Substrate Stress Relaxation Regulates Cell‐Mediated Assembly of Extracellular Matrix

Advanced Functional Materials, EarlyView.
Silicone‐based viscoelastic substrates with tunable stress relaxation reveal how matrix mechanics regulates cellular mechanosensing and cell‐mediated matrix remodelling in the stiff regime. High stress relaxation promotes assembly of fibronectin fibril‐like structures, increased nuclear localization of YAP and formation of β1 integrin‐enriched ...

Deep Interactive Region Segmentation and Captioning

, 2017
With recent innovations in dense image captioning, it is now possible to describe every object of the scene with a caption while objects are determined by bounding boxes.

Coagulative Granular Hydrogels with an Enzyme Catalyzed Fibrin Network for Endogenous Tissue Regeneration

Advanced Healthcare Materials, EarlyView.
Coagulative granular hydrogels are composed of packed thrombin‐functionalized microgels that catalyze the conversion of fibrinogen into a secondary fibrin network, filling the interstitial voids. This bio‐inspired approach stabilizes the biomaterial to match the robustness of bulk hydrogels without compromising injectability, mimicking the initial ...

Learning Compact Recurrent Neural Networks with Block-Term Tensor Decomposition

, 2018
Recurrent Neural Networks (RNNs) are powerful sequence modeling tools. However, when dealing with high dimensional inputs, the training of RNNs becomes computational expensive due to the large number of model parameters.

Fluid Forces Control Structural Remodeling of Blind‐Ended Lymphatic Microvessels

Advanced Healthcare Materials, EarlyView.
Using innovative microfluidic biofabrication with fluid mechanical insights, we recapitulated the blind‐ended microanatomy and physiological drainage properties of capillary lymphatics. Our results reveal the interrelationship between intra‐ and extraluminal regions of lymphatic vessels due to flow‐induced sprouting and morphological changes that ...

Generating Video Descriptions with Topic Guidance

, 2017
Generating video descriptions in natural language (a.k.a. video captioning) is a more challenging task than image captioning as the videos are intrinsically more complicated than images in two aspects.

Temporally Delayed Deployment of Photo‐Responsive Liquid Crystal Polymer Networks Toward Neural Interfaces

Advanced Healthcare Materials, EarlyView.
Deployable medical devices typically need external stimuli to trigger deployment. However, external stimuli are difficult to supply within tissues. Here, we describe a strategy to deploy small‐scale structures into soft tissues after insertion without the need for any stimulus. We demonstrate deployment within a tissue phantom.

Dense video captioning using unsupervised semantic information

Journal of Visual Communication and Image Representation
We introduce a method to learn unsupervised semantic visual information based on the premise that complex events can be decomposed into simpler events and that these simple events are shared across several complex events. We first employ a clustering method to group representations producing a visual codebook.

Spatio-temporal Video Re-localization by Warp LSTM

, 2019
The need for efficiently finding the video content a user wants is increasing because of the erupting of user-generated videos on the Web. Existing keyword-based or content-based video retrieval methods usually determine what occurs in a video but not ...
