Scale Interactions and Galaxy Evolution [PDF]

Astrophysics and Space Science, 2003
To understand galaxies and their evolution, it is necessary to describe how the different scales interact: how the microscopic physics, such as star formation, or the large scale physics, such as galaxy interactions may modify the galaxy global shapes.

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,

When is a Bulge Not a Bulge? Revealing the Satellite Nature of NGC 5474’s Bulge

The Astrophysical Journal
A satellite galaxy of the nearby spiral M101, NGC 5474 has a prominent bulge offset from the kinematic center of the underlying star-forming disk that has gained attention in recent years.

Interactive Tools (IT) in Galaxy

Proceedings of the Conference on Research Data Infrastructure, 2023
Galaxy is a GUI-based scientific data management and analysis platform that aims to expand the target audience of scientific computing to scientists without advanced computer literacy or access to computing infrastructure. During the operation of a typical asynchronous workflow, the interaction of the user triggers a job submission to a hosted ...

Liquid Metal Nanotransformers for Drug‐Resistant Pan‐Cancer Therapy in Patient‐Derived Organoids

Advanced Science, EarlyView.
Pan‐cancer therapies are severely limited in drug‐resistance patients due to genetic mutations and other factors, resulting in poor therapeutic outcomes and constrained clinical benefit. Liquid metal nanotransformers, a new class of shape‐transformable nanomaterials capable of dramatic morphological changes, offer a promising physical strategy to ...

Galaxies Caught in Transition: The Role of Group Environment in Shaping the Mass–Size Relation in the Local Universe

The Astrophysical Journal
The stellar mass–size relation is a sensitive probe of how environment shapes galaxy structure. We analyse this relation in the local Universe for galaxies in compact groups (CGs), low-mass groups ( M _vir ≤ 10 ^13 M _⊙ ), and high-mass groups, comparing

Galaxy Clusters Across the Electromagnetic Spectrum [PDF]

, 2016
Galaxy clusters are the largest gravitationally bound objects in the Universe. From radio to X-ray, we have observed these objects across the electromagnetic spectrum.

A Circuit of Mechanically Regulated Transcription Factors Balances Regenerative and Fibrotic Memory of Mesenchymal Stromal Cells

Advanced Science, EarlyView.
Producing MSCs on rigid culture substrates induces a scar‐making phenotype, jeapordizing therapeutic success. ‘Tissue‐soft’ surfaces prevent MSC fibrogenesis and preserve regenerative traits. An epigenetic network, driven by HOXA11 and SALL1, maintains ‘soft memory’ by keeping chromatin open in relaxed MSCs, promoting anti‐fibrotic programs.

Galaxy Evolution in Compact Groups. III. Structural Analysis of Galaxies and Dynamical State of Non-isolated Compact Groups

The Astrophysical Journal
Compact groups (CGs) of galaxies are dense systems where projected separations are comparable to their optical diameters. A subset—non-isolated CGs—are embedded within major structures. Using multiband S-PLUS data, we analyse galaxies in 122 non-isolated

Seedless One‐Pot Synthesis of Colloidal InAs Quantum Dots Enabling a High‐Accuracy Photoplethysmography Oximeter

Advanced Science, EarlyView.
A real‐time, non‐contact photoplethysmography (PPG) system based on InAs colloidal quantum dots (CQDs) synthesized via a seedless injection synthesis is demonstrated. The measured oxygen saturation shows considerable agreement with commercial PPG devices.
