Radial variations of the SFHs of dwarf irregular galaxies [PDF]
Proceedings of the International Astronomical Union, 2011 AbstractThe LITTLE THINGS project† has compiled multi-wavelength data (including VLA hi-line emission maps, GALEX FUV/NUV imagery, UBV, narrow-band Hα, and Spitzer images) for a representative sample of nearby dwarf irregular (dIrr) galaxies. The broadband data are used to constrain the radial variations of the star formation (SF) rate (SFR) averaged ...

Health Science Reports, Volume 9, Issue 5, May 2026.ABSTRACT Background and Aims Nanomaterials are widely produced and used due to their unique physicochemical properties. Adding nano calcium carbonate to Unplasticized PolyVinyl Chloride (UPVC) improves durability and sustainability. Studies have shown that occupational exposure to UPVC powder can affect the health of employees.

The Kaohsiung Journal of Medical Sciences, Volume 42, Issue 5, May 2026.ABSTRACT Hepatocellular carcinoma (HCC) is a heterogeneous malignancy characterized by high mortality rates. This article presents a discussion of the role of ZNF652 in HCC cell proliferation and apoptosis, thereby identifying a new target for HCC treatment. The expression levels of ZNF652, circRHOT1, and SLC38A6 in HCC and healthy cells were analyzed.

Erasure Insertion in RS-Coded SFH MFSK Subjected to Tone Jamming and Rayleigh Fading
, 2007 The achievable performance of Reed Solomon (RS) coded slow frequency hopping (SFH) assisted M-ary frequency shift keying (MFSK) using various erasure insertion (EI) schemes is investigated, when communicating over uncorrelated Rayleigh fading channels in

Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.Underwater compressed‐air blasting is a novel method developed to control invasive sun corals (Tubastraea spp.). The technique removes coral soft tissue without fragmenting colonies, reducing the risk of regeneration and accidental spread. This approach offers a safer and practical tool for managing invasive corals in natural reefs and biofouling ...

Engineered Biopolymer Architectures for Selective Metal Ions Extraction
Advanced Sustainable Systems, Volume 10, Issue 4, April 2026.This review establishes a mechanism‐oriented framework that connects biopolymer chemistry, structural engineering, ligand design, and hydrometallurgical process variables for selective metal‐ion extraction. It analyzes how functional groups, hierarchical architectures, and solution speciation govern adsorption capacity and selectivity in acidic ...
