A Proteochemometric Model for Ligands of the SLC5 Transporter Family

open access: yesArchiv der Pharmazie, Volume 359, Issue 1, January 2026.
A novel proteochemometric model was developed to predict the activity and selectivity of SLC5 family inhibitors. The model's performance was validated using 10‐fold cross‐validation on publicly available datasets achieving Q2 = 0.79 and MSE < 0.32. Detailed analysis of the results enabled the identification of a new, previously unrecognized selectivity‐

Fast large-scale reionization simulations [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2009
We present an efficient method to generate large simulations of the Epoch of Reionization (EoR) without the need for a full 3-dimensional radiative transfer code. Large dark-matter-only simulations are post-processed to produce maps of the redshifted 21cm emission from neutral hydrogen.

The mean free path of hydrogen ionizing photons during the epoch of reionization [PDF]

open access: yes, 2017
We use the Aurora radiation-hydrodynamical simulations to study the mean free path (MFP) for hydrogen ionizing photons during the epoch of reionization. We directly measure the MFP by averaging the distance 1 Ry photons travel before reaching an optical ...

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

open access: yesMolecular 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.

Dust from reionization

open access: yesAstronomy & Astrophysics, 2004
The possibility that population III stars have reionized the Universe at redshifts greater than 6 has recently gained mo- mentum with WMAP polarization results. Here we analyse the role of early dust produced by these stars and ejected into the in- tergalactic medium.

The impact of helium reionization on the structure of the intergalactic medium [PDF]

open access: yes, 2011
We examine the impact of helium reionization on the structure of the intergalactic medium (IGM). We model the reionization using a radiative transfer (RT) code coupled to the combined gravity hydrodynamics code Enzo.

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

open access: yesGeophysical 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 ...

The Impact of Stellar Initial Mass Function on the Epoch of Reionization: Insights from Semi-Analytic Galaxy Modeling

open access: yesUniverse
The adequate choice of stellar initial mass function (IMF) is crucial when studying high-z galaxy formation and the epoch of reionization (EoR) models. We employ the semi-analytical galaxy model L-Galaxies2020 and the dark matter simulation Millennium-II,

Secondary CMB anisotropies in a universe reionized in patches

open access: yes, 1998
In a universe reionized in patches, the Doppler effect from Thomson scattering off free electrons generates secondary cosmic microwave background (CMB) anisotropies.
