Public health efforts to eliminate smoking from films accessible to youth have been countered by defenders of the status quo, who associate tobacco imagery in ‘‘classic’’ movies with artistry and nostalgia. The present work explores the mutually beneficial commercial collaborations between the tobacco companies and major motion picture studios from the late 1920s through the 1940s. Methods: Cigarette endorsement contracts with Hollywood stars and movie studios were obtained from internal tobacco industry documents at the University of California, San Francisco (UCSF) Legacy Tobacco Documents Library and the Jackler advertising collection at Stanford. Results: Cigarette advertising campaigns that included Hollywood endorsements appeared from 1927 to 1951, with major activity in 1931–2 and 1937–8 for American Tobacco Company’s Lucky Strike, and in the late 1940s for Liggett & Myers’ Chesterfield. Endorsement contracts and communication between American Tobacco and movie stars and studios explicitly reveal the cross- promotional value of the campaigns. American Tobacco paid movie stars who endorsed Lucky Strike cigarettes US$218 750 in 1937–8 (equivalent to US$3.2 million in 2008) for their testimonials. Conclusions: Hollywood endorsements in cigarette advertising afforded motion picture studios nationwide publicity supported by the tobacco industry’s multimillion US dollar advertising budgets.

Fowler Zerotrees of wavelet coefficients have shown a good adaptability for the compression of three-dimensional images. EZW, the original algorithm using zerotree, shows good performance and was successfully adapted to 3D image compression. This paper focuses on the adaptation of EZW for the compression of hyperspectral images. The subordinate pass is suppressed to remove the necessity to keep the significant pixels in memory. To compensate the loss due to this removal, signed binary digit representations are used to increase the efficiency of zerotrees. Contextual arithmetic coding with very limited contexts is also used. Finally, we show that this simplified version of 3D-EZW performs almost as well as the original one. Copyright © 2007 Emmanuel Christophe et al.

INTRODUCTION Since the publication of the Grossmann and Morlet paper [1], theory and applications concerning wavelets have im- proved. Theory on wavelets was progressively refined in sev- eral papers (e.g., [2, 3]). Originally, applications concerned mostly the data analysis field and more precisely in the time- scale analysis. However, their efficiency to represent complex signals with a limited number of generating func tions raised an interest for image coding [4]. Research in wavelet-based image coding began focusing on the search for the most efficient wavelet form to represent the data as in [4] together with the most efficient decompo- sition [5]. The quasiorthogonal 9/7 wavelet for lossy com- pression and the 5/3 wavelet for lossless compression with a multiresolution decomposition exhibit good results for a wide range of natural images. Thus, these specifications were adopted in the latest still image compression standard: JPEG 2000 [6]. Efficient techniques to code these wavelet coefficients were then defined. EZW successfully made use of the relation of wavelet coefficients in zerotrees [7], a technique which was further refined with SPIHT [8]. EBCOT, the coder for JPEG 2000 focuses on the neighborhood of each coefficient using contextual arithmetic coding [9]. In this standard, a total of 18 different contexts are used according to the value of neigh- boring coefficients. This paper looks at the zerotree-based compression tech- niques and improves them with the use of signed binary rep- resentations and arithmetic coding particularly in the con- text of 3D image encoding. The 3D images used here are hyperspectral images from the JPL/NASA airborne sensor AVIRIS. The same methods can be applied to medical images as magnetic resonance (MR) or computed tomography (CT) which are also formed of several slices. Hyperspectral image involves observing the same scene at different wavelengths (Figure 1).

This is a bibliography of signed graphs and related mathematics. Several kinds of labelled graph have been called “signed” yet are mathematically very different. I distinguish four types: • Group-signed graphs: the edge labels are elements of a 2-element group and are mul- tiplied around a polygon (or along any walk). Among the natural generalizations are larger groups and vertex signs. • Sign-colored graphs, in which the edges are labelled from a two-element set that is acted upon by the sign group: − interchanges labels, + leaves them unchanged. This is the kind of “signed graph” found in knot theory. The natural generalization is to more colors and more general groups—or no group. • Weighted graphs,inwhichtheedgelabelsaretheelements+1and−1oftheintegers or another additive domain. Weights behave like numbers, not signs; thus I regard work on weighted graphs as outside the scope of the bibliography—except (to some extent) when the author calls the weights “signs”. • Labelled graphs where the labels have no structure or properties but are called “signs” for any or no reason. Each of these categories has its own theory or theories, generally very different from the others, so in a logical sense the topic of this bibliography is an accident of terminology. However, narrow logic here leads us astray, for the study of true signed graphs, which arise in numerous areas of pure and applied mathematics, forms the great majority of the literature. Thus I regard as fundamental for the bibliography the notions of balance of a polygon (sign product equals +, the sign group identity) and the vertex-edge incidence matrix (whose column for a negative edge has two +1’s or two −1’s, for a positive edge one +1 and one −1, the rest being zero); this has led me to include work on gain graphs (where the edge labels are taken from any group) and “consistency” in vertex-signed graphs,and generalizable work on two-graphs (the set of unbalanced triangles of a signed complete graph) and on even and odd polygons and paths in graphs and digraphs. Nevertheless, it was not always easy to decide what belongs. I have employed the following principles: Only works with mathematical content are entered, except for a few representative purely applied papers and surveys. I do try to include: • Any (mathematical) work in which signed graphs are mentioned by name or signs are put on the edges of graphs, regardless of whether it makes essential use of signs. (However, due to lack of time and in order to maintain “balance” in the bibliography, I have included only a limited selection of items concerning binary clutters and postman theory, two-graphs, signed digraphs in qualitative matrix theory, and knot
