Surrogate‐Optimized Flow‐Guided Miniature Condenser for Rapid Exhaled Glucose Detection
Advanced Materials Technologies, EarlyView.A surrogate‐optimized miniature condenser guides humid exhaled flow toward cold surfaces to accelerate exhaled breath condensate collection. By improving vapor access within a compact footprint, the design increases sample yield. This enables post‐collection enrichment and rapid colorimetric glucose detection from dilute exhaled biomarkers within a 5 ...

Modeling the Radial Color Profile of M31
Open Astronomy, 2003 We present a preliminary study of a fragment of the radial color profile of the spiral galaxy M 31 in terms of 2-D model accounting for internal extinction in the disk. The two stellar population disk model was assumed.

Predictions and Outcomes for the Dynamics of Rotating Galaxies
Galaxies, 2020 A review is given of a priori predictions made for the dynamics of rotating galaxies. One theory—MOND—has had many predictions corroborated by subsequent observations.

DARK MATTER EQUILIBRIA IN GALAXIES AND GALAXY SYSTEMS [PDF]
The Astrophysical Journal, 2009 [abridged] In the dark matter (DM) halos embedding galaxies and galaxy systems the `entropy' K = σ^2 / ρ^{2/3} (a quantity that combines the radial velocity dispersion σwith the density ρ) is found from intensive N-body simulations to follow a powerlaw run K ~ r^α throughout the halos' bulk, with αaround 1.25.

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.

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,

Surface Brightness Plateau in S4G Galaxies
Galaxies, 2020 Using 3.6-μm data from 2112 galaxies, we show that, contrary to widely held expectations of a continuous steep decline, radial surface brightness profiles of galaxies tend to flatten and form extended plateaus beyond 27–28 magAB/arcsec2.

Equipartition Jet Model for the Seyfert 1 Galaxy 3C120 [PDF]
Journal of Astronomy and Space Sciences, 2003 The motion of 3C120 Jet relative to the core is reasonably uniform and the VLBI scale jet connects outwards to a VLA ˜ 100 kpc scale. We measured the jet width variation from the center and found some indication of a power law which indicates the jet ...
