description: This paper proposes a novel scheme, based on progressive fountain codes, for broadcasting JPEG 2000 multimedia. In such a broadcast scheme, progressive resolution levels of images/video have been unequally protected when transmitted using the proposed progressive fountain codes. With progressive fountain codes applied in the broadcast scheme, the resolutions of images (JPEG 2000) or videos (MJPEG 2000) received by different users can be automatically adaptive to their channel qualities, i.e. the users with good channel qualities are possible to receive the high resolution images/vedio while the users with bad channel qualities may receive low resolution images/vedio. Finally, the performance of the proposed scheme is evaluated with the MJPEG 2000 broadcast prototype.

description: The European target to drastically reduce the CO2 emissions by 2050 could create new major transmission needs in Europe; their identification is one of the main objectives of the e-highway2050 project. In deliverables D1.2 and D2.1 of the project, five scenarios of generation, demand and storage were defined to encompass a wide range of possibilities to reach the CO2 reduction target in 2050. D2.3 aimed at identifying the required grid architecture for each one of these five scenarios. That is to say the additional transmission corridors (including their target capacities) to be developed on top of a starting grid. These architectures are allocated a cost and a benefit following a methodology explained in depth in the document. D2.4 focused on the operational validation of the inter-cluster reinforcements.

description: We study the electronic structure of two types of transition metal complexes, the inverted-sandwich-type and open-lantern-type, by the electronic stress tensor. In particular, the bond order b_e measured by the energy density which is defined from the electronic stress tensor is studied and compared with the conventional MO based bond order. We also examine the patterns found in the largest eigenvalue of the stress tensor and corresponding eigenvector field, the "spindle structure" and "pseudo-spindle structure". As for the inverted-sandwich-type complex, our bond order b_e calculation shows that relative strength of the metal-benzene bond among V, Cr and Mn complexes is V > Cr > Mn which is consistent with the MO based bond order. As for the open-lantern-type complex, we find that our energy density based bond order can properly describe the relative strength of Cr--Cr and Mo--Mo bonds by the surface integration of the energy density over the "Lagrange surface" which can take into account the spatial extent of the orbitals.

description: The quadrupole moments of odd neighbors of semi-magic lead and tin isotopes and $N=50,N=82$ isotones are calculated within the self-consistent Theory of Finite Fermi Systems based on the Energy Density Functional by Fayans et al. Two sets of parameters, DF3 and DF3-a, fixed previously are used. They differ by the spin-orbit and effective tensor force parameters, the latter being significantly bigger in the DF3-a functional. Results for the two functionals turned out to be rather different. The functional DF3-a leads to quadrupole moments in reasonable agreement with the experimental ones for most nuclei examined.

description: A proposal for an all-optical memory based on a bistability of single-mode states in a dual-mode diode laser with time-delayed optical feedback is presented. The system is modeled using a multimode extension of the Lang-Kobayashi equations with injected optical pulses. We uncover the bifurcation structure by deriving analytical expressions for the boundaries of the bistable region and demonstrate how the delay time in the external cavity determines an optimal pulse duration for efficient switching of the memory element. We also show the relevant role played by gain saturation and by the dual-mode solutions of the Lang-Kobayashi equations for the existence of the bistable regions. Our results demonstrate that feedback induced bistability can lead to significant performance improvements when compared to memory elements based on the injection locking bistability in dual-mode devices.

description: The purpose of the work described in this dissertation was to investigate erythropoietin (Epo) production as a physiological response to intense exercise. Prior to examining changes in Epo secretion, the analytical performance of a radioimmunoassay was evaluated. Sample preparation was controlled to improve precision and sensitivity at lower values, increasing the resolution of alterations in Epo synthesis. A normal reference range for 1 000m elevation was established from 175 males in 11 different age groups, 20 females, and 14 elite athletes. No significant differences in Epo were observed with age, sex, menstrual phase or athletic status. Increased Epo synthesis and reticulocytosis were observed in athletes, within 10 days training at 2100-2225m. Intrinsic variance in Epo production over 24 h was monitored in 26 males, no circadian pattern was detected. Hypoxemia was evaluated using reflective probe pulse oximetry, validated against oxyhemoglobin saturation (SaO2) determined by CO-oximetry. Eight volunteers exercised for 3 min at supramaximal intensities with an indwelling arterial catheter. The limits of agreement for the two methods were good (-3.9 to 3.7%), however, calculated bias increased with greater levels of hypoxemia (SaO2>92% = - 0.6±1.8; SaO2≤86% = 2.3±3.1). Serum Epo concentrations were increased following exercise in subjects who desaturated (23±12%), but remained unchanged in subjects with normal saturation levels. Continuous supramaximal exercise performed by 11 athletes produced greater increases in Epo (35±16%) than an intermittent protocol (27±4%), but was less effective in inducing hypoxemia (44±22s and 68±34s respectively). In contrast, exercise at 21 00m resulted in increased magnitude and duration of hypoxemia compared to 1000m in 5 athletes, and a relationship between duration of hypoxemic episode and increase in Epo levels was observed (F₍₅,₄₎)=16.93; r=0.94; MSE=10.67). Plasmapheresis resulted in increased serum Epo levels in 7 volunteers at rest (24±6%), suggesting a role for plasma volume replenishment in induction of Epo synthesis. These experiments have demonstrated that the production of endogenous Epo can be induced by intense exercise, increasing the severity of hypoxemia through altitude exposure can exacerbate this response. The plasmapheresis experiment leads to the hypothesis that alterations in plasma volume may contribute to the sensitivity of Epo production to exercise induced hypoxemia.
Coarse Variables of Autonomous ODE Systems and Their Evolution

description: Given an autonomous system of ordinary differential equations (ODE), we consider developing practical models for the deterministic, slow/coarse behavior of the ODE system. Two types of coarse variables are considered. The first type consists of running finite time averages of phase functions. Approaches to construct the coarse evolution equation for this type are discussed and implemented on a 'Forced' Lorenz system and a singularly perturbed system whose fast flow does not necessarily converge to an equilibrium. We explore two strategies. In one, we compute (locally) invariant manifolds of the fast dynamics, parameterized by the slow variables. In the other, the choice of our coarse variables automatically guarantees them to be 'slow' in a precise sense. This allows their evolution to be phrased in terms of averaging utilizing limit measures (probability distributions) of the fast flow. Coarse evolution equations are constructed based on these approaches and tested against coarse response of the 'microscopic' models. The second type of coarse variables are defined as (non-trivial) scalar state functions that are required by design to evolve autonomously, to the extent possible, with the goal of being candidate state functions for unambiguously initializable coarse dynamics. The question motivates a mathematical restatement in terms of a first-order PDE. A computational approximation is developed and tested on the Lorenz system and the Hald Hamiltonian system.

description: The evolution of electronic structure of graphene nanoribbons (GNRs) as a function of the number of layers stacked together is investigated using \textit{ab initio} density functional theory (DFT) including interlayer van der Waals interactions. Multilayer armchair GNRs (AGNRs), similar to single-layer AGNRs, exhibit three classes of band gaps depending on their width. In zigzag GNRs (ZGNRs), the geometry relaxation resulting from interlayer interactions plays a crucial role in determining the magnetic polarization and the band structure. The antiferromagnetic (AF) interlayer coupling is more stable compared to the ferromagnetic (FM) interlayer coupling. ZGNRs with the AF in-layer and AF interlayer coupling have a finite band gap while ZGNRs with the FM in-layer and AF interlayer coupling do not have a band gap. The ground state of the bi-layer ZGNR is non-magnetic with a small but finite band gap. The magnetic ordering is less stable in multilayer ZGNRs compared to single-layer ZGNRs. The quasipartcle GW corrections are smaller for bilayer GNRs compared to single-layer GNRs because of the reduced Coulomb effects in bilayer GNRs compared to single-layer GNRs.

description: This article provides a description and an attempt to contextualise representations of head and pectoral protection depicted on the statue menhirs of Corsica. These monuments are among the most representative of Corsica’s Bronze Age and hold a decisive importance in historiography. Unfortunately, no actual armour – may it be organic or made from metal – is known today from Corsica. We aim to describe and interpret the represented armour as it is seen on the menhirs and compare it with neighbouring regions such as Sardinia, from where plenty of armour depictions are known both from bronze figurines and stone stelae, but also with finds and depictions of other armour from the Mediterranean, in order to reconstruct the genesis and evolution of these armour types.

description: We investigate the surface nitrogen content of the six magnetic O stars known to date as well as of the early B-type star tau Sco. We compare these abundances to predictions of evolutionary models to isolate the effects of magnetic field on the transport of elements in stellar interiors. We conduct a quantitative spectroscopic analysis of the sample stars with state-of-the-art atmosphere models. We rely on high signal-to-noise ratio, high resolution optical spectra obtained with ESPADONS at CFHT and NARVAL at TBL. Atmosphere models and synthetic spectra are computed with the code CMFGEN. Values of N/H together with their uncertainties are determined and compared to predictions of evolutionary models. We find that the magnetic stars can be divided into two groups: one with stars displaying no N enrichment (one object); and one with stars most likely showing extra N enrichment (5 objects). For one star (Theta1 Ori C) no robust conclusion can be drawn due to its young age. The star with no N enrichment is the one with the weakest magnetic field, possibly of dynamo origin. It might be a star having experienced strong magnetic braking under the condition of solid body rotation, but its rotational velocity is still relatively large. The five stars with high N content were probably slow rotators on the zero age main sequence, but they have surface N/H typical of normal O stars, indicating that the presence of a (probably fossil) magnetic field leads to extra enrichment. These stars may have a strong differential rotation inducing shear mixing. Our results should be viewed as a basis on which new theoretical simulations can rely to better understand the effect of magnetism on the evolution of massive stars.

description: Nucleic acid aptamers as antibody alternatives bind specifically to target molecules. These aptamers are generated by isolating candidates from libraries with random sequence fragments, through an evolutionary engineering system. We recently reported a high-affinity DNA aptamer generation method that introduces unnatural bases (UBs) as a fifth letter into the library, by genetic alphabet expansion. By incorporating hydrophobic UBs, the affinities of DNA aptamers to target proteins are increased over 100-fold, as compared with those of conventional aptamers with only the natural four letters. However, there is still plenty of room for improvement of the methods for routinely generating high-affinity UB-containing DNA (UB-DNA) aptamers. The success probabilities of the high-affinity aptamer generation depend on the existence of the aptamer candidate sequences in the initial library. We estimated the success probabilities by analysing several UB-DNA aptamers that we generated, as examples. In addition, we investigated the possible improvement of conventional aptamer affinities by introducing one UB at specific positions. Our data revealed that UB-DNA aptamers adopt specific tertiary structures, in which many bases including UBs interact with target proteins for high affinity, suggesting the importance of the UB-DNA library design.This article is part of the theme issue ‘Reactivity and mechanism in chemical and synthetic biology’.

description: Optical spectrometers, instruments that work with monochromatic light, are commonly rated by the spectral bandwidth, which defines the ability to resolve closely spaced spectral components. The ability to detect faint objects among these components, spectral contrast, is another desired aspect. Here we demonstrate that a combined effect of angular dispersion (AD) and anomalous transmission (AT) of x rays in Bragg reflection from asymmetrically cut crystals can shape spectral distributions of x rays to profiles with record high contrast and small bandwidths. The AD&AT x-ray optics is implemented as a five-reflection three-crystal arrangement featuring a combination of the above mentioned attributes, so much desirable for x-ray monochromators and analyzers: a spectral contrast of ~ 500, a bandwidth of ~ 0.46 meV and a remarkably large angular acceptance of ~ 107 urad. The new optics can become a foundation for the next generation inelastic x-ray scattering spectrometers for studies of atomic dynamics.

description: We calculate the low energy constants of four-nucleon interactions in an effective chiral Lagrangian in holographic QCD. We start with a D4-D8 model to obtain meson-nucleon interactions and then integrate out massive mesons to obtain the four-nucleon interactions in 4D. We end up with two low energy constants at the leading order and seven of them at the next leading order, which is consistent with the effective chiral Lagrangian. The values of the low energy constants are evaluated with the first five Kaluza-Klein resonances.

Also, a generalization of a known result to the case of any set of initial data is stated and proved. In terms of applica­tions, known subdivision schemes and a new one together with graphical examples are discussed in view of properties such as interpolatory, polynomial preserving and the smoothness class of the limit function.

description: In spite of many observational efforts aiming to characterize the chemical evolution of our Galaxy, not much is known about the origin of fluorine (F). Models suggest that the F found in the Galaxy might have been produced mainly in three different ways, namely, Type II supernovae, asymptotic giant branch nucleosynthesis, or in the core of Wolf-Rayet stars. Only a few observational measurements of F abundances are available in the literature and mostly for objects whose characteristics might hamper an accurate determination of fluorine abundance (e.g.,complex mixing and nucleosynthesis processes, external/internal contamination). We derive the F abundances for a set of nine cool main-sequence dwarfs in the solar neighbourhood, based on an unblended line of the HF molecule at 2.3 microns. In addition, we study the s-process elements of five of these stars. We acquire data using the high-resolution IR-spectrograph CRIRES and gather FEROS data from the European Southern Observatory archive. Several of the analysed stars seem to be slightly fluorine enhanced with respect to the Sun, although no correlation is found between the F abundance and the iron content. In addition, the most fluorine enriched stars are also yttrium and zirconium enriched, which suggests that AGB fluorine nucleosynthesis is the dominant source of fluorine production for the observed stars. Nevertheless, the correlation between [F/Fe] and the s-elements is rather weak and possibly masked by the uncertainties in the F abundance measurements. Finally, we compare our derived F abundances to previous measurements of alpha-element and iron-peak element abundances. Type II core collapse Supernovae do not appear to be the main site of F production for our targets, as no correlation seems to exist between the [F/Fe] and the [alpha/Fe] ratios.

description: The primary purpose of this document is to provide local and federal partners with baseline information and survey methods to allow for continued monitoring efforts to evaluate the effectiveness of management actions taken at the Samoa Maritime quarry in Faga'alu, American Samoa. This document summarizes work completed between 2012 and 2014, and was coordinated and funded by the National Oceanic and Atmospheric Administration (NOAA) Coral Reef Conservation Program (CRCP) to gather baseline data and information before management interventions such as drainage systems, alternative ground cover, and retention ponds were installed at the quarry to reduce land-based sources of pollution inputs to the coral reefs in Fagaʻalu Bay. The work was funded through direct investments made by the NOAA CRCP, through a Cooperative Agreement with American Samoa to the Coral Reef Advisory Group (CRAG), and through a domestic grant awarded to San Diego State University (SDSU) titled, 'Monitoring and analysis of sediment accumulation and composition on coral reefs in Faga'alu Bay, American Samoa' which extended previous efforts supported by the Department of Interior – Insular Affairs Office through the CRAG. To carry out these baseline assessments, technical and scientific experts from NOAA and SDSU collaborated to gather baseline information to share with local management authorities in American Samoa. These 2012-2014 activities describe the pre-intervention baseline data collection, analysis, and interpretation needed to evaluate the effectiveness of subsequently planned interventions over time. To quantify effectiveness of these interventions, additional long-term monitoring of sediment loads in Faga'alu Stream and coral community structure will be needed for comparison with the baselines presented here. The overall effort required to evaluate the effectiveness of the interventions is large, and requires a close coordination between local and federal efforts.

description: This paper considers the problem of robust stability for a class of uncertain quantum systems subject to unknown perturbations in the system Hamiltonian. Some general stability results are given for different classes of perturbations to the system Hamiltonian. Then, the special case of a nominal linear quantum system is considered with either quadratic or non-quadratic perturbations to the system Hamiltonian. In this case, robust stability conditions are given in terms of strict bounded real conditions.

description: Complex Orthogonal Design (COD) codes are known to have the lowest detection complexity among Space-Time Block Codes (STBCs). However, the rate of square COD codes decreases exponentially with the number of transmit antennas. The Quasi-Orthogonal Design (QOD) codes emerged to provide a compromise between rate and complexity as they offer higher rates compared to COD codes at the expense of an increase of decoding complexity through partially relaxing the orthogonality conditions. The QOD codes were then generalized with the so called g-symbol and g-group decodable STBCs where the number of orthogonal groups of symbols is no longer restricted to two as in the QOD case. However, the adopted approach for the construction of such codes is based on sufficient but not necessary conditions which may limit the achievable rates for any number of orthogonal groups. In this paper, we limit ourselves to the case of Unitary Weight (UW)-g-group decodable STBCs for 2^a transmit antennas where the weight matrices are required to be single thread matrices with non-zero entries in {1,-1,j,-j} and address the problem of finding the highest achievable rate for any number of orthogonal groups. This special type of weight matrices guarantees full symbol-wise diversity and subsumes a wide range of existing codes in the literature. We show that in this case an exhaustive search can be applied to find the maximum achievable rates for UW-g-group decodable STBCs with g>1. For this purpose, we extend our previously proposed approach for constructing UW-2-group decodable STBCs based on necessary and sufficient conditions to the case of UW-g-group decodable STBCs in a recursive manner.

description: Electrostatic waves in a collision-free unmagnetized plasma of electrons with fixed ions are investigated for electron equilibrium velocity distribution functions that deviate slightly from Maxwellian. Of interest are undamped waves that are the small amplitude limit of nonlinear excitations, such as electron acoustic waves (EAWs). A deviation consisting of a small plateau, a region with zero velocity derivative over a width that is a very small fraction of the electron thermal speed, is shown to give rise to new undamped modes, which here are named {\it corner modes}. The presence of the plateau turns off Landau damping and allows oscillations with phase speeds within the plateau. These undamped waves are obtained in a wide region of the $(k,ω_{_R})$ plane ($ω_{_R}$ being the real part of the wave frequency and $k$ the wavenumber), away from the well-known `thumb curve' for Langmuir waves and EAWs based on the Maxwellian. Results of nonlinear Vlasov-Poisson simulations that corroborate the existence of these modes are described. It is also shown that deviations caused by fattening the tail of the distribution shift roots off of the thumb curve toward lower $k$-values and chopping the tail shifts them toward higher $k$-values. In addition, a rule of thumb is obtained for assessing how the existence of a plateau shifts roots off of the thumb curve. Suggestions are made for interpreting experimental observations of electrostatic waves, such as recent ones in nonneutral plasmas.

description: Co-management has been loosely defined as a transfer of decision-making authority to non-traditional actors in the process of natural resource management. Most co-management agreements have been developed in the context of land claim agreements in the Territories. Co-management has not been utilized to any great extent in the provinces. This can be traced to a lack of clarification of rights held by First Nations to land and resources off-reserve. Nevertheless, co-management terminology and theory are increasingly being cited outside of land claims, within a provincial resource management context. Co-management is not possible under present circumstances within the provinces. Without a drastic change in the relationship between First Nations and the provincial and federal governments, co-management is simply an empty promise. In the absence of equal rights of participation gained through rights to land off-reserve, co-management cannot be realized.
Transport through graphene on SrTiO3

description: We report transport measurements through graphene on SrTiO3 substrates as a function of magnetic field B, carrier density n, and temperature T. The large dielectric constant of SrTiO3 screens very effectively long-range electron-electron interactions and potential fluctuations, making Dirac electrons in graphene virtually non-interacting. The absence of interactions results in a unexpected behavior of the longitudinal resistance in the N=0 Landau level, and in a large suppression of the transport gap in nano-ribbons. The "bulk" transport properties of graphene at B=0T, on the contrary, are completely unaffected by the substrate dielectric constant.

Note on the role of symmetry in scattering from isospectral graphs and drums

description: We discuss scattering from pairs of isospectral quantum graphs constructed using the method described in [1, 2]. It was shown in [3] that scattering matrices of such graphs have the same spectrum and polar structure, provided that infinite leads are attached in a way which preserves the symmetry of isospectral construction. In the current paper we compare this result with the conjecture put forward by Okada et al. [4] that the pole distribution of scattering matrices in the exterior of isospectral domains in R^2 are different.
A Perfect Model for Bounded Verification

description: A class of languages C is perfect if it is closed under Boolean operations and the emptiness problem is decidable. Perfect language classes are the basis for the automata-theoretic approach to model checking: a system is correct if the language generated by the system is disjoint from the language of bad traces. Regular languages are perfect, but because the disjointness problem for CFLs is undecidable, no class containing the CFLs can be perfect. In practice, verification problems for language classes that are not perfect are often under-approximated by checking if the property holds for all behaviors of the system belonging to a fixed subset. A general way to specify a subset of behaviors is by using bounded languages (languages of the form w1* ... wk* for fixed words w1,...,wk). A class of languages C is perfect modulo bounded languages if it is closed under Boolean operations relative to every bounded language, and if the emptiness problem is decidable relative to every bounded language. We consider finding perfect classes of languages modulo bounded languages. We show that the class of languages accepted by multi-head pushdown automata are perfect modulo bounded languages, and characterize the complexities of decision problems. We also show that bounded languages form a maximal class for which perfection is obtained. We show that computations of several known models of systems, such as recursive multi-threaded programs, recursive counter machines, and communicating finite-state machines can be encoded as multi-head pushdown automata, giving uniform and optimal underapproximation algorithms modulo bounded languages.
