A highly sensitive microsystem based on nanomechanical biosensors for genomics applications
(Elsevier, 2006)
Microcantilever-based biosensors are a promising tool to detect biomolecular interactions in a direct way with high accuracy. We show the development of a portable biosensor microsystem able to detect nucleic acid hybridization ...

Compact low-power calibration mini-DACs for neural arrays with programmable weights
(Institute of Electrical and Electronics Engineers, 2003)
This paper considers the viability of compact low-resolution low-power mini digital-to-analog converters (mini-DACs) for use in large arrays of neural type cells, where programmable weights are required. Transistors are ...

A spatial contrast retina with on-chip calibration for neuromorphic spike-based AER vision systems
(Institute of Electrical and Electronics Engineers, 2007)
We present a 32 32 pixels contrast retina microchip that provides its output as an address event representation (AER) stream. Spatial contrast is computed as the ratio between pixel photocurrent and a local average between ...

Functional diversity of ectomycorrhizal fungal communities is reduced by trace element contamination
(Elsevier, 2018)
Trait-based approaches are useful tools to explain ecological assembly rules and ecosystem functioning. However, their use for soil microbiota has not been explored in depth yet. We explored trait-based functional changes ...

A neuromorphic cortical-layer microchip for spike-based event processing vision systems
(Institute of Electrical and Electronics Engineers, 2006)
We present a neuromorphic cortical-layer processing microchip for address event representation (AER) spike-based processing systems. The microchip computes 2-D convolutions of video information represented in AER format ...

On algorithmic rate-coded AER generation
(Institute of Electrical and Electronics Engineers, 2006)
This paper addresses the problem of converting a conventional video stream based on sequences of frames into the spike event-based representation known as the address-event-representation (AER). In this paper we concentrate ...

A calibration technique for very low current and compact tunable neuromorphic cells: Application to 5-bit 20nA DACs
(Institute of Electrical and Electronics Engineers, 2008)
Low current applications, like neuromorphic circuits, where operating currents can be as low as a few nanoamperes or less, suffer from huge transistor mismatches, resulting in around or less than 1-bit precisions. Recently, ...

Inhibition of Type 1 Fimbriae-mediated Escherichia Coli Adhesion and Biofilm Formation by Trimeric Cluster Thiomannosides Conjugated to Diamond Nanoparticles
(Royal Society of Chemistry, 2015)
Recent advances in nanotechnology have seen the development of a number of microbiocidal and/or anti-adhesive nanoparticles displaying activity against biofilms. In this work, trimeric thiomannoside clusters conjugated to ...

The Mediating Alliance
(John Wiley & Sons, 2023)
This article proposes the conceptualization of the term “mediating alliance” to further the development of theories about success factors in mediation. Extending Bordin's pan-theoretical conceptualization of the “working ...

Experimental Validation of an Analytical Microdosimetric Model Based on Geant4-DNA Simulations by Using a Silicon-based Microdosimeter
(Elsevier, 2020)
Purpose: To study the agreement between proton microdosimetric distributions measured with a silicon-based cylindrical microdosimeter and a previously published analytical microdosimetric model based on Geant4-DNA in-water ...
