·AIM: to evaluate the quality of vision in respect to high order aberrations and straylight perception after implantation of an aspheric, aberration correcting,monofocal intraocular lens(IOL).·MEtHODs: twenty-one patients(34 eyes) aged 50 to83 y underwent cataract surgery with implantation of an aspheric, aberration correcting IOL(tecnis ZCB00,Abbott Medical Optics). three months after surgery they were examined for uncorrected(uDVA) and corrected distance visual acuity(CDVA), contrast sensitivity(Cs)under photopic and mesopic conditions with and without glare source, ocular high order aberrations(HOA, Zywave II) and retinal straylight(C-Quant).· REsuLts: Postoperatively, patients achieved a postoperative CDVA of 0.0 log MAR or better in 97.1% of eyes. Mean values of high order abberations were +0.02±0.27(primary coma components) and-0.04 ±0.16(spherical aberration term). straylight values of the C-Quant were 1.35±0.44 log which is within normal range of age matched phakic patients. the Cs measurements under mesopic and photopic conditions in combination with and without glare did not show any statistical significance in the patient group observed(P ≥0.28).· CONCLusION: the implantation of an aspherical aberration correcting monofocal IOL after cataractsurgery resulted in very low residual higher order aberration(HOA) and normal straylight.

Applied Mathematics and Mechanics(English Edition) 2012年第10期33卷 1313-1328页

作者： O.u.MEHMOOD N.MustAPHA s.sHAFIE Department of Mathematics Faculty of ScienceUniversiti Teknologi Malaysia81310 UTM JohorJohor BharuMalaysia

In this paper, the effects of slip and heat transfer are studied on the peristaltic transport of a magnetohydrodynamic （MHD） fourth grade fluid. the governing equations are modeled and solved under the long wavelength approximation by using a regular perturbation method. Explicit expressions of solutions for the stream function, the velocity, the pressure gradient, the temperature, and the heat transfer coefficient are presented. Pumping and trapping phenomena are analyzed for increasing the slip parameter. Further, the temperature profiles and the heat transfer coefficient are observed for various increasing parameters. It is found that these parameters considerably affect the considered flow characteristics. Comparisons with published results for the no-slip case are found in close agreement.

作者： G.BARtH s.VON tuCHER u.sCHMIDHALtER Chair of Plant Nutrition Technical University MunichD-85350 Freising-Weihenstephan(Germany)

the efficacy of nitrification inhibitors depends on soil properties and environmental conditions. the nitrification inhibitor 3.4-dimethylpyrazole phosphate （DMPP） was investigated in a sandy loam and a loamy soil to study its effectiveness as influenced by inhibitor concentration, application form, and soil matric potential. DMPP was applied with concentrations up to 34.6 mg DMPP kg^-1 soil as solution or as ammonium-sulfate/ammonium-nitrate granules formulated with DMPP. DMPP inhibited the oxidation of ammonium in both soils, but this effect was more pronounced in the sandy loam than in the loamy soil. When applied as solution, increasing DMPP concentrations up to 7 mg DMPP kg^-1 soil had no influence on the inhibition. the effectiveness of DMPP formulated as fertilizer granules was superior to the liquid application of DMPP and NH4^＋, particularly in the loamy soil. Without DMPP, a decline in soil matric potential down to -600 kPa decreased nitrification in both soils, but this effect was more pronounced in the sandy loam than in the loamy soil. DMPP was most effective in the sandy loam particularly under conditions of higher soil moisture, i.e., under conditions favorable for nitrate leaching.

Background： Adaptive response includes a variety of physiological modifications to face changes in external or internal conditions and adapt to a new situation. the acute phase proteins（APPs） are reactants synthesized against environmental stimuli like stress, infection, ***： to delineate the differences in molecular constituents of adaptive response to the environment we performed the whole-blood transcriptome analysis in Italian Holstein（IH） and Italian simmental（Is） breeds. For this, 663 IH and Is cows from six commercial farms were clustered according to the blood level of APPs. ten extreme individuals（five APP＋ and APP-variants） from each farm were selected for the RNA-seq using the Illumina sequencing technology. Differentially expressed（DE） genes were analyzed using dynamic impact approach（DIA）and DAVID annotation clustering. Milk production data were statistically elaborated to assess the association of APP＋ and APP-gene expression patterns with variations in milk ***： the overall de novo assembly of cDNA sequence data generated 13,665 genes expressed in bovine blood cells. Comparative genomic analysis revealed 1,152 DE genes in the comparison of all APP＋ vs. all APP-variants; 531 and 217 DE genes specific for IH and Is comparison respectively. In all comparisons overexpressed genes were more represented than underexpressed ones. DAVID analysis revealed 369 DE genes across breeds, 173 and 73 DE genes in IH and Is comparison respectively. Among the most impacted pathways for both breeds were vitamin B6 metabolism, folate biosynthesis, nitrogen metabolism and linoleic acid ***： Both DIA and DAVID approaches produced a high number of significantly impacted genes and pathways with a narrow connection to adaptive response in cows with high level of blood APPs. A similar variation in gene expression and impacted pathways between APP＋ and APP-variants was found between two studied breeds. such similarity was also c

Characterization of isolated homogeneous hypersurface singularities in C^4

science China Mathematics 2006年第11期49卷 1576-1592页

作者： YAu stephen s t Department of Mathematics statistics and Computer science University of Illinois at ChicagoChicagoIL 60607-7045USA

Let V be a hypersurface with an isolated singularity at the origin in Cn+1. It is a natural question to ask when V is defined by weighted homogeneous polynomial or homogeneous polynomial up to biholomorphic change of coordinates. In 1971, a beautiful theorem of saito gives a necessary and sufficient condition for V to be defined by a weighted homogeneous polynomial. For a two-dimensional isolated hypersurface singularity V, Xu and Yau found a coordinate free characterization for V to be defined by a homogeneous polynomial. Recently Lin and Yau gave necessary and sufficient conditions for a 3-dimensional isolated hypersurface singularity with geometric genus bigger than zero to be defined by a homogeneous polynomial. the purpose of this paper is to prove that Lin-Yau's theorem remains true for singularities with geometric genus equal to zero.

Activated carbon （AC） derived from waste coconut buttons （CB） was investigated as a suitable adsorbent for the removal of heavy metal ions such as Pb（II）, Hg（II） and Cu（II） from industrial effluents through batch adsorption process. the AC was characterized by elemental analysis, fourier transform infrared spectroscopy, X-ray diflraction, scanning electron microscopy, thermal gravimetric and diflerential thermal analysis, surface area analyzer and potentiometric titrations. the eflects of initial metal concentration, contact time, pH and adsorbent dose on the adsorption of metal ions were studied. the adsorbent revealed a good adsorption potential for Pb（II） and Cu（II） at pH 6.0 and for Hg（II） at pH 7.0. the experimental kinetic data were a better fit with pseudo second-order equation rather than pseudo first-order equation. the Freundlich isotherm model was found to be more suitable to represent the experimental equilibrium isotherm results for the three metals than the Langmuir model. the adsorption capacities of the AC decreased in the order： Pb（II） Hg（II） Cu（II）.

Impacts of soil Additives on Crop Yield and C-sequestration in Post Mine substrates of Lusatia,Germany

Pedosphere 2012年第3期22卷 343-350页

作者： A.RODIONOV s.NII-ANNANG O.BENs M.tRIMBORN s.sCHILLEM B.u.sCHNEIDER t.RAAB R.F.HttL Institute of Crop science and Resource Conservation University of BonnBonn 53115 (Germany) Faculty of Environmental science and Process Engineering Brandenburg University of TechnologyCottbus 03046 (Ger-many) German Research Centre for Geosciences GFZ Potsdam 14473 (Germany)

Opencast lignite mining in the Lusatia region of Germany has resulted in large scale landscape disturbances, which require suitable recultivation techniques in order to promote plant growth and establishment in the remaining nutrient-poor substrates with low water-holding capacity. thus, the effects of two commercial soil additives （CsA）, a hydrophilic polymer mixed with volcanic rock flour and bentonite （a-CsA）, and digester solids from biogas plants enriched with humic acids and bentonite （b-CsA）, on soil organic carbon （sOC） storage, plant yields and root biomass were assessed after cultivating perennial crops （Dactylis 9lornerata L.） in monoculture and Helianthus annuus L.-Brassica napus L. in crop rotation systems. the CsA were incorporated into the top 20 cm soil depth using a rotary spader. the results indicated that a-CsA led to a significant increase in plant yield during the first year, and improved root biomass in the following year. As a result, sOC stocks increased, especially in the 0 10 cm soil layer. No significant sequestration of additional sOC was observed on b-CsA-amended plots at the end of both years. Bulk density values decreased in all treatments under the monoculture system. It can be concluded that application of a-CsA enhanced soil water availability for plant uptake and consequently promoted plant growth and organic carbon sequestration. the relative enrichment of organic matter without effects on water-holding capacities of b-CsA treatments suggested that it was not suitable for rapid land reclamation.

uncertainty, certainty, and relativity(Invited Paper)

Chinese Optics Letters 2016年第1期14卷 2-6页

作者： Francis t.s.Yu Department of Electrical Engineering Penn State University

One of the most fascinating principles in quantum mechanics must be Heisenberg＇s uncertainty principle, which can be briefly stated as follows： every physicM observation cannot be precisely determined without some degree of error or uncertainty. And it is by no means can one use the principle within the limit of certainty region, as will be shown in this Letter. two of the most important pillars in modern physics must be Einstein＇s relativity theory and schrsdinger＇s contribution to quantum mechanics. Yet, there is a profound connection between these discoveries by means of the uncertainty relationship, in which we shown that the observation of a high-speed object is conceivable if the speed of the observer keeps up with object＇s speed.

A mathematical model for avian influenza with optimal control strategies is presented as a system of discrete time delay differential equations （DDEs） and its important math-ematical features are analyzed. In alignment to manage this, we develop an optimally controlled pandemic model of avian influenza and insert a time delay with exponential factor. then we apply two controlled functions in the form of biosecurity of poultry and the education campaign against avian influenza to control the disperse of the dis- ease. Our optimal control strategies will minimize the number of contaminated humans and contaminated birds. We also derive the basic reproduction number to examine the dynamical behavior of the model and demonstrate the existence of the controlled system. For the justification of Our work, we present numerical simulations.
