description: Three cometary-shaped objects in the giant HII region NGC 3603, originally found and identified as proto-planetary disks (ProPlyDs) by Brandner et al. 2000 using HST+VLT in the optical and near-infrared, have been detected with the Australia Telescope Compact Array (ATCA) in the radio continuum at 3 and 6cm. All three ProPlyD-like objects are clearly resolved with an extent of a few arcseconds. The integrated 6cm fluxes are up to 1.3 times higher than the 3cm fluxes with spectral indices averaged over the whole clump between $α=-0.1$ and -0.5 ($S_ν\propto ν^α$), indicating the likely presence of non-thermal emission in at least some of the sources. All measured fluxes are at least one order of magnitude higher than those predicted by Brandner et al. 2000. Due to the unexpectedly large radio luminosities of the ProPlyD-like features and because the radio emission is extended a (proto-)stellar origin of the non-thermal emission from a dust enshrouded star appears unlikely. Instead we propose that magnetized regions within the envelope of the ProPlyD-like nebulae exist. (abridged)

description: We investigate the recently developed Bidirectional Encoder Representations from Transformers (BERT) model for the hyperpartisan news detection task. Using a subset of hand-labeled articles from SemEval as a validation set, we test the performance of different parameters for BERT models. We find that accuracy from two different BERT models using different proportions of the articles is consistently high, with our best-performing model on the validation set achieving 85% accuracy and the best-performing model on the test set achieving 77%. We further determined that our model exhibits strong consistency, labeling independent slices of the same article identically. Finally, we find that randomizing the order of word pieces dramatically reduces validation accuracy (to approximately 60%), but that shuffling groups of four or more word pieces maintains an accuracy of about 80%, indicating the model mainly gains value from local context.

description: This paper provides a comparison between the vibrational-specific state-to-state (StS) model for nitrogen plasma elaborated in Part I of this work and conventional two-temperature (2-T) models for simulating inductively coupled plasma (ICP) discharges under non-Local Thermodynamic Equilibrium (NLTE) conditions. Simulations are performed within the multi-physics computational framework established for ICP in Part I. Based on the findings of Part I, the quasi-steady-state (QSS) assumption is validated in the plasma core, thereby enabling the calculation of global rate coefficients under this assumption. This facilitates the reduction of the StS model to a "consistent" macroscopic 2-T model. Results from the StS model for nitrogen ICP torch exhibit considerable discrepancies when compared against predictions from the widely utilized Park 2-T model. On the contrary, the comparison between the newly proposed 2-T model, consistently derived from the original vibronic StS model, and the full StS results demonstrate excellent agreement in terms of plasma core location, morphology, and peak temperature distributions. This demonstrates the ability of the proposed 2-T model to capture the energy transfer and reactive processes predicted by the comprehensive StS model. Additionally, the study identifies the vibrational-translational (VT) energy transfer term in the 2-T model as the predominant factor in dictating plasma core morphology. This suggests a strong sensitivity of the ICP flow field to heavy-impact vibrational excitations and dissociative events.

This article evaluates the potential welfare effects of adopting genetically modified crops in Russia, focusing on the potential benefits to Russian producers who adopt herbicide tolerant corn and soybeans. Calculations are based on supply and demand functions of current market situations and their potential shifts. The results quantify the potential monetary gains from open markets to genetic engineering technology and explain the potential additional costs related to technology adoption.
Optimized entanglement for quantum parameter estimation from noisy qubits

Publisher: name: arXiv
Year: 2019
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: For parameter estimation from an $N$-component composite quantum system, it is known that a separable preparation leads to a mean-squared estimation error scaling as $1/N$ while an entangled preparation can in some conditions afford a smaller error with $1/N^2$ scaling. This quantum superefficiency is however very fragile to noise or decoherence, and typically disappears with any small amount of random noise asymptotically at large $N$. To complement this asymptotic characterization, we characterize how the estimation efficiency evolves as a function of the size $N$ of the entangled system and its degree of entanglement. We address a generic situation of qubit phase estimation, also meaningful for frequency estimation. Decoherence is represented by the broad class of noises commuting with the phase rotation, which includes depolarizing, phase-flip, and thermal quantum noises. In these general conditions, explicit expressions are derived for the quantum Fisher information quantifying the ultimate achievable efficiency for estimation. We confront at any size $N$ the efficiency of the optimal separable preparation to that of an entangled preparation with arbitrary degree of entanglement. We exhibit the $1/N^2$ superefficiency with no noise, and prove its asymptotic disappearance at large $N$ for any non-vanishing noise configuration. For maximizing the estimation efficiency, we characterize the existence of an optimum $N_{\rm opt}$ of the size of the entangled system along with an optimal degree of entanglement. For nonunital noises, maximum efficiency is usually obtained at partial entanglement. Grouping the $N$ qubits into independent blocks formed of $N_{\rm opt}$ entangled qubits restores at large $N$ a nonvanishing efficiency that can improve over that of $N$ independent qubits optimally prepared. One inactive qubit in the entangled probe sometimes is most efficient for estimation.

description: China is enlisting information communication technologies (ICTs) and citizens to address gaps in environmental management. In this paper, we empirically evaluate ICT-facilitated, citizen-generated data collection through China’s “Black and Smelly Waters Program.” Utilizing the app’s citizen reports and water quality data in Guangzhou, we assess whether the reports led to significant improvement in four common water quality indicators. We found water bodies that received citizen reports had poorer levels of water quality than those that did not receive complaints. Through a fixed effects regression model, we find that COD levels decreased by 36.3% and 38.9% five and six months after reports were made. We did not observe a significant effect on other water indicators considered. We conclude that China’s preliminary experience suggests ICT-enabled citizen engagement, combined with strengthening governance through political avenues, may enable governments to overcome challenges related to implementing top-down policies and fostering civic participation.

description: Transformation of large agribusiness corporations in Serbia is at its beginning. Institutional investors are taking control of these firms through foreign direct investments. Corporate reorganization of agribusinesses starts up by introducing efficient management, information technology, Net and e-commerce. IT environment generates a new business model, which creates connections in Serbia between the large agribusinesses, business processes and IT. The market of agricultural production in Serbia is rapidly changing and adapting itself to the global trends, mainly to the Internet economy. The speed of transactions and volume of information is increasing dramatically. It is important to explain the basic economic principles at macro and micro levels. Such revolutionary changes affect the operations and management of agribusiness on the Internet and outside of it. The purpose of this work is to stimulate further research in these processes, and to use the acquired knowledge as a tool for efficient corporate agribusiness management.

description: A surprising "planar" thermal Hall effect, whereby the field is parallel to the current, has recently been observed in a few magnetic insulators, and this has been attributed to exotic excitations such as Majorana fermions or chiral magnons. Here we investigate the possibility of a planar thermal Hall effect in three different cuprate materials, in which the conventional thermal Hall conductivity $κ_{\rm {xy}}$ (with an out-of-plane field perpendicular to the current) is dominated by either electrons or phonons. Our measurements show that the planar $κ_{\rm {xy}}$ from electrons in cuprates is zero, as expected from the absence of a Lorentz force in the planar configuration. By contrast, we observe a sizable planar $κ_{\rm {xy}}$ in those samples where the thermal Hall response is due to phonons, even though it should in principle be forbidden by the high crystal symmetry. Our findings call for a careful re-examination of the mechanisms responsible for the phonon thermal Hall effect in insulators.

description: Existing methods for CWS usually rely on a large number of labeled sentences to train word segmentation models, which are expensive and time-consuming to annotate. Luckily, the unlabeled data is usually easy to collect and many high-quality Chinese lexicons are off-the-shelf, both of which can provide useful information for CWS. In this paper, we propose a neural approach for Chinese word segmentation which can exploit both lexicon and unlabeled data. Our approach is based on a variant of posterior regularization algorithm, and the unlabeled data and lexicon are incorporated into model training as indirect supervision by regularizing the prediction space of CWS models. Extensive experiments on multiple benchmark datasets in both in-domain and cross-domain scenarios validate the effectiveness of our approach.

We evaluate the partition function by using the boundary state formulation and find that it is in complete agreement with the result obtained in the boundary string field theory. It suggests that the open string higher loop diagrams may be produced consistently by a closed string field theory, where the D-brane plays a role of source for the closed string field.

description: Let $P(x)$ be a real polynomial of degree $2g+1$, $H=y^2+P(x)$ and $δ(h)$ be an oval contained in the level set $\{H=h\}$. We study complete Abelian integrals of the form $$I(h)=\int_{δ(h)} \frac{(α_0+α_1 x+... + α_{g-1}x^{g-1})dx}{y}, h\in Σ,$$ where $α_i$ are real and $Σ\subset \R$ is a maximal open interval on which a continuous family of ovals $\{δ(h)\}$ exists. We show that the $g$-dimensional real vector space of these integrals is not Chebyshev in general: for any $g>1$, there are hyperelliptic Hamiltonians $H$ and continuous families of ovals $δ(h)\subset\{H=h\}$, $h\inΣ$, such that the Abelian integral $I(h)$ can have at least $[\frac32g]-1$ zeros in $Σ$. Our main result is Theorem \ref{main} in which we show that when $g=2$, exceptional families of ovals $\{δ(h)\}$ exist, such that the corresponding vector space is still Chebyshev.

description: The African region represents the weak point of the world economy. Many African countries have still not finished the process of transforming their economy. Agriculture represents only a minor portion of their economies’ performance – however it is still a key sector of the economy (especially considering the number of people working in agriculture or people representing the agricultural population). The agricultural sector in many sub-Saharan countries is extremely sensitive and its stability affects the stability of the whole region. A very good example representing sub-Saharan Africa is the Democratic Republic of Congo (DRC). It is a country with a lot of potential, but it is classified among the poorest countries in the world. Its economy is extremely weak (despite its significant share in total GDP formation value), and underdeveloped. The share of agriculture in total GDP formation is over 42.5%. The number of people living in rural areas represents over 45 million out of a total of 75 million. The number of people working in agriculture is over 60% of the total economically active population. The economy of the country is extremely poor and fragile, mainly because of political instability. The aim of this paper is firstly to specify the position of agriculture in the DRC economy, and also to specify the production and trade commodity structure in relation to other African countries. The paper’s ambition is to identify the most perspective commodities (groups of commodities), both for production and also for trade, and to recommend such a production and trade profile which would allow the DRC the possibility of improving its competitiveness - not only in relation to other African countries, but also in relation to the global market. The production and trade commodity structures are analysed through the application of the BCG method and competitiveness analysis. In relation to these objectives, the paper provides the following conclusions. The position of agriculture in the DRC economy is stable one. Furthermore, agriculture probably represents the most stable part of the DRC economy. According to the portfolio and competitiveness analyses, the most important commodity items for the DRC are the following: Rice paddy, Maize, and Cassava. The most competitive trade items are particularly Coffee, Tea, and Cocoa, and Sugar Raw centrifugal. The most notable weakness of DRC agriculture is the production of Wheat, Beverages, Poultry Meat, and Fixed Vegetable Oils.

description: The paper deals with an estimate and analysis of the value of regional net fixed capital stock and the age structure of machinery and equipment in Czech agriculture. In order to perform such analysis, the official model of perpetual inventory method is transformed into the Markov chain model and applied on regional data separately. Regional net fixed capital stock is presented for the period of 2008-2013. The development of the average age of machinery and equipment comprises a potential indicator of the modernisation process in the industry. The analysis of the age structure is based on the structure heterogeneity indicator. For these purposes, the real age structure in each Czech region is compared with the theoretical stable and stationary structure. Currently, the most heterogeneous age structure of machinery and equipment occurs in Prague and the Karlovy Vary region.

description: We present upgraded infrastructure for Searches after Gravitational Waves Using ARizona Observatories (SAGUARO) during LIGO, Virgo, and KAGRA's fourth gravitational-wave (GW) observing run (O4). These upgrades implement many of the lessons we learned after a comprehensive analysis of potential electromagnetic counterparts to the GWs discovered during the previous observing run. We have developed a new web-based target and observation manager (TOM) that allows us to coordinate sky surveys, vet potential counterparts, and trigger follow-up observations from one centralized portal. The TOM includes software that aggregates all publicly available information on the light curves and possible host galaxies of targets, allowing us to rule out potential contaminants like active galactic nuclei, variable stars, solar-system objects, and preexisting supernovae, as well as to assess the viability of any plausible counterparts. We have also upgraded our image-subtraction pipeline by assembling deeper reference images and training a new neural network-based real-bogus classifier. These infrastructure upgrades will aid coordination by enabling the prompt reporting of observations, discoveries, and analysis to the GW follow-up community, and put SAGUARO in an advantageous position to discover kilonovae in the remainder of O4 and beyond. Many elements of our open-source software stack have broad utility beyond multimessenger astronomy, and will be particularly relevant in the "big data" era of transient discoveries by the Vera C. Rubin Observatory.

description: We introduce a strategy to develop optimally designed fields for continuous dynamical decoupling. Using our methodology, we obtain the optimal continuous field configuration to maximize the fidelity of a general one-qubit quantum gate. To achieve this, considering dephasing-noise perturbations, we employ an auxiliary qubit instead of the boson bath to implement a purification scheme, which results in unitary dynamics. Employing the sub-Riemannian geometry framework for the two-qubit unitary group, we derive and numerically solve the geodesic equations, obtaining the optimal time-dependent control Hamiltonian. Also, due to the extended time required to find solutions to the geodesic equations, we train a neural network on a subset of geodesic solutions, enabling us to promptly generate the time-dependent control Hamiltonian for any desired gate, which is crucial in circuit optimization.

description: This article examines the current trend toward solving issues of procurement and processing of publicly disclosed pollution source data in China, where this data is characterized by heterogeneity and lack of standardization. Through ethnography and software analysis, the article examines the hidden labor entailed in automation using the case study of a Chinese e-NGO. We identify the bulk of this labor in “datascape navigation”, or the practices needed to locate, acquire and process the desired information within the infrastructure enabling the circulation of the data. The aspects of this labor are examined in relation to two data flows: enterprise environmental supervision records and information about real-time emissions. We identify several forms of unpredicted human and non-human labor entailed by both unsuccessful and successful automation attempts. We conclude that the labor involved by software automation of environmental data procurement and processing can critically impact environmental disclosure timing and quality.

In contrast with the (ungauged) Skyrme model, where the effect of this potential on the solitons is marginal, here it turns out to be decisive, resulting in very different dependence of the energy as a function of the Skyrme coupling constant.

description: We study $q$-series-valued invariants of 3-manifolds that depend on the choice of a root system $G$. This is a natural generalization of the earlier works by Gukov-Pei-Putrov-Vafa [arXiv:1701.06567] and Gukov-Manolescu [arXiv:1904.06057] where they focused on $G={\rm SU}(2)$ case. Although a full mathematical definition for these ''invariants'' is lacking yet, we define $\hat{Z}^G$ for negative definite plumbed 3-manifolds and $F_K^G$ for torus knot complements. As in the $G={\rm SU}(2)$ case by Gukov and Manolescu, there is a surgery formula relating $F_K^G$ to $\hat{Z}^G$ of a Dehn surgery on the knot $K$. Furthermore, specializing to symmetric representations, $F_K^G$ satisfies a recurrence relation given by the quantum $A$-polynomial for symmetric representations, which hints that there might be HOMFLY-PT analogues of these 3-manifold invariants.

description: Hybrid nanofibers based on ZnO loaded activated carbon nanofibers (ZnO-ACNFs) are proposed here for the elimination of hazardous lead from aqueous solutions. The prepared ZnO nanoscale material was loaded into the polyacrylonitrile nanofibers (PAN NFs) which were later carbonized by using a novel method named as a plate-sandwich method. The Synthesized nanofibrous composite was characterized by SEM, TEM, EDX, FTIR and XRD techniques to analyze its chemical and morphological properties. Moreover, the nanocomposite was efficaciously applied for the lead (Pb2+) ions removal from wastewater and simulated water through continuous filtration and batch filtration. The ZnO-ACNFs membrane showed outstanding results in adsorptive removal, giving adsorption capacity of 92.59 mg/g within the contact time of 45 min. Compared to their counterparts (ZnO and CNFs), the hybrid ZnO-ACNFs showed excellent performance in removing toxic lead.

description: Chinese named entity recognition (CNER) is an important task in Chinese natural language processing field. However, CNER is very challenging since Chinese entity names are highly context-dependent. In addition, Chinese texts lack delimiters to separate words, making it difficult to identify the boundary of entities. Besides, the training data for CNER in many domains is usually insufficient, and annotating enough training data for CNER is very expensive and time-consuming. In this paper, we propose a neural approach for CNER. First, we introduce a CNN-LSTM-CRF neural architecture to capture both local and long-distance contexts for CNER. Second, we propose a unified framework to jointly train CNER and word segmentation models in order to enhance the ability of CNER model in identifying entity boundaries. Third, we introduce an automatic method to generate pseudo labeled samples from existing labeled data which can enrich the training data. Experiments on two benchmark datasets show that our approach can effectively improve the performance of Chinese named entity recognition, especially when training data is insufficient.

High efficiency photon counting using stopped light

description: Single-photon detection and photon counting play a central role in a large number of quantum communication and computation protocols. While the efficiency of state-of-the-art photo-detectors is well below the desired limits, quantum state measurements in trapped ions can be carried out with efficiencies approaching 100%. Here, we propose a method that can in principle achieve ideal photon counting, by combining the techniques of photonic quantum memory and ion-trap fluorescence detection: after mapping the quantum state of a propagating light pulse onto metastable collective excitations of a trapped cold atomic gas, it is possible to monitor the resonance fluorescence induced by an additional laser field that only couples to the metastable excited state. Even with a photon collection/detection efficiency as low as 10%, it is possible to achieve photon counting with efficiency approaching 100%.

description: SnS and SnSe are isoelectronic materials with a common phase diagram. Recently, SnSe was found to be the most efficient intrinsic thermoelectric material in its high-temperature Cmcm phase above 800 K. Making use of first-principles calculations, here we show that the electronic and vibrational properties of both materials are very similar in this phase and, consequently, SnS is also expected to have a high thermoelectric figure of merit at high temperature in its Cmcm phase. In fact, the electronic power factor and lattice thermal conductivity are comparable for both materials, which ensures a similar figure of merit. As in the case of SnSe, the vibrational properties of SnS in the Cmcm phase are far from trivial and are dominated by huge anharmonic effects. Its phonon spectra are strongly renormalized by anharmonicity and the spectral functions of some particular in-plane modes depict anomalous non-lorentzian profiles. Finally, we show that non-perturbative anharmonic effects in the third-order force-constants are crucial in the calculation of the lattice thermal conductivity. Our results motivate new experiments in the high temperature regime to measure the figure of merit of SnS.

Mimicking Chiral Light-Matter Interaction
Creators: name: Nechayev, Sergey
name: Banzer, Peter
Publisher: name: arXiv
Year: 2019
Subjects: subject: Optics (physics.optics)
subject: FOS: Physical sciences

description: We demonstrate that electric-dipole scatterers can mimic chiral light-matter interaction by generating far-field circular polarization upon scattering, even though the optical chirality of the incident field as well as that of the scattered light is zero. The presented effect originates from the fact that electric-dipole scatterers respond selectively only to the incident electric field, which eventually results in depolarization of the transmitted beam and in generation of far-field circular polarization. To experimentally demonstrate this effect we utilize a cylindrical vector beam with spiral polarization and a spherical gold nanoparticle positioned on the optical axis -- the axis of rotational symmetry of the system. Our experiment and a simple theoretical model address the fundamentals of duality symmetry in optics and chiral light-matter interactions, accentuating their richness and ubiquity yet in highly symmetric configurations.

description: We consider the local chirality of near-zero eigenvectors from Wilson-Dirac and clover improved Wilson-Dirac lattice operators as proposed recently by Horváth et al. We studied finer lattices and repaired for the loss of orthogonality due to the non-normality of the Wilson-Dirac matrix. As a result we do see a clear double peak structure on lattices with resolutions higher than 0.1 fm. We found that the lattice artifacts can be considerably reduced by exploiting the biorthogonal system of left and right eigenvectors. We conclude that the dominance of instantons on topological charge fluctuations is not ruled out by local chirality measurements.

Controlling Goos-Hänchen shifts in phosphorene via barrier and well

description: We study the effect of the double potentials (barrier, well) on the Goos-Hänchen (GH) shifts in phosphorene. We determine the solutions of the energy spectrum associated with the five regions that make up our system. By studying the phase shifts, we find that the GH shifts are highly sensitive to the incident energy, the $y$ directional wave vector, the potential heights and widths. To validate our findings, we perform a numerical analysis of the GH shifts as a function of the transmission probability under various conditions. In particular, we observe a consistent pattern in which a positive peak in the GH shift is always followed by a negative valley, a behavior evident at all potential height values. Notably, the energies at which the GH shift changes sign coincide exactly with the points at which transmission drops to zero. In particular, the transmission resonances that occur just before and just after the transmission gap region are strongly correlated with the points at which the GH shift changes sign. This study advances our understanding of how the double potential influences the GH shift behaviors in phosphorene. The ability to fine-tune the GH shifts by changing system parameters suggests potential applications in optical and electronic devices using this two-dimensional material.

description: There is considerable recent interest in the phenomenon of anisotropic electroresistivity of correlated metals. While some interesting work has been done on the iron-based superconducting systems, not much is known for the cuprate materials. Here we study the anisotropy of elastoresistivity for cuprates in the normal state. We present theoretical results for the effect of strain on resistivity, and additionally on the optical weight and local density of states. We use the recently developed extremely strongly correlated Fermi liquid theory in two dimensions, which accounts quantitatively for the unstrained resistivities for three families of single-layer cuprates. The strained hoppings of a tight-binding model are roughly modeled analogously to strained transition metals. The strained resistivity for a two-dimensional $t$-$t'$-$J$ model are then obtained, using the equations developed in recent work. Our quantitative predictions for these quantities have the prospect of experimental tests in the near future, for strongly correlated materials such as the hole-doped and electron-doped high-$T_c$ materials.

description: Results are presented for 170 wastewater treatment works sites (20 per substance in influent, effluent and 36 per substance in river water upstream and downstream of the WwTW discharge) over a period of two years between 2015 and 2017; this comprises data for approximately 3000 samples for effluent and 6000 for river samples taken downstream of effluent discharges. Seasonal trends in contaminant concentrations for several substances are reported. Two clear patterns of seasonal variation are proposed over and above all of the variables associated with environmental data including process technology, dilution and geography. Firstly, variation of riverine concentrations caused by seasonal fluctuations in river flow (sewage flow being relatively consistent) resulting in summer maxima and winter minima. Alternatively, variation is observed that is attributable to the improved performance of wastewater treatment processes under warmer conditions. This leads to the lowest concentrations in autumn when surface water/sewage treatment temperatures tend to peak. Seasonality for trace contaminants is more difficult to characterise than that of sanitary parameters owing to the higher variability in the concentration of the substances of interest. The data also provide an insight into the amplitude of such variations. This makes it possible to assess the likely effects of seasonality and its impact on aquatic life. For example, the existence of seasonality (perhaps due only to dilution effects) might be demonstrated, but the amplitude might be too small in relation to the potential ecotoxicological effects to be of any consequence.

 TYPE SPECIES: Dolichopus griseipennis Stannius, 1831 (as “ Dolicopus Griseipennis Stann. ”), by original designation.
 CURRENT STATUS: Junior synonym of Dolichopus Latreille, 1797 [teste Brooks (2005: 46)].
FAMILY: DOLICHOPODIDAE.
 REMARKS: Rhagoneurus Loew (1864: 346) was listed as an (unjustified) emendation of Ragheneura Rondani, 1856 by Brooks (2005: 47) but, in our opinion, Loew is explicitly proposing a new genus (“I propose for this new genus...”) complete with diagnosis and type species. Loew at the same time misspelled Rondani’s genus as Rhageneura.
