A 40 Myr Old Gaseous Circumstellar Disk at 49 Ceti: Massive CO-Rich Comet Clouds at Young A-Type Stars

open access: yes, 2012
The gaseous molecular disk that orbits the main sequence A-type star 49 Ceti has been known since 1995, but the stellar age and the origin of the observed carbon monoxide molecules have been unknown.

Key New Evidence for the Hainan Mantle Plume Head: Ongoing Formation of a Large Igneous Province?

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract The process‐based surface magmatic expression of mantle plumes is typically a large igneous province (LIP) induced by the mantle plume head, followed by subsequent age‐progressive volcanic tracks resulting from plate drifting above the plume tail.

Study of the Decay $\Lambda_c \to \Lambda l^+ \nu_{l}

open access: yes, 1994
Using the CLEO II detector at CESR, we observe 500 $\Lambda l^+$ pairs consistent with the semileptonic decay $\Lambda_c \to \Lambda l^+ \nu_{l}$. We measure $\sigma (e^+ e^- \to \Lambda_c X) \dot {cal B}(\Lambda_c^+ \to \Lambda l \nu_{l}) =4.77 \pm 0.25

Bionic Eye: A Glance at the Argus II retinal prosthesis

open access: yesAdvances in Ophthalmology & Visual System, 2015
The Argus II retinal prosthesis is a promising new artificial vision restoration technology that, after years of extensive research, is now being implemented on a commercial basis. It is currently the only retinal implant to be approved by the Food and Drug Administration (FDA), Health Canada, and the Conformite Europeenne.

Impacts of Glacial Isostatic Adjustment on Antarctic Subglacial Water Routing Since the Last Glacial Maximum

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 5, May 2026.
Abstract The bedrock beneath the Antarctic Ice Sheet has experienced widespread viscoelastic deformation as a response to ice‐sheet changes from the Last Glacial Maximum (LGM) to present day. The combined changes of the ice sheet and the bedrock most likely had impacted subglacial water routes.

Comparative Analysis of Heat Exposure‐Induced Molecular Changes in Two Turtle Species with Contrasting Thermal Adaptations

open access: yesIntegrative Zoology, Volume 21, Issue 3, Page 609-623, May 2026.
Protein processing in the endoplasmic reticulum is highlighted in response to heat stress in Platysternon megacephalum. Under heat stress, the up‐regulation of genes such as CHOP in protein processing in the endoplasmic reticulum pathway, along with the suppression of energy and lipid metabolism and the up‐regulation of JARID2 expression, leads to ...

Measurement of partial branching fractions of inclusive charmless B meson decays to K^+, K^0, and π^+ [PDF]

open access: yes, 2011
We present measurements of partial branching fractions of B → K^+X, B → K^0X, and B → π^+X, where X denotes any accessible final state above the endpoint for B decays to charmed mesons, specifically for momenta of the candidate hadron greater than 2.34 ...
