The site preference, electronic structure, and magnetism of Heusler alloy Fe2RuSi are investigated theoretically and experimentally. The magnetic and electronic properties of Heusler alloys are strongly related to the atomic ordering and site preference in them. Usually, the site preference of the transition metal elements is determined by the number of their valence electrons. However, the recent results suggest that some new possible factors such as atomic radius should also be considered.doi:10.7498/aps.65.147102 fatcat:fh2guzdningp7h26kgcbjp53ie

First-principles calculations suggest that Ru atom prefers entering sites A and C in the lattice. In ground state, the most stable structure is of XA type, in which Fe and Ru atoms occupy A and C sites, respectively and the second stable structure is L21B type, in which Fe and Ru atoms occupy A and C sites randomly. With Ru atom entering into the B site, the total energy increases rapidly. Thus there is still a strongly preferable occupation of Ru though Fe and Ru atom are isoelectronic. This confirms that the "valence electrons rule" may be not enough to determine the site preference of the transition metal element in Heusler alloy. The preferable occupation of Ru atom in Fe2RuSi can be explained from the electronic structure. It is found that in the XA DOS, there is strong hybridization between the electrons of the nearest Ru and Si or Fe (B) atom. However, in the high energy L21 structure the hybridization between Ru and the nearest Fe (A, C) is weak, which reduces its phase stability. This is confirmed further by the charge density difference calculation. Single phase Fe2RuSi with a lattice parameter of 5.79 Å is synthesized successfully. Comparing the superlattice reflections ( 111 ) and ( 200 ) in the experimental XRD pattern with those in the simulated patterns for different structures, we find that Fe2RuSi crystallizes in L21B structure rather than the most stable XA one at room temperature, which mainly originates from the contribution of mixed entropy to the free energy, and its caused atomic disorder at high temperatures. This disorder can be retained during the cooling procedure, while it does not influence the conclusion that Ru atom prefers the (A, C) sites in Fe2RuSi strongly. Finally, the saturation magnetization Ms at 5 K is 4.87 µB/f.u., which agrees well with the theoretical result. The large total magnetic moment mainly comes from the contributions of Fe, especially Fe magnetic moments on B sites.

One of the most noticeable characteristics of security issues is the prevalence of "Security Asymmetry". The safety of production and even the lives of workers can be jeopardized if risk factors aren't detected in time. Today, object detection technology plays a vital role in actual operating conditions. For the sake of warning danger and ensuring the work security, we propose the Attention-guided Feature Fusion Network method and apply it to the Helmet Detection in this paper.

From objects of finite sizes to a wider range of sizes, the proposed method achieves "symmetry" in the sense of detection.

We define genuine total, classical and quantum correlations in tripartite systems. The measure we propose is based on the idea that genuine tripartite correlation exists if and only if the correlation between any bipartition does not vanish. We find in a symmetrical tripartite state, for total correlation and classical correlation, the genuine tripartite correlations are no less than pair-wise correlations. However, the genuine quantum tripartite correlation can be surpassed by the pair-wisearXiv:1206.1908v1 fatcat:wlmmrnb25ffqxj55yxaux5etga

Energy crisis is one of the major problems that China is facing, and energy materials chemistry plays an important role in addressing this critical issue.

AbstractNanoclusters (NCs) bridge the gap between atoms and nanomaterials in not only dimension but also physicochemical properties. Precise chemical and structural control, as well as clear understanding of formation mechanisms, have been important to fabricate NCs with high performance in optoelectronics, catalysis, nanoalloys, and energy conversion and harvesting.

Moreover, the purposely-embedded dual luminescent probes offer great superiority for in situ and precise tracking of tiny structural variations and energy transfer pathways within complex nanoarchitectures.
Chemical study on the ethanolic extract generated from the aerial parts of Croton kongensis led to the isolation of three new 8,9-seco-ent-kaurane diterpenoids, kongeniods A‒C (1‒3), together with seven known analogs (4–10). The structures of these compounds were assigned by spectroscopic data analysis. The vitro cytotoxic tests showed that compounds 1–3 exhibited strong activities against HL-60 cell lines with IC50 values of 0.47, 0.58, and 1.27 μM, respectively.doi:10.6084/m9.figshare.5398375 fatcat:m6pwod2p5fddzicamosftwf2le

Many important decision-making processes in transportation planning and engineering involve repetitive computation of network performance measured by total network delay, throughput, network efficiency, and other measures. The computational complexity imposed by repetitive evaluation of these measures, especially under user equilibrium conditions, is a serious obstacle to timely decision making in network-related problems. This study applies associative memory techniques, which are conceptually and computationally simple, to quick estimation of these performance measures. The results of the numerical experiments are encouraging, and the relative error on average was found to be less than 2%. Furthermore, the applicability of this approximation method to bilevel network problems, a class of important but complex problems, is explored through a study of the network recovery problem, which seeks a quick and effective repair strategy for disturbed networks following natural or human-induced disasters. Transportation engineering and planning studies usually require that individual transportation facilities in a region be studied as a whole system. Because of its spatial feature, a transportation system is often modeled as a network consisting of nodes and various links connecting these nodes. Standard network performance measures used in the field of transportation include total travel time, network efficiency, total throughput, and other measures. Almost every transportation system study involves evaluation of network performance criteria. To name a few, examples include cost-effectiveness analysis of various network improvement policies, loss assessment of natural and humaninduced disasters (1), network resilience studies (2), and as part of the solution to a large number of important bilevel problems such as the network recovery problem (NRP) (3, 4) . However, resources required to compute these performance measures for networks of realistic size may be quite extensive, in spite of significant developments in theory and computation (5-7), especially if traffic is assumed to be in a user equilibrium (UE) condition. The Franke-Wolfe algorithm, for instance, required about 150 s of CPU time on a personal computer to solve one UE traffic assignment problem for highway network of the San Francisco Bay area in California, with about 1,120 zones and 10,647 nodes. The computational burden may not seem to matter if only a single computation is needed, but it
