Early Results from GLASS-JWST. XXV. Electron Density in the Interstellar Medium at 0.7 ≲ z ≲ 9.3 with NIRSpec High-resolution Spectroscopy

open access: yesThe Astrophysical Journal Letters
The electron density ( n _e ) of the interstellar medium (ISM) in star-forming galaxies is intimately linked to star formation and ionization condition.

Regulation by the Transcriptional Regulator YdcI in E. coli and (p)ppGpp‐Dependent Activation of ydcI Expression

open access: yesMolecular Microbiology, EarlyView.
YdcI, a LysR‐type transcription regulator in Escherichia coli, regulates loci like iraP and mqo. Its expression is induced by (p)ppGpp under stress conditions, and protein levels rise during mid‐exponential growth, connecting its role to stress response and metabolism control. ABSTRACT YdcI, a LysR‐type transcription regulator, has been associated with

Quasar Negative Feedback to Surrounding Galaxies Probed with Lyα Emitters and Continuum-selected Galaxies

open access: yesThe Astrophysical Journal Letters
We report on the statistical analysis of quasar photoevaporation at z  ∼ 2.2 by comparing the density of surrounding Ly α emitters (LAEs) and continuum-selected galaxies, based on the imaging data of the Hyper Suprime-Cam (HSC) Subaru Strategic Program ...

Nature's Complexity Alive: Farewell to Several Unificatory Cosmological Arguments for Monism

open access: yesNoûs, EarlyView.
ABSTRACT Throughout history, numerous thinkers have claimed that monism—in the form of priority monism, existence monism, monotheistic monism, or versions that posit an extra‐cosmic ultimate being—theoretically surpasses pluralism, above all by positing a unified universe.

A C‐repeat binding factor–salicylic acid (CBF–SA) module links wound‐induced evaporative cooling to tissue repair in plants

open access: yesNew Phytologist, EarlyView.
A model of the C‐repeat binding factor–salicylic acid (CBF–SA) module in plant wound healing. Summary Repairing damaged tissues is essential for the survival of all organisms. In plants, tissue injury rapidly triggers defense and repair programs. However, the molecular mechanisms linking early injury cues to the later stage of wound repair remain ...

Warm dark matter model of galaxy formation

open access: yes, 2001
Cold Dark Matter (CDM) models of galaxy formation had been remarkably successful to explain a number of observations in the past decade. However, with both the theoretical modeling and the observations being improved, CDM models have been very recently ...

Optical Spectroscopy of Dwarf Galaxies at z ∼ 0.15 in the COSMOS Field: Star Formation and Dust Properties

open access: yesThe Astrophysical Journal
We present a spectroscopic study of low-mass galaxies (LMGs;10 ^8 ≤ M _* / M _⊙ ≤ 10 ^9 ) at z  ∼ 0.15 in the Cosmic Evolution Survey field, and compare it to a control sample of intermediate-mass galaxies (IMGs; 10 ^9 ≤ M _* / M _⊙ ≤ 10 ^10 ) at z  ∼ 0 ...

Harnessing Bulk‐Segregant Mapping to Identify Trait‐Associated Genes in the Allopolyploid Model Plant Nicotiana benthamiana

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Forward genetics has been instrumental in identifying genes underlying desirable traits, yet its application to polyploid plants, many of which are key agricultural crops, remains challenging due to their genomic complexity. Therefore, we developed BenthMap, a bulk segregant analysis platform for high‐throughput trait mapping and gene ...

Bright galaxy number counts [PDF]

open access: yes, 1995
The value of a plot of galaxy number counts per unit area of sky against magnitude as a probe of the early universe is well known, being influenced by both the curvature of expanding space and the deceleration parameter.
