During rodent active behavior, multiple orofacial sensorimotor behaviors, including sniffing and whisking, display rhythmicity in the theta range (~5-10 Hz). During specific behaviors, these rhythmic patterns interlock, such that execution of individual motor programs becomes dependent on the state of the others. Here we performed simultaneous recordings of the respiratory cycle and ultrasonic ...

This paper presents multiple moving speaker tracking using an 8ch microphone array system installed on a mobile robot. We use a set of Kalman filters with different history lengths in order to track non-linear movements of multiple speakers. For quantitative evaluation of the tracking, motion references of sound sources and a mobile robot, called SIG2, were measured accurately by ultrasonic 3D ...

We describe a time-resolved method for measuring nonlinear ultrasonic phenomena. Current approaches rely on a narrowband measurement of harmonic generation to identify and characterize nonlinearity. Concomitant with these techniques is poor time resolution. We address this limitation with a hybrid narrowband/broadband approach that provides simultaneous time resolution and harmonic isolation fo...

This article addresses the effect of ultrasonication as a pretreatment to anaerobic digestion of four types of animal manure, including swine slurry, beef feedlot manure, dairy manure slurry, and separated dairy manure effluent. The effect of ultrasonication on soluble chemical oxygen demand (SCOD) and biochemical methane potential (BMP) were determined, and the energy efficiency of ultrasonic ...

Echocardiograms were recorded in two patients with suspected aortic root dissection. In the first patient with a massive pulmonary embolus, a simultaneous recording of the mitral ring and posterior aortic wall created a pattern similar to true posterior aortic wall dissection; in the second patient with severe generalized atherosclerosis, thickened aortic walls recorded echocardiographically we...

murmurs were found in most, the only constant abnormality was abnormally wide splitting of the first sound with accentuation of the delayed component. This abnormal sound was thought to be caused by delayed closure of the abnormally large anterior leaflet of the tricuspid valve, especially as its delay was almost exactly related to the degree of right bundle-branch block. Ultrasonic recordingsf...

The simultaneous localization and mapping problem is approached by using an ultrasound sensor and wheel encoders. To account for the low precision inherent in ultrasound sensors, the occupancy grid notion is extended. The extension takes into consideration with which angle the sensor is pointing, to compensate for the issue that an object is not necessarily detectable from all positions due to ...

Medical plants are adapted to different kinds of dormancy to survive in the worst situations. Regarding to ecological viewpoint, this kind of adaptation is very important in respect to restriction of genetic draft and decrease of genetic resource of medicinal plants. This leads to plant survival even after prolonged drought. Since some of them are endangered species and in the other hand increa...
