A Convoy of Magnetic Millirobots Transports Endoscopic Instruments for Minimally‐Invasive Surgery
Advanced Science, EarlyView.The first electrocautery procedure performed by a team of millirobots (TrainBots) is presented. Enhanced with optimized feet, millirobots form a convoy to facilitate the collaborative transportation of wires and catheters through biological lumens, e.g. bile ducts. It opens up the possibility of using a team of mini‐robots in future endoscopic surgery.

Modeling the spatial evolution wildfires using random spread process
Environmetrics, Volume 33, Issue 8, December 2022., 2022 Abstract The study of wildfire spread and the growth of the area burned is an important task in ecological studies and in other contexts. In this work we present a model for fire spread and show the results obtained from simulations of burned areas. The model is based on probabilities of fire at different locations. Such probabilities are obtained from

A Survey on Elliptic Curve Cryptography
INTERNATIONAL JOURNAL OF RESEARCH IN ADVANCE ENGINEERING, 2015 Elliptic curve cryptography (ECC) is the most efficient public key encryption scheme based onelliptic curve concepts that can be used to create faster, smaller, and efficient cryptographic keys. ECCgenerates keys through the properties of the elliptic curve equation instead of the conventional method ofkey generation.

High‐Speed Hyperspectral Imaging for Near Infrared Fluorescence and Environmental Monitoring
Advanced Science, EarlyView.This study introduces a fast hyperspectral imaging method in the near‐infrared range (HyperNIR). Combining tunable polarization optics with a phasor‐based approach, HyperNIR captures detailed spectral information with just three images. The applicability is showcased by distinguishing NIR fluorophores that are separated by 5 nm.
