Using the vehicle of resolving an apparent paradox, a discussion of quantum interference is presented. The understanding of a number of di erent physical phenomena can be uni ed, in this context. These range from the neutral kaon system to massive neutrinos, not to mention quantum beats, Rydberg wave packets, and neutron gravity.

kinetic studies were made of the reactions between triphenylphosphine 1, dialkyl acetylenedicarboxylates 2 in the presence of nh-acid, such as maleimid (as a protic/nucleophilic reagent) 3. to determine the kinetic parameters of the reactions, they were monitored by uv spectrophotometery. the second order fits were automatically drawn and the values of the second order rate constant (k2) were a...

It was first suggested by Heisenberg that the forces between a proton and a neutron are connected with an exchange of charge between the two heavy particles. This exchange nature of the neutron-proton forces is now generally accepted. It would follow from this assumption that in suitable circumstances a proton (neutron) could emit a positively (negatively) charged particle transforming itself i...

A theoretical model is suggested, which describes a decay of low-angle grain boundaries in deformed nanocrystalline materials (NCMs). In the framework of the model, lattice dislocations that form a low-angle boundary are under the action of the forces owing to external (applied) and internal stresses. The balance of the forces causes the critical shear stress at which a low-angle boundary decay...

The neutral Kaon system is used to test the quantum theory of resonance scattering and decay phenomena. The two dimensional LeeOehme-Yang theory with complex Hamiltonian is obtained by truncating the complex basis vector expansion of the exact theory in Rigged Hilbert space. This can be done for K1 and K2 as well as for KS and KL, depending upon whether one chooses the (self-adjoint, semibounde...

Relativistic mean field study of the newly discovered α-decay chain of Abstract The single particle structure of the low lying levels in the nuclei belonging to the newly observed α-decay chain starting from 287 115 has been studied. Relativistic mean field calculation with two forces NL1 and NL3 has been performed in the blocked BCS approximation. Q-values for possible decay have been calculat...

Abstract The NASA K2 mission, salvaged from the hardware failures of Kepler telescope, has continued Kepler’s planet-hunting success. It revealed nearly 500 transiting planets around ecliptic plane, many which are subject further study, and over 1000 additional candidates. Here we present results an ongoing project to follow-up statistically validate new planets, in particular identify promisin...

Light forces acting on radioactive atoms confine them in very dense and cold samples achieving large phase space density. We describe the processes of radioactive atom production, reduction of their velocity and capture. The trapped atoms form excellent sources for the study of atomic parity non-conservation, β decay asymmetry, other weak force processes, and α decay asymmetry.

Robertson and Seymour proved that every graph with sufficiently large treewidth contains a large grid minor. However, the best known bound on the treewidth that forces an l × l grid minor is exponential in l. It is unknown whether polynomial treewidth suffices. We prove a result in this direction. A grid-like-minor of order l in a graph G is a set of paths in Gwhose intersection graph is bipart...

A two-dimensional pore-scale numerical model was developed to evaluate the dynamics of preferential flow paths in porous media caused by bioclogging. The liquid flow and solute transport through the pore network were coupled with a biofilm model including biomass attachment, growth, decay, lysis, and detachment. Blocking of all but one flow path was obtained under constant liquid inlet flow rat...
