Application number: 17/617,438

Abstract:
An exemplary clustering and computation reuse method comprises providing an artificial convolutional neural network; detecting that neuron vectors associated with an input layer and/or a hidden layer of the convolutional neural network are similar to one another; detecting similarities among the neuron vectors associated with the input layer and/or the at least one hidden layer during execution of a computer program; clustering similar neuron vectors into groups; computing a centroid vector for each group; performing, by a computer processor, computations using the centroid vector associated with one of the groups as a representative for one of the members of the group to generate an output for the computation, wherein the output is generated during execution of the computer program; and reusing, by the computer processor, the output for the computation involving the centroid vector for another computation involving another member of the group.

Application number: 17/614,787

Abstract:
An exemplary transparent tandem organic solar cell comprises a transparent substrate; a first transparent electrode disposed on a surface of the transparent substrate; and a series of interconnecting organic active layers disposed on a surface of the first transparent electrode. The series of organic interconnecting active layers comprise at least a front sub-cell that blocks ultraviolet wavelengths from passing through the front sub-cell; and a back sub-cell that blocks infrared wavelengths from passing through the back sub-cell. The solar cell further comprises a distributed Bragg reflector disposed on a surface of the back sub-cell, wherein the distributed Bragg reflector reflects unblocked infrared photons at an interface between the back sub-cell and the distributed Bragg reflector. Additionally, the series of interconnecting organic active layers are configured to allow wavelengths of visible light to pass through the transparent tandem organic solar cell, wherein the transparent tandem organic solar cell is fully transparent.

Application number: 17/536,355

Abstract:
A method of treatment includes modifying and/or killing cells by changing the cell membrane charging time to make the cells more susceptible to the influence of electric fields. The method may further include inserting one or more electrodes into tissue, acquiring a temperature of the tissue, delivering electrical energy to the tissue by electrical pulses, determining a rate of energy delivery of the electrical energy such that the temperature rises above a first critical temperature but remains below a second critical temperature, and delivering the electrical energy until a specific dose is achieved.
