Positive Polynomials, Convex Integral Polytopes, and a Random Walk Problem
Emanating from the theory of C*-algebras and actions of tori theoren, the problems discussed here are outgrowths of random walk problems on lattices. An AGL (d,Z)-invariant (which is a partially ordered commutative algebra) is obtained for lattice polytopes (compact convex polytopes in Euclidean space whose vertices lie in Zd), and certain algebraic properties of the algebra are related to geometric properties of the polytope. There are also strong connections with convex analysis, Choquet theory, and reflection groups. This book serves as both an introduction to and a research monograph on the many interconnections between these topics, that arise out of questions of the following type: Let f be a (Laurent) polynomial in several real variables, and let P be a (Laurent) polynomial with only positive coefficients; decide under what circumstances there exists an integer n such that Pnf itself also has only positive coefficients. It is intended to reach and be of interest to a general mathematical audience as well as specialists in the areas mentioned.

Modeling the Electrochemo-poromechanics of Ionic Polymer Metal Composites and Cell Clusters
This book presents a novel continuum finite deformation framework addressing the complex interactions among electrostatics, species transport, and mechanics in solid networks immersed in a fluid phase of solvent and ions. Grounded on cutting-edge multiphysics theories for soft active materials, the proposed model is primarily applied to ionic polymer metal composites (IPMCs). First, the influence of shear deformation on the IPMC response is analyzed through semi-analytical solutions obtained via the method of matched asymptotic expansions. Second, the novel electrochemo-poromechanical theory is used to predict the curvature relaxation and electric discharge that are observed in IPMC actuation and sensing, respectively, under a sustained stimulus. This newly formulated theory is, in turn, applied to biological cell clusters. Here, important mechanical considerations are integrated into classical bioelectrical models, thus offering novel insights into the interplay of mechanical and electrical signaling in the coordination of developmental processes.

Horace Walpole
An illuminating biographical study of the eighteenth-century English man of letters and patron of the artsHorace Walpole (1717–1797) was a collector, printer, novelist, arbiter of taste, and renowned writer of letters. In this book, eminent scholar Wilmarth Sheldon Lewis provides an unprecedented look at the life and work of one of England’s greatest men of letters. Lewis sheds light on Walpole’s relationships with his family and friends, his politics, his writings and printmaking activities, and his correspondence. Featuring portraits of Walpole, his relatives, and friends; images of Walpole's sketches and manuscripts; pages from books printed at Walpole’s Strawberry Hill Press; and views and plans of Strawberry Hill, the house, its rooms and furnishings, and its grounds, and accompanied by Lewis’s extensive annotations, this book provides an invaluable history of an extraordinary man.

Polychloroaromatic Compounds
The chlorination of aromatic and heteroaromatic compounds is one of the oldest and also one of the most important reactions since it heralded the rise of the heavy organic chemicals industry. Reports of polychlorobenzenes and polychloropyridines date back well into the last century and it is of historical interest that Kekule was probably the first to have prepared pentachloropyridine. Yet, in spite of the ancient lineage and the practical as well as theoretical significance of polychloroaromatics, there has existed so far no review exclusively devoted to their chemistry. Three inter national symposia on polychloro-chemistry since 1968, in which polychloroaromatics figured prominently in discussions amongst chemists and biologists, are evidence for the growing importance of this subject. Information on the chemistry and uses of the numerous polychloroaromatic compounds has remained buried largely in the journal and patent literature and only occasionally receives sparse and incidental treatment in an article primarily dealing with a specific ring system.
