Guastavino design of the 1909 thin brick dome of the Cathedral of St John the Divine.

In 1909, Rafael Guastavino Jr. designed the 93-foot-wide dome of the Cathedral of St John the Divine, Harlem, NY. As the thinnest brick shell in the world, the dome is also a clear example of construction efficiency and material optimization. This paper re ...

Horava Gravity is Asymptotically Free in 2+1 Dimensions

Sergey Sibiryakov, Diego Blas Temino, Mario Herrero Valea

We compute the beta functions of marginal couplings in projectable Horava gravity in 2 + 1 spacetime dimensions. We show that the renormalization group flow has an asymptotically free fixed point in the ultraviolet (UV), establishing the theory as a UV-com ...

Rabi oscillation in a quantum cavity: Markovian and non-Markovian dynamics

Alexandre Roulet, Pierre-Olivier Guimond

We investigate the Rabi oscillation of an atom placed inside a quantum cavity where each mirror is formed by a chain of atoms trapped near a one-dimensional waveguide. This proposal was studied previously with the use of Markov approximation, where the del ...

On constraining the speed of gravitational waves following GW150914

Sergey Sibiryakov, Diego Blas Temino, Mikhail Ivanov

We point out that the observed time delay between the detection of the signal at the Hanford and Livingston LIGO sites from the gravitational wave event GW150914 places an upper bound on the speed of propagation of gravitational waves, c (gw) ae(2) 1.7 in ...

Accelerated Spectral Clustering Using Graph Filtering of Random Signals

Pierre Vandergheynst, Rémi Gribonval, Gilles Puy, Nicolas Tremblay

We build upon recent advances in graph signal processing to propose a faster spectral clustering algorithm. Indeed, classical spectral clustering is based on the computation of the first

Asymmetric breaking size-segregation waves in dense granular free-surface flows

Christophe Ancey, Kasper van der Vaart

Debris and pyroclastic flows often have bouldery flow fronts, which act as a natural dam resisting further advance. Counter intuitively, these resistive fronts can lead to enhanced run-out, because they can be shouldered aside to form static levees that se ...

Sputtered Cu-polyethylene films inducing bacteria inactivation in the dark and under low intensity sunlight

César Pulgarin, Juan Kiwi, Sami Rtimi, Oualid Baghriche, Laura Victoria Suárez Murillo

This study addresses the preparation of uniform, adhesive and robust thin Cu-polyethylene films (PE-CuOx) by direct current magnetron sputtering (DCMS). Cu-coatings of 25 nm sputtered with 60W deposited 0.16% weight Cu/weight PE leading to the fastest bact ...

Observation device with optical compensation

Philippe Renaud, Yann Barrandon, David Vincent Bonzon, David Forchelet, Steve Béguin

The invention concerns an observation device such as cell culture wells comprising an optical element such as a lens or a filter, or even combinations thereof, for compensating an optical effect induced on a sample contained in the observation device and i ...

Completing Lorentz violating massive gravity at high energies

Sergey Sibiryakov, Diego Blas Temino

Theories with massive gravitons are interesting for a variety of physical applications, ranging from cosmological phenomena to holographic modeling of condensed matter systems. To date, they have been formulated as effective field theories with a cutoff pr ...
