Transition-metal dioxides: A case for the intersite term in Hubbard-model functionals

Triatomic transition-metal oxides in the "inserted dioxide" (O-M-O) structure represent one of the simplest examples of systems that undergo qualitative geometrical changes via subtle electronic-structure modulation. We consider here three transition-metal ...

Tandem collimators for the JET tangential gamma-ray spectrometer

Patrick Blanchard

The tangential gamma-ray spectrometer (TGRS) of the JET tokamak fusion facility is an important diagnostics for investigating the fast particle evolution. A well defined field of view for the TGRS diagnostics is essential for its proper operation and this ...

Lower Bounds on the Area Requirements of Series-Parallel Graphs

Fabrizio Frati

We show that there exist series-parallel graphs requiring Omega(n2(root log n)) area in any straight-line or poly-line grid drawing. Such a result is achieved in two steps. First, we show that, in any straight-line or poly-line drawing of K-2,K-n, one side ...

On the connectivity of visibility graphs

The visibility graph of a finite set of points in the plane has the points as vertices and an edge between two vertices if the line segment between them contains no other points. This paper establishes bounds on the edge- and vertex-connectivity of visibil ...

Brivanib, a Dual FGF/VEGF Inhibitor, Is Active Both First and Second Line against Mouse Pancreatic Neuroendocrine Tumors Developing Adaptive/Evasive Resistance to VEGF Inhibition

Douglas Hanahan, Elizabeth Anne Allen

Purpose: Preclinical trials of a mouse model of pancreatic neuroendocrine tumors (PNET) were conducted to determine whether dual FGF/VEGF pathway inhibition with brivanib can improve first-line efficacy in comparison with VEGF inhibitors lacking fibroblast ...

High-throughput nanofabrication of plasmonic structures and metamaterials with high resolution nanostencil lithography

Hatice Altug, Serap Aksu, Min Huang

We demonstrate a novel fabrication approach for high-throughput fabrication of engineered plasmonic antenna arrays and metamaterials with Nanostencil Lithography (NSL). NSL technique, relying on deposition of materials through a shadow mask, offers the fle ...

Universal amplitudes of the Casimir-like interactions between four types of rods in fluid membranes

Anne-Florence Raphaëlle Bitbol

The fluctuation-induced, Casimir-like interaction between two parallel rods of length L adsorbed on a fluid membrane is calculated analytically at short separations d < L. The rods are modeled as constraints imposed on the membrane curvature along a strai ...

An Interactive Expert System for Daylighting Design Exploration

Marilyne Andersen

Architects increasingly use digital tools during the design process, particularly as they approach such complex problems as designing for successful daylighting performance. However, while simulation tools may provide the designer with valuable information ...

Individual particle handling in a microfluidic system based on parallel laser trapping

René Salathé, Horst Vogel, Peter Ryser, Michael Werner, Bastien Rachet, Mathieu Grossenbacher

We present an optical trapping system combining individually addressable multiple laser traps with fluorescence spectroscopy. An in-line set of 64 near-IR laser diodes is used to create a line of individually addressable traps inside a microfluidic chip. T ...

Parametric free-form shape design with PDE models and reduced basis method

Gianluigi Rozza, Toni Mikael Lassila

We present a coupling of the reduced basis methods and free-form deformations for shape optimization and design of systems modelled by elliptic PDEs. The free-form deformations give a parameterization of the shape that is independent of the mesh, the initi ...
