Investigating the spatio–temporal characteristics of lower atmospheric ducts across the China seas by performing a long–term simulation using the WRF model

open access: yesFrontiers in Marine Science
In this work, a diagnostic scheme for lower atmospheric ducts was established based on the Weather Research and Forecasting (WRF) model. More specifically, a 10-year simulation test was conducted for the China seas to investigate the spatio-temporal ...

Toward a Paradigm Shift in Low‐Temperature SCR Catalyst Design: Defect Engineering and Data‐Driven Integration

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work systematically reviews the key factors influencing the performance of low‐temperature NH3‐SCR. The mechanism and challenges of defect engineering strategies, such as oxygen vacancies, heteroatom doping, crystal facet exposure, and surface reconstruction, in controlling both activity and selectivity were analyzed.

Dexmedetomidine infusions improve cardiovascular and renal function in anaesthetised, experimentally endotoxaemic horses

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Dexmedetomidine infusions are beneficial in anaesthetised endotoxaemic horses when administered concurrent to endotoxin, but post‐conditioning effects are unknown. Objectives To evaluate whether a dexmedetomidine infusion is beneficial in horses administered Escherichia coli O55:B5 lipopolysaccharides (LPS) endotoxin prior to ...

What can 14 CO measurements tell us about OH? [PDF]

open access: yes, 2008
The possible use of 14CO measurements to constrain hydroxyl radical (OH) concentrations in the atmosphere is investigated. 14CO is mainly produced in the upper atmosphere from cosmic radiation.

Wildfire Emissions From European Boreal Fuels: Effects of Fuel Type and Moisture Content

open access: yesFire and Materials, EarlyView.
ABSTRACT The increasing severity of wildfires poses significant challenges through the release of greenhouse gases and other harmful gases and particles. Although field measurements exist, there is a lack of systematic data collection to understand the influence of moisture content on the particle and gas emissions of boreal fuels, particularly for ...

A Pan‐Cancer Single‐Cell Atlas of Bone Metastases Reveals Convergent Malignant Programs and Coordinated Immune Dysfunction

open access: yesiMetaMed, EarlyView.
A pan‐cancer atlas deciphers tumor‐induced reprogramming in bone metastases. Malignant evolution toward MYC/proliferation is a hallmark of bone metastases. Niche‐mediated immune dysfunction is characterized by immature pDCs, impaired antigen presentation and phagocytosis in TAMs, and exhausted T cells.
