The convex PBW-type Lyndon basis for two-parameter quantum group Ur,s (F4)is given. Assume that rs−1 is a primitive ℓ-th root of unity with ℓ odd, then the restricted $${\mathfrak{u}_{r,s}}({F_4})$$ as quotient Ur,s(F4) pointed, and Drinfel’d double structure under certain condition. All Hopf isomorphisms are determined, necessary sufficient condition to be ribbon algebra singled out by describ...
PURPOSE The purpose of this study is to mix dental ceramic powder in varying ratios and evaluate the effect of the mixing ratio on color and translucency. MATERIALS AND METHODS The ceramic powder of shade A3 of the same product was mixed with the shade A2 of three products: IPS e.max Ceram (Ivoclar Vivadent, Schaan, Liechtenstein), Vintage Halo (SHOFU Inc., Kyoto, Japan), and Ceramco 3 (Ceram...
Garbling schemes allow to construct two-party function evaluation with security against cheating parties (SFE). To achieve this goal, one party (the Garbler) sends multiple encodings of a circuit (called Garbled Circuits) to the other party (the Evaluator) and opens a subset of these encodings, showing that they were generated honestly. For the remaining garbled circuits, the garbler sends enco...
We evaluated the level of intraocular light scatter in a group of patients with retinitis pigmentosa (RP) who had minimal or no lens opacities, since such patients not infrequently complain of photoaversion. Intraocular light scatter was measured in 20 patients with RP who were < 60 years of age and who had no more than a trace of posterior subcapsular (PSC) lens opacity by slit-lamp evaluation...
OBJECTIVE Since the color of esthetic brackets should match that of teeth, the aims of this study were to determine the color and translucency of esthetic brackets by means of the clinically relevant use of a spectroradiometer, and to compare the color of brackets with that of a commercial shade guide. METHODS The color of central and tie-wing regions of four plastic and four ceramic brackets...
Objectives. To assess visually color-matching and blending-effect (BE) of a universal shade bulk-fill-resin-composite placed in resin-composite-models with different shades and cavity sizes and in natural teeth (extracted and patients' teeth). Materials and Methods. Resin-composite-discs (10 mm × 1 mm) were prepared of universal shade composite and resin-composite of shades: A1, A2, A3, A3.5, a...
We construct a protocol for constant round Two-Party Secure Function Evaluation in the standard model which improves previous protocols in several ways. We are able to reduce the number of calls to Oblivious Transfer by a factor proportional to the security parameter. In addition to being more efficient than previous instantiations, our protocol only requires black box calls to OT and Commitmen...
one very decisive factor in students’ academic destiny is the result they get at final term examinations. because of its importance, both students and teachers are curiously anxious about them. as normally it is the case, these final term tests are prepared hurriedly in short time by teachers which result in students’ dissatisfaction, complaining on how the test was different from their expecta...
in this study reference as one of the five cohesive devices in the achievement of textuality in english and persian narrative/descripitive written texts is focused on and analysed . to do so , the theoretical framework elaborated by halliday and hasan (1976) and its version adapted by the writer to match the sub-types of reference in farsi are applied to the analysis of reference in english and...
the purpose of the research is to examine if integrating cooperative learning into vocabulary learning helps to increase word recognition of students in an elementary school in iran. it tries to investigate whether cooperative learning approach enables students to improve their language learning. this research used stad (students team achievement division) as a cooperative model in this study. ...
