Entanglement reciprocation between atomic qubits and entangled coherent state

Introducing classical fields, we can transfer entanglement completely from discrete qubits into entangled coherent state. The entanglement also can be retrieved from the continuous-variable state of the cavities to the atomic qubits. Via postselection measure, atomic entangled state and entangled coherent state can be mutual transformed fully.Comment: 5 pages, 3 fighres. accepted by J Phys

IB-UQ: Information bottleneck based uncertainty quantification for neural function regression and neural operator learning

We propose a novel framework for uncertainty quantification via information bottleneck (IB-UQ) for scientific machine learning tasks, including deep neural network (DNN) regression and neural operator learning (DeepONet). Specifically, we incorporate the bottleneck by a confidence-aware encoder, which encodes inputs into latent representations according to the confidence of the input data belonging to the region where training data is located, and utilize a Gaussian decoder to predict means and variances of outputs conditional on representation variables. Furthermore, we propose a data augmentation based information bottleneck objective which can enhance the quantification quality of the extrapolation uncertainty, and the encoder and decoder can be both trained by minimizing a tractable variational bound of the objective. In comparison to uncertainty quantification (UQ) methods for scientific learning tasks that rely on Bayesian neural networks with Hamiltonian Monte Carlo posterior estimators, the model we propose is computationally efficient, particularly when dealing with large-scale data sets. The effectiveness of the IB-UQ model has been demonstrated through several representative examples, such as regression for discontinuous functions, real-world data set regression, learning nonlinear operators for partial differential equations, and a large-scale climate model. The experimental results indicate that the IB-UQ model can handle noisy data, generate robust predictions, and provide confident uncertainty evaluation for out-of-distribution data.Comment: 27 pages, 22figure

The Research on Establishment of “Clinical Practice Guide of Blood Specimen Collection, Preservation and Delivery for Clinical Nurse”: Protocol Description

INTRODUCTION AND OBJECTIVE: The correctness of the blood test is closely related to the sample. According to the recent reported data, 80 percentage unsatisfactory results of the clinical test are due to the poor quality of sample, especially the blood sample. Clinical practice guide (CPG) is directly to instruct the clinical nursing practice. And the recommendations in the clinical practice guide are based on the best available study evidences. There is lack of CPG about blood sample specimen collection, preservation and delivery (BSCPD) in China. Additionally, related published clinical studies are accumulated in a great deal. Therefore, establishing a CPG is necessarily and practicable. The detailed objectives are: 1) to describe and analyze the research status of BSCPD in China; 2) to describe and analyze the practice status of BSCPD in China; 3) to systematic appraise the available evidences of BSCPD; 4) to establish the clinical practice guide of BSCPD; 5) to judge the clinical practice guide of BSCPD. METHODS: Objective 1): Bibliometric analysis is applied, the database include China National Knowledge Infrastructure Database (CNKI) and Sino-med and the research period is from the year of 2003 to 2013; Objective 2): Questionnaire survey for all the registered clinical nurses in a grade three hospital; objective 3): Systematic review according to Cochrane collaboration handbook 5.1.0 is applied which includes assessment of risk of bias, data extraction, data analysis; Objective 4) and 5): Using the appraising guidelines research and evaluation (AGREE) to evaluate of the draft of CPG of BSCPD. RESULTS: Bibliometric analysis started in 2013, and search strategies have been established. Questionnaire survey setting and depth interviewees have been identified and communicated. CONCLUSIONS: The CPG of BSCPD will serve as an important resource in instructing and modifying clinical nursing practice. Given this CPG of BSCPD will be a draft version, the applicability and suitability of it will need a further evaluated in the real clinical nursing world
