BACKGROUND Given that a substantial number of daily activities take place in neighborhoods, a convenient and effective method for measuring the physical activity of individuals is needed. Therefore, we tested the validity and reliability of the Korean version of the Neighborhood Physical Activity Questionnaire (K-NPAQ), which was developed through translation and back-translation of the NPAQ. ...

We present a new method to estimate noise for a single-slice sinogram of low-dose CT based on the homogenous patches centered at a special pixel, called center point, which has the smallest variance among all sinogram pixels. The homogenous patch, composed by homogenous points, is formed by the points similar to the center point using similarity sorting, similarity decreasing searching, and var...

This work incorporates the multi-modality of the data distribution into a Gaussian Process regression model. We approach the problem from a discriminative perspective by learning, jointly over the training data, the target space variance in the neighborhood of a certain sample through metric learning. We start by using data centers rather than all training samples. Subsequently, each center sel...

We show that with a Next Generation Large Telescope one can detect the accelerated motions of ∼ 100 stars orbiting the massive black hole at the Galactic center. The positions and velocities of these stars will be measured to astrometric and spectroscopic precision several times better than currently attainable enabling detailed measurements of the gravitational potential in the neighborhood of...

We prove that for $r \in \mathbb{N}\_{\geq 2} \cup {\infty}$, any dynamically coherent, center bunched and strongly pinched volume preserving $C^r$ partially hyperbolic diffeomorphism $f \colon X \to X$, if either (1) its foliation is uniformly compact, or (2) center-stable center-unstable foliations are of class $C^1$, then there exists a $C^1$-open neighborhood $f$ in $\operatorname{Diff}^r(X...

Similarly to protein folding, the association of two proteins is driven by a free energy funnel, determined by favorable interactions in some neighborhood of the native state. We describe a docking method based on stochastic global minimization of funnel-shaped energy functions in the space of rigid body motions (SE(3)) while accounting for flexibility of the interface side chains. The method, ...

Abstract The urban structure of Dombóvár has been transformed in recent centuries, and the protected buildings that once defined town center, have relegated to periphery. Today, despite its rich architectural heritage, Kakasdomb district is an area at risk segregation. key integration into existing tissue utilization including former synagogue building. This paper examines possibilities for reu...

BACKGROUND Neighborhood sociodemographic characteristics are associated with health care utilization across many conditions. There has been little study of whether total knee replacement (TKR) recipients from vulnerable populations, including racial and ethnic minorities, the poor, the elderly, and the less well educated, are more likely to use low-volume hospitals (LVHs). METHODS We used Med...

The following is a transcript of a talk in Center for Cities & Schools speaker’s series. Housed in the Institute of Urban and Regional Development (IURD) at Berkeley and affiliated with the Graduate School of Education (GSE) and the Department of City and Regional Planning (DCRP), The Center for Cities & Schools is committed to bridging the fields of education and urban policy to create equitab...

This study examines the outcome of shopping center development as reflected in their built forms. Specifically, this research explores if the design attributes of the shopping centers are related to their economic and walkability characteristics. This is a cross-sectional study focusing on 19 neighborhood shopping centers in Houston, TX, each with a supermarket chain store. It assessed design a...
