Du chien d’Ulysse, Argos, on connaît la fidélité et la mort qui marque le retour de son maître. L’ouvrage jeunesse Argos, le compagnon d’Ulysse, fait de ce personnage secondaire mais attachant un héros à hauteur d’enfant.

Cut-elimination, substitution and normalisation
No full textDate of Acceptance: 01/2015We present a proof (of the main parts of which there is a formal version, checked with the Isabelle proof assistant) that, for a G3-style calculus covering all of intuitionistic zero-order logic, with an associated term calculus, and with a particular strongly normalising and confluent system of cut-reduction rules, every reduction step has, as its natural deduction translation, a sequence of zero or more reduction steps (detour reductions, permutation reductions or simplifications). This complements and (we believe) clarifies earlier work by (e.g.) Zucker and Pottinger on a question raised in 1971 by Kreisel.Peer reviewe
I remember teaching English at Seabrook
No full textIn this "I remember" memoir, Isabell Waugh, a former teacher at Seabrook, compares and constrasts the different groups of students she taught. She remembers that native-born American teenagers tended to be more concerned with athletics and social activities, than academic matters. In comparison, Estonian and Japanese parents did not tolerate low academic performance, so students from the two groups often competed intensely with each other for academic achievement and recognition. Isabelle recalls that the Estonians were, in general, more sophisticated and better educated. Most of the children knew 3-5 languages, and were more advanced in math and science. She sensed that some Estonian parents felt that their homes at Seabrook were temporary, and that they would be returning to Estonia at some point. The Seabrook Educational and Cultural Center has been soliciting current and past residents of Seabrook Farms for an "I remember" project. Residents are asked to create narratives regarding their experiences at Seabrook Farms. These memories help preserve the history and multi-cultural heritage of Seabrook Farms
GlAIcomics: a deep neural network classifier for spectroscopy-augmented mass spectrometric glycans data
No full textCarbohydrate sequencing is a formidable task identified as a strategic goal in modern biochemistry. It relies on identifying a large number of isomers and their connectivity with high accuracy. Recently, gas phase vibrational laser spectroscopy combined with mass spectrometry tools have been proposed as a very promising sequencing approach. However, its use as a generic analytical tool relies on the development of recognition techniques that can analyse complex vibrational fingerprints for a large number of monomers. In this study, we used a Bayesian deep neural network model to automatically identify and classify vibrational fingerprints of several monosaccharides. We report high performances of the obtained trained algorithm (GlAIcomics), that can be used to discriminate contamination and identify a molecule with a high degree of confidence. It opens the possibility to use artificial intelligence in combination with spectroscopy-augmented mass spectrometry for carbohydrates sequencing and glycomics applications.</p
Isabelle Bell to Susan Niemcewicz, December 23, 1800
No full textIsabelle Bell wrote to Susan U. Niemcewicz in Elizabethtown, New Jersey. Bell expressed her disappointment in not receiving a line from Susan. She sent Bell Lucretia Rephans subscription epistle, but Susan refrained from writing a letter to her. Bell did not execute any of Susan’s commissions in New York because her time there was short. Miss Resham heard that Mr. B Livingston told his sister, Mrs. J. Livingston that he would offer Bell a salary to live in his house and take charge of his children’s education. Asked if Susan what she thought of her being an author and if Susan would subscribe to a small volume that may have the good fortune to rival the poems of the immortal Scarron.https://digitalcommons.kean.edu/lhc_1800s/1143/thumbnail.jp
Isabelle Stengers, Une autre science est possible ! Manifeste pour un ralentissement des sciences
No full textAlors que l’AERES est en passe de disparaître, le dernier livre de la philosophe belge des sciences Isabelle Stengers (Université Libre de Bruxelles), Une autre science est possible ! Manifeste pour un ralentissement des sciences, pourrait apparaître comme le compagnon idéal des gouvernants chargés de penser la refonte de l’évaluation de la recherche en France. Le propos est cependant bien plus vaste que ne le laisse à penser le sous-titre ou la quatrième de couverture, le livre nouant un ens..

Formalization of Isabelle Meta Logic in NuPRL
No full textNuPRL and Isabelle are two general purpose theorem provers. Both of them are based on a version of Constructive Higher Order Type Theory. In an earlier work the author has proposed an informal semantics of Isabelle Meta Logic in an extension of NuPRL Type Theory. An automated converter, based on this semantics, has been developed, that translates Isabelle theorem statements into NuPRL. This work presents a formalization of the above semantics in NuPRL. It starts with a deep embedding of Isabelle type and term syntax into NuPRL Constructive Type Theory. Next, two internal NuPRL functions are defined. One of them maps Isabelle types into NuPRL types and the other maps Isabelle terms into elements of appropriate NuPRL types. These two functions provide an interpretation of Isabelle in NuPRL. Finally, interpretations of all Isabelle Meta Logic rules are proven as theorems in some classical extension of NuPRL Type Theory. This formalization is aimed to provide a more secure foundation for the interaction between two systems
Security modeling and correctness proof using Specware and Isabelle
No full textSecurity modeling is the foundation to formal verification which is a core requirement for high assurance systems. This thesis explores how security models can be built in a simple and expressive manner using the Metaslang specification language in Specware. The models are subsequently translated, via the Specware to Isabelle Interface, to be proven for correctness in Isabelle which is a generic, interactive theorem proving environment. It is found that the translation between Specware and Isabelle is almost seamless and there is much potential in the use of Isabelle/HOL to discharge proof obligations that arise in developing Specware specifications, although the actual proving requires substantial knowledge and experience in logical calculus.Approved for public release; distribution is unlimited.Outstanding ThesisSingapore ST Electronics Ltd. author (civilian).http://archive.org/details/securitymodeling10945383
VIBRATIONAL SPECTROSCOPY OF GAS-PHASE PEPTIDES: A MODEL FOR UNDERSTANDING THE SECONDARY STRUCTURE OF PROTEINS
No full textAuthor Institution: FOM Institute for Plasma Physics "Rijnhuizen", Nieuwegein, The Netherlands; Fritz-Haber-Institut der Max-Planck-Gesellschaft, Berlin, GermanyExperiments on biomolecules in the gas phase, where the interaction with the environment is eliminated or controlled, provide fundamental insight into their structure and function. Understanding the formation of the secondary structure in peptides is a key point in the protein-folding problem. The aim of this project is to identify the intrinsic factors responsible for conformational stability, as well as the influence of a controlled environment. Particularly, the combination of IR and UV hole burning spectroscopy with molecular beam techniques has recently yielded detailed information on the structure of low energy conformations of a variety of biomolecules, among which several small peptides. In this contribution, the mid- and far-IR radiation produced by the Free Electron Laser for Infrared eXperiments (FELIX) is applied to address the local organization of peptides, i.e. the "secondary structure". We introduced a UV chromophore (benzyloxycarbonyl, referred to as Z) protecting function in the peptide, which allows us to extend the application of IR/UV hole burning spectroscopy to any peptide, instead of only those containing an aromatic amino-acid (Trp, Phe, Tyr). We investigate the mid-IR signature of two capped model peptides in the wavelength range beyond the well-known Amide bands (1500-1800 cm), which are commonly used as a diagnostic of the intramolecular H-bonding network. The 1000-1500 cm range offers a wealth of information leading to a precise assignment of the peptide's backbone conformation. The far IR region (<1000 cm) contains a number of bands that are poorly predicted by DFT calculations, which may be due to the presence of strongly anharmonic vibrations. Hence, the IR signature of the Amide bands and the mid-IR fingerprint of the backbone bands are quite complementary and offer a very detailed description of the secondary structure of peptides. \\[3mm] \small{1.
