Introduction: The term “bioceramic” is used in endodontics to describe various products and is often used in general terms for mineral trioxide aggregate (MTA) and other hydroscopic dental cements (HDC), which creates confusion in the terminology. Aim: The aim of the study is to present a definition and an original classification of bioceramic endodontic sealers. Materials and methods: A total of 123 articles were found by the PubMed search engine using the key phrase “bioceramic endodontic sealers”. Of these 123 articles, we analyzed 20 articles that contain information about the composition, properties, definition, and classification of bioceramic endodontic sealers. Results: In accordance with the collected data on the composition and the delivery form of calcium silicate endodontic sealers, we propose a new definition of bioceramic endodontic sealers that clarifies the specificities of these materials. In the new classification they are divided by two criteria: source of calcium silicate and form of delivery. It also contains the particular products’ names in order to aid their usage in the clinical practice.  Conclusions: The new definition of bioceramic endodontic sealers clears out the confusion in the terminology, which promotes the classification of these products and helps understanding their clinical application.

Quantitative Indicators

The need to identify wood by its anatomical features requires a detailed analysis of all the elements that make it up. This is a significant problem of structural wood science, the most general and complete solution of which is yet to be sought. In recent years, increasing attention has been paid to the use of computer vision methods to automate processes such as the detection, identification, and classification of different tissues and different tree species. The more successful use of these methods in wood anatomy requires a more precise and comprehensive definition of the anatomical elements, according to their geometric and topological characteristics. In this article, we conduct a detailed analysis of the limits of variation of the location and grouping of vessels in the observed microscopic samples. The present development offers criteria and quantitative indicators for defining the terms shape, location, and group of wood tissues. It is proposed to differentiate the quantitative indicators of the vessels depending on their geometric and topological characteristics. Thus, with the help of computer vision technics, it will be possible to establish topological characteristics of wood vessels, the extraction of which would be used to develop an algorithm for the automatic classification of tree species.

Cognitive Meaning

The article provides a new classification of evaluative concepts enshrined in the Criminal Code of the Russian Federation, indicates the purpose of its existence in the doctrine of criminal law. The article describes the definition of constitutive evaluative concepts that are determined as legislatively vague evaluative concepts that, by their normative-essential and functionally-substantive characteristics, are absolute, necessarily alternative, or accompanying structural features of a crime. Through the prism of the features of constitutive evaluative concepts, their varieties, essential features and functions are distinguished; interpretation (including cognitive) meaning is revealed. Moreover, the interpretation features of these evaluative concepts are considered in two interdependent aspects: the structurally-essential (associated with the types, attributes and functions of constitutive evaluative concepts) and the procedural-substantive (associated with the informative and informative activities of the interpreter). It is indicated that the interpretation features of an structurally-essential nature are, firstly, in the composition and criminogenic properties of constitutive evaluative concepts, and secondly, in the semantic structural composition, indicating a meaningful dependence of the evaluative concept on the accompanying structural features of a crime, and thirdly, legally significant functional features. At the same time, interpretative features of a procedural-substantive order are also highlighted, which include, firstly, the need for a paramount definition of the criminogenic determinant, designed to establish the structural features of a crime in a perfect act, and secondly, in an increased degree of normative casuistic derivative of these evaluative concepts. The author comes to the conclusion that constitutive evaluative concepts are interpreted according to the same logical-linguistic and legal laws, but with some marked structurally meaningful features.

Definition Of

Kambin’s triangle is an anatomical corridor used to access critical structures in a variety of spinal procedures. It is considered a safe space because it is devoid of vascular and neural structures of importance. Nonetheless, there is currently significant variation in the literature regarding the exact dimensions and anatomical borders of Kambin’s triangle. This confusion was originally caused by leaving the superior articular process (SAP) unassigned in the description of the working triangle, despite Kambin identifying that structure in his original report. The SAP is the most relevant structure to consider when accessing the transforaminal corridor. Leaving the SAP unassigned has led to an open-handed application of the term “Kambin’s triangle.” That single eponym currently has two potential meanings, one meaning for endoscopic surgeons working through a corridor in the intact spine and a second meaning for surgeons accessing the disc space after a complete or partial facetectomy. Nevertheless, an anatomical corridor should have one consistent definition to clearly communicate techniques and use of instrumentation performed through that space. As such, the authors propose a new surgically relevant classification of this corridor. Assigning the SAP a border requires adding another dimension to the triangle, thereby transforming it into a prism. The term “Kambin’s prism” indicates the assignment of a border to all relevant anatomical structures, allowing for a uniform definition of the 3D space. From there, the classification scheme considers the expansion of the corridor and the extent of bone removal, with a particular focus on the SAP.

Original Classification

Classically, the accessory nerve is described as having a cranial and a spinal root. Textbooks are inconsistent with regard to the modality of the spinal root of the accessory nerve. Some authors report the spinal root as general somatic efferent (GSE), while others list a special visceral efferent (SVE) modality. We investigated the comparative, anatomical, embryological, and molecular literature to determine which modality of the accessory nerve was accurate and why a discrepancy exists. We traced the origin of the incongruity to the writings of early comparative anatomists who believed the accessory nerve was either branchial or somatic depending on the origin of its target musculature. Both theories were supported entirely by empirical observations of anatomical and embryological dissections. We find ample evidence including very recent molecular experiments to show the cranial and spinal root are separate entities. Furthermore, we determined the modality of the spinal root is neither GSE or SVE, but a unique peripheral nerve with a distinct modality. We propose a new classification of the accessory nerve as a transitional nerve, which demonstrates characteristics of both spinal and cranial nerves.

Present Understanding

Some intra-cratonic basins are traditionally called ?aulacogens?. This term has persisted in the geoscience literature since its invention by Soviet geologists in the mid-20th century before the triumph of the plate tectonics, but its meaning has evolved. Attempts to change its meaning from descriptive to genetic have led to a broad spectrum of opinions on the definition of aulacogens. Some specialists related them to continental rifts, while others have restricted aulacogens to the only particular rift systems or peculiar stages in the evolution of young cratons. The Donets Basin is a typical aulacogen stretching across the southern margin of the East European Craton. A brief review of present knowledge of this basin shows that its nature is rather incompatible with the present understanding of aulacogens. Instead, the new classification of rifts offers a more precise terminology for its exact characteristics. It is suggested that the term ?aulacogen? should only be restricted to those basins for which it has been applied historically.

At the present time, the common classification of geophysical maps is missing, which is a consequence of their long-term development of the geological mapping. The features of existing approaches to the definition of geophysical maps’ place among maps of natural phenomena and the limitations of existing lists of mapping themes were determined and identified in this article. New approaches to the classification of geophysical maps that take into account the completeness of their contents and the current state of geophysical mapping were offered. A new classification of geophysical maps was elaborated based on four criteria

Woolly Mammoth

De-extinction projects for species such as the woolly mammoth and passenger pigeon have greatly stimulated public and scientific interest, producing a large body of literature and much debate. To date, there has been little consistency in descriptions of de-extinction technologies and purposes. In 2016, a special committee of the International Union for the Conservation of Nature (IUCN) published a set of guidelines for de-extinction practice, establishing the first detailed description of de-extinction; yet incoherencies in published literature persist. There are even several problems with the IUCN definition. Here I present a comprehensive definition of de-extinction practice and rationale that expounds and reconciles the biological and ecological inconsistencies in the IUCN definition. This new definition brings together the practices of reintroduction and ecological replacement with de-extinction efforts that employ breeding strategies to recover unique extinct phenotypes into a single “de-extinction” discipline. An accurate understanding of de-extinction and biotechnology segregates the restoration of certain species into a new classification of endangerment, removing them from the purview of de-extinction and into the arena of species’ recovery. I term these species as “evolutionarily torpid species”; a term to apply to species falsely considered extinct, which in fact persist in the form of cryopreserved tissues and cultured cells. For the first time in published literature, all currently active de-extinction breeding programs are reviewed and their progress presented. Lastly, I review and scrutinize various topics pertaining to de-extinction in light of the growing body of peer-reviewed literature published since de-extinction breeding programs gained public attention in 2013.

Existing Data

Deficiencies in the Hutchinson–Löffler classification of lakes based on mixing are reviewed and organized under the following headings: (1) exclusion of shallow lakes, (2) unsatisfactory relationship between meromixis and the six basic lake types, (3) excessively complex treatment of tropical lakes, and (4) difficulties in classification of cold lakes due to the 4 °C boundary on cold monomixis. A revision remedies these deficiencies with minimal changes in terminology and conceptual foundation of the original classification. The revision incorporates the following features: (1) the meromixis/holomixis dichotomy is combined with the six lake types based on seasonal mixing in such a way that the two systems are hierarchical and universal; meromictic lakes are assigned to a seasonal type on the basis of the behavior of the upper water column, (2) oligomixis is eliminated, (3) shallow lakes are brought under the classification by definition of four polymictic types based on ice cover and frequency of mixing. Dependence of the eight mixing types of the revised classification on latitude, elevation, and depth is estimated from existing data, and examples are given of each type.
