Bridging Retrieval Performance and Learning Outcomes: An Integrated Offline and Online Evaluation Framework for Retrieval-Augmented AI in Higher Education

This paper proposes an Integrated Offline–Online Evaluation Framework (IOEF) that links technical retrieval metrics with educational outcome evidence from existing literature to demonstrate that effective AI adoption in higher education requires balancing information-retrieval performance with instructional design rather than relying on retrieval benchmarks alone.

Addressing Childhood Trauma Through School-Based Mental Health Interventions: A Scoping Review of Trauma-Informed Approaches and Psychosocial Outcomes Among Vulnerable Youth in United States of America (USA)

This scoping review of 16 studies published between 2015 and 2025 finds that trauma-informed school-based interventions in the USA generally yield positive psychosocial outcomes for vulnerable youth, particularly through whole-school and multi-tiered approaches, though their long-term impact is often hindered by implementation challenges such as limited resources and staff turnover.

Comprehensive TCAD Investigation of RF Performance, Noise Characteristics, and Intrinsic Capacitances of InAlAs/InGaAs/InP HEMTs: Impact of Gate-to-Channel Distance and Gate Bias.

This study utilizes TCAD simulations to demonstrate that increasing the gate-to-channel distance in InAlAs/InGaAs/InP HEMTs generally reduces noise spectral densities and gate-to-drain capacitance while increasing output conductance and gate-to-source capacitance, whereas varying the gate bias produces distinct, often opposing, effects on current and voltage noise characteristics.

Does Political Alignment Deliver Justice? SC Rape Reporting, Conviction, and Trial Pendency Under Partisan Alignment in India, 2001–2022

This study of 20 Indian states from 2001 to 2022 finds that partisan alignment between state and central governments significantly improves justice outcomes for Scheduled Caste rape victims—increasing reporting, convictions, and trial efficiency—with a notably sharp reporting boost observed specifically under BJP-aligned regimes compared to INC-aligned ones.

Communication-space representation of multicellular tissue organization

The paper introduces CommuSpace, a computational framework that redefines multicellular tissue organization by mapping cells into a communication space based on ligand–receptor interactions, thereby revealing emergent "communication ecosystems" as a fundamental higher-order layer of tissue architecture that transcends traditional cell identity and spatial niche classifications.

Plant architecture reveals contrasting developmental strategies in two threatened West African timber species (Khaya senegalensisand Pterocarpus erinaceus): implications for conservation and sustainable forest management

This study provides the first comprehensive architectural characterization of the threatened West African timber species *Khaya senegalensis* and *Pterocarpus erinaceus*, revealing their distinct developmental models and plastic responses to environmental gradients to establish a scientific basis for optimizing their conservation, reforestation, and sustainable management.
