Regularization of Toda lattices by Hamiltonian reduction [PDF]
The Toda lattice defined by the Hamiltonian $H={1\over 2} \sum_{i=1}^n p_i^2 + \sum_{i=1}^{n-1} \nu_i e^{q_i-q_{i+1}}$ with $\nu_i\in \{ \pm 1\}$, which exhibits singular (blowing up) solutions if some of the $\nu_i=-1$, can be viewed as the reduced ...

A comparison of mental arithmetic performance in time and frequency domains
The Heisenberg-Gabor uncertainty principle defines the limits of information resolution in both time and frequency domains. The limit of resolution discloses unique properties of a time series by frequency decomposition.

Randomized Tensor Ring Decomposition and Its Application to Large-scale Data Reconstruction
Dimensionality reduction is an essential technique for multi-way large-scale data, i.e., tensor. Tensor ring (TR) decomposition has become popular due to its high representation ability and flexibility.

Domain decomposition and multilevel integration for fermions [PDF]
The numerical computation of many hadronic correlation functions is exceedingly difficult due to the exponentially decreasing signal-to-noise ratio with the distance between source and sink.

Domain Decomposition CN-FDTD with Unsplit-Field PML for Time-Reversed Channel Analysis [PDF]
In this paper, an efficient domain decomposition (DD) technique is introduced into the implicit Crank-Nicolson finite-difference time-domain (CN-FDTD) method to analyze the channel characteristics of time reversal (TR) waves. As an unconditionally stable

Enhanced fertilization effect of a compost obtained from mixed herbs waste inoculated with novel strains of mesophilic bacteria [PDF]
Mixed medicinal plant waste was composted with addition of novel bacterial strains belonging to the genera Streptomyces, Paenybacillus, Bacillus and Hymenobacter. The composting was followed by assessment of chemical and biological parameters including C/

Qubit representation of qudit states: correlations and state reconstruction
A method to establish a qubit decomposition of a general qudit state is presented. This new representation allows a geometrical depiction of any qudit state in the Bloch sphere.

Functional Analysis and Exterior Calculus on Mixed-Dimensional Geometries [PDF]
We are interested in differential forms on mixed-dimensional geometries, in the sense of a domain containing sets of $d$-dimensional manifolds, structured hierarchically so that each $d$-dimensional manifold is contained in the boundary of one or more $d
