It was first isolated from <i>Litsea</i> sp. (Jiang et al. 2017). Conidia produced by <i>P. litseae</i> are oblong to ellipsoidal and aseptate with two large polar guttules (Jiang et al. 2017). This species as an endophytic fungus in <i>Coptis chinensis</i> exhibited obvious inhibition against methicillin-resistant <i>Staphylococcus aureus</i> (Ming et al. 2022). In the present study, two strains were isolated from diseased tea plant leaves. This is the first report of <i>P. litseae</i> causing leaf blight on <i>C. sinensis</i>.</p>Published as part of <i>Wang, Yuchun, Tu, Yiyi, Chen, Xueling, Jiang, Hong, Ren, Hengze, Lu, Qinhua, Wei, Chaoling & Lv, Wuyun, 2024, Didymellaceae species associated with tea plant (Camellia sinensis) in China, pp. 217-251 in MycoKeys 105</i> on pages 217-251, DOI: 10.3897/mycokeys.105.11953

Get PDFDue to its desirable material properties, Silicon Carbide (SiC) hasbecome an alternative material to replace Si for MicroelectromechanicalSystems (MEMS) applications in harsh environments. To promote SiC MEMSdevelopment towards future cost-effective products, main technology areas inmaterial deposition and processes have attracted significant interest. Thedevelopments in these areas have contributed to the rapid emergence of SiCMEMS prototypes. In this paper, we give an overview of the importantdevelopments in SiC material formation and fabrication processes in recentyears. Some of the most interesting state-of-the-art SiC MEMS devices arereviewed. This highlights the major progresses in SiC MEMS developed thusfar. This paper also looks into the prospect of SiC MEMS drawing attention topotential issues

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.

Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
