Video Game Music and Cultural Dissemination
As the internationally one of the most-played multiplayer online battle arena (MOBA) game, Honour of Kings (HoK) has created a unique cultural phenomenon apart from its gaming appeal. HoK weaves its aesthetically-pleasing game character, plot, scene, background, and music with Chinese traditional culture (CTC) elements. This contributes to popularise CTC across the world and Chinese music works, accordingly. Therefore, this article starts with the CTC elements and music works in HoK and explores the effect of Video Game Music (VGM) on cultural dissemination. Further, it explores theĀ new ways and trends of traditional culture transmission. Lastly, this article comprehensively discusses the current problems and solutions of cultural and musical promulgation in games. ItĀ canĀ be explained that the effort in terms of VGM composition would contribute to the HoK game develop better. These findings can also provide research ideas for developing VGM in Chinese style
Magnetic field-induced quantum phase transitions in a van der Waals magnet
Exploring new parameter regimes to realize and control novel phases of matter
has been a main theme in modern condensed matter physics research. The recent
discovery of 2D magnetism in nearly freestanding monolayer atomic crystals has
already led to observations of a number of novel magnetic phenomena absent in
bulk counterparts. Such intricate interplays between magnetism and crystalline
structures provide ample opportunities for exploring quantum phase transitions
in this new 2D parameter regime. Here, using magnetic field and temperature
dependent circularly polarized Raman spectroscopy of phonons and magnons, we
map out the phase diagram of CrI3 that has been known to be a layered AFM in
its 2D films and a FM in its 3D bulk. We, however, reveal a novel mixed state
of layered AFM and FM in 3D CrI3 bulk crystals where the layered AFM survives
in the surface layers and the FM appears in deeper bulk layers. We then show
that the surface layered AFM transits into the FM at a critical magnetic field
of 2 T, similar to what was found in the few layer case. Interestingly,
concurrent with this magnetic phase transition, we discover a first-order
structural phase transition that alters the crystallographic point group from
C3i to C2h and thus, from a symmetry perspective, this monoclinic structural
phase belongs to the 3D nematic order universality class. Our result not only
unveils the complex single magnon behavior in 3D CrI3, but also settles down
the puzzle of how CrI3 transits from a bulk FM to a thin layered AFM
semiconductor, despite recent efforts in understanding the origin of layered
AFM in CrI3 thin layer, and reveals the intimate relationship between the
layered AFM-to-FM and the crystalline rhombohedral-to-monoclinic phase
transitions. These findings further open up opportunities for future 2D
magnet-based magneto-mechanical devices
Magnetic Exciton-Polariton with Strongly Coupled Atomic and Photonic Anisotropies
Anisotropy plays a key role in science and engineering. However, the
interplay between the material and engineered photonic anisotropies has hardly
been explored due to the vastly different length scales. Here we demonstrate a
matter-light hybrid system, exciton-polaritons in a 2D antiferromagnet, CrSBr,
coupled with an anisotropic photonic crystal (PC) cavity, where the spin,
atomic lattice, and photonic lattices anisotropies are strongly correlated,
giving rise to unusual properties of the hybrid system and new possibilities of
tuning. We show exceptionally strong coupling between engineered anisotropic
optical modes and anisotropic excitons in CrSBr, which is stable against
excitation densities a few orders of magnitude higher than polaritons in
isotropic materials. Moreover, the polaritons feature a highly anisotropic
polarization tunable by tens of degrees by controlling the matter-light
coupling via, for instance, spatial alignment between the material and photonic
lattices, magnetic field, temperature, cavity detuning and cavity
quality-factors. The demonstrated system provides a prototype where atomic- and
photonic-scale orders strongly couple, opening opportunities of photonic
engineering of quantum materials and novel photonic devices, such as compact,
on-chip polarized light source and polariton laser
"Extraordinary" Phase Transition Revealed in a van der Waals Antiferromagnet
While the surface-bulk correspondence has been ubiquitously shown in
topological phases, the relationship between surface and bulk in Landau-like
phases is much less explored. Theoretical investigations since 1970s for
semi-infinite systems have predicted the possibility of the surface order
emerging at a higher temperature than the bulk, clearly illustrating a
counterintuitive situation and greatly enriching phase transitions. But
experimental realizations of this prediction remain missing. Here, we
demonstrate the higher-temperature surface and lower-temperature bulk phase
transitions in CrSBr, a van der Waals (vdW) layered antiferromagnet. We
leverage the surface sensitivity of electric dipole second harmonic generation
(SHG) to resolve surface magnetism, the bulk nature of electric quadrupole SHG
to probe bulk spin correlations, and their interference to capture the two
magnetic domain states. Our density functional theory calculations show the
suppression of ferromagnetic-antiferromagnetic competition at the surface
responsible for this enhanced surface magnetism. Our results not only show
unexpected, richer phase transitions in vdW magnets, but also provide viable
ways to enhance magnetism in their 2D form
Alterations of the gut microbiota associated with the occurrence and progression of viral hepatitis
BackgroundGut microbiota is the largest population of microorganisms and is closely related to health. Many studies have explored changes in gut microbiota in viral hepatitis. However, the correlation between gut microbiota and the occurrence and progression of viral hepatitis has not been fully clarified.MethodsPubMed and BioProject databases were searched for studies about viral hepatitis disease and 16S rRNA gene sequencing of gut microbiota up to January 2023. With bioinformatics analyses, we explored changes in microbial diversity of viral hepatitis, screened out crucial bacteria and microbial functions related to viral hepatitis, and identified the potential microbial markers for predicting risks for the occurrence and progression of viral hepatitis based on ROC analysis.ResultsOf the 1389 records identified, 13 studies met the inclusion criteria, with 950 individuals including 656 patient samples (HBV, n = 546; HCV, n = 86; HEV, n = 24) and 294 healthy controls. Gut microbial diversity is significantly decreased as the infection and progression of viral hepatitis. Alpha diversity and microbiota including Butyricimonas, Escherichia-Shigella, Lactobacillus, and Veillonella were identified as the potential microbial markers for predicting the risk of development of viral hepatitis (AUC>0.7). Microbial functions including tryptophan metabolism, fatty acid biosynthesis, lipopolysaccharide biosynthesis, and lipid metabolism related to the microbial community increased significantly as the development of viral hepatitis.ConclusionsThis study demonstrated comprehensively the gut microbiota characteristics in viral hepatitis, screened out crucial microbial functions related to viral hepatitis, and identified the potential microbial markers for predicting the risk of viral hepatitis
