OBJECTIVES/HYPOTHESIS To examine how preoperative imaging characteristics correlate with sialendoscopic findings and operative outcomes in patients with obstructive parotid symptoms. STUDY DESIGN Retrospective review. METHODS We identified 112 consecutive patients who underwent 134 unilateral or bilateral parotid gland sialendoscopies between December 2005 and August 2013. We reviewed clini...

Let X and Y be completely regular spaces and E and F be Hausdorff topological vector spaces. We call a linear map T from a subspace of C(X, E) into C(Y, F ) a Banach-Stone map if it has the form Tf(y) = Sy(f(h(y)) for a family of linear operators Sy : E → F , y ∈ Y , and a function h : Y → X. In this paper, we consider maps having the property: (Z) ∩ki=1 Z(fi) 6= ∅ ⇐⇒ ∩ k i=1Z(Tfi) 6= ∅, where ...

A variety of factors influence the formation of calcium oxalate kidney stones, including gender, diet, and urinary excretion of calcium, oxalate, and uric acid. Several of these factors may be related to body size. Because men on average have a larger body size and a threefold higher lifetime risk of stone formation than women, body size may be an important risk factor for calcium oxalate stone...

One of the most serious principles in production theory in economic is the principle of "efficiency". Simply put, efficiency can be defined as the demand that the desired goals (outputs) are achieved with the minimum use of the available resources (inputs). In order to, distinguish the relative efficiency of organizational units with multiple inputs to produce multiple outputs, "Data Envelopmen...

For a smooth canonically embedded curve C of genus 9 together with pencil |L| degree 6, we study the relative canonical resolution C⊂X⊂P8, where X is scroll swept out by |L|. We show that second syzygy bundle in this C⊂X unbalanced. The proof reveals new geometric connection between universal Brill–Noether variety W9,61 and moduli space Fh lattice polarized K3 surfaces (for certain rank 3 h). A...

EQ-algebras were introduced by Nov?ak in [16] as an algebraic structure of truth values for fuzzy type theory (FTT). Nov?k and De Baets [18] various kinds such good, residuated, lattice ordered EQ-algebras. In any logical structures, using filters, one can construct other structures. With this inspirations, means fantastic filters we MV-algebras. Also, study prelinear introduce a new kind filte...

hairball in a urethral diverticulum has rarely been reported. these hairballs are usually formed in the diverticulum coated with a hair bearing epithelium and can lead to urinary obstruction or infection. using laser is a safe way to ablate such stones.

Gabriel Taubin Brown University Holly Rushmeier, who’s served as associate editor in chief (AEIC) for special issues since 2007, has recently been appointed co-editor in chief of Eurographics’ Computer Graphics Forum, effective May 2010. Owing to her increased responsibilities and numerous other commitments, Holly has decided she’ll be unable to continue serving effectively in her current CG&A ...

In the theory of lattice-ordered groups, there are interesting examples of properties — such as projectability — that are defined in terms of the overall structure of the lattice-ordered group, but are entirely determined by the underlying lattice structure. In this paper, we explore the extent to which projectability is a lattice-theoretic property for more general classes of algebras of logic...
