The slip correction factor has been investigated at reduced pressures and high Knudsen number using polystyrene latex (PSL) particles. Nano-differential mobility analyzers (NDMA) were used in determining the slip correction factor by measuring the electrical mobility of 100.7 nm, 269 nm, and 19.90 nm particles as a function of pressure. The aerosol was generated via electrospray to avoid multip...

Abstract. We consider a system of particles experiencing diffusion and mean field interaction, and study its behaviour when the number of particles goes to infinity. We derive non-asymptotic large deviation bounds measuring the concentration of the empirical measure of the paths of the particles around its limit. The method is based on a coupling argument, strong integrability estimates on the ...

background and aims: inhibition of viral growth in coinfected cells with two different viruses has been described. this phenomenon known as viral interference can occur in several virus host systems such as interference of enterovirus infection on poliovirus vaccine strains. in this study we superinfected reovirus infected hela cells with poliovirus to determine if poliovirus can replicate in s...

By using observables that only depend on charged particles (tracks), one can efficiently suppress pileup contamination at the LHC. Such measurements are not infrared safe in perturbation theory, so any calculation of track-based observables must account for hadronization effects. We develop a formalism to perform these calculations in QCD, by matching partonic cross sections onto new nonperturb...

background: nano-particles are extensively employed in most industries. several studies have been started to explore the probable detrimental effects of nano-particles on human reproduction. however, there is insufficient and controversially evident of effects of silver nano-particles on sperm parameters and other reproductive indices. objective: investigation of the effects of silver nano-part...

ABSTRACT The masses of compact objects in X-ray binaries are best constrained through dynamical measurements, relying on radial velocity curves the companion star. In anticipation upcoming high spectral resolution telescopes, we explore their potential to constrain mass function object. Fe K line fluorescence is a common feature spectra luminous binaries, with Doppler-broadened component from i...

A new method to measure the trace elemental composition of size-resolved airborne particles that uses acetone extraction followed by ICPMS analysis is compared to three other established methods: copper anode XRF, molybdenum anode XRF, and an ICPMS method that uses HF digestion. The method detection limit (MDL), accuracy, and precision of each method is studied through the analysis of ambient s...
