The development of the axial skeleton is a complex process, consisting of segmentation and differentiation of somites and ossification of the vertebrae. The autosomal recessive skeletal fusion with sterility (sks) mutation of the mouse causes skeletal malformations due to fusion of the vertebrae and ribs, but the underlying defects of vertebral formation during embryonic development have not ye...

[1] Between 105–115 degrees, the SKS waveform is complicated by the formation of SPdKS, a wave that has segments of P diffraction along the core mantle boundary. While previous studies have primarily focused on the moveout of SPdKS from SKS, we analyze the concomitant reduction of the SKS amplitude. Long-period SKKS/SKS amplitude ratios present a coherent global pattern. SKKS/ SKS is relatively...

BACKGROUND Seborrheic keratoses (SKs) are common skin lesions that have been shown to occur with increasing age, although the age of onset is not well recorded. OBJECTIVE To determine the prevalence, nature, and distribution of SKs in young people. METHODS One hundred seventy people aged 15 to 30 years were given a total body examination during which the presence, number, site, and size of ...

This paper shows how derivations in (a variation of) SKS can be translated into proof nets. Since an SKS derivation contains more information about a proof than the corresponding proof net, we observe a loss of information which can be understood as “eliminating bureaucracy”. Technically this is achieved by cut reduction on proof nets. As an intermediate step between the two extremes, SKS deriv...

Seborrhoeic keratoses (SKs) are common benign epithelial tumors. They preferentially arise on seborrheic skin areas such as the face and the trunk, rarely on the genital area. We report the case of a 41-year old patient with no particular past medical history presenting with pubic lesions evolving for three years. Clinical examination showed blackish keratosis lesions having a cerebriform appea...

This paper shows how derivations in the deep inference system SKS for classical propositional logic can be translated into proof nets. Since an SKS derivation contains more information about a proof than the corresponding proof net, we observe a loss of information which can be understood as “eliminating bureaucracy”. Technically this is achieved by cut reduction on proof nets. As an intermedia...
