The Benefits of Being Economics Professor A (and not Z)
No full textAlphabetic name ordering on multi-authored academic papers, which is the convention in the economics discipline and various other disciplines, is to the advantage of people whose last name initials are placed early in the alphabet. As it turns out, Professor A, who has been a first author more often than Professor Z, will have published more articles and experienced afaster growth rate over the course of her career as a result of reputation and visibility. Moreover, authors know that name ordering matters and indeed take ordering seriously: Several characteristics of an author group composition determine the decision to deviate from the default alphabetic name order to a significant extent.performance measurement, incentives, economists, name ordering

Superconducting quantum point contacts and Maxwell potential
No full textThe quantization of the current in a superconducting quantum point contact is reviewed and the critical current is discussed at different temperatures depending on the carrier concentration as well by suggesting a constant potential in the semiconductor and then a Maxwell potential. When the Fermi wavelength is comparable with the constriction width we showed that the critical current has a step-like variation as a function of the constriction width and the carrier concentration. © World Scientific Publishing Company.Abdalla E, 1998, PHYS REV LETT, V80, P238, DOI 10.1103-PhysRevLett.80.238; AKAZAKI T, 1991, APPL PHYS LETT, V59, P2037, DOI 10.1063-1.106124; ALY AH, 1998, EGYPTIAN J PHYS, V70, P35; ANDREEV AF, 1964, SOV PHYS JETP-USSR, V19, P1228; Andreev A.F., 1964, Zhurnal Eksperimental'noi i Teoreticheskoi Fiziki, V46; BARDEEN J, 1972, PHYS REV B, V5, P72, DOI 10.1103-PhysRevB.5.72; Bauch T, 2005, PHYS REV B, V71, DOI 10.1103-PhysRevB.71.174502; BECKER T, 1995, PHYSICA B, V204, P183, DOI 10.1016-0921-4526(94)00261-S; Chang VCY, 1997, PHYS REV B, V55, P6004, DOI 10.1103-PhysRevB.55.6004; CHRESTIN A, 1994, PHYS REV B, V49, P498, DOI 10.1103-PhysRevB.49.498; Chtchelkatchev NM, 2000, PHYS REV B, V62, P3559, DOI 10.1103-PhysRevB.62.3559; Colatto LP, 2003, PHYS LETT A, V314, P184, DOI 10.1016-S0375-9601(03)00903-4; Dai Z, 2006, APPL PHYS LETT, V88, DOI 10.1063-1.2206697; De Franceschi S, 1998, APPL PHYS LETT, V73, P3890, DOI 10.1063-1.122926; DEGENNES PG, 1995, SUPERCONDUCTIVITY ME, pCH5; DESER S, 1982, ANN PHYS-NEW YORK, V140, P372, DOI 10.1016-0003-4916(82)90164-6; DUNNE GV, HEPTH9902115; FROLOV SM, 2004, MAT04042434; FURUSAKI A, 1991, PHYS REV LETT, V67, P132, DOI 10.1103-PhysRevLett.67.132; FURUSAKI A, 1998, CONDMAT9811026; FURUSAKI A, 1992, PHYS REV B, V45, P10563, DOI 10.1103-PhysRevB.45.10563; Giazotto F, 2001, APPL PHYS LETT, V78, P1772, DOI 10.1063-1.1357211; Imamura H, 2002, J APPL PHYS, V91, P7032, DOI 10.1063-1.1447188; ISHII C, 1970, PROG THEOR PHYS, V44, P1525, DOI 10.1143-PTP.44.1525; ISHII C, 1972, PROG THEOR PHYS, V47, P1464, DOI 10.1143-PTP.47.1464; KASTALSKY A, 1991, PHYS REV LETT, V67, P3026, DOI 10.1103-PhysRevLett.67.3026; Khare A, 1998, FRACTIONAL STAT QUAN; Kikuchi K., 2002, Physical Review B (Condensed Matter and Materials Physics), V65, DOI 10.1103-PhysRevB.65.020508; KLAPWIJK TM, 1994, PHYSICA B, V197, P481, DOI 10.1016-0921-4526(94)90248-8; KULIK IO, 1970, SOV PHYS JETP-USSR, V30, P944; Lachenmann SG, 1998, J APPL PHYS, V83, P8077, DOI 10.1063-1.367905; MAGNEE PHC, 1994, PHYS REV B, V50, P4594, DOI 10.1103-PhysRevB.50.4594; NGUYEN C, 1994, APPL PHYS LETT, V65, P103, DOI 10.1063-1.113047; NITTA J, 1992, PHYS REV B, V46, P14286, DOI 10.1103-PhysRevB.46.14286; Poirier W, 1997, PHYS REV LETT, V79, P2105, DOI 10.1103-PhysRevLett.79.2105; Regul J, 2002, APPL PHYS LETT, V81, P2023, DOI 10.1063-1.1506417; STERN J, 1991, PHYS LETT B, V265, P119, DOI 10.1016-0370-2693(91)90024-K; SVIDZINS.AV, 1973, J LOW TEMP PHYS, V10, P131, DOI 10.1007-BF00655245; Sze S.

Chemical characterization, antioxidant and inhibitory effects of some marine sponges against carbohydrate metabolizing enzymes
No full textUNLABELLED: BACKGROUND: More than 15,000 marine products have been described up to now; Sponges are champion producers, concerning the diversity of products that have been found. Most bioactive compounds from sponges were classified into anti-inflammatory, antitumor, immuno- or neurosurpressive, antiviral, antimalarial, antibiotic, or antifouling. Evaluation of in vitro inhibitory effects of different extracts from four marine sponges versus some antioxidants indices and carbohydrate hydrolyzing enzymes concerned with diabetes mellitus was studied. The chemical characterizations for the extracts of the predominating sponges; SP1 and SP3 were discussed. METHODS: All chemicals served in the biological study were of analytical grade and purchased from Sigma, Merck and Aldrich. All kits were the products of Biosystems (Spain), Sigma Chemical Company (USA), Biodiagnostic (Egypt). Carbohydrate metabolizing enzymes; α-amylase, α-glucosidase, and β-galactosidase (EC3.2.1.1, EC3.2.1.20, and EC3.2.1.23, respectively) were obtained from Sigma Chemical Company (USA). RESULTS: Four marine sponges; Smenospongia (SP1), Callyspongia (SP2), Niphates (SP3), and Stylissa (SP4), were collected from the Red Sea at Egyptian coasts, and taxonomically characterized. The sponges' extracts exhibited diverse inhibitory effects on oxidative stress indices and carbohydrate hydrolyzing enzymes in linear relationships to some extent with concentration of inhibitors (dose dependant). The extracts of sponges (3, 1, and 2) showed, respectively, potent-reducing power. Purification and Chemical characterization of sponge 1 using NMR and mass spectroscopy, recognized the existence of di-isobutyl phthalate (1), di-n-butyl phthalate (2), linoleic acid (3), β-sitosterol (4), and cholesterol (5). Sponge 3 produced bis-[2-ethyl]-hexyl-phthylester (6) and triglyceride fatty acid ester (7). CONCLUSION: Marine sponges are promising sources for delivering of bioactive compounds. Four marine sponges, collected from Red Sea at Egyptian coasts, were identified as Smenospongia (SP1), Callyspongia (SP2), Niphates (SP3), and Stylissa (SP4). The results demonstrated that different sponges extracts exhibited inhibitory effects on oxidative stress indices and carbohydrate hydrolyzing enzymes in linear relationships to some extent with concentration of inhibitors (dose dependant). The extracts of sponges (3, 1, and 2) showed, respectively, potent-reducing power. Chemical characterizations of sponges SP1 and SP3 were discussed. Based on this study, marine sponges are considered as talented sources for production of diverse and multiple biologically active compounds
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
Statistics of the subgrid scales after the shock-turbulence interaction
No full textThe interaction of a normal shock with isotropic turbulence (IT) represents a basic problem for studying some of the phenomena associated with high speed flows, such as hypersonic flight, supersonic combustion and Inertial Confinement Fusion (ICF). In general, in practical applications, the shock width is much smaller than the turbulence scales and the upstream turbulent Mach number is modest. In this case, recent high resolution shock-resolved Direct Numerical Simulations (DNS) (Ryu and Livescu, J. Fluid Mech., 756, R1, 2014) show that the interaction can be described by the Linear Interaction Approximation (LIA). By using LIA to alleviate the need to solve the shock, DNS post-shock data can be generated at much higher Reynolds numbers than previously possible. Here, such results with Taylor Reynolds number around are used to investigate the properties of the subgrid scales (SGS). In particular, it is shown that the shock interaction decreases the asymmetry of the SGS dissipation PDF as the shock Mach number increases, with a significant enhancement in size of the regions and magnitude of backscatter

Transition to turbulence in a qblique shock-wave/boundary-layer interaction at M=15
No full textDirect numerical simulations are carried out for different forcing techniques to trigger transition during the interaction between an oblique shock-wave and a laminar boundary-layer at M = 1.5. Three forcing methods are used: a) forcing of oblique unstable modes, whose shape and behaviour are determined by the local linear stability theory, b) broadband free-stream acoustic disturbances, and c) a cold plasma flow control device. While the oblique-mode breakdown is dominant for low-amplitude forcing, long streaky structures drive the transition process in a high-amplitude disturbance environment. LES are also performed on the experimental setup by the Institute of Theoretical and Applied Mechanics (ITAM) from Novosibirsk State University with cold plasma actuation. As well as the disturbance type, the effect of Reynolds number and forcing amplitude will be investigated
