Static recrystallization of shocked calcite in Ries impact breccias
Meteoritics &Planetary Science, EarlyView.Abstract Calcite is prone to chemical and microstructural modifications, especially after having been strained at high stresses and strain rates, as during hypervelocity impact events. These modifications include precipitation from pore fluid as well as replacement of strained volumes by recrystallization. In calcite aggregates of a metagranite breccia

Microspherules Formed by Lightning Strikes
Meteoritics &Planetary Science, EarlyView.Abstract Natural microspherules are formed by high‐temperature processes and are present throughout the geologic record to the present day. We report the discovery of large numbers of microspherules recovered from a rock pavement in the Pilbara region, Western Australia.

Iran's Forward Defense in Sub‐Saharan Africa
Middle East Policy, EarlyView.Abstract This article examines Iran's security and defense initiatives in sub‐Saharan Africa between 1990 and 2024 and how they reflect the extraterritorial application of the regime's forward defense doctrine. In response to the long‐term erosion of its homeland defense capabilities since the Iran‐Iraq War of the 1980s—driven by infrastructure ...

Studies of atmospheric refraction effects on laser data [PDF]
The refraction effect from three perspectives was considered. An analysis of the axioms on which the accepted correction algorithms were based was the first priority. The integrity of the meteorological measurements on which the correction model is based

Plant, Cell &Environment, EarlyView.ABSTRACT The rhizosphere harbours critical plant‐herbivore interactions often mediated by small lipophilic molecules (SLMs). Despite the agricultural importance of many soil‐dwelling insects, surprisingly little is known about chemically mediated belowground crop‐pest interactions. Root and shoot herbivores can influence these interactions by modifying
