Dataset Construction via Attention for Aspect Term Extraction with Distant Supervision

Athanasios Giannakopoulos, Claudiu-Cristian Musat, Diego Matteo Antognini

Aspect Term Extraction (ATE) detects opinionated aspect terms in sentences or text spans, with the end goal of performing aspect-based sentiment analysis. The small amount of available datasets for supervised ATE and the fact that they cover only a few dom ...

A Hybrid CDAC-Threshold Configuring SAR ADC in 28nm FDSOI CMOS

Mustafa Kilic, Yusuf Leblebici, Themistoklis Mavrogordatos

In this paper, a 9-bit 1.3 GS/s single channel SAR ADC is presented. In conventional SAR ADCs, the capacitive DAC size grows exponentially with respect to converter resolution. This results in both signal bandwidth and conversion speed reduction. The propo ...

Sub-terahertz spectroscopy of magnetic resonance in BiFeO3 using a vector network analyzer

Jean-Philippe Ansermet, Arnaud Magrez, Emile Jacques de Rijk, Christian Caspers, Varun Paresh Gandhi

Detection of sub-THz spin cycloid resonances (SCRs) of stoichiometric BiFeO3 (BFO) was demonstrated using a vector network analyzer. Continuous wave absorption spectroscopy is possible, thanks to heterodyning and electronic sweep control using frequency ex ...

Combined Optical and Electrical Spectrum Shaping for High-Baud-Rate Nyquist-WDM Transceivers

Camille Sophie Brès

We discuss the benefits and limitations of optical time-division multiplexing (OTDM) techniques based on the optical generation of a periodic train of sinc pulses for wavelength-division multiplexing (WDM) transmission at high baud rates. It is shown how t ...

Dynamic Range Limiting of HRTFs: Principle and Objective evaluation

Hervé Lissek, Patrick Marmaroli, Gilles André Courtois, Lukas Rohr

This research addresses the challenge of incorporating dynamic range limiting of the magnitude response of HRTFs for hearing-impaired listeners who are using binaural hearing aids. In this application, a direct implementation of spatialization using the or ...

A Digital Spectrum Shaping Signaling Serial-Data Transceiver with Crosstalk and ISI Reduction Property in Multi-Drop Interfaces

Seyed Armin Tajalli, Yusuf Leblebici, Gain Kim, Kiarash Gharibdoust

A transceiver (TRX) architecture employing spectrum shaping signaling scheme is proposed, which can significantly reduce inter-symbol interference (ISI) and crosstalk in multi-drop interfaces. The proposed TRX architecture relies on digital implementation ...

Dynamic nuclear polarization by frequency modulation of a tunable gyrotron of 260 GHz

Stefano Alberti, Jean-Philippe Ansermet, Falk Hans Braunmüller, Philippe Cuanillon, Murari Soundararajan, Dongyoung Yoon

An increase in Dynamic Nuclear Polarization (DNP) signal intensity is obtained with a tunable gyrotronproducing frequency modulation around 260 GHz at power levels less than 1W. The sweep rate of frequency modulation can reach 14 kHz, and its amplitude is ...

Gain vs phase in BOTDA setups

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Alejandro Dominguez Lopez

We evaluate the Brillouin frequency shift (BFS) determination error when using the Brillouin phase spectrum (BPS) instead of the Brillouin gain spectrum (BGS) in BOTDA setups. We compare the error obtained in the BFS determination in both cases, both with ...
