Resolving Galactic-scale Obscuration of X-Ray AGNs at z & GSIM; 1 with COSMOS-Web
A large fraction of the accreting supermassive black hole population is shrouded by copious amounts of gas and dust, particularly in the distant (z & GSIM; 1) universe. While much of the obscuration is attributed to a parsec-scale torus, there is a known c ...
IOP Publishing Ltd2023Traversing Time Dependent Light Fields for Daylight Glare Evaluation
To understand how daylight gives shape and life to architectural spaces, whether existing or imagined, requires quantifying its dynamism and energy. Maintaining these details presents a challenge to simulation and analysis methods that flatten data into di ...
EPFL2023Annotation-efficient image anomaly detection
The present invention proposes a method for detecting anomalous or out-of-distribution images in a machine learning system (1) comprising a pre-training network with a first encoder, and an anomaly detection network with a second encoder. The system is fir ...
2022Medipix4, a high granularity four sides buttable pixel readout chip for high resolution spectroscopic X-ray imaging at rates compatible with medical CT scans
Medipix4 is the latest member in the Medipix/Timepix family of pixel detector chips aimed at high rate spectroscopic X-ray imaging using high-Z materials. The chip address the limitations of conventional hybrid pixel detectors for X-ray imaging. Its predec ...
EPFL2022Host genomics of SARS-CoV-2 infection
Jacques Fellay, Christian Axel Wandall Thorball
SARS-CoV-2 infected a large fraction of humans in the past 2 years. The clinical presentation of acute infection varies greatly between individuals, ranging from asymptomatic or mild to life-threatening COVID-19 pneumonia with multi-organ complications. De ...
SPRINGERNATURE2022Modeling the small-scale deposition of snow onto structured Arctic sea ice during a MOSAiC storm using snowBedFoam 1.0.
Michael Lehning, Mahdi Jafari, Océane Hames, Marc Schneebeli Zeugin, David Nicholas Wagner
The remoteness and extreme conditions of the Arctic make it a very difficult environment to investigate. In these polar regions covered by sea ice, the wind is relatively strong due to the absence of obstructions and redistributes a large part of the depos ...
COPERNICUS GESELLSCHAFT MBH2022How Does Pre-Trained Wav2Vec 2.0 Perform On Domain-Shifted Asr? An Extensive Benchmark On Air Traffic Control Communications
Petr Motlicek, Juan Pablo Zuluaga Gomez, Amrutha Prasad
Recent work on self-supervised pre-training focus on leveraging large-scale unlabeled speech data to build robust end-to-end (E2E) acoustic models (AM) that can be later fine-tuned on downstream tasks e.g., automatic speech recognition (ASR). Yet, few work ...
IEEE2022Seasonal variation of airborne coarse and fluorescent particles
Julia Schmale, Ivo Fabio Beck, Nora Bergner, Hélène Paule Angot, Lubna Dada, Margarida Teles Nogueira Rolo
Coarse mode aerosols receive relatively little attention in Arctic atmospheric research compared to smaller aerosol populations. However, coarse mode particles have important implications for aerosol-radiation interactions as well as aerosol-cloud interact ...
2022Leaking Secrets Through Compressed Caches
We offer the first security analysis of cache compression, a promising architectural technique that is likely to appear in future mainstream processors. We find that cache compression has novel security implications because the compressibility of a cache l ...
IEEE COMPUTER SOC2021A Simple Mechanistic Model for Friction of Rough Partially Lubricated Surfaces
Jean-François Molinari, Tobias Brink, Gianluca Costagliola, Julie Richard
We report experimental measurements of friction between an aluminum alloy sliding over steel with various lubricant densities. Using the topography scans of the surfaces as input, we calculate the real contact area using the boundary element method and the ...
