Vine‐Inspired Soft Robotics: Materials, Actuations, and Emerging Applications

open access: yesAdvanced Science, EarlyView.
Vine‐inspired robots grow from the tip, enabling navigation through confined spaces with minimal disturbance. This Review summarizes material and actuation strategies for vine‐inspired growth, key functions including steering, retraction, attachment, branching, and variable stiffness, and emerging applications spanning medical intervention, confined ...

Large Variations Seen in First Ultraviolet Spectroscopic M33 Dust Extinction Curves

open access: yesThe Astrophysical Journal
Dust extinction curves provide one of the main avenues to understanding the detailed nature of dust grains and accounting for the effects of dust on observations of many astrophysical objects. For the first time, spectroscopic ultraviolet (UV) extinction

Large Interstellar Polarisation Survey

open access: yesAstronomy & Astrophysics
Our understanding of dust in the diffuse interstellar medium remains incomplete with regard to the structure, composition, size distribution, and alignment properties of its grains.

OBSERVATIONAL EVIDENCE OF DUST EVOLUTION IN GALACTIC EXTINCTION CURVES

open access: yesThe Astrophysical Journal, 2014
Although structural and optical properties of hydrogenated amorphous carbons are known to respond to varying physical conditions, most conventional extinction models are basically curve fits with modest predictive power. We compare an evolutionary model of the physical properties of carbonaceous grain mantles with their determination by homogeneously ...

Atmospheric controls on mineral dust emission from the Bodélé Depression, Chad: The role of the low level jet [PDF]

open access: yes, 2005
Atmospheric aerosols play an important though uncertain role in the Earth's climate system. The Bodélé Depression in Chad stands out as the planet's largest source of dust, yet very little is known about the atmospheric circulation that maintain this ...

Disabling COMPASS Promoter Licensing Shifts HDAC‐Inhibited Gastric Cancer Toward Sustained Transcriptional Suppression During Recovery

open access: yesAdvanced Science, EarlyView.
Combined inhibition of the WDR5 WIN pocket and HDAC activity converts SAHA‐induced hyperacetylation into a promoter state with reduced WDR5–COMPASS association and H3K4me3. MYC/E2F‐linked nascent transcription and biosynthetic recovery are suppressed, while apoptosis and senescence‐like features increase, resulting in sustained growth inhibition in ...

Stellar-reddening-based Extinction Maps for Cosmological Applications

open access: yesThe Astrophysical Journal, 2023
Cosmological surveys must correct their observations for the reddening of extragalactic objects by Galactic dust. Existing dust maps, however, have been found to have spatial correlations with the large-scale structure of the Universe.

A Fluorogenic Cysteine‐Tetrapeptide Tagging Strategy for Nonperturbative Protein Labeling and Protein–Ligand Interaction Tracking

open access: yesAdvanced Science, EarlyView.
A compact Phe‐Cys‐Pro‐Phe (FCPF) tag and an environment‐sensitive SBD‐Cl‐derived probe form a sequence‐selective fluorogenic pair for wash‐free live‐cell protein imaging. This minimally perturbing chemistry allows flexible insertion at termini or loops, produces strong fluorescence upon local microenvironment confinement, supports FRET‐assisted ...

UV extinction properties of carina nebular dust [PDF]

open access: yes, 1993
I have performed an analysis of the UV extinction by dust along the line of sight to the young open cluster Tr 16. The observed curves are parameterized in order to extract quantitative information about the structure of the curves.

In Vivo Nb4C3Tx MXene‐Assisted Photothermal Therapy of Melanoma in Mice

open access: yesAdvanced NanoBiomed Research, EarlyView.
Nb4C3Tx MXene converts pulsed 1064 nm irradiation into localized heat, producing concentration‐ and time‐dependent melanoma cell killing in vitro and suppressing tumor growth in mice. Histology reveals extensive tumor damage, macrophage‐associated material clearance, and no detectable persistent deposits in examined visceral organs, supporting Nb4C3Tx ...
