Anisotropic volumetric behaviour of Opalinus Clay shale upon suction variation

Lyesse Laloui, Alessio Ferrari, Eleonora Crisci, Alberto Minardi

Opalinus Clay shale is under consideration to serve as the host geomaterial for the underground storage of nuclear waste in Switzerland. Water retention behaviour and anisotropic behaviour represent two main features of this geomaterial; however, a compreh ...

Small subset sums

Gergely Ambrus

Let parallel to.parallel to be a norm in R-d whose unit ball is B. Assume that V subset of B is a finite set of cardinality n, with Sigma(v is an element of V) v = 0. We show that for every integer k with 0

Independence number of generalized Petersen graphs

Javad Ebrahimi Boroojeni

Determining the size of a maximum independent set of a graph G, denoted by alpha(G), is an NP-hard problem. Therefore many attempts are made to find upper and lower bounds, or exact values of alpha(G) for special classes of graphs. This paper is aimed towa ...

Different geometries for spin-transfer oscillators

Several geometries have recently been proposed for spin-transfer oscillators, with the purpose of optimizing the output power and the frequency dependence on the applied current, as well as minimizing the external magnetic field required to stabilize magne ...

Natural cement and monumental restoration

Christophe Gosselin

Natural cement, called "Roman" cement, was invented at the end of the 19th century and played an important role in the development of civil engineering works until the 1860s. More surprisingly, it was also used to restore historic buildings, such as gothic ...

Modeling of direct load transmission in sandwich beams with lightweight concrete

Thomas Keller, Till Vallée, Erika Schaumann

The direct load transmission behavior of hybrid sandwich beams consisting of a bottom fiber-reinforced polymer skin and a top concrete skin was investigated experimentally. The sandwich core consisted of lightweight concretes of different brittleness (sand ...

Uniaxial strain in graphene by Raman spectroscopy: G peak splitting, Gruneisen parameters, and sample orientation

Nicola Marzari

We uncover the constitutive relation of graphene and probe the physics of its optical phonons by studying its Raman spectrum as a function of uniaxial strain. We find that the doubly degenerate E(2g) optical mode splits in two components: one polarized alo ...

Anisotropic memory effects in confined colloidal diffusion

László Forró, Sylvia Jeney, Branimir Lukic

The motion of an optically trapped sphere constrained by the vicinity of a wall is investigated at times where hydrodynamic memory is significant. First, we quantify, in bulk, the influence of confinement arising from the trapping potential on the sphere's ...

Experimental evidence for a two-gap structure of superconducting NbSe2: A specific-heat study in external magnetic fields

Helmuth Berger

To resolve the discrepancies of the superconducting order parameter in quasi-two-dimensional NbSe2, comprehensive specific-heat measurements have been carried out. By analyzing both the zero-field and mixed-state data with magnetic fields perpendicular (H ...
