OBJECTIVES to propose standardisation of fourth ventricle dimensions and to study its characteristics in neurocysticercosis. METHOD a control group (CG) constituted by 114 individuals with normal CT, and 80 patients with neurocysticercosis composed the group with neurocysticercosis (GN). Measures of the inner cranial diameter (Cr), fronto-polar distance between both lateral ventricles (FP), a...
In order to handle complex face image variations in face recognition, multi-image face recognition has been proposed, instead of using a single still-imagebased approach. In many practical scenarios, multiple images can be easily obtained in enrollment and query stages, for example, using video. By accessing these images, a good ”quality” image(s) will be used for recognition using conventional...
background: the aim of this study was to evaluate the association of socioeconomic status (ses) with anthropometric measures and bp in iranian children and adolescents. methods: this nationwide study was conducted in 2011-2012 among 14,880 students, aged 6-18 years, selected by multistage, cluster-sampling method from rural and urban areas of 30 provinces of iran. anthropometric indexes and bp ...
International standards for calculating heart period variability (HPV) from a series of R-wave intervals (R-R) in an electrocardiographic (ECG) recording have been widely accepted. It is possible, and potentially useful in various settings, to use systolic blood pressure waveform intervals to estimate HPV, but the validity of HPV derived from blood pressure (BP) waveforms has not been establish...
Climate change will worsen the high levels of urban vulnerability in Latin American cities due to specific environmental stressors. Some impacts of climate change, such as high temperatures in urban environments, have not yet been addressed through adaptation strategies, which are based on poorly supported data. These impacts remain outside the scope of urban planning. New spatially explicit ap...
Some concern about recently published nonpatient data, plus the fact that some records in the published sample of 600 nonpatients (Exner, 2001) were collected more than 20 years ago, prompted the initiation of a project to develop a new nonpatient sample. In this article, findings are presented for the first 175 participants tested in the new project. It is noted that the data from the new proj...
This paper proposes a reduced rank regression framework for constructing coincident and leading indexes. Based on a formal definition that requires that the first differences of the leading index are the best linear predictor of the first differences of the coincident index, it is shown that the notion of polynomial serial correlation common features can be used to build these composite variabl...
This thesis defines and designs succinct indexes for several abstract data types (ADTs). The concept is to design auxiliary data structures that ideally occupy asymptotically less space than the information-theoretic lower bound on the space required to encode the given data, and support an extended set of operations using the basic operators defined in the ADT. As opposed to succinct (integrat...
We review the existing literature on measurement of human capital. Broadly speaking, economists have proposed three approaches to constructing capital measures—the indicator approach, cost and income approach. Studies employing approach used single measures such as average years schooling or indexes multiple measures. The values investments based spending. by looking forward increment expected ...
Health programs and activities today include a great variety of public and private efforts directed toward both fatal and nonfatal conditions. Most accepted summary measures of a population's health status, on the other hand, are based on death rates alone. They tell little about the health of the living and therefore provide an in-adequate basis for assessing the need for and success of many h...
