granular cell tumor is a rare benign neoplasm most commonly appears in the head and neck region, especially in the tongue, cheek mucosa, and palate. occurrence in limbs is even rarer. these tumors account for approximately 0.5% of all soft tissue tumors. granular cell tumor can also affect other organs including skin, breast, and lungs. local recurrence and metastasis is potentially higher in m...

OBJECTIVES Headgears are among the effective orthodontic appliances to achieve treatment goals. Unilateral molar distal movement is sometimes needed during an orthodontic treatment, which can be achieved by an asymmetric headgear. Different unilateral headgears have been introduced. The main goal of this study was to analyze the force system of unilateral expanded outer bow asymmetric headgears...

In this paper we propose the use of several feature extraction methods, which have been shown before to perform well for object recognition, for recognizing handwritten characters, These methods are the histogram of oriented gradients (HOG), a bag of visual words using pixel intensity information (BOW), and a bag of visual words using extracted HOG features (HOG-BOW). These feature extraction a...

In this paper the near-field distributions of bow-tie apertures in visible range are characterized by the method of 3D finite-difference time-domain (FDTD). The numerical simulation results reveal theoretically the relation of field enhancement effect of bow-tie aperture and its several parameters including tip angle, aperture size and film thickness. For the bow-tie aperture with a certain tip...

The aim of this short term mission is to work at the Medialogy Department of the Aalborg University in Copenhagen to a project with Prof. Stefania Serafin. The work that we would like to do together is related to an ongoing project about a well known HCI predictive model in an audio perspective: the Fitts’ model has been analyzed providing different audio interactive displays and interfaces in ...

(The image quality has been reduced to submit this paper to astro-ph. To get a full resolution version, please visit A new point of view on the dynamics of the circumstellar nebula M1-67 around the runaway Wolf-Rayet (WR) star WR 124 is presented. We simulated the outbursts of nebulae with different morphologies, to compare the results to the observed dynamical spectra of M1-67. We found that i...

Understanding tie strength in social networks, and the factors that influence it, have received much attention in a myriad of disciplines for decades. Several models incorporating indicators of tie strength have been proposed and used to quantify relationships in social networks, and a standard set of structural network metrics have been applied to predominantly online social media sites to pre...

We present a new system to measure the position and force parameters most relevant to violin bowing technique. It is stable and reliable, and as it allows players to perform without impediment and consists of minimal equipment, it is also suitable for use in professional performance settings. This measurement system, implemented on a carbon fiber bow, relies on an electromagnetic field sensing ...

Field-aligned beams are known to originate from the quasi-perpendicular side of the Earth’s bow shock, while the diffuse ion population consists of accelerated ions at the quasi-parallel side of the bow shock. The two distinct ion populations show typical characteristics in their velocity space distributions. By using particle and magnetic field measurements from one Cluster spacecraft we prese...
