Electromechanical Imaging of Biological Systems with Sub-10 nm Resolution [PDF]

, 2005
Electromechanical imaging of tooth dentin and enamel has been performed with sub-10 nm resolution using piezoresponse force microscopy. Characteristic piezoelectric domain size and local protein fiber ordering in dentin have been determined. The shape of a single collagen fibril in enamel is visualized in real space and local hysteresis loops are ...

Paint4Poem: A Dataset for Artistic Visualization of Classical Chinese Poems [PDF]

arXiv, 2021
In this work we propose a new task: artistic visualization of classical Chinese poems, where the goal is to generatepaintings of a certain artistic style for classical Chinese poems. For this purpose, we construct a new dataset called Paint4Poem. Thefirst part of Paint4Poem consists of 301 high-quality poem-painting pairs collected manually from an ...

Intelli-Paint: Towards Developing Human-like Painting Agents [PDF]

arXiv, 2021
The generation of well-designed artwork is often quite time-consuming and assumes a high degree of proficiency on part of the human painter. In order to facilitate the human painting process, substantial research efforts have been made on teaching machines how to "paint like a human", and then using the trained agent as a painting assistant tool for ...

Simultaneous whole‐brain and cervical spine imaging at 7 T using a neurovascular head and neck coil with 8‐channel transceiver array and 56‐channel receiver array

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose To develop a 7T neurovascular head and neck (NVHN) coil with an extended longitudinal coverage of the brain and cervical spine, with eight transceiver (TxRx) channels and 56 receive (Rx) channels for dynamic parallel‐transmit (pTx) applications. Methods A dual‐row transceiver array with six elements in the upper row and two elements in

A Machine Learning Approach to Quantitative Analysis of Enamel Microstructure from Scanning Electron Microscopy Images

Small Structures, EarlyView.
A machine learning segmentation method is applied to electron microscope images of tooth enamel to enable quantitative analysis of the microstructure. A pretrained convolutional neural network is used to expand the input training image dataset to train a random forest classifier for segmentation.
