Protein Networks02:26

Protein Networks

4.7K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Zones of Protection01:16

Zones of Protection

951
In power systems, the entire setup is divided into protective zones to isolate faults and protect the rest of the network. These zones include generators, transformers, buses, transmission lines, distribution lines, and motors. Each zone can be visualized as a separate room in a house, with each room protected by its own circuit breaker.
Protective zones are defined by closed dashed lines, containing one or more components. A key characteristic of these zones is the strategic placement of...

Defense Mechanism Against Infection01:26

Defense Mechanism Against Infection

11.6K
Natural flora, body system defenses, and inflammation are natural barriers of the body against infectious agents regardless of previous exposure. Normal floras of the human body refer to the microbial population that colonizes the skin and mucous membranes.
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...

Collisions in Multiple Dimensions: Introduction

7.5K
It is far more common for collisions to occur in two dimensions; that is, the initial velocity vectors are neither parallel nor antiparallel to each other. Let's see what complications arise from this. The first idea is that momentum is a vector. Like all vectors, it can be expressed as a sum of perpendicular components (usually, though not always, an x-component and a y-component, and a z-component if necessary). Thus, when the statement of conservation of momentum is written for a...

Defenses Against Pathogens and Herbivores

30.1K
Plants present a rich source of nutrients for many organisms, making it a target for herbivores and infectious agents. Plants, though lacking a proper immune system, have developed an array of constitutive and inducible defenses to fend off these attacks.

Radial System Protection01:23

Radial System Protection

486
Radial systems employ time-delay overcurrent relays to reduce load interruptions. When a fault occurs, the nearest breaker opens first, while upstream breakers remain closed due to longer delay settings. This approach ensures minimal disruption to the rest of the system.
In a radial system with a fault downstream of the third breaker, ideally, only the third breaker will open, isolating the fault and interrupting the load connected beyond it. The second breaker has a longer delay setting,...

Area of Science:

  • Network science
  • Complex systems
  • Cybersecurity

Background:

  • Network robustness is crucial for system reliability, but defenses against attacks, especially in networked engineering systems with detection, are understudied.

  • To propose and evaluate a sequential defense mechanism for complex networks to infer attacks and assess vulnerabilities.
  • To enhance network robustness by enabling timely attack identification before network disruption.

Main Methods:

  • A sequential defense mechanism is proposed, where a data fusion center infers attacks based on binary status reports from network nodes.
  • Network robustness is evaluated using a parametric plug-in model under random and intentional attack schemes.
  • The mechanism's effectiveness is validated on canonical complex network models and real-world network topologies.

Main Results:

  • The sequential defense mechanism significantly improves network robustness against attacks.
  • The proposed mechanism effectively mitigates network disruption by utilizing limited attack status information from a subset of nodes.
  • Performance evaluation demonstrates the mechanism's reliability and effectiveness.

Conclusions:

  • The sequential defense mechanism offers a viable strategy to bolster network resilience in the face of cyber threats.
  • Implementing such mechanisms is essential for maintaining the functionality of critical networked systems.
  • Further research can explore variations and optimizations of this defense approach for diverse network architectures.
