This paper describes NUSMV, a new symbolic model checker developed as a joint project between Carnegie Mellon University (CMU) and Istituto per la Ricerca Scientifica e Tecnolgica (IRST). NUSMV is designed to be a well structured, open, flexible and documented platform for model checking. In order to make NUSMV applicable in technology transfer projects, it was designed to be very robust, close...

We consider the reconstruction of sparse signals in the multiple measurement vector (MMV) model, in which the signal, represented as a matrix, consists of a set of jointly sparse vectors. MMV is an extension of the single measurement vector (SMV) model employed in standard compressive sensing (CS). Recent theoretical studies focus on the convex relaxation of the MMV problem based on the (2, 1)-...

In patients with pancreatic head cancer, tumor invasion of the portal vein (PV) or superior mesenteric vein (SMV) is common because of the close anatomical relationship of the pancreatic head and uncinate process to the venous portal system. Pancreatoduodenectomy (PD) with portal vein or superior mesenteric vein resection is well accepted for pancreatic head cancer because of the improvement in...

We evaluated the transition of dominant resistance-associated substitutions (RASs) in hepatitis C virus during long-term follow-up after the failure of DAAs (direct acting antivirals)-based therapy. RASs in non-structure (NS)3/4A, NS5A, NS5B, and deletions in NS5A from 20 patients who failed simeprevir/pegylated-interferon/ribavirin (SMV/PEG-IFN/RBV) and 25 patients who failed daclatasvir/asuna...

In this paper we address the problem of off-grid direction of arrival (DOA) estimation based on sparse representations in the situation of multiple measurement vectors (MMV). A novel sparse DOA estimation method which changes MMV problem to SMV is proposed. This method uses sparse representations based on weighted eigenvectors (SRBWEV) to deal with the MMV problem. MMV problem can be changed to...

Our system allows the formal verification of digital circuits using specifications expressed in English. Verification is carried out by the SMV model checker program [McM92]. SMV requires specifications to be written in the temporal logic CTL (computation tree logic). SMV’s model checking algorithm carries out inference over CTL formulas, with respect to a formal representation of a circuit. Th...

Sparse representation of a single measurement vector (SMV) has been explored in variety compressive sensing applications. Recently, SMV models have extended to solve multiple vectors (MMV) problems, where the underlying signal is assumed joint sparse structures. To circumvent NP-hardness \begin{document}$ \ell_0 $\end{document}</tex...

AIM To investigate wall shear stress (WSS) magnitude and distribution in cirrhotic patients with portal hypertension using computational fluid dynamics. METHODS Idealized portal vein (PV) system models were reconstructed with different angles of the PV-splenic vein (SV) and superior mesenteric vein (SMV)-SV. Patient-specific models were created according to enhanced computed tomography images...

OBJECTIVE We aimed to evaluate the relationships between the splenic index, right and left hepatic lobe volumes, diameters of splenic vein (SV), superior mesenteric vein (SMV) and the portal vein (PV) by Multidetector Computerized Tomography (MDCT). We also investigated indirect signs of portal venous flow pattern using these parameters. MATERIAL AND METHODS Following their contrast thoracoab...
