Intraoperative perfusion assessment by continuous, low-latency hyperspectral light-field imaging: development, methodology, and clinical application
This study presents a hyperspectral light field system for intraoperative tissue oxygen saturation (????????2) analysis and visualization. We present a correlation method for determining SO2 saturation with low computational demands. We...
Evaluation of a WR6.5 Rotary Joint with two 3D-printed TE01 Mode Transducers
This paper explores a WR6.5 rotary joint based on two 3D-printed mode transducers. Tests from 140 to 170 GHz show about 2 dB of insertion loss across a 16 GHz usable band (145-161 GHz) and less than 15 degree of phase variation, validating 3D...
Dual-Beam Planar D-Band Antenna Array: Filtering Patch Antennas and Dielectric Lens
A hybrid analog beamforming at D-band is demonstrated by integration between an antenna array and a dielectric lens. The beam is collimated on one plane by the antenna array, and on the other by the elliptical lens profile. The antenna element is...

Experimental Characterization of Photodiode Transmitters for Probabilistically Shaped High-Speed THz Wireless Transmission
In this paper, we present an experimental investigation of two distinct THz transmitter architectures. While Terahertz (THz) wireless communication is key for 6G networks, a systematic performance comparison between different photonic-generated...
3D-Aware Latent-Space Reenactment: Combining Expression Transfer and Semantic Editing
3D-LaSR introduces a new way to reenact 3D human heads by navigating the latent space of state-of-the-art Gaussian-splatting GANs, enabling smooth, realistic animations and cross-identity expression transfer from just a single monocular video. By...
Hardware realization of neuromorphic computing with a 4–port photonic reservoir for modulation format identification
We make a deep dive into the fabrication and testing of a photonic reservoir with digital readout. The developed neural network was tested for the identification of modulation formats at 32 Gbaud transmission rates, where it achieved a near-100%...
RIPE: Reinforcement Learning on Unlabeled Image Pairs for Robust Keypoint Extraction
We introduce RIPE, an innovative reinforcement learning-based framework for weakly-supervised training of a keypoint extractor that excels in both detection and description tasks. In contrast to conventional training regimes that depend heavily...
