—Simultaneous wireless information and power transfer (SWIPT) has emerged as a viable technique to energize and connect low-power autonomous devices and enable future Internet of Things (IoT). A major challenge of SWIPT is the energy consumption of the receiver of such low-power devices. An attractive low-power…

—We build a realistic Simultaneous Wireless Information and Power Transfer (SWIPT) prototype and experimentally analyse the harvested energy and throughput trade-off. Both time-switching and power splitting receiver architectures are implemented, and the performance comparison is carried out. Systematic SWIPT…

In this paper, orbital angular momentum (OAM) is integrated with power splitting based simultaneous wireless information and power transfer (SWIPT-PS) and cooperative non-orthogonal multiple access (CNOMA-SWIPT-PS) downlink transmission, called as CNOMA-SWIPT-PS-OAM. The proposed CNOMA-SWIPT-PS-OAM scheme enhances the…

SWIFT (SWeep Imaging with Fourier Transform) (1) utilizes gapped frequencyswept pulses (2) for excitation; signal is received after a short dead interval. SWIFT can be categorized as one of the general class of short-T2 or T2 * sensitive sequences (3) which possess a very short time interval between signal excitation…

Square-wave voltammetry (SWV) is widely used for electrochemical biosensing because it enables sensitive, temporally resolved measurement of redox reporter signals. However, automated quantification of SWV signal remains challenging for long duration and in vivo measurements, where voltammograms can exhibit changing…

SwrA activates flagellar gene expression in Bacillus subtilis to increase the frequency of motile cells in liquid and elevate flagellar density to enable swarming over solid surfaces. Here we use ChIP-seq to show that SwrA interacts with many sites on the chromosome in a manner that depends on the response regulator…

Technical evaluation of swimming performance is an essential factor of elite athletic preparation. Novel methods of analysis, incorporating body worn inertial sensors (i.e., Microelectromechanical systems, or MEMS, accelerometers and gyroscopes), have received much attention recently from both research and commercial…

'David C. Clarke' 'Mathias Kristiansen'] Background Swimmers commonly access performance metrics such as lap splits, distance, and pacing information between work bouts while they rest. Recently, a new category of tracking devices for swimming was introduced with the FORM Smart Swim Goggles (FORM Goggles). The goggles…

A description is provided of how the Square Wave Method (SWM) can be applied to analyze sequences of bases of human DNA. The results obtained are displayed using the Square Wave Transform (SWT), an SWM tool. It is hypothesized that the results of this analysis can be of interest, in certain cases, to understand the…

Colloidal indium antimonide (InSb) quantum dots (QDs) are highly promising nanomaterials for SWIR photodetectors due to their optical properties, solution processability, and low toxicity. Here, we present surface engineering of colloidal InSb QDs and an investigation of the intrinsic and extrinsic photoresponse time…

Nowadays, wearables are a must-have tool for athletes and coaches. Wearables can provide real-time feedback to athletes on their athletic performance and other training details as training load, for example. The aim of this study was to systematically review studies that assessed the accuracy of wearables providing…

Near infrared (NIR) signals are beneficial for biomedical applications due to reduced light absorption, scattering, and autofluorescence in this range, which promises higher signal-to-noise ratios (SNR). Single-walled carbon nanotubes (SWCNTs) fluoresce in the NIR (800 nm – 1700 nm) and serve as building blocks for…

Inertial measurement units (IMU) are proven as efficient tools for swimming analysis by overcoming the limits of video-based systems application in aquatic environments. However, coaches still believe in the lack of a reliable and easy-to-use analysis system for swimming. To provide a broad view of swimmers'…

This study aimed to estimate the trunk twist angle from the shoulder and hip rotation angles in short-distance crawl swimming and to elucidate the twist motion of the relationship between the trunk and the rotation angular velocity in response to changes in swimming speed. Swimming speed during the experimental trials…

Sharp wave ripples (SWRs) are synchronous neurophysiological events in the hippocampus (HPC) linked to memory encoding, consolidation, and recall. In freely moving rodents, SWRs typically occur during brief pauses in locomotion when animals halt to explore their surroundings. Whether this is also the case in primates…
