“…Judging by a picture of them, these wraps came in more or less identical batches consisting of two or three dozen slips, which probably no longer looked the way they did at the time of looting. 89 Dissolving the original codicological units would obviously allow them to be manipulated, such as by mixing fake slips among them. In addition, there is always the possibility that one corpus contains slips from more than one spot, leading to different dating.…”

Fakes and Forgeries of Written Artefacts From Ancient Mesopotamia to Modern China

View full text Add to dashboard Cite

In just a little more than two decades, from 1994 to 2015, seven public institutions in China acquired considerable numbers of unprovenanced bamboo-slip manuscripts. Following the economic upsurge the country experienced during this period, the art and antique market expanded rapidly. The artefacts that appeared on it did not always have a flawless history, though; some of them came from a flourishing industry producing and selling fakes, or even worse, from looted tombs. In the light of this development, it comes as no surprise that the authenticity of many of these manuscripts has been questioned. In order to understand how exactly judgements on the authenticity of these manuscripts were passed, it is necessary to go back to ancient and medieval ideas and practices. Traditional attitudes towards written artefacts are identified as determining modern approaches assessing and appreciating manuscripts from ancient China. […] calligraphy, valued for its capacity to embody in brushwork the mind and character of the individual artist, was more amenable to accurate and efficient replication than any other form of art. 1 Robert E. Harrist Jr. Manuscripts from ancient and medieval China have only been excavated in large quantities since the twentieth century. They are invaluable sources of information for scholars, and in collectors' eyes they are precious artefacts-if they 1 Harrist 2004, 32.

Thanks to Xiaomeng He for providing a collection of early Chinese legal stipulations related to faking and forging, from which I have drawn below. For simplicity's sake, I have used traditional characters here, even in cases where the source was produced in simplified characters.

Based on the magnetic monopoles(MMs) catalytic nuclear decay (RC effect), we propose five new models to discuss the limit of the MMs' flux and the cooling energy resources of the white dwarfs (WDs) by some observations from 13 RGB stars. We find that the number of MMs captured can reach the maximum value of $9.1223\times10^{24}$ when $m=10^{17}, n_B=5.99\times10^{31}, \phi=7.59\times10^{-26}$. The good agreement of our luminosities calculated for WDs with the observations shows that our model is rational due to RC effect by MMs. We obtain the new limit of the MMs' flux of $\xi=\phi\langle\sigma_m v_{\rm{T}}\rangle_{-28}\leq 9.0935\times10^{-13}$, and $\xi\leq 4.9950\times10^{-13}$ at $n_B=5.99\times10^{31}$ when $m=10^{15}, beta=9.4868\times10^{-3}$, and $m=10^{17}, \beta=10^{-3}$, respectively. Our results show that the RC effect could be preventing white dwarfs from cooling down into a stellar graveyard by keeping them hot. Our results will also provide a new idea for further research on the upper limit of MMs' flow.

“…According to the expression of the EC rate Equation (20) in the case without SMFs, we can derive a formula for EC rates in SMFs from one of the initial states to all possible final states. We can reference equations ( 20)-( 23) in Liu & Liu (2018a). It is given by…”

Using the theory of relativistic mean-field effective interactions, the influences of superstrong magnetic fields (SMFs) on electron Fermi energy, binding energy per nucleus and single-particle level structure are discussed in super-Chandrasekhar magnetic white dwarfs. Based on the relativistical SMFs theory model of Potekhin et al., the electron chemical potential is corrected in SMFs, and the electron capture (EC) of iron group nuclei is investigated by using the Shell-Model Monte Carlo method and Random Phase Approximation theory. The EC rates can increase by more than three orders of magnitude due to the increase of the electron Fermi energy and the change of single-particle level structure by SMFs. However, the EC rates can decrease by more than four orders of magnitude due to increase of the nuclei binding energy by SMFs. We compare our results with those of FFNs (Fuller et al.), AUFDs (Aufderheide et al.) and Nabi (Nabi et al.). Our rates are higher by about four orders of magnitude than those of FFN, AUFD and Nabi due to SMFs. Our study may have important reference value for subsequent studies of the instability, mass radius relationship, and thermal and magnetic evolution of super-Chandrasekhar magnetic white dwarfs.
