To understand the Invar anomalies, such as negative thermal expansion and spontaneous magnetization, we have applied our recently developed thermodynamic framework for a system with itinerant-electron magnetism to the ordered Fe3Pt. The framework has coherently predicted the finite temperature intermixing between the fully ferromagnetic (FM) configuration and the spin-flipping configurations (SFCs). We have also discovered a tri-critical point at which a high-temperature second-order phase transition, between the fully ordered FM phase and the paramagnetic phase which is disordered due to SFCs, becomes first order at low temperatures. 相似文献

The vasopressin V1b receptor (AVPR1B) gene has been shown to be closely associated with bipolar disorder and depression. However, whether it relates to positive social outcomes, such as empathy and prosocial behavior, remains unknown. This study explored the possible role of the AVPR1B gene rs28373064 in empathy and prosociality. A total of 256 men, who were genetically unrelated, non‐clinical ethnic Han Chinese college students, participated in the study. Prosociality was tested by measuring the prosocial tendencies of cognitive and emotional empathy using the Interpersonal Reactivity Index (IRI). The single nucleotide polymorphism (SNP), rs28373064, was genotyped using a polymerase chain reaction–restriction fragment length polymorphism (PCR‐RFLP) analysis. The results suggest that the AVPR1B gene rs28373064 is linked to emotional empathy and prosociality. The mediation analysis indicated that the effect of the AVPR1B gene on prosociality might be mediated by emotional empathy. This study demonstrated the link between the AVPR1B gene and prosociality and provided evidence that emotional empathy might mediate the relation between the AVPR1B gene and prosociality. 相似文献

Abstract A quasicrystalline Al-Fe phase has been formed by room-temperature ion mixing of AI-Fe multiple layers with no additional postannealing. The quasicrystalline phase was dispersed as grain in an amorphous matrix. The size of the grains was about 10-30nm, and the composition was determined to be Al80Fe20. The structure of the quasicrystalline phase was identified by calculating some 20 sharp diffraction rings in the selected-area diffraction pattern and found to be similar to that of the rapidly quenched AI-Mn quasicrystalline phase. 相似文献

The position of Dy in the unit cell of Bi2Sr2CaCu2Oy has been determined by a real-space method. This is compared with the reciprocal-space atom location by channelling-enhanced microanalysis (ALCHEMI) method. 相似文献

Metaphysics is a repeated act by way of “representation”; the instantaneous judgment is solidified, the inevitable conclusion
is made, and at the same time other possibilities are excluded. “Outside thinking” is a blow to the spiritual tradition of
metaphysics, which holds that “representation” will lead to a differential activity concerning the relationship between stranger
things. Such relationship follows a kind of “horizontal logic,” the latter discards the presupposition on the “origin” of
things, that is, it no longer presumes that this point or that point has greater privilege than “other points.” Things do
not develop from a central point. Rather, things are the result of innumerable “points” in cooperative relationships between
strangers. These cooperative relationships are arbitrary. In “horizontal logic,” many “starting points” or “spiritual T-points”
are used as substitutes for a unique “origin.” 相似文献

民国时期,甘宁青地区水旱和地震等自然灾害频仍,成为阻碍社会发展的重要因素。西方传教士在着力布道的同时,也密切关注该地区的自然灾害。传教士在第一时间深入灾区调查,以客观公正的眼光记述灾情,撰写了详细调查报告,发往外界,使外界对灾情有了明确的认识;同时,传教士身体力行参与到灾区的救济当中,他们将各地捐来的款项用以工代赈、兴办贫儿院的方式救济灾民,使灾区得到部分复苏。不可否认,传教士积极参与救灾有笼络人心、扩大教会影响、劝导民众入教之目的,但传教士秉持基督博爱惠施的精神,努力赈灾所取得的成效应予以肯定。 相似文献

Study of the sex ratio of mortality rates among three categories of long-term psychiatric inpatients suggests a trend toward equalization of death rates between the sexes by specific cause of death, given the constant inpatient environment. The most dramatic example of this equalization was the virtual parity of death rates for ischemic heart disease among younger schizophrenic patients of both sexes in contrast to a three- to fourfold male excess in the general population. An exception to this equalization was seen for neoplasm deaths, which showed a female excess in all three patient groups in contrast to the male excess seen in the general population. Further study of chronically hospitalized psychiatric patients seems indicated to delineate patterns of death associated with biologic variation in a relatively constant environment. 相似文献

There has recently been much interest in computerized adaptive testing (CAT) for cognitive diagnosis. While there exist various item selection criteria and different asymptotically optimal designs, these are mostly constructed based on the asymptotic theory assuming the test length goes to infinity. In practice, with limited test lengths, the desired asymptotic optimality may not always apply, and there are few studies in the literature concerning the optimal design of finite items. Related questions, such as how many items we need in order to be able to identify the attribute pattern of an examinee and what types of initial items provide the optimal classification results, are still open. This paper aims to answer these questions by providing non‐asymptotic theory of the optimal selection of initial items in cognitive diagnostic CAT. In particular, for the optimal design, we provide necessary and sufficient conditions for the Q ‐matrix structure of the initial items. The theoretical development is suitable for a general family of cognitive diagnostic models. The results not only provide a guideline for the design of optimal item selection procedures, but also may be applied to guide item bank construction. 相似文献

Microstructure and deformation mechanisms at a nanoindentation in the lamellar colony of high Nb containing TiAl alloy have been studied using the focused ion beam and the transmission electron microscopy. Considerable deformation twins are observed around the nanoindentation, and a strain gradient is generated. A continuous change in the bending angle of the lamellar structure can be derived, and a strain-induced grain refinement process is observed as various active deformations split the γ grains into subgrains. In addition to all possible deformation mechanisms (ordinary dislocation, super-dislocation and deformation twining) activated due to the heavy plastic deformation, a 6-layer hexagonal (6H) long-period stacking ordered structure is identified for the first time near the contact zone and is thought to be closely related to the glide of partial dislocations. 相似文献
