Spontaneous pairing of homologous DNA sequences – a challenging subject in molecular biophysics, often referred to as ‘homology recognition’ – ha s been observed in vitro for several DNA system s a . One of th e se experiments involved liquid crystalline quasi - columnar phases formed by a mixture of two kinds of oligo mer of double stranded DNA . ...

The ratio of branching fractions and the difference in CP asymmetries of the decays B+ → J/ψπ+ and B+ → J/ψK+ are measured using a data sample of pp collisions collected by the LHCb experiment, corresponding to an integrated luminosity of 3 fb−1 at centre-of-mass energies of 7 and 8 TeV. The results are ℬB+→J/ψπ+ℬB+→J/ψK+=3.83±0.03±0.03×10−2,\docum...

We investigate the general dependence of the thermal transport across nanoparticle-fluid interfaces using molecular dynamics computations. We show that the thermal conductance depends strongly both on the wetting characteristics of the nanoparticle-fluid interface and on the nanoparticle size. Strong nanoparticle-fluid interactions, leading to full...
This paper presents the design, development, and application of a laboratory setup for the experimental investigations of gas flow and reactions in a fractured rock. The laboratory facility comprises (i) a high pressure manometric sorption apparatus, where equilibrium and kinetic phenomena of adsorption and desorption can be examined, (ii) a high p...
Ionic liquids can serve as an environmentally-friendly replacement for solvents in emulsions, therefore they are considered suitable to be used as an emulsified medium for various active materials one of which are extractors of metal ions. Increasing the extraction efficiency is considered to be one of the key objectives when working with such extr...
The production cross-section of J/ψ pairs is measured using a data sample of pp collisions collected by the LHCb experiment at a centre-of-mass energy of s√=13 TeV, corresponding to an integrated luminosity of 279 ±11 pb−1. The measurement is performed for J/ψ mesons with a transverse momentum of less than 10 GeV/c in the rapidity range 2.0

A search for the charmless Bs0 → η′ϕ decay is performed using pp collision data collected by the LHCb experiment at centre-of-mass energies of 7 and 8 TeV, corresponding to an integrated luminosity of 3 fb−1. No signal is observed and upper limits on the Bs0 → η′ϕ branching fraction are set to 0.82 × 10−6 at 90% and 1.01 × 10−6 at 95% confidence le...
We report the characterisation of gated optical image intensifiers for fluorescence lifetime imaging (FLIM), evaluating the performance of several different prototypes that culminate in a new design that provides improved spatial resolution conferred b y the addition of a magnetic field to reduce the lateral spread of photoelectrons on their path b...
