Microfluidic Engineering of Chitosan‐Coated Nanoemulsions for Controlled Release and Stability in Space Pharmaceutics

Advanced Materials Technologies, EarlyView.
Microfluidic engineering enables the fabrication of chitosan‐coated, melatonin‐loaded nanoemulsions with controlled release and enhanced physicochemical stability for space pharmaceutics. Interfacial biopolymer coating modulates droplet behavior under accelerated thermal stress and simulated microgravity.

Introducing the Condor Array Telescope. V. Deep Broad- and Narrowband Imaging Observations of the M81 Group

The Astrophysical Journal Supplement Series
We used the Condor Array Telescope to obtain deep imaging observations through the luminance broadband and He ii 468.6 nm, [O iii ] 500.7 nm, He i 587.5 nm, H α , [N ii ] 658.4 nm, and [S ii ] 671.6 nm narrowband filters of an extended region comprising ...

Radio Diagnostics Of Galaxy Interactions [PDF]

Symposium - International Astronomical Union, 1999
The Hickson Compact Groups (Hickson 1982) are relatively isolated systems of galaxies with projected separations comparable to the diameters of the galaxies themselves and are an ideal laboratory for the study of the effects of interactions on the various properties of galaxies.

A Proof‐of‐Concept Assessment of a Novel Wearable Eyelid Muscle Device: A Pre‐Clinical Animal Cadaver Study for Eyelid Closure Restoration

Advanced Robotics Research, EarlyView.
This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.

Introducing the Condor Array Telescope. VI. Discovery of Extensive Ionized Gaseous Filaments of the Cosmic Web in the Direction of the M81 Group

The Astrophysical Journal
We used the Condor Array Telescope to obtain deep imaging observations through luminance broadband and He ii , [O iii ], He i , H α , [N ii ], and [S ii ] narrowband filters of an extended region of the M81 Group spanning ≈8 × 8 deg ^2 on the sky ...

Solid Harmonic Wavelet Bispectrum for Image Analysis

Advanced Science, EarlyView.
The Solid Harmonic Wavelet Bispectrum (SHWB), a rotation‐ and translation‐invariant descriptor that captures higher‐order (phase) correlations in signals, is introduced. Combining wavelet scattering, bispectral analysis, and group theory, SHWB achieves interpretable, data‐efficient representations and demonstrates competitive performance across texture,

Distribution of Merging and Post-merger Galaxies in Nearby Galaxy Clusters

The Astrophysical Journal
We study the incidence and spatial distribution of galaxies that are currently undergoing gravitational merging (M) or that have signs of being post-merger (PM) in six galaxy clusters (A754, A2399, A2670, A3558, A3562, and A3716) within the redshift ...

An ATP‐Mediated Antibiotic β‐Peptide Nanofiber That Kills Multidrug‐Resistant Bacteria via a Multistage Mechanism

Advanced Science, EarlyView.
The 3K‐AP system forms infinite supramolecular fibrils that undergo controlled degradation into shorter fragments upon enzymatic hydrolysis. Multitechnique imaging reveals a stepwise bacteriolytic mechanism involving bacterial entrapment, disassembly into lethal constructs, and associated extracellular vesicle release, highlighting the dynamic ...

A Physically Motivated Framework to Compare Pair Fractions of Isolated Low- and High-mass Galaxies across Cosmic Time

The Astrophysical Journal
Low-mass galaxy pair fractions are understudied, and it is unclear whether low-mass pair fractions evolve in the same way as more massive systems over cosmic time. In the era of JWST, Roman, and Rubin, selecting galaxy pairs in a self-consistent way will

The EDGE-CALIFA Survey: Spatially Resolved 13CO(1–0) Observations and Variations in 12CO(1–0)/13CO(1–0) in Nearby Galaxies on Kiloparsec Scales

The Astrophysical Journal Supplement Series, 2023
We present ^13 CO( J = 1 → 0) observations for the EDGE-CALIFA survey, which is a mapping survey of 126 nearby galaxies at a typical spatial resolution of 1.5 kpc.
