Experimental demonstration of an indoor visible light positioning system using RGB LEDs for multi‐cell networks

The Journal of Engineering
A visible light positioning (VLP) system for multi‐cell networks based on multi‐colour LED that combines frequency division multiplexing with the received signal strength and a trilateration method is proposed. First, it employs experimental measurements

Peptide‐Ligand Cooperative Interplay Drives Gold Nanoparticle Encapsulation by Protein Cages

Small, EarlyView.
Gold nanoparticle encapsulation within protein cages is governed by salt‐dependent binding energetics and cooperative peptide–ligand interactions. Ligands enhance electrostatic attraction while peptides extend recruitment and prevent kinetic trapping, enabling robust cargo loading. This molecular‐level insight links experiments and simulations, guiding

Beyond Starch: Towards a Scalable Potato Platform for Molecular Farming

Plant Biotechnology Journal, EarlyView.
Re‐engineering potato as a biosafe and host‐optimised platform for plant molecular farming by integrating intrinsic biological traits with targeted engineering strategies. ABSTRACT Thirty‐five years after the first recombinant protein was produced in potato and 30 years after clinical trials of edible vaccines from its tubers, the crop is being ...

CONCERT: A Modular Reconfigurable Robot for Construction

Journal of Field Robotics, Volume 43, Issue 3, Page 1332-1362, May 2026.
ABSTRACT This paper presents CONCERT, a fully reconfigurable modular collaborative robot (cobot) for multiple on‐site operations in a construction site. CONCERT has been designed to support human activities in construction sites by leveraging two main characteristics: high‐power density motors and modularity. In this way, the robot is able to perform a
