Detection of a Spin Accumulation in Nondegenerate Semiconductors [PDF]
, 2007 Electrical detection of a spin accumulation in a nondegenerate semiconductor using a tunnel barrier and ferromagnetic contact is shown to be fundamentally affected by the energy barrier associated with the depletion region.

Quantum error-detection at low energies [PDF]
Journal of High Energy Physics, 2019 Abstract Motivated by the close relationship between quantum error-correction, topological order, the holographic AdS/CFT duality, and tensor networks, we initiate the study of approximate quantum error-detecting codes in matrix product states (MPS).

Adaptive Double-Threshold Cooperative Spectrum Sensing Algorithm Based on History Energy Detection
Wireless Communications and Mobile Computing, 2020 Spectrum sensing is one of the key technologies in the field of cognitive radio, which has been widely studied. Among all the sensing methods, energy detection is the most popular because of its simplicity and no requirement of any prior knowledge of the

Longitudinal energy waste detection with visualization [PDF]
Proceedings of the 4th ACM International Conference on Systems for Energy-Efficient Built Environments, 2017 Leaky windows and doors, open refrigerators, unattended appliances, left-on lights, and other sources subtly leak energy accounting for a large portion of waste. Formal energy audits are expensive and time consuming and do not capture many sources of leakage and waste.

Analytical Modeling of Wi-Fi and LTE-LAA Coexistence: Throughput and Impact of Energy Detection Threshold [PDF]
IEEE/ACM Transactions on Networking, 2018 With both small-cell LTE and Wi-Fi networks available as alternatives for deployment in unlicensed bands (notably 5 GHz), the investigation into their coexistence is a topic of active interest, primarily driven by industry groups.

Antimatter from supersymmetric dark matter [PDF]
, 2000 We propose low-energy antideuterons in cosmic rays as a new possible signature for indirect detection of supersymmetric dark matter. Since the energy spectrum of the antiproton secondary component is still spoilt by considerable theoretical ...

Spectrum sensing: Enhanced energy detection technique based on noise measurement [PDF]
Computing and Communication Workshop and Conference, 2018 Spectrum sensing enables cognitive radio systems to detect unused portions of the radio spectrum and then use them while avoiding interferences to the primary users. Energy detection is one of the most used techniques for spectrum sensing because it does

Enhanced Sensing and Sum-Rate Analysis in a Cognitive Radio-Based Internet of Things
Sensors, 2020 Spectrum sensing plays a vital role in cognitive radio networks (CRNs) for identifying the spectrum hole. However, an individual cognitive radio user in a CRN does not obtain sufficient sensing performance and sum rate of the primary and secondary links ...

Detecting ντ oscillations at PeV energies [PDF]
Astroparticle Physics, 1995 It is suggested that a large deep underocean neutrino detector, given the presence of significant numbers of neutrinos in the PeV range as predicted by various models of Active Galactic Nuclei, can make unique measurements of the properties of neutrinos.
