an abrupt global warming event has been recorded in many parts of the world in sediments of latest maastrichtian age between 65.45-65.10 ma. this warm event was documented here at a section near ziyarat-kola in central alborz based on analysis of planktonic foraminifera. an unusual abundance of normally large-size species such as globotruncana arca, globigerinelloides subcarinatus, pseudoguembe...

public health management is a pillar of public health practice. only through effective management can research, theory, and scientific innovation be translated into successful public health action. with this in mind, the u.s. centers for disease control and prevention (cdc) has developed an innovative program called improving public health management for action (impact) which aims to address th...

despite a renewed focus in the field of global health on strengthening health systems, inadequate attention has been directed to a key ingredient of high-performing health systems: management. we aimed to develop the argument that management – defined here as the process of achieving predetermined objectives through human, financial, and technical resources – is a cross-cutting function necessa...

the current limited focus on management in global health activities is highly problematic given the amounts of financial and human resources that are pouring into health system strengthening interventions and the complexity of clinical operations across settings. by ensuring that public health and healthcare practitioners in domestic and international settings receive management training in the...

the last decade has ushered in a rapidly expanding global discussion regarding acellular dermal matrix (adm) applications, economic analyses, technical considerations, benefits, and risks, with recent emphasis on adm use in breast surgery. this study aims to evaluate global trends in adm research using bibliometric analysis. the top nine plastic surgery journals were determined by impact factor...

a new meta-heuristic method, based on neuronal communication (nc), is introduced in this article. the neuronal communication illustrates how data is exchanged between neurons in neural system. actually, this pattern works efficiently in the nature. the present paper shows it is the same to find the global minimum. in addition, since few numbers of neurons participate in each step of the method,...

walking being the oldest form of urban transport, and until the advent of major transformationsin transport technology in the nineteenth century, most cities were structured in ways that supported walkability.today, there is a change in transportation which emphasizes, the traditional pedestrian paths which are increasinglybecoming non-regulated spaces when compared to the urban spaces for auto...

knowing the fact that the main weakness of the most standard methods including k-means and hierarchical data clustering is their sensitivity to initialization and trapping to local minima, this paper proposes a modification of convex data clustering  in which there is no need to  be peculiar about how to select initial values. due to properly converting the task of optimization to an equivalent...
