  2. Fold change - Wikipedia

    en.wikipedia.org/wiki/Fold_change

    For example, on a plot axis showing log 2 fold changes, an 8-fold increase will be displayed at an axis value of 3 (since 2 3 = 8). However, there is no mathematical reason to only use logarithm to base 2, and due to many discrepancies in describing the log 2 fold changes in gene/protein expression, a new term "loget" has been proposed. [10]

  3. Crystallographic restriction theorem - Wikipedia

    en.wikipedia.org/wiki/Crystallographic...

    Compatible: 6-fold (3-fold), 4-fold (2-fold) Incompatible: 8-fold, 5-fold. Now consider an 8-fold rotation, and the displacement vectors between adjacent points of the polygon. If a displacement exists between any two lattice points, then that same displacement is repeated everywhere in the lattice.

    [3] [4] [6] In the case of the serotonin 5-HT 2A receptor, this was 6- to 14-fold higher than DOB, DOI, and DOC and was 9-fold higher than DOPR. [3] [6] In another study, DOHx showed 25-fold higher affinity for the serotonin 5-HT 2A receptor than DOM or DOET, 23- to 28-fold higher affinity than DOPR and DOBU, and 2.8-fold higher affinity than ...

  5. Rotational symmetry - Wikipedia

    en.wikipedia.org/wiki/Rotational_symmetry

    Therefore, the number of 2-, 3-, 4-, and 6-fold rotocenters per primitive cell is 4, 3, 2, and 1, respectively, again including 4-fold as a special case of 2-fold, etc. 3-fold rotational symmetry at one point and 2-fold at another one (or ditto in 3D with respect to parallel axes) implies rotation group p6, i.e. double translational symmetry ...

  6. Volcano plot (statistics) - Wikipedia

    en.wikipedia.org/wiki/Volcano_plot_(statistics)

    This plot is colored such that those points having a fold-change less than 2 (log 2 = 1) are shown in gray. In statistics, a volcano plot is a type of scatter-plot that is used to quickly identify changes in large data sets composed of replicate data. [1] [2] It plots significance versus fold-change on the y and x axes

  7. Point groups in three dimensions - Wikipedia

    en.wikipedia.org/wiki/Point_groups_in_three...

    An object of C 3v symmetry under one of the 3-fold axes gives rise under the action of T d to an orbit consisting of four such objects, and T d corresponds to the set of permutations of these four objects. T d is a normal subgroup of O h. See also the isometries of the regular tetrahedron. T h, (3*2) [3 +,4] 2/m 3, m 3 order 24: pyritohedral ...

    Huawei's new trifold phone got more than 2 million preorders in a few hours, just before Apple is set to announce new iPhones. Shubhangi Goel. September 9, 2024 at 1:15 AM.

  9. Coordination number - Wikipedia

    en.wikipedia.org/wiki/Coordination_number

    For example, with bidentate nitrate ions as ligands, Ce IV and Th IV form the 12-coordinate ions [Ce(NO 3) 6] 2− (ceric ammonium nitrate) and [Th(NO 3) 6] 2−. When the surrounding ligands are much smaller than the central atom, even higher coordination numbers may be possible. One computational chemistry study predicted a particularly ...
