  • SKIING the SUN New Mexico Essays by Michael Waterman
    SKIING THE SUN New Mexico Essays ——————————————————— by Michael Waterman ....he will eat dried buffalo meat and frijoles with chili, and he will be glad to drink water when he can get it. From the novel Death Comes for the Archbishop, written by Willa Cather in 1926-1927. In recent years I have written several essays about New Mexico, only one of which has appeared in print. The truth is that my motivation has not been to tell others these stories and thoughts, but instead to articulate them to myself. That is harder than it looks, at least it is when I do it! After the memorial article about Gian-Carlo Rota appeared in the Notices of the AMS (here it is titled “Silhouettes on the Mesa”), several people expressed an interest in Rota, Ulam and Metropolis, so I decided to post this material. As this appears on my scientific web page, I have only included the essays that relate to science and mathematics, or more accurately, to scientists and mathematicians. The only formulas in the manuscript appear in “Silhouettes” and should be easy to skip over. The title comes from a 1970s slogan advertising New Mexico, “Ski the Sun,” that referred to the fact that the New Mexico weather was so good that people didn’t need to ski in bad weather. Coming from Idaho where there wasn’t much sunshine in the winter, I was struck by the reluctance of people to venture outdoors in anything but ideal conditions. Then again there is an obvious connection to be made with that incredible ball of fire when the bomb exploded at White Sands on July 16, 1945.

  • Professor Michael Waterman
    City University Distinguished Lecture Series Speaker Professor Michael Waterman University Professor at University of Southern California Mathematical and Statistical Problems from DNA Sequencing Distinguished Lecture Series on Monday, 8 September 2014 at 10:30 am at Connie Fan Multi-media Conference Room 4/F Cheng Yick-chi Building City University of Hong Kong Tat Chee Avenue, Kowloon Abstract The ability to produce DNA sequence has dramatically increased since the 2001 announcement of the human genome sequence. This lecture will survey a few of the algorithmic and statistical issues in this area. The volume of raw sequence reads from which genomes must be estimated has caused a shift from the computational methods used in the Human Genome Project. Those methods have been used and improved since the mid 1970s. A new approach reduced computation time, but required much more memory. This result brought about new memory reduction techniques. At the same time, traditional sequence comparison methods used since the early 1970s have in part been replaced by so-called alignment-free methods. Biography Professor Michael Waterman holds an Endowed Associates Chair at USC. He came to University of Southern California (USC) in 1982 after positions at Los Alamos National Laboratory and Idaho State University. He has a bachelor’s degree in Mathematics from Oregon State University, and a PhD in Statistics and Probability is from Michigan State University. He has held visiting positions at the University of Hawaii (1979–80), the University of California at San Francisco (1982), Mt. Sinai Medical School (1988), Chalmers University (2000), and in 2000–2001 he held the Aisenstadt Chair at University of Montreal.

  • Fluctuations of the Longest Common Subsequence in the Asymmetric
    FLUCTUATIONS OF THE LONGEST COMMON SUBSEQUENCE IN THE ASYMMETRIC CASE OF 2- AND 3-LETTER ALPHABETS Federico Bonetto∗ and Heinrich Matzinger† October 10, 2018 Abstract We investigate the asymptotic standard deviation of the Longest Common Sub- sequence (LCS) of two independent i.i.d. sequences of length n. The first sequence is drawn from a three letter alphabet 0, 1, a , whilst the second sequence is binary. { } The main result of this article is that in this asymmetric case, the standard devia- tion of the length of the LCS is of order √n. This confirms Waterman’s conjecture [22] for this special case. Our result seems to indicate that in many other situations the order of the standard deviation is also √n. 1 Introduction In computational genetics and computational linguistics one of the basic problem is to find an optimal alignment between two given sequences X := X1 ...Xn and Y := Y1 ...Yn. This requires a scoring system which can rank the alignments. Typically a substitution matrix gives the score for each possible pair of letters. The total score of an alignment is the sum of terms for each aligned pair of residues, plus a usually negative term for each gap (gap penalty). arXiv:math/0410404v1 [math.CO] 18 Oct 2004 Let us look at an example. Take the sequences X and Y to be binary sequences. Let the substitution matrix be equal to: 0 1 0 2 1 1 1 3 With the above matrix we get the following scores for pairs of letter: s(0, 0)=2,s(0, 1) = s(1, 0)=1,s(1, 1)=3.
