Radon emission rate and analysis of its influencing parameters

open access: yesNukleonika, 2016
The geological and structural conditions define the radon situation inside a building. While the geological realities can be specified by the content of radium-226 and the ratio of radon-222 emitted from the ground the structural conditions are defined ...

Two-Step Biometrics Using Electromyogram Signal Based on Convolutional Neural Network-Long Short-Term Memory Networks

open access: yesApplied Sciences, 2021
Electromyogram (EMG) signals cannot be forged and have the advantage of being able to change the registered data as they are characterized by the waveform, which varies depending on the gesture.

Rare synchronous presentation and development of retroperitoneal dedifferentiated liposarcoma and rectal adenocarcinoma

open access: yesHuman Pathology: Case Reports, 2019
Multiple primary malignancies may occur as synchronous or meta-synchronous tumors in 2–17% of patients. Most multiple primary cancers occur in different locations of the same organ or in other organs such as lung, kidney, prostate, and bone.

The multiplets of finite width 0++ mesons and encounters with exotics

open access: yes, 2006
Complex-mass (finite-width) $0^{++}$ nonet and decuplet are investigated by means of exotic commutator method. The hypothesis of vanishing of the exotic commutators leads to the system of master equations (ME).

Airflow Dynamics over a Beach and Foredune System with Large Woody Debris

open access: yesGeosciences, 2018
Airflow dynamics over beach-foredune systems can be complex. Although a great deal is known about the effects of topographic forcing and vegetation cover on wind-field modification, the role of large woody debris (LWD) as a roughness element and modifier
