description: Abstract: Nepal, a Himalayan state, has a diverse topography, including cultures, languages, religions, and ethnicities. Yakkha is one of the listed indigenous nationalities of Nepal and mostly live on the eastern hills of the country. It is different from Rai and Limbu in the context of language, culture, and territory. To consider this, the Nepalese government provides a distinct identity to Yakkha although most people are still unaware of Yakkha and ask whether Yakkha is Rai or Limbu. Still, the Yakkha is kept under Rai even on websites and people are confused. Besides, some original Yakkha themselves write Rai, Dewan, and Limbu as their caste. They are also forgetting Yakkha languages and cultures. So, this article attempts to clarify the identity of Yakkha who is living in the eastern hills. There is much research conducted about indigenous communities by national and international researchers, but very little literature is available regarding Yakkha; as a result, the identity of Yakkha is in transition and it is marginalizing. Still, the ethnic organization has been working for 29 years ago but its tasks are not satisfactory. So, this article attempts to clarify the identity of Yakkha, who is living in the eastern hills of Nepal. Moreover, this paper also tries to portray the causes of the marginalization of Yakkha in Nepal. Mainly, this paper is prepared from the data from a field survey conducted in 2014. In-depth interviews, field notes, and field observation were the main methods adopted to collect the data. In addition, the previous study reports, reports of various censuses, books, and research reports were also equally applied to fulfill the research objectives of this paper. Nowadays, in Nepal, various ethnic groups are raising their voices to establish their identity; however, the Yakkha is not so active. That’s why the identity of the Yakkha is marginalized due to internal and external causes. The researcher found that the less practice of speaking Yakkhas` mother tongue by Yakkha themselves, documentation errors, and lack of research works and publications are the main reasons for marginalizing Yakkha in Nepal.

description: Study shows that software developers spend about 19% of their time looking for information in the web during software development and maintenance. Traditional web search forces them to leave the working environment (e.g., IDE) and look for information in the web browser. It also does not consider the context of the problems that the developers search solutions for. The frequent switching between web browser and the IDE is both time-consuming and distracting, and the keyword-based traditional web search often does not help much in problem solving. In this paper, we propose an Eclipse IDE-based web search solution that exploits the APIs provided by three popular web search engines-- Google, Yahoo, Bing and a popular programming Q & A site, Stack Overflow, and captures the content-relevance, context-relevance, popularity and search engine confidence of each candidate result against the encountered programming problems. Experiments with 75 programming errors and exceptions using the proposed approach show that inclusion of different types of context information associated with a given exception can enhance the recommendation accuracy of a given exception. Experiments both with two existing approaches and existing web search engines confirm that our approach can perform better than them in terms of recall, mean precision and other performance measures with little computational cost.

description: Despite various debugging supports of the existing IDEs for programming errors and exceptions, software developers often look at web for working solutions or any up-to-date information. Traditional web search does not consider the context of the problems that they search solutions for, and thus it often does not help much in problem solving. In this paper, we propose a context-aware meta search tool, SurfClipse, that analyzes an encountered exception and its context in the IDE, and recommends not only suitable search queries but also relevant web pages for the exception (and its context). The tool collects results from three popular search engines and a programming Q & A site against the exception in the IDE, refines the results for relevance against the context of the exception, and then ranks them before recommendation. It provides two working modes--interactive and proactive to meet the versatile needs of the developers, and one can browse the result pages using a customized embedded browser provided by the tool.

description: The six Persian Gulf monarchies are home to some of the world’s largest hydrocarbon reserves, and also some of the cheapest energy prices and highest per-capita consumption. Government subsidies based on socio-political objectives have contributed to regime longevity, but they have also stimulated demand for resources comprising the region’s chief export and biggest contributor to GDP. This paper finds that these monarchies – Qatar excepted – face an increasingly acute conflict between maintaining subsidies and sustaining exports. A shift to a higher-cost model of energy provision is underway. The era when primary energy was considered nearly free is being eclipsed by one where new sources of demand are met by more expensive resources. For now, governments have absorbed the increased costs. Consumers have been insulated from higher prices. This counterproductive practice only intensifies the call on exportable resources. The choice for regimes is one of short-term political stability versus longer term economic sustainability. As energy production reaches a plateau, domestic consumption will gradually displace exports. Politically difficult reforms that moderate consumption can therefore extend the longevity of exports, and perhaps, the regimes themselves.

description: While classification of remote sensing images has proven useful to quantify wetland losses, wetland mappers have always faced challenges, such as dealing with variable responses of wetlands to meteorological conditions and the obstruction of ground by the canopy in forested wetlands. In this paper, we investigate the added value of using geomorphological data, namely hillslope geometry (through Dikau shapes) and soil drainage classes, as ancillary datasets to map the evolution of wetland cover over the last 35 years. We developed an object-based image analysis method, through a case study in Quebec. Two sets of land cover scenarios (spring and fall) were generated from Landsat archives for 1978, 1985, 1992, 2001, and 2014. Results show that the global accuracy was improved by 19% to 35% when using the geomorphological data, especially soil drainage classes, confirming that their use as ancillary data significantly contributed to the classification process. However, differences were noted between spring and fall scenarios. The wetland cover of the study watershed decreased by 8%–53% between 1978 and 2014 at the expense of an increase in urban areas. Meanwhile, the agricultural land cover decreased (72%–83%) throughout the study period, while forests, water, and bare soil remained stable.

Monte Carlo Renormalization Group for Systems with Quenched Disorder

description: We extend to quenched disordered systems the variational scheme for real space renormalization group calculations that we recently introduced for homogeneous spin Hamiltonians. When disorder is present our approach gives access to the flow of the renormalized Hamiltonian distribution, from which one can compute the critical exponents if the correlations of the renormalized couplings retain finite range. Key to the variational approach is the bias potential found by minimizing a convex functional in statistical mechanics. This potential reduces dramatically the Monte Carlo relaxation time in large disordered systems. We demonstrate the method with applications to the two-dimensional dilute Ising model, the random transverse field quantum Ising chain, and the random field Ising in two and three dimensional lattices.

description: Electronic density of states (DOS) is a key factor in condensed matter physics and material science that determines the properties of metals. First-principles density-functional theory (DFT) calculations have typically been used to obtain the DOS despite the considerable computation cost. Herein, we report a fast pattern learning method for predicting the DOS patterns of not only bulk structures but also surface structures in multi-component alloy systems by a principal component analysis. Within this framework, we use only four features to define the composition, atomic structure, and surfaces of alloys, which are the d-orbital occupation ratio, coordination number, mixing factor, and the inverse of miller indices. While the DFT method scales as O(N^3) in which N is the number of electrons in the system size, our pattern learning method can scale as O(1) regardless of N. Furthermore, our method provides a pattern similarity of 91~98% compared to DFT calculations. This reveals that our learning method will be an alternative that can break the trade-off relationship between accuracy and speed that is well known in the field of electronic structure calculations.

description: This treatment of power corrections (in a special case of Euclidean asymptotic regimes and vacuum condensates) remains exemplary. Unlike A.Mueller's 1985 "renormalon" paper, this trail-blazing Letter: 1) was based on the correct mechanism of factorization for power corrections (--> comments appended to the main text); 2) used a method (which subsequently became Asymptotic Operation; hep-ph/9703424 and refs. therein) that automatically yields exact diagrammatic formulas for the coefficients of power corrections, which directly allow non-perturbative operator interpretation (without any 'matchings'); 3) did not conjure irrelevant mathematical concepts (Borel summation) nor introduce arbitrary hypotheses ("renormalons") to explain what is clear already from careful analysis of diagrams (coefficients of power corrections are not perturbatively calculable). Incidentally, January 4 is the birthday of Sir Isaac Newton whose example as regards non-invention of arbitrary hypotheses proves so hard for theorists to follow.

description: Synthesis of nanoparticles using biodegradable source is safer and echo-friendly. Here we describe the synthesis of polycrystalline silver nanocrystals using Citrus sinensis acting both as reducing and capping agent. After exposing the silver ions to orange extract, rapid reduction of silver ions led to the formation of stable silver nanocrystals due to the reducing and stabilizing properties of orange fruit juice. The synthesized silver nanocrystals were characterized using various analytical techniques like UV–Vis spectroscopy, XRD, Dynamic Light Scattering (DLS), SEM and TEM. The biochemical activity of the synthesized nanocrystals was studied in the light of affinity to Bovine Serum Albumin using several biophysical methods like absorbance, fluorescence and circular dichroism spectroscopy. Cytotoxic activity of these nanocrystals was also studied against Hep–2 cell line using fluorescence microscopy. It was also found that the synthesized nanocrystals can sense mercuric ion down to 50 µM in presence of a number of cations. Furthermore, we established that the silver nanoparticles can effectively catalyze the reduction of methylene blue by ascorbic acid. The present study will enrich our knowledge on the chemical and biochemical activity of green–synthesized silver nanocrystals.

description: The interaction and binding behavior of excited state intramolecular proton transfer (ESIPT) probe 3-formyl-4-hydroxy benzoic acid (FHBA) with bovine and human serum albumins (BSA and HSA, respectively) was monitored through a series of biophysical techniques including steady state and time-resolved fluorescence as well as molecular docking calculation. The fluorescence emission of FHBA can be tuned from selective excited state species due to its spontaneous association with protein binding sites in a cooperative manner. On the other hand, Stern– Volmer analysis of the tryptophan fluorescence quenching data in presence of FHBA reveals the ligand– protein association constant (Ka) and other thermodynamic parameters like enthalpy (?H) and entropy (?S) change corresponding to the ligand binding process. The results show that FHBA binds into the sub-domain IIA of the proteins in 1:1 stoichiometry with an apparent binding constant value in the range of ∼104 M1. In both the cases, FHBA binds spontaneously with the proteins through entropy driven hydrophobic mechanism, although the interaction with BSA is relatively stronger in comparison with HSA. The fluorescence titration results are corroborated nicely with the supplement experiments like circular dichroism (CD), isothermal titration calorimetry (ITC) and also with the results from molecular docking calculation.

description: We examine the question of whether identity is just a `label' or whether it matters in affecting outcomes, such as education, employment or political orientation, using data on Turkish and ex Yugoslavian second generation immigrants in Austria and Germany. We begin with an empirical investigation of identity formation, with a focus on parental investment in their child's identity, and use this to understand the impact of the child's own identity on own outcomes, a generation later. The results suggest that identity does not have a significant effect on education, employment and political orientation, thus suggesting that a strong ethnic/ religious minority identity does not constrain the second generation or hamper socioeconomic integration.

description: Using the astrometry from the ESA's Gaia mission, previous works have shown that the Milky Way stellar halo is dominated by metal-rich stars on highly eccentric orbits. To shed light on the nature of this prominent halo component, we have analysed 28 Galaxy analogues in the Auriga suite of cosmological hydrodynamics zoom-in simulations. Some three quarters of the Auriga galaxies contain significant components with high radial velocity anisotropy, beta > 0.6. However, only in one third of the hosts do the high-beta stars contribute significantly to the accreted stellar halo overall, similar to what is observed in the Milky Way. For this particular subset we reveal the origin of the dominant stellar halo component with high metallicity, [Fe/H]~-1, and high orbital anisotropy, beta>0.8, by tracing their stars back to the epoch of accretion. It appears that, typically, these stars come from a single dwarf galaxy with a stellar mass of order of 10^9-10^10 Msol that merged around 6-10 Gyr ago, causing a sharp increase in the halo mass. Our study therefore establishes a firm link between the excess of radially anisotropic stellar debris in the Milky Way halo and an ancient head-on collision between the young Milky Way and a massive dwarf galaxy

Resonant two-magnon Raman scattering in parent compounds of high-T$_c$ superconductors.

description: We propose a theory of two-magnon Raman scattering from the insulating parent compounds of high-T$_c$ superconductors, which contains information not only on magnetism, but also on the electronic properties in these materials. We use spin density wave formalism for the Hubbard model, and study diagrammatically the profile of the two-magnon scattering and its intensity dependence on the incoming photon frequency $ω_i$ both for $ω_i \ll U$ and in the resonant regime, in which the energy of the incident photon is close to the gap between conduction and valence bands. In the nonresonant case, we identify the diagrams which contribute to the conventional Loudon-Fleury Hamiltonian. In the resonant regime, where most of the experiments have been done, we find that the dominant contribution to Raman intensity comes from a different diagram, one which allows for a simultaneous vanishing of all three of its denominators (i.e., a triple resonance). We study this diagram in detail and show that the triple resonance, combined with the spin-density-wave dispersion relation for the carriers, explains the unusual features found in the two-magnon profile and in the two-magnon peak intensity dependence on the incoming photon frequency. In particular, our theory predicts a maximum of the two-magnon peak intensity right at the upper edge of the features in the optical data, which has been one of the key experimental puzzles.

description: A carcinogenic risk assessment of polycyclic aromatic hydrocarbons (PAHs) in dietary components was conducted using probabilistic approach from a global perspective. Published monitoring data of PAHs present in foods at different study points across the world were reviewed and collected as their corresponding BaPeq concentrations. These BaPeq concentrations were used to evaluate comprehensive cancer risk for two different age groups (children and adults). Monte Carlo simulation and sensitivity analysis were applied to quantify uncertainties of risk estimation. 95% risk values for food PAHs varies between 5.36E-07 to 1.97E-03 for children and 6.44E-07 to 4.56E-03 for adults. Overall carcinogenic risks of PAHs in food samples from all over the world were mostly in acceptance limits. However, diagnostic ratio analysis confirmed that PAHs contribution by some cooking process like grilling/smoking and industrial/vehicular pollution can respectively affect cooked foods and raw agricultural products. Sensitivity analysis reveals exposure duration (contribution: 45.3% for Children & 54.7% for adults) and food ingestion rate per unit of body mass (contribution: 40.2% for children and 28.5% for adults) as the most influential parameter of the assessment, followed by cancer slope factor for ingestion of BaP. Some specific locations like Prince Island, Tianjin Province and Khyber Pakhtunkhwa Province demand potential strategies of carcinogenic risk management and reduction. The current study is the probable first attempt to provide summed up information on carcinogenic risk of PAHs in dietary components on a global scale.
Symmetry properties of stable solutions of semilinear elliptic equations in unbounded domains

Publisher: name: arXiv

Subjects: subject: Analysis of PDEs (math.AP)

description: We consider stable solutions of a semilinear elliptic equation with homogeneous Neumann boundary conditions. A classical result of Casten, Holland [20] and Matano [44] states that all stable solutions are constant in convex bounded domains. In this paper, we examine whether this result extends to unbounded convex domains. We give a positive answer for stable non-degenerate solutions, and for stable solutions if the domain $Ω$ further satisfies $Ω$ $\cap$ {|x| $\le$ R} = O(R^2), when R $\rightarrow$ +$\infty$. If the domain is a straight cylinder, an additional natural assumption is needed. These results can be seen as an extension to more general domains of some results on De Giorgi's conjecture.As an application, we establish asymptotic symmetries for stable solutions when the domain satisfies a geometric property asymptotically.

description: A structural shift from transaction-based, marginal cost pricing to fee-based service business models often accompanies We emergence of “platform” markets, i.e. multi-sided markets where an intermediary captures the value of the interaction between user groups. The many examples include telecommunications, data storage, cinema, music and media, and the automobile industry. Why not electricity? In this paper, we explore how the electricity supply industry can be conceived of as a platform-mediated, two-sided market and the consequences for pricing. Through two cases, a balancing services provider for smart home energy management systems and an electric vehicle charge manager, we show where a platform entrant could position itself in the retail electricity markets between supply companies and end-users. The drivers of such a transition include increased volatility due to renewable generation, the new complexity of roles for end-users, and the introduction of information and communication technologies. Conceiving of electricity as a platform market where new entrants provide an energy optimisation and management service may stimulate a competitive ecosystem and innovation. We suggest that fee-based pricing would enable the objectives of time-varying pricing to be achieved without adversely affecting the most vulnerable customers.

description: A new indole alkaloid, 17-oxo-19-(Z)-naucline, and six known alkaloids 2–7 were isolated from the branches of Nauclea officinalis. The structure of the new compound 1 was characterised mainly by analysing its physical data including IR, 1 D, 2 D NMR, and HR-ESI-MS. Other compounds were identified by comparisons their data with those reported in the literature. Compound1, 4, 5, 6, 7 showed in vitro anti-inflammatory activity decrease the LPS-stimulated production of nitric oxide in RAW264.7 cell, while all compounds exhibited weak cytotoxicity against human tumour cell lines (LOVO, A549 and HepG2).

description: We review the recent developments in the field of nuclear double beta decay, which is presently an important topic in both nuclear and particle physics. The mechanism of lepton number violation within the neutrinoless double beta decay is discussed in context of the problem of neutrino mixing and the R-parity violating supersymmetric extensions of the Standard model. The problem of reliable determination of the nuclear matrix elements governing both two-neutrino and neutrinoless modes of the double beta decay is addressed. The validity of different approximation schemes in the considered nuclear structure studies is analyzed and the role of the Pauli exclusion principle for a correct treatment of nuclear matrix elements is emphasized. The constraints on different lepton number violating parameters like effective electron neutrino mass, effective right-handed weak interaction parameters, effective Majoron coupling constant and R-parity violating SUSY parameters are derived from the best presently available experimental limits on the half life of neutrinoless mode of this process.

description: We report ground-state calculations and Monte Carlo simulations for a lattice-gas model of the underpotential deposition of copper on Au(111) in sulfate-containing electrolytes. In a potential range of approximately 100$\sim$150 mV, this system exhibits a $(\sqrt3\!\times\!\sqrt3)$ mixed phase with 2/3 monolayer (ML) copper and 1/3 ML sulfate. Our simulation results agree well with experimental results and with other theoretical work.

Regulatory Inefficiency

description: In the EU, several governments have introduced or are contemplating a capacity mechanism to ensure adequate investment in generation capacity. Previous research has focused on the impacts of capacity mechanisms on installed capacity and cost to consumers in case of efficient regulation. By contrast we find that the choice between capacity mechanisms may be influenced by the extent of regulatory errors as well as whether the mechanisms evaluated from the perspective of consumer cost or from a welfare perspective.

description: To define the prevalence of medical eye disease diagnoses among children enrolled in commercial insurance plans in the United States and to evaluate differences among groups based on the US census region, race/ethnicity, and familial net worth. : Retrospective study of de-identified claims data from the OptumLab® Data Warehouse (OLDW) between 2007 and 2018. All children (<19 years) in the OLDW with coverage were studied and those with a claim for a significant eye disease (strabismus, amblyopia, nystagmus or structural eye disorders) with minimum 6-months follow-up were studied. Baseline characteristics were extracted for the calculation of eye disease prevalence, including age, sex, race/ethnicity, region of residence, and family net worth. The prevalence of each type of eye disease was calculated among all children and by baseline characteristics. : 10,759,066 children met the study criteria. The presence of any significant eye diagnosis was 6.7%. Disease was diagnosed more often in whites (6.9%) than blacks (5.6%) and Hispanics (5.9%). The most common eye disease diagnosed was strabismus (3.2%) followed by amblyopia (1.5%). In the North-East region, there was a 10.6% prevalence of any significant eye disease diagnosis, whereas in the Mid-West, it was 7.4% followed by the South and West (5.9% and 5.3%, respectively) (p < .001). There was an increase in eye disease diagnoses with increasing income (5.5% in<$25,000 and 9.4% in >$500,000 household net worth groups, p > .001). : Diagnosis of significant eye diseases is relatively common in American children. The most common medical eye disease diagnosis is strabismus. Prevalence of eye disease diagnosis from claims data varies between geographical regions and different income groups. This may reflect differences in healthcare utilization rather than true disease prevalence.

description: NuTeV is a neutrino-nucleon deep inelastic scattering experiment at Fermilab. The NuTeV detector is a traditional heavy target neutrino detector which consists of an iron/liquid scintillator sampling calorimeter followed by a muon spectrometer. The calorimeter response to hadrons, muons and electrons has been measured in an in situ calibration beam over the energy range from 4.5 to 190 GeV. The small non-linearity of the response to hadrons is compared to the expectation from the measured ratio of responses between electrons and hadrons combined with the energy dependence of the fractional electromagnetic energy deposition in the form of neutral pions in hadronic showers $f_{π^{0}}(E_π)$. The predictions use $f_{π^{0}}(E_π)$ from the Monte Carlo simulations by GHEISHA, GFLUKA and GCALOR and also from the parameterizations of Wigmans and Groom. In addition, a study based on the NuTeV hadron calibration data of the effectiveness of a thin calorimeter is presented. The results of this study have important consequences for the energy resolution of calorimeters used in other applications; for example, measuring the cosmic ray flux in space or with balloon-based experiments.

"Plane" electromagnetic wave in spatially flat Friedman universe

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: The electromagnetic theory is, to a large extend, metric independent. Before the metric is introduced, it is called premetric electrodynamics. Metric enters the constitutive relation. We consider this relation for the Friedman model of an expanding Universe and find that the magnitudes of the field quantities depend on the scale factor. This factor, however, does not enter the permeability and permittivity of the vacuum. A spatially uniform electromagnetic field is obtained for spatially flat metric. Then plane electromagnetic wave is found with uniform field playing the role of amplitudes. It turns out that the magnitudes of the frequency and the wave covector depend on the scale factor determining the redshift, but the phase velocity of the wave is constant.
