The emission of the airborne particles from epoxy resin test sticks with different CNT loadings and two commercial products were characterized while sanding with three grit sizes and three disc sander speeds. The total number concentrations, respirable mass concentrations, and particle size number/mass distributions of the emitted particles were measured using a condensation particle counter, a...
Tracking the formation and evolution of dark matter haloes is a critical aspect any analysis cosmological $N$-body simulations. In particular, mass assembly halo its progenitors, encapsulated in form merger tree, serves as fundamental input for constructing semi-analytic models galaxy and, more generally, building mock catalogues that emulate surveys. We present an algorithm trees from AbacusSu...
The dependence of the dynamic properties of liquid metals and Lennard-Jones fluids on the characteristics of the interaction potentials is analyzed. Molecular-dynamics simulations of liquids in analogous conditions but assuming that their particles interact either through a Lennard-Jones or a liquid-metal potential were carried out. The Lennard-Jones potentials were chosen so that both the effe...
Cylindrical concrete cores of 10 cm diameter and height were taken from the columns and shear walls of randomly chosen 5-40 years old reinforced concrete (RC) buildings located in different towns of Istanbul and Izmit (Kocaeli) in Turkey from 2000 to date. The ultrasonic pulse velocity (UPV) measurements and uniaxial compressive strength (UCS) tests were conducted on 200 concrete core specimens...
Abstract Direct N -body simulations of a large number particles, especially in the study planetesimal dynamics and planet formation, have been computationally challenging even with modern machines. This work presents combination fully parallelized 2 /2 interactions incorporation GENGA code’s close encounter pair grouping strategy to enable MIMD parallelization Symplectic Massive Body Algorithm ...
We present a versatile approach to produce macroscopic, substrate-supported arrays of plasmonic nanoparticles with well-defined interparticle spacing and a continuous particle size gradient. The arrays thus present a "plasmonic library" of locally noncoupling plasmonic particles of different sizes, which can serve as a platform for future combinatorial screening of size effects. The structures ...
We study an elasticity model for compressed protein monolayers or particle rafts at a liquid interface. Based on the microscopic view of hard-core particles with soft shells, a bead-spring model is formulated and analyzed in terms of continuum elasticity theory. The theory can be applied, for example, to hydrophobin-coated air-water interfaces or, more generally, to liquid interfaces coated wit...
With the increase in energy of the Large Hadron Collider to a centre-of-mass energy of 13 [Formula: see text] for Run 2, events with dense environments, such as in the cores of high-energy jets, became a focus for new physics searches as well as measurements of the Standard Model. These environments are characterized by charged-particle separations of the order of the tracking detectors sensor ...
Microplastic particles, as a second-phase material in ice, may contribute to the effect such particles have on melting and rheological behaviour of glaciers, thus influence future meltwater contribution oceans rising sea levels. Hence, it is utmost importance map understand presence dispersal microplastics global scale. In this work, we identified microplastic snow cores collected remote pristi...
Recent results on supercomputers show that beyond 65K cores, the efficiency of molecular dynamics simulations of interfacial systems decreases significantly. In this paper, we introduce a dynamic cutoff method (DCM) for interfacial systems of arbitrarily large size. The idea consists in adopting a cutoff-based method in which the cutoff is chosen on a particle-by-particle basis, according to th...
