In-Sensor Passive Speech Classification with Phononic Metamaterials

Luis Guillermo Villanueva Torrijo, Daniel Moreno Garcia

Mitigating the energy requirements of artificial intelligence requires novel physical substrates for computation. Phononic metamaterials have vanishingly low power dissipation and hence are a prime candidate for green, always-on computers. However, their u ...

Small-scale dynamo with finite correlation times

Salim Bennouna

Fluctuation dynamos occur in most turbulent plasmas in astrophysics and are the prime candidates for amplifying and maintaining cosmic magnetic fields. A few analytical models exist to describe their behavior, but they are based on simplifying assumptions. ...

The accreted nuclear clusters of the Milky Way

Carmela Lardo

A number of the massive clusters in the halo, bulge, and disc of the Galaxy are not genuine globular clusters (GCs) but instead are different beasts altogether. They are the remnant nuclear star clusters (NSCs) of ancient galaxies since accreted by the Mil ...

Clustering and control for adaptation uncovers time-warped spike time patterns in cortical networks in vivo

James Bryden Isbister

How information in the nervous system is encoded by patterns of action potentials (i.e. spikes) remains an open question. Multi-neuron patterns of single spikes are a prime candidate for spike time encoding but their temporal variability requires further c ...

Chromate tolerance and removal of bacterial strains isolated from uncontaminated and chromium-polluted environments

Rizlan Bernier-Latmani, Zuzana Chromiková

Investigation of bacterial chromate tolerance has mostly focused on strains originating from polluted sites. In the present study, we isolated 33 chromate tolerant strains from diverse environments harbouring varying concentrations of chromium (Cr). All of ...

High-temperature copolyamides obtained by the efficient transamidation of crystalline-crystalline polyamide blends

Véronique Michaud, John Christopher Plummer, Holger Frauenrath, Sylvain Cyril Claude Galland

High-performance thermoplastic composites based on semiaromatic polyamides are prime candidates for metal replacement in lightweight structural applications. However, the low ductility and toughness of semiaromatic polyamides remain major obstacles to thei ...

Hyperdimensional computing for blind and one-shot classification of EEG error-related potentials

José del Rocio Millán Ruiz

The mathematical properties of high-dimensional (HD) spaces show remarkable agreement with behaviors controlled by the brain. Computing with HD vectors, referred to as “hypervectors,” is a brain-inspired alternative to computing with numbers. HD computing ...

Hyperdimensional computing for noninvasive brain-computer interfaces: Blind and one-shot classification of EEG error-related potentials

José del Rocio Millán Ruiz

The mathematical properties of high-dimensional (HD) spaces show remarkable agreement with behaviors controlled by the brain. Computing with HD vectors, referred to as "hypervectors," is a brain-inspired alternative to computing with numbers. HD computing ...

Recent Progress in Wafer-Fused VCSELs Emitting in the 1550-nm Band

Elyahou Kapon, Alexandru Mereuta, Alexei Sirbu, Vladimir Iakovlev, Andrei Caliman, Grigore Suruceanu

Record-high fundamental mode output power of 1.5 mW at 100 degrees C is achieved with InAlGaAs-InP/AlGaAs-GaAs 1550 nm wavelength vertical cavity surface emitting lasers (VCSELs) produced by a modified wafer fusion technique. A broad wavelength setting on ...

Fast Single-Photon Avalanche Diode Arrays for Laser Raman Spectroscopy

Edoardo Charbon

We incorporate newly developed solid-state detector technology into time-resolved laser Raman spectroscopy, demonstrating the ability to distinguish spectra from Raman and fluorescence processes. As a proof of concept, we show fluorescence rejection on hig ...

Material Classification Using Color and NIR Images

Sabine Süsstrunk, Neda Salamati

Material classification is becoming more important in computer vision and digital photography applications, which require accurate classification of objects present in the imaged scene. This is a very challenging task because the sheer diversity of scene c ...

Metal-organic coordination interactions in Fe-Terephthalic acid networks on Cu(100)

Klaus Kern

Metal-organic coordination interactions are prime candidates for the formation of self-assembled, nanometer-scale periodic networks with room-temperature structural stability. We present X-ray photoelectron spectroscopy measurements of such networks at the ...

Delta-like 4 is the essential, nonredundant ligand for Notch1 during thymic T cell lineage commitment

Freddy Radtke, Ute Koch

Thymic T cell lineage commitment is dependent on Notch1 (N1) receptor-mediated signaling. Although the physiological ligands that interact with N1 expressed on thymic precursors are currently unknown, in vitro culture systems point to Delta-like 1 (DL1) an ...

A Single Photon Avalanche Diode Array Fabricated in 0.35um CMOS and based on an Event-Driven Readout for TCSPC Experiments

Edoardo Charbon, Cristiano Niclass

The design and characterization of an imaging sensor based on single photon avalanche diodes is presented. The sensor was fully integrated in a 0.35µm CMOS technology. The core of the imager is an array of 4x112 pixels that independently and simultaneously ...
