the harmful effects of the long-term ocular exposure to cumulative levels of infrared radiation (ir) in glassblowing and foundries have been recognized since the late 19th century. these effects include cataracts, keratitis, and chronic dry eye problems. therefore, infrared radiation measurements are critical and need to be assessed regularly in the industries and workplaces where there are hig...

Koide parameters for both neutrino and mirror neutrino triplets are examined in light of the CMB mirror neutrino correspondence. This note is just to record slightly improved rest mass predictions for the neutrinos. In the 1980s, Koide predicted the τ lepton rest mass using the simple relation √ memμ + √ mμmτ + √ mτme me + mμ + mτ = 1 4 (1) involving the more accurately known electron and muon ...

We develop a stochastic Asymptotic Preserving (s-AP) scheme for the Vlasov-PoissonFokker-Planck (VPFP) system in the high field regime with uncertainty based on the generalized Polynomial Chaos Stochastic Galerkin framework (gPC-SG). We first prove that, for a given electric field with uncertainty, the regularity of initial data in the random space is preserved by the analytical solution at lat...

We investigate whether a recently proposed modulation of the power spectrum of primordial density fluctuations generated through transplankian (maybe stringy) effects during inflation can be observed. We briefly review the mechanism leading to the modulation and apply it to a generic slow-roll scenario of inflation. We then investigate how these primordial modulation effects leave an imprint in...

This paper presents a new numerical method to solve time fractional Fokker-Planck equation. The space dimension is discretized to the Gauss-Lobatto points, then we apply pseudo-spectral successive integration matrix for this dimension. This approach shows that with less number of points, we can approximate the solution with more accuracy. The numerical results of the examples are displayed.

Koide parameters for both neutrino and mirror neutrino triplets are examined in light of the new Planck results, using the CMB mirror neutrino correspondence. This gives improved rest mass predictions for the neutrinos beyond the original fitted values. In the 1980s, Koide predicted the τ lepton rest mass using the simple relation √ memμ + √ mμmτ + √ mτme me + mμ + mτ = 1 4 (1) involving the mo...
