Acoustic scanning of natural scenes by echolocation in the big brown bat, Eptesicus fuscus
SUMMARY Echolocation allows bats to orient and localize prey in complete darkness. The sonar beam of the big brown bat, Eptesicus fuscus, is directional but broad enough to provide audible echoExpand

Measurements of the sonar beam pattern of flying echolocating bats, Eptesicus fuscus, performing various insect capture tasks in a large laboratory flight room suggest that the axis of the bat father beam is a good index of selective tracking of targets, and in this respect is analogous to gaze in predominantly visual animals.

Echolocating Bats Use a Nearly Time-Optimal Strategy to Intercept Prey
This paper used high speed stereo infra-red videography to study the three dimensional flight paths of the big brown bat, Eptesicus fuscus, as it chased erratically moving insects in a dark laboratory flight room and quantified the bat's complex pursuit trajectories using a simple delay differential equation.

Steering by Hearing: A Bat’s Acoustic Gaze Is Linked to Its Flight Motor Output by a Delayed, Adaptive Linear Law
It is suggested that this adjustable linkage between acoustic gaze and motor output in a flying echolocating bat simplifies the transformation of auditory information to flight motor commands. Expand
Identification and functional characterization of a flax UDP-glycosyltransferase glucosylating secoisolariciresinol (SECO) into secoisolariciresinol monoglucoside (SMG) and diglucoside (SDG)
This study cloned and characterized five flax UGTs and provided evidence that UGT74S1 uses SECO as substrate to form SDG in vitro, allowing us to propose a model for the missing step in SDG lignan biosynthesis. Expand
Sex detection of Carica papaya and Cycas circinalis in pre-flowering stage by ISSR and RAPD
The sex of Carica papaya and Cycas circinalis was studied using ISSR and RAPD techniques in pre-flowering stage, and homology with putative retro elements of diverse plants was revealed, probably indicating its use in the detection of male C.circinalis in future. Expand
Behavioral responses of big brown bats to dives by praying mantises
It is suggested that although the mantis dive can be effective in evading the bat, it does not always deter the bat from continuing pursuit and, given enough altitude, the bat can potentially capture diving prey using the same flight strategy it employs to intercept prey in level flight. Expand
A Strong Constraint to the Joint Processing of Pairs of Cortical Signals
The neurophysiological findings are compared to existing psychophysical data and suggest the intriguing possibility that cortical activity originating at spatial separations greater than ∼1 mm is processed as if by parallel, independent circuits whose signals can be compared against each other but not summed.

Fast and accurate genomic analyses using genome graphs
The human reference genome serves as the foundation for genomics by providing a scaffold for alignment of sequencing reads, but currently only reflects a single consensus haplotype, thus impairingExpand
Fusarium elicitor-dependent calcium influx and associated ros generation in tomato is independent of cell death
Inhibition of ROS generation on two separate occasions such as, calcium-free media and on treatment with inhibitors causing calcium channel occlusion revealed ROS generation as a successive event of calcium influx. Expand
