A Radial Age Gradient in the Geometrically Thick Disk of the Milky Way [PDF]

open access: yes
In the Milky Way, the thick disk can be defined using individual stellar abundances, kinematics, or age, or geometrically, as stars high above the midplane.

Chemical constraints on the formation of the Galactic thick disk [PDF]

open access: yes, 2012
We highlight some results from our detailed abundance analysis study of 703 kinematically selected F and G dwarf stars in the solar neighbourhood. The analysis is based on spectra of high-resolution (R = 45 000 to 110 000) and high signal-to-noise (S/N ...

Developmental morphology of claspers and clasper‐glands during maturation in Potamotrygon wallacei (Chondrichthyes: Potamotrygoninae)

open access: yesThe Anatomical Record, EarlyView.
Abstract The claspers are the copulatory organs in male elasmobranchs, responsible for directing the semen into the female cloaca (C). However, the microscopic morphology of the claspers remains poorly understood. This study describes the morphology of the claspers and clasper glands (CGs) of cururu stingray (Potamotrygon wallacei) at different ...

Multifunctional hyaluronic acid hydrogel integrating exosome‐encapsulating gelatin microspheres accelerates skeletal muscle regeneration via TGF‐β1 activation and enhanced myogenic cell viability

open access: yesBMEMat, EarlyView.
Schematic illustration of preparation of injectable H/G@Co@miR‐206 hydrogel for efficient skeletal muscle regeneration in cardiotoxin‐induced skeletal muscle injury SD rat model. Abstract The effective treatment of acute skeletal muscle injuries remains challenging, necessitating therapeutic strategies that concurrently reestablish vascular perfusion ...

Mapping Atomic Hydrogen in the Disk of the Milky Way [PDF]

open access: yes, 2013
The VATLY radio telescope has been used to draw the map of atomic hydrogen gas in the disk of the Milky Way. Evidence has been obtained for its differential rotation, its cloud and arm structure and the presence of a dark matter ...

Metal nanostructure‐coupled label‐free localized surface plasmon resonance biosensors for rapid and sensitive disease diagnosis

open access: yesBMEMat, EarlyView.
LSPR biosensing enables rapid, sensitive, and low‐sample‐volume detection of biomarkers, with broad applications in diagnosing cancer, infectious, and chronic diseases. Advances in nanostructure design, micro/nanofabrication, and microfluidic integration have expanded the potential of LSPR sensors in biomedical diagnostics.

The Orbital Eccentricities of Planets in the Kinematic Thin and Thick Galactic Disks

open access: yesThe Astronomical Journal
The orbital eccentricity distribution of exoplanets is shaped by a combination of dynamical processes, reflecting both formation conditions and long-term evolution.

The Milky Way and other spiral galaxies

open access: yesEPJ Web of Conferences, 2012
Cosmologists have often considered the Milky Way as a typical spiral galaxy, and its properties have considerably influenced the current scheme of galaxy formation.

Hyperbranched poly‐L‐lysine surface‐engineered bioprosthetic heart valves with anti‐calcification, anti‐infection, and durability

open access: yesBMEMat, EarlyView.
The challenges of bioprosthetic heart valves (BHV) with respect to calcification, infection, and poor durability are tackled by surface engineering of hyperbranched poly‐L‐lysine (HBPL), providing a translational solution to improve long‐term valve performance.
