He received his Bachelor of Arts with a major in mathematics from Brown University in 1958. Just prior to the start of his junior year Jay broke his neck resulting in him becoming a hemiplegic. After , he studied at the Courant Institute of Mathematical Sciences [NYU] where, in 1963 he earned a Masters and Ph.D. in applied mathematics. A year earlier, he co-published an article, Circle Supports the Largest Sand Pile, solving a problem in the theory of plasticity. Next he went on with a Fulbright Scholarship to the University of Italy at Pisa where he was asked to teach a numerical analysis course in Italian. From 1965 to 1978 he was at the University of Minnesota, initially in their Mathematics Department and then as an Associate Professor in their Computer Science Department when it was created. While at the University of Minnesota his work involved supersonic flows and shock waves, non-linear boundary value problems, Chrono-biology, linguistics, computer art and software for a virtual memory machine. He designed a deformable canvas which was used by Jay’s 1st wife, Ruth who used it to produce paintings, prints, sculpture and videos. His virtual memory machine was implemented for a professor of their Department of Economics. It was employed to analyze the Crisp Tapes in their entirety. Until then only subsets of this data base of all trades of the stock exchange had been analyzed. This was at the time just before the 1st commercially available virtual memory machines became available.Starting in 1973 with the initial passage of Section 504 of the Americans with Disabilities Act, Jay became active as an advocate for the disabled. In 1978 he moved to the State University at Buffalo as Director of Academic Computing. There he married his 2nd wife, Virginia in 1982. Jay, also, served on several New York Governor Mario Cuomo’s commissions for the Disabled, was President of the New York State Coalition for Persons with Disabilities, served on the Erie County Commission for the disabled and was a member of the board of directors of the WNY Independent Living Center since its inception. Before there was the World Wide Web he created and maintained the Cornucopia of Disability Information. Once it was featured in Computing for Dummies.One of the NY Governor's commissions was charged to assist inventors to bring their products for the disabled to market. A grant went to an inventor whose goal was to employ alpha brainwaves to control a computer. During this period Jay was a consultant to the Sarah project. Sarah, at age 4, contracted spinal meningitis resulting in paralysis from the waist down. The project's aim was to build a big wheels tricycle that she could operate with electrical stimulators. At the same time an electronic leg brace was designed for Jay using the same principles. Neither solution employed a computer. Sarah could get on her tricycle herself, velcro her feet to the pedals and attach her electrodes. Then she could scoot off. Beyond the medical benefits she and her mother would enjoy greater independence and freedom for social activities. Jay used his electronic leg brace for many years until it no longer could be repaired.He stepped down as Director of Academic Computing in the 1990s and retired in 1998. He moved to North Carolina with Virginia’s horses, dogs and pussy cats. He had spinal surgery at the start of 2001 that, unfortunately, left him almost fully paralyzed. In his mid-70s he passed the FINRA Series 65 exam on his 1st try. As an octogenarian he created and published numeric tools for market analysts. In addition, during 2017 and 2018 he published 3 articles demonstrating how his tools can be applied to different areas of trading. One dealt with stock optionsedit

Two indicators along with an associated probability function are introduced to enhance the arsenal of traders' tools. The Hull Moving Average as described by its creator, Alan Hull, is the fastest of all moving averages. Its construction is built from weighted moving averages. The new indicators, although not moving averages, behave similarly, and are not only faster than the Hull, but forecast market behavior a few bars. The probability function sharply identifies turns in the market. These tools are constructed employing linear regression. Applied to the weekly SPX data, from late 2008 thru 2015, The Leavitt Convolution appears 3 weekly bars faster than the Hull.

This work is a preliminary study of methods to quantify alliteration. Ten pieces made up of poetry and prose (literary and non-literary) were used to create test sets. Three forms of each test set were examined: texts transcribed in IPA notational equivalent, in Chomsky and Halle features, and in Fromkin and Rodman features. Tests included the deletion of vowels, the weighting of the initial sounds, and the weighting of types according to their frequency in the population of the set. The various configurations were analyzed using a gap-recurrence method. Rankings were obtained by combining measures both of high frequency and of clustering properties. The resulting rankings compare not unfavorably with an intuitive ranking.
