The Hubble Space Telescope Survey of M31 Satellite Galaxies. II. The Star Formation Histories of Ultrafaint Dwarf Galaxies

The Astrophysical Journal, 2023
We present the lifetime star formation histories (SFHs) for six ultrafaint dwarf (UFD; M _V > − 7.0, $4.9\lt {\mathrm{log}}_{10}({M}_{* }(z=0)/{M}_{\odot })\lt 5.5$ ) satellite galaxies of M31 based on deep color–magnitude diagrams constructed from ...

Update and ADMET Profile of the Latin American Natural Product Database: LANaPDB

Molecular Informatics, Volume 44, Issue 11-12, November‐December 2025.
LANaPDB was updated with 1,164 nonduplicate new compounds coming from Argentina and Panama. Moreover, 41 ADMET (absorption, distribution, metabolism, excretion, and toxicity)‐related parameters were determined, and the results were compared with the Universal Natural Products Database and the approved small‐molecule drugs.

The Effect of Absorption Systems on Cosmic Reionization [PDF]

, 2012
We use large-scale simulations to investigate the morphology of reionization during the final, overlap phase. Our method uses an efficient three-dimensional smoothing technique which takes into account the finite mean free path due to absorption systems,

Cutoff and Emergence of Dart Leaders in an Unbranched Positive Leader Simulation

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Channel cutoff is the process by which an active lightning channel cools down, goes dark, and loses its ability to effectively conduct electricity. Current cutoff precedes several lightning phenomena, notably dart leaders and return strokes, but the process by which a hot, highly‐conducting leader channel can undergo current cutoff is poorly ...

Asking Fast Radio Bursts for More than Reionization History

The Astrophysical Journal
We propose different estimators to probe the intergalactic medium (IGM) during the epoch of reionization (EoR) using the dispersion measure (DM) of the fast radio bursts. We consider three different reionization histories, which we can distinguish with a

The Imprint of Cosmic Reionization on Galaxy Clustering

, 2007
We consider the effect of reionization on the clustering properties of galaxy samples at intermediate redshifts (z~0.3-5.5). Current models for the reionization of intergalactic hydrogen predict that overdense regions will be reionized early, thus ...

Therapeutic Implications of Biomolecular Corona on Lipid Nanoparticle‐Based Gene Delivery Systems

Small Science, Volume 5, Issue 9, September 2025.
This image illustrates the role of the biomolecular corona in lipid nanoparticles (LNPs), highlighting its impact on the stability, immune response, biodistribution, and targeted delivery. Formed after injection, the corona influences how LNPs circulate, interact with the cells, and modulate the immune response.

Deep Space Network Radio Science and Ground‐Based Planetary Radar in the Next Decade

Radio Science, Volume 60, Issue 7, July 2025.
Abstract The Deep Space Network (DSN) has been a core operational element of NASA's crewed and robotic exploration of the Solar System since the early 1960s. The primary role of the DSN has been to acquire telemetry and navigation data, but over the years, its radiometric and radar capabilities have expanded to form a system for obtaining unique ...

Recent Advances in Cosmological Hydrogen Reionization

, 2012
I discuss recent advances in the study of hydrogen reionization, focusing on progress that was achieved during the years 2010-2011. First, I discuss recent measurements of the progress of reionization.

MAYA (Multiple ActivitY Analyzer): An Open Access Tool to Explore Structure‐Multiple Activity Relationships in the Chemical Universe

Molecular Informatics, Volume 44, Issue 2, February 2025.
MAYA is an open chemical multiverse visualizer tool for the automated exploration of structure‐multiple activity relationships (SMARts). Abstract Herein, we introduce MAYA (Multiple Activity Analyzer), a tool designed to automatically construct a chemical multiverse, generating multiple visualizations of chemical spaces of a compound data set described
