A Virtual Reconstruction Methodology for Archaeological Heritage in East Asia – Practical Experience from the Re-relic Program in China
[EN] There is as much abundance of archaeological heritage in East Asia as there is diversity in the methodology for its reconstruction and representation. The Re-relic program in China recognizes the uniqueness of archaeological heritage in East Asia and has developed a tailored virtual reconstruction methodology that is both scientifically robust and popular for public interpretation. The theoretical consideration and field experience over the years shall contribute to the global understanding of the value and technique in virtual reconstruction, while testifying to the very principles of Seville Charter.[ES] El este de Asia se caracteriza tanto por su abundancia en patrimonio arqueológico como por su diversidad metodológica a la hora de llevar a cabo reconstrucciones y representaciones de dicho patrimonio. El programa Re-reliquia en China reconoce la singularidad del patrimonio arqueológico en el este de Asia y ha desarrollado una metodología adaptada para la reconstrucción virtual, científicamente sólida para la interpretación pública. El examen teórico y la experiencia de campo en los próximos años contribuirán a la comprensión global del valor y la técnica en la reconstrucción virtual, al prestar atención a los principios de la Carta de Sevilla.He, Y.; Gao, M.; Shang, J.

Identifying the Riemann zeros by periodically driving a single qubit
The Riemann hypothesis, one of the most important open problems in pure
mathematics, implies the most profound secret of prime numbers. One of the most
interesting approaches to solve this hypothesis is to connect the problem with
the spectrum of the physical Hamiltonian of a quantum system. However, none of
the proposed quantum Hamiltonians have been experimentally feasible.Here, we
report the first experiment to identify the first non-trivial zeros of the
Riemann zeta function and the first two zeros of P\'olya's fake zeta function,
using a novel Floquet method, through properly designed periodically driving
functions. According to this method, the zeros of these functions are
characterized by the occurrence of crossings of quasi-energies when the
dynamics of the system are frozen. The experimentally obtained zeros are in
excellent agreement with their exact values. Our study provides the first
experimental realization of the Riemann zeros, which may provide new insights
into this fundamental mathematical problem.Comment: 5 pages, 7 figure
A refined numerical investigation of a large equivalent shallow-depth underwater explosion
The large equivalent shallow-depth explosion problem is very significant in
the field of naval architecture and ocean engineering, as such explosions can
be used to attack and demolish ships and anti-ship missiles. In the current
work, a refined numerical study of the flow-field characteristics of a large
equivalent shallow-depth explosion is carried out using a self-developed
Eulerian finite element solver. Firstly, the numerical model is validated
against theoretical results and a small equivalent explosion test in a tank.
The numerical results are found to agree well with the theoretical and
experimental results. In the next step, the cavitation cut-off effect is added
to the underwater explosion model, and the cavitation phenomenon is
quantitatively analyzed through the flow-field pressure. In addition, the
dynamic characteristics of the bubble and water hump under various initial
conditions for different stand-off parameters are analyzed. The effect of
gravity on these physical processes is also discussed. The bubble pulsation
period, taking into account the free surface effect, is then quantitatively
studied and compared with Cole's experimental formula for an underwater
explosion. Overall, when the stand-off parameter > 2, the influence of the free
surface on the empirical period of the bubble is not significant. Our
investigation provides broad insights into shallow-depth underwater explosions
from theoretical, experimental, and numerical perspectives
