A wideband CPW ring power combiner with low insertion loss and high port isolation [PDF]
, 2012 In this paper we present a coplanar waveguide (CPW)-based ring power combiner that exhibits less than 0.8 dB insertion loss, better than 15 dB port match and higher than 22 dB isolation loss over the frequency range from 50 GHz to 100 GHz.

Isolation for high-risk patients [PDF]
Postgraduate Medical Journal, 1976 Summary Standard isolation accommodation provides adequate protection against the infectious diseases prevalent in the U.K. but higher standards are necessary for more dangerous infections imported from overseas. These may be provided reasonably cheaply by modifying existing wards but staff are still exposed to risk.

Adaptation to social isolation Acute and long-term stress responses of growing gilts with different coping characteristics [PDF]
, 2001 The present experiment studied the acute and long-term stress responses of reactive and proactive prepubertal gilts to social isolation. Gilts with either reactive or proactive features were identified according to behavioral resistance in a backtest at ...
