Structural and signaling proteins in the Z-disk and their role in cardiomyopathies

Frontiers in Physiology, 2023
The sarcomere is the smallest functional unit of muscle contraction. It is delineated by a protein-rich structure known as the Z-disk, alternating with M-bands.

Thin disk kinematics from RAVE and the solar motion [PDF]

, 2012
Aims. We study the Milky Way thin disk with the Radial Velocity Experiment (RAVE) survey. We consider the thin and thick disks as different Galactic components and present a technique to statistically disentangle the two populations.

The Panchromatic Hubble Andromeda Treasury. XX. The Disk of M31 is Thick

The Astronomical Journal, 2023
We present a new approach to measuring the thickness of a partially face-on stellar disk, using dust geometry. In a moderately-inclined disk galaxy, the fraction of reddened stars is expected to be 50% everywhere, assuming that dust lies in a thin ...

Chemical constraints on the formation of the Galactic thick disk

EPJ Web of Conferences, 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 = 45000 to 110 000) and high signal-to-noise (S/N ...

The Chemical Evolution of the Galaxy: the two-infall model [PDF]

, 1996
In this paper we present a new chemical evolution model for the Galaxy which assumes two main infall episodes for the formation of halo-thick disk and thin disk, respectively. We do not try to take into account explicitly the evolution of the halo but we

The Gaia-ESO Survey: Separating disk chemical substructures with cluster models [PDF]

, 2015
(Abridged) Recent spectroscopic surveys have begun to explore the Galactic disk system outside the solar neighborhood on the basis of large data samples.

Analytical and Semi-Analytical Formulas for the Self and Mutual Inductances of Concentric Coplanar Ordinary and Bitter Disk Coils

Physics, 2021
In this paper, analytical and semi-analytical formulas are presented for the self- and mutual inductance of thin ordinary disk coils and thin Bitter disk coils. The coils lie concentrically in a plane.

Stochastic processes, galactic star formation, and chemical evolution. Effects of accretion, stripping, and collisions in multiphase multi-zone models [PDF]

, 2005
This paper reports simulations allowing for stochastic accretion and mass loss within closed and open systems modeled using a previously developed multi-population, multi-zone (halo, thick disk, thin disk) treatment.

Isotopic Titanium Abundances in Local M Dwarfs [PDF]

, 2009
Relative abundances of the five stable isotopes of titanium (^46Ti to ^50Ti) are measured for 11 M dwarfs belonging to the thin disk (four stars), thick disk (three stars), the halo (one star), and either the thick or the thin disk (three stars).

Polarized image of a Schwarzschild black hole with a thin accretion disk as photon couples to Weyl tensor

European Physical Journal C: Particles and Fields, 2021
We have studied polarized image of a Schwarzschild black hole with an equatorial thin accretion disk as photon couples to Weyl tensor. The birefringence of photon originating from the coupling affect the black hole shadow, the thin disk pattern and its ...
