Unit-Cell Approximation for Diblock-Copolymer Brushes Grafted to Spherical Particles

This paper examines the equilibrium phase behavior of thin diblock-copolymer films tethered to a spherical core, using numerical self-consistent field theory (SCFT). The computational cost of the calculation is greatly reduced by implementing the unit-cell approximation (UCA) routinely used in the study of bulk systems. This provides a tremendous reduction in computational time, permitting us to map out the phase behavior more extensively and allowing us to consider far larger particles. The main consequence of the UCA is that it omits packing frustration, but evidently the effect is minor for large particles. On the other hand, when the particles are small, the UCA calculation can be readily followed up with the full SCFT, the comparison to which conveniently allows one to quantitatively assess the effect of packing frustration.
Hidden complexity of lichen symbiosis

Lichens are tremendously diverse physical outcomes of symbiotic relationships involving fungi, algae and bacteria. This thesis aims to give insight into the functionality, composition and reproduction of lichens from the fungal perspective. When previous results from a barcoding study were re-evaluated, no support for a free-living life phase of Cladonia mycobionts could be found. Genomic and transcriptomic data were used to identify the fungal partners in thalli, and a fluorescent in situ hybridization (FISH) method for the simultaneous visualization of the different fungi was developed. This approach led to the discovery of previously unknown basidiomycetes, Cyphobasidium spp. , which are widespread components of the cortex of lichens in Parmeliaceae. In some cases, the abundance of Cyphobasidium correlates with previously unexplained phenotypic variation of the lichens. In the case example Bryoria capillaris, Cyphobasidium yeasts are the dominant cells in the cortex and hence the fungus that meets the eye when looking at the lichen. With the help of hologenomic data and FISH, it could also be shown that Tremella lethariae, a lichenicolous heterobasidiomycete known to induce galls on Letharia, is dimorphic and frequently occupies the cortex of asymptomatic Letharia thalli in its anamorphic state. Finally, genomic and transcriptomic data was used to investigate the mating system of the genus Letharia, which includes species with different reproductive strategies. All studied Letharia species have a heterothallic mating system, meaning they need to find a compatible mate in order to sexually reproduce. Thus, the variation of reproduction strategies within the genus cannot be explained only by the mating system of the Letharia mycobiont. Our data on the mating-type ratios indicates that no potential for sexual reproduction exists for the red-listed L. vulpina in Sweden, as only one mating type is found in the populations. The roles the secondary fungi have in the symbiosis is not yet fully understood. However, the results indicate that we should not automatically assume that some of the organisms are negligible for the function of the holobiont, or that all functions assigned to fungal origin are conducted by the primary mycobiont. Altogether, the findings presented in this thesis support the view of lichens as a community of bionts with complex interactions and calls for a more holistic approach for the study of the symbiosis.

Investigating the relationship between airborne laser scanning derived forest canopy vertical structure and Landsat ETM+ derived indices

Vertical arrangement of forest foliage and branches are fundamental plant traits that determine, amongst others, habitat suitability, fire behaviour and provision of ecosystem services. LiDAR has been shown to provide accurate measurement of three-dimensional (3D) vegetation structure; however the cost of acquisition at the regional scale can be prohibitively expensive. Conversely, passive remote sensing allows the spatially continuous attribution of forests at a fraction of the cost but without direct measurement of 3D structure. We present a comparison of Landsat ETM+ derived vegetation indices and their ability to infer LiDAR derived vertical forest structure. Discrete return airborne laser scanning data was acquired over ~7500 ha, across three structurally diverse native forested landscapes in Victoria, Australia. Forest vertical structural heterogeneity was characterised at 280 plots (0.04 ha) using three metrics; foliage height diversity (FHD) (MacArthur and Horn, 1969), coefficient of variation (Cv) of return height (Bolton et al., 2013) and a new technique that estimates the number of canopy layers (CL). Three coincident Landsat ETM+ images were pre-processed to surface reflectance (Flood et al., 2013) and Normalised Difference Vegetation Index (NDVI), Enhanced Vegetation Index (EVI), tasselled cap indices (greenness, brightness and wetness) (Huang et al., 2002) and first and second principal components (PC1 and PC2 respectively) were computed. OLS regression was then used to analyse the relationship between structural and spectral variables. Explained variance (R2) is greatest for NDVI > wetness > PC1 > brightness > greenness > EVI > PC2 for all three dependent variables; where NDVI explains 64% (p â‰¤0.05) of variance in FHD. FHD consistently returns greater correlation coefficients with all spectral indices; it is suggested this is due to the nonlinear relationship between FHD and canopy height (Weishampel et al., 2007) and the subsequent strong relationship between canopy height and spectral indices (Cohen and Spies, 1992; Hudak et al., 2002). CV and CL are less well explained by spectral indices (R2 â‰¤0.38) and this is likely caused by the inability to infer vertical structure from medium resolution Landsat ETM+; indices derived from higher resolution imagery might prove more useful (Pasher and King, 2011). Furthermore, sub-setting datasets by height or canopy cover does not improve regression performance particularly for tall (>30 m) and dense (canopy cover >50%) forests.
Effects of climate change on deepwater oxygen and winter mixing in a deep lake (Lake Geneva): Comparing observational findings and modeling

Low concentrations of dissolved oxygen remain a global concern regarding the ecological health of lakes and reservoirs. In addition to high nutrient loads, climate‐induced changes in lake stratification and mixing represent additional anthropogenic menace resulting in decreased deepwater oxygen levels. The analysis of 43 years of monitoring data from Lake Geneva shows no decreasing trend neither in the areal hypolimnetic mineralization rate nor in the extent of hypoxia. Instead, hypoxic conditions are predominantly controlled by deep mixing in winter and much less by the trophic variations over the past decades. To reproduce winter mixing, the one‐dimensional hydrodynamic model SIMSTRAT was specially adapted to deep lakes and run for several climate scenarios. The simulations predicted a decrease in the maximum winter mixing depth from an average of ∼172 m for 1981–2012 to ∼136 m and ∼127 m in response to predicted atmospheric temperatures between 2045–2076 and 2070–2101 according to Intergovernmental Panel on Climate Change scenarios. Concurrently, events with complete homogenization of temperature and oxygen in winter will decrease by ∼50%. Consequently, the hypolimnetic oxygen concentrations will significantly decrease. These results demonstrate that changes in deep mixing can have stronger impact than eutrophication on the deepwater oxygen levels of oligomictic lakes.
GRAVIMETRIC DENSIFICATION IN THE STATE OF SÃO PAULO AIMING A GEOID MODEL

ABSTRACT. Gravitydata coverage is quite complete in Sao Paulo state for a 5’ resolution. In addition, field works have been conducted to fill in gaps around the state. These efforts are the results of the Fundac¸˜ao de Amparo `a Pesquisa do Estado de S˜ao Paulo (FAPESP) Thematic Project that seeks to achieve the establishment of a geoid model, a height system, and the study of mean sea level. This paper presents a comparison between two geoidal height models; the first with information available up to 2008 (beginning of the project) and the second including all data collected. Both models have been derived using the modified Stokes integral through the FFT technique. The SHGEO package was used to derive the Helmert gravity anomalies, while the EGM2008 model was selected as a reference geopotential field restricted to degree and order 150, to obtain the long and medium wavelength components. The model was validated using the geoidal heights from 170 GPS observations on Bench Marks of the spirit leveling network. The corresponding height anomalies derived from recent geopotential models (GO CONS GCF 2 TIM R2, GOCO02S and EIGEN-6C) were also compared with the same quantities at the points of leveling, besides the official Brazilian model, MAPGEO2010. The findings showed that GEOIDSP2011 displayed better consistency with respect for the GPS/leveling than GEOIDSP2008 and the geopotential models. Keywords: geodesy, geoid, geopotential model. RESUMO. O estado de Sao Paulo possui uma cobertura bastante completa de dados gravimetricos para uma resolucao de 5’. Alem disso, trabalhos de campo estao sendo realizados com o objetivo de preencher os vazios no entorno do estado. Os recentes esforcos nos levantamentos sao devido ao Projeto Tematico da FAPESP que tem, entre outras finalidades o estabelecimento de um modelo geoidal, alem do estudo sobre sistemas de altitude e monitoramento do nivel medio dos mares. Este artigo apresenta a comparacao entre doismodelos de alturas geoidais; o primeiro cominformacoes disponiveis ate 2008 (fase inicial do projeto) e o segundo incluindo os dados coletados ate o momento. Ambos os modelos foram calculados utilizando a integral modificada de Stokes por meio da tecnica FFT. O pacote computacional SHGEO foi empregado para determinar as anomalias de gravidade de Helmert, enquanto omodelo do geopotencial EGM2008 restrito ate grau e ordem 150 foi selecionado para obter as componentes de longo e medio comprimento de onda. Osmodelos foramvalidados a partir da comparacao das alturas geoidais em 170 marcos da rede de nivelamento onde observacoes GPS foram conduzidas. As anomalias de altura dos modelos mais recentes do geopotencial (GO CONS GCF 2 TIM R2, GOCO02S e EIGEN-6C) tambem foram comparadas com as mesmas grandezas nos pontos de nivelamento, alem do modelo oficial brasileiro, o MAPGEO2010. Os resultados mostraram melhor consistencia na comparacao com os pontos GPS/nivelamento do modelo GEOIDSP2011 em relacao ao GEOIDSP2008 e os modelos do geopotencial.

A Novel Evolutionary Automatic Data Clustering Algorithm using Teaching-Learning-Based Optimization

Teaching-Learning-Based Optimization (TLBO) is a contemporary algorithm being used as a novel, trustworthy, precise and robust optimization technique for global optimization over continuous spaces both constrained and unconstrained tribulations. TLBO works on the beliefs of teaching and learning and clearly justifies this pedagogy by highlighting the effect of power of a teacher on the output of learners in a class. This paper, explores the applicability of k-means unsupervised learning into TLBO with two endeavors, i.e. to automatically find the optimal number of naturally classified partition in the data without any prior information, and the other is to inspect the naturally classified partitions with cluster validity indices (CVIs) and endorse the goodness of clusters. The proposed automatic clustering algorithm using TLBO (AutoTLBO) pursues a novel evolutionary approach by incorporating the simple k-means algorithm and CVIs into TLBO to configure and validate automatic natural partition in datasets. This algorithm retains the core ideology of clustering to minimize the inter cluster distances and maximize the intra cluster distances among the data. Experimental analysis substantiates the openness of the anticipated method after inspecting suavest panoramic rendering over artificial and benchmark datasets.
CAFFEIC ACID PREVENTS LIPID PEROXIDATION AND ANTIOXIDANT STRESS IN CHRONIC UVB EXPOSED MICE SKIN

In this study, we analyzed antioxidants status of caffeic acid on chronic UVB exposed skin in Swiss albino mice. We found that the completion of chronic UVB exposure (210 days) mice skin shows increased lipid peroxidation and depletion of enzymatic and non-enzymatic antioxidants. Treatment of caffeic acid prevents lipid peroxidation and depletion of antioxidants in chronic UVB exposed mouse skin. Further caffeic inhibits the expressions of COX-2 and ODC in UVB exposed mice. Thus, prevention of chronic UVB induced COX-2 and ODC expressions counteracted by the free radical scavenging potential of caffeic acid. Article History
Do cognitive styles affect psychophysical tasks performance

Background. In order to deepen understanding of signal detection/discrimination processes we have to focus on highlighting individual differences in observers’ sensory performance due to the contribution of various variables of personality and cognition spheres. The purpose of our study was to test cognitive style factors (augmenting-reducing, levelling-sharpening, flexibility-rigidity of cognitive control, equivalence range, and focusing-scanning) influencing performance of psychophysical tasks. Methods. Ninety participants performed a set of cognitive style tests as well as two psychophysical tasks on visual signal detection (‘yes-no’) and loudness discrimination (‘same-different’). The duration of visual pattern presentation and difference between pairs of auditory stimuli were used to provide task’s difficulty level, and therefore the level of uncertainty. Results. Data analysis showed several effects of cognitive styles on psychophysical tasks performance indices, in particular: sensory sensitivity, RT and its stability, and response confidence. According to our results, each style is related to its own benefits and advantages in observer’s overall productivity. Furthermore, the contribution of cognitive styles differed depending on task’s type and difficulty level. Conclusions. Our results support current findings, considering cognitive styles as playing a regulative role in cognitive activity. Hence, they could be acknowledged as tools, mediating individual strategies, representing different ways of coping with perceptual uncertainty. © 2017 Published by Future Academy www.FutureAcademy. org.UK
Going Deeper: a Taxonomy of 3D on the Tabletop

Extending the tabletop to the third dimension has the potential to improve the quality of applications involving 3D data and tasks. Recognizing this, a number of researchers have proposed a myriad of display and input metaphors. However a standardized and cohesive approach has yet to evolve. Furthermore, the majority of these applications and the related research results are scattered across various research areas and communities, and lack a common framework. In this paper, we survey previous 3D tabletops systems, and classify this work within a newly defined taxonomy. We then discuss the design guidelines which should be applied to the various areas of the taxonomy. Our contribution is the synthesis of numerous research results into a cohesive framework, and the discussion of interaction issues and design guidelines which apply. Furthermore, our work provides a clear understanding of what approaches have been taken, and exposes new routes for potential research, within the realm of interactive 3D tabletops.
A NOVEL SPUTTERED MEDIUM BETA CAVITY FOR ALPI

The installed medium β ALPI cavities were produced by Nb sputtering on old Cu substrates, which were originally Pb plated. The cavity renew could practically double the previous average operational accelerating field but the performance obtained in high β resonators, whose Cu bases were designed to be sputtered, could not be reached [1, 2]. To overcome this performance gap, we designed, built and tested a novel medium β cavity, which has the shorting plate rounded as in high β cavities, while the beam ports are obtained by plastic deformation of the outer conductor instead of being brazed to the cavity body as in the previous medium β QWRs. The paper describes cavity design, substrate construction technology, surface treatments and results of the first resonator cold test.
Classification : Primary 62 C 99 , secondary 62 C 10 , 62 C 20 , 62 J 05

The paper deals with recovering an unknown vector β ∈ R based on the observations Y = Xβ + ǫξ and Z = X + σζ, where X is an unknown n×p matrix with n ≥ p, ξ ∈ R is a standard white Gaussian noise, ζ is a n× p matrix with i.i. d. standard Gaussian entries, and ǫ, σ ∈ R are known noise levels. It is assumed that X has a large condition number and p is large. Therefore, in order to estimate β, the simple Tikhonov-Phillips regularization (ridge regression) with a datadriven regularization parameter is used. For this estimation method, we study the effect of noise σζ on the quality of the recovering of Xβ using concentration inequalities for the prediction error.
A study of sharing definitions in thread-local heaps (Position Paper)

With the advent of larger heaps, multi-core processors and NUMA architectures, garbage collection scalability is evermore important. Shared memory is an important bottleneck and stress on shared memory can be reduced by using Thread-local heaps. Thread-local heaps provide a promising solution to this challenge, distinguishing between local objects that do not escape their allocating thread and shared objects that do. This allows a new type of collection that requires a single thread’s co-operation and affords more intelligent object placement in the heap. We examine options for their design and suggest a new design.
An Evaluation of the Determinants and Implications of Panel Attrition in the National Income Dynamics Survey (2008‐2010)

Panel surveys offer a valuable tool for researchers to explore the dynamics underlying individual and household behaviours. The Achilles heel of panel data is attrition. This paper examines the determinants and implications of attrition in the first two waves of South Africa's National Income Dynamics Survey. Multivariate tests in labour market and health specifications show that there is some moderate evidence of attrition bias in estimated coefficients based on the non-attriting sample. This bias can be seen in labour market specifications, in particular for men, and for Africans, and to a much lesser degree in health specifications, in particular for small samples of Whites. Researchers should take care when using the panel data set to generalise to the overall population.
Financial CEMATT Method: a New Approach for Performance Assessment using Accounting Information

The paper highlights the issue of accounting information as source for determining the financial position, with the customization on a case study in the clothing industry. This study provides an integrated approach to how the financial position can be determined by the financial CEMATT model for a case study based on 108 medium-sized companies selected according to their turnover in the clothing industry in Romania in 2014. The results of the study were encouraging, the most analyzed companies being within the area of financial balance; moreover, none of the companies analysed, in terms of financial diagnosis, wasnâ€™t registered in the critical region, that lead a company to bankruptcy
Singular Value Decomposition and Ligand Binding Analysis

Singular values decomposition (SVD) is one of the most important computations in linear algebra because of its vast application for data analysis. It is particularly useful for resolving problems involving least-squares minimization, the determination of matrix rank, and the solution of certain problems involving Euclidean norms. Such problems arise in the spectral analysis of ligand binding to macromolecule. Here, we present a spectral data analysis method using SVD (SVD analysis) and nonlinear fitting to determine the binding characteristics of intercalating drugs to DNA. This methodology reduces noise and identifies distinct spectral species similar to traditional principal component analysis as well as fitting nonlinear binding parameters. We applied SVD analysis to investigate the interaction of actinomycin D and daunomycin with native DNA. This methodology does not require prior knowledge of ligand molar extinction coefficients (free and bound), which potentially limits binding analysis. Data are acquired simply by reconstructing the experimental data and by adjusting the product of deconvoluted matrices and the matrix of model coefficients determined by the Scatchard and McGee and von Hippel equation.
MUSE: a second-generation integral-field spectrograph for the VLT

We describe MUSE (Multi Unit Spectroscopic Explorer), a second-generation integral-field spectrograph for the VLT, operating in the visible and near IR wavelength range. It combines a 1' x 1' Field of View with the improved spatial resolution (0.2") provided by adaptive optics and covers a large simultaneous spectral range (0.48 - 1 μm). With this unique combination of capabilities, MUSE has a wide domain of application, and a large discovery potential. It will provide ultra deep fields with a limiting magnitude for spectroscopy of R = 28. After a brief presentation of the scientific case and the derived instrument requirements, we will focus on the MUSE optical design, including the overall architecture, the major trade-off that were conducted in order to optimize the cost and performance, and a provisional implementation scheme of the instrument on the VLT Nasmyth platform. Then the most important optical subsystems (as the 3 x 8 Field-splitter, the Image Slicers and the Spectrometers) are described. One of MUSE special feature is the impressive number of Image Slicer and Spectrometer modules which must be manufactured, that is 24. The realization of such series has been studied in collaboration with an industrial company. Finally a preliminary estimation of the expected performance and a technological development program in order to secure the realization of the critical optical subsystems will be presented.
