o bjectives: headgears are among the effective orthodontic appliances to achieve treatment goals. unilateral molar distal movement is sometimes needed during an orthodontic treat- ment, 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 uni- lateral expanded outer bow asymmetric hea...

High-resolution IRAS maps are used to search for the presence of stellar-wind bow-shocks around high-mass X-ray binaries (HMXBs). Their high space velocities, recently confirmed with Hipparcos observations, combined with their strong stellar winds should result in the formation of wind bow-shocks. Except for the already known bow-shock around Vela X-1 (Kaper et al. 1997), we do not find convinc...

Combining a physical model with a bow controller, we propose a technique to validate bow strokes in a virtual instrument.

Using the Wekinator software tool for real-time, interactive machine learning [3] and the K-Bow commercial sensor bow [5], we have constructed a realtime cello bow articulation classification system. This system is capable of outputting articulation labels (e.g., “legato,” “marcato,” “spiccato”) in real-time as a cellist performs. These labels, which are output via Open Sound Control [9], may b...

The interaction of high-velocity neutron stars with the interstellar medium produces bow shock nebulae, where the relativistic neutron star wind is confined by ram pressure. We present multi-wavelength observations of the Guitar Nebula, including narrow-band Hα imaging with HST/WFPC2, which resolves the head of the bow shock. The HST observations are used to fit for the inclination of the pulsa...

Retrieving similar questions in online Q&A community sites is a difficult task because different users may formulate the same question in a variety of ways, using different vocabulary and structure. In this work, we propose a new neural network architecture to perform the task of semantically equivalent question retrieval. The proposed architecture, which we call BOW-CNN, combines a bag-ofwords...

PURPOSE The purpose of this study was to compare the occlusal plane inclination of models mounted using 3 different systems for face-bow transfer with the actual occlusal plane inclination as measured on a cephalometric radiograph. PATIENTS AND METHODS Twenty-two subjects were enrolled in this study. Three alginate impressions of the maxillary dentition were taken, and 3 stone dental models w...

A derecho-producing bow-echo event over the central United States on 8 May 2009 is analyzed based on radar observations and a successful real-data WRF simulation at 0.8-km grid spacing. Emphasis is placed on documenting the existence, evolution, and characteristics of low-level mesovortices (MVs) that form along the leading edge of the bowing system. The genesis of near-surface high winds withi...

Automatic facial expression recognition (AFER) has undergone substantial advancement over the past two decades. This work explores the application of bag of words (BoW), a highly matured approach for object and scene recognition to AFER. We proceed by first highlighting the reasons that makes the task for BoW differ for AFER compared to object and scene recognition. We propose suitable extensio...

background: high tibia osteotomy (hto) is a common surgical operation for correction of genu varum deformity. in some patients,there are concurrent tibia vara and genu varum (bow leg). this study aimed to consider the possibility of better correction of bow leg deformity after double level tibial osteotomy (dlto). materials and methods: a case series of 10 patients of genu varum in addition to ...
