A single group trial (before – after) on impact of physiotherapeutic intervention package on relief from low back pain of pregnant women

Introduction: More than half of the women have low back pain (LBP) at some point during pregnancy; the intensity of back pain increases as the pregnancy progresses. Such changes increase their risk for musculoskeletal disorders and fall injuries. Aim and Objective: Our study's objective was to estimate the prevalence of LBP in antenatal and postnatal cases of pregnancy in PGIMER, Chandigarh and to ascertain impact of a training intervention on incidence and severity of LBP in the study subjects. Methodology: A single group trial (before and after) on impact of physiotherapeutic intervention package on relief from LBP in pregnant women in between 20 and 35 years of age group were selected. The study duration was one year. The numeric pain rating scale was taken for measuring pain intensity at different levels. Where 0 indicates no pain, 1-3 indicates mild pain (which may be nagging, annoying, and interfering little with activities of daily livings (ADLs)), 4-6 indicates moderate pain (interferes significant with ADLs), and 7-10 indicates severe pain (Disabling, unable to perform ADLs). As per available time, it was decided to include at least 30 subjects in the study. Results: Initially 45 patients were enrolled. Of those, 30 patients were suffering from backache, that is, 67% of the total and 33% did not have any backache. There were no backaches reported in the first trimester, five cases were in the second trimester, and 18 cases were in the third trimester. Of 30 patients, 11 were less than 25 years of age and remaining 19 patients were in the age group of 26-35 years.
Otrokovo doživljanje bivanja v bolnišnici z vidika staršev in medicinskega osebja

V raziskavi je sodelovalo 84 starsev hospitaliziranih otrok in 46 medicinskih sester oziroma tehnikov. Hospitalizacija pomeni za otroke distres, zato aktivira sistem navezanosti na starse. Starsi in medicinsko osebje so ocenili vedenje otrok ob sprejemu v bolnisnico, med bivanjem v njej in ob odpustu. Odgovorili so na vprasanja, kaksen odnos imajo do hospitaliziranega otroka, ali bolnisnicni oddelki imajo igralnico, ali otroke obiskuje bolnisnicna vzgojiteljica ter kdo nudi pomoc otroku s prilagoditvenimi težavami. Ugotovili smo, da obstajajo pomembne razlike v pogostosti razlicnih otrokovih vedenj med razlicnimi obdobji bivanja v bolnisnici. Od nevarnih vzorcev navezanosti sta se izrazila predvsem upiranje in neorganiziranost.
Effectiveness of Automatic Speech Evaluation System in Improving Students’ Self-efficacy in Oral English Learning

: Most college teachers find that Chinese students are not flexible enough in using English and they have poor vocabulary in oral expression and inaccurate pronunciation. This research aims to explore the effect of using Automatic Speech Evaluation (ASE) system on the first-year college students’ oral performance in fluency, accuracy, and integrity: whether teaching oral English through ASE is better than regular instruction and whether this technology can improve the students’ self-efficacy in learning oral English. The findings of the study show that there is a significant difference on the participants’ level of oral competence and self-efficacy in Oral English Learning before and after the use of the ASE system.
Effect of PWHT on the Carbon Migration and Mechanical Properties of 2205DSS-Q235 LBW Joint

The effect of postweld heat treatment (PWHT) on the carbon migration and mechanical properties of the 2205DSS-Q235 laser beam welding (LBW) joint was investigated. The carbon-rich zone (CRZ) and carbon-depleted zone (CDZ) generated at the welding seam/Q235 (WS-Q235) interface as the carbon migration occurred after heat-treated at 600°C, 700°C, and 800°C for 1 h. The softening was found in the CDZ. Only the CRZ in joints heat-treated at 800°C was hardened because of the retaining of high-carbon untempered martensite. The thick CDZ in joints heat-treated at 700°C and 800°C contributed to the tensile fracture and the low elongation. The strength of the joint was roughly determined by the hardness of the fracture zone.
Social media addiction among adolescents: Its relationship to sleep quality and life satisfaction

Existence and uniqueness of steady incompressible impinging flow with finite inlet

In this paper, we discuss the well‐posedness of impinging flow through a semi‐infinitely long nozzle and impacting on a plane. More precisely, given the semi‐infinitely long nozzle with finite inlet, the plane, and the positive incoming horizontal velocity, then there exists a unique smooth solution to the impinging flow. Moreover, there exists a smooth free interface that separates the fluid such that it flows out of different outlets in the downstream.
The Secrecy Capacity of the Semi-Deterministic Wiretap Channel with Three State Information

—Exploiting the channel state knowledge can play a fundamental role in improving security, hence a wiretap channel model with distinct channel state information is considered. In particular, it is assumed that the channel between the transmitter, the legitimate receiver and the eavesdropper is a function of three different states. One of the states is an unknown state, the second one is known to the legitimate receiver and the third state is non-causally known to the encoder. For this setting, a secrecy rate is shown to be achieved using a coding scheme based on structured binning in conjunction with a time-sharing argument. The secrecy capacity for this model is established for the speciﬁc case when the legitimate receiver’s observation is a deterministic function of the the channel input and the states.
The Many Faces of Neurological Neonatal Herpes Simplex Virus Infection

This case series explores the various manifestations of central nervous system (CNS) involvement in neonatal herpes simplex virus (HSV) infection and highlights the challenges involved in their diagnosis and treatment. Neonatal HSV infection is a rare but serious condition that can have significant neurological consequences. The article presents three cases of neonatal HSV infection, all involving the CNS, each characterized by distinct clinical features and outcomes. Case 1 describes a three-week-old male with severe HSV meningoencephalitis resulting in poor response to treatment and death. Cases 2 and 3 describe younger neonates who presented early in the disease course with disseminated infection and skin, eye, and mouth (SEM) lesions. Although both patients had CNS involvement, their outcomes were remarkably favorable. The wide range of clinical presentations of CNS manifestations in neonatal HSV infection, ranging from nonspecific to evident neurological symptoms, underscores the need for a high index of suspicion and comprehensive evaluation to ensure early diagnosis and appropriate treatment. However, it also notes that even with timely treatment, some cases may still have a poor prognosis.
A bivariate generalized geometric distribution with applications

ABSTRACT This paper proposes a bivariate version of the univariate discrete generalized geometric distribution considered by Gómez–Déniz (2010). The proposed bivariate distribution can have a positive or negative correlation coefficient which can be used for modeling bivariate-dependent count data. After discussing some of its properties, maximum likelihood estimation is discussed. Two illustrative examples are given for fitting and demonstrating the usefulness of the new bivariate distribution proposed here.
ACCD: An Adaptive Clustering-Based Collusion Detector in Crowdsourcing (Student Abstract)

Crowdsourcing is a popular method for crowd workers to collaborate on tasks. However, workers coordinate and share answers during the crowdsourcing process. The term for this is "collusion". Copies from others and repeated submissions are detrimental to the quality of the assignments. The majority of the existing research on collusion detection is limited to ground truth problems (e.g., labeling tasks) and requires a predetermined threshold to be established in advance. In this paper, we aim to detect collusion behavior of workers in an adaptive way, and propose an Adaptive Clustering Based Collusion Detection approach (ACCD) for a broad range of task types and data types solved via crowdsourcing (e.g., continuous rating with or without distributions). Extensive experiments on both real-world and synthetic datasets show the superiority of ACCD over state-of-the-art approaches.
The Relationship Between Smoking Cessation and Time Perspective in Patients With Coronary Artery Disease

Background: Coronary artery disease (CAD) is the most common type of cardiovascular disease (CVD) and has a high mortality and morbidity rate. Smoking is one of its important risk factors. The time perspective is the basic cognitive process by which individuals perceive, interpret, and interact with their environment and describes the impact of attention on the past, present, and future. It was hypothesized that this cognitive process can have an effect on decisions to use or quit smoking. Thus, this study evaluated the relationship between smoking cessation and time perspective. Materials and Methods: Overall, 170 patients who were hospitalized with the diagnosis of CAD in Bandar Abbas Shahid Mohammadi hospital were selected for inclusion in this cross-sectional descriptive study. They all had a history of smoking. The subjects were divided into two groups of smokers and previous smokers (smoking cessation at least 3 months ago). Finally, Zimbardo Time Perspective Inventory was used to evaluate the time perspective. Results: In general, 170 patients were surveyed, including 151 males and 19 females. Based on the results, 140 people were smokers and 30 had quit smoking. Those quitting smoking received higher scores on past-positive and future time perspectives (P<0.05). Patients who were smokers had higher scores in the present-hedonistic, present-fatalistic, and future transcendent perspectives, but they were not statistically significant. Conclusion: Although previous evidence confirmed a positive relationship between present time perspective and risky behaviors, our findings failed to prove it. However, people with future time perspectives had less tendency to drug addiction and smoking.
Triptofano no Sono: Uma Revisão Sistemática baseada no Método PRISMA

O sono é um processo biológico que apresenta alternância com períodos de vigília, modulado por hormônios e funções neuronais, tais como mecanismos fisiológicos que modificam a temperatura corporal, produção de hormônios e função cardíaca. Anormalidades no sono podem acarretar em má qualidade de vida e a longo prazo em doenças metabólicas e cardiovasculares. Acredita-se que um aliado para o tratamento das desordens do sono seja o triptofano (TRP), que por sua vez, é um aminoácido precursor da melatonina e serotonina. O TRP e alguns dos seus produtos metabólicos, como serotonina e melatonina, participa da regulação do humor, do sono e dos ritmos circadianos e são usados para tratar insônia e apnéia do sono. O objetivo desta pesquisa foi identificar a eficácia do uso do triptofano no sono através de uma revisão sistemática no modelo PRISMA. A revisão sistemática foi realizada a partir de três bases de dados (PubMed, Lilacs e Scielo). Foram encontrados 1.034 artigos, sendo 876 da PubMed, 157 da Lilacs e 1 da Scielo, após a aplicação dos critérios de elegibilidade foram incluídos 8 artigos na revisão. Os estudos mostraram efeitos positivos da suplementação do triptofano no sono, este aminoácido mostrou-se ser eficaz até mesmo no tratamento de distúrbios relacionados ao sono.

Strong Convergence of a Projection-Type Method for Mixed Variational Inequalities in Hilbert Spaces

Abstract In this article, a projection-type method for mixed variational inequalities is proposed in Hilbert spaces. The proposed method has the following nice features: (i) The algorithm is well defined whether the solution set of the problem is nonempty or not, under some mild assumptions; (ii) If the solution set is nonempty, then the sequence generated by the method is strongly convergent to the solution, which is closest to the initial point; (iii) The existence of the solutions to variational inequalities can be verified through the behavior of the generated sequence. The results presented in this article generalize and improve some known results.
Sensorless Integrated AC–DC Power-Factor Correction (PFC) Converter for BLDCM-CF

The existing brushless direct current motor ceiling-fan (BLDCM-CF) has the demerits of high total harmonics distortion (THD) in the supply current, poor power-factor (PPF), slightly high-power consumption, and a high cost. It limits its use in household and industrial applications. This article presents the sensorless integrated ac–dc power factor correction (PFC) converter for BLDCM-CF with a high step-down gain (SDG) and reduced switch-stress to overcome the power quality problems. Its auxiliary-winding voltage is used as feedback to simplify the control. PFC converter is designed in discontinuous inductor current mode (DICM) with a wide change in dc-link-voltage (15–48 V) for an inherent PFC operation. The ceiling-fan (CF) speed is controlled by utilizing the voltage-speed linearity of the brushless direct current motor (BLDCM) with commutation control of inverter switches to get minimum switching losses. For the sensorless operation of BLDCM, the back EMF method is used to detect the actual rotor position. A laboratory prototype is developed to validate its design and show the presented CF has enhanced performance. Its current THD-1.46% with PF of 0.99885, and it meets IEC-standard 61000-3-2.
Full-image guided method based on confidence coefficient for fast stereo matching

Stereo matching is a challenging problem and is widely used in many applications, including autonomous navigation, 3D-reconstruction and etc. Therefore, we propose a new non-local method for stereo matching in this paper, which is mainly improved in two aspects. On the one hand, all the elements are employed during the step of cost aggregation aiming to handle the textureless regions. Besides, the calculation of aggregation weight is decreased greatly as a result of summing up the penalty terms to propagate weight. On the other hand, different aggregated costs are combined by defining the confidence coefficient instead of assigning weight in conventional methods. We evaluate the performance of our algorithm on the Middlebury dataset. Our model shows excellent results in particular for repetitive textures.
The power of choice over preferential attachment

We introduce a new type of preferential attachment tree that includes choices in its evolution, like with Achlioptas processes. At each step in the growth of the graph, a new vertex is introduced. A fixed number d of possible neighbor vertices are selected independently and with probability proportional to degree. Between them, the vertex with smallest degree is chosen, and a new edge is created. We determine with high probability the largest degree of this graph up to some additive error term.
Design of correct pattern recognition algorithms with minimal instability

A measure of stability for a wide class of pattern recognition algorithms is introduced to cope with overfitting in classification problems. Based on this concept, constructive methods are developed for designing correct (or close to correct) stable algorithms. Such algorithms can be derived either from a set of parametric algorithms of the same model or from algorithms that belong to different models.
Review of numerical models of cavitating flows with the use of the homogeneous approach

The focus of research works on cavitation has changed since the 1960s; the behaviour of a single bubble is no more the area of interest for most scientists. Its place was taken by the cavitating flow considered as a whole. Many numerical models of cavitating flows came into being within the space of the last fifty years. They can be divided into two groups: multifluid and homogeneous (i.e., single-fluid) models. The group of homogenous models contains two subgroups: models based on transport equation and pressure based models. Several works tried to order particular approaches and presented short reviews of selected studies. However, these classifications are too rough to be treated as sufficiently accurate. The aim of this paper is to present the development paths of numerical investigations of cavitating flows with the use of homogeneous approach in order of publication year and with relatively detailed description. Each of the presented model is accompanied by examples of the application area. This review focuses not only on the list of the most significant existing models to predict sheet and cloud cavitation, but also on presenting their advantages and disadvantages. Moreover, it shows the reasons which inspired present authors to look for new ways of more accurate numerical predictions and dimensions of cavitation. The article includes also the division of source terms of presented models based on the transport equation with the use of standardized symbols. ∗Corresponding Author.

Policy gradient finds global optimum of nearly linear-quadratic control systems

We explore reinforcement learning methods for finding the optimal policy in the nearly linear-quadratic control systems. In particular, we consider a dynamic system composed of the summation of a linear and a nonlinear components, which is governed by a policy with the same structure. Assuming that the nonlinear part consists of kernels with small Lipschitz coefficients, we characterize the optimization landscape of the cost function. While the resulting landscape is generally nonconvex, we show local strong convexity and smoothness of the cost function around the global optimizer. In addition, we design a policy gradient algorithm with a carefully chosen initialization and prove that the algorithm is guaranteed to converge to the globally optimal policy with a linear rate
Nonlinear Site Effects: Interest of one Directional - Three Component (1D - 3C) Formulation

Strong ground motions generally lead to both a stiffness reduction and a larger energy dissipation in the soil layers. Thus, in order to study such phenomena, several nonlinear rheologies have been developed in the past. However, one of the main difficulties of using a given rheology is the number of parameters needed to describe the model. In this sense, the multi-surface cyclic plasticity approach, developed by Iwan in 1967 is an interesting choice since the only data needed is the modulus reduction curve. Past studies have implemented this method in one-directional SH wave-propagation (1D-1C). This work, however, aims to study the local site effects by considering one-directional (1D) seismic wave propagation accounting for their three-dimensional nonlinear behavior. The three components (3C) of the outcrop motion are simultaneously propagated into a horizontal multilayer soil for which a three-dimensional constitutive relation is used. The rheological model is implemented using the Finite Element Method. The alluvial site considered in this study corresponds to the Tiber River Valley, close to the historical centre of Rome (Italy). The computations are performed considering the waveforms referred as the 14 October 1997 Umbria-Marche earthquake, recorded on outcropping bedrock. Time histories and stress-strain hysteretic loops are calculated all along the soil column. The octahedral stress and strain profiles with depth and the modulus of acceleration transfer function (surface/outcrop spectral ratios) are estimated in the cases of combining three 1D-1C nonlinear analyses and of 1D-3C conditions, evidencing the influence of threedimensional loading path.
Accurate measurements of the rise and decay times of fast scintillators with solid state photon coun

In this work we present a measurement setup for the determination of scintillation pulse shapes of fast scintillators. It is based on a time-correlated single photon counting approach that utilizes correlation between 511 keV annihilation photons to produce start and stop signals in two, separate crystals. The measurement is potentially cost effective and simple to set up while maintaining an excellent timing resolution of 120 ps. Apart from these advantages this method probes the entire volume of the crystal under investigation rather than a thin layer at the surface. Here, we present a proof-of-concept and first results for the time constants of LYSO.
A Matter of Framing: Analyzing Value Communication in Sustainable Business Models

Sustainable business models refocus value creation beyond customers only toward value creation for various other stakeholders and the natural environment as well. Extant literature acknowledges the importance of translating this stakeholder value into consumer value. However, the frames that could support this translation through different interpretations of stakeholder value are yet to be investigated. This article examines the frames that communicate the value created for other stakeholders as functional, emotional, social, and cost-related value to consumers. Based on the analysis of 17 cases, seven coexisting frames are synthesized based on the ways through which value is translated. These frames highlight the importance of emotional and social value in sustainable business models, contributing a richer understanding of value and how stakeholder value can be translated for consumers. In this regard, the article contributes a distinction between self-related and self-transcendent translations of stakeholder value into consumer value.
