Coronary angiography video interpolation methods to reduce x-ray exposure frequency

Researchers develop a new method for reducing X-ray exposure during coronary angiography procedures by applying video interpolation techniques to frame rates. The approach uses a dataset of 95,039 images and achieves significant reductions in X-ray exposure frequency.

Skoltech studies collective behavior of nanosatellites

Researchers at Skoltech's Space Center have developed an algorithm to measure the geomagnetic field using CubeSats in a tetrahedral orbital formation. The system uses Kriging interpolation to predict magnetic field values, enabling improved attitude control and station-keeping systems.

DJI Air 3 (RC-N2)

DJI Air 3 (RC-N2) captures 4K mapping passes and environmental surveys with dual cameras, long flight time, and omnidirectional obstacle sensing.

Comparison of global climatologies confirms warming of the global ocean

A new ocean climatology reveals the global ocean is warming due to changes in atmospheric conditions, with temperatures increasing by 0.05°C over the past 25 years. The study provides valuable background information for various applications and highlights the importance of periodic updates to ocean climatologies.

New techniques for cerebral white matter fiber tracing

Researchers have developed a tri-linear interpolation algorithm for accurate white matter fiber tracking, resulting in longer tracked fibers with smoother orientations. This method achieved reliable tracking results that aligned with actual brain anatomy and disease conditions.
