Cosmological Feedback from High-Redshift Dwarf Galaxies [PDF]

open access: yes, 2004
We model how repeated supernova explosions in high-redshift dwarf starburst galaxies drive superbubbles and winds out of the galaxies. We compute the efficiencies of metal and mass ejection and energy transport from the galactic potentials, including the

Photoresponsive Gas‐Permeable Membranes: Fundamentals, Innovations, and Prospects

open access: yesAdvanced Functional Materials, EarlyView.
Photoresponsive gas‐permeable membranes can be potentially used for smart packing, carbon capture, hydrogen purification, and optical gas valves due to their remote and non‐contact activation, precise spatial and temporal control, and reversible switching capabilities.

Beyond Ejection Fraction

open access: yesJACC: Cardiovascular Imaging, 2016
For nearly half a century, ejection fraction has been the mainstay of the assessment of left ventricular (LV) function. Although it has served clinicians well, it is only an indirect measure of cardiac function, derived from the change in volume of the LV cavity.

Ultrastable Perovskite Encased in a Helical Cage for Tunable Full‐Color Mirror‐Image Circularly Polarized Luminescence

open access: yesAdvanced Functional Materials, EarlyView.
Develop full‐color colloidal perovskite nanocrystal (PNC) composites using a single organic halide precursor and enhance their stability and emission through zirconium hydrogen phosphate nanosheets (NSs). Achieve high photoluminescence efficiency and dual‐state circularly polarized luminescence (CPL) by embedding stabilized PNCs into a chiral polymer ...

Galectin-3, advanced glycated end-products serum levels, endothelial function and cardiac hemo¬dynamics in post infarction heart failure patients with reduced and preserved ejection fraction.

open access: yesMedičnì Perspektivi, 2018
Epidemiological studies have reported that the rate of signs and symptoms of heart failure after myocardial infarction is approximately 25%. In addition, approximately 40% of myocardial infarctions are accompanied by left ventricular systolic dysfunction.

Cryogenic Focused Ion Beam Milling to Investigate the Anisotropic Magnetotransport Properties of Bismuth Microcrystals

open access: yesAdvanced Functional Materials, EarlyView.
The highly anisotropic Fermi surface of bismuth results in variations in magnetotransport properties across different crystallographic directions, which can be characterized by studying microcrystals. To avoid the observed surface melting under room temperature Focused Ion Beam (FIB) irradiation, two low‐temperature FIB fabrication methods are proposed
