Optical method supported by machine learning for dynamics of C‐reactive protein concentrations changes detection in biological matrix samples

Journal of Biophotonics, EarlyView.
The proposed method is based on an optical system supported by machine learning, that allows to monitoring dynamic of C‐reactive protein (CRP) level changes in near‐real time. Monitoring the presence level of CRP in wastewater might be used to track the spread of diseases or identify areas with increased morbidity.

Voltage over‐scaling CNT‐based 8‐bit multiplier by high‐efficient GDI‐based counters

IET Computers &Digital Techniques, Volume 17, Issue 1, Page 1-19, January 2023., 2023
A new low‐power and high‐speed multiplier is presented based on voltage over scaling (VOS) technique and new 5:3 and 7:3 counter cells. VOS technique is used to reduce power consumption in digital circuits, but different voltage levels of the VOS increase the delay in different stages of a multiplier.

Fast‐switchable polarization‐dependent bifocal lenses for AR displays

Journal of the Society for Information Display, EarlyView.
Polarization‐dependent bifocal Pancharatnam‐Berry phase lenses, fabricated via photoalignment, integrate bifocal functionality for AR displays. An electrically suppressed helix ferroelectric liquid crystal polarization rotator enables rapid switching (35 μs) between dual depths or field‐of‐views (FOVs) in longitudinal and transverse configurations ...

Improved malicious node detection method for detecting a bait in an extensive network for getting the maximum throughput

IET Communications, EarlyView., 2022
Abstract Mobile Ad‐hoc Network (MANET) is an ad hoc Wireless subset with a unique dynamic geometry of the system and movable nodes. The MANETs are auto‐organized networks that permit mobility without infrastructure. Specific protocols for MANET routing are provided with these attributes.

Full‐color holographic image capture: Cholesteric liquid crystal circular polarizer combined with geometric phase lens reduces noise in self‐interference incoherent digital holography

Journal of the Society for Information Display, EarlyView.
By using cholesteric liquid crystals as circular polarization filters in quarter‐waveplate condition GPL (QW‐GPL) based SIDH, a stable circular polarization state is ensured, which reduces color distortion and polarization noise, thereby significantly enhancing the reconstructed image quality in full‐color QW‐GPL‐based SIDH.

Sphere‐decoding based equalization for reduced‐zero‐padding orthogonal time frequency space modulation

IET Communications, Volume 17, Issue 1, Page 63-72, January 2023., 2023
Abstract This work studies the equalization methods for the reduced zero‐padding version of the orthogonal time frequency space modulation. Here, the focus is on applications in low data rate scenarios such as the Internet of Things, and the case where the number of subcarriers and time slots are small will be considered.
