Impact of Self-Energy Recycling and Cooperative Jamming on SWIPT-Based FD Relay Networks with Secrecy Constraints

This paper investigates the secrecy performance of a power splitting-based simultaneous wireless information and power transfer cooperative relay network in the presence of an eavesdropper. The relay is considered to operate in full-duplex (FD) mode to perform both energy harvesting and information decoding simultaneously. To accomplish that, the relay is assumed to employ two rechargeable batteries, which switch between power supplying mode and charging mode at each transmission block. We also assume that the self-interference inherent of the FD mode is not completely suppressed. Therefore, it is assumed that, after some stages of passive and active self-interference cancellation, there is still a residual self-interference (RSI). A portion of this RSI (remaining after passive cancellation) is recycled for energy harvesting. In order to improve the system secrecy performance, it is considered that the relay can split its transmit power to send the information signal and to emit a jamming signal to degrade the eavesdropper’s channel. The secrecy performance is evaluated in terms of the secrecy outage probability and the optimal secrecy throughput. Tight-approximate and asymptotic expressions are obtained for the secrecy outage probability, and the particle swarm optimization method is employed for addressing the secrecy throughput optimization problem. From numerical results, we show that the secrecy performance can be increased depending on the self-energy recycling channel condition. Finally, our derived expressions are validated via Monte Carlo simulations.
Preparation and Characterization of Sodium Alginate-Based Edible Film with Antibacterial Additive using Lemongrass Oil

Sodium alginate films at various concentrations of glycerol (0.4, 0.6, and 0.8% v/v) were prepared and characterized. The thickness, water solubility (WS), water vapor transmission rate (WVTR), tensile strength (TS), elongation at break (EB) and Young’s Modulus (YM) of the films were affected by the amount of glycerol added. Among these films, the film containing lower glycerol (0.4 % v/v) presents better WS, WVTR, and the highest TS compared to other concentrations. Sodium alginate films containing lemongrass essential oil (LEO) were prepared to examine its antibacterial properties on four common foodborne pathogens: B. subtilis, S. aureus, E. coli, and P. aeruginosa using Disc-diffusion assay. The highest inhibition was shown by E. coli (21 mm/susceptible), B. subtilis (18 mm/intermediate), S. aureus (16 mm/intermediate), and P. aeruginosa (13.5 mm/resistant). The incorporation of lemongrass essential oil as a natural antibacterial agent in the film formulation has developed its potential to be used as an active packaging with improved physical properties, especially water barrier properties.
Transcription Analysis for Core Networks of lncRNAs–mRNAs: Implication for Potential Role in Sterility of Crassostrea gigas

Simple Summary This study reveals the expression profiles of lncRNA in the gonads of the Pacific oyster Crassostrea gigas. The potential function of lncRNAs was predicted in the case of antisense and cis-regulatory mechanisms based on their physical positions and their coexpression relationships in the case of trans regulation. Sterility-related DEGs and DELs were chosen for subsequent analysis, demonstrating that trans-regulatory lncRNAs might play a vital role in the gametogenesis of C. gigas. We constructed core networks of lncRNAs–mRNAs for triploid sterile females and hermaphrodites based on pathway results, in which 28 lncRNAs and their 54 trans-regulatory genes were detected. Among 28 sterility-specific lncRNAs, MSTRG.79882. 3 and MSTRG.79882. 4 for triploid sterile females and MSTRG.33704. 1, MSTRG.63844. 1, and MSTRG.5675. 1 for hermaphrodites play the most significant role. Abstract Long noncoding RNA (lncRNA), a type of non-protein-coding transcript, is emerging as a crucial regulator of gene expression. However, few roles of lncRNA in the reproductive process of the Pacific oyster (Crassostrea gigas) have been defined, especially in the regulatory mechanism of sterile triploids gametogenesis. To uncover the potential role of lncRNA, the gonads of diploids, sterile triploids, and partially sterile triploids underwent RNA sequencing. A total of 9618 reliable lncRNAs were identified. The target relationship between lncRNA and mRNA was predicted based on cis, trans, and antisense regulation with bioinformatic software. We chose differentially expressed lncRNAs and mRNAs when sterile triploids were compared to partially sterile triploids and diploids for subsequent functional enrichment analysis. Findings revealed that trans-regulatory lncRNAs might play a significant role in the gametogenesis of C. gigas. Combining pathway results, we constructed core networks of lncRNAs–mRNAs for triploid sterile females and hermaphrodites. Fifty-four genes related to cell division, germline-cell maintenance, and glycogen metabolism were found to be associated with sterility. A total of 28 candidate lncRNAs were predicted to trans-regulate these genes. We speculated that MSTRG.79882. 3 and MSTRG.79882. 4 for triploid sterile females and MSTRG.33704. 1, MSTRG.63844. 1, and MSTRG.5675. 1 for hermaphrodites were highly important as they were predicted to regulate more sterility-specific genes than others. Our work collectively identified sterility-related lncRNAs and implicated the potential mechanism of lncRNA-mediated regulation in the gametogenesis of sterile triploid oysters.
Genomic landscape and prognosis of patients with TP53-mutated non-small cell lung cancer

Background The TP53 tumor suppressor gene plays an important role in preventing and inhibiting the growth of tumor by regulating cell cycle, apoptosis and DNA repair. Meanwhile, the TP53 gene is one of the most frequently altered gene in non-small cell lung cancer (NSCLC) patients. Mutant TP53 (TP53-MUT) may lose tumor suppressor activity and gain tumor promoting functions, which play an important role in cancer risk, therapy resistance and poor prognosis. The impact of TP53-MUT on the prognosis of NSCLC patients need to be further studied. Methods We obtained genomic and clinical data from The Cancer Genome Atlas (TCGA). Mutation profiles, the TMB, disease-free survival (DFS), and overall survival (OS) were compared between patients with different TP53-MUT statuses. Results TP53-MUTs were detected in 46.6% of patients with lung adenocarcinoma (LUAD) (264 of 566) and 82.3% of those with lung squamous cell carcinoma (LUSC) (401 of 487). The most frequently co-mutated genes in patients with LUAD carrying a TP53-MUT included classic driver genes such as epidermal growth factor receptor (EGFR) and anaplastic large-cell lymphoma kinase (ALK), while Kirsten rat sarcoma viral oncogene (KRAS) mutations and TP53-MUTs appear to be mutually exclusive. This mutual exclusivity was not observed in patients with LUSC, in whom titin (TTN) and CUB and Sushi multiple domains 3 (CSMD3) were the most frequently co-mutated genes. A higher TMB was significantly associated with TP53-MUTs in patients with LUAD but not in those with LUSC. In patients with stage I-III NSCLC who had undergone surgery, there was no significant difference in DFS between patients carrying TP53-wildtype (TP53-WT) and TP53-MUTs, irrespective of histology or mutation type. However, the presence of TP53-MUT was associated with shorter OS in patients with LUAD (49 vs. 54 months, respectively; P=0.13) and significantly longer OS in those with LUSC (62 vs. 29 months, respectively; P=0.015). Conclusions In contrast to most previous studies, we revealed TP53-MUT characteristic in NSCLC patients according to histology-specific differences and the association between TP53-MUT and the mutation landscape, the TMB, and the OS. These findings suggest a need for individualized management for patients with LUAD and LUSC who carry a TP53-MUT, and warrant further research.
Assessing the User Experience of Consumer Haptic Devices for Simulation-based Virtual Reality

Although technological advancements brought us increasingly realistic virtual experiences, Virtual Reality (VR) still basically relies on high visual and audio fidelity only. Indeed, haptic devices that could help to digitally recreate a further sense have been subject of investigations for a long time, but it is only recently that they took their first steps in the consumer domain. Within the definition of haptic feedback, various kinds of stimuli can be identified, though entry-level haptic devices usually supports just a subset of them. In order to cope with this limitation, less capable haptic devices may be combined with alternative approaches for providing haptic stimuli, compensating possible lacks through configurations that are affordable than fully-fledged products. This work investigates the performance, in terms of User eXperience (UX), of two haptic solutions based on consumer devices: a VR glove endowed with both vibrational and force-feedback, and a VR haptic glove provided with vibrational feedback paired with a passive haptic-based mock-up. The two configurations are compared by means of a user study against a relevant scenario in the context of a simulation-based VR experience encompassing the use of an electromechanical tool.
Endophytic fungus Bipolaris sp. CSL-1 induces salt tolerance in Glycine max.L via modulating its endogenous hormones, antioxidative system and gene expression

ABSTRACT Salinity stress is one of the most serious environmental stress that inhibits plant growth. In this study, we adopted an environment friendly technique and screened different plant growth-promoting fungi for different plant growth promoting (PGP) traits and salinity stress. Among those isolates, Bipolaris sp. CSL-1 was selected based on plant growth-promoting characteristics, such as producing indole-3-acetic acid (IAA), gibberellins (GAs), organic acids and resistance to sodium chloride (NaCl) stress. Here, we found that inoculating soybean with isolate CSL-1 significantly increased shoot and root length, shoot and root fresh and dry weight and chlorophyll content under NaCl stress (200 mM). Endogenous abscisic acid (ABA) levels were significantly decreased, whereas salicylic acid (SA) levels were increased in CSL-1-inoculated plants under NaCl stress. NaCl-treated noninoculated plants showed higher levels of antioxidants and oxidative stress such as peroxidase, polyphenol oxidase (PPO), malondialdehyde (MDA) and superoxide anion (SOA). Furthermore, CSL-1 inoculation improved soybean resistance to NaCl stress, and there was a significant decrease in GmFDL19, GmNARK, and GmSIN1 expression levels. As a result, the fungal isolate CSL-1 mitigates the effect of salt stress and enhance soybean growth and might be used as a valuable ecofriendly microorganism resource in salt-affected areas.
Assessment of Turkey Farming Management Practices by Small-Scale Rural Farmers in Eastern Nigeria

A survey of rural turkey farmers was conducted in three villages in the Eastern part of Nigeria, namely: Amukwa, Amaeze and Nguru. The aim of the study was to assess the prevailing management and production practices of turkey farmers in the area. Information obtained included flock size, reasons for keeping birds, breeding and management practices among others. The multi-stage random sampling method was used to collect information from 180 respondents. Results obtained revealed variability in response among flock sizes (1–20), with most (90%) respondents being part-time farmers. Mean scores, in terms of the level of adoption of standard management practices by turkey farmers, were given as cleaning and disinfection of pen before restocking ( x= 4.60), removal of droppings (x = 4.57), and changing and replacement of litters ( x= 4.4). Beak trimming ( x= 1.27) was the lowest-ranked farm practice by farmers. It was concluded that the management practices and production of turkey in the study area are below standard when compared to those in developed societies. Adequate support for farmers in terms of finance and regular training, among others, by relevant agencies including the government may help improve the production of turkey in the area.
Metabolic Contribution and Cerebral Blood Flow Regulation by Astrocytes in the Neurovascular Unit

The neurovascular unit (NVU) is a conceptual framework that has been proposed to better explain the relationships between the neural cells and blood vessels in the human brain, focused mainly on the brain gray matter. The major components of the NVU are the neurons, astrocytes (astroglia), microvessels, pericytes, and microglia. In addition, we believe that oligodendrocytes should also be included as an indispensable component of the NVU in the white matter. Of all these components, astrocytes in particular have attracted the interest of researchers because of their unique anatomical location; these cells are interposed between the neurons and the microvessels of the brain. Their location suggests that astrocytes might regulate the cerebral blood flow (CBF) in response to neuronal activity, so as to ensure an adequate supply of glucose and oxygen to meet the metabolic demands of the neurons. In fact, the adult human brain, which accounts for only 2% of the entire body weight, consumes approximately 20–25% of the total amount of glucose and oxygen consumed by the whole body. The brain needs a continuous supply of these essential energy sources through the CBF, because there are practically no stores of glucose or oxygen in the brain; both acute and chronic cessation of CBF can adversely affect brain functions. In addition, another important putative function of the NVU is the elimination of heat and waste materials produced by neuronal activity. Recent evidence suggests that astrocytes play pivotal roles not only in supplying glucose, but also fatty acids and amino acids to neurons. Loss of astrocytic support can be expected to lead to malfunction of the NVU as a whole, which underlies numerous neurological disorders. In this review, we shall focus on historical and recent findings with regard to the metabolic contributions of astrocytes in the NVU.
Psycho-Behavioural Changes in Dogs Treated with Corticosteroids: A Clinical Behaviour Perspective

Simple Summary Corticosteroids hormones are central to stress responses and, along with other hormones and neurotransmitters, contribute to the onset of physiological and behavioural changes aimed at helping the animal cope with anticipated demand. Both the human and animal literature suggest that exposure to systemic exogenous corticosteroid treatments can be associated with negative emotional states. In this paper, the potential behavioural effects of exogenous corticosteroid treatment on dogs and other species are discussed to show why consideration should be given to this matter when prescribing these drugs. Abstract Arousal and distress are often important factors in problematic behaviours, and endogenous corticosteroids are important mediators in the associated stress responses. Exogenous corticosteroid treatments have been reported to change behaviour in human patients and laboratory animals, with similar changes also noted in pet dogs. These behaviours not only potentially adversely impact the welfare of the dogs, but also the quality of life of their owners. Indeed, corticosteroids can bias sensitivity towards aversion in dogs. A decrease in behaviours associated with positive affective states, such as play and exploratory behaviours, together with an increase in aggression and barking have also been described in dogs. According to the available literature, human patients with pre-existing psychiatric disorders are more at risk of developing behavioural side effects due to corticosteroid treatments. It is reasonable to consider that the same may happen in dogs with pre-existing behavioural problems. In this paper, the possible behavioural side effects of exogenous corticosteroids are summarised to help inform and support veterinarians prescribing these drugs.
Structure design and experimental analysis of a perforated dielectric elastomer sound absorber

A large part of research on membrane mufflers focuses on the sound insulation performance of the membrane, and there is less research on the sound absorption performance of the membrane. In most cases, membrane mufflers only have some narrow absorption peaks in the low frequency band. In this paper, a micro-perforated dielectric elastomer membrane sound absorber is introduced to broaden the sound absorption frequency band of the membrane in the low frequency band. Different initial thickness, perforation aperture, and perforation spacing of the dielectric elastomer membranes were designed and fabricated, and the effect of the variation of the parameters was investigated by testing the sound absorption performance of the structural specimens. It was found that increasing the initial thickness of the membrane, appropriately decreasing the perforation aperture, and appropriately controlling the perforation spacing could improve the sound absorption performance of the structure. And based on the perforated membrane, a ring electrode structure was further designed to realize the electrically adjustable sound absorption frequency of the membrane. After the membrane with the ring electrode structure was perforated in the central region, the sound absorption band of the membrane was broadened significantly, and the applied voltage could realize the electrically adjustable sound absorption performance of the structure in the low frequency band.
Getting Better or Getting Worse? A Population-Based Study on Trends in Self-Rated Health among Single Mothers in Germany between 1994 and 2018

Background: While numerous studies suggest that single motherhood is associated with socioeconomic disadvantages and poor health, few studies have analyzed how these conditions have evolved over time. Addressing this gap, we examined the temporal development of self-rated health (SRH) among single compared to partnered mothers, and the role of socioeconomic factors that may have influenced this trend. Methods: We used representative longitudinal data from the German Socioeconomic Panel Survey (G-SOEP) between 1994 and 2018, consisting of 83,843 women with children, aged 30–49 years (13,664 single and 70,179 partnered mothers). Time trends in SRH and socioeconomic factors were analyzed by means of logistic regression analyses. We applied the Karlson–Holm–Breen (KHB) method for decomposing the total time effect into direct and indirect parts via socioeconomic mediators. Results: The predicted probabilities of good SRH decreased in single mothers from 57.0% to 48.4%, while they increased in partnered mothers from 54.8% to 61.3%. Similarly, predicted probabilities of poor SRH rose from 15.0% to 22.7% in single mothers while decreasing slightly from 12.0% to 11.4% in partnered mothers. Moreover, socioeconomic factors worsened over time for single mothers, while they mostly improved for partnered mothers. Decomposing the time trend revealed that the deterioration of single mothers’ health was partly explained by the worsening of socioeconomic disadvantages, of which the decline in full-time employment, the rise in low incomes, and in unemployment contributed most. Conclusions: The alarming rise in socioeconomic and health disadvantages among single mothers in Germany shows that action is needed to counter this trend.
Promoting Mental Health and Wellbeing in Multicultural Australia: A Collaborative Regional Approach

Migrant communities are often under-served by mental health services. Lack of community engagement results in missed opportunities for mental health promotion and early intervention, delayed care, and high rates of untreated psychological distress. Bilingual clinicians and others who work with these communities lack linguistically and culturally appropriate resources. This article reports on the implementation and evaluation of a community-based group mindfulness program delivered to Arabic and Bangla-speaking communities in Sydney, Australia, including modifications made to the content and format in response to the COVID-19 pandemic. The program was positioned within a stepped-care model for primary mental health care and adopted a collaborative regional approach. In addition to improved mental health outcomes for face-to-face and online program participants, we have documented numerous referrals to specialist services and extensive diffusion of mindfulness skills, mostly to family members, within each community. Community partnerships were critical to community engagement. Training workshops to build the skills of the bilingual health and community workforce increased the program’s reach. In immigrant nations such as Australia, mainstream mental health promotion must be complemented by activities that target specific population groups. Scaled up, and with appropriate adaptation, the group mindfulness program offers a low-intensity in-language intervention for under-served communities.
STUDENTS’ LOYALTY: DOES VALUE CO-CREATION IN HIGHER EDUCATION INSTITUTIONS MATTER?

This study investigates the influence for intrinsic and extrinsic motives on customers` participation in value co-creation activities (CPVCA), beside examining the direct and indirect impact for CPVCA on customers` loyalty. Quantitative research approach is used, while the study population encompasses all Lebanese private universities students. A questionnaire was developed to gather data from 403 universities` students who were chosen using the convenience sampling technique. PLS-SEM was adopted to examine the study proposed scale validity and the relationships between its latent variables. The current study results indicate a positive influence for both intrinsic and extrinsic motives on CPVCA. Also, the findings reveal a significant direct relationship among CPVCA and customer loyalty, as well as an indirect relationship via mediating brand experience.
Synthesis, Cyclization and Nucleophilic Substitution Reactions of Substituted Pyrazole Carboxylic Acid

Substituted pyrazole carboxylic acid 2a-b derivatives, obtained from 2,3-furandione 1 and benzaldehyde hydrazone 11a-b was converted via reactions of its acid chloride 3a-b. The corresponding ester 6a-b, urea 7a-b, and amide derivatives 4a-b, 8a-b were obtained from the reaction of the acyl chloride of the pyrazole carboxylic acid with various alcohols, urea, and amines. Additionally, the corresponding nitrile derivatives 5 were obtained by extracting water from the amide derivatives (SOCl2 / DMF). Furthermore, cyclization reactions of substituted pyrazole carboxylic acid derivatives using hydrazine were investigated 9 and reaction of 2b decarboxylation product 10.
