Background:
- 5G Advance (5GA) edge networks face challenges in low-latency, high-reliability data transmission.
- Untrusted edge networks are vulnerable to data tampering, discarding, and eavesdropping.
Purpose of the Study:
- To propose LERMS, a novel packet-level encoding transmission scheme for 5GA edge networks.
- To enhance data transmission resiliency against malicious attacks in untrusted edge environments.
Main Methods:
- LERMS utilizes 5GA Protocol Data Unit (PDU) coded Concurrent Multipath Transfer (CMT).
- Employs Lagrangian interpolation and Raptor's two-layer coding for redundancy.
- Incorporates queue-aware variable block length strategy, modeled via Markov chain and matrix optimization.
Main Results:
- LERMS demonstrates effective resiliency against data tampering, discarding, and eavesdropping.
- Achieves an optimal trade-off between transmission delay and reliability.
- Mitigates increased queuing delay through variable block length encoding.
Conclusions:
- LERMS provides a robust solution for secure and efficient data transmission in 5GA edge networks.
- The proposed scheme ensures high reliability and low latency in untrusted network conditions.

01:18Reducing Line Loss
173
In a three-phase circuit, line loss is an indicator of energy dissipated as heat due to the resistance of transmission lines. To address this, incorporating transformers into the system—a step-up transformer at the source and a step-down transformer at the load—is a strategic solution. Two three-phase transformers are introduced to improve this.
With a step-up transformer at the source, the voltage is increased, thereby reducing the current in the transmission lines since power loss...

Carrier-mediated transport is a pivotal process in drug absorption, particularly for lipid-insoluble drugs, and encompasses facilitated diffusion and active transport. Facilitated diffusion allows drugs to move along their concentration gradient without energy expenditure, while active transport utilizes ATP to drive drug movement against this gradient.
Active transport involves two types of membrane-spanning transporters: uptake and efflux. Uptake transporters are expressed in the small...

Aluminum has become the material of choice for overhead transmission lines, surpassing copper due to its abundance and cost-effectiveness. The most prevalent type is the aluminum conductor, steel-reinforced (ACSR), which combines aluminum strands around a steel core. Other variants include all-aluminum conductors (AAC), all-aluminum alloy conductors (AAAC), aluminum conductor alloy-reinforced (ACAR), and aluminum-clad steel conductors. Advanced designs, such as aluminum conductors with steel...

01:25Network Function of a Circuit
324
Frequency response analysis in electrical circuits provides vital insights into a circuit's behavior as the frequency of the input signal changes. The transfer function, a mathematical tool, is instrumental in understanding this behavior. It defines the relationship between phasor output and input and comes in four types: voltage gain, current gain, transfer impedance, and transfer admittance. The critical components of the transfer function are the poles and zeros.

01:11IP3/DAG Signaling Pathway
12.2K
Membrane lipids such as phosphatidylinositol (PI) are precursors for several membrane-bound and soluble second messengers. Specific kinases phosphorylate PI and produce phosphorylated inositol phospholipids. One such inositol phospholipids are the phosphatidylinositol-4,5 bisphosphate [PI(4,5)P2], present in the inner half of the lipid bilayer. Upon ligand binding, GPCR stimulates Gq proteins to turn on phospholipase Cꞵ. Activated phospholipase Cꞵ cleaves PI(4,5)P2 and...

Numerous practical applications within engineering disciplines, such as telecommunications, necessitate optimizing power delivery to a connected load. This pursuit, however, entails inherent internal losses, which can either equal or exceed the power supplied to the load. The Thevenin equivalent circuit is helpful in finding the maximum power a linear circuit can deliver to a load. It is assumed in this context that the load resistance can be adjusted.
