We derive the capacity region for a broadcast channel with intersymbol interference (ISI) and colored Gaussian noise under an input power constraint. The region is obtained by first defining a similar channel model, the circular broadcast channel, which can be decomposed into a set of parallel degraded broadcast channels. The capacity region for parallel degraded broadcast channels is known. We...

The assembly of silicate and surfactant confined within cylindrical alumina pore channels results in circular hexagonal, concentric lamellar and other unique mesostructures.

Enteric inhibitory motoneurons use nitric oxide and a purine neurotransmitter to relax gastrointestinal smooth muscle. Enteric P/Q-type Ca2+ channels contribute to excitatory neuromuscular transmission; their contribution to inhibitory transmission is less clear. We used the colon from tottering mice (tg/tg, loss of function mutation in the α1A pore-forming subunit of P/Q-type Ca2+ channels) to...

Nitric oxide (NO) hyperpolarizes intestinal smooth muscle cells. This study was designed to determine the mechanism whereby NO activates KCa channels of circular smooth muscle of the rabbit colon. Transmural biopsies of the rabbit colon were stained for NADPH-diaphorase. Freshly dispersed circular smooth muscle cells were studied in the whole cell configuration, as well as in on-cell and excise...

A simple method to fabricate circular microchannels in polydimethylsiloxane (PDMS) is presented and used for facil single cell trapping at low vacuums. A coating of liquid PDMS is applied on the walls of square microchannels, to give them a circular cross section. Diameters ranging from few micrometers to few hundreds of micrometers were achieved. Different coating conditions were systematicall...

This letter investigates electrophoretic molecular communication (EMC) operating in circular duct channels. EMC utilizes the time-varying force that can controllably induce movement of charged particles to enhance performance. In channels, where memory component is high, intersymbol interference (ISI) must be considered. Thus, this presents a method design an electric field under framework calc...

The capacity region of a two-user linear Gaussian compound Multiple Access Channel with common message (CMACC) and intersymbol interference (ISI) under an input power constraint is derived. To obtain the capacity region we first convert the channel to its equivalent memoryless one by defining an n-block memoryless circular Gaussian CMACC model. We then make use of the discrete Fourier transform...
