Sequential Synthesis and Secondary Structure Analysis of Two Classes of Perylene Bisimide Oligomers
<p>Data to report <a title="DOI URL" href="https://doi.org/10.1021/acs.orglett.4c01928">https://doi.org/10.1021/acs.orglett.4c01928</a><a title="DOI URL" href="https://doi.org/10.1021/acs.orglett.4c01928">:</a></p> <p>An iterative step-by-step synthetic approach is employed to form perylene bisimide (PBI) oligomers with defined size by connecting the PBI units through their imide positions via a benzyl linker. The versatility of this approach was showcased by its successful implementation on two different PBI building blocks to achieve two separate series of oligomers (up to the pentamer) with modulated conformations; the one with an open random coil oligomer and the other with an H-type foldamer architecture.</p>
Sentence Compression Using Constituency Analysis of Sentence Structure
<p>Simply stated, producing a shorter format of a given sentence is the task of sentence compression. The challenging part of this process is preserving the most important information as well as grammaticality in the compressed version. There are different ways of achieving this purpose, among which, we try to come up with a rule-based extractive method for the Persian language. Our approach involves identifying removable constituents within a sentence and eliminating them in the order of insignificance until the desired compression rate is achieved. To develop this method, we created a compression corpus of 600 sentences from two available treebanks in the Persian language. 300 sentences are used for extracting deletion rules as training data and the remaining 300 are used for testing the system. Its applicability even using a limited training corpus and user’s authority over the input compression rate are the benefits of the presented method in this paper. Additionally, our compression system is open-ended, enabling the addition or removal of deletion rules to refine its performance. The results suggest applying rule-based methods for language processing tasks can be quite efficient in syntactically rich languages such as Persian, yielding desirable outcomes and offering distinct advantages.</p>
Figure 6 in A geometric morphometric approach to the analysis of the shape variability of the haptoral attachment structures of Ligophorus species (Platyhelminthes: Monogenea)
Figure 6. Combination of the outlines of all dorsal anchors of each analyzed Ligophorus species (other haptoral structures outlines see http://marineparasites.org/morphometry/
Figure 5 in A geometric morphometric approach to the analysis of the shape variability of the haptoral attachment structures of Ligophorus species (Platyhelminthes: Monogenea)
Figure 5. Cluster (A, C) and PC analysis (B, D) of the combinations of four harmonics for each dorsal and ventral anchors, and ventral bar obtained for each Ligophorus specimens. Upper graphs (A, B) are based on the size-invariant EFDs; lower graphs (C, D) – on the size-considered EFDs.
Figure 4 in A geometric morphometric approach to the analysis of the shape variability of the haptoral attachment structures of Ligophorus species (Platyhelminthes: Monogenea)
Figure 4. PCA of the size-invariant (A, C, E) and size-considered (B, D, F) harmonics of the dorsal (А, B) and ventral (C, D) anchors, and the ventral bars (E, F) of Ligophorus species. All graphs are based on fifty harmonics. Keys: dots – dorsal anchors; triangles – ventral anchors; rhombus – ventral bars.
Figure 2. A in A geometric morphometric approach to the analysis of the shape variability of the haptoral attachment structures of Ligophorus species (Platyhelminthes: Monogenea)
Figure 2. A After the automatic normalization, the outlines of anchors still have different orientation of the blades, different positions of the digitization starting point and directions of digitization; this affects the signs of the first harmonic components, which are shown in pink rectangle, and the signs of identical components differ. B, C After manual correction of the orientation of anchors (B) and bars (C), the outlines and signs of first harmonic components are identical.
Figure 3 in A geometric morphometric approach to the analysis of the shape variability of the haptoral attachment structures of Ligophorus species (Platyhelminthes: Monogenea)
Figure 3. PCA of the size-invariant (A, B) and the size-considered (C, D) harmonics of all dorsal and ventral anchors of analyzed Ligophorus species. Left graphs (A, C) are based on fifty harmonics; right graphs (B, D) – on four ones. Keys: dots – dorsal anchors; triangles – ventral anchors.
Figure 1. A in A geometric morphometric approach to the analysis of the shape variability of the haptoral attachment structures of Ligophorus species (Platyhelminthes: Monogenea)
Figure 1. A Ligophorus szidati dorsal (top) and ventral (bottom) anchors were outlined by cubic Bezier polylines and stored in SVG files. B ElFourier computer program converted digitized outlines into 50 EFDs. Only first four harmonics are visible at the screenshot's bottom; the negative components of harmonics are colored in light gray. The restored outline perfectly satisfies the shape of anchor (red line around gray anchor). At the left side used anchors are shown; they differ by orientation of blades and direction of digitization; outlines oriented counterclockwise are filled.

(1729) Venice Biennale Danish pavilion, Venice, I - Structural analysis report
<p>This report contains structural analysis results of the textile membrane installation at the Danish Pavilion of the Venice Biennale 2018. Load assumptions, support reactions, deflections, reaction forces and stress state of the main load bearing members are presented.<br> Basis for the design are the EN 1990 (Basis of structural design) [1], EN 1991 (Actions on structures) [2], EN 1993 (Design of steel structures) [3] and DIN EN 13782 (Temporary structures) [4].<br> The installation is placed at the “Giardini della Biennale” in Venice as part of the Biennale exhibition which will run from May until November. The loads acting upon the structure are partially reduced due to the temporary nature of the installation.</p>
