Multiple Levels of Influence on Lifestyle Behaviors among Cancer Survivors in Racial and Ethnic Minority Groups: A Systematic Review

Objective. This systematic review aimed to provide a critical summary of studies of physical activity (PA) and diet among racial/ethnic minority cancer survivors. Guided by the socio-ecological model, we identified factors across multiple levels—individual, family/social support, provider/team, and organization/local community/policy environment—that affect PA and diet among racial/ethnic minority survivors. Methods. We searched the Ovid MEDLINE, EBSCO CINAHL, Ovid PsycInfo, and PubMed databases. We extracted the behavior of focus (i.e., PA and diet), cancer type, race/ethnicity, and the level(s) of influence (and the corresponding factor(s)), and each eligible study investigated individual (e.g., demographic characteristics, psychological factors), family/social support, provider/team (e.g., healthcare provider recommendations), and organization/local community/policy environment (e.g., neighborhood/social environment). Results. Of 1,603 studies identified, 23 unique studies were eligible. Most studies included breast cancer survivors (n = 19) and Black survivors (n = 13). Seventeen studies assessed associations between PA and factors at the level of the individual (16 studies), family/social support (two studies), provider/team (one study), or organization/local community/policy environment (four studies). Eleven studies assessed associations between diet and factors at the level of the individual (11 studies), family/social support (two studies), provider/team (one study), or organization/local community/policy environment (two studies). Only five studies simultaneously investigated factors across multiple levels. Most demographic and cancer-related factors were not associated with PA or diet. Overall, factors from social-cognitive theories (e.g., self-efficacy) were positively associated with PA. Less consensus was found regarding diet because fewer studies existed, and they also investigated a diverse range of eating behaviors. Conclusions. There is a critical need for studies of PA and diet that investigate multiple levels of influence particularly for Asian American survivors, male survivors, and cancers other than breast cancer. Social-cognitive theories may help guide the designing of multilevel PA interventions for racial/ethnic minority survivors. Studies assessing overall eating quality or adherence to dietary guidelines are needed.

Magnetic Flux Leakage (MFL) based Defect Characterization of Steam Generator Tubes using Artificial Neural Networks

Material defects in the Steam Generator Tubes (SGT) of sodium cooled fast breeder reactor (PFBR) can lead to leakage of water into sodium. The water and sodium reaction will lead to major accidents. Therefore, the examination of steam generator tubes for the early detection of defects is an important requirement for safety and economic considerations. In this work, the Magnetic Flux Leakage (MFL) based Non Destructive Testing (NDT) technique is used to perform the defect detection process. The rectangular notch defects on the outer surface of steam generator tubes are modeled using COMSOL multiphysics 4.3a software. The obtained MFL images are de-noised to improve the integrity of flaw related information. Grey Level Co-occurrence Matrix (GLCM) features are extracted from MFL images and taken as input parameter to train the neural network. A comparative study on characterization have been carried out using feed-forward back propagation (FFBP) and cascade-forward back propagation (CFBP) algorithms. The results of both algorithms are evaluated with Mean Square Error (MSE) as a prediction performance measure. The average percentage error for length, depth and width are also computed. The result shows that the feed-forward back propagation network model performs better in characterizing the defects.
Boundary control of nonlinearwave equations: An iterative learning control scheme

This paper aims at design and analysis of iterative learning control (ILC) for a class of nonlinear wave equations. Without any simplification or discretization of the 3D dynamics in the time, the space as well as the iteration domains, the learning convergence of ILC is analyzed for the wave equations directly by virtue of the contraction mapping methodology and λ-norm. It is shown that the proposed ILC scheme works well for systems with state-independent or state-dependent nonlinear uncertainties, which has been verified by a simple example.
Expression of SRP-9001 dystrophin and stabilization of motor function up to 2 years post-treatment with delandistrogene moxeparvovec gene therapy in individuals with Duchenne muscular dystrophy

Introduction: Delandistrogene moxeparvovec (SRP-9001) is an investigational gene transfer therapy designed for targeted expression of SRP-9001 dystrophin protein, a shortened dystrophin retaining key functional domains of the wild-type protein. Methods: This Phase 2, double-blind, two-part (48 weeks per part) crossover study (SRP-9001-102 [Study 102]; NCT03769116) evaluated delandistrogene moxeparvovec in patients, aged ≥4 to <8 years with Duchenne muscular dystrophy. Primary endpoints (Part 1) were change from baseline (CFBL) in SRP-9001 dystrophin expression (Week 12), by Western blot, and in North Star Ambulatory Assessment (NSAA) score (Week 48). Safety assessments included treatment-related adverse events (TRAEs). Patients were randomized and stratified by age to placebo (n = 21) or delandistrogene moxeparvovec (n = 20) and crossed over for Part 2. Results: SRP-9001 dystrophin expression was achieved in all patients: mean CFBL to Week 12 was 23.82% and 39.64% normal in Parts 1 and 2, respectively. In Part 1, CFBL to Week 48 in NSAA score (least-squares mean, LSM [standard error]) was +1.7 (0.6) with treatment versus +0.9 (0.6) for placebo; p = 0.37. Disparity in baseline motor function between groups likely confounded these results. In 4- to 5-year-olds with matched baseline motor function, CFBL to Week 48 in NSAA scores was significantly different (+2.5 points; p = 0.0172), but not significantly different in 6-to-7-year-olds with imbalanced baseline motor function (−0.7 points; p = 0.5384). For patients treated with delandistrogene moxeparvovec in Part 2, CFBL to Week 48 in NSAA score was +1.3 (2.7), whereas for those treated in Part 1, NSAA scores were maintained. As all patients in Part 2 were exposed to treatment, results were compared with a propensity-score-weighted external control (EC) cohort. The LSM difference in NSAA score between the Part 2 treated group and EC cohort was statistically significant (+2.0 points; p = 0.0009). The most common TRAEs were vomiting, decreased appetite, and nausea. Most occurred within the first 90 days and all resolved. Discussion: Results indicate robust expression of SRP-9001 dystrophin and overall stabilization in NSAA up to 2 years post-treatment. Differences in NSAA between groups in Part 1 were not significant for the overall population, likely because cohorts were stratified only by age, and other critical prognostic factors were not well matched at baseline.
The thermal conductivity in hybridised graphene and boron nitride nanoribbons modulated with strain

Thermal transport properties in hybridised graphene and boron nitride ribbons (HGBNRs) under different strains are studied by using reverse nonequilibrium molecular dynamics simulations. It is found that the effect of strains on the thermal conductivity is different for different types of strains. When the tensile and shear strains are applied, the thermal conductivity can be modulated at least up to 50% at room temperature as the strain ε ranges from 0 to 0.2. However, when the compressive and flexural strains are respectively applied, the thermal conductivity is insensitive to the variation of the strain. In addition, it is also found that the thermal conductivity of HGBNRs depends sensitively on the dimension of the hybridised ribbon and the relative amount of h-BN to graphene. A brief analysis of these results is given.

Narrow Focus Intonation in Castilian Spanish Absolute Interrogatives

This paper reports the results of an experimental study on the intonation patterns used to communicate narrow focus in Castilian Spanish absolute interrogatives. The results show that three different intonation patterns are used on words in narrow focus in absolute interrogatives. In addition it is found that a tonally marked prosodic boundary following a word in narrow focus and a post-focal reduced pitch range are often used. While this is the first study dedicated to focal intonation in Castilian Spanish absolute interrogatives, a number of studies have addressed focal intonation in Castilian Spanish declaratives. The results of the present study are compared with the results of the studies on declaratives in order to determine what aspects of focal intonation are unique to each sentence type and what aspects are common to focal marking across sentence types.
Sensor-Free Biosensing of Mitral and Aortic Valvular Function During Continuous Flow Left Ventricular Assist Device Support

Continuous flow left ventricular assist devices (CF-LVADs) are miniaturized devices supporting the failing left ventricle and alter the blood flow in the cardiovascular system which may cause severe health complications. Regurgitation and stenosis in mitral and aortic valves may further aggravate complications and limit the efficiency of CF-LVAD support. Within this context, real-time monitoring of the blood flow in the CF-LVAD support will allow early detection of mitral and aortic valve problems and timely intervention before the valvular problems are worsened. Addressing these issues, this study detects mitral regurgitation, stenosis, and aortic regurgitation during CF-LVAD support by monitoring CF-LVAD electrical current. Patient-specific electrocardiograph RR interval time series with normal sinus rhythm were incorporated into a cardiovascular system model including CF-LVAD whilst simulating mild and moderate mitral regurgitation, stenosis, and aortic regurgitation. Spearman rank test was used to analyze the correlation between CF-LVAD electrical current signal waveforms over left ventricular systole and left atrial contraction. Correlation coefficients between the CF-LVAD electrical current signals in normal heart valve function and mild and moderate mitral regurgitation were 0.07 and −0.68. Normal heart valve function and mild and moderate mitral stenosis were 0.82 and 0.68. Within the normal heart valve function and mild and moderate aortic regurgitation, the correlation coefficients are 0.86 and 0.61, respectively. These results suggest that CF-LVAD electrical current signal waveforms can be used for both diagnosis and prognosis of mitral and aortic disorders, thereby representing a potential innovation in the field of both bioelectronics and biosensors.
Géométrie Riemannienne appliquée à la réduction de la dimension de signaux EEG pour les interfaces cerveau-machine

Au cours des dernieres annees, le domaine des interfaces cerveau-machine (brain-computer interfaces, BCI) fondees sur l'elec-troencephalographie (EEG) a connu un interet croissant. Les methodes de l'etat de l'art utilisent les concepts de la geometrie Riemannienne qui permettent de prendre en compte la structure intrinseque des matrices de covariance des signaux EEG pour la classification dans differents paradigmes BCI. Cependant, elles montrent leurs limites lorsque le nombre d'electrodes augmente a cause de la complexite algorithmique et du mauvais conditionnement des matrices. Dans cet article, nous montrons qu'il peut etre avantageux d'utiliser au prealable des methodes de reduction de dimension afin d'augmenter les performances de classification. Nous evaluons deux algorithmes differents et comparons leurs performances face a des modeles sans reduction dans des tâches de classification de signaux EEG. Abstract – In the past few years, there has been an increasing interest among the brain-computer interface (BCI) community in classification algorithms that respect the intrinsic geometry of the spatial covariance matrices of electroencephalographic (EEG) recordings. These methods are based on concepts of Riemannian geometry and, despite demonstrating good performance on several occasions, do not scale well when the number of electrodes increases. In this paper, we show that it may be advantageous to reduce the dimensions of the covariance matrices before performing the classification tasks. We evaluate two methods for reducing the dimension of the covariance matrices of EEG recordings and compare their classification performance on BCI data to models without any dimension reduction.
Greybody Factors for Tachyonic Fields Emitted by Dilatonic Black Strings

We studied in detail the propagation of a massive tachyonic scalar field in the background of a five-dimensional ($5D$) Einstein-Yang-Mills-Born-Infeld-dilaton black string: the massive Klein-Gordon equation was solved, exactly. Next we obtained complete analytical expressions for the greybody factor, absorption cross-section, and decay-rate for the tachyonic scalar field in the geometry under consideration. The behaviors of the obtained results are graphically represented for different values of the theory's free parameters. We also discuss why tachyons should be used instead of ordinary particles for the analytical derivation of the greybody factor of the dilatonic $5D$ black string.

Synthesis, Structure, and Properties of the PbZrO3‐PbTiO3‐Bi(Zn2/3Nb1/3)O3 Ternary Solid Solution System Around the Morphotropic Phase Boundary

PbZrO3‐PbTiO3‐Bi(Zn2/3Nb1/3)O3 ternary solid solution system with various compositions is synthesized in the form of ceramics by solid‐state reaction method. Their crystal structure and electric properties are investigated by X‐ray diffraction, dielectric spectroscopy, ferroelectric and piezoelectric measurements. Studies are mainly focused on two series of compounds 0.95[(1−x)PbZrO3‐xPbTiO3]‐0.05Bi(Zn2/3Nb1/3)O3 and 0.90[(1−x)PbZrO3‐xPbTiO3]‐0.10Bi(Zn2/3Nb1/3)O3, which have their compositions across the morphotropic phase boundary (MPB). It is found that the addition of Bi(Zn2/3Nb1/3)O3 broadens the MPB region of the well‐known lead zirconate titanate (PZT) binary system and leads to a gradually curved MPB line in the pseudobinary phase diagram and a gradually decreased Curie temperature in these two systems. Enhanced remnant polarization, coercive field, and electromechanical properties are found in the ternary solid solution system compared with pure PZT ceramics.
Paragraph-oriented methods for determining the coherence and thematic unity of scientific and technical texts

The subject of the article is to determine the degree of scientific and technical text connectedness using statistical calculations. The aim of the scientific investigation is to study the possibilities of using the coherence of fluctuations in the relative frequencies of keywords in paragraphs to determine the lexical coherence and thematic unity of scientific and technical texts. The task is to develop a method for determining the thematic unity of a text at the set of paragraphs level; to develop a method for determining the coherence of a text at the set of paragraphs level; and to test the developed methods on a collection of documents. The methods used are statistical analysis and computational experiment methods. The following results were obtained. The study has shown that it is advisable to cluster paragraphs as points in the keyword space to determine the degree of scientific and technical text coherence at the level of paragraphs. This opens up the possibility of calculating the degree of thematic unity within the clusters and in the entire text. The degree of text fragments and the whole text coherence is determined by analyzing the sequence of paragraph numbers in the clusters. This makes it possible to formally determine the quality of the material presented in a scientific and technical article or in a textbook. Conclusions. The scientific novelty of the study is as follows: there was refined on the method for determination of the connectedness degree (coherence and thematic unity) of scientific and technical texts at the level of paragraphs by implementation of paragraphs clustering in the keywords space, using the calculation of thematic unity degree inside the clusters and in the overall text, as well as through analysis of paragraphs numbers sequence in clusters in order to determine the degree of text fragments and the overall text coherence. The methods are language-independent, based on clear hypotheses, and complement each other. The methods have an adjusting element that can be used to adapt it to different thematic and stylistic areas. It has been experimentally proved that the proposed methods for the determination of scientific and technical text connectedness are efficient and can provide the framework for information technology of content analysis of scientific and technical texts. The proposed methods do not use WEB resources for syntactic and semantic analysis, providing the possibility to use them autonomously.
Architecture and performance evaluation of fiber-granularity routing networks with supplemental grooming by wavelength conversion

Fiber-granularity routing networks that adopt wavelength-granularity add/drop and a limited number of wavelength converters are proposed. The express parts of nodes can be optical switches, used as fiber cross-connects (FXCs), as they offer low-cost scaling. However, FXCs cannot route optical signals on a wavelength basis, unlike present wavelength cross-connects (WXCs). This routing restriction degrades the statistical multiplexing effect and decreases fiber utilization efficiency. The restriction is slightly relaxed by the use of wavelength-granularity add/drop operations; however, our numerical simulations show that the degradation can reach around 50% when the number of optical paths in a fiber is 25. This substantial degradation is cost-effectively alleviated by introducing wavelength/optical path grooming with a limited number of wavelength converters, which enhances routing flexibility. Numerical simulations show that our network architecture improves routing performance by 86% compared to fiber-granularity routing networks without wavelength converters, and the performance deterioration relative to present WXC-based networks is suppressed to ${\sim}{14}\%$.
A New Design for Improving Amplitude Imbalance of Branch-Guide Coupler Utilizing Branch Structure With Dual Transmission Zeros

This article presents a new design for improving the amplitude imbalance of the branch-guide coupler (BGC) using a novel branch structure. This basic structure consists of a main TE301 mode cavity loaded with an <inline-formula> <tex-math notation="LaTeX">$E$ </tex-math></inline-formula>-plane stub, which is located in the middle of the main cavity and can be considered as a TM110 mode cavity. Through analysis, it is found that this new topology will provide two transmission zeros (TZs), and the positions of the TZs can be independently controlled. Further, the amplitude imbalance of the BGC is greatly improved because of the existence of high- and low-frequency TZs. To verify the design concept for loose- and tight-coupling applications, 10 dB 4-branch and 3 dB 7-branch prototypes are designed, processed, and measured. The measurements show that the 4-branch BGC achieves a coupling of approximately 10.3 dB with ±0.2 dB variation over the full <inline-formula> <tex-math notation="LaTeX">$D$ </tex-math></inline-formula>-band, and the return loss (RL) and isolation are greater than 20 dB. Furthermore, the measurements of the 3 dB 7-branch BGC show that, over the full <inline-formula> <tex-math notation="LaTeX">$D$ </tex-math></inline-formula>-band, the RL and isolation are greater than 20 dB, and the amplitude and phase imbalance are less than 0.3 dB and ±2.2°, respectively. The measurements and simulations are in excellent agreement. To the best of the authors’ knowledge, these are the full-band BGCs with the lowest amplitude imbalance proposed to date. Therefore, the proposed BGCs have significant potential for application in ultrawideband millimeter-wave and submillimeter-wave waveguide systems.
