Damage cluster distributions in numerical concrete at the mesoscale [PDF]
Physical Review E, 2017 We investigate the size distribution of damage clusters in concrete under uniaxial tension loading conditions. Using the finite-element method, the concrete is modeled at the mesoscale by a random distribution of elastic spherical aggregates within an elastic mortar paste.

Chromatin and the Cellular Response to Particle Radiation-Induced Oxidative and Clustered DNA Damage
Frontiers in Cell and Developmental Biology, 2022 Exposure to environmental ionizing radiation is prevalent, with greatest lifetime doses typically from high Linear Energy Transfer (high-LET) alpha particles via the radioactive decay of radon gas in indoor air.

Molecules, 2021 Different types of DNA lesions forming in close vicinity, create clusters of damaged sites termed as “clustered/complex DNA damage” and they are considered to be a major challenge for DNA repair mechanisms resulting in significant repair delays and ...

Cluster species and cluster size dependence of damage formation by cluster ion impact [PDF]
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2003 Molecular dynamics simulations of Ne, Ar and Xe clusters with various sizes impacting on Si surfaces were performed in order to study damage formation processes. When cluster size ranged from several tens to several thousands and accelerated energy is 20 keV in total, each cluster impact caused surface damage in the shape of a crater.

Xeroderma Pigmentosum Group A Suppresses Mutagenesis Caused by Clustered Oxidative DNA Adducts in the Human Genome. [PDF]
PLoS ONE, 2015 Clustered DNA damage is defined as multiple sites of DNA damage within one or two helical turns of the duplex DNA. This complex damage is often formed by exposure of the genome to ionizing radiation and is difficult to repair. The mutagenic potential and

Case Studies in Construction Materials, 2021 Soils under spacio-temporally clustered events loading are susceptible to soil fatigue as pore pressure dissipates and the soil is unable to recover. This potential for damage from soil fatigue is identified through an induced seismic fatigue equation ...

AUTOMATED BUILDING SEGMENTATION AND DAMAGE ASSESSMENT FROM SATELLITE IMAGES FOR DISASTER RELIEF [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2021 After a natural disaster or humanitarian crisis, rescue forces and relief organisations are dependent on fast, area-wide and accurate information on the damage caused to infrastructure and the situation on the ground. This study focuses on the assessment

Molecules, 2020 Oxidatively generated damage to DNA frequently appears in the human genome as the effect of aerobic metabolism or as the result of exposure to exogenous oxidizing agents, such as ionization radiation.

Biochemical mechanisms and clusters of damage for high-let radiation [PDF]
Advances in Space Research, 1992 Using mechanisms of indirect and direct radiation, a generalized theory has been developed to account for strand break yields by high-LET particles. The major assumptions of this theory are: (i) damage at deoxyribose sites results primarily in strand break formation and (2) damage to bases leads to a variety of base alterations.
