Extraction: Advanced Methods

507
Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

Optimal Foraging

12.4K
How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.

Frequency-dependent Selection01:21

Frequency-dependent Selection

22.2K
When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

Extraction: Partition and Distribution Coefficients

2.6K
The distribution law or Nernst's distribution law is the law that governs the distribution of a solute between two immiscible solvents. This law, also known as the partition law, states that if a solute is added to the mixture of two immiscible solvents at a constant temperature, the solute is distributed between the two solvents in such a way that the ratio of solute concentrations in the solvents remains constant at equilibrium.
For extracting a solute from an aqueous phase into an...

The Scientific Method01:32

The Scientific Method

230.3K
The scientific method is a detailed, empirical problem-solving process used by biologists and other scientists. This iterative approach involves formulating a question based on observation, developing a testable potential explanation for the observation (called a hypothesis), making and testing predictions based on the hypothesis, and using the findings to create new hypotheses and predictions.
Generally, predictions are tested using carefully-designed experiments. Based on the outcome of these...

Area of Science:

  • Biomedical Informatics
  • Natural Language Processing
  • Information Retrieval

Background:

  • The growing volume of biomedical literature necessitates improved methods for information retrieval.
  • Accurate keyword extraction is vital for reproducible research but challenged by obscure terms and limited benchmarks.
  • Existing methods struggle with the complexity of biomedical text.

Purpose of the Study:

  • To introduce PubMedAKE, the largest author-assigned keyword extraction dataset for biomedical articles.
  • To provide a comprehensive benchmark for evaluating and developing automatic keyword extraction models.
  • To highlight the need for advanced automatic keyword extraction techniques in the biomedical domain.

Main Methods:

  • Construction of the PubMedAKE dataset using over 843,269 PubMed open access articles.
  • Inclusion of article titles, abstracts, and author-assigned keywords.
  • Evaluation of state-of-the-art baseline methods on the dataset.

Main Results:

  • PubMedAKE serves as the largest benchmark for keyword extraction in biomedical literature.
  • The dataset is sufficiently large for training deep neural networks.
  • Baseline methods demonstrate the potential but also the limitations of current approaches.

Conclusions:

  • The PubMedAKE dataset is a valuable resource for advancing automatic keyword extraction in biomedical research.
  • Further development of sophisticated keyword extraction algorithms is required.
  • Improved keyword extraction will enhance search accuracy and support research reproducibility.
