Abstract: The present application discloses a device for detecting and reducing radon concentration in an indoor environment. This device comprises at least one radon gas sensor and, at least one differential pressure sensor for measuring the difference between the indoor and outdoor atmospheric pressures, wherein both sensors are connected to a microcontroller configured to perform the pre-processing and aggregation of the data obtained by said sensors. To reduce radon levels, it triggers at least one physical actuator to activate a ventilation device for reducing the radon concentration in an indoor environment when indoor radon concentration is above a first predetermined threshold or when indoor radon concentration is above a second predetermined threshold and the differential pressure is negative.

Abstract: Provided herein are gene repressor systems comprising fusion proteins, such as fusion proteins comprising a DNA binding domain such as a TALE, zinc finger or catalytically-dead CRISPR protein and guide nucleic acid (gRNA), which are useful in the repression of a proprotein convertase subtilisin kexin Type 9 (PCSK9) gene. Also provided are methods of using such systems to repress transcription of PCSK9.

Abstract: A method for processing a signal on board an aircraft. An electronic control unit receives an input signal including useful data in a first passband, implements a first operation of bandpass filtering the input signal with a first passband to obtain a useful signal containing the useful data, with detection of interference caused by a lightning strike. The electronic control unit implements a second operation of bandpass filtering the input signal to obtain a detection signal, the bandpass filter having a second passband that is distinct from the first passband, comparing a detection value derived from the detection signal with a detection threshold, and correcting the exploitation of the useful data if exceeded.
