Abstract: Increasing the power conversion efficiency of silicon (Si) photovoltaics is a key enabler for continued reductions in the cost of solar electricity. Disclosed herein is a multi-junction photovoltaic cell that does not utilize a conventional interconnection layer and instead places a wide bandgap oxide conductor, for example, a metal oxide such as TiO2, between a top light absorption layer having a relatively large bandgap and a bottom light absorption layer having a relatively small bandgap. The advantageous omission of a conventional interconnection layer between the two subcells is enabled by low contact resistivity between the top and bottom light absorbing layers provided by the wide bandgap oxide conductor. The absence of the conventional interconnect between the subcells significantly reduces both optical losses and processing steps. The disclosed photovoltaic cell may thus enable low-cost, high-efficiency multi-junction devices through less complex manufacturing processes and lower material costs.

Abstract: The present invention relates to a method and system of cybersecurity; and particularly relates to an encryption method and system on the basis of cognitive computing for xenomorphic cryptography or unusual form of cryptography; said method comprises generating a Functional Neural Network or KeyNode (KN) of the system by programming a chain of multiple nodes also called Artificial Mirror Neurons (AMN) based on captured information of reaction time and emotional response to a simple task; racing the nodes in the Functional Neural Network or KeyNode (KN) as an encryption device or cipher for the time of use; generating a password at the time of use based on the sum of intrinsic values of the nodes in the racing network at this time and adopting the generated password for authentication. The present invention can be applied to secure online and mobile communication especially at the dawn of 5G with generalization of open API lifestyle platforms so as to allow real-time identification for digital cryptocurrency payments and other public distributed ledger technology (DLT) mechanisms.

Abstract: A waveguide heater is configured to heat an optical waveguide. The heater includes multiple heating elements and has one or two conditions selected from a group consisting of a first condition and the second condition. The first condition is the heater including multiple interior connectors that are each included in an interior electrical pathway between a pair of the heating elements where the interior connectors are connected in parallel and provide electrical communication between the heating elements included in the pair. The second condition is multiple exterior connectors that are each included in an exterior electrical pathway between electronics and a first one of the heating elements where the exterior connectors are connected in parallel and provide electrical communication between the electronics and the first heating element. The electronics are configured to apply an electrical bias to the heater. In some instances, the heater in included in a wavelength tuner.

Abstract: A heterojunction anode for electrolysis is disclosed. The anode has a first conductive metal oxide (FCMO) layer, a second semiconductor layer contacting the FCMO layer, and one or more islands of a third semiconductor contacting the second semiconductor layer. The FCMO layer may be formed on a metallic base, such as titanium. The FCMO layer may include iridium, the second semiconductor layer may include titanium oxide, and the third semiconductor may include tin oxide. The anode may be manufactured using spray pyrolysis to apply each semiconductor material. The anode may be configured such that when placed in an electrolyte at least a portion of the second semiconductor layer and the islands are in direct physical contact with the electrolyte. The second semiconductor interlayer and third semiconductor islands enhance the production of reactive chlorine in chlorinated water. A water treatment system and method using the anode are also disclosed.

Abstract: A LIDAR system has one or more light splitters and multiple light combiners. The LIDAR system also has multiple optical pathways through which light signals travel. The optical pathways include delay pathways that each extends from one of the one or more splitters to one of the light combiners. The optical pathways include expedited pathways that each extends from one of the splitters to one of the light combiners. Each of the light combiners has one of the delay pathways and one of the expedited pathways extending to the light combiner. The delay pathways and the expedited pathways are configured such that the delay pathway to each light combiner is longer than the expedited pathway to the same light combiner. Each of the delay pathways has a common portion and a separated portion. The common portion of each delay pathway is shared by the other delay pathways. In contrast, the separated portion of a delay pathways is not shared with the other delay pathways.

Abstract: An in vitro method for identifying an anti-cancer agent, the therapeutic efficacy of which is enhanced upon administration with a second agent that increases the expression of OPRK1 and/or BAD, comprising the steps of:



a. co-incubating a population of cells with a target anti-cancer agent and said second agent and
b. measuring the cytotoxicity and/or cytostasis in the population of cells;

wherein the therapeutic efficacy of the target anti-cancer agent is enhanced if the cytotoxicity and/or cytostasis of the target anti-cancer agent is increased compared to a control.
