Variation of dielectronic satellite intensity factors with n for dielectronic recombination processes in selected lithium-like ions

Satellite intensity factors F_2~*(s→f) have been calculated for the 1s~22s+εl→(1s~23l'nl'')~*→1s~22sml'''+hv dielectronic recombination processes of lithium-like V, Cu, Se, Ag and Ba ions. The relevant atomic parameters have been calculated explicitly for all intermediate resonance states |s> ≡ 1s~23l'nl''SLJ> with n=3-9 in the intermediate coupling scheme. The 1/n~3 scaling, which has often been used in extrapolating F~*(s→f) for n ≥ 4, is tested against these values of F_2~*(s→f).
Current Self-Oscillations in Negative Effective Mass Terahertz Oscillators

We theoretically study current self-oscillations and spatiotemporal current patterns in quantum-well negative effective mass (NEM) p~+pp~+ diodes by considering scattering contributions from impurity, acoustic phonons and optic phonons. It is indicated that both the applied bias and the doping concentration strongly influence the patterns and self-oscillating frequencies. The NEM p~+pp~+ diode presented here may be used as an electrically tunable terahertz source.
Universal Quantum Fluctuations and Crossover Phenomena in Tunnelling Through Small Coulomb Islands

Tunnelling through small Coulomb islands is studied in the intermediate coupling regime based on a generalized multi-level Anderson-Wolff model.It is shown that conductance and magnetization as a function of voltage exhibit a type of universal quantum fluctuation.We predict new crossover from the Coulomb blockade oscillations to the universal conductance fluctuations,and the Coulomb blockade oscillation assisted Kondo peaks.
Study of Static Adsorption Capacity of ACF for Xenon at 201 K

The static adsorption performances of a series of active carbon fiber (ACF) for xenon at 201 K were measured with a model ASAP2010M specific surface area and aperture distribution instrument by changing the working gas of instrument from Nj to Xenon. Compared with grain active carbon (GAC): (1) the adsorption performance of Viscose-based ACF(VACF) adsorbents is better than that of GACi (2) owing to the difference of aperture distribution, the adsorption performance of ACF with different radicales is different under the same experiment conditions though the specific surface area is similar) (3) there is no definite relationship between adsorption performance and specific surface areai (4) the VACF-A2 is the superior xenon adsorbent at the experimental temperature.
Application of two-color interphase fish using sex probe in allogeneic stem cell transplantation

To evaluate the significance of two-color interphase fluorescence in situ hybridization (FISH) using X and Y centromere probe in the engraftment estimation and minimal residual disease (MRD) monitoring after allogeneic stem cell transplantation (alloSCT). Methods: Samples from 12 cases patients in different periods after alloSCT were detected by interphase FISH. Results: All of the 12 patients were proved to obtain engraftment 22-35 days after alloSCT. While traditional karyotype showed as 100% XX or 100%XY invariably, FISH showed different percentages of donor original sex chromosome. Conclusion: Two-color interphase FISH is a more sensitive and simple test for engraftment evaluation and MRD monitoring post SCT, though, it can not entirely replace traditional karyotype analysis and gene detection by RT-PCR.
Invariant theory and exact solutions of the time-dependent supersymmetric two-level multiphoton Jaynes-Cummings model

On the basis of the fact that the two-level multiphoton Jaynes-Cummings (TLMJC) model possesses a supersymmetric structure, an invariant is constructed in terms of the supersymmetric generators by working in the sub-Hilbert-space corresponding to a particular eigenvalue of the conserved supersymmetric generators (the time-independent invariant). In this paper, we investigate the invariant-related unitary transformation approach to exact solutions of the time-dependent TLMJC model.
The Influence of Temperature on Ethene Diffusion in H[Al]ZSM-5 Studied by Molecular Dynamics

Molecular dynamics(MD) simulation of ethene diffusion in the lattice of H[Al]ZSM-5 was performed at the temperature ranging from 300 K to 700 K. The calculated diffusion coefficients increase with the tempera-ture from 2.60 * 10~(-9) m~2/s m~2/s at 300 K to 12.78 * 10~(-9) m~2/s at 700 K. The Arrhcnius plot gives an activation energy of 6.31 kJ/mol. The anisotropy of the diffusion process was examined.
Detection of micrometastases of lung cancer by using lunx mRNA specific reverse transcription-polymerase chain reaction

To detect of lung cancer micrometastases in peripheral blood and regional lymphatic nodes by using lunx mRNA specific reverse transcription-polymerase chain reaction (RT-PCR). Methods: RT-PCR was used to detect lunx mRNA in peripheral blood of 26 patients with lung cancer. We also detected 44 regional lymphatic nodes obtained from 25 patients with lung cancer who underwent curative lobectomy. All the 44 regional lymphatic nodes were also examined by histopaihology. Micrometastatic tumor cells in the peripheral blood and regional lymphatic nodes were semiquantitatively determined with the ratio of lunx band intensity to the glyceraldehydes-3-phosphate dehydrogenase band intensity. Results: The positive detection rate of lunx mRNA in peripheral blood for non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) patients were 60% (12/20) and 67% (4/6) respectively. 16 (36.4%) of regional lymphatic nodes from 44 lung cancer patients were positive by RT-PCR while 6 (13.6%) were positive by histopathology (x2=6.06, P=0.014). However, no blood samples and lymphatic nodes from patients with benign pulmonary diseases or normal volunteers were positive for lunx mRNA. The positive detection rate of lunx mRNA in bone marrow of NSCLC amd SCLC patients were 65% (13/20) and 67% (4/6) respectively. Conclusion: RT-PCR amplification of lunx mRNA is an sensitive and specific means to detect early haematogenous and regional lymphatic nodes dissemination of cancer cells for patients with lung cancer.
A Kinetic Study of the Non-isothermal Crystallization of a Zr-Based Bulk Metallic Glass

The kinetics of the non-isothermal crystallization of Zr55Cu30Al10Ni5 bulk metallic glass was studied by differential scanning calorimetry in the mode of continuous heating. It is found that both glass transition and crystallization of the amorphous alloy behave in a marked kinetic nature. The activation energy E and frequency factor k0 for crystallization were determined by the Kissinger method, which yields E = 230 kJ/mol, and k_0 = 4.2×10~(12)/s. The value of k_0 is much smaller than that for conventional amorphous alloys, demonstrating that the atomic mobility in bulk metallic glasses is quite sluggish. The crystallization mechanism in the non-isothermal process was analysed in terms of the kinetic transformation equation for the solid-state phase transformation. This reveals that the crystallization kinetic function f(x) for Zr_(55)Cu_(30)Al_(10)Ni_5 can be described by the Johnson-Mehl-Avrami equation, i.e. f(x) = (1-x)[-ln (1-x)]~((n-1)/n), with n = 1.75. This indicates that the non-isothermal crystallization of Zr55Cu30Al10Ni5 bulk metallic glass is governed by diffusion-controlled one-dimensional growth. Finally, the different crystallization mechanisms in the isothermal and non-isothermal processes are discussed.
The Effective Degree of Freedom of Low Energy QCD

The adiabatic effective baryon-baryou interactions and dibaryon candidates are studied systematically with three constituent quark models based on different effective degrees of freedom:Glozman-Riska-Brown Goldstone boson exchange model based on constituent quark and Goldstone boson coupling;Fujiwara model based on constituent quark gluon coupling and Nijmegen one-boson exchange;QDCSM based on constituent quark and gluon coupling with quark delocalization and color screening.We find that the three models predicted the similar effective baryon-baryon interactions for roughly two thirds among the 64 states consisted of octet and decuplet baryons.The differences among three models and their separate characteristics are also studied.
Search for Exotic States in J/ψ→ρηπ

It is an ideal place to search for exotic states through J/ψ hadronic decays.In this paper,we discuss the way to use the partial wave analysis (PWA) based on covariant helicity amplitude analysis to study the invariant mass spectrum of  ηπ and to find the evidence of the existence of exotic states in this channel.The formula for PWA is also given.It is the theoretical foundation of experimental physics analysis on exotic states searching in J/ψ hadronic decays.The theoretical formula can also be used in physics analysis of J/ψ decays into ωππ，φππ，ωKK，φKK and K^* (892)Kπ.
A Silicon-Based Ferroelectric Capacitor for Memory Devices

We study a silicon-based PbTiO_3/Pb(Zr0.53Ti0.47)O3/PbTiO_3 capacitor, prepared by an improved sol-gel method. The ferroelectric capacitor has a high remanent polarization of 15 μC/cm~2 at a coercive field of about 30 kV/cm, an ultra-low leakage current density of 0.1 nA/cm~2, and almost fatigue free properties. It can be used as a promising candidate for ferroelectric memory devices.
Robust Feedback Controller for Exponential Stability of Nonlinear Systems with Mismatched Uncertainties

The robust stabilization of nonlinear systems with mismatched uncertainties is investigated. Based on the stability of ihe nominal system, a new approach to synthesizing a class of continuous state feedback controllers for uncertain nonlinear dynamical systems is proposed. By such feedback controllers, the exponential stability of uncertain nonlinear dynamical systems can be guaranteed. The approach can give a clear insight to system analysis. An illustrative example is given to demonstrate the utilization of the approach developed. Simulation results show that the method presented is practical and effective.
Studies on Interaction Between Gallocyanine and DNA

The interaction of Gallocyanine(Gal) with DNA was studied by using UV spectra and circular clichroism (CD) spectrum methods. Gal and DNA strongly interacted on each other in acid solutions. The intrinsic binding constant (K) and the binding numbers (C_(dna)/C_(Gal)) of Gal and DNA are 2.25 * 10~4 mol~4 and 2.5, re-spectively. The influence of pH on the interaction of Gal and DNA was also studied.
SO(d,d;Z) Transformation Property for Gauge Fluxes and Ramond-Ramond Fields in Noncommutative Geometry

In this paper we study the spinor constructions of gauge fluxes and Ramond-Ramond fields on noncommutative tori T~d up to d = 6. In which the spinor and conjugate spinor are distinguished and dual bases are also introduced. So that we can express the Chern-Simons Lagrangian in toroidal compactification as a product of spinors.
Lattice Strain Induced by Ion Implantation in AlGaAs/AlGaInAs Quantum Well Samples

Si~+ ions of 350 keV have been implanted into AlGaAs/AlGaInAs quantum well samples in the dose range from 5 * 10~(13)cm~(-2) to 5 * 10~(14)cm~(-2). The Raman spectra and high resolution x-ray diffraction (HRXRD) were measured from these implanted samples as well as the non-implanted sample. In the implanted layers the average strain which was evaluated by HRXRD increases with the implantation doses and varies from 0.0011 to 0.0029. The quantum well interface intermixing effect and compositional modification are also observed from HRXRD. At the higher doses, an abnormal annealing procedure takes place and it partly removes damage, but the strain remains almost unchanged in the epilayers.
Two-Photon-Absorption Induced Superradiance of a New Organic Dye PSPS

The linear and nonlinear optical properties of a new two-photon absorption (TPA) dye, trans-4-(4'-pyrrolidinyl styryl)-N-methyl pyridinium methyl sulfate (abbreviated as PSPS) is reported. Intense red superradiance with a peak located at 625nm can be observed from PSPS solution in benzyl alcohol when pumped by a focused picosecond laser beam operated at 1064nm. The lifetimes of one-photon absorption (OPA) and TPA fluorescence were measured to be 370 and 384ps, respectively. The pulse widths of OPA and TPA superradiance were 60 and 58 ps, respectively. The highest net upconversion efficiency from the absorbed pump laser to the upconverted superradiance is 8.3% at the pump energy of 0.6 mJ.
High-Quality ZrO_2 Thin Films Deposited on Silicon by High Vacuum Electron Beam Evaporation

Zirconium oxide films were deposited on p-type Si(100) substrates using high vacuum electron beam evaporation (HVEBE) at room temperature. X-ray photoelectric spectroscopy shows that the dominant chemical state of zirconia thin films is in the fully oxidized state of Zr~(4+), no matter whether annealed in oxygen. The structural information from x-ray diffraction shows that zirconia thin films deposited at room temperature by HVEBE were completely amorphous before and after the annealing. The spreading resistance profile indicates that ZrO_2 thin films have excellent insulation property (with a resistance of more than 108 ) and the thickness is 800 ?. After thermal treatment at 600°C in O2 ambient, the root-mean-square roughness changed from 8.09 ? of the as-deposited film to 13.8 ? across an area of 1×1 μm~2.
Modulation Spectroscopy of GaAs Covered by InAs Quantum Dots

Contactless electroreflectance has been employed at room temperature to study the Fermi level pinning at undoped-n+ GaAs surfaces covered by 1.6 and 1.8 monolayer (ML) InAs quantum dots (QDs). It is shown that the 1.8 ML InAs QD moves the Fermi level at GaAs surface to the valence band maximum by about 70 meV compared to bare GaAs, whereas 1.6 ML InAs on GaAs does not modify the Fermi level. It is confirmed that the modification of the 1.8 ML InAs deposition on the Fermi level at GaAs surface is due to the QDs, which are surrounded by some oxidized InAs facets, rather than the wetting layer.
Spectral Representation Theory for Dielectric Behavior of Nonspherical Cell Suspensions

Recent experiments wvealed that the dielectric dispersion spectrum of fission yeast cells in a suspension was mainly composed of two sub-dispsrslons, The low-frequency sub-dispersion depended on the call length, while the high-frequency one was independent of it, The cell shape effect was simulated by an ellipsoidal cell model hut the comparison between theory and experiment was far from being satisfactory, Prompted by the discrepancy, we proposed the use of spectral representation to analyze more realistic cell models, We adopted a shell-spheroidal model to analyze the effects of the csll membrane. It is found that the dielectric property of the cell membrane 1ms only a minor effect on the dispersion magnitude ratio and the characteristic frequency ratio, We further included the effect of rotation ofdipole induced by an external electric Held, and solved the dipo/e-rotation spheroidal model in the spectral representation. Good agreement between theory and experiment has been obtained.
Preparation and Annealing-Induced Structural Transition of Self-Organized Nanostripes on the Electropolished Aluminium Surface

Self-organized nanostripe patterns with a wavelength of 100 nm and an amplitude of 4-5 nm were formed on the surface of high-purity aluminium by electropolishing. The thermal stability of the nanostripe patterns was investigated experimentally by using a needle-sensor atomic force microscope in an ultra-high vacuum after annealing the sample in a high vacuum. We found that the originally highly ordered nanostripe structures transformed into many domains separated by various boundaries, and different nanostripe patterns formed, the belt-like boundaries especially formed ``cross'' patterns on the surface. We also found that the vacuum annealing had the tendency to efface the nanostripe structures.
Influence of Ba~(2+) and Pb~(2+) Ions on the Raman Dominating Active Vibronic Mode in Strontium Nitrate Crystals

The compositions of Sr(NO_3)_2 crystals grown from an aqueous solution doped with Ba~(2+) and Pb~(2+) were characterized by the electron probe microanalysis technique. It was found that Ba~(2+) is enriched in {100} sectors and Pb~(2+) in {111} sectors. The Raman spectra of different parts of these crystals at room temperature in the ranges of 1038-1070 cm~(-1) and 650-1150 cm~(-1) were investigated. The results indicated that barium and lead shift the Raman dominating peaks to the lower frequency and broaden the full width at half maximum. Furthermore, barium probably degrades the properties of the Sr(NO_3)_2 Raman shifter while lead is anticipated to improve it.
Scaling Law of Exponents in Cosmological Clustering

The density of N-clusters (the clusters which contain N galaxies) in the Universe is shown from observations to scale with N as n_N ∝ N~(-τ) with τ = 3/γ + 1 and the correlation exponent γ ≈ 1.8. Correspondingly, a scaling relation τ = 29 - 9γ/12 - 4γ between the two exponents, which agrees with the observations, is found analytically in our naive clustering model.
Effects of Charge Transfer Agents on the Holographic Parameters of a Photopolymer

The principle of charge transfer agents was investigated experimentally. There is a compensation effect between triethanolamine (TEA) and diphenyliodonium hexafluorophosphate (DPI) in the polymerization process of a photopolymer. The experimental results illustrate that TEA has a stronger effect in the initial stage of exposure, and DPI has a stronger effect during the propagation stage of the polymerization process. We explain the main contributions of DPI in the superadditive photopolymer kinetics that results in an obvious increase of sensitivity.
General Solution and Fractal Localized Structures for the (2+1)-Dimensional Generalized Ablowitz-Kaup-Newell-Segur System

Using the standard truncated Painlevé expansions, we derive a quite general solution of the (2+1)-dimensional generalized Ablowitz-Kaup-Newell-Segur system. Except for the usual localized solutions, such as dromions, lumps, ring soliton solutions, etc, some special localized excitations with fractal behaviour, i.e. the fractal dromion and fractal lump excitations, are obtained by some types of lower-dimensional fractal patterns.
A New Method for the Analysis of Relative Permeability in Porous Media

By combining three-dimensional digital microtomography techniques with the lattice Boltzmann method, a new methodology is used to analyse the relative permeability of multiphase flow in porous media. The results indicate that the two coupling coefficients K12 and K21 have the same magnitude, therefore the Onsager reciprocity still holds. The results also agree well with the results of pipe flow numerical experiments.
Detecting Toppion via a Flavor-Changing Single Top quark Production Process

In the framework of topcolor-assisted technicolor (TC2) theory, we study a flavor changing single top quark production process pp-bar(pp)→Π_t~0 →tc-bar(t-bar c) at upgraded Tevatron and LHC. The results show that with the flavor changing coupling of neutral toppion to top and charm quark, toppion provides a large tc-cha.nnel resonance effect. The signal of single top production could be detected at LHC, Otherwise, the narrow peak in the invariant mass distribution could bo clearly detected both at upgraded Tevatron and LHC. Therefore, such single top production process provides a unique way to test TC2 model via the detection of tc-channel neutral toppion contribution.
A Measurement Method of Time Jitter of a Laser Pulse with Respect to the Radio-Frequency Wave Phase in a Photocathode Radio-Frequency Gun

In a photo-cathode radio-frequency (rf) gun, the micro-bunched charge output from the gun is dependent linearly on the laser injection phase, due to the Scottay effect in the process of photoemission and the procedure of the electron longitudinal acceleration. Based on this principle, a new method is proposed, which should be utilized to measure the time jitter between the driving laser pulse and the rf phase with a very high resolution of a few tens of femtoseconds.
Dynamic Stabilization by Modulated Toroidal Current on the HT-7 Superconducting Tokamak

The technique of toroidal current modulation has been successfully used in suppressing magnetohydrodynamic (MHD) perturbations effectively on the HT-7 superconducting tokamak. When the ratio of amplitude of plasma modulated current ΔI_p versus the equilibrium plasma current I_(p0) is about 12-30%, the resonance surface is moved outside the island width, and the suppression of MHD perturbations is observed. The disruption induced by tearing mode instability is delayed or avoided. Different formats of frequency modulated are compared
The Development of Gel Media and Columns for Large-Scale Chromatography of Proteins, a Historical Review

The first dedicated protein chromatography media were introduced during the 1950s and 1960s, There was an early awareness of the possibility of using these for production applications within the biopharmaceutical industry. However, the crucial limitation was the fact that those media that were most compatible with proteins lent themselves less favourably to scaling-up. The problems were primarily physical. Thus die fibrous cellulose media showed bed cracking tendencies and the bead shaped polyacrylamide, dextran, and agarose gel media, then available, were too soft to stand the hydrodynamic forces acting in large columns, leading to bed compaction and increased pressure drop. At the time, the best solution to the latter problem, after a number of intermediary solutions were tried, was the introduction of the stacked column concept in which several short column segments were connected by small bore tubing, thus reducing the force acting on the particles in each bed com-partment. However, the ultimate remedy, the introduction of chromatographic matrices that combine the desired features of adequate rigidity, macroporosity, biocompatibility, chemical stability (for CIP and SIP) and derivatizability, did not occur until the middle of the 1980s when ade-quately cross-linked agarose gel media such as Sepharose Fast Flow were made available. The paper also recognizes the many attempts made during the past 50 years to develop continous chromatography columns. Most of the designs are based on an annular bed or on an array of an-nularly arranged parallel columns continuously fed with samples in a cyclic manner. The introduction of media and columns for expanded bed adsorption followed a demand for fewer purification steps and shorter process times. In recent years, columns have been introduced that allow packing and repacking without needing to open the column. The review provides an historical account of the developments that have led to the present state-of-the-art both regarding large diameter columns and gel media intended for industrial applications of protein, chromatography and also discusses the current trends that point to possible future applications.
Nuclear Shadowing Effect on the K Factor in Au-Au Collisions

We investigate the nuclear shadowing effect on the K factor in the Drell-Yan process by introducing a shadowing factor into the corresponding quantum chromodynamical α_s order corrections. K factors for Au-Au collisions are calculated at the centre-of-mass system energies s~(1/2) = 60, 130 and 200 GeV while the nuclear shadowing factor is taken into account. The numerical results indicate that the nuclear shadowing factor obviously raises the K value in the small x region, and for the same nucleon the K value becomes smaller as the energy increases. The nuclear shadowing effect could be one reason for creating the non-constancy of the K factor.
