Ideal partner preferences (i.e., ratings of the desirability of attributes like attractiveness or intelligence) are the source of numerous foundational findings in the interdisciplinary literature on human mating. Recently, research on the predictive validity of ideal partner preference matching (i.e., Do people positively evaluate partners who match vs. mismatch their ideals?) has become mired in several problems. First, articles exhibit discrepant analytic and reporting practices. Second, different findings emerge across laboratories worldwide, perhaps because they sample different relationship contexts and/or populations. This registered report-partnered with the Psychological Science Accelerator-uses a highly powered design ( = 10,358) across 43 countries and 22 languages to estimate preference-matching effect sizes. The most rigorous tests revealed significant preference-matching effects in the whole sample and for partnered and single participants separately. The "corrected pattern metric" that collapses across 35 traits revealed a zero-order effect of β = .19 and an effect of β = .11 when included alongside a normative preference-matching metric. Specific traits in the "level metric" (interaction) tests revealed very small (average β = .04) effects. Effect sizes were similar for partnered participants who reported ideals before entering a relationship, and there was no consistent evidence that individual differences moderated any effects. Comparisons between stated and revealed preferences shed light on gender differences and similarities: For attractiveness, men's and (especially) women's stated preferences underestimated revealed preferences (i.e., they thought attractiveness was less important than it actually was). For earning potential, men's stated preferences underestimated-and women's stated preferences overestimated-revealed preferences. Implications for the literature on human mating are discussed.

Innovative qualitative approaches are essential for exploring how health professions education (HPE) can address complex, value-laden constructs such as social accountability. Visual elicitation techniques, including rich picture interviews (RPIs), offer distinctive opportunities to surface layered, affective, and contextually embedded understandings. This methodological study examines participant perspectives on the use of RPIs within a broader qualitative interpretive description on social accountability.

Traumatic injury is the leading cause of death for individuals aged 1-45 in the USA. Variations in patient management based on geographic locations, community resources, and provider characteristics contribute to disparities in patient outcomes. It is estimated that 20,000 Americans lives could be saved yearly if all trauma centers performed as well as the highest-performing center, which is achievable, in part, through the reduction of inappropriate practice variation.

Background: Copper-mediated radiofluorination (CMRF) is a breakthrough in F-radiochemistry, enabling F incorporation into molecules even at electron-rich aromatic positions. In recent years, several improved protocols have been reported to advance the application of CMRF. These advancements primarily focus on improving radiochemical conversion, expanding substrate scope, and enabling scalability for remote-controlled radiotracer production.

There is no immunohistochemical or molecular marker to confirm the histologic diagnosis of pancreatic ductal adenocarcinoma (PDAC). This is particularly important in a scenario of unknown primary. Molecularly, PDAC is characterized by a limited set of driver mutations, and new predictive and prognostic markers are needed to guide novel therapies.

Spin-momentum-locked edge states of quantum spin Hall insulators provide a compelling platform for spintronic applications, owing to their intrinsic protection against backscattering from non-magnetic disorder. This protection emerges from time-reversal symmetry, which pairs Kramers partners of helical edge modes with opposite spin and momentum, thereby strictly forbidding elastic single-particle backscattering within the pair. Yet, contrary to the idealized notion of linear edge bands, the non-monotonic dispersions of realistic materials can host multiple Kramers pairs, reintroducing backscattering channels between them without violating time-reversal symmetry.
