Geometric and Radiometric Correction of Multibeam Backscatter Derived from Reson 8101 Systems [PDF]

, 2002
A common by-product of multibeam surveys is a measure of the backscattered acoustic intensity from the seafloor. These data are of immense interest to geologists and geoscientists since maps of the acoustic backscatter strength can be used to infer ...

Body mass index and colorectal cancer recurrence and mortality: A nationwide cohort study in Denmark

International Journal of Cancer, EarlyView.
What's New? Obesity may worsen colorectal cancer prognosis, but the existing evidence remains inconclusive. This large nationwide cohort study comprehensively assessed how BMI interacts with demographic, clinical, and socioeconomic factors to influence colorectal cancer prognosis.

The Impact of Energy Storage System Control Parameters on Frequency Regulation Strategies

IEEE Access
The large-scale development of battery energy storage systems (BESS) has enhanced grid flexibility in power systems. From the perspective of power system planners, it is essential to consider the reliability of BESS to ensure stable grid operation amid a

Epidemiological evidence for the role of puberty and immune senescence in Hodgkin lymphoma aetiology from 1992 Danish cases

International Journal of Cancer, EarlyView.
What's New? The understanding of the epidemiological and clinical distinctions between Epstein–Barr virus (EBV)‐positive and EBV‐negative classic Hodgkin lymphoma remains incomplete. Here, the authors generated unique sets of population‐based sex‐ and age‐specific incidence rates of classic Hodgkin lymphoma in Denmark stratified by histological subtype

Nonlinear association of triglyceride‐glucose body mass index with all‐cause mortality in postmenopausal women, a retrospective cohort study: Evidence from the 2001 to 2014 National Health and nutrition examination survey

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Background The triglyceride‐glucose body mass index (TyG‐BMI) is a novel indicator combining an insulin resistance proxy (TyG index) with adiposity. It remains unclear how TyG‐BMI relates to long‐term mortality risk in postmenopausal women, a group prone to metabolic changes after menopause.

PRMT5 Mediates Sepsis‐Associated Lung Injury by Modulating JAK1 Arginine Methylation: A Mechanism Study

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Lung injury is a common complication in critical sepsis. PRMT5 is implicated in endothelial inflammation and lung diseases, but its role in sepsis‐associated lung injury remains unclear. This study collected clinical sepsis samples and detected the mRNA expression of PRMT5.

Multi-objective parameter design and economic analysis of VSG-controlled hybrid energy systems in islanded grids

Frontiers in Energy Research
Photovoltaic (PV) systems offer cost-effective power solutions for outlying islands but often compromise system stability due to reduced inertia. This study introduces a Virtual Synchronous Generator (VSG) control strategy, integrated with Energy Storage
