Germanium‐Based Mid‐Infrared Integrated Photonics
Laser &Photonics Reviews, EarlyView.The mid‐infrared (mid‐IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Photonics integration in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological ...

Performance Analysis of a Novel Hybrid S-ALOHA/TDMA Protocol for Beta Distributed Massive MTC Access
Sensors, 2017 Simultaneous random access of massive machine type communications (MTC) devices are expected to cause congestion in the radio access network. Not only the performance of MTC, but the coexisting human to human (H2H) communications would also degrade ...

Unnatural Causes: Cryptocurrencies, Carbon Credits, and the rise of Neoliberalism from Below
Economic Anthropology, EarlyView.ABSTRACT Klima is a carbon‐backed cryptocurrency running as a decentralized autonomous organization (DAO). In 2021, it had accumulated 9 million metric tons of digital carbon credits and reached a market value of more than US$1 billion. In 2023, its treasury stored twice as many carbon credits, but its spot price was a tiny fraction compared to 2021 ...

Large-Scale NOMA: Promises for Massive Machine-Type Communication
CoRR, 2019 We investigate on large-scale deployment of non-orthogonal multiple access (NOMA) for improved spectral and power efficiency in cellular networks to provide massive wireless connectivity (e.g. for machine-type communication [mMTC]). First, we describe the basics of single-antenna NOMA technology and its extension to co-located multiple-antenna NOMA as ...
