For a given pseudo-Brewster angle phi(pB) of minimum reflectance |r(p)| of p-polarized light at a dielectric-conductor interface, the second-Brewster angle phi(2B) of minimum reflectance ratio |rho|=|r(p)|/|r(s)| of the p and s polarizations is determined for all possible values of the complex relative dielectric function epsilon that lead to the same phi(pB). The difference phi(2B)-phi(pB) is ...

The cloning and complete sequencing of gene 2 from four independently isolated temperature-sensitive mutants in the phage phi 29 DNA polymerase (ts2 mutants) is reported. The results obtained indicate that, in vivo, the mutations only affect the initial steps of the replication process. Interestingly, three of these mutations consist in the single amino acid change Ala to Val at position 492 of...

We study the coupled dark energy model constructed from general conformal transformation in which coefficient of depends on both scalar field and its kinetic term. Under this transformation, action for subclass Degenerate Higher-Order Scalar-Tensor (DHOST) theories is related to Einstein-Hilbert action. The evolution background universe has scaling fixed point corresponds acceleration at late t...

The dynamics of a kink driven by noise is analyzed using the two collective variables of the Rice ansatz: position and width. Starting from a stochastic partial differential equation, with the phi(4) potential in the overdamped limit, the pair of stochastic differential equations for the collective variables are derived without approximation other than the ansatz itself. From the steady state p...

The Honor Society of Phi Kappa Phi is the nation's oldest, largest, and most highly selective all-discipline honor society, with more than three hundred chapters on campuses across the country. The structure and continuity of the organization depend on volunteer faculty and student leaders at each college or university, both for selection and induction of honorees and for our increasing service...

Measurements of the low-shear viscosity eta(o) with a Zimm-Crothers viscometer for dispersions of colloidal hard spheres are reported as a function of volume fraction phi up to 0.56. Nonequilibrium theories based on solutions to the two-particle Smoluchoski equation or ideal mode coupling approximations do not capture the divergence. However, the nonhydrodynamic contribution to the relative vis...

A new London-Eyring-Polanyi-Sato (LEPS) potential energy surface (PES) is used in the O + CH(4) --> OH + CH(3) reaction via the quasiclassical trajectory method (QCT). Comparing with the experiments and the former ab initio calculations, the new LEPS PES describes the actual potential energy surface of the O + CH(4) reaction successfully. The four polarization dependent "generalized" differenti...

This paper presents the results of an electrophoretic survey of approximately 4000 individuals from Hiroshima and Nagasaki for four erythrocyte enzymes: isocitrate dehydrogenase, peptidase A, peptidase B, and phosphohexose isomerase. Also reported are the results for erythrocyte acid phosphatase for a subset of these individuals. The frequencies for the ACPA1 and ACPB1 alleles of the ACP1 locus...

Yukawa interactions of neutrinos with a new light scalar boson $\phi$ can lead to formation stable bound states and systems many ($\nu$-clusters). For allowed values the coupling $y$ mass $m_\phi$, state two would have size larger than $10^{12}$ cm. Bound sub-cm sizes are possible for keV scale sterile $y > 10^{-4}$. $\nu$-clusters we study in detail properties final configurations. If there is...
