This paper presents an analysis of Cramer-Rao lower bounds (CRLB) in the phase retrieval problem. Previous papers derived Fisher Information Matrices for the phaseless reconstruction setup. Two estimation setups are presented. In the first setup the global phase of the unknown signal is determined by a correlation condition with a fixed reference signal. In the second setup an oracle provides t...

Although the development of collaborative relationships is considered a requirement for medical education, the functioning of these relationships may be impaired by a well-documented social-psychological phenomenon known as group conformity. The authors hypothesized that students would insert a needle into an incorrect location relative to the patella when performing a knee arthrocentesis if th...

The sample consisted of 1,106 registered nurses (RNs), licensed practical nurses (LPNs), and nurses' aides. We conceptualized turnover as a multistage proc...

It is now well established that the anal papillae of culicine larvae secrete salts from the dilute external medium into the body (Koch, 1938; Ramsay, 1953; Stobbart, i960). In the case of the larvae of Aides aegypti the exchange and net transport of sodium through the papillae have been studied in some detail (Treherne, 1954; Stobbart, 1959, i960) and it appears that the sodium pump in the papi...
