Although Josephson junctions can be viewed as highly nonlinear impedances for superconducting quantum technologies, they also possess internal dynamics that may strongly affect their behavior. Here, we construct a computational framework that includes a microscopic description of the junction (full fledged treatment of both the superconducting condensate and the quasiparticles) in the presence of a surrounding electrical circuit. Our approach generalizes the standard resistor capacitor Josephson model to arbitrary junctions (including, e.

Limited experience is available for older patients. We present a retrospective analysis of 73 consecutive patients aged over 65 years treated for aggressive or relapsed lymphoma by HDT with carmustine, etoposide, cytarabine and melphalan (BEAM) at full dosage followed by ASCT.

We have studied the effects of chronic sepsis in rats with special consideration to contractile and neuromuscular blockade properties in relation with the level of messenger RNA (mRNA) coding for ryanodine and acetylcholine receptors.
Design: This was an experimental animal study.
Critical illness polyneuromyopathy (CIP) leads to major muscle weakness correlated with peripheral nerve and/or muscle alterations. Because sepsis seems to be the main factor, we used an experimental model of chronic sepsis in rats to study the localization of the first alterations on isolated motor units of soleus muscle. Seven days of chronic sepsis leads to a decrease in muscle force and an increase in muscle fatigability.
