On the magnetism and dynamics of prominence legs hosting tornadoes

open access: yes, 2016
Solar tornadoes are dark vertical filamentary structures observed in the extreme ultraviolet associated with prominence legs and filament barbs. Their true nature and relationship to prominences requires understanding their magnetic structure and dynamic

Gate‐Align‐SED: Semi‐Supervised Sound Event Detection via Adaptive Feature Gating and Cross‐Task Alignment in Situation Awareness

open access: yesAdvanced Intelligent Systems, EarlyView.
Overview of the proposed Gate‐Align‐SED, including two stages of training: (1) Mean‐Teacher SSL Training; and (2) Enhancer Model Training. In complex real‐world environments such as disaster monitoring, effective sound event detection (SED) is often hindered by the presence of noise and limited labeled data.

Cost–benefit analysis of screening programme for diabetic retinopathy in Bulgaria

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aims Late‐diagnosed diabetic retinopathy (DR) is difficult and expensive to treat. Screening programmes can identify the disease early and reduce the costs of its future treatment. This study aims to analyse the cost–benefit of screening programmes for DR.

A Study of the Effects of Tornado Translation on Wind Loading Using a Potential Flow Model

open access: yesFrontiers in Built Environment, 2022
This paper investigates the effects of tornado translation on pressure and overall force experienced by an airfoil subjected to tornado loading and presents a framework to reproduce the flow conditions and effects of a moving tornado.

Cost‐utility analysis of nusinersen–risdiplam switch in patients with spinal muscular atrophy in Croatia: A discrete event simulation model

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Introduction In recent years, the treatment of spinal muscular atrophy (SMA), a rare disease, has significantly progressed, improving patients' survival and overall quality of life. However, current SMA treatments are expensive, and some (nusinersen) are very inconvenient for patients.

Development of Raman Spectroscopy and Machine Learning Methods for Protein Aggregate Quantification: Application to BSA in Chromatographic Processes

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Protein aggregation poses a significant risk to biopharmaceutical product quality, as even minor amounts of oligomeric species can compromise efficacy and safety. Rapid and reliable detection of protein aggregates thus remains a major challenge in biopharmaceutical manufacturing.

Statistical Characteristics of Dabie‐Vortex‐Associated Tornadogenesis During an 18‐Year Period (2006–2023)

open access: yesAtmospheric Science Letters
The Dabie vortex (DBV), a mesoscale system frequently generating severe weather in the Yangtze River Basin, exhibits spatial overlap with tornado‐prone regions, yet its tornadic potential remains unexplored.

Axisymmetric Tornado Simulations with a Semi-Slip Boundary

open access: yesFluids, 2017
The structure of natural tornadoes and simulated analogs are sensitive to the lower boundary condition for friction. Three-dimensional numerical simulations of storms require a choice for turbulence parameterizations and resolution of wind near the lower

A tornado daily impacts simulator for the central and southern United States

open access: yesMeteorological Applications, 2020
In an average year (1979–2016), the United States experiences nearly 1,100 tornadoes, which cause a total of 68 fatalities. Annual fatality rates have decreased since the peak in the 1920s, but there is a concern that they could start to rise again with ...

From fire whirls to blue whirls and combustion with reduced pollution. [PDF]

open access: yes, 2016
Fire whirls are powerful, spinning disasters for people and surroundings when they occur in large urban and wildland fires. Whereas fire whirls have been studied for fire-safety applications, previous research has yet to harness their potential burning ...
