HOS-based direction of arrival estimation
Electronics Letters, 1994 A new technique for estimating the direction of arrival of multiple non-Gaussian signals using higher order statistics is reported. A set of new algorithms based on a new class of performance criteria related to the bispectral power of the array data is presented.

Multiple Parameter Estimation With Quantized Channel Output
, 2010 We present a general problem formulation for optimal parameter estimation based on quantized observations, with application to antenna array communication and processing (channel estimation, time-of-arrival (TOA) and direction-of-arrival (DOA) estimation)

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Two Dimensional Direction-of-Arrival Estimation Using Compressive Measurements
IEEE Access, 2019 Compressive sensing can effectively reduce the dimension of a signal vector and has been widely used in many areas. Direction-of-arrival (DOA) estimation using compressive measurements has gained considerable attention due to the reduction in system ...

Structural biology of ferritin nanocages
FEBS 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 ...

Modelling Aspects of Planar Multi-Mode Antennas for Direction-of-Arrival Estimation [PDF]
, 2019 Multi-mode antennas are an alternative to classical antenna arrays, and hence a promising emerging sensor technology for a vast variety of applications in the areas of array signal processing and digital communications. An unsolved problem is to describe

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS 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+.

An enhanced expanding and shift sparse array based on the coprime array and nested array
IET Radar, Sonar & NavigationIn recent years, sparse arrays based on the fourth‐order difference coarray (FODCA) have received increased research attention due to their small number of array elements and large consecutive virtual arrays.
