A model is developed for a non-uniform piezoelectric beam suitable for analyzing energy harvesting behavior. System dynamics are projected onto a numerically developed basis to produce energy functions which are used to derive equations of motion for the system. The resulting model reproduces the experimentally observed transition to chaos while providing a conservative estimate of power output...

We study the long-time behavior of conservative interacting particle systems in Z: the activated random walk model for reaction-diffusion systems and the stochastic sandpile. We prove that both systems undergo an absorbing-state phase transition. This preprint has the same numbering for sections, theorems, equations and figures as the published article “Invent. Math. 188 (2012): 127–150.”

Primary small cell carcinomas of the bladder are extremely rare tumors with an aggressive behavior. To date, no standard therapy has been proposed. There are some brief reports about the role of conservative surgery in patients not suitable for radical surgery. We report a case of a primary bladder small cell carcinoma treated with partial cystectomy.

background calcium infusion is used as a pre-treatment before calcium channel blockers to prevent hypotension. occasional cardioversion with calcium gluconate infusion is seen in patients with paroxysmal supraventricular tachycardia. several mechanisms have been suggested for mechanism. herein we report a case presenting with atrial fibrillation but cardioverted with calcium gluconate infusion,...

objectives: patients suffering from mild to moderate knee osteoarthritis may be treated with unloader knee orthoses or laterally wedged insoles. the aim of this study was to identify and compare the effects of two orthoses in these patients. methods: 56 patients with medial compartment knee oa were evaluated when wearing an unloader knee orthosis and insoles with a 6° lateral wedge which were r...
