DC-LB-RSCA: a load-balanced framework for survivable routing of crosstalk-aware data center traffic in SDM-EONs

Discover Applied Sciences
The rapid expansion of cloud services and data center (DC) traffic demands an optical network infrastructure that is both elastic and resilient. Elastic Optical Networks (EONs) based on Space Division Multiplexing (SDM) and multi-core fibers (MCFs) offer

Quantum Saturation of the Electro‐Optic Effect

Advanced Materials, EarlyView.
At low temperatures, quantum fluctuations saturate the ferroelectric soft mode, suppressing thermal sensitivity in functional properties. By tuning the phase boundaries of ferroelectric materials to 0 K, large temperature insensitive electro‐optic effects are realized, establishing a pathway toward high‐efficiency optical modulation for quantum ...

A Kind of Joint Routing and Resource Allocation Scheme Based on Prioritized Memories-Deep Q Network for Cognitive Radio Ad Hoc Networks

Sensors, 2018
Cognitive Radio (CR) is a promising technology to overcome spectrum scarcity, which currently faces lots of unsolved problems. One of the critical challenges for setting up such systems is how to coordinate multiple protocol layers such as routing and ...

Valid inequalities for the routing and spectrum allocation problem in elastic optical networks [PDF]

, 2014
We deal with a natural integer-linear programming formulation of the routing and spectrum allocation (RSA) problem in elastic optical networks. We focus on strengthening the formulation with valid inequalities (cuts).

An Engineered Thio‐Amino Polymer Achieves Potent, Safe, and Broad Cell Type Delivery in the Lung Mapped by Spatial Transcriptomics

Advanced Materials, EarlyView.
Synthesis and screening of a polymer library produced a versatile and inhalable mRNA vehicle for the lungs (P81). Compared to a published LNP, P81 provides increased delivery efficacy, achieving widespread expression in broad cell types, with no toxicity.

A Cross‐Layer Spatial–Spectral Optimization Framework for Hybrid Routing and Load‐Balanced Channel Allocation in Intelligent Networks

Engineering Reports
Intelligent cross‐layer resource management mechanisms are required by the rapid development of 5G and new 6G networks, as they are heterogeneous in traffic requirements, ultra‐dense in deployment, and dynamic spectrum conditions. Traditional routing and

Joint rate allocation, routing and spectrum sharing for multi-hop Cognitive Radio Networks with imperfect spectrum sensing

, 2010
In this paper we study the joint rate allocation, routing and spectrum sharing policy for multi-hop Cognitive Radio Networks (CRNs). We formulate this cross layer optimization problem as a sequential decision process which aims to minimize the average ...

Hybrid Roll‐To‐Plate Printed CMOS Logic Circuits Via an Integrated Gravure‐Flexographic Printing Strategy

Advanced Materials Interfaces, EarlyView.
A layer‐specific hybrid gravure–flexographic printing strategy enables fully printed SWCNT thin‐film transistors and CMOS logic circuits on flexible substrates. Flexographic printing forms the thin gate and drain‐source electrodes with defined edges, whereas gravure printing forms the uniform dielectric, semiconductor, and doping layers. The integrated
