Theory suggests that animals make hierarchical, multiscale resource selection decisions to address the hierarchy of factors limiting their fitness. Ecologists have developed tools to link population-level resource selection across scales; yet, theoretical expectations about the relationship between coarse- and fine-scale selection decisions at the individual level remain elusive despite their importance to fitness. With GPS-telemetry data collected across California, USA, we evaluated resource selection of mountain lions (Puma concolor; n = 244) relative to spatial variation in human-caused mortality risk.

Presynaptic inhibition mediated by GABAergic interneurons provides regulation of sensory afferent feedback. Serotonin not only promotes locomotion, but also modulates feedback from sensory afferents, both directly and indirectly, potentially by acting on the GABAergic interneurons that mediate presynaptic inhibition.

- Discharge date prediction is essential for efficient healthcare management, helping with resource allocation and improving patient care by providing accurate estimates for when patients will leave the hospital.
- The study developed a prediction model using machine learning (XGBoost) and collaborated with clinical experts to gather relevant data, which was integrated into an Electronic Medical Record system for practical use.
- The model improved prediction accuracy significantly, reducing excess hospital days by nearly 19%, highlighting its effectiveness for enhancing healthcare resource management and patient outcomes, with recommendations for future research on its long-term applicability.
Locomotor behaviors are performed by organisms throughout life, despite developmental changes in cellular properties, neural connectivity, and biomechanics. The basic rhythmic activity in the central nervous system that underlies locomotion is thought to be generated via a complex balance between network and intrinsic cellular properties. Within mature mammalian spinal locomotor circuitry, we have yet to determine which properties of spinal interneurons (INs) are critical to rhythmogenesis and how they change during development.
