description: The unconventional technologies, currently applied at a certain category of materials, difficult to be processed through usual techniques, have undergone during the last 60 years all the stages, since their discovery to their use on a large scale. They are based on elementary mechanisms which run the processing through classic methods, yet, they use in addition the interconnections of these methods. This leads to a plus in performance by increasing the outcomes precision, reducing the processing time, increasing the quality of the finite product, etc. This performance can be much increased by using the computer and a software product in assisting the human operator in the processing by an unconventional method such as; the electric or electro-chemical erosion, the complex electric-electro-chemical erosion, the processing by a laser fascicle and so on. The present work presents such an application based on a data base combining the previous experimental results, which proposes a method of optimization of the outcomes.

Cooperative Proxy Servers Architecture for VoD to Achieve High QoS with Reduced Transmission Time and Cost
Creators: name: Dakshayini, M.

description: - The aim of this paper is to propose a novel Voice On Demand (VoD) architecture and implementation of an efficient load sharing algorithm to achieve Quality of Service (QoS). This scheme reduces the transmission cost from the Centralized Multimedia Sever (CMS) to Proxy Servers (PS) by sharing the videos among the proxy servers of the Local Proxy Servers Group [LPSG] and among the neighboring LPSGs, which are interconnected in a ring fashion. This results in very low request rejection ratio, reduction in transmission time and cost, reduction of load on the CMS and high QoS for the users. Simulation results indicate acceptable initial startup latency, reduced transmission cost and time, load sharing among the proxy servers, among the LPSGs and between the CMS and the PS.

Le père Zeno Saltini et l’éducation du peuple à Nomadelfia: révolution et tradition d’un modèle de vie communautaire
Creators: name: Bandini, Gianfranco

description: The work of Don Zeno Saltini (1900-1981) is unique and fascinating and has endured the test of time. He was in fact a great (albeit solitary) innovator who, during the time of conflict, strongly contested the idea that orphaned children should be sent to institutions and colleges. He helped develop the concept of forming a community of families prepared to take on single children, offering them a whole “educating community” (Nomadelfia, founded in 1948). In 1968 the community obtained special permission from the Ministry of Public Education to create an experimental school run entirely by parents. Popular education is intended as a special, original form of acceptance: the people in question are those who choose a communal way of life involving no consumerism and no need for money or private property, and essentially based on fraternity.

Some observed statistical properties of small scale turbulence
Creators: name: Wilson, John Ronald
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this work was to investigate the characteristics of the small scales of the turbulent velocity and temperature fields in the atmospheric boundary layer. Of particular interest were the distributions of the spatial derivatives, the behaviour of the structure functions and the nature of the interactions leading to the inertial transfer of energy between the larger and smaller scales of the turbulent flow. The observed statistical distributions of the differentiated downstream and X-wire signals did not accurately conform to the theoretically predicted logarithmic normal model although there was good general agreement. The distribution of the sum of the squares of the differentiated X-wire signals was described extremely well by the log normal model. The temperature derivatives followed the log normal distribution somewhat better than did the velocity derivatives, but a poor signal to noise ratio prevented conclusive results. The observed structure functions conformed to present theory for the velocity and temperature data. The inertial transfer of energy in the downstream component was found to behave as would be intuitively expected. Specifically the net rate of arrival of energy was zero for wavenumbers where viscosity was unimportant and positive where viscosity was important. Interactions of scale sizes differing by more than a factor of ten in size did not contribute significantly to the energy transfers. The flow of downstream energy was observed to be from larger to smaller scale sizes for horizontal scales as large as twenty meters. The mean inertial transfer of energy associated with interactions between downstream components only, was found to be approximately equal to the mean rate of energy loss due to the corresponding dissipation term.

description: We have performed a metrological characterization of the quantum Hall resistance in a 1 $μ$m wide graphene Hall-bar. The longitudinal resistivity in the center of the $ν=\pm 2$ quantum Hall plateaus vanishes within the measurement noise of 20 m$Ω$ upto 2 $μ$A. Our results show that the quantization of these plateaus is within the experimental uncertainty (15 ppm for 1.5$ μ$A current) equal to that in conventional semiconductors. The principal limitation of the present experiments are the relatively high contact resistances in the quantum Hall regime, leading to a significantly increased noise across the voltage contacts and a heating of the sample when a high current is applied.

description: While colloidal chemistry provides ways to obtain a great variety of nanoparticles, with different shapes, sizes, material composition, and surface functions, their controlled deposition and combination on arbitrary positions of substrates remains a considerable challenge. Over the last ten years, optical printing arose as a versatile method to achieve this purpose for different kinds of nanoparticles. In this article we review the state of the art of optical printing of single nanoparticles, and discuss its strengths, limitations, and future perspectives, by focusing on four main challenges: printing accuracy, resolution, selectivity, and nanoparticles photostability.

A Born-Oppenheimer Expansion in a Neighborhood of a Renner-Teller Intersection
Creators: name: Herman, Mark S.
Publisher: name: arXiv
Year: 2009
Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: We perform a rigorous mathematical analysis of the bending modes of a linear triatomic molecule that exhibits the Renner-Teller effect. Assuming the potentials are smooth, we prove that the wave functions and energy levels have asymptotic expansions in powers of epsilon, where epsilon^4 is the ratio of an electron mass to the mass of a nucleus. To prove the validity of the expansion, we must prove various properties of the leading order equations and their solutions. The leading order eigenvalue problem is analyzed in terms of a parameter b, which is equivalent to the parameter originally used by Renner. For 0 < b < 1, we prove self-adjointness of the leading order Hamiltonian, that it has purely discrete spectrum, and that its eigenfunctions and their derivatives decay exponentially. Perturbation theory and finite difference calculations suggest that the ground bending vibrational state is involved in a level crossing near b = 0.925. We also discuss the degeneracy of the eigenvalues. Because of the crossing, the ground state is degenerate for 0 < b < 0.925 and non-degenerate for 0.925 < b < 1.

description: 2-Ethyhexyl nitrate (2-EHN) is a major additive of fuel which is used to comply with the cetane number of diesel. Because of its wide use and possible accidental release, 2-EHN is a potential pollutant of the environment. In this study, Mycobacterium austroafricanum IFP 2173 was selected among several strains as the best 2-EHN degrader. The 2-EHN biodegradation rate was increased in biphasic cultures where the hydrocarbon was dissolved in an inert non-aqueous phase liquid (NAPL), suggesting that the transfer of the hydrophobic substrate to the cells was a growth-limiting factor. Carbon balance calculation as well as organic carbon measurement indicated a release of metabolites in the culture medium. Further analysis by gas chromatography revealed that a single metabolite accumulated during growth. This metabolite had a molecular mass of 114 Da as determined by GC/MS and was provisionally identified as 4-ethyldihydrofuran-2(3H)-one by LC-MS/MS analysis. Identification was confirmed by analysis of the chemically synthesized lactone. Based on these results, a plausible catabolic pathway is proposed whereby 2-EHN is converted to 4-ethyldihydrofuran-2(3H)-one, which cannot be metabolised further by strain IFP 2173. This putative pathway provides an explanation for the low energetic efficiency of 2-EHN degradation and its poor biodegradability.

description: The next generation of space systems will have to achieve more and more complex missions. In order to master the development cost and duration of such systems, an alternative to a manual design is to automatically synthesize the main parameters of the system. In this paper, we present an approach for the specific case of the scheduling of the flight control of a space launcher. The approach requires two successive steps: (1) the formalization of the problem to be solved in a parametric formal model and (2) the synthesis of the model parameters with a tool. We first describe the problem of the scheduling of a launcher flight control, then we show how this problem can be formalized with parametric stopwatch automata; we then present the results computed by the parametric timed model checker IMITATOR. We enhance our model by taking into consideration the time for switching context, and we compare the results to those obtained by other tools classically used in scheduling.

description: We report on observations of the dust trail of comet 67P/Churyumov-Gerasimenko (CG) in visible light with the Wide Field Imager at the ESO/MPG 2.2m telescope at 4.7 AU before aphelion, and at 24 micron with the MIPS instrument on board the Spitzer Space Telescope at 5.7 AU both before and after aphelion. The comet did not appear to be active during our observations. Our images probe large dust grains emitted from the comet that have a radiation pressure parameter beta<0.01. We compare our observations with simulated images generated with a dynamical model of the cometary dust and constrain the emission speeds, size distribution, production rate and geometric albedo of the dust. We achieve the best fit to our data with a differential size distribution exponent of -4.1, and emission speeds for a beta=0.01 particle of 25 m/s at perihelion and 2 m/s at 3 AU. The dust production rate in our model is on the order of 1000 kg/s at perihelion and 1 kg/s at 3 AU, and we require a dust geometric albedo between 0.022 and 0.044. The production rates of large (>10 micron) particles required to reproduce the brightness of the trail are sufficient to also account for the coma brightness observed while the comet was inside 3 AU, and we infer that the cross-section in the coma of CG may be dominated by grains of the order of 60-600 micron.

The MOND limit from space-time scale invariance

Subjects: subject: Astrophysics (astro-ph)

description: The MOND limit is shown to follow from a requirement of space-time scale invariance of the equations of motion for nonrelativistic, purely gravitational systems; i.e., invariance of the equations of motion under (t,r) goes to (qt,qr), in the limit a0 goes to infinity. It is suggested that this should replace the definition of the MOND limit based on the low-acceleration behavior of a Newtonian-MOND interpolating function. In this way, the salient, deep-MOND results--asymptotically flat rotation curves, the mass-rotational-speed relation (baryonic Tully-Fisher relation), the Faber-Jackson relation, etc.--follow from a symmetry principle. For example, asymptotic flatness of rotation curves reflects the fact that radii change under scaling, while velocities do not. I then comment on the interpretation of the deep-MOND limit as one of "zero mass": Rest masses, whose presence obstructs scaling symmetry, become negligible compared to the "phantom", dynamical masses--those that some would attribute to dark matter. Unlike the former masses, the latter transform in a way that is consistent with the symmetry. Finally, I discuss the putative MOND-cosmology connection in light of another, previously known symmetry of the deep-MOND limit. In particular, it is suggested that MOND is related to the asymptotic de Sitter geometry of our universe. It is conjectured, for example, that in an exact de Sitter cosmos, deep-MOND physics would exactly apply to local systems. I also point out, in this connection, the possible relevance of a de Sitter-conformal-field-theory (dS/CFT) duality.

New cross section measurements for the reaction ¹⁶0(p,γ)¹⁷F with an extrapolation to astrophysical energies
Creators: name: Hall, Thomas Hammond
Publisher: name: University of British Columbia
Year: 2010

description: Improved absolute cross section and angular distribution measurements have been made for the direct radiative capture of protons by ¹⁶0. Gamma ray yields have been obtained at four center of mass energies from 1.288 to 2.404 Mev for direct capture to the d⁺[sub 5/2] ground state of ¹⁷F and at seven center of mass energies from 0.795 to 2.404 Mev for direct capture to the s⁺[sub 1/2] first excited state. Angular distribution data have been obtained for both transitions for three angles at 0.778 Mev and four angles at each of 1.289, 1.840 and 2.306 Mev in the center of mass. In addition, separate measurements have determined differential cross sections to ± 0.5% for the elastic scattering of protons by ¹⁶0 at 171°.5 in the center of mass from the energy region of pure Rutherford scattering to 2.0 Mev bombarding energy. The direct capture cross section was normalized to the elastic scattering cross section by a technique which allowed simultaneous observation of both reactions. This was made feasible by the development of transmission targets consisting of a layer of WO₃ sputtered onto a self-supporting gold backing. A large volume Ge(Li) detector was used to observe the gamma rays and to provide accurate measurements of the gamma ray yields. The present measurements agree to within 5% with the most recent cross section calculations of Chow (1973). The reaction ¹⁶0(p,γ)¹⁷F is important in stellar astrophysics through the role it plays in the CN0 bi-cycle. Its cross section at stellar energies affects the relative abundances of the catalyst nuclei carbon, nitrogen and oxygen in those stars which are burning hydrogen by this cycle of reactions. By lending confidence to, and providing an accurate normalization for the direct capture calculations, the present measurements allow a reliable extrapolation of the theory to stellar thermal energies. For center of mass energies below 100 Kev, the contributions to the astrophysical S-factor from capture to the l/2⁺ first excited state and the 5/2⁺ ground state of ¹⁷F can be expressed as S [sub (l/2⁺ state)] (E) = (9.245 – 0.0329E + 0.00007E2) ± 4.1% Kev barns S [sub (5/2⁺ state)] (E) = (0.302 + 0.0002E) ± 6.8% Kev barns. The large energy dependence of S [sub (1/2⁺ state)], in particular its dramatic increase with decreasing energy in the region of thermal energy, arises from the low binding energy of the l/2⁺ first excited state. Consequently, the ¹⁶0(p,γ)¹⁷F reaction rate at stellar thermal energies is determined almost entirely by direct capture to this state.

Stabilized-jellium description of neutral and multiply charged fullerenes

subject: FOS: Physical sciences

description: A description of neutral and multiply charged fullerenes is proposed based on a stabilized jellium (structureless pseudopotential) approximation for the ionic background and the local density approximation for the sigma and pi valence electrons. A recently developed shell-correction method is used to calculate total energies and properties of both the neutral and multiply charged anionic and cationic fullerenes. The effect of the icosahedral symmetry is included perturbatively. The calculated single-particle energy level spectrum of C_60 is in good correspondence with experimentally measured ones and previous self-consistent local-density-approximation calculations. For the multiply charged fullerenes, we calculate microscopically the charging energies for up to 12 excess charges. A semiclassical interpretation of these results is developed, which views the fullerenes as Coulomb islands possessing a classical capacitance. The calculated values for the first ionization potential and the first electron affinity agree well with the experimental ones. Our calculations support the results from charge transfer bracketing experiments and from direct ionization experiments through electron impact. The doubly charged negative ion is found to be a very long-lived metastable species, in agreement with observations.
description: In addition to the zero-node (sigma) and one-node (pi) orbitals, this early (1994) jellium study described three two-node (delta) orbitals that are delocalized within the fullerene-cage cavity. Such superatom/central-potential two-node orbitals have been recently observed experimentally

description: We present a methodology to address, from first principles, charge-spin interconversion in two-dimensional materials with spin-orbit coupling. Our study relies on an implementation of density functional theory based quantum transport formalism adapted to such purpose. We show how an analysis of the $k$-resolved spin polarization gives the necessary insight to understand the different charge-spin interconversion mechanisms. We have tested it in the simplest scenario of isolated graphene in a perpendicular electric field where effective tight-binding models are available to compare with. Our results show that the flow of an unpolarized current across a single layer of graphene produces, as expected, a spin separation perpendicular to the current for two of the three spin components (out-of-plane and longitudinal), which is the signature of the spin Hall effect. Additionally, it also yields an overall spin accumulation for the third spin component (perpendicular to the current), which is the signature of the Rashba-Edelstein effect. Even in this simple example, our results reveal an unexpected competition between the Rashba and the intrinsic spin-orbit coupling. Remarkably, the sign of the accumulated spin density does not depend on the electron or hole nature of the injected current for realistic values of the Rashba coupling.

Pauli blocking and final-state interaction in electron-nucleus quasielastic scattering
Creators: name: Lon-Chang
name: Liu
Publisher: name: arXiv
Year: 2009
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: The nucleon final-state interaction in inclusive electron-nucleus quasielastic scattering is studied. Based on the unitarity equation satisfied by the scattering-wave operators, a doorway model is developed to take into account the final-state interaction including the Pauli blocking of nucleon knockout. The model uses only experimental form factors as the input and can be readily applied to light- and medium-mass nuclei. Pauli blocking effects in these latter nuclei are illustrated with the case of the Coulomb interaction. Significant effects are noted for beam energies below ~ 350 MeV and for low momentum transfers.

An imploding detonation expansion laser
Creators: name: Armstrong, Bruce Allan
Publisher: name: University of British Columbia
Year: 2010

description: An imploding detonation expansion laser has been built and some preliminary work has been done to determine its properties. Optical and pressure measurements were performed both in the detonation chamber and the nozzle. Gain measurements at CO and CO2 wavelengths were made as a function of starting mixture, throat height and position in the nozzle. A brief attempt to make the system lase was not successful. More effort will be expended after repairs to the machine have been made.

$η/s$ of a Relativistic Hadron Gas at RHIC: Approaching the AdS/CFT bound?

description: Ultrarelativistic heavy-ion collisions at the Relativistic Heavy Ion Collider (RHIC) are thought to have produced a state of matter called the quark-gluon plasma, characterized by a very small shear-viscosity to entropy-density ratio $η/s$, near the lower bound predicted for that quantity by AdS/CFT methods. As the produced matter expands and cools, it evolves through a phase described by a hadron gas with rapidly increasing $η/s$. We calculate $η/s$ as a function of temperature in this phase both in and out of chemical equilibrium and find that its value poses a challenge for viscous relativistic hydrodynamics, which requires small values of $η/s$ in order to successfully describe the collective flow observables at RHIC. We therefore conclude that the origin of the low viscosity matter at the RHIC must be in the partonic phase of the reaction.

description: White dwarf masses in cataclysmic variables are difficult to determine accurately, but are fundamental for understanding binary system parameters, as well as binary evolution. We investigate the X-ray spectral properties of a sample of Intermediate Polars detected above 15 keV to derive the masses of their accreting white dwarfs. We use data from the Swift/BAT instrument which during the first 2.5 yrs of operation has detected 22 known intermediate polars. The X-ray spectra of these sources are used to estimate the mass of the white dwarfs. We are able to produce a mass estimate for 22 out of 29 of the confirmed intermediate polars. Comparison with previous mass measurements shows good agreement. For GK Per, we were able to detect spectral changes due to the changes in the accretion rate. The Swift/BAT detector with its combination of sensitivity and all-sky coverage provides an ideal tool to determine accurate white dwarf masses in intermediate polars.

description: The medicinal properties of narcissus plants are attributed to the presence of Amaryllidaceae alkaloids. Elicitors, such as nanoparticles, are employed to enhance the production of secondary metabolites through signaling and the generation of reactive oxygen species. We investigated the effects of Fe3O4 nanoparticles (Fe3O4-NPs), trans-cinnamic acid (tCA), and L-phenylalanine (L-Phe) precursors on various physiological and biochemical parameters in Narcissus tazetta L., with a particular focus on alkaloid content. Fe3O4- NPs treatment significantly increased photosynthetic pigments, secondary metabolites (including alkaloids, and phenolic compounds), total soluble carbohydrates, and polysaccharides. The activities of antioxidant enzymes (SOD, CAT, POD), phenylalanine ammonia-lyase (PAL), and tyrosine ammonia-lyase (TAL) enhanced under Fe3O4-NPs treatment. While tCA treatment led to an increase in H2O2 levels, L-Phe treatment decreased it. Both elicitors influenced the plant’s metabolism, promoting primary and secondary metabolites. The augmentation of photosynthetic pigment content and antioxidant enzyme activity induced by tCA and L-Phe treatments appeared to improve alkaloid production. Furthermore, in silico studies using Molegro Virtual Docker (MVD) software were conducted. The third structures of PAL and N4OMT enzymes were designed by Modeler software and the ligand structures were designed using ChemDraw® (Fe3O4) and Atomsk (precursors) software. Docking results revealed that the Fe3O4-NPs and precursors interacted with the active sites of PAL and N4OMT, two enzymes involved in alkaloid biosynthesis in narcissus, exhibiting varying binding energies and impacting their activities. The Fe3O4/N4OMT and L-phenylalanine/PAL complexes had higher free energies of binding. Our results indicated that Fe3O4-NPs and precursors significantly affected the gene expressions of PAL and N4OMT. The highest levels of PAL (after 96 h) and N4OMT (after 24 h) expressions were obtained in tCA + Fe3O4-NPs and L-Phe + Fe3O4-NPs treatments. In summary, the application of Fe3O4-NPs, tCA, and L-Phe demonstrated the potential to activate the production of secondary metabolites, including alkaloids, by modulating the plant’s metabolic pathways.
Singularities in inflationary cosmological models

description: Due to the accelerated expansion of the universe, the possibility of formation of singularities has changed from the classical Big Bang and Big Crunch singularities to include a number of new scenarios. In recent papers it has been shown that such singularities may appear in inflationary cosmological models with a fractional power scalar field potential. In this paper we enlarge the analysis of singularities in scalar field cosmological models by the use of generalised power expansions of their Hubble scalar and their scalar field in order to describe all possible models leading to a singularity, finding other possible cases. Unless a negative scalar field potential is considered, all singularities are weak and of type IV.

description: We report an analysis of intramolecular dynamics of the highly excited planar carbonyl sulfide (OCS) below and at the dissociation threshold by the Fast Lyapunov Indicator (FLI) method. By mapping out the variety of dynamical regimes in the phase space of this molecule, we obtain the degree of regularity of the system versus its energy. We combine this stability analysis with a periodic orbit search, which yields a family of elliptic periodic orbits in the regular part of phase space an a family of in-phase collinear hyperbolic orbits associated with the chaotic regime.

description: Context : On its asteroseismic side, the initial run of CoRoT was partly devoted to the solar like star HD49933.The eigenmodes of this F dwarf have been observed with unprecedented accuracy. Aims : We investigate quantitatively the impact of changes in the modeling parameters like mass and composition. More importantly we investigate how a sophisticated physics affects the seismological picture of HD49933. We consider the effects of diffusion, rotation and the changes in convection efficiency. Methods : We use the CESAM stellar evolution code coupled to the ADIPLS adiabatic pulsation package to build secular models and their associated oscillation frequencies. We also exploited the hydrodynamical code STAGGER to perform surface convection calculations. The seismic variables used in this work are : the large frequency separation, the derivative of the surface phase shift,and the eigenfrequencies $\rm ν_{\ell=0,n=14}$ and $\rm ν_{\ell=0,n=27}$. Results : Mass and uncertainties on the composition have much larger impacts on the seismic variables we consider than the rotation. The derivative of the surface phase shift is a promising variable for the determination of the helium content. The seismological variables of HD49933 are sensitive to the assumed solar composition and also to the presence of diffusion in the models.
