An improved value for the lifetime of the (anti-)hypertriton has been obtained using the data sample of Pb–Pb collisions at s_NN=5.02 TeV collected by the ALICE experiment at the LHC. The (anti-)hypertriton has been reconstructed via its charged two-body mesonic decay channel and the lifetime has been determined from an exponential fit to the dN/d(ct) spectrum. The measured value, τ=242₋₃₈ ⁺³⁴ (stat.) ± 17 (syst.) ps, is compatible with representative theoretical predictions, thus contributing to the solution of the longstanding hypertriton lifetime puzzle. © 2019 The Author

The paper provides a view of Material Resource Planning implementation. The authors describe the MRP II implementation techniques and define the necessary requirements for its successful implementation. Possible practical implementation doubts are being pointed out on an actual real-world example. Issues can appear especially in the warm-up period of implementation. The rapid grow of inventory levels issue is particularly analyzed by the authors, who point out the inaccuracy in data in the given bills of materials and in particular the production output data provided by the shop floor. The newly implemented MRP II system reacts to these inaccurate data by acquiring more manufacturing material for production, which leads to the grow of inventory levels in a factory.

We report results of systematic analysis of various modes in the flatband lattice, based on the diamond-chain model with the on-site cubic nonlinearity, and its double version with the linear on-site mixing between the two lattice fields. In the single-chain system, a full analysis is presented, first, for the single nonlinear cell, making it possible to find all stationary states, viz., antisymmetric, symmetric, and asymmetric ones, including an exactly investigated symmetry-breaking bifurcation of the subcritical type. In the nonlinear infinite single-component chain, compact localized states (CLSs) are found in an exact form too, as an extension of known compact eigenstates of the linear diamond chain. Their stability is studied by means of analytical and numerical methods, revealing a nontrivial stability boundary. In addition to the CLSs, various species of extended states and exponentially localized lattice solitons of symmetric and asymmetric types are studied too, by means of numerical calculations and variational approximation. As a result, existence and stability areas are identified for these modes. Finally, the linear version of the double diamond chain is solved in an exact form, producing two split flatbands in the system's spectrum. Copyright © 2017, The Authors. All rights reserved.

Divisibility of dynamical maps is visualized by trajectories in the parameter space and analyzed within the framework of collision models. We introduce ultimate completely positive (CP) divisible processes, which lose CP divisibility under infinitesimal perturbations, and characterize Pauli dynamical semigroups exhibiting such a property. We construct collision models with factorized environment particles, which realize additivity and multiplicativity of generators of CP divisible maps. A mixture of dynamical maps is obtained with the help of correlated environment. Mixture of ultimate CP divisible processes is shown to result in a new class of eternal CP indivisible evolutions. We explicitly find collision models leading to weakly and essentially non-Markovian Pauli dynamical maps. Copyright © 2017, The Authors. All rights reserved.

The aim of the study was to determine the influence of the laser processing on the properties of electro-spark coatings. The properties were assessed by analyzing the coating microstructure, X-ray radiation, microhardness, corrosion resistance, porosity and tribological tests. In addition, the paper presents the results of measurements and analysis of electrical pulse during ESD. The tests were carried out on WC-Cu coating (the anode) obtained by electro spark deposition over carbon steel C45 (the cathode) and molten with a laser beam. The coatings were deposited by means of the EIL-8A and they were laser treated with the Nd:YAG. The tests show that the laser-treated electro-spark deposited WC-Cu coatings are characterized by lower hardness and friction force, higher seizure resistance, roughness. The laser treatment process causes the homogenization of the chemical composition, the structure refinement and the healing of microcracks and pores of the electro-spark deposited coatings. Laser treated electro-spark deposited coatings are likely to be applied in sliding friction pairs and as protective coatings.

In this paper we treat the mixed H 2 /H ∞ control problem with the static output feedback, whose feasible solution is difficult to be found theoretically. To this problem we propose an iterative approach based on the idea of the exterior-point approach in the sense that a sequence of controller variables starting from the infeasible region to the feasible one is constructed. One of features of our approach is to be able to update Lyapunov variables and controller variables simultaneously using a partial derivative of the H 2 cost function. The efficiency of our approach is shown by numerical examples.

This paper presents an approach intended for tracking of biological non-stationary signals. The proposed approach utilizes a Kalman filter autoregressive model together with a method for estimation of covariance matrices of the uncorrelated process noise and measurement noise. The method was tested in simulations, where the ability of tracking of a class of time varying autoregressive processes was the subject of our interest. The obtained results are promising in the meaning that the suggested algorithm is suitable to track the time varying autoregressive processes with sufficient accuracy. © 2015 IEEE.
