  2. Valence issue - Wikipedia

    en.wikipedia.org/wiki/Valence_issue

    Position issues are an alternative to valence issues, as position issues create disagreement among voters because a broad consensus on the issue is lacking. [20] Since position issues are divisive issues they consequently separate potential voters into distinct voting blocs that may support or oppose a way of dealing with the position issue at hand. [21]

  3. List of unsolved problems in biology - Wikipedia

    en.wikipedia.org/wiki/List_of_unsolved_problems...

    Developmental psychobiology posed this question since the lack of knowledge about the precise coordination of all cells, even those not related anatomically, in space and time during the embryonic period does not allow us to understand what forces at the cellular level coordinate four very general classes of tissue deformation, namely: tissue ...

  4. Cross-linking immunoprecipitation - Wikipedia

    en.wikipedia.org/wiki/Cross-linking_immuno...

    Cross-linking and immunoprecipitation (CLIP, or CLIP-seq) is a method used in molecular biology that combines UV crosslinking with immunoprecipitation in order to identify RNA binding sites of proteins on a transcriptome-wide scale, thereby increasing our understanding of post-transcriptional regulatory networks.

  5. Valence populism - Wikipedia

    en.wikipedia.org/wiki/Valence_populism

    Valence populism is a form of populism linked to political parties or politicians whose positions cannot be placed on the left–right political spectrum and mainly promote valence issues that are widely approved by voters. Such popular valence issues include anti-corruption, government transparency, democratic reform, and moral integrity.

  6. Valence (psychology) - Wikipedia

    en.wikipedia.org/wiki/Valence_(psychology)

    The use of the term in psychology entered English with the translation from German ("Valenz") in 1935 of works of Kurt Lewin.The original German word suggests "binding", and is commonly used in a grammatical context to describe the ability of one word to semantically and syntactically link another, especially the ability of a verb to require a number of additional terms (e.g. subject and ...

  7. iCLIP - Wikipedia

    en.wikipedia.org/wiki/ICLIP

    Moreover, iMaps provides a free CLIP analysis web platform and well-curated community database to facilitate studies of RNA regulatory networks across organisms, with a backend based on the Nextflow pipeline. It is applicable to the many variant protocols of CLIP (such as iCLIP, eCLIP, etc), and can be used to analyse unpublished data in a ...

  8. VSEPR theory - Wikipedia

    en.wikipedia.org/wiki/VSEPR_theory

    The steric number of a central atom in a molecule is the number of atoms bonded to that central atom, called its coordination number, plus the number of lone pairs of valence electrons on the central atom. [11] In the molecule SF 4, for example, the central sulfur atom has four ligands; the coordination number of sulfur is four. In addition to ...

    However, this does not indicate that the element in question is required for functioning. The element allows the system to function, but its presence is not required in order for the system to function. Tests of sufficiency in biology are used to determine if the presence of an element permits the biological phenomenon to occur.
