BIBO stability of continuous and discrete -time systems01:24

BIBO stability of continuous and discrete -time systems

806
System stability is a fundamental concept in signal processing, often assessed using convolution. For a system to be considered bounded-input bounded-output (BIBO) stable, any bounded input signal must produce a bounded output signal. A bounded input signal is one where the modulus does not exceed a certain constant at any point in time.
To determine the BIBO stability, the convolution integral is utilized when a bounded continuous-time input is applied to a Linear Time-Invariant (LTI) system....

Classification of Systems-II

411
Continuous-time systems have continuous input and output signals, with time measured continuously. These systems are generally defined by differential or algebraic equations. For instance, in an RC circuit, the relationship between input and output voltage is expressed through a differential equation derived from Ohm's law and the capacitor relation,

Assembly of Signaling Complexes

6.3K
Multiprotein signaling complexes are formed in a dynamic process involving protein-protein interactions at the cytoplasmic domain of transmembrane receptors or enzymatic and non-enzymatic proteins associated with the receptor. These complexes ensure the activation and propagation of intracellular signals that regulate cell functions.

Calmodulin-dependent Signaling01:16

Calmodulin-dependent Signaling

5.8K
Calmodulin (CaM) is a calcium-binding protein in eukaryotes that controls various calcium-regulated cellular processes. It has four calcium-binding sites that bind calcium to form the calcium-calmodulin ( Ca2+-CaM) complex. GPCR stimulation increases the calcium levels in the cells that bind to CaM and induces a conformational change.
The Ca2+-CaM complex does not have enzymatic activity by itself. Instead, the complex binds downstream target proteins, including membrane proteins or enzymes,...

SAS, short for Statistical Analysis System, is a powerful data analysis, management, and visualization tool. Developed by the SAS Institute in the early 1970s, SAS has evolved into a comprehensive software suite used across various industries for statistical analysis, business intelligence, and predictive modeling.
Applications: SAS finds applications in numerous fields, including healthcare for clinical trial analysis, finance for risk assessment, marketing for customer data analysis, and...

Area of Science:

  • Systems biology
  • Computational biology
  • Bioinformatics

Background:

  • Biological models frequently incorporate parameters with inherent uncertainty or stochastic origins.
  • Current Systems Biology Markup Language (SBML) Level 3 Core lacks direct support for representing inexact numerical values.
  • The extensibility of SBML via packages offers a pathway to address limitations in the Core specification.

Purpose of the Study:

  • To introduce a mechanism for representing inexact and stochastic values within biological models.
  • To extend the Systems Biology Markup Language (SBML) Level 3 Core specification.
  • To enable the encoding of value distributions and uncertainty in computational models.

Main Methods:

  • Leveraging the SBML package mechanism for extending the Core specification.
  • Developing and integrating the SBML Distributions package.
  • Implementing syntactic constructs to represent probability distributions and uncertainty.

Main Results:

  • The SBML Distributions package successfully extends SBML Level 3.
  • Models can now explicitly encode information about the distribution and uncertainty of parameter values.
  • Facilitates more accurate representation of stochastic and uncertain biological systems.

Conclusions:

  • The SBML Distributions package enhances the capability of SBML for modeling biological systems with inherent uncertainty.
  • This extension supports more robust and realistic computational modeling in systems biology.
  • Enables better integration of stochastic data into standardized biological model descriptions.
