Effect of Freeze–Thaw Action on Mesostructure of Ecological Fiber Reinforced Loess
Advances in Civil EngineeringTraditional chemical additives inevitably pollute, damage, and destroy the ecological environment and natural resources while simultaneously addressing the requirements of engineering construction in loess areas.

Efficient multiple‐robust estimation for nonresponse data under informative sampling
Scandinavian Journal of Statistics, EarlyView.Abstract Nonresponse in probability sampling presents a long‐standing challenge in survey sampling, often necessitating simultaneous adjustments to address sampling and selection biases. We develop a statistical framework that explicitly models sampling weights as random variables and establish the semiparametric efficiency bound for the parameter of ...

A statistical investigation of pre-earthquake ionospheric TEC anomalies
Geodesy and Geodynamics, 2011 Previous researches show that the total electron content (TEC) in the ionospheric exhibits anomalous disturbances a few days or hours prior to earthquakes.

Giant Porphyry Copper Deposits Caused by a Slab Jamming in the Mantle Transition Zone
Terra Nova, EarlyView.ABSTRACT Two giant porphyry copper deposits in the Southern Central Andes formed during the Miocene–Pliocene transition when a bend in the subducting Juan de Fernández hotspot chain jammed in the mantle transition zone, causing mega‐scale slab‐kinking. This geometry implies mechanical resistance that caused East–West compression and eventually a thrust‐

Terra Nova, EarlyView.ABSTRACT In this study, we examine the relationship between Brune stress drop and fault slip where the stress drop is estimated using the Empirical Green's Function (EGF) method and slip distribution is derived from seismic and geodetic data inversion.

Team Cognition Research Is Transforming Cognitive Science
Topics in Cognitive Science, EarlyView.Abstract About 30 years ago, the Dynamical Hypothesis instigated a variety of insights and transformations in cognitive science. One of them was the simple observation that, quite unlike trial‐based tasks in a laboratory, natural ecologically valid behaviors almost never have context‐free starting points.

Satellite Remote Sensing in Seismology. A Review
Remote Sensing, 2009 A wide range of satellite methods is applied now in seismology. The first applications of satellite data for earthquake exploration were initiated in the ‘70s, when active faults were mapped on satellite images.

Experimental Analysis of Rainfall-Induced Instability and Failure Patterns in Loess Fill Slopes
Advances in Civil EngineeringDue to the complex terrain and topographical constraints of the Loess Plateau, flat land suitable for engineering construction is extremely limited. To address this issue, filling gullies and leveling land has become a common solution, resulting in the ...
