Joint received signal strength, angle-of-arrival, and time-of-flight positioning [PDF]

open access: yes, 2019
This paper presents a software positioning framework that is able to jointly use measured values of three parameters: the received signal strength, the angle-of-arrival, and the time-of-flight of the wireless signals.

Optimal Precoders for Tracking the AoD and AoA of a mm-Wave Path [PDF]

open access: yes, 2018
In millimeter-wave channels, most of the received energy is carried by a few paths. Traditional precoders sweep the angle-of-departure (AoD) and angle-of-arrival (AoA) space with directional precoders to identify directions with largest power.

Radio Interferometric Angle of Arrival Estimation [PDF]

open access: yes, 2010
Several localization algorithms exist for wireless sensor networks that use angle of arrival measurements to estimate node position. However, there are limited options for actually obtaining the angle of arrival using resource-constrained devices. In this paper, we describe a radio interferometric technique for determining bearings from an anchor node ...

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Cooperative and Distributed Localization for Wireless Sensor Networks in Multipath Environments

open access: yes, 2011
We consider the problem of sensor localization in a wireless network in a multipath environment, where time and angle of arrival information are available at each sensor.

A Simple Photonic System for DFS and AOA Simultaneous Measurement

open access: yesPhotonics, 2022
A simple photonics-based dual-channel system is proposed to simultaneously measure the Doppler frequency shift (DFS) and angle of arrival (AOA) of microwave signals.

Angles of arrival of indoor multipath

open access: yesElectronics Letters, 1992
Some preliminary results of the angles of arrival of multipath components in indoor radio channel measurements are reported. The results show that strong multipath components arrive at the receiver in various directions.

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.
