New Cooperative Mechanisms of Low Energy Nuclear Reactions Using Superlow Energy External Fields
We proposed a new mechanism of LENR: cooperative processes in whole system -
nuclei+atoms+condensed matter can occur at smaller threshold then corresponding
ones on free constituents. The cooperative processes can be induced and
enhanced by low energy external fields. The excess heat is the emission of
internal energy and transmutations at LENR are the result of redistribution
inner energy of whole system.Comment:
On the problem of synthesis of superheavy nuclei. A short historical review on first theoretical predictions and new experimental reality
It is shown that it is just Dubna that possesses the priority both in the
recent synthesis of a superheavy nucleus with charge Z = 114 (Flerov Laboratory
of Nuclear Reactions, JINR) and in its theoretical prediction (Bogoliubov
Laboratory of Theoretical Physics, JINR) made 33 years ago. Possible sizes of
the island of stability of superheavy nuclei are discussed.Comment: LaTeX, 6 page
Synthesis of Superheavy elements and Theory of Atomic Nucleus
The connection of synthesis of long-lived superheavy nuclei and existence of
the island of stability with the choice of realistic nuclear potential is
discussed: the behaviour of the average field of nuclei is an important element
of nuclear models. It is also shown that it is just Dubna that possesses the
priority both in the recent synthesis of a superheavy nucleus with charge Z=114
and in its theoretical prediction made 35 years ago. Possible sizes of the
island of stability of superheavy nuclei are considered.Comment: 14 pages . Talk at the Intern.Symp.on Exotic Nuclei . Baikal Lake,

MicroRNA as therapeutic targets for neuroblastomas
Neuroblastoma is one of the most common extracranial solid tumors in children. One of the main causes of death from childhood cancer in children aged one to five years, and it accounts for about 15% of all deaths from cancer in children. They have characteristic features, such as an early age of onset, a high frequency of metastasis in the diagnosis of patients older than 1 year and a tendency to spontaneous regression of tumors in young children. Although several prognostic factors were identified (age, stage, histology, heredity), identifying non-invasive biomarkers for disease surveillance and monitoring therapy is indeed still a clinical necessity. In this review, we describe the latest miRNA data in neuroblastoma, with an emphasis on those involved in tumor progression, metastasis, and drug resistance. In addition, we will discuss their potential use in the treatment of this tumor
Calculation of the properties of the rotational bands of Gd
We reexamine the long-standing problem of the microscopic derivation of a
particle-core coupling model. We base our research on the Klein-Kerman
approach, as amended by D\"onau and Frauendorf. We describe the formalism to
calculate energy spectra and transition strengths in some detail. We apply our
formalism to the rotational nuclei Gd, where recent experimental
data requires an explanation. We find no clear evidence of a need for Coriolis
attenuation.Comment: 27 pages, 13 uuencoded postscript figures. Uses epsf.st
