LiFi-Based D2D Communication in Industrial IoT

This article analyzes the performance of light fidelity (LiFi)-based device-to-device (D2D) communication in industrial Internet-of-Things (IIoT). We present a comprehensive analysis of mobility management of D2D communication in industrial LiFi networks. Using the semiangle at half illuminance of the AP and D2D transmitting IIoT, a coverage model for the D2D communication range is derived. By adopting stochastic geometry, closed-form expressions for mode selection rate and residence time are derived as functions of the AP density, IIoT density, and velocity. The results have shown that high velocity and denser deployment cause a decrease in the average D2D residence time and an increase in the average D2D transition rate or vice versa. The proposed analytical models are then verified with Monte Carlo simulation results. The results provide system-level design insights.
Does Institutional Quality Matter for the IDP Hypothesis? Evidence from Emerging Europe

The study empirically explores the relationship between OFDI and the home country’s institutional quality by employing a panel of 23 European emerging countries between 2000 and 2019. In doing so, the study employs the VECM estimation procedure. The key findings of this research indicate that the rate of adjustment to reach long-run equilibrium in European post-transition countries is lower than in European transition countries. In conclusion, there is evidence, for the period being investigated, of causality between the home country’s institutional quality and OFDI in both regions. Also, most of the transition countries are still in the process of building the institutional environment, with many institutional voids and different starting points of their internalization process. In fact, most of the countries, especially European transition countries, are in stage 2 or stage 3 of their investment development path (IDP) development, where IFDI stock still remains higher than OFDI stock.
Research on the Phenomenon of Chinese Residents’ Spiritual Contagion for the Reuse of Recycled Water Based on SC-IAT

Recycled water has been widely recognized in the world as an effective approach to relieve the issue of water shortage. Meanwhile, with several decades of development, the insufficiency of technology is no longer the primary factor that restricts the popularization of recycled water. What makes it difficult to promote the concept of reusing recycled water in China? To solve this issue, a special experiment on the public’s attitude towards the reuse of recycled water was designed based on a Single Category Implicit Association Test (SC-IAT), so as to avoid factors like social preference that can influence the survey results, and to gain the public’s negative implicit attitude towards reusing recycled water reuse, which is close to the public’s real attitude to it. From the perspective of implicit attitude, this research testifies the “spiritual contagion” phenomenon of the public, which refers to refusing recycled water reuse because recycled water is made from sewage treatment. By comparing the implicit attitude to recycled water reuse with the explicit attitude that is acquired from self-reporting questionnaires about reusing recycled water, this research finds that the implicit attitude is more positive than the explicit attitude, which accounts for the phenomenon of “best game no one played” in the promotion of the recycled water reuse, that is, the public though applauding the environment-friendly policy, will not actually use the recycled water.
Overexpression of hsa-miR-30a-5p and non-obstructive azoospermia: A case-control study

Abstract Background Some previous human and animal studies have supported the idea that KDM3A down-regulation might be the main cause of male infertility, especially in non-obstructive azoospermia (NOA). The regulatory role of micro-RNAs (miRNA) has been investigated in the development of male infertility. Objective The expression level of hsa-miR-30a-5p in azoospermia was evaluated to reveal its possible association with the etiology of male infertility. Materials and Methods In this case-control study, 30 men with azoospermia (19 of whom had NOA) were selected as the case individuals, and 11 men with obstructive azoospermia (OA) were selected as control individuals. The best miRNA with the strongest ability to target the KDM3A gene was detected via comprehensive bioinformatics analysis. Reverse transcriptase quantitative polymerase chain reaction was used to assess the expression level of hsa-miR-30a-5p. After analyzing the data, the expression level of hsa-miR-30a-5p wascompared between men with NOA and men with OA. Results The findings supported the idea that hsa-miR-30a-5p is the miRNA with the best ability to target the KDM3A transcript. The expression analysis of hsa-miR-30a-5p indicated a significant overexpression (p = 0.04) in men with NOA compared to in men with OA. Conclusion Hsa-miR-30a-5p was overexpressed in men with NOA compared to in control individuals. Hsa-miR-30a-5p could target the KDM3A transcript and may suppress its expression.
Selection of Additive Manufacturing Machine Using Analytical Hierarchy Process

3D printing or additive manufacturing (AM) is considered to be the most important technology among the emerging technologies. 3D printing technology is considered as an alternative to the conventional manufacturer machine traditionally used in the manufacturing sector. 3D printing technology is generally classified into seven types. Each type of 3D printing technology has its separate own uniqueness (i.e., operation, material usage, and no wastage). The price of a manufactured item includes all its costs. The most important of these is to take into account the price of the machine being manufactured and the features of the machine. Moreover, the price of the product produced in AM will depend on all the costs required to produce it. Then, it is possible to reduce the cost of the product by choosing the AMM that has significant features and the right price. Therefore, this paper aims to solve a decision-making problem from the AMM selection by using one of the multicriteria decision-making (MCDM) tools, i.e., analytical hierarchy process (AHP). This paper outcome is meant to meet the expectation of end-users. As an initial step, the Micro, Small, and Medium Enterprise (MSME) company gets quotations from some AM companies to choose a type of AM machine known FDM for its structure product and doll product. The first step is to select the most appropriate machines based on cost, size/volume, extruder type, and weight of the machine. Criteria for AHP are derived from decision-makers. Also, in AHP, the pair-wise matrix is obtained from the decision-makers by answering the standard Saaty’s scale criteria questions. In this paper, such a selection method is explored. The outcome of this paper may vary depending on the expectations of the decision-makers. The end of this paper helps to choose the AMM with the right price and features to suit the decision-makers.
Clinical and laboratory responses to tigecycline in children

The frequency of multidrug‐resistant bacterial infections is increasing worldwide. Tigecycline may be an important option for children with life‐threatening nosocomial infections due to multidrug‐resistant bacteria. However, there are few published data on the use of tigecycline in paediatric patients. By examining the results of tigecycline use in children, we aimed to draw attention to the fact that tigecycline may be an alternative in the treatment of resistant infections in children.
Technical Violations and Their Effects on Pretrial/Bond Supervision Outcomes

The use of pretrial and bond supervision commonly referred to as supervised release has increased over the last several decades due to burgeoning jail and prison populations. Much research has been conducted on these release mechanisms but has yet to examine the effects of types of technical violations on pretrial failure. The current study examined the effects of technical violations committed by individuals under a felony “bond” supervision program, which included both pretrial releasees and individuals being supervised on bond awaiting a probation revocation hearing, in a large metropolitan area. The results demonstrate while technical violations are associated with pretrial failure, the effects vary by violation type. Furthermore, the findings illustrate differences in risk factors for technical violations while on pretrial/bond supervision. Relevant policy implications of the research are provided.
Altered prerequisites: A cross-sectional survey regarding cancer care in Sweden during COVID-19 from the viewpoint of contact nurses in cancer care

Contact nurses in cancer care were vital in sustaining cancer care in Sweden during the COVID-19 pandemic. The aim of this study was to investigate their experiences of providing care to people with cancer in these exceptional circumstances to identify emerging challenges and opportunities that must be addressed moving forward. A survey distributed to contact nurses was supplemented with questions regarding the pandemic. The study design was a cross-sectional survey, analyzed with descriptive statistics and content analysis, reported in accordance with STROBE. Almost half of respondents (n = 337) reported not being able to provide the same support as before the pandemic. Analysis of open-ended question responses (n = 232) revealed a main theme: Altered prerequisites for providing care. Three categories related to altered interaction, accessibility, and nursing reality were revealed. Thorough reflection is needed to make use of lessons learned and avoid sustaining the short-term solutions needed to cope with the acute phase of the pandemic.
Effects of Internet-Based Nutrition and Exercise Interventions on the Prevention and Treatment of Sarcopenia in the Elderly

Effective nutrition and exercise interventions may improve sarcopenia in the elderly. The purpose of our study was to investigate the effectiveness of Internet-based nutrition and exercise interventions in the elderly with sarcopenia. Participants were divided into 4 groups: control, nutrition, exercise, and comprehensive (nutrition plus exercise) groups; there was at least 50 participants in each group. Our trial lasted 12 weeks. We conducted dietary and exercise interventions through an app and collected feedback from the participants every three weeks. Information on the diet, skeletal muscle mass, and muscle function was collected before and after the interventions. The comprehensive group had higher high-quality protein intake than the control (p = 0.017) and exercise (p = 0.012) groups. After the interventions, we obtained differences in skeletal muscle mass, skeletal muscle mass/height2, skeletal muscle mass/weight, muscle mass/BMI, and skeletal muscle mass/body fat percentage (p < 0.05). Changes in average daily energy and total daily protein intakes were not significantly different; however, there was an overall improvement in the intervention groups relative to baseline data. There were no changes in the average daily time of moderate physical activity. The Internet was an effective tool of nutrition intervention in the elderly with sarcopenia. The Internet-based nutrition intervention improved high-quality protein intake and skeletal muscle mass in the elderly with sarcopenia.
Outage probability of non-orthogonal multiple access schemes with partial relay selection

In this paper, the outage performance of nonorthogonal multiple access (NOMA) schemes in amplify-and-forward (AF) relay systems with partial relay selection is investigated. To this end, closed-form expressions for the outage probabilities at two users are derived, based on which an asymptotic analysis at high signal-to-noise ratio (SNR) is carried out to provide additional insights into the system performance. In particular, the diversity order at each user is explicitly obtained. Numerical results illustrate the impact of relay selection on the performance of the considered NOMA scheme. Also, computer simulation results are presented to validate the accuracy of the attained analytical results.
COVID-19 – a boundary crossing event for teacher educators

ABSTRACT Considering COVID-19 as a boundary-crossing event, the study sought to bring forward the voices of teacher educators (TEs) in Israel as boundary-crossers. It focused on their sense of self-efficacy, professional learning, and professional identities in COVID-19 circumstances. The results of this nationwide quantitative research (N = 385) revealed that TEs were highly satisfied with their professional performance. Their sense of self-efficacy was highest about their ability to teach the content knowledge effectively. Yet, they rated lower their ability to integrate digital tools effectively in their teaching and provide social and emotional support to their students. It was also found that informal (individual self-study) and nonformal (social and collaborative) types of professional learning positively impacted and engaged the TEs. Institutional formal learning was ranked last. Finally, a change in professional self-identification emerged only in a small group of TEs who identified themselves more strongly as mentors, educational entrepreneurs, and curriculum developers over the COVID-19 events than before.
Is There a Difference in Fear-Avoidance, Beliefs, Anxiety and Depression Between Post-Surgery and Non-Surgical Persistent Spinal Pain Syndrome Patients?

Introduction Patients with post-surgery persistent spinal pain syndrome (PSPS) or non-surgical PSPS might be affected by sustained fear-avoidance beliefs (FAB), anxiety and depression. In this scenario, this study aimed to describe those aspects in patients with post-surgery PSPS and non-surgical PSPS. Methods This study included patients with PSPS, and non-surgical PSPS, over 18 years, with quarterly evaluations at the Chronic Pain Clinic. After evaluation, demographic and clinical characteristics were obtained. The Beck Depression Inventory-II, Beck Anxiety Inventory, Douleur neuropathique 4 questions, Visual Analog Pain Scale, and Fear-Avoidance Beliefs Questionnaire–Brazilian Version (FABQ-Brazil) were used to evaluate psychological aspects. Results Forty-six patients were included, 23 patients with post-surgery PSPS and 23 with non-surgical PSPS. Both groups had high scores in the physical and work domains of the FABQ, high rates of absenteeism and most patients in these groups had moderate-to-severe neuropathic pain and some degree of anxiety and/or depression. The groups showed no statistically significant difference (p > 0.05) when comparing all questionnaires. Discussion This is one of the first studies to evaluate FAB and other associated psychological factors, such as anxiety and depression, in patients with post-surgery PSPS in a follow-up several years after surgery and compare with patients diagnosed with non-surgical PSPS. In this study, most patients in both groups had high scores in the FABQ domains, not having statistically relevant difference between groups. Conclusion Even though there was no statistically relevant difference between the PSPS patient with or without surgical history in terms of the assessed outcome measures, the described scores for fear-avoidance beliefs, pain, anxiety and depression were high, showing an interference in the daily life activities of those patients.
Stiffness Characterization of Asphalt Mixtures with High Recycled Material Content and Recycling Agents

Economic and environmental considerations have prompted the use of reclaimed asphalt pavement (RAP) and recycled asphalt shingles (RAS) in asphalt mixtures. However, given the concerns about long-term pavement performance, state departments of transportation (DOTs) tend to limit the quantities of these recycled materials unless certain mixture modifications are made [e.g., use of a softer virgin binder performance grade (PG) and warm-mix asphalt technology, the addition of a recycling agent (RA), or any combination of these modifications]. This study focused on the stiffness characterization of recycled asphalt mixtures with combinations of virgin binder PG, RAP, RAS, and RA. Materials were collected from two field projects in Texas and Indiana, and laboratory specimens were prepared and tested for resilient modulus, and dynamic modulus (|E*|) after short-term oven aging (STOA) and long-term oven aging (LTOA). An RA effectiveness parameter was proposed to quantify the rejuvenating effect of RA, which was defined as the percentage reduction in mixture stiffness for the recycled mixture with RA versus the corresponding control mixture without RA. Furthermore, the |E*| test results were analyzed with a Black Space diagram to discriminate asphalt mixtures with different stiffness and relaxation characteristics. The test results indicated that the incorporation of RA was effective in reducing the stiffness of asphalt mixtures with high recycled material content, but the effectiveness diminished with aging. Moreover, recycled mixtures with a softer and less brittle virgin binder and an RA at a higher dosage showed desirable stiffness and relaxation properties after STOA and LTOA.
TESS light curves of cataclysmic variables – I – Unknown periods in long-known stars

Cataclysmic variables (CVs) exhibit a plethora of variable phenomena many of which require long, uninterrupted light curves to reveal themselves in detail. The month long datasets provided by TESS are well suited for this purpose. TESS has the additional advantage to have observed a huge number of stars, among them many CVs. Here, a search for periodic variations in a sample of CVs of the novalike and old novae subtypes is presented. In 10 of the 15 targets either previously unseen positive or negative superhumps or unusual features in known superhumps are identified. The TESS light curves demonstrate that the occurrence of superhumps in these types of CVs is not an exception but quite common. For 8 systems new or improved values for the orbital period are measured. In TV Col the long-sought optical manifestation of the white dwarf spin period is first seen in form of its orbital sideband. The mystery of multiple photometric periods observed in CP Pup in the past is explained by irregularly occurring anomalous states which are reflected in the light curve.
The role of care-seeking behavior and patient communication pattern in online health information-seeking behavior - a cross-sectional survey

Introduction online health information-seeking behaviour has been on the increase and patients are seeking more responsibility in decisions about their health. Previous studies have mostly predicted online health information-seeking behaviour with demographic characteristics and not current behaviours driven by improving online information. The study attempts to bridge the gap between fast-developing patient online health information-seeking behaviour and health behaviour research. Methods a cross-sectional survey was conducted in the Ghanaian city of Accra. Descriptive statistical analysis was used to reveal frequencies and range of scores on measurement scales. All measurement scales used in the study were tested for reliability. Univariate analysis was used to find correlations and key properties of the dependent and independent variables. Multivariate analysis was used to test hypotheses. Results one hundred and eighteen (118) adults were surveyed. Cronbach alpha reliabilities of measurement scales ranged from . 71 to . 91. The hypothesis that care seeking behaviour and patient communication pattern predict online health information seeking behaviour, was supported (r = .45, standard error = 5.84) by a multiple linear regression. Conclusion patients are engaged in online health information seeking because they want to be more active in decisions about their health. Findings further suggest that patients rely on online information to direct communications with their caregivers.
Macular and Optic Disc Parameters in Children with Amblyopic and Nonamblyopic Eyes under Optical Coherence Tomography Fundus Images

The aim of this study was to investigate the characteristics of macular and optic disc parameters in children with amblyopic and nonamblyopic eyes, using fundus images under optical coherence tomography (OCT). 36 patients with anisometropic amblyopia were selected in the experimental group, and another 36 healthy volunteers were selected in the control group, OCT examinations were performed in all groups, and the mean diopter, mean corrected visual acuity (CVA), mean axial length, mean optic disc retinal nerve fiber layer (RNFL) thickness, and mean macular fovea thickness were recorded in the two groups. The results found that the average diopter of the patients in the control group and the experimental group was +2.30 ± 2.54 D and +5.51 ± 1.76 D, respectively. The average CVA was 0.86 ± 0.07 and 0.22 ± 0.16, respectively; the average eye axial length was 22.41 ± 1.20 mm and 21.11 ± 0.78 mm, respectively. As P < 0.05, the differences were statistically significant in the three indicators between the two groups. There was no significant difference between the two groups in the average thickness of the RNFL of the optic disc and the average thickness of the central fovea of macula (P > 0.05). There was some correlation among CVA, diopter, eye axial length, RNFL thickness, and average thickness of macular fovea, but the correlation was not significant. It was suggested that there were certain differences in the macular and optic disc parameters between amblyopic and nonamblyopic children, but the difference is little. Thereout, a certain objective basis was provided for the early detection and treatment of amblyopia.
Acrylic acid conformers and their interactions with dibutyl ether

Abstract Fourier Transform Infrared spectra of pure acrylic acid (ARA), dibutyl ether, and their binary solutions at various acid concentrations have been recorded. Density functional theory calculations on ARA monomers and dimers have been carried out. In addition to the cis–cis and trans–trans dimers, cis–trans dimers also exist in liquid acid. The dimer ring formed by carboxyl group has an asymmetry. The experimental asymmetric and symmetric hydroxyl and carbonyl stretching bands have been assigned. Shifts suffered by the absorption bands in binary solutions have been analyzed in view of the formation of heteromolecular hydrogen bonds.
