Multi-feature radar signal modulation recognition based on improved PSO algorithm

The Journal of Engineering, 2019
In order to solve the problem that radar emitter signal modulation recognition under low signal-to-noise ratio (SNR) has difficulty in selecting the parameters of the classifier and the problem of low recognition rate caused by the improper selection of ...

Performance of the LHCb vertex locator [PDF]

, 2014
The Vertex Locator (VELO) is a silicon microstrip detector that surrounds the proton-proton interaction region in the LHCb experiment. The performance of the detector during the first years of its physics operation is reviewed.

Depletion of signal recognition particle 72kDa increases radiosensitivity [PDF]

Cancer Biology & Therapy, 2017
The identification of genetic determinants that underpin tumor radioresistance can help the development of targeted radiosensitizers or aid personalization of radiotherapy treatment. Here we identify signal recognition particle 72kDa (SRP72) as a novel gene involved in radioresistance.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

A ribosome-associated chaperone enables substrate triage in a cotranslational protein targeting complex

Nature Communications, 2020
Biochemistry combined with biophysical measurements and mathematical modeling offer insight into the mechanism by which the cotranslational chaperone, nascent polypeptide-associated complex (NAC), modulates substrate selection by signal recognition ...

A fast algorithm for vision-based hand gesture recognition for robot control [PDF]

, 2006
We propose a fast algorithm for automatically recognizing a limited set of gestures from hand images for a robot control application. Hand gesture recognition is a challenging problem in its general form.

Functional Characterization of Recombinant Chloroplast Signal Recognition Particle [PDF]

Journal of Biological Chemistry, 2001
The signal recognition particle (SRP) is a ubiquitous system for the targeting of membrane and secreted proteins. The chloroplast SRP (cpSRP) is unique among SRPs in that it possesses no RNA and is functional in post-translational as well as co-translational targeting.

Cell wall target fragment discovery using a low‐cost, minimal fragment library

FEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Immune-mediated Necrotizing Myopathy With Increased Creatine Phosphokinase and Positive Signal Recognition Particle: A Case Report

Caspian Journal of Neurological Sciences, 2022
Background: Knowledge about Immune-Mediated Necrotizing Myopathy (IMNM) has received significantly attention in recent years. In this study, we report a rare case of IMNM with increased Creatine Phosphokinase (CPK) and positive Signal Recognition ...
