Many biological effects of exposure to extremely low frequency electromagnetic fields(ELF-EMFs) have been documented, but little work carried out on plants. A meiotic study wasperformed on Brassica napus L as C3 plant and Zea mays L as a C4 plant exposed to electromagneticfields. Our investigations were focused on plants grown from wet pretreated seeds with3 and 10 mT for a 4 h exposure time an...

this study was carried out to investigate the effect of selection on the reduction of fat-tail size in lori-bakhtiari lambs. the study lasted for five years at the development and breeding center of lori-bakhtiari sheep station. estimation of fat-tail weight, using external fat-tail dimensions was obtained from regression procedure at 6 month age. soft tissue depth at the point 12 cm from the m...

Structure from Motion (SfM) algorithms take as input multiview stereo images (along with internal calibration information) and yield a 3D point cloud and camera orientations/poses in a common 3D coordinate system. In the case of an incremental SfM pipeline, the process requires repeated model estimations based on detected feature points: homography, fundamental and essential matrices, as well a...

Matrix factorization is a fundamental building block in many computer vision and machine learning algorithms. In this work we focus on the problem of ”structure from motion” in which one wishes to recover the camera motion and the 3D coordinates of certain points given their 2D locations. This problem may be reduced to a low rank factorization problem. When all the 2D locations are known, singu...

The effects of stress are frequently studied, yet its proximal causes remain unclear. Here we demonstrate that subjective estimates of uncertainty predict the dynamics of subjective and physiological stress responses. Subjects learned a probabilistic mapping between visual stimuli and electric shocks. Salivary cortisol confirmed that our stressor elicited changes in endocrine activity. Using a ...
