Carbon - containing covering for anchoring breaking nematic microdevices
We demonstrate experimentally, that inresidual atmosphere of scanning electron microscope the nano-scale carbon-containing (hydrocarbon) films by snuff effect can be produced. The micropattern of carbon film including axial-symmetric ones is defined by the e-beam rasteryesBelgorod State Universit
BRST Algebra Quantum Double and Quantization of the Proper Time Cotangent Bundle
The quantum double for the quantized BRST superalgebra is studied. The
corresponding R-matrix is explicitly constucted. The Hopf algebras of the
double form an analytical variety with coordinates described by the canonical
deformation parameters. This provides the possibility to construct the
nontrivial quantization of the proper time supergroup cotangent bundle. The
group-like classical limit for this quantization corresponds to the generic
super Lie bialgebra of the double.Comment: 11 pages, LaTe

On the n=4 Supersymmetry for the FRW Model
In this work we have constructed the n=4 extended local conformal time
supersymmetry for the Friedmann-Robertson-Walker (FRW) cosmological models.
This is based on the superfield construction of the action, which is invariant
under wordline local n=4 supersymmetry with internal symmetry. It is shown that the supersymmetric action
has the form of the localized (or superconformal) version of the action for n=4
supersymmetric quantum mechanics. This superfield procedure provides a well
defined scheme for including supermatter.Comment: 8 pages. Accepted for publication in Phys. Rev
D=3 N=6 superconformal symmetry of AdS_4 x CP^3 superstring
Invariance of the AdS_4 x CP^3 superstring under D=3 N=6 superconformal
symmetry is discussed in the sector described by the OSp(4|6)/(SO(1,3) x U(3))
supercoset sigma-model action presented in the conformal basis for the
osp(4|6)/(so(1,3) x u(3)) Cartan forms. Transformation rules under D=3 N=6
superconformal symmetry for the (10|24)-dimensional 'reduced' AdS_4 x CP^3
superspace coordinates are obtained and used to derive corresponding
world-sheet currents.Comment: LaTeX, 23 pages; v2: presentation refined, typos corrected,

The Theoretical Description for a Sucralose Electrochemical Cathodical Determination over a 9-9´-Diacridyl-modified Electrode
A novel electroanalytical process for sucralose determination has been theoretically suggested. Sucralose is immobilized over an acridine derivative 9-9´-diacridyl, yielding a quaternary salt, which is thereby gradually electrochemically reduced to an N-N´-disubstituted acridone derivative. The correspondent mathematical model has been developed and analyzed by means of linear stability theory and bifurcation analysis, and this analysis has shown the high probability of the oscillatory and monotonic instabilities, due to the double electric layer structure changes during all of the stages of the process. Nevertheless, it also confirms the efficiency of 9-9´-diacridyl-modified electrode for sucralose determination in an electroanalytical system, which may be coupled with a fluorescent indicator.

Hybrid de novo whole-genome assembly and annotation of the model tapeworm Hymenolepis diminuta
Despite the use of Hymenolepis diminuta as a model organism in experimental parasitology, a full genome description has not yet been published. Here we present a hybrid de novo genome assembly based on complementary sequencing technologies and methods. The combination of Illumina pairedend, Illumina mate-pair and Oxford Nanopore Technology reads greatly improved the assembly of the H. diminuta genome. Our results indicate that the hybrid sequencing approach is the method of choice for obtaining high-quality data. The fnal genome assembly is 177Mbp with contig N50 size of 75kbp and a scafold N50 size of 2.3Mbp. We obtained one of the most complete cestode genome assemblies and annotated 15,169 potential protein-coding genes. The obtained data may help explain cestode gene function and better clarify the evolution of its gene families, and thus the adaptive features evolved during millennia of co-evolution with their hosts
A detecção eletroquímica da lidocaína sobre o oxihidróxido de cobalto trivalente. Uma possibilidade teórica a ser avaliada
O comportamento eletroquímico da lidocaína durante a sua eletrooxidação sobre o oxihidróxido de cobalto trivalente em meio levemente básico, realizada para fins eletroanalíticos, foi avaliado do ponto de vista mecanístico matemático. Da análise foi feita uma conclusão acerca do desempenho do CoO(OH) como modificador de elétrodo na eletrooxidação da lidocaína in vivo e in vitro. Foi, outrossim, verificadaa possibilidade da realização das instabilidades oscilatória e monotônica no sistema.The electrochemical behavior of lidocaine during its electrooxidation over trivalent cobalt oxyhydroxide in lightly alkaline medium, realized for electroanalytical purposes, was evaluated from the mechanistic mathematical point of view. From analysis a conclusion has been made of the electroanalytical function of CoO(OH)as an electrode modifier for lidocaine electrooxidation in vivo and in vitro. Also, the possibility of oscillatory and monotonic instabilities has been verified in the system
