Symmetry breaking in spin spirals and skyrmions by in-plane and canted magnetic fields
<p>The influence of in-plane and canted magnetic fields on spin spirals and skyrmions in atomic bilayer<br> islands of palladium and iron on an Ir(111) substrate is investigated by scanning tunneling microscopy<br> at low temperatures. It is shown that the spin spiral propagation direction is determined by the island’s<br> border which can be explained by equilibrium state calculations on a triangular lattice.Wefind a<br> different response of spin spirals to in-plane magnetic fields for a propagation direction parallel to the<br> applied field as compared to perpendicular, which originates from their cycloidal nature. As a result,<br> the spin spiral propagation direction may be reorientated by in-plane fields. Furthermore, it is<br> demonstrated that also skyrmions are distorted in canted fields which allows to determine the sense of<br> magnetization rotation as enforced by the interfacial Dzyaloshinskii–Moriya interaction.</p>

Data for "Directional asymmetry and direction-giving factors: lessons from flowers with complex symmetry"
<p>These are the raw data associated with the following publication:</p> <p>Budečević, S., S. Manitašević Jovanović, A. Vuleta, B. Tucić, and C. P. Klingenberg. 2022. <strong>Directional asymmetry and direction-giving factors: lessons from flowers with complex symmetry</strong>. Evolution & Development: advance online.<br> <a href="https://doi.org/10.1111/ede.12402">https://doi.org/10.1111/ede.12402</a></p> <p><strong>Abstract: </strong>Directional asymmetry is a systematic difference between the left and right sides for structures with bilateral symmetry, or a systematic differentiation among repeated parts for complex symmetry. This study explores factors that produce directional asymmetry in the flower of <em>Iris pumila</em>, a structure with complex symmetry that makes it possible to investigate multiple such factors simultaneously. The shapes and sizes of three types of floral organs, the falls, standards, and style branches, were quantified using the methods of geometric morphometrics. For each flower, this study recorded the compass orientations of floral organs as well as their anatomical orientations relative to the two spathes subtending each flower. To characterize directional asymmetry at the whole-flower level, differences in the average sizes and shapes according to compass orientation and relative orientation were computed, and the left–right asymmetry was also evaluated for each individual organ. No size or shape differences within flowers were found in relation to anatomical position, which may relate to the terminal position of flowers in <em>Iris pumila</em>, so that there was no evidence of any adaxial–abaxial polarity (which is very prominent in many other taxa). There was clear directional asymmetry of shape in relation to compass orientation, presumably driven by a consistent environmental gradient such as solar irradiance. There was also clear directional asymmetry between left and right halves of every floral organ, most likely related to the arrangement of organs in the bud. These findings indicate that there are different factors acting to produce directional asymmetry at different levels. In conventional analyses, these effects would be impossible to disentangle from each other and would probably be included as part of fluctuating asymmetry.</p> <p><strong>Data included</strong></p> <p>This data set includes landmark data for the falls, standards, and style branches of flowers of <em>Iris pumila</em>, as well as information about the compass orientation of each flower part, the compass orientation of the outer spathe of the respective flower, and the orientation of the flower part relative to the outer spathe, as described in the paper.</p> <p>The plants and flowers considered in this study have been sequentially numbered specifically for this study, and the identifiers for the floral parts use this numbering system. The numbers are consistent between the different flower parts included in the study.</p> <p>Files included:</p> <p><strong>fall_coord.txt</strong>: Landmark coordinates for the falls.

Four-fold rotational symmetry in art: example n.2
<p>The Halaf culture is a prehistoric period which lasted between about 6100 BC and 5100 BC. The period is the ontinuous evolution of the earlier Pottery Neolithic. Its location is mainly in the fertile valley of the Khabur River (Euphrates), although Halaf-influenced material is found throughout Greater Mesopotamia, The image shows Halafian wave with a four-fold symmetric decoration.

Four-fold rotational symmetry in art: example n.3
<p>The Samarra culture is a Late Neolithic culture of northern Mesopotamia. The figure shows a bowl (ca. 4000 BC) on exhibit at the Vorderasiatisches Museum, Berlin. The figure has been obtained from a picture taken by Dbachmann, a courtesy for Wikimedia.org - commons.wikimedia.org/wiki/File:Samarra_bowl.jpg. The given description tells that the bowl was found by Ernst Herzfeld in the 1911-1914 campaign. It is also told that the design shows four fish being caught by four birds. This is the four-fold symmetry here mentioned.in the tile. The dscription given in Wikimedia is also stressing that "as is typical of cultures from this region, the use of a base six numerical system can be seen in the lines surrounding the bowl, so that there are a total of 120 lines, or four quarters with 30 lines each".</p>

The symmetry spectrum in a hybridising, tropical group of rhododendrons
<p>Many diverse plant clades possess bilaterally symmetrical flowers and specialized pollination syndromes suggesting these traits may promote diversification. We examine the evolution of diverse floral morphologies and the association with diversification history in a species-rich tropical radiation of <em>Rhododendron</em>. We used restriction-site associated DNA sequencing on 114 taxa from <em>Rhododendron</em> sect. <em>Schistanthe</em> to reconstruct phylogenetic relationships, infer colonization of Southeast Asia and examine hybridization. We then captured and quantified floral variation using geometric morphometric analyses which we interpret in a phylogenetic context. We uncovered phylogenetic complexity caused by introgression within and between clades. Morphometric analyses revealed flower symmetry to be a morphological continuum without a clear transition from radial to bilateral symmetry. The largest radiation of tropical <em>Rhododendron</em> species is associated with an expansion into novel floral morphological space as species diversified in New Guinea about 6 million years ago. Our results showed that the recent radiation of tropical <em>Rhododendron</em> is a consequence of hybridization, genetic isolation caused by mountain building, and the evolution of floral novelty. Floral variation evolved via changes to multiple components of the corolla that are only recognized in geometric morphometrics with both front and side views of flowers.</p>

In-house high energy remote SAD-phasing using the magic triangle: how to tackle the P1 low symmetry using multiple orientations on the same human IBA57 crystal to increase multiplicity.
<p>The dataset named IBA57-I3C.zip contains pck diffraction images of 9 runs (orientations) of a human IBA57 crystal soaked with 5-amino-2,4,6-triiodoisophthalic acid (I3C) collected on an in-house source. Multiple orientations (runs) of the very same triclinic crystal have been exploited to acquire sufficient real data multiplicity for SAD-phasing. Each folder named run* contains the pck images and the relevant XDS.INP file for processing. The file runs.txt in the top directory gives the phi, kappa, omega and theta details on each of the 9 runs.</p> <p>The dataset named IBA57-native.zip contains pck images of 1 run (360 images around phi only) of a native human IBA57 crystal collected on the same in-house source and the relevant XDS.INP file for processing; this dataset is needed for SIRAS along with the I3C dataset.</p> <p> </p>
