Regional Design Attempts of China-aid Stadiums
Since the 1960s, China has exported a large number of foreign aid buildings to numerous recipient regions, initially as a member of the socialist camp spreading their post-war influence on developing countries, then as catalyzer of diplomacy and economic development. Among these constructions are a considerable proportion of stadiums. Because of their landmark effect and lasting time of use, these oversea stadiumsstandoutfromothertypesofChina-aidbuildings.Fromneighboringcountries in Asia to brotherhood countries in Africa, Latin America and Oceania, these largescale projects are located in different and complex geographical and cultural contexts. However, most of these projects were designed by Chinese architects from domestic design institutions. The integration of these buildings into the local environment and urban context becomes a significant issue for architectural design. Through detailed analysis of the representative case projects, and interviewing of people involved in the design and management process, we aim to explore and discuss regional design attempts and common methods used by Chinese architects when designing these cross-border stadiums, so as to provide reference for architectural design of this category in the future
1-Benzoyl-3-(5-quinolyl)thiourea
The title compound, C17H13N3OS, was obtained by the reaction of benzoyl chloride, ammonium thiocyanate and 5-aminoquinoline in the presence of polyethyleneglycol-400 (PEG-400) as a phase-transfer catalyst. The compound crystallized as discrete molecules linked by N—H⋯N and C—H⋯N hydrogen bonds involving all the potential donors, generating sheets parallel to (100). An intramolecular N—H⋯O bond is also present
(μ-Ethane-1,1,2,2-tetracarboxylato)bis[tetraaquamanganese(II)]
In the centrosymmetric title molecule, [Mn2(C6H2O8)(H2O)8], the MnII atom is in an octahedral environment coordinated by six O-atom donors from water molecules and ethane-1,1,2,2-tetracarboxylate ligands. The crystal structure features a three-dimensional hydrogen-bonding network based on a strong and distinctive pattern of O—H⋯O hydrogen-bonding interactions

Degenerate Rabi spectroscopy of the Floquet engineered optical lattice clock
Simulating physics with large SU(N) symmetry is one of the unique advantages
of Alkaline-earth atoms.Introducing periodical driving modes to the system may
provide more rich SU(N) physics that static one could not reach. However,
whether the driving modes will break the SU(N) symmetry is still lack of
discussions. Here we experimentally study a Floquet engineered degenerate Sr-87
optical lattice clock (OLC) by periodically shaking the lattice. With the help
of Rabi spectroscopy, we find that the atoms at different Zeeman sublevels are
tuned by the same driven function. Meanwhile, our experimental results suggest
that uniform distribution among the sublevels will not change despite the
driving. Our experimental demonstrations may pave the way to implementation of
FE on tailoring the SU(N) physics in OLC system
