This study examined the prevalence, stability, and fluidity of sexual orientation as well as the prevalence of gender discontent. From a community sample (i.e., all adolescents of the age cohort were invited), this study analyzed data from 1513 adolescents (50.5% females), who replied to questions about sexual attraction on at least one of three occasions (age 14: n = 623; age 15: n = 1322; and ag

Obesity is a known risk factor for poor breast cancer outcomes, but its impact on endocrine therapy efficacy remains unclear. While the ATAC trial suggests reduced effectiveness of aromatase inhibitors (AIs) in women with obesity, the BIG 1–98 trial found no significant differences. Clinical and biological evidence indicates that obesity may impair AI efficacy by increasing aromatase activity and

Green ammonia synthesis from nitrogen via photocatalysis and electrocatalysis has emerged as a pivotal research focus in sustainable chemical processes. The efficient catalytic reduction of nitrogen necessitates concurrent nitrogen activation and hydrogen evolution suppression, representing a significant challenge. In this study, CuAu bimetallic-modified TiO2 catalysts were developed and engineere

Large cardiac rhabdomyomas can disturb hemodynamic flow. Tuberous sclerosis complex is the most common cause of cardiac rhabdomyoma in fetuses. Recently, a mammalian target of rapamycin (mTOR) inhibitor effectively treated rhabdomyomas associated with tuberous sclerosis. Here, we report the effectiveness of an mTOR inhibitor in treating a fetus with large rhabdomyomas exhibiting severe heart failu

Trimetallic nickel–iron–molybdenum oxides are excellent electrocatalysts for alkaline water electrolysis despite experiencing severe molybdenum dissolution. While the impact of molybdenum on fresh samples is well-understood, its substantial loss during operation without compromising performance presents a unique puzzle. Here, we show that the initial presence of molybdenum induces the formation of

This study investigates the influence of polypropylene fibres (PF) on concrete performance across a finely resolved dosage spectrum (0.0–2.0% by cement mass, in 0.1% increments) using 2,100 laboratory specimens. The experimental programme evaluated compressive strength, tensile strength (flexural and splitting), modulus of elasticity, and water penetration depth. Predictive modelling was conducted

Trelleborg fortresses – the dream architecture of the Viking Age. In 1934, few decades after the idea of the existence of Jomsborg had been critically rejected, a geometric Viking fortress was surprisingly discovered on Zealand, named after the site, a so called Trelleborg fortress. This was followed by the search for more fortresses all over Scandinavia, a search that is still ongoing. Their ramp

This article elaborates on the embodiment of heritage via dressing practices in several rural and urban Nordic communities in the United States. Getting dressed is a shared human practice that we engage in and repeat most days, and for special occasions, traditional dress, or folk costume, comes into particular focus. I approach dressing in folk costume as a “situated embodied practice,” a mode of

Drawing on actor-network theory and theories of performance, this article discusses gift-giving as an expansive form of materializing relationships and delimiting boundaries between nations, regions, organizations and individuals in the wake of migration. Initially, I discuss gift-giving as a way of materializing relationships and building networks. Thereafter, I map out the social life of the Vär

We reviewed papers on optimal conjunctive use of surface and groundwater (GW) with application in dry regions. Selected papers from the last 25-year period were reviewed using the PRISMA method. We show that with increasing scarcity of water, objectives of models developed for optimal conjunctive use have become more environmentally and socially oriented. About two-thirds of the studies are dedica

Over the past century, Syria and the broader Middle East and North Africa (MENA) region have undergone profound demographic and economic transformations, yet they remain marked by deep regional, ethnic, and gender-based inequalities. These divisions have shaped development trajectories and contributed to social fragmentation, while successive waves of migration carried these dynamics abroad, from

This paper investigates the magnitude and drivers of ethnic and religious disparities in Female Labor Force Participation (FLFP) in Syria. Using census data and the Gelbach decomposition method, the analysis reveals substantial FLFP gaps across groups, reaching up to 18 percentage points. To understand the factors underlying these gaps, the analysis exploits the heterogeneity in economic developme

Developing a robust decision analysis framework for selecting appropriate building envelope assemblies is essential to ensure moisture safety, energy efficiency, and sustainability. Recently, Bayat Pour et al. introduced the inutility decision analysis (IDA) method, which integrates moisture safety criteria with sustainability considerations, including economic and environmental aspects. This stud

By combining ultrashort laser pulses with PEEM, time-resolved photoemission electron microscopy (TRPEEM) provides a powerful approach for investigating ultrafast charge carrier dynamics with simultaneous femtosecond temporal resolution and nanometer spatial precision. It has evolved into a versatile methodto study a wide range of phenomena, including charge carrier dynamics, surface plasmons, scat
