Abstract Purpose To determine the impact of low versus atmospheric oxygen tension during only the pre-maturation phase of biphasic capacitation in vitro maturation. Methods The study involved sibling oocytes (532 cumulus-oocyte complexes [COCs] from 20 participants [mean age 29.5 ± 2.5 years]) with polycystic ovary syndrome undergoing CAPA-IVM without gonadotrophins. After oocyte pick-up (OPU), COCs were randomized...

Valorization of kombucha fermentation medium for electricity generation in recirculating microbial fuel cells with Shewanella putrefaciens
Abstract Kombucha is a traditional fermented tea rich in organic acids and shows potential as a carbon source for Shewanella species to generate electricity in microbial fuel cells (MFCs). This research investigated the applicability of kombucha post-fermentation medium as a substrate to support the growth of Shewanella putrefaciens and electricity generation in recirculating MFCs. A preliminary growth study showed...
Understanding social commerce adoption in Vietnam: A synergy of social, technological, and behavioral drivers
Abstract This study investigates the key social, psychological, and technological factors influencing social commerce adoption among Gen Z university students in Vietnam. It examines how social support constructs, trust, and technophilia contribute to forming social commerce intention and translating it into actual usage behavior. Guided by the Stimulus-Organism-Response model and the Theory of Planned Behavior,...
Defect-Controlled Photoresponse in GaOOH/Reduced Graphene Oxide Composites for Ultraviolet-C Photodetectors
Abstract GaOOH/reduced graphene oxide (rGO) composites are investigated for UVC photodetection with a defect-controlled photoresponse. The morphology and crystallinity of GaOOH grown on rGO are strongly influenced by the Ga(NO3)3 concentration. Excess precursor induces GaOOH aggregation, reducing the effective GaOOH/rGO interfacial area and generating trap states in GaOOH. These traps act as recombination centers that shorten...
Efficient conversion of carbohydrates into 2,5-diformylfuran using Bi2O3-Cr2O3 supported on N-doped carbon Nanotubes: A green tandem approach
Abstract The development of sustainable catalytic systems for biomass valorization is of great importance in the transition toward renewable energy and green chemical processes. In this study, a noble-metal-free Bi2O3-Cr2O3 catalyst supported on nitrogen-doped carbon nanotubes (N-CNT) was developed for the aerobic conversion of carbohydrates into 2,5-diformylfuran (DFF) using molecular oxygen as the oxidant. The catalytic...
PICA: Interpretable imputation for randomly missing data
Abstract Missing data is a commonly encountered problem in practice that can degrade the performance of predictive models and distort statistical inference. Many advanced imputation techniques suffer from a lack of interpretability, operating as “black boxes”. This paper introduces Parameter-based Imputation via Cycle-ensemble Averaging (PICA), a novel framework that first estimates distributional parameters directly from...
Ni(OH)2 interfaced with P-derived species electrocatalyst supported on hydrophilically modified carbon rods for enhanced acidic water splitting
Abstract The development of durable, earth-abundant electrocatalysts for acidic water electrolysis is critical for large-scale green hydrogen production. Herein, we report a simple strategy to fabricate high-performance bifunctional electrodes by directly electrodepositing Ni(OH)2 nanostructures interfaced with P-derived species onto chemically activated, hydrophilic carbon rod substrates. Surface oxidation of the carbon rod effectively removes surface impurities, enhances...
Ethylene glycol-modified NiFe LDH as a bifunctional electrocatalyst for alkaline water electrolysis
Abstract Developing cost-effective, durable, and efficient bifunctional electrocatalysts is essential for advancing green hydrogen production. Here, we report a rapid, one-step, room-temperature, corrosion-driven strategy for directly constructing nickel-iron layered double hydroxides (NiFe LDH) on nickel foam (NF), where the NF serves as both the conductive substrate and the sole Ni source. In an Fe3 + -ethylene glycol...
CCGCN: a complex composition graph convolutional network for temporal knowledge graph reasoning
Abstract Temporal knowledge graphs (TKGs) represent real-world facts evolving over time by incorporating the multirelational structure of knowledge graphs with temporal dimensions. While extensions of graph convolutional networks, such as relational and composition-based variants, have demonstrated strong capabilities in modeling graph-structured data, effectively capturing both symmetric and asymmetric relational dependencies, their application to TKG reasoning...
Non-pinched hysteresis in CrOx/TiOy-based memristive devices: Modeling and analysis
Abstract Transition-metal oxide memristors are promising for neuromorphic computing, yet most SPICE models overlook material-specific effects such as oxygen stoichiometry and non-pinched hysteresis. Here, we systematically study CrOx/TiOy memristors fabricated under controlled oxygen concentrations (10%–50%) and propose an improved SPICE-compatible model. The devices exhibit oxygen-dependent resistive switching, retention, and pulse-driven plasticity, with optimal performance at 40%...
