High-Precision MRI Reconstruction Algorithm for 3D Sphere Packings

Daniele Mari, Arnaud Comment, Riccardo Balzan, Alessandro Luigi Sellerio

Packings of granular materials are complex systems consisting of large sets of particles interacting via contact forces. Their internal structure is interesting for several theoretical and practical reasons, especially when the model system consists in a l ...

The TORCH PMT: a close packing, multi-anode, long life MCP-PMT for Cherenkov applications

Christoph Frei

Photek (U.K.) and the TORCH collaboration are undertaking a three year development program to produce a novel square MCP-PMT for single photon detection. The TORCH detector aims to provide particle identification in the 2-10 GeV/c momentum range, using a T ...

Dynamics and Correlations among Soft Excitations in Marginally Stable Glasses

Matthieu Wyart, Marco Baity-Jesi, Markus Müller

Marginal stability is the notion that stability is achieved, but only barely so. This property constrains the ensemble of configurations explored at low temperature in a variety of systems, including spin, electron, and structural glasses. A key feature of ...

Continuum percolation of polydisperse hyperspheres in infinite dimensions

Claudio Grimaldi

We analyze the critical connectivity of systems of penetrable d-dimensional spheres having size distributions in terms of weighed random geometrical graphs, in which vertex coordinates correspond to random positions of the sphere centers, and edges are for ...

In-situ mapping of the molecular arrangement of amphiphilic dye molecules at the TiO2 surface of dye sensitized solar cells

Ursula Röthlisberger, Francesco Stellacci, Ivano Tavernelli, Nicolas Tétreault, Kislon Voitchovsky, Negar Ashari Astani, Hauke Arne Harms

Amphiphilic sensitizers are central to the function of dye-sensitized solar cells. It is known that the cells performance depends on the molecular arrangement and the density of the dye on the semiconductor surface, but a molecular-level picture of the cel ...

Bending Rules in Graphene Kirigami

The three-dimensional shapes of graphene sheets produced by nanoscale cut-and-join kirigami are studied by combining large-scale atomistic simulations with continuum elastic modeling. Lattice segments are selectively removed from a graphene sheet, and the ...

Interplay of Packing and Flip-flop in Local Bilayer Deformation. How Phosphatidylglycerol Could Rescue Mitochondrial Function in a Cardiolipin-deficient Yeast Mutant

Anne-Florence Raphaëlle Bitbol, Mohammad Rahimi

In a previous work, we have shown that a spatially localized transmembrane pH gradient, produced by acid micro-injection near the external side of cardiolipin-containing giant unilamellar vesicles, leads to the formation of tubules that retract after the d ...

Sagittal plane blocade in patients with Functional Hallux Limitus:a multisegment model analysis of the Flexor Hallucis Longus endoscopic tenolysis

Kamiar Aminian, Arash Arami, Hossein Rouhani

Functional Hallux Limitus (FHL) is a relatively unknown clinical entity in which dorsal flexion of the first metatarsophalangeal joint is restricted during final stance phase, derailing the three mechanisms of foot stabilization 1. The close packing of the ...

Impact of heterocirculene molecular symmetry upon two-dimensional

Despite the development of crystal engineering, it remains a great challenge to predict the crystal structure even for the simplest molecules, and a clear link between molecular and crystal symmetry is missing in general. Here we demonstrate that the two-d ...

Optical Mirror from Laser-Trapped Mesoscopic Particles

Johann Rohner, Jean-Marc Fournier

Trapping of mesoscopic particles by optical forces usually relies on the gradient force, whereby particles are attracted into optical wells formed by landscaping the intensity of an optical field. This is most often achieved by optical Gaussian beams, inte ...
