Feasibility study of 4G cellular antennas for eyewear communicating devices
Published 2013“…Three different antennas are examined in terms of obtainable bandwidth potential, reflection coefficient, and specific absorption rate (SAR) values considering two human-head models (SAM and Visible Human). The best antenna is -6 dB matched and has radiation efficiencies around 14% and 36% in respectively low and high frequency bands. …”

Object recognition and localisation from 3D point clouds by maximum likelihood estimation
Published 2017“…Surfaces segmented from depth images are used as the features, unlike ‘interest point’ based algorithms which normally discard such data. Compared to the 6D Hough transform it has negligible memory requirements, and is computationally efficient compared to iterative closest point (ICP) algorithms. …”

Ultra-broadband antenna with robustness to body detuning for 4G eyewear devices
Published 2016“…In order to overcome any negative effects from the antenna's surroundings (frequency detuning due to the head and the hand of the user), the antenna was designed to cover continuously the 700-2700 MHz band with a reflection coefficient below -6 dB instead of a dual-band behavior usually required for 4G operation: 700-960 MHz and 1700-2700 MHz. …”

Wideband tilted beam end-fire antenna using double semi-circular rings
Published 2026“…Across this entire band, the antenna exhibits a return loss better than 12 dB and a gain exceeding 6.5 dBi, with a peak gain of 11.6 dBi at 40 GHz. The overall electrical size of the antenna is 1.28 x 1 x 0.08 $$\lambda _0^3$$ , where $$\lambda _{0}$$ corresponds to the free-space wavelength at 32 GHz. …”

The effect of experimental diabetes and glycaemic control on guided bone regeneration: histology and gene expression analyses
Published 2017“…In 75 animals (25H, 25D, 25CD), one defect was treated with an intracranial and extracranial membrane according to the GBR principle, and one defect was left empty (control); five animals per group were then randomly sacrificed at 3, 7, 15, 30 and 60 days and processed for decalcified histology. In 18 animals (6H, 6D, 6CD), both defects were treated according to the GBR principle; three animals from each group were then randomly sacrificed at 7 and 15 days of healing and employed for gene expression analysis. …”

Effects of sprint interval training on ectopic lipids and tissue-specific insulin sensitivity in men with non-alcoholic fatty liver disease
Published 2018“…IHTG, VAT and ScAT were measured using magnetic resonance spectroscopy or imaging and insulin sensitivity was assessed via dual-step hyperinsulinaemic-euglycaemic clamp with [6,6-D2] glucose tracer. Results: Participants adhered to SIT, completing ≥96.7% of prescribed intervals. …”

COVID-19 lockdowns: a worldwide survey of circadian rhythms and sleep quality in 3911 athletes from 49 countries, with data-driven recommendations
Published 2021“…Athletes went to bed (+ 75 min; 5.4%; d = 1.14) and woke up (+ 150 min; 34.5%; d = 1.71) later during lockdown with an increased total sleep time (+ 48 min; 10.6%; d = 0.83). Lockdown-mediated circadian disruption had more deleterious effects on the sleep quality of individual-sport athletes compared with team-sport athletes (p < 0.001; d = 0.41), elite compared with non-elite athletes (p = 0.028; d = 0.44) and older compared with younger (p = 0.008; d = 0.46) athletes. …”
