The airlines reorganization will accelerate the switch of the Chinese mainland civil aviation system from a former point-to-point (PP) structure to a hub-and-spoke (HS) network. In such a context, the major efforts of our paper are put into identifying hub airports in mainland China. We first analyze the HS network’s competitive advantages and find four desirable hub characteristics. A three-le...

INTRODUCTION Sci-Hub is a useful web portal for people working in science as it provides access to millions of free scientific articles. Satisfaction and usage should be explored in the Latino student population. The objective of this study was to evaluate the use, knowledge, and perception of the scientific contribution of Sci-Hub in medical students from Latin America. METHODOLOGY A multice...

The retina is a specialized sensory organ, which is essential for light detection and visual formation in the human eye. Inherited retinal degenerations are a heterogeneous group of eye diseases that can eventually cause permanent vision loss. UPR (unfolded protein response) and ER (endoplasmic reticulum) stress plays an important role in the pathological mechanism of retinal degenerative disea...

In this paper, a new priority M/M/c queuing hub covering problem is presented, in which products with high priority are selected for service ahead of those with low priority. In addition, a mixed-integer nonlinear mathematical programming model is presented to find a good solution of the given problem. Due to its computational complexity, we propose a multi-objective parallel simulated annealin...

What is the best distribution strategy to ship materials from a source to multiple destinations on a regular basis? This is a common question confronting logistics planners in many industries. This paper examines this issue in the context of the ocean freight industry. In particular, we tackle the economics of freighting raw materials through a transshipment hub, and propose a method to synchro...

We have been implementing the research work in order to achieve the rural clinics that can provide the similar quality of clinic performance as that of urban general hospitals. The research work involves the use of common fund in community, from the financial viewpoint, for the purpose of continuous management of clinics in rural villages of developing countries, and the introduction of telemed...

Wireless sensor networks are a web of sensor nodes with an arrangement of processor and restricted memory unit implanted in it. Dependable steering of parcels from the sensor hub to its base station is the most imperative undertaking for the systems. In remote sensor systems, steering is bit more unpredictable than other wired or remote systems. The steering conventions connected for alternate ...

Conventional document and discussion websites provide users with no help in assessing the quality or quantity of evidence behind any given idea. Besides, the very meaning of what evidence is may not be unequivocally defined within a community, and may require deep understanding, common ground and debate. An Evidence Hub is a tool to pool the community collective intelligence on what is evidence...

The world is witnessing an unprecedented growth in the usage of herbal products. India is a mother hub for natural herbs based science. Herbal drug technology is used for converting botanical materials into medicines, where standardization and quality control with proper integration of modern scientific techniques and traditional knowledge is important. For global harmonization WHO specific gui...
