Seepage behavior assessment of earth-rock dams based on Bayesian network

open access: yesInternational Journal of Distributed Sensor Networks, 2021
Seepage behavior assessment is an important part of the safety operation assessment of earth-rock dams, because of insufficient intelligent analysis of monitoring information, abnormal phenomena or measured values are often ignored or improperly ...

Withdrawn article: Non-local microscopic potentials for calculation of scattering observables of nucleons on deformed nuclei

open access: yesEPJ Web of Conferences, 2017
The above-mentioned article has been accidentally published twice in the same volume. The Publisher and the Editors have therefore decided to remove one of the articles on November 27, 2018.

Towards systematic large scale Quasiparticle Random-Phase Approximation calculations with covariant and chiral interactions [PDF]

open access: yesEPJ Web of Conferences
One of the main methods used to microscopically describe collective states in atomic nuclei is the quasiparticle random-phase approximation (QRPA). However, due to its high computational cost, systematic studies covering the full nuclear chart are rare ...

Dark Matter & Dark Energy from a single scalar field: CMB spectrum and matter transfer function [PDF]

open access: yes, 2007
The dual axion model (DAM), yielding bot DM and DE form a PQ-like scalar field solving the strong CP problem, is known to allow a fair fit of CMB data.

Toroidal diamond anvil cell for detailed measurements under extreme static pressures

open access: yesNature Communications, 2018
Extreme static pressures exceeding a million atmospheres exist in a variety of natural environments, but obtaining such pressures in a laboratory is still a challenge.

Unidirectional spin Hall magnetoresistance in ferromagnet/normal metal bilayers [PDF]

open access: yes, 2015
Magnetoresistive effects are usually invariant upon inversion of the magnetization direction. In noncentrosymmetric conductors, however, nonlinear resistive terms can give rise to a current dependence that is quadratic in the applied voltage and linear ...

Fission description: First steps towards a full resolution of the time-dependent Hill-Wheeler equation

open access: yesEPJ Web of Conferences, 2017
Dynamical description of low energy fission is, in our full microscopic approach, decomposed in two steps. In the first step we generate the Potential Energy Surface (PES) of the compound system we want to describe with the Hartree-Fock-Bogoliubov (HFB ...

Non local microscopic potentials for calculation of scattering observables of nucleons on deformed nuclei

open access: yesEPJ Web of Conferences, 2017
Direct reactions on deformed nuclei such as actinides are best studied with the coupled channel (CC) formalism and a complex coupling scheme. With all significant progress that has been made in describing target nuclei with mean field and beyond ...

Quantum Algorithms for Weighing Matrices and Quadratic Residues [PDF]

open access: yes, 2000
In this article we investigate how we can employ the structure of combinatorial objects like Hadamard matrices and weighing matrices to device new quantum algorithms.
