Report of Simulation Investigations (Part Iii): Structural Tendencies, a Growth of Half-Chaotic Open Networks

Authors: Andrzej Gecow
Comments: 81 Pages. In Polish. An English version is expected in a month.

Parts I and II of the Report concern research in autonomous networks of the basis for the statement that life evolves in half-chaos. This part III, the last, completes this research in open networks. The report is a documentation of research, but it was completed after two publications on the occurrence of half-chaos in growing networks and shielding tendencies, which contained a significant part of this information, so it is only mentioned here for completeness and slightly supplemented. The main topic here is the verification of already published structural tendencies, with a newer, much less simplified algorithm. Structural tendencies in the evolution of complex networks are the cause of the classic, though currently controversial due to the lack of a known explanation, regularities in the evolution of ontogenesis. The presented research confirms the earlier theses, although the current picture of these phenomena turns out to be much more complex and requires the indicated further research.

Flat-Band Energy Analysis of the Temperature-Dependent Superconducting Gap for Hydrogenated Graphite Fibers Found from Nonlocal Electrical Conductance Experimental Data

Authors: Nadina Gheorghiu, Charles R. Ebbing, Timothy J. Haugan
Comments: 5 Pages.

Experimental evidence of novel phenomena in hydrogenated graphite fibers is found. An indirect excitonic mechanism is likely leading to a SC state below the temperature Tc = 50 K, where the gap is divergent. Analysis of the gap within the framework provided by the Bardeen-Cooper-Schrieffer (BCS) theory of superconductivity shows that this is a multigap system. The energy gap data can be better explained within the framework of topologically protected flat bands applied to systems in which superconductivity occurs on the surface or at the internal interfaces of the samples. The temperature dependence of the SC gap is linear above 50 K. We use nonlocal differential conductance Gdiff(V) = dI(V)/dV experimental data to show clear evidence of topological phenomena such as interference of chiral asymmetric Andreev edge states and crossed Andreev conversion. Gdiff(V) has a negative part that results from the nonlocal coherence between electron and holes in the Andreev edge states. We conclude that hydrogenated graphite bears the marks of an unconventional high-temperature superconductor (HTSC).

Understanding of MHE Power Generation Patterns by TSC Theory

Authors: Akito Takahashi, Masahiko Hasegawa, Yutaka Mori
Comments: 17 Pages.

The main MHE power generation pattern can be explained by the nuclear energy release of 4H/TSC WS fusion events at T-sites of Ni nano-cores by dynamic 4H cluster formation of 4 protons moved from O-sites under phonon excitations in GMPW (global mesoscopic potential well) of Ni-nano-islands. This is the major process of power (about 20W in our runs). In addition, minor excess power (about 4 W) is considered being continuously released by 4H/TSC WS fusion events at SNHs (sub-nano-holes) on surfaces of Ni-nano-cores. This minor process remains after H/Ni ratio is saturated. We found a method of MHE power re-activation by the RCV (reaction chamber valve) close-to-open method after H/Ni loading ratio becomes nearer to saturation. When RCV is opened, pulse thermal power generation happens by 4H/TSC WS fusions at SNHs, which induces H-gas desorption-burst from T-sites of Ni-nano-cores. This trigger event produces empty T-sites in Ni-nano-cores and slow H-loading to T-sites restarts with relatively large generation of 4H/TSC WS fusion power (10-15 W) for considerably long time (about one day in our trigger-trial runs). This re-activation/trigger process can be repeated in-situ. We succeeded to trigger more than ten times.Prediction by the TSC theory seems working very well. Some brief historical aspects of "cold fusion" or MHE research evolution are of portion in Introduction.
