A Cosmological Framework for the Co-Evolution of Quasars, Supermassive Black Holes, and Elliptical Galaxies: I. Galaxy Mergers & Quasar Activity

open access: yes, 2007
(Abridged) We develop a model for the cosmological role of mergers in the evolution of starbursts, quasars, and spheroidal galaxies. Combining halo mass functions (MFs) with empirical halo occupation models, we calculate where major galaxy-galaxy mergers

Raising the Roof of the World: Intra‐Crustal Asian Mantle Supports the Himalayan‐Tibetan Orogen

open access: yesTectonics, Volume 44, Issue 9, September 2025.
Abstract The Himalayan‐Tibetan orogen formed via the ongoing collision of India and Asia. Its colossal elevations stem from buoyant crustal roots that doubled in thickness during continental collision, widely believed to result from Indian crust under‐thrusting its Asian counterpart and Asian crustal thickening. However, a single crustal layer of up to

Stable isotope analysis reveals individual variations in feeding habits among wild Japanese macaques

open access: yesEcological Research, Volume 40, Issue 4, Page 523-538, July 2025.
In this study, we conducted a dietary analysis using stable isotopes on the Japanese macaque (Macaca fuscata) group on Koshima Island, Japan. As a result, we clarified the variation in isotope ratios at the individual level, and indicated that this variation is affected by attributes such as sex or dominance‐subordinate relationships in this group ...

Seedling emergence of guar (Cyamopsis tetragonoloba L.) genotypes and their growth under irrigation water salinity

open access: yesAgrosystems, Geosciences &Environment, Volume 8, Issue 2, June 2025.
Abstract Salinity and water scarcity are threatening the sustainability of agriculture in the arid regions of the world. There is an urgent need to develop information on suitable crops that can tolerate salinity and drought to ensure the long‐term viability of agriculture in these regions.

Towards Understanding the Nature of Young Detached Binary System HD 350731 [PDF]

open access: yes, 2015
The young binary system HD 350731 is a noteworthy laboratory for studying early-type binaries with similar components. We present here the analysis of differential multi-color photometric and spectroscopic observations for the double-lined detached ...

On Mitigation of the Uncertainty in Nonlinear Matter Clustering for Cosmic Shear Tomography

open access: yes, 2010
We present a new method that deals with the uncertainty in matter-clustering in cosmic shear power spectrum analysis that arises mainly due to poorly understood nonlinear baryonic processes on small-scales.

How do galaxies acquire their mass? [PDF]

open access: yes, 2011
We introduce a toy model that describes (in a single equation) the mass in stars as a function of halo mass and redshift. Our model includes the suppression of gas accretion from gravitational shock heating and AGN jets mainly for M_halo > M_shock ~ 10 ...

Do Not Let the Beginning Trap you! On Inhibition, Associative Creative Chains, and Hopfield Neural Networks

open access: yesThe Journal of Creative Behavior, Volume 59, Issue 2, June 2025.
ABSTRACT Creative thinking stems from the cognitive process that fosters the creation of new ideas and problem‐solving solutions. Artificial intelligence systems and neural network models can reduce the intricacy of understanding creative cognition. For instance, the generation of ideas could be symbolized as patterns of binary code in which clusters ...

Non-LTE Line Formation in the Near-IR: Hot Stars

open access: yes, 2010
Line-formation calculations in the Rayleigh-Jeans tail of the spectral energy distribution are complicated by an amplification of non-LTE effects. For hot stars this can make quantitative modelling of spectral lines in the near-IR challenging.
