The batch execution modes of PVS are powerful, but highly technical, features of the system that are mostly accessible to expert users. This paper presents a PVS tool, called ProofLite, that extends the theorem prover interface with a batch proving utility and a proof scripting notation. ProofLite enables a semi-literate proving style where specification and proof scripts reside in the same fil...

The veri cation of functionality of the input output logic properties often composes the majority of software requirements analysis Automated theorem provers ATPs such as SRI s Prototype Veri cation System PVS have been successfully used in the formal veri cation of functional properties However such functional methods are not readily applicable to the veri cation of the real time software re q...

INTRODUCTION Coronary artery disease (CAD) is an important etiology of atrial fibrillation (AF). Coronary artery calcification is a marker of coronary atherosclerosis and coronary events. The purpose of this study was to investigate whether larger left atrium (LA) and pulmonary veins (PVs) were seen by multidetector computed tomography (MDCT) scans in those patients with higher coronary calcium...

OBJECTIVE Pulmonary vein (PV) anatomy has drawn attention since assumption that atrial fibrillation (AF) may originate from PVs and that electrical isolation of PVs may be beneficial in eliminating these triggers. The present study aims to investigate PV anatomy and its variations in a sample of Turkish patients undergoing PV isolation (PVI) for AF. METHODS 250 patients underwent multidetecto...

The intracellular protozoan Leishmania replicates in parasitophorous vacuoles (PV) that share many features with late endosomes/lysosomes. L. amazonensis PVs expand markedly during infections, but the impact of PV size on parasite intracellular survival is still unknown. Here we show that host cells infected with L. amazonensis upregulate transcription of LYST/Beige, which was previously shown ...

In this paper we discuss how we intend to develop a specialized theorem proving environment for the Hybrid I/O Automata (HIOA) framework [7] over the PVS [11] theorem prover, and some of the issues involved. In particular, we describe approaches to using PVS that allow and encourage the development of useful proof strategies, and note some desired PVS features that would further help us to do s...

Background Pulmonary vein stenosis (PVS) is a rare complication of atrial fibrillation (AF) ablation with a rate of significant stenosis, defined as >50%, of 1.3% in a recent multicenter study. As significant morbidity is associated with PVS, detection and surveillance with non-invasive imaging is routine. In this study, we hypothesized that prediction of PVS can be determined with early MRI to...

We examine the employment of word embeddings for machine translation (MT) of phrasal verbs (PVs), a linguistic phenomenon with challenging semantics. Using word embeddings, we augment the translation model with two features: one modelling distributional semantic properties of the source and target phrase and another modelling the degree of compositionality of PVs. We also obtain paraphrases to ...

Communication protocols pose interesting and diicult challenges for veriication technologies. The state spaces of interesting protocols are either innnite or too large for nite-state veriication techniques like model checking and state exploration. Theorem proving is also not eeective since the formal correctness proofs of these protocols can be long and complicated. We describe a series of pro...

INTRODUCTION The phosphodiesterase-III inhibitor milrinone improves ventricular contractility, relaxes pulmonary arteries and reduces right ventricular afterload. Thus, it is used to treat heart failure and pulmonary hypertension (PH). However, its action on pulmonary veins (PVs) is not defined, although particularly PH due to left heart disease primarily affects the pulmonary venous bed. We ex...
