Adaptation to visuomotor rotation is a particular form of motor learning distinct from force-field adaptation, sequence learning, and skill learning. Nevertheless, study of adaptation to visuomotor rotation has yielded a number of findings and principles that are likely of general importance to procedural learning and memory. First, rotation learning is implicit and appears to proceed through r...

We reports improvements to our Sagnac effect matter-wave interferometer gyroscope. This device now has a short-term rotation-rate sensitivity of 6×10−10 rad s−1 over 1 s of integration, which is the best publicly reported value to date. Stimulated Raman transitions are used to coherently manipulate atoms from counterpropagating thermal beams, forming two interferometers with opposite rotation p...

We introduce a method for estimation of rotation invariant local shape descriptors for 3D models. This method follows a successful idea commonly used to obtain rotation invariant descriptors in 2D images, and improves it by tackling the difficulty of the 3 degrees of freedom that exists in 3D models. Our method is simple, yet it achieves high levels of invariance after rotation transformations,...

need for cognition scale (ncs) is an instrument for assessing individual’s interest to engage in complex thinking activities and consists both long and short forms. the short form of this scale with 18 items has been used in various researches around the world. the objective of this research was to obtain the factor structure of the persian version of ncs (short form) and study of gender differ...

Rotation distance between rooted binary trees measures the number of simple operations it takes to transform one tree into another. There are no known polynomial-time algorithms for computing rotation distance. In this short note, we give an efficient, linear-time approximation algorithm, which estimates the rotation distance, within a provable factor of 2, between ordered rooted binary trees. ...

Short rotation woody crop (SRWC) plantations use fast-growing tree species (such as Populus and Salix) grown under intensively managed conditions much like traditional agricultural crops (Dickmann and Stuart 1983). Typical rotation age ranges from 3-15 years, with the end products including energy and paper (pulp) products. Operational biomass plantations currently use a limited number of clone...

Methods Short axis radially tagged images were acquired at apical and basal levels in 6 healthy subjects. Contouring LV epicardial and endocardial borders is the only user interaction in the twist extraction process. Applying a proper threshold algorithm over the masked images results in binary images containing easily detectable tags. We tracked the mean position of tags over the cardiac cycle...
