Embryo Aggregation Promotes Derivation Efficiency of Outgrowths from Porcine Blastocysts [PDF]

open access: yesAsian-Australasian Journal of Animal Sciences, 2015
Porcine embryonic stem cells (pESCs) have become an advantageous experimental tool for developing therapeutic applications and producing transgenic animals.

Probabilistic description of the first-order Fermi acceleration in shock waves: Time-dependent solution by single-particle approach [PDF]

open access: yes, 2002
We give a new coherent description of the first-order Fermi acceleration of particles in shock waves from the point of view of stochastic process of the individual particles, under the test particle approximation.

Efficient and Moisture‐Stable Inverted Perovskite Solar Cells via n‐Type Small‐Molecule‐Assisted Surface Treatment

open access: yesAdvanced Science, 2023
Defect states at the surface and grain boundaries of perovskite films have been known to be major determinants impairing the optoelectrical properties of perovskite films and the stability of perovskite solar cells (PeSCs).

Regularity of the speed of biased random walk in a one-dimensional percolation model

open access: yes, 2017
We consider biased random walks on the infinite cluster of a conditional bond percolation model on the infinite ladder graph. Axelsson-Fisk and H\"aggstr\"om established for this model a phase transition for the asymptotic linear speed $\overline{\mathrm{

Covariant description of kinetic freeze out through a finite space-like layer [PDF]

open access: yes, 2005
The problem of Freeze Out (FO) in relativistic heavy ion reactions is addressed. We develop and analyze an idealized one-dimensional model of FO in a finite layer, based on the covariant FO probability. The resulting post FO phase-space distributions are

Primed pluripotent cell lines derived from various embryonic origins and somatic cells in pig. [PDF]

open access: yesPLoS ONE, 2013
Since pluripotent embryonic stem cell (ESC) lines were first derived from the mouse, tremendous efforts have been made to establish ESC lines in several domestic species including the pig; however, authentic porcine ESCs have not yet been established. It

Dusty Structure Around Type-I Active Galactic Nuclei: Clumpy Torus Narrow Line Region and Near-Nucleus Hot Dust [PDF]

open access: yes, 2009
We fitted Spitzer/IRS ~2-35 um spectra of 26 luminous QSOs in attempt to define the main emission components. Our model has three major components: a clumpy torus, dusty narrow line region (NLR) clouds and a blackbody-like dust.
