Gravitational Influence from Planets on the Measured Rates of Period Change of Pulsating White Dwarfs

The Astrophysical Journal
The measured rates of period change, $\dot{P}$ , in the signals of pulsating white dwarf stars are often interpreted as direct detections of structural changes from secular cooling.

Nanoprecipitation and Drug Delivery with PMTC: Toward Biomedical Application of Polyesters from Radical Ring‐Opening Polymerization

Macromolecular Bioscience, EarlyView.
Homopolyester from Radical Ring‐Opening‐Polymerisation (RROP) have been applied in nanoprecipitation to form nanoparticles for drug delivery. These nanoparticles are stable over various weeks and showed no toxicity. Encapsulated Coumarine has been delivered to cells to show the full potential of these biodegradable delivery systems from RROP.

Five New Sirius-like White Dwarf–Main-sequence Star Systems with MagAO-X

The Astronomical Journal
Most known white dwarfs in multiple systems with main-sequence stars have been discovered with M-type companions, because the white dwarf causes detectable UV excess and bluer colors than expected from a single M star.

Combined Effects of Depression, Fatigue and Cardiovascular Dysfunction on Functional Dependence Over Seven Years in Early Parkinson's Disease

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Parkinson's disease (PD) is associated with both motor and non‐motor symptoms, which collectively impact activities of daily living (ADLs) and contribute to the loss of functional independence. There is a lack of understanding of how non‐motor symptoms drive this loss in independence.

White Dwarfs in Wide Binaries: The Strong Effects of Stellar Evolution and Mass Loss

The Astrophysical Journal
We examine the statistics of main-sequence/main-sequence, main-sequence/white-dwarf, and white-dwarf/white-dwarf wide binaries at 10 ^2.5 –10 ^4 au separations in Gaia data.

“It's just us”: Families' experiences with temporary tube feeding

Nutrition in Clinical Practice, EarlyView.
Abstract Background Children with temporary feeding tubes are discharged home with increasing frequency, yet little is known about how families adapt and manage in their home environment. Whereas the physical side effects of temporary feeding tubes are well documented, the psychosocial impact on families remains underresearched. Understanding families'

Stellar Cycle and Evolution of Polar Spots in an M+WD Binary

The Astrophysical Journal
Stellar activity cycles reveal continuous relaxation and induction of magnetic fields. The activity cycle is typically traced through the observation of cyclic variations in total brightness or Ca H&K emission flux of stars, as well as cyclic variations ...
