    Abstract: A solar cell for collecting solar radiation can include a barrier layer such as a dielectric barrier layer and a heterostructure including a first light absorbing layer and at least a second light absorbing layer. A method for forming the solar cell can include forming a sacrificial layer on a support substrate and forming the barrier layer on the sacrificial layer. The barrier layer is formed to have a strain gradient through its thickness. The heterostructure is attached to the barrier layer and the sacrificial layer is removed, thereby separating the barrier layer and the heterostructure from the support substrate. During the removal of the sacrificial layer, the strain gradient causes the barrier layer and heterostructure, to roll, curl, or spiral, thereby resulting in a radially stacked heterostructure that provides a light concentrating optical cavity having multiple light absorbing layers with different band gaps.

    Abstract: Teams of robots can be organized to collectively complete complex real-world tasks, for example collective foraging in which robots search for, pick up, and drop off targets in a collection zone. A dynamic multiple-place foraging algorithm (MPFAdynamic) is a scalable, flexible, and efficient algorithm for robot swarms to collect objects in unmapped environments. It achieves scalability through a decentralized architecture in which robots search without central control, and then return to mobile depots which provide collection and communication points. Mobile depots move closer to clusters of targets as robots discover them, which reduces robot transport time as well as collisions among robots. Flexibility is achieved by incorporating individual robot behaviors in which robots move and communicate in ways that mimic the foraging behaviors of ants. The MPFAdynamic algorithm demonstrates that dispersed agents that dynamically adapt to local information in their environment provide more flexible and scalable swarms.

    Abstract: Systems and methods implementing a resonance circuit, including an avalanche photodiode, in which a resonance frequency of the resonance circuit is matched with the frequency of a dynamic biasing signal of the avalanche photodiode, can be used in a variety of applications. In various embodiments, a method for blocking and/or compensating current injection associated with the parasitic capacitance of APDs operated under dynamic biasing may be substantially realized by the matching of the resonance frequency of a resonance circuit including the avalanche photodiode with the frequency of an applied dynamic biasing signal. Additional systems and methods are described that can be used in a variety of applications.

    Abstract: This disclosure describes modular miRNA regulator molecules and methods of using modular miRNA regulator molecules. Generally, the modular miRNA regulator molecules include a recognition module and an inhibition module. Generally, the recognition module includes a polynucleotide in which at least a portion of the polynucleotide recognizes at least a portion of a preselected pre-miRNA. Generally, the inhibition module includes a moiety that inhibits nuclease processing of the preselected pre-RNA to a mature RNA.

    Abstract: Multiple sources of reviews for the same product or service (e.g. hotels, restaurants, clinics, hair saloon, etc.) are utilized to provide a trustworthiness score. Such a score can clearly identify hotels with evidence of review manipulation, omission and fakery and provide the user with a comprehensive understanding of the reviews of a product or establishment. Three types of information are used in computing the score: spatial, temporal and network or graph-based. The information is blended to produce a representative set of features that can reliably produce the trustworthiness score. The invention is self-adapting to new reviews and sites. The invention also includes a validation mechanism by crowd-sourcing and fake review generation to ensure reliability and trustworthiness of the scoring.
