Non-Markovian dynamics with fermions
, 2014 Employing the quadratic fermionic Hamiltonians for the collective and internal subsystems with a linear coupling, we studied the role of fermionic statistics on the dynamics of the collective motion.

Statistical property parameterization of simple rocking block response
Earthquake Engineering & Structural Dynamics, 2022 AbstractThe parametric representation of rocking fragilities is statistically investigated. Initially, the potential normalization of the rocking parameters to reduce the problem's dimensionality is tackled by undertaking comparisons both on a single‐record and a sample‐of‐records basis. It is found that the slenderness angle can be normalized out when

60 GHz Blockage Study Using Phased Arrays
, 2017 The millimeter wave (mmWave) frequencies offer the potential for enormous capacity wireless links. However, designing robust communication systems at these frequencies requires that we understand the channel dynamics over both time and space: mmWave ...

Machine learning approach to predict the depression in job sectors in Bangladesh
Current Research in Behavioral Sciences, 2021 Depression is a significant and growing issue that substantially affects an individual's way of life, interrupting typical functioning and blocking viewpoints. At the same time, they may be unaware they are suffering such a problem. This research focuses

Block-relaxation Algorithms in Statistics [PDF]
, 1994 Many algorithms in recent computational statistics are variations on a common theme. In this paper we discuss four such classes of algorithms. Or, more precisely, we discuss a single class of algorithms, and we show how some well-known classes of statistical algorithms fit in this common class.

Resampling methods for spatial regression models under a class of stochastic designs
, 2006 In this paper we consider the problem of bootstrapping a class of spatial regression models when the sampling sites are generated by a (possibly nonuniform) stochastic design and are irregularly spaced.

Exact and approximate results for deposition and annihilation processes on graphs
, 2005 We consider random sequential adsorption processes where the initially empty sites of a graph are irreversibly occupied, in random order, either by monomers which block neighboring sites, or by dimers.

Evaporative Cooling of a Two-Component Degenerate Fermi Gas
, 1999 We derive a quantum theory of evaporative cooling for a degenerate Fermi gas with two constituents and show that the optimum cooling trajectory is influenced significantly by the quantum statistics of the particles.

A stepwise emergence of evolution in the RNA world
FEBS Letters, EarlyView.How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

Breath Analysis in Disease Diagnosis: Methodological Considerations and Applications
Metabolites, 2014 Breath analysis is a promising field with great potential for non-invasive diagnosis of a number of disease states. Analysis of the concentrations of volatile organic compounds (VOCs) in breath with an acceptable accuracy are assessed by means of using ...
