description: Figure S10. Quintile chromatin configuration at human bivalent promoters. Left panel: As an alternative to k-means clustering we divided the data underlying Fig. S8 into H3K27me3:H3K4me3 quintiles determined by the ChIPseq signal ratio which emphasises the difference between Q5 and Q4 to Q1 inclusive. Q5 is consistent with hiBiv and Q4 to Q1 account for loBiv. Right panel: we performed a similar quintile division of the data underlying Fig. 6a. Q5 quintile (which is most related to hiBiv) shows most H3K27me3-sensitivity to DNA hypomethylation comparing HMEC to HCC1954/MCF7 and colon to HCT116. In contrast, Q4 to Q1 show an attenuated H3K27me3-response to DNA hypomethylation.

 The Lithoglyptinae has been proposed to accommodate Lithoglyptes s.l. and Balanodytes. In the following we will propose that the former be subdivided into Lithoglyptes s.s. and two new genera, Auritoglyptes gen. nov. and Armatoglyptes gen. nov., the diagnostic characteristics of which accompany the discussion of each genus.
(N.B., the opening to the mantle cavity in acrothoracicans is guarded by “apertural lips”, but since they consist of a pair of hard chitinous bars and a comb collar, they are effectively an operculum and will be referred to as such herein).

Quark-Hadron Duality and Scaling in Reduced QCD

description: We introduce a generalization of 1+1 dimensional large Nc QCD, which we refer to as ``reduced'' QCD, or rQCD. In this model gluons and quark momenta live in 1+1 dimensions only, but the quark spin and all other particles (leptons, and the photon) live in the full 1+3 dimensions. The bound states of quarks and antiquarks are identical to those originally described by 't Hooft (except that there are new transversely polarized states previously excluded), so the model is exactly soluable. However, significant differences arise when the model is applied to electromagnetic interactions. After reviewing the strongly interacting sector of the theory, we discuss deep inelastic scattering (DIS) in this model, and show that the new states with transverse polarization give the Callan-Gross relation and remove the pathological features of the original 1+1 dimensional description. We conclude that rQCD gives a satisfactory description of the phenomenology and provides a deep understanding of both duality and DIS.

description: A soft X-ray excess above the 2-10 keV power law extrapolation is generally observed in AGN X-ray spectra. Presently there are two competitive models to explain it: blurred ionized reflection and warm Comptonisation. In the latter case, observations suggest a corona temperature $\sim$ 1 keV and a corona optical depth $\sim$ 10. Moreover, radiative constraints from spectral fits with Comptonisation models suggest that most of the accretion power should be released in the warm corona. The disk below is basically non-dissipative, radiating only the reprocessed emission from the corona. The true radiative properties of such a warm and optically thick plasma are not well-known, however. For instance, the importance of the Comptonisation process, the potential presence of strong absorption/emission features or the spectral shape of the output spectrum have been studied only very recently. We present in this paper simulations of warm and optically thick coronae using the TITAN radiative transfer code coupled with the NOAR Monte-Carlo code, the latter fully accounting for Compton scattering of continuum and lines. Illumination from above by a hard X-ray emission and from below by an optically thick accretion disk is taken into account as well as (uniform) internal heating. Our simulations show that for a large part of the parameter space, the warm corona with sufficient internal mechanical heating is dominated by Compton cooling and neither strong absorption nor emission lines are present in the outgoing spectra. In a smaller part of the parameter space, the calculated emission agrees with the spectral shape of the observed soft X-ray excess. Remarkably, this also corresponds to the conditions of radiative equilibrium of an extended warm corona covering almost entirely a non-dissipative accretion disk. These results confirm the warm Comptonisation as a valuable model for the soft X-ray excess.

description: Figure S9. Gene ontology analysis of human hiBiv and loBiv associated genes. Gorilla and REViGO tools were coupled to define and reduce redundancy for enriched gene ontology terms in human hiBiv and loBiv compared to all genes. Colour coding of the scatterplots are related to the log10 of the enriched p-values estimated by Gorilla. Area of circular plotted data is proportional to the number of genes enriched in each GO term. Redundant GO terms are reduced using the method of ‘semantic similarity’ measurement which is analogous to hierarchical clustering methods. This involves generating clusters of similar GO terms based on close p-values and whether one term is a child node of the other term [76].

Dos décadas después, en la presentación de la exposición Correspondencias Erice – Kiarostami, el cineasta utilizaba entonces el concepto «fraternidad entre lo real y la ficción» para describir su manera de entender la experiencia cinematográfica. Si bien El sol del membrillo (1992) es precursor de un nuevo cine contemporáneo basado en esa fraternidad (Monterrubio, 2018), la reflexión ensayística se convierte en forma fílmica en esta correspondencia entre los cineastas y, muy especialmente, en La Morte Rouge (soliloquio) (2006).

Exact three spin correlation function relations for the square and the honeycomb Ising lattices

Publisher: name: arXiv

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: In this work, the order parameter and the two-site correlation functions are expressed properly using the decimation transformation process in the presence of an external field so that their applications lead to some significant physical results. Indeed, their applications produce or reproduce some relevant and important results which were included in cumbersome mathematics in the previous studies, if not in a form impossible to understand. The average magnetization or the order parameter $ $ is expressed as $= $. Here, $κ$ is the coupling strength, $z$ is the number of nearest neighbors. $σ_{0,i}$ denotes the central spin at the $i^{th}$ site, while $σ_{l,i}$, $l=1,2,\dots,z$ are the nearest neighbor spins around the central spin. $H$ is the normalized external magnetic field. We show that the application of this relation to the 1D Ising model reproduces readily the previously obtained exact results in the absence of an external field. Furthermore, the three-site correlation functions of square and honeycomb lattices of the form $$ are analytically obtained. One finds that the three-site correlation functions are equal to $f(κ)\!\!$. Here $f(κ)$ depends on the lattice types and is an analytic function of coupling constant. This result indicates that the critical properties of three-site correlation functions of those lattices are the same as the corresponding order parameters $$ of those lattices. This will mean that the uniqueness of the average magnetization as an order parameter is questionable. ...

description: KEY FINDINGS: Landscape positions dictates fertilizer need. Distinct features in terms of slope, water holding capacity and inherent soil fertility determine the amount and type of fertilizer to be used (ICRISAT, 2017). This needs to be understood and appreciated by farmers, extension agents and those involved in the design and implementation of farmer productivity programs, particularly those involving fertilizer. Soil rooting depth is critical. Having 10 -20 cm topsoil loss could decrease yield of corn even with added inorganic fertilizer. Complete total crop failure could occur (see figure 1) where, with increasing depth of soil loss, yields declined drastically even with added fertilizer at recommended rate for the area. Limitations within a soil profile will reduce its effective rooting depth affecting anchorage, growth and development. (Agada 2018 unpublished Ph.D. Dissertation). Rainfall characteristics such as high rainfall amounts, intensity and drop size will lead to loss of soil nutrients (weather added as organic or inorganic amendments) and loss of soil particles (Obi and Salako 1995; Agada et al, 2016) furthering the vicious cycle of erosion. Thus with varied environmental conditions across the country, real-time nutrient management strategies are necessary (Theriault et al, 2018). There is an urgent need to educate farmers on fertilizer management practice. This involves information on fertilizer placement and timing, soil depth, soil types, slope positions and other agronomic/ management practices. With increased variation in climate, changing, or modifying hitherto farmer knowledge of certain agronomic practices in order to improve agricultural productivity is key (Delgado et al, 2011).

description: Recently a significant progress in matching the anomalous dimensions of certain class of operators in N=4 SYM theory and rotating strings was made. The correspondence was established mainly using Bethe ansatz technique applied to the spin s Heisenberg model. In a recent paper Kruczenski (hep-th/0311203) suggested to solve the Heisenberg model by using of sigme model approach. In this paper we generalize the solutions obtained by Kruczenski and comment on the dual string theory. It turns out that our solutions are related to the so called Neumann-Rosochatius integrable system. We comment on the spin chain solutions and on the string/gauge theory correspondence.

description: Recent demonstrations of magnetic ordering and spin transport in two-dimensional heterostructures have opened research venues in these material systems. In order to control and enhance the related physical phenomena, quantitative descriptions linking experimental observations to atomic details must be produced. Here we combine first principles and quantum ballistic transport calculations to shed important insights from an atomistic viewpoint on the underlying mechanisms governing spin transport in graphene/CrI$_3$ junctions. Descriptions of the electronic structure reveal that tunneling is the dominant transport mechanism in these heterostructures and help differentiate intermediate metamagnetic states present in the switching process. We find that quantum confinement and layer-layer interactions are key to describing transport in these two-dimensional systems. Ballistic transport calculations further support these findings and yield magnetoresistance values in remarkable agreement with experiments. The short width of these barriers limits analysis solely based on the bulk complex band structure often employed in the description of magnetic tunnel junctions. Our work devises mechanisms to attain larger tunneling magnetoresistances, proving valuable to the advancement of spin valves in layered heterostructures.

description: We review the development and practical uses of a generalized Maupertuis least action principle in classical mechanics, in which the action is varied under the constraint of fixed mean energy for the trial trajectory. The original Maupertuis (Euler-Lagrange) principle constrains the energy at every point along the trajectory. The generalized Maupertuis principle is equivalent to Hamilton's principle. Reciprocal principles are also derived for both the generalized Maupertuis and the Hamilton principles. The Reciprocal Maupertuis Principle is the classical limit of Schrödinger's variational principle of wave mechanics, and is also very useful to solve practical problems in both classical and semiclassical mechanics, in complete analogy with the quantum Rayleigh-Ritz method. Classical, semiclassical and quantum variational calculations are carried out for a number of systems, and the results are compared. Pedagogical as well as research problems are used as examples, which include nonconservative as well as relativistic systems.

description: We explore dark matter in the Finely Tuned Minimal Supersymmetric Standard model recently proposed by Arkani-Hamed and Dimopoulos. Relative to the MSSM, there are fewer particles at freeze-out, so the calculation of the relic abundance simplifies. Similarly, the predictions for direct detection of the dark matter sharpen. There is a large region of mixed bino--higgsino dark matter where the lightest supersymmetric particle will be accessible at both the LHC and future direct detection experiments, allowing for a conclusive identification of the dark matter particle. Typical dark matter-nucleon cross sections are 10^{-45}-10^{-44} cm^{2}. This model also possesses a novel region where the dark matter annihilates via an s-channel Higgs boson resonance.

We show that a suitable iterated suspension of F(M,k) is a homotopy invariant of M. The number of suspensions we require depends on three parameters: the number of points k, the dimension of M and the connectivity of M. Our proof uses a mixture of Poincare embedding theory and fiberwise algebraic topology.

description: The paper presents an alternative method of sustainable intensification (SI) measurement. It is based on efficiency analysis using DEA method, Malmquist TFP index and Euclidean and angular distance measurements. The proposed measure makes it possible to determine the dynamics of the process of sustainable intensification, taking into account the base level of economic and eco-efficiency. Applied solution partially eliminates the problem of weighing the various dimensions of sustainable development. The method was used to measure SI in the European Union countries in 2005-2013. Obtained results confirm the presence of this process in most countries and on average in the whole EU. It was particularly fast among the countries of Central and Eastern Europe and among the Scandinavian countries. Changes that were not in line with the SI concept, occurred in the Benelux countries and in the British Isles, where environmental productivity improved, diminishing economic productivity. / Synopsis.

Proponowany miernik pozwala określić dynamikę procesu zrównoważonej intensyfikacji, z uwzględnieniem pierwotnego poziomu efektywności nakładów ekonomicznych i ekoefektywności. Zastosowane rozwiązanie pozwala częściowo zniwelować problem ważenia poszczególnych wymiarów zrównoważonego rozwoju. Metodę zastosowano do pomiaru SI w krajach Unii Europejskiej w latach 2005-2013. Uzyskane wyniki potwierdzają występowanie tego procesu w większości krajów oraz przeciętnie w całej UE. Szczególnie szybko postępował on wśród krajów Europy środkowo-wschodniej oraz wśród krajów skandynawskich. Zmiany niezgodne z koncepcją zrównoważonej intensyfikacji postępowały natomiast w krajach Beneluksu oraz na Wyspach Brytyjskich, gdzie następowała poprawa produktywności środowiskowej, kosztem produktywności nakładów ekonomicznych.

A Transition in the Accretion Properties of Radio-Loud Active Nuclei

description: We present evidence for the presence of a transition in the accretion properties of radio-loud sources. For a sample of radio galaxies and radio-loud quasars, selected based on their extended radio properties, the accretion rate is estimated from the black hole mass and nuclear luminosity. The inferred distribution is bimodal, with paucity of sources at accretion rates, in Eddington units, of order ~ 10^{-2} - assuming a radiative efficiency of 10 per cent - and possibly spanning one-two orders of magnitude. Selection biases are unlikely to be responsible for such behavior; we discuss possible physical explanations, including a fast transition to low accretion rates, a change in the accretion mode/actual accretion rate/radiative efficiency, the lack of stable disc solutions at intermediate accretion rates or the inefficiency of the jet formation processes in geometrically thin flows. This transition might be analogous to spectral states (and jet) transitions in black hole binary systems.

description: This paper presents a theoretical study of the phenomenon of acoustic imaging by sonic crystals, which are made of two-dimensional regular arrays of rigid cylinders placed in parallel in air. The scattering of acoustic waves is computed using the standard multiple scattering theory, and the band structures are computed by the plane-wave expansion method. It is shown that properly arranged arrays not only can behave as acoustic lenses, but also the focusing effect can be well described by Lensmaker's formula. Possible applications are also discussed.

description: Semiconductor nanowire (NW) lasers are a promising technology for the realisation of coherent optical sources with extremely small footprint. To fully realize their potential as building blocks in on-chip photonic systems, scalable methods are required for dealing with large populations of inhomogeneous devices that are typically randomly distributed on host substrates. In this work two complementary, high-throughput techniques are combined: the characterisation of nanowire laser populations using automated optical microscopy, and a high accuracy transfer printing process with automatic device spatial registration and transfer. In this work a population of NW lasers is characterised, binned by threshold energy density and subsequently printed in arrays onto a secondary substrate. Statistical analysis of the transferred and control devices show that the transfer process does not incur measurable laser damage and the threshold binning can be maintained. Analysis is provided on the threshold and mode spectra of the device populations to investigate the potential for using NW lasers for integrated systems fabrication.

description: We give necessary and sufficient conditions of infinite determinacy for smooth function germs whose critical locus contains a given set. This set is assumed to be the zero variety X of some analytic map germ having maximal rank on a dense subset of X.

description: We report production of nanostructured carbon foam by a high-repetition-rate, high-power laser ablation of glassy carbon in Ar atmosphere. A combination of characterization techniques revealed that the system contains both sp2 and sp3 bonded carbon atoms. The material is a novel form of carbon in which graphite-like sheets fill space at very low density due to strong hyperbolic curvature, as proposed for ?schwarzite?. The foam exhibits ferromagnetic-like behaviour up to 90 K, with a narrow hysteresis curve and a high saturation magnetization. Such magnetic properties are very unusual for a carbon allotrope. Detailed analysis excludes impurities as the origin of the magnetic signal. We postulate that localized unpaired spins occur because of topological and bonding defects associated with the sheet curvature, and that these spins are stabilized due to the steric protection offered by the convoluted sheets.

description: Food trade is an important element of the global economy. As far as the European Union is concerned, it has sufficient resources to cover the EU population's demand for food, and it can export and exchange its own excess production for other products or services with other countries. However, Japan does not appear to be a significant partner in terms of food imports and exports. The aim of the study is to present a detailed analysis of the volume of food exports and imports according to the SITC and HS nomenclature and the perspectives for the development of mutual cooperation between the European Union and Japan. / Synopsis. Ważnym zagadnieniem jest handel żywnością w skali świata. Jeśli chodzi o Unię Europejską to posiada ona odpowiednie zasoby wystarczające na pokrycie zapotrzebowania ludności UE na żywność, nadwyżki produkcji własnej może eksportować i wymieniać na inne produkty bądź usługi z innymi krajami. Natomiast egzotyczny dla Europejczyków azjatycki kraj, jakim jest Japonia wydaje się nie być istotnym partnerem pod względem wymiany handlowej żywnością. Celem opracowania jest zaprezentowanie dokładnej analizy wielkości eksportu i importu żywności według nomenklatury SITC oraz HS oraz perspektyw rozwoju wzajemnej współpracy między Unią Europejską a Japonią.

description: We study triatomic systems in the regime of large negative scattering lengths which may be more favorable for the formation of condensed trimers in trapped ultracold monoatomic gases as the competition with the weakly bound dimers is absent. The manipulation of the scattering length can turn an excited weakly bound Efimov trimer into a continuum resonance. Its energy and width are described by universal scaling functions written in terms of the scattering length and the binding energy, $B_3$, of the shallowest triatomic molecule. For $a^{-1}

description: The aim of the work was simulations of soil organic carbon balances as well as absorption and emission of greenhouse gases (CO2, CH4, N2O) to characterize the mitigation potential of climate change in agricultural use of arable land. Simulations were performed using the DNDC model for voivodships and Poland using a twenty-year series of meteorological data. It was found that the plow cultivation system with the harvest residue (a) will cause in Poland a net emission of these gases amounting to 0.203 t CO2 eq∙ha-1∙y-1. On the other hand, the reduced tillage system leaving crop residues on the field (b) and the tillage system with the regular application of manure and harvest residues (c) will absorb CO2 in amounts: 1.225 and 0.172 t CO2 eq∙ha-1∙y-1 respectively. The obtained results suggest that in the medium-term (20 years) the studied cultivation systems may be recognized as practices mitigating climate change. The use of cultivation systems in the desired proportion in relation to the area of arable land in Poland could give an average greenhouse gas absorption of 0.556 t CO2 eq∙ha-1∙y-1. / Synopsis. Celem pracy były symulacje uproszczonego bilansu węgla oraz pochłaniania i emisji gazów cieplarnianych (CO2, CH4, N2O) dla scharakteryzowania potencjału mitygacji zmian klimatu w rolniczym użytkowaniu gruntów ornych. Symulacje wykonywano przy użyciu modelu DNDC dla województw i Polski z użyciem dwudziestoletnich serii danych meteorologicznych. Stwierdzono, że system uprawy płużnej ze zbiorem resztek pożniwnych (a) powodować będzie w Polsce emisję netto tych gazów wynoszącą 0,203 t CO2 ekw. ∙ ha-1 ∙ r-1. Natomiast system uprawy uproszczonej z pozostawieniem na polu resztek pożniwnych (b) oraz system uprawy płużnej z regularnym stosowaniem obornika i zbiorem resztek pożniwnych (c) pochłaniać będą CO2 w ilościach wynoszących odpowiednio: 1,225 i 0,172 t CO2 ekw. ∙ ha-1 ∙ r-1. Uzyskane wyniki sugerują, że w perspektywie średnioterminowej (20 lat), badane systemy uprawy mogą być uznane za praktyki mitygujące zmiany klimatu. Zastosowanie systemów uprawy w pożądanej proporcji w stosunku do areału gruntów ornych w Polsce mogłoby pozwolić na średnie pochłanianie gazów cieplarnianych rzędu 0,556 t CO2 ekw.∙ha-1∙r-1.

description: A simple analytical model for modeling the evolution of the 2020 COVID-19 pandemic is presented. The model is based on the numerical solution of the widely used Susceptible-Infectious-Removed (SIR) populations model for describing epidemics. We consider an expanded version of the original Kermack-McKendrick model, which includes a decaying value of the parameter $β$ (the effective contact rate) due to externally imposed conditions, to which we refer as the forced-SIR (FSIR) model. We introduce an approximate analytical solution to the differential equations that represent the FSIR model which gives very reasonable fits to real data for a number of countries over a period of 100 days (from the first onset of exponential increase, in China). The proposed model contains 3 adjustable parameters which are obtained by fitting actual data (up to April 28, 2020). We analyze these results to infer the physical meaning of the parameters involved. We use the model to make predictions about the total expected number of infections in each country as well as the date when the number of infections will have reached 99% of this total. We also compare key findings of the model with recently reported results on the high contagiousness and rapid spread of the disease.

description: In self-interacting scalar field theories kinetic expansion is an alternative way of calculating the generating functional for Green's functions where the zeroth order non-Gaussian path integral becomes diagonal in x-space and reduces to the product of an ordinary integral at each point which can be evaluated exactly. We discuss how to deal with such functional integrals and propose a new perturbative expansion scheme which combines the elements of the kinetic expansion with that of usual perturbation theory. It is then shown that, when the cutoff dependent bare parameters in the potential are fixed to have a well defined non-Gaussian path integral without the kinetic term, the theory becomes trivial in the continuum limit.

description: The field of magnetic resonance imaging with hyperpolarized contrast agents is rapidly expanding, and parahydrogen-induced polarization (PHIP) is emerging as an inexpensive and easy-to-implement method for generating the required hyperpolarized biomolecules. Hydrogenative PHIP delivers hyperpolarized proton spin order to a substrate via chemical addition of H2 in the spin-singlet state, but prior to imaging it is typically necessary to transfer the proton polarization to a heteronucleus (usually 13C) in the molecule. Adiabatic ultralow magnetic field manipulations can be used to induce the polarization transfer, but this is necessarily a slow process, which is undesirable since the spins continually relax back to thermal equilibrium. Here we demonstrate constant-adiabaticity field cycling and field sweeping for optimal polarization transfer on a model AA$'$X spin system, [1-13C]fumarate. We introduce a method for calculating constant-adiabaticity magnetic field ramps and demonstrate that they enable much faster spin-order conversion as compared to linear ramps used before. The present method can thus be utilized to manipulate nonthermal order in heteronuclear spin systems.

description: We demonstrate various regimes of synchronization in systems of two coupled cavity soliton-based Kerr frequency combs. We show sub-harmonic, harmonic and harmonic-ratio synchronization of coupled microresonators, and reveal their dynamics in the form of Arnold tongues, structures that are ubiquitous in nonlinear dynamical systems. Our experimental results are well corroborated by numerical simulations based on coupled Lugiato-Lefever equations. This study illustrates the newfound degree of flexibility in synchronizing Kerr combs across a wide range of comb spacings and could find applications in time and frequency metrology, spectroscopy, microwave photonics, optical communications, and astronomy.
