Secret Key Generation Protocol for Optical OFDM Systems in Indoor VLC Networks

IEEE Photonics Journal, 2017
Although the visible light communication (VLC) channel has superior security than radio frequency channels, its broadcast character makes VLC links vulnerable to eavesdropping. Therefore, VLC networks need to support security to protect the user's

Encoding and Encryption via Dual‐Wavelength 3D Digital Light Processing

Angewandte Chemie International Edition, EarlyView.
Multi‐wavelength 3D DLP printing enables information encoding that can be encrypted on demand by applying orthogonal stimuli within a single material to trigger complementary responses. The 405 nm LED of the printer fabricates complex 3D geometries, while the 365 nm LED activates spiropyrans photochromism to program information into the structure ...

Group Secret Key Generation Using the Channel Phase: A Geometric Secrecy Approach

IEEE Access
Given the inherent constraint of low key generation rates in physical layer key generation schemes, mutual random phase injection is considered a viable solution for establishing common randomness quantities among legitimate nodes.

Synergistic Effect on Enhanced Oil Recovery in High Salinity Carbonate Reservoirs Using a Novel PEI‐Functionalized Carbon Nanotube Nanocomposite

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Enhancing oil recovery (EOR) in mature reservoirs is hindered by high interfacial tension (IFT) and oil‐wet rock formations, especially under harsh, high‐salinity conditions. This study aims to overcome these limitations by synthesizing a novel carbon nanotube nanocomposite covalently grafted with polyethylenimine and non‐covalently ...

A physical layer secret key consistency enhancement scheme using constellation decision information

Security and Safety
Secret key generation based on a wireless channel (WC-SKG) is a promising solution to address the security issues in wireless communication. However, the consistency of channel estimation between two legal communication nodes in WC-SKG is often poor due ...

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

The Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Drivers of tail evolution in squamates and their implications for the fossorial origin of snakes

The Anatomical Record, EarlyView.
Abstract The axial skeleton serves as the primary structural support in all vertebrates and is subdivided into five distinct regions: cervical, thoracic, lumbar, sacral, and caudal. Relaxation of constraints acting on the terminal end of the axial skeleton has led to remarkable variation in caudal vertebrae number across Squamata.

Modulation of Animal Gut Health by Milk Oligosaccharide

Animal Research and One Health, EarlyView.
This review summarizes the composition and structural characteristics of MOs across different mammalian species, and elucidates their roles and mechanisms in maintaining intestinal homeostasis by regulating gut microbiome and enhancing intestinal chemical, physical and immune barriers.

Integrating Remote Sensing, Archaeological Survey and Geophysical Prospections for the Enhancement of Roman Doclea, Montenegro

Archaeological Prospection, EarlyView.
ABSTRACT The Roman city of Doclea is a key archaeological site of Montenegro, valued for its impressive remains and its role in the nation's cultural identity within European and the Mediterranean history. Doclea was the second‐largest city in the province of Roman Dalmatia, a municipium created in the first century ad and named after the Illyrian ...
