Programmable Microgel Degradation in Dynamic Granular Hydrogels Guides Extracellular Matrix Assembly During Tissue Repair

Advanced Materials, EarlyView.
This study reports on the chemical modification of hyaluronic acid to create hydrogels with hydrolytic degradability ranging from 2–28 days. Granular hydrogels that undergo timed degradation to increase porosity enhance cell invasion and provisional ECM remodeling in a muscle injury model, leading to reduced fibrosis and improved regeneration ...

A “Wonderful” Reference Dataset of Mira Variables

Galaxies
The conditions in Mira variable atmospheres make them wonderful laboratories to study a variety of stellar physics such as molecule–grain formation, dust production, shock chemistry, stellar winds, mass loss, opacity-driven pulsation, and shocks. We were

”ASYMPTOTIC PARABOLA” FITS FOR SMOOTHING GENERALLY ASYMMETRIC LIGHT CURVES

Odessa Astronomical Publications, 2016
A computer program is introduced, which allows to determine statistically optimal approximation using the "Asymptotic Parabola" fit, or, in other words, the spline consisting of polynomials of order 1,2,1, or two lines ("asymptotes") connected with a ...

A comparison of OH and H2O maser properties of Mira and semiregular variable stars [PDF]

Monthly Notices of the Royal Astronomical Society, 1999
A sample of 17 Miras and nine semiregular variable stars was simultaneously observed in the OH and H2O maser lines with sensitivities of 0.15 and 0.6 Jy, respectively. One new H2O source was detected. Among Miras the H2O maser luminosity is well correlated with the OH maser luminosity.

Conformal Coating and Transfer of 2D Nanomaterials via Dynamic Interface Engineering

Advanced Materials Interfaces, EarlyView.
This review discusses conformal coating and transfer of two‐dimensional (2D) nanomaterials with a focus on dynamic interface engineering. By actively regulating nanosheet transport and interfacial contact during film formation, recent dynamic coating strategies overcome the limitations of conventional passive approaches and enable geometry‐adaptive ...

Mitochondria and Neuromast Tagging With Fluorescent Gallium‐Triapine Analogues: In Cellulo MP FLIM and Zebrafish Live Imaging

Advanced Science, EarlyView.
Fluorescent BODIPY‐conjugated thiosemicarbazone ligands and their Ga(III), In(III), and Fe(III) complexes, inspired by Triapine, are developed as theranostic agents. Multiphoton FLIM and confocal microscopy in cancer cells and zebrafish reveal real‐time uptake, mitochondrial localisation, and whilst spectroscopic assays indicated preserved complex ...

Linear and nonlinear models of Mira variable stars

, 2018
A survey of linear, nonadiabatic models in the Mira instability region of the H-R diagram has been carried out for masses ranging from 0.8 M(,(CIRCLE)) to 2.0 M(,(CIRCLE)), with effective temperatures from 2700 K to 3400 K and luminosities from 1500 L(,(CIRCLE)) to 7000 L(,(CIRCLE)).

Annual parallax and a dimming event of a Mira variable star, FV Bootis [PDF]

Publications of the Astronomical Society of Japan, 2016
Abstract We present the first measurement of the trigonometric parallax of water masers associated with a Mira star, FV Bootis (FV Boo) using VLBI Exploration of Radio Astrometry (VERA). Based on our multi-epoch VERA observations, we derived the parallax to be 0.97 ± 0.06 mas, which corresponds to a distance of $1.03^{+0.07}_{-0.06}$ kpc.

Adult Sex Ratio as a Demographic Feedback Linking Mating Systems, Parental Care, and Evolution

Advanced Science, EarlyView.
Breeding systems are some of the most diverse social behavior, and our team is investigation the evolutionary causes of this diversity. This review summarises our research carried out at the University of Bath. We argue that demographic components of wild populations, especially the adult sex ratio, plays a key role driving breeding system variation ...

From the Light Curves of Long Period Variables to Their Evolution along the Asymptotic Giant Branch

The Astrophysical Journal
A sample of 116 long period variables is studied with the aim to reveal relations between the properties of their light curves and of their evolution along the asymptotic giant branch (AGB).
