28 The fixpoints of Galois Connections form patterns in binary relational data, such as object29 attribute relations, that are important in a number of data analysis fields, including Formal 30 Concept Analysis (FCA), Boolean factor analysis and frequent itemset mining. However, the 31 large number of such fixpoints present in a typical dataset requires efficient computation 32 to make analysis...
Updating a concept lattice when introducing new objects to input data can be done by any of the so-called incremental algorithms for computing concept lattice of the data. The algorithms use and update the lattice while introducing new objects one by one. The present concept lattice of input data without the new objects is thus required before the update. In this paper we propose an efficient a...
BACKGROUND Community-based organizations (CBOs) are important stakeholders in health systems and are increasingly called upon to use research evidence to inform their advocacy, program planning, and service delivery. To better support CBOs to find and use research evidence, we sought to assess the capacity of CBOs in the HIV/AIDS sector to acquire, assess, adapt, and apply research evidence in ...
The hardwood forests of the southern U.S. are not naturally composed of singe predominant species. The diversity of tree species within these stands is one of the qualities that make them so valuable for multiple use stand management. While many of the best hardwood sites have been planted to pines since the 1950’s, some proportion of these pine stands now being harvested may need to be refores...
BACKGROUND AND PURPOSE To evaluate the mechanisms of failure of blood oxygenation level-dependent (BOLD) imaging in stroke, we compared the evoked cerebral blood oxygenation (CBO) responses and activation volumes (AVs) of BOLD functional MRI (fMRI) in chronic stroke patients with moderate and severe cerebral ischemia. METHODS We measured the evoked CBO responses in the primary sensorimotor co...
In this paper, we propose a predictor-corrector type Consensus Based Optimization(CBO) algorithm on convex feasible set. Our proposed generalizes the CBO in [11] to tackle constrained optimization problem for global minima of non-convex function defined domain. As practical application algorithm, study portfolio finance. application, introduce an objective choose optimal weight each asset asset...
OBJECTIVES To explore models to improve HIV testing, linkage to care and treatment among men who have sex with men (MSM) in cooperation with community-based organizations (CBOs) in China. METHODS We introduced a new model for HIV testing services targeting MSM in six cities in 2013.These models introduced provision of rapid HIV testing by CBO staff and streamlined processes for HIV screening,...
Blood-oxygen-level-dependent contrast functional magnetic resonance imaging (BOLD-fMRI) has been used to perform functional imaging in brain disorders such as stroke and brain tumors. However, recent studies have revealed that BOLD-fMRI does not image activation areas correctly in such patients. To clarify the characteristics of the evoked cerebral blood oxygenation (CBO) changes occurring in s...
One of the most important factors that affects construction costs of highways is the earthwork cost. On the other hand, the earthwork cost strongly depends on the design of vertical alignment or project line. In this study, at first, the problem of vertical alignment optimization was formulated. To this end, station, elevation and vertical curve length in case of each point of vertical intersec...
