We study the low-temperature electrical and thermal conductivity of CoSi Co 1? x M Si alloys (M = Fe, Ni; ? 0.06). Measurements show that Fe decreases at > 0.01 by an order magnitude compared with pure CoSi. It was expected both lattice electronic contributions to would decrease in alloys. However, our experimental results revealed temperatures below 20 K, Fe- Ni-containing is several times lar...

In this paper, the condensation induced by a sub-cooled water injection in circular horizontal pipe with two-phase stratified flow is investigated. The focus of work to review physical models or correlations predicting heat transfer coefficient and assess them against an experimental database. Three experiments, namely COSI, TOPFLOW-PTS UPTF, are consolidated substantial They have different con...

The Compton Spectrometer and Imager (COSI) is a balloon-borne compact telescope designed to survey the 0.2-5 MeV sky. COSI's energy resolution of $\sim$0.2% at 1.8 MeV, single-photon reconstruction, wide field view make it capable studying astrophysical nuclear lines, particularly 1809 keV $\gamma$-ray line from decaying Galactic $^{26}$Al. Most $^{26}$Al originates in massive stars core-collap...

The present study has been carried out to understand the effect of electronic correlations on recently found fermions in CoSi. For which spectral functions bulk and (001) surface CoSi have investigated using DFT + DMFT advanced methodology at T = 100 K with without inclusion spin–orbit coupling (SOC). Co $${d_{xz}}$$ $${d_{yz}}$$ $$d_{z^2}$$ bands seem contribute threefold degenerate $$\Gamma $...

Trans [1] is a Lisp system at the Space Telescope Science Institute (STScI) which is a key part of the proposal preparation ground system for the Hubble Space Telescope (HST). It was originally developed in the late ‘80s using a mixture of procedural, and blackboard architectures. While the original application met its requirements and performed well for a number of years, the increasing comple...

We show that there is p 0 > 0 and p 1 ; : : :; p N non-negative integers, such that 0 p(x) = p 0 + p 1 cos x + + p N cos Nx and p 0 s 1=3 for s = P N j=0 p j , improving on a result of Odlyzko who showed the existence of such a polynomial p that satisses p 0 (s log s) 1=3. Our result implies an improvement of the best known estimate for a problem of Erdd os and Szekeres. As our method is non-co...
