Spread Spectrum Magnetic Resonance Imaging [PDF]
IEEE Transactions on Medical Imaging, 2012 We propose a novel compressed sensing technique to accelerate the magnetic resonance imaging (MRI) acquisition process. The method, coined spread spectrum MRI or simply s2MRI, consists of pre-modulating the signal of interest by a linear chirp before random k-space under-sampling, and then reconstructing the signal with non-linear algorithms that ...

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Double CPSK Spread-spectrum Communication System
工程科学与技术, 2009 :To solve the limitation that conventional spread sptrum communication suffers from PN sources，a scheme of double Code Phase Shift Keying (CPSK) Spread Spectrum (SS) communication system was proposed,in which synchronization is achieved by ...

FEBS Letters, EarlyView.CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Spread Spectrum Storage with Mnemosyne [PDF]
, 2003 Redundancy in distributed systems is used to provide increased performance and reliability by techniques such as striping and mirroring [27.1], fast fail-over [27.2], and byzantine fault-tolerance [27.3]. These schemes are oriented toward collections of machines and devices which are fairly small (a few hundred at most) relative to modern wide-area ...

Spread-space spread-spectrum technique for secure multiplexing [PDF]
Optics Letters, 2007 A novel technique for multiplexing complex images is proposed in which each image may be demultiplexed only if a set of random encryption keys is known. The technique utilizes the ability of the double random phase encoding method to spread a signals' energy in both the space and the spatial frequency domains in a controlled manner.

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics
FEBS Letters, EarlyView.Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...

FEBS Letters, EarlyView.This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.
