Stochastic Biasing and Galaxy-Mass Density Relation in the Weakly Non-linear Regime
, 1999 It is believed that the biasing of the galaxies plays an important role for understanding the large-scale structure of the universe. In general, the biasing of galaxy formation could be stochastic.

Scintillation Response of 0D Cs3Cu2I5 Thin Layers to Light‐ and Heavy‐Ion Irradiation
Advanced Photonics Research, EarlyView.Driven by increasing interest in uncovering the remarkable photoluminescence quantum yield of Cs3Cu2I5, polycrystalline thin layers are synthesized to investigate its radioluminescence response to energetic ions. Its spectroscopic capability is assessed in a wide range of ion mass and internal excitation processes are explored.

A Revised Parallel-Sequence Morphological Classification of Galaxies: Structure and Formation of S0 and Spheroidal Galaxies [PDF]
, 2011 We update van den Bergh's parallel sequence galaxy classification in which S0 galaxies form a sequence S0a-S0b-S0c that parallels the sequence Sa-Sb-Sc of spiral galaxies. The ratio B/T of bulge to total light defines the position of a galaxy in each sequence. Our classification makes one improvement.

Genomic Insights into Post‐Domestication Expansion and Selection of Body Size in Ponies
Advanced Science, EarlyView.The authors’ research delves into the history of ponies by assembling a pony genome and integrating horse genomes. This unveils genetic connections between Asian and European pony breeds. Cis‐regulatory elements of key genes impacting body size are also identified.

Calibrating Nonparametric Morphological Indicators from JWST Images for Galaxies over 0.5 < z < 3
The Astrophysical JournalThe measurements of morphological indicators of galaxies are often influenced by a series of observational effects. In this study, we utilize a sample of 832 TNG50 simulated galaxies with log( M _* / M _⊙ )> 9 at 0.5 < z < 3 to investigate the ...

Galaxy peculiar velocities and evolution-bias [PDF]
, 2007 Galaxy bias can be split into two components: a formation-bias based on the locations of galaxy creation, and an evolution-bias that details their subsequent evolution. In this letter we consider evolution-bias in the peaks model.

Structure and Evolution of Regular Galaxies
, 2021 The Thesis is an attempt to combine data from three previously independent areas - the structure and kinematics of stellar populations of the Galaxy, photometric and dynamical models of galaxies, and models of the dynamical and physical evolution of galaxies. This synthesis was made with the goal to understand better the vast topic of the structure and

Photopatternable PEDOT:PSS Hydrogels for High‐Resolution Photolithography
Advanced Science, EarlyView.A photosensitive biphasic conducting polymer hydrogel (PB‐CH) is rationally designed with PEDOT:PSS as the conductive phase and a light‐sensitive matrix as the mechanical phase. Such a PB‐CH offers a unique combination of excellent conductivity (≈30 S cm⁻¹), robust mechanical performance (with stretchability up to 50%), and high photopatternability ...
