The BIOHLIT information system (IS) for analyzing behavioral and pathomorphological changes in the central nervous system when studying the effect of ionizing radiation on laboratory animals. Information system is being jointly developed by specialists from MLIT and LRB JINR.
The IS is necessary for storing data in a single information space, enhancing the detection of laboratory animals in...
The most complete information about the state of the human cardiovascular system is provided by the analysis of the array of cardiointervals (RR-intervals) of 24-hour holter monitoring (HM).
The most important task of analyzing a large array of HM RR-intervals is the introduction of the main parameters that most adequately reflect the properties of this array. One way to solve this problem is...
During the start-up regime of the IBR-2M power fluctuations appear, which
the AR system dampens. Their origin is not completely clear, however it
is known that the major reactivity sources are from design - respectively
the OPO and DPO reflectors (axial fluctuations towards the active zone and
their relative phase of intersecting each other facing the center of the
active zone).
A...
Yearly nuclide mass data is fitted to improved versions of the Weizsaecker formula. The present attempt at furthering the precision of this endeavour aims to reach beyond just precision, and obtain predictive capability about the "Stability Island" of nuclides. The method is to perform a fit to a recent improved liquid drop model with isotonic shift. The residuals are then fed to a neural...
We present the effect of using the Metropolis-Hastings algorithm for sampling the integrand on the accuracy of calculating the value of the integral. In addition, a hybrid method for sampling the integrand is proposed, in which part of the training sample is generated by applying the Metropolis-Hastings algorithm, and the other part includes points of a uniform grid. Numerical experiments show...
The Spin Physics Detector, a universal facility for studying the nucleon spin structure and other spin-related phenomena with polarized proton and deuteron beams. It will be placed in one of the two interaction points of the NICA collider that is under construction at the Joint Institute for Nuclear Research (Dubna, Russia). The main objective of the proposed experiment is the comprehensive...
