Internet gaming disorder: Its prevalence and associated gaming behavior, anxiety, and depression among high school male students, Dammam, Saudi Arabia

BACKGROUND: Video games have become popular in the last few decades, resulting in an increase in reported negative consequences. This study aimed to assess the prevalence of internet gaming disorder (IGD), its association with gaming behavior, depression, and anxiety in male high school students. MATERIALS AND METHODS: This cross-sectional study involved male high school students in Dammam. Schools were selected using stratified random sampling, and data were collected using a self-administered questionnaire. Data analyzed using SPSS v23.0; the initial analysis included descriptive statistics. Continuous and ordinal variables were compared using t-test or Mann–Whitney U test, and ANOVA or Kruskal–Wallis test, as appropriate; Chi-square test was used for categorical variables. Spearman correlation coefficient was calculated to determine the correlation between IGD score and depression and anxiety scores. RESULTS: A total of 726 high school gamers were involved, 87% of whom were Saudi, with a mean age of 16.92 years and 45% were from public schools. The mean IGD score was 18.12, and the prevalence of IGD was 21.85%. Students who spent ≥4 h/day on weekdays or ≥6 h/day at weekends on videogames and gamers who spent ≥200 Saudi Riyals per month on gaming had significantly higher mean IGD scores (P < 0.001). Gamers who used PC/laptop for gaming had significantly higher IGD scores compared to those who used other devices (P = 0.002). Action, fight, open-world games, and games with violence were associated with significantly higher IGD scores. Among students with IGD, 21.7% had moderately severe/severe depression and 11.4% had severe anxiety. CONCLUSION: IGD is a concerning psychiatric disorder in male high school students. It is associated with certain gaming behavior and other mental problems. We recommend future larger-scale research that includes females as well.
From Regulating Emotions to Less Lonely Screen Time: Parents’ Qualitative Perspectives of the Benefits and Challenges of Adolescent Pet Companionship

Adolescence is a prime developmental period to explore human–pet relationships, particularly given that teens are often relying less on their families, and more on other attachment figures such as peers and pets. However, most research on pet companionship is conducted with adults and young children. Moreover, lived experiences around having pets in households with adolescents are underexplored, particularly from parents’ perspectives. This qualitative interview study of 31 parents/guardians in the Northeast U.S. explored perceptions of the benefits and challenges of having pets for their adolescent’s well-being as well as how adolescents affected their pet’s well-being. Our three main themes for perceived benefits of pets included social (e.g., reducing anxiety), physical (e.g., screen time companionship), and emotional (e.g., regulation of difficult emotions such as anger, loneliness). Challenges to adolescent well-being included such social topics as family tension around unevenly shared responsibilities, physical themes such as problematic animal behaviors, and emotional themes related to grieving the passing of pets. We offer a developmental systems approach to understanding pets within adolescent families, noting future directions for developing family interventions to improve pet–adolescent interactions given the demands of child and pet upbringing during adolescence.
Exoskeleton ageing and its relation to longevity and fecundity in female Australian leaf insects (Phyllium monteithi)

Abstract. Senescence is a decline in reproduction and survival rate with advancing age resulting from deterioration of somatic tissues and systems throughout the body. Age-related somatic changes (somatic ageing) have been studied extensively in vertebrates but are less well known in other animals, including insects. Since adult insects have very limited ability to repair their exoskeleton, somatic ageing could involve deterioration and discolouration of the cuticle. We investigated age-related changes in wing pigmentation and abdominal cuticle necrosis in females of the Australian leaf insect Phyllium monteithi. Adult females varied markedly in the extent and pattern of pigmentation on their bodies, and we found that pigment spots on the forewings increased in size with age in most individuals. As females aged, most individuals also exhibited increasing levels of abdominal cuticle necrosis, resulting in the loss of abdominal cuticle along the margin of the abdomen. Neither the extent of pigmentation nor cuticle loss were clearly associated with reduced fecundity or longevity in the protected laboratory environment, but it remains unknown whether these age-related changes have functional implications in the wild. Our results show that the P. monteithi exoskeleton undergoes complex changes with age, with potential implications for functional traits and fitness.
Does CA-125 Have a Role in Early Diagnosis of Ovarian Malignancy in Non-Menopausal Women?

Objective: Aim of this study is to assess the role of Cancer Antigen (CA-125) in detection of ovarian malignancy in premenopausal women with ovarian mass. Methods: This observational study was carried out in (blinded). It included 200 women who had preliminary diagnosis of adnexal mass whatever its nature. Adnexal masses were detected either clinically or by ultrasound. Results: The study shows distribution of different pathologies of malignancy, stage of malignancy at diagnosis and benign spectrum in investigated population. The study also reveals CA-125 cutoff point 35.1 and sensitivity and specificity reached 93.1% and 92.2% respectively. Area under the Curve (AUC) was 0.998, Positive Prediction Value (PPV) was 91.7% and Negative Prediction Value (NPV) was 92.1. Conclusion: According to our results CA-125 could be suitable as an ovarian cancer detection marker.
A Cascaded Modular Multilevel Inverter Topology Using Novel Series Basic Units with a Reduced Number of Power Electronic Elements

In this study, a new type of cascaded modular multilevel inverters (CMMLIs) is presented which is able to produce a considerable number of output voltage levels with a reasonable number of components. Accordingly, each series stage of the proposed CMMLI is comprised of two same basic units that are connected with each other through two unidirectional power switches without aiming any of the full H-bridge cells. In addition, since the potentiality for generating a higher number of output voltage levels in CMMLIs hinges on the magnitude of the dc voltage sources used in each series unit, in the rest of this paper, four different algorithms for determining an appropriate value for the dc sources’ magnitude are also presented. In the following, a comprehensive topological analysis between some CMMLI structures reported in the literature and proposed structure along with several simulation and experimental results will be also given to validate the lucrative benefits and viability of the proposed topology.
Multi-Robot System Maintained with Distributed Renewable Energy Sources

—It is difficult for robots working in a large outdoor area to receive energy from a stable commercial power source. In this case, renewable energy sources could be used to supply energy to the robot. In this paper, we present a multi-robot autonomy system that obtains energy from distributed small-scale renewable energy sources with limited storage capacity. A model based on an energy production–consumption equilibrium equation was developed to judge whether the robot could survive with the energy obtained from the allocated energy sources, and a heuristic method was proposed to improve robot utility by allocating energy nodes to each robot based on a k-means algorithm and reallocating energy sources in the border region. Finally, a small-scale renewable energy source that transfers energy by means of Wireless Power Transfer (WPT) was constructed, and a charge experiment was conducted to verify the feasibility of the proposed robot energy autonomy system.
PyraPVConv: Efficient 3D Point Cloud Perception with Pyramid Voxel Convolution and Sharable Attention

Designing efficient deep learning models for 3D point cloud perception is becoming a major research direction. Point-voxel convolution (PVConv) Liu et al. (2019) is a pioneering research work in this topic. However, since with quite a few layers of simple 3D convolutions and linear point-voxel feature fusion operations, it still has considerable room for improvement in performance. In this paper, we propose a novel pyramid point-voxel convolution (PyraPVConv) block with two key structural modifications to address the above issues. First, PyraPVConv uses a voxel pyramid module to fully extract voxel features in the manner of feature pyramid, such that sufficient voxel features can be obtained efficiently. Second, a sharable attention module is utilized to capture compatible features between multi-scale voxels in pyramid and point cloud for aggregation, as well as to reduce the complexity via structure sharing. Extensive results on three point cloud perception tasks, i.e., indoor scene segmentation, object part segmentation and 3D object detection, validate that the networks constructed by stacking PyraPVConv blocks are efficient in terms of both GPU memory consumption and computational complexity, and are superior to the state-of-the-art methods.
Effect of Structural Disorder on the Physical Properties of the Pd Based Heusler Alloys: PdCoMnAl, Pd2CoAl and Pd2MnAl

Abstract In this manuscript, we investigate the effect of structural disorder on the physical properties of Pd-based Heusler alloys: PdCoMnAl, Pd2CoAl and Pd2MnAl using first-principles calculations. In fact, we are studying the structural properties of the equatorial quaternary Heusler alloy PdCoMnAl for three phases: type 1, type 2 and type 3, we have carried out this property to determine the most stable phases. The structural properties results show that the phase of type I, of this alloy is the most stable configuration. In addition, the band structures, and density of states calculations results show that this compound exhibits a half-metallic character with a 100% of spin polarization (SP) at the Fermi-level. The total magnetic moment of the Heusler compound is found to be 5.00 µB. Moreover, it is found that the Slater-Pauling is well described for this alloy. On the other hand, concerning total energy of the full Heusler Pd2YAl (Y = Co or Mn) alloys. It is found that such material in L21-type structure is always smaller than in the XA-type structure during the whole lattice variation variety and the L21-type structure is more energetically preferable for the both full alloys. In addition, the density of states at the Fermi level within the spin up and down states show the metallicity of these compounds. Our results show that the quaternary Heusler is a potential candidate for the spintronic applications.
Assessment of Nanoparticle-Mediated Tumor Oxygen Modulation by Photoacoustic Imaging

Photoacoustic imaging (PAI) is an invaluable tool in biomedical imaging, as it provides anatomical and functional information in real time. Its ability to image at clinically relevant depths with high spatial resolution using endogenous tissues as contrast agents constitutes its major advantage. One of the most important applications of PAI is to quantify tissue oxygen saturation by measuring the differential absorption characteristics of oxy and deoxy Hb. Consequently, PAI can be utilized to monitor tumor-related hypoxia, which is a crucial factor in tumor microenvironments that has a strong influence on tumor invasiveness. Reactive oxygen species (ROS)-based therapies, such as photodynamic therapy, radiotherapy, and sonodynamic therapy, are oxygen-consuming, and tumor hypoxia is detrimental to their efficacy. Therefore, a persistent demand exists for agents that can supply oxygen to tumors for better ROS-based therapeutic outcomes. Among the various strategies, NP-mediated supplemental tumor oxygenation is especially encouraging due to its physio-chemical, tumor targeting, and theranostic properties. Here, we focus on NP-based tumor oxygenation, which includes NP as oxygen carriers and oxygen-generating strategies to alleviate hypoxia monitored by PAI. The information obtained from quantitative tumor oxygenation by PAI not only supports optimal therapeutic design but also serves as a highly effective tool to predict therapeutic outcomes.
Efficacy of Polymer-Based Nanomedicine for the Treatment of Brain Cancer

Malignant brain tumor is a life-threatening disease with a low survival rate. The therapies available for the treatment of brain tumor is limited by poor uptake via the blood–brain barrier. The challenges with the chemotherapeutics used for the treatment of brain tumors are poor distribution, drug toxicity, and their inability to pass via the blood–brain barrier, etc. Several researchers have investigated the potential of nanomedicines for the treatment of brain cancer. Nanomedicines are designed with nanosize particle sizes with a large surface area and are loaded with bioactive agents via encapsulation, immersion, conjugation, etc. Some nanomedicines have been approved for clinical use. The most crucial part of nanomedicine is that they promote drug delivery across the blood–brain barrier, display excellent specificity, reduce drug toxicity, enhance drug bioavailability, and promote targeted drug release mechanisms. The aforementioned features make them promising therapeutics for brain targeting. This review reports the in vitro and in vivo results of nanomedicines designed for the treatment of brain cancers.
The Moderating Effect of Mindfulness on the Relationship Between Problematic Smartphone Usage and Depression, Anxiety, and Stress

The purpose of the current study was to investigate mindfulness as a moderator in the relationship between problematic smartphone usage (PSU) and ratings of depression, anxiety, and stress. Participants were 168 undergraduates from a university in southern California, who completed an online survey measuring smartphone addiction, mental health markers, and mindfulness. The current study also investigated the relationship between one’s objective smartphone screen time and ratings of PSU, depression, anxiety, and stress through Pearson’s product-moment correlations and hierarchical regression analyses. Results indicated that, for individuals with high mindfulness, mindfulness significantly moderated the relationship between PSU and anxiety and stress, but not depression. For those high in mindfulness, higher PSU was associated with higher anxiety (B = 0.11, SE = 0.04, 95% CI [0.02, 0.19], p = .02) and stress (B = 0.12, SE = 0.05, 95% CI [–0.08, 0.09], p < .001), an unexpected finding. The relationships between PSU and both anxiety and stress were nonsignificant for those low in mindfulness (p = .80 in both cases). Among the full sample, more objective screen time was associated with more depression (r = .25, p < .001) but was not linked to PSU (r = .13, p = .13). Implications are discussed, as well as limitations and suggestions for future research.
Design and Experimental Investigation of Thermoelectric Generators for Wearable Applications

A critical challenge in using thermoelectric generators (TEGs) for charging the portable or wearable electronics has been their limited outputs, as available temperature differential on human body (∆Text) is typically less than 10 K. Furthermore, the thermal resistance (Rth) at the TEG–air interface often overwhelms Rth of TEG itself, which makes the temperature differential within the TEG merely a small fraction of ∆Text. Here, the designs of TEG systems for wearable applications based both on theory and systematic experiments are studied. First, this study fabricates the TEGs having different fill factors (equivalently, varied internal Rth of the TEGs) and finds an optimum fill factor that is determined by both thermal matching condition and the electrical contact resistance. Next, to investigate the effects of heat sink and external air flow, this study combines plate fin heat sinks with the TEGs and evaluates their performance under three different convection conditions: natural convection, and convection with either parallel or impinging flow. Lastly the effect of Rth at the skin–TEG interface is studied. Although the TEG system produces an output power of 126 µW cm−2 (∆Text = 7 K) on a smooth heat source (Cu heater), it generates reduced power of 20 µW cm−2 (∆Text = 6 K) on wrist (uneven heat source).
20F Power Measurement for Generation IV Sodium Fast Reactors

The Phenix nuclear power plant has been a French Sodium Fast Reactor (SFR) prototype producing electrical power between 1973 and 2010. The power was monitored using ex-core neutron measurements. This kind of measurement instantly estimates the power but needs to be often calibrated with the heat balance thermodynamic measurement. Large safety and security margins have then been set not to derive above the nominal operating point. It is important for future SFR to reduce this margin and working closer to the nominal operating point. This work deals with the use of delayed gamma to measure the power. The main activation product contained in the primary sodium coolant is the 24Na which is not convenient for neutron flux measurement due to its long decay period. The experimental study done at the Phenix reactor shows that the use of 20F as power tagging agent gives a fast and accurate power measurement closed to the thermal balance measurement thanks to its high energy photon emission (1.634 MeV) and its short decay period (11 s).
Treating a rare mid-term complication of transapical transcatheter aortic valve implantation (TAVI): a case report

Abstract We report the case of a patient who underwent transcatheter aortic valve implantation via left anterior mini-thoracotomy in whom a periapical subcutaneous collection appeared in the anterior thoracic wall 18 months after the procedure. The tissue defect was efficaciously repaired via intercostal artery perforator flap, preserving the thoracodorsal and internal mammary arteries.
Performance, Blood Lipid Profile, and the Expression of Growth Hormone Receptor (GHR) and Insulin-like Growth Factor-1 (IGF-1) Genes in Purebred and Crossbred Quail Lines

Simple Summary Poultry breeding programs are established to ameliorate the genetic potential of domestic birds through a selection process and crossbreeding programs. In this context, crossbreeding has been considered as an essential tool to produce favorable genotypes, which are affected by different genetic resources and non-genetic factors. Thus, the aim was to evaluate the impact of crossing white and brown quail lines on growth performance, carcass traits, and the relative expression of growth-related genes. The crossbred WBQ quail line (male white × female brown) exhibited a significantly greater dressing percentage and better feed conversion ratio (FCR), as well as higher mRNA expression of growth hormone receptor (GHR) and insulin-like growth factor-1 (IGF-1) genes. Abstract The aim was to evaluate the performance, blood lipid profile, and the relative expression of growth-related genes in purebred white and brown quail lines and their crossbred lines. A total of 240 one-day-old Japanese quail chicks of white and brown line, their crossbred line (WBQ: male white × female brown), and reciprocal crossbred line (BWQ: male brown × female white) were divided into four equal groups (60 birds each). The white quail line showed significantly higher final body weight, daily gain, and feed intake compared with the other quail lines (p < 0.001). Meanwhile, both crossbred quail lines (WBQ and BWQ) showed significantly lower FCR compared with both purebred quail lines (p = 0.001). Both crossbred quail lines showed greater dressing percentages compared with both purebred quail lines (p = 0.038). The brown quail line showed significantly (p = 0.05) higher levels of serum triglycerides and VLDL compared with the white and BWQ lines. The WBQ crossbred line exhibited significantly higher mRNA expression of GHR and IGF-1 genes compared with other quail lines (p < 0.001). Both crossbred lines (WBQ and BWQ) exhibited negative heterosis percentages for body weight (−4.39 and −3.90%, respectively) and feed intake (−10.87 and −14.59%, respectively). Meanwhile, heterosis percentages for FCR (−6.46 and −9.25%, respectively) and dressing percentage (7.54 and 6.38%, respectively) were improved in both crossbred lines. The WBQ line showed high heterosis percentages for the expression of GHR and IGF-1 genes (52.28 and 88.81%, respectively). In conclusion, the WBQ line exhibited significantly greater dressing percentage and better FCR, as well as higher mRNA expression of GHR and IGF-1 genes. These results may be helpful to improve breeding programs and to develop commercial lines of meat-type Japanese quail.
HFF-SRGAN: super-resolution generative adversarial network based on high-frequency feature fusion

Abstract. At present, generative adversarial network (GAN) has made outstanding progress for image super-resolution (SR), solving the problem of edge smoothing in SR images. Nevertheless, there are also problems with a lack of texture details, noise, and artifacts. The high-frequency (HF) information of an image is significant for keeping the texture part of the reconstructed image, and the introduction of HF information can increase the learning ability of super-resolution generative adversarial network (SRGAN) for the image features, so we propose a super-resolution GAN based on high-frequency feature fusion (HFF-SRGAN), which can increase the texture detail of the reconstructed image and reduce the noise and artifacts with less computational cost. Experimental results show that our algorithm evaluates significantly better than SRGAN and has significant advantages in texture details and noise compared with other SR algorithms.
Genome-wide identification and response stress expression analysis of the BES1 family in rubber tree (Hevea brasiliensis Muell. Arg.)

Brassinolide (BR) plays an important role in plant growth, development, and the adaptation adversity process. Moreover, BRI1-EMS-SUPPRESSOR 1 (BES1) genes are crucial transcription factors (TFs) in the BR signaling pathway. To realize the function of HbBES1 family is helpful to improve genetic resources for rubber tree breeding. Based on the rubber tree database, we used bioinformatics to characterize physicochemical properties, gene structure, cis-elements, and expression patterns. These results indicated that there were nine BES1 members in rubber tree, which we named HbBES1-1 to HbBES1-9 and divided into two groups (I and II) based on their genetic relationships. HbBES1 genes in the same group shared similar gene structures and motifs. Cis-acting element analysis showed that the promoter sequences of HbBES1 genes contained many regulator elements that were related to hormone and stress, indicating that HbBES1 genes might be involved in the regulation of hormone and stress signal pathways. Our analysis of tissue specificity revealed that all of the nine HbBES1 members expressed highly in branches. Gene expression profiles under different hormone treatments showed that the HbBES1 gene family was induced to varying degrees under different hormones, HbBES1-3 and HbBES1-9 were extremely induced by ethylene (ETH). These results lay the foundation for further exploration of the molecular mechanism of the BES1 gene family, especially HbBES1-3 and HbBES1-9, regulating plant stress tolerance in rubber tree.
