The excitation energy of the first excited state in 23AI was determined by the 24Mg(7Li, ‘He) reaction. The state is observed to be at 460 i 60 keV and belongs to the first excited A = 23 isospin quartet. The results are used to compute the coefficients of the isobaric multiplet mass equation. The influence of this state, a resonance in the **Mg(p, y) channel, on the reaction flow in rp-process...

When gaseous mercury is subjected to an electrical discharge, such as in a fluorescent light bulb, street lamp, or laboratory discharge tube, the collisions between the mercury atoms and the electrons are energetic enough to excite one of the 6s electrons to a higher energy state, while the remaining 79 electrons (including the other 6s electron) remain undisturbed. Depending upon which empty s...

We have studied the channel-size dependence of nonequilibrium electrons excited into higher Landau levels in a quantum Hall conductor, by mapping cyclotron emission in Hall bars of different sizes. The images obtained reveal that the spatial evolution of the nonequilibrium electrons with current density significantly depends on the channel width of the Hall bar on a macroscopic scale of several...

Emission lines from transitions between high-energy states of noble-gas atoms (Ne, Ar, Kr, and Xe) and ions (Ar(+), Kr(+), and Xe(+)) formed and excited during single-bubble cavitation in sulfuric acid are reported. The excited states responsible for these emission lines range 8.3 eV (for Xe) to 37.1 eV (for Ar(+)) above the respective ground states. Observation of emission lines allows for ide...

Due to speed fluctuations of unregulated wind turbines, the terminal voltage may increase to dangerously high levels which have been reported to cause capacitor failure at wind farms. In this topic this paper examines a steady state performance analysis of stand-alone double stator induction generator self excited with two independents capacitors banks. An impedance approach based on double thr...

dynamic behavior of the wind-excited-benchmark-building using semi-active electromagnetic friction dampers (saemfds), with modulated homogeneous friction algorithm is presented. the performance of the benchmark building is studied under across wind loads by installing the saemfds with smooth boundary layer semi-active friction (sblsaf) algorithm. the governing equations of motion are solved by ...

We discuss the deletion of a single vertex in a Delaunay tetrahedralization (DT). While some theoretical solutions exist for this problem, the many degeneracies in three dimensions make them impossible to be implemented without the use of extra mechanisms. In this paper, we present an algorithm that uses a sequence of bistellar flips to delete a vertex in a DT, and we present two different mech...

We present a spectral study of the evolution matrix of the totally asymmetric exclusion process on a ring at half filling. The natural symmetries (translation, charge conjugation combined with reflection) predict only two fold degeneracies. However , we have found that degeneracies of higher order also exist and, as the system size increases, higher and higher orders appear. These degeneracies ...

In the geometric realization of a cubical complex without degeneracies, a 2-set, dipaths and dihomotopies may not be combinatorial, i.e., not geometric realizations of combinatorial dipaths and equivalences. When we want to use geometric/topological tools to classify dipaths on the 1-skeleton, combinatorial dipaths, up to dihomotopy, and in particular up to combinatorial dihomotopy, we need tha...

Strong evidence indicates that the spectrum of planar anomalous dimensions of N = 4 super Yang-Mills theory is given asymptotically by Bethe equations. A curious observation is that the Bethe equations for the psu(1, 1|2) subsector lead to very large degeneracies of 2 multiplets, which apparently do not follow from conventional integrable structures. In this article, we explain such degeneracie...
