In quantifying the amount of gray matter in a population, voxelbased morphometry (VBM) and cortical thickness analysis are the two most widely used techniques. There are still many unanswered methodological questions regarding these methods. It is not clear what is the optimal amount of registration needed in VBM. It is assumed that the gray matter density obtained in the VBM will be positively...

Bipolar depression (BD) is a common psychiatric illness characterized by deficits in emotional and cognitive processing. Abnormalities in the subregions of the insula are common findings in neuroanatomical studies of patients with bipolar disorder. However, the specific relationships between morphometric changes in specific insular subregions and the pathogenesis of BD are not clear. In this st...

The theory of powerlists was recently introduced by Jay Misra. It gives us the ability to specify and verify certain parallel algorithms and connection structures. The notation is similar to sequential functional programming languages (such as Miranda TM Tur86]) but with constructs for expressing balanced division of lists. In the rst part of this work we study how some known algorithms for the...

The characterization of gray matter morphology of individual brains is an important issue in neuroscience. Graph theory has been used to describe cortical morphology, with networks based on covariation of gray matter volume or thickness between cortical areas across people. Here, we extend this research by proposing a new method that describes the gray matter morphology of an individual cortex ...

Economists inside and outside of the Austrian-school tradition have formulated a subjectivist theory of mineral resources. While von Mises (1940) presented a rudimentary theory, institutionalist Zimmermann (1933 and after) provided an indepth mind-centered approach distinct from the objective, neoclassical theory for minerals developed by Jevons (1865, 1866), Gray (1913), and Hotelling (1931). ...

botrytis cinerea is an important pathogen that causes diseases in ornamental crops. in presentresearch several greenhouses of roses located in central region of iran were surveyed toidentify the botrytis cinerea. a total of 80 isolates were collected from rose greenhouses incentral region of iran. morphological identification was based on characters such asconidiophore and conidial length. acco...

By introducing the theory of system safety science, and applying the gray theory prediction method, this paper aims at analysing the major hazards of spontaneous combustion of coal, and divided the impact indicators system into three categories, namely; static indicator, dynamic indicator, and intensive monitoring indicator. The static class indicator determined the hazard class by using risk e...

The distribution of diagnosis-associated information in histological slides is often spatial dependent. A reliable selection of the slide areas containing the most significant information to deriving the associated diagnosis is a major task in virtual microscopy. Three different algorithms can be used to select the appropriate fields of view: 1) Object dependent segmentation combined with graph...
