Logarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection
No full textWe report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either
Alcohol Dehydrogenase Biosensor based on Poly (Aniline)-Poly (Vinylsulfonate) modified electrode and enhancement effect of CA2+ ions on the Electrocatalytic oxidation of NADH at Poly(Aniline)-Poly (Vinylsulfonate) and Poly (Aniline)-Poly (Styrenesulfonate) modified Electrodes
No full textA membrane enzyme electrode sensitive towards ethanol was fabricated based on poly(aniline)-poly(vinylsulfonate) modified electrodes. Using the membrane electrode design and by varying the physical parameters, we established that the membrane enzyme electrode current response was consistent with a reversible enzyme kinetic model. Under conditions in which the product concentration was negligible within the enzyme layer of the enzyme electrode, the substrate-dependent current response could be described using a coupled reaction-diffusion model based on irreversible enzyme kinetics. This is the first report on the use of poly(aniline) modified electrodes as amperoraetric biosensors for the detection of ethanol. In the second part of this work, we investigated the enhancement of steady-state current towards NADH at poly(aniline)-poly(vinylsulfonate) and poly(aniline)- poly(styrenesulfonate) modified electrodes in the presence of calcium ions, using electrochemical methods, ^'P NMR and kinetic modelling. We observed reversible binding between Ca^^ and poly(aniline)-poly(vinylsulfonate) from cyclic voltammetry and steady- state experiments. The enhancement of electrocatalytic current towards NADH in the presence of between 20 and 40 mM Ca^^ were about 12 and 27 times for thin films of poly(aniline)-poly(vinylsulfonate) and poly(aniline)-poly(styrenesulfonate), respectively. This enhancement effect of Ca^^ ions on the electrocatalytic oxidation of NADH at poly(aniline) modified electrodes was much greater than those observed by workers using other mediators. From kinetic modelling of the experimental data, we found that the enhancement effect of Ca^^ ions was due to a large change in the polymer binding affinity for NADH or partitioning of NADH into the polymer film. The binding energy gain was estimated to be about 14 kJ m o f' in the presence of 25 mM Ca^^. This was confirmed by measurements using solid state ^'P NMR which indicated that NADH accumulated in the polymer film only in the presence of Ca^^.</p
Prime values of and , quadratic
No full textWe prove an asymptotic formula for primes of the shape with integers and of the shape with prime. Here is a binary quadratic form with integer coefficients, irreducible over and has no local obstructions. This refines the seminal work of Friedlander and Iwaniec on primes of the form and Heath-Brown and Li on primes of the form , as well as earlier work of the author with Lam and Schindler on primes of the form with a positive definite form.45 page
A 2 h periodic variation in the low-mass X-ray binary Ser X-1
No full textSpectroscopy of the low-mass X-ray binary Ser X-1 using the Gran Telescopio Canarias have revealed a ?2 h periodic variability that is present in the three strongest emission lines. We tentatively interpret this variability as due to orbital motion, making it the first indication of the orbital period of Ser X-1. Together with the fact that the emission lines are remarkably narrow, but still resolved, we show that a main-sequence K dwarf together with a canonical 1.4 M? neutron star gives a good description of the system. In this scenario, the most likely place for the emission lines to arise is the accretion disc, instead of a localized region in the binary (such as the irradiated surface or the stream-impact point), and their narrowness is due instead to the low inclination (?10°) of Ser X-1

Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
