The most common screening techniques to diagnose a patient’s illness are blood collection and intravenous procedures. To find or injection site, conventional support tools, such as latex tubing buckle-type tourniquets, generally used compress the vessels. This passive method has significant problems allergy, vulnerability site contamination potential bloodstream infection, physical damage due i...

Here we describe the metathesis reactions of a strained eight-membered ring that contains both alkene and alkyne functionality. We find that the alkyne metathesis catalyst produces polymer through a ring-opening alkyne metathesis reaction that is driven by the strain release from the monomer. The strained monomer provides unusual reactivity with ruthenium-based alkene metathesis catalysts. We i...

Urinary bladder rhabdomyosarcoma from a 9-month-old female Labrador retriever dog is described. Grossly reddish black multiple friable multinodular masses filled the lumen of the urinary bladder. Histologically, the masses consisted of round, fusiform and polygonal cells with various consistencies. There were also some strap-like cells with chained nuclei and cross-striations. It was diagnosed ...

A substantial proportion of patients develop proximal junctional kyphosis following spinal surgery. To combat this postoperative change, several techniques have focused on maintaining the structural integrity of adjacent spinal levels and adapting the proximal end of the fusion construct to accommodate the increased mechanical stressors produced by long spinal fusion. The use of Mersilene tape ...

Contraction theory is a recently developed control system tool based on an exact differential analysis of convergence. After establishing new combination properties of contracting systems, this paper derives new controller and observer designs for mechanical systems such as aircraft and underwater vehicles. The classical nonlinear strap down algorithm is also shown to be marginally contracting....
