Machine Learning for Exoplanet Detection: A Comparative Analysis using Kepler Data [PDF]
Iranian Journal of Astronomy and AstrophysicsThe discovery of exoplanets has expanded our understanding of planetary systems and opened new avenues for astronomical research. In this study, we present a machine learning (ML) framework for exoplanet identification using a time-series photometric ...

FEBS Letters, EarlyView.Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

MODELING THE LIGHT CURVE OF THE TRANSIENT SCP06F6 [PDF]
The Astrophysical Journal, 2009 We consider simple models based on core collapse or pair-formation supernovae to account for the light curve of the transient SCP06F6. A radioactive decay diffusion model provides estimates of the mass of the required radioactive nickel and the ejecta as functions of the unknown redshift.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
FEBS Letters, EarlyView.Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

The Light Curve Epochs of Supernovae Explosions [PDF]
International Astronomical Union Colloquium, 1980 AbstractA brief description of the current state of knowledge for Type II light curves is given, including discussion of some of the remaining problems. The use of supernovae of both types as independent distance indicators is outlined and difficulties are pointed out. A summary of new ideas regarding the origin of Type I light curves is presented.

FEBS Letters, EarlyView.Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Photometrıc Observatıons of Symbıotıc Star AG PEG
East European Journal of PhysicsIn the article, using the AAVSO (American Association of Variable Star Observers) photometric database of the AG Pegasi symbiotic star, a light curve was constructed in the Vis filter for a period of 68 (1954-2022) years.
