Background: Delinquent behavior in adolescence is a prevalent issue, often associated with difficulties across multiple life domains, which in turn perpetuates negative life outcomes. While current treatment programs show partial success in improving behavioral changes and reducing recidivism, comprehensive conclusions regarding the overall efficacy of these interventions have yet to be established. In forensic outpatient settings, the discrepancy between adolescents' limited emotional awareness and the predominant emphasis on cognitive reflection, combined with low treatment adherence, may be factors that undermine treatment efficacy.

The current work seeks to understand how the interactions between ZnO QDs and extracellular polymeric substances (EPS) may vary based on the types of EPS (loosely and tightly bound) and modes of eco-corona formation (In-situ or ex-situ). In-situ eco-corona refers to formation of an EPS layer on the QDs during the interactions with the algae whereas the ex-situ condition refers to forming the layer before the interactions. ZnO QDs were added at 0.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Interfacial Dripping Faucet: Generating Monodisperse Liquid Lenses.

Phys Rev Lett

December 2024

Carlos III University of Madrid, Thermal and Fluids Engineering Department, Avenida de la Universidad, 30 (Sabatini building), 28911 Leganés (Madrid), Spain.

We present a surface analog to a dripping faucet, where a viscous liquid slides down an immiscible meniscus. Periodic pinch-off of the dripping filament is observed, generating a succession of monodisperse floating lenses. We show that this interfacial dripping faucet can be described analogously to its single-phase counterpart, replacing surface tension by the spreading coefficient, and even undergoes a transition to a jetting regime.

Lombarts is professor, Professional Performance & Compassionate Care Research Group, Department of Medical Psychology, Amsterdam University Medical Center, University of Amsterdam, and researcher, Quality of Care Program, Amsterdam Public Health Research Institute, Amsterdam, the Netherlands.

Purpose: Cultures of wellness, defined as shared norms, values, attitudes, and behaviors that promote personal and professional growth and well-being, are robust determinants of professional fulfillment and professional performance. A major and largely overlooked aspect of a culture of wellness in medicine is residents' perceived appreciation or experience of feeling valued. Considering the pressing workforce and retention challenges that residency programs face, this study addressed the following research questions: How does appreciation at work manifest in the eyes of residents and how do residents perceive appreciation in relation to their professional fulfillment and performance?

Method: Guided by an interpretative phenomenological approach, this qualitative study purposively sampled 12 residents from different specialties, training years, regions in the Netherlands, and genders.

Fast exact gap-affine partial order alignment with POASTA.

Bioinformatics

January 2025

Infectious Disease and Microbiome Program, Broad Institute of MIT and Harvard, Cambridge, MA 02142, United States.

Motivation: Partial order alignment is a widely used method for computing multiple sequence alignments, with applications in genome assembly and pangenomics, among many others. Current algorithms to compute the optimal, gap-affine partial order alignment do not scale well to larger graphs and sequences. While heuristic approaches exist, they do not guarantee optimal alignment and sacrifice alignment accuracy.
