The codes of matter and their applications

Science Bulletin 2015年第19期60卷 1661-1673页

作者： xiao-lin wang Spintronic and Electronic Materials Group Institute for Superconducting and Electronic Materials Australia Institute for Innovative Materials University of Wollongong

The elements in the periodic table are the building blocks used to form substances with different compositions. Nevertheless, it is the properties of substances that are decisive for their existence and practical applications. Searching for new class of materials with exotic properties has always been challenging because of the complexity of both the theoretical and the experimental approaches developed so far. Here, we propose that the three ubiquitous and paramount attributes of all existing matter charge(Q), spin(S) or rotational motion, and linear motion(K) can be used to account for the formation of different types of matter/materials and their properties that have been or will be known to us. The three attributes or original codes can produce six primary codes which can further produce another sixty codes. The physical meanings represented by each code are unlocked. The table consisting of the 60 codes is introduced as the table of properties of codes of matter. We demonstrate that these codes can be used as building blocks to form new properties and new materials. Many new types of quasiparticles and new classes of materials with exotic properties of Q, S and K are predicted. Their possible experimental realizations are proposed. The possible applications of the codes of matter in other fields such as elementary particles, photonics and chemistry are briefly discussed. We know that there should be more new materials and new electronic, spin and photonic states to be discovered, but we do not know what they are. The codes of matter clearly reveal to us how many and what they are and how easily we can recognize what they are. Experimental and theoretical exploration for new forms of matter, new quasiparticles, or new electronic and spin states, or new states of photon or properties of light, as well as macroscopic entities with exotic properties represented by the codes of matter, is imminent.

Dirac spin-gapless semiconductors:promising platforms for massless and dissipationless spintronics and new(quantum) anomalous spin Hall effects

引用

National Science Review 2017年第2期4卷 252-257页

作者： xiao-lin wang Spintronic and Electronic Materials Group Institute for Superconducting and Electronic MaterialsAustralian Institute for Innovative MaterialsUniversity of Wollongong

It is proposed that the new generation of spintronics should be ideally massless and dissipationless for the realization of ultra-fast and ultra-low-power spintronic devices. We demonstrate that the spin-gapless materials with linear energy dispersion are unique materials that can realize these massless and dissipationless states. Furthermore, we propose four new types of spin Hall efects that consist of spin accumulation of equal numbers of electrons and holes having the same or opposite spin polarization at the sample edge in Hall efect measurements, but with vanishing Hall voltage. hese new Hall efects can be classiied as(quantum) anomalous spin Hall efects. he physics for massless and dissipationless spintronics and the new spin Hall efects are presented for spin-gapless semiconductors with either linear or parabolic dispersion. New possible candidates for Dirac-type or parabolic-type spin-gapless semiconductors are proposed in ferromagnetic monolayers of simple oxides with either honeycomb or square latices.

Exact Inference for Joint Type-I Hybrid Censoring Model with Exponential Competing Risks Data

引用

Acta Mathematicae Applicatae Sinica 2017年第3期33卷 645-658页

作者： SONG MAO Yi-min SHI xiao-lin wang Department of Economics and Management Shanxi UniversityTaiyuan 030006China Department of Applied Mathematics Northwestern Polytechnical UniversityXi'an 710072China 78020 Unit Kunming 655000China

Assuming that the failure time under different risk factors follows the independent exponential distribution, a joint model under Type-I hybrid censoring is addressed in detail. Based on the Maximum likelihood estimates （MLEs） of unknown parameters, we obtain exact distributions of MLEs by using the moment generating function （MGF）. Confidence intervals （CIs） of parameters are constructed through both the exact method and the parametric bootstrap method. Then we compare the performances of different methods by Monte Carlo simulations. Finally, the validity of the proposed models and methods are demonstrated by a numerical example.

World Journal of Gastroenterology 1999年第6期5卷 488-491页

作者： wang Xiu Jie, YUAN Shu Lan, xiao lin, wang Xu Hua and wang Chao Jun Institute of Cancer Research First University Hospital West China University of Medical Sciences Chengdu 610041 Sichuan Province China Department of Oncology China

AIM To investigate the activation, expression of c src gene and its role in the carcinogenetic process of human cardia adenocarcinoma (CA). METHODS Fifty six cases of CA, 34 cases of normal, 36 cases of protiferative epithelia adjacent to carcinoma, and 20 cases of lymph node metastases of CA were studied for PP60 c src , the expression product of c src gene immunohistochemically by using the specific monoclonal antibody, Mab327. RESULTS The positive rates of PP60 c src in the normal epithelia, protiferative epithelia, CA and lymph node metastases were 29 4% (10/*!34), 94 4% (34/*!36), 71 4% (40/*!56) and 60 0% (12/*!20) , respectively, among them, the differences of the positive rates were statistically significant ( P <0 01) . The expression levels of PP60 c src in CA and proliferative epithelia were significantly higher than that in the normal epithelia ( P <0 01) . The PP60 c src positive rates in the papillary, tubular, poorly differentiated and mucous adenocarcinoma were 75 0% (6/*!8) , 81 8% (18/*!22) , 50 0% (10/*!20) and 100 0% (6/*!6) , respectively, whereas those of tubular and mucous adenocarcinomas were significantly higher than those of papillary and poorly differentiated adenocarcinomas ( P <0 05) , and the PP60 c src expression levels of tubular and mucous adenocarcinomas were also significantly higher than those of papillary and poorly differentiated adenocarcinomas ( P <0 01) . CONCLUSION The activation and expression of c src gene are associated with the initiation and development of human CA; the protein amount of PP60 c src increased during the process of carcinogenesis; and PP60 c src expression is also related to lymph node metastases.

A novel kind of fully bio-based PSAs we re obtained through the curing reaction between two components derived from the plant oils:carboxyl-terminated polyricinoleate(PRA) fro m the castor oil and epoxidized soybean oil(ESO).The get content,glass transition temperature(Tg),rheological behavior,tensile strength,creep resistance and 180° peel strength of the PSAs were feasibly tailored by adjusting the component ratio of ESO to *** low cross-linking level,the PSAs behaved like a viscous liquid and did not possess enough cohesiveness to sustain the mechanical stress during peeling,The PSAs cross-linked at or near the optimal stoichiometric conditions displayed an adhesive(interfacial) failure between the substrate and the adhesive layer,which were associated with the lowest adhesion *** PSAs with the dosage amount of ESO ranging from 10.20 wt% were tacky and flexible,which exhibited 1800 peel strength ranging from 0.4~2.3 N/cm;and could be easily removed without any residues on the *** process for the preparation of the fully bio-based PSAs was environmentally friendly without using any orga nic solve nt or other toxic chemical,herein showing the great potential as sustainable materials.
