Constraints on massive neutrinos from the CFHTLS angular power spectrum

We use the galaxy angular power spectrum at z ∼ 0.5–1.2 from the Canada-France-Hawaii-Telescope Legacy Survey Wide fields (CFHTLS-Wide) to constrain separately the total neutrino mass ∑mν and the effective number of neutrino species Neff. This survey has recently benefited from an accurate calibration of the redshift distribution, allowing new measurements of the (non-linear) matter power spectrum in a unique range of scales and redshifts sensitive to neutrino free streaming. Our analysis makes use of a recent model for the effect of neutrinos on the weakly non-linear matter power spectrum derived from accurate N-body simulations. We show that CFHTLS, combined with WMAP7 and a prior on the Hubble constant provides an upper limit of ∑mν < 0.29 eV and Neff = 4.17+1.62−1.26 (2 σ confidence levels). If we omit smaller scales which may be affected by non-linearities, these constraints become ∑mν < 0.41 eV and Neff = 3.98+2.02−1.20 (2 σ confidence levels). Finally we show that the addition of other large scale structures probes can further improve these constraints, demonstrating that high redshift large volumes surveys such as CFHTLS are complementary to other cosmological probes of the neutrino mass.
Influence of time-periodic potentials on electronic transport in double-well structure

Within the framework of the Floquet theorem, we have investigated single-electron photon-assisted tunneling in a double-well system using the transfer matrix technique. The transmission probability displays satellite peaks on both sides of the main resonance peaks and these satellite peaks originate from emission or absorption photons. The single-electron resonance tunneling can be controlled through changing the applied harmonically potential positions, such as driven potential in wells, in barriers, or in whole double-well systems. This advantage should be useful in the optimization of the parameters of a transmission device.
On the rigidity of a hard-sphere glass near random close packing

We study theoretically and numerically the microscopic cause of the rigidity of hard-sphere glasses near their maximum packing. We show that, after coarse-graining over time, the hard-sphere interaction can be described by an effective potential which is exactly logarithmic at the random close packing ϕc. This allows to define normal modes, and to apply recent results valid for elastic networks: rigidity is a non-local property of the packing geometry, and is characterized by some length scale l* which diverges at ϕc (Wyart M., Nagel S. R. and Witten T. A., Europhys. Lett., 72 (2005) 486; Wyart M. , Silbert L. E. , Nagel S. R. and Witten T. A. , Phys. Rev. E, 72 (2005) 051306). We compute the scaling of the bulk and shear moduli near ϕc, and speculate on the possible implications of these results for the glass transition.
Infrared emissivities of Mn, Co co-doped ZnO powders

Infrared emissivities of Zn0.99−xMn0.01CoxO (x = 0.00, 0.01, 0.03, 0.05) powders synthesized at different calcination temperatures by solid-state reaction are investigated. Their phases, morphologies, UV absorption spectra, and infrared emissivities are studied by XRD, SEM, UV spectrophotometer, and an IR-2 dual-band infrared emissometer in a range of 8 μm–14 μm. Doped ZnO still has a wurtzite structure, and no peaks of other phases originating from impurities are detected. The optical band-gap decreases as the Co content and calcination temperature ascend, and of which the smallest optical band gap is 2.19 eV. The lowest infrared emissivity, 0.754, is observed in Zn0.98Mn0.01Co0.01O with the increase in Co concentration. The infrared emissivity experiences fluctuations as the calcination temperature increases, and its minimum value is 0.762 at 1100 °C.
Comprehending ecological and economic sustainability

The global environmental imperative demands urgent actions on ecological stabilization, yet the global scale of such actions is persistently insufficient. This calls for investigating why the world economy appears to be so fearful of any potential environmental expenditure. Using the formalism of Lyapunov potential function it is shown that the stability principles for biomass in the ecosystem and for employment in economics are mathematically similar. The ecosystem has a stable and unstable stationary state with high (forest) and low (grasslands) biomass, respectively. In economics, there is a stable stationary state with high employment in mass production of conventional goods sold at low cost price, and an unstable stationary state with lower employment in production of novel products of technological progress sold at higher prices. An additional stable state is described for economics with very low employment in production of life essentials, such as energy and raw materials that are sold at greatly inflated prices. In this state the civilization pays 10% of global GDP for energy produced by a negligible minority of the working population (currently ∼0.2%) and sold at prices exceeding the cost price by 40 times, a state when any extra expenditures of whatever nature appear intolerable. The reason lies in the fundamental shortcoming of economic theory, which allows for economic ownership over energy sources. This is shown to be equivalent to equating measurable variables of different dimensions (stores and fluxes), which leads to effective violation of the laws of energy and matter conservation in modern economics.
Small-scale recombination He — Sr+(Ca+ ) lasers

A review of specific features and output characteristics of small-scale (l≤30 cm, d≤1.1cm) gas-discharge recombination He—Sr+ (λ=430.5 nm) and He— Ca+ (λ=373.7nm) lasers is provided. Such compact lasers are characterised by a relatively high reliability and durability. These lasers are easy to operate and are capable of generating laser pulses with high repetition rates f, a high specific mean power Psp, and an improved quality of output radiation. A typical mean power P of self-heating sealed-off He—Sr+ (Ca+) laser tubes with l≈ 30 cm and d≈ 1 cm is ~ 0.5 W. The best specific characteristics of a He—Sr+ laser with tubes of this type were achieved with l=20 cm and d=0.6 cm (Psp=73 mW cm-3) and l=9 cm and d=0.55 cm (Psp=65 W cm-3). The best specific characteristics for a He—Ca+ laser were achieved with l=26.5 cm and d=0.7 cm (Psp=50 mW cm-3). The use of forced water cooling in a He—Sr+(Ca+) laser allowed the powers P=3.9 W and Psp=137 mW cm-3 to be achieved with a tube with l=30 cm and d=1.1 cm for f=29 kHz. A new method of inputting metal vapours based on cataphoresis is considered in detail. Using this method allowed the output characteristics of a He—Sr+ laser to be considerably improved and a record specific power Psp=277 mW cm-3 to be achieved for a tube with l=26 cm and d=0.3 cm with f=30 kHz and P=510 mW. A record gain, 0.15 cm-1, was also achieved under these conditions. Some possible areas of applications of small-scale He—Sr+(Ca+) lasers in semiconductor microtechnology, holography, ecology, and medicine are outlined.
Optical properties of Bragg fibres

The electrodynamic problem of propagation of light in a fibre with a cladding made of coaxial dielectric layers with alternating values of the refractive index is solved. The fibre core is a dielectric, in particular, air with the lowest permittivity in the fibre structure. A method is described for determining the structure of the multilayer cladding of a fibre having the minimal optical loss of the guided radiation for a particular mode. Losses in a fibre with a cladding with quasi-periodic layer thicknesses are calculated and the dispersion properties of the fibre are analysed. The analysis is performed for the lowest TE and TM modes and for the lowest hybrid mode.
A novel mixed-synchronization phenomenon in coupled Chua's circuits via non-fragile linear control

Dynamical variables of coupled nonlinear oscillators can exhibit different synchronization patterns depending on the designed coupling scheme. In this paper, a non-fragile linear feedback control strategy with multiplicative controller gain uncertainties is proposed for realizing the mixed-synchronization of Chua's circuits connected in a drive-response configuration. In particular, in the mixed-synchronization regime, different state variables of the response system can evolve into complete synchronization, anti-synchronization and even amplitude death simultaneously with the drive variables for an appropriate choice of scaling matrix. Using Lyapunov stability theory, we derive some sufficient criteria for achieving global mixed-synchronization. It is shown that the desired non-fragile state feedback controller can be constructed by solving a set of linear matrix inequalities (LMIs). Numerical simulations are also provided to demonstrate the effectiveness of the proposed control approach.
Group theoretical and topological analysis of the quantum spin Hall effect in silicene

Silicene consists of a monolayer of silicon atoms in a buckled honeycomb structure. It was recently discovered that the symmetry of such a system allows for interesting Rashba spin–orbit effects. A perpendicular electric field is able to couple to the sublattice pseudospin, making it possible to electrically tune and close the band gap. Therefore, external electric fields may generate a topological phase transition from a topological insulator to a normal insulator (or semimetal) and vice versa. The contribution of the present paper to the study of silicene is twofold. Firstly, we perform a group theoretical analysis to systematically construct the Hamiltonian in the vicinity of the K points of the Brillouin zone and find an additional, electric field induced spin–orbit term, that is allowed by symmetry. Subsequently, we identify a tight-binding model that corresponds to the group theoretically derived Hamiltonian near the K points. Secondly, we start from this tight-binding model to analyze the topological phase diagram of silicene by an explicit calculation of the Z2? > topological invariant of the band structure. To this end, we calculate the Z2? > topological invariant of the honeycomb lattice in a manifestly gauge invariant way which allows us to include Sz symmetry breaking terms—like Rashba spin–orbit interaction—into the topological analysis. Interestingly, we find that the interplay of a Rashba and an intrinsic spin–orbit term can generate a non-trivial quantum spin Hall phase in silicene. This is in sharp contrast to the more extensively studied honeycomb system graphene where Rashba spin–orbit interaction is known to compete with the quantum spin Hall effect in a detrimental way.
Change in the static rheological properties of the aorta in Kurosawa and Kusanagi-Hypercholesterolemic (KHC) rabbits with progress of atherosclerosis

The rheological properties of the arterial wall have intimate connections with the fine structure of the wall. Alteration in fine structure due to cardiovascular disease, such as atherosclerosis, could affect the rheological characteristics of the wall. The present study was designed to investigate changes in the static rheological properties of the aorta in Kurosawa and Kusanagi-Hypercholesterolemic (KHC) rabbits aged 10–12, 22–24 and 34–36 months in relation to histological alteration of the wall due to progression of atherosclerosis with age. Circumferential wall strips were excised from the ascending, proximal descending thoracic and proximal abdominal aortas and their stress/strain relationship was recorded. Tensile force of the wall showed a slight but insignificant decrease in the KHC rabbit group aged 10–12 months compared to that in the age-matched control group in the proximal thoracic aorta and increased significantly with ageing in the KHC rabbits in these aortic regions mainly at medium and high strain ranges. Wall stress was significantly smaller in the 10–12 months old KHC rabbit group than in the age-matched control group in the proximal thoracic and proximal abdominal aortas and increased significantly with ageing in the KHC rabbit groups chiefly at medium and high strain ranges. Incremental elastic modulus determined at 50% stretching of the initial length of the wall strip was also significantly lower in the KHC rabbit group aged 10–12 months in comparison to that in the age-matched control group and increased significantly with ageing in the KHC rabbit group. The intima thickened severely with abundant foam cells in the KHC rabbits aged 10–12 months. With increasing age, collagen and elastin fibres showed signs of gradual proliferation among the foam cells. The aortic wall in KHC rabbits was viscoelastic in the relatively early stage of atherosclerosis due to abundant foam cells, and thereafter increased in stiffness gradually with fibrous proliferation and calcification. We can conclude that the static rheological properties of the atherosclerotic aortic wall changed in association with alteration in the microstructure of the wall with progression of atherosclerosis.
The Influence Mechanism of Class Identification and Environmental Values on Garbage Classification Behavior

Empirical Analysis Based on the Data of the 2015 Urban Residents Living Conditions Survey; The mediating effect model of perceived behavioral control and perceived behavioral dynamics is tested to explore the internal mechanism of public garbage classification behavior. Through the analysis of mediating effect model, we find that the class identity has direct effect on garbage classification behavior, and the mediating effect is reflected by perceived behavior control and perceived behavior dynamics. Environmental values have direct effects on garbage classification behavior and have significant mediating effects through environmental behavior control. Therefore, promoting the public green consumption idea, fostering the environment-saving habits, can enhance environmental responsibility awareness, promote the public garbage classification behavior.
International comparison CCQM-P41 Greenhouse gases. 1. Measurement capability

The measurement of greenhouse gases in the atmosphere is one of the activities to monitor changes in the global environment, as some of these gases are presumed to contribute to climate change. The CCQM Gas Analysis Working Group has organised a pilot comparison for carbon dioxide and methane at ambient levels to compare primarily the capabilities of national metrology institutes (NMIs) for measuring these species in air. The participation in this comparison was not limited to signatories of the MRA, as is usually the case. Laboratories from the World Meteorological Organisation (WMO) were invited as well, and two participated. The project has been split in two parts, a comparison of the (analytical) measurement capability, and a high-accuracy comparison of primary standard gas mixtures for greenhouse gases. In this first part, the measurement capability was compared between NMIs and WMO laboratories. The nominal amount-of-substance fraction levels are 365 µmol/mol for carbon dioxide and 1.8 µmol/mol for methane. The matrix was synthetic air, simulated by a mixture of nitrogen, oxygen (209 mmol/mol) and argon (9.3 mmol/mol). The measurements took place in the spring of 2003. The protocol used for this comparison was the same as used so far in the gas analysis area for key comparisons and studies of this type. The reference values were assigned to each gas mixture on the basis of the gravimetric preparation, taking into account the results from the purity verification. In particular for the value assignment of methane, traces of methane in the matrix gases (nitrogen, oxygen and argon) can influence the value assigned to the gas mixture appreciably. The results for methane agree within 4% relative, and for most participants even within 2% relative at an amount of substance fraction level of 1.8 µmol/mol. For carbon dioxide all results agree within 1% relative, and for most the agreement is even better: within 0.5% relative at an amount of substance fraction level of 365 µmol/mol. The methane data show a discrepancy of approximately 0.025 µmol/mol between the averages of the WMO laboratories and the NMIs, which confirms results of earlier comparisons. Measurement traceability is quite differently established in NMIs and WMO laboratories, and may account for this difference. Further work is needed to find out the causes of this difference.

The Integrative Action of the Autonomic Nervous System

Almost all bodily functions are dependent on activity of the autonomic nervous system – from the cardiovascular system, the gastrointestinal tract, the evacuative and sexual organs, to the regulation of temperature, metabolism and tissue defence. Balanced functioning of each aspect of this system is an important basis of our life and well-being. In this long-awaited second edition, the author, a leading figure in this field, provides an up-to-date and detailed description of the cellular and integrative organization of the autonomic nervous system, covering both peripheral and central aspects. The book exposes modern neurobiological concepts that allow us to understand why this system normally runs so smoothly and why its deterioration has such disastrous consequences. This broad overview will appeal to researchers and advanced undergraduate students of the various biological and medical sciences studying how the autonomic nervous system works and to clinicians and physical therapists whose practice involves systems dependent on autonomic functions.
Ultrasound-Guided Regional Anesthesia

An ultrasound wave is produced when an electrical signal is placed across piezoelectric crystals that force the crystals to vibrate. This vibration is then conducted through the body. All ultrasound waves are characterized by a specific wavelength and frequency. The relationship between these variables is c is proportional to (λ)*(f), where c = the propagation velocity and is presumed to be 1540 m/sec in the human body. Therefore, if c is held constant, then to increase the frequency of an ultrasound wave, the wavelength would have to proportionately decrease. This concept is at the core of UGRA since different frequency probes are used for different blocks.
Magnetic resonance imaging of radiation dose distributions using a polymer-gel dosimeter

A new formulation of a tissue-equivalent polymer-gel dosimeter for the measurement of three-dimensional dose distributions of ionizing radiation has been developed. It is composed of aqueous gelatin infused with acrylamide and N, N'-methylene-bisacrylamide monomers, and made hypoxic by nitrogen saturation. Irradiation of the gel, referred to as BANG, causes localized polymerization of the monomers, which, in turn, reduces the transverse NMR relaxation times of water protons. The dose dependence of the NMR transverse relaxation rate, R2, is reproducible (less than 2% variation) and is linear up to about 8 Gy, with a slope of 0.25 s-1Gy-1 at 1.5 T. Magnetic resonance imaging may be used to obtain accurate three-dimensional dose distributions with high spatial resolution. Since the radiation-induced polymers do not diffuse through the gelatin matrix, the dose distributions recorded by BANG gels are stable for long periods of time, and may be used to measure low-activity radioactive sources. Since the light-scattering properties of the polymerized regions are different from those of the clear, non-irradiated regions, the dose distributions are visible, and their optical densities are dependent on dose.
Recent tests of the mode-coupling theory for glassy dynamics

An overview is given of recent tests of the mode-coupling theory for the evolution of structural relaxation in glass-forming liquids. Emphasis is put on comparisons between the leading-order asymptotic formulae derived for the dynamics near glass transition singularities and the results of neutron scattering, depolarized light scattering, impulsive stimulated light scattering and dielectric-loss spectroscopy for conventional liquids. The tests based on photon-correlation spectroscopy results for the glassy dynamics of colloids and the findings of molecular dynamics simulations for model systems are also considered.

Design of a smart functionally graded thermopiezoelectric composite structure

In this paper, a smart functionally graded piezoelectric structure is analyzed. The smart structure consists of three layers: one layer of metal, one layer of piezoelectric material (PZT) used as an actuator, and a graded metal/PZT layer between the metal layer and the PZT layer. A finite element code is developed in the programming environment MATLAB and FORTRAN, with each finite element having varied material properties through space coordinates. The results reveal that both the stress discontinuity and thermal deformation of the structure can be controlled. By introducing a functionally graded layer between the PZT actuator layer and the metal beam layer, both stress discontinuity and the edge local stresses can be essentially reduced. The proposed method is expected to be useful for functionally graded thermopiezoelectric composite structures under operating environments where the thermal and piezoelectic effects are important.
