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 ...

Sedimentological and geomorphological imprints of Holocene tsunamis in southwestern Spain: An approach to establish the recurrence period
(Elsevier, 2013)
This paper reviews the sedimentological and geomorphological imprints of prehistoric and historical tsunamis in the four main estuaries of SW Spain. These imprints include beach erosion, filling of intertidal channels, ...

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 ...
