Low complexity Turbo synchronization without initial carrier synchronization [PDF]

open access: yesAdvances in Radio Science, 2010
Wireless data transmission results in frequency and phase offsets of the signal in the receiver. In addition the received symbols are corrupted by noise.

Global and Partial Phase Synchronizations in Arrays of Piecewise Linear Time-Delay Systems

open access: yes, 2012
In this paper, we report the identification of global and partial phase synchronizations in linear arrays of unidirectionally coupled piecewise linear time-delay systems with two different coupling configurations.

Noise-Induced Synchronization and Clustering in Ensembles of Uncoupled Limit-Cycle Oscillators [PDF]

open access: yes, 2007
We study synchronization properties of general uncoupled limit-cycle oscillators driven by common and independent Gaussian white noises. Using phase reduction and averaging methods, we analytically derive the stationary distribution of the phase ...

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Joint Narrowband RFI Suppression and Phase Synchronization Signal Retrieval for BiSAR via Robust Principal Component Analysis

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Due to the complex electromagnetic environment and the increased demand for frequency occupation, radio frequency interference (RFI) is becoming a significant issue for the bistatic synthetic aperture radar (BiSAR), especially in the synchronization ...

Stable frequency transfer for clock synchronization for telecom networks

open access: yesEURASIP Journal on Advances in Signal Processing, 2023
A stable and reliable clock synchronization system that transfers reference clocks to nodes is essential for telecom networks. Mainly, the clock synchronization of telecom networks is carried out through satellite links.

BMI‐1 modulation and trafficking during M phase in diffuse intrinsic pontine glioma

open access: yesFEBS Open Bio, EarlyView.
The schematic illustrates BMI‐1 phosphorylation during M phase, which triggers its translocation from the nucleus to the cytoplasm. In cycling cells, BMI‐1 functions within the PRC1 complex to mediate H2A K119 monoubiquitination. Following PTC596‐induced M phase arrest, phosphorylated BMI‐1 dissociates from PRC1 and is exported to the cytoplasm via its

Transitions to Measure Synchronization in Coupled Hamiltonian Systems

open access: yes, 2002
Transitions to measure synchronization in two coupled $\phi ^{4}$ lattices are investigated based on numerical simulations. The relationship between measure synchronization (MS), phase locking and system's total energy is studied both for periodic and ...
