Dual Physiological Barriers Bypassed by a Silk‐Based Supramolecular Protein Delivery Platform for Neuroinflammation Mitigation in Alzheimer's Disease

Advanced Science, EarlyView.
A supramolecular nanocomplex based on phenolic‐modified silk sericin is developed to deliver antioxidant enzymes across the blood–brain barrier and escape lysosomal degradation. This dual‐barrier‐crossing system reduces neuroinflammation and improves cognitive performance in Alzheimer's disease mouse model, offering a promising strategy for protein ...

CMOS‐Integrated Synaptic Photoreceptor Chip Inspired by Insect Visual Processing

Advanced Science, EarlyView.
CMOS‐integrated Si QDs/ReS2 synaptic photoreceptor array mimics the parallel processing and wavelength‐selective strategy of insect vision. By combining intrinsic ultraviolet‐violet sensitivity with synaptic plasticity, the chip enables frontend sensory redundancy reduction without external filters, offering a scalable pathway toward lowpower ...

Ultra‐Wide‐Field Noninvasive Imaging Through Scattering Media Via Physics‐Guided Deep Learning

Advanced Science, EarlyView.
We propose a physics‐guided adaptive dual‐domain learning method for ultra‐wide‐field noninvasive imaging through scattering media, namely UNI‐Net. Our method not only reduces the requirement for real experimental data by an order of magnitude but also enables clear imaging of complex scenes with an ultra‐large field of view, which is 164 times the OME

An information-hiding metric

Journal of Systems and Software, 1994
Abstract The most critical problem facing developers and maintainers of large software systems is overwhelming complexity. Abstraction, a powerful tool for dealing with complexity, limits details that must be considered to those that are most relevant.

Information hiding by coverings

Proceedings 2003 IEEE Information Theory Workshop (Cat. No.03EX674), 2004
We propose a formal model for embedding information in black and white images and prove the equivalence between the existence of embedding schemes and covering codes. An asymptotically tight bound on the performance of embedding schemes is given. We construct efficient embedding schemes via known coverings.

Hiding information in images

Proceedings 1998 International Conference on Image Processing. ICIP98 (Cat. No.98CB36269), 2002
We present a new method of embedding information within digital images, called spread spectrum image steganography (SSIS). Steganography, which means "covered writing" in Greek, is the science of communicating in a hidden manner. SSIS conceals a message of substantial length within digital imagery while maintaining the original image size and dynamic ...

Information hiding

Communications of the ACM, 2017
The practice of hiding ill-gotten data in digital objects is rising among cyber thieves. New initiatives serve to educate, train, and thwart these activities.

Hiding Information in Image Mosaics

The Computer Journal, 2003
Summary: Information hiding techniques allow a player to hide secret information in some innocent-looking document. In this paper we present a novel approach to information hiding. We investigate the possibility of embedding information using the intrinsic entropy of some classes of cover-documents. In particular we provide algorithms for embedding any

Hiding Information Hiding

2007
In this paper we introduce a new tool that hides whether or not an "encryption" algorithm actually performs encryption or not. We call this a computational questionable encryption scheme and show how it can be used to devise mobile agents that conceal whether they encrypt or delete data prior to data transmission.

Hiding Routing information

1996
This paper describes an architecture, Onion Routing, that limits a network's vulnerability to traffic analysis. The architecture provides anonymous socket connections by means of proxy servers. It provides real-time, bi-directional, anonymous communication for any protocol that can be adapted to use a proxy service.
