Another version of programming ‘The Tower of Hanoi’ in TEX is provided. No nodding knowledge of Lisp is required; just plain TEX. There is no restriction on the number of disks, apart from the installed limits of TEX. Generalized disks can be moved as well.

BACKGROUND Motexafin lutetium (Lu-Tex) is a photosensitizer that targets atheromatous plaque. Subsequent photoactivation (photodynamic therapy [PDT]) induces local cytotoxic effects. The aim of the present study was to investigate whether Lu-Tex targets vein graft intimal hyperplasia and whether subsequent photoactivation attenuates the disease process. METHODS AND RESULTS The subcellular loc...

Levels of carcinoembryonic antigen (CEA) and a tumor-extracted CEA-related antigen (TEX) were determined in sera from patients with carcinomas of the breast, colon, lung, head and neck, and a number of miscellaneous categories. The purpose of this study was to compare the levels of each antigen at various stages of malignant disease. Competitive radioimmunoassays developed in our laboratory wer...

TEX has lasted longer than many other computer software technologies. This article reviews some of the history of TEX and METAFONT, how they have come to be used in practice, and what their impact has been on document markup, the Internet, and publishing. TEX has several design deficiencies that limit its use and its audience. We look at what TEX did right, and with 25 years of hindsight, what ...

We present a new strategy for conversion between TEX mathematical expressions and MathML. Previous efforts have attempted either superficial high level transliteration or full execution of TEX. We observe that document markup typically uses macros that relate to semantics, and show how this structure can be exploited in the translation process. We present the overall architecture of two impleme...

While TEX is unanimously praised for its typesetting capabilities, it is also regularly blamed for its poor programmatic offerings. A macro-expansion system is indeed far from the best choice in terms of generalpurpose programming. Several solutions have been proposed to modernize TEX on the programming side. All of them currently involve a heterogeneous approach in which TEX is mixed with a fu...

A brief introduction to the א project, a TEX extension providing most of Ω and ε-TEX features.

TEX and METAFONT, translated into JAVA and compiled with TYA, a publicdomain JIT compiler, run about 10 times more slowly than the same programs in C (without TYA, they are 20 times slower). A year ago, they ran 50 times more slowly. In a year’s time, perhaps using Sun’s new JIT compiler, it is reasonable to assume that the factor will be down to 2 or 3. At that point—bearing in mind the speed ...
