Quantum Neural Network for Quantum Neural Computing.

Neural networks have achieved impressive breakthroughs in both industry and academia. How to effectively develop neural networks on quantum computing devices is a challenging open problem. Here, we propose a new quantum neural network model for quantum neural computing using (classically controlled) single-qubit operations and measurements on real-world quantum systems with naturally occurring environment-induced decoherence, which greatly reduces the difficulties of physical implementations.

[Influence of autoclave sterilization on dimensional stability and detail reproduction of 5 additional silicone impression materials].

Objective: To evaluate the dimensional stability and detail reproduction of five additional silicone impression materials after autoclave sterilization.

Methods: Impressions were made on the ISO 4823 standard mold containing several marking lines, in five kinds of additional silicone. All the impressions were sterilized by high temperature and pressure (135 °C, 212.

[In vivo model to evaluate the accuracy of complete-tooth spectrophotometer for dental clinics].

Objective: To test ΔE between measured value and right value from the Crystaleye complete-tooth spectrophotometer, and to evaluate the accuracy rate of the spectrophotometer.

Methods: Twenty prosthodontists participated in the study. Each of them used Vita 3D-Master shadeguide to do the shade matching, and used Crystaleye complete-tooth spectrophotometer (before and after the test training) tested the middle of eight fixed tabs from shadeguide in the dark box.

[Application and comparison of two shade guide training systems].

Objectives: To evaluate the effect of shade guide training box and shade guide training software on shade matching ability of observers when used separately. To find out the difference between two training plans when the two training methods were used in combination, and to provide information on shade matching training system.

Methods: Sixty-two postgraduate dental students who specialized in prosthodontics with 1 to 5 year clinical experience were enrolled in this study.

[Comparison of shade matching accuracy of tabs of shadeguide and tabs out of shadeguide].

Objective: To compare the shade matching accuracy between tabs of shade guide and tabs out of shade guide by prosthodontists.

Methods: Sixty-two graduate students who had 1 to 5 years clinical experience without color blindness were included in this study. Twenty-nine tabs from Vita 3D-Master shadeguide and 7 tabs out of Vita 3D-Master shade guide but from Vita Bleachedguide 3D-Master were taken as the targets of shade matching and observed under the standard light.

[The influence of toothguide training box on shade matching veracity].

Purpose: The aim of the study was to evaluate the influence of toothguide training box(TTB) on shade matching veracity, and compare the differences of influence on shade matching veracity of tabs of shadeguide and on that of tabs out of shadeguide.

Methods: 31 graduated students who had 1 to 5-year clinical experience without color blindness were trained by TTB once a week for 3 weeks. Elapsed time and scores from the training system were recorded each time.
