Introduction and Background: Radial grabens at Tharsis record crustal extension due to the load [1−3]. However their development and significance beyond 2-D strain estimates are largely unknown. For example, early Viking-based strain models required two separate phases of Tharsis loading to produce the “inner” and “outer” radial grabens [4,5]. In contrast, recent MGS-based stress models for Tha...

There is some evidence that college student drinkers may continue drinking in the face of adverse consequences. We examined 2 hypotheses: (a) that this seemingly pathological behavior is a phenomenon of university life, occurring with consistency throughout the entirety of college, and (b) that individuals accumulate these consequences over multiple semesters in college. A sample of 3,720 stude...

This paper presents computable lower bounds of the penalty parameters for stable and convergent symmetric interior penalty Galerkin methods. In particular, we derive the explicit dependence of the coercivity constants with respect to the polynomial degree and the angles of the mesh elements. Numerical examples in all dimensions and for different polynomial degrees are presented. We show the num...

We propose a method to analyze the risk of blackouts with high penetration variable renewable energy sources (VRESs). consider model for long-term evolution power grid including propagation cascading failures, day-to-day fluctuations generation and moderate use storage. resilience stress as VRESs are progressively incorporated. also evaluate VRES performance average fraction daily demand covere...

We propose a simple modification to the differentiable penalty methods for solving nonlinear programming problems. This modification decreases the penalty parameter and the ill-conditioning of the penalty method and leads to a faster convergence to the optimal solution. We extend the modification to the augmented Lagrangian method and report some numerical results on several nonlinear programmi...

Several recent studies have shown a negative association between motherhood and wages. However, an analysis of change over time in the motherhood penalty has not been conducted. Using two cohorts of young women drawn from the 1975– 1985 National Longitudinal Survey of Young Women and the 1986–1998 National Longitudinal Survey of Youth, we explicitly test the relationship between motherhood and ...
