High-performance microwave oscillators often exploit feedback loop methods such as those that involve a frequency-locked loop (FLL) or a self-injection-locked loop to improve phase noise. This paper ...

Scientists have developed a once-a-day nasal gel formulation for the delivery of insulin that could put an end to injections for Type 1 diabetes sufferers. In results published today in the Royal ...

Several medical conditions can affect the need for B12, as well as a vegan diet.

The response of semiconductor nano-lasers to frequency-modulated optical injection is studied theoretically. Such frequency modulation dynamically changes the detuning between the target slave laser ...
