Hubble Space Telescope Photometry of the Dwarf Spheroidal Galaxy ESO 410-G005 [PDF]

, 2000
We present HST WFPC2 imaging of the nearby low-surface-brightness dwarf spheroidal galaxy ESO 410-G005, which has been resolved into stars for the first time. The resulting color-magnitude diagram for about 2500 stars shows a red giant branch branch with

Leptin Aggravates Thoracic Aortic Dissection Through Impairment of Energy Metabolism in Nrip2+ Smooth Muscle Cells

Advanced Science, EarlyView.
Epidemiological data confirm obesity elevates thoracic aortic dissection (TAD) risk. Patient analyses implicate hyperleptinemia, where leptin binding to vascular smooth muscle cell (VSMC) receptors triggers Socs3‐mediated suppression of Stat5a transcriptional activity.

Evolutionary and Observational Properties of Red Giant Acoustic Glitch Signatures

The Astrophysical Journal, 2023
While solar-like oscillations in red giants have been observed at massive scales by the Kepler mission, few features of these oscillation mode frequencies, other than their global properties, have been exploited for stellar characterization.

Asteroseismology of red-clump stars with CoRoT and Kepler [PDF]

, 2009
The availability of asteroseismic constraints for a large number of red giants with CoRoT and in the near future with Kepler, paves the way for detailed studies of populations of galactic-disk red giants.

Re‐Entrant Super‐Repellent Metallic Structures for Robust Anti‐Icing

Advanced Science, EarlyView.
Breakthrough re‐entrant super‐repellent structures engineered on metals demonstrate unprecedented anti‐icing performances: >600 min icing delay, 1.6 kPa ultralow ice adhesion strength, and 100‐cycle deicing durability. Thermodynamic analysis elucidates novel anti‐icing mechanisms and underlying design principles for exceptional ice‐resistance under ...

Repositioning Antimicrobial Peptides Against WHO‐Priority Fungi

Advanced Science, EarlyView.
The growing burden of drug‐resistant fungal infections, driven by pathogens such as Candida auris, Cryptococcus neoformans, and Aspergillus fumigatus, underscores the urgent need for novel antifungal therapies. This review explores antimicrobial peptides as promising agents with membrane‐disruptive activity, immunomodulatory properties, and delivery ...

The Tip of the Red Giant Branch Distance to the Large Magellanic Cloud [PDF]

The Astronomical Journal, 2000
We present the I-band luminosity function of the red giant branch stars in the Large Magellanic Cloud (LMC) using the data from the Magellanic Clouds Photometric Survey (Zaritsky, Harris & Thompson, 1997). Selecting stars in uncrowded, low-extinction regions, a discontinuity in the luminosity function is observed at I_0 = 14.54 mag.

Evolution of the dust mass loss with luminosity along the giant branch of the globular cluster 47 Tuc [PDF]

, 2001
The paper investigates the properties of the dust mass loss in stars populating the giant branch of the globular cluster 47 Tuc, by combining ISOCAM and DENIS data. Raster maps of 5 fields covering areas ranging from 4 x 4 to 15 x 15 arcmin2 at different

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

The Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Revealing the Fate of Exoplanet Systems: Asteroseismic Identification of Host Star in the Red Clump or Red Giant Branch

The Astrophysical Journal Letters
Determining the evolutionary stage of stars is crucial for understanding the evolution of exoplanetary systems. In this context, red giant branch (RGB) and red clump (RC) stars, which formed at stages in the later evolution of stars situated before and ...
