We present a simple and realistic model of the circadian pacemaker that can be interpreted in molecular terms. The model, which consists of a single time-delay differential equation, simulates the expression of a generic clock protein that inhibits its own expression through a feedback mechanism. Despite its simplicity, this model fulfils most of the(More)
—The numerous advantages of single-frequency networks (SFNs) make them one of the preferred deployment options for digital video broadcasting terrestrial (DVB-T) operators. However, SFNs are exposed to self-interference that may reduce the effective coverage. This work deals with the optimal adjustment of internal delays at the transmitters to minimize(More)
—Maintaining multiple wireless connections is a promising solution to boost capacity in fifth-generation (5G) networks , where user equipment is able to consume radio resources of several serving cells simultaneously and potentially aggregate bandwidth across all of them. The emerging dual connectivity paradigm can be regarded as an attractive access(More)
