description: Gradient boosted trees and other regression tree models perform well in a wide range of real-world, industrial applications. These tree models (i) offer insight into important prediction features, (ii) effectively manage sparse data, and (iii) have excellent prediction capabilities. Despite their advantages, they are generally unpopular for decision-making tasks and black-box optimization, which is due to their difficult-to optimize structure and the lack of a reliable uncertainty measure. ENTMOOT is our new framework for integrating (already trained) tree models into larger optimization problems. The contributions of ENTMOOT include: (i) explicitly introducing a reliable uncertainty measure that is compatible with tree models, (ii) solving the larger optimization problems that incorporate these uncertainty aware tree models, (iii) proving that the solutions are globally optimal, i.e. no better solution exists. In particular, we show how the ENTMOOT approach allows a simple integration of tree models into decision-making and black-box optimization, where it proves as a strong competitor to commonly-used frameworks.

description: Does privatizing land improve child health and nutrition outcomes? We exploit a natural experiment in The Kyrgyz Republic following the collapse of socialism whereby the government rapidly liquidated state and collective farms containing 75 percent of agricultural land and distributed it to individuals, providing 99-year transferrable use rights. We use household surveys collected before, during, and after the reform and data on the spatial variation in the timing of privatization to identify its health and nutrition impacts. We find that children exposed to land privatization for longer periods of time accumulated significantly greater gains in height and weight, both critical measures of long-term health and nutrition. Children who benefited most from privatization were between the ages of 1 and 1.5 possibly due to protective effects of breastfeeding for children younger than a year old, and reduced vulnerability to health shocks at older ages. We find no evidence of significant gender differences in the effects of privatization.

description: Brazil is considered a world leader in the production of ethanol derived from sugarcane. It is questioned the existence of agricultural land that can shelter the expansion of the culture, without causing greater damages for the environment and for the society. Thus, the main objective of this research was to project the impact of an increase in the demand for sugarcane destined for ethanol on land use and on food production in Brazil. The methodology used was computable general equilibrium, with the incorporation of a land use module and a conversion cost among the different soil types. The results suggest that in Brazil sugarcane expansion will occur at the expense of crop and pasture areas. The impact on deforestation and the impact on food prices would be relatively small. And such changes could be softened by productivity gains on land. Acknowledgement :

description: This paper assesses the impact of participation in off-farm work on smartphone use, using an endogenous switching probit model and a survey of 493 rural Chinese households. The joint impacts of off-farm work participation and smartphone use on household income are also analyzed using a control function method. The results show that participation in off-farm work increases the probability of smartphone use significantly. Furthermore, we find that the household heads who engaged in off-farm activities and who were smartphone users earned 3,430 Yuan and 2,643 Yuan more per capita annual income, respectively, compared to their full-time farming and smartphone-free counterparts.

description: The Sello Manos Campesinas programme aims to make peasant farming visible by certifying four attributes that consumers recognise as proper from peasant farmers: i.e. originated from peasant farmers, artisanal production, healthy, and fostering local development. Two years after beginning operations, we collected information from focus groups in regards to the motivations of farmers for participating in the programme. With this information, we constructed a survey to evaluate those motivations and assess the effects and changes brought about by the seal on farmers businesses. This survey was applied to 100 farmers throughout the country. We identified three motivations for applying to be certified under the programme: improving sales, valuing the product and the production process, and receiving a personal recognition. However, for all practical purposes, their motivations were mainly for trading: raising product value, access new sales channels, and selling more products at a better price. Our results show that farmers actually use and promote the seal and that sales figures are promising, in spite of the scarce promotion of this seal to consumers. This situation could be explained as this seal makes customers trust the product, hence transforming their purchasing intentions.

description: This paper will build upon existing literature concerning Europe's post integration identity crisis to explore how, as sovereignty is pooled at the EU level, immigration increasingly is a mobilizing factor at the national level and a basis for national identity. This trend threatens to securitize the EU's political agenda and bring further integration to a screeching halt. The countries in the EU most concerned about immigration---Austria, Belgium, Denmark, Malta, Spain, and the United Kingdom---are selected from existing polling and quantitative analysis is conducted to assess why these countries appear more concerned about immigration than their neighbors. Country analysis will reveal the presence of practical challenges in some countries, particularly efforts to adjust to new immigration trends. In other countries examined that have not experienced significant changes in immigration flows in recent years, the growth of anti-immigrant sentiment may be a response to recent national traumas and the global security agenda. A common denominator between all of the countries reviewed, however, is negative media coverage of immigration and minorities, suggesting that comprehensive media reform is needed. Comparative analysis across countries indicates that far right parties do not necessarily do best in the most xenophobic environments. Instead, a variety of factors, including the country's political system and history appear to play a role in the development of the far right. Nonetheless, where political norms preclude far right parties from exercising power in any official capacity, increasing electoral success will allow far right parties to influence policy from the periphery.

For sustainable development in Taiwan, it is better to transform from traditional agriculture to value-added agriculture. Since enhancing the competitiveness of agriculture and pursuing inclusive growth, it would be necessary to pay attention to farmers value and consider both farmers and agricultural supply chain to implement the effective and comprehensive agricultural policy.

title: Medical care in English prisons 1770-1850
Creators: name: McRorie Higgins, Peter
Publisher: name: The Open University
Year: 2004

description: A consensus exists amongst both contemporary and present day students of penology that the prison reform process of the late-eighteenth century achieved one of its main objectives: the removal of a high risk of death from disease whilst incarcerated as an additional penalty to that imposed by the courts. Most observers are also in agreement that much of this desirable outcome was achieved by improving the prison environment - principally in respect of better standards of hygiene and a reduction in overcrowding. No such consensus exists amongst modem commentators as to the role of prison medical officers in this amelioration; indeed there has been a tendency to impute a negative role to these men. They are accused of being deeply involved in a system designed to control and dominate the lower orders of society, conniving in resultant deleterious effects on the health of their patients. This thesis provides the first detailed analysis of the effects of the day-to-day work of prison medical officers in the period 1770 to 1850. I have amassed information from several sources including: (1) journals kept by prison medical officers, (2) parliamentary enquiries, and (3) reports of prison inspectors. Some of these sources have never been previously studied; others have never been subjected to scrutiny from an informed medical standpoint. I have concluded that the prime factor motivating prison medical staff was the provision of care; their participation in a control system, although unavoidable, did not have an adverse effect on the standard of care. This care was, so far as can be ascertained, of the same standard as that provided to their private patients and although some treatment methods may seem primitive or even cruel to the modem reader, these were standard at the time. The practice of medicine involves the exercise of power; these men exercised that power in a correct and professional manner, caring for their patients to the best of their ability and ensuring maintenance of as healthy a prison environment as was possible.

We introduce the shore subdivision of simplicial complexes and use it to show an upper bound to this topological lower bound and to construct a strong Z_2-deformation retraction from the box complex (in the version introduced by Matousek and Ziegler) to the Lovasz complex. In the process, we analyze and clarify the combinatorics of the complexes involved and link their structure via several ``intermediate'' complexes.

description: We study correlated switchings of superconducting nanobridge probed with train of current pulses. For pulses with low repetition rate each pulse transits the superconducting bridge to normal state with probability $P$ independent of the outcomes in the preceding pulses. We show that with reduction of the time interval between pulses long range correlation between pulses occurs: stochastic switching in a single pulse rises temperature of the bridge and affects outcome of the probing for next pulses. As a result, an artificial intricate stochastic process with adjustable strength of correlation is produced. We identify regime where apparent switching probability exhibits the thermal hysteresis with discontinuity at a critical current amplitude of the probing pulse. This engineered stochastic process can be viewed as an artificial phase transition and provides an interesting framework for studying correlated systems. The process resembles the familiar transition from superconducting to normal state in the current-bias nanowire, proceeding through phase slip avalanche. Due to its extreme sensitivity on the control parameter, i.e. electric current, temperature or magnetic field, it offers opportunity for ultra-sensitive detection.

description: We present an X-ray study of the galaxy group RGH 80, observed by XMM-Newton. The X-ray emission of the gas is detected out to ~ 462h^{-1}_{50} kpc, corresponding to ~ 0.45 r_{200}. The group is relatively gas rich and luminous with respect to its temperature of 1.01 +/- 0.01 keV. Using the deprojected spectral analysis, we find that the temperature peaks at ~ 1.3 keV around 0.11r_{200}, and then decreases inwards to 0.83 keV at the center and outwards to ~ 70% of the peak value at large radii. Within the central ~ 60 kpc of the group where the gas cooling time is less than the Hubble time, two-temperature model with temperatures of 0.82 and 1.51 keV and the Galactic absorption gives the best fit of the spectra, with ~ 20% volume occupied by the cool component. We also derive the gas entropy distribution, which is consistent with the prediction of cooling and/or internal heating models. Furthermore, the abundances of O, Mg, Si, S, and Fe decrease monotonically with radius. With the observed abundance ratio pattern, we estimate that ~ 85% or ~ 72% of the iron mass is contributed by SN Ia, depending on the adopted SN II models.

description: Gammarus minus is a freshwater amphipod crustacean found in both cave and spring ecosystems. The cave populations have reduced eyes, longer antennae, larger body size and reduced pigmentation relative to the spring populations. In this study, I analyzed the opsin gene sequence from 60 cave and 99 spring individuals for determining the opsin gene sequence variation between the cave and spring populations. I also studied the difference in opsin expression between the two populations. My analysis revealed that there is no significant difference in opsin gene variation between the two populations. I also failed to detect any evidence of neutral evolution of opsin within the cave populations. However, there was significant difference in opsin expression between the cave and spring populations. These data suggest that opsin in the cave G. minus is required for survival and could probably be playing a role unrelated to vision.

description: Citation recommendation describes the task of recommending citations for a given text. Due to the overload of published scientific works in recent years on the one hand, and the need to cite the most appropriate publications when writing scientific texts on the other hand, citation recommendation has emerged as an important research topic. In recent years, several approaches and evaluation data sets have been presented. However, to the best of our knowledge, no literature survey has been conducted explicitly on citation recommendation. In this article, we give a thorough introduction into automatic citation recommendation research. We then present an overview of the approaches and data sets for citation recommendation and identify differences and commonalities using various dimensions. Last but not least, we shed light on the evaluation methods, and outline general challenges in the evaluation and how to meet them. We restrict ourselves to citation recommendation for scientific publications, as this document type has been studied the most in this area. However, many of the observations and discussions included in this survey are also applicable to other types of text, such as news articles and encyclopedic articles.

description: We present a circuit model to describe the electron transport through a domain wall in a ferromagnetic nanowire. The domain wall is treated as a coherent 4-terminal device with incoming and outgoing channels of spin up and down and the spin-dependent scattering in the vicinity of the wall is modelled using classical resistances. We derive the conductance of the circuit in terms of general conductance parameters for a domain wall. We then calculate these conductance parameters for the case of ballistic transport through the domain wall, and obtain a simple formula for the domain wall magnetoresistance which gives a result consistent with recent experiments. The spin transfer torque exerted on a domain wall by a spin-polarized current is calculated using the circuit model and an estimate of the speed of the resulting wall motion is made.

description: The hypotelminorheic is a type of perched aquifer with an unknown geographic extent. Depending on the local topography, groundwater from one hypotelminorheic may flow to the surface forming a single seep, or to several surface locations forming multiple seeps. In order to infer the boundaries of the hypotelminorheic, I analyzed the population structure of a subterranean seep amphipod species. I analyzed a 628 bp region of mtDNA corresponding to the cytochrome oxidase c subunit I gene from 118 specimens of S. tenuis potomacus , collected from 9 seeps along the George Washington Memorial Parkway. Pairwise comparisons among sites (uncorrected "p" = 0.7 -- 12.7%) and the nested Glade phylogeographic analysis suggested that hypotelminorheic habitats are fragmented. However, population subdivision (within site uncorrected "p" = 0 -- 13.06%) found at many of the sites suggests that hypotelminorheic habitats have a dynamic extent that fluctuates with the water table, forming temporary corridors between hypotelminorheics.

Magnetic Branes in Gauss-Bonnet Gravity

Year: 2003
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We present two new classes of magnetic brane solutions in Einstein-Maxwell-Gauss-Bonnet gravity with a negative cosmological constant. The first class of solutions yields an $(n+1)$-dimensional spacetime with a longitudinal magnetic field generated by a static magnetic brane. We also generalize this solution to the case of spinning magnetic branes with one or more rotation parameters. We find that these solutions have no curvature singularity and no horizons, but have a conic geometry. In these spacetimes, when all the rotation parameters are zero, the electric field vanishes, and therefore the brane has no net electric charge. For the spinning brane, when one or more rotation parameters are non zero, the brane has a net electric charge which is proportional to the magnitude of the rotation parameter. The second class of solutions yields a spacetime with an angular magnetic field. These solutions have no curvature singularity, no horizon, and no conical singularity. Again we find that the net electric charge of the branes in these spacetimes is proportional to the magnitude of the velocity of the brane. Finally, we use the counterterm method in the Gauss-Bonnet gravity and compute the conserved quantities of these spacetimes.

title: The diagnosis and pathophysiology of tuberculous meningitis in Vietnamese adults
Creators: name: Thwaites, Guy Edward
Publisher: name: The Open University
Year: 2004

description: Approximately 30% of people with tuberculous meningitis (TBM) die despite modem treatment. Survival is dependent upon early treatment but diagnosis is difficult: the clinical features are non-specific, conventional bacteriology is widely regarded as insensitive, and newer diagnostic tests are incompletely evaluated. In addition, the pathogenesis of TBM remains so poorly understood that prospects for new interventions to improve outcome are few.
 This thesis examines the diagnosis and pathophysiology of TBM in adults admitted to an infectious disease hospital in Ho Chi Minh City, Vietnam. The aim was to address three questions: what is the best method for distinguishing TBM from other central nervous system disorders, how does disease pathophysiology relate to treatment and clinical outcome, and what other variables influence prognosis?
 Three methods for the diagnosis of TBM were studied: clinical, bacteriological and molecular. A diagnostic rule developed from five clinical features predictive of TBM was 86% sensitive and 79% specific when applied prospectively. A bacteriological diagnosis of TBM was confirmed in 107/132 (81%) adults: acid-fast bacilli were seen in 58% and cultured from 71%. Volume of CSF, duration of symptoms, CSF neutrophils, lactate and glucose all predicted bacteriological confirmation. The sensitivity and specificity of CSF Ziehl-Neelsen stain (52% and 100%) was greater than nucleic acid amplification (Gen-Probe Amplified Mycobacterium tuberculosis Direct test) (38% and 9 9%), although the combined performance of these tests on serial samples detected 83% of cases.
 The pathogenesis of TBM was investigated by identifying clinical and molecular markers of poor outcome. Treatment before the onset of coma independently predicted survival, and death was associated with high CSF concentrations of lactate, low numbers of white cells, in particular neutrophils, and low CSF glucose. CSF lactate concentration is a good indicator of disease severity and CSF bacterial load, and neutrophils may have a hitherto unreported protective role.

description: Quantum error correction protocols have been developed to offset the high sensitivity to noise inherent in quantum systems. However, much is still unknown about the behaviour of a quantum error-correcting code under general noise, including noisy measurements. This lack of knowledge is largely due to the computational cost of simulating quantum systems large enough to perform nontrivial encodings. In this paper, we develop general methods for incorporating noisy measurement operations into simulations of quantum error-correcting codes and show that measurement errors on readout qubits manifest as a renormalization on the effective logical noise. We also derive general methods for reducing the computational complexity of calculating the exact effective logical noise by many orders of magnitude. This reduction is achieved by determining when different recovery operations produce equivalent logical noise. These methods could also be used to better approximate soft decoding schemes for concatenated codes or to reduce the size of a lookup table to speed up the error correction step in implementations of quantum error-correcting codes. We give examples of such reductions for the three-qubit, five-qubit, Steane, concatenated, and toric codes.

description: Epidermal growth factor receptor (EGFR) signaling plays a substantial role in learning and memory. The upregulation of EGFR has been embroiled in the pathophysiology of Alzheimer's disease (AD). Nevertheless, most of EGFR-tyrosine kinase inhibitors (EGFR-TKIs) have been extensively studied for non-CNS diseases such as cancer and rheumatoid arthritis. TKIs targeting-based research in neurodegenerative disorders sounds to be lagging behind those of other diseases. Hence, this study aims to explore the molecular signaling pathways and the efficacy of treatment with lapatinib ditosylate (LAP), as one of EGFR-TKIs that has not yet been investigated in AD, on cognitive decline induced by ovariectomy (OVX) with chronic administration of D-galactose (D-gal) in female Wistar albino rats. OVX rats were injected with 150 mg/kg/day D-gal ip for 8 weeks to induce AD. Administration of 100 mg/kg/day LAP p.o. for 3 weeks starting after the 8th week of D-gal administration improved memory and debilitated histopathological alterations. LAP decreased the expression of GFAP, p-tau, and Aβ 1-42. Besides, it reduced EGFR, HER-2, TNF-α, NOX-1, GluR-II, p38 MAPK, and p-mTOR. LAP increased nitrite, and neuronal pro-survival transduction proteins; p-PI3K, p-AKT, and p-GSK-3β levels. Taken together, these findings suggest the role of LAP in ameliorating D-gal-induced AD in OVX rats via activating the pro-survival pathway; PI3K-Akt-GSK-3β, while inhibiting p-mTOR, NOX-1, and p38 MAPK pathways. Moreover, this research offered a significant opportunity to advance awareness of the repositioning of TKI anti-cancer drugs for the treatment of AD.
Mapping the hypotelminorheic habitat by studying the population structure of amphipods in seeps
Creators: name: Kavanaugh, Karen
Publisher: name: American University

description: The hypotelminorheic is a type of perched aquifer with an unknown geographic extent. Depending on the local topography, groundwater from one hypotelminorheic may flow to the surface forming a single seep, or to several surface locations forming multiple seeps. In order to infer the boundaries of the hypotelminorheic, I analyzed the population structure of a subterranean seep amphipod species. I analyzed a 628 bp region of mtDNA corresponding to the cytochrome oxidase c subunit I gene from 118 specimens of S. tenuis potomacus , collected from 9 seeps along the George Washington Memorial Parkway. Pairwise comparisons among sites (uncorrected "p" = 0.7 -- 12.7%) and the nested Glade phylogeographic analysis suggested that hypotelminorheic habitats are fragmented. However, population subdivision (within site uncorrected "p" = 0 -- 13.06%) found at many of the sites suggests that hypotelminorheic habitats have a dynamic extent that fluctuates with the water table, forming temporary corridors between hypotelminorheics.

description: We calculate the long time and distance asymptotics of the one-particle correlation functions in the model of impenetrable spin 1/2 fermions in 1+1 dimensions. We consider the spin disordered zero temperature regime, which occurs when the limit $T\to0$ is taken at a positive chemical potential. The asymptotic expressions are found from the asymptotic solution of the matrix Riemann-Hilbert problem related to the determinant representation of the correlation functions.

description: The growing trends in automation, Internet of Things, big data and cloud computing technologies have led to the fourth industrial revolution (Industry 4.0), where it is possible to visualize and identify patterns and insights, which results in a better understanding of the data and can improve the manufacturing process. However, many times, the task of data exploration results difficult for manufacturing experts because they might be interested in analyzing also data that does not appear in pre-designed visualizations and therefore they must be assisted by Information Technology experts. In this paper, we present a proposal materialized in a semantic-based visual query system developed for a real Industry 4.0 scenario that allows domain experts to explore and visualize data in a friendly way. The main novelty of the system is the combined use that it makes of captured data that are semantically annotated first, and a 2D customized digital representation of a machine that is also linked with semantic descriptions. Those descriptions are expressed using terms of an ontology, where, among others, the sensors that are used to capture indicators about the performance of a machine that belongs to a Industry 4.0 scenario have been modeled. Moreover, this semantic description allows to: formulate queries at a higher level of abstraction, provide customized graphical visualizations of the results based on the format and nature of the data, and download enriched data enabling further types of analysis.

description: This work presents a procedure to extract morphological information from neuronal cells based on the variation of shape functionals as the cell geometry undergoes a dilation through a wide interval of spatial scales. The targeted shapes are alpha and beta cat retinal ganglion cells, which are characterized by different ranges of dendritic field diameter. Image functionals are expected to act as descriptors of the shape, gathering relevant geometric and topological features of the complex cell form. We present a comparative study of classification performance of additive shape descriptors, namely, Minkowski functionals, and the nonadditive multiscale fractal. We found that the proposed measures perform efficiently the task of identifying the two main classes alpha and beta based solely on scale invariant information, while also providing intraclass morphological assessment.

description: Our Opposite Gravities seeks to explore an individual's awakening to an awareness of the universe. The first-person speaker is often the observer, watching how themes of nature, identity, history, tradition, and emotion contribute to the reactions that ultimately comprise the human experience. By dividing the work, each section serves to focus on a particular method of examination. "Niggunim," the Hebrew word for syllable-based songs, utilizes language to create a melody of invocation. "Rules of the Moon" seeks out an understanding of the laws we abide in order to relate to the cosmos. "Perspectives of Satellites" analyzes individual views, both macro and microscopic, while "Things Pinned to Sleeves" serves as a culmination of all these thoughts, the realization of the absurd, horrible beauty of life.

description: We study the baryonic fluctuations from second to eighth order involving electric charge, baryon number and strangeness below the quark-gluon plasma crossover and numerically known from lattice QCD calculations. By considering a particular realization of the Hadron Resonance Gas model, we provide evidence on the dominant role of quark-diquark degrees of freedom to describe excited baryonic resonances. After proving by means of suitable Polyakov loop correlators that the quark-diquark and the quark-antiquark forces coincide, $V_{\bar q q } (r) = V_{\bar q D } (r) + \textrm{const}$, we find that the corresponding susceptibilities can be saturated with excited baryonic states in a quark-diquark model picture.
