We consider the state estimation of a maneuvering target in 3D using bearing and elevation measurements from a passive infrared search and track (IRST) sensor.Since the range is not observable, the sensor must perform a maneuver to observe the state of the target.The target moves with a nearly constant turn (NCT) in the XY-plane and nearly constant
The Mottled Owl (Ciccaba virgata) is a common species in the Neotropics.Despite this, their reproductive behavior is not completely known.Here I describe the nest of this owl on the ground, registered in Grecia town, Costa Rica.The nest had two white eggs in a natural cavity on the ground, near a stream.During a second visit, two months later, I re
Peripheral light harvesting complex (LH2), which is found in photosynthetic antenna systems of purple photosynthetic bacteria, has important functions in the photosynthetic process, such as harvesting sunlight and transferring its energy to the photosynthetic reaction center.The key component in excitation energy transfer (EET) between LH2s is B850
Abstract Background Is this person ill or just old? This question reflects the pondering mind of a doctor while interpreting the complaints of an elderly person who seeks his help.Many doctors think that ageing is a non-disease.Accordingly, various attempts have been undertaken to separate pathological ageing from normal ageing.However, the existen
