Optomechanical Mapping of Ferroelectric Domains and the Piezo-Photovoltaic Effect in Ba- and Ni-Doped (K0.5Na0.5)NbO3
The piezo-photovoltaic effect has been recently proposed as an analogy of the flexo-photovoltaic effect in noncentrosymmetric ferroelectrics that are also piezoelectric in […]
Ultra Wideband Radar based Indoor Activity Monitoring for Elderly Care
In this paper, we propose an unobtrusive method and architecture for monitoring a person’s presence and collecting his/her health-related parameters simultaneously in […]
The Plausibility Paradox for Resized Users in Virtual Environments
This paper identifies and confirms a perceptual phenomenon: when users interact with simulated objects in a virtual environment where the users’ scale […]
Uncertainty quantification in skin cancer classification using three-way decision-based Bayesian deep learning
Accurate automated medical image recognition, including classification and segmentation, is one of the most challenging tasks in medical image analysis. Recently, deep […]
Link Activation Using Variational Graph Autoencoders
An unsupervised method is proposed for link activation in wireless networks by identifying clusters of interfering users. A k-nearest neighbors interference graph […]
Drug diffusivities in nanofibrillar cellulose hydrogel by combined time-resolved Raman and fluorescence spectroscopy
Hydrogels, natural and synthetic origin, are actively studied for their use for implants and payload carriers. These biomaterials for delivery systems have […]
Dielectric lens antennas for 300-GHz applications
Implementation of proper wireless links at submillimetre-wave and terahertz (THz) frequencies requires high-gain antennas. This simulation-based study investigates the performance of dielectric […]
Dual-Polarized Filtering Antenna for mm-Wave 5G Base Station Antenna Array
This paper presents a dual-polarized filtering antenna designed for a 5G mm-Wave base station phased array. The out-of-band radiation of a stacked […]
A 5.4-GHz 2/3/4-modulus fractional frequency divider circuit in 28-nm CMOS
This paper describes the design and post-layout simulations of a 2/3/4- modulus frequency divider circuit, accompanied with an accumulator that controls the […]
Digital biomarkers of symptom burden self-reported by perioperative patients undergoing pancreatic surgery
Background: Cancer treatments can cause a variety of symptoms that impair quality of life and functioning but are frequently missed by clinicians. […]
