Abstract: A focused treatment tip (FTT) for controlling the evaporation rate and providing targeted delivery of low temperature liquified gases for contact with living tissue includes a contoured body. When filled with liquified gas, the device insulates the gas from waste heat sources, such as the surrounding environment. The device can control the evaporation rate of the liquified gas at the treatment site. The controlled evaporation rate affects the rate of heat transfer from the treated tissue allowing for controlled exposure times and desired outcomes. The device can be used with various application tips to further define the target tissue area to be treated while minimizing collateral damage to surrounding tissue and isolating the gas within the contoured body and focusing heat transfer to the desired treatment area. The device may use transparent materials that make the treatment visible to the operator while the liquified gas is evaporating.

Abstract: A III-nitride optoelectronic device includes at least one n-type layer, an active region grown on or above the n-type layer, at least one p-type layer grown on or above the active region, and a tunnel junction grown on or above the p-type layer. A conductive oxide may be wafer bonded on or above the tunnel junction, wherein the conductive oxide comprises a transparent conductor and may contain light extraction features on its non-bonded face. The tunnel junction also enables monolithic incorporation of electrically-injected and optically-pumped III-nitride layers, wherein the optically-pumped III-nitride layers comprise high-indium-content III-nitride layers formed as quantum wells (QWs) that are grown on or above the tunnel junction. The optically-pumped high-indium-content III-nitride layers emit light at a longer wavelength than the electrically-injected III-nitride layers.

Abstract: A system for managing prescriptions via a blockchain is provided. The system records in the blockchain a prescription transaction that identifies a prescription that has been written for a patient. The system then records in the blockchain a submission selection transaction with code for controlling selection of a pharmacy to dispense the prescription. For pharmacies that provide a submission for dispensing the prescription, the system records in the blockchain a submission transaction with submission information relating to dispensing of the prescription by the pharmacy. When a pharmacy is selected to dispense the prescription, the system records in the blockchain a selected submission transaction indicating the pharmacy selected to dispense the prescription. When the prescription is dispensed, the system records in the blockchain a dispense transaction indicating that the selected pharmacy has dispensed the prescription.

Abstract: A channel-less microfluidic pump includes a cartridge including a substrate and an actuatable film layer disposed on the substrate, and a manifold having at least three actuatable void volumes separated by a plurality of wall sections and an actuatable flexible layer disposed on the manifold interfacing the actuatable film layer. In operation, the pump can be in an unactuated state wherein the actuatable film layer is disposed against the surface of the substrate or an actuated state wherein at least a portion of the flexible layer and a corresponding portion of the actuatable film layer are deflected into a corresponding void volume thus forming a fluidic volume between the deflected portion of the actuatable film layer and the surface of the substrate. In the actuated state, there is a fluidic gap between immediately adjacent void volumes formed by a thinned region of the flexible layer at a point of contact with a top surface of a wall section.

Abstract: The disclosure provides a method for treating a subject afflicted with a tumor comprising administering to the subject a therapeutically effective amount of an anti-PD-1 antibody or antigen-binding portion thereof or an anti-PD-L1 antibody or anti-gen-binding portion thereof, wherein the subject is identified as having a high inflammatory gene signature score and a tumor that has a high tumor mutation burden (TMB) status. In some embodiments, the high inflammatory gene signature score is determined by measuring the expression of a panel of inflammatory genes in a tumor sample obtained from the subject, wherein the inflammatory gene panel comprises CD274 (PD-L1), CD8A, LAG3, and STAT1.

Abstract: A hybrid growth method for III-nitride tunnel junction devices uses metal-organic chemical vapor deposition (MOCVD) to grow one or more light-emitting or light-absorbing structures and ammonia-assisted or plasma-assisted molecular beam epitaxy (MBE) to grow one or more tunnel junctions. Unlike p-type gallium nitride (p-GaN) grown by MOCVD, p-GaN grown by MBE is conductive as grown, which allows for its use in a tunnel junction. Moreover, the doping limits of MBE materials are higher than MOCVD materials. The tunnel junctions can be used to incorporate multiple active regions into a single device. In addition, n-type GaN (n-GaN) can be used as a current spreading layer on both sides of the device, eliminating the need for a transparent conductive oxide (TCO) layer or a silver (Au) mirror.
