A Simple Fabry-Perot-Based Germanium Bolometer for CO2 Monitoring: Simulation and Measurement
Abstract We report on the design of a simple germanium bolometer designed as a Fabry-Perot absorbing structure, which can be used for monitoring, e.g., CO2, where no additional filter is required. CO2 is absorbs IR radiation in a major band centered ...

Reinforcement learning for discounted values often loses the goal in the application to animal learning
Abstract The impulsive preference of an animal for an immediate reward implies that it might subjectively discount the value of potential future outcomes. A theoretical framework to maximize the discounted subjective value has been established in...

Applications of Tensegrity Structures in Civil Engineering
Abstract The objective of the present paper is to describe the applications of tensegrity structures in civil engineering (roofs, domes, stadiums, etc.). The term of tensegrity was introduced by Fuller in the middle 50th of XX century. There are...

Doping Level Dependence of Transport Properties in InAsSb Quantum Wells
Abstract We investigated the transport properties of the Al0.1In0.9Sb/InAs0.1Sb0.9 quantum wells (QWs). Intentional doping of donors to the QW is effective to decrease the sheet resistance and suppress its temperature dependence because the carrier...
