COVID-19 in dentistry and dental education
Dentistry has already been shown to be a hazardous occupation due to the numerous infectious and health risks associated with it. Over the past year and a half, this risk has only grown because of the highly transmissible nature of the Coronavirus. Dentistry, being a profession where the operator and the assistants are in close contact with the patients, has seen numerous changes. Not only this, but even dental education has been impacted as most of the teaching over the pandemic period has been conducted online. Furthermore, dental education has been highly impacted as a major part of it involves hands-on training. Due to this, there are several social, financial, and health-related repercussions that must be analyzed and understood. This Special Issue invited manuscripts, both research and review, that analyze the SARS-CoV-2 situation with regard to dentistry and dental education.
Control of Turbulent and Magnetohydrodynamic Channel Flows : Boundary Stabilization and State Estimation
This monograph presents new constructive design methods for boundary stabilization and boundary estimation for several classes of benchmark problems in flow control, with potential applications to turbulence control, weather forecasting, and plasma control. The basis of the approach used in the work is the recently developed continuous backstepping method for parabolic partial differential equations, expanding the applicability of boundary controllers for flow systems from low Reynolds numbers to high Reynolds number conditions. Efforts in flow control over the last few years have led to a wide range of developments in many different directions, but most implementable developments thus far have been obtained using discretized versions of the plant models and finite-dimensional control techniques. In contrast, the design methods examined in this book are based on the “continuum” version of the backstepping approach, applied to the PDE model of the flow.

These include historical, narrative, literary, phenomenological, autobiographical, virtual and performance texts, among others. Qualitative Research in Postmodern Times is an exciting and accessible book that will be essential reading for science, mathematics and technology educators interested in new forms of educational research. Beginning researchers will find it practically helpful in planning and conducting their research studies, while experienced researchers will welcome new theoretical insights into postmodern methodologies.
Conducting Quantitative Research In Education
provides a clear and straightforward guide for all those seeking to conduct quantitative research in the field of education, using primary research data samples. While positioned as less powerful and somehow inferior, non-parametric tests can be very useful where the research can only be designed to accommodate data structure which is ordinal, or scale but violates a normality assumption, which is required for parametric tests. Non-parametric data are a staple of educational research, and as such, it is essential that educational researchers learn how to work with these data with confidence and rigour.
Conducting Polymers with Micro or Nanometer Structure

Heeger, University of California at Santa Barbara, Alan G. MacDiarmid at the University of Pennsylvania, and Hideki Shirakawa at the University of Tsukuba. Since then, the unique properties of conducting polymers have led to promising applications in functional materials and technologies. The book first briefly summarizes the main concepts of conducting polymers before introducing micro/nanostructured conducting polymers dealing with their synthesis, structural characterizations, formation mechanisms, physical and chemical properties, and potential applications in nanomaterials and nanotechnology. The book is intended for researchers in the related fields of chemistry, physics, materials, nanomaterials and nanodevices.

Computer Network Security ; Vol. 3685
This volume contains papers presented at the 3rd International Workshop on Mathematical Methods, Models and Architectures for Computer Network - curity (MMM-ACNS 2005) held in St. Petersburg, Russia, 2005. The 1st and the 2nd International Workshops on Mathematical Methods, Models and Architectures for Computer Network Security (MMM-ACNS 2001 and MMM-ACNS 2003), hosted by the St. Petersburg Institute for Informatics and Automation, demonstrated the keen interest of the international research community in the subject area. It was recognized that conducting a biannual series of such workshops in St. Petersburg stimulates fruitful exchanges between the di?erent schools of thought, facilitates the dissemination of new ideas and promotesthespirit of cooperationbetweenresearchersontheinternationalscale. MMM-ACNS 2005 provided an international forum for sharing original - search results and application experiences among specialists in fundamental and applied problems of computer network security. An important distinction of the workshop was its focus on mathematical aspects of information and computer network security addressing the ever-increasing demands for secure computing and highly dependable computer networks.

Computational Materials Chemistry : Methods and Applications
As a result of the advancements in algorithms and the huge increase in speed of computers over the past decade, electronic structure calculations have evolved into a valuable tool for characterizing surface species and for elucidating the pathways for their formation and reactivity. It is also now possible to calculate, including electric field effects, STM images for surface structures. To date the calculation of such images has been dominated by density functional methods, primarily because the computational cost of - curate wave-function based calculations using either realistic cluster or slab models would be prohibitive. DFT calculations have proven especially valuable for elucidating chemical processes on silicon and other semiconductor surfaces. However, it is also clear that some of the systems to which DFT methods have been applied have large non-dynamical correlation effects, which may not be properly handled by the current generation of Kohn-Sham-based density functionals. For example, our CASSCF calculations on the Si(001)/acetylene system reveal that at some geometries there is extensive 86 configuration mixing. This, in turn, could signal problems for DFT cal- lations on these systems.
Computational logic in multi-agent systems ; Vol. 3487 ; 5th International Workshop, CLIMA V, Lisbon, Portugal, September 29-30, 2004, Revised Selected and Invited Papers
The notion of agency has recently increased its in?uence in the research and - velopment of computational logic based systems, while at the same time sign- cantly gaining from decades of research in computational logic. Computational logic provides a well-de?ned, general, and rigorous framework for studying s- tax, semantics and procedures, for implementations, environments, tools, and standards, facilitating the ever important link between speci?cation and ver- cation of computational systems. The purpose of the Computational Logic in Multi-agent Systems (CLIMA) international workshop series is to discuss techniques, based on computational logic, for representing, programming, and reasoning about multi-agent systems in a formal way. Former CLIMA editions were conducted in conjunction with other major computational logic and AI events Thesubmittedpapersshowedthatthelogicalfoundationsofmulti-agent systems are felt by a large community to be a very important research topic, upon which classical AI and agent-related issues are to be addressed.
