A system and method for transmitting high data rate information from a pulsed radar is disclosed. Also provided is a method for predicting whether a selection of reaction conditions for preparing crosslinked polymer particles will exhibit a potential for forming a gel and a method for predicting whether a selection of reaction conditions will or will not result in the formation of a gel. A first exponential time-constant is determined using curve-fitting from admittance values obtained while the patient is in a sleep posture. The struts are connected to the inverted panels and transfer the shear flow to the mount. Each recording zone including one recording area in the first recording layer and another recording area in the second recording layer which is opposite to the recording area in the first recording layer has a management information recording area for recording management information for recording the record information.
