Published: December 2023

Aims: Consumptive behavior has become familiar to students because of the support of an increasingly modern era and the ease of buying needs or wants. This study aims to determine whether financial Literacy, electronic Money, Lifestyle, and self-control significantly affect consumer behavior, especially among students.
Study Design: Active FEB students in DKI Jakarta Province, Central Java, Special Region of Yogyakarta
Place and Duration of Study: at Universitas Negeri Jakarta, Universitas Muhammadiyah Purwokerto, Universitas Wijayakusuma Purwokerto, Universitas Diponegoro, Universitas Tidar, Universitas Gajah Mada and Universitas UPN Yogyakarta, which have a total of 18.255 students. The sample for this study is 160 respondents that was determined using the Slovin technique.
Methodology: In this research, the methods used to analyze data are using a Partial Least Square (PLS) based structural equation model (SEM). By using SmartPLS 3.0, each hypothesis will be tested to understand the relationships between variables. To test Validity and reliability, the research uses an outer model. Hypothesis testing was done using inner models.
Results: Financial Literacy had no significant effect on consumptive behavior. Electronic 0money has no significant impact on consumptive behavior. Lifestyle significantly affects consumptive behavior with Original Sample 0,449. Self-control significantly affects consumptive behavior with Original Sample 0,187.
Conclusion: Financial Literacy and electronic Money do not ultimately influence students' consumptive behavior; this could happen because students do not use their financial understanding in everyday life, and the ease of electronic money does not affect students' consumptive behavior. At the same time, Lifestyle and self-control influence student consumption behavior. Uncontrolled Lifestyle and self-control make students consumptive in everyday life.

ImportancePregnancy weight gain may affect the association of bariatric surgery with postsurgery pregnancy outcomes. However, the association of pregnancy weight gain with bariatric surgery is unclear.ObjectiveTo compare pregnancy weight gain among women with a history of bariatric surgery vs those without and to investigate whether pregnancy weight gain differs by surgical procedure, surgery-to-conception interval, and/or surgery-to-conception weight loss.Design, Setting, and ParticipantsThis nationwide, population-based matched cohort study was conducted in Sweden from 2014 to 2021. Singleton pregnancies with a history of bariatric surgery were propensity score matched (1:1) to pregnancies without such a history according to early-pregnancy body mass index (BMI), prepregnancy diabetes, prepregnancy hypertension, maternal age, smoking status, education level, height, country of birth, and delivery year. In addition, post–gastric bypass pregnancies were matched to post–sleeve gastrectomy pregnancies using the same matching strategy. Data analysis was performed from November 2022 to May 2023.ExposureHistory of bariatric surgery.Main Outcomes and MeasuresPregnancy weight gain was standardized by gestational age into early-pregnancy BMI-specific z scores.ResultsThis study included 12 776 pregnancies, of which 6388 had a history of bariatric surgery and 6388 were matched controls. The mean (SD) age was 31.6 (4.9) years for the surgery group and 31.4 (5.2) for the matched controls, with an early-pregnancy mean (SD) BMI of 29.4 (5.2) in both groups. Across all early-pregnancy BMI strata, women with a history of bariatric surgery had lower pregnancy weight gain than matched controls. The differences in pregnancy weight gain z score values between the 2 groups were −0.33 (95% CI, −0.43 to −0.23) for normal weight, −0.33 (95% CI, −0.40 to −0.27) for overweight, −0.21 (95% CI, −0.29 to −0.13) for obese class I, −0.16 (95% CI, −0.29 to −0.03) for obese class II, and −0.08 (95% CI, −0.28 to 0.13) for obese class III. Pregnancy weight gain did not differ by surgical procedure. A shorter surgery-to-conception interval (particularly within 1 year) or lower surgery-to-conception weight loss was associated with lower pregnancy weight gain.Conclusions and RelevanceIn this nationwide matched cohort study, women with a history of bariatric surgery had lower pregnancy weight gain than matched controls with similar early-pregnancy characteristics. Pregnancy weight gain was lower in those with a shorter surgery-to-conception interval or lower surgery-to-conception weight loss, but did not differ by surgical procedure.

Published: December 2023

AbstractThe development of all‐solid‐state lithium‐metal batteries (ASSLMBs) is impeded by low coulomb efficiency, short lifetime, poor rate performance, and other problems caused by the rapid growth of lithium (Li) dendrites. Herein, a multiple‐diffusion‐channel N,S‐doped soft carbon with expanded layer spacing is designed/developed by thiourea calcination for dendrite‐free anodes. Since the enlarged layer spacing can improve Li+ transportation rate within the layers and N,S‐doping can facilitate Li+ transport between the layers, the bulk phase diffusion (not just surface diffusion) kinetics can be improved, which in turn reduces the local current density, inhibits the growth of Li dendrites, and improves the rate performance. The resulting ASSLMB achieves record‐high current density (15 mA cm−2), areal capacity (20 mAh cm−2), energy density (403 Wh kg−1), and ultra‐long cycle life (13 000 cycles). >305 Wh kg−1 pouch cells are realized, representing one of the most critical breakthroughs for real‐world application of ASSLMBs.

Published: December 2023

AbstractBiosensors based on graphene and bio‐graphene interfaces have gained momentum in recent years due to graphene's outstanding electronic and mechanical properties. By introducing the patterning of a single‐layer graphene surface by two‐photon oxidation (2PO), the surface hydrophobicity/hydrophilicity and doping can be varied at the nanoscale while preserving the carbon network, thus opening possibilities to design new devices. In this study, the effect of 2PO on the catalytic activity of the noncovalently immobilized enzyme horseradish peroxidase (HRP) on single‐layer graphene‐coated Si/SiO2 chips is presented. To monitor the activity continuously, a simple well‐plate setup is introduced. Upon controllable 1–2‐layer immobilization, the catalytic activity decreases to a maximum value of 7.5% of the free enzyme. Interestingly, the activity decreases with increasing 2PO area on the samples. Hence, the HRP catalytic activity on the graphene surface is locally controlled. This approach can enable the development of graphene‐bio interfaces with locally varying enzyme activity.

Published: December 2023

AbstractAn organocatalytic route has been developed for the isomerization of exo‐vinylene carbonates (exo‐VCs) to endo‐vinylene carbonates (endo‐VCs). The exo‐VC starting material can easily be obtained from propargylic alcohols via cyclization with carbon dioxide. In this study, these exo‐VCs are shown to isomerize to the thermodynamically more stable endo‐VCs in the presence of an N‐heterocyclic base and phenol. Density functional theory (DFT) studies were conducted to elucidate the mechanism, tackling difficulties of the description of charge separation steps. This isomerization process delivers an ample diversity of endo‐VCs in good to excellent yields and chemoselectivities under mild reaction conditions.

AbstractPica, the urge to consume items generally not considered food, such as dirt, raw starch, and ice, are particularly common among pregnant women. However, the biology of pica in pregnancy is not well understood. Therefore, this study aimed to assess how pica relates to endocrine stress and immune biomarkers in a cohort of pregnant Latina women in Southern California. Thirty‐four women completed a structured pica questionnaire. Maternal urinary cortisol and plasma cytokine levels were measured between 21 and 31 weeks' gestation. Associations between pica during pregnancy and biomarkers were assessed using linear regression models adjusting for gestational age. Twelve (35.3%) of the pregnant women reported pica (geophagy and amylophagy) during pregnancy. In multivariate models, those who engaged in pica had higher levels of cortisol (β: 0.37, 95% CI: 0.01, 0.073) and lower levels of IL‐1β (β: −0.06, 95% CI: −0.11, −0.02), IL‐8 (β: −0.30, 95% CI: −0.56, −0.05), IL‐21 (β: −0.35, 95% CI: −0.63, −0.08), and type‐1 inflammation composite (β: −0.29, 95% CI: −0.44, −0.14) than women who did not engage in pica. These results suggest that biological stress and immune response differ for women with pica compared to those without. This study suggests novel physiological covariates of pica during pregnancy. Further research is needed to better understand the mechanisms and temporality underlying the observed associations between pica and endocrine and immune biomarkers.

AbstractCongenital malformations, conditions, injuries, and illness can lead to long‐term physical impairment and disability in nonhuman primates. How individual primates change their behaviors flexibly to compensate for their disabilities can inform our understanding of their resilience and ability to adjust to environmental change. Here, we synthesize the literature on nonhuman primates and disability, addressing the questions: how does disability influence behavior in primates? What insights can we take from the literature to better understand and predict the capacity of primates to modify their behaviors in the face of human‐induced environmental change? We conducted a systematic review of the literature on spontaneous physical impairment and disability in captive, free‐ranging, and wild primates. We surveyed 2807 articles on Web of Science and Scopus and identified 114 studies that fit our predetermined inclusion criteria. Behavioral plasticity, maternal and conspecific care, and the potential for innovation of novel behaviors allow many primates with disabilities to compensate when faced with challenges that are outside the scope of usual circumstances. We also found that 60% of the publications connected primate physical impairment and disability to human activities, suggesting an entangled relationship among humans, the environment, and primate disability. Disability and physical impairments provide an opportunity to examine how primates modify their behavior when presented with challenging conditions, and their potential resilience to a changing environment.

Published: December 2023

AbstractTraditional polarization converters suffer from drawbacks such as significant thickness and high losses, which limit their practical applications. This study introduces a novel metamaterial structure that combines electromagnetically induced transparency (EIT) with linear polarization conversion to overcome these limitations. By harnessing the properties of EIT, this structure achieves low‐loss polarization conversion. The mechanism behind this is the generation of an EIT effect through the coupling of the light and dark modes. Additionally, this study focuses on introducing a slight vertical polarization symmetry disruption and inducing the excitation of small components within the dipole of the EIT structure to achieve close‐to‐complete cross‐polarization conversion. The effect of asymmetry on the polarization conversion rate is also explored. This study offers an innovative approach to designing low‐loss polarization converters utilizing EIT technology.
A molecular dynamics study of 3C‐SiC/epoxy nanocomposite as a metal‐free friction material
Authors: Zhang Yizhan , Yi Yun‐Bo 
Published: December 2023

AbstractThe tribological, mechanical, and thermal properties of an epoxy crosslinking network incorporated with 3C‐SiC nanoparticles, serving as a metal‐free friction material were investigated by molecular dynamics simulations. The considered models encompass pure epoxy materials with 35%, 50%, 65%, and 80% crosslinking degrees, as well as 3C‐SiC/epoxy composite materials at the same crosslinking levels. Glass transition temperature (Tg) of the eight models was analyzed, and the result shows augmenting crosslinking density and addition of 3C‐SiC nanofillers improve Tg of all models. Fractional free volume of each model was quantified to reflect the features of epoxy materials and influence the properties at the atomic scale. Frictional force, normal force, and coefficient of friction (COF) were calculated to elucidate the tribological performance of the epoxy‐based materials. The introduction of 3C‐SiC nanofillers reduces COF. With nanofillers, higher crosslinking degree brings lower COF except 80% crosslinking degree, while without nanofillers, higher COFs are obtained with 35% and 80% crosslinking degrees. 3C‐SiC/epoxy composite with heightened crosslinking degree demonstrates superior Young's modulus, elevated tensile stress, and relatively smaller strain. Thermal conductivity analysis highlights the positive impact of both increased crosslinking density and incorporation of 3C‐SiC nanofillers on heat transfer. Temperature elevation further enhances thermal conductivity.

Published: December 2023

AbstractThis paper focuses on event‐triggered sampled‐data synchronization of uncertain complex networks with time‐varying coupled delays. First of all, a discrete event‐triggered sampled‐data control scheme is adopted, which not only makes the state of the system be monitored in discrete time, but also the sampling information is effectively transmitted. The proposed event‐triggered mechanism effectively prevents Zeno behavior. In addition, we also use some novel piecewise time‐dependent Lyapunov–Krasovskii and Wirtinger inequality to handle the time‐varying delays and parameter uncertainties of complex networks. Then, synchronization criteria are given for uncertain complex networks. Finally, the simulation results show that the control scheme can significantly reduce the number of transmitted signals while maintaining the uncertain complex networks synchronization.

AbstractFlexible, scalable, and low‐cost energy storage solutions are required for the widespread use of renewable energy and the mitigation of climate change. State‐of‐the‐art lithium‐ion batteries provide high specific energy density; however, designing a safe and cost‐effective grid‐scale lithium‐ion battery is still a major challenge. Redox flow batteries are scalable due to their ability to decouple power and energy; however, the commercial applications of these batteries are limited because of expensive ion‐selective membranes. In this paper, we report a modified battery design approach in which Bi/BiOCl and V4+/V5+ reaction‐based redox couples are utilized while employing a gel‐based architecture. We show, for the first time, that Bi/BiOCl conversion reaction based redox couple can reversibly work against traditional vanadium‐based redox pair in an aqueous electrolyte. Redox active materials in this cell design are in the gel form, and a traditional membrane or a separator is not required. This proof‐of‐concept battery delivers 0.9 V with a volumetric energy density of 22.14 Wh/L.

AbstractBackgroundFoley catheters have been subject to limited development in the last few decades. They fulfil their basic function of draining urine from the bladder but cause other associated problems. T‐Control is a new silicone Foley catheter with an integrated fluid control valve whose design aims to reduce the risks associated with bladder catheterisation by a multifactorial approach. The general purpose of this study is to evaluate the effectiveness and cost‐effectiveness of the T‐Control catheter versus the Foley‐type catheter in patients with Acute Urine Retention (AUR).Study designThis is a pragmatic, open, multicentre, controlled clinical trial with random allocation to the T‐Control catheter or a conventional Foley‐type catheter in patients with AUR.EndpointsThe magnitude of infections will be analysed as a primary endpoint. While as secondary endpoint, the following will be analysed: rate of symptomatic and asymptomatic infections; days free of infection; quality of life‐related to self‐perceived health; indication of associated antibiotic treatments; determination of biofilm; number of catheter‐related adverse events; use of each type of catheterisation's healthcare resources; level of satisfaction and workload of health professionals and acceptability of the T‐Control device as well as the patient experience.Patients and methodsEligible patients are male adults aged ≥50 years, with AUR and with an indication of bladder catheterisation for at least 2 weeks. The estimated sample size is 50 patients. Patient follow‐up includes both the time of catheter insertion and its removal or change 2 weeks later, plus 2 weeks after this time when the patient will be called for an in‐depth interview.

AbstractNucleic acid detection is an important tool for clinical diagnosis. The purification of the sample is the most time‐consuming step in the nucleic acid testing process and will affect the results of the assay. Here, we developed a surface modification‐based nucleic acid purification method and designed an accompanying set of centrifugation equipment and chips to integrate the steps of nucleic acid purification on a single platform. The results of experiments with HeLa cells and HPV type 16 as samples showed that the mentioned method had good nucleic acid purification capability and the accompanying equipment greatly simplified the operation of the experimenters in the whole process. Overall, our equipment can improve the efficiency of nucleic acid purification and is suitable for application in larger‐scale clinical assays.

AbstractThe aim of this research is to empirically investigate the influence of supply chain management practices (SCMPs) on customer satisfaction through the mediating roles of flexibility and technology adoption. A questionnaire was used to collect data from organizational consumers in the Egyptian context, in which hypotheses were analyzed through covariance‐based structural equation modeling for 1009 usable questionnaires. The findings revealed the positive relationship between SCMPs and flexibility, technology adoption, and customer satisfaction. Moreover, it revealed the positive relationship between technology adoption and customer satisfaction, however, the direct impact of flexibility on customer satisfaction is not significant. Empirical evidence also illustrated that technology adoption can significantly mediate the relationship between SCMPs and customer satisfaction.
