Sample Size Calculation01:19

Sample Size Calculation

6.4K
Knowledge of the sample size is the first requirement to conduct random sampling or an experiment. The sample size is the total number of units, observations, or groups (in some cases) used to get the data to estimate a population parameter. As the name suggests, the sample size is that of the sample drawn from the population and differs from the population size.
The sample size for the given experiment or sampling effort is fundamental to any study design. Sample size decides the number of...

Sexually Transmitted Infections01:26

Sexually Transmitted Infections

959
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Calculating the Equilibrium Constant02:46

Calculating the Equilibrium Constant

37.6K
The equilibrium constant for a reaction is calculated from the equilibrium concentrations (or pressures) of its reactants and products. If these concentrations are known, the calculation simply involves their substitution into the Kc expression.
For example, gaseous nitrogen dioxide forms dinitrogen tetroxide according to this equation:

Calculating Standard Free Energy Changes02:49

Calculating Standard Free Energy Changes

24.8K
The free energy change for a reaction that occurs under the standard conditions of 1 bar pressure and at 298 K is called the standard free energy change. Since free energy is a state function, its value depends only on the conditions of the initial and final states of the system. A convenient and common approach to the calculation of free energy changes for physical and chemical reactions is by use of widely available compilations of standard state thermodynamic data. One method involves the...

Calculating pH Changes in a Buffer Solution

57.8K
A buffer can prevent a sudden drop or increase in the pH of a solution after the addition of a strong acid or base up to its buffering capacity; however, such addition of a strong acid or base does result in the slight pH change of the solution. The small pH change can be calculated by determining the resulting change in the concentration of buffer components, i.e., a weak acid and its conjugate base or vice versa. The concentrations obtained using these stoichiometric calculations can be used...

Numerical Calculations

In engineering applications, the representation of the numerical value is critical. Presenting or reporting the answer is one of the essential parts of engineering practices. Numerical calculations are performed using handheld calculators or computers since numerically accurate answers are always preferred.
The solution to a problem is obtained using different methods. While manually solving algebraic symbols is one of the most common methods, the graphical method is often preferred. Computers...

Area of Science:

  • Epidemiology
  • Mathematical Biology
  • Infectious Disease Dynamics

Background:

  • The final size of an epidemic is crucial for understanding its impact.
  • Current models primarily use the Kermack-McKendrick framework.
  • Estimating final size for vector-transmitted infections remains a challenge.

Purpose of the Study:

  • To derive an explicit final size equation for vector-transmitted epidemic models.
  • To analyze the behavior of these models, particularly concerning epidemic thresholds and outcomes.
  • To extend epidemic modeling beyond classical SIR-type frameworks.

Main Methods:

  • Derivation of a novel explicit final size equation tailored for vector-transmitted diseases.
  • Numerical analysis of the derived equation to identify critical thresholds.
  • Investigation of model behavior under conditions including infection-induced mortality.

Main Results:

  • An explicit final size equation for vector-transmitted epidemics was successfully derived.
  • A threshold curve was identified, dividing the state space into distinct regions.
  • The presence of infection-induced death leads to bistable sub-regions, influencing epidemic outcomes.

Conclusions:

  • The developed model provides a new tool for estimating the final size of vector-borne epidemics.
  • Epidemic trajectories and final sizes are sensitive to initial conditions and model parameters, especially with mortality.
  • This work advances the understanding of complex epidemic dynamics in vector-transmitted diseases.
