This study develops and tests an MR thermometry method combined with SMASH navigators in phantom experiments mimicking human liver motion with the purpose of detecting and correcting motion artifacts in thermal MR images. Experimental data were acquired on a 3T MRI scanner. Motion artifacts of mobile phantoms mimicking human liver motion were detected and corrected using the SMASH navigators an...

Let K be an algebraically closed field. Building upon previous work, we classify, up to isomorphism of algebras, quadratic graded twisted tensor products K[x,y] and K[z]. When such algebra is Artin-Schelter regular, identify its point scheme type, in the sense [6]. We also describe which three-dimensional Sklyanin algebras contain a subalgebra isomorphic quantum P1, show that every this family ...

Let V be a simple vertex operator algebra and G a finite automorphism group of V . It was shown in [DY] that any irreducible V -module is a completely reducible V G-module. In this paper, we show that any g-twisted V -module is also a completely reducible V G-module if V is g-rational. For each g ∈ G, a g-twisted Zhu algebra Ag,n(V ) plays an important role, but the given product in Ag,n(V ) de...

Recently there appeared an interesting paper by Fischman and Montgomery[FM] in which some abstract constructions due to the author for Hopf algebras in braided categories [M6][M7][M8][M9] were applied to obtain a Schur’s double centraliser theorem for color Lie algebras. Unfortunately, in the introduction and preliminaries of their paper, some incorrect statements are made which could cause con...

background and aims. the manufacturing process of rotary ni-ti file can influence its resistance to fracture. the rotary profile (dentsply-maillefer, baillagues, switzerland) is manufactured by grinding mechanism whereas twisted file (sybron endo, usa) is manufactured with a twisting method. the purpose of this study was to comparatively evaluate the effect of manufacturing process on distortio...

African Americans and Hispanics have disproportionate rates of uncontrolled essential hypertension (EH) compared to Non-Hispanic Whites. Medication non-adherence (MNA) is the leading modifiable behavior to improved blood pressure (BP) control. The Smartphone Medication Adherence Stops Hypertension (SMASH) program was developed using a patient-centered, theory-guided, iterative design process. E...
