Computer Graphics Forum, EarlyView.Abstract We introduce mixed super‐circles, a position‐curvature formulation of the original dynamic 2D super‐helix model. Compared to the latter, purely curvature‐based model – the so‐called chained formulation –, the mixed formulation that we propose here drastically reduces the algorithmic complexity of the solving scheme – from quadratic to quasi ...

Almost sure exponential stability of backward Euler–Maruyama discretizations for hybrid stochastic differential equations [PDF]
, 2011 This is a continuation of the first author's earlier paper [1] jointly with Pang and Deng, in which the authors established some sufficient conditions under which the Euler-Maruyama (EM) method can reproduce the almost sure exponential stability of the ...

The role of foreign capital flows in health finance
Economic Inquiry, EarlyView.Abstract This study develops an open economy version of the health deficit model to examine how rising health expenditures affect international capital flows, external balances, and welfare. The government issues bonds in international capital markets, linking health policy to international financial dynamics.

Bogomol’nyi-like equations in gravity theories
European Physical Journal C: Particles and FieldsUsing the Bogomol’nyi–Prasad–Sommerfield Lagrangian method, we show that gravity theory coupled to matter in various dimensions may possess Bogomol’nyi-like equations, which are first-order differential equations, satisfying the Einstein equations and ...

Monetary Policy When Preferences Are Quasi‐Hyperbolic
Journal of Money, Credit and Banking, EarlyView.Abstract We study discretionary monetary policy in an economy where economic agents have quasi‐hyperbolic discounting. We demonstrate that a benevolent central bank is able to keep inflation under control for a wide range of discount factors. If the central bank, however, does not adopt the household's time preferences and tries to discourage early ...

Variational C∞-symmetries and Euler–Lagrange equations
, 2006 A generalization of the concept of variational symmetry, based on λ-prolongations, allows us to construct new methods of reduction for Euler–Lagrange equations. An adapted formulation of the Noether's theorem for the new class of symmetries is presented.

On the relation between the Feynman paradox and the Aharonov–Bohm effects
New Journal of Physics, 2012 The magnetic Aharonov–Bohm (A–B) effect occurs when a point charge interacts with a line of magnetic flux, while its reciprocal, the Aharonov–Casher (A–C) effect, occurs when a magnetic moment interacts with a line of charge.

Monetary and Macroprudential Policies under Dollar‐Denominated Foreign Debt
Journal of Money, Credit and Banking, EarlyView.Abstract This paper studies monetary and macroprudential policies in a small open economy that borrows from abroad in foreign currency. The model features a novel mechanism in which exchange rate depreciation triggered by a borrowing constraint is amplified through balance of payments adjustments, increasing the real burden of foreign debt and causing ...

PART I – USUAL PROBLEMS OF OPTIMIZING THE ACTION SYSTEMS OFTHE BAND TRANSPORTERS [PDF]
Fiabilitate şi Durabilitate, 2012 Most of the systems of electric action are non-linear systems, including the continuous transportsystems with band, that could be brought by linearization and negligence at the linear system.

Policy Biases in a Model with Labor‐Market Frictions
Journal of Money, Credit and Banking, EarlyView.Abstract We develop a model with labor‐market matching frictions that is subject to a range of shocks, including shocks to matching efficiency and bargaining power, and use the model to examine how monetary policy should respond to such shocks. We show that optimal monetary policy responds effectively to these shocks, producing economic outcomes that ...
