Cholesteatoma is a collection of keratinous debris and stratified squamous epithelium. It is trapped in the middle ear and can lead to bony erosion. The disease is treated surgically often followed by a second-look procedure to check for residual tissue or recurrence. Cholesteatoma has specific signal-intensity characteristics on magnetic resonance imaging with very high signal intensity on dif...

In order to quantitatively characterize the enhancement of hole mobility of strained silicon under different stress intensity conditions, changes of hole effective mass should be studied. In the paper, strained silicon under in-plane biaxially tensile strain based on (0 0 1) substrate and longitudinal uniaxially compressive strain along h1 1 0i are investigated thoroughly. By solving the Hamilt...

Apricot (Prunus armeniaca L.) is the most common, high-income generative fruit and consequently plays an important part in region's socio-economic growth. However, apricots are susceptible to several diseases pests that cause lower yields significant financial losses, including apricot shot hole disease brought on by Wilsonomyces carpophilus, a polyphagous fungus, creates serious threat stone f...

UNLABELLED This study was undertaken to determine the effects of collimators on the accuracy of preoperative sestamibi parathyroid imaging of the neck. METHODS Forty-nine patients with primary hyperparathyroidism underwent preoperative (99m)Tc-sestamibi parathyroid imaging. The protocol included early and late pinhole and parallel-hole imaging. One experienced nuclear physician, without knowl...

Shot peening is widely used to improve fatigue life of the metal component. It can also induce the distortion of thin component, which is called peen forming and is widely used for shaping aircraft wing skin. Shot peening surface coverage, intensity and saturation are important shot peening control parameters and have greatly influence on shot peening and peen forming results. Due to the insuff...

Shot peening has been developed to enhance the fatigue strength of metallic parts. However, improper shot peening can decrease the fatigue life due to induced high surface roughness and residual tensile stress. The effectiveness of the manual shot peening process is accomplished by the control of the process parameters to provide a uniform intensity and coverage throughout the work piece. This ...

We present a neural network based approach to key frame extraction in the compressed domain. The proposed method is an amalgamation of both the MPEG-7 descriptors namely motion intensity descriptor and spatial activity descriptor. Shot boundary detection and block motion estimation techniques are employed prior to the extraction of the descriptors. The motion intensity (“pace of action”) is obt...
