Multi-species Conserved Sequences02:51

Multi-species Conserved Sequences

4.7K
Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale  studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved...

Locus of Control01:26

Locus of Control

214
Locus of control describes how individuals perceive the causes of events in their lives, influencing motivation and well-being. Introduced by Julian Rotter in 1954, it is categorized into internal and external locus of control.Internal Locus of ControlIndividuals with an internal locus of control believe their actions determine outcomes, fostering responsibility, self-efficacy, and motivation. For example, an employee may attribute career success to hard work. Research links this mindset to...

Root-Locus Method01:19

Root-Locus Method

495
A cruise control system in a car is designed to maintain a specified speed automatically by adjusting the gas pedal. The system continuously measures the vehicle's speed and makes fine adjustments to the pedal to achieve this goal. The root locus method is particularly useful for understanding how the cruise control system's behavior changes under varying conditions, such as when the car goes uphill, downhill, or faces strong wind resistance.
This system can be represented by a block...

Construction of Root Locus01:15

Construction of Root Locus

409
The construction of a root locus involves several key steps to analyze and visualize the behavior of a system's poles with varying gain. The number of branches in the root locus equals the number of closed-loop poles and is symmetrical about the real axis.
For positive gain values, the root locus exists on the real axis to the left of an odd number of finite open-loop poles or zeros. The root locus starts at the open-loop poles and traces the paths of the closed-loop poles as the gain...

Properties of the Root Locus

298
The root locus method is an invaluable tool for analyzing higher-order systems without needing to factor the denominator of the transfer function. A pole of the system is identified when the characteristic polynomial in the transfer function's denominator equals zero.
To determine if a point lies on the root locus, the criterion involves the sum of angles contributed by all poles and zeros to that point. Specifically, this sum must be an odd multiple of 180 degrees. The gain at any point on...

Rotter's Locus of Control01:14

Rotter's Locus of Control

924
Julian Rotter introduced the concept of locus of control, a cognitive factor that significantly influences personality development and learning. Locus of control refers to an individual's beliefs about the extent of control they have over events in their lives. According to Rotter, this belief system can be categorized into two types: internal and external locus of control.
Individuals with an internal locus of control believe that their personal efforts and decisions directly affect their...

Area of Science:

  • Microbiology
  • Genetics
  • Epidemiology

Background:

  • Rodentibacter pneumotropicus is a bacterium commonly associated with rodents.
  • Accurate identification and typing methods are crucial for understanding its epidemiology.

Purpose of the Study:

  • To develop a definitive typing system for Rodentibacter pneumotropicus.
  • To establish a multi-locus sequence typing (MLST) scheme for strain differentiation.

Main Methods:

  • Developed an MLST scheme using seven house-keeping genes (atpG, frdB, gdh, pgi, pmi, recA, zwf).
  • Sequenced internal fragments (399-839 bp) of these genes for 79 R. pneumotropicus strains.
  • Utilized whole genomic sequences for 14 strains, including 10 newly sequenced.

Main Results:

  • Identified 5 to 7 alleles per locus, resulting in 20 distinct allelic profiles or sequence types (STs) among the 79 strains.
  • Observed stable STs, suggesting long-term circulation within and potential transfer between rodent colonies.
  • The MLST scheme demonstrated high resolution for differentiating R. pneumotropicus strains.

Conclusions:

  • The developed MLST scheme is a valuable tool for studying the population structure and epidemiology of R. pneumotropicus.
  • Future development may involve incorporating additional genes and strains, alongside whole genome sequencing.
