A plausible explanation for the contradictory results published by several groups on the dimensionality of the concept of aromaticity is found. We demonstrate that the good linear relationships between the molar diamagnetic exaltation (Λ) and the resonance energy (RE) of heteroaromatic compounds is not fundamental, but only a consequence of the strong correlation of both properties with the mol...

This work is an experimental study of the diamagnetic cavity created by a dense laser-produced plasma ~initially, n lpp /n0@1) expanding into an ambient magnetized background plasma (n052 310 cm) capable of supporting Alfvén waves. The experiments are carried out on the upgraded Large Plasma Device @W. Gekelman, H. Pfister, Z. Lucky, J. Bamber, D. Leneman, and J. Maggs, Rev. Sci. Instrum. 62, 2...

With increasing energy the diamagnetic hydrogen atom undergoes a transition from regular to chaotic classical dynamics, and the closed orbits pass through various cascades of bifurcations. Closed orbit theory allows for the semiclassical calculation of photoabsorption spectra of the diamagnetic hydrogen atom. However, at the bifurcations the closed orbit contributions diverge. The singularities...

The existence of periodic orbit bunches is proven for the diamagnetic Kepler problem. Members of each bunch are reconnected differently at self-encounters in phase space but have nearly equal classical action and stability parameters. Orbits can be grouped already on the level of the symbolic dynamics by application of appropriate reconnection rules to the symbolic code in the ternary alphabet....

Bone loss is a negative balance course especially occurred after long-term space flight for astronauts under weightlessness [1]. Bone remodeling is a dynamic process that requires the coordinated interaction of osteocytes, osteoblasts, and osteoclasts, collaborating in basic multicellular units (BMUs) [2]. Recently,osteocytes are believed to be the mechanosensors of bone, responding to mechanic...

Persistent current and low-field magnetic susceptibility in single-channel normal metal rings threaded by a magnetic flux φ are investigated within the tight-binding framework considering long-range hopping of electrons in the shortest path. The higher order hopping integrals try to reduce the effect of disorder by delocalizing the energy eigenstates, and accordingly, current amplitude in disor...

The coupling of tetrazotised 1,8-diaminonaphthalene with 1,3-dicarbonyl compounds [acetylacetone,methylacetoacetate and acetoacetanilide] yielded a new series of tetradentate ligand systems. Analytical, IR,1H NMR and mass spectral data indicate that the compounds exist in the intramolecularly hydrogen bondeddihydrazone form. Dibasic tetradentate N2O2 coordination of these compounds in their [ML...
