Herbelin presented (at CSL'94) a simple sequent calculus for minimal implicational logic, extensible to full rst-order intuitionistic logic, with a complete system of cut-reduction rules which is both con uent and strongly normalising. Some of the cut rules may be regarded as rules to construct explicit substitutions. He observed that the addition of a cut permutation rule, for propagation of s...

The use of the autologistic model for binary spatial data on a regular lattice is hindered by the necessity to evaluate the normalising constant which is intractable in all but small systems. An alternative Bayesian approach is presented using a hierarchical model where the observed data is the sign of a hidden conditional autoregressive Gaussian process. This has the advantage that the nor-mal...

Infinite lambda calculi extend finite lambda calculus with infinite terms and transfinite reduction. In this paper we extend some classical results of finite lambda calculus to infinite terms. The first result we extend to infinite terms is Böhm Theorem which states the separability of two finite βη-normal forms. The second result we extend to infinite terms is the equivalence of the prefix rel...

Irritable bowel syndrome (IBS) is one of the most common chronic gastrointestinal disorders, yet its pathophysiology is incompletely understood and pharmacological treatments remain unsatisfactory. Current therapeutic choices include a range of drugs aimed at normalising bowel habits, reducing pain or treating comorbid psychological symptoms. However, this individual symptom-targeted approach r...

Building on previous work by Coquand and Spiwack [8] we construct a strict domaintheoretic model for the untyped λ-calculus with pattern matching and term rewriting which has the property that a term is strongly normalising if its value is not ⊥. There are no disjointness or confluence conditions imposed on the rewrite rules, and under a mild but necessary condition completeness of the method i...

We present a version of system Fω in which the layer of type constructors is essentially the same as in the traditional presentation of Fω [Gir72], whereas provability of types is classical. The proof-term calculus accounting for the classical reasoning is a variant of Barbanera and Berardi’s symmetric λ-calculus [BB96]. We prove that the whole calculus is strongly normalising. For the layer of...

This paper examines the relationship between time to processing and RNA quality in placentas collected from women in a field setting in rural Gambia. Placental samples were collected from the villages and transferred to the laboratory. RNA was extracted using Trizol and integrity assessed using the RNA integrity number (RIN). Values were inversely correlated with delay in processing. Expression...

Twitter provides access to large volumes of data in real time, but is notoriously noisy, hampering its utility for NLP. In this paper, we target out-of-vocabulary words in short text messages and propose a method for identifying and normalising ill-formed words. Our method uses a classifier to detect ill-formed words, and generates correction candidates based on morphophonemic similarity. Both ...

For a large Markovian model, a “product form” is an explicit description of the steady-state behaviour which is otherwise generally untractable. Being first introduced in queueing networks, it has been adapted to Markovian Petri nets. Here we address three relevant issues for product-form Petri nets which were left fully or partially open: (1) we provide a sound and complete set of rules for th...

BACKGROUND Patients with prosthetic heart valves are a challenge to any anesthesiologist due to the risk of infective endocarditis, bleeding and thrombosis. CASE PRESENTATION We present anesthetic management of a 58-year-old Indian lady with a prosthetic (mechanical) heart valve who underwent hemireplacement arthroplasty. CONCLUSION Patients with prosthetic heart valves, especially those wi...
