AI3SD Video: The Application of Machine Learning in Molecular Spectroscopy Study
No full textOptical-spectroscopy provides powerful toolkits to decipher molecular structures and their configuration evolutions. However, the theoretical analysis of spectroscopic signals and connecting them with structural detail is a challenging task. Moreover, the intrinsic complexity of spectroscopic signals of molecular systems makes it difficult to correlate spectral characteristics with the underlying molecular structure and dynamics. Herein, we have developed data-driven machine learning (ML) protocols that can predict infrared (IR), ultraviolet/visible (UV/Vis) and Raman spectra of molecule systems with 3 to 5 orders of magnitude reduced computation cost compared to direct quantum chemistry calculations. A convolutional neural network (CNN) model was trained and tested on a dataset consisting 87993 spectra computed from protein peptide segments with α-helical, β-sheet, and other typical secondary structures. The secondary structure classification accuracy reached near 100% and over 98.7% on spectra sets of new segments extracted from the same and homologous proteins, respectively. Importantly, we demonstrate the ML protocol to realize cost-effective relations between spectra, structure, and chemical properties, i.e. spectra determination/prediction from structural information, and configuration or chemical properties determination/recognition from spectroscopic signals.1.

Remarks. A. yuanjiangensis sp. nov. keys to the Amynthas corticis -group (Sims & Easton, 1972), characterized by four spermathecal pores located intersegmentally in 5/6–8/9 and by holandry. By now, there are 109 species belonging into A. corticis -group totally (Nguyen et al. 2020a). The combined characters of medium-sized body, male pore on the top of a large raised pulvinate pad, no genital papillae in the spermathecal pore and male pore regions, intestinal caeca between simple and complex, prostate gland partially vestigial or developed, and rod-shaped spermathecal seminal chamber make this new species different from the species reported from China in A. corticis -group. This new species is similar to Amynthas fornicates (Gates, 1935) in medium-sized body, no genital papillae in the male pore region, and the arrangement of spermathecal pores. However, in A. yuanjiangensis sp. nov., the intestinal caeca are between simple and complex, the prostate glands are partially degenerated, and the spermathecal diverticulum shorter than the main spermathecal axis; however, in A. fornicates, the intestinal caeca are simple, the prostate glands are developed, and the spermathecal diverticulum is longer than the main spermathecal axis. A. yuanjiangensis sp. nov. is resemble Amynthas homochaetus (Chen, 1938) in the large raised pulvinate pad of male pore area, no genital papillae on spermathecal pore region and male pore region especially. But A. yuanjiangensis sp. nov. is clearly distinguished from A. homochaetus by the following characters: 1) the intestinal caeca in A. homochaetus are simple, but in this new species, they are between simple and complex; 2) the prostate glands in A. homochaetus are well developed, but in the new species, they are partially degenerated; 3) the seminal chambers in A. homochaetus are ovoid, but those in the new species are rod-shaped. Amynthas disperses Sun & Qiu, 2018 and A. yuanjiangensis sp. nov. have both been collected in several localities in South China, and share some characters (e.g. megium-sized body, the area of male pore porophore is bigger, partially vestigial prostate gland, and band- or rod-shaped seminal chamber), but they are different from each other in the following ways: 1) the first dorsal pore is located at 10/11 or 11/12 on A. disperses, but always at 11/ 12 in the new species; 2) small genital papillae are always present in the spermathecal pore and male pore region in A. disperses, but there are no genital papillae in the new species; 3) the intestinal caeca in A. disperses are simple, but those in this new species are between simple and complex; 4) the spermathecal diverticulum is about as long as the main spermathecal axis in A. disperses, but shorter than the main spermathecal axis in the new species.Published as part of Sun, Jing, Jiang, Ji-Bao, Wu, Juzhen, Yuan, Zhu & Qiu, Jiang-Ping, 2021, Three new widely distributed and polymorphic species of Amynthas earthworms (Oligochaeta, Clitellata, Megascolecidae) from South China, pp. 457-474 in Zootaxa 4938 (4) on pages 464-467, DOI: 10.11646/zootaxa.4938.4.5, http://zenodo.org/record/457494

Spermathecal pores three pairs, in 6/7–8/9, intersegmental, about 0.33 of circumference ventrally apart; conspicuous, eye-like (Fig. 5A). Two genital papillae always longitudinally placed and posterior to the setae AA in VII and VIII in holotype and paratypes; an extra two pairs of papillae present in paratype C-AH201609-03, and each pair longitudinally placed slightly medial to the spermathecal pore on VIII; no genital papillae on paratype C-FJ 201101 -03. Secondary male pores in XVIII, 0.33 of circumference ventrally apart, surrounded by three skin folds, opening to small copulatory pouches visible only within the body wall, no penial body in the pouch. Male papillae variable, holotype with three small, flattopped papillae aligned in a curve medial to each male opening and concave laterally, as well as three ventromedial and post-setal papillae transversely located on XVIII, no penial body in the pouch; paratypes with two small, flat-toped papillae adjacent to the anterior and posterior margins of each copulatory pouch (Fig. 5B). Female pore single mid-ventral in XIV, milk-white, elliptical, slightly swollen. Internal characters. Septa 8/9–9/10 absent, 5/6–7/8 thickened and muscular, 10/11–12/13 thicker than those following.

Prostate gland well-developed, coarsely lobate, in XVI–XXI, a small inverted U-shaped duct, stout, in XVIII (Fig. 5C). No visible accessory glands on XVIII. Female organs: Spermathecae three pairs in VII–IX, about 2.4 mm long; ampulla heart-shaped, distinctly marked off from its duct, duct as long as half of ampulla; diverticulum about 2.0 mm long, distal ½ dilated into rod-shaped seminal chamber; no nephridia on spermathecal ducts (Fig. 5D). DNA barcodes. GenBank accession numbers KY774380 (C-FJ 201008 -02, holotype), KY774381 (C- FJ 201101 -03, paratype), KY774382 (C-AH201610-04, paratype), KY774383 (C-AH201609-03, paratype), KY774384 (C-AH201610-03, paratype). Remarks. The new species keys to the Metaphire houlleti -group (Sims & Easton 1972). This group is diagnosed by three pairs of intersegmental spermathecal pores in 6/7–8/9, male pores on XVIII, bithecate, and post-clitellar genital markings not present in 17/18 and/or 18/19. The specimens were collected from a wide area: six locations in three provinces (Fujian, Jiangxi and Anhui, China). Despite extensive literature searches, no cosmopolitan species that were a close match were found. However, three Chinese endemic species slightly resemble the new species. They are Metaphire tschiliensis kokoanus (Chen & Fong, 1975), Metaphire tschiliensis lanzhouensis (Feng, 1984) and Metaphire ptychosiphona Qiu & Zhong, 1993. Even though these four species all have three pairs of spermathecal pores in 6/7–8/9 and a pair of small male copulatory pouches, each of the three slightly similar species has its own distinctive characteristics when compared with M. sanmingensis, sp. nov. This medium-sized new species normally has papillae in the spermathecal pore region, well-developed prostate glands, and a rod-shaped diverticulum seminal chamber; M. tschiliensis kokoanus has a different arrangement of spermathecal pore region papillae, and its diverticulum seminal chamber is longer than the main spermathecal axis (Chen et al. 1975); M. tschiliensis lanzhouensis has a larger body, up to 310 mm long and 7 mm wide, no genital papillae in the spermathecal pore region, small prostate glands, and a twisted seminal chamber (Feng 1984); M. ptychosiphona has a larger body, up to 295 mm long and 9 mm wide, no genital papillae in spermathecal pore region, small prostate glands and a twisted seminal chamber (Qiu & Zhong 1993).Published as part of Sun, Jing, Jiang, Ji-Bao, Bartlam, Scott, Qiu, Jiang-Ping & Hu, Feng, 2018, Four new Amynthas and Metaphire earthworm species from nine provinces in southern China, pp. 287-301 in Zootaxa 4496 (1) on pages 296-298, DOI: 10.11646/zootaxa.4496.1.24, http://zenodo.org/record/144681
