Upstream Processing

Upstream Processing

Upstream processing represents a critical phase in biomanufacturing, wherein biological systems such as microorganisms, mammalian cells, or insect cells are cultivated to produce therapeutic proteins, vaccines, enzymes, or other biologically derived products. This phase encompasses all steps from the selection and genetic manipulation of the production organism to the cultivation of cells in bioreactors under tightly controlled environmental conditions.Host Selection and Genetic OptimizationThe...

Per-Unit Sequence Models

Per-Unit Sequence Models

An ideal Y-Y transformer, grounded through neutral impedances, displays per-unit sequence networks akin to those of a single-phase ideal transformer when subjected to balanced positive- or negative-sequence currents. These currents do not produce neutral currents, and their associated voltage drops.
Zero-sequence currents, which are identical in magnitude and phase, generate a neutral current, resulting in voltage drops across the neutral impedance and the low-voltage winding. If the...

Integration of Synaptic Events

Integration of Synaptic Events

Synaptic integration mainly includes the summation of graded potentials. Graded potentials, regardless of their type, cause subtle alterations in membrane voltage, resulting in either depolarization or hyperpolarization. These incremental changes, when combined or summed, can propel the neuron toward its threshold. Consider, for example, a membrane experiencing a +15 mV shift, causing it to depolarize from -70 mV to -55 mV. In this scenario, graded potentials govern the membrane's ability to...

Source Transformation

Source Transformation

Source transformation is a fundamental technique employed in circuit analysis, offering a valuable tool for simplifying complex electrical circuits. This technique involves the replacement of either a voltage source in series with a resistor by a current source in parallel with a resistor, or vice versa. The key concept here is that when the original sources are deactivated (turned off), the equivalent resistance at the circuit's end terminals remains the same.
It is essential to note that when...

Area of Science:

Medical Informatics
Computational Linguistics

Background:

The Unified Medical Language System (UMLS) integrates over 100 source vocabularies.
Discovering existing terms in the UMLS is crucial for integrating new sources.
Simple string matching is insufficient for comprehensive concept discovery.

Purpose of the Study:

To present a novel methodology for enhancing concept discovery in the UMLS.
To improve the identification of source terms during UMLS integration.

Main Methods:

Developed a methodology based on piecewise synonyms.
Created a general synonym dictionary derived from the UMLS.
Decomposed multi-word terms into component words.
Generated and recombined synonyms to expand matching candidates.

Main Results:

Demonstrated the methodology on an existing UMLS source.
Achieved a 34% improvement in concept discovery over simple string matching.

Conclusions:

The piecewise synonym methodology significantly enhances UMLS concept discovery.
This approach offers a more effective alternative to traditional string matching for term integration.
