Probing magnetism in 2D materials at the nanoscale with single-spin microscopy

The discovery of ferromagnetism in two-dimensional (2D) van der Waals (vdW) crystals has generated widespread interest. Making further progress in this area requires quantitative knowledge of the magnetic properties of vdW magnets at the nanoscale. We used ...

Investigation of the Intrinsic Permeability of MX-80 Bentonite through a 4-Scale Analysis of Its Fabric

Lyesse Laloui, Etienne André Cassini

MX-80 granular bentonite is expected to be used as a buffer material for high level nuclear waste storage in Switzerland. This material is composed of 85% of smectite clay and exhibits a particular structure with four different scales. MX-80 macroscopic pr ...

Dynamic Valuation of Delinquent Credit-Card Accounts

Thomas Alois Weber

This paper introduces a dynamic model of the stochastic repayment behavior exhibited by delinquent credit-card accounts. Based on this model, we construct a dynamic collectability score (DCS) which estimates the account-speciﬁc probability of collecting a ...

A General Formula for Valuing Defaultable Securities

Pierre Collin Dufresne

Previous research has shown that under a suitable no-jump condition, the price of a defaultable security is equal to its risk-neutral expected discounted cash flows if a modified discount rate is introduced to account for the possibility of default. Below, ...

In vivo measurement of glucose utilization in rats using a beta-microprobe: direct comparison with autoradiography

Pierre Magistretti, Jean-Marie Petit, Christian Morel

A new beta-microprobe (betaP) has been used to locally measure the time-concentration curve of a radiolabeled substance. The betaP, analogous to positron emission tomography methodology, is useful for in vivo animal studies because it can acquire time-conc ...

Do Credit Spreads Reflect Stationary Leverage Ratios?

Pierre Collin Dufresne

Most structural models of default preclude the firm from altering its capital structure. In practice, firms adjust outstanding debt levels in response to changes in firm value, thus generating mean-reverting leverage ratios. We propose a structural model o ...

EPR on aqueous Gd3+ complexes and a new analysis method considering both line widths and shifts

André Merbach, Lothar Helm, Alain Borel, Eva Jakab Toth

We performed variable temperature (0–100°C), concentration and frequency (9.425, 75, 150 and 225 GHz) continuous wave electron paramagnetic resonance (EPR) measurements on three different Gd(III) compounds: [Gd(H2O)8]3+, [Gd(DOTA)(H2O)]− (DOTA: 1,4,7,10-te ...

Neoclassical tearing modes

Olivier Sauter, Holger Reimerdes, Hartmut Zohm

Neoclassical tearing modes are one of the most serious concerns for operation on a next-step tokamak device. The modes occur on present tokamaks at normalized pressure (beta (N)) values comparable to those envisaged For baseline scenarios in future devices ...

Cold-field-emission test of the fatigued state of Pb(ZrxTi1-x)O-3 films

Nava Setter, Alexander Tagantsev, Igor Stolichnov, Enrico Colla

Fatigue phenomena occurring in Pb(ZrxTi1-x)O-3 ferroelectric thin-film capacitors (FECAP) with Pt electrodes are studied by means of conduction measurements in the cold-field-emission (tunneling) regime. We have determined that conduction in virgin FECAPs ...
