Eruption Dynamics and Hydrological Implications of Basaltic Volcanic Centres at Lake Taupo [PDF]

open access: yes, 2010
The Taupo Volcanic Centre (TVC) is a major rhyolite centre within the Taupo Volcanic Zone, yet a small volume of the centre is comprised of monogenetic basalt volcanoes. Four TVC basalts that lie north of Lake Taupo have been examined in this study: the

Coronary Perforation During Excimer Laser Angioplasty in a Patient With Prior Thoracic Radiotherapy

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Management of heavily calcified coronary lesions remains challenging despite advances in plaque‐modifying technologies. Excimer laser coronary angioplasty (ELCA) is an effective adjunctive strategy with a low risk of no‐reflow. Case Summary A 75‐year‐old woman with non–ST‐segment elevation acute coronary syndrome and severe left ...

The Rich Chemistry of Ionized Methanol With Sulfur Dioxide: Pathways to Prebiotic and Elusive Species in Earth's Atmosphere and Space

open access: yesChemistry – A European Journal, EarlyView.
The reaction between the methanol radical cation and sulfur dioxide is remarkably fast and forms several ionic and neutral products (HOSOH+, CH2OSO+, CH2OH+, CH2O, H2O, HSO2). The chemistry goes beyond simple proton or hydrogen transfer, revealing a close interaction between the two species, relevant to atmospheric and astrochemical environments where ...

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Jaw‐specific stem cell dynamics are associated with distinct enamel architecture in mouse incisors

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The continuously growing mouse incisor serves as a model for stem cell‐driven tooth renewal. Although mice possess maxillary and mandibular incisors, most studies have focused on the mandible. Potential differences in structure and renewal between these serially homologous organs remain insufficiently characterized.

Orthodentine‐osteodentine and osteocytic‐anosteocytic transition inferred from Silurian stem chondrichthyan dermal jawbones with ever‐white teeth overgrown by brown denticles

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The dentigerous jawbones of a 423‐million‐year‐old stem chondrichthyan (ischnacanthid acanthodian) carry a characteristic combination of multi‐row non‐shedding white teeth with brownish overgrowing denticles. The color distinction makes it a good model for observing the interaction between two odontode lineages, but the nature of ...

Dominant Lithium‐Ion Conduction and Desolvation Regulation Enabled by Lithiated Monodisperse Nanospheres Composite Separator for High‐Nickel Lithium Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
To match high‐nickel lithium batteries, a composite separator is designed using a sulfonation‐lithiation nanosphere coating modification strategy. The composite separator can enhance the selectivity of lithium‐ion transport, accelerate Li+‐desolvation, and capture Ni, Co, and Mn ions.

Armageddon and its aftermath: dating the Toba super-eruption

open access: yes, 2012
No-one alive today has witnessed a volcanic eruption remotely as big as the Toba "super" eruption. But our ancestors may have done, tens of thousands of years ago, when northern Sumatra exploded, creating a caldera now filled by the largest volcanic lake

Proteomic signatures of equine dental tooth tissues in ageing and disease

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Ageing and dental disease in horses lead to structural and functional deterioration of dental tissues, yet their molecular signatures remain poorly characterised. Understanding how these processes alter the protein composition of enamel, dentin, cementum and pulp is essential for improving equine oral health and identifying ...

Cheek tooth extraction in geriatric versus non‐geriatric horses

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Age‐related dental changes are major contributors to dental disorders in older horses, and cheek tooth extractions are often required to maintain masticatory function and oral comfort. However, limited information is available on clinical and treatment characteristics in this older patient population.
