BACKGROUND AND PURPOSE The purpose of this study was to assess how well the anatomy of the jugular foramen (JF) could be displayed by 3T MR imaging by using a 3D contrast-enhanced fast imaging employing steady-state acquisition sequence (CE-FIESTA) and a 3D contrast-enhanced MR angiographic sequence (CE-MRA). MATERIALS AND METHODS Twenty-five patients free of skull base lesions were imaged on...

Logical analysis of data (LAD) is one of the methodologies for extracting knowledge as a Boolean function f from a given pair of data sets (T; F ) on attributes set S of size n, in which T (resp., F ) f0; 1g n denotes a set of positive (resp., negative) examples for the phenomenon under consideration. In this paper, we consider the case in which extracted knowledge has a decomposable structure;...

in this paper, the security of a distance bounding protocol is analyzed which has been recently proposed by jannati and falahati (so-called jf). we prove that an adversary can recover key bits of jf protocol with probability of “1” while the complexity of attack is “2n” runs of protocol. in addition, we propose an improved protocol and prove that the improved protocol is resistant to mafia frau...

Abstra t. In this paper, we onsider the hamiltonian properties of two-dimensional torus networks with the set F of faulty elements(verti es and/or edges). We will show that (1) if m 3, n 3, and n is odd, m n torus F is hamiltonianonne ted for any F with jF j 1, (2) if both m and n with m;n 4, are even, m n torus F is bihamiltonianonne ted for any F with jF j 1, and (3) if m 3, n 3, and n is odd...

1. Some basic facts Denote by O = ON+1 the ring of germs of holomorphic functions f = f(z0, · · · , zN ) defined in a neighborhood of ~0 ∈ CN+1. We denote by m ⊂ O the maximal ideal of O, f ∈ m ⇐⇒ f(~0) = 0. Let f ∈ m. Assume ~0 is an isolated critical point of f , i.e. ~0 is an isolated point of the variety ∂zif = 0, ∀i = 0, · · · , N. We define the Jacobian ideal of f to be the ideal Jf ⊂ O g...

BACKGROUND Surgical removal of jugular foramen (JF) neurinomas remains controversial because of their radicality in relation to periosteal sheath structures. OBJECTIVE To clarify the particular meningeal structures of the JF with the aim of helping to eliminate surgical complications of the lower cranial nerves (LCNs). METHODS We sectioned 6 JFs and examined histological sections using Mass...

Arsenic, a common environmental pollutant, is toxic to many mammalian cells. However, the arsenic-induced toxicity to aquatic animal species is unclear. This study attempted to compare the arsenic-induced cytotoxicity in various fish cells. Two fish cell lines, JF (fin cells of Therapon jarbua) and TO-2 cells (ovary cells of Tilapia), were treated with sodium arsenite in two ways to mimic acute...
