The Dimensional Revolution of Phosphorus: From Allotropicity to Battery System Applications
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Phosphorus‐based materials are promising high‐capacity anodes classified by dimension (0D–3D) to systematically explore their properties and composite strategies. When combined with materials such as carbon to form heterostructures, the electrical conductivity and stability are effectively enhanced.

A practical criterion for positivity of transition densities [PDF]
, 2014 We establish a simple criterion for locating points where the transition density of a degenerate diffusion is strictly positive. Throughout, we assume that the diffusion satisfies a stochastic differential equation (SDE) on $\mathbf{R}^d$ with additive ...

Epilepsia, EarlyView.Abstract Objective Epileptic seizures are generated in cerebral networks that propagate ictal and interictal activity. The structure of cerebral networks underpinning epileptic activity can be inferred from diffusion‐weighted magnetic resonance imaging (DWI).

Receiver architectures for positioning with low earth orbit satellite signals: a survey
EURASIP Journal on Advances in Signal Processing, 2023 Positioning, Navigation and Timing (PNT) are services generally provided by Global Navigation Satellite Systems (GNSS). GNSS reside in medium to high orbital altitudes from the Earth’s surface, resulting in weak signal reception.

National and Subnational Models of Care That Support Primary Health Care: A Mixed‐Methods Study
The International Journal of Health Planning and Management, EarlyView.ABSTRACT In 2020, the World Health Assembly called on countries to reorient their models of care (MOCs) toward primary health care (PHC). This study's objectives were to (a) describe common use of the concept of MOC; and (b) identify implemented MOCs and their components that support PHC at national and subnational levels. A scoping review charted data
