Effect of Trust in Metaverse on Usage Intention through Technology Readiness and Technology Acceptance Model
The fourth industrial revolution enhanced the development of information technology in all fields and opened up possibilities. A lot of attention is focused on the future possibilities opened up by the metaverse, the core of information technology. Metaverse will have a big impact on reality and the near future. Metaverse is a virtual world that fuses physical and digital reality. Various commerce such as healthcare, instruction, business, and land are foundation to utilize metaverse knowledge in their regular work. There is a series of processes in the stage where newly developed technology is introduced to general users. In order for a new technology to become a user-friendly technology, it is necessary to verify the technology. It can be said that it is hard to derive the operator\u27s usage intention in a state where user trust for new technology is not verified. In the metaverse environment, it is necessary to first verify the trust for new technologies. This study is expected to understand usage intention through the process of checking trust in metaverse, and to become basic data for the popularization of metaverse knowledge. The meaning of this research is to inspect the influence relationship of trust in metaverse on usage intention through Technology Readiness (TR) and Technology Acceptance Model (TAM). Statistical package (SPSS23.0) was used for basic numerical examination of the questionnaire. Hypothesis test was performed using the structural equation package Smart PLS 3.0. Discriminant validity and concentration validity of the questionnaire were verified. As parameters that trust in metaverse effects, TR and TAM were set. As factors constituting TR, it was separated into optimism, innovativeness, discomfort, and insecurity. The TAM is separated into perceived usefulness and perceived ease of use. The outcomes of the study are as follows. First, trust in metaverse had a significant effect on TR. Second, TR was partially adopted in the TAM. Innovativeness and perceived usefulness had no significant effect. Third, TAM significantly influences usage intention. Fourth, perceived ease of use did not significantly influence perceived usefulness
Fundamental Structural Constraint of Random Scale-Free Networks
We study the structural constraint of random scale-free networks that
determines possible combinations of the degree exponent and the upper
cutoff in the thermodynamic limit. We employ the framework of
graphicality transitions proposed by [Del Genio and co-workers, Phys. Rev.
Lett. {\bf 107}, 178701 (2011)], while making it more rigorous and applicable
to general values of kc. Using the graphicality criterion, we show that the
upper cutoff must be lower than for , whereas
any upper cutoff is allowed for . This result is also numerically
verified by both the random and deterministic sampling of degree sequences.Comment: 5 pages, 4 figures (7 eps files), 2 tables; published versio
Nonlocal quantum state ensembles and quantum data hiding
We consider the discrimination of bipartite quantum states and establish a
relation between nonlocal quantum state ensemble and quantum data hiding
processing. Using a bound on optimal local discrimination of bipartite quantum
states, we provide a sufficient condition for a bipartite quantum state
ensemble to be used to construct a quantum data-hiding scheme. Our results are
illustrated by examples in multidimensional bipartite quantum systems.Comment: 11 pages, 4 figure
Entanglement witness and multipartite quantum state discrimination
We consider multipartite quantum state discrimination and show that the
minimum-error discrimination by separable measurements is closely related to
the concept of entanglement witness. Based on the properties of entanglement
witness, we establish some necessary and/or sufficient conditions on
minimum-error discrimination by separable measurements. We also provide some
conditions on the upper bound of the maximum success probability over all
possible separable measurements. Our results are illustrated by examples of
multidimensional multipartite quantum states. Finally, we provide a systematic
way in terms of the entanglement witness to construct multipartite quantum
state ensembles showing nonlocality in state discrimination.Comment: 13 pages, 1 figure. arXiv admin note: substantial text overlap with

Entanglement Teleportation Based on Noisy Port Based Teleportation
Port-based teleportation(PBT) is one of variation of the original quantum
teleportation, and is being used and explored in quantum information processing
due to its various applications. This work delves into the realm of PBT,
specifically when the resource state is subjected to Pauli noise from the
environment. We characterise the noisy PBT protocol by describing as Kraus
representation. Furthermore, we investigate the entanglement teleportation
using the noisy PBT. We derive and investigate upper and lower bounds for the
measure of entanglement of teleported unknown state. To achieve the above
results, we have investigated the entanglement of two-qubit bipartite states
through local Pauli channel. We derived the order of entanglement of two qubit
states is preserved through Pauli channel, and also the boundaries of reduced
entanglement through this channel.Comment: 10 pages, 4 figure
Imprinting of an evolutionarily conserved antisense transcript gene APeg3
APeg3 is an antisense transcript gene of Peg3, which has been recently identified from rat brain. Careful analyses of EST databases indicated that a homologous transcript also exists in other mammalian species, including mouse, cow and human. 5′-and 3′-RACE experiments have subsequently identified a 900-bp cDNA sequence of APeg3 from mouse brain. Mouse APeg3 is localized in the 3′UTR of Peg3 with an intronless genomic structure. The expression of mouse APeg3 is derived mainly from the paternal allele, indicating the imprinting of this antisense transcript gene in brain. Strand-specific RNA analyses also revealed the expression of both human and cow APEG3 in adult brains. In sum, our study confirms that the mammalian PEG3 locus harbors an antisense transcript gene displaying paternal allele-specific expression, and the evolutionary conservation further suggests potential roles of this transcript gene for the function of this imprinted domain
