Innovative SETI by the KLT [PDF]

open access: yesProceedings of Bursts, Pulses and Flickering: wide-field monitoring of the dynamic radio sky — PoS(Dynamic2007), 2008
SETI searches are, by definition, the extraction of very weak radio signals out of the cosmic background noise. When SETI was born in 1959, it was "natural" to attempt this extraction by virtue of the only detection algorithm well known at the time: the Fourier Transform (FT).

Higher derivative quartic vertex of f(R) gravity in light-cone gauge

open access: yesNuclear Physics B, 2018
In the recent studies of four-dimensional Einstein–Hilbert action, quite a few interesting results such as the Kawai–Lewellen–Tye (KLT) relations, MHV-Lagrangian and quadratic forms have been reported. These results naturally raise an important question:

On polytopes and generalizations of the KLT relations

open access: yesJournal of High Energy Physics, 2020
We combine the technology of the theory of polytopes and twisted intersection theory to derive a large class of double copy relations that generalize the classical relations due to Kawai, Lewellen and Tye (KLT).

Joint Content and Shape Adaptive Transforms Based on a GMRF Model for Coding Arbitrarily Shaped Image Segments

open access: yesIEEE Access
It is known that shape-adaptive (SA) transform coding can outperform block-based transform coding for images. However, there is no simple way to construct optimal transforms for arbitrarily shaped image segments.

Soma-Axon Coupling Configurations That Enhance Neuronal Coincidence Detection [PDF]

open access: yes, 2019
Coincidence detector neurons transmit timing information by responding preferentially to concurrent synaptic inputs. Principal cells of the medial superior olive (MSO) in the mammalian auditory brainstem are superb coincidence detectors.

A Hybrid Motion Estimation for Video Stabilization Based on an IMU Sensor

open access: yesSensors, 2018
Recorded video data must be clear for accuracy and faster analysis during post-processing, which often requires video stabilization systems to remove undesired motion.
