Accelerated glacier mass loss in the southeastern Tibetan Plateau since the 1970s

open access: yesAdvances in Climate Change Research, 2023
The southeastern Tibetan Plateau (SETP) is a region in High Mountain Asia with the most serious glacier mass loss. However, long-term and large regional-scale studies that estimate glacier mass balance in this area remain limited.

Global hot-star wind models for stars from Magellanic Clouds

open access: yes, 2017
We provide mass-loss rate predictions for O stars from Large and Small Magellanic Clouds. We calculate global (unified, hydrodynamic) model atmospheres of main sequence, giant, and supergiant stars for chemical composition corresponding to Magellanic ...

Radio emission from the massive stars in the Galactic Super Star Cluster Westerlund 1 [PDF]

open access: yes, 2009
Current mass-loss rate estimates imply that main sequence winds are not sufficient to strip away the H-rich envelope to yield Wolf-Rayet (WR) stars. The rich transitional population of Westerlund 1 (Wd 1) provides an ideal laboratory to observe mass-loss

Rate of Mass Loss Across the Instability Threshold for Thwaites Glacier Determines Rate of Mass Loss for Entire Basin [PDF]

open access: yesGeophysical Research Letters, 2018
AbstractRapid change now underway on Thwaites Glacier (TG) raises concern that a threshold for unstoppable grounding line retreat has been or is about to be crossed. We use a high‐resolution ice sheet model to examine the mechanics of TG self‐sustained retreat by nudging the grounding line just past the point of instability.

Constraints on porosity and mass loss in O-star winds from modeling of X-ray emission line profile shapes [PDF]

open access: yes, 2013
We fit X-ray emission line profiles in high resolution XMM-Newton and Chandra grating spectra of the early O supergiant Zeta Pup with models that include the effects of porosity in the stellar wind.

CMF models of hot star winds I. Test of the Sobolev approximation in the case of pure line transitions

open access: yes, 2010
We provide hot star wind models with radiative force calculated using the solution of comoving frame (CMF) radiative transfer equation. The wind models are calculated for the first stars, O stars, and the central stars of planetary nebulae.

Prediction Method of Steel Corrosion Rate Based on the Helix Distributed Sensor

open access: yesMicromachines, 2022
Corrosion of steel bars is of great significance for safety and service life of reinforced concrete structures. This work develops a prediction method for steel corrosion mass loss rate before the crack of concrete structure based on a spiral distributed

Study on Corrosion Resistance of Basalt Fiber in Guizhou

open access: yesKuangchan zonghe liyong
This is an article in the field of ceramics and composites. In order to explore the resistance of basalt fiber to acid and alkali corrosion, basalt fiber with or without wetting agent was soaked in 3 mol/L sulfuric acid solution and sodium hydroxide ...

Prevalence and Trajectory of Household Material Hardship Among Children With Advanced Cancer

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background/Objectives Families of children with advanced cancer living in poverty experience inferior outcomes including poor parent mental health and worse child quality of life. Household material hardship (HMH: food, housing, transportation, and/or utility insecurity) is a modifiable poverty exposure—and potential intervention target—that ...
