T o convert the energy of sunlight into chemical energy, the leaf splits water via the photosynthetic process to produce molecular oxygen and hydrogen, which is in a form of separated protons and electrons. The primary steps of natural photosynthesis involve the absorption of sunlight and its conversion into spatially separated electron hole pairs. The holes of this wireless current are capture...
We show that the manifold ∗RP#∗CP, which is homotopy equivalent but not homeomorphic to RP#CP, is in fact smoothable.
The global demand for cheap nuclear energy grows, and so do the risks of an accidental release of nuclear products into the environment. Therefore, understanding the health and ecological effects of contamination by radionuclides should be of greatest interest for biomedical specialists and the public. Empirical studies unequivocally show that high doses of ionizing radiation (IR) shift the red...
joined with a few teammates of mine from the debate squad and founded the Liberate the Chimps Society — the LTCS! Daniel J. Povinelli is Professor of Biology at the University of Louisiana at Lafayette. After studying as an undergraduate at the University of Massachusetts at Amherst, where he received his B.S. in Anthropology with a minor in Zoology (1986), he studied Physical Anthropology and ...
There is at least one undisputable universal related to music: in all the cultures that we know of, and throughout recorded history, people all around the world have engaged in music. Music has also been the focus of much study, placing it at the convergence of Art and Science. The aim of this session is to illustrate the current interdisciplinary investigations of music, combining the new appr...
The precise estimation of time and resource consumption plays a pivotal role in planning software development projects at their earliest development phase. Since cost parameters are mostly determined by the architecture, a possible approach is to design a platform independent architectural model of the prospective software and estimate the cost based on it. In this paper, we introduce a method,...
Explanations of human behavior are most often presented in a verbal form as theories. Psychologists can also harness the power and precision of mathematics by explaining behavior quantitatively. This chapter introduces the reader to how this is done and the advantages of doing so. It begins by contrasting mathematical modeling with hypothesis testing to highlight how the two methods of knowledg...
CLUSTER EXPANSION WITH APPLICATIONS 3 In order to guess the correct form of a, one should consider the left side of the equation above with a(y) ≡ 0. The integral may depend on x; a typical situation is that x is characterized by a length l(x), which is a positive number, so that the left side is roughly proportional to l(x). This suggests to try a(x) = cl(x), and one can then optimize on the v...
June 30, 1986 When Bouroncle and colleagues’ described hairy cell leukaemia as a distinct type of human leukaemia, the methodology for characterising the membrane phenotype of lymphocytes was not yet available. The peculiar morpholo~yofthe hairy cell with its long cytoplasmic villi, well demonstrated by phase contrast microscopy, had some resemblance with that of histiocytes as seen in tissue s...
