A Novel Fast Reroute Mechanism Leveraging Selective RCE for High Availability Networks

IEEE Access
This paper proposes a novel FRR mechanism based on the selective Repair Computational Element (RCE) algorithm, which proactively calculates and distributes alternative FRR routing paths from a dedicated computation node.

Make Flows Great Again: A Hybrid Resilience Mechanism for OpenFlow Networks

Information, 2018
A top concern in Software-Defined Networking (SDN) is the management of network flows. The resource limitation in SDN devices, e.g., Ternary Content Addressable Memory (TCAM) size, and the signaling overhead between the control and data plane elements ...

Cross Kingdom Metabolic Engineering Paradigm Elevating Sustainable Protein Production

Advanced Science, EarlyView.
ABSTRACT Confronting the dual crisis of escalating global protein demand and unsustainable agriculture necessitates transformative solutions. Here, we pioneer evolutionary insights from maize nitrogen optimization via asparagine synthetase (ASNS) to rewire metabolism in Pichia pastoris.

Fast reroute paths algorithms

Telecommunication Systems, 2011
In order to keep services running despite link or node failure in MPLS networks, RSVP-TE fast reroute (FRR) schemes use precomputed backup label-switched path tunnels for local repair of LSP tunnels. In the event of failure, the redirection of traffic occurs onto backup LSP tunnels that have the same quality of service constraints as original paths ...

HMGCR‐Driven Cholesterol Metabolism Promotes Osteoarthritis Progression by Accelerating Synovial Fibroblast Senescence

Advanced Science, EarlyView.
In the pathological context of osteoarthritis (OA), the phosphorylation of AKT1 at Ser473 enhances its binding to Lys140 of Insig1, which facilitates the formation of AKT1–Insig1 complex. Subsequently, the activation of AKT1 promotes the phosphorylation of Insig1 at Ser189, potentially enhancing the dissociation of Insig1 from sterol regulatory element‑

AARS1‐Mediated H3K27 Lactylation Rewires Glycolysis to Sustain Aggressive and Recurrent Bladder Cancer

Advanced Science, EarlyView.
AARS1 drives PI3K–AKT–mTOR‐dependent glycolysis in bladder cancer, promoting lactate accumulation, increased lactylation, H3K27la enrichment at the HK2 promoter, and HK2 transcription. HK2 reinforces glycolysis, sustaining a metabolic–epigenetic program associated with tumor progression, recurrence, and metastasis.

Do More Open Economies Export Less Diversely in Brazilian Agribusiness?

Agribusiness, EarlyView.
ABSTRACT This paper asks whether municipalities with a larger export‐to‐revenue ratio display a more concentrated bundle of exported goods in Brazilian agribusiness. Recent advances in export imputation for Brazilian municipalities allow for an analysis of the concentration profile of each municipality and its association with export openness.

Segment routing for traffic engineering and effective recovery in low-earth orbit satellite constellations

Digital Communications and Networks
Low-Earth Orbit Satellite Constellations (LEO-SCs) provide global, high-speed, and low latency Internet access services, which bridges the digital divide in the remote areas. As inter-satellite links are not supported in initial deployment (i.e.
