Imprinting01:22

Imprinting

11.9K
Behavioral imprinting is observed in some newborn animals and occurs when they develop strong and specific attachments to another animal (usually a parent) following brief, early-life exposures. Offspring imprint onto parents within a brief period after birth or hatching; this time window is called the critical period. Once imprinting occurs, the bond established between the parents and their offspring is usually long-lasting.

Entropy02:39

Entropy

38.4K
Salt particles that have dissolved in water never spontaneously come back together in solution to reform solid particles. Moreover, a gas that has expanded in a vacuum remains dispersed and never spontaneously reassembles. The unidirectional nature of these phenomena is the result of a thermodynamic state function called entropy (S). Entropy is the measure of the extent to which the energy is dispersed throughout a system, or in other words, it is proportional to the degree of disorder of a...

Scanning Electron Microscopy01:07

Scanning Electron Microscopy

6.1K
A scanning electron microscope (SEM) is used to study the surface features of a sample by using an electron beam that scans the sample surface in a two-dimensional manner. Typically, areas between ~1 centimeter to 5 micrometers in width can be imaged. SEM can be used to image bacteria, viruses, tissues as well as larger samples like insects. Conventional SEM gives a magnification ranging from 20X to 30,000X and spatial resolution of 50 to 100 nanometers.

Entropy

3.9K
The first law of thermodynamics is quantitatively formulated via an equation relating the internal energy of a system, the heat exchanged by it, and the work done on it. A quantitative formulation of the second law of thermodynamics leads to defining a state function, the entropy.
When an ideal gas expands isothermally, the disorder in the gas increases. From the molecular perspective, the gas molecules have more volume to move around in.
Consider an infinitesimal step in the expansion, which...

Composite Bodies00:55

Composite Bodies

1.6K
A composite body is a body made up of multiple parts, connected to form a larger, unified object. Each part has its own weight and center of gravity, which must be considered to determine the center of gravity of the composite body. In cases where the density or specific weight is constant, the center of gravity coincides with the centroid.
Composite bodies have widespread applications in mechanical engineering, from automobiles to aircraft to rockets. For example, an automobile wheel comprises...

Design Example: Maintaining Level of an Embankment

545
Constructing a roadway embankment over uneven terrain requires precise leveling to ensure stability and proper drainage. Surveyors use a leveling instrument and staff to calculate ground elevations and determine the required fill material at each point along the embankment alignment.The process begins by positioning a leveling instrument near a benchmark with a known elevation. A backsight reading establishes the instrument height, which serves as a reference for subsequent measurements. A...

Area of Science:

  • Bioinformatics
  • Computer Science
  • Semantic Web Technologies

Background:

  • The bioinformatics field requires methods for classifying and relating heterogeneous services.
  • The Semantic Web aims to address this challenge with standardized semantic service descriptions.
  • Combining semantic knowledge with planning methods can automate workflow composition.

Purpose of the Study:

  • To apply a synthesis methodology for semantic-based composition of European Molecular Biology Open Software Suite (EMBOSS) services.
  • To compare manual and automatic domain setup approaches for EMBOSS service composition.
  • To evaluate the effectiveness of domain models in simplifying the use of large, heterogeneous service collections.

Main Methods:

  • Utilized the Bio-jETI workflow management framework for semantic-based composition.
  • Developed two EMBOSS synthesis domain setups: manual and automatic derivation from ACD files and EDAM ontology.
  • Applied synthesis methodology to EMBOSS services for workflow composition.

Main Results:

  • Domain models and synthesis methodology significantly simplify working with the EMBOSS service collection.
  • Manual domain setup provides intuitive, high-level semantic descriptions.
  • Automatic derivation from ACD files and EDAM ontology is efficient but may miss essential service connections.

Conclusions:

  • Adequate domain modeling necessitates incorporating extensive domain knowledge beyond technical aspects.
  • Defining semantically appropriate service and type descriptions is challenging but crucial.
  • The bioinformatics community is progressing towards a Life Science Semantic Web for automatic service composition.
