Inverse‐Designed Superchiral Hot Spot in Dielectric Meta‐Cavity Toward Ultra‐Compact Enantioselective Detection

Advanced Optical Materials, EarlyView.
Linearly polarized incident light with normal incidence creates enhanced optical chirality hotspots on the metasurface. Several orders of magnitude optical chirality enhancement offers a promising route toward highly sensitive, compact chiral spectroscopy.

Code-expanded random access for machine-type communications [PDF]

2012 IEEE Globecom Workshops, 2012
The random access methods used for support of machine-type communications (MTC) in current cellular standards are derivatives of traditional framed slotted ALOHA and therefore do not support high user loads efficiently. Motivated by the random access method employed in LTE, we propose a novel approach that is able to sustain a wide random access load ...

Constraint Hubs Deployment for Efficient Machine-Type Communications [PDF]

IEEE Transactions on Wireless Communications, 2018
Massive Internet of Things (mIoT) is an important use case of 5G. The main challenge for mIoT is the huge amount of uplink traffic as it dramatically overloads the radio access network (RAN). To mitigate this shortcoming, a new RAN technology has been suggested, where small cells are used for interconnecting different devices to the network. The use of

Highly Repeatable Fibrous Crack‐Based Strain Sensor for Multichannel Continuous Tremor Monitoring in Parkinson's Disease and Essential Tremor

Advanced Science, EarlyView.
This study proposes a patch‐type tremor monitoring system based on high‐repeatable fibrous crack‐based strain sensor, capable of simultaneously measuring tremor in multiple locations such as thumb, index, and wrist. Through clinical trials involving Parkinson's disease and essential tremor patients, the proposed system demonstrates its potential as a ...

Random access for massive machine-type communications

CoRR, 2019
With an explosive development of the Internet-of-Things (IoT), the number of devices or machines (called users) connected to a base station is envisioned to reach tens of billions in the near future. In order to accommodate such a massive connectivity, random access schemes are deemed as an efficient method.
