We consider both the effect of particle inertia on stochastic Stokes’ drift, and also a related process which could be considered as a crude model of stochastic Stokes’ drift driven by an eddy diffusivity. In the latter, the stochastic forcing is a stable Ornstein–Uhlenbeck process rather than Brownian motion. We show that the eddy Stokes’ drift velocity has a peak at a non-zero value of the co...

Due to increasing demands on wood, recovered wood is becoming more and more important. It is mainly used for energetic purposes and for particle board production. This material was polluted with various chemicals (surface coatings, biocides, concrete residues, etc.) during service life. These chemicals causes difficulties at the end of service life. In order to elucidate presence of inorganic p...

We report an aptamer discovery technology that reproducibly yields higher affinity aptamers in fewer rounds compared to conventional selection. Our method (termed particle display) transforms libraries of solution-phase aptamers into "aptamer particles", each displaying many copies of a single sequence on its surface. We then use fluorescence-activated cell sorting (FACS) to individually measur...

DOI: 10.1002/admt.201700177 organisms. The manipulation of superparamagnetic microparticles, in particular, has a wide range of applications, including magnetic logic;[13] sorting and trapping of magnetically tagged proteins,[14] cells,[15] and microorganisms;[16] microfluidic mixing;[17] magnetoresistive biosensing;[18] immunoassays;[19] and lab-on-a-tube devices.[20] In principle, the manipul...

Single particle reconstruction from cryoelectron microscopy images, though emerging as a powerful means in structural biology, is faced with challenges as applied to asymmetric proteins smaller than megadaltons due to low contrast. Zernike phase plate can improve the contrast by restoring the microscope contrast transfer function. Here, by exploiting simulated Zernike and conventional defocused...

The paper deals with efficiency comparison of two global evolutionary optimization methods implemented in MATLAB. Attention is turned to an elitist Non-dominated Sorting Genetic Algorithm (NSGA-II) and a novel multi-objective Particle Swarm Optimization (PSO). The performance of optimizers is compared on three different test functions and on a cavity resonator synthesis. The microwave resonator...

Connecting different theoretical approaches, curvature modulated sorting in lipid bilayers fixed on non-planar surfaces is investigated. First, we present a continuous model of lateral membrane dynamics, described by a nonlinear PDE of 4th order. We then prove the existence and uniqueness of solutions of the presented model and simulate membrane dynamics using a finite element approach. Adoptin...
