In this paper, we present recent developments in the AltErgo SMT-solver to e ciently discharge proof obligations (POs) generated by Atelier B. This includes a new plugin architecture to facilitate experiments with di erent SAT engines, new heuristics to handle quantied formulas, and important modi cations in its internal data structures to boost performances of core decision procedures. Experim...

This paper presents camera mouse system with additional feature: "CTRL ALT DEL" key. The previous gaze-based camera mouse systems are only considering how to obtain gaze and making selection. We proposed gaze-based camera mouse with "CTRL ALT DEL" key. Infrared camera is put on top of display while user looking ahead. User gaze is estimated based on eye gaze and head pose. Blinking and mouth de...

AC-completion efficiently handles equality modulo associative and commutative function symbols. When the input is ground, the procedure terminates and provides a decision algorithm for the word problem. In this paper, we present a modular extension of ground AC-completion for deciding formulas in the combination of the theory of equality with user-defined AC symbols, uninterpreted symbols and a...

The treatment of the axiomatic theory of floating-point numbers is out of reach of current SMT solvers, especially when it comes to automatic reasoning on approximation errors. In this paper, we describe a dedicated procedure for such a theory, which provides an interface akin to the instantiation mechanism of an SMT solver. This procedure is based on the approach of the Gappa tool: it performs...

BACKGROUND Current guidelines introduce periodic monitoring of serum alanine transaminase (ALT) as the first-line modality in follow-up patients, with a hepatitis B virus (HBV) inactive carrier state. OBJECTIVES This study aimed to determine the incidence rate and patterns of ALT fluctuations and prognostic values for the development of chronic HBV e antigen (HBeAg)-negative hepatitis B (CHB)...

BACKGROUND The efficacy of serum alanine aminotransferase (ALT) levels in predicting the severity of hepatitis C virus (HCV) infection is unclear. OBJECTIVE To compare histologic scoring of liver pathology in patients with chronic HCV infection with normal or elevated serum ALT. METHODS Liver biopsies were performed in patients with HCV infection and either normal (n=40) or elevated (n=76) ...

A novel multiplex PCR method using three sets of specific primers was developed for the detection of the cytotoxic (act), heat-labile (alt), and heat-stable (ast) enterotoxin genes in Aeromonas spp. This assay was used to characterize 35 reference strains as well as 537 food-borne isolates. A total of seven gene pattern combinations were encountered, including act, alt, act/alt, act/alt/ast, ac...

It is quite easy to see that (2) and (3) give best possible results. Upper estimates for n were also given in [2] if either (Alt..., An)eS(k, </, m) and /<^(m+l) or if (Alt..., An)eS(k, I, m) and l^^(m+k), but the results in these cases are not best possible. Other results of this kind have been established in [3] and [4] which settle certain conjectures made in [2]. In this note we establish t...
