Experimental Progress on Layered Topological Semimetals
We review recent experimental progresses on layered topological materials,
mainly focusing on transitional metal dichalcogenides with various lattice
types including 1T, Td and 1T' structural phases. Their electronic quantum
states are interestingly rich, and many appear to be topological nontrivial,
such as Dirac/Weyl semimetallic phase in multilayers and quantum spin hall
insulator phase in monolayers. The content covers recent major advances from
material synthesis, basic characterizations, angle-resolved photoemission
spectroscopy measurements, transport and optical responses. Following those, we
outlook the exciting future possibilities enabled by the marriage of
topological physics and two dimensional van der Waals layered heterostructures.Comment: 2D Materials (2019
Chemical constituents, and pharmacological and toxicological effects of Cynomorium songaricum: An overview
Purpose: To review the chemical constituents, and the pharmacological and toxicological effects of Cynomorium songaricum (C. songaricum) and explore its potentials for further development as an alternative medicine.Methods: A large number of research articles related to “Cynomorium songaricum” “pharmacological effects”, “toxicological effects” and “chemical composition” in English and Chinese language were retrieved through an extensive literature review using various electronic databases including Medline(1966 - 2017) and EMBASE (1980 - 2017).Results: Ethyl acetate and aqueous extracts of C. songaricum have promising pharmacological activities, due to the presence of various flavonoids, triterpenes and polysaccharides. In addition to promising effects against inflammation, aging, fatigue, viruses and cancer,/ihas a protective effect on the nervous system and regulates hormones and immune functions. Oxidative regulation of hormone levels has a certain correlation with its pharmacological activities, e.g., cognitive functions, but its mechanism is not yet known, indicating the need for further research. Toxicity studies on C. songaricum have shown that it is not genotoxic to animals, but further toxicological studies are required to ascertain its safety in clinical use.Conclusion: C. songaricum is a biologically important plant which has many proven bioactivities; however, it requires further studies to determine the mechanistic aspects of its pharmacological effects.Keywords: Cynomorium, Chemical constituents, Inflammation, Aging, Fatigue, Virus, Tumor, Toxicological effec
What Matters: Agreement Between U.S. Courts of Appeals Judges
Federal courts are a mainstay of the justice system in the United States. In this study, we analyze 387,898 cases from U.S. Courts of Appeals, where judges are randomly assigned to panels of three. We predict which judge dissents against co-panelists and analyze the dominant features that predict such dissent with a particular attention to the biographical features that judges share. Random forest, a method developed in Breiman (2001), achieves the best classification. Dissent is predominantly driven by case features, though personal features also predict agreement
The Characteristics of TCM Clinical Trials: A Systematic Review of ClinicalTrials.gov
Objective. The aim of this review is to characterize current status of global TCM clinical trials registered in ClinicalTrials.gov. Methods. We examined all the trials registered within ClinicalTrials.gov up to 25 September 2015, focusing on study interventions to identify TCM-related trials, and extracted 1,270 TCM trials from the data set. Results. Overall, 691 (54.4%) trials were acupuncture, and 454 (35.8%) trials were herbal medicines. Differences in TCM trial intervention types were also evident among the specific therapeutic areas. Among all trials, 55.7% that were small studies enrolled <100 subjects, and only 8.7% of completed studies had reported results of trials. As for the location, the United States was second to China in conducting the most TCM trials. Conclusion. This review is the first snapshot of the landscape of TCM clinical trials registered in ClinicalTrials.gov, providing the basis for treatment and prevention of diseases within TCM and offering useful information that will guide future research on TCM
