Two-probe theory of scanning tunneling microscopy of single molecules: Zn(II)-etioporphyrin on alumina

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We explore theoretically the scanning tunneling microscopy of single molecules on substrates using a framework of two local probes. This framework is appropriate for studying electron flow in tip/molecule/substrate systems where a thin insulating layer between the molecule and a conducting substrate transmits electrons non-uniformly and thus confines electron transmission between the molecule and substrate laterally to a nanoscale region significantly smaller in size than the molecule. The tip-molecule coupling and molecule-substrate coupling are treated on the same footing, as local probes to the molecule, with electron flow modelled using the Lippmann-Schwinger Green function scattering technique. STM images are simulated for various positions of the stationary (substrate) probe below a Zn(II)-etioporphyrin I molecule. We find that these images have a strong dependence on the substrate probe position, indicating that electron flow can depend strongly on both tip position and the location of the dominant molecule-substrate coupling. Differences in the STM images are explained in terms of the molecular orbitals that mediate electron flow in each case. Recent experimental results, showing STM topographs of Zn(II)-etioporphyrin I on alumina/NiAl(110) to be strongly dependent on which individual molecule on the substrate is being probed, are explained using this model. A further experimental test of the model is also proposed.

Volume fluctuations and geometrical constraints in granular packs

Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: Structural organization and correlations are studied in very large packings of equally sized acrylic spheres, reconstructed in three-dimensions by means of X-ray computed tomography. A novel technique, devised to analyze correlations among more than two spheres, shows that the structural organization can be conveniently studied in terms of a space-filling packing of irregular tetrahedra. The study of the volume distribution of such tetrahedra reveals an exponential decay in the region of large volumes; a behavior that is in very good quantitative agreement with theoretical prediction. I argue that the system's structure can be described as constituted of two phases: 1) an `unconstrained' phase which freely shares the volume; 2) a `constrained' phase which assumes configurations accordingly with the geometrical constraints imposed by the condition of non-overlapping between spheres and mechanical stability. The granular system exploits heterogeneity maximizing freedom and entropy while constraining mechanical stability.

description: Pseudoaneurysm of the uterine artery is a rare complication of cesarean section. Delayed diagnosis and management may result in rapid and catastrophic postpartum hemorrhage and may necessitate hysterectomy or can even be fatal. A 28-year-old woman (gravida I, para I) presented with delayed postpartum hemorrhage 10 days after emergency cesarean section. Using transabdominal and transvaginal Color Doppler sonography, we detected a pseudoaneurysm in the posterior uterine wall, which was successfully treated with selective embolization distal and proximal to the lesion with platinum coils. In patients with delayed postpartum hemorrhage-especially after cesarean section-the rare possibility of uterine artery pseudoaneurysm must be kept in mind.

A novel method for metal recovery from zinc fuming slags
Creators: name: He, Fengxiang
Publisher: name: University of British Columbia
Year: 2009

description: In typical zinc & lead production operations, lead blast furnace slags and zinc leaching residues are usually fumed to recover zinc metal. Regardless of the fuming methods employed, the tail slag from zinc fuming furnaces still contains about 3 per cent or more zinc and some trace amounts of elements such as lead, indium and germanium. Although by traditional measures the contents of Zn, Pb, and the rarer elements In and Ge are very low, in absolute terms there is still the potential to extract considerable value from these remaining metals. As well, the elimination of these heavy metals from the slag would go even further in ensuing that the slags can be used as cement additives, landfill, roadbed material, etc. without environmental ramifications. A new electrochemical process, similar to the Hall-Heroult process in aluminum production, has been proposed for the recovery of metal values from this slag. Based on thermodynamic analysis and F*A*C*T calculations, copper melt was chosen as the cathode because it significantly decreases the activity of zinc while increasing the activity of iron. The results of synthetic slags (24.4 pct-Fe 39 pct-Si02 17 pct-CaO 6 pct-Al₂0₃ 2 pct-Zn) at 1250 °C revealed that 1) even without passing a direct current, a certain amount of zinc was diffused into the copper melt by the predicted thermodynamic driving force; 2) zinc was continuously deposited into the copper melt by electrochemical reaction when the voltage difference between the electrodes was 4 volts or greater. The effects of temperature and basicity on the process have also been studied. By the results of Fe ³⁺/Fe ²⁺ analysis and SEM examinations, possible reaction mechanism have also been suggested. The as-received Cominco tail slags were also examined by electrolysis.

description: We discuss the effects of a strong magnetic field in Quantum Wires. We show how the presence of a magnetic field modifies the role played by % which %coefficients corresponding to electron electron interaction % and the Fermi velocity producing a strong reduction of the backward scattering corresponding to the Coulomb repulsion. We discuss the consequences of this and other effects of magnetic field on the Tomonaga-Luttinger liquids and especially on their power-law behaviour in all correlation functions. The focal point is the rescaling of all the repulsive terms of the interaction between electrons with opposite momenta, due to the edge localization of the electrons and to the reduction of the length scale. Because of the same two reasons there are some interesting effects of the magnetic field concerning the backward scattering due to the presence of one impurity and the corresponding conductance. As an effect of the magnetic field we find also a spin polarization induced by a combination of electrostatic forces and the Pauli principle, quite similar to the one observed in large Quntum Dots.

description: This study examines the nature of Supply Chain Management (SCM) in the Canadian barley industry, economic theories related to SCM, identifies SCM drivers and reviews the Canadian barley marketing system. Two surveys were conducted; one on the feed barley segment of the market; another on the malt barley segment of the market. These surveys provide an outline of the attributes sought by buyers of feed barley in Alberta and by buyers of malt barley in Canada and the United States. A further goal of these surveys was to assess the extent of motivations for SCM in the barley supply chain. Study methods include scaling, factor analysis and stated preference techniques to analyze purchasers' preferences for specific product attributes, business relationships and product source. The major attributes of feed barley sought by Alberta feed manufacturers appear to be physical characteristics such as moisture level, absence of foreign material, high bushel weight and uniform appearance of kernels. Features identified as of moderate importance included levels of certain key amino acids, starch level in the barley sample, as well as such seller characteristics as whether the seller was personally known to the buyer, and willingness of the seller to enter into a long-term supply contract. At the level of the Alberta feed mill industry, results therefore indicate that physical, readily identifiable attributes dominate in the selection of feed barley. As a result, the study identified that SCM is not yet a part of the awareness of barley buyers at feed mills. Among buyers of malt barley, physical or easily assessed attributes such as size of kernel, germination percentage, variety and location where produced ranked highly in a factor analysis as important to malt barley buyers. While results from the sample of Canadian and US buyers did not indicate strong potential for SCM in the malt barley sector, the study found there to be differences in attributes desired by US versus Canadian malt purchasers. Main differences were the concern of US buyers with the region where the barley was grown, and the apparently much higher willingness of US buyers to obtain their malt barley from more than one source. These differences may suggest a potential for SCM in malt barley focused on procuring supplies from regions identified as preferred locations for barley used in malt production.

description: The prevalence and mortality rates of severe infections are high in intensive care units (ICUs). At the same time, the high pharmacokinetic variability observed in ICU patients increases the risk of inadequate antibiotic drug exposure. Therefore, dosing tailored to specific patient characteristics has a high potential to improve outcomes in this vulnerable patient population. This study aimed to develop a tabular dosing decision tool for initial therapy of meropenem integrating hospital-specific, thus far unexploited pathogen susceptibility information. An appropriate meropenem pharmacokinetic model was selected from the literature and evaluated using clinical data. Probability of target attainment (PTA) analysis was conducted for clinically interesting dosing regimens. To inform dosing prior to pathogen identification, the local pathogen-independent mean fraction of response (LPIFR) was calculated based on the observed minimum inhibitory concentrations distribution in the hospital. A simple, tabular, model-informed dosing decision tool was developed for initial meropenem therapy. Dosing recommendations achieving PTA > 90% or LPIFR > 90% for patients with different creatinine clearances were integrated. Based on the experiences during the development process, a generalised workflow for the development of tabular dosing decision tools was derived. The proposed workflow can support the development of model-informed dosing tools for initial therapy of various drugs and hospital-specific conditions.

description: The magnetic field in our Galaxy is not well known and is difficult to measure. A spiral regular field in the disk between the Galactic arms is favored by observations, however it is still controversial if the field reverses from arm to arm. The parity of the field across the Galactic plane is also not well established. In this letter we demonstrate that cosmic ray protons in the energy range 10^18 to 10^19 eV, if accelerated near the center of the Galaxy, can probe the large scale structure of the Galactic Magnetic Field. In particular if the field is of even parity, and the spiral field reverses direction from arm to arm, i.e. if it is bi-symmetric (BSS), ultra high energy protons will predominantly come from the Southern Galactic hemisphere, and predominantly from the Northern Galactic hemisphere if the field is of even parity and axi-symmetric (ASS). There is no sensitivity to the BSS or ASS configurations if the field is of odd parity.

description: The koala retrovirus (KoRV) is spreading in the koala population from the north to the south of Australia and is also in the process of endogenization into the koala genome. Virus infection is associated with tumorigenesis and immunodeficiency and is contributing to the decline of the animal population. Antibody production is an excellent marker of retrovirus infection; however, animals carrying endogenous KoRV are tolerant. Therefore, the therapeutic immunization of animals carrying endogenous KoRV seems to be ineffective. Using the recombinant transmembrane (TM) envelope protein of the KoRV, we immunized goats, rats and mice, obtaining in all cases neutralizing antibodies which recognize epitopes in the fusion peptide proximal region (FPPR), and in the membrane-proximal external region (MPER). Immunizing several animal species with the corresponding TM envelope protein of the closely related porcine endogenous retrovirus (PERV), as well as the feline leukemia virus (FeLV), we also induced neutralizing antibodies with similar epitopes. Immunizing with the TM envelope protein in addition to the surface envelope proteins of all three viruses resulted in higher titers of neutralizing antibodies. Immunizing KoRV-negative koalas with our vaccine (which is composed of both envelope proteins) may protect these animals from infection, and these may be the starting points of a virus-free population.

description: Investigations on ion channels in muscle tissues have mainly focused on physiological muscle function and related disorders, but emerging evidence supports a critical role of ion channels and transporters in developmental processes, such as controlling the myogenic commitment of stem cells. In this review, we provide an overview of ion channels and transporters that influence skeletal muscle myoblast differentiation, cardiac differentiation from pluripotent stem cells, as well as vascular smooth muscle cell differentiation. We highlight examples of model organisms or patients with mutations in ion channels. Furthermore, a potential underlying molecular mechanism involving hyperpolarization of the resting membrane potential and a series of calcium signaling is discussed.

description: Flexible graphene oxide (GO) microsheets with attached positively charged polymers, termed GOX microsheets, are efficient at bacterial adsorption, as they bind electrostatically to bacterial membranes’ negative surface charge. The authors explore an antimicrobial water filter application for GOX's extremely high surface area and its previously described efficient bacterial adsorption.Cellulose-fiber carrier material is functionalized with GOX microsheets to create an adsorption-based bacteria filtration material. The morphology and charge density (7.8 × 1019 g–1) of the prepared GOX fibers are determined by scanning electron microscopy and dye adsorption assay, and widefield fluorescence microscopy is used to visualize the adsorption of stained Escherichia coli bacterial cells on the fibers. GOX fibers are tested in filtration setups to investigate their bacteria removal performance. The experimental results, with 100 mg of GOX fibers filtering 2.4 × 109 colony-forming units (CFU) from an E. coli bacterial culture with 99.5% bacterial reduction, demonstrate the fibers’ high bacteria loading capacity. The electrostatic adsorption-based filtration mechanism allows the filter to be operated at higher flow rates than micropore membrane filters, while maintaining 3-log bacterial reduction. GOX filter materials removing bacteria via adsorption are a high flow rate alternative to current water filtration processes that rely on size-exclusion.

It specializes to the P_{33}(1232) resonance whose form factors are determined by theory and experiment and then are compared with experimental results at low and high energies. It is shown that the minimum in the low Q^2 region is a consequence of a combined effect from the vanishing of the vector form factors, the muon mass and Pauli blocking. Several improvements for the future investigations are suggested.

Leaching of chalcopyrite concentrate using extreme thermophilic bacteria
Creators: name: Timmins, Michael Glenn
Publisher: name: University of British Columbia
Year: 2009

description: The application of thermophilic bacteria to the leaching of a chalcopyrite (CuFeS2) concentrate from the Gibraltar Mine has been investigated in both shake flask and stirred tank reactor experiments. The conventional hydrometallurgical treatment of chalcopyrite is difficult due to a surface passivation phenomenon of the leaching particles. This passivation can be overcome through biological leaching at temperatures exceeding 50°C. The thermophilic leaching system is characterized by low temperatures (with respect to autoclave processes), high acidity and most importantly, a low redox potential. Due to the thermodynamic, chemical and biological properties inherent to high temperature bioleaching, the redox potential of the leaching slurry is held within the narrow potential range of 500 - 600 mV SHE. It is thought that in this range, chalcopyrite can be leached successfully. Of the various thermophilic species selected, a mixed thermophilic culture (growing at 70°C) outperformed all other thermophiles as well as the standard mesophile (growing at 35°C). It was observed that the thermophilic system is very sensitive to changes in temperature and consequently, leaching at the highest possible temperature (80-85°C) is advantageous. Inhibitions due to copper revealed that bacterial activity and therefore the leaching rate begins to be inhibited at copper concentrations above 10 g/L. Stirred tank reactor (STR) experiments resulted in copper extractions in excess of 90 % in 15 days. Approximately 75 to 99 % of the sulfide oxidized reported as elemental sulfur. It was found that the relative rates of leaching and the extent of sulfide oxidation (copper extraction) decreased with increasing pulp density over the range 2 to 10 %. Thermophilic bioleaching of the Gibraltar concentrate is thought to proceed under a biologically assisted indirect chemical leaching mechanism with the avoidance of chalcopyrite passivation as the result of low solution ORP.

description: We derive new algebraic attractor equations describing supersymmetric flux vacua of type IIB string theory. The first term in these equations, proportional to the gravitino mass (the central charge), is similar to the attractor equations for moduli fixed by the charges near the horizon of the supersymmetric black holes. The second term does not have a counterpart in the theory of black hole attractors. It is proportional to a mass matrix mixing axino-dilatino with complex structure modulino. This allows stabilization of moduli for vanishing central charge, which was not possible for BPS black holes. Finally, we propose a new set of attractor equations for non-supersymmetric black holes and for non-supersymmetric flux vacua.

description: The motivation for this study is the lack of knowledge of millers' preferences for noodle wheat in Asia, where noodle wheat is an expanding market segment. Data for the study are from interviews and questionnaires completed by millers in South Korea and Japan. Two different methodologies were applied--stated preference methods and semantic differential scales. Consistent results are seen from each method. Millers' choices of wheat with varying characteristics were analysed with multinomial logit models. These estimates are used to identify millers' preferred product profiles for various types of wheat and flour. Estimates are reported in the paper for millers' preferences for intrinsic quality features and trade contract terms for major types of wheat. Marginal analysis also yielded comparisons of millers' preferences in the two nations. In contrast to Australia and the United States, Canada does not produce or market a wheat variety that corresponds well to millers' preferred noodle wheat product profiles in terms of the wheat characteristics of falling number, protein level or dockage. Nor is Canada identified by millers in either of these nations as a preferred supplier of noodle wheat. Canada has a minor share of wheat exports to Korea but holds an appreciable share of Japanese wheat imports. However, Canada's market share of Japanese wheat imports may be more reflective of Japan's current regulated import process, rather than millers' preferences. Investment in product development and marketing will be necessary if Canada's share of the noodle wheat market in both Japan and Korea is to be increased.

description: In this paper a theoretical and empirical model is developed for analysing the decisions of individual farmers whether or not to produce wildlife and landscape services, how much of these services to produce and form an environmental co-operative in order to reduce transaction costs or to build up bargaining power. The model is applied for Dutch dairy farmers as the main users of agricultural land in the Netherlands. Simulations show that the reduction of transaction costs makes it attractive for farmers to form an environmental cooperative in case of a fixed price for wildlife and landscape services. Therefore more wildlife and landscape services are produced and more farmers are involved compared to a situation with individual supply. If demand is no longer perfectly elastic an increase in wildlife and landscape services production leads to lower prices offsetting part of the production and profit increase caused by lower transaction costs. However, if the environmental co-operative acts like a monopolist its bargaining position leads to a decrease in the production of wildlife and landscape services and higher prices.

description: We have evaluated the performance of a fine pitch CdTe Double-sided Strip Detector (CdTe-DSD), which was originally developed for the focal plane detector of a hard X-ray telescope to observe the Sun. The detector has a thickness of 750 um and has 128 strip electrodes with a 60 um strip pitch orthogonally placed on both sides of the detector and covers an energy range 4 keV to 80 keV. The study of the depth of photon interaction and charge sharing effects are of importance in order to provide good spectroscopic and imaging performance. We study the tail structure observed in the spectra caused by charge trapping and develop a new method to reconstruct the spectra based on induced charge information from both anode and cathode strips. By applying this method, energy resolutions (FWHM) of 0.76 keV and 1.0 keV can be obtained at photon energies of 14 keV and 60 keV, respectively, if the energy difference between the anode and cathode is within 1 keV. Furthermore, the tail component at 60 keV is reduced, and the energy resolution of the 60 keV peak is improved from 2.4 keV to 1.5 keV (FWHM) if the energy difference is greater than 1 keV. In order to study the imaging performance, we constructed a simple imaging system using a 5 mm thick tungsten plate that has a pinhole with a diameter of 100 um. We utilize a Ba-133 radioisotope of 1 mm in diameter as a target source in combination with a 100 um slit made from 0.5 mm thickness tungsten. We imaged the Ba-133 source behind the 100 um slit using a 30 keV peak, with a 100 um pinhole placed at the center of the source-detector distance. By applying a charge sharing correction between strips, we have succeeded in obtaining a position resolution better than the strip pitch of 60 um.

description: Uncertainty about the possibility of acquiring land can be rather large in the EU for sectors like dairy farming. Farm-level investment decisions are commonly made ex-ante when the farmer is not certain about the possibility of purchasing land. This possibility is realized only in a future period. In this paper, we have developed and applied a simple two-period model in which a profit-maximizing farmer, facing uncertainty about the possibility of acquiring land, had to choose the optimal mix of capital (buildings) investment and land endowment. We have shown that commonly "observed" biases towards non-optimal investment decisions are not necessarily justified. Rather, these perceived biases may be the result of evaluating investment decisions without reference to the uncertainty associated with the possibility of acquiring land.
Cardiomyopathy mutation alters end-to-end junction of tropomyosin and reduced calcium sensitivity

description: Muscle contraction is governed by tropomyosin (Tpm) shifting azimuthally between three states on F-actin (Blocked, Closed and Open) in response to calcium-binding to troponin and acto-myosin cross-bridge formation. The Tpm coiled coil polymerizes head-to-tail along the long-pitch helix of F-actin to form continuous super-helical cables that wrap around the actin filaments. The end-to-end bonds formed between the N- and C- terminus of adjacent Tpm molecules define Tpm continuity and play a critical role in the ability of Tpm to cooperatively bind to actin, thus facilitating Tpm conformational switching to cooperatively propagate along F-actin. We expect that a missense mutation in this critical overlap region associated with dilated cardiomyopathy, A277V, will alter tropomyosin binding and thin filament activation by altering the overlap structure. Here, we used co-sedimentation assays and in vitro motility assays to determine how the mutation alters Tpm binding to actin, and its ability to regulate acto-myosin interactions. Analytical viscometry coupled with molecular dynamics simulations showed that the A277V mutation results in enhanced Tpm end-to-end bond strength and a reduced curvature of the Tpm overlap domain. The mutant Tpm exhibited enhanced actin - Tpm binding affinity, consistent with overlap stabilization. The observed A277V-induced decrease in cooperative activation observed with regulated thin filament motility indicates that increased overlap stabilization is not correlated with Tpm-Tpm overlap binding strength or mechanical rigidity as is often assumed. Instead, A277V-induced structural changes result in local and delocalized increases in tropomyosin flexibility and prominent coiled-coil twisting in pseudorepeat 4. An A277V-induced decrease in Ca2+ sensitivity, consistent with a mutation-induced bolstering of B-state Tpm-actin electrostatic contacts and an increased TnT1 binding affinity, was also observed.

description: In this paper, we analyze the simultaneous regulation of several goods produced on agricultural land such as environmental amenities and crops. This analysis is conducted using a general two goods model where all agricultural land is used for production. The regulation authority can regulate these goods either through set aside requirements or production quotas. The paper focuses on information asymmetry about some farm performance index creating adverse selection. When public funds are non costly we show that the net social welfare induced by the two types of contracts are equal. In general we also show that if the goal of the regulation is to decrease the production of the quota good it is better to use the quota contract. On contrary if the regulation aims at increasing the production of the quota good, it is better to use a set aside contract.

description: The objective of this paper is to empirically detect credit rationing of Polish farms. Based on cross-sectional survey data and motivated by a microeconomic farm household model, this effort is pursued by a methodology consisting of three interrelated steps. These steps include the analysis of qualitative survey data regarding farmers' experience with bank credit, based on this an econometric estimation of internal shadow prices of credit for the credit constrained sub-sample of respondents, and finally an investigation of interdependencies between determinants of consumption and production that should be influenced by the presence of a binding credit constraint. The results of the empirical analysis consistently suggest that among the observed randomly selected Polish farms more than 40 percent of borrowers experience pronounced credit rationing by rural banks. These farms display internal shadow prices of the credit constraint of on average 190 percent net of principal. Shadow prices are significantly different from individual effective interest rates for credit that account for loan specific transaction costs. In the group of credit constrained farms, household characteristics could be proven to have a significant effect on output supply. This is evidence for a violation of separability between production and consumption decisions and thus lends empirical support to the existence of a binding credit constraint. Overall, credit constrained farm households own less and rent more land than the average, operate with a high capital intensity with regard to land, tend to have a poor credit history, and engage intensively in intra-village conversation. Generous government support via interest rate subsidisation apparently contributed little to alleviate credit rationing of farms in Poland.

description: In this paper a study is presented that had as goal to develop a management instrument (benchmarking)for co-innovation projects on basis of a set of performance indicators for chains and net-works of firms. To base the indicators on a sound basis relevant theories were studied, like industrial economics, resource-based theory, marketing theory, net-work theory and also specialised theories related to flexibility, innovation and quality care. Thereafter a framework was developed. The framework consist of a quick scan of performance measurement and comparative benchmarking to get a global idea of the possible improvements. For the aspects that need to be improved a more fine tuned approach is the measurement of performance related tot the different processes and a benchmark thereof. In the fine tuned part of the framework we distinguish capacities, realisation and perspectives. The quick scan part is used to get a global idea of the performance of different apple chains in The Netherlands, France and New-Zealand. It appeared to be a useful approach to get an idea about the performance of different chains with help of desk research and published information. Finally, some conclusions are drawn.
