Redshift Surveys and Cosmology

, 1999
Redshift surveys are one of the prime tools of observational cosmology. Imaging surveys of the whole sky are now available at a wide range of wavelengths, and provide a basis for the new generation of massive redshift surveys currently in progress.

Programmed Aggregation of Lipidated Nitrobenzoselenadiazole as a Photo‐Activatable Pyroptosis Inducer

Advanced Healthcare Materials, EarlyView.
This study presents alkylated nitrobenzoselenadiazole (NBSD) photosensitizers that self‐assemble into programmable aggregates, enabling photo‐triggered pyroptosis and enhanced ROS generation. The lead compound, NBSD‐NOc, exhibits superior photodynamic activity, high cellular uptake, and implantable gel compatibility with pH‐responsive release.

Machine Learning–based Photometric Redshifts for Galaxies in the North Ecliptic Pole Wide Field: Catalogs of Spectroscopic and Photometric Redshifts

The Astrophysical Journal Supplement Series
We perform an MMT/Hectospec redshift survey of the North Ecliptic Pole Wide (NEPW) field covering 5.4 deg ^2 and use it to estimate the photometric redshifts for the sources without spectroscopic redshifts. By combining 2572 newly measured redshifts from

Functionalized Reduced Graphene Oxide‐Based Nanocomposite Hydrogels for Enhanced Osteogenesis in Bone Tissue Engineering

Advanced Healthcare Materials, EarlyView.
Charge‐opposed reduced graphene oxide fillers are co‐integrated into biopolymeric nanocomposite scaffolds, synergistically enhance osteogenesis. Multiscale characterization reveals how surface chemistry and porosity dictate ectopic mineral architecture.

A test for the redshift dependence of $$\sigma _8$$ σ 8 using $$f\sigma _8$$ f σ 8 measurements

European Physical Journal C: Particles and Fields
We search for a redshift dependence of $$\sigma _8^0$$ σ 8 0 using 23 growth rate measurements from redshift space distortions and peculiar velocity measurements as a consistency check of $$\Lambda $$ Λ CDM.

Mechanical Reinforced and Self‐healing Hydrogels: Bioprinted Biomimetic Methacrylated Collagen Peptide‐Xanthan Gum Constructs for Ligament Regeneration

Advanced Healthcare Materials, EarlyView.
Readily UV‐curing and self‐healing methacrylated collagen peptide (COPMA) hydrogels are developed with tunable mechanical properties. As the interpenetrating network between COPMA and xanthan gum (XG), COPMA‐XG bioinks show improved mechanical properties, printability, and stability, compared to COPMA or XG.

Antitumoral Efficacy of AuNRs‐Laden ECFCs In Vitro and In Vivo: Decoding the Heat and Rays Combo Treatment in Breast Cancer and Melanoma Cells

Advanced Healthcare Materials, EarlyView.
Endothelial Colony Forming Cells (ECFCs) acted as cellular cyborgs, stealthily transporting gold nanorods (AuNRs) into tumors to enable targeted near‐infrared (NIR) hyperthermia combined with radiotherapy. This approach triggers ferroptosis in melanoma and inhibits autophagy in breast cancer, revealing a tumor‐specific response to nanomaterial‐assisted

Spatially Resolved Modeling of Galactic Hα Emission for Galaxy Clustering

The Astrophysical Journal
Near-infrared spectroscopic surveys target high-redshift emission-line galaxies (ELGs) to probe cosmological scenarios. Understanding the clustering properties of ELGs is essential to derive optimal constraints.

Bilirubin Sensing Using Organic Electrochemical Transistors: Role of Gate Materials and Operational Parameters

Advanced Healthcare Materials, EarlyView.
This study explores PEDOT:PSS‐based OECTs as sensitive bilirubin sensors, revealing that polarizable gate electrodes (Au, Pt, glassy carbon) enable detection while non‐polarizable Ag/AgCl gates suppress response. Operational parameters modulate current direction, suggesting complex interfacial dynamics.
