Gender, Self-silencing, and Identity among School and out of School Emerging Adults

This study aimed to examine the relationship between adolescents' psychological resilience and attachment styles. This research was designed according to the correlational design, which is one of the quantitative research methods. The population of the research consists of high school students studying in Şahinbey District of Gaziantep. The sample of the research is 570 students in 3 Anatolian High Schools, 2 Vocational and Technical Anatolian High Schools, and 1 Imam Hatip High School, determined randomly by the stratified sampling method, n done class in each of the 9, 10, 11 and 12 grades, determined by the random cluster sampling method. The Adolescent Psychological Resilience Scale and the Three Dimensional Attachment Styles Scale were used to measure attachment styles. In the study, the relationship between family support, peer support, school support, adaptation, empathy, and struggle determination, which are the sub-dimensions of the Adolescent Psychological Resilience Scale, and the sub-dimensions of the Three-Dimensional Attachment Styles Scale, between the secure, avoidant, and anxious-indecisive attachment data sets, were examined with canonical correlation analysis. As a result of the canonical correlation analysis, a significant relationship was found between psychological resilience and attachment styles, and the common variance shared between data sets was found to be 44.1%.
Association between Chronotype and Physical Behaviours in Adolescent Girls

The aim of this study was to (1) describe accelerometer-assessed physical behaviours by chronotype, and (2) examine the association between chronotype and accelerometer-assessed physical behaviours in a cohort of adolescent girls. Chronotype (single question) and physical behaviours (GENEActiv accelerometer on the non-dominant wrist) were assessed in 965 adolescent girls (13.9 ± 0.8 years). Linear mixed-effects models examined the relationships among chronotype and physical behaviours (time in bed, total sleep time, sleep efficiency, sedentary time, overall, light and moderate-to-vigorous physical activity) on weekdays and weekend days. Over the 24 h day, participants spent 46% sedentary, 20% in light activity, 3% in moderate-to-vigorous physical activity, and 31% in ‘time in bed’. Seventy percent of participants identified as ‘evening’ chronotypes. Compared to evening chronotypes, morning chronotypes engaged in less sedentary time (10 min/day) and had higher overall physical activity (1.3 mg/day, ~30 min of slow walking) on weekdays. Most girls identified as evening chronotypes with a large proportion of their day spent sedentary and a small amount in physical activities which may be exacerbated in evening chronotypes on weekdays. The results maybe be important for programmes aiming to promote physical activity in adolescent girls.
Predictors of Pneumothorax in People With COVID-19 Pneumonia: A Multicenter Retrospective Investigation

This multicenter retrospective investigation aimed to identify predictors of pneumothorax (PTX), pneumomediastinum (PM), and subcutaneous emphysema (SE) in patients with COVID-19 pneumonia admitted to the ICU. A total of 256 patients were included, with 128 in the case group and 128 in the control group. The study sample consisted of predominantly male patients with a mean age of around 53 years and a high prevalence of comorbidities. Significant predictors of PTX, PM, and SE included the presence of coronary artery disease, non-rebreather mask usage, high-flow oxygen therapy, mechanical ventilation, pressor usage, inpatient dialysis, steroid usage, sedative usage, narcotic usage, paralytic usage, elevated C-reactive protein levels, increased lung infiltration, the presence of PM and SE, mode of ventilation, duration of various respiratory support interventions, and severity of illness as indicated by APACHE and SOFA scores. These findings have important implications for the clinical management of patients with COVID-19 pneumonia, as they may help identify and closely monitor at-risk individuals, allowing for timely intervention and potentially improving clinical outcomes. Future research should focus on validating these predictors in larger cohorts and investigating the underlying mechanisms to develop targeted preventive and therapeutic strategies.
Theoretical Derivation of a Telephone-Based Health Coaching Intervention for Promoting Physical Activity and Healthy Nutrition

Present research regarding interventions to change behavior suffers from insufficient communication of their theoretical derivation. This insufficient communication is caused by the restrictions imposed by most of the relevant scientific journals. This impedes further intervention development. In this article, a telephone-based health coaching (TBHC) intervention is introduced using a format outside these restrictions. This intervention is seen as a combination of (1) the activities performed with the target persons, i.e., its core, and (2) measures to ensure the quality of the intervention. The theoretical derivation of the core is presented. The core is seen to consist of (1) the style of coach–patient interaction and (2) the contents of this interaction. The style of coach–patient interaction was derived from self-determination theory and was concretized using motivational interviewing techniques. The contents of the coach–patient interaction were derived from the health action process approach and were concretized using behavior-change techniques. The derivation led to (1) a set of 16 coaching tools referring to the different states in which a patient might be and containing state-specific recommendations for performing the coaching session, and (2) guidelines for selecting the appropriate coaching tool for each session. To ensure the quality of the intervention, a coach-training program before and supervision sessions during the TBHC were added.
How do elementary students read poetry together? Elementary students’ reading practices using digital annotations

The Zoom platform provided students in recent online classes, which had been necessitated by COVID-19, with opportunities for active expression using digital annotations. This study explores the experience of elementary students reading poetry using digital annotations and its usefulness as social constructivist reading. As such, we conducted a case study of an out-of-school literature class that used Zoom annotations, and collected data through participatory observation, activity materials, and interviews from 16 participating students. The data were analyzed by coding and categorizing common themes in two processes—annotation generating and sharing. We found that the digital annotations facilitated students’ comprehension of challenging texts. They shared their thoughts and reflected on each other’s opinions while generating and sharing annotations and socially constructing their appreciation. Digital annotations are significant in that they reveal the cooperative reading processes of students transparently, and they allow social annotations in literature classes in accordance with the interests and needs of the elementary students.
The association between Patient Assessment of Chronic Illness Care Scores and quality of life in type 2 diabetes patients

Background: Chronic illness care is an important factor for health promotion in diabetes since it affects health outcomes such as quality of life. Aims: The aim of this study was to investigate the relationship between the Patient Assessment of Chronic Illness Care and the quality of life in type 2 diabetes patients. Methods: The study used a cross-sectional and correlational design. The sample included 317 patients with type 2 diabetes. A socio-demographic and disease-related questionnaire form, the Patient Assessment of Chronic Illness Care (PACIC) scale and the WHOQOL-BREF Quality of Life Scale were used to collect data. Results: According to the regression analysis, the stronger predictor affecting all domains of quality of life was the overall PACIC. This study demonstrated the importance of satisfaction level of chronic illness care in the improvement of quality of life. Therefore, the factors affecting the satisfaction level with chronic care services should be determined to improve the quality of life of patients. In addition, healthcare based on the chronic-care model should be provided in the care of the patients. Conclusions: PACIC had an important effect on quality of life of the patients. This study demonstrated the importance of satisfaction level on chronic illness care in the improvement of quality of life.
From Support Vector Machines to Hybrid System Identification

The thesis focuses on three nonlinear modeling problems: classification (or pattern recognition), regression (or function approximation) and hybrid system identification. Amongst existing approaches, Support Vector Machines (SVMs) offer a general framework for both nonlinear classification and regression. These recent methods, based on statistical learning theory, rely on convex optimization to train black-box models with good generalization performances. The study first focuses on the evolution of these models towards grey-box models, which can benefit at the same time from the universal approximation capacity of black-box models and from prior knowledge. In particular, the thesis proposes a general framework for the incorporation of a wide variety of prior knowledge in SVMs for regression, which leads to a learning algorithm written as a convex optimization program. The last part of the thesis proposes to extend SVMs to the identification of hybrid systems, that switch between different dynamics. In this context, the classification and regression problems are intrinsically mixed together and cannot be considered separately. A method based on non-convex optimization is proposed to solve these problems simultaneously. The resulting algorithm is able to deal with hybrid systems switching between arbitrary and unknown dynamics.
GLP-1 Increases Circulating Leptin Levels in Truncal Vagotomized Rats

GLP-1 is a gastro-intestinal hormone acting within the gut/brain axis for energy balance regulation. We aimed to evaluate the role of the vagus nerve in whole-body energy homeostasis and in mediating GLP-1 effects. For this, rats submitted to truncal vagotomy and sham-operated controls underwent a comprehensive evaluation, including eating behavior, body weight, percentage of white (WAT) and brown adipose tissue (BAT), resting energy expenditure (REE) and acute response to GLP-1. Truncal vagotomized rats had significantly lower food intake, body weight, body weight gain, WAT and BAT, with a higher BAT/WAT ratio, but no significant difference in REE when compared to controls. Vagotomized rats also had significantly higher fasting ghrelin and lower glucose and insulin levels. After GLP-1 administration, vagotomized rats depicted a blunted anorexigenic response and higher plasma leptin levels, as compared to controls. However, in vitro stimulation of VAT explants with GLP-1 resulted in no significant changes in leptin secretion. In conclusion, the vagus nerve influences whole-body energy homeostasis by modifying food intake, body weight and body composition and by mediating the GLP-1 anorectic response. The higher leptin levels in response to acute GLP-1 administration observed after truncal vagotomy suggest the existence of a putative GLP-1-leptin axis that relies on the integrity of gut–brain vagal pathway.
INFLOW GENERATION TECHNIQUE FOR LARGE EDDY SIMULATION OF TURBULENT BOUNDARY LAYERS

When simulating turbulent flows using Large-Eddy Simulations (LES) or Direct Numerical Simulations (DNS), imposing correct instantaneous flow quantities at the inflow boundary is a challenge. Indeed, inflow fluctuations need to preserve the turbulent characteristics of the upstream flow that is not simulated. In this thesis, the rescaling recycling method for imposing boundary conditions at the inflow of turbulent boundary layer simulations is developed. The inflow conditions are rendered more physically meaningful by rescaling the instantaneous solution from an internal plane normal to the wall located inside the computational domain using self-similarity of the boundary layer velocity profile at each time step of the simulation. Thus the fluctuations at the inflow incorporate correct turbulent structures. This operation enables a reduction of the needed computational domain. In addition, the rescaling recycling method was implemented in a finite element software using unstructured meshes to expand its application to curved domains (pipes, contracting or expanding nozzles). The important issue when using unstructured meshes is that the recycle plane from which the solution is rescaled is virtual and as such the solution must first be interpolated on that plane before the method can be applied. In this thesis, the LES solutions are presented for zero pressure gradient flat plate turbulent boundary layer using two different scaling laws. First the scaling law developed by Lund, Wu and Squires (LWS) is used. An alternative scaling is also developed based on the theory by George and Castillo that incorporates the local Reynolds number dependence. It was found that the alternative scaling gives statistically similar flow profiles to those obtained by the LWS scaling, but the Reynolds number based on momentum thickness was 3% higher. The numerical results were found to be in good agreement with experimental data.
Multiplex Lithographic SERS Aptasensor for Detection of Several Respiratory Viruses in One Pot

Rapid and reliable techniques for virus identification are required in light of recurring epidemics and pandemics throughout the world. Several techniques have been distributed for testing the flow of patients. Polymerase chain reaction with reverse transcription is a reliable and sensitive, though not rapid, tool. The antibody-based strip is a rapid, though not reliable, and sensitive tool. A set of alternative tools is being developed to meet all the needs of the customer. Surface-enhanced Raman spectroscopy (SERS) provides the possibility of single molecule detection taking several minutes. Here, a multiplex lithographic SERS aptasensor was developed aiming at the detection of several respiratory viruses in one pot within 17 min. The four labeled aptamers were anchored onto the metal surface of four SERS zones; the caught viruses affect the SERS signals of the labels, providing changes in the analytical signals. The sensor was able to decode mixes of SARS-CoV-2 (severe acute respiratory syndrome coronavirus two), influenza A virus, respiratory syncytial virus, and adenovirus within a single experiment through a one-stage recognition process.
Finite‐time formation tracking control for multiple vehicles: A motion planning approach

This paper addresses the finite‐time formation tracking problem for multiple vehicles with dynamics model on SE(3) (the specific Euclidean group of rigid body motions), under the condition that the tracking time is preassigned according to the task requirements. By using Pontryagin's maximum principle on Lie groups, a class of finite‐time optimal tracking control laws are designed for vehicles to track a desired trajectory within a given finite time. Meanwhile, the corresponding cost function is minimized. Furthermore, a tracking‐time lower bound is derived for multi‐vehicle systems with control constraints. Finally, an illustrative example is provided to demonstrate the effectiveness of the proposed control laws. Copyright © 2015 John Wiley & Sons, Ltd.
Approximation Techniques for Incompressible Flows with Heterogeneous Properties

Approximation Techniques for Incompressible Flows with Heterogeneous Properties. (August 2010) Abner Jonatan Salgado Gonzalez, B.S., Saint Petersburg State Polytechnic University; M.S., Saint Petersburg State Polytechnic University Chair of Advisory Committee: Dr. Jean-Luc Guermond We study approximation techniques for incompressible flows with heterogeneous properties. Specifically, we study two types of phenomena. The first is the flow of a viscous incompressible fluid through a rigid porous medium, where the permeability of the medium depends on the pressure. The second is the flow of a viscous incompressible fluid with variable density. The heterogeneity is the permeability and the density, respectively. For the first problem, we propose a finite element discretization and, in the case where the dependence on the pressure is bounded from above and below, we prove its convergence to the solution and propose an algorithm to solve the discrete system. In the case where the dependence is exponential, we propose a splitting scheme which involves solving only two linear systems. For the second problem, we introduce a fractional time-stepping scheme which, as opposed to other existing techniques, requires only the solution of a Poisson equation for the determination of the pressure. This simplification greatly reduces the computational cost. We prove the stability of first and second order schemes, and provide error estimates for first order schemes. For all the introduced discretization schemes we present numerical experiments, which illustrate their performance on model problems, as well as on realistic ones.
Synthesis and Biological Evaluation of O6-Aminoalkyl-Hispidol Analogs as Multifunctional Monoamine Oxidase-B Inhibitors towards Management of Neurodegenerative Diseases

Oxidative catabolism of monoamine neurotransmitters by monoamine oxidases (MAOs) produces reactive oxygen species (ROS), which contributes to neuronal cells’ death and also lowers monoamine neurotransmitter levels. In addition, acetylcholinesterase activity and neuroinflammation are involved in neurodegenerative diseases. Herein, we aim to achieve a multifunctional agent that inhibits the oxidative catabolism of monoamine neurotransmitters and, hence, the detrimental production of ROS while enhancing neurotransmitter levels. Such a multifunctional agent might also inhibit acetylcholinesterase and neuroinflammation. To meet this end goal, a series of aminoalkyl derivatives of analogs of the natural product hispidol were designed, synthesized, and evaluated against both monoamine oxidase-A (MAO-A) and monoamine oxidase-B (MAO-B). Promising MAO inhibitors were further checked for the inhibition of acetylcholinesterase and neuroinflammation. Among them, compounds 3aa and 3bc were identified as potential multifunctional molecules eliciting submicromolar selective MAO-B inhibition, low-micromolar AChE inhibition, and the inhibition of microglial PGE2 production. An evaluation of their effects on memory and cognitive impairments using a passive avoidance test confirmed the in vivo activity of compound 3bc, which showed comparable activity to donepezil. In silico molecular docking provided insights into the MAO and acetylcholinesterase inhibitory activities of compounds 3aa and 3bc. These findings suggest compound 3bc as a potential lead for the further development of agents against neurodegenerative diseases.
Biomechanical Analysis of 4-strand and 5-strand Graft for Anterior Cruciate Ligament Surgical Procedure: A Comparative Review

Anterior cruciate ligament (ACL) injuries, at present, are treated through two different surgical reconstruction procedures, specifically autografts and allografts. Bone-patellar-tendon-bone (BPTB) and Hamstring grafts are the most utilized surgical procedures for ACL injuries. These methods proved to be the most successful in surgical operations. Besides these methods, configurations of the grafts are then selected based on several factors. However, using four or five strand grafts are already considered as the most ideal option. Despite the significant addition of grafts in the orthopedic field of study, substantial research concerned with the biomechanics of four and five strand grafts are still limited. In this study, the biomechanics of four and five strand graft configurations were analyzed through a comprehensive review of existing literatures on the ultimate load failure, stress, stiffness, diameter, and post operative results. Results have shown that differences in diameter are of the most concern since this proved to be an advantage of 5-strand grafts. The remaining factors proved to be insignificant in determining which is more advantageous.
Isolation Enhancement in a Two-Element MIMO Antenna Using Electromagnetic Metamaterial

In this manuscript, a planar, uni-layer two-port multiple-input multiple-output (MIMO) antenna covering the n77/78/79 5G bands is presented. An elliptical-shaped artificial metamaterial structure is used as a decoupling structure to restrict surface current and improve isolation between MIMO antenna elements. The prospective MIMO antenna element is made up of a slotted monopole, 50-ohm feeding line, and a partial ground conductor. For miniaturization, an inverted T-shaped slot is loaded on the radiator of the unit cell. The effective material properties of the suggested ellipse-shaped artificial material are estimated to assess its metamaterial behavior. The proposed MIMO antenna operates from 3300 MHz to 5000 MHz, covering the n77/78/79 5G frequencies. The performance of the presented 5G MIMO antenna is validated using the CST Microwave Studio and Ansys HFSS EM tools.
The Catheter and Guidewire Operating Systems of Vascular Interventional Surgical Robots: A Systematic Review

Vascular interventional surgical robots (VISR) assisted doctors in surgery can not only protect doctors from X-ray radiation, but also improve the accuracy of surgery. The catheter and guidewire operating systems with master-slave operation mode play an important role in VISR. In recent years, the operating systems have gradually become a research hotspot. After nearly two decades of development, they have made great progress, but there are still some problems to be solved. This review first introduces the research necessity and development history of these operating systems. Then, we summarize the research direction of operating systems from the perspective of hardware devices and algorithms. In the hardware devices, we analyzed the catheter and guidewire operating mechanisms, contact force detection devices, master operating mechanisms and master force feedback devices. In the algorithm, we introduce the bilateral control methods, security strategies and skill evaluation methods. Next, we discuss the actual performance and shortcomings of the operating systems from the perspective of clinical application. Finally, we summarize the current problems of the operating systems and propose the future development direction. This review is helpful for researchers to understand the current situation, and provides a reference framework of catheter and guidewire operating system.
Effects of Walking Together in a Co-Located Virtual Reality Game

This paper details a within-subjects study exploring how two lo-comotion techniques affect players' experiences while playing a co-located virtual reality (VR) game. The participants played a two-versus-two game, reminiscent of laser tag, in a $14\mathrm{m}\times 14\mathrm{m}$ arena, and they moved around in the arena either by physically walking or by using VR controller while standing. When walking, participants reported significantly higher social presence directed at their team-mates and significantly lower simulator sickness. Moreover, they found walking significantly more natural, they were significantly more likely to forget that they were using controllers, and they were significantly more concerned with keeping distance to other players.
