Secure group communication systems become more and more important in many emerging network applications. For a secure group communication system, an efficient and robust group key management approach is essential. In this paper, a new group key management approach with a group controller GC using the theory of hyper-sphere is developed, where a hyper-sphere is constructed for the group and each...

Although serrated polyps were historically considered to pose little risk, it is now understood that progression down the serrated pathway could account for as many as 15%-35% of colorectal cancers. The sessile serrated adenoma/polyp (SSA/P) is the most prevalent pre-invasive serrated lesion. Our objective was to identify the CpG loci that are persistently hyper-methylated during serrated carci...

Grouping problems are hard to solve combinatorial optimisation problems which require partitioning of objects into a minimum number of subsets while a given objective is simultaneously optimized. Selection hyper-heuristics are high level general purpose search methodologies that operate on a space formed by a set of low level heuristics rather than solutions. Most of the recently proposed selec...

Hypertexture is a powerful and exible procedural modeling tool that is currently limited only by an ine cient rendering mechanism. We analyze the terms of hypertexture functions to obtain an importance measure, capitalize on spatial and image coherence when possible. These enhancements make a guaranteed algorithm for ray-tracing implicit surfaces signi cantly more e cient for rendering hypertex...

RNA editing results in post-transcriptional modification and could potentially contribute to carcinogenesis. However, RNA editing in advanced lung adenocarcinomas has not yet been studied. Based on whole genome and transcriptome sequencing data, we identified 1,071,296 RNA editing events from matched normal, primary and metastatic samples contributed by 24 lung adenocarcinoma patients, with 91....

Brain connectivity network has been used for diagnosis and classification of neurodegenerative diseases, such as Alzheimer's disease (AD) as well as its early stage, i.e., mild cognitive impairment (MCI). However, conventional connectivity network is usually constructed based on the pairwise correlation among brain regions and thus ignores the higher-order relationship among them. Such informat...

HyFlex (Hyper-heuristic Flexible framework) [15] is a software framework enabling the development of domain independent search heuristics (hyper-heuristics), and testing across multiple problem domains. This framework was used as a base for the first Cross-domain Heuristic Search Challenge, a research competition that attracted significant international attention. In this paper, we present one ...

The reconstruction of sparse signal is an active area research. Different from a typical i.i.d. assumption, this paper considers non-independent prior group structure. For more practical setup, we propose EM-aided HyGEC, new algorithm to address the stability issue and hyper-parameter facing other algorithms. instability problem results ill condition transform matrix, while unavailability hyper...

Hybrid number system is a generalization of complex, hyperbolic and dual numbers. numbers hybrid polynomials have been the subject much research in recent years. In this paper, hybrinomials related to hyper-Fibonacci hyper-Lucas are defined. Then some algebraic properties newly defined examined such as recurrence relations summation formulas. Also, relation between given. Additionally, by using

this paper provides a review on major ergodic features of semi-independent hyper mv {algebra dynamical systems. theorems are presentedto make contribution to calculate the entropy. particularly, it is proved that thetotal entropy of those semi-independent hyper mv {algebra dynamical systemsthat have a generator can be calculated with respect to their generator ratherthan considering all the par...
