Abstract: In one aspect, compounds and associated pharmaceutical compositions are described herein comprising isolated cannabicitran (CBT-C (3)). In some embodiments, CBT-C (3) enantiomers are isolated and/or prepared. In some further embodiments, the biological activity of enantiomers are determined. In some further embodiments, one or more enantiomers may be incorporated into a composition.

Abstract: Various embodiments relate generally to electrical and electronic hardware, computer software, wired and wireless network communications, and computing devices, including mobile and wearable computing devices, and more specifically, to devices and techniques for assessing affective states of a user based on data derived from, for example, a wearable computing device. In one embodiment, an apparatus including a wearable housing configured to couple to a portion of a limb at its distal end, a subset of physiological sensors and a processor configured to execute instructions configured to calculate a portion of an intensity associated with an affective state for each of the physiological, form an intensity value based on the portions of the intensity and determine a polarity value of the intensity value. The apparatus is further configured to determine the affective state, for example, as a function of the intensity value and the polarity value of the intensity value.

Abstract: A method of estimating the angles of arrival .theta.1 and .theta.2 of two closely spaced radar targets of which one target may be the virtual image of the other target. The targets are illuminated with a radar beam of wavelength WL, and the resulting echos from the targets are received at three directive antennas whose apertures are coplanar and whose phase centers are colinear and spaced a distance D apart. The received echos are converted to complex numbers S1, S2 and S3 representing the magnitude and phase of the respective echos received by the three directive antennas. If the plane of symmetry of the two targets is known, the value of a parameter WD is determined which minimizes L=.vertline.S1-WB(WD+WD*)S2+WB.sup.2 S3.vertline..sup.2, where WB=exp (j2.pi.D.theta.B/WL) and .theta.B is the known angle bisecting the angles of arrival of the two targets. If the plane of symmetry of the two targets is not known, the values of WD and WB are determined by solving for WD and WB which minimize L.
