Numerical Modeling of the Recession and Closure of Planar Hydraulic Fractures: Contact‐Based Versus Asymptotic‐Informed Schemes

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT We compare two algorithms to simulate the propagation, arrest, recession, and closure of a planar hydraulic fracture, focusing on their ability to capture the physical processes governing fracture recession and closure. The first algorithm is based on a fixed grid with contact detection during recession, while the second is based on a moving ...

Exploring the Physical Properties of Novel Inorganic Perovskite AMgBr3 (A = Ga, Na, Tl)

Nano Select, EarlyView.
The band gap values of AMgBr3 (A = Na, Ga, and Tl) perovskites were calculated using various exchange‐correlation functionals such as generalized gradient approximation (GGA)‐Perdew–Burke–Ernzerhof (PBE), GGA‐PBEsol, GGA‐WC, Hybrid HSE06, and Tran–Blaha modified Becke–Johnson (TB‐mBJ) methods.

Relevance of standardized phase angle and bioelectrical impedance vectors in hospitalized older patients: A cohort study

Nutrition in Clinical Practice, EarlyView.
Abstract Background The prognostic significance of standardized phase angle (StPhA) and bioelectrical impedance vector analysis (BIVA) remains unclear among hospitalized older individuals. Our study aimed to investigate the prognostic significance of StPhA and BIVA patterns concerning overall survival in hospitalized older patients.

Autorotating dispersal units of Getonia floribunda Roxb. (Combretaceae): morphology, aerodynamics and geometrical significance

Nordic Journal of Botany, EarlyView.
Dispersal units that continuously rotate while falling purely due to aerodynamic forces are called autorotating dispersal units. Single‐ to multi‐winged forms of autorotating dispersal units occur in nature. The dispersal unit of Getonia floribunda Roxb.

A Large Magneto‐Optical Trap of Cadmium Atoms Loaded From a Cryogenic Buffer Gas Beam

Natural Sciences, EarlyView.
We demonstrate laser cooling and trapping of cadmium atoms using deep‐ultraviolet light at 229 nm, capturing more than 1×107$1\times10^{7}$ atoms within 10 ms from a compact 5 cm Zeeman slower and cryogenic beam source. We achieve peak densities of 2.5×1011cm−3$2.5\times10^{11} \,\text{cm}^{-3}$ and phase‐space densities of 2×10−9$2\times10^{-9}$.

Patterns of wild meat and other protein consumption in the periphery of Salonga National Park, Democratic Republic of the Congo

People and Nature, EarlyView.
Abstract In Central Africa, human activities are severely impacting terrestrial and aquatic wildlife, threatening the food security of millions of people. Accordingly, sustainable use of wildlife is crucial for the nutrition and livelihoods of many rural communities in the region.
