Surface Improvement of InAlAs/InGaAs InP-Based HEMT Through Treatments of UV/Ozone and TMAH
IEEE Journal of the Electron Devices Society, 2020 In this paper, we introduce novel surface treatments of UV/Ozone and TMAH to solve the surface problem of gate recess of InAlAs/InGaAs InP-based HEMTs. The problem of nonstoichiometric surface of InP etch stopper layer was found to be the result of donor-

Non-Invasive Determination of the Mass Flow Rate for Particulate Solids Using Microwaves
Sensors, 2023 This paper presents a novel technique for the mass flow rate determination of particulate solids called the “Sliding Mass Technique”. The mass flow rate is a measure of the mass of a substance that passes through a given cross-sectional area per unit ...

High-Frequency Trading on Decentralized On-Chain Exchanges [PDF]
IEEE Symposium on Security and Privacy, 2020 Decentralized exchanges (DEXs) allow parties to participate in financial markets while retaining full custody of their funds. However, the transparency of blockchain-based DEX in combination with the latency for transactions to be processed, makes market-

IEEE Access, 2021 The adoption of metal additive manufacturing into the production of passive microwave components is still in its relative infancy. However, it is of increasing interest due to the offer of geometrical design freedom and significant weight reduction.

SSRN Electronic Journal, 2019 This paper studies the behaviour of Bitcoin returns at different sample frequencies. We consider high frequency returns starting from tick-by-tick price changes traded at the Bitstamp and Coinbase exchanges. We find evidence of a smooth intra-daily seasonality pattern, and an abnormal trade- and volatility intensity at Thursdays and Fridays. We find no

Current Opinion in Anaesthesiology, 1988 The need to maintain adequate gas exchange in patients with respiratory insufficiency led already in the early beginning of the 20th century to the development of certain methods which can be apostrophized as the basis of the today techniques of the so called “High Frequency Ventilation” (HFV).

A Wide Frequency Scanning Printed Bruce Array Antenna with Bowtie and Semi-Circular Elements
Sensors, 2020 A printed edge-fed counterpart of the wire Bruce array antenna, for frequency scanning applications, is presented in this paper. The unit-cell of the proposed antenna consists of bowtie and semi-circular elements to achieve wide bandwidth from below 22 ...

High frequency off-target mutagenesis induced by CRISPR-Cas nucleases in human cells
Nature Biotechnology, 2013 Clustered, regularly interspaced, short palindromic repeat (CRISPR) RNA-guided nucleases (RGNs) have rapidly emerged as a facile and efficient platform for genome editing. Here, we use a human cell–based reporter assay to characterize off-target cleavage
