Flow and Snow in Complex Terrain: across-scale modelling for a correct surface mass balance

Varun Sharma, Michael Lehning, Wolf Hendrik Huwald, Jérôme François Sylvain Dujardin, Franziska Gerber, Daniela Brito Melo, Nander Wever, Armin Sigmund, David Nicholas Wagner

Preferential deposition of snow precipitation, snow transport and snow sublimation modify the mass which gets incorporated into or removed from the seasonal or perennial snow cover. These processes happen at very small scales from snow grain size to larger ...

QFT without infinities and hierarchy problem

Sander Johannes Nicolaas Mooij

The standard way to do computations in Quantum Field Theory (QFT) often results in the requirement of dramatic cancellations between contributions induced by a "heavy" sector into the physical observables of the "light" (or low energy) sector - the phenome ...

Reconciling resonant leptogenesis and baryogenesis via neutrino oscillations

Inar Timiryasov, Juraj Klaric

Right-handed neutrinos offer an elegant solution to two well-established phenomena beyond the Standard Model (SM)-masses and oscillations of neutrinos, as well as the baryon asymmetry of the Universe. It is also a minimalistic solution, since it requires o ...

Constraining the primordial magnetic field with dwarf galaxy simulations

Pascale Jablonka, Yves Revaz, Mahsa Sanati

Using a set of cosmological hydro-dynamical simulations, we constrained the properties of primordial magnetic fields by studying their impact on the formation and evolution of dwarf galaxies. We performed a large set of simulations (8 dark matter only and ...

Piezoelectric Grippers for Mobile Micromanipulation

Tristan Abondance, Kaushik Jayaram

The ability to efficiently and precisely manipulate objects in inaccessible environments is becoming an essential requirement for many applications of mobile robots, particularly at small sizes. Here, we propose and implement a mobile micromanipulation sol ...

Micropipette calibration by differential pressure measurements

Philippe Renaud, David Vincent Bonzon

The pipetting of small volumes, typically ranging between a few and one thousand microliters (mu l), is widely used in many laboratories and essentially relies on air displacement to aspirate and dispense the liquid contained in a small plastic tip. While ...

Preferential Deposition of Snow and Dust Over Hills: Governing Processes and Relevant Scales

Michael Lehning, Marc Parlange, Francesco Comola, Marco Giovanni Giometto

Preferential deposition of snow and dust over complex terrain is responsible for a wide range of environmental processes and accounts for a significant source of uncertainty in the surface mass balances of cold and arid regions. Despite the growing body of ...

Beryllium melting and erosion on the upper dump plates in JET during three ITER-like wall campaigns

Olivier Sauter, Ambrogio Fasoli, Basil Duval, Stefano Coda, Jonathan Graves, Yves Martin, Duccio Testa, Patrick Blanchard, Alessandro Pau, Cristian Sommariva, Henri Weisen, Richard Pitts, Yann Camenen, Jan Horacek, Javier García Hernández, Marco Wischmeier, Nicola Vianello, Mikhail Maslov, Federico Nespoli, Yao Zhou, David Pfefferlé, Davide Galassi, Antonio José Pereira de Figueiredo, Jonathan Marc Philippe Faustin, Liang Yao, Dalziel Joseph Wilson, Hamish William Patten, Samuel Lanthaler, Bernhard Sieglin, Otto Asunta

Data on erosion and melting of beryllium upper limiter tiles, so-called dump plates (DP), are presented for all three campaigns in the JET tokamak with the ITER-like wall. High-resolution images of the upper wall of JET show clear signs of flash melting on ...

Local surface mass balance processes in East Antarctica

Varun Sharma, Michael Lehning, Wolf Hendrik Huwald, Nander Wever, Francesco Comola, Eric Sauvageat

In Antarctica, direct observations of key processes shaping the surface mass balance such as precipitation and snow deposition, wind transport of snow, and sublimation, are sparse due to the extreme environment and related difficulties in measuring the var ...

Local snow transport and surface evolution processes in East Antarctica

Varun Sharma, Michael Lehning, Wolf Hendrik Huwald, Nander Wever, Francesco Comola, Eric Sauvageat, Philip Crivelli

In Antarctica, direct measurements of processes shaping the surface mass balance such as precipitation, accumulation and erosion, drifting and blowing snow, and sublimation, are sparse and challenging due to the extreme environment and related difficulties ...
