Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

5.8K
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

Defense Mechanism Against Infection01:26

Defense Mechanism Against Infection

6.6K
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...

Distributed Loads: Problem Solving

670
Beams are structural elements commonly employed in engineering applications requiring different load-carrying capacities. The first step in analyzing a beam under a distributed load is to simplify the problem by dividing the load into smaller regions, which allows one to consider each region separately and calculate the magnitude of the equivalent resultant load acting on each portion of the beam. The magnitude of the equivalent resultant load for each region can be determined by calculating...

Overview of Regeneration and Repair01:19

Overview of Regeneration and Repair

4.1K
Regeneration and repair processes are critical in healing damages caused by injury, disease, and aging. In regeneration, the damaged tissue is entirely replaced with new growth that restores the original architecture and function. In contrast, tissue repair usually results in a fixed tissue architecture involving scar formation. Scars generally do not reestablish tissue function and may also exhibit structural abnormalities at the injury site.

Long-patch Base Excision Repair

7.0K
Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:

Elastic Collisions: Case Study01:15

Elastic Collisions: Case Study

14.2K
Elastic collision of a system demands conservation of both momentum and kinetic energy. To solve problems involving one-dimensional elastic collisions between two objects, the equations for conservation of momentum and conservation of internal kinetic energy can be used. For the two objects, the sum of momentum before the collision equals the total momentum after the collision. An elastic collision conserves internal kinetic energy, and so the sum of kinetic energies before the collision equals...

Area of Science:

  • Computer Science
  • Networking
  • Cybersecurity

Background:

  • Wireless Sensor Networks (WSNs) are crucial for data collection in diverse IoT applications.
  • WSNs deployed in remote areas are vulnerable to jamming attacks, compromising data integrity and network operation.
  • Effective countermeasures are needed to ensure WSN reliability against malicious interference.

  • To propose a novel clustering-based self-healing strategy, Fairness Cooperation with Power Allocation (FCPA), to overcome jamming attacks in WSNs.
  • To enhance data transmission reliability and extend network lifetime despite jamming threats.
  • To evaluate the performance of FCPA against existing strategies under various jamming scenarios.

Main Methods:

  • Developed FCPA, a strategy that clusters the network, designates cluster heads, identifies jam-resistant routes, and optimizes transmission power.
  • Implemented a weighted relay approach to extend the operational lifetime of subnetworks.
  • Conducted experiments with 64 static WSN nodes and seven jammer locations, comparing FCPA with benchmarks.

Main Results:

  • FCPA significantly outperformed benchmark strategies, transmitting over 50% more information.
  • FCPA achieved an average of 967,961 kb of transmitted data and maintained 63% residual energy, demonstrating high energy efficiency.
