Solvation Response Along the Reaction Coordinate in the Active Site of Ketosteroid Isomerase
Pseudomonas putida Coumarins Isomerases Spectrometry, Fluorescence Catalytic Domain Ketosteroids Biocatalysis Light Models, Molecular Equilenin
2016/5/25
A light-activated reaction analog has been developed to mimic the catalytic reaction cycle of Delta(5)-3-ketosteroid isomerase to probe the functionally relevant protein solvation response to the cata...
We consider “one-at-a-time” coordinate-wise descent algorithms for a class of convex optimization problems. An algorithm of this kind has been proposed for the L1-penalized regression (lasso) in the l...
Regularization Paths for Cox’s Proportional Hazards Model via Coordinate Descent
survival Cox model lasso elastic net
2015/8/21
We introduce a pathwise algorithm for the Cox proportional hazards model, regularized by convex combinations of `1 and `2 penalties (elastic net). Our algorithm fits via cyclical coordinate descent, a...
SparseNet:Coordinate Descent with Non-Convex Penalties
Sparse Regression Regularization Surface Non-convex Optimization Coordinate Descent Degrees of Freedom Variable Selection LASSO
2015/8/21
We address the problem of sparse selection in linear models. A number of non-convex penalties have been proposed in the literature for this purpose, along with a variety of convex-relaxation algorithm...
US GODAE:Global Ocean Prediction with the HYbrid Coordinate Ocean Model (HYCOM)
US GODAE Global Ocean Prediction HYbrid Coordinate Ocean Model
2015/7/3
During the past five to ten years, a broad partnership of institutions under NOPP sponsorship has collaborated in developing and demonstrating the performance and application of eddy-resolving, real-t...
A nonhydrostatic, isopycnal-coordinate ocean model for internal waves
Nonhydrostatic model Isopycnal coordinates Multi-layer model Internal waves Solitary waves Ocean modeling
2015/6/30
We present a nonhydrostatic ocean model with an isopycnal (density-following) vertical coordinate system. The primary motivation for the model is the proper treatment of nonhydrostatic dispersion and ...
An orthogonal terrain-following coordinate and its preliminary tests using 2-D idealized advection experiments
orthogonal terrain-following coordinate preliminary tests 2-D idealized advection experiments
2014/12/19
We have designed an orthogonal curvilinear terrain-following coordinate (the orthogonal σ coordinate, or the OS coordinate) to reduce the advection errors in the classic σ coordinate. First, we rotate...
Spatial Distribution of Seismicity: Relationships with Geomagnetic Z-Component in Geocentric Solar Magnetospheric Coordinate System
Earthquake Occurrence Earthquake Magnitude
2013/3/11
For 173477 epicenters of earthquakes with М ≥ 4.5, which occurred at the globe in 1973-2010, the geomagnetic Z-component in Geocentric Solar Magnetospheric (GSM) coordinate system were evaluated for t...
Which coordinate system for modelling path integration?
navigation geocentric egocentric allothetic idiothetic Neurons and Cognition
2012/5/2
Path integration is a navigation strategy widely observed in nature where an animal maintains a running estimate of its location during an excursion. Evidence suggests it is both ancient and ubiquitou...

2012/4/26
This paper is devoted to description of the relationship among oriented associativity equations, symmetry consistent conjugate curvilinear coordinate nets, and the widest associated class of semi- Ham...
