Coronal radiation of a cusp of spun-up stars and the X-ray luminosity of Sgr A*

, 2011
Chandra has detected optically thin, thermal X-ray emission with a size of ~1 arcsec and luminosity ~10^33 erg/s from the direction of the Galactic supermassive black hole (SMBH), Sgr A*.

How do galaxies acquire their mass? [PDF]

, 2011
We introduce a toy model that describes (in a single equation) the mass in stars as a function of halo mass and redshift. Our model includes the suppression of gas accretion from gravitational shock heating and AGN jets mainly for M_halo > M_shock ~ 10 ...

Hyperspectral Leaf Reflectance Detects Interactive Genetic and Environmental Effects on Tree Phenotypes, Enabling Large‐Scale Monitoring and Restoration Planning Under Climate Change

Plant, Cell &Environment, Volume 48, Issue 3, Page 1842-1857, March 2025.
ABSTRACT Plants respond to rapid environmental change in ways that depend on both their genetic identity and their phenotypic plasticity, impacting their survival as well as associated ecosystems. However, genetic and environmental effects on phenotype are difficult to quantify across large spatial scales and through time.

Re‐evaluation of pullulan (E 1204) as a food additive and new application for its extension of use

EFSA Journal, Volume 23, Issue 3, March 2025.
Abstract The present opinion deals with the re‐evaluation of pullulan (E 1204) when used as a food additive and with the new application on the extension of use to several food categories. Pullulan (E 1204) is obtained by fermentation of a food‐grade hydrolysed starch with non‐genetically modified Aureobasidium pullulans ■■■■■.

Biomechanical mechanisms underlying exosuit-induced improvements in walking economy after stroke [PDF]

, 2018
Stroke-induced hemiparetic gait is characteristically asymmetric and metabolically expensive. Weakness and impaired control of the paretic ankle contribute to reduced forward propulsion and ground clearance—walking subtasks critical for safe and ...
