Genesis and karst characteristics of marble agglomerate in volcanic rocks on the eastern slope of Wutong Mountain, Shenzhen

Carsologica Sinica
Karst phenomena, such as fissures and caves, occur in the marble agglomerate of pyroclastic rocks on the eastern slope of Shenzhen’s Wutong Mountain. These features have affected the engineering projects such as subway construction and pile foundation ...

Discrimination of hot versus cold avalanche deposits: Implications for hazard assessment at Mount Meager, B.C. [PDF]

Natural Hazards and Earth System Sciences, 2003
The surficial deposits surrounding the Mount Meager volcanic complex include numerous avalanche deposits. These deposits share many attributes: (a) they are nearly monolithologic and comprise mainly intermediate volcanic rock clasts, (b) they lack ...

Nanocatalytic Immunotherapy Targeting Tumor‐Resident Intracellular Bacteria for Triple‐Negative Breast Cancer Treatment and Metastasis Suppression

Advanced Science, EarlyView.
Bacteria residing within tumor cells contribute to breast cancer progression, but few therapies target their elimination. FeSe2 nanosheets coated with cancer cell membranes accumulate in tumors and generate reactive oxygen species under ultrasound, killing tumor cells and their harbored bacteria at the same time.

High‐elevation endemic plants predicted to lose habitat from changing climate in Washington State

American Journal of Botany, EarlyView.
Abstract Premise High‐elevation plants face unique challenges from potential climate change impacts that will likely require upslope migration into increasingly smaller suitable habitat. This situation is particularly acute for endemic species that by definition occupy small geographic ranges.

Fracture mechanics of volcanic eruptions [PDF]

, 2009
Seismology is a key tool in the forecasting of volcanic eruptions. The onset of an eruption is often preceded and accompanied by an increase in local seismic activity, driven by fracturing within the edifice.

Circulating Exosomes Drive Persistent Neuronal Dysfunction in Post‐Herpetic Neuralgia Patients

Annals of Neurology, EarlyView.
Proposed model of exosome‐mediated neuronal dysfunction in post‐herpetic neuralgia (PHN). (1) Circulating, non‐pathogenic exosomes maintain homeostatic processes in healthy skin, where sensory nerve fibers innervate the epidermis and dermis. (2) During acute zoster, reactivating varicella zoster virus (VZV) travels down neurites to the skin causing ...
