Foundation Model‐Enabled Multimodal Deep Learning for Prognostic Prediction in Colorectal Cancer with Incomplete Modalities: A Multi‐Institutional Retrospective Study

Advanced Science, EarlyView.
FLARE, a multimodal AI framework, combines pathology slides, radiology scans, and clinical reports to predict colorectal cancer outcomes, even when some tests are missing. Evaluated retrospectively in 1679 patients from four medical centers, it consistently achieved the best prognostic accuracy and clearly separated high‐ and low‐risk groups.

A Search for Minute-timescale Flares from the Transient AT 2024wpp

The Astrophysical Journal
The AT 2018cow-like fast blue optical transient AT 2022tsd showed a large number of a few-minute-duration, high-luminosity (∼10 ^43 erg s ^−1 ) flares. We present an intensive search for such flares from another 18cow-like event, AT 2024wpp. We have used

VLBI observations of flared optical quasar CGRaBS J0809+5341 [PDF]

Publications of the Astronomical Society of Japan, 2016
Abstract A bright optical flare was detected in the high-redshift (z = 2.133) quasar CGRaBS J0809+5341 on 2014 April 13. The absolute magnitude of the object reached −30.0 during the flare, making it the brightest one (in flaring stage) among all known quasars so far.

Rod‐Shaped Nanotherapeutics Alleviate Rheumatoid Arthritis by Precisely Disrupting Platelet‐Mediated Pathological Crosstalk via a Morphology‐Dependent Manner

Advanced Science, EarlyView.
Owing to the margination effect, rod‐shaped nanoparticles exhibit markedly enhanced co‐localization with endothelial‐adherent platelets (PLTs) under dynamic blood flow. When internalized by PLTs, rod‐shaped PNR@Res inhibit FAK and PI3K/AKT signaling in a morphology‐dependent manner, thereby disrupting their pathological crosstalk with various ...

The Double Tidal Disruption Event AT 2022dbl Implies that at Least Some “Standard” Optical Tidal Disruption Events Are Partial Disruptions

The Astrophysical Journal Letters
Flares produced following the tidal disruption of stars by supermassive black holes can reveal the properties of the otherwise dormant majority of black holes and the physics of accretion.

Properties of serendipitous X-ray flares discovered in XMM-Newton observations

, 2004
We present the results of a search of the XMM-Newton public data archive for stellar X-ray flares. We find eight flaring sources for which we identify 7 optical counterparts.

Loss‐Based Ensemble Generative Adversarial Network Model for Enhancing the Sperm Morphology Classification

Advanced Intelligent Systems, EarlyView.
A loss‐based ensemble generative adversarial network (GAN) framework is proposed to address mode collapse in sperm morphology classification. By integrating spatial augmentation and multiple GAN models, the study enhances synthetic data quality. The Shifted Window Transformer achieves 95.37% accuracy on the HuSHeM dataset, outperforming previous ...

Fine-Grained Monitoring of Gas Flaring in Persian Gulf Countries With Multispectral SDGSAT-1 Nighttime Imagery

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Gas flaring is a major source of greenhouse gas and a waste of nonrenewable resources. Remote sensing is suggested to be a capable proxy to provide independent, reliable, and regular observations on global gas flaring.
