Permian-Triassic stable isotope stratigraphy of Australia
, 2009 The Permian-Triassic boundary mass extinction is the largest in the Phanerozoic and therefore is the major event in the Phanerozoic. The mass extinction cause is problematical but studying global geochemical and geophysical signatures about the Permian-

New Permo-Carboniferous geochemical data from central Thailand: implication for a volcanic arc model [PDF]
, 1991 Current ideas and models of geotectonic reconstructions of Southeast Asia are reviewed and new data on Late Carboniferous through Middle Permian tuffites and sills from central Thailand are presented in the light of the problems of Southeast Asian ...

Early Permian crinoids from Laurasia and their paleogeographic implications [PDF]
Acta Palaeontologica PolonicaA new crinoid fauna is described from the Trogkofel Group of the Southern Karavanke Mountains, Slovenia (lower Permian, Artinskian). This fauna is from a shallow platform or upper slope setting and is comprised primarily of isolated aboral cups.

The Permian Bacterium that Isn't
Molecular Biology and Evolution, 2001 There is growing evidence for the presence of viable microorganisms in geological salt formations that are millions of years old. It is still not known, however, whether these bacteria are dormant organisms that are themselves millions of years old or whether the salt crystals merely provide a habitat in which contemporary microorganisms can grow ...

The Effect of Managerial Ability on the Market Valuation of Unrecognized Tax Benefits
American Business ReviewThis study examines the effect of managerial ability on the market valuation of unrecognized tax benefits (UTBs). While UTBs are generally associated with significant risks, we hypothesize that highly able managers can enhance the market valuation of the

Deep Underground Science and Engineering, EarlyView.The fused data extracted from the distributed monitoring system as the data basis, combined with dynamic geological data, are imported into a deep learning model. As the geological conditions of mining and excavation change, the risk of water inrush at the working face is retrieved in real time.

Deep Underground Science and Engineering, EarlyView.This study assesses whether a saline aquifer in the German North Sea can sustain industrial‐scale CO2 injection at 10 Mt/year over 30 years. A 3D reservoir model is used to compare static capacity with dynamically achievable storage. The work links site‐scale injection strategy design with basin‐scale pressure response, providing a framework for ...

Vancomycin-induced Severe asymptomatic Immune Thrombocytopenia; a rare cause
Southwest Respiratory and Critical Care Chronicles, 2014 Drug-induced immune thrombocytopenia is a challenging clinical problem that is often overlooked. Vancomycin is a rare cause of immune-mediated thrombocytopenia that can cause severe life-threatening bleeding in an acutely ill patient.

Deep Underground Science and Engineering, EarlyView.This study proposes an exponentially‐constrained Gaussian mixture model (EcGMM) to quantify vertical fracture heterogeneity in stratified roof strata. The model integrates a piecewise exponential decay term capturing global stress dissipation with Gaussian components representing localized fracture intensification at lithological interfaces.
