Sparse Blind Deconvolution with Nonconvex Optimization for Ultrasonic NDT Application

Sensors, 2020
In the field of ultrasonic nondestructive testing (NDT), robust and accurate detection of defects is a challenging task because of the attenuation and noising of the ultrasonic wave from the structure.

A consistency method of discharge detection results at solar‐blind ultraviolet based on a radiation transmission model

IET Science, Measurement & Technology, 2022
Solar‐blind ultraviolet (UV) discharge detection based on UV signals in the solar‐blind band from 240 to 280 nm is an effective non‐contact discharge detection method for electrical equipment, but there is still a problem that the detection results of ...

Fading performance evaluation of a semi-blind space-time equaliser for frequency selective MIMO systems [PDF]

, 2011
A semi-blind adaptive space–time equaliser (STE) has recently been proposed based on a concurrent gradient-Newton(GN) constant modulus algorithm (CMA) and soft decision-directed (SDD) scheme for dispersive multiple-input multiple-output (MIMO) systems ...

Low-complexity high-performance GFSK receiver with carrier frequency offset correction [PDF]

, 2004
This paper presents an implementation of a GFSK receiver based on matched filtering of a sequence of K successive bits. This enables improved detection and superior BER performance but requires 2K matched filters of considerable complexity.

Treatment with KCL‐286, a first‐in‐class retinoic acid receptor‐β (RARβ) agonist, ameliorates neuronal DNA damage and inflammation in a mouse model of Alzheimer's disease

FEBS Open Bio, EarlyView.
Repair of neuronal DNA damage in Alzheimer's disease by KCL‐286. (A) Amyloid‐β oligomers and plaques impair neuronal DNA repair pathways, leading to DNA double‐strand breaks and glial activation. (B) KCL‐286 activates RARβ/RXR signalling via retinoic acid response elements (RAREs), associated with increased BRCA1 expression, enhanced DNA repair and ...

Blind detection of cyclostationary signals based on multi‐antenna beamforming technology

IET Communications, 2021
Cyclostationary feature detection is one of the widely used spectrum sensing techniques. Its greatest advantage is that it can effectively separate the signal from the noise under the condition of a low signal‐noise ratio (SNR).
