Bat biology

Replication in field biology: the case of the frog-eating bat.

Studies conducted in the field offer unique opportunities to observe nature, but achieving true replication under natural conditions is challenging. As demonstrated by the discovery of frog eating by a charismatic bat, biology conducted in the field generally follows an interesting progression that includes discovery, demonstration, experimentation, and verification.

Pallid Bat

The pallid bat (Antrozous pallidus) is the second largest bat in Washington. The species ranges from central Mexico northward through western Texas, New Mexico, Arizona, southern and western Colorado, south-central Utah, western Nevada, California, Oregon, eastern Washington, western Idaho, and north to the southern Okanagan Valley of British Columbia (Orr 1954, Shryer and Flath 1980, Hermanson...

Bat Ecology

Bat flight

dramatically between cancer types. However, the question of whether these differences represent changes in the frequency of chromothripsis between different cell types or changes in the ability of different cell types to survive chromothripsis remains unclear. Finally, additional work will be required to identify the time at which chromothripsis occurs. The micronucleus model of chromothripsis ...

A New Bat Based Back-Propagation (BAT-BP) Algorithm

Metaheuristic algorithm such as BAT algorithm is becoming a popular method in solving many hard optimization problems. This paper investigates the use of Bat algorithm in combination with Back-propagation neural network (BPNN) algorithm to solve the local minima problem in gradient descent trajectory and to increase the convergence rate. The performance of the proposed Bat based Back-Propagatio...
