description: The article presents the diversification of agriculture efficiency of Chinese provinces in 2013 based on the Data Envelopment Analysis method. The model features the following variables: 1 effect (value of purchased agricultural products) and 5 inputs (area of agricultural land, number of people employed in agriculture, use of fertilizers, number of tractors, livestock). This article presents the use of input-oriented CCR and BCC model, to determine overall technical efficiency, pure technical efficiency and scale efficiency of agriculture in Chinese provinces. The analysis gives the possibility of creating a ranking of provinces. The highest agriculture efficiency during the period was achieved by 7 provinces (in CCR model) and 16 provinces (in BCC model). The results point out reasons for inefficiency and provide directions of improvement for inefficient Decision Making Units.

description: The implementation of a policy of sustainable development requires taking action being aimed at a management of area which his development will guarantee with the possibility of using resources of the natural environment. An evaluation of the state and directions of the development of the non-agricultural business activity is a purpose of this study in rural and urban – rural areas of two districts: Augustów and Hajnówka. The study was conducted based on the analysis of secondary materials from the Central Statistical Office and the Podlasie Agricultural Advisory Centre in Szepietowo, took time range 2011-2014. The results have shown that the district augustowski and hajnowski were dominated areas legally protected by law, including Natura 2000, which is perceived as the barrier of the entrepreneurship development, factor limiting investments and the growth in the economy. Despite this, low figure of service business entities, connected with accommodating and maintaining is worrying. Deficiency in this segment farmhouses may try to fill up.

description: The aim of the study was to analyze factors affecting adult education among the rural population. The study used data from 2013, based on the 7688 questionnaires. Logistic regression model was used to determine the education activity. Research shows that the education activity depends mostly on responder’s status on the labor market (working individuals more frequently continue education), their competences and regular use of the Internet, age and professional experience. In terms of levels of education, people with primary education are least likely to continue learning. Possession of the individual farm has a negative effect on the rural population’s educational activity.
Unveiling the Inner Disk Structure of T Tauri Stars

description: We present near-infrared spectra of the excess continuum emission from the innermost regions of classical T Tauri disks. In almost all cases, the shape of the excess is consistent with that of a single-temperature blackbody with T ~ 1400 K, similar to the expected dust sublimation temperature for typical dust compositions. The amount of excess flux roughly correlates with the accretion luminosity in objects with similar stellar properties. We compare our observations with the predictions of simple disk models having an inner rim located at the dust sublimation radius, including irradiation heating of the dust from both the stellar and accretion luminosities. The models yield inner rim radii in the range 0.07-0.54 AU, increasing with higher stellar and accretion luminosities. Using typical parameters which fit our observed sample, we predict a rim radius ~ 0.2 AU for the T Tauri star DG Tau, which agrees with recent Keck near-infrared interferometric measurements. For large mass accretion rates, the inner rim lies beyond the corotation radius at (or within) which magnetospheric accretion flows are launched, which implies that pure gaseous disks must extend inside the dust rim. Thus, for a significant fraction of young stars, dust cannot exist in the innermost disk, calling into question theories in which solid particles are ejected by a wind originating at the magnetospheric radius.

description: For practical reasons, many forecasts of case, hospitalization and death counts in the context of the current COVID-19 pandemic are issued in the form of central predictive intervals at various levels. This is also the case for the forecasts collected in the COVID-19 Forecast Hub (https://covid19forecasthub.org/). Forecast evaluation metrics like the logarithmic score, which has been applied in several infectious disease forecasting challenges, are then not available as they require full predictive distributions. This article provides an overview of how established methods for the evaluation of quantile and interval forecasts can be applied to epidemic forecasts in this format. Specifically, we discuss the computation and interpretation of the weighted interval score, which is a proper score that approximates the continuous ranked probability score. It can be interpreted as a generalization of the absolute error to probabilistic forecasts and allows for a decomposition into a measure of sharpness and penalties for over- and underprediction.
Disc orientations in pre-main-sequence multiple systems. A study in southern star formation regions

description: Classical T Tauri stars are encircled by accretion discs most of the time unresolved by conventional imaging observation. However, numerical simulations show that unresolved aperture linear polarimetry can be used to extract information about the geometry of the immediate circumstellar medium that scatter the starlight. Monin, Menard & Duchene (1998) previously suggested that polarimetry can be used to trace the relative orientation of discs in young binary systems in order to shed light on the stellar and planet formation process. In this paper, we report on new VLT/FORS1 optical linear polarisation measurements of 23 southern binaries spanning a range of separation from 0.8'' to 10''. In each field, the polarisation of the central binary is extracted, as well as the polarisation of nearby stars in order to estimate the local interstellar polarisation. We find that, in general, the linear polarisation vectors of individual components in binary systems tend to be parallel to each other. The amplitude of their polarisations are also correlated. These findings are in agreement with our previous work and extend the trend to smaller separations. They are also similar to other studies, e.g., Donar et al. 1999; Jensen et al. 2000, 2004; Wolf et al. 2001. However, we also find a few systems showing large differences in polarisation level, possibly indicating different inclinations to the line-of-sight for their discs.

description: The aim of the paper is to present the problems associated with the correct calculation of the economic impact of the operation of VAT in agriculture. This applies to flat-rate farmers and farmers who resigned from the lump sum and became active VAT payers. There were analyzed selected publications from the years 2000-2015, addressing the problem of VAT in agriculture and websites containing „calculators” to support the calculation effects of the withdrawal of farmers from the lump sum. It turned out that in spite of the long existence of VAT in agriculture the principles of operation are misinterpreted and wrongly presented the economic impact of the resignation of the status of the flat-rate farmer.

description: The purpose of this paper was to present various forms of implementation of the concepts of the bio-economy in organic farms. That assumption was followed by the critical analysis of the domestic and foreign literature related to usage of the biotechnological solutions and improvement in organic farms. It also allowed to create the survey that was sent to farmers from Mecklenburg and West Pomerania. The analysis showed that organic farms slowly implement biotechnological ideas (the slow implementation is related to its high costs and small income). The analysis also showed that farmers from Mecklenburg use modern technologies more often.

description: In article there is presented the concept of sustainable developement for agriculture. It is mentioned that problem of sustainability may be considered in the context of inequalities in distribution of agricultural income against the differentation in variables such as total ouput, subsidies or total utilised agricultural area. The conducted analysis show that there are significant differences between levels of income inequality in the countries surveyed, and that there is no direct evidence for the intensification of production. Income inequality are in fact usually smaller than in the case of the production The highest level of sustainability and development has been noted in countries with relatively equal distribution of income among farms.

description: In this paper, we mainly analyze the long-time asymptotics of high-order soliton for the Hirota equation. Two different Riemann-Hilbert representations of Darboux matrix with high-order soliton are given to establish the relationships between inverse scattering method and Darboux transformation. The asymptotic analysis with single spectral parameter is derived through the formulas of determinant directly. Furthermore, the long-time asymptotics with $k$ spectral parameters is given by combining the iterated Darboux matrix and the result of high-order soliton with single spectral parameter, which discloses the structure of high-order soliton clearly and is possible to be utilized in the optic experiments.

Ether theory of gravitation: why and how?

Year: 2004
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: Gravitation might make a preferred frame appear, and with it a clear space/time separation--the latter being, a priori, needed by quantum mechanics (QM) in curved space-time. Several models of gravitation with an ether are discussed: they assume metrical effects in an heterogeneous ether and/or a Lorentz-symmetry breaking. One scalar model, starting from a semi-heuristic view of gravity as a pressure force, is detailed. It has been developed to a complete theory including continuum dynamics, cosmology, and links with electromagnetism and QM. To test the theory, an asymptotic scheme of post-Newtonian approximation has been built. That version of the theory which is discussed here predicts an internal-structure effect, even at the point-particle limit. The same might happen also in general relativity (GR) in some gauges, if one would use a similar scheme. Adjusting the equations of planetary motion on an ephemeris leaves a residual difference with it; one should adjust the equations using primary observations. The same effects on light rays are predicted as with GR, and a similar energy loss applies to binary pulsars.

description: A Fast Exhaust Nephelometer (FEN) is developed for light scattering measurement of particles produced by unsteady combustion processes, such as in diesel engines. The FEN simultaneously measures the light scattering intensity at three angles to infer the mass concentration (Cm), the geometric mass mean mobility diameter (dm,g), and the geometric standard deviation (σm,g) of polydisperse soot. A kernel is used to determine Cm, dm,g, and σm,g based on lookup tables generated with the Rayleigh-Debye-Gans light scattering model for fractal aggregates (RDGFA); the model incorporates the variation of the primary particle size (dp) with aggregate size (da), and nine parameters related to the soot properties, and one to the FEN optics. These parameters are determined a priori from literature and Transmission Electron Microscopy (TEM). The inverted Cm and dm,g are within ±10% of the gravimetric mass concentration and SMPS mobility diameter. This, however, largely depends on the choice of the parameters used to generate the lookup tables. A parametric study shows the inferred mass is most sensitive to uncertainties in the soot refractive index, the primary particle size, and the fractal pre-factor kf. Considering the wide range of soot refractive indices in the literature and the sensitivity of the morphological parameters to the processing of soot images, the uncertainty in mass concentration would be over 40%. Because of this, a novel approach of relating the size of primary particles to the size of aggregates is incorporated for the first time in the light scattering model, and reduces the uncertainty to ±25-30%.

Using this map we establish a connection between the deformed Kowalevski top on $e(3)$ proposed by Sokolov and the Kowalevski top on $so(4)$. The connection between these systems leads to the separation of variables for the deformed system on $e(3)$ and yields the natural $5\times 5$ Lax pair for the Kowalevski top on $so(4)$.

Regulation of macrophage apoptosis via Bcl-2 family members and ceramide
Creators: name: Wang, Shih Wei
Publisher: name: University of British Columbia
Year: 2011

description: Apoptosis is an important mechanism involved in regulating the number of macrophages present at sites of inflammation. Several lines of evidence indicate that blocking macrophage apoptosis can increase atherosclerosis. We previously reported that oxidized LDL (oxLDL) can inhibit apoptosis in cultured bone marrow-derived macrophages in part by activating the phosphoinositide 3 kinase (PI3K)/protein kinase B (PKB) pathway and subsequent expression of pro-survival protein Bcl-X L. Here we report that oxLDL also alters the levels of the pro-apoptotic protein, Bax. This effect of oxLDL on Bax regulation was at a post-transcriptional level, mediated by accelerated degradation via the ubiquitin-proteasome pathway. However, Bax knockout macrophages were not resistant to apoptosis following cytokine withdrawal, suggesting that the downregulation of Bax is only partially responsible for the pro-survival effects mediated by oxLDL in these cells. OxLDL is also able to increase the expression of the prosurvival relative, Mcl-1. The effect of oxLDL on Bax degradation and Mcl-1 expression was blocked by inhibitors of the PI3K/PKB pathway. To investigate the upstream receptor(s) activated by oxLDL to mediate macrophage survival, we used pertussis toxin (PTX) to test whether Gi protein coupled receptors are involved. Unexpectedly, we found that PTX by itself selectively blocks macrophage apoptosis in a dose-dependent manner. PTX acts in part by inhibiting acid sphingomyelinase activity which in turn prevents generation of ceramide during apoptosis. A Gi activator peptide, mastoparan, increased ceramide levels in macrophage and induced apoptosis, but pre-treatment with PTX partially overrode mastoparan-induced apoptosis. PTX failed to prevent ASMase activation or apoptosis in macrophages lacking toll-like receptor 4 (TLR4). Like oxLDL, the anti-apoptotic effect of PTX also activated the PI3K/PKB pathway which led to nuclear localization of the transcription factor NFκB and up-regulation of Bcl-X L. These results indicate that Gi proteins, TLR4, ASMase and the PI3K/PKB pathway are crucial components for regulation of macrophage apoptosis. We also looked at regulation of ceramide generation in response to apoptosis. Using ASMase-/- mice, we found that ceramide is still generated. Using inhibitors to enzymes involved in the de novo ceramide synthesis pathway, we concluded that both de novo synthesis and sphingomyelin hydrolysis can contribute to ceramide generation during macrophage apoptosis.

description: The competition between spin glass (SG), antiferromagnetism (AF) and Kondo effect is studied here in a model which consists of two Kondo sublattices with a gaussian random interaction between spins in differents sublattices with an antiferromagnetic mean Jo and standard deviation J. In the present approach there is no hopping of the conduction electrons between the sublattices and only spins in different sublattices can interact. The problem is formulated in the path integral formalism where the spin operators are expressed as bilinear combinations of Grassmann fields which can be solved at mean field level within the static approximation and the replica symmetry ansatz. The obtained phase diagram shows the sequence of phases SG, AF and Kondo state for increasing Kondo coupling. This sequence agrees qualitatively with experimental data of the Ce_{2} Au_{1-x} Co_{x} Si_{3} compound.

description: We present an analysis on the uptake of open access on COVID-819 related literature as well as the social media attention they gather when9compared with non OA papers. We use a dataset of publications curated by10Dimensions and analyze articles and preprints. Our sample includes 11,68611publications of which 67.5% are openly accessible. OA publications tend to receive the largest share of social media attention as measured by the Altmetric13Attention Score. 37.6% of OA publications are bronze, which means toll journals are providing free access. MedRxiv contributes to 36.3% of documents inrepositories but papers in BiorXiv exhibit on average higher AAS. We predict the growth of COVID-19 literature in the following 30 days estimating ARIMA models for the overall publications set, OA vs. non OA and by location of the document (repository vs. journal). We estimate that COVID-19 publications will double in the next 20 days, but non OA publications will grow at a higher rate than OA publications. We conclude by discussing the implications of such findings on the dissemination and communication of research findings to mitigate the coronavirus outbreakPreview

description: The large model size, high computational operations, and vulnerability against membership inference attack (MIA) have impeded deep learning or deep neural networks (DNNs) popularity, especially on mobile devices. To address the challenge, we envision that the weight pruning technique will help DNNs against MIA while reducing model storage and computational operation. In this work, we propose a pruning algorithm, and we show that the proposed algorithm can find a subnetwork that can prevent privacy leakage from MIA and achieves competitive accuracy with the original DNNs. We also verify our theoretical insights with experiments. Our experimental results illustrate that the attack accuracy using model compression is up to 13.6% and 10% lower than that of the baseline and Min-Max game, accordingly.

Hepatitis C and G virus infection and non-Hodgkin lymphoma in a case-control study from British Columbia, Canada
Creators: name: Lai, Agnes Suet Wah
Publisher: name: University of British Columbia
Year: 2011

description: Background & Aims: Both Hepatitis C virus (HCV) and Hepatitis G virus (HGV) are single-stranded positive sense RNA viruses belonging to the Flaviviridae family. Epidemiological evidence has suggested an association between HCV infection and non Hodgkin lymphoma (NHL), but the association has mostly been seen in regions where the prevalence is high. Canadian studies have reported no significant association. The role of HGV infection in NHL has also been suggested, but there is little epidemiologic evidence. We investigated HCV, HGV and risk of NHL in a population-based case-control study in British Columbia, Canada. Methods: Cases were aged 20-79, diagnosed between March 2000 and February 2004, and residents in Greater Vancouver or Victoria. Cases with HIV or a prior transplant were excluded. Controls were chosen from the Provincial Health Insurance Client Registry and were age/sex/region frequency matched to cases. Results: Antibodies for HCV were measured in plasma of 795 cases and 697 control subjects. HCV seropositivity was 2.4% in cases and 0.7% in controls [odds ratio (OR)=3.4, (95%) confidence interval (CI)=1.3-9.1)]. The highest risks were associated with diffuse large B-cell lymphoma (OR=8.3, 95%CI=2.9-23.9), marginal zone lymphoma (OR=4.5, 95%CI=1.1-19.2) and small lymphocytic lymphoma/chronic lymphocytic leukemia (OR=6.9, 95%CI=1.3-36.8). HGV viremia was determined in plasma by the RT-PCR technique in 553 cases and 438 control subjects. The prevalence of HGV viremia was 4.5% in cases and 1.8% in controls (OR=3.2, 95%CI=1.4-7.3). The associations were strongest for cases with diffuse large B-cell lymphoma (OR=5.7, 95%CI=2.3-14.6), marginal zone lymphoma (OR=3.5, 95%CI=1.2-10.4) and other/unknown B-cell lymphoma (OR=4.9, 95%CI=1.3-17.6). Interpretation: Our results provide further evidence that exposure to HCV and HGV contribute to NHL risk. The associations were strongest for cases with diffuse large B-cell lymphoma and marginal zone lymphoma.

Peak effect at the weak- to strong pinning crossover

description: In type-II superconductors, the magnetic field enters in the form of vortices; their flow under application of a current introduces dissipation and thus destroys the defining property of a superconductor. Vortices get immobilized by pinning through material defects, thus resurrecting the supercurrent. In weak collective pinning, defects compete and only fluctuations in the defect density produce pinning. On the contrary, strong pins deform the lattice and induce metastabilities. Here, we focus on the crossover from weak- to strong bulk pinning, which is triggered either by increasing the strength $f_\mathrm{p}$ of the defect potential or by decreasing the effective elasticity of the lattice (which is parametrized by the Labusch force $f_\mathrm{Lab}$). With an appropriate Landau expansion of the free energy we obtain a peak effect with a sharp rise in the critical current density $j_\mathrm{c} \sim j_0 (a_0ξ^2 n_p) (ξ^2/a_0^2) (f_\mathrm{p}/f_\mathrm{Lab} -1)^2$.

description: The Jotun Field was discovered in 1994 and production started in October 1999. The field consists of three structures located on the western flank of the Utsira High, close to the eastern pinch-out of the Tertiary submarine fan system. The field currently has 16 horizontal producers and one water injector. The reservoir at Jotun is comprised of Palaeocene Heimdal Formation sands shed from the East Shetland Platform and transported across the Viking Graben area onto the Utsira High by high density gravity flow processes dominated by sandy turbidites. These distal gravity flow deposits display both thin-bedded sands alternating with shales and thicker, more massive sandstones (tens of meters thick). Minor sand injections occur throughout the field but are volumetrically insignificant. The production wells in one of the structures are completed in a slump and injection complex above thick massive reservoir sands. Seven generic facies described from core is applied to characterise the Jotun Field reservoir: Facies 1: High Density Turbidite; Facies 2: Low Density Turbidite; Facies 3: Sandy Debrite; Facies 4: Muddy Debrite; Facies 5: Turbiditic Shale; Facies 6: Hemipelagic Shale; Facies 7: Injectite.

description: In this paper, we study affine manifolds endowed with linear foliations. These are foliations defined by vector subspaces invariant by the linear holonomy. We show that an $n$-dimensional compact, complete, and oriented affine manifold endowed with a codimension $1$ linear foliation ${\cal F}$ is homeomophic to the $n$-dimensional torus if the leaves of ${\cal F}$ are simply connected. Let $(M,\nabla_M)$ be a $3$-dimensional compact affine manifold endowed with a codimension $1$ linear foliation. We prove that $(M,\nabla_M)$ has a finite cover which is homeomorphic to the total space of a bundle over the circle if its developing map is injective, and has a convex image.
Insights into the shockwave attenuation in miniature shock tubes

description: Miniature shock tubes are finding growing importance in a variety of interdisciplinary applications. There is a lack of experimental data to validate the existing shock tube flow models that explain the shockwave attenuation in pressure-driven miniature shock tubes. This paper gives insights into the shock formation and shock propagation phenomena in miniature shock tubes of 2mm, 6mm, and 10mm square cross-sections operated at diaphragm rupture pressure ratios in the range 5-25 and driven section initially at ambient conditions. Pressure measurements and visualization studies are carried out in a new miniature table-top shock tube system using nitrogen and helium as driver gases. The experimental findings are validated using a shock tube model explained in terms of two regions; (1) The shock formation region, dominated by wave interactions due to the diaphragm's finite rupture time. (2) The shock propagation region, where the shockwave attenuation occurs mainly due to wall effects and boundary layer growth. Correlations to predict the variation of shock Mach number in the shock formation region and shock propagation region work well for the present findings and experimental data reported in the literature. Similar flow features are observed in the shock tubes at the same dimensionless time stamps. The formation of the planar shock front scales proportionally with the diameter of the shock tube. The peak Mach number attained by the shockwave is higher as the shock tube diameter increases.
Could the variation in quasar luminosity, due to extra dimension 3-brane in RS model, be measurable?

description: We propose an alternative theoretical approach showing how the existence of an extra dimension in RS model can estimate the correction in the Schwarzschild radius of black holes, and consequently its measurability in terms of the variation of quasar luminosity, which can be caused by a imprint of an extra dimension endowing the geometry of a brane-world scenario in an AdS_5 bulk. This paper is intended to investigate the variation of luminosity due to accretion of gas in black holes (BHs) in the center of quasars, besides also investigating the variation of luminosity in supermassive BHs by brane-world effects, using RS model.

description: For a manifold $M$ with an integral closed 3-form $ω$, we construct a $PU(H)$-bundle and a Lie groupoid over its total space, together with a curving in the sense of gerbes. If the form is non-degenerate, we furthermore give a natural Lie 2-algebra quasi-isomorphism from the observables of $(M,ω)$ to the weak symmetries of the above geometric structure, generalising the prequantisation map of Kostant and Souriau.

Reachability problems for products of matrices in semirings

description: We consider the following matrix reachability problem: given $r$ square matrices with entries in a semiring, is there a product of these matrices which attains a prescribed matrix? We define similarly the vector (resp. scalar) reachability problem, by requiring that the matrix product, acting by right multiplication on a prescribed row vector, gives another prescribed row vector (resp. when multiplied at left and right by prescribed row and column vectors, gives a prescribed scalar). We show that over any semiring, scalar reachability reduces to vector reachability which is equivalent to matrix reachability, and that for any of these problems, the specialization to any $r\geq 2$ is equivalent to the specialization to $r=2$. As an application of this result and of a theorem of Krob, we show that when $r=2$, the vector and matrix reachability problems are undecidable over the max-plus semiring $(Z\cup\{-\infty\},\max,+)$. We also show that the matrix, vector, and scalar reachability problems are decidable over semirings whose elements are ``positive'', like the tropical semiring $(N\cup\{+\infty\},\min,+)$.

description: This report provides an overview of the water resources for the TintinaraCoonalpyn PWA (TCPWA) and includes: A general assessment of the groundwater resources for each of the aquifers in the PWA. A description (for both the unconfined and confined aquifers) of: The management approach adopted for the sustainable use of the resource (generally referred to as permissible annual volume) and a description of the manner in which the sustainable limits of use can be determined. Where separate management areas exist within the PWA, the adopted limits of sustainable groundwater use need to be tabulated. The assessment should identify any data deficiencies and requirements for future investigations. The historic and current demand (in terms of use) in each of the management areas within the PWA. The likely future demand for groundwater from this resource in the PWA. An assessment of whether the taking or use from the aquifers will have a detrimental effect on the quantity or quality of water that is available from any other water resource, both within and outside of the PWA; including a description of the likely nature and extent of any detrimental effects. An assessment of the current condition of the groundwater resources of both aquifers, taking into consideration available groundwater monitoring data to determine the capacity of both aquifers to meet the demands identified, on a continuing basis. This is to include recommendations for management intervention.
