Eigenvalue tunneling and decay of quenched random network.

Physical review. E

Avetisov V, Hovhannisyan M, Gorsky A, Nechaev S, Tamm M, Valba O.
PMID: 28085382
Phys Rev E. 2016 Dec;94(6):062313. doi: 10.1103/PhysRevE.94.062313. Epub 2016 Dec 22.

We consider the canonical ensemble of N-vertex Erdős-Rényi (ER) random topological graphs with quenched vertex degree, and with fugacity μ for each closed triple of bonds. We claim complete defragmentation of large-N graphs into the collection of [p^{-1}] almost...

Finite plateau in spectral gap of polychromatic constrained random networks.

Physical review. E

Avetisov V, Gorsky A, Nechaev S, Valba O.
PMID: 29347386
Phys Rev E. 2017 Dec;96(6):062309. doi: 10.1103/PhysRevE.96.062309. Epub 2017 Dec 15.

We consider critical behavior in the ensemble of polychromatic Erdős-Rényi networks and regular random graphs, where network vertices are painted in different colors. The links can be randomly removed and added to the network subject to the condition of...

Mechanisms in the reaction of palladium(II)-pi-allyl complexes with aryl halides: evidence for NHC exchange between two palladium complexes.

PMID: 19575424
Chemistry. 2009 Jul 20;15(29):7063-73. doi: 10.1002/chem.200900373.

A detailed experimental and DFT study (PBE level) of the reaction of [Pd(eta(3)-C(3)H(5))(tmiy)(PR(3))]BF(4) (tmiy = tetramethylimidazolin-2-ylidene, PR(3) = phosphane), precursors to monoligated Pd(0) species, with aryl electrophiles yielding 2-arylimidazolium salt is reported. Experiments establish that an autocatalytic ligand transfer...

Can Sn(OCH2CH2NMe2)2 behave as a stannylene? Equatorial-axial isomerism in the tin(II)-iron(0) complex (Me2NCH2CH2O)2Sn-Fe(CO)4.

Dalton Trans. 2007 Aug 28;(32):3489-92. doi: 10.1039/b708513c. Epub 2007 Jul 13.

Equatorial-axial isomerism of the tin(II)-iron(0) complex (Me2NCH2CH2O)2Sn-Fe(CO)4 (), which indicates that the free Sn(OCH2CH2NMe2)2 () ligand can behave as a stannylene, has been revealed and studied by NMR and IR spectroscopy in solution as well as by Raman spectroscopy...

Dual reactivity of N-heterocyclic carbenes towards copper(II) salts.

Dalton transactions (Cambridge, England : 2003)

Kolychev EL, Shuntikov VV, Khrustalev VN, Bush AA, Nechaev MS.
PMID: 21327287
Dalton Trans. 2011 Mar 28;40(12):3074-6. doi: 10.1039/c0dt01630f. Epub 2011 Feb 17.

Complexes of N-heterocyclic carbenes (NHCs) with copper(II) halogenides are unstable. Upon formation, these complexes decompose to give haloamidinium salts. Contrastingly, O-substituted copper(II) NHC complexes are fairly stable. A series of new five-, six- and seven-membered ring NHC complexes of...

A path to practical Solar Pumped Lasers via Radiative Energy Transfer.

Scientific reports

Reusswig PD, Nechayev S, Scherer JM, Hwang GW, Bawendi MG, Baldo MA, Rotschild C.
PMID: 26434400
Sci Rep. 2015 Oct 05;5:14758. doi: 10.1038/srep14758.

The optical conversion of incoherent solar radiation into a bright, coherent laser beam enables the application of nonlinear optics to solar energy conversion and storage. Here, we present an architecture for solar pumped lasers that uses a luminescent solar...

Analysis of paired end Pol II ChIP-seq and short capped RNA-seq in MCF-7 cells.

Genomics data

Scheidegger A, Burkholder A, Abbas A, Zarns K, Samarakkody A, Nechaev S.
PMID: 26229744
Genom Data. 2015 Sep 01;5:263-267. doi: 10.1016/j.gdata.2015.06.021.

While a role of promoter-proximal RNA Polymerase II (Pol II) pausing in regulation of eukaryotic gene expression is implied, the mechanisms and dynamics of this process are poorly understood. We performed genome-wide analysis of short capped RNAs (scRNAs) and...

Proc IEEE Int Conf Escience. 2015 Aug-Sep;2015:429-438. doi: 10.1109/eScience.2015.27.

DNA@Home is a volunteer computing project that aims to use Gibbs Sampling for the identification and location of DNA control signals on full genome-scale datasets. A fault tolerant and asynchronous implementation of Gibbs sampling using the Berkeley Open Infrastructure...

Weak Measurement Enhanced Spin Hall Effect of Light for Particle Displacement Sensing.

Nano letters

Neugebauer M, Nechayev S, Vorndran M, Leuchs G, Banzer P.
PMID: 30537836
Nano Lett. 2019 Jan 09;19(1):422-425. doi: 10.1021/acs.nanolett.8b04219. Epub 2018 Dec 14.

A spherical nanoparticle can scatter tightly focused optical beams in a spin-segmented manner, meaning that the far field of the scattered light exhibits laterally separated left- and right-handed circularly polarized components. This effect, commonly referred to as giant spin...

Glioma-targeted delivery of exosome-encapsulated antisense oligonucleotides using neural stem cells.

Molecular therapy. Nucleic acids

Tropism of neural stem cells (NSCs) to hypoxic tumor areas provides an opportunity for the drug delivery. Here, we demonstrate that NSCs effectively transport antisense oligonucleotides (ASOs) targeting oncogenic and tolerogenic signal transducer and activator of transcription 3 (STAT3)...
