Nobel Laureate Anthony J Leggett: A scientometric portrait
This paper attempts to analyse the publication productivity of Anthony J. Leggett, the 2003 Nobel Prize winner in physics. His contributions peaked in 1987, 1994, and 1998 with 10 papers each. He had 194 publications during 1964 - 2004 in domains like Superfluid 3He (65), Foundations of Quantum Mechanics (36), Dissipative Quantum Systems (24), Atomic Alkali Gases (18), and Miscellaneous (51)which were analysed for authorship pattern with his 70 collaborators. Most active collaborators with Anthony J Leggett were: A. Garg with six papers and A. O. MCaldeira, D. M. Ginsberg, D. J. Vanharlingen , F. Sols, S.Takagi and D. A. Wollman with five papers each. His productivity coefficient was 0.60 which clearly indicates that his productivity
increased after 50 percentile age. The highest degree of collaboration (1) for Anthony J. Leggett was found during 1964, 1971 and 1983. Journals have been the most preferred channel of communication, where as many as 139 papers out of 194 have been published. The core journals publishing his papers were: Phys. Rev. Leu. (42), Phys. Rev. B (9), J. Low Temp. Phys. (8),Phys. Rev. A (7), Ann. Phys. (6), Foundations of physics (6), J. Phys.(5), Prog. Theor: Phys. (5), and Rev. Mod. Phys. (5).Publication density was 3.02 and publication concentration was 3.59

Letters exchanged in June and July 1970 between Lorenzo A. Richards and Anthony E. Sowers
Three letters exchanged in June and July 1970 between Lorenzo A. Richards and Anthony E. Sowers: (1) Letter dated 23 July 1970 from Lorenzo A. Richards to Anthony E. Sowers, General Manager at Techsonics in Taos, New Mexico, responding to his letters of 24 June and 20 July regarding his soil water sensor; (2) Letter dated 20 July 1970 from Anthony E. Sowers to Lorenzo A. Richards, with an added question regarding techniques of measuring soil moisture; (3) Letter dated 24 June 1970 from Anthony E. Sowers to Lorenzo A. Richards inquiring about his system of measuring soil moistureJuly 23, 1970 Mr. Anthony E. Sowers General Manager, Techsonics Taos, New Mexico 87571 Dear Mr. Sowers: Your letters of 24 June and 20 July were received. I am now retired from the Salinity Laboratory and my home address is 4455 Fifth Street, Riverside, California 92501. Dr. Haise is correct in that I do have a new type soil water sensor that is in a late stage of development for commercial use. It makes use of the electrical conductivity of the soil solution, as does also the gypsum block, which latter I regard as of questionable value. I should be glad to talk with you about this new development, which will be used first for automatic irrigation control, if we should ever find ourselves within convenient proximity. I may be at the Tucson Meeting of the American Society of Agronomy. I gave soil water sensors based on thermal conductivity a "whirl", but gave up. There may be a manuscript from the Salinity Laboratory [C. J. Phene, G. J. Hoffman, S. L. Rawlins, authors] dealing with the electrothermal method and you may be interested in this manuscript when it becomes available. An article by D. D. Evans and colleague in Ho. 3, 1970, Soil Science Society of America Proceedings deals with thermal conductivity of soil and it may interest you. This work was done at the University of Arizona at Tucson. Sincerely, L. A. Richards Physicist (retired) LAR:als cc: S. L. Rawlins Dictated but not read before mailing.

Box 672 Riverside, California Dear Dr. Richards: Since writing my letter of June 24, 1970, I have come across a reference to work done by Shaw, Byron, and Baver in 1939 involving the determination of moisture ^y^soils by relative conductivity. Has any further work been done in this regard? Do you know where I can obtain a summary of the work that has been done in this area? I believe the reason for my interest is obvious-it is quite easy, with modern technology, to measure the rate of heat extraction from a probe. I will look forward to receiving your response to this letter and to my letter of June 24, 1970. Sincerely, Anth(m^>S£ Sowers Rio Pueblo Enterprises \ P, Q.

Box 672 Riverside, California Dear Dr. Richards: In a telephone conversation with Dr. Howard Haise on June 23, 1970, he indicated that considerable progress had been made in the past ten years or so in the matter of measuring the moisture content of soils. Techsonics is an electronic manufacturing firm located here in Taos, New Mexico. We are also involved in another firm known as Rio Pueble Enterprises which our main effort will be the development of a Christmas tree industry in Northern New Mexico. In connection with this, it seems desirable for us to be able to measure the moisture content of a field or of a container in a simple and fairly reliable manner* Dr. Haise indicated that he thought you had developed a new system involving a bridge technique so that moisture content readings could be taken in the field as needed without the necessity for planting cells in advance* I would be interested in any information which you might have available on this technique and any other relatively straight forward and convenient technique which you or someone else nay have developed. We are interested in this both from the point of view of our need for such a device in the tree growing business and from the point of view it possibly being an item which could be manufactured by Techsonics. I I will appreciate any information which you can offer and any guidance to further sources. Thank you for your trouble. Sincere Anthony j^y Genera^Taa^ Techs oMtfs Sowers fcger AES/l a

Including design in e-manufacturing
This paper reviews major issues in the implementation of e-manufacturing, particularly the design aspects. It will examine recent progress, drawing out particular issues that are being addressed. Use will be made of the work by the author and colleagues to devise rule-based design and Internet-based control of machines to illustrate how these developments affect the integrated e-manufacturing environment. A dynamic Simulink model of the way e-manufacture is affected by overall design delays is used to evaluate general solutions for partial and complete e-based companies. These models show how changing to improved designs reduces WI
Valid generalisation from approximate interpolation
Let H and C be sets of functions from domain X to R. We say that H validly generalises C from approximate interpolation if and only if for each j ? 0 and ffl; ffi 2 (0; 1) there is m 0 (j; ffl; ffi) such that for any function t 2 C and any probability distribution P on X , if m m 0 then with P m -probability at least 1 \Gamma ffi, a sample x = (x 1 ; x 2 ; : : : ; xm ) 2 X m satisfies 8h 2 H; jh(x i ) \Gamma t(x i )j ! j; (1 i m) =) P(fx : jh(x) \Gamma t(x)j jg) ! ffl: We find conditions that are necessary and sufficient for H to validly generalise C from approximate interpolation, and we obtain bounds on the sample length m 0 (j; ffl; ffi) in terms of various parameters describing the expressive power of H. 1 Introduction and Definitions Much work has recently been carried out on probabilistic models of machine learning such as the `probably approximately correct' (or pac) model due to Valiant [26]. In particular, the pac learning of f0; 1g-valued functions (equivalent..
