Towards soliton solutions of a perturbed sine-Gordon equation

We give arguments for the existence of exact travelling-wave solutions, of old (in particular solitonic) and new type, of a perturbed sine-Gordon equation on the real line or on the circle, and classify them. The perturbation of the equation consists of a constant forcing term and a linear dissipative term. Such solutions are allowed exactly by the energy balance of these terms, and can be observed experimentally e.g. in the Josephson effect in the theory of superconductors, which is one of the physical phenomena described by the equation.
Reviews of bearing vibration measurement using fast Fourier transform and enhanced fast Fourier transform algorithms

The rolling element bearing is one of the most critical components in a machine. Vibration signals resulting from these bearings imply important bearing defect information related to the machinery faults. Any defect in a bearing may cause a certain vibration with specific frequencies and amplitudes depending on the nature of the defect. Therefore, the vibration analysis plays a key role for fault detection, diagnosis, and prognosis to reach the reliability of the machines. Although fast Fourier transform for time–frequency analysis is still widely used in industry, it cannot extract enough frequencies without enough samples. If the real frequency does not match fast Fourier transform frequency grid exactly, the spectrum is spreading mostly among neighboring frequency bins. To resolve this drawback, the recent proposed enhanced fast Fourier transform algorithm was reported to improve this situation. This article reviews and compares both fast Fourier transform and enhanced fast Fourier transform for vibration signal analysis in both simulation and practical work. The comparative results verify that the enhanced fast Fourier transform can provide a better solution than traditional fast Fourier transform.

ScholarWorks @ UTRGV ScholarWorks @ UTRGV Depression in Mexican Americans with Diagnosed and Depression in Mexican Americans with Diagnosed and Undiagnosed Diabetes Undiagnosed Diabetes

Objective— Depression and diabetes commonly co-occur, however the strength of the physiological effects of diabetes as mediating factors towards depression is uncertain. Methods— We analyzed extensive clinical, epidemiological and laboratory data from (n=2081) Mexican Americans aged 35 to 64 years divided into three groups: Diagnosed (self-reported) diabetes (n =335), Undiagnosed diabetes (n=227) and No diabetes (n=1519) who did not meet criteria for diabetes. Undiagnosed diabetes participants denied being diagnosed with diabetes, but on testing met the 2010 American Diabetes Association and World Health Organization definitions of diabetes. Depression was measured using the Center for Epidemiological Studies-Depression (CES-D) scale. Weighted data were analyzed using dimensional and categorical outcomes using univariate and multivariate models. Results— The Diagnosed diabetes group had significantly higher CES-D scores than both the No diabetes and Undiagnosed diabetes (p≤ 0.001) groups, whereas the No diabetes and Undiagnosed diabetes groups did not significantly differ from each other. The Diagnosed diabetes subjects were more likely to meet the CES-D cut-off score for depression compared to both the No diabetes and Undiagnosed diabetes groups (p = 0.001) respectively. The Undiagnosed diabetes group was also less likely to meet the cut-off score for depression than the No diabetes group (p =0.003). Our main findings remained significant in models that controlled for socio-demographic and clinical confounders. Conclusions— Meeting clinical criteria for diabetes was not sufficient for increased depressive symptoms. Our findings suggest that the “knowing that one is ill” is associated with depressive symptoms in diabetic subjects.
Structural properties of singularities of semiconcave functions

A semiconcave function on an open domain of R" is a function that can be locally represented as the sum of a concave function plus a smooth one. The local structure of the singular set (non-differentiability points) of such a function is studied in this paper. A new technique is presented to detect singularities that propagate along Lipschitz arcs and, more generally, along sets of higher dimension. This approach is then used to analyze the singular set of the distance function from a closed subset of R^n
COPD_A_280157 351..365

1Respiratory Research Department, University Hospitals Birmingham NHS Foundation Trust, Birmingham, UK; 2Institute of Inflammation and Ageing, University of Birmingham, Birmingham, B15 2TT, UK; 3Institute for Applied Health Research, University of Birmingham, Birmingham, B15 2TT, UK Abstract: The response to treatment and progression of Chronic Obstructive Pulmonary Disease (COPD) varies significantly. Small airways disease (SAD) is being increasingly recognized as a key pathological feature of COPD. Studies have brought forward pathological evidence of small airway damage preceding the development of emphysema and the detection of obstruction using traditional spirometry. In recent years, there has been a renewed interest in the early detection of SAD and this has brought along an increased demand for physiological tests able to identify and quantify SAD. Early detection of SAD allows early targeted therapy and this suggests the potential for altering the course of disease. The aim of this article is to review the evidence available on the physiological testing of small airways. The first half will focus on the role of lung function tests such as maximum mid-expiratory flow, impulse oscillometry and lung clearance index in detecting and quantifying SAD. The role of Computed Tomography (CT) as a radiological biomarker will be discussed as well as the potential of recent CT analysis software to differentiate normal aging of the lungs to pathology. The evidence behind SAD biomarkers sourced from blood as well as biomarkers sourced from sputum and broncho-alveolar lavage (BAL) will be reviewed. This paper focuses on CC-16, sRAGE, PAI-1, MMP-9 and MMP-12.
E XERCISE I NTENSITY AND T ECHNICAL D EMANDS OF S MALL -S IDED S OCCER G AMES FOR U NDER -12 AND U NDER -14 P LAYERS : E FFECT OF A REA PER P LAYER

P, and S. Exercise intensity and technical demands of small-sided soccer games for under-12 and under-14 players: Effect of area per player. J Strength Cond Res 31(6): 1486–1492, 2017—The aim of this study was to evaluate the effects of 6 different areas per player (A P ) on exercise intensity (EI) measured during small-sided games (SSGs) and expressed as percentage of maximal heart rate (%MHR) and technical actions (TAs) involvement with the ball, crosses, headers, tackles, shots on goal, dribbling, passing, and target passing-in U-12 and U-14 soccer players during SSGs. Seventeen male U-12 soccer players (age 10.0 6 0.5 years, body mass 39.3 6 5.3 kg, and height 143.8 6 4.6 cm) and 16 male U-14 soccer players (age 13.2 6 0.3 years, body mass 46.6 6 11.9 kg, and height 154.8 6 8.5 cm) performed SSGs with different A P : 40, 50, 66.7, 90, 112.5, and 150 m 2 . Our results indicate that at larger A P , the U-12 group’s mean EI values were signiﬁcantly higher than those at smaller A P ( p # 0.05); in addition, intergroup comparison showed that EI was higher in U-12 than that in U-14 players when A P of 112.5 and 150 m 2 were considered ( p # 0.05). Technical action analysis evidenced that moving from smaller to larger A P , U-14 players adapted better to A P changes. In conclusion, these results suggest that A P inﬂuences differently EI and TAs in U-12 and U-14 players. Our results could be taken into account by conditioning coaches to better tailor the physiological and technical training in young players through the mod-ulation of A P .
The role of macroeconomic, policy, and forecaster uncertainty in forecast dispersion

We explore the role of uncertainty in explaining dispersion in professional forecasters’ density forecasts of real output growth and inflation. We consider three separate notions of uncertainty: general macroeconomic uncertainty (the fact that macroeconomic variables are easier to forecast at some times than at others), policy uncertainty, and forecaster uncertainty. We find that dispersion in individual density forecasts is related to overall macroeconomic uncertainty and policy uncertainty, while forecaster uncertainty (which we define as the average in the uncertainty expressed by individual forecasters) appears to have little role in forecast dispersion.
KRYLOV CONVERGENCE ACCELERATION AND DOMAIN DECOMPOSITION METHODS FOR NONMATCHING GRIDS

The numerical solution of partial differential equations is an important research topic in the field of scientific computing and numerical simulation. After discretisation, very large systems of linear equations have to be solved. In domain decomposition methods, the domain is split into a number of subdomains and the resulting subproblems are coupled via “artificial” boundary conditions. Krylov subspace methods are iterative methods to solve systems of linear algebraic equations. They are easy to implement but require a good preconditioner. In this thesis we develop efficient numerical solvers for partial differential equations, based on the combination of Krylov subspace methods, such as Flexible GMRES, with domain decomposition preconditioning and to extend the applicability of the developed technique to (overlapping) nonmatching grids. The first part of the thesis deals with improving the convergence of the iterative solver. The domain decomposition method can be optimised by determining an optimal coupling between the subdomains. This is done by imposing boundary conditions for the subdomain problems. Ritz and Harmonic Ritz values and the corresponding vectors are studied to understand the convergence behaviour of GMRES and to extract important information about the eigenvalue spectrum of the preconditioned matrix. With the Ritz vectors corresponding to outlying eigenvalues we can speed up the solution process. This has been successfully applied in a solver for the Shallow Water Equations. We also constructed an optimised nested Krylov method. This is an attractive way to extract a near-optimal approximation
A Time of Challenge and Growth: A Qualitative Study of Newly Qualified Nurses’ Experience

Background: In any country the transition from student to Registered Nurse is a rewarding but challenging and stressful time. Nurses terminating employment within one year of qualification have been reported as 58% in Taiwan. Therefore, the experience of NQNs’ transition from the role of student to qualified nurse after being employed in their first posts in their nursing careers in Taiwan is worthy of research. Purpose: To explore experiences of newly qualified nurses (NQNs) during the first twelve months of their career in Taiwan. Methods: A primarily cross-sectional qualitative research design was used. These were a purposive sample of 28 NQNs during the first 12 months as Registered Nurses. Semi-structured interviews were undertaken with groups of participants. Data analysis was undertaken within the Thematic Content Analysis Framework. Results: Four main themes of newly qualified nurses’ experiences were identified: Perceptions of becoming a nurse; Reality challenge; Developing competence; and Interpersonal relationships. Conclusion: NQN’s experiences in clinical practice during the first twelve months employment sound very like a reality challenge. Successful transition was influenced by personal, social and environmental work factors. NQNs identified that their new role was based on what they evaluated as limited knowledge and skills. They addressed the importance of interpersonal relationship influenced their transition experiences. The findings have implications for education of student nurses and their support during transition to the role of qualified nurses. This requires a coordinated response from nursing schools, hospitals and government to increase those who adapt to their new roles and develop successful nursing careers.
Clinical and Economic Bene ﬁ ts Associated With the Achievement of Both HbA 1c and LDL Cholesterol Goals in Veterans With Type 2 Diabetes Mellitus

OBJECTIVE d This study compared the clinical and economic bene ﬁ ts associated with dual-goal achievement, glycated hemoglobin (HbA 1c ) , 7% (53 mmol/mol) and LDL cholesterol (LDL-C) , 100 mg/dL, with achievement of only the LDL-C goal or only the HbA 1c goal in veterans with type 2 diabetes mellitus (T2DM). RESEARCH DESIGN AND METHODS d This retrospective cohort analysis evaluated electronic medical records (Veterans Integrated Service Network 16) in adult T2DM patients with two or more measurements of LDL-C and HbA 1c between 1 January 2004 and 30 June 2010 ( N = 75,646). Cox proportional hazards models were used to compare microvascular and car- diovascular outcomes by goal achievement status; generalized linear regression models were used to assess diabetes-related resource utilization (hospitalization days and number of outpa- tient visits) and medical service costs. RESULTS d Relative to achievement of only the LDL-C goal, dual-goal achievement was associated with lower risk of microvascular complications (adjusted hazard ratio [aHR] 0.79), acute coronary syndrome (0.88), percutaneous coronary intervention (0.78), and coronary artery bypass graft (CABG) (0.74); it was also associated with fewer hospitalization days (adjusted incidence rate ratio [aIRR] 0.93) and outpatient visits (0.88), as well as lower diabetes-related annual medical costs ( 2 $130.89). Compared with achievement of only the HbA 1c goal, dual- goal achievement was associated with lower risk of the composite cardiovascular-related end point (aHR 0.87) and CABG (aHR 0.62),
Sports Concussion: A Clinical Overview Sports Concussion: A Clinical Overview

Concussion is an injury risk associated with participation in collision sports. It has been identified as a research priority for many contacts and collision sports governing bodies worldwide. However, concussion remains under-researched in terms of clinical transla- tion from both experimental models to clinical understanding, and from clinical studies to sports policy. Currently, the clinical management of concussion is largely guided by the presence or absence of symptoms with recovery indicated once all post-injury symptoms have resolved. Management of concussion includes physical and cognitive rest until acute symptoms resolve, with a graded program of exertion implemented prior to medical clearance and return-to-play. Considering the potential sequelae, the heterogeneity of symptoms, and the lack of an intervention known to prevent concussion, it is not any wonder that concussion is one of the most complex and perplexing injuries faced by medical professionals, and why making the return-to-play decision can be quite challenging. This chapter will provide an overview of the current clinical management guidelines and research literature pertaining to identification and diagnosis of injury, acute and post-acute management, and return-to-play decision-making. The traditional standard assessment process (e.g., symptom reporting, cognitive assessment, balance testing), new methods and advanced technology (e.g., ocular-motor test- ing, neuroimaging techniques), and biomarkers (e.g., blood plasma and serum, fluid) have led to greater insights into sports concussion and will also be briefly explored in this chapter. to diagnose, assess, and manage for the sports medicine professional. The acute effects, but also the potential long-term issues, need considered when through a return-to-activity. A comprehensive clinical assessment of involves a multimodal but each tool and how For some measures a pre-injury, post-injury paradigm is appropriate for interpreting the results, but for others post-injury performances can be interpreted with the use of normative data. A conservative approach to the return-to-play is recommended, and the final return-to-activity decision should be made by a medical professional.
Dietary ascorbic acid requirement for the optimum growth performances and normal skeletal development in juvenile hybrid grouper, Epinephelus fuscoguttatus (cid:1) Epinephelus lanceolatus Journal of King Saud University – Science

A 10-week feeding trial was conducted to determine the dietary ascorbic acid required by the juvenile hybrid grouper, Epinephelus fuscoguttatus (cid:1) Epinephelus lanceolatus for its optimum growth, survival, and normal skeletal development. Eight experimental diets containing graded levels of ascorbic acid (4.8, 11.2, 24.1, 47.2, 75.6, 95.4, 156.2, and 303.0 mg/kg) were prepared and labeled as C5, C11, C24, C47, C76, C95, C156 and C303, respectively. Each diet was fed to triplicate groups of ﬁsh [initial weight 7.71 ± 0.06 g (mean ± SD)]. The ﬁsh were cultured in 150 L of ﬁber glass tank supplied with aeration and ﬂow-through seawater system (3 L min (cid:3) 1 ) with the stocking density of 15 individual per tank. During the feeding trial, ﬁsh were hand-fed with the experimental diets to apparent satiation twice a day (8:00 and 15:00). Bulk weight of each ﬁsh group was measured at 2 weeks interval. At the end of the experiment, ﬁsh were sacriﬁced and subjected to radiographic imaging to detect the presence of skeletal deformities. The body weight gain (BWG) of ﬁsh was in the range from 628.51 ± 39.61 to 880.18 ± 113.30%. Fish fed with the C156 diet gained the highest BWG and speciﬁc growth rate (SGR). In the present study, ascorbic acid level did not affect the survival of the hybrid grouper. The feed conversion ratio (FCR) value in all dietary treatments appeared to be less than 1, indicating hybrid grouper have high efﬁciency of convert-ing feed into body mass. Multiple types of skeletal deformities (fusion, kyphosis, lordosis, and scoliosis) were observed in the ﬁsh fed with the diets containing less than 95 mg/kg of ascorbic acid. In conclusion, dietary ascorbic acid levels can affect the growth performance and normal skeletal development in the hybrid grouper. Although 95 mg/kg was sufﬁcient for normal skeletal development, 156 mg/kg of dietary ascorbic acid is recommended for feed development to maintain the optimum growth and normal skele- tal development in the ﬁsh.

This study sought to identify maternal factors and family dynamics that affect HPV vaccination behavior. Participants and Methods: Participants were recruited at an OB/GYN clinic in Linares, Chile. Participation was voluntary, and eligibility required 1) having an adolescent daughter between 9 and19 years-old and 2) demonstrating a willingness to discuss HPV-related topics. Thirty semi-structured interviews were conducted to generate qualitative data analyzed using Grounded Theory methodology. Results: Three thematic constructs emerged from the interviews. Mothers’ motivations to vaccinate centered on disease prevention and trust in the medical system but were influenced by notions of sexual liberalism and promiscuity. Second, participants desired, but often had trouble finding, adequate information about vaccine safety and turned to the internet. Third, joint decision making in the family about vaccination led to open family discussions about sex and sexuality. Conclusion: Chile’s school-based opt-out HPV vaccination program engenders a unique landscape of maternal decision-making, risk-benefit analysis, information-seeking, and athome discussion. More studies are needed around the variable role of fathers in the decisionmaking process.
Genetic and Antigenic Diversities of Major Immunoreactive Proteins in Globally Distributed Ehrlichia canis Strains (cid:1)

The extent of knowledge regarding the diversity of globally distributed Ehrlichia canis strains has been limited to information gained from a few evolutionarily conserved genes. In this study, E. canis strains from the United States (strain Jake [US]), Brazil (strain Sa˜o Paulo [BR]), and Israel (strain 611 [IS] and Ranana [IS-R]) were used to examine the antigenic and genetic diversities of four well-characterized major immunoreactive protein genes/proteins. gp36 and gp200 were the most divergent genes, and nucleotide substitutions in the gp36 tandem repeat region of the IS strain, but not the IS-R strain, resulted in two amino acid differences (S 3 P and P 3 T) in each nine-amino-acid repeat (epitope-containing region). DNA sequences of gp19 and gp140 were completely conserved in the US and BR strains, but differences were found in the Israeli strains, including two fewer tandem repeats in gp140 and a single amino acid substitution in gp19 from the IS strain. E. canis whole-cell lysates from each isolate were examined by Western immunoblotting using sera from naturally infected dogs from each country, and four major immunoreactive proteins (gp19, gp36, gp140, and gp200) were identiﬁed in each strain using protein-speciﬁc antisera. The US and BR strains exhibited highly conserved immunoreactive protein proﬁles, while some differences were identiﬁed in the IS strain. Sera from naturally infected Israeli dogs conﬁrmed gene sequencing information, which demonstrated two distinct E. canis strains, deﬁned by the gp36 gene. Conversely, gp19 was strongly reactive and present in all E. canis isolates. gp140 and gp200 were also present in all strains, although gp140 in the IS strain had two fewer tandem repeats and exhibited a smaller mass.
