From obligation to action: unraveling the roles of social responsibility and prosocial tendency in shaping Chinese doctors' vaccine hesitancy.

Background: The hesitation of healthcare professionals towards vaccines is becoming increasingly concerning, potentially undermining public confidence in vaccination programs. This study aimed to investigate the relationship between social responsibility, Prosocial tendency, and vaccine hesitancy among Chinese doctors, and to identify demographic factors associated with vaccine hesitancy.

Method: A cross-sectional survey was conducted among 976 Chinese doctors.

Optimal control of quantum state preparation and entanglement creation in two-qubit quantum system with bounded amplitude.

We consider the optimal control problem in a two-qubit system with bounded amplitude. Two cases are studied: quantum state preparation and entanglement creation. Cost functions, fidelity and concurrence, are optimized over bang-off controls for various values of the total duration, respectively.

[Seroepidemiology of varicella among the healthy population aged 1-19 years in Harbin, China].

Objective: To investigate the level of IgG antibody to varicella in the healthy population aged 1-19 years in Harbin, China.

Methods: Random sampling was performed to select 1 203 healthy individuals aged 1-19 years in Harbin. According to age, they were divided into ≥1 years group (n=240), ≥4 years group (n=396), ≥7 years group (n=364) and 14-19 years group (n=203).

Local unitary classification of arbitrary dimensional multipartite pure states.

We propose a practical entanglement classification scheme for general multipartite pure states in arbitrary dimensions under local unitary equivalence by exploiting the high order singular value decomposition technique and local symmetries of the states. By virtue of this scheme, the method of determining the local unitary equivalence of n-qubit states proposed by Kraus is extended to the case for arbitrary dimensional multipartite states.

[Study on technological characters of anaerobic-aerobic bioreactor landfill].

A technology of anaerobic-aerobic landfill bioreactor aimed at reusing landfill site is studied, and it's based on landfill bioreactor technology. A set of stimulating equipment is designed, and the technology characters are studied. In the anaerobic period, technological conditions are controlled by the means of leachate recirculation.
