Spectroscopic Study of Long Period Eclipsing Binary 32 Cygni [PDF]

open access: yesJournal of Astronomy and Space Sciences, 1992
Spectra of the ζAurigae type eclipsing binary system 32 Cygni were taken at the Asiago Observatory. Using the Gaussian fitting method we can estimate the radial velocity and equivalent widths of some metalic lines.

Infusible Extracellular Matrix Biomaterial Enhances Cell‐Specific Pro‐Repair Responses Following Acute Myocardial Infarction

open access: yesAdvanced Healthcare Materials, EarlyView.
We measure the cell‐specific responses of administering infusible ECM (iECM) in acute myocardial infarction (MI) across multiple timepoints. Using single‐nucleus RNA sequencing and spatial transcriptomics, we measure macrophage activation, fibroblast remodeling, increased vascular development, lymphangiogenesis, cardioprotection, and neurogenesis ...

Classification of Periodic Variable Stars from TESS

open access: yesThe Astrophysical Journal Supplement Series
The number of known periodic variable stars has increased rapidly in recent years. As an all-sky transit survey, the Transiting Exoplanet Survey Satellite (TESS) plays an important role in detecting low-amplitude variable stars.

Effective Penetration of the Oxidized Keratin‐Rebonding Materials Into Hair Shafts Based on Charge Conversion

open access: yesAdvanced Healthcare Materials, EarlyView.
We have developed a smart hair‐repair ingredient based on β‐carboxylic acid amide that undergoes negative‐to‐positive charge conversion under mildly acidic conditions. The initial negative charge facilitates deep penetration into the hair fiber, while the subsequent positive charge enables re‐bonding with sulfonate groups in damaged hair keratin.

TIC 322208686: An Eclipsing System with γ Doradus Pulsations and a Third Component on a Wider Orbit

open access: yesThe Astronomical Journal
TIC 322208686 is known to be a detached binary that exhibits two types of variability: pulsation and eclipse. We present the physical properties of the target star using the short-cadence TESS data from sectors 24, 57, and 58, and our echelle spectra ...

Gentamicin‐Loaded Carbonate Apatite with Dual Antibacterial and Osteogenic Functions for Combating Surgical Site Infections

open access: yesAdvanced Healthcare Materials, EarlyView.
A bone substitute with gentamicin physically precipitated onto the surface of carbonate apatite exhibits prompt drug release, high bactericidal activity, and osteogenic capacity. Efficient antibacterial activity mitigates early postoperative neutrophil accumulation, the status of which may serve as a potential parameter for evaluating the antibacterial

Hybrid Scaffolds Decouple Biochemical & Biophysical Regulation of Cell Phenotype

open access: yesAdvanced Healthcare Materials, EarlyView.
Replicating tissue‐specific extracellular matrix is crucial for understanding its role in disease. This work demonstrates independent control over stiffness, composition and 3D collagen architecture using hybrid scaffolds: patterned collagen perfused with defined hydrogels.
