The shunt-series shunt-shunt and shunt-series series-shunt dual feedback amplifiers are demonstrated in this paper using 2-µm GaInP/GaAs HBT technology. The shunt-series shunt-shunt and shunt-series series-shunt wideband amplifiers achieve a small-signal gain of 31/33 dB with the same 3-dB bandwidth of 6 GHz.

Neurosurgery Clinics of North America, 2001
Shunt failure remains a disheartening complication of shunt surgery. The number of adjustable factors in attempting to reduce the rate is small. The clinical presentation and timing of shunt malfunction are well documented. Although the shunt design trials have been negative to date, valves have important effects that have not as yet been translated to

Neurosurgical Review, 2010
Hydrocephalus can be managed successfully with cerebrospinal fluid shunting to extracranial compartments, most commonly the peritoneum. However, current shunt systems are not ideal with high revision rates on long-term follow-up. Draining the cerebrospinal fluid from the cerebral ventricles to the cerebral venous sinuses could mimic the physiological ...

Perhaps one of the most intriguing events in neurosurgical history is the invention and use of the shunt system to treat hydrocephalus, despite the shunt’s high failure rates. The shunt system, classically composed of a proximal catheter, valve, and distal catheter, was developed in the 1950s.

To some extent our greatest problem is the philosophic answer to the question, "who shall be treated, how intensely and to what expense?" The cost of care is almost always greatest in the child who is borderline in selection and least likely to survive.

Six children with shunt nephritis are reported of whom two did not show complete recovery of renal function. Follow up and outcome in relation to the delay in diagnosis and renal biopsy appearances are discussed.
