The emergence of a quantum spin liquid (QSL), a state of matter that can result when electron spins are highly correlated but do not become ordered, has been the subject of a considerable body of research in condensed matter physics [1,2]. Spin liquid states have been proposed as hosts for high-temperature superconductivity [3] and can host topological properties with potential applications in quantum information science [4]. The excitations of most quantum spin liquids are not conventional spin waves but rather quasiparticles known as spinons, whose existence is well established experimentally only in one-dimensional systems; the unambiguous experimental realization of QSL behavior in higher dimensions remains challenging.

Background: Thailand has made significant progress in malaria control efforts in the past decade, with a decline in the number of reported cases. However, due to cross-border movements over the past 5 years, reported malaria cases in Thailand have risen. The Malaria Infection Study in Thailand (MIST) involves deliberate infection of healthy volunteers with Plasmodium vivax malaria parasites, and the assessment of the efficacy of potential vaccine and drug candidates in order to understand acquired protection against malaria parasites.

In order to determine the influence of different factors on the CO huff-and-puff displacement effect, a CO huff-and-puff experiment was carried out with Chang 6 tight sandstone samples in Ordos Basin as the research object. Combined with nuclear magnetic resonance technology, the influences of injection pressure, cycle numbers and soaking time on the CO huff-and-puff effect were evaluated, and the optimal CO huff-and-puff parameters were optimized. The microscopic degree of crude oil production in different scale pores was quantitatively characterized.

The purpose of this research includes analyzing the interaction between online English learning motivations, digital readiness, academic engagement, self-regulated English learning attainment, and technology self-efficacy. These interactions were examined based on data gathered from learners in online English courses through the method of structural equation modeling. Analysis found that online English learning motivation has a significant impact on the learners' level of digital readiness and levels of academic engagement, thereby underlining its importance in getting learners ready for meaningful navigation of the digital environments with emphasis on specific academic tasks.
