sfn

SFN is an acronym that can refer to several distinct concepts in technology, science, and academia. Among its most common uses are Single Frequency Network in broadcasting, sulforaphane in biochemistry, and the Society for Neuroscience, which uses the variant SfN in its branding.

A Single Frequency Network is a broadcasting arrangement in which multiple transmitters operate on the same radio frequency and are synchronized in time to provide seamless coverage over a large area. SFNs increase spectral efficiency and reduce interference from neighboring channels when properly coordinated, but they require precise synchronization, timing, and network planning to cope with multipath propagation and edge effects. SFNs are employed in digital radio (DAB), digital television (DVB-T/DVB-T2), and some mobile broadcast services, particularly in regions with strong regional coverage needs and limited available spectrum.

Sulforaphane (SFN) is a naturally occurring isothiocyanate found in cruciferous vegetables such as broccoli, Brussels sprouts, and kale, especially in young broccoli sprouts. It has been studied for potential antioxidant, anti-inflammatory, and anticancer effects, largely through activation of the Nrf2 pathway and the induction of phase II detoxification enzymes. While laboratory and some animal studies are promising, human research yields mixed results and consumption should be viewed as part of a balanced diet rather than a proven therapy.

Society for Neuroscience (SfN) is a major international professional association for scientists who study the nervous system. Founded in 1969 and headquartered in the United States, SfN supports neuroscience research and education, publishes scientific journals, and hosts an annual meeting that brings together researchers from around the world. The organization operates as a hub for networking, policy advocacy, and dissemination of neuroscience knowledge.
