Measuring electro-adhesion pressure before and after contact

Electro-adhesion (EA) is a low-power, tunable, fast and reversible electrically-controlled adhesion method, effective on both conducting and insulating objects. Typically, only the electro-adhesive detachment force, i.e., the force required to separate an ...

Dopamine Transporter, PhosphoSerine129 alpha-Synuclein and alpha-Synuclein Levels in Aged LRRK2 G2019S Knock-In and Knock-Out Mice

Salvatore Novello, Chiara Domenicale

The G2019S mutation in leucine rich-repeat kinase 2 (LRRK2) is a major cause of familial Parkinson's disease. We previously reported that G2019S knock-in mice manifest dopamine transporter dysfunction and phosphoSerine129 alpha-synuclein (pSer129 alpha-syn ...

Active microrheology in corrugated channels: Comparison of thermal and colloidal baths

Ignacio Pagonabarraga Mora

Hypothesis: The dynamics of colloidal suspension confined within porous materials strongly differs from that in the bulk. In particular, within porous materials, the presence of boundaries with complex shapes entangles the longitudinal and transverse degre ...

Non-linear Shubnikov-de Haas oscillations in the self-heating regime

Philip Johannes Walter Moll, Matthias Carsten Putzke, Chunyu Guo, Xiangwei Huang, Jonas De Jesus Diaz Gomez

We demonstrate a non-linear measurement scheme of the Shubnikov-de Haas effect based on Joule self-heating that builds on ideas of the 3 ?-method used in thin films. While the temperature dependence of the resistance, R(T), of clean metals at low temperatu ...

Mechanical and hydraulic transport properties of transverse-isotropic Gneiss deformed under deep reservoir stress and pressure conditions

Marie Estelle Solange Violay, Mateo Alejandro Acosta

In central Europe, many geo-energy reservoirs have revealed to be hosted in transverse isotropic crystalline rock, where the rock's mechanical and hydraulic transport properties are poorly constrained. Here, we performed triaxial experiments on Cresciano G ...

Dynamics of optical forces and torques in plasmonic systems: a surface integral equation

Olivier Martin, Karim Achouri, Andrei Kiselev

A novel approach is introduced to determine the time evolution of optical forces and torques on arbitrary shape nanostructures by combining Maxwell's stress tensor with the surface integral equation method (SIE). Conventional time averaging of Maxwell’s st ...

Electrical transport in onion-like carbon-PMMA nanocomposites

László Forró, Arnaud Magrez, Claudio Grimaldi, Maryam Majidian

We report electrical conductivity measurements of polymethyl-methacrylate filled by onion-like carbon particles with a primary particle size of approximate to 5 nm. We show that the conductivity sigma is exceptionally high even at very low loadings and tha ...

On the benefits of a stress criterion for the simulation of cup drawing process

Roland Logé

Experimental and numerical cup drawing process has been investigated on 0.65 mm zinc sheets. The cup exhibits anisotropic earrings due to the material microstructure. The material formability is studied through elliptical bulge tests in the rolling, diagon ...

Temperature Dependence of the Vacancy Formation Energy in Solid He-4

Riccardo Rota

We studied the thermal effects on the behavior of incommensurate solid He-4 at low temperatures using the path integral Monte Carlo method. Below a certain temperature, depending on the density and the structure of the crystal, the vacancies delocalize and ...

Semiparametric Bayesian Risk Estimation for Complex Extremes

Thomas Lugrin

Extreme events are responsible for huge material damage and are costly in terms of their human and economic impacts. They strike all facets of modern society, such as physical infrastructure and insurance companies through environmental hazards, banking an ...

Benchmarking of Homojunction Strained-Si NW Tunnel FETs for Basic Analog Functions

Mihai Adrian Ionescu, Cem Alper, Arnab Biswas, Florin Udrea

This paper reports a compact ambipolar model for homojunction strained-silicon (sSi) nanowire (NW) tunnel FETs (TFETs) capable of accurately describing both I-V and G-V characteristics in all regimes of operation, n- and p-ambipolarity, the superlinear ons ...

Pressure-dependent elastic and transport properties of porous and permeable rocks: Microstructural control

Lucas Xan Pimienta, Christian David

Although several studies aimed at linking electrical and hydraulic transport properties in rocks, the existing models remain at most incomplete. Based on this observation, in addition to the transport properties, this contribution investigates the pressure ...

Time-Dependent Diffusion MRI in Cancer: Tissue Modeling and Applications

Olivier Benoit Thomas Reynaud

In diffusion weighted imaging (DWI), the apparent diffusion coefficient (ADC) has been recognized as a useful and sensitive surrogate for cell density, paving the way for non-invasive tumor staging, and characterization of treatment efficacy in cancer. How ...

Time-dependent correlations in quantum magnets at finite temperature

Thomas Keller, Felix Groitl

In this Rapid Communication we investigate the time dependence of the gap mode of copper nitrate at various temperatures. We combine state-of-the-art theoretical calculations with high precision neutron resonance spin-echo measurements to understand the an ...

Bayesian uncertainty management in temporal dependence of extremes

Anthony Christopher Davison, Thomas Lugrin, Jonathan A. Tawn

Both marginal and dependence features must be described when modelling the extremes of a stationary time series. There are standard approaches to marginal modelling, but long-and short-range dependence of extremes may both appear. In applications, an assum ...

Unaltered cocaine self-administration in the prenatal LPS rat model of schizophrenia

Erika Myrna Borcel Novoa

Although cocaine abuse is up to three times more frequent among schizophrenic patients, it remains unclear why this should be the case and whether sex influences this relationship. Using a maternal immune activation model of schizophrenia, we tested whethe ...

Pressure dependence of the magnetization plateaus ofSrCu2(BO3)2

Frédéric Mila

We show that the critical fields of the magnetization plateaus of the Shastry-Sutherland model decrease significantly upon increasing the ratio of inter- to intradimer coupling and accordingly that the magnetization plateaus of SrCu2(BO3)2 shift to lower f ...
