In real-world applications, knowledge bases consisting of all the available information for a specific domain, along with the current state of affairs, will typically contain contradictory data, coming from different sources, as well as data with varying degrees of uncertainty attached. An important aspect of the effort associated with maintaining such knowledge bases is deciding what information is no longer useful; pieces of information may be outdated; may come from sources that have recently been discovered to be of low quality; or abundant evidence may be available that contradicts them. In this paper, we propose a probabilistic structured argumentation framework that arises from the extension of Presumptive Defeasible Logic Programming (PreDeLP) with probabilistic models, and argue that this formalism is capable of addressing these basic issues. The formalism is capable of handling contradictory and uncertain data, and we study non-prioritized belief revision over probabilistic PreDeLP programs that can help with knowledge-base maintenance. For belief revision, we propose a set of rationality postulates — based on well-known ones developed for classical knowledge bases — that characterize how these belief revision operations should behave, and study classes of operators along with theoretical relationships with the proposed postulates, including representation theorems stating the equivalence between classes of operators and their associated postulates. We then demonstrate how our framework can be used to address the attribution problem in cyber security/cyber warfare. 相似文献

Recent developments in computational cell and biomolecular mechanics have provided valuable insights into the mechanical properties of cells, subcellular components and biomolecules, while simultaneously complementing new experimental techniques used for deciphering the structure-function paradigm in living cells. These computational approaches have direct implications in understanding the state of human health and the progress of disease and can therefore aid immensely in the diagnosis and treatment of diseases. We provide an overview of the computational approaches that are currently used in understanding various aspects of cell and bimolecular mechanics. Our emphasis is on state-of-the-art techniques and the progress made in addressing key challenges in biomechanics. 相似文献

A miniaturized transient hot-wire device for measuring thermal conductivity of non-conductive fluids
This paper presents the design, fabrication and characterization of a novel transient hot-wire device for measurement of thermal conductivity of non-conductive fluids. The key features of the cell are small sample amount, simple fabrication, accurate measurement and transparency, which allows the study of both thermal and optical properties of the fluids. A 20 μm-diameter platinum hot wire is symmetrically suspended along the central axis of the capsulated cell to avoid the effect from the walls. A four-point resistance measurement method was used to measure the transient resistance with high accuracy. The accuracy of the thermal conductivity measurement was validated with reference values and very good agreement was achieved. 相似文献

Unlocking the secrets of the brain is a task fraught with complexity and challenge – not least due to the intricacy of the circuits involved. With advancements in the scale and precision of scientific technologies, we are increasingly equipped to explore how these components interact to produce a vast range of outputs that constitute function and disease. Here, an insight is offered into key areas in which the marriage of neuroscience and nanotechnology has revolutionized the industry. The evolution of ever more sophisticated nanomaterials culminates in network‐operant functionalized agents. In turn, these materials contribute to novel diagnostic and therapeutic strategies, including drug delivery, neuroprotection, neural regeneration, neuroimaging and neurosurgery. Further, the entrance of nanotechnology into future research arenas including optogenetics, molecular/ion sensing and monitoring, and piezoelectric effects is discussed. Finally, considerations in nanoneurotoxicity, the main barrier to clinical translation, are reviewed, and direction for future perspectives is provided. 相似文献

Full-adders are essential parts of digital circuits whereby many arithmetic circuits can be implemented by applying these cells. Therefore speed and power consumption of full-adders affect the performance of digital circuits, FA cell performs a predominant arithmetic operation in them. We utilise carbon nanotube field effect transistors for implementing our proposed designs due to their unique mechanical and electrical properties such as lower delay, lower power consumption, very dense and lower current off. Extensive simulation results using HSpice are reported to demonstrate the acquired significant improvement in performance of FA circuit design in comparison with the state-of-the-art work. 相似文献
