Similarity method is the key of the user-based collaborative filtering recommend algorithm. The traditional similarity measures, which cosine similarity, adjusted cosine similarity and Pearson correlation similarity are included, have some advantages such as simple, easy and fast, but with the sparse dataset they may lead to bad recommendation quality. In this article, we first research how the...

Registration of a population of diffusion tensor images (DTIs) is one of the key steps in medical image analysis, and it plays an important role in the statistical analysis of white matter related neurological diseases. However, pairwise registration with respect to a pre-selected template may not give precise results if the selected template deviates significantly from the distribution of imag...

This paper examines the relationship between open innovation (OI) practices (inbound and coupled) performance in service firms. Specifically, it invokes a dynamic capabilities perspective to propose differential moderating effects of two forms reconfiguration capabilities, strategic capability (SRC) operational (ORC), on focal relationship. Based sample sector firms drawn from UK Community Inno...

Numbers have emerged historically as by far the most popular form of representation. All our basic scientific paradigms are built on the foundation of these, numeric, or quantitative, concepts. Measurement, as conventionally understood, is the corresponding process for (numeric) representation of objects or events, i.e., it is a procedure or device that realizes the mapping from the set of obje...

In this study, the neuroprotective effect of an extract of Antrodia camphorata (A. camphorata), a fungus commonly used in Chinese folk medicine for treatment of viral hepatitis and cancer, alone or in combination with aspirin was investigated in a rat embolic stroke model. An ischemic stroke was induced in rats by a selective occlusion of the middle cerebral artery (MCA) with whole blood clots ...

Purpose The aim of this paper is to uncover the main capabilities that a luxury hotel needs develop when functioning as orchestrator local gastronomic business ecosystem. Design/methodology/approach Given limited attention previous literature has placed on role hotels orchestrators in ecosystems, adopts qualitative approach, i.e. exploratory analysis single case study: Italian high-end Borgo Eg...

With the rise of concept environmental protection and attention all sectors society to ecological environment, selection green suppliers is a hot topic. In this paper, we develop combinative distance-based assessment (CODAS) method in probabilistic hesitant fuzzy sets (PHFSs) cope with multiple attributes group decision making (MAGDM). A standardized approach that integrates methods applied nor...

Galactosidase ( -Gal) staining is widely used to demonstrate specific gene expression during evaluation of gene targets in vivo. This technique is extremely sensitive to fixation. Optimal fixation conditions are necessary to obtain the maximal -Gal activity. In this experiment, Carnoy’s and three different aldehyde fixatives were used at different temperatures and over different time points. Ki...

In this paper, we propose a multi-beam model for antenna array pattern synthesis (AAPS) problem. The model uses a conic trust region algorithm (CTRA) similarly proposed in this paper to optimize its cost function. Undoubtedly, whole algorithm efficiency ultimately lies on the CTRA, thereof, we propose a method to improve the iterative algorithm’s efficiency. Unlike traditional trust region meth...
