Lingyan Shi, Robert R. Alfano, Min Xu, Cai Wei, Yang Pu, Wubao Wang, and James A. Eastham
Min Xu is a contributing author, "Chapter 10 Overview of the Cumulant Solution to Light Propagation Inside a Turbid Medium and Its Application" (with Cai Wei & Robert R. Alfano) and " Chapter 11 Deep Imaging of Prostate Cancer Using Diffusion Reconstruction of Banana Paths with Near Infrared Prostatoscope Analyzer" (with Yang Pu, Wubao Wang, James A. Eastham, and Robert R. Alfano).
Book description:
The use of light for probing and imaging biomedical media is promising for the development of safe, noninvasive, and inexpensive clinical imaging modalities with diagnostic ability. The advent of ultrafast lasers has enabled applications of nonlinear optical processes, which allow deeper imaging in biological tissues with higher spatial resolution. This book provides an overview of emerging novel optical imaging techniques, Gaussian beam optics, light scattering, nonlinear optics, and nonlinear optical tomography of tissues and cells. It consists of pioneering works that employ different linear and nonlinear optical imaging techniques for deep tissue imaging, including the new applications of single- and multiphoton excitation fluorescence, Raman scattering, resonance Raman spectroscopy, second harmonic generation, stimulated Raman scattering gain and loss, coherent anti-Stokes Raman spectroscopy, and near-infrared and mid-infrared supercontinuum spectroscopy. The book is a comprehensive reference of emerging deep tissue imaging techniques for researchers and students working in various disciplines.

Light Scattering Reviews, volume III
A. A. Kokhanovsky, Min Xu, and A. Katz
Min Xu is a contributing author (with A. Katz), “Statistical Interpretation of Light Anomalous Diffraction by Small Particles and its Applications in Bio-agent Detection and Monitoring”, p. 27-68.
Book description: This 3rd volume Light Scattering Reviews is devoted to modern knowledge and milestones in both experimental and theoretical techniques related to light scattering and radiative transport problems. It will consist of 3 parts comprising 11 contributions written by world leading experts in their respective fields. The general focus of the book will be on remote sensing of geophysical media. The first part will be devoted exclusively to studies of single light scattering by particles of different shapes and chemical compositions. The first chapter will review in situ measurements of cloud optical characteristics like cloud extinction and phase function, with the emphasis on ice clouds. Chapter 2 will cover opitcally soft particles common in marine environments and bio-suspensions while Chapter 3 will describe numerical techniques applicable not only to isotropic but also to chiral and anisotropic mdia. The final chapter in this part will deal with spatial symmetries in light scattering problems. This 3rd volume gives a valuable picture of recent developments in the areas of single light scattering, radiative transfer in particulate media and inverse problems of spherical atmospheres. It will further facilitate studies in light scattering media optics and be of importance for researchers across various scientific fields including astronomy, meteorology and geophysics. – Publisher description

Random Processes in Physics and Finance
Melvin Lax, Wei Cai, and Min Xu
This respected high-level text is aimed at students and professionals working on random processes in various areas, including physics and finance. The first author, Melvin Lax (1922-2002) was a distinguished Professor of Physics at City College of New York and a member of the U. S. National Academy of Sciences, and is widely known for his contributions to our understanding of random processes in physics. Most chapters of this book are outcomes of the class notes which Lax taught at the City University of New York from 1985 to 2001. The material is unique as it presents the theoretical framework of Lax's treatment of random processes, from basic probability theory to Fokker-Planck and Langevin Processes, and includes diverse applications, such as explanations of very narrow laser width, analytical solutions of the elastic Boltzmann transport equation, and a critical viewpoint of mathematics currently used in the world of finance. – Publisher description

GDH 2004: Proceedings of the Third International Symposium on the Gerasimov-drell-hearn Sum Rule And Its Extensions
Sebastian Kuhn, Jian-ping Chen, Angela Biselli, and CLAS Collaboration
Angela Biselli is a contributing author, "Spin asymmetries for exclusive and semi-exclusive reactions with CLAS."
Article abstract: An extensive experimental program to measure the spin structure of the nucleons is being carried out with the CLAS detector at Jefferson Lab using a longitudinally polarized electron beam incident on a longitudinally polarized target. Spin degrees of freedom offer new tools to explore the baryon structure and test the many theoretical approaches that attempt to characterize it, such as effective Lagrangian models and transverse momentum dependent parton distributions. I will present preliminary results for single and double spin asymmetries for exclusive π0, π+, and η electroproduction in the resonance region compared with unitary isobar and dynamical models, as well as ρ electroproduction for DIS kinematics. I will also report on an analysis of the semi-inclusive and exclusive channels where double and single spin asymmetries were used to study transverse momentum dependent parton distributions.

GDH 2002: Proceedings of the Second International Symposium on the Gerasimov-Drell-Hearn Sum Rule and the Spin Structure of the Nucleon
M. Anghinolfi, M. Battaglieri, R. De Vita, Angela Biselli, J. Kuhn, and CLAS Collaboration
Angela Biselli is a contributing author "STUDY OF THE Δ (1232) USING DOUBLE-POLARIZATION ASYMMETRIES."
Article abstract: An extensive experimental program to measure the spin structure of the nucleons is underway in Hall B at Jefferson Lab using a polarized electron beam incident on polarized hydrogen and deuterium targets, consisting of frozen NH3 and ND3 material. Spin degrees of freedom offer the possibility to test, in an independent way, existing models of resonance electroproduction. The most accessible resonance is the Δ(1232) since it does not overlap with other states and decays strongly via π emission. The present analysis select the Δ+(1232) in the exclusive channel from data of the EG1 run period, taken in the Fall of 1998, to extract single and double spin asymmetries in a Q2 range from 0.5 to 1.5 GeV2/c2. Results of the asymmetries are presented as a function of the center of mass decay angles of the π0 and compared with the unitary isobar model MAID, the dynamic model by Sato and Lee and the effective Lagrangian theory by Davidson and Mukhopadhyay.

GDH 2000 Proceedings of the Symposium of the Gerasimov-Drell-Hearn Sum Rule and the Nucleon Spin Structure in the Resonance Region
D. Dreschel, L. Tiator, Angela Biselli, R. Davidson, and P. Stoler
Angela Biselli is a contributing author, "Helicity structure of baryon resonances," pp.259-266.
Article abstract: The status of baryon resonance electroproduction at high momentum transfer is presented in the overall context of exclusive reactions. Alternate theoretical descriptions, including constituent quarks, generalized parton distributions, and PQCD are discussed as momentum transfers vary from small (large λ) to large (small λ) values. The role of helicity and polarization asymmetries is considered. The Δ(1232) is discussed as a test case. The future of the high Q2 program at Jefferson Lab in Halls C and B, as the beam energy increases to 12 GeV is also discussed.
