Altermagnetism in two-dimensional CaRuO perovskite.

We propose and characterize a novel two-dimensional material, 2D-CRO, derived from bulk calcium-based ruthenates (CROs) of the Ruddlesden-Popper family, CaRuO ( = 1 and 2). Using density functional theory, we demonstrate that 2D-CRO maintains structural stability down to the monolayer limit, exhibiting a tight interplay between structural and electronic properties. Notably, 2D-CRO displays altermagnetic behavior, characterized by zero net magnetization and strong spin-dependent phenomena, stabilized through dimensionality reduction.

An Exploratory Investigation of Heritage and Educational Language Exposures as Factors in Medical Student Spanish Language Proficiency.

Background: Prior to enrolling in medical Spanish courses, students typically acquire their Spanish skills either through formal second language education only (L2 learners) or by being exposed to Spanish during childhood at home (heritage learners).

Objective: To categorize the language exposures of medical students who participated in a medical Spanish course and explore the associations of exposures with their medical language proficiency score on the Physician Oral Language Observation Matrix (POLOM).

Setting And Participants: Forty-one fourth-year medical students (2021-2022) self-reported demographics and prior language exposures and participated in videorecorded POLOM-rated Spanish standardized patient encounters.

The Transition to Kindergarten for Hispanic and Latine Autistic Children: A Focus Group Study with Caregivers.

Purpose: Past research highlights the different facilitators and barriers that caregivers of children on the autism spectrum experience during the transition to kindergarten and when navigating special education services. Caregivers who identify as Hispanic and/or Latine may face distinct challenges during this process, such as language differences, differences in understanding autism and special education, and barriers to advocating for their child. Hispanic and Latine caregivers also have strengths, resources, and strategies (i.

Registration of deaths in children under five years of age has improved in Mexico, however, the underreporting has not yet been eliminated.

Background: The underreporting of vital statistics poses a problem for the quality of information. To address underreporting, Mexico implemented the "Intentional Search for Children Deaths" in 2002.

Objective: To analyze trends in the underreporting of deaths in neonates and children under 5 years of age (U5) from 1992 to 2022 at the national level and by state.

From Semi-Infinite to Thin-Layer Diffusion─Effects of Finite Mass Transport on the Electrochemical Response of Redox Probes: Implications for Electroanalytical Measurements.

Electrochemistry in confined environments, that is, involving experimental configurations with spatial restrictions that affect the overall mass transport, is becoming a very attractive way of carrying out electroanalytical measurements for sensing, especially for the so-called thin-layer (TL) configuration, which ideally allows the complete conversion of the analytes under study in small volumes and short times. To improve the understanding of this kind of situation, general expressions for the current-potential-time and charge-potential-time responses of charge transfer processes taking place under finite diffusion conditions with two different configurations (no mass renovation, bounded diffusion; and effective mass renovation, unbounded diffusion) are discussed in this work. By using these expressions, it is possible to establish accurate limits for the attainment of TL conditions and to conclude that for bounded conditions, the charge is a more adequate quantity for electroanalytical purposes.
