Implications for the formation of Oort cloud-like structures and interstellar comets in dense environments

open access: yesAstronomy & Astrophysics
Most stars form in dense stellar environments, where frequent close encounters can strongly perturb and reshape the early architecture of planetary systems.

Fabrication of BaZr0.1Ce0.7Y0.1Yb0.1O3‐δ Skeleton Structure for the Development of High‐Performance Nanocomposite Cathodes for Protonic Ceramic Fuel Cells by Nitrate Impregnation

open access: yesSmall, EarlyView.
A homologous BZCYYb1711 cathode skeleton was constructed using the same material as the electrolyte, and active components were introduced into the skeleton via nitrate impregnation to form a nanocomposite cathode. This strategy effectively alleviated the thermal expansion coefficient (TEC) mismatches between the cathode and electrolyte.

The role of the host—Neutrophil biology

open access: yesPeriodontology 2000, EarlyView., 2023
Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...

Identifying and Characterizing Infrared Excesses in the Spitzer Kepler Survey (SpiKeS)

open access: yesThe Astrophysical Journal
We report our search for infrared excesses in the Spitzer/Infrared Array Camera survey of the Kepler field at 3.6 and 4.5 μ m. The Spitzer Kepler Survey contains ∼190,000 targets, which we reduce to ∼117,000 targets after applying multiple filters to ...

Shear‐Responsive Red Blood Cell Carriers for Targeted Drug Delivery to Constricted Arteries

open access: yesSmall, EarlyView.
Red blood cells are harnessed as mechanoresponsive carriers that exploit the elevated shear stress of stenotic arteries to transiently open membrane pores and release encapsulated therapeutics selectively at sites of arterial narrowing. By coupling vascular hemodynamics with RBC membrane mechanics, a hemodynamically activated platform for localized ...

Sensing‐Integrated Patient‐Derived Tumorspheres Predict Chemotherapeutic Efficacy via Local Extracellular pH Dynamics

open access: yesSmall, EarlyView.
The study introduces a 3D sensing‐integrated platform enabling real‐time, non‐invasive monitoring of pH dynamics in patient‐derived PDAC tumorspheres. It revealed distinct extracellular acidification patterns under FOLFIRINOX, gemcitabine, and paclitaxel, correlating with therapeutic efficacy.

An Episode of Occultation Events in Gaia21bcv

open access: yesThe Astronomical Journal
A previously unremarkable star near the Canis Major OB1/R1 association underwent an episode of multiple deep brightness minima. Light curves based on archival Gaia, Zwicky Transient Facility (ZTF), and NEOWISE data and additional observations from the ...

Recognizing Patterns in Debris Disks

open access: yes, 2009
An extrasolar planet sculpts the famous debris dish around Fomalhaut; probably many other debris disks contain planets that we could locate if only we could better recognize their signatures in the dust that surrounds them. I will describe the latest 3-D

Proximity Proteomics Maps Candidate Cellular Uptake Pathways for Cell‐Derived Nanovesicles

open access: yesSmall Methods, EarlyView.
TurboID‐based dual‐sided proteomics compares mechanically generated cell‐derived nanovesicles with naturally secreted small extracellular vesicles. Vesicle proteomes define candidate interaction signatures, while recipient‐cell proximity labelling identifies exposure‐associated proteins.

A Data-driven Search For Mid-infrared Excesses Among Five Million Main-sequence FGK Stars

open access: yesThe Astronomical Journal
Stellar infrared excesses can indicate various phenomena of interest, from protoplanetary disks to debris disks, or (more speculatively) techno-signatures along the lines of Dyson spheres.
