Two-Dimensional Microscopy in Microbiology01:29

Two-Dimensional Microscopy in Microbiology

Two-dimensional (2D) microscopy encompasses a range of optical techniques that capture images within a single focal plane, offering detailed representations of microscopic structures. These techniques are essential in biological and medical research, enabling the visualization of cellular and subcellular structures with different levels of contrast and specificity.There are several major types of 2D microscopy, each with strengths and applications.Bright-Field MicroscopyBright-field microscopy...
Two-Dimensional (2D) NMR: Overview01:12

Two-Dimensional (2D) NMR: Overview

The 1D NMR spectrum of large and complex molecules like natural products has complicated splitting patterns and overlapping signals, which can be easily interpreted using 2-dimensional (2D) NMR. Unlike 1D NMR, 2D NMR has two frequency axes that provide the coupling information between the nucleus A and nucleus B in a molecule. The process from which 2D spectra are obtained has four steps.
The first step is the preparation period, during which nucleus A is excited with a radiofrequency pulse.
Determining the Plane of Cell Division02:13

Determining the Plane of Cell Division

Positioning the cell division plane is a critical step during development and cell differentiation, particularly during mitosis when the plane is essential for determining the size of the two daughter cells. The cell division plane is perpendicular to the plane of chromosome segregation, but different types of organisms have different cell division mechanisms to suit their morphology and function.

Time-Series Graph00:54

Time-Series Graph

A time-series graph is a line graph with repeated measurements taken at successive intervals of time. It is also called a time series chart. To construct a time-series graph, one must look at both pieces of a paired data set. The horizontal axis is used to plot the time increments, and the vertical axis is used to plot the values of the variable that one is measuring. By using the axes in this way, each point on the graph will correspond to time and a measured quantity. The points on the graph...
Relative Velocity in Two Dimensions01:11

Relative Velocity in Two Dimensions

Relative velocity is the velocity of an object as observed from a particular reference frame, or the velocity of one reference frame with respect to another reference frame. The concept of relative velocity can be used to describe motion in two dimensions. Consider a particle P and two reference frames S and S′. The position of the origin of S′ as measured in S is , the position of P as measured in S′ is , and the position of P as measured in S is , which can be evaluated by utilizing vector...

Area of Science:

  • Mathematical Biology
  • Theoretical Biology
  • Chronobiology

Background:

  • Traditional physical time representations are inadequate for capturing complex biological phenomena.
  • Biological rhythms (circadian, metabolic, heart beating, respiration) lack counterparts in standard physical clock formalizations.
  • Existing mathematical models of time do not fully encompass the autonomous nature of biological rhythms.

Purpose of the Study:

  • To propose an abstract mathematical framework for describing biological time.
  • To develop a novel representation for biological rhythms that accommodates their autonomous characteristics.
  • To explore potential applications in understanding biological variability and pathology.

Main Methods:

  • Development of a functional representation of biological time using a 2-dimensional manifold.
  • Utilizing a 3-dimensional embedding space to incorporate an additional 'representation time' dimension.
  • Visualizing biological rhythms, specifically heartbeats, within the proposed mathematical framework.

Main Results:

  • A 2D manifold effectively accommodates autonomous biological rhythms, offering a new perspective on biological time.
  • The mathematical framework provides a visual representation of rhythms, exemplified by heartbeats.
  • The inclusion of an extra dimension in the embedding space offers cognitive significance for 'representation time'.

Conclusions:

  • A 2D manifold representation offers a more suitable mathematical frame for biological time than linear physical time.
  • This approach can provide insights into interspecific differences and intraspecific pathologies through rhythm analysis.
  • The proposed framework has potential applications in advancing the understanding of biological systems and their temporal dynamics.
