Biexponential decay and ultralong coherence of a qubit

A quantum two-state system, weakly coupled to a heat bath, is traditionally studied in the Born-Markov regime under the secular approximation with completely positive linear master equations. Despite its success, this microscopic approach exclusively predicts exponential decays and Lorentzian susceptibility profiles, in disagreement with a number of experimental findings. On the contrary, in the absence of the secular approximation they can be explained but with the risk of jeopardizing the positivity of the density matrix. To avoid these drawbacks, we use a physically motivated nonlinear master equation being both thermodynamically and statistically consistent. We find that, beyond a temperature-dependent threshold, a bifurcation in the decoherence time T2 takes place; it gives rise to a biexponential decay and a susceptibility profile being neither Gaussian nor Lorentzian. This implies that, for suitable initial states, a major prolongation of the coherence can be obtained in agreement with recent experiments. Moreover, T2 is no longer limited by the energy relaxation time T1 offering novel perspectives to elaborate devices for quantum information processing.

Afterwards, we assemble a quite number of classification method that being implemented for activity recognition in past few years.
Genome-centric metagenomics revealed the spatial distribution and the diverse metabolic functions of lignocellulose degrading uncultured bacteria

The mechanisms by which specific anaerobic microorganisms remain firmly attached to lignocellulosic material allowing them to efficiently decompose the organic matter are far to be elucidated. To circumvent this issue, the microbiomes collected from anaerobic digesters treating pig manure and meadow grass were fractionated to separate the planktonic microbes from those adhered to lignocellulosic substrate. Assembly of shotgun reads followed by binning process recovered 151 population genomes, 80 out of which were completely new and were not previously deposited in any database. Genome coverage allowed the identification of microbial spatial distribution into the engineered ecosystem. Moreover, a composite bioinformatic analysis using multiple databases for functional annotation revealed that uncultured members of Bacteroidetes and Firmicutes follow diverse metabolic strategies for polysaccharide degradation. The structure of cellulosome in Firmicutes can vary depending on the number and functional roles of carbohydrate-binding modules. On contrary, members of Bacteroidetes are able to adhere and degrade lignocellulose due to the presence of multiple carbohydrate-binding family 6 modules in beta-xylosidase and endoglucanase proteins or S-layer homology modules in unknown proteins. This study combines the concept of variability in spatial distribution with genome-centric metagenomics allowing a functional and taxonomical exploration of the biogas microbiome. Importance This work contributes new knowledge about lignocellulose degradation in engineered ecosystems. Specifically, the combination of the spatial distribution of uncultured microbes with genome-centric metagenomics provides novel insights into the metabolic properties of planktonic and firmly attached to plant biomass bacteria. Moreover, the knowledge obtained in this study enabled us to understand the diverse metabolic strategies for polysaccharide degradation in different species of Bacteroidetes and Clostridiales. Even though structural elements of cellulosome were restricted to Clostridiales, our study identified in Bacteroidetes a putative mechanism for biomass decomposition based on a gene cluster responsible for cellulose degradation, disaccharide cleavage to glucose and transport to cytoplasm.
Signal Processing in Telecommunications with Forward Correction of Errors

The development of mechanisms of increase efficiency of frequency-shift keying signals processing in telecommunications using algorithms of noise immunity channel coding in obstacle effect conditions is held in the article. The synthesis of the frequency-shift keying signal processing unit accounting intersymbol communication which is inherent for such signals with continuous phase is held. The conditions of the compromise implementation in the telecommunication information transmission channel with frequency shift keying and error correction coding for setting the optimal encoding rate in the range of the bandwidth of the information transmission system are explored. Linear cyclic codes Bose-Chaudhuri-Hocquenghem (BCH) are used for studying. By means of Matlab the article focuses on the definition of energetic benefit compared to uncoded system in case of equality of the bandwidth of the information transmission system with coding and without coding.
Assessment of the Safety and Immunogenicity of 2 Novel Vaccine Platforms for HIV-1 Prevention: A Randomized Trial.

BACKGROUND A prophylactic HIV-1 vaccine is a global health priority. OBJECTIVE To assess a novel vaccine platform as a prophylactic HIV-1 regimen. DESIGN Randomized, double-blind, placebo-controlled trial. Both participants and study personnel were blinded to treatment allocation. (ClinicalTrials.gov: NCT01215149). SETTING United States, East Africa, and South Africa. PATIENTS Healthy adults without HIV infection. INTERVENTION 2 HIV-1 vaccines (adenovirus serotype 26 with an HIV-1 envelope A insert [Ad26.EnvA] and adenovirus serotype 35 with an HIV-1 envelope A insert [Ad35.Env], both administered at a dose of 5 × 1010 viral particles) in homologous and heterologous combinations. MEASUREMENTS Safety and immunogenicity and the effect of baseline vector immunity. RESULTS 217 participants received at least 1 vaccination, and 210 (>96%) completed follow-up. No vaccine-associated serious adverse events occurred. All regimens were generally well-tolerated. All regimens elicited humoral and cellular immune responses in nearly all participants. Preexisting Ad26- or Ad35-neutralizing antibody titers had no effect on vaccine safety and little effect on immunogenicity. In both homologous and heterologous regimens, the second vaccination significantly increased EnvA antibody titers (approximately 20-fold from the median enzyme-linked immunosorbent assay titers of 30-300 to 3000). The heterologous regimen of Ad26-Ad35 elicited significantly higher EnvA antibody titers than Ad35-Ad26. T-cell responses were modest and lower in East Africa than in South Africa and the United States. LIMITATIONS Because the 2 envelope inserts were not identical, the boosting responses were complex to interpret. Durability of the immune responses elicited beyond 1 year is unknown. CONCLUSION Both vaccines elicited significant immune responses in all populations. Baseline vector immunity did not significantly affect responses. Second vaccinations in all regimens significantly boosted EnvA antibody titers, although vaccine order in the heterologous regimen had a modest effect on the immune response.

A Posterior Predictive Approach to Multiple Response Surface Optimization

In this paper we present an approach to multiple response surface optimization that not only provides optimal operating conditions, but also measures the reliability of an acceptable quality result for any set of operating conditions. The most utilized multiple response optimization approaches of “overlapping mean responses” or the desirability function do not take into account the variance-covariance structure of the data nor the model parameter uncertainty. Some of the quadratic loss function approaches take into account the variance-covariance structure of the predicted means, but they do not take into account the model parameter uncertainty associated with the variance-covariance matrix of the error terms. For the optimal conditions obtained by these approaches, the probability that they provide a good multivariate response, as measured by that optimization criterion, can be unacceptably low. Furthermore, it is shown that ignoring the model parameter uncertainty can lead to reliability estimates that are too large. The proposed approach can be used with most of the current multiresponse optimization procedures to assess the reliability of a good future response. This approach takes into account the correlation structure of the data, the variability of the process distribution, and the model parameter uncertainty. The utility of this method is illustrated with two examples.
Spectral methods in general relativity and large Randall-Sundrum II black holes

Using a novel numerical spectral method, we have found solutions for large static Randall-Sundrum II (RSII) black holes by perturbing a numerical AdS5-CFT4 solution to the Einstein equation with a negative cosmological constant Λ that is asymptotically conformal to the Schwarzschild metric. We used a numerical spectral method independent of the Ricci-DeTurck-flow method used by Figueras, Lucietti, and Wiseman for a similar numerical solution. We have compared our black-hole solution to the one Figueras and Wiseman have derived by perturbing their numerical AdS5-CFT4 solution, showing that our solution agrees closely with theirs. We have obtained a closed-form approximation to the metric of the black hole on the brane. We have also deduced the new results that to first order in 1/(−ΛM2), the Hawking temperature and entropy of an RSII static black hole have the same values as the Schwarzschild metric with the same mass, but the horizon area is increased by about 4.7/(−Λ).
Anisotropic diffusion filtering of PET attenuation data to improve emission images

Attenuation correction in positron emission tomography (PET) is an essential part of clinical and research studies. However, correction using noisy transmission data acquired over short scan durations has been a problem as the noise is introduced into emission images. This study investigates the effect of smoothing the two-dimensional projections of the attenuation maps (μ-map) using the nonlinear anisotropic diffusion filtering method. Experiments are presented on a whole-body study to qualitatively evaluate the efficacy of the method in reducing the random noise and streak artefacts. The results show that image quality is significantly improved with minimal resolution loss. A reduction in statistical noise was quantitatively demonstrated when the same approach was applied to a cylindrical phantom dataset.
Mitochondrial COI Gene Sequence Variation and Taxonomic Status of Three Macrobrachium Species

Freshwater prawns (Decapoda: Caridea: Macrobrachium) play an important role in domestic fishery resources. Culturing M. rosenbergii and M. nipponense brings great economic benefits, as the two species were widely farmed in China. M. qilianensis, a native species with natural distribution limited in Gansu province, was classified into genus Macrobrachium based on external morphological characters. In order to understand the molecular genetic differences among the three species of Macrobrachium, i.e., M. rosenbergii, M. nipponense, and M. qilianensis, we analyzed sequences of mitochondrial cytochrome oxidase subunit I (COI) of them. It would provide theoretical basis of exploiting and utilizing Macrobrachium resources rationally. A total of 30 individuals (10 individuals of each species) were collected from Gansu and Zhejiang province. Samples of M. qilianensis were wild, however, that of M. rosenbergii and M. nipponense were cultured. Their mitochondrial COI gene segment sequences were obtained by using the method of PCR amplification and sequencing. After alignment, 649 bp consensus sequences of COI were obtained. One hundred and sixty-nine variable sites were detected in all 30 individuals, accounting for 26.04% of total sequence. A total of seven haplotypes were also detected. Nucleotide diversity was 0.411% within M. rosenbergii, 0.092% within M. nipponense, and 0.031% within M. qilianensis. Genetic diversity of wild M. qilianensis was much lower than that of cultured M. rosenbergii and M. nipponense. Genetic distances between different haplotypes of the three prawns ranged from 19.87% to 23.84%. It suggested that the three species were valid species, because genetic distances among them were quite great. To further determine the taxonomic status of the three prawns in family Palaemonoidae, we downloaded the corresponding COI sequences of Palaemonoidae prawns from Genbank and analyzed the phylogenetic relationships of them. Phylogenetic tree (NJ) showed that M. nipponense, M. rosenbergii and other Macrobrachium species constituted one monophyletic group. However, M. qilianensis, Exopalaemon carinicauda, and Palaemon debilis formed the other clade. Thus, results of COI sequences did not support that M. qilianensis belonged to genus Macrobrachium. The taxonomic status of M. qilianensis should be reevaluated with more comprehensive evidences.
Coulomb heating of channeled H2+ and H3+ molecules in Si

A method for forming a high aspect ration (HAR>4:1) borderless contact hole is described. The method forms a contact/via hole in the silicon oxide layer by performing an etching process with an etchant, C4F8/C2F6,/Ar/CO or C4F8/Ar/CO, on an etcher. The etcher includes a ring, a roof, a chiller and a chamber. The etchant used in the etching process is controlled under conditions including a C4F8 flow of about 10 to 20 sccm, a CO flow of about 1 to 100 sccm, and an Ar flow of about 100 to 500 sccm. The flow of C2F6 is about 0.5 to 1.5 times that of C4F8. The conditions of the etcher include a roof temperature of about 150 to 300° C. , a chiller temperature of about -20 to 20° C. , a wall temperature of about 150 to 400° C. , a ring temperature of about 150 to 400° C. , and a pressure within the chamber of about 4 to 50 mtorr. By controlling the chamber pressure and the deposition rate of the polymer molecules, a properly profiled contact hole is obtained.

A Hybrid Partially Reconfigurable Overlay Supporting Just-In-Time Assembly of Custom Accelerators on FPGAs

The state of the art in design and development flows for FPGAs are not sufficiently mature to allow programmers to implement their applications through traditional software development flows. The stipulation of synthesis as well as the requirement of background knowledge on the FPGAs’ low-level physical hardware structure are major challenges that prevent programmers from using FPGAs. The reconfigurable computing community is seeking solutions to raise the level of design abstraction at which programmers must operate, and move the synthesis process out of the programmers’ path through the use of overlays. A recent approach, Just-In-Time Assembly (JITA), was proposed that enables hardware accelerators to be assembled at runtime, all from within a traditional software compilation flow. The JITA approach presents a promising path to constructing hardware designs on FPGAs using pre-synthesized parallel programming patterns, but suffers from two major limitations. First, all variant programming patterns must be pre-synthesized. Second, conditional operations are not supported. In this thesis, I present a new reconfigurable overlay, URUK, that overcomes the two limitations imposed by the JITA approach. Similar to the original JITA approach, the proposed URUK overlay allows hardware accelerators to be constructed on FPGAs through software compilation flows. To this basic capability, URUK adds additional support to enable the assembly of presynthesized fine-grained computational operators to be assembled within the FPGA. This thesis provides analysis of URUK from three different perspectives; utilization, performance, and productivity. The analysis includes comparisons against High-Level Synthesis (HLS) and the state of the art approach to creating static overlays. The tradeoffs conclude that URUK can achieve approximately equivalent performance for algebra operations compared to HLS custom accelerators, which are designed with simple experience on FPGAs. Further, URUK shows a high degree of flexibility for runtime placement and routing of the primitive operations. The analysis shows how this flexibility can be leveraged to reduce communication overhead among tiles, compared to traditional static overlays. The results also show URUK can enable software programmers without any hardware skills to create hardware accelerators at productivity levels consistent with software development and compilation.
Development of an integrated approach based on validated and standardized methods to support the implementation of the EC recommendation for a definition of nanomaterial

The VSSA approach has the important advantage over classifying, imaging and counting techniques that it does not involve dispersion protocols. Further, the BET technique as the basis for VSSA determination it is in widespread use, generates low costs and is specified for many commercial materials. Finally, the same equipment allows for a deeper analysis by full isotherm evaluation. The present deliverable assesses all NanoDefine powders, supplemented by further real-world materials (in total 26 powders), and quantitatively compares the relationship between the median size (by Electron Microscopy – considered as benchmark for the EC nanomaterial definition) vs. the size derived from VSSA. The VSSA method mitigates the challenges of EM to assess the thickness of platelets, but worked as well on fibbers and particles of irregular shapes. A screening strategy is proposed. If applied to the further data from real-world materials as validation set, this screening does achieve a correct classification, leaving only borderline materials for tier 2 assessment.
From Toeplitz matrix sequences to zero distribution of orthogonal polynomials

We review some classical results on the zero distribution of orthogonal polynomials on the light of spectral theory for Toeplitz matrix sequences. In particular, we discuss and extend some recent results by A. Kuijlaars and W. Van Assche on orthogonal polynomials with asymptotically periodic and varying recurrence coefficients.
Bifurcations and chaos control in discrete small-world networks

An impulsive delayed feedback control strategy to control period-doubling bifurcations and chaos is proposed. The control method is then applied to a discrete small-world network model. Qualitative analyses and simulations show that under a generic condition, the bifurcations and the chaos can be delayed or eliminated completely. In addition, the periodic orbits embedded in the chaotic attractor can be stabilized.
Architecture competitions in an urban planning context

Abstract This paper analyzes discussions and controversy surrounding the architecture competitions that have been part of a large-scale waterfront redevelopment plan called the Fjord City plan in Oslo, Norway. Particular attention is given to the architectural competition for the new Edvard Munch Museum. The Fjord City waterfront development plan is organized through an entrepreneurial mode of planning and with clear neoliberal underpinnings. The paper looks at how architectural competitions are used and how they function within the context of contemporary planning.
Evaluating measurement uncertainty in fluid phase equilibrium calculations

The evaluation of measurement uncertainty in accordance with the ‘Guide to the expression of uncertainty in measurement’ (GUM) has not yet become widespread in physical chemistry. With only the law of the propagation of uncertainty from the GUM, many of these uncertainty evaluations would be cumbersome, as models are often non-linear and require iterative calculations. The methods from GUM supplements 1 and 2 enable the propagation of uncertainties under most circumstances. Experimental data in physical chemistry are used, for example, to derive reference property data and support trade—all applications where measurement uncertainty plays an important role. This paper aims to outline how the methods for evaluating and propagating uncertainty can be applied to some specific cases with a wide impact: deriving reference data from vapour pressure data, a flash calculation, and the use of an equation-of-state to predict the properties of both phases in a vapour–liquid equilibrium. The three uncertainty evaluations demonstrate that the methods of GUM and its supplements are a versatile toolbox that enable us to evaluate the measurement uncertainty of physical chemical measurements, including the derivation of reference data, such as the equilibrium thermodynamical properties of fluids.
Analysis of the 5p5d, 4f5d and 5s5f Configurations in Cd-I Like La X Ion

The spectrum of the (5p2 + 5s5d + 4f5p)–(5p5d + 4f5d + 5s5f) transitions of La X, recorded on a variety of normal and grazing incidence spectrographs, and excited in triggered vacuum spark and laser produced plasma sources, was analysed. The earlier analysis (Gayasov et al 1999 Physica Scripta 59 419) was confirmed except for the 5p2 1S0 level. Three levels of the 4f5p configuration missing in the earlier work were located. Thirty out of forty possible levels of the 5p5d, 4f5d and 5s5f configuration were established. One hundred and forty lines are now classified in La X spectrum out of which eighty-five lines are newly classified. The Hartree–Fock (HF) and parametric least-squares-fitted (LSF) calculations were carried out to interpret the spectroscopic data obtained satisfactorily. The ionization potential of La X has been calculated as 1271950±150 cm-1 (157.7±0.02 eV).
Light-cone averaging in cosmology: formalism and applications

We present a general gauge invariant formalism for defining cosmological averages that are relevant for observations based on light-like signals. Such averages involve either null hypersurfaces corresponding to a family of past light-cones or compact surfaces given by their intersection with timelike hypersurfaces. Generalized Buchert-Ehlers commutation rules for derivatives of these light-cone averages are given. After introducing some adapted ``geodesic light-cone'' coordinates, we give explicit expressions for averaging the redshift to luminosity-distance relation and the so-called ``redshift drift'' in a generic inhomogeneous Universe.
