An Integer Linear Programming Model to Optimize Coding DNA Sequences By Joint Control of Transcript Indicators

A Coding DNA Sequence (CDS) is a fraction of DNA whose nucleotides are grouped into consecutive triplets called codons, each one encoding an amino acid. Because most amino acids can be encoded by more than one codon, the same amino acid chain can be obtained by a very large number of different CDSs. These synonymous CDSs show different features that, also depending on the organism the transcript is expressed in, could affect translational efficiency and yield. The identification of optimal CD...

Fast-Response Paradigm of Si Photodiode Array to Increase the Effective Sensitive Area of Detectors in Wireless Optical Biotelemetry Links

Live Demonstration: Event-Driven Serial Communication on Optical Fiber

This demonstration presents the first implementation of “event-driven” serial asynchronous communication on optical fiber. “event-driven” communication is used by neuro-morphic sensors, that sample the sensory signal when the signal itself changes of a given amount. This type of sensing adapts to the dynamics of the input itself, achieving at the same time extremely high temporal resolution (when needed), low latency and signal compression. To apply this technology in robotics, optical commun...

A Novel Light-to-Frequency Converter Based Analog Front-End for Optical Sensing Applications

This paper reports on a novel light-to-frequency converter circuit based on the variation of the internal junction capacitance of a Si-photodiode under light illumination of its sensitive area. In particular, the proposed analog front-end circuit is capable of measuring light intensity variations by providing the frequency modulation of a square wave output voltage signal. Thus, this solution allows for a quasi-digital output that can be measured using simple digital frequency meters, avoidin...
