Massive stars and globular cluster formation [PDF]
Astrophys.J.665:1164-1172,2007, 2007 We first present chemodynamical simulations to investigate how stellar winds of massive stars influence early dynamical and chemical evolution of forming globular clusters (GCs). In our numerical models, GCs form in turbulent,high-density giant molecular clouds (GMCs), which are embedded in a massive dark matter halo at high redshifts. We show how high-

Star-forming Filament Models [PDF]
The Astrophysical Journal, 2017 Abstract New models of star-forming filamentary clouds are presented in order to quantify their properties and to predict their evolution. These 2D axisymmetric models describe filaments that have no core, one low-mass core, and one cluster-forming core.

Error Assumptions on Generalized STAR Model
Journal of Mathematical and Fundamental Sciences, 2017 For GSTAR models, the least squares estimation method is commonly used since errors are assumed be uncorrelated. However, this method is not appropriate when errors are correlated, either in time or spatially.

Predictive modeling of treatment resistant depression using data from STAR*D and an independent clinical study. [PDF]
PLoS ONE, 2018 Identification of risk factors of treatment resistance may be useful to guide treatment selection, avoid inefficient trial-and-error, and improve major depressive disorder (MDD) care.

Converting neutron stars into strange stars: Instanton model [PDF]
International Journal of Modern Physics D, 2014 We calculate the quasiclassical probability to emerge the quantum fluctuation which gives rise to the quark-matter drop with interface propagating as the self-similar spherical detonation wave (DN) in the ambient nuclear matter. For this purpose, we make use of instanton method which is known in the quantum field theory.

Stellar Evolution and Modelling Stars [PDF]
, 2017 In this chapter I give an overall description of the structure and evolution of stars of different masses, and review the main ingredients included in state-of-the-art calculations aiming at reproducing observational features. I give particular emphasis to processes where large uncertainties still exist as they have strong impact on stellar properties ...

Implementing Dust Shielding as a Criteria for Star Formation [PDF]
, 2019 Star formation is observed to be strongly correlated to dense regions of molecular gas. Although the exact nature of the link between star formation and molecular hydrogen is still unclear, some have suggested that shielding of dense gas by dust grains is the key factor enabling the presence of both.

A Comprehensive Calibration Method for a Star Tracker and Gyroscope Units Integrated System
Sensors, 2018 The integration of a star tracker and gyroscope units (GUs) can take full advantage of the benefits of each, and provide continuous and accurate attitude information with a high update rate.

A Competitive Model of (Super)Stars [PDF]
Eastern Economic Journal, 2012 Following Rosen [1981], superstar effects (earnings convex in quality and a few firms reaping a large share of market earnings) occur with imperfect substitution between sellers, low (and possibly declining) marginal cost of output, and marginal cost falling as quality increases. However, markets without such characteristics have superstar effects, and
