Integrated elastomer-based device for measuring the mechanics of adherent cell monolayers

Herbert Shea, Cristina Martin Olmos, Alexandre Poulin, Francesca Sorba

Cells in the body collectively sustain mechanical deformations in almost all physiological functions. From the morphogenesis stage, cells' ability to sustain stress is essential for the body's well-being. Several pathologies have been associated with abnor ...

Local tuning of fused silica thermal expansion coefficient using femtosecond laser

Yves Bellouard, Pieter Vlugter, Erica Kathleen Block

Femtosecond laser exposure of fused silica in the nonablative regime can lead to various localized bulk modifications of the material structure. In this paper, we show that these laser-induced modifications can be used to tune silica thermal expansion prop ...

Reconstruction and simulation of neocortical microcircuitry

Henry Markram, Felix Schürmann, Sean Lewis Hill, Eilif Benjamin Muller

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for reconstructing and simulating neocortical microcircuitry. In one aspect, a method includes providing a model of neural tissue, the model including differ ...

Microfabrication of curved sidewall grooves using scanning nanosecond excimer laser ablation

Patrik Willi Hoffmann, Josef Andreas Schuler, Georgios Violakis, André Gabriel Kostro, Jing Gong

Novel glazing with embedded micro-mirrors can significantly reduce the energy consumption due to cooling and lighting in buildings. Especially promising are large arrays of periodic micro compound-parabolic-concentrators (CPCs) with angular-selected transm ...

Assessing microlens quality based on 3D irradiance measurement at the focal spot area

Toralf Scharf, Wilfried Noell, Jeremy Béguelin, Michail Symeonidis

During the fabrication process of microlenses, characterization is essential for two purposes: evaluate the optical quality of the element and provide surface information feedback for process optimization. However, no technique can fulfill these two object ...

Design Guidelines for High-Performance SCM Hierarchies

Babak Falsafi, Edouard Bugnion, Javier Picorel Obando, Alexandros Daglis, Mark Johnathon Sutherland, Dmitrii Ustiugov

With emerging storage-class memory (SCM) nearing commercialization, there is evidence that it will deliver the much-anticipated high density and access latencies within only a fewfactors of DRAM. Nevertheless, the latency-sensitive nature of memory-residen ...

All-optically induced quasi phase matching in SiN waveguides for second harmonic generation enhancement

Tobias Kippenberg, Camille Sophie Brès, Martin Hubert Peter Pfeiffer, Davide Grassani, Svyatoslav Kharitonov, Adrien Billat

We report more than 30dB second harmonic generation enhancement in SiN waveguide by all-optical writing of a persistent χ(2) grating. Phase matching peaks are observed for different writing wavelengths. ...

Deep Cfht Y-Band Imaging Of Vvds-F22 Field. I. Data Products And Photometric Redshifts

Huanyuan Shan

We present our deep Y-band imaging data of a two square degree field within the F22 region of the VIMOS VLT Deep Survey. The observations were conducted using the WIRCam instrument mounted at the Canada-France-Hawaii Telescope (CFHT). The total on-sky time ...

On the Limits of Precision Glass Molding for Diffractive Optical Elements

Karin Prater

Diffractive optical elements (DOEs) consist of surface reliefs with dimensions in the micrometer range and nanometer precision. Two technologies dominate: Elements replicated in plastic and directly microfabricated elements in fused silica. Plastic DOEs ar ...

Coexistence of Multiple Nonlinear States in a Tristable Passive Kerr Resonator

Miles Henry Anderson

Passive Kerr cavities driven by coherent laser fields display a rich landscape of nonlinear physics, including bistability, pattern formation, and localized dissipative structures (solitons). Their conceptual simplicity has for several decades offered an u ...
