Follow-up ranged from 2 years to 60 years. First symptoms occurred before age 2 in 90% of patients. Main clinical features were fever (100%), abdominal pain (92%), diarrhea (88%), enlarged lymph nodes (88%), skin rash (86%), arthralgias (85%), arthritis (43%), growth delay (33%), CNS white matter involvement (7,5%) and macrophage activation syndrome (5%). We recorded 3 disease-related deaths. I...

E-mail addresses: [email protected], [email protected] The simplicity of interpreting depth profiling in SIMS experiments is often limited by sample damage and surface roughness that accompany the ion bombardment process. Molecular dynamics simulations are implemented to obt...

Ab initio G3(MP2,CC)//B3LYP/6-311G calculations have been performed to investigate the C2H + C6H6 and C4H3 + C4H4 reactions on the C8H7 potential energy surface. The results demonstrate that C2H reacts with benzene without ...

It is an unfortunate fact of academic life that there is a sharp divide between science and philosophy, with scientists often being openly dismissive of philosophy, and philosophers being equally contemptuous of the naiveté of scientists when it comes to the philosophical underpinnings of their own discipline. In this paper I explore the possibility of reducing the distance between the two side...

Assuming that, given the processes of technology diffusion, adolescent behavior forecasts future consumption of digital information, it would seem pertinent to study the characteristics of teenager technology use. This research asks: What are the key patterns regarding the use of technology platforms by teenagers? Is technology usage among teenagers shaped by schools' disparate teaching philoso...

Today we examine the zig-zag product introduced by Reingold, Vadhan, and Wigder­ son [2] and Capalbo, Reingold, Vadhan, and Wigderson [1]. The product leads to a remarkable constructioon of expander graphs needed in the Spiser-Spielman code. In addition, their works introduce a probabilistic viewpoint of expansion. In previous liter­ ature, the spectral techniques are used to analyze the expans...
