Influence of Cobalt Doping on the Photogenerated Holes in ZnO Nanoparticles

open access: yesphysica status solidi (RRL) – Rapid Research Letters, Volume 18, Issue 3, March 2024.
Doping ZnO nanoparticles with cobalt ions results in the killing of the core‐defect signal (right panel), which in turn inhibits the light‐induced hole releasing implied in methyl radical generation (left panel). The efficient cobalt doping of zinc oxide nanoparticles grown by chemical method, with Co2+ substituting the Zn2+ cations, is proved by ...

Unsolved problem about stability of stochastic difference equations with continuous time and distributed delay

open access: yesModern Stochastics: Theory and Applications
Despite the fact that the theory of stability of continuous-time difference equations has a long history, is well developed and very popular in research, there is a simple and clearly formulated problem about the stability of stochastic difference ...

Deep Imitation Learning for Optimal Trajectory Planning and Initial Condition Optimization for an Unstable Dynamic System

open access: yesAdvanced Intelligent Systems, Volume 6, Issue 1, January 2024.
A deep imitation learning structure is proposed for optimal trajectory planning of an unstable dynamic system. Given the system's initial conditions, the neural networks (NNs) imitate the iterative linear quadratic regulator to generate near‐optimal trajectories. Leveraging on NN gradients, optimizing the system's initial conditions, avoiding obstacles,

La structure et la sémantique des groupes de mots termes physiques de français [PDF]

open access: yes, 2014
The article analyzes the morphology and semantics of binary term-phrases and formation of genericspecies relationships during their creation. We have identified the basic prepositions that complement the characterizing function of the dependent component

Micropolyelectrons as possible sources of the anomalous positron peaks in heavy-ion reactions [PDF]

open access: yes, 1988
We propose that aggregates of electrons and positrons in a small assembly (micropolyelectrons (e{sup +}e{sup {minus}}){sup n}), held together by their own electromagnetic interactions, are probably the sources of the anomalous positron peaks observed in ...

A Torelli theorem for graphs via quasistable divisors

open access: yesForum of Mathematics, Sigma
AbstractThe Torelli theorem establishes that the Jacobian of a smooth projective curve, together with the polarization provided by the theta divisor, fully characterizes the curve. In the case of nodal curves, there exists a concept known as fine compactified Jacobian.

Kwantowa teoria Lee Smolina a recentywizm Józefa Bańki [PDF]

open access: yes, 2004
The author focused on a certain ideological analogy between the views of Lee Smolin and Józef Bańka. The idea that contemporary science is included in the paradigm of quasistability, thus indeterminacy, is the essence of this analogy.

Development of protective coatings to improve high temperature corrosion resistance in chlorine containing environments based on an advanced corrosion risk assessment tool [PDF]

open access: yes, 2009
The presence of chlorine in several areas of chemical industry, as well as in waste incinerators or plastic/polymer decomposition mills, may significantly reduce the life-time of the plant components due to its significant corrosivity potential.
