SNOWMIP2: An evaluation of forest snow process simulation [PDF]

, 2009
The Northern Hemisphere has large areas that are forested and seasonally snow covered. Compared with open areas, forest canopies strongly influence interactions between the atmosphere and snow on the ground by sheltering the snow from wind and solar ...

Micrometeorological processes driving snow ablation in an Alpine catchment [PDF]

, 2011
Mountain snow covers typically become patchy over the course of a melting season. The snow pattern during melt is mainly governed by the end of winter snow depth distribution and the local energy balance.

The snow border [PDF]

Astronomy & Astrophysics, 2011
Context. The study of the snow line is an important topic in several domains of astrophysics, and particularly for the evolution of proto-stellar environments and the formation of planets. Aims. The formation of the first layer of ice on carbon grains requires low temperatures compared to the temperature of evaporation (T > 100 K).

From research to national expansion: 20 years' experience of community-based management of childhood pneumonia in Nepal

Bulletin of the World Health Organization
PROBLEM: Pneumonia is a leading cause of mortality of children aged under five in Nepal. Research conducted by John Snow Inc. in the 1980s determined that pneumonia case management by community-based workers decreased under-five mortality by 28 ...

Micro-mechanical insights into the dynamics of crack propagation in snow fracture experiments

Scientific Reports, 2021
Dry-snow slab avalanches result from crack propagation in a highly porous weak layer buried within a stratified and metastable snowpack. While our understanding of slab avalanche mechanisms improved with recent experimental and numerical advances ...

Strengthening person-centered care through quality improvement: a mixed-methods study examining implementation of the Person-Centered Care Assessment Tool in Zambian health facilities

HIV Research & Clinical Practice
Introduction Person-centered care (PCC) is considered a fundamental approach to address clients’ needs. There is a dearth of data on specific actions that HIV treatment providers identify as priorities to strengthen PCC.

Reconstruction of four-dimensional rockfall trajectories using remote sensing and rock-based accelerometers and gyroscopes [PDF]

Earth Surface Dynamics, 2019
This work focuses on the in-depth reconstruction of the full set of parameters of interest in single-block rockfall trajectories. A comprehensive understanding of rockfall trajectories holds the promise to enhance the application of numerical models for ...

Data‐Driven Bulldozer Blade Control for Autonomous Terrain Leveling

Advanced Robotics Research, EarlyView.
A simulation‐driven framework for autonomous bulldozer leveling is presented, combining high‐fidelity terramechanics simulation with a neural‐network‐based reduced‐order model. Gradient‐based optimization enables efficient, low‐level blade control that balances leveling quality and operation time.
