A simple microcontroller based digital lock-in amplifier for the detection of low level optical signals [PDF]
, 2002 Traditionally digital lock-in amplifiers sample the input signal at a rate much higher than the lock-in reference frequency and perform the lock-in algorithm with high-speed processors.

Open-ended evolution to discover analogue circuits for beyond conventional applications [PDF]
, 2012 Analogue circuits synthesised by means of open-ended evolutionary algorithms often have unconventional designs. However, these circuits are typically highly compact, and the general nature of the evolutionary search methodology allows such designs to be ...

Unconstrained evolution of close-to-ideal "LCR" low-pass filter [PDF]
The unconstrained evolution has already been applied in the past towards design of digital circuits, and extraordinary results have been obtained, including generation of more compact circuits with smaller number of electronic components.

Optical black hole lasers [PDF]
, 2012 Using numerical simulations we show how to realise an optical black hole laser, i.e. an amplifier formed by travelling refractive index perturbations arranged so as to trap light between a white and a black hole horizon.

Design method for monolithic analogue filters
Electronics Letters, 1978 A new concept, compatible with m.o.s. or bipolar technology, for the design of monolithic analogue active filters is proposed. The method uses only ratioed capacitors as passive components and is especially suitable for the implementation of high-frequency filters.

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

An HDTV encoder for PALplus transmissions, supplemented with a digital residual signal [PDF]
, 1996 This paper discusses the design of a video encoder which will enable PALplus compatible HDTV transmission, by embedding a digital residual component within the standard analogue PALplus television signal.
