What is this?5 answersThis invention describes an electronic control device operated by the human sole, primarily designed for computers. It consists of a support structure accommodating the human sole, a resting surface shaped to conform to the average human sole's contours, and switch elements protruding from the support structure with electric switch contacts and activating surfaces. Multiple switch elements can be activated by lateral and/or downward pressure, strategically placed along the internal, external, rear, or front boundaries of the resting surface. This innovative design allows for intuitive control through foot movements, enhancing user experience and accessibility. Additionally, the concept of spectrally arbitrary ray patterns and the dynamics of modulationally unstable plane waves in specific equations are explored in other research papers.
What is this about?4 answersSymmetric Searchable Encryption (SSE) allows users to securely search over encrypted data stored in untrusted third-party services. Most SSE schemes are designed for cloud services, but this paper explores the possibility of using SSE in the Internet of Things (IoT) services. The authors propose a forward private dynamic SSE scheme that can run on resource-constrained devices in a fog node scenario. The scheme allows edge devices to encrypt data locally and store it in the cloud, while still enabling users to search for specific keywords over the encrypted data. The scheme achieves efficient computational operations, supports the multi-client model, and is proven to be secure against malicious adversaries.
The paper discusses the Department of Health's SR2002 Public Service Agreement, which outlines objectives for transforming the healthcare system to deliver better health. Some objectives, such as reducing wait times for hospital treatment and in A&E, are reasonable but challenging to achieve. Other objectives, like enhancing accountability to patients and reducing mortality from heart disease and cancer, lack clear direction and depend on factors beyond the control of healthcare staff. The paper argues for setting realistic objectives and focusing on what healthcare staff can realistically achieve, rather than setting objectives based on uncertain knowledge or unrealistic expectations.
The paper describes a novel route for the synthesis of highly substituted 1,1'-carbonylbispyrazole derivatives through a cyclocondensation reaction. The reaction involves the use of 1H-pyrazole-1-carbohydrazide and α,β-unsaturated nitriles under suitable conditions. This method provides a new approach for the synthesis of these derivatives.
The paper discusses the ongoing debate in psychiatry on how to effectively treat schizophrenia, particularly in terms of maintenance treatment with antipsychotic medication after remission of a first-episode psychosis. Different perspectives are presented, with some arguing for long-term medication treatment to prevent relapse and treatment resistance, while others caution against overreliance on medication and emphasize the potential harmful effects. The paper highlights the lack of clear evidence and consensus on this issue, suggesting the need for ongoing research and a cautious approach to prescribing antipsychotics.
The paper describes the discovery of two new species of Metridius, a genus of insects found infesting sugarcane stools in Australia. The species, M. robertsoni and M. mcalpinei, are characterized by winged males and apterous females. The paper provides information on the biology of these species and includes an identification key for the genera of the subfamily Chiromyzinae and the species within it.
What's the theory?5 answersTheory plays a crucial role in qualitative research, guiding the choice of theory used to explore and explain the research topic. It is also present in the ontological, epistemological, and methodological decisions made throughout the research process. Existing approaches to using theory in qualitative research have been synthesized, focusing on advice found in peer-reviewed journal articles. A framework is proposed that outlines the use of theory at five stages of a qualitative research study: pre-design, during design, data collection, data analysis, and writing up. The role and purpose of theory vary depending on the stage of the research.Theory is defined as the formation of testable hypotheses, while empirical work involves hypothesis testing. Models, mathematics, and methods serve as the operational link between theory and empirical work. Multiple hypotheses and auxiliary assumptions may be intertwined, making it difficult to discern which one is falsified by a given data set. However, hypothesis formation and testing remain fundamental to science. The structure of theoretical papers and proposals can be understood within a tripartite parsing of science, consisting of theory, empirical work, and math/models/methods.Theory is a hybrid genre that developed in artistic, activist, and academic circles as a critique of canonical models and institutions of scientific and philosophical work. Jacques Derrida, Paul de Man, and Richard Rorty provide different perspectives on the question of "what is theory?" For Derrida, the question of "what is?" underlies our understanding of truth, consciousness, and subjectivity, particularly through the concept of writing. Theory is primarily practiced in the academic sphere in the USA.A measure of statistical evidence should satisfy the criterion of consistency, meaning that if the evidence strongly testifies against a hypothesis, then that hypothesis should indeed not be true. The p-value is not consistent, while the ratio of likelihoods is consistent.While many model selection criteria have been suggested, researchers still rely on R2 and R -2 due to their informational content. However, other superior criteria can convey the same dimensions of information.
What is it about?3 answersThis chapter offers an analysis of the first book of the History, paying particular attention to the distinctive structure of Book 1. Moltmann looks towards a future in which God will restore everything; this is the great hope which strengthens our little hopes. In this second "Fourth World" volume, the evil Darkseid's schemes continue to unfold while the New Gods, Forever People, Mister Miracle and other heroes battle his minions. There is simply no other book like it--an Oxford scholar presents a genuine global history, spanning ten centuries and examining and weaving together events and movements in every part of the world. How odd it is that the book’s current status in America is falling away, even as many people try to save it—its content and even physical existence—from disintegration.
What is this article about?4 answersIn recent years, there has been a focus on utilizing automatic information extraction to mine and exploit the large amount of accumulated data in geological journals and report literature. This paper introduces the concept of extreme summarization, a task that aims to create a short, one-sentence news summary answering the question "What is the article about?". The authors argue that extreme summarization requires an abstractive modeling approach rather than extractive strategies. They propose a novel abstractive model based on convolutional neural networks that outperforms existing approaches in capturing long-range dependencies and recognizing pertinent content. Additionally, the importance of literature reviews in providing a comprehensive overview of the current state of knowledge and identifying gaps in the evidence base is highlighted. Overall, these papers contribute to the development of automatic summarization techniques and the understanding of the role of literature reviews in research.
What is this about?4 answersThis is about the process of decision-making in various aspects of human culture, such as politics, technology, theology, ideology, law, and literature. It explores how decisions are influenced by individual actions as well as collective transformations, and how they can have both immediate and long-term consequences. The paper also discusses the factors that shape decision-making in complex activities like teaching, including a person's knowledge, goals, and beliefs. Additionally, it mentions the disruption caused by the access to massive amounts of digital data and advanced analytical tools, and how this is impacting both practice and academia.
