Solutions of Fixed Period in the Nonlinear Wave Equation on Networks
(Birkhauser Verlag AG, 2019-06-15)The wave equation on network is defined by ∂_{tt}u=Δ_{G}u+g(u), where u∊ℝⁿ and the graph Laplacian Δ_G is an operator on functions on n vertices. We suppose that g:ℝⁿ→ℝⁿ is an odd continuous function that satisfies g(0)=0, ... -
Altered Amygdala Connectivity in Individuals with Chronic Traumatic Brain Injury and Comorbid Depressive Symptoms
Depression is one of the most common psychiatric conditions in individuals with chronic traumatic brain injury (TBI). Though depression has detrimental effects in TBI and network dysfunction is a "hallmark" of TBI and ... -
Stabilization in a State-Dependent Model of Turning Processes
(SIAM, 2012-01-03)We consider a two-degree-of-freedom model for turning processes which involves a system of differential equations with state-dependent delay. Depending on process parameters (e.g., spindle speed, depth of cut) the cutting ... -
Global Stability Lobes of Turning Processes with State-Dependent Delay
(SIAM, 2012-09-13)We obtain global stability lobes of two models of turning processes with inherit nonsmoothness due to the presence of state-dependent delays. In the process, we transform the models with state-dependent delays into systems ...
