description: We find that a bipartite quantum state is entangled if and only if it is quantum coherent with respect to complete bases of states in the corresponding system that are distinguishable under local quantum operations and classical communication. The corresponding minimal quantum coherence is the entanglement of formation. Connections to the relative entropy of entanglement and quantum coherence, and generalizations to the multiparty case are also considered.

description: Family farming is not only a business, but also a lifestyle where insistence on independency, decision-making and rural area is strong. Therefore, focusing on this issue has prior importance in context of rural development and agriculture. During the research the main question was how farmers from Karcag considered family farming situation. What do they think the greatest advantages and disadvantages of a family farm are? What does their effectiveness depend on? How much is it worth working in family farming? How attractive is this form of business to the young? Under what conditions may family farming provide secure future prospects? On this basis family farming had become an approved form of business. Type of activity and scale of production have significant impacts on the efficiency in farming. The current grant system may not be sufficient to the stabilization and development of family farms; therefore, family farming under the current agricultural policy is not too enticing to the young.
Production of Pseudoscalar Mesons

description: Experiments that study the hadronic and electromagnetic production of the pseudoscalar mesons -- pions, etas and kaons, contribute to our knowledge of the properties of baryon and hyperon resonances. Fixed-target programs at hadronic facilities such as BNL-AGS have been phased out. However, the availability of modern experimental facilities with pseudo-monochromatic or tagged medium-energy photon beams at GRAAL, SPring-8, Bonn, Mainz, and Jefferson Lab, together with LEGS, Max-Lab, and HIGS at lower energies, are beginning to produce high-quality results. These new data have smaller statistical uncertainties and better understood systematic uncertainties, than those obtained at the older bremsstrahlung facilities, for measurements of differential and integrated cross sections, as well as polarization and asymmetry. Experimental results are compared with the predictions of QCD-based approaches, such as the lattice-gauge calculations of baryon properties, and Chiral Perturbation Theory applied to threshold photoproduction, and are essential to the performance of Partial-Wave Analyses (PWA). These PWA studies are less model dependent than in the past, and are used in coupled-channels calculations that incorporate unitarity dynamically, and combine results from hadronic reaction channels with electromagnetic processes. This approach is necessary to extract resonance properties and may lead to the discovery of the "missing resonances" predicted by a number of different QCD-inspired calculations. We discuss recent experimental and phenomenological results for single and double pseudoscalar meson hadronic and photoproduction channels with emphasis on the JLab Hall B and the BNL/AGS Crystal Ball programs.

For the considered additive noise perturbation of such systems, we show the long time behavior of the energy and quadratic Casimirs for the exact solution. We then propose and analyze a drift-preserving splitting scheme for such problems with the following properties: exact drift preservation of energy and quadratic Casimirs, mean-square order of convergence one, weak order of convergence two. These properties are illustrated with numerical experiments.

description: We consider the decay of the Higgs boson to W$^{+}$ W$^{-}$ at a proposed Large Hadron Electron Collider and determine the likelihood of detecting a signal for the Higgs mass from its decay product W jets by imposing cuts to select candidate jet pairs and optimizing the value of the angular separation $ΔR$. It was found that at the LHeC experiment (CM energy $\sqrt{s}=1.3$ TeV and luminosity of 100 fb$^{-1}$ per year), the highest efficiency is obtained with $ΔR = 0.4$, along with a selection scheme of $|Δη| <1, 1010$ GeV: this led to an efficiency between $7.1 - 7.5 \%$ for finding the invariant 4-jet mass in a mass region $<140$ GeV. Under signal-to-background comparison, the signal showed a $3.8 σ$ excess compared to the charged current W$^{-}$ background.

description: We show that the direct Urca process of neutrino emission is allowed in two possible phases of nonspherical nuclei (inverse cylinders and inverse spheres) in the mantle of a neutron star near the crust-core interface. The process is open because neutrons and protons move in a periodic potential created by inhomogeneous nuclear structures. In this way the nucleons acquire large quasimomenta needed to satisfy momentum-conservation in the neutrino reaction. The appropriate neutrino emissivity in a nonsuperfluid matter is about 2--3 orders of magnitude higher than the emissivity of the modified Urca process in the stellar core. The process may noticeably accelerate the cooling of low-mass neutron stars.

Über Grundwasser-Zufluß und Abfluß-Retention von Hochmooren
Upon Groundwater Influx and Runoff Retention of Raised Bogs
Creators: name: Eggelsmann, Rudolf
Publisher: name: FID GEO
Year: 1984

description: Als Beispiel für ein Hochmoor mit Grundwasser-Zufluß ist das "Große Moor bei Gifhorn" ausgewählt. Es wird nachgewiesen, daß ein vorhandener Grundwasserstrom im Sanduntergrund unter dem Moor nicht nennenswert zur Wasserversorgung der Hochmoor—Vegetation beiträgt, weil die Kapillarität der stark zersetzten Hochmoortorfe außerordentlich gering ist. Zahlreiche Hochmoore Nordwesteuropas wiesen früher bekanntlich im Urzustand Oberflächen-Rüllen (Erosionsrinnen) auf, die durch Hochwasser-Abfluß entstanden sind. Daraus kann man unschwer ableiten, daß solche Hochmoore keine nennenswerte Abfluß-Retention gehabt haben, obgleich aus dieser Zeit keine zahlenmäßigen Abflußdaten vorliegen. Synchrone Niederschlags-‚ Grund-/Stauwasser- und Abflußregistrierungen aus jüngster Zeit lassen dies ebenfalls erkennen.
description: The "Große Moor" near Gifhorn (Lower Saxony) has been selected as an example for a raised bog with groundwater influx. It has been shown that an existing groundwater influx into the sand subsoil (below the peatland) does not contribute to the water supply of the raised-bog vegetation, because the capillarity of the highly decomposed raised-bog peat is extremely small. It is well known that numerous raised bogs in northwest Europe exhibited rills at their surface(erosion grooves) caused by high runoff peaks. Therefrom it can be derived without difficulties that such raised bogs did not have any runoff retention worth mentioning. This is also confirmed by recent synchromesh records of rainfall, groundwater and stagnant water and runoff.

The investigations in Jel’nia are part of an investigation scheme in the peatlands and mires of Belarus to work out vegetation forms that indicate mean water level fluctuations (cf. vegetation forms, KOSKA et al. 2001) and connect them with currently undergoing greenhouse gas measurements in Belarus (THIELE et al. 2009) in order to use them later as indicator for greenhouse gas emissions (COUWENBERG et al. 2008, COUWENBERG et al. 2010 in revision). The system of established transects can also serve as a base for long-term monitoring of the results of rewetting activities of local Non-Governmental Organisations and nature conservation administrations.

description: We use the multifractal formalism to describe the effects of dissipation on Lagrangian velocity statistics in turbulent flows. We analyze high Reynolds number experiments and direct numerical simulation (DNS) data. We show that this approach reproduces the shape evolution of velocity increment probability density functions (PDF) from Gaussian to stretched exponentials as the time lag decreases from integral to dissipative time scales. A quantitative understanding of the departure from scaling exhibited by the magnitude cumulants, early in the inertial range, is obtained with a free parameter function D(h) which plays the role of the singularity spectrum in the asymptotic limit of infinite Reynolds number. We observe that numerical and experimental data are accurately described by a unique quadratic D(h) spectrum which is found to extend from $h_{min} \approx 0.18$ to $h_{max} \approx 1$, as the signature of the highly intermittent nature of Lagrangian velocity fluctuations.

Massenverlust und Klimarelevanz von Moorböden durch Nutzung, am Beispiel des Großen Uchter Moores
Mass-loss and relevance to climate change of bogs as a consequence of utilization using the example of the Great Moor of Uchte

Publisher: name: FID GEO
Year: 2010

description: Abstract: In the Great Uchter Moor during a period of 50 years, from 1959 to 2008, the annual carbon dioxide (CO2) emissions for the different uses of the moors can be deducted from the differences of the mightiness of the peat. Therefore the values have to be reduced from the part of settling. In the time of 1959 to 2058 the various use classes were assigned to appropriate emission factors and possible scenarios for the behaviour of greenhouse gas emissions over the past 50 years and in the next 25 to 50 years have been developed. In summary, it shows an overall picture of the climate-relevant behaviour of a large lower bog in Lower Saxony over a period of one hundred years. The Great Moor of Uchte is quite typical for Lower Saxony. A transfer of the data to the scale of Lower Saxony fails at the moment because of the lack of data bases, in particular to the stratigraphy.

Für die Zeit von 1959 bis 2058 wurden denkbare Szenarien der Moorentwicklung angenommen und daraus die Entwicklung der Treibhausgasemissionen in den kommenden 25 bis 50 Jahren prognostiziert. Zusammenfassend ergibt sich ein Gesamtbild des klimarelevanten Verhaltens eines großen niedersächsischen Hochmoores über 100 Jahre. Das Große Moor bei Uchte ist, einschließlich seiner Nutzungen, ein typisches Moor Niedersachsens. Eine Übertragung unserer Daten auf Niedersachsen scheitert jedoch an mangelnden Datengrundlagen, insbesondere zur Stratigraphie.

description: Purpose: Optical Coherence Tomography Angiography (OCT-A) permits visualization of the changes to the retinal circulation due to diabetic retinopathy (DR), a microvascular complication of diabetes. We demonstrate accurate segmentation of the vascular morphology for the superficial capillary plexus and deep vascular complex (SCP and DVC) using a convolutional neural network (CNN) for quantitative analysis. Methods: Retinal OCT-A with a 6x6mm field of view (FOV) were acquired using a Zeiss PlexElite. Multiple-volume acquisition and averaging enhanced the vessel network contrast used for training the CNN. We used transfer learning from a CNN trained on 76 images from smaller FOVs of the SCP acquired using different OCT systems. Quantitative analysis of perfusion was performed on the automated vessel segmentations in representative patients with DR. Results: The automated segmentations of the OCT-A images maintained the hierarchical branching and lobular morphologies of the SCP and DVC, respectively. The network segmented the SCP with an accuracy of 0.8599, and a Dice index of 0.8618. For the DVC, the accuracy was 0.7986, and the Dice index was 0.8139. The inter-rater comparisons for the SCP had an accuracy and Dice index of 0.8300 and 0.6700, respectively, and 0.6874 and 0.7416 for the DVC. Conclusions: Transfer learning reduces the amount of manually-annotated images required, while producing high quality automatic segmentations of the SCP and DVC. Using high quality training data preserves the characteristic appearance of the capillary networks in each layer. Translational Relevance: Accurate retinal microvasculature segmentation with the CNN results in improved perfusion analysis in diabetic retinopathy.

description: The Brownian web can be roughly described as a family of coalescing one-dimensional Brownian motions starting at all times in $\R$ and at all points of $\R$. It was introduced by Arratia; a variant was then studied by Toth and Werner; another variant was analyzed recently by Fontes, Isopi, Newman and Ravishankar. The two-dimensional \emph{Poisson tree} is a family of continuous time one-dimensional random walks with uniform jumps in a bounded interval. The walks start at the space-time points of a homogeneous Poisson process in $\R^2$ and are in fact constructed as a function of the point process. This tree was introduced by Ferrari, Landim and Thorisson. By verifying criteria derived by Fontes, Isopi, Newman and Ravishankar, we show that, when properly rescaled, and under the topology introduced by those authors, Poisson trees converge weakly to the Brownian web.

description: Im Wietmarscher Moor liegen auf Grund einer langjährigen, intensiven Abtorfung und Entwässerung der 160 ha großen Fläche ungünstige Voraussetzungen für eine ganzﬂächige Wiedervernässung vor. Auch in diesem Moor können aufgrund eines zunehmend hohen Hemerobiegrades bestimmte Leitbilder nicht mehr realisiert werden. Deswegen wurden für das Wietmarscher Moor zwei Konzepte mit unterschiedlichen Zielsetzungen entwickelt. Ein Maximalkonzept, das eine vollständige Hochmoorrevitalisierung in der gesamten Fläche anhand von bestehenden Handlungsempfehlungen (Geofakten 14) anstrebt und ein Realkonzept, bei dem eine Hochmoorrevitalisierung nur in dafür geeigneten Bereichen unter Berücksichtigung der noch vorhandenen Schwarztorfreste durchgeführt werden soll. Auf der restlichen Fläche sollen durch Pﬂegemaßnahmen sowie durch die Zulassung freier Sukzession alternative Niedermoor- bzw. Feuchtbiotope entstehen. Anhand einer Betrachtung der Realisierbarkeiten und der zu erwartenden Standortdiversitäten beider Konzepte wird die Umsetzung des Realkonzeptes empfohlen. Demnach wird es auf einer Fläche von 20 ha durch die Anlage von Poldern zur Hochmoorentwicklung und auf 17 ha durch den Verschluss von Gräben zur Röhricht- oder Bruchwaldbildung kommen. Die Standortdiversität wird sich beim Realkonzept im Vergleich zum aktuellen Zustand sowie zum Maximalkonzept deutlich erhöhen. Aufgrund der Betrachtung der Stratigraphie von nahe gelegenen, teils wiedervernässten Referenzﬂächen, kann für die geplanten Polder von guten Revitalisierungschancen ausgegangen werden.
description: The Wietmarscher Moor covers about 160 ha of a former industrially, cut-over raised bog. Due to a long-term and intensive peat-extraction as well as drainage of the area, starting conditions for rewetting are unfavourable. Because of this two concepts with different aims have been developed. The maximum concept adheres to existing guidelines (Geofakten l4) for rewetting peat-extracted areas focused on bog revitalization over the whole area. The real concept is based on the existing conditions in the area and aims at developing a raised bog in suitable areas as well as alternative habitats in the other sections of the Wietmarscher Moor. By comparing the feasibility and expected habitat diversity of both concepts, the implementation of the real concept is recommended. On an area of approx. 20 ha polders for precipitation retention will be created and about 17 ha will be rewetted by ditch closures. The number of different habitats will increase significantly compared to the current state and to the maximum concept. By considering the stratigraphy in nearby partly rewetted reference areas, good chances of revitalization can be assumed for the planned polders.

description: The nature of the fuel that drives today's cosmic acceleration is an open and tantalizing mystery. We entertain the suggestion that the acceleration is not the manifestation of yet another new ingredient in the cosmic gas tank, but rather a signal of our first real lack of understanding of gravitational physics. By requiring that the underlying gravity theory respects Birkhoff's law, we derive the modified gravitational force-law necessary to generate any given cosmology, without reference to the fundamental theory, revealing modifications of gravity at scales typically much smaller than today's horizon. We discuss how through these modifications, the growth of density perturbations, the late-time integrated Sachs--Wolfe effect, and even solar-system measurements may be sensitive to whether today's cosmic acceleration is generated by dark energy or modified gravitational dynamics, and are subject to imminent observational discrimination. We argue how these conclusions can be more generic, and probably not dependent on the validity of Birkhoff's law.

description: We study the CP-violating asymmetry in nonleptonic decay $Λ\to pπ$. By employing the Skyrme model to calculate this decay amplitude contributed by the gluonic diploe operator, we find a possible large CP-violating asymmetry could be expected, which is consistent with the previous study.

title: Mechanisms of activation of the leukocyte integrin LFA-1
Creators: name: McDowall, Alison Jane
Publisher: name: The Open University
Year: 2001

description: This work was undertaken to characterise the interaction of the leukocyterestricted integrin LFA-1 (CD1la/CD18) with its ligands. LFA-1 function is critical for an immune response and, for example, allows leukocyte binding and transmigration across the endothelium, antigen presentation and cytotoxic T lymphocyte-mediated killing. The ligands for LFA-1 are the Intercellular Adhesion Molecules (ICAMs), with ICAM-1, ICAM-2 and ICAM-3 being the best characterised.

The binding sites on ICAM-1 and ICAM-3 for LFA-1 were investigated with the use of antibodies and mutated proteins. The following regions were found to have a role in binding LFA-1: the CFG face of ICAM-3 domain 1; domain 2 of ICAM-1; a residue in domain 1 of ICAM-1 that is mutated at high frequency in African populations and is associated with susceptibility to cerebral malaria.

Binding of Mg2+ or Mn2+ to the extracellular region of LFA-1 and intracellular signalling can both stimulate LFA-1 to adhere to ICAM-1, but by different processes. The former mechanism induces a high affinity form of LFA-1, which was shown to be achieved by an inter-domain movement involving the I domain of the LFA-1 α subunit. This is the first physical evidence for a conformational change occurring in an integrin upon activation. The mechanism by which intracellular signalling activates LFA-1 was demonstrated to involve calpaindependent clustering of LFA-1 in the membrane, thus increasing the avidity of LFA-1 for ICAM-1.

Leukocyte Adhesion Deficiency-1 and Glanzmann's Thrombasthenia are genetic disorders in which mutations in the integrin genes result in absence of expression or expression of a non-functional integrin. The defects in function of leukocytes from a patient with clinical features of both disorders were studied. The results suggest that the patient has a novel form of integrin dysfunction in which integrins are expressed at normal levels, can be induced to bind their ligands by mechanisms which increase the affinity of interaction, but cannot be stimulated to bind ligand by intracellular signalling pathways.

description: Antiferromagnetic materials can host spin-waves with polarizations ranging from circular to linear depending on their magnetic anisotropies. Until now, only easy-axis anisotropy antiferromagnets with circularly polarized spin-waves were reported to carry spin-information over long distances of micrometers. In this article, we report long-distance spin-transport in the easy-plane canted antiferromagnetic phase of hematite and at room temperature, where the linearly polarized magnons are not intuitively expected to carry spin. We demonstrate that the spin-transport signal decreases continuously through the easy-axis to easy-plane Morin transition, and persists in the easy-plane phase through current induced pairs of linearly polarized magnons with dephasing lengths in the micrometer range. We explain the long transport distance as a result of the low magnetic damping, which we measure to be below 0.0001 as in the best ferromagnets. All of this together demonstrates that long-distance transport can be achieved across a range of anisotropies and temperatures, up to room temperature, highlighting the promising potential of this insulating antiferromagnet for magnon-based devices.

Comment on "Detection of small comets with a ground-based telescope" by Frank and Sigwarth

description: Frank and Sigwarth (2001,JGRSP,106,A3,3665; FS) report on an optical search for small comets in which they report detection of nine faint trails. FS claim that these trails are produced by low-mass, low-albedo ob-jects whose inferred number density is consistent with that predicted by the small comet hypothesis. The images used for the search were the same as those obtained in a previous unsuccessful optical search for small comets reported by Mutel and Fix (2000, JGRSP,105,24907; MF). The results of these two independent analyses of the same image dataset are not formally in disagreement, since all detections reported by FS are fainter than the minimum detectable magnitude limit (16.5) determined by MF. However, since the conclusions are quite different, we have independently re-analyzed the original search images for evidence of the faint detections reported by FS. In particular, we have carefully examined whether the three putative trails whose positions are available satisfy several necessary criteria for a candidate grouping of excess-count pixels to be caused by a celestial object. While we have not evaluated the formal statistical significance of faint detections, all three claimed detections fail one or more independent criteria required for a valid detection. In addition, both the level and shape of the claimed integral detection rate versus magnitude are in strong disagreement with the inte-gral number density of the small comets hypothesis. We conclude that unless the remaining claimed detections can prove otherwise, the lack of detections after "careful examination" of the 1,500 search images described in FS provides the most compelling evidence yet published against the small comet hypothesis.

description: Observations of damped Lyman alpha systems offer a unique window on the neutral-gas reservoirs that gave rise to galaxies at high redshifts. This review focuses on critical properties such as the H I and metal content of the gas and on independent evidence for star formation. Together, these provide an emerging picture of gravitationally bound objects in which accretion of gas from the IGM replenishes gas consumed by star formation. Other properties such as dust content, molecular content, ionized-gas content, gas kinematics, and galaxy identifications are also reviewed. These properties point to a multiphase ISM in which radiative and hydrodynamic feedback processes are present. Numerical simulations and other types of models used to describe damped Lyman alpha systems within the context of galaxy formation are also discussed.

description: Returns to ownership and returns to owner-supplied labor often are commingled in the net income form practice summary measure reported in surveys of professional service firms. This measurement problem poses difficulties in interpreting analyses of output and input market performance. The paper begins to addresses the problem by demonstrating a method for separating labor and entrepreneurial components of net income reported by physicians in a 1984 survey by the American Medical Association. A wage equation, adjusted for negative selection into employee practice arrangements and estimated on employee physician data, is used to predict the the opportunity wage rates for self-employed physicians. Overall, approximately 16 percent of the net income of self-employed physicians in general and family practice and in internal medicine is the result of entrepreneurship; the remaining 84 percent is attributable to labor.
Holography and $SL(2,\bR)$ symmetry in 2D Rindler spacetime

description: It is shown that it is possible to define quantum field theory of a massless scalar free field on the Killing horizon of a 2D-Rindler spacetime. Free quantum field theory on the horizon enjoys diffeomorphism invariance and turns out to be unitarily and algebraically equivalent to the analogous theory of a scalar field propagating inside Rindler spacetime, nomatter the value of the mass of the field in the bulk. More precisely, there exists a unitary transformation that realizes the bulk-boundary correspondence under an appropriate choice for Fock representation spaces. Secondly, the found correspondence is a subcase of an analogous algebraic correspondence described by injective *-homomorphisms of the abstract algebras of observables generated by abstract quantum free-field operators. These field operators are smeared with suitable test functions in the bulk and exact 1-forms on the horizon. In this sense the correspondence is independent from the chosen vacua. It is proven that, under that correspondence the ``hidden'' $SL(2,\bR)$ quantum symmetry found in a previous work gets a clear geometric meaning, it being associated with a group of diffeomorphisms of the horizon itself.

Working memory and reading comprehension in Arabic language
Creators: name: El-Mir, Mohammed
Publisher: name: figshare
Year: 2020
Subjects: Applied Psychology

description: The present study examined the relationships between Working memory (WM) and reading comprehension in native Arabic 3rd graders. WM is responsible for storing and processing incoming information (Baddeley & Hitch, 1974). The comprehender gradually constructs a mental model of the text (Kintsch & van Dijk, 1983). Thus, WM contributes to reading comprehension; because it helps to store medial products during the processing of the printed information. Previous studies have found correlations between WM and reading comprehension in other languages like English (Daneman & Carpenter, 1980; Just & Carpenter, 1992); however we have no reliable data about the effect of WM on reading comprehension in Arabic language. So, in this study, WM capacity is expected to explain performance in reading comprehension in Arabic, consequently high WM span readers perform better than low WM span readers in reading comprehension tasks.

description: High contrast imaging is the primary path to the direct detection and characterization of Earth-like planets around solar-type stars; a cleverly designed internal coronagraph suppresses the light from the star, revealing the elusive circumstellar companions. However, future large-aperture telescopes ($>$4~m in diameter) will likely have segmented primary mirrors, which causes additional diffraction of unwanted stellar light. Here we present the first high contrast laboratory demonstration of an apodized vortex coronagraph (AVC), in which an apodizer is placed upstream of a vortex focal plane mask to improve its performance with a segmented aperture. The gray-scale apodization is numerically optimized to yield a better sensitivity to faint companions assuming an aperture shape similar to the LUVOIR-B concept. Using wavefront sensing and control over a one-sided dark hole, we achieve a raw contrast of $2\times10^{-8}$ in monochromatic light at 775~nm, and a raw contrast of $4\times10^{-8}$ in a 10\% bandwidth. These results open the path to a new family of coronagraph designs, optimally suited for next-generation segmented space telescopes.

description: Promises by retailers to match the prices of their competitors give an impression of fierce price competition. On the other hand, these policies may deter rivals from cutting prices because the threat of price-matching makes it more likely that market share will not be gained. This paper empirically tests these two conflicting theories using data collected from grocery stores. in a market where several stores had announced that they would match the prices of the low-price supermarket. The evidence supports the theory that pricematching policies help supermarkets avoid price competition and therefore lead to generally higher prices.
