Why are some BL Lacs detected by \fermi, but others not ?

open access: yes, 2014
By cross-correlating an archival sample of 170 BL Lacs with 2 year \fermilat AGN sample, we have compiled a sample of 100 BL Lacs with \fermi detection (FBLs), and a sample of 70 non-\fermi BL Lacs (NFBLs).

Precision Diagnostics in Sports‐Related Traumatic Brain Injury: Pathophysiology, Biomarker Development and Emerging Technologies

open access: yesAdvanced Sensor Research, EarlyView.
Sports‐related traumatic brain injuries (TBIs) remain underdiagnosed, within amateur athletic cohorts. This review critically synthesises recent advancements in AI‐assisted neuroimaging, blood‐based biomarker profiling, wearable biosensing platforms for early detection, injury stratification, and longitudinal surveillance of TBIs.

Single‐Cell Transcriptome Analysis Reveals That Hmga2 Regulates Neuroinflammation and Retinal Function by Modulating Müller Cell Autophagy Through PI3K/AKT Signaling Following MCAO‐Induced Retinal Ischemia

open access: yesAdvanced Science, EarlyView.
Employing snRNA‐seq post‐MCAO‐induced retinal ischemia (RI), this study revealed a novel Hmga2‐high Müller cell subpopulation. Hmga2 knockout alleviated neuroinflammation and RI symptoms, potentially by binding PI3K and regulating Müller cell autophagy.

Lightlike simultaneity, comoving observers and distances in general relativity

open access: yes, 2006
We state a condition for an observer to be comoving with another observer in general relativity, based on the concept of lightlike simultaneity. Taking into account this condition, we study relative velocities, Doppler effect and light aberration.

Single‐Nucleus RNA Sequencing Reveals Mid‐Gestational Neurodevelopment Features in the Superior Temporal Plane from Fetuses with Nonsyndromic Cleft Lip and Palate

open access: yesAdvanced Science, EarlyView.
Single‐nucleus RNA sequencing of mid‐gestation brains from fetuses with nonsyndromic cleft lip and palate reveals major disruptions in cell composition, cell‐to‐cell signaling, and gene regulation. The transcription factor MEF2C is identified as a central regulator of these changes and shows that lowering MEF2C impairs synapse formation, linking cleft ...

Moving Signals and Their Measured Frequencies

open access: yes, 2013
In determining the classical Doppler Effect, two assumptions are used for computing the difference in distance travelled by consecutive signals: (a) the receptor is stationary, and (b) the emitter is stationary.

FMO2 Promotes Angiogenesis via Regulation of N‐Acetylornithine

open access: yesAdvanced Science, EarlyView.
This study identifies flavin‐containing monooxygenase 2 (FMO2) as a novel proangiogenic regulator in endothelial cells. Targeted FMO2 ablation impairs vessel sprouting, whereas its compensation potently enhances angiogenesis. Metabolomics and single‐cell sequencing reveal that FMO2 drives vascular growth via the N‐acetylornithine/ATF3/NOTCH1 axis ...
