Equivalent teleparallel theories in diagonalizable spacetimes: Comment on "Metric-affine approach to teleparallel gravity"

open access: yes, 2013
It is well known that the teleparallel equivalent of general relativity yields the same vacuum solutions as general relativity does, which ensures that this particular teleparallel model is in good agreement with experiments. A less known result concerns

Receptor‐like kinases BIR1 and BIR3 modulate antiviral resistance by different mechanisms

open access: yesNew Phytologist, Volume 247, Issue 2, Page 813-829, July 2025.
Summary BRASSINOSTEROID INSENSITIVE1‐ASSOCIATED RECEPTOR KINASE 1 (BAK1)‐INTERACTING RECEPTOR‐LIKE KINASE (BIR) proteins are negative regulators of cell death and defense against microbes in Arabidopsis thaliana. Here, we demonstrate that the members of the BIR family function as negative regulators of antiviral resistance in Arabidopsis.

Using rotation, magnetic activity and lithium to estimate the ages of low mass stars

open access: yes, 2014
The rotation rate, level of magnetic activity and surface lithium abundance are age-dependent quantities in stars of about a solar mass and below. The physical reasons for the evolution of these phenomena are qualitatively understood, but accurate ...

Transcriptional Changes in Cumulus Cells During In Vitro Maturation of Human Oocytes

open access: yesMolecular Reproduction and Development, Volume 92, Issue 6, June 2025.
ABSTRACT This study assessed transcriptional changes in human cumulus cells (CCs) during oocyte maturation In Vitro. CCs were collected from 25 cumulus‐oocyte complexes derived from surplus ovarian medulla tissue of eight women (mean age 29 years, range 19–36) undergoing ovarian tissue cryopreservation without ovarian stimulation.

Majority-vote on directed Small-World networks

open access: yes, 2007
On directed Small-World networks the Majority-vote model with noise is now studied through Monte Carlo simulations. In this model, the order-disorder phase transition of the order parameter is well defined in this system.

Comparison of Ising magnet on directed versus undirected Erdos-Renyi and scale-free network [PDF]

open access: yes, 2006
Scale-free networks are a recently developed approach to model the interactions found in complex natural and man-made systems. Such networks exhibit a power-law distribution of node link (degree) frequencies n(k) in which a small number of highly ...

Hydromechanical Modeling of Fault Rupture in Geologic CO2 Sequestration: A Comparison of Two Failure Criteria

open access: yesGeophysical Research Letters, Volume 52, Issue 10, 28 May 2025.
Abstract The large‐scale implementation of geological carbon sequestration has raised concerns about potential fault activation and induced seismicity, which could compromise storage integrity and pose seismic risks. We theoretically compared two failure criteria, Mohr‐Coulomb (MC) and Modified Cam‐Clay criteria (MCC), to assess fault rupture during ...

ASPECTOS REPRODUTIVOS DE Leporinus piau FOWLER, 1941 (OSTEICHTHYES, ANOSTOMIDAE) DA BACIA DO RIO SÃO FRANCISCO, SUBMETIDO À DESOVA INDUZIDA

open access: yesCiência Animal Brasileira, 2009
Leporinus piau Fowler, 1941, é importante como peixe forrageiro e na pesca da bacia do São Francisco. Fêmeas dessa espécie foram submetidas à desova induzida, mediante a aplicação de duas doses de extrato bruto de hipófise de carpa-comum (EBHC) (0,5 e 5 ...
