Groups and Protocluster Candidates in the CLAUDS and HSC-SSP Joint Deep Surveys

The Astrophysical Journal, 2022
Using the extended halo-based group finder developed by Yang et al., which is able to deal with galaxies via spectroscopic and photometric redshifts simultaneously, we construct galaxy group and candidate protocluster catalogs in a wide redshift range (0

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.

The Fate of the Milky Way–Andromeda System: To Merge or Not?

The Astrophysical Journal Letters
It has long been predicted that the Milky Way (MW) will eventually merge with Andromeda (M31), a view reinforced by Hubble Space Telescope measurements indicating a small M31 transverse velocity. However, using updated Gaia-based proper motions (PMs) and

The Centaurus Group and the Outer Halo of NGC 5128: Are they Dynamically Connected? [PDF]

, 2006
NGC 5128, a giant elliptical galaxy only $\sim 4$ Mpc away, is the dominant member of a galaxy group of over 80 probable members. The Centaurus group provides an excellent sample for a kinematic comparison between the halo of NGC 5128 and its surrounding

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.

Galaxy groups in the 2dF galaxy redshift survey: Large Scale Structure with Groups

, 2003
We use the 2dF Galaxy Group Catalogue constructed by Merch\'an & Zandivarez to study the large scale structure of the Universe traced by galaxy groups. We concentrate on the computation of the power spectrum and the two point correlation function.

The Geography of Success: A Spatial Analysis of Export Intensity in the Italian Wine Industry

Agribusiness, EarlyView.
ABSTRACT This paper investigates the paradox of how Italy's fragmented, SME‐dominated wine industry achieves global export success. Moving beyond purely firm‐centric explanations, we test whether export intensity is spatially dependent, clustering geographically in regional ecosystems.

Dwarf galaxies in the Dynamically Evolved NGC 1407 Group

, 2006
The NGC 1407 Group stands out among nearby structures by its properties that suggest it is massive and evolved. It shares properties with entities that have been called fossil groups: the 1.4 magnitude differential between the dominant elliptical galaxy ...
