the crude model (ptrend < 0.05). Conclusion: The reverse association between OBS and progression to ESRD suggests that perhaps the effect of oxidative balance-related exposure is different in the setting of established chronic kidney disease.
A EFETIVAÇÃO DO DIREITO À SAÚDE E SUA INTERFACE COM A JUSTIÇA SOCIAL
Authors: D’Ávila Luciana Souza , Saliba Graciane Rafisa
Published: March 2017

Pensar a saúde como direito de todos é uma tarefa complexa, dadas as desigualdades de acesso a condições dignas de vida. Nesse sentido, o objetivo deste trabalho é discutir a efetivação do direito à saúde tendo em vista sua centralidade na busca pela justiça social. Trata-se de uma reflexão subsidiada por uma extensa análise da literatura, a qual envolveu referências relacionadas ao direito à saúde e a diversos campos da doutrina jurídica (direitos humanos, direitos sociais, Direito Constitucional e Direito Econômico), tendo em vista sua relevância para o tema estudado. Verificou-se que, apesar dos avanços na efetivação dos direitos sociais no país, há ainda muito a se fazer – principalmente quando se pensa que, em tempos de crise econômica, os cortes orçamentários recaem diretamente sobre as políticas sociais, penalizando os cidadãos mais vulneráveis e em circunstâncias adversas. O direito à saúde está inteiramente interligado ao desenvolvimento das capacidades humanas e à qualidade de vida das pessoas e coletividades, sendo que o problema do descumprimento desse direito ultrapassa a implementação do Sistema Único de Saúde. Dessa forma, a efetivação do direito à saúde é um instrumento de justiça social, pois, além de possibilitar o exercício de outros direitos, exige o repensar de estruturas e comportamentos enraizados, levando ao estabelecimento de novas relações entre as instâncias de poder e promovendo a inclusão social.
A REGULAÇÃO DA PUBLICIDADE DE ALIMENTOS E BEBIDAS NÃO ALCOÓLICAS PARA CRIANÇAS NO BRASIL
Authors: Hartung Pedro Afonso Duarte , Karageorgiadis Ekaterine Valente
Published: March 2017

O presente artigo tem como objeto a compreensão da regulação da publicidade infantil de alimentos e bebidas não alcoólicas no Brasil. Entende-se que essa discussão deve ser contextualizada no âmbito mais abrangente do direcionamento de publicidade de qualquer produto, serviço ou marca ao público menor de 12 anos de idade, tendo em vista que a publicidade de alimentos e bebidas é uma espécie de prática comercial considerada abusiva e, portanto, ilegal pelas normas brasileiras e por recomendações de organismos internacionais. A publicidade, ao se dirigir diretamente à criança, utiliza-se de sua hipervulnerabilidade, em função de seu desenvolvimento inconcluso, para persuadi-la ao consumo, violando direitos assegurados pela legislação, como o direito ao respeito que compreende a inviolabilidade física, psíquica e moral. Especificamente, a publicidade infantil de produtos alimentícios e bebidas não alcoólicas com baixos valores nutricionais, além de se utilizar da vulnerabilidade infantil, impacta diretamente o aumento das taxas de obesidade e sobrepeso infantis, tornando-se, assim, um problema de saúde pública importante a ser regulado. No Brasil, a regulação dessa atividade comercial ocorre dentro do contexto amplo da restrição do direcionamento da comunicação mercadológica às crianças, a qual vem sendo discutida intensamente em diversos âmbitos do Estado, inclusive por meio de ações judiciais que geraram histórico precedente no Superior Tribunal de Justiça, considerando abusiva e ilegal tal prática.
O JULGAMENTO DO CASO DA FOSFOETANOLAMINA E A JURISPRUDÊNCIA DO SUPREMO TRIBUNAL FEDERAL
Authors: Zebulum José Carlos
Published: March 2017

Recentemente noticiou-se a difusão do uso da substância fosfoetanolamina sintética, conhecida como a pílula do câncer, entre portadores de neoplasia maligna. Ocorre que a substância, além de não contar com registro na Agência Nacional de Vigilância Sanitária, sequer havia concluído os estudos clínicos necessários à garantia de sua eficácia e segurança. Não obstante, o governo federal editou a Lei n. 13.269/2016, que autorizava o fornecimento pelo Sistema Único de Saúde sob determinadas condições, e diversas liminares foram concedidas obrigando o Estado a fornecê-la. A questão foi apreciada pelo Supremo Tribunal Federal em dois rumorosos julgamentos, em que a Corte suspendeu todas as liminares concedidas e suspendeu a eficácia da referida lei por indícios de inconstitucionalidade. Neste artigo analisamos os fundamentos das citadas decisões no contexto de posicionamentos anteriores da Corte e das orientações estabelecidas no julgamento do Agravo Regimental na Suspensão de Tutela Antecipada 175.

Published: March 2017

A new species, Brownlowia latifiana (Malvaceae-Brownlowioideae), endemic to Terengganu, Peninsular Malaysia, is described and illustrated. This new species has most of its morphological characters that are related to those of the genus Jarandersonia. Therefore, a standard morphological taxonomic revision and morphometric analysis were carried out to assess the status of Brownlowia latifiana. Results of the morphometric analysis based on morphological characters showed that Brownlowia latifiana is embedded within the clades of Brownlowia but distanced from the clades Jarandersonia. Brownlowia formed a distinct clade in the clustering tree well separated from the Jarandersonia. A distribution map and a conservation assessment using the IUCN Red List categories and criteria are provided.

Published: March 2017

Acer ningmingensis Y.F.Chen & W.O.Wong sp.nov. is described for asymmetric samaras from the Oligocene Ningming Formation in Guangxi Zhuang Autonomous Region, South China. It represents the Oligocene Acer occurrence in the lowest latitude and the only record from a tropical zone today. Together with the coeval fossil record from the mid-latitudes in China, Korea and Japan, the present discovery suggests that the genus Acer had been widely distributed in East Asia by the Oligocene, during which the climate in the Ningming area was cooler than the present.

Two species of the genus Cladotanytarsus Kieffer, 1921 are described as adult males, both peculiar in having distinctively elongated hypopygial anal points. The male of Cladotanytarsus bilyji Giłka et Puchalski, sp. nov. (Canada, Manitoba; USA, Ohio) is presumed to be a close relative of C. nigrovittatus (Goetghebuer, 1922). Another unknown Cladotanytarsus species (USA, Illinois and Louisiana) keys with the European C. donmcbeani Langton et McBean, 2010. The intraspecific variability of the male C. acornutus Jacobsen et Bilyj, 2007 is also presented on the basis of new records (Canada, Ontario; USA, South Carolina). Cladotanytarsus males with similarly structured elongate anal points are reviewed, including C. tobaquardecimus Kikuchi et Sasa, 1990, considered a junior synonym (syn. nov.) of C. conversus (Johannsen, 1932). As a compilation of this study, a key to the identification of the adult males of 14 Cladotanytarsus species is provided.

Published: March 2017

We evaluated the performance of laser ablation analysis techniques such as laser-induced breakdown spectroscopy (LIBS), laser ablation inductively coupled optical emission spectrometry (LA-ICP-OES), and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), in comparison with that of ICP-OES using aqueous solutions for the quantification of sulfur (S) in edible salts from different geographical origins. We found that the laser ablation based sampling techniques were not influenced by loss of S, which was observed in ICP-OES with aqueous solutions for a certain salt upon their dissolution in aqueous solutions, originating from the formation of volatile species and precipitates upon their dilution in water. Although detection of S using direct laser sampling with LA-ICP-MS has well-known isobaric and polyatomic interferences, LIBS and LA-ICP-OES showed good accuracy in the detection of S for all salts. LIBS also provided the ability to identify the dominant chemical form in which S is present in salts. Correlation between S and oxygen, observed in LIBS spectra, provided chemical information about the presence of S2– or [Formula: see text], which are associated with the origin and quality of edible salts.
Simulation of air bubble’s creation, compression, and transport phenomena in resin transfer moulding
Authors: Aaboud Bouchra , Saouab Abdelghani , Nawab Yasir
Published: March 2017

The presence of air bubbles impacts the quality of the produced composite part, by reducing its mechanical properties, and also it might degrade its surface finish. The modelling of air bubbles entrapment requires the consideration of three phenomena: air bubble’s creation, compression and transport. Very few studies have been conducted on this latter phenomenon. The model developed in this work is proposed for a unidirectional reinforcement. It is integrated into a simulation code of resin transfer moulding process, via the control volume finite element method. That model takes into account the dual scale pores in fibrous media, and simulates the three said phenomena highlighting the migration phenomenon and the coexistence of micro and macro air bubbles. As a result, the spatial distribution of created, compressed and transported air bubbles as well as its macro and micro remaining quantities, in the end of the injection are estimated.

Does Tourist–Host Social Contact Reduce Perceived Cultural Distance?
Authors: Fan Daisy X.F. , Zhang Hanqin Qiu , Jenkins Carson L. , Lin Pearl M.C.
Published: March 2017

Tourist–host social contact significantly influences the perceptions of tourists and deserves more attention from scholars in the field of tourism research. However, studies on the relationship between these two constructs are limited. To address this research gap, the present study develops and validates instruments for measuring social contact and perceived cultural distance in the context of tourism, explores the effects of social contact on perceived cultural distance, and provides implications for tourism stakeholders, including governments, tourism operators, and local communities. A survey was conducted among Hong Kong tourists traveling to Mainland China. The study had two significant findings: (1) the quality of contact negatively influences tourists’ perceived cultural distance and (2) in terms of the quantity of contact, social-oriented contacts negatively influence perceived cultural distance, whereas service-oriented contacts positively affect perceived cultural distance. Implications were provided to contribute to theoretical and empirical realms, and to guide policy formulation.

Published: March 2017

Objective

Veterans of war affected by posttraumatic stress disorder (PTSD) are at increased risk for cardiovascular diseases. We aimed to compare brachial and central blood pressures between veterans with PTSD and controls.

Method

In this case-control study on veterans of Iran–Iraq war, 50 veterans with PTSD and 50 veterans as controls were selected from an outpatient clinic and matched for age ±3 years. Exclusion criteria were malignancies, severe anatomical defects such as amputated extremities, history of PTSD before serving in war, comorbid psychiatric disorders other than anxiety or depressive disorders. Detailed history was taken concerning medical and social aspects. Beck Depression Inventory was used for depressive symptoms. Brachial blood pressures were measured using both auscultatory and oscillometric devices. Measures of central hemodynamics were estimated accordingly. Data on lipid profile were collected either through medical records or newly required lab tests.

Results

Brachial systolic, diastolic, and pulse pressures as well as estimated central systolic and diastolic pressures were significantly higher in the PTSD group. Beck Depression Inventory scores, frequency of diabetes mellitus, and hypertension were significantly higher in the PTSD group. PTSD status was an independent predictor of both brachial and central systolic and diastolic pressures.

Conclusions

We demonstrated increased measures of blood pressure in veterans with PTSD independent of depression and other risk factors. Further research is warranted to confirm our results.

Published: March 2017

Waterpipe smoking among youth and adolescents in Iran has gained in popularity. The aim of this study was to investigate the relationship between waterpipe smoking and different dimensions of religiosity in a sample of students attending two major universities in South East Iran. A total of 682 students completed a waterpipe and cigarette smoking questionnaire along with the Duke University Religion Index. The lifetime prevalence of dual cigarette and waterpipe use was 48.3%, with prevalence of current use (within the last 30 days) of 24.9%. The proportions of lifetime and current waterpipe-only users were 27.0% and 18.8%, respectively. Students who participated more often in private religious activities were less likely to report engaging in waterpipe smoking (odds ratio: 0.82; 95% confidence interval: 0.71–0.98). A higher level of attendance of religious services was negatively associated with dual cigarette and waterpipe smoking (odds ratio: 0.71; 95% confidence interval: 0.54–0.93). Waterpipe-only use was significantly higher among males, students who had lower grade point averages, those who reported having a close friend or a family member who was a waterpipe smoker. To conclude, it is possible that religious observance may have a protective role in lowering waterpipe usage among Iranian university students.

Background

The ability to accurately assess tumor size in ductal carcinoma in situ (DCIS) is an important clinical issue when selecting the appropriate treatment plan.

Purpose

To compare the accuracy of using mammography, ultrasound (US), and magnetic resonance imaging (MRI) to assess DCIS tumor size based on imaging and histopathological findings.

Material and Methods

Fifty-six patients with DCIS were included. Mammography, US, and MRI were reviewed, and the accuracy of the measured tumor sizes were compared with the imaging and histopathological parameters.

Results

If visible, tumor measurements demonstrated high reliability with the pathologically determined size, with the best results obtained using US ( k = 0.851) followed by mammography ( k = 0.815) and MRI ( k = 0.738). Tumor size assessment was significantly more accurate when the lesion was shown as a mass on US ( P = 0.003) or MRI ( P < 0.001) with minimal and mild background parenchymal enhancement ( P = 0.016) on MRI. When mammography was used to assess tumor size, the tumors with positive estrogen receptor status and luminal A subtype demonstrated a significantly more accurate tumor size.

Conclusion

The combination of US and MRI, in addition to mammography, has an important role in assessing the exact tumor extent of DCIS.
Artificial neural network for correction of effects of plasticity in equibiaxial residual stress profiles measured by hole drilling

Published: March 2017

The hole drilling method is a widely known technique for the determination of non-uniform residual stresses in metallic structures by measuring strain relaxations at the material surface caused through the stress redistribution during drilling of the hole. The integral method is a popular procedure for solving the inverse problem of determining the residual stresses from the measured surface strain. It assumes that the residual stress can be approximated by step-wise constant values, and the material behaves elastically so that the superposition principle can be applied. Required calibration data are obtained from finite element simulations, assuming linear elastic material behavior. That limits the method to the measurement of residual stresses well below the yield strength. There is a lack of research regarding effects caused by residual stresses approaching the yield strength and high through-thickness stress gradients as well as the correction of the resulting errors. However, such high residual stresses are often introduced in various materials by processes such as laser shock peening, for example, to obtain life extension of safety relevant components. The aim of this work is to investigate the limitations of the hole drilling method related to the effects of plasticity and to develop an applicable and efficient method for stress correction, capable of covering a wide range of stress levels. For this reason, an axisymmetric model was used for simulating the hole drilling process in ABAQUS involving plasticity. Afterward, the integral method was applied to the relaxation strain data for determining the equibiaxial stress field. An artificial neural network has been used for solving the inverse problem of stress profile correction. Finally, AA2024-T3 specimens were laser peened and the measured stress fields were corrected by means of the trained network. To quantify the stress overestimation in the hole drilling measurement, an error evaluation has been conducted.

Adverse interactions between police and the public hurt police legitimacy, cause harm to both officers and the public, and result in costly litigation. Early intervention systems (EISs) that flag officers considered most likely to be involved in one of these adverse events are an important tool for police supervision and for targeting interventions such as counseling or training. However, the EISs that exist are not data-driven and based on supervisor intuition. We have developed a data-driven EIS that uses a diverse set of data sources from the Charlotte-Mecklenburg Police Department and machine learning techniques to more accurately predict the officers who will have an adverse event. Our approach is able to significantly improve accuracy compared with their existing EIS: Preliminary results indicate a 20% reduction in false positives and a 75% increase in true positives.
Religiosity and Health Through the Decades: Is There a Gender Difference?
Authors: Mukerjee Swati , Venugopal Arun
Published: March 2017

Purpose:

An empirical examination of the long-term association, disaggregated by gender, between religiosity and self-rated health with reference to demographic shifts in labor force participation, education, and income.

Design:

General Social Survey data.

Setting:

United States, 1974 to 2012.

Participants:

A total of 23 353 respondents.

Measures:

Self-assessed health; 2 key religiosity variables: attendance and intensity of belief; income, labor market variables, education, standard demographic variables, household size, region, and time dummies.

Analysis:

Probit estimation conducted for the aggregate sample by gender as well as by decades to examine possible gender differential changes over time.

Results:

Attendance has declined overall with a much greater decline for women. The overall positive association between religiosity and health masks considerable heterogeneity across gender and time; higher and stable for males, there is no longer a significant association for females. Increased education, income, and labor force participation can explain only part of this association. Education is the strongest mediator.

Conclusion:

The way women and men benefit from religious attendance has changed, suggesting that some pathways may be working differently for women now, especially those with less education. Moving away from church networks could be due to a perceived lack of support or substitution by other social networks. Ceteris paribus, since religious participation has been shown to weaken preference for risky consumption, declining participation, especially for women, may show up as an increase in risky behavior.
Relationship of Proactive Personality With Life Satisfaction During Late Career and Early Retirement
Authors: Maurer Todd J. , Chapman Elizabeth F.
Published: March 2017

This investigation of proactive personality focused on life satisfaction during a 10-year period in which people went from being full-time employees to being fully retired. The study contributes at the intersection of the literatures on proactive personality, careers, retirement, and life satisfaction. In a sample of 118 recent retirees across the U.S. workforce (mean age = 65), personality was correlated with assessments of life satisfaction over the prior 10-year period and a variety of control variables (individual, household, and previous job) were included so that we could examine the incremental and unique effects of proactive personality. Proactive people were more satisfied during this critical period of life. This was true whether differences in life satisfaction included or excluded differences in career satisfaction during that time. We discuss future research implications and potential practical implications for enhancing satisfaction during a life stage in which proactive behavior may be beneficial.

Published: March 2017

The driving device of the main steam and feed water isolation valves is one of the most important electromechanical equipment in nuclear power plants, and its motion performances are related to the safety of nuclear power plants. This article proposes an optimization methodology to research the motion performances. In the methodology, inputs are the motion performance indexes and the major influencing parameters with no need for complex mathematical models of the electromechanical equipment; the co-simulation model or the prototype are adopted to illustrate the influence rules of major parameters on the motion performance indexes; objective functions for optimization, which combine motion performances with weight factors, can reveal the influence rule curves. Then based on the methodology, motion performances of the equipment are analyzed and the key indexes are selected. Besides, the maximum pressure of the driving device is chosen as the major parameter and a dimensionless objective function synthesizing the motion performance indexes is proposed. Finally, the influence rule curve where the dimensionless function varies with the maximum pressure is obtained by the co-simulation and the experimental study on the prototype verifies the results, which provides references for the further research and development in the engineering application. For other electromechanical equipment, the method is an efficient tool to design, verify, and optimize the performances.
Intravenous immunoglobulin: a biological corticosteroid-sparing agent in some autoimmune conditions
Authors: Watad A , Amital H , Shoenfeld Y
Published: March 2017

Intravenous immunoglobulin (IVIg) is increasingly used for the treatment of autoimmune and systemic inflammatory diseases. This compound is effective in a wide range of clinical conditions other than primary immunodeficiency, including autoimmune diseases, inflammatory disorders, infections, organ transplantation, and possibly supportive therapy for cancer. Systemic corticosteroids remain the gold standard treatment for many autoimmune diseases, but their long-term use is associated with complications in diverse organs and systems. Osteoporosis, osteonecrosis, cardiovascular disease, infections, and cancer have been associated with this treatment. Therefore, physicians are occasionally forced to withdraw the treatment with steroids. Biological agents may represent a good alternative, but in addition to being very expensive, these agents may have serious side effects. This review aimed to cover the major advances in the use of IVIg as a steroid-sparing agent in some relevant autoimmune diseases.

Published: March 2017

Introduction: Health disparities persist among African Americans (AAs) and Latino adults with type 2 diabetes. The purpose of this research was to use PhotoVoice to examine AAs and Latinos’ daily experiences of managing diabetes. Method: An exploratory, descriptive study using PhotoVoice and focus groups was conducted over a 3-week period: Week 1 orientation session, Week 2 photo taking and returning cameras, and Week 3 focus group to share and discuss photos. Results: Ten AAs and nine Latino adults were enrolled, forming four focus groups. Four categories emerged: (1) daily life living with type 2 diabetes mellitus, (2) negative and positive emotions, (3) supports and barriers, and (4) needs. The social determinants of health influencing diabetes self-care were observed in discussions and photos—this included the built environment to promote a healthy lifestyle, social support, and education. Implications: PhotoVoice promotes culturally congruent care to better understand AA and Latinos’ experience living with type 2 diabetes mellitus.
