Communication Pathway

As the connection at the proximal tip plays an important role for sensing guidewires, we compared various sensing guidewires with regard to their proximal connectors. The strengths and weaknesses of each are discussed and recommendations for future development are provided. A literature search limited to the English language for the time period from the 1960s to the 2010s has been performed on the USPTO database, Espacenet, and Web of Science. The results have been categorized on the basis of the connector design. A comprehensive overview and classification of proximal connectors for sensing guidewires used for cardiovascular interventions is presented. The classification is based on both the type of connector (fixed or removable) and the type of connection (physical, wireless, or a combination). Considering the complexity of the currently prototyped and tested connectors, future connector development will necessitate an easy and cost-effective manufacturing process that can ensure safe and robust connections.

✓In this historical perspective, the author identifies three epochs in the development of the concepts and treatment of spinal vascular lesions: 1) early observations (1860s–1912), with the lesions during this time period recognized only at autopsy; 2) the “middle ages” (1912–1960), with surgical intervention sporadic and yielding dismal results; and 3) the modern era (beginning in the 1960s), coincident with parallel dramatic advances in radiology, microsurgical instrumentation, and anesthesiology. These advances resulted in a better understanding of the pathophysiological aspects and angioarchitecture of the lesions. Whereas the nomenclature of the lesions in the past was confusing, a new understanding of these diseases that has emerged during the modern era has permitted refinement of the classification of the lesions as distinct biological entities. Modern diagnostic imaging has enabled identification of patients who may benefit from surgical or embolic occlusion, and treatment has become rationally based. Future progress in the management of spinal vascular lesions may be anticipated, with improvement in noninvasive imaging for early detection of suspected abnormalities. Furthermore, advances in spinal cord neuroprotection may expand the range of future options for surgical or embolic intervention.

Light Interference

In an office space, an LED-based lighting system allows you to perform the function of a data transmitter. This article discusses the cost-effective design and development of a data-enabled LED driver that can transmit data along with its receiving part. In addition, this paper clearly outlines the application of the proposed VLC system in an office environment where ambient light interference is a severe issue of concern. The result shows satisfactory lighting characteristics in general for this area in terms of average horizontal illuminance and illuminance uniformity. At the same time, to evaluate real-time and static communication performance, Arduino interfaced MATLAB Simulink model is developed, which shows good communication performance in terms of BER (10–7) even in presence of ambient light noise with 6 dB signal to interference plus noise ratio. Our designed system is also flexible to work as a standalone lighting system, whenever data communication is not required.

In the last decade, an array of smartphone apps have been designed to prevent crime, violence, and abuse. The evidence base of these apps has, however, yet to analyzed systematically. To rectify this, the aims of this review were (1) to establish the extent, range, and nature of research into smartphone apps with a primary crime prevention function; (2) to locate gaps in the primary crime prevention app literature; and (3) to develop a typology of primary crime prevention apps. Employing a scoping review methodology and following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, studies were identified via Web of Science, EBSCOhost, and Google Scholar. We included English-language research published between 2008 and 2020 that examined smartphone applications designed explicitly for primary crime prevention. Sixty-one publications met our criteria for review, out of an initial sample of 151 identified. Our review identified six types of crime prevention app examined in these publications: self-surveillance apps, decision aid apps, child-tracking apps, educational apps, crime-mapping/alert apps, and crime reporting apps. The findings of our review indicate that most of these forms of primary crime prevention apps have yet to be rigorously evaluated and many are not evidence-based in their design. Consequently, our review indicates that recent enthusiasm over primary crime prevention apps is not supported by an adequate evidence base.

Estimation Models

Ship collisions are one of the most common types of maritime accidents. Assessing the frequency and probability of ship collisions is of great importance as it provides a cost-effective and practical way to mitigate risk. In this paper, we present a review of quantitative ship collision frequency estimation models for waterway risk assessment, accompanied by a classification of the models and a description of their main modelling characteristics. Models addressing the macroscopic perspective in the estimation of ship collision frequency on waterways are reviewed in this paper with a total of 29 models. We extend the existing classification methodology and group the collected models accordingly. Special attention is given to the criteria used to detect potential ship collision candidates, as well as to causation probability and the correlation of models with real ship collision statistics. Limitations of the existing models and future improvement possibilities are discussed. The paper can be used as a guide to understanding current achievements in this field.

AbstractLarge slow rock-slope deformations, including deep-seated gravitational slope deformations and large landslides, are widespread in alpine environments. They develop over thousands of years by progressive failure, resulting in slow movements that impact infrastructures and can eventually evolve into catastrophic rockslides. A robust characterization of their style of activity is thus required in a risk management perspective. We combine an original inventory of slow rock-slope deformations with different PS-InSAR and SqueeSAR datasets to develop a novel, semi-automated approach to characterize and classify 208 slow rock-slope deformations in Lombardia (Italian Central Alps) based on their displacement rate, kinematics, heterogeneity and morphometric expression. Through a peak analysis of displacement rate distributions, we characterize the segmentation of mapped landslides and highlight the occurrence of nested sectors with differential activity and displacement rates. Combining 2D decomposition of InSAR velocity vectors and machine learning classification, we develop an automatic approach to characterize the kinematics of each landslide. Then, we sequentially combine principal component and K-medoids cluster analyses to identify groups of slow rock-slope deformations with consistent styles of activity. Our methodology is readily applicable to different landslide datasets and provides an objective and cost-effective support to land planning and the prioritization of local-scale studies aimed at granting safety and infrastructure integrity.

Grassland remote sensing (GRS) is an important research topic that applies remote sensing technology to grassland ecosystems, reflects the number of grassland resources and grassland health promptly, and provides inversion information used in sustainable development management. A scientometrics analysis based on Science Citation Index-Expanded (SCI-E) was performed to understand the research trends and areas of focus in GRS research studies. A total of 2692 papers related to GRS research studies and 82,208 references published from 1980 to 2020 were selected as the research objects. A comprehensive overview of the field based on the annual documents, research areas, institutions, influential journals, core authors, and temporal trends in keywords were presented in this study. The results showed that the annual number of documents increased exponentially, and more than 100 papers were published each year since 2010. Remote sensing, environmental sciences, and ecology were the most popular Web of Science research areas. The journal Remote Sensing was one of the most popular for researchers to publish documents and shows high development and publishing potential in GRS research studies. The institution with the greatest research documents and most citations was the Chinese Academy of Sciences. Guo X.L., Hill M.J., and Zhang L. were the most productive authors across the 40-year study period in terms of the number of articles published. Seven clusters of research areas were identified that generated contributions to this topic by keyword co-occurrence analysis. We also detected 17 main future directions of GRS research studies by document co-citation analysis. Emerging or underutilized methodologies and technologies, such as unmanned aerial systems (UASs), cloud computing, and deep learning, will continue to further enhance GRS research in the process of achieving sustainable development goals. These results can help related researchers better understand the past and future of GRS research studies.

AbstractChinese and Western archaeologists (especially those of the anthropologically-oriented tradition) often seem to be talking past each other, not only because they are publishing in different languages, but also because of differences in theory and method. While most of the major theoretical works in Western languages are by now available in Chinese translations, hardly any English-language publications exist that explain Chinese approaches to archaeological method and theory. This article helps to bridge the gap by introducing the history of debates on archaeological method in China to a Western audience, focusing particularly on issues of typology and classification. Discussing in detail the merits—and issues—of approaches suggested by four of the most influential Chinese archaeologists (Li Chi, Xia Nai, Su Bingqi, and K. C. Chang), this article provides a deeper understanding of the preconditions of archaeological research in China. It also suggests future directions for archaeological work by local and foreign archaeologists, including but also going beyond the classification of the rich body of artifacts coming to light in Chinese excavations.

Abstract The first part of this paper considers approaches to teacher education for EFL developed during the 1960s-1990s, drawing upon two sources: the taxonomy of three approaches proposed by Wallace (1991) and personal reminiscence. It discusses each of Wallace's approaches in turn: craft, 'applied science', and reflective practice.The second part considers whether these approaches are adequate models for teacher education now. I suggest that while they are still relevant, they are also too inward looking for contemporary needs.They need to be supplemented with a more outward looking approach, in which teachers are prepared to engage with four aspects of the contemporary context: new communication technologies, the new global linguistic landscape, the relationship between English and learners' own languages, and the rival political views of English language learning as promoting either a global neoliberal agenda or a global civil society.

The classification of Russian culture-bound terms used in the novel “Quiet Flows the Don” by M. A. Sholokhov and in its translation into the English language. The novel “Quiet Flows the Don” by M.A. Sholokhov and its translation into English done by Robert Daglish have served as the source for the research of culture-bound terms. These terms have been classified on the basis of the subject division offered by S. Vlakhov and S. Florin. It is proved that the interest to the study of culture-bound terms is still important. The relevance of the research is determined by the fact that despite numerous research papers in this field the origin, classification and translation of these terms still need some investigation. The aim of the present study is to classify the culture-bound terms taken from the novel “Quiet Flows the Don” by M.A. Sholokhon and its translation into the English language. As a result, there have bben taken 407 samples of the lexical units with a cultural component which were classified according to the subject principal offered by S. Vlakhon and S. Florin. The culture-bound terms have a great influence on a foreign reader as they are cultural units that transmit the information of the daily routine and the historical epoch described in the novel. The culture-bound terms taken from the novel “Quiet Flows the Don” by M.A. Sholokhov and its translation are analyzed and classified. The division of the culture-bound terms according to the subject principal allowed to reveal that most terms refer to the daily routine, social and political life and military terms.

AbstractBackground:Myotonic dystrophy types 1 and 2 are progressive multisystem genetic disorders, whose core clinical feature is myotonia. Mexiletine, an antagonist of voltage-gated sodium channels, is a recommended anti-myotonic agent in the non-dystrophic myotonias, but its use in myotonic dystrophy is limited due to lack of data regarding its long-term efficacy and safety profile.Methods:To address this issue, this study retrospectively evaluated patients with myotonic dystrophy receiving mexiletine over a mean time-period of 32.9 months (range 0.1 to 216 months).Results:This study demonstrated that 96% of patients reported some improvement in myotonia symptoms with mexiletine treatment. No clinically relevant cardiac adverse events were associated with the long-term use of mexiletine.Conclusions:These findings support that mexiletine is both safe and effective when used long-term in myotonic dystrophy.Classification of Evidence:This study provides class IV evidence that mexiletine is a well-tolerated and effective treatment for myotonic dystrophy types 1 and 2.
