SYSTEMS OF HYPERBOLIC CONSERVATION LAWS WITH MEMORY [PDF]
Journal of Hyperbolic Differential Equations, 2007 Global weak solutions of bounded variation to systems of balance laws with non-local source are constructed by the method of vanishing viscosity. Suitable dissipativeness assumptions are imposed on the source terms to assure convergence of the method.

Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT The leading‐order asymptotic behavior of the solution of the Cauchy initial‐value problem for the Benjamin–Ono equation in L2(R)$L^2(\mathbb {R})$ is obtained explicitly for generic rational initial data u0$u_0$. An explicit asymptotic wave profile uZD(t,x;ε)$u^\mathrm{ZD}(t,x;\epsilon)$ is given, in terms of the branches of the multivalued ...

Planet-Disk Interaction revisited
EPJ Web of Conferences, 2013 We present results on our investigations of planet–disk interaction in protoplanetary disks. For the hydrodynamic simulations we use a second order semi–discrete total variation diminishing (TVD) scheme for systems of hyperbolic conservation laws on ...

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Although research on sustainability in the healthcare sector is growing, limited attention has been paid to how pharmaceutical companies can be motivated to engage more actively in achieving net‐zero healthcare goals. This study argues that the breadth of directors' experiences—across educational, industrial, and organizational domains—can ...

Journal of Control Science and Engineering, 2010 We study one class of nonlinear fluid dynamic models with impulse source terms. The model consists of a system of two hyperbolic conservation laws: a nonlinear conservation law for the goods density and a linear evolution equation for the processing rate.

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Corporate social responsibility (CSR) has increasingly been recognized as a strategic lever for enhancing organizational resilience. Although CSR literature is abundant, prior research has not fully explained how distinct CSR types, such as altruistic, promotional, and value‐creating, influence organizational resilience through sustainability ...

Tracking Climate and Environmental Attention: A News‐Based Composite Index
Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT This study introduces the Climate and Environmental Attention Index, a composite indicator that tracks media attention to climate and environmental issues. Based on the Semantic Brand Score, the proposed index extracts significant signals from unstructured text, going beyond traditional measures of word frequency and sentiment.

Hyperbolic conservation laws with relaxation [PDF]
Communications in Mathematical Physics, 1987 The effect of relaxation is important in many physical situations. It is present in the kinetic theory of gases, elasticity with memory, gas flow with thermo-non-equilibrium, water waves, etc. The governing equations often take the form of hyperbolic conservation laws with lower-order terms.

Numerical schemes for networks of hyperbolic conservation laws [PDF]
, 2014 In this paper we propose a procedure to extend classical numerical schemes for hyperbolic conservation laws to networks of hyperbolic conservation laws.
