description: Experimental evidence on high-Tc cuprates reveals ubiquitous charge density wave (CDW) modulations, which coexist with superconductivity. Although the CDW had been predicted by theory, important questions remain about the extent to which the CDW influences lattice and charge degrees of freedom and its characteristics as functions of doping and temperature. These questions are intimately connected to the origin of the CDW and its relation to the mysterious cuprate pseudogap. Here, we use ultrahigh resolution resonant inelastic x-ray scattering (RIXS) to reveal new CDW character in underdoped Bi2Sr2CaCu2O8+δ (Bi2212). At low temperature, we observe dispersive excitations from an incommensurate CDW that induces anomalously enhanced phonon intensity, unseen using other techniques. Near the pseudogap temperature T*, the CDW persists, but the associated excitations significantly weaken and the CDW wavevector shifts, becoming nearly commensurate with a periodicity of four lattice constants. The dispersive CDW excitations, phonon anomaly, and temperature dependent commensuration provide a comprehensive momentum space picture of complex CDW behavior and point to a closer relationship with the pseudogap state.

description: Anion exchange membranes (AEMs) are key core materials in water electrolysis, requiring both high conductivity and good dimensional stability and chemical durability. In this work, a series of poly(biphenyl piperidinium) AEMs with side octadecyl groups (Q18PBP-x) are prepared through the superacid catalyzed polymerization and grafting reactions. The long hydrophobic alkyl side chains attached onto the ether-free backbone effectively improve the dimensional stability, chemical durability and ionic conductivity of the obtained AEMs at high temperature. At 80 °C, the water absorption and swelling rate of Q18PBP-30 membrane with IEC of 2.28 mmol g−1 are 47.8 and 10.8%, respectively. Its ionic conductivity is 79.4 mS cm−1 and only decrease by 6.9% after 480 h of immersion in 2 M NaOH at 80 °C. The current density of water electrolyzer assembled with representative Q18PBP-30 membrane reaches 0.53 A cm−2 in 2 M KOH at 2.1 V, and its voltage fluctuation of durability testing is only 15.8% after 480 h at the current density of 300 mA cm−2. These results suggest that grafting long hydrophobic alkyl chains on the backbone of AEMs is a promising strategy to enhance their properties for water electrolysis.
Exotic Superconductivity in the Extended Attractive Hubbard Model

Year: 2017
Subjects: subject: Superconductivity (cond-mat.supr-con)

description: We show that the extended attractive Hubbard model on a square lattice hosts a variety of superconducting phases, including exotic mixed-symmetry phases with $d_{x^2-y^2} + {\rm i} [s + d_{x^2+y^2}]$ and $ d_{x^2-y^2} + p_{x}$ symmetries, and a novel $p_x + {\rm i} p_y$ state. The calculations are performed within the mean-field Bogoliubov-deGennes (BdG) framework. The ground states of the BdG Hamiltonian are obtained via a minimization scheme that does not impose symmetry constraints on the superconducting solutions, hence allowing a mixing of $s$-, $p$- and $d$-wave order parameters. Our results show that extended attractive Hubbard model can serve as an effective model for investigating properties of exotic superconducting states.

description: We propose an experiment to look for possible small violations of the symmetrization postulate of Quantum Mechanics, in systems composed by three identical particles. Such violations could be detected by investigating the population of particular roto-vibrational states of symmetrical molecules containing three identical nuclei. We discuss the symmetry properties of such states, and the implications of the symmetrization postulate and of the spin-statistics. A high sensitivity spectroscopic investigation on simple molecules such as SO3, BH3 and NH3 could lead to the first test of the symmetrization postulate for spin-0 and spin-1/2 nuclei.

description: We have detected H$_2$O and O$_2$ absorption against the far-UV continuum of stars located on lines of sight near the nucleus of Comet 67P/Churyumov-Gerasimenko using the Alice imaging spectrograph on Rosetta. These stellar appulses occurred at impact parameters of $ρ=4$-20 km, and heliocentric distances ranging from $R_h=-1.8$ to 2.3 AU (negative values indicate pre-perihelion observations). The measured H$_2$O column densities agree well with nearly contemporaneous values measured by VIRTIS-H. The clear detection of O$_2$ independently confirms the initial detection by the ROSINA mass spectrometer; however, the relative abundance of O$_2$/H$_2$O derived from the stellar spectra (11%-68%, with a median value of 25%) is considerably larger than published values found by ROSINA. The cause of this difference is unclear, but potentially related to ROSINA measuring number density at the spacecraft position while Alice measures column density along a line of sight that passes near the nucleus.

description: The paper considers software development issues for large-scale enterprise information systems (IS) with databases (DB) in global heterogeneous distributed computational environment. Due to high IT development rates, the present-day society has accumulated and rapidly increases an extremely huge data burden. Manipulating with such huge data arrays becomes an essential problem, particularly due to their global distribution, heterogeneous and weak-structured character. The conceptual approach to integrated Internet-based IS design, development and implementation is presented, including formal models, software development methodology and original software development tools for visual problem-oriented development and content management. IS implementation results proved shortening terms and reducing costs of implementation compared to commercial software available.

description: In this work, the structural stability and the electronic properties of LiNiBO 3 and LiFe x Ni (1-x) BO 3 are studied using first principle calculations based on density functional theory. The calculated structural parameters are in good agreement with the available theoretical data. The most stable phases of the Fe substituted systems are predicted from the formation energy hull generated using the cluster expansion method. The 66% of Fe substitution at the Ni site gives the most stable structure among all the Fe substituted systems. The bonding mechanisms of the considered systems are discussed based on the density of states (DOS) and charge density plot. The detailed analysis of the stability, electronic structure, and the bonding mechanisms suggests that the systems can be a promising cathode material for Li ion battery applications.

description: We present images from five observations of the quasar 3C 273 with the Chandra X-ray Observatory. The jet has at least four distinct features which are not resolved in previous observations. The first knot in the jet (A1) is very bright in X-rays. Its X-ray spectrum is well fitted with a power law with alpha = 0.60 +/- 0.05. Combining this measurement with lower frequency data shows that a pure synchrotron model can fit the spectrum of this knot from 1.647 GHz to 5 keV (over nine decades in energy) with alpha = 0.76 +/- 0.02, similar to the X-ray spectral slope. Thus, we place a lower limit on the total power radiated by this knot of 1.5e43 erg/s; substantially more power may be emitted in the hard X-ray and gamma-ray bands. Knot A2 is also detected and is somewhat blended with knot B1. Synchrotron emission may also explain the X-ray emission but a spectral bend is required near the optical band. For knots A1 and B1, the X-ray flux dominates the emitted energy. For the remaining optical knots (C through H), localized X-ray enhancements that might correspond to the optical features are not clearly resolved. The position angle of the jet ridge line follows the optical shape with distinct, aperiodic excursions of +/-1 deg from a median value of -138.0deg. Finally, we find X-ray emission from the ``inner jet'' between 5 and 10" from the core.

description: Use of ultrasound as an additional source for promoting polymerization reactions has gained great attention. Phase transfer catalyst (PTC) along with ultrasonication in polymerization process is an attractive methodology to achieve good yield and realizing principles of green chemistry. Herein, we reported the facile polymerization of synthesized novel N-butenyl isatin (NBI) at 60 ± 2 °C with and without ultrasonic irradiation (45 kHz; 550 W) using dual-site phase transfer catalyst (1, 4-bis (triethyl methyl ammonium) benzene dibromide, TEMABDB) and potassium peroxydisulphate (PDS or PPS) as initiator. Ultrasonication (US) promotes the formation of reactive radicals, which can be utilized effectively in phase transfer polymerization process. Hence, the rate was multi-folded (twice) in comparison with silent condition. The effect of sonication frequency and various reaction parameters on the polymerization process were investigated in both conditions. An enhancement of reaction rate under sonication was validated by activation parameter. Synthesized monomer and poly (N-butenyl isatin) was characterized by different spectral methods. Facile polymerization of N-butenyl isatin by sonication aided dual-site PTC. Green approach and mild conditions used for polymerization of NBI. Sonication lifts the rate significantly in comparison with standard condition. Effects of variables in polymerization rate were explored in both conditions. Poly (N-butenyl isatin) was analyzed by different spectral techniques.

description: No abstracts are to be cited without prior reference to the author.Coastal ecosystems are faced with a variety of environmental stresses, and the concept of ecosystem health has become increasingly attractive to both regulators and the public. Many indicators of ecosystem health have been derived, many of them data-intensive, such as those relying on benthic biodiversity. In addition to large effort, they yield information after the occurrence of impacts or other detriments to environmental quality. Prediction of impacts a priori would be more useful from a management standpoint. Although various models have predictive capability, their spin-up time may be long, requiring data that are not available for a given site. In a new research program, we therefore use system-level properties (flushing, morphology, pollutant load, etc.) to develop index-type models for coastal ecosystems. Moreover, we examine the statistical properties of their construction (error terms, non-linearity) to make them more quantitative in application. Groundtruthing of index models will be undertaken at study sites on both coasts of Canada, using data from well-known sites. In addition, a decision support tool based on combining/weighting the indices will be developed.

description: We present an unsupervised learning algorithm that mines large text corpora for patterns that express implicit semantic relations. For a given input word pair X:Y with some unspecified semantic relations, the corresponding output list of patterns is ranked according to how well each pattern Pi expresses the relations between X and Y. For example, given X=ostrich and Y=bird, the two highest ranking output patterns are "X is the largest Y" and "Y such as the X". The output patterns are intended to be useful for finding further pairs with the same relations, to support the construction of lexicons, ontologies, and semantic networks. The patterns are sorted by pertinence, where the pertinence of a pattern Pi for a word pair X:Y is the expected relational similarity between the given pair and typical pairs for Pi. The algorithm is empirically evaluated on two tasks, solving multiple-choice SAT word analogy questions and classifying semantic relations in noun-modifier pairs. On both tasks, the algorithm achieves state-of-the-art results, performing significantly better than several alternative pattern ranking algorithms, based on tf-idf.

description: No abstracts are to be cited without prior reference to the author.Strong and viable fish populations are a prerequisite for ecosystem functioning and sustainable fisheries. Recruitment success is often identified as critical for adult population size which is available for fisheries and ecosystem services. However, the data needed to quantify habitat productivity relationships is often lacking. For this we need spatial estimates of recruitment habitats together with estimates of adult population sizes from a number of populations. In order to test potential life stage-specific bottlenecks we have modelled the distribution of spawning- and young-of-the-year habitats for Eurasian perch (Perca fluviatilis L.) within a large archipelago area in the Baltic Sea. Estimates of spawning and nursery habitat availability were based on species distribution models that relate the response variables to environmental variables. Using geographic information systems and generalized additive models, maps of the environmental variables were recalculated into recruitment habitat suitability maps. Within the study area local population size estimates were obtained from standardized gillnet monitoring. The correlation between recruitment habitats and adult population sizes yielded quantitative estimates of how availability of spawning and nursery habitats influences adult population size. These results should be of particular interest for fisheries and conservation managers interested in assessing alternative management scenarios and their potential cost and ultimately addressing the question of “How much habitat is enough?”.

description: No abstracts are to be cited without prior reference to the author.Fishery has been one of the most important economic activities for the inhabitants of the coastal villages in Estonia for centuries. However, since the mid of 1990s the efficiency of coastal fishery as well as the number of professional fishermen has declined significantly because the both, recent overexploitation of many local fish stocks and lack of the reasonable management strategy. This has resulted in serious social problems like high proportion of part time employees among coastal habitants; decrease of local population and in overall survival capabilities of coastal communities. In 20062007 an EstonianFinnish INTERREG IIIA project was carried out and in 2008 some additional studies were performed using the bottomup strategy (participatory governance) with the participation of the representatives from coastal communities with the aim to find the conceptual strategy of the development of Estonian coastal fishery. The SWOT analysis of outcome of the interviews with the professional fishermen by regions was performed. It was found that in principle, the sustainable smallscale fishery as well, as the survival of coastal villages can be possible when the integrated coastal area management strategy will be implemented and supported at the level of the Government, County Authorities and Municipalities.

Hermite-Padé approximants have been used to extract the location of the branch cut of the series with unprecendented accuracy ($100$ digits). Both series have then been resummed using an approach based on Padé approximants, where the exact asymptotic behaviors of the period and the amplitude are taken into account. Our results improve drastically all previous results obtained on this subject.

description: Optical coherence tomography (OCT), a non-contact, non-destructive imaging technique, is becoming a popular tool in phytophotonics, helping to address research questions in plant biology and horticulture. However, the stationary nature of typical OCT systems compromises its non-destructive advantage since plants often need to be dissected for an analysis with a laboratory OCT system. Here we present a portable, low-cost OCT system that enables in-situ measurements of plants. We outline technical challenges encountered during the development and showcase initial measurements of different plant tissues. Copyright 2024 Society of Photo-Optical Instrumentation Engineers.

On the origin of noisy states whose teleportation fidelity can be enhanced through dissipation

Year: 2000

description: Recently Badziag \emph{et al.} \cite{badziag} obtained a class of noisy states whose teleportation fidelity can be enhanced by subjecting one of the qubits to dissipative interaction with the environment via amplitude damping channel (ADC). We show that such noisy states result while sharing the states (| Φ^{\pm}> =\frac{1}{\sqrt{2}}(| 00> \pm | 11>)) across ADC. We also show that under similar dissipative interactions different Bell states give rise to noisy entangled states that are qualitatively very different from each other in the sense, only the noisy entangled states constructed from the Bell states (| Φ^{\pm}>) can \emph{}be made better sometimes by subjecting the unaffected qubit to a dissipative interaction with the environment. Importantly if the noisy state is non teleporting then it can always be made teleporting with this prescription. We derive the most general restrictions on improvement of such noisy states assuming that the damping parameters being different for both the qubits. However this curious prescription does not work for the noisy entangled states generated from (| Ψ^{\pm}> =\frac{1}{\sqrt{2}}(| 01> \pm | 10>)). This shows that an apriori knowledge of the noisy channel might be helpful to decide which Bell state needs to be shared between Alice and Bob. \emph{}

description: In this work we seek evidence for global torsional oscillations in alpha sunspots. We have used long time series of continuum intensity and magnetic field vector maps from the Helioseismic and Magnetic Imager (HMI) instrument on board the Solar Dynamics Observatory (SDO) spacecraft. The time series analysed here span the total disk passage of 25 isolated sunspots. We found no evidence of global long-term periodic oscillations in the azimuthal angle of the sunspot magnetic field within $\sim$ 1 degree. This study could help us to understand the sunspot dynamics and its internal structure.

description: In this paper we study convergence estimates for a multigrid algorithm with smoothers of successive subspace correction (SSC) type, applied to symmetric elliptic PDEs. First, we revisit a general convergence analysis on a class of multigrid algorithms in a fairly general setting, where no regularity assumptions are made on the solution. In this framework, we are able to explicitly highlight the dependence of the multigrid error bound on the number of smoothing steps. For the case of no regularity assumptions, this represents a new addition to the existing theory. Then, we analyze successive subspace correction smoothing schemes for a set of uniform and local refinement applications with either nested or non-nested overlapping subdomains. For these applications, we explicitly derive bounds for the multigrid error, and identify sufficient conditions for these bounds to be independent of the number of multigrid levels. For the local refinement applications, finite element grids with arbitrary hanging nodes configurations are considered. The analysis of these smoothing schemes is cast within the far-reaching multiplicative Schwarz framework.

description: Hyperspectral imaging is a key technology for monitoring agricultural crops and vegetation. It can be used for health estimation and the early detection of disease symptoms in plants. This can help to reduce the use of pesticides by allowing targeted and early intervention. Cost-efficient hyperspectral imaging systems are necessary to meet the increasing demand for monitoring techniques for agricultural products. These systems usually suffer from sub-optimal image quality. Here we present a digital aberration correction for hyperspectral image data.

description: We determine the normalisation of scalar and pseudoscalar current operators made from non-relativistic $b$ quarks and Highly Improved Staggered light quarks in lattice Quantum Chromodynamics (QCD) through $\mathcal{O}(α_s)$ and $Λ_{\text{QCD}}/m_b$. We use matrix elements of these operators to extract $B$ meson decay constants and form factors, then compare to those obtained using the standard vector and axial-vector operators. This provides a test of systematic errors in the lattice QCD determination of the $B$ meson decay constants and form factors. We provide a new value for the $B$ and $B_s$ meson decay constants from lattice QCD calculations on ensembles that include $u$, $d$, $s$ and $c$ quarks in the sea and those which have the $u/d$ quark mass going down to its physical value. Our results are $f_B=0.196(6)$ GeV, $f_{B_s}=0.236(7)$ GeV and $f_{B_s}/f_B =1.207(7)$, agreeing well with earlier results using the temporal axial current. By combining with these previous results, we provide updated values of $f_B=0.190(4)$ GeV, $f_{B_s}=0.229(5)$ GeV and $f_{B_s}/f_B = 1.206(5)$.

description: We present photometry and analysis of the microlensing alert MACHO 96-LMC-2. The ~3% photometry provided by the Global Microlensing Alert Network follow--up effort reveals a periodic modulation in the lightcurve. We attribute this to binarity of the lensed source. Microlensing fits to a rotating binary source magnified by a single lens converge on two minima, separated by delta chi^2 ~ 1. The most significant fit X1 predicts a primary which contributes ~100% of the light, a dark secondary, and an orbital period (T) of 9.2 days. The second fit X2 yields a binary source with two stars of roughly equal mass and luminosity, and T = 21.2 days. The lensed object appears to lie on the upper LMC main sequence. We estimate the mass of the primary component of the binary system, M ~2 M_sun. For the preferred model X1, we explore the range of dark companions by assuming 0.1 M_sun and 1.4 M_sun objects in models X1a and X1b, respectively. We find lens velocities projected to the LMC in these models of v^hat_X1a = 18.3 +/- 3.1 km/s and v^hat_X1b = 188 +/- 32 k/ms. In both these cases, a likelihood analysis suggests an LMC lens is preferred over a Galactic halo lens, although only marginally so in model X1b. We also find v^hat_X2 = 39.6 +/- 6.1 k/ms, where the likelihood for the lens location is strongly dominated by the LMC disk. In all cases, the lens mass is consistent with that of an M-dwarf. The LMC self-lensing rate contributed by 96-LMC-2 is consistent with model self-lensing rates. (Abridged)

description: No abstracts are to be cited without prior reference to the author.How do the ecological impacts of fishing on marine ecosystems compare around the World? Here we present a comparative approach to analyse the impacts of fishing on a range of ecosystems using a suite of readily understood ecosystem indicators (Table 1), based on the work of the Eur-Oceans IndiSeas1 working group (6): “EAF indicators: a comparative approach across ecosystems”. The aim of this work is (1) to rank a set of ecosystems according to the extent of fishing impacts by testing different methods and using current states and short to long-term trends, (2) to evaluate this ranking when considering conservation goals, and (3) to compare the ranking of ecosystems on a multivariate basis and with previous comparative approaches. Firstly, current ecosystem states are compared by examining the mean values of these indicators in recent years. Secondly, trends of indicators are compared with expected trends over time. Slopes of the trends and their significance are assessed across ecosystems using short, standardized time series of data. The ecosystems are then ranked according to sub-categories of indicators addressing four ecological goals: (a) conservation of biodiversity (CB), (b) ecosystem stability and resistance to perturbations (SR), (c) ecosystem structure and functioning (EF), and (d) resource potential (RP). A way of combining these ranks by weighting the selected indicators by conservation goal and taking into account redundancy of indicators is proposed. Results facilitate classification of ecosystems into moderate to highly impacted categories and show improving or deteriorating trends, thus enabling identification of desired or undesired situations (see an example in Figure 1). Cross-comparing relative states and recent trends of exploited ecosystems using ranking methods can be a powerful tool to illustrate, in a simple way, the impacts of fishing on ecosystem dynamics. Subsequently, similarities and differences between ecosystems are further explored using multivariate analyses and testing of explanatory factors. General patterns in ecosystem status at a broad scale are analysed and interpreted taking into account ecological and environmental features, and ecosystem expertise. This work provides an example of how, in the context of EAF, the previously agreed suite of indicators can be used to rank and assess the relative ecological status of exploited marine ecosystems, taking into account their different fishing and ecological histories.

description: The reliable detection of vulnerable road users and the assessment of the actual vulnerability is an important task for the collision warning algorithms of driver assistance systems. Current systems make assumptions about the road geometry which can lead to misclassification. We propose a deep learning-based approach to reliably detect pedestrians and classify their vulnerability based on the traffic area they are walking in. Since there are no pre-labeled datasets available for this task, we developed a method to train a network first on custom synthetic data and then use the network to augment a customer-provided training dataset for a neural network working on real world images. The evaluation shows that our network is able to accurately classify the vulnerability of pedestrians in complex real world scenarios without making assumptions on road geometry.
