Convergence of the regularized short pulse equation to the short pulse one

We consider the regularized short-pulse equation, which contains nonlinear dis- persive effects. We prove that as the diffusion parameter tends to zero, the solutions of the dispersive equation converge to discontinuous weak solutions of the short-pulse one. The proof relies on deriving suitable a priori estimates together with an application of the compensated compactness method in the Lp setting

Multiple breaks in lending rate pass-through A cross country study for the euro area

A new approach is proposed for searching multiple unknown breaks, possibly associated with EMU, in the short term business lending rate pass-through. Multiple breaks are detected in five out of nine countries of the euro area. The last break occurs much before the start of EMU for France, several months after that event for Austria, Italy and Germany. Long run pass-throughs decrease (except for France) sizably below one (except for the Netherlands); heterogeneity in the monetary transmission increases across countries. These results raise doubts on claims of a more effective monetary policy under EMU.Interest rates; Monetary policy; Economic and Monetary Union; Cointegration analysis; Structural breaks

Convergence of the Ostrovsky equation to the Ostrovsky-Hunter one

We prove that as the diffusion parameter tend to zero, the solutions of the dispersive equation converge to discontinuous weak solutions of the Ostrovsky-Hunter equation.

Oleinik type estimates for the Ostrovsky-Hunter eequation

The Ostrovsky-Hunter equation provides a model for small-amplitude long waves in a rotating fluid of finite depth. It is a nonlinear evolution equation. In this paper we study the well-posedness for the Cauchy problem associated to this equation within a class of bounded discontinuous solutions. We show that we can replace the Kruzkov-type entropy inequalities by an Oleinik-type estimate and prove uniqueness via a nonlocal adjoint problem. An implication is that a shock wave in an entropy weak solution to the Ostrovsky-Hunter equation is admissible only if it jumps down in value (like the inviscid Burgers equation)

Wellposedness results for the short pulse equation

The short pulse equation provides a model for the propagation of ultra-short light pulses in silica optical fibers. It is a nonlinear evolution equation. In this paper the wellposedness of bounded solutions for the homogeneous initial boundary value problem and the Cauchy problem associated to this equation are studied.Comment: arXiv admin note: text overlap with arXiv:1310.701

A less effective monetary transmission in the wake of EMU? Evidence from lending rates pass-through

A new approach to search for structural breaks in the retail lending rates pass-through in the wake of EMU is proposed and implemented for Italy and Portugal. The econometric exercise shows that breakpoints cluster in the second semester 1999 and that the pass-through on short term lending is, in contrast with earlier research, sizeably lower in the post-break period. The recently proposed distinction between monetary policy and cost-of-funds approaches in the pass-through analysis does not yield different breakpoints. These results challenge the widely held view that EMU has in its wake enhanced the effectiveness of monetary transmission via the banking sector and made it more uniform across countries, because of rising and converging pass-throughs. A strengthened relationship lending could at least partly explain the reduced pass-through in the Italian case.Interest rates; Monetary policy; European Monetary Union; Relationship lending; Cointegration analysis; Structural breaks

Well-posedness result for the Kuramoto–Velarde equation

AbstractThe Kuramoto–Velarde equation describes slow space-time variations of disturbances at interfaces, diffusion–reaction fronts and plasma instability fronts. It also describes Benard–Marangoni cells that occur when there is large surface tension on the interface in a microgravity environment. Under appropriate assumption on the initial data, of the time T, and the coefficients of such equation, we prove the well-posedness of the classical solutions for the Cauchy problem, associated with this equation

Peripartum patient with epigastric pain

A 44-year-old female, gravida 2, para 1, abortus 1, presented to the emergency department with epigastric pain, vomiting and nosebleed at 36 weeks gestation. She had right upper quadrant tenderness and was hypertensive at 138/90 mmHg. Laboratory studies demonstrated decreased platelets of 122 k/mcL, Hb of 11.2 g/dL and RBC of 3.48 M/mcL, elevated AST of 371 U/L and ALT of 522 U/L, and proteinuria of 13 mg/dL
