Numerical modelling of optical trapping [PDF]

Computer Physics Communications, 2001
Optical trapping is a widely used technique, with many important applications in biology and metrology. Complete modelling of trapping requires calculation of optical forces, primarily a scattering problem, and non-optical forces. The T-matrix method is used to calculate forces acting on spheroidal and cylindrical particles.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

7Li(15N,14C)8Be reaction and 13,14C + 8Be nuclei interactions

Ядерна фізика та енергетика, 2017
Angular distributions of the 7Li(15N,14C)8Be reaction were measured at the energy Elab(15N) = 81 MeV. The reaction data were analyzed within coupled-reaction-channels (CRC) method. The 7Li + 15N elastic and inelastic scattering and the more important one-

Integrable Models of Quantum Optics [PDF]

Bulletin of the Russian Academy of Sciences: Physics, 2017
We give an overview of exactly solvable many-body models of quantum optics. Among them is a system of two-level atoms which interact with photons propagating in a one-dimensional (1D) chiral waveguide; exact eigenstates of this system can be explicitly constructed.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

The Optical Model Absorption Term in the Frame of Fractional Derivatives

Atoms
The complex optical model has been widely used to describe the elastic scattering of the nucleon–nucleus. The imaginary term of the optical potential takes into account the non-elastic scattering processes.

Elastic and inelastic scattering of 18O ions by 6Li at 114 MeV and isotopic differences of 6, 7Li + 18O and 6Li + 16, 18O nuclei interactions [PDF]

Ядерна фізика та енергетика, 2012
Angular distributions of the 6Li + 18O elastic and inelastic scattering as well as the 6Li(18O, Х) reactions with production of 16,17,19O + 8,7,5Li, 14,15,16,17N + 10,9,8,7Be and 12,13,14C + 12,11,10B nuclei were measured at Elab(18O) = = 114 MeV.

Biophysical approaches for studying viral entry

FEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the
