The Photoionized Accretion Disk in Her X-1 (2009)
Ji, L., Schulz, N., Nowak, M., Marshall, H. L., Kallman, T.
We present an analysis of several high-resolution Chandra grating observations of the X-ray binary pulsar Her X-1. With a total exposure of 170 ks, the observations are separated by years and cover...
Heating in an Extended Accretion Disk Corona along the Z-Pattern in Cyg X-2 (2008)
Schulz, N. S., Huenemoerder, D. P., Ji, L., Nowak, M., Yao, Y., Canizares, C. R.
We observed at very high spectral resolution the prototype Z-source Cyg x-2 twice along its entire X-ray spectral variation pattern. In this preliminary analysis we find an extended accretion disk...
Expressions are derived for the ensemble means and variances of the subsystem energies of built-up systems comprising two subsystems. The approach is based on the Statistical Energy Analysis of two...
LR design is introduced by the second author in his recent paper, and it plays a very important role in the construction of LKTS (a large set of disjoint Kirkman triple system). In this paper, we...
Further results on large sets of Kirkman triple systems, preprint (2008)
A Steiner triple system of order v (briefly STS(v)) consists of a v-element set X and a collection of 3element subsets of X, called blocks, such that every pair of distinct points in X is contained...
A construction for large sets of disjoint Kirkman triple systems (2008)
A Steiner system S(t, k, v) is a pair (X, B), where X is a velement set and B is a set of k-subset of X, called blocks with the property that every t-element subset of X is contained in a unique...
A new existence proof for large sets of disjoint Steiner (2008)
A Steiner triple system of order v (briefly STS(v)) consists of a v-element set X and a collection of 3-element subsets of X, called blocks, such that every pair of distinct points in X is contained...
Data-Driven Time-Parallelization in the AFM Simulation of Proteins (2008)
L. Ji, H. Nymeyer, A. Srinivasan, Y. Yu
Molecular Dynamics is a popular technique to simulate the behavior of physical systems, with resolution at the atomic scale. One of its limitations is that an enormous computational effort is...

Purification and Characterization of Soybean Root Nodule Ferric Leghemoglobin Reductase (1991)
Ji, L., Wood, Stephen, Becana Ausejo, Manuel, Klucas, R. V.
A ferric leghemoglobin reductase from the cytosol of soybean (Glycine max) root nodules was purified to homogeneity and partially characterized. The enzyme is a flavoprotein with flavin adenine...
