Siemes, C. (author), Ditmar, P. (author), Riva, E.M. (author), Slobbe, D.C. (author), Liu, X.L. (author), Farahani, H. (author)The Gravity Recovery and Climate Experiment (GRACE) satellite mission measures the Earth’s gravity field since March 2002. We propose a new filtering procedure for post-processing GRACE-based monthly gravity field solutions provided in the form of spherical harmonic coefficients. The procedure is tuned for the optimal estimation of linear trends...journal article 2012

Goodrich, C.P. (author), Dagois-Bohy, S. (author), Tighe, B.P. (author), Van Hecke, M. (author), Liu, A.J. (author), Nagel, S.R. (author)Athermal packings of soft repulsive spheres exhibit a sharp jamming transition in the thermodynamic limit. Upon further compression, various structural and mechanical properties display clean power-law behavior over many decades in pressure. As with any phase transition, the rounding of such behavior in finite systems close to the transition...journal article 2014

Liu, R. (author), Lühr, H. (author), Doornbos, E. (author), Ma, S.Y. (author)With the help of four years (2002–2005) of CHAMP accelerometer data we have investigated the dependence of low and mid latitude thermospheric density on the merging electric field, Em, during major magnetic storms. Altogether 30 intensive storm events (Dstmin <?100 nT) are chosen for a statistical study. In order to achieve a good correlation Em...journal article 2010

(author)Data assimilation (DA) holds considerable potential for improving hydrologic predictions as demonstrated in numerous research studies. However, advances in hydrologic DA research have not been adequately or timely implemented in operational forecast systems to improve the skill of forecasts for better informed real-world decision making. This is...journal article 2012

Liu, P. (author), Groves, R.M. (author), Benedictus, R. (author)Optical coherence elastography (OCE) has been applied to the study of microscopic deformation in biological tissue under compressive stress for more than a decade. In this paper, OCE has been extended for the first time, to the best of our knowledge, to deformation measurement in a glass fiber composite in the field of nondestructive testing. A...journal article 2014

Idema, T. (author), Liu, A.J. (author)Models that invoke nonlinear wavefront propagation in a chemically excitable medium are rife in the biological literature. Indeed, the idea that wavefront propagation can serve as a signaling mechanism has often been invoked to explain synchronization of developmental processes. In this paper we suggest a kind of signaling based not on diffusion...journal article 2014

Liu, L. (author), Zlatanova, S. (author)People often transport objects within indoor environments, who need enough space for the motion. In such cases, the accessibility of indoor spaces relies on the dimensions, which includes a person and her/his operated objects. This paper proposes a new approach to avoid obstacles and compute indoor paths with respect to the user dimension. The...journal article 2015
