On double-descent in uncertainty quantification in overparametrized models

Lenka Zdeborová, Florent Gérard Krzakala, Bruno Loureiro, Lucas Andry Clarte

Uncertainty quantification is a central challenge in reliable and trustworthy machine learning. Naive measures such as last-layer scores are well-known to yield overconfident estimates in the context of overparametrized neural networks. Several methods, ra ...

Operating Temperatures and Diurnal Temperature Variations of Modules Installed in Open-Rack and Typical BIPV Configurations

Christophe Ballif, Alessandro Francesco Aldo Virtuani, Andrew Wayne Fairbrother

Because of building skin integration with restricted or reduced rear-side ventilation, elevated operating temperatures are expected in building-integrated photovoltaics (BIPV) modules and systems, which may impact their long performance and reliability. Th ...

Ultra low quantum decoherence nano-optomechanical systems

Mohammadjafar Bereyhi

Thermal motion of a room-temperature mechanical resonator typically dominates the quantum backaction of its position measurement. This is a longstanding barrier for exploring cavity optomechanics at room temperature. In order to enter the quantum regime of ...

Thermal conductivity of glassy GeTe4 by first-principles molecular dynamics

Assil Bouzid

A transient thermal regime is achieved in glassy GeTe4 by first-principles molecular dynamics following the recently proposed ''approach-to-equilibrium'' methodology. The temporal and spatial evolution of the temperature do comply with the time-dependent s ...

Thermodynamic properties of highly frustrated quantum spin ladders: Influence of many-particle bound states

Frédéric Mila, Bruce Normand

Quantum antiferromagnets have proven to be some of the cleanest realizations available for theoretical, numerical, and experimental studies of quantum fluctuation effects. At finite temperatures, however, the additional effects of thermal fluctuations in t ...

Centrifuge modelling of heating effects on energy pile performance in saturated sand

Lyesse Laloui

The operation of energy pile in summer can expel excessive heat of the buildings into the ground by the use of a heat pump. Despite of having been implemented for decades, the design of energy pile still relies heavily on empiricism as there is still limit ...

Particle Swarm Optimization and Kalman Filtering for Demand Prediction of Commercial Buildings

François Maréchal, Samira Fazlollahi, Araz Ashouri

The integration of weather forecasts and demand prediction into the energy management system of buildings is usually achieved using a model-based predictive control. The performance of such control techniques strongly depends on the accuracy of the thermal ...

MilliKelvin resolution in cryogenic temperature distributed fibre sensing based on coherent Rayleigh scattering

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Xin Lu

The response of a distributed temperature sensor based on coherent Rayleigh scattering is experimentally studied in the temperature range from 77 K up to 300 K, using fibres with standard and ORMOCER coating. A precise and absolute frequency scan is perfor ...

In situ TEM study of reduction and reoxidation of NiO/ceramic composites

Quentin Thomas Jeangros

Nickel/ceramic solid oxide fuel cell anodes exhibit a dimensional instability when experiencing a reduction-oxidation cycle. As fuel is supplied on the anode side, the as-sintered nickel oxide phase (NiO) reduces to metallic Ni and then remains in this sta ...

Double-diffusive convection in Lake Kivu

Alfred Johny Wüest

Double-diffusive staircases with a total of 230-350 mixed layers and sharp interfaces were observed in nine microstructure temperature profiles measured during February 2004 in Lake Kivu. The presence of these staircases at depths. 120 m indicates that dia ...

Assessment of irradiation embrittlement of the Eurofer97 steel after 590 MeV proton irradiation

Philippe Spätig

The irradiation hardening of the Eurofer97 steel following 590 MeV proton irradiations was determined at three different irradiation temperatures, 50 °C, 250 °C and 350 °C, and various doses up to about 1.3 displacement per atom. The dose and temperature d ...

Differential-thermal analysis around and below the critical temperature T-c of various low-T-c superconductors: A comparative study

Helmuth Berger

We present specific-heat data on the type-II superconductors V3Si, LuNi2B2C and NbSe2 which were acquired with a low-temperature thermal analysis (DTA) technique. We compare our data with available literature data on these superconductors. In the first par ...
