Liver Fat Quantification and Steatosis Grading in Fatty Liver Disease by Magnetic Resonance Imaging: Systematic Review and Meta‐Analysis

open access: yesJournal of Gastroenterology and Hepatology, Volume 40, Issue 12, Page 2808-2819, December 2025.
ABSTRACT Aim Magnetic resonance imaging (MRI) surrogate biomarkers are widely utilized to diagnose and monitor metabolic dysfunction–associated steatotic liver disease (MASLD). This meta‐analysis assesses their effectiveness in quantifying liver fat and grading steatosis.

An omnidirectional shear horizontal wave transducer based on ring array of face-shear (d24) piezoelectric ceramics

open access: yes, 2016
The non-dispersive fundamental shear horizontal (SH0) wave in plate-like structures is of practical importance in non-destructive testing (NDT) and structural health monitoring (SHM).

Late Pleistocene to Holocene sedimentation in the Great Blue Hole (Lighthouse Reef, Belize): Results from a 30 m long core

open access: yesThe Depositional Record, Volume 11, Issue 5, Page 1376-1398, November 2025.
A 30 m long sedimentary succession at the bottom of the Belize Blue Hole represents terrestrial cenote (12.5–7.2 ka BP), restricted marine swamp (7.2–5.7 ka BP) and fully marine lagoonal phases (5.7–0 ka BP) on Lighthouse Reef carbonate platform. Post‐glacial and Holocene sea‐level rise largely controlled the sedimentological, faunal and floral changes

Flow estimation in a steel pipe using guided waves [PDF]

open access: yes, 2016
In this investigation, a flow rate estimation guided wave based scheme in pipes is proposed. The effect of the fluid over the propagation of longitudinal waves has been experimentally studied by using several laminar flows of water transported by a ...

Fish By‐Products Utilization in Food and Health: Extraction Technologies, Bioactive, and Sustainability Challenges

open access: yesFood Science &Nutrition, Volume 13, Issue 11, November 2025.
Fish by‐products, often discarded, are rich sources of bioactive peptides, collagen, and omega‐3s with antioxidant, antihypertensive, and antimicrobial properties. Advanced, sustainable extraction technologies can valorize this waste into functional food, nutraceutical, and biomedical ingredients.

Adhesive joint evaluation by ultrasonic interface and lamb waves [PDF]

open access: yes
Some results on the application of interface and Lamb waves for the study of curing of thin adhesive layers were summarized. In the case of thick substrates (thickness much more than the wave length) the interface waves can be used.

Emerging Nonthermal Technologies for the Production of Postbiotics

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 24, Issue 6, November 2025.
ABSTRACT Postbiotics, defined as nonliving microbial cells and their components that confer health benefits to the host, represent a significant advancement in functional foods and dietary supplements. Compared to probiotics and prebiotics, postbiotics offer advantages in product stability, safety, and formulation flexibility. In general practice, heat
