description: According to the relevant data of farmers’ net income from the Hebei Statistical Yearbook 2009, seven indicators are selected covering regional gross production , the total output of the primary industry , the number of the people employed and the number of the large livestock at the end of year and so on, to analyze the factors that affect the per capita net income of farmers. The results show that the regional gross production is in positive proportion to the total output value of the primary industry and the influneces are great; the total output value of the non-agricultural industry and the local financial expenditure are the important factors that affect the income of farmers; though the total value of rural residents’ fixed investment is in positive proportion to the income of farmers, the degree is not so great; the regression coefficient of the number of people employed and the number of the large livestock at the end of year is negative and the number of people employed is a positive correlation to the net income of farmers. Based on the above analysis, the countermeasures on improving the income of rural residents are put forward: firstly, optimizing the rural indutrial structure, promoting the developement of the primary industry and improving the regional total output of production; secondly, Expanding the development channel of non-agricutlural economic and attracking the rural surplus laborers; thirdly, enlarging the local financial expenses and Expanding the developmental space of the three agricultural issues concerning peasants, countryside and agriculture.

description: We have calculated the equivalent widths of the absorption lines produced by Fe XXV and Fe XXVI in a Compton-thin, low-velocity photoionised material illuminated by the nuclear continuum in AGN. The results, plotted against the ionisation parameter and the column density of the gas, are a complement to those presented by Bianchi & Matt 2002 for the emission lines from the same ionic species. As an extension to the work by Bianchi & Matt 2002, we also present a qualitative discussion on the different contributions to the He-like iron emission line complex in the regimes where recombination or resonant scattering dominates, providing a useful diagnostic tool to measure the column density of the gas. Future high resolution missions (e.g., Astro-E2) will allow us to fully take advantage of these plasma diagnostics. In the meantime, we compare our results with an up-to-date list of Compton-thick and unobscured (at least at the iron line energy) Seyfert galaxies with emission and/or absorption lines from H- and He-like iron observed with Chandra and XMM-Newton.

description: Many recent studies have shown that deep neural models are vulnerable to adversarial samples: images with imperceptible perturbations, for example, can fool image classifiers. In this paper, we present the first type-specific approach to generating adversarial examples for object detection, which entails detecting bounding boxes around multiple objects present in the image and classifying them at the same time, making it a harder task than against image classification. We specifically aim to attack the widely used Faster R-CNN by changing the predicted label for a particular object in an image: where prior work has targeted one specific object (a stop sign), we generalise to arbitrary objects, with the key challenge being the need to change the labels of all bounding boxes for all instances of that object type. To do so, we propose a novel method, named Pick-Object-Attack. Pick-Object-Attack successfully adds perturbations only to bounding boxes for the targeted object, preserving the labels of other detected objects in the image. In terms of perceptibility, the perturbations induced by the method are very small. Furthermore, for the first time, we examine the effect of adversarial attacks on object detection in terms of a downstream task, image captioning; we show that where a method that can modify all object types leads to very obvious changes in captions, the changes from our constrained attack are much less apparent.

description: Based on the judicial explanation of the contractual management right of land, the thesis elaborates the definition of main body of contractual management right of rural land; right of possession, use right, usufruct of contractual management right of land; autonomy of production and operation; disposition of the products; expropriation and occupation compensation authority of contractual land respectively, in order to demonstrate the connotation of land contractual management. The thesis also analyzes perspicaciously the phenomenon of non-agricultural-use land and proclaiming phenomenon of contractual management right of land. We should establish normalized rural land property rights register system to perfect contractual management right of land. Proclaiming of agriculture land right also should adopt registration effectiveness so as to guarantee the legality of transference of agricultural land to non-agricultural land in terms of system. We should perfect rural land circulation in terms of normalizing land circulation laws and normalizing contractual farmers fees: in terms of the movable agricultural land right, we should further perfect the types and content of circulation and lessen non-legal form restrictions of circulation; in terms of contractual fees, we should normalize contractual fees of land in order to preclude the contradiction between the contractees and contractors arising from blank space of laws

description: The fabrication of single-carrier organic diodes from a series of sixteen molecular materials is reported. We experimentally demonstrate how the molecular structure affects the film morphology, and how the film morphology influences the diode performance. The compounds, with moderate molecular size and dendritic structures, are shown to be more favorable for good device performance than those small molecules with symmetry structures. The device turn-on voltage is found to be strongly dependent on the molecular first oxidation potentials. Independent of different anode materials, no obvious interfacial charge/dipole effects are observed in the devices. Our results may suggest that singlecarrier organic diode might offer a simple way for screeing appropriate molecular materials preferable for practical multilayer devices.

Detection and evaluation of decay in pulp and paper fibre supplies
Creators: name: Stirling, Roderick Anthony
Publisher: name: University of British Columbia
Year: 2009

description: Decay of wood chips is a significant economic threat to the pulp and paper industry. It results in reduced wood chip quality, which in turn causes decreased pulp yields and poorer pulp properties. The currently accepted methods to measure decay content in wood, such as buffering capacity and 1% caustic solubility, are too laborious to be of practical use in mill environments. The present research developed and investigated methods for rapidly quantifying decay in wood chips. Partial Least Squares (PLS) models were developed, based on FTIR and NIR spectra, to predict the extent of decay in wood chips, using caustic solubility, buffering capacity and basic wood density as indicators of decay. Data from these models were found to be highly correlated with existing methods (r2 > 0.80). In order to provide further validation for the PLS models, changes in wood chemistry underlying the decay were also examined. Extent of decay, as shown by the PLS models, was found to correlate with changes in the concentration of acetyl groups and lignin in the wood samples. Following the development and validation of the PLS models, the impacts of inoculum size and storage time on chip and thermo-mechanical pulp properties were determined. Results showed that both sound chips and chips incubated with varying quantities of a brown rot decay fungus for up to four months showed little decay and few changes in thermo-mechanical pulp properties. The most significant change was a drop in pulp brightness that was accounted for by the storage time, rather than fungal inoculation, of the wood chips. In order to understand the effects of pulping samples with high levels of brown-rot decay, softwood chips were heavily decayed by a brown rot fungus under ideal growth conditions in the laboratory. Both kraft and refiner mechanical pulps produced from these heavily decayed chips showed significant differences from pulps produced from equivalent sound chips. Mechanical pulps were prepared to a given freeness with less energy, but had significantly poorer strength and optical properties. Kraft pulps were produced in lower yields and consumed more alkali. The length of kraft fibres decreased with increasing decay and resulted in poorer strength properties. Existing research has shown that kraft pulping of chips heavily decayed by brown rot fungi is not economical (Hunt, 1978b). These results confirm this existing research and extend it to mechanical pulping, showing that heavily decayed chips exhibit similar detrimental effects on both kraft and mechanical pulping. The PLS models developed to estimate extent of decay were able to identify wood chips with poor pulping properties.

This work is aimed at a model-independent extraction of the $Δ^+$ magnetic moment from new precise measurements of this reaction. It also predicts the chiral behavior of $Δ$'s magnetic moment, which can be used to extrapolate the recent lattice QCD results to the physical point.

description: Connotation of land competitiveness is expatiated from both the narrow sense and broad sense. Evaluation index system of land competitiveness is established according to the 2008 China Statistical Yearbook and 2008 China Land Resources Statistical Yearbook. Efficiency Coefficient Method and Principal Component Analysis Method are used to evaluate the land competitiveness of 31 provincial units in China. Result shows that in the year 2007, land competitiveness gradually decreases from southeast to northwest. The land competitiveness and GDP per unit land have significant negative correlation. The rank of approved new construction land has low positive correlation with the rank of land competitiveness in China. This indicates that there is little correlation between the allocation of regional new construction land and the land use efficiency. Therefore, it is suggested that regional allocation of new construction land should be treated differently based on the evaluation result of land competitiveness.

description: This paper provides an account of the continuing challenges that the Goolarabooloo Community of Western Australia face, substantiating claims of genocide through the actions of the Nyamba Buru Yawuru (NBY) who are complicit in their illegal dealings with the Kimberley Land Council (KLC) and the Broome Shire Council (BSC). It is well documented that there are four (4) clans in the greater Broome region of Western Australia - Djukun, Walman, Julbayi and Leregon with the main camp of the Julbayi clan grounded at Yalanpanan, a big hill, near Edgar Station, Western Australia. Despite this knowledge the Julbayi clan are ignoring and overriding the decisions of other clans who make up the greater Yawuru community, which erodes cultural First Law. Through extinguishment of clan identity as detailed in prior written works of the Author, the Goolarabooloo are being dispossessed of Country which contravenes the United Nations Declaration on the Rights of Indigenous Peoples (UN General Assembly 2007).

description: The impurity Green function and dynamical susceptibilties for the two-channel Anderson impurity model are calculated. An exact expression for the self-energy of the impurity Green function is derived. The imaginary part of the self-energy scales as $\sqrt{|\w/T_K|}$ for $T\to 0$ serving as a hallmark for non-Fermi behavior. The many-body resonance is pinned to a universal value $1/(2πΔ)$ at $\w=0$. Its shape becomes increasingly more symmetric for the Kondo-regimes of the model. The dynamical susceptibilities are governed by two energy scales $T_K$ and $T_h$ and approach a constant value for $\w\to 0$, whereas relation $χ''(\w)\propto \w$ holds for the single channel model.

description: We study SU(N) plane-wave matrix theory up to fourth perturbative order in its large N planar limit. The effective Hamiltonian in the closed su(2) subsector of the model is explicitly computed through a specially tailored computer program to perform large scale distributed symbolic algebra and generation of planar graphs. The number of graphs here was in the deep billions. The outcome of our computation establishes the four-loop integrability of the planar plane-wave matrix model. To elucidate the integrable structure we apply the recent technology of the perturbative asymptotic Bethe Ansatz to our model. The resulting S-matrix turns out to be structurally similar but nevertheless distinct to the so far considered long-range spin-chain S-matrices of Inozemtsev, Beisert-Dippel-Staudacher and Arutyunov-Frolov-Staudacher in the AdS/CFT context. In particular our result displays a breakdown of BMN scaling at the four-loop order. That is, while there exists an appropriate identification of the matrix theory mass parameter with the coupling constant of the N=4 superconformal Yang-Mills theory which yields an eigth order lattice derivative for well seperated impurities (naively implying BMN scaling) the detailed impurity contact interactions ruin this scaling property at the four-loop order. Moreover we study the issue of ``wrapping'' interactions, which show up for the first time at this loop-order through a Konishi descendant length four operator.

description: Teachers should carefully balance the content of knowledge or knowledge that they wish to convey and then integrate with other skills, in particular, higher-level thinking skills (HOTS) into the effective learning and facilitation (LAF) process. This study will focus on the relevance of the application of the Marzano Dimensions of Learning Model (1993) as a guide in the argumentative essay writing process. The design of qualitative research using a case study approach has been used in this study. Two teachers who teach the Malay Language in Form Four in secondary school have been selected as participants in the study using a purposeful sampling technique. The data collection process for both study participants was performed through in-depth interviews, classroom observations, and student argumentative essay analysis. While the data is analyzed through the coding process, the codes are categorized and the themes are created. The themes described in the results of this study are focused on the five dimensions that this model proposes: (i) positive attitudes towards learning; (ii) acquisition and integration of knowledge; (iii) extending and refining knowledge; (iv) using knowledge meaningfully; and (v) productive habits of mind.

description: Galactic outflows are known to consist of several gas phases, however, so far the connection between these multiple phases has been investigated little and only in a few objects. In this paper, we analyse MUSE/VLT data of 26 local (U)LIRGs and study their ionised and neutral atomic phases. We also include objects from the literature to obtain a total sample of 31 galaxies with spatially resolved multi-phase outflow information. We find that the ionized phase of the outflows has on average an electron density three times higher than the disc ($n_{\rm e, disc}$ $\sim$ 145 cm$^{-3}$ vs $n_{\rm e, outflow}$ $\sim$ 500 cm$^{-3}$), suggesting that cloud compression in the outflow is more important that cloud dissipation. We find that the difference in extinction between outflow and disc correlates with the outflow gas mass. Together with the analysis of the outflow velocities, this suggests that at least some of the outflows are associated with the ejection of dusty clouds from the disc. This may support models where radiation pressure on dust contributes to driving galactic outflows. The presence of dust in outflows is relevant for potential formation of molecules inside them. We combine our data with millimetre data to investigate the molecular phase. We find that the molecular phase accounts for more than 60 $\%$ of the total mass outflow rate in most objects and this fraction is higher in AGN-dominated systems. The neutral atomic phase contributes of the order of 10 $\%$, while the ionized phase is negligible. The ionized-to-molecular mass outflow rate declines slightly with AGN luminosity, although with a large scatter.

description: As is well known, when an SU(2) operation acts on a two-level system, its Bloch vector rotates without change of magnitude. Considering a system composed of two two-level systems, it is proven that for a class of nonlocal interactions of the two subsystems including σ_i\otimesσ_j (with i,j \in {x,y,z}) and the Heisenberg interaction, the geometric description of the motion is particularly simple: each of the two Bloch vectors follows an elliptical orbit within the Bloch sphere. The utility of this result is demonstrated in two applications, the first of which bears on quantum control via quantum interfaces. By employing nonunitary control operations, we extend the idea of controllability to a set of points which are not necessarily connected by unitary transformations. The second application shows how the orbit of the coherence vector can be used to assess the entangling power of Heisenberg exchange interaction.

description: During the million years of evolution, gas dust and ice in protoplanetary disks can be chemically reprocessed. There are evidences that the gas-phase carbon and oxygen abundances are sub-solar in disks belonging to nearby star forming regions. These findings have a major impact on the composition of the primary atmosphere of giant planets (but it may also be valid for super-Earths and sub-Neptunes) as they accrete their gaseous envelopes from the surrounding material in the disk. In this study, we performed a thermo-chemical modelling analysis with the aim at testing how reliable and robust are the estimates of elemental abundance ratios based on (sub-)millimeter observations of molecular lines. We created a grid of disk models for the following different elemental abundance ratios: C/O, N/O and S/O, and, we computed the line flux of a set of carbon-, nitrogen and sulphur-bearing species, namely CN, HCN, NO, C$_{2}$H, c--C$_{3}$H$_{2}$, H$_{2}$CO, HC$_{3}$N, CH$_{3}$CN, CS, SO, H$_{2}$S and H$_{2}$CS, that have been detected with present (sub-)millimeter facilities such as ALMA and NOEMA. We find that the line fluxes, once normalized to the flux of the $^{13}$CO $J=2-1$ line, are sensitive to the elemental abundance ratios. On the other hand, the stellar and disk physical parameters have only a minor effect of the line flux ratios. Our results demonstrate that a simultaneous analysis of multiple molecular transitions is a valid approach to constrain the elemental abundance ratio in protoplanetary disks.

description: While the majority of approaches to the characterization of complex networks has relied on measurements considering only the immediate neighborhood of each network node, valuable information about the network topological properties can be obtained by considering further neighborhoods. The current work discusses on how the concepts of hierarchical node degree and hierarchical clustering coefficient (introduced in cond-mat/0408076), complemented by new hierarchical measurements, can be used in order to obtain a powerful set of topological features of complex networks. The interpretation of such measurements is discussed, including an analytical study of the hierarchical node degree for random networks, and the potential of the suggested measurements for the characterization of complex networks is illustrated with respect to simulations of random, scale-free and regular network models as well as real data (airports, proteins and word associations). The enhanced characterization of the connectivity provided by the set of hierarchical measurements also allows the use of agglomerative clustering methods in order to obtain taxonomies of relationships between nodes in a network, a possibility which is also illustrated in the current article.

A partir da análise de dados de pesquisa realizada junto a produtores do Pólo e através de estudo econométrico, são definidas as principais variáveis associadas à inadimplência e é estimada a regressão logística que explica o fenômeno no Pólo. Os resultados alcançados sugerem que a inadimplência no Pólo é influenciada positivamente por fatores como maior porte do produtor (exceto pequenos assentados de reforma agrária), realizar atividades extra-rurais e não realizar práticas agrícolas projetadas. Por outro lado, aspectos relacionados à maior idade do produtor, ser associado, ter bom relacionamento com órgãos de pesquisa e de assistência técnica, reaplicar os lucros na atividade, ter experiência de crédito com outras instituições financeiras, ser principiante na obtenção de financiamentos, e ter crédito adequado, ajudam a reduzir a inadimplência. As conclusões apontam para alternativas à solução dos entraves produtivos do Pólo, necessária ao desenvolvimento dessa região.-----------------------------------------------------------------------------------This work studies the use of agricultural credit in the irrigated fruit production of Petrolina- Juazeiro Pole. From the use of research data collected with the Pole producers and through the use of econometrical methodology, it is defined the main variable associated with the insolvency and are estimated the logistic regression that explains the phenomenon in the Pole. The results achieved suggest that the insolvency in the Pole is influenced positively by factors as bigger carry of the producer (except small settled of land reform), carry out other activities and do not carry out agricultural practices projected. However, aspects related to the biggest age of the producer, to be associated, have good relationship with organs of research and of technical aid, apply the profits in the activity, have experience of credit with other financial institutions, be beginner in the obtaining of financing and have adequate credit, help to reduce the insolvency. The conclusions aim for alternatives to the solution of the productive obstacles of the Pole, necessary to the development of that region.

Equivalently, a conditional is true if the antecedent is contained in the convex hull of the points that satisfy both the antecedent and consequent. Our result is then that every consistent formula without nested conditionals is satisfiable in a model based on a finite set of points in the plane. The proof relies on a result by Richter and Rogers showing that every finite abstract convex geometry can be represented by convex polygons in the plane.

description: Gaia is regularly producing Alerts on objects where photometric variability has been detected. The physical nature of these objects has often to be determined with the complementary observations from ground-based facilities. We have compared the list of Gaia Alerts (until 20181101) with archival LAMOST and SDSS spectroscopic data. The date of the ground-based observation rarely corresponds to the date of the Alert, but this allows at least the identification of the source if it is persistent, or the host galaxy if the object was only transient like a supernova. A list of Gaia Nuclear Transients from Kostrzewa-Rutkowska et al. (2018) has been included in this search also. We found 26 Gaia Alerts with spectra in LAMOST+SDSS labelled as stars (12 with multi-epoch spectra). A majority of them are CVs. Similarly 206 Gaia Alerts have associated spectra labelled as galaxies (49 with multi-epoch spectra). Those spectra were generally obtained on a date different from the Alert date, are mostly emission-line galaxies, leading to the suspicion that most of the Alerts were due to a SN. As for the GNT list, we found 55 associated spectra labelled as galaxies (13 with multi-epoch spectra). In two galaxies, Gaia17aal and GNTJ170213+2543, was the date of the spectroscopic observation close enough to the Alert date: we find a trace of the SN itself in their LAMOST spectrum, both classified here as a type Ia SN. The GNT sample has a higher proportion of AGNs, suggesting that some of the detected variations are also due to the AGN itself. Similar for Quasars, we found 30 Gaia Alerts but 68 GNT cases have single epoch quasar spectra, while 12 plus 23 have multi-epoch spectra. For ten out of these 35, their multi-epoch spectra show appearance or disappearance of the broad Balmer lines and also variations in the continuum, qualifying them as "Changing Look Quasars".

description: Experiments suggest that localization via self-trapping plays a central role in the behavior of equilibrated low mass particles in both liquids and in supercritical fluids. In the latter case, the behavior is dominated by the liquid-vapor critical point which is difficult to probe, both experimentally and theoretically. Here, for the first time, we present the results of path-integral computations of the characteristics of a self-trapped particle at the critical point of a Lennard-Jones fluid for a positive particle-atom scattering length. We investigate the influence of the range of the particle-atom interaction on trapping properties, and the pick-off decay rate for the case where the particle is ortho-positronium.

Troubled being and being troubled : subjectivity in the light of problems of the mind

description: Michel Foucault's archaeology of the silence of madness in the age of reason circumvents the discipline of psychiatry by refusing to contest the latter on its own terms. The success of Foucault's project of giving voice to the mad is achieved, however, at the expense of neglecting a long history of resistance to the silencing of madness, to which autobiographical writings by people said to be mad have contributed. The first phase of my dissertation focuses on mind-problem memoirs published since the late 1960s, a period in which an international psychiatric survivor movement has emerged. My readings of these memoirs examine how they elaborate ways of negotiating encounters with psychiatry in everyday life, and how they reveal the contingency of naturalized psychiatric practices. The second phase begins with the identification of certain questions that are not prominent among the concerns of political activists struggling to displace the psychiatric system. In the course of articulating a critique of narrative, I introduce the phrase "order of making sense" to describe a moral injunction—to respond and contribute to narrative reason—that acts as a regulative ideal. The third phase consists of fragmentary writing about personal experiences that, in spite of being framed by competing theoretical perspectives, destabilize boundaries. My increasing emphasis on the body, understood as a multiplicity of forces that are not amenable to the formation of coherent subjectivity, opens up the possibility of a revaluation of non-knowledge and the absence of work. The fourth phase concludes a dissertation whose unanticipated discontinuities are both caused by, and a mode of expression of, persistent mind problems. With the delineation of a post-Nietzschean aesthetic of the materialist sublime, the political strategies of psychiatric survivors, including my critique of narrative, are surpassed by the intensities of unproductive expenditure. Until mind problems are no longer pathologized as troubled being that stands in need of direction, the project of overcoming the condition of internal exile remains imperative. Yet it is the anti-project of exceeding sense—through an affirmation of being troubled by eternal recurrence—that most exposes the limits of the age of reason.

description: Recent advancements in artificial intelligence have enabled processing of larger inputs, leading everyday software developers to increasingly rely on chat-based large language models (LLMs) like GPT-3.5 and GPT-4 to detect vulnerabilities across entire files, not just within functions. This new development practice requires researchers to urgently investigate whether commonly used LLMs can effectively analyze large file-sized inputs, in order to provide timely insights for software developers and engineers about the pros and cons of this emerging technological trend. Hence, the goal of this paper is to evaluate the effectiveness of several state-of-the-art chat-based LLMs, including the GPT models, in detecting in-file vulnerabilities. We conducted a costly investigation into how the performance of LLMs varies based on vulnerability type, input size, and vulnerability location within the file. To give enough statistical power to our study, we could only focus on the three most common (as well as dangerous) vulnerabilities: XSS, SQL injection, and path traversal. Our findings indicate that the effectiveness of LLMs in detecting these vulnerabilities is strongly influenced by both the location of the vulnerability and the overall size of the input. Specifically, regardless of the vulnerability type, LLMs tend to significantly (p < .05) underperform when detecting vulnerabilities located toward the end of larger files, a pattern we call the 'lost-in-the-end' effect. Finally, to further support software developers and practitioners, we also explored the optimal input size for these LLMs and presented a simple strategy for identifying it, which can be applied to other models and vulnerability types. Eventually, we show how adjusting the input size can lead to significant improvements in LLM-based vulnerability detection, with an average recall increase of over 37% across all models.

Radiation conditions in relativistic interstellar flight

description: Radiation hazard on board of a relativistic rocket can be of internal and external origin. Because of its highest specific energy density, antimatter is considered to be the preferred rocket fuel for accelerating a multi-ton rocket up to relativistic speed. High-energy products of matter-antimatter annihilation (gamma-photons and meson radiation) can produce a severe radiation hazard for crew and electronics. Another factor that can stand against our pursuit to the stars is intense nucleons radiation produced by the oncoming relativistic headwind of interstellar gas and cosmic rays with their intensity increasing with rocket velocity. When a rocket accelerates to a relativistic speed, the rarefied interstellar gas of neutral and ionized atoms and molecules transforms into the oncoming flux of high-energy nucleons irradiating the rocket body and creating the severe radiation hazard. The oncoming flux of relativistic dust granules imposes a threat of mechanical damage to the rocket body.
