Adiabatic nano-focusing of plasmons by sharp metallic grooves: Geometrical optics approach

open access: yes, 2005
In this paper, we demonstrate the possibility of efficient adiabatic nano-focusing of gap plasmons by sharp metallic V-grooves or dielectric wedges covered with metal.

Gibbs measure for the focusing fractional NLS on the torus

open access: yes, 2022
We study the construction of the Gibbs measures for the focusing mass-critical fractional nonlinear Schrödinger equation on the multidimensional torus. We identify the sharp mass threshold for normalizability and nonnormalizability of the focusing Gibbs ...

Selection and focusing of higher-order modes in a CW waveguide terahertz laser

open access: yesВісник Харківського національногоуніверситету імені В.Н. Каразіна. Серія: Радіофізика та електроніка, 2022
Background: The problems of selection and focusing of higher order modes of a dielectric waveguide laser are considered. The proposed and investigated scheme of mode selection in waveguide quasi-optical resonators can be used in the development and ...

Emapalumab for Immune Effector Cell‐Associated Hemophagocytic Lymphohistiocytosis‐Like Syndrome Following CD19‐Directed CAR‐T in Two Patients With B‐ALL: Clinical and Biomarker Correlates

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Immune effector cell‐associated hemophagocytic lymphohistiocytosis‐like syndrome (IEC‐HS) is a life‐threatening hyperinflammatory toxicity distinct from cytokine release syndrome (CRS) and neurotoxicity following chimeric antigen receptor T‐cell (CAR‐T) therapy. In a single‐institution retrospective cohort of pediatric and young adult patients

Characteristics of sharp focusing of vortex Laguerre-Gaussian beams

open access: yesComputer Optics, 2015
We investigate the intensity distribution of sharply focused Laguerre-Gaussian beams in relation to the uniform (linear and circular) polarization of the beam and the order of the vortex phase. It is shown that to the greatest extent the polarization state affects the longitudinal component of the electric vector of the light field. The greatest visual

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Beams with the transverse-only intensity at the focus

open access: yesКомпьютерная оптика
In this work, sharp focusing of vector beams with azimuthal polarization and beams with V-line of polarization uncertainty is simulated numerically using the Richards-Wolf formulas.

The aqueous supramolecular chemistry of crown ethers

open access: yesFrontiers in Chemistry, 2023
This mini-review summarizes the seminal exploration of aqueous supramolecular chemistry of crown ether macrocycles. In history, most research of crown ethers were focusing on their supramolecular chemistry in organic phase or in gas phase.
