Bayesian networks provide a powerful intelligent information fusion architecture for modeling probabilistic and causal patterns involving multiple random variables. This paper advances a computable theory of learning discrete Bayesian networks from data. The theory is based on the MAP-MDL principles for maximizing the joint probability or interchangeably miniziming the joint description length ...

We derive novel upper and lower finite length bounds of the error probability in joint source-channel coding when the source is distributed according to an ergodic Markov process and the channel is a Markovian additive channel or a Markovian conditional additive channel. We show that these bounds are tight in the moderate deviations regime and for a certain interval of rates, also in the large ...

The forces induced in tiny wrist joint ligaments must be estimated in order to understand their role in the mechanism of the joint. We estimated forces in a number of selected ligaments in seven human wrist joint specimens, using a noninvasive method. The method is based on the rationale that the force generated in a ligament depends on its change of length with the joint under load. In vitro l...

OBJECTIVES To explore the anatomy of the plantar aponeurosis (PA) and its biomechanical effects on the first metatarsophalangeal (MTP) joint and foot arch. METHODS Anatomic parameters (length, width and thickness of each central PA bundle and the main body of the central part) were measured in 8 cadaveric specimens. The ratios of the length and width of each bundle to the length and width of ...

BACKGROUND This study aimed to assess the efficacy and safety of atropine 0.5% eyedrops (ATE) for the treatment of children with low myopia (LM). METHODS In this study, a total of 126 children with LM were randomly divided into an intervention group (administered 0.5% ATE) and a control group (administered a placebo), with 63 children in each group. The outcome measurements were changes in th...

PURPOSE To generate percentile curves of axial length (AL) for European children, which can be used to estimate the risk of myopia in adulthood. METHODS A total of 12 386 participants from the population-based studies Generation R (Dutch children measured at both 6 and 9 years of age; N = 6934), the Avon Longitudinal Study of Parents and Children (ALSPAC) (British children 15 years of age; N ...

This article uses nineteenth-century evidence to calculate the impact of early exposure to malaria-ridden environments on nutritional status and the immune system in America. I estimate the risk of contracting malarial fevers in the 1850s by using correlations between malaria and environmental factors such as climate and geographical features. The study demonstrates that Union Army recruits who...

In this paper the influence of knee joint on the motion of the robot and the effect of leg segmental proportions and angle between leg segments on the performance of the robot is explored via parametric analysis. The spring loaded inverted pendulum (SLIP) running in the sagittal plane, which is a simple model commonly used to analyze the basic qualitative properties of running, is used. The per...

In this paper we propose a revisitation of the topic of unique decodability and of some of the related fundamental theorems. It is widely believed that, for any discrete source X, every “uniquely decodable” block code satisfies E[l(X1, X2, · · · , Xn)] ≥ H(X1, X2, . . . , Xn), where X1, X2, . . . , Xn are the first n symbols of the source, E[l(X1, X2, · · · , Xn)] is the expected length of the ...

This study presents a subject-specific method of determining the zero-load lengths of the cruciate and collateral ligaments in computational knee modeling. Three cadaver knees were tested in a dynamic knee simulator. The cadaver knees also underwent manual envelope of motion testing to find their passive range of motion in order to determine the zero-load lengths for each ligament bundle. Compu...
