Advanced Materials, EarlyView.Surface co‐functionalization of biodegradable nanofibers with sodium copper chlorophyllin and quaternary ammonium compounds achieves synergistic antimicrobial activity through combined photodynamic and contact‐killing mechanisms. The cationic surface provides humidity‐resistant electrostatic particle capture while maintaining rapid enzymatic ...

Frontiers in Applied Mathematics and StatisticsThis research is devoted to studying a geometric Brownian motion with drift switching driven by a 2 × 2 Markov chain. A discrete-time multiplicative approximation scheme was developed, and its convergence in Skorokhod topology to the continuous-time ...

Frequency–frequency correlations of single-trajectory spectral densities of Gaussian processes
New Journal of Physics, 2022 We investigate the stochastic behavior of the single-trajectory spectral density $S(\omega ,\mathcal{T})$ of several Gaussian stochastic processes, i.e., Brownian motion, the Ornstein–Uhlenbeck process, the Brownian gyrator model and fractional Brownian ...

Interface Dynamics in Biomolecular Condensates by High‐Speed AFM
Advanced Materials Interfaces, EarlyView.High‐speed atomic force microscopy provides nanoscale structural dynamics at the liquid interface of biomolecular condensates, key elements in several cellular pathways. By addressing the challenges of low surface tension and condensate‐induced instabilities, we achieve nanometer spatial and sub‐second temporal resolution, revealing structural ...

Fractional Brownian Motions [PDF]
Acta Physica Polonica B, 2020 Properties of different models of fractional Brownian motions are discussed in detail. We shall collect here several possible ways of introducing and defining various possible fBms, discuss their properties, find how they are similar, and how they differ.

Advanced Photonics Research, Volume 6, Issue 5, May 2025.Microfabrication using nano‐ to micron‐sized blocks has transformative potential for next‐gen electronics, optoelectronics, and materials. Traditional methods are limited by scalability and precision. STIC, a single‐laser system for precise colloid manipulation and immobilization using femtosecond lasers, is introduced that enables efficient 3D ...

Information Transmission Strategies for Self‐Organized Robotic Aggregation
Advanced Robotics Research, EarlyView.In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

Analysis of extremes in the branching Brownian motion [PDF]
, 2022 In my thesis, I study the extremal process of the branching Brownian motion. I am interested in a model in which particles are independent, move in space according to a Brownian motion and branch. To study the extremal process, I first introduce some

Advanced Robotics Research, EarlyView.Fuel‐free Cu2O‐based micromotors functionalized with β‐cyclodextrin actively remove bisphenol A from water under visible light. The cyclodextrin shell captures BPA and enhances micromotor motility, leading to faster degradation and higher overall removal than nonfunctionalized Cu2O and Cu2O@Au.
