We trained budgerigars by operant conditioning to discriminate among a set of contact calls in a same-different task and analyzed response latencies from this task by using multidimensional-scaling (MDS) and cluster-analysis procedures. Humans listened to the same calls and indicated the similarity between pairs of calls by a direct rating procedure. An MDS(More)
The Bureau of the Census initially developed the Topologically Integrated Geographic Encoding and Referencing (TIGER) database, a main component of the Master Address File/TIGER System (MAF/TIGER System), to provide geographic services and products in support of the 1990 decennial and other Census Bureau statistical programs. Since its inception, the public(More)
For polycrystalline NiFe/FeMn bilayers, we have observed and quantified the rotation of the pinning direction in the exchange bias training and recovery effects. During consecutive hysteresis loops, the rotation of the pinning direction strongly depends on the magnetization reversal mechanism of the ferromagnet layer. The interfacial uncompensated magnetic(More)
PURPOSE To create a Varian TrueBeam 6 MV FFF Monte Carlo model using BEAMnrc/EGSnrc that accurately reproduces the Varian representative dataset, followed by tuning the model's source parameters to accurately reproduce in-house measurements. METHODS A BEAMnrc TrueBeam model for 6 MV FFF has been created by modifying a validated 6 MV Varian CL21EX model.(More)
