Fully automated macular pathology detection in retina optical coherence tomography images using sparse coding and dictionary learning

Journal of Biomedical Optics, 2017
. We propose a framework for automated detection of dry age-related macular degeneration (AMD) and diabetic macular edema (DME) from retina optical coherence tomography (OCT) images, based on sparse coding and dictionary learning.

Water Permeates and Plasticizes Amorphous Carbon Dots: Unraveling the Inner Accessibility of the Nanoparticles by Glass Transition Studies

Advanced Materials, EarlyView.
The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.

Ideal code constrained supervised sparse coding

Journal of Computers, 2014
In this paper, we proposed a novel sparse codingalgorithm by using the class labels to constrain the learningof codebook and sparse code. We not only use the classlabel to train the classifier, but also use it to constructclass conditional codewords to make the sparse code asdiscriminative as possible.

Non‐Destructive Laser Nanopatterning of Superconducting Heterostructures in Topological Sn Thin Films

Advanced Materials, EarlyView.
We demonstrate successful fabrication of high‐quality α‐Sn/β‐Sn planar nanostructures with arbitrary shapes by focused laser irradiation on topological Dirac semimetal α‐Sn thin films. The irradiated regions transform into atomically smooth, superconducting β‐Sn with a critical temperature of 3.7 K.

Navigating Ternary Doping in Li‐ion Cathodes With Closed‐Loop Multi‐Objective Bayesian Optimization

Advanced Materials, EarlyView.
The search for advanced battery materials is pushing us into highly complex composition spaces. Here, a space with about 14 million unique combinations is efficiently explored using high‐throughput experimentation guided by Bayesian optimization with a deep kernel trained on both the Materials Project database and our data.

Cancer Cells Traverse Faster in Confined Space by Modifying Vimentin filaments With Nuclear Deformation and Promoting the Growth of Desired Tumor Spheroids

Advanced Materials Interfaces, EarlyView.
This study demonstrates how the Vimentin intermediate (VIM) filaments distribution/density regulates the attainment of different migration modes through cytoskeleton rearrangement and controls the nuclear morphology in migrating cells under physical confinement, which facilitates the faster traversing of those cells and the growth of post‐migration ...

Two‐Photon Polymerized Microvascular Environments for Multicellular Modeling of the Blood–Brain Tumor Barrier

Advanced Materials Technologies, EarlyView.
Modeling the blood–brain tumor barrier is challenging due to complex interactions between brain microvasculature and glioma cells. We present two‐photon polymerized 3D micro‐porous capillary‐like structures that support endothelial alignment, cytoskeletal organization, and pericyte‐endothelial‐glioma tri‐cultures.

Provably Accurate Double-Sparse Coding

, 2017
Sparse coding is a crucial subroutine in algorithms for various signal processing, deep learning, and other machine learning applications. The central goal is to learn an overcomplete dictionary that can sparsely represent a given input dataset. However, a key challenge is that storage, transmission, and processing of the learned dictionary can be ...
