Aligning electric vehicle (EV) charging with periods of abundant clean energy is essential for decarbonizing transportation. In solar-dominated grids, this requires shifting charging to midday hours – when vehicles are typically parked at workplaces. Yet workplace charging networks operate under institutional constraints such as shared infrastructure, bundled parking and charging services, and limited willingness to require drivers to move vehicles, making time-of-day pricing and active management difficult to implement. In a natural field experiment (n = 629 drivers) across a large workplace

This study examines the mediating and moderating role of metacognitive awareness in the relationship between self-regulated learning and mathematics achievement of university students in Ghana. Although self-regulated learning has attracted attention as a predictor of academic performance, few studies have examined how metacognitive awareness interacts with self-regulated learning to influence mathematics achievement in the Ghanaian context. A quantitative cross-sectional design was employed. Data were collected from 315 university students, representing a population of 3,240, using a structur

Probiotics, defined as living microorganisms, are widely recognized for their ability to positively influence the gut microbiota, an effect increasingly linked to a wide array of health benefits. They are claimed to treat or prevent conditions ranging from infant colic to cardiovascular disease, respiratory infections, and certain cancers. Since the beginning of the 21st century, consumer demand for probiotic-enriched foods has risen significantly, propelled by these health assertions. The consumption of such products has been associated with the alleviation of disorders, including irritable b

The incretin hormone glucagon-like peptide-1 (GLP-1) exerts potent effects on glucose metabolism, prompting the development of therapeutic strategies that enhance activity of the GLP-1 receptor (GLP-1R) pathway. Inhibitors of dipeptidyl peptidase 4 (DPP-4) prolong the half-life of endogenous GLP-1 and typically achieve reductions in HbA1c of 0.5%-0.8%. However, large-scale cardiovascular (CV) outcomes trials (CVOTs) with DPP-4 inhibitors demonstrated CV safety but did not show a reduction in CV events. A second incretin-based therapeutic approach was the development of GLP-1R agonists (GLP-1RA

Abstract Loss of lean mass in proportion to total weight loss is observed with incretin mimetic therapies such as tirzepatide and has the potential to adversely affect health and function. Apitegromab is an investigational, fully human monoclonal antibody that selectively inhibits myostatin activation and is, thereby, capable of increasing muscle mass. In the randomized, double-blind, placebo-controlled phase 2 EMBRAZE study, adults with overweight or obesity ( n = 102) were randomized 1:1 to receive tirzepatide plus apitegromab (10 mg kg −1 ) or tirzepatide plus placebo.

ABSTRACT The peculiar velocity field of the local Universe provides direct insights into its matter distribution and the underlying theory of gravity, and is essential in cosmological analyses for modelling deviations from the Hubble flow. Numerous methods have been developed to reconstruct the density and velocity fields at $z \lesssim 0.05$, typically constrained by redshift-space galaxy positions or by direct distance tracers such as the Tully–Fisher relation, the Fundamental Plane, or Type Ia supernovae. We introduce a validation framework to evaluate the accuracy of these reconstructions

BACKGROUND AND AIMS: Atherosclerosis is a chronic lipid-driven inflammatory disease and one of the leading underlying causes of cardiovascular morbidity and mortality in Western society. Macrophages are key players in atherosclerotic development. Although the cellular composition of carotid atherosclerotic lesions has been determined, macrophage population definitions lack granularity and lineage data. Moreover, to date no direct link has been established between cellular content of atherosclerotic lesions and secondary clinical outcome. This study is aimed at characterization of atherosclerot

Generative AI tools such as ChatGPT now perform core cognitive operations—reasoning, synthesis, evaluation, and creative generation—on users' behalf, raising urgent questions for educational psychology about how AI use relates to cognitive development. Yet research on cognitive offloading has largely treated AI use as a unidimensional phenomenon, obscuring a theoretically consequential distinction: whether AI substitutes for the user's own thinking or scaffolds it. Drawing on the autonomous–dependent help typology and self-determination theory, the present study introduces and examines a disti

Protein lactylation emerges as a pivotal metabolic rheostat, translating microenvironmental lactate flux into stable programs that orchestrate cancer treatment resistance. This review synthesizes recent advances under the framework of "Lactylation Switch in Cancer Vulnerabilities." We dissect the dominant enzymatic pathways (AARS1/2, KATs, HDACs) and non-enzymatic mechanisms (MGO/LGSH), alongside their critical structural underpinnings. Furthermore, we delineate how lactylation signals are interpreted by specific readers (e.g., TRIM33), directly reprogram non-histone protein function through s

To efficiently implement plasma and cerebrospinal fluid (CSF) biomarkers for staging and prognosis of Alzheimer disease (AD), we must understand their dynamics across disease progression. We analyzed participants from the Swedish BioFINDER-2 study with mass spectrometry measurements of plasma and CSF tau species, including eMTBR-tau243/MTBR-tau243 and phosphorylation occupancies (%p-tau). Disease duration was estimated using Aβ-PET and tau-PET with the SILA algorithm. Bootstrapped LOESS models showed that %p-tau217 changes earliest, increasing just before Aβ-PET positivity.

Additionally, while the importance of achievement emotions among tertiary‐level EFL learners has been well established, research on retrospective outcome emotions (e.g., pride and shame) among non‐tertiary EFL learners remains scarce.

Fermented foods and probiotics represent complementary yet distinct components of human nutrition. Fermented foods are shaped by biochemical transformations driven by microbial metabolism, whereas probiotics are live microorganisms that may confer health benefits to the host. In both cases, bacteria, yeasts, and filamentous fungi mediate key metabolic activities that generate bioactive compounds and modulate host-microbiota interactions. During fermentation, microbial communities synthesize organic acids, peptides, exopolysaccharides, vitamins, and other metabolites that enhance food safety, s

This work used a simple technique to prepare a novel cerium titanate nano-rods embedded in a cellulose-based hydrogel with high photo catalytic degradation activity. The composite hydrogel was prepared by embedding different amounts of cerium titanate nano-rods (Ce/Ti-NRs) into a crosslinked carboxymethyl cellulose/polyacrylamide polyelectrolyte complex (CMC/PAM) as a matrix material. The physico-chemical properties of the Ce/Ti-NRs, CMC/PAM, and cerium titanate nano-rods embedded in a cellulose-based hydrogel (Ce/Ti-NRs/CMC/PAM) were investigated by FT-IR, XRD, BET, TEM, SEM, and EDX techniqu

Abstract This article provides the first comprehensive global evidence on people’s fairness and efficiency preferences, beliefs about the sources of inequality and the efficiency cost of redistribution, and policy attitudes toward redistribution. Using a globally harmonized consequential experiment with more than 65,000 individuals across 60 countries, we show that the source of inequality plays a substantially larger role for inequality acceptance than the efficiency cost of redistribution. At the global level, implemented inequality increases by 85% when inequality is caused by merit rather
