Distribution Reliability and Automation

Distribution Reliability and Automation

Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...

Co-activators and Co-repressors

Co-activators and Co-repressors

Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...

tRNA Activation

tRNA Activation

Aminoacyl-tRNA synthetases are present in both eukaryotes and bacteria. Though eukaryotes have 20 different aminoacyl-tRNA synthetases to couple to 20 amino acids, many bacteria do not have genes for all of these aminoacyl-tRNA synthetases. Despite this, they still use all 20 amino acids to synthesize their proteins. For instance, some bacteria do not have the gene encoding the enzyme that couples glutamine with its partner tRNA. In these organisms, one enzyme adds glutamic acid to all of the...

Activation Energy

Activation Energy

Activation energy is the minimum amount of energy necessary for a chemical reaction to move forward. The higher the activation energy, the slower the rate of the reaction. However, adding heat to the reaction will increase the rate, since it causes molecules to move faster and increase the likelihood that molecules will collide. The collision and breaking of bonds represents the uphill phase of a reaction and generates the transition state. The transition state is an unstable high-energy state...

Eukaryotic Transcription Activators

Eukaryotic Transcription Activators

Transcription activators are proteins that promote the transcription of genes from DNA to RNA. In most cases, these proteins contain two separate domains ‒ a domain that binds to DNA and a domain for activating transcription; however, in some cases, a single domain is responsible for both binding and activation of transcription, as seen in the glucocorticoid receptor and MyoD.
The binding domains are capable of recognizing and interacting with regulatory sequences on the DNA. These...

Secondary Active Transport

Secondary Active Transport

One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this process is sodium (Na+), which is typically present in higher concentrations extracellularly than in the cytosol. Such a concentration difference is due, in part, to the action of an enzyme “pump” embedded in the cellular membrane that actively expels Na+ from a cell. Importantly, as this pump contributes to the high concentration of...

Area of Science:

Neuroscience
Computational Neuroscience

Background:

Cortical neurons process synaptic inputs, including synchronized events.
Synchronized synaptic events can induce persistent neural activity, characterized by prolonged membrane depolarization.
Manual detection of these events in large datasets is inefficient and subjective.

Purpose of the Study:

To develop a software package for the systematic and objective detection of persistent neural activity.
To automate the analysis of large time-series electrophysiological data.
To provide researchers with a tool to overcome the limitations of manual event detection.

Main Methods:

Development of a MATLAB-based software package.
Implementation of a multi-step analysis pipeline: pre-processing, event detection, user-interactive review, and filtering/graphing.
Focus on analyzing time-series data from cortical neurons.

Main Results:

A core software package for objective detection of persistent neural activity was created.
The software enables systematic analysis of large electrophysiological datasets.
The developed tool reduces the labor associated with identifying persistent membrane potential events.

Conclusions:

The developed MATLAB software offers an efficient and objective method for detecting persistent neural activity.
This tool facilitates the systematic analysis of large-scale neural data, advancing neuroscience research.
