Stellar Disk Evolution and Gaseous Disk Turbulence of Dwarf Irregular Galaxies

by Hong-Xin Zhang

This book focuses on the stellar disk evolution and gas disk turbulence of the most numerous galaxies in the local Universe - the dwarf galaxies. The "outside-in" disk shrinking mode was established for a relatively large sample of dwarf galaxies for the first time, and this is in contrast to the "inside-out" disk growth mode found for spiral galaxies. Double exponential brightness profiles also correspond to double exponential stellar mass profiles for dwarf galaxies, which is again different from most spiral galaxies. The cool gas distribution in dwarf galaxies was probed with the spatial power spectra of hydrogen iodide (HI) gas emission, and provided indirect evidence that inner disks of dwarf galaxies have proportionally more cool gas than outer disks. The finding that no correlation exists between gas power spectral indices and star formation gave important constraints on the relation between turbulence and star formation in dwarf galaxies.

Emerging Concepts of Tumor Exosome–Mediated Cell-Cell Communication

by Huang-Ge Zhang

In multicellular organisms, communication between cells involves secretion of proteins that bind to receptors on neighboring cells. While this has been well documented, another mode of intercellular communication has recently become the subject of increasing interest: the release of exosomes. In cancer, tumor exosomes are involved in various aspects of pathogenesis, including proliferation, immunosuppression, and metastasis. Given the ability of exosomes to export unneeded endogenous molecules from cells, these structures hold great potential as anticancer therapeutic agents. They are also being studied as prognostic markers for cancer.

Contract Theory in Continuous-Time Models (Springer Finance)

by Jianfeng Zhang Jakša Cvitanic

In recent years there has been a significant increase of interest in continuous-time Principal-Agent models, or contract theory, and their applications. Continuous-time models provide a powerful and elegant framework for solving stochastic optimization problems of finding the optimal contracts between two parties, under various assumptions on the information they have access to, and the effect they have on the underlying "profit/loss" values. This monograph surveys recent results of the theory in a systematic way, using the approach of the so-called Stochastic Maximum Principle, in models driven by Brownian Motion. Optimal contracts are characterized via a system of Forward-Backward Stochastic Differential Equations. In a number of interesting special cases these can be solved explicitly, enabling derivation of many qualitative economic conclusions.
