Substantial differences in source contributions to carbon emissions and health damage necessitate balanced synergistic control plans in China
China’s strategy to concurrently address climate change and air pollution mitigation is hindered by a lack of comprehensive information on source...

Heterogeneous changes in global glacial lakes under coupled climate warming and glacier thinning
Global glacial lakes have expanded markedly in recent decades, accompanied by many catastrophic glacial lake outburst floods. However, our...

Orbit Dynamics, Stability and Chaos in Planetary Systems
Let us start with a problem of dynamical biology, which was posed about 800 years ago by Fibonacci1

Collision Free Motion Planning on Graphs
A topological theory initiated in [4,5] uses methods of algebraic topology to estimate numerically the character of instabilities arising in motion...

Computing Protein Structures from Electron Density Maps: The Missing Fragment Problem
Rapid protein structure determination relies greatly on the availability of software that can automatically generate a protein model from an...

Planet Formation
Motivating the study of planet formation is not difficult for any curious audience. One of the fundamental human questions is that of origins: “where...

Pareto Optimal Coordination on Roadmaps
Given a collection of robots sharing a common environment, assume that each possesses an individual roadmap for its C-space and a cost function for...

Coordinating Multiple Droplets in Planar Array Digital Microfluidics System
This paper presents an approach to coordinate the motions of droplets in digital microfluidic systems used for biochemical analysis. A digital...

Semi-Differential Invariants for Recognition of Albebraic Curves
This paper studies the recognition of low-degree polynomial curves based on minimal tactile data. Differential and semi-differential invariants have...

Computing Deform Closure Grasps
In prior work, we extended the well-known form closure grasp framework for rigid parts to a class of deformable parts, modeled as frictionless...

Applications of the Correlation Length
The correlation length is the system–dependent parameter, which defines the structure of the dominant current–carrying (electric or fluid) paths....

Pressure Saturation Curves and the Critical Volume Fraction for Percolation
The pressure-saturation curves of porous media give fundamental information about the pore space. In equilibrium, ignoring effects due to hysteresis,...

Effects of Multi-Scale Heterogeneity
It is generally agreed that problems with multi-scale heterogeneity present the biggest challenge to computation and understanding. A few such...

Uniform Coverage of Simple Surfaces Embedded in $\mathbb{R}^3$ for Auto-Body Painting
We develop a procedure for automated trajectory generation for robotic spray painting applications. Painting requires that the spray gun deposit...

Sampling-Based Motion Planning under Kinematic Loop-Closure Constraints
Kinematic loop-closure constraints significantly increase the difficulty of motion planning for articulated mechanisms. Configurations of...

Small-Scale Mantle Plumes: Imaging and Geodynamic Aspects
Columnar, upwelling masses of hot rock in the Earth’s mantle, called mantle plumes, are spectacular features of our planet because they supply the...

A Combined Geophysical/Engineering Approach for the Seismic Safety of Long-Span Bridges
The spatial distribution of the resonance frequency of the sedimentary cover in the Cologne area was estimated by the horizontal-to-vertical spectral...

An Earthquake Early Warning System for the Romanian Capital
Although earthquake early warning systems have inherently short warning times between seconds and a minute they become increasingly important as part...

Nonlinear Seismology - The Seismology of the XXI Century
Nonlinear effects in ground motion during large earthquakes have been a long controversial issue between seismologists and geotechnical engineers....

The Dead Sea Fault and Its Effect on Civilization
The Dead Sea fault (DSF) is the most impressive tectonic feature in the Middle East. It is a plate boundary, which transfers sea floor spreading in...
