Special Issue: XVI Baikal International School-Seminar <<Optimization Methods and Their Applications>>

This volume of the Journal of Global Optimization consists of the papers presented at XVI Baikal International School-Seminar «OptimizationMethods and Their Applications»,which took place on June 30th–July 6th, 2014, on Olkhon Island, Lake Baikal, Russia. Baikal School-Seminars have been held every three years at different places around the lake, since 1969, and we hope that this tradition will be continued. The initiator and organizer of the first twelve School-Seminars was an expert in global optimization, professor Valerian P. Bulatov. Starting in 1989 the School-Seminars became International. XVI School-Seminar was dedicated to the 75th anniversary of professor Oleg V. Vasiliev (1939–2002) awell knownand recognized specialist in optimal control and optimization.XVI School-Seminar attracted 94 participants from 10 countries. The scientific program contained plenary lectures and papers presented at 5 sections: optimal control, discrete optimization, continuous optimization, equilibrium and bilevel programming and optimization methods in inverse problems. We would like to express our gratitude to all authors of the presented papers as well as reviewers for their expertise and comments. We are also very thankful to the following institutes and organizations for their valuable support: Melentiev Energy System Institute, Siberian Branch of the Russian Academy of Sciences, Irkutsk; Laboratory of Algorithms and Technologies for Network Analysis of National Research University «Higher School of Economics», Nizhny Novgorod; Irkutsk State University; Russian Foundation for Basic Research.

Dynamic nuclear polarization and relaxation of H and D atoms in solid mixtures of hydrogen isotopes

We report on a study of Dynamic Nuclear Polarization and electron and nuclearspin relaxation of atomic hydrogen and deuterium in solid molecular matrices ofH$_{2}$, D$_{2}$, and HD mixtures. The electron and nuclear spin relaxationtimes ($T_{1e}$ and $T_{1N}$) were measured within the temperature range0.15-2.5$\,$K in a magnetic field of 4.6 T, conditions which ensure a highpolarization of electron spins. We found that $T_{1e}$ is nearly temperatureindependent in this temperature range, while $T_{1N}$ decreased by 2 orders ofmagnitude. Such strong temperature dependence is typical for the nuclear Orbachmechanism of relaxation via the electron spins. We found that the nuclear spinsof H atoms in solid D$_{2}$ and D$_{2}:$HD can be efficiently polarized by theOverhauser effect. Pumping the forbidden transitions of H atoms also leads toDNP, with the efficiency strongly dependent on the concentration of D atoms.This behaviour indicates the Cross effect mechanism of the DNP and nuclearrelaxation, which turns out to be well resolved in the conditions of ourexperiments. Efficient DNP of H atoms was also observed when pumping the middleD line located in center of the ESR spectrum. This phenomenon can be explainedin terms of clusters or pairs of H atoms with strong exchange interaction.These clusters have partially allowed transitions in the center of the ESRspectrum and DNP may be created via the resolved Cross effect.

Anisotropic Superconducting Gaps and Boson Mode in FeSe 1−x S x Single Crystals

Scanning tunneling spectroscopy has been used to investigate the superconducting gaps of FeSe 1â\u88\u92xSx single crystals and to reveal signatures of a bosonic mode in the quasiparticle density of states. We find that both superconducting gaps residing on different pockets of the Fermi surface are anisotropic. Moreover, the bosonic mode appears in the quasiparticle density of states as a redistribution of states at energy Ω/e, measured with respect to the superconducting gap. The energy of the boson mode Ω is found to scale with the superconducting gap, and it can be estimated to be in the range 2.6 ÷ 3.8 meV in agreement with a recent observation of a resonance spin excitation in neutron scattering. This suggests that quasiparticle interactions with this mode are important for superconductivity

Datasets for next-generation sequencing of DNA and RNA from urine and plasma of patients with prostate cancer

Current prostate cancer (PCa) diagnostic tests suffer from insufficient sensitivity and specificity. Novel biomarkers that can be detected by minimally invasive methods are of a particular value. Here we provide two datasets. The first one is on the whole transcriptome profiling by RNA-seq of urine and plasma obtained from patients with PCa and benign prostatic hyperplasia (BPH). The second one represents targeted sequencing of DNA from urine and plasma of patients with PCa and BPH. Both datasets are available at NCBI Sequence Read Archive under Accession No. SRP093707 and No. SRP093842 respectively.

Study of doubly strange systems using stored antiprotons

Bound nuclear systems with two units of strangeness are still poorly known despite their importance for many strong interaction phenomena. Stored antiprotons beams in the GeV range represent an unp ...

Towards the Fradkin-Vasiliev formalism in three dimensions

In this paper we show that using frame-like gauge invariant formulation forthe massive bosonic and fermionic fields in three dimensions the freeLagrangians for these fields can be rewritten in the explicitly gauge invariantform in terms of the appropriately chosen set of gauge invariant objects. Thisin turn opens the possibility to apply the Fradkin-Vasiliev formalism to theinvestigation of possible interactions of such fields.

Conserved higher-spin charges in AdS 4

Gauge invariant conserved conformal currents built from massless fields of all spins in 4d Minkowski space–time and AdS4 are described in the unfolded dynamics approach. The current cohomology associated with non-zero conserved charges is found. The resulting list of charges is shown to match the space of parameters of the conformal higher-spin symmetry algebra in four dimensions
