Recommended body mass index cutoff values for overweight screening programs in Australian children and adolescents: comparisons with North America values. To our knowledge, only one report describing nipple diameters in pubertal boys has been published. 1 We studied 462 boys, aged 8–17 years, to determine if nipple diameter might provide measurable criteria for assessing sexual maturation durin...

BACKGROUND The preferred treatment of intertrochanteric fractures in aged patients is controversial. The purpose of the present study was to evaluate the outcomes of the Asian proximal femur intramedullary nail antirotation system (PFNA-II) for stabilization of such fractures. METHODS The PFNA-II was used to treat intertrochanteric fractures in 163 elderly patients from March 2010 to March 20...

Several studies have shown the importance of two very different descriptors for shape: symmetry structure and curvature extrema. The main theorem proved by this paper, i.e. the Symmetry-Curvature Duality Theorem, states that there is an important relationship between symmetry and curvature extrema: If we say that curvature extrema are of two opposite types, either maxima or minima, then the the...

A number of useful image and video processing techniques, ranging from low level operations such as denoising and detail enhancement to higher level methods such as object manipulation and special effects, rely on piecewise-smooth functions computed from the input data. In this thesis, we present two computationally efficient data structures for representing piecewise-smooth visual information ...

BACKGROUND The Proximal Femoral Nail Antirotation (PFNA) system for treatment of intertrochanteric fractures is currently widely applied worldwide. However, even though the PFNA has produced good clinical outcomes, a poor introduction technique with an inappropriate entry point can cause surgical complications. Some researchers suggest improving clinical outcomes by modifying the entry point, b...

Galaxy-scale strong gravitational lens systems are useful for a variety of astrophysical applications. However, their use is limited by the relatively small samples of lenses known to date. It is thus important to develop efficient ways to discover new systems both in present and forthcoming datasets. For future large high-resolution imaging surveys we anticipate an ever-growing need for effici...

Darin besteht das Wesen der Wissenschaft. Zuerst denkt man an etwas, das wahr sein könnte. Dann sieht man nach, ob es der Fall ist und im Allgemeinen ist es nicht der Fall. Summary Claimed as renewable energy source, wood is increasingly used in stoves and boilers for heating purposes in western countries due to economic reasons and environmental consciousness. Consequently, domestic wood combu...

Background and objective: In the academia, controversy over transformation of Panseokbo has continued.Methods: To analyze changes in name, shape, structure from 1970s to 2021, a survey was conducted based on reliable data including excavation, repair maintenance reports. Academic papers books were also reviewed where additional fact-checking required.Results: The results study are as follows. F...

This paper presents a case study on the mechanical design and fabrication of the Pico Radio Test Bed: a wireless networking node produced from off–the-shelf components for experimentation with applications, networking, media access layer design, and position locating algorithms. Particular focus is placed on the systematic design process and resolving coupling design constraints between the mec...

Transitory loss of airway patency in sedated pediatric dental patients is generally managed easily by extending the patient's head and neck to restore an open airway. This procedure can be difficult if the patient is restrained in a rigid support, such as a Papoose Board®. Modification of the small Papoose Board to allow extension of the head is accomplished by cutting off the upper 89 inches o...
