This paper tests the new-dialect formation model of Peter Trudgill (1986 et seq) by examining several phonological features of Tibetan as spoken in the diaspora community of Kathmandu, Nepal. Established by an influx of migrants from many dialect regions beginning in 1959, this presents a unique opportunity to study koinéization, new dialect formation, in progress. Trudgill’s model predicts that a new dialect should largely emerge in the second generation born in the new region, exhibiting both simplification, the failure of marked variants to transmit across generations, and focusing, the selection of particular variants as a new norm for the community's new variety.Data from seventy-three sociolinguistic interviews was coded for phonological and lexical variables known to differ across Tibetan-speaking regions, and NeighborNets were constructed in SplitsTree. Results indicate that regionally marked variables were not transmitted into the first or second generation of Diaspora-raised speakers, but Diaspora speakers exhibited a high degree of variation comparable to that of speakers from the numerically- and socially-dominant U-Tsang region. That younger speakers have not yet converged on a single new variety suggests a role for additional factors to affect the rate of koinéization.

The entire character recognition system is logically characterized into different sections like Scanning, Pre-processing, Classification, Processing, and Post-processing. In the targeted system, the scanned image is first passed through pre-processing modules then feature extraction, classification in order to achieve a high recognition rate. This paper describes mainly on Feature extraction and Classification technique. These are the methodologies which play an important role to identify offline handwritten characters specifically in Gujarati language. Feature extraction provides methods with the help of which characters can identify uniquely and with high degree of accuracy. Feature extraction helps to find the shape contained in the pattern. Several techniques are available for feature extraction and classification, however the selection of an appropriate technique based on its input decides the degree of accuracy of recognition.

Various agencies have begun to research and introduce performance-related specifications (PRS) for the design of modern asphalt paving mixtures. The focus of most recent studies has been directed toward simplified cracking test development and evaluation. In some cases, development and validation of PRS has been performed, building on these new tests, often by comparison of test values to accelerated pavement test studies and/or to limited field data. This study describes the findings of a comprehensive research project conducted at Illinois Tollway, leading to a PRS for the design of mainline and shoulder asphalt mixtures. A novel approach was developed, involving the systematic establishment of specification requirements based on: 1) selection of baseline values based on minimally acceptable field performance thresholds; 2) elevation of thresholds to account for differences between short-term lab aging and expected long-term field aging; 3) further elevation of thresholds to account for variability in lab testing, plus variability in the testing of field cores; and 4) final adjustment and rounding of thresholds based on a consensus process. After a thorough evaluation of different candidate cracking tests in the course of the project, the Disk-shaped Compact Tension—DC(T)—test was chosen to be retained in the Illinois Tollway PRS and to be presented in this study for the design of crack-resistant mixtures. The DC(T) test was selected because of its high degree of correlation with field results and its excellent repeatability. Tailored Hamburg rut depth and stripping inflection point thresholds were also established for mainline and shoulder mixes.

Cyber threats have been growing tremendously in recent years. There are significant advancements in the threat space that have led towards an essential need for the strengthening of digital infrastructure security. Better security can be achieved by fine-tuning system parameters to the best and optimized security levels. For the protection of infrastructure and information systems, several guidelines have been provided by well-known organizations in the form of cybersecurity standards. Since security vulnerabilities incur a very high degree of financial, reputational, informational, and organizational security compromise, it is imperative that a baseline for standard compliance be established. The selection of security standards and extracting requirements from those standards in an organizational context is a tedious task. This article presents a detailed literature review, a comprehensive analysis of various cybersecurity standards, and statistics of cyber-attacks related to operating systems (OS). In addition to that, an explicit comparison between the frameworks, tools, and software available for OS compliance testing is provided. An in-depth analysis of the most common software solutions ensuring compliance with certain cybersecurity standards is also presented. Finally, based on the cybersecurity standards under consideration, a comprehensive set of minimum requirements is proposed for OS hardening and a few open research challenges are discussed.

AbstractIn Nova Scotia one leaf cluster with an adjoining 1 inch of twig taken from the inside of each of 10 apple trees replicated four times is an adequate sample unit to measure the density of the brown mite.The brown mite has one generation with a partial second in some orchards and one with a partial second and partial third in others. The first generation adults in the bivoltine and trivoltine populations lay summer eggs on the leaves and twigs, and diapause eggs on tin twigs. The second generation adults in the bivoltine populations lay only diapause eggs; in the trivoltine populations they lay both summer and diapause eggs. The adults of the third generation lay only diapause eggs.The brown mite is found on both the leaves and woody parts of the tree. In orchards with bivoltine populations the proportion of mites on leaves reached a peak of 80% by mid-July, but thereafter gradually decreased to 10% by the end of August. However, in orchards with trivoltine populations the proportion of mites on leaves reached a peak of 80 to 90% by mid-July, remained constant until mid-August, and thereafter decreased to approximately 40% by the end of August.The number of diapause eggs laid by adults of each generation in both the bivoltine and trivoltine populations varies widely. The eggs are deposited on the trunk as well as on the branches, with the heaviest deposition in the central area of the tree. The diapause eggs laid by adults of the first generation are the last to hatch and those laid by the third generation are the first to hatch the following spring.The factors responsible for the differences in the number of generations and in the number of diapause eggs laid are unknown.

In vitro sensitivities of 70 shigella strains isolated over a recent 18-month period are reported. The high degree of sulfadiazine resistance casts some doubt on the selection of this agent as the drug of choice in the treatment of shigellosis, at least in this community. Some of the other agents, although inhibiting the growth of the organisms in vitro, have disadvantages such as toxicity or failure of absorption from the gastrointestinal tract. Tetracycline resistance was found in only 7% of the organisms tested, but from this and other reports we may anticipate the occurrence of more organisms resistant to this agent. The results of the sensitivities to ampicillin are encouraging and further studies including clinical trials of this agent are in order.

Abstract This study examines the ability to identify different Chinese dialects through the English language and evaluates how often respondents pay attention to phonological features and rate of speech to explain their categorizations. The research includes 100 Chinese undergraduate students and 100 young people without advanced degrees aged 20 to 25. Discrete independent data samples collected during the interview of participants are analyzed with the help of such statistical methods as Student's t-test, Mann-Whitney U-test, and Wilcoxon's test. The obtained results indirectly show the ability of respondents to identify native and non-native English speakers around the world, as well as determine their nationality. The outcomes of the paper explicate who, in general, categorize Chinese dialects better and which dialects are the most recognizable. Research data reveal a high degree of stereotypization of various dialects, especially the Beijing and U dialects. Moreover, based on the data obtained, it can be concluded that speaking rate significantly affects the perception and classification of a speaker from a particular province of China.

One of the fundamental tasks in restoring the operability of cylinder liners is the application of a composite coating with a predetermined microhardness value. The authors have developed a technology for applying composite coatings based on iron on cylindrical surfaces, which makes it possible to vary the physical, mechanical and operational parameters of the formed iron-containing coating due to the planned selection of the deposition parameters. This eliminates the need for mechanical treatment of the applied coating, which is the reason for the high degree of rejection parts that undergo the iron-on operation. Contact interaction of the working tool with the formed layer of the composite coating has a positive effect on the value of its roughness.

Abstract. Rice can form not only white, but also red, brown and black grains. In black rice, pericarp grains contain anthocyanins, which have antioxidant activity and are beneficial to human health. The purpose of the work is to study the inheritance of the black color of the pericarp and other qualitative traits in the intersubspecific hybrid of rice Kuboyar × Gagat, the selection of the best recombinant forms combining early ripeness, a compact erect panicle and black grain, the creation of the source material for practical selection. Methods The studies were carried out on hybrids of the first and second generation from crossing a white-grain variety of rice Kuboyar with black-grained Gagat in 2018–2019 in the Separate Division “Proletarskoye” of the Rostov Region. Results. A genetic analysis of the inheritance of the duration of the growing season, qualitative signs of coloring of flower scales and rice grains, and spinousness was carried out. In the second generation, 54 photosensitive non-flowering plants and 128 normal ones broke out, which indicates the interaction of four dominant genes in the genotype. The splitting according to the color of the pericarp was carried out according to the trihybrid scheme according to the type of com-plementarity in the ratio of 27 black: 21 brown: 16 white. The black color of the pericarp was formed when three dominant genes Kala1, 3, and 4 were present in the genotype, brown was determined by the Kala4 gene, and white by the remaining combinations of genes. According to the color of flowering scales, the cleavage occurred according to the digrid pattern: 9 black: 3 yellow with black apiculus: 4 straw yellow. Although the parental varieties were boneless, 39 spinous forms appeared in F2 with three complementary dominant genes An-a, An-b, An-c and inhibitor I, the remaining 89 plants were boneless. The best recombinant forms were selected, combining the optimal values of plants and panicles and black grain, the source material for practical selection was created.
