Phytoplasmas are obligate transkingdom bacterial parasites that infect a variety of plant species and replicate in phloem-feeding insects in the order Hemiptera, mainly leafhoppers (Cicadellidae). The insect capacity in acquisition, transmission, survival, and host range directly determines the epidemiology of phytoplasmas. However, due to the difficulty of insect sampling and the lack of follow-up transmission trials, the confirmed phytoplasma insect hosts are still limited compared with the identified plant hosts. Recently, quantitative polymerase chain reaction (qPCR)-based quick screening of 227 leafhoppers collected in natural habitats unveiled the presence of previously unknown phytoplasmas in six samples. In the present study, 76 leafhoppers, including the six prescreened positive samples, were further examined to identify and characterize the phytoplasma strains by semi-nested PCR. A total of ten phytoplasma strains were identified in leafhoppers from four countries including South Africa, Kyrgyzstan, Australia, and China. Based on virtual restriction fragment length polymorphism (RFLP) analysis, these ten phytoplasma strains were classified into four distinct ribosomal (16Sr) groups (16SrI, 16SrIII, 16SrXIV, and 16SrXV), representing five new subgroups (16SrI-AO, 16SrXIV-D, 16SrXIV-E, 16SrXIV-F, and 16SrXV-C). The results strongly suggest that the newly identified phytoplasma strains not only represent new genetic subgroup lineages, but also extend previously undiscovered geographical distributions. In addition, ten phytoplasma-harboring leafhoppers belonged to seven known leafhopper species, none of which were previously reported insect vectors of phytoplasmas. The findings from this study provide fresh insight into genetic diversity, geographical distribution, and insect host range of phytoplasmas. Further transmission trials and screening of new potential host plants and weed reservoirs in areas adjacent to collection sites of phytoplasma harboring leafhoppers will contribute to a better understanding of phytoplasma transmission and epidemiology.

This article theorizes the Zimbabwean writer Stanlake Samkange’s turn from the novel to philosophy as an effort to circumvent the representational pressure exerted by African cultural traumatization. In breaking with the novel form to coauthor a philosophical treatise called Hunhuism or Ubuntuism in the same year as Zimbabwe achieves independence (1980), Samkange advances a comportment-based, deontological alternative to the psychic or subjective model of personhood that anchors trauma theory. Revisiting the progression from his most achieved novel, The Mourned One, to Hunhuism or Ubuntuism thus offers fresh insight into the range of options available to independence-era writers for representing the relationship between African individuality and collectivity. At the same time, it suggests a complementary and overlooked relationship between novelistic and philosophical forms in an African context.

Moving Train

The unprecedented COVID-19 pandemic has caused a traffic tie-up across the world. In addition to home quarantine orders and travel bans, the social distance guideline of about six feet was enacted to reduce the risk of contagion. However, with recent life gradually returning to normal, the crisis is not over. In this research, a moving train test and a Gaussian puff model were employed to investigate the impact of wind raised by a train running on the transmission and dispersion of SARS-CoV-2 from infected individuals. Our findings suggest that the 2 m social distance guideline may not be enough; under train-induced wind action, human respiratory disease-carrier droplets may travel to unexpected places. However, there are deficiencies in passenger safety guidelines and it is necessary to improve the quantitative research in the relationship between train-induced wind and virus transmission. All these findings could provide a fresh insight to contain the spread of COVID-19 and provide a basis for preventing and controlling the pandemic virus, and probe into strategies for control of the disease in the future.

Eukaryotic cells rely on endocytosis to regulate their plasma membrane proteome and lipidome. Most eukaryotic groups, except fungi and animals, have retained the evolutionary ancient TSET complex as an endocytic regulator. Unlike other coatomer complexes, structural insight into TSET is lacking. Here, we reveal the molecular architecture of plant TSET [TPLATE complex (TPC)] using an integrative structural approach. We identify crucial roles for specific TSET subunits in complex assembly and membrane interaction. Our data therefore generate fresh insight into the differences between the hexameric TSET in Dictyostelium and the octameric TPC in plants. Structural elucidation of this ancient adaptor complex represents the missing piece in the coatomer puzzle and vastly advances our functional as well as evolutionary insight into the process of endocytosis.

Word-order change in progress: the case of Slovene and Serbo-Croat and its relevance for Germanic

It will be suggested in this article that Slovene, a South Slavonic language, is on the way to acquiring verb-second (V2) word order. In providing evidence in support of this view I shall compare Slovene, on the one hand, with the closely related language Serbo-Croat and, on the other hand, with relevant details from the history of the Germanic languages. The point of comparing it with Serbo-Croat is to discover the respects in which the word order of these two languages has diverged. Taken together with what is known about the word order of Common Slavonic, the facts emerging from this comparison allow us to identify one major respect in which Slovene has changed and two respects in which it is still changing. At the same time, they reveal a major respect in which Serbo-Croat word order is also changing. The point of comparing Slovene with the Germanic languages is twofold. First, since all the present-day Germanic languages either have or have had V2 word order (Haiman, 1974), it is possible that their history can help us to understand the changes currently taking place in Slovene and to predict how Slovene might change in the future. Secondly, where details of the history of the Germanic languages are poorly understood, the possibility exists of gaining fresh insight into them in the light of the changes that have taken place more recently, or indeed are still taking place, in Slovene. In this connection we shall assess the plausibility of two theories concerning the adoption of V2 word order by the Germanic languages, those of Vennemann (1975) and Wackernagel (1892).

AbstractBiological cilia generate fluid movement within viscosity-dominated environments using beating motions that break time-reversal symmetry. This creates a metachronal wave, which enhances flow efficiency. Artificially mimicking this behaviour could improve microfluidic point-of-care devices, since viscosity-dominated fluid dynamics impede fluid flow and mixing of reagents, limiting potential for multiplexing diagnostic tests. However, current biomimicry schemes require either variation in the hydrodynamic response across a cilia array or a complex magnetic anisotropy configuration to synchronise the actuation sequence with the driving field. Here, we show that simple modifications to the structural design introduce phase differences between individual actuators, leading to the spontaneous formation of metachronal waves. This generates flow speeds of up to 16 μm/s as far as 675 μm above the actuator plane. By introducing metachronal waves through lithographic structuring, large scale manufacture becomes feasible. Additionally, by demonstrating that metachronal waves emerge from non-uniformity in internal structural mechanics, we offer fresh insight into the mechanics of cilia coordination.

AbstractA laser based non-destructive technique has been used to study the morphology of sputterdeposited aluminum alloy films. The data emanating from the Therma-wave Imager that makes use of this principle, has been correlated with reflectivity, grain size and micro-roughness of the film. In addition, through the use of a case study, this paper demonstrates the utility of this application as an in-line monitor in an integrated circuit fabrication line.

<p>Carbonyl sulfide (OCS) is the most abundant sulfur containing gas in the atmosphere and is an important source of stratospheric aerosol. Furthermore, it has been shown that OCS can be used as a proxy for photosynthesis, which is a powerful tool in quantifying global gross primary production. While considerable improvements have been made in our understanding of the location and magnitude of OCS fluxes over the past few decades, recent studies highlight the need for a new satellite dataset to help reduce the uncertainties in current estimations. The Infrared Atmospheric Sounding Interferometer (IASI) instruments on-board the MetOp satellites offer over 14 years of nadir viewing radiance measurements with excellent spatial coverage. Given that there are currently three IASI instruments in operation, there is the potential for a significantly larger OCS dataset than is currently available elsewhere. Retrievals of OCS from these IASI radiances have been made using an adapted version of the University of Leicester IASI Retrieval Scheme (ULIRS). OCS total column amounts are calculated from profiles retrieved on a 31-layer equidistant pressure grid, using an optimal estimation approach for microwindows in the range 2000 – 2100 cm<sup>-1</sup> wavenumbers. Sensitivity of the measurements peak in the mid-troposphere, between 5 – 10 km.</p><p>The outlook of this work is to produce a long-term OCS satellite observational data set that provides fresh insight to the spatial distribution and trend of atmospheric OCS. Here, we present subsets of data in the form of case studies for different geographic regions and time periods.</p>

Purpose The purpose of this paper is to critically analyse the correlation between the rule of law and the efficient functioning of capital markets. It attempts to examine the Nigerian capital market and how the rule of law can be used to prevent fraud and promote the proper functioning of the market. Design/methodology/approach The paper adopts the doctrinal approach through a critical evaluation of concepts. Using existing literature in the subject area, it evaluates the inter-connectedness between law and the capital market and how the rule of law is an important instrument in capital market development. Findings The paper finds that there have been numerous infractions of the rule of law by capital market actors, leading to stultification in the growth and development of this sector of the Nigerian economy. Originality/value The paper offers a fresh insight into the correlation between the rule of law and capital markets. By critically assessing the inter-connectivity between the two concepts, it extends the body of knowledge in this area by showing how the operations of the Nigerian capital market could be improved through the proper application of the rule of law.
