Resting Membrane Potential01:24

Resting Membrane Potential

22.1K
The relative difference in electrical charge, or voltage, between the inside and the outside of a cell membrane, is called the membrane potential. It is generated by differences in permeability of the membrane to various ions and the concentrations of these ions across the membrane.
The Inside of a Neuron is More Negative
The membrane potential of a cell can be measured by inserting a microelectrode into a cell and comparing the charge to a reference electrode in the extracellular fluid. The...

Resting Potential Decay01:15

Resting Potential Decay

6.5K
The resting membrane potential of a neuron (-70mV) is sustained due to the selective ion permeability of the membrane. At the resting potential, the membrane is slightly permeable to ions like sodium (Na+) and chloride (Cl−) and highly permeable to potassium ions (K+). Differences in the ions' concentration inside the cell compared to the outside are maintained by membrane transport proteins like channels and pumps.
At rest, the K+ is the main ion that moves across the membrane...

Pressure Variation in a Fluid at Rest01:11

Pressure Variation in a Fluid at Rest

857
In a fluid at rest, the pressure at any point beneath the fluid surface depends solely on the depth, not on the container's shape or size. This principle, known as hydrostatic pressure, arises because, in stationary fluids, there is no acceleration, meaning the forces within the fluid balance out. Only vertical forces, caused by the weight of the fluid above, contribute to pressure changes with depth.
When measuring pressure at two different levels within the fluid, the difference in...

The de Broglie Wavelength

33.8K
In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

Area of Science:

  • Life Sciences
  • Bioinformatics
  • Computational Biology

Background:

  • Full-text search in life-science databases offers flexibility but can yield imprecise results.
  • Existing query assistance systems rely on laborious manual curation or restricted data access.
  • Privacy concerns limit approaches that infer related queries from user profiles.

Purpose of the Study:

  • To introduce LAILAPS-QSM, a novel machine learning approach for enhancing life-science database query suggestions.
  • To overcome the limitations of traditional query assistance systems by reconstructing linguistic contexts.

Main Methods:

  • LAILAPS-QSM preprocesses text records from databases (e.g., PubMed, UniProt) to compute customized distributed word vectors.
  • These word vectors are used to infer and suggest alternative, contextually relevant keyword queries.
  • Quality assessment involved plant science use cases, evaluating suggestions against expert-curated categories using ontology term similarities.

Main Results:

  • LAILAPS-QSM achieved a mean information content similarity of 0.70 for 15 representative queries.
  • 34% of LAILAPS-QSM suggestions scored above 0.80 in information content similarity.
  • Human expert suggestions achieved a higher similarity score of 0.90.

Conclusions:

  • LAILAPS-QSM offers a viable machine learning-based solution for improving query suggestions in life-science databases.
  • The system is available as a toolset for custom services or a general-purpose RESTful web service.
  • The software is implemented in Java for efficient performance and is open-source.
