Fluctuations of stochastic PDEs with long-range correlations

We study the large-scale dynamics of the solution to a nonlinear stochastic heat equation (SHE) in dimensions d≥3 with long-range dependence. This equation is driven by multiplicative Gaussian noise, which is white in time and coloured in space with non-in ...

Geometric transformation of finite element methods: Theory and applications

Martin Werner Licht

We present a new analysis of finite element methods for partial differential equations over curved domains. In many applications, a change of variables translates a physical Poisson problem over a curved physical domain into a parametric Poisson problem ov ...

Flexible Sensor and Readout Circuitry for Continuous Ion Sensing in Sweat

Sandro Carrara, Ata Jedari Golparvar, Ali Meimandi

In this letter, we present a custom-designed and flexible readout circuitry for the characterization of flexible and planar electrolyte-gated carbon nanotube field-effect transistor-based biosensors for ammonium detection in sweat. We employed spray-deposi ...

Plasma etching for fabrication of complex nanophotonic lasers from bonded InP semiconductor layers

Kirsten Emilie Moselund

Integrating optically active III-V materials on silicon/insulator platforms is one potential path towards improving the energy efficiency and performance of modern computing. Here we demonstrate the applicability of direct wafer bonding combined with plasm ...

Performance review of the joints for the ITER poloidal field coils

Kamil Sedlák, Hugues Marie Alain Bajas

For large scale magnets wound with cable-in-conduit conductors, the safe operation of the joints is of paramount importance to guarantee adequate reliability and stability margin of the whole magnet. For this reason, during the R & D activities undertaken ...

Mass-zero constrained dynamics for simulations based on orbital-free density functional theory

Sara Bonella

A new algorithm for efficient and fully time-reversible integration of first-principles molecular dynamics based on orbital-free density functional theory (OFDFT) is presented. The algorithm adapts to this nontrivial case, the recently introduced Mass-Zero ...

First Search for Exclusive Diphoton Production at High Mass with Tagged Protons in Proton-Proton Collisions at root s=13 TeV

Jan Steggemann

A search for exclusive two-photon production via photon exchange in proton-proton collisions, pp -> p gamma gamma p with intact protons, is presented. The data correspond to an integrated luminosity of 9.4 fb(-1) collected in 2016 using the CMS and TOTEM d ...

Evidence on the effects of main-chamber neutrals on density shoulder broadening

Basil Duval, Nicola Vianello, Holger Reimerdes, Christian Gabriel Theiler, Umar Sheikh, Cedric Kar-Wai Tsui, Mirko Wensing, Marcelo Baquero Ruiz, Artur Perek, Sophie Danielle Angelica Gorno

Evidence that density shoulder broadening is dependent on high main-chamber neutral density is presented. Shoulder broadening does notoccur when the sources for main-chamber neutrals are minimized using divertor baffles and wide gaps to the first wall (sim ...

Leidenfrost flows: instabilities and symmetry breakings

François Gallaire

Leidenfrost drops were recently found to host strong dynamics. In the present study, we investigate both experimentally and theoretically the flow structures and stability inside a Leidenfrost water drop as it evaporates, starting with a large puddle. As r ...

Many-Body Study of Iron(III)-Bound Human Serum Transferrin br

Edward Baxter Linscott

We present the very first density functional theory and dynamical meanfield theory calculations of iron-bound human serum transferrin. Peaks in the optical conductivity at250, 300, and 450 nm were observed, in line with experimental measurements. Spin mult ...

Three-Dimensional Confinement of Water: H2O Exhibits Long-Range (> 50 nm) Structure while D2O Does Not

Sylvie Roke, Nathan Dupertuis, Cornelis Ulrich Lütgebaucks, Orly Bagunu Tarun

Water is the liquid of life thanks to its three-dimensional adaptive hydrogen (H)-bond network. Confinement of this network may lead to dramatic structural changes influencing chemical and physical transformations. Although confinement effects occur on a < ...

Gravity-driven coatings on curved substrates: a differential geometry approach

François Gallaire, Pier Giuseppe Ledda

Drainage and spreading processes in thin liquid films have received considerable attention in the past decades. Yet, our understanding of three-dimensional cases remains sparse, with only a few studies focusing on flat and axisymmetric substrates. Here, we ...

Performance Limitations and Analysis of Silicon Heterojunction Solar Cells Using Ultra-Thin MoOx Hole-Selective Contacts

Christophe Ballif, Mathieu Gérard Boccard, Luca Massimiliano Antognini, Jean Cattin, Julie Amandine Dreon, Gabriel Christmann, Vincent Philippe Paratte

We recently showed that silicon heterojunction solar cell with MoOx-based hole-selective contact could reach 23.5% in efficiency with MoOx layers of 4 nm. Such thin MoOx layer enables a considerable current-density gain of over 1 mA/cm(2) compared to the u ...

Low-Power Electro-Optic Actuators for Large-Scale Programmable Photonic Circuits

Niels Quack, Alain Yuji Takabayashi, Hamed Sattari

Photonic integrated circuits are becoming increasingly more complex, especially with the emergence of programmable photonic circuits. These require many tunable photonic elements, such as electro-optic phase shifters and tunable couplers. We will discuss o ...

Microsecond melting and revitrification of cryo samples

Marcel Drabbels, Ulrich Lorenz, Pavel Olshin, Jonathan Mark Voss, Oliver Florian Harder

The dynamics of proteins that are associated with their function typically occur on the microsecond timescale, orders of magnitude faster than the time resolution of cryo-electron microscopy. We have recently introduced a novel approach to time-resolved cr ...
