Obituary: Amir Pnueli, 1941–2009 Krzysztof R. Apt and Lenore D. Zuck
Obituary: Amir Pnueli, 1941–2009 Krzysztof R. Apt and Lenore D. Zuck Amir Pnueli was born in Nahalal, Israel, on April 22, 1941 and passed away in New York City on November 2, 2009 as a result of a brain hemorrhage. Amir founded the computer science department in Tel-Aviv University in 1973. In 1981 he joined the department of mathematical sciences at the Weiz- mann Institute of Science, where he spent most of his career and where he held the Estrin family chair. In recent years, Amir was a faculty member at New York University where he was a NYU Silver Professor. Throughout his career, in spite of an impressive list of achievements, Amir remained an extremely modest and selfless researcher. His unique combination of excellence and integrity has set the tone in the large community of researchers working on specification and verification of programs and systems, program semantics and automata theory. Amir was devoid of any arrogance and those who knew him as a young promising researcher were struck how he maintained his modesty throughout his career. Amir has been an active and extremely hard working researcher till the last moment. His sudden death left those who knew him in a state of shock and disbelief. For his achievements Amir received the 1996 ACM Turing Award. The citation reads: “For seminal work introducing temporal logic into computing science and for outstanding contributions to program and system verification.” Amir also received, for his contributions, the 2000 Israel Award in the area of exact sciences. More recently, in 2007, he shared the ACM Software System Award.

The Best Nurturers in Computer Science Research
The Best Nurturers in Computer Science Research Bharath Kumar M. Y. N. Srikant IISc-CSA-TR-2004-10 http://archive.csa.iisc.ernet.in/TR/2004/10/ Computer Science and Automation Indian Institute of Science, India October 2004 The Best Nurturers in Computer Science Research Bharath Kumar M.∗ Y. N. Srikant† Abstract The paper presents a heuristic for mining nurturers in temporally organized collaboration networks: people who facilitate the growth and success of the young ones. Specifically, this heuristic is applied to the computer science bibliographic data to find the best nurturers in computer science research. The measure of success is parameterized, and the paper demonstrates experiments and results with publication count and citations as success metrics. Rather than just the nurturer’s success, the heuristic captures the influence he has had in the indepen- dent success of the relatively young in the network. These results can hence be a useful resource to graduate students and post-doctoral can- didates. The heuristic is extended to accurately yield ranked nurturers inside a particular time period. Interestingly, there is a recognizable deviation between the rankings of the most successful researchers and the best nurturers, which although is obvious from a social perspective has not been statistically demonstrated. Keywords: Social Network Analysis, Bibliometrics, Temporal Data Mining. 1 Introduction Consider a student Arjun, who has finished his under-graduate degree in Computer Science, and is seeking a PhD degree followed by a successful career in Computer Science research. How does he choose his research advisor? He has the following options with him: 1. Look up the rankings of various universities [1], and apply to any “rea- sonably good” professor in any of the top universities.

ABSTRACT (Maxrmum 200 words) Abstract. It has been repeatedly observed that the standard safety-liveness classification of properties of reactive systems does not fit for real-time proper- ties. This is because the implicit “liveness” of time shifts the spectrum towards the safety side. While, for example, response - that “something good” will happen, eventually - is a classical liveness property, bounded response - that “something good” will happen soon, within a certain amount of time - has many characteristics of safety.

Noname manuscript No. (will be inserted by the editor) Turing Award elites revisited: patterns of productivity, collaboration, authorship and impact Yinyu Jin1 · Sha Yuan1∗ · Zhou Shao2, 4 · Wendy Hall3 · Jie Tang4 Received: date / Accepted: date Abstract The Turing Award is recognized as the most influential and presti- gious award in the field of computer science(CS). With the rise of the science of science (SciSci), a large amount of bibliographic data has been analyzed in an attempt to understand the hidden mechanism of scientific evolution. These include the analysis of the Nobel Prize, including physics, chemistry, medicine, etc. In this article, we extract and analyze the data of 72 Turing Award lau- reates from the complete bibliographic data, fill the gap in the lack of Turing Award analysis, and discover the development characteristics of computer sci- ence as an independent discipline. First, we show most Turing Award laureates have long-term and high-quality educational backgrounds, and more than 61% of them have a degree in mathematics, which indicates that mathematics has played a significant role in the development of computer science. Secondly, the data shows that not all scholars have high productivity and high h-index; that is, the number of publications and h-index is not the leading indicator for evaluating the Turing Award. Third, the average age of awardees has increased from 40 to around 70 in recent years. This may be because new breakthroughs take longer, and some new technologies need time to prove their influence. Besides, we have also found that in the past ten years, international collabo- ration has experienced explosive growth, showing a new paradigm in the form of collaboration.

COS 360 Programming Languages Formal Semantics
COS 360 Programming Languages Formal Semantics Semantics has to do with meaning, and typically the meaning of a complex whole is a function of the meaning of its parts. Just as in an English sentence, we parse a sentence into subject, verb, objects, adjectives(noun qualifiers) and adverbs(verb qualifiers), so with a program we break it up into control structures, statements, expressions, each of which has a meaning. The meanings of the constituents contribute to the meaning of the program as a whole. Another way this is put is to say that the semantics is compositional en.wikipedia.org/wiki/Denotational_semantics#Compositionality Consequently, the grammar of a language guides the exposition of its meaning. Each of the three approaches to formal semantics, axiomatic, operational, and denotational, will use the grammar as a structuring device to explain the meaning. The grammar used, however, is not the same one that the compiler’s parser uses. It eliminates the punctuation and just contains the relevant, meaning carrying pieces and is often ambiguous, but the notion is that the parsing has already taken place and the parse tree simplified to what is referred to as an abstract syntax tree. Learning Objectives 1. to understand the difference between the abstract syntax trees used in expositions of semantics and the concrete syntax trees, or parse trees, used in parsing 2. to understand how the abstract syntax tree contributes to the explanation of program- ming language semantics 3. to understand the three major approaches to programming language semantics: ax- iomatic, operational, and denotational 4. to understand how axiomatic semantics can be used to prove algorithms are correct 5.

Etude on Recursion Elimination by Program Manipulation and Problem Analysis
Etude on Recursion Elimination by Program Manipulation and Problem Analysis Nikolay V. Shilov Innopolis University Russia [email protected] Transformation-based program verification was a very important research topic in early years of theory of programming. Great computer scientists contributed to these studies: John McCarthy, Amir Pnueli, Donald Knuth ... Many fascinating examples were examined and resulted in recursion elimination techniques known as tail-recursion and as co-recursion. In the present paper we examine another (new we believe) example of recursion elimination via program manipulations and problem analysis. The recursion pattern of the study example matches neither tail-recursion nor co-recursion pattern. 1 Introduction 1.1 McCarthy 91 function Let us start with a short story [7] about the McCarthy 91 function M : N ! N, defined by John McCarthy1 as a test case for formal verification. The function is defined recursively as n − 10, if n > 100; M(n) = M(M(n + 11)), if n ≤ 100. The result of evaluating the function are given by n − 10, if n > 101; M(n) = (1) 91, if n ≤ 101. The function was introduced in papers published by Zohar Manna, Amir Pnueli and John McCarthy in 1970 [15, 16]. These papers represented early developments towards the application of formal methods to program verification. The function has a “complex” recursion pattern (contrasted with simple patterns, such as recurrence, tail-recursion or co-recursion). Nevertheless the McCarthy 91 function can be computed by an iterative algorithm/program. Really, let us consider an auxiliary recursive function Maux : N × N ! N 8 n m < , if = 0; Maux(n;m) = Maux(n − 10; m − 1), if n > 100 and m > 0; : Maux(n + 11; m + 1), if n < 100 and m > 0.
