Abstract: In one aspect, organic-inorganic nanoparticle compositions are described herein comprising engineered surfaces which, in some embodiments, reduce non-radiative recombination mechanisms, thereby providing optoelectronic devices with enhanced efficiencies. In some embodiments, a nanoparticle composition comprises a layer of organic-inorganic perovskite nanocrystals, the organic-inorganic perovskite nanocrystals comprising surfaces associated with growth passivation ligands and trap passivation ligands, wherein the growth passivation ligands are larger than the trap passivation ligands and are of size unable to incorporate into octahedral corner sites of the perovskite crystal structure.

Abstract: According to various embodiments, a method for reducing heading error in a magnetometer that uses Rb-87 atoms is disclosed. The method includes varying a direction and magnitude of a magnetic field at different spin polarization regimes. According to various embodiments, a magnetometer adapted for reduced heading error is disclosed. The magnetometer includes a multipass cell containing Rb-87 vapor, a pump laser operated in a pulse mode that is synchronous with a Larmor frequency, and two orthogonal probe lasers configured to rotate to vary a direction and magnitude of a magnetic field at different spin polarization regimes.

Abstract: Systems and methods are provided trajectory prediction that leverages game-theory to improve coverage of multi-modal predictions. Examples of the systems and methods include obtaining training data including first trajectories for a first plurality of agent devices and first map information of a first environment for a past time horizon and applying the training data to a game-theoretic mode-finding algorithm to generate a mode-finding model for each agent device that predicts modes of the first trajectories. A trajectory prediction model can be trained on the predicted modes as a coverage loss term between predicted modes. Future trajectories can be predicted for a second plurality of agent devices based on applying observed data to the trajectory prediction model. A control signal can then be generated to effectuate an autonomous driving command on an agent device of the second plurality of agent devices based on the predicted future trajectories.

Abstract: Disclosed is a system and method for the controlled clustering of gene regulatory proteins at the specific target genomic loci. The technology enables formation of liquid-like droplets closely interfaced with genome organization. This technology can be utilized for perturbing endogenous nuclear structures as well as nucleating synthetic membrane-less assemblies. The technology can also be utilized for inducing or detecting mechanical stresses within the genome.
