Attenuation coefficient as a quantitative parameter for analyzing cataracts with optical coherence tomography [PDF]

EPJ Web of Conferences, 2020
Crystalline lenses of mice were imaged in vivo with a custom-made swept-source optical coherence tomography system. The use of the attenuation coefficient as a quantitative parameter for investigating the lens opacities magnitude is proposed ...

Bias in magnitude-squared coherence estimation due to misalignment [PDF]

IEEE Transactions on Acoustics, Speech, and Signal Processing, 1980
This correspondence reviews the interpretation of the coherence function and provides a derivation for bias of coherence estimates due to misalignment. The derived expression is compared with previous results. It is shown that subsequent processing of underwater acoustic signals from a recent experiment corroborates the derived results for coherence ...

Robust estimation of the magnitude squared coherence based on kernel signal processing [PDF]

2017 51st Asilomar Conference on Signals, Systems, and Computers, 2017
A new outlier-robust approach to estimate the magnitude squared coherence of a random vector sequence, a common task required in a variety of estimation and detection problems, is proposed. The proposed estimator is based on Renyi's entropy, an information theoretic kernel-based measure that proves to be inversely proportional to the determinant of a ...

Plecstatin inhibits hepatocellular carcinoma tumorigenesis and invasion through cytolinker plectin

Molecular Oncology, EarlyView.
The ruthenium‐based metallodrug plecstatin exerts its anticancer effect in hepatocellular carcinoma (HCC) primarily through selective targeting of plectin. By disrupting plectin‐mediated cytoskeletal organization, plecstatin inhibits anchorage‐dependent growth, cell polarization, and tumor cell dissemination.

Control of spin coherence in semiconductor double quantum dots

, 2008
We propose a scheme to manipulate the spin coherence in vertically coupled GaAs double quantum dots. Up to {\em ten} orders of magnitude variation of the spin relaxation and {\em two} orders of magnitude variation of the spin dephasing can be achieved by

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Superconducting Cavity Qubit with Tens of Milliseconds Single-Photon Coherence Time

PRX Quantum, 2023
Storing quantum information for an extended period of time is essential for running quantum algorithms with low errors. Currently, superconducting quantum memories have coherence times of a few milliseconds, and surpassing this performance has remained ...

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

Molecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Complex-value coherence mapping reveals novel abnormal resting-state functional connectivity networks in task-specific focal hand dystonia

Frontiers in Neurology, 2013
Resting-state imaging designs are powerful in modeling functional networks in movement disorders because they eliminate task performance related confounds. However, the most common metric for quantifying functional connectivity, i.e.
