Resource Aware Chaining and Adaptive Capacity Scaling for Service Function Chains in Distributed Cloud Network

IEEE Access, 2019
With the development of network technology such as software-defined network (SDN) and network function virtualization (NFV), Internet service providers (ISPs) are increasingly placing the virtual network function(VNF) instances at the network edge to ...

On Optimal Placement of Hybrid Service Function Chains (SFCs) of Virtual Machines and Containers in a Generic Edge-Cloud Continuum

CoRR, 2020
Traditionally, Network Function Virtualization (NFV) has been implemented to run on Virtual Machines (VMs) in form of Virtual Network Functions (VNFs). More recently, the so-called Serverless Computing has gained traction in cloud computing, offering Function-as-a-Service (FaaS) platforms that make use of containerization techniques to deploy services.

Reliable Service Function Chain Deployment Method Based on Deep Reinforcement Learning

Sensors, 2021
Network function virtualization (NFV) is a key technology to decouple hardware device and software function. Several virtual network functions (VNFs) combine into a function sequence in a certain order, that is defined as service function chain (SFC).

The Impact of ESG Rating Divergence on Excess Cash Holdings: Evidence From China A‐Share Listed Firms

Accounting &Finance, EarlyView.
ABSTRACT This paper investigates the relationship between ESG rating divergence and corporate excess cash holdings, employing a sample of Chinese A‐share listed companies from 2015 to 2021. Our findings reveal a significant positive relationship between ESG rating divergence and firms' excess cash holdings, a conclusion robust to various sensitivity ...

Anxiolytic and Memory Protective Effects of Withanolide D Isolated From Acnistus arborescens in Adult Zebrafish

Chemistry &Biodiversity, Volume 23, Issue 5, May 2026.
Withanolide D Exhibits Anxiolytic and Memory‐Protective Effects. ABSTRACT This study evaluated the anxiolytic and memory‐protective effects of withanolide D in adult zebrafish (Danio rerio). The compound was administered at doses of 4, 20, and 40 mg/kg and showed no signs of toxicity after 96 h of observation at any of the doses tested.

Cooperative Brønsted Acid and Photo‐Promoted Stereoselective Synthesis of Substituted Piperidones

Angewandte Chemie, Volume 137, Issue 51, December 15, 2025.
A Brønsted acid cooperates with a photoexcited carbonyl triplet to promote stereoselective C─C bond formation in disubstituted piperidones through a chromophore‐activator strategy. The Brønsted acid lowers the excitation energy gap, directs selective C─N bond cleavage over C─C fragmentation after H‐atom transfer, and enables enantioselective C─C bond ...
