Representations of the Hecke Group G(2) from Fermionic Modular Categories

This project explores a conjecture which states that groups from the Fermionic Modular Category are finite; specifically representations of the Hecke group G(2) will be explored which are important in number theory. These representations are used for a mathematical model of Topological Quantum Computation (TQC) based on topological symmetries rather than geometric symmetries. The use of topological symmetries reduces the effects of outside interference on computations due to the nature of topological symmetries relying on the general shape instead of particular distances or angles. TQC would aid in the development of quantum computing by helping to solve the problem of interference in quantum particles. Magma algebraic software was used in order to generate these group representations and provide information on their resulting structure to aid in identification

Taking the Initiative in Problem-Solving Discourse

Human participants in a conversation display a flexibility in shifting initiative not currently found 10 natural language processing systems. They frequently take charge of the dialogue to provide necessary, but unrequested Information Based on an analysis of transcripts of student advising dialogues, we present a. theory of role shifting that details the information needed to take the initiative, motivations for doing so, and expectations arising from the current discourse state motivations for taking the Initiative may arise either from the domain task or from the communication requirements of the dialogue itself. To maintain conversational coherence while taking the initiative a system must consider the expectations arising from the current topic and role states. We present data to support our conclusions which have implications for natural language computer systems

Limitation of Trypanosoma brucei parasitaemia results from a combination of density-dependent parasite differentiation and parasite killing by the host immune response

In the bloodstream of its mammalian host, the "slender" form of Trypanosoma brucei replicates extracellularly, producing a parasitaemia. At high density, the level of parasitaemia is limited at a sublethal level by differentiation to the non-replicative "stumpy" form and by the host immune response. Here, we derive continuous time equations to model the time-course, cell types and level of trypanosome parasitaemia, and compare the best fits with experimental data. The best fits that were obtained favour a model in which both density-dependent trypanosome differentiation and host immune response have a role in limiting the increase of parasites, much poorer fits being obtained when differentiation and immune response are considered independently of one another. Best fits also favour a model in which the slender-to-stumpy differentiation progresses in a manner that is essentially independent of the cell cycle. Finally, these models also make the prediction that the density-dependent trypanosome differentiation mechanism can give rise to oscillations in parasitaemia level. These oscillations are independent of the immune system and are not due to antigenic variation

Introducing Quality of Access Continuity: The Positive and Negative Effects of a Technology Affordance

Mobile devices offer technology affordances that were not previously available. With the rapid acceptance of these technologies it is imperative to understand and investigate both their positive and negative effects on individuals. In this ongoing research we have conceptualized an affordance of mobile devices in order to examine these positive and negative effects. Quality of Access Continuity is a 1st-order reflective, 2nd-order formative construct which is defined as the degree to which an employee or individual perceives they have a secure, continuous, usable, and reliable connection to the Internet or an intranet using a mobile device thus affording them the opportunity to accomplish tasks. The four components of this construct are discussed and the construct is then placed within a conceptual model which we hypothesize will show the duality of this affordance in regard to its effects on an individual’s strain

Tailoring Explanations for the User

In order for an expert system to provide the most effective explanations, it should be able to tailor its responses to the concerns of the user. One way in which explanations may be tailored is by point of view A method is presented for representing the knowledge to support different points of view in the current domain. In addition, we present a method for determining the point of view to take by inferring the user's goal within a brief discourse segment. The advising system's response to the derived goal depends on the strength of its belief in the inference for which a method of determination is also provided. This information enables the system to decide what answer to give to a question, which kind of justification is relevant, and when to provide it. Some details of the current implementation are included

The Impact of Antarctic Treaty Challenges on the US Military

While the Antarctic Treaty of 1961 largely prevented conflicts on the continent, growing challenges to the treaty system could affect the United States and the global community. Through historical documents and press reports, this article examines ice deterioration, unreported and unregulated fishing, resource extraction preparation, hostilities between treaty members, and the roles of China and Russia in the region. It provides recommendations for policymakers and military strategists on how the United States can maintain global security and treaty interests—and the potential request for intervention—within the guidelines of the National Security Strategy

Invited Paper: Survey of Technology and Skills in Demand: The 2022 Update

Faculty in the information systems (IS) and information technology (IT) fields are faced with the challenge to keep their curriculum relevant and current. What was taught two years ago will often be outdated and faculty must constantly update their curriculum on which courses should be taught as well as what should be taught within a particular course. This research continues a fifteen-year effort to help understand employer needs in terms of the skills they desire new hires to possess upon employment. This is the sixth version of this employer survey. The survey continues to report the responses of over 500 IS/IT professionals and was expanded to ask additional questions related to salary information. In addition, based on feedback from open-ended questions in a prior survey, new categories were added to the survey. Several key results and changes from prior surveys include that VR/AR (virtual reality/augmented reality) platforms showed the highest anticipated growth rate for all operating platforms in the next two years, analytics tools such as Apache Spark showed high growth rate, and JavaScript maintained the first position for programming languages

Taking the Initiative for System Goals in Cooperative Dialogue

We discuss the need for natural language systems to have a more flexible, conversational ability to interact with the user particularly for problem-solving dialogue. In particular, such systems need to have their own goals in addition to responding to the user's requests and the linguistic ability to manage such goals 10 the dialogue. We discuss some motivations for taking the initiative, the information necessary to do it, and present a partial solution to a subproblem. The approach is exemplified by output from our experimental dialogue ADVISOR which functions as an academic advisor to students
