Research on the Construction of Evaluation Index System for Teaching Innovation Teams of Vocational College Teachers Based on CIPP Model

Fangrong Wu, Zengqiang Lei

The construction of innovative teaching teams for teachers is an important measure to deepen vocational education reform and enhance teachers' abilities and qualities. This study aims to address the problems of vague goals, lack of processes, and insufficient quantification of achievements in …

A review of research on federated learning in the field of medical image processing

Zengqiang Lei, Fangrong Wu, Jingyan Zhang

In the field of medical image processing, data sharing is difficult to achieve due to privacy protection issues, and there are also risks such as high communication overhead and privacy leakage in multi center electronic case data. Federated learning, as a method …

Measurements of the electric and magnetic form factors of the neutron for time-like momentum transfer

BESIII Collaboration, M. Ablikim, M. N. Achasov, P. Adlarson et autres

We present the first measurements of the electric and magnetic form factors of the neutron in the time-like (positive $q^2$) region as function of four-momentum transfer. We explored the differential cross sections of the reaction $e^+e^- \rightarrow \bar{n}n$ with data collected with …

Study of $e^+e^-\rightarrowΩ^{-}\barΩ^{+}$ at center-of-mass energies from 3.49 to 3.67 GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov, P. Adlarson et autres

Using data samples of $e^+e^-$ collisions collected with the BESIII detector at eight center-of-mass energy points between 3.49 and 3.67 GeV, corresponding to an integrated luminosity of 670 pb$^{-1}$, we present the upper limits of Born cross sections and the effective form …
