Abstract Läuchli and Pincus showed that existence of algebraic completions of all fields cannot be proved from Zermelo‐Fraenkel set theory alone. On the other hand, important special cases do follow. In particular, I show that an algebraic completion of can be constructed in Zermelo‐Fraenkel set theory.

We present the results of a search for potential transit signals in the full 17-quarter data set collected during Kepler's primary mission that ended on May 11, 2013, due to the on-board failure of a second reaction wheel needed to maintain high precision, fixed, pointing. The search includes a total of 198,646 targets, of which 112,001 were observed in every quarter and 86,645 were observed in a subset of the 17 quarters. We find a total of 12,669 targets that contain at least one signal that meets our detection criteria: periodicity of the signal, a minimum of three transit events, an acceptable signal-to-noise ratio, and four consistency tests that suppress false positives. Each target containing at least one transit-like pulse sequence is searched repeatedly for other signals that meet the detection criteria, indicating a multiple planet system. This multiple planet search adds an additional 7,698 transit-like signatures for a total of 20,367. Comparison of this set of detected signals with a set of known and vetted transiting planet signatures in the Kepler field of view shows that the recovery rate of the search is 90.3%. We review ensemble properties of the detected signals and present various metrics useful in validating these potential planetary signals. We highlight previously undetected planetary candidates, including several small potential planets in the habitable zone of their host stars.

The intent of this panel is to stimulate discussion around the design of HCI for handhelds and related applications in pervasive communication scenarios. The panel will create a provocative framework for future interactive communications and will generate a debate with the audience around the emerging and contentious topic of using mobile devices as main interfaces in a ubiquitous communication experience. It is expected that the panelists will promote inter-disciplinary and multidisciplinary discussion about a range of HCI issues including: management of multiple user interactions, interaction between mobile phones and other devices, the development of usable design models for convergent media, special HCI considerations around media sharing, new applications and new forms of interactive content more suitable in pervasive communication contexts. Other ethical, legal, business and social implications of ubiquitous communications may also be raised. Short position statements will be followed by moderated debate between panelists that will be open to questions from the floor stimulating high interaction with the audience. The panel will conclude with a summarization of the most relevant outcomes of the discussion.KeywordsMobile PhoneUbiquitous SystemMobile HandsetMobile ContextExtreme SportThese keywords were added by machine and not by the authors.

<div class="htmlview paragraph">Propelled by the renewed international interest in returning to the Moon, an international consortium organized the first European Lunar Base Design Workshop in the summer of 2002. The objective of this Workshop was to propose new design concepts for human and robotic exploration of the Moon and move beyond the outdated ‘man-in-a-can’ genre of space architecture. The Workshop introduced a new genre in lunar base architecture, deriving from bold, innovative and unconventional thinking. It generated experimental concepts for sustainable, advanced, user-oriented architectures for future lunar bases. The Workshop participants chose diverse moon mission scenarios including ice mining, solar cell production, lunar telescopes, He3 mining, research and commercial operations.</div> <div class="htmlview paragraph">This paper will present the most important explorations and concepts from this Workshop. It will discuss the rationale behind adopting a multidisciplinary and multicultural design studio approach. It will present a summary of four of the seven designs generated at the Workshop and will then go on to discuss in detail the remaining three concepts as Case Studies. The objective of these Case Studies will be to showcase three completely different architectural paradigms: (<span class="xref">1</span>) a habitat buried under lunar regolith, (<span class="xref">2</span>) a stationary surface habitat, and (<span class="xref">3</span>) a mobile habitat.</div>
