Probing the deuteron structure at small N-N distances by cumulative pion production [PDF]

open access: yesThe European Physical Journal A, 2003
The fragmentation of deuterons into pions emitted forward in the kinematic region forbidden for free nucleon-nucleon collisions is analyzed. It is shown that the inclusion of the non-nucleonic degrees of freedom in a deuteron results in a satisfactory description of the data for the inclusive pion spectrum and improves the description of the data about

Energy-Sensitive and "Classical-like" Distances Between Quantum States [PDF]

open access: yes, 1998
We introduce the concept of the ``polarized'' distance, which distinguishes the orthogonal states with different energies. We also give new inequalities for the known Hilbert-Schmidt distance between neighbouring states and express this distance in terms

On the distance energy of k-uniform hypergraphs

open access: yesSpecial Matrices, 2023
In this article, we extend the concept of distance energy for hypergraphs. We first establish a relation between the distance energy and the distance spectral radius.

Monophonic Distance Laplacian Energy of Transformation Graphs Sn^++-,Sn^{+-+},Sn^{+++}

open access: yesRatio Mathematica, 2023
Let $G$ be a simple connected graph of order $n$, $v_{i}$ its vertex. Let $\delta^{L}_{1}, \delta^{L}_{2}, \ldots, \delta^{L}_{n}$ be the eigenvalues of the distance Laplacian matrix $D^{L}$ of $G$. The distance Laplacian energy is denoted by $LE_{D}(G)$.

An IoT-Based Traceability System for Greenhouse Seedling Crops

open access: yesIEEE Access, 2018
This paper presents the design of the Internet of Things (IoT)-based greenhouse traceability model for the tracking and recordkeeping of seedlings and other agricultural products in the germination and growth stages. Traced products are generally of high

A Statistically and Numerically Efficient Independence Test Based on Random Projections and Distance Covariance

open access: yesFrontiers in Applied Mathematics and Statistics, 2022
Testing for independence plays a fundamental role in many statistical techniques. Among the nonparametric approaches, the distance-based methods (such as the distance correlation-based hypotheses testing for independence) have many advantages, compared ...
