Lithopanspermia in Star Forming Clusters [PDF]

open access: yes, 2005
This paper considers the lithopanspermia hypothesis in star forming groups and clusters, where the chances of biological material spreading from one solar system to another is greatly enhanced (relative to the field) due to the close proximity of the systems and lower relative velocities. These effects more than compensate for the reduced time spent in

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.

Exploring Electronic States and Ultrafast Electron Dynamics in AlInP Window Layers: The Role of Surface Reconstruction

open access: yesAdvanced Functional Materials, EarlyView.
This study examines the surface characteristics of AlInP (001), crucial for advanced solar cells and photoelectrochemical devices. Using theoretical modeling and experiments, it identifies how phosphorus‐rich and indium‐rich surfaces create mid‐gap states that pin the Fermi level and influence ultrafast electron dynamics.

Ejection and Capture Dynamics in Restricted Three-Body Encounters [PDF]

open access: yes, 2012
We study the tidal disruption of binaries by a massive point mass (e.g. the black hole at the Galactic center), and we discuss how the ejection and capture preference between unequal-mass binary members depends on which orbit they approach the massive object.

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

open access: yesAdvanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

The dynamic ejecta of compact object mergers and eccentric collisions [PDF]

open access: yes, 2012
Compact object mergers eject neutron-rich matter in a number of ways: by the dynamical ejection mediated by gravitational torques, as neutrino-driven winds and probably also a good fraction of the resulting accretion disc finally becomes unbound by a combination of viscous and nuclear processes. If compact binary mergers produce indeed gamma-ray bursts

Tunable Thermoshrinkable Hydrogels for 4D Fabrication of Cell‐Seeded Channels

open access: yesAdvanced Functional Materials, EarlyView.
A thermoresponsive polymer with methacrylate groups for photo‐cross‐linking, based on polyethylene glycol, N‐isopropylacrylamide, and 2‐hydroxyethyl acrylate is synthetized to yield hydrogels that shrink upon temperature increase. The new polymer enables the fabrication of cell‐laden perfusable channels with diameters below 200 µm by combining ...

NEW EMPHASES ON THE STUDY OF THE PATHOGENESIS OF CHRONIC HEART FAILURE WITH PRESERVED EJECTION FRACTION: FOCUS ON INFLAMMATORY MARKERS

open access: yesРациональная фармакотерапия в кардиологии, 2015
For the long time the systolic myocardial dysfunction was traditionally associated with the severity of chronic heart failure (CHF). Increasing number of patients with symptoms of CHF but without systolic dysfunction has drawn the attention of ...
