A Search for Collisions and Planet–Disk Interactions in the Beta Pictoris Disk with 26 Years of High-precision HST/STIS Imaging

open access: yesThe Astrophysical Journal
β Pictoris's well-studied debris disk and two known giant planets, in combination with the stability of the Hubble Space Telescope’s Space Telescope Imaging Spectrograph (HST/STIS) (and now also JWST), offers a unique opportunity to test planet–disk ...

Sticking of Fine Particles in High-velocity Impact: Application to Size Distribution of Dust Grains in a Debris Disk

open access: yesThe Astrophysical Journal, 2023
Impact experiments were conducted at a velocity of ∼0.2–1.0 km s ^−1 using fine particles with several microns or submicrons in size. For metal (Cu) plate targets, as observed in previous impact experiments using projectiles with sizes larger than tens ...

NEW DEBRIS DISKS IN NEARBY YOUNG MOVING GROUPS [PDF]

open access: yes, 2016
A significant fraction of nearby young moving group members harbor circumstellar debris dust disks. Due to their proximity and youth, these disks are attractive targets for studying the early evolution of debris dust and planetesimal belts.

Proteins, Processing, and Properties of Adhesive Fluid Condensates Purified from Mussels

open access: yesAdvanced Functional Materials, EarlyView.
Mussels exhibit an unmatched proficiency for adhering to wet surfaces in salty environments—a remarkable ability that could inspire new biomedical and technical glues. The fluid protein condensates used to form the underwater mussel glue are extracted, reconstituted and characterized with advanced spectroscopy and nanomechanical analysis, revealing ...

Massive Debris Disks May Hinder Secular Stirring by Planetary Companions: An Analytic Proof of Concept

open access: yesThe Astrophysical Journal
Debris disks or exo-Kuiper belts, detected through their thermal or scattered emission from their dusty components, are ubiquitous around main-sequence stars.

Engineering Cortical Networks: An Open Platform for Controlled Human Circuit Formation and Synaptic Analysis In Vitro

open access: yesAdvanced Healthcare Materials, EarlyView.
An advanced on‐chip cortical network platform merges human stem cell‐derived neurons with microfabricated devices, enabling precise large‐format circuit design, optogenetic control, and molecular dissection of synaptic formation. This innovative system offers a powerful new tool to explore and model brain connectivity, disease mechanisms, can serve as ...

Porous dust grains in debris disks [PDF]

open access: yes, 2013
When modeling the density and grain size distribution in debris disks, the minimum particle size is often significantly larger than the corresponding blowout size.

THE FAINTEST WISE DEBRIS DISKS: ENHANCED METHODS FOR DETECTION AND VERIFICATION [PDF]

open access: yes, 2016
In an earlier study, we reported nearly 100 previously unknown dusty debris disks around Hipparcos main-sequence stars within 75 pc by selecting stars with excesses in individual WISE colors.

Biologically Active Implants Prevent Mortality in a Mouse Sepsis Model

open access: yesAdvanced Healthcare Materials, EarlyView.
A modular, triple‐action titanium implant is developed to prevent implant‐associated infections by repelling bacteria, killing pathogens, and enhancing tissue integration. Coatings with phage cocktails targeting P. aeruginosa and S. aureus show significant bacterial reduction and improved survival in a mouse sepsis model.

A search for debris disks in the Herschel-ATLAS [PDF]

open access: yes, 2010
Aims. We aim to demonstrate that the Herschel-ATLAS (H-ATLAS) is suitable for a blind and unbiased survey for debris disks by identifying candidate debris disks associated with main sequence stars in the initial science demonstration field of the survey.
