Fusion frames enable signal decompositions into weighted linear subspace components. For positive integers p, we introduce p-fusion frames, a sharpening of the notion of fusion frames. Tight p-fusion frames are closely related to the classical notions of designs and cubature formulas in Grassmann spaces and are analyzed with methods from harmonic analysis in the Grassmannians. We define the p-f...

A 65-year-old man in whom an inferior vena cava filter had been implanted for deep vein thrombosis was admitted to the cardiology department due to appetite loss and lumbago. Laboratory data showed increased total creatinine kinase (CK, 796 U/L, Picture 1, left) and CK-MB (1,213 U/ L), which exceeded the total CK value. Electrophoresis showed, in addition to an increase in CK-BB, a peak that mi...

The present experiment investigates the frame of reference involved in Visual-Auditory (VA) fusion over space. This multisensory phenomenon refers to the perception of unity (Welch & Warren, 1986) resulting from visual and auditory stimuli despite their potential spatial disparity. The extent of this illusion depends on the eccentricity in azimuth of the bimodal stimulus (Godfroy, Roumes, & Dau...

Pyoderma gangrenosum is a rare autoinflammatory syndrome manifested by skin lesions eventually creating ulcers. Surgical management can lead to scarring and contracture at the site of the lesion due to the pathergy phenomenon. A 43-year-old woman presented with a 5-year history of severe equinovarus deformity due to chronic pyoderma gangrenosum on her posteromedial ankle. She underwent a staged...

In this paper, a multi-scale image fusion method based on discrete wavelet frame (DWF) is proposed for merging a high-resolution panchromatic image and a low-resolution multispectral image. The downampling process is avoided by using discrete wavelet frame decomposition. It leads to translation invariant and is available for the image fusion. The lowfrequency part of the panchromatic image is d...

Solid bony fusion of large joints affected with active chronic infections, is still the most effective surgical solution to establish a useful function of the affected limb. Even with extensive peri-articular bone loss and severe deformities, arthrodesis in a functional position can provide effective stability. The reported fusion rates in such patients are not encouraging however, and secondar...
