  • In this paper we improve an earlier result by Bukhgeim and Uhlmann [1], by showing that in dimension n ≥ 3, the knowledge of the Cauchy data for the Schr¨dinger equation measured on possibly very small subsets of the o boundary determines uniquely the potential. We follow the general strategy of [1] but use a richer set of solutions to the Dirichlet problem. This implies a similar result for the problem of Electrical Impedance Tomography which consists in determining the conductivity of a body by making voltage and current measurements at the boundary. ...

  • We show that the Dirichlet to Neumann map for the equation ∇·σ∇u = 0 in a two-dimensional domain uniquely determines the bounded measurable conductivity σ. This gives a positive answer to a question of A. P. Calder´n o from 1980. Earlier the result has been shown only for conductivities that are sufficiently smooth. In higher dimensions the problem remains open. Contents Introduction and outline of the method

  • By early summer he was free enough to write. “I feel that now I can try to conjure something up for Princeton.” Disks and No Disks was the title of what evolved. Barr suggested one or more of the disks be painted orange to honor the colors of Old Nassau. A wary Calder replied, “After my initial reluctance to paint anything orange, I think all 3 disks might be good.” A few weeks later he amended this, “I suggest that you paint the smallest ‘Orange.’” In anticipation of the artist’s visit to Princeton in November 1971, all four solid disks had been painted orange.

  • The Parthenon sculptures associated with the classical Greek sculptor Pheidias were increasingly influential and the influx of classical art into Britain through the mid nineteenth century, such as the sculptures from Nereid Monument in Lycia and the Mausoleum of Halicarnassus in Bodrum, only served to emphasise the importance attributed to Greek art (Challis, From the Harpy Tomb).

  • Closer to home, PassivSystem’s Chief Executive Officer and founder Colin Calder got the idea for his company when he tried to build a zero-carbon footprint house in Tuscany and discovered that none of the green energy systems he wanted to use were compatible with each other. Calder immediately saw the incompatibility as a business opportunity. The experience led him to design a networked control system relying on internal and external sensors that synchronizes the different sources of energy entering a house in order to get the maximum efficiency at the lowest cost.

  • We present a notation for the declarative statement of morphological relationships and lexieal rules, based on the traditional notion of Word and Paradigm (cf Hockett 1954). The phenomenon of blocking arises from a generalized version of Kiparsky's (1973) Elsewhere Condition, stated in terms of ordering by subsumption over paradigms. Orthographic constraints on morphemic alternation are described by means of string equations (Siekmann 1975).

  • We present an algorithm for the generation of sentences from the semantic representations of Unification Categorial Grammar. We discuss a variant of Shieber's semantic monotonicity requirement and its utility in our algorithm. We indicate how the algorithm may be extended to other grammars obeying the same requirement. Appendices contain a full listing of the program and a trace of execution of the algorithm.

  • Giai đoạn những năm 1950 - 1960 là giai đoạn khởi đầu, khi công nghệ chưa được thương mại hoá. Điện lần đầu tiên được sản xuất bằng năng lượng hạt nhân vào ngày 20/12/1951 tại lò thử nghiệm EBR-1 của Mỹ và thắp sáng được bốn bóng đèn. Tổ máy Điện Hạt Nhân đầu tiên là lò graphit nước nhẹ 5 MW(e) tại Obninsk của Nga, bắt đầu hoạt động năm 1954 và ngừng hoạt động ngày 30/4/2002.

  • This issue of the journal reports some selected contributions from the workshops BioConcur 2004 chaired by Anna Ingolfsdottir and Hanne Riis Nielson and BioConcur 2005 chaired by Bud Mishra and Corrado Priami. There are three contributions from BioConcur 2004. The first one is by Calder, Gilmore and Hillston on the modelling of signalling pathways using the stochastic process algebra PEPA. The second contribution is by Kuttler and Niehren on gene regulation in π-calculus.

  • it follows as a theorem from a set of axioms and inference rules. Especially by the work of Van Benthem (1986) and Moortgat (1988) this view, which we will name with Moortgat (1987a) Lambek Theorem Proving (LTP; Lambek, 1958), has become popular among a number of linguists. The descriptive power of LTP can be extended if unification (Shieber, 1986) is added. Several theories have been developed that combine categorial formalisms and unification based formalisms. Within Unification Categorial Grammar (UCG, Calder et al., 1988, Zeevat et al.
