BACKGROUND Mild cognitive impairment(MCI)has a high risk of progression to Alzheimer’s *** disease is often accompanied by sleep disorders,and whether sleep disorders have an effect on brain function in patients with MCI is *** to explore the near-infrared brain function characteristics of MCI with sleep *** A total of 120 patients with MCI(MCI group)and 50 healthy subjects(control group)were *** subjects underwent the functional near-infrared spec-troscopy *** baseline data,Mini-Mental State Examination,Montreal Cognitive Assessment scale,fatigue severity scale(FSS)score,sleep parameter,and oxyhemoglobin(Oxy-Hb)concentration and peak time of functional near-infrared spectroscopy test during the task *** relationship between Oxy-RESULtS Compared with the control group,the FSS score of the MCI group was higher(t=11.310),and the scores of Pittsburgh sleep quality index,sleep time,sleep efficiency,nocturnal sleep disturbance,and daytime dysfunction were higher(Z=-10.518,-10.368,-9.035,-10.661,-10.088).Subjective sleep quality and total sleep time scores were lower(Z=-11.592,-9.924).the sleep efficiency of the MCI group was lower,and the awakening frequency,rem sleep latency period,total sleep time,and oxygen desaturation index were higher(t=5.969,5.829,2.887,3.003,5.937).the Oxy-Hb concentration at t0,t1,and t2 in the MCI group was lower(t=14.940,11.280,5.721),and the peak time was higher(t=18.800,13.350,9.827).In MCI patients,the concentration of Oxy-Hb during t0 was negatively correlated with the scores of Pittsburgh sleep quality index,sleep time,total sleep time,and sleep efficiency(r=-0.611,-0.388,-0.563,-0.356).It was positively correlated with sleep efficiency and total sleep time(r=0.754,0.650),and negatively correlated with oxygen desaturation index(r=-0.561)and FSS score(r=-0.526).All comparisons were Ptients with MCI and sleep disorders have lower near-infrared brain function than norm

Probing the color structure of the perfect QCD fluids via soft-hard-event-by-event azimuthal correlations

引用

Chinese Physics C 2018年第10期42卷 127-133页

作者： Shuzhe Shi Jinfeng liao Miklos Gyulassy Physics Department and Center for Exploration of Energy and Matter Indiana University Nuclear Science Division Lawrence Berkeley National Laboratory Pupin Lab MS-5202 Department of Physics Columbia University Institute of Particle Physics and Key Laboratory of Quark & Lepton Physics (MOE) Central China Normal University

We develop a comprehensive dynamical framework, CIBJEt, to calculate on an event-by-event basis the dependence of correlations between soft （Pt 〈2 GeV） and hard （Pt 〉 10 GeV） azimuthal flow angle harmonics on the color composition of near-perfect QCD fluids produced in high energy nuclear collisions at RHIC and LHC. CIBJEt combines consistently predictions of event-by-event VISHNU2＋I viscous hydrodynamic fluid fields with CUJEt3.1 predictions of event-by-event jet quenching. We find that recent correlation data favor a temperature dependent color composition including bleached chromo-electric q（t）＋g（t） components and an emergent chromo-magnetic degrees of freedom re（t） consistent with non-perturbative lattice QCD information in the confinement/deconfinement temperature range.

Correlation between intrinsic dipole moment and pyroelectric coefficient of Fe-Mg tourmaline

引用

International Journal of Minerals,Metallurgy and Materials 2014年第2期21卷 105-112页

作者： Chang-chun Zhao Li-bing liao Jie Xing School of Science China University of Geosciences School of Materials Science and technology China University of Geosciences

Single-crystal X-ray diffraction structural data of four Fe-Mg tourmalines with different Fe contents from Xinjiang, Sichuan, and Yunnan Provinces, China, were collected at room temperature and-100oC. the intrinsic dipole moments of polyhedra and the total intrinsic dipole moment of the unit cell were calculated. By comparing the intrinsic electric dipole moments of the X, Y, Z, t, and B site polyhedra, it is found that the t site polyhedron makes the greatest contribution to the total intrinsic dipole moment. the pyroelectric coefficients of four Fe-Mg tourmalines were experimentally determined, and the influence of intrinsic dipole moments on their pyroelectric properties was inves-tigated. the experimental results show that, compared with the case at room temperature, the intrinsic dipole moments change with the total Fe content at-100oC in a completely different way. With the decrease of temperature, the total intrinsic dipole moments of tourmaline de-crease. Over the same temperature interval, the pyroelectric coefficients increase with the increase in intrinsic dipole moment.

Effects of indium on precipitation in Al-3.3Cu-0.8Li alloy

Acta Metallurgica Sinica(English Letters) 2010年第4期23卷 285-292页

作者： Zhengrong PAN Ziqiao ZHENG Zhongquan liao Shichen LI School of Materials Science and Engineering Central South University Changsha 410083 China

the effects of 0.5 wt pct In on Al-3.3Cu-0.8Li alloy were studied. Instead of t1 （Al2CuLi） phase, there was an unknown cubic phase acting as the dominant precipitates in the In-added alloy in t6 temper, which disappeared in t8 temper. the orientation relationship between this phase and matrix was given by SAEDs：（001）p//（001）α, [010]p//[010]α. Both measuring directly from HREM images or calculating from it＇s FFts gave an close lattice parameter about 0.83 nm. 3DAP composition analysis revealed the presence of Al, Cu and Li in the atomic percentages： 60%Al, 30%Cu and 10%Li. thus, this cubic phase is considered to be Li-rich γ1 （Al4Cu9） phase or a new phase designated as X （Al5Cu6Li2）. Different from the traditional report providing heterogeneous nucleation sites for the precipitates, In was detected neither around nor in the cubic phase by EDX and 3DAP.

Data modelling for crude oil migration studies using ranking method: a rapid geo-tracer technique for geochemists

Acta Geochimica 2018年第6期37卷 901-910页

the direction of oil charges within a field in the Niger Delta, Nigeria was determined by the sum of differences ranking method of carbazole concentrations after ascertaining other possible geological constraints on their compositional variations. the principle is that the smaller the sum, the closer the well to the source kitchen. the approach makes use of carbazoles' interaction with the matrix, which leads to a reduction in their concentration with increasing distance from the source kitchen, allowing prediction of the charging direction. A wide range of compositional variations was observed for C1(806.72–2152.90 lg/g) and C2(767–2469.72 lg/g) carbazoles within the field. Based on these results, we inferred a filling pathway orientation from west to east. this suggests that the source kitchen—the most promising region for oil exploration—is located in the western part of the oil field.

We study two aspects of higher dimensional operators in standard model effective field *** first introduce a perturbative power counting rule for the entries in the anomalous dimension matrix of operators with equal mass *** power counting is determined by the number of loops and the difference of the indices of the two operators involved,which in turn is defined by assuming that all terms in the standard model Lagrangian have an equal perturbative *** we show that the operators with the lowest index are unique at each mass dimension d,i.e.,(H^(†)H)^(d/2)for even d≥4,and(L^(t)εH)C(L^(t)εH)^(t)(H^(†)H)^((d-5)/2)for odd d≥*** H,L are the Higgs and lepton doublet,andε,C the antisymmetric matrix of rank two and the charge conjugation matrix,*** renormalization group running of these operators can be studied separately from other operators of equal mass dimension at the leading order in power *** compute their anomalous dimensions at one loop for general d and find that they are enhanced quadratically in d due to *** also make connections with classification of operators in terms of their holomorphic and anti-holomorphic weights.
