Abstract： The awe is though as a complex awe experience, even a self-transcendent emotion, caused by something mysterious, vast and beyond the current cognitive schema. The psychological research of awe has recently received great attention, but the nature of awe or the psychological mechanism is still unclear. To address the scientific question of “what is the psychological process of awe”, the existing awe-related literature is reviewed and a Psychological Model of Awe is proposed to explain the psychological process of awe and its cognitive neural mechanism on the basis of clarifying the evolution of the concept of aw, related theoretical development and empirical research of awe. It has been discovered that the generation of awe involves the psychological processes including expectation estimate, outcome evaluation and self-transcendent. Vastness and the need for accommodation are the two core factors of awe which also has two dimensions including internal and external vastness, and positive and negative affection. Future research should focus on the development of awe-related assessment, verification of awe theory and comparative analysis of awe behavior in different cultural people by carrying out multi-disciplinary basic and clinical research.

Abstract： The successful memorisation of similar words is critical for individuals’ vocabulary acquisition. Previous studies have found that individuals perform significantly better in an immediate serial memory test for dissimilar words than similar words. However, the memory advantage for dissimilar words in those studies was mainly based on the comparison of two sets of different learning materials (i.e., similar and dissimilar words). Therefore, whether similar words are memorised better in a similar chunking condition (similar words are successively presented) or dissimilar chunking condition (similar words are alternately presented by other dissimilar words) is unclear.To address the above question, we performed four experiments in this study, in which within-subject design and study-test paradigm were used. Experiment 1A aims to explore the effects of chunking strategy on the memory of similar words. In this experiment, two matched sets of similar English pseudowords were used for the similar and dissimilar chunking conditions, respectively. In the similar chunking condition, similar words were successively presented, whereas in the dissimilar chunking condition, similar words were alternately presented with other dissimilar words. Participants were instructed to memorise the words during the study phase. A recognition memory test was administered one hour after the study phase. Experiment 1B aims to investigate the memory advantage of the dissimilar chunking condition for long-term retention. Experimental materials and tasks were the same with those of Experiment 1A, but the interval between study and test was prolonged to one week. Experiment 2 used Deese-Roediger-McDermott (DRM) paradigm to examine whether the dissimilar chunking strategy facilitated the memory of similar words by improving the memory of individual words or enhancing the memory of shared parts across similar words. Experiment 3 included unfamiliar Korean characters as materials to further disentangle the contributions of visual and phonological similarities on the memory of similar words.Results show that: 1) Compared with the similar chunking strategy, the dissimilar chunking strategy show better memory performance on similar words, which can be maintained for at least one week. 2) The dissimilar chunking strategy improves the memory of similar words and results in a high false memory for similar lures. 3) The memory advantage for dissimilar chunking strategy is evident for phonologically similar words (i.e., English pseudowords) but not for visually similar words (i.e., Korean characters).The results suggest that the dissimilar chunking strategy improves the memorisation of phonologically similar words by enhancing the memory of common parts across similar words. In other words, the dissimilar chunking strategy may be an effective way to improve the memorisation of similar words. These findings have important implications for language learning and education.

Abstract： Spheroidal graphite (SG) cast iron is characterized by the presence of spherical graphite nodules distributed in the metallic matrix. The performance of castings is primarily dependent on the solidification microstructures. In this work, a two dimensional (2D) multi-phase cellular automaton (MCA) model previously proposed by the present authors is improved to simulate the microstructure evolution of SG cast iron during divorced eutectic solidification. The present model adopts a local solutal equilibrium approach to calculate the driving force for the growth of both graphite and austenite phases. The density difference between iron and graphite is also taken into account. The diffusion of solute in the simulation domain is calculated using a finite difference method (FDM). The present model is applied to simulate the evolution of microstructure and carbon concentration field during solidification for hypereutectic SG cast irons. The results show that the present model can reasonably describe the typical features of divorced eutectic solidification, involving the independent nucleation and growth of primary graphite and austenite dendrites in liquid, the competitive growth of adjacent graphite nodules, engulfment of graphite nodules by austenite dendrites, the isotropic growth of the austenite shells that envelop the graphite nodules, the austenite to graphite eutectic phase transition controlled by carbon diffusion through the solid austenite shell, and multiple graphite nodules encapsulated in each austenite grain at the end of eutectic solidification. The simulated volume fraction and average diameter for graphite nodules are compared reasonably well with the experimental data and level rule calculation. The interactive and competitive growth behavior between austenite dendrites and graphite nodules is studied in detail. It is found that the growth of a graphite nodule is promoted by the approaching austenite. However, after embedded by an austenite dendrite, the growth velocity of graphite decreases rapidly because of lower carbon diffusivity in austenite than that in liquid. In addition, the effect of cooling rate on the size of graphite nodules is also investigated. The results show that with cooling rate increasing, the size distribution of graphite nodules varies from two peaks to one peak, and the average diameter of nodules decreases. The simulation results compare reasonably well with the experimental data reported in literature, demonstrating the validity of the present model.

Abstract： Carrying out the optimal allocation of land use is aimed at promoting the scientific use of regional land resources and achieving carbon emission reduction targets. In this paper, the Fenhe River Basin is taken as the research area. Based on the data on land use and resistance factors in 2015 and 2020, the FLUS-MCR model and the carbon budget coefficient method are used to verify the accuracy of the model. Five simulation scenarios, such as low- carbon development priority, economic development priority, cultivated land protection priority, ecological protection priority, and natural development in 2030, are set up to compare the layout characteristics of land use types under different scenarios in the future, and an optimized layout scheme is proposed. The results showed that: (1) In 2020, the areas of four land use functional zoning of the prohibited, restricted, key, and optimized development zones in Fenhe River Basin were 2491.76 km2, 6445.99 km2, 16325 km2, and 14477 km2, respectively. The net carbon emission of the basin is 2002.46 × 104 t. The prohibited development zone is the carbon sink area of the basin, and the total carbon absorption is 0.76×104 t. The remaining three areas are carbon source areas, and the total carbon emission is 2003.22 × 104 t. (2) In 2030, the carbon balance of land use in each scenario from high to low is low- carbon development priority, ecological protection priority, cultivated land protection priority, natural development priority, and economic development priority. (3) In 2030, under different scenarios, in addition to the relatively reasonable land use structure of the prohibited development zone, the restricted development zone still needs to appropriately reduce the proportion of cultivated land and construction land in the area. To support the coordinated development of land use, production, living conditions, and ecological functions and to accomplish low-carbon land use goals, the key and optimal development zones should take arable grassland development into consideration.

Abstract： Cubic helimagnet FeGe has emerged as a class of skyrmion materials near room temperature that may impact future information technology. Experimentally identifying the detailed properties of skyrmion materials enables their practical application acceleratedly. Here we study the magnetic entropy change (MEC) of single crystalline FeGe in its precursor region and clarify its close relation to the critical exponents of a second-order phase transition in this area. The maximum MEC is found to be 2.86 J/kg.K for 7.0 T magnetic field change smaller than that of common magnetocaloric materials indicating the multiplicity and complexity of the magnetic structure phases in the precursor region. This result also implies that the competition among the multimagnetic phases can partly counteract the magnetic field driven force and establishes a stable balance. Based on the obtained MEC and the critical exponents, the exact Curie temperature of single crystalline FeGe under zero magnetic field is confirmed to be 279.1 K, higher than previously reported 278.2 K. This finding pave the way for reconstruction of FeGe phase diagram in the precursor region.

Abstract： The magnetic entropy change [ΔSM(T;H)] around the phase transition temperature TC is investigated by the scaling method for Fe0:5Co0:5Si, which exhibits a skyrmion phase below TC. The parameters of ΔSM(T;H) exhibit field dependent behaviors. The ΔSM(T;H) curves under high field can be well scaled into a single universal curve independent of external field and temperature. However, ΔSM(T;H) curves under low field become divergent just below TC, which indicates a characteristic of first-order transition. The scaling investigation of ΔSM(T;H) curves indicates that the phase transition in Fe0:5Co0:5Si is of a weak first-order type in low field region, while it is driven into a second-order one under high field. This weak first-order phase transition in low field region resembles that in typical skyrmion system MnSi which is caused by the critical fluctuation. The result suggests that critical fluctuation plays an important role in the phase transition and formation of skyrmion state.

Abstract： The magnetism of the single crystal Cr1=3NbS2, which exhibits chiral soliton lattice (CSL) state, is investigated. The magnetization displays strong magnetic anisotropy when the field is applied perpendicularly and parallel to the c-axis in low field region (H < HS, HS is the saturation field). The critical exponents of Cr1=3NbS2 are obtained as β = 0.370(4), γ = 1.380(2), and δ = 4.853(6), which are close to the theoretical prediction of three-dimensional Heisenberg model. Based on the scaling equation and the critical exponents, the H T phase diagram in the vicinity of the phase transition is constructed, where two critical points are determined. One is a tricrtical point which locates at the intersection between the CSL, forced ferromagnetic (FFM), and paramagnetic (PM) states. The other one is a critical point situated at the boundaries between CSL, helimagnetic (HM), and PM states.

Abstract： Critical phenomenon of the noncentrosymmetric Cr11Ge19, which exhibits an itinerant ferromagnetic ground state, is investigated by scaling of the magnetic entropy change [ΔSM(T;H)]. It is found that parameters #14;FWHM (the full width at half maximum), ΔSmax M (the maximum of the magnetic entropy change), and RCP (the relative cooling power) of ΔSM(T) are governed by the power law of critical exponents. With the critical exponents, ΔSM(T;H) curves are scaled into a universal curve independent of temperature and field, which suggests that the magnetic transition is of a second order type. The universal collapse of ΔSM(T;H) indicates that the critical behavior of Cr11Ge19 can be well described by the scaling laws for the critical phenomenon. Moreover, the ΔSM follows the power law of Hn with n(T;H) = dlnjΔSMj=dln(H). The temperature dependence of n values reach minimum at #24; 71.5 K. Based on the magnetic specific change ΔCp(T;H), the actual magnetic transition temperature is strictly determined as TC = 71:3 #6; 0:2 K for the single crystal Cr11Ge19.

Abstract： In this work, the resistivity and magnetization of Bi2Ir2O7 are investigated under hydrostatic pressure. At ambient pressure, the resistivity of Bi2Ir2O7 exhibits a metallic behavior with the decrease of temperature. When the pressure is applied, a metal-insulator phase transition at low temperature is induced under a pressure of #24; 0.48 GPa. The metal-insulator phase transition temperature (TMI ) increases linearly with pressure as dTMI/dP = 3.4 #6;0.3 K/GPa. The temperature dependence of resistivity [#26;(T)] in the pressure-induced insulating phase exhibits a thermal activation behavior (#26; = #26;0eΔE=kBT ), where the thermal activation energy (ΔE) increases monotonously with the pressure. Meanwhile, the magnetization is enhanced by the pressure, which indicates an enhancement of magnetic ordering. The results suggest that localization occurs due to the magnetic ordering induced by the pressure, which confirms the magneto-electronic coupling in Bi2Ir2O7

Abstract： The iso-spinel structural systems CuIr2S4 and MgTi2O4 exhibit phase transitions of the similar nature at #24; 230 K and #24; 260 K respectively, which are explained as an orbitally-induced Peierls phase transition. However, in this work, we uncover that applied pressure has opposite pressure effects on the phase transitions in CuIr2S4 and MgTi2O4. As pressure increases, the phase transition temperature (TMI ) for CuIr2S4 increases while that for MgTi2O4 decreases. In addition, the phase transition intensity becomes weaker for CuIr2S4 but gets stronger for MgTi2O4 under pressure. Our results indicate that the applied pressure suppresses the metallic phase in CuIr2S4, while enhances that in MgTi2O4. Combining the experimental observations with first-principle electronic structure calculations, we suggest that the opposite pressure effects in CuIr2S4 and MgTi2O4 originate from the different orbital ordering configurations (dxy, dyz/dxz) caused by different lattice distortions in these two systems. Our findings directly indicate that the interplay between the orbital and lattice degrees of freedom plays an important role in the orbitally-induced Peierls phase transition.

Abstract： The cubic B20 compound FeGe, which exhibits a near room temperature skyrmion phase, is one of the most promising candidate of the next generation spintronic devices. In this work, the critical behavior of the cubic FeGe is investigated by means of bulk dc-magnetization. We obtain the critical exponents (β = 0.336±0.004, γ = 1.352±0.003, and δ = 5.267±0.001), where the self-consistency and reliability are verified by the Widom scaling law and scaling equations. The magnetic exchange distance is found to decay as J(r) ~ r-4.9, which is close to the theoretical prediction of 3DHeisenberg model (r-5). The critical behavior of FeGe indicates a short-range magnetic interaction. Meanwhile, the critical exponents also imply an anisotropic magnetic coupling in this system.

Abstract： Dimensionality is one of the most important parameters in determination of the physical properties. Therefore, tuning of effective dimensionality is of significant importance for modulating the functionality of materials. In this work, we find that the spin-dimensionality can be changed by the Co-doing in Fe1_xCoxSi system. Investigation of the critical behavior shows that critical exponents for x = 0.3 agree with the three-dimensional (3D) Heisenberg model with fd : n = 3 : 3g (d is the spatial-dimensionality, and n is the spin-dimensionality). With the increase of Co-content, the critical exponents for x = 0.5 fulfill the 3D-XY model with fd : n = 3 : 2g, while those for x = 0.6 approach the 3D-Ising model with fd : n = 3 : 1g. These results indicate the lowering of the spin-dimensionality with the increase of Co-content in Fe1_xCoxSi. We suggest that the modulation of the spin-dimensionality in Fe1_xCoxSi should be resulted from the enhancement of the anisotropic magnetic interaction induced by the doping of Co.

Abstract： The transport property of chalcogenide spinel CuCr2Se4 with an itinerant ferromagnetic ground state can be modulated by doping of bromine, where the half-metallic state can be realized around x = 0.25 in CuCr2Se4−xBrx system. In this work, the single crystal CuCr2Se4−xBrx (x =0.25) with the cleave surface (111) plane has been investigated by the electron paramagnetic resonance (EPR) spectroscopy. The EPR results show that the in-plane magnetization is strong while the out-ofplane one is weak, which indicate that the spins are ferromagnetic ordered within the (111) plane. In addition, the isothermal EPR spectra in the ferromagnetic phase display that the spin coupling strength (λ) and crystal field (ΔCF ) depend on the rotation angle φ as relation λ/ΔCF / cos φ. Moreover, the peak-to-peak linewidth ΔHPP increases linearly with the decrease of temperature, which suggests that the spin-orbit coupling is enhanced linearly with temperature cooling.
