BEST FIT MODELS TEST FOR THE VIRTUAL CHANNEL IN DISTRIBUTED VIDEO CODING [PDF]

Journal of Engineering Science and Technology, 2011
Wyner-Ziv (WZ) video coding – a particular case of distributed video coding (DVC) – is a new video coding paradigm based on two major Information Theory results: the Slepian-Wolf and Wyner-Ziv theorems.

Flexible Selenium Nanowires with Tuneable Electronic Bandgaps

Advanced Materials, EarlyView.
Nanotubes serve as effective test tubes for selenium nanowires, as their diameter precisely controls the width of the nanowires and the Se─Se bonding, resulting in a variety of different structures. An electron beam can be used to modify the nanotubes, allowing real‐time observation of the nanowire extrusion process. Additionally, optically transparent

Training-free Guidance in Text-to-Video Generation via Multimodal Planning and Structured Noise Initialization [PDF]

arXiv
Recent advancements in text-to-video (T2V) diffusion models have significantly enhanced the visual quality of the generated videos. However, even recent T2V models find it challenging to follow text descriptions accurately, especially when the prompt requires accurate control of spatial layouts or object trajectories.

Thermally Activated Swelling and Wetting Transition of Frozen Polymer Brushes:a New Concept for Surface Functionalization

Advanced Materials, EarlyView.
A novel approach is introduced that leverages polymer phase transitions to modulate brush behavior. The oleophilic bottle brush system exhibits two distinct melting transitions—bulk and surface—enabling a two‐stage swelling and wetting transition.

MULDE: Multiscale Log-Density Estimation via Denoising Score Matching for Video Anomaly Detection [PDF]

arXiv
We propose a novel approach to video anomaly detection: we treat feature vectors extracted from videos as realizations of a random variable with a fixed distribution and model this distribution with a neural network. This lets us estimate the likelihood of test videos and detect video anomalies by thresholding the likelihood estimates.

3D Printing of Auxetic Self‐powered Mechanoluminescent Photonic Skins for Underwater Communication and Safety Monitoring

Advanced Materials, EarlyView.
A 3D‐printed self‐powered auxetic mechanoluminescent photonic skin for underwater communication and safety monitoring is introduced. Its auxetic structures, with a negative Poisson's ratio, ensure exceptional conformability to curved surfaces, enhancing adaptability to dynamic underwater environments.
