description: The distance dependence and atomic-scale contrast observed in nominal contact potential difference (CPD) signals recorded by KPFM on surfaces of insulating and semiconducting samples, have stimulated theoretical attempts to explain such effects. We attack this problem in two steps. First, the electrostatics of the macroscopic tip-cantilever-sample system is treated by a finite-difference method on an adjustable nonuniform mesh. Then the resulting electric field under the tip apex is inserted into a series of atomistic wavelet-based density functional theory (DFT) calculations. Results are shown for a realistic neutral but reactive silicon nano-scale tip interacting with a NaCl(001) sample. Bias-dependent forces and resulting atomic displacements are computed to within an unprecedented accuracy. Theoretical expressions for amplitude modulation (AM) and frequency modulation (FM) KPFM signals and for the corresponding local contact potential differences (LCPD) are obtained by combining the macroscopic and atomistic contributions to the electrostatic force component generated at the voltage modulation frequency, and evaluated for several tip oscillation amplitudes A up to 10 nm. Being essentially constant over a few Volts, the slope of atomistic force versus bias is the basic quantity which determines variations of the atomic-scale LCPD contrast. Already above A = 0.1 nm, the LCPD contrasts in both modes exhibit almost the same spatial dependence as the slope. In the AM mode, this contrast is approximately proportional to $A^{-1/2}$, but remains much weaker than the contrast in the FM mode, which drops somewhat faster as A is increased. These trends are a consequence of the macroscopic contributions to the KPFM signal, which are stronger in the AM-mode and especially important if the sample is an insulator even at sub-nanometer separations where atomic-scale contrast appears.

Nonlinear mechanical behavior of automotive airbag fabrics : an experimental and numerical investigation
Creators: name: Zacharski, Steven Edward
Publisher: name: University of British Columbia
Year: 2010

description: Over the past two decades, the airbag has become an essential safety device in automobiles. The airbag cushion is composed of a woven fabric which is rapidly inflated during a car crash. The airbag dissipates the passenger’s kinetic energy thereby reducing injury through biaxial stretching of the fabric bag and escaping gas through vents. Therefore, the performance of the airbag is greatly influenced by the mechanical properties of the fabric. Unlike traditional engineering materials, airbag fabrics are composed of discrete constituents and have highly nonlinear mechanical behavior that arises from both geometric deformations and material nonlinearity. Henceforth, airbag designers are forced to make simplified assumptions regarding the mechanical behavior of the fabric cushion. This incontrovertibly limits designers in taking advantage of the full potential of the fabric system. In order to optimize the airbag design, improve deployment simulations and overall dependability, a more sophisticated approach is needed. In this study, a simple unit cell model representing a single crossover of two orthogonal woven yarns is developed to simulate the in-plane mechanical behavior of both coated and uncoated plain weave airbag fabrics under multiple states of stress. Since the structural analysis of the deployment of the airbag is performed using the finite element method, the proposed mechanistic model is implemented as a User-Material-Model in the commercial code LS-DYNA. Here, the unit cell model represents the constitutive behavior of a continuum membrane. The approach results in capturing, in detail, the discrete nature of the fabric while retaining the computational efficiency of simple membrane formulation compared to explicitly modeling each yarn within the fabric. The procedure to calibrate the model inputs, namely the yarn geometric and mechanical properties for a given fabric is detailed. The sensitivity of the unit cell model and verification of the finite element implementation is discussed. A series of experiments were performed to validate the in-plane behavior of the model. The proposed model can be adopted by designers to better represent the nonlinear mechanical behavior of the fabric. It can also be used as a tool to design novel fabrics that are optimized for a particular application.

description: Stopover niche utilization of birds during migration has not gained much attention so far, since the majority of the studies focuses on breeding or wintering areas. However, stopover sites are crucial for migratory birds. They are often used by a multitude of species, which could lead to increased competition. In this work, we investigated niche use of 8 migratory and closely related Emberiza bunting species at a stopover site in Far East Russia, situated on the poorly studied East Asian flyway. We used bird ringing data to evaluate morphological similarity as well as niche overlap on the trophic, spatial, and temporal dimension. Bill morphology was used as a proxy for their trophic niche. We were able to prove that a majority of the species occupies well-defined stopover niches on at least one of the dimensions. Niche breadth and niche overlap differ between spring and autumn season with higher overlap found during spring. Morphological differences are mostly related to overall size and wing pointedness. The temporal dimension is most important for segregation among the studied species. Furthermore, all species seem to exhibit a rather strict and consistent phenological pattern. Their occurrence at the study site is highly correlated with their geographic origin and the length of their migration route. We assume that buntings are able to use available resources opportunistically during stopover, while trying to follow a precise schedule in order to avoid competition and to ensure individual fitness.

description: The first results of single jet observables in Pb+Pb collisions at sqrt(s_NN)=2.76 TeV measured with the ATLAS detector at the LHC are presented. Full jets are reconstructed with the anti-kt algorithm with R= 0.2 and 0.4, using an event-by-event subtraction procedure to correct for the effects of the underlying event including elliptic flow. The geometrically-scaled ratio of jet yields in central and peripheral events,Rcp, indicates a clear suppression of jets with ET >100 GeV. The transverse and longitudinal distributions of jet fragments is also presented. We find little no substantial change to the fragmentation properties and no significant change in the level of suppression when moving to the larger jet definition.

description: This study aimed at examining physiological responses (i.e., oxygen uptake [VO2] and heart rate [HR]) to a semi-contact 3 x 3-min format, amateur boxing combat simulation in elite level male boxers. Eleven boxers aged 21.4 +/- 2.1 years (body height 173.4 +/- 3.7, body mass 74.9 +/- 8.6 kg, body fat 12.1 +/- 1.9, training experience 5.7 +/- 1.3 years) volunteered to participate in this study. They performed a maximal graded aerobic test on a motor-driven treadmill to determine maximum oxygen uptake (VO2max), oxygen uptake (VO2AT) and heart rate (HRAT) at the anaerobic threshold, and maximal heart rate (HRmax). Additionally, VO2 and peak HR (HRpeak) were recorded following each boxing round. Results showed no significant differences between VO2max values derived from the treadmill running test and VO2 outcomes of the simulated boxing contest (p > 0.05, d = 0.02 to 0.39). However, HRmax and HRpeak recorded from the treadmill running test and the simulated amateur boxing contest, respectively, displayed significant differences regardless of the boxing round (p < 0.01, d = 1.60 to 3.00). In terms of VO2 outcomes during the simulated contest, no significant between-round differences were observed (p = 0.19, d = 0.17 to 0.73). Irrespective of the boxing round, the recorded VO2 was >90% of the VO2max. Likewise, HRpeak observed across the three boxing rounds were >= 90% of the HRmax. In summary, the simulated 3 x 3-min amateur boxing contest is highly demanding from a physiological standpoint. Thus, coaches are advised to systematically monitor internal training load for instance through rating of perceived exertion to optimize training-related adaptations and to prevent boxers from overreaching and/or overtraining.

description: A Tannakian category is an abelian tensor category equipped with a fiber functor and additional structures which ensure that it is equivalent to the category of representations of some affine groupoid scheme acting on the spectrum of a field extension. If we are working over an arbitrary commutative ring rather than a field, the categories of representations cease to be abelian. We provide a list of sufficient conditions which ensure that an additive tensor category is equivalent to the category of representations of an affine groupoid scheme acting on an affine scheme, or, more generally, to the category of representations of a Hopf algebroid in a symmetric monoidal category. In order to do this we develop a "formal theory of Tannaka duality" inspired by Ross Street's "formal theory of monads." We apply our results to certain categories of filtered modules which are used to study p-adic Galois representations.

description: $\bar{K}$-nucleon interactions are investigated in the framework of coupled-channels dynamics based on the next-to-leading order chiral SU(3) meson-baryon effective Lagrangian. A recent determination of the 1s shift and width of kaonic hydrogen enables us to set accurate constraints on the coupled-channels meson-baryon amplitudes in the strangeness $S=-1$ sector. Theoretical uncertainties in the subthreshold extrapolation of the coupled-channels amplitudes are discussed. Using this framework, we give predictions for $K^-$-neutron interactions and for the spectrum of the $Λ(1405)$ resonance. A simplified, effective three-channel model using leading order chiral SU(3) meson-baryon interactions is also constructed for convenient application in $\bar{K}$-nuclear few-body calculations.

description: We study light-beam propagation in a nonlinear coupler with an asymmetric double-channel waveguide and derive various analytical forms of optical modes. The results show that the symmetry-preserving modes in a symmetric double-channel waveguide are deformed due to the asymmetry of the two-channel waveguide, yet such a coupler supports the symmetry-breaking modes. The dispersion relations reveal that the system with self-focusing nonlinear response supports the degenerate modes, while for self-defocusingmedium the degenerate modes do not exist. Furthermore, nonlinear manipulation is investigated by launching optical modes supported in double-channel waveguide into a nonlinear uniform medium.

description: Introduction: The availability of multiple PCR assays and extraction methods for SARS-CoV-2 viral ribonucleic acid cause a concern on their agreement. Validation tests have been conducted when new assays or extraction methods are introduced to understand their performance. This study evaluates the agreement of the results between different extraction methods and PCR assays. Methods: We searched the laboratory data in Sibu Hospital Clinical Research Centre Laboratory for any PCR validation results from 1 January to 31 May 2021 using two or more assays or extraction methods. A pooled gold standard was created by defining any samples detected positive using any extraction methods or assays. Wecalculatedtheaccuracyparameters. We compared the cyclic threshold (Ct) value for positivegenesinbothPCRassays. Results: The agreements for samples extracted manually versus automated method and run on Seegene was 0.869; on BioSewoom was 0.899. When extracted manually or using automated, the agreements for two different assays were 0.911 and 1.000, respectively. Cyclic threshold (Ct) using automated extraction was significantly lower in both assays (p<0.001). Compared to the pooled gold standard, both assays performed well using automated extraction, but BioSewoom extracted manually had lower sensitivity (86.67%; 95% CI: 69.28, 96.24) and negative predictive value (96.49%; 95% CI: 91.70, 98.56). Conclusion: The assays and extraction methods were generally in good agreement and accurate, albeit some differences. It is important to understand their performance to guide the interpretation and assist in patients management and pandemic.

description: A standard practise in palaeogenome analysis is the conversion of mapped short read data into pseudohaploid sequences, frequently by selecting a single high-quality nucleotide at random from the stack of mapped reads. This controls for biases due to differential sequencing coverage, but it does not control for differential rates and types of sequencing error, which are frequently large and variable in datasets obtained from ancient samples. These errors have the potential to distort phylogenetic and population clustering analyses, and to mislead tests of admixture using D statistics. We introduce Consensify, a method for generating pseudohaploid sequences, which controls for biases resulting from differential sequencing coverage while greatly reducing error rates. The error correction is derived directly from the data itself, without the requirement for additional genomic resources or simplifying assumptions such as contemporaneous sampling. For phylogenetic and population clustering analysis, we find that Consensify is less affected by artefacts than methods based on single read sampling. For D statistics, Consensify is more resistant to false positives and appears to be less affected by biases resulting from different laboratory protocols than other frequently used methods. Although Consensify is developed with palaeogenomic data in mind, it is applicable for any low to medium coverage short read datasets. We predict that Consensify will be a useful tool for future studies of palaeogenomes.

description: Introduction: Patients with oral potentially malignant disorders (OPMD) require regular follow-up which was disrupted during the COVID-19 pandemic1. At least 50% of patients had their appointments cancelled or postponed. Teleconsultation has been demonstrated as a viable approach to follow-up oral lesions2. To facilitate continued care, we evaluated the use of the MeMoSA®, as an application for teleconsultation. Objectives: 1. To evaluate knowledge and perception of OPMD patients towards teleconsultation. 2. To evaluate usability and acceptance of teleconsultation for follow-up of OPMD patients. Methodology: OPMD patients on long-term follow-up in University Malaya were invited to participate. Survey 1 was used to assess patients' knowledge and perception of teleconsultation. Patients who consented used MeMoSA® to capture and upload images of their oral lesion. Answers to clinical questions and the images were reviewed by specialists on MeMoSA® before a video teleconsultation through WhatsApp. Survey 2 was administered post-teleconsultation to assess usability and acceptance. Patients were examined face-to-face within three months from teleconsultation. Data were analysed using RStudio Statistical Software. Results: Forty-seven patients answered Survey 1. The majority were aged above 50 years (85.1%) and had oral lichen planus (87.2%). Thirty-two of 47 (72.3%) participated in teleconsultation. Knowledge on teleconsultation was low (34%), but more than 77% had positive perception. Seventy-percent of patients would like teleconsultation to be integrated within their care. Ninety-percent of patients agreed that teleconsultation increases convenience and accessibility to care. The majority (80%) found MeMoSA® to be simple and easy to use. In 83.3% of patients, specialists found that images and information provided during teleconsultation were sufficient for clinical decision making, similar to face-to-face examination. A 100% of patients would like to continue having teleconsultation as an option. Conclusion: Teleconsultation is well-accepted by patients and could facilitate OPMD patient follow-up particularly during the COVID-19 pandemic.

description: The Spanish colonisation of the Philippines in 1565 opened up trade between China, Latin America and Europe via the Pacific crossing, changing the history of global trade forever. The traditional understanding of the early colonial period in the Philippines suggests that colonial control spread rapidly and peacefully across the islands, ushering in dramatic changes to the social, political and economic environment of the archipelago. This dissertation argues by contrast that the extent of Spanish control has been overstated – partially as a by-product of an over-reliance on religious and secular chronicles that sought to magnify the role and interests of the colonial state. Through extensive archival work examining different sites of colonial authority and power, I demonstrate that Philippine communities contested and limited the nature of colonisation in their archipelago. In making this argument, I challenge prevalent assumptions of indigenous passivity in the face of imperial expansion. By demonstrating the agency of Southeast Asians, particular actors come to the fore in each of the chapters: Chinese labourers, indigenous elites, fugitives and apostates, unpacified mountain communities, native priestesses and Moro slave raiders. The culture and social organisation of these Southeast Asian communities impacted on the nature of Spanish imperialism and the capacity for the Spanish to retain and extend their control. Throughout the seventeenth century, the Spanish presence within the archipelago was always tenuous. A number of communities remained outside of Spanish control for the duration of the century, while still others oscillated between integration and rebellion, by turns participating in and resisting the consolidation of empire. These communities continued to maintain their local and regional economies and customs. Thus, by the end of the seventeenth century, imperial control remained fragmented, partial and incomplete. The dissertation contributes not only to the historiography of the Philippines – which remains under-explored – but also to the historiographies of Colonial Latin America, Southeast Asia and early modern empires. Conceptualising the Philippines as a frontier space helps to overturn the foundations of the myth of a completed conquest. This dissertation thus raises questions about the inevitability of empire by arguing that indigenous communities were active respondents to Spanish colonisation attempts and that indigenous traditions and culture in this region were both resilient and enduring in the face of colonial oppression.

Investigating diet and dietary change using the stable isotopes of carbon and nitrogen in mummified tissues from Puruchuco-Huaquerones, Peru

description: Bibliography: p. 282-389
description: Puruchuco-Huaquerones is one of the largest cemeteries ever discovered in South America. Between 2200 and 2400 individuals have been recovered, most dating to the Late Horizon (A.D. 1476-1532). Five tissues (bone, hair, nail, skin and muscle) were sampled from 72 partially mummified individuals and analyzed for the stable isotopes of carbon and nitrogen. Soft tissues record short term diet, in the months antemortem; whereas bone records long term diet, 10-25 years antemortem. Isotope data from all tissues indicated the diet included primarily maize and lower trophic level animals (e.g., guinea pig, camelid) but also included some C3 resources. Although the site was close to the sea, isotope data, for most individuals, were not consistent with the consumption of marine foods. The isotopic composition of soft tissues demonstrated that C3 resources (e.g., tubers) were cyclically incorporated into the diet. Tubers are a wet season crop harvested during the coastal winter. As such, their consumption was likely limited to the winter months. This cyclical variation enabled the determination of season of death by comparing the carbon isotope data from sequential samples of hair and nail. Approximately 60% to 70% of individuals died during the winter. There were dietary differences between males and females; males had greater access to maize, perhaps as chicha beer, and animal protein relative to females. Isotope data from all tissues indicated that individuals buried in rope encased bundles, assumed to be high status, and individuals interred without weaving tools, consumed a diet enriched in ¹³C and ¹⁵N relative to the rest of the population. Marine foods are enriched in ¹³C and ¹⁵N relative to maize and lower trophic level animals; consequently, isotope data for high status individuals are consistent with preferential access to marine foods. When isotope data from soft tissues were compared against isotope data from bone, the average values were similar. As such, although short term diet varied in the months before death, foods consumed in the short term were isotopically similar to the foods consumed in the last 10-25 years of life. This indicates that the individuals interred at Puruchuco-Huaquerones were native to the coast.

Our goal is to reach a simple and qualitative description of the these complicated phenomena. We develop an analytical and numerical technique able to study ram pressure, Kelvin-Helmholtz instability, Rayleigh-Taylor and tidal forces acting on the star formation processes in molecular clouds. We consider it together with synthetic colour magnitude diagrams techniques. We developed a method to investigate the connections existing between gas consumption processes and star formation processes in the context of the two extended-body interaction with special attention to the dwarf galaxies dynamical regime.

description: The innovative dual-purpose chicken approach aims at contributing to the transition towards sustainable poultry production by avoiding the culling of male chickens. To successfully integrate sustainability aspects into innovation, goal congruency among actors and clearly communicating the added value within the actor network and to consumers is needed. The challenge of identifying common sustainability goals calls for decision support tools. The objectives of our research were to investigate whether the tool could assist in improving communication and marketing with respect to sustainability and optimizing the value chain organization. Three actor groups participated in the tool application, in which quantitative and qualitative data were collected. The results showed that there were manifold sustainability goals within the innovation network, but only some goals overlapped, and the perception of their implementation also diverged. While easily marketable goals such as ‘animal welfare’ were perceived as being largely implemented, economic goals were prioritized less often, and the implementation was perceived as being rather low. By visualizing congruencies and differences in the goals, the tool helped identify fields of action, such as improved information flows and prompted thinking processes. We conclude that the tool is useful for managing complex decision processes with several actors involved.

description: We have entered an era of massive data sets in astronomy. In particular, the number of supernova (SN) discoveries and classifications has substantially increased over the years from few tens to thousands per year. It is no longer the case that observations of a few prototypical events encapsulate most spectroscopic information about SNe, motivating the development of modern tools to collect, archive, organize and distribute spectra in general, and SN spectra in particular. For this reason we have developed the Weizmann Interactive Supernova data REPository - WISeREP - an SQL-based database (DB) with an interactive web-based graphical interface. The system serves as an archive of high quality SN spectra, including both historical (legacy) data as well as data that is accumulated by ongoing modern programs. The archive provides information about objects, their spectra, and related meta-data. Utilizing interactive plots, we provide a graphical interface to visualize data, perform line identification of the major relevant species, determine object redshifts, classify SNe and measure expansion velocities. Guest users may view and download spectra or other data that have been placed in the public domain. Registered users may also view and download data that are proprietary to specific programs with which they are associated. The DB currently holds >8000 spectra, of which >5000 are public; the latter include published spectra from the Palomar Transient Factory, all of the SUSPECT archive, the Caltech-Core-Collapse Program, the CfA SN spectra archive and published spectra from the UC Berkeley SNDB repository. It offers an efficient and convenient way to archive data and share it with colleagues, and we expect that data stored in this way will be easy to access, increasing its visibility, usefulness and scientific impact.

description: The Tibetan Plateau, the world's largest orogenic plateau, hosts thousands of lakes that play prominent roles as water resources, environmental archives, and sources of natural hazards such as glacier lake outburst floods. Previous studies have reported that the size of lakes on the Tibetan Plateau has changed rapidly in recent years, possibly because of atmospheric warming. Tracking these changes systematically with remote sensing data is challenging given the different spectral signatures of water, the potential for confusing lakes with glaciers, and difficulties in classifying frozen or partly frozen lakes. Object-based image analysis (OBIA) offers new opportunities for automated classification in this context, and we have explored this method for mapping lakes from LANDSAT images and Shuttle Radar Topography Mission (SRTM) elevation data. We tested our algorithm for most of the Tibetan Plateau, where lakes in tectonic depressions or blocked by glaciers and sediments have different surface colours and seasonal ice cover in images obtained in 1995 and 2015. We combined a modified normalised difference water index (MNDWI) with OBIA and local topographic slope data in order to classify lakes with an area > 10 km(2). Our method derived 323 water bodies, with a total area of 31,258 km(2), or 2.6% of the study area (in 2015). The same number of lakes had covered only 24,892 km(2) in 1995; lake area has increased by -26% in the past two decades. The classification had estimated producer's and user's accuracies of 0.98, with a Cohen's kappa and F-score of 0.98, and may thus be a useful approximation for quantifying regional hydrological budgets. We have shown that our method is flexible and transferable to detecting lakes in diverse physical settings on several continents with similar success rates.

description: The paper shows how a generalization of the elasticity theory to four dimensions and to space-time allows for a consistent description of the homogeneous and isotropic universe, including the accelerated expansion. The analogy is manifested by the inclusion in the traditional Lagrangian of general relativity of an additional term accounting for the strain induced in the manifold (i.e. in space-time) by the curvature, be it induced by the presence of a texture defect or by a matter/energy distribution. The additional term is sufficient to account for various observed features of the universe and to give a simple interpretation for the so called dark energy. Then, we show how the same approach can be adopted back in three dimensions to obtain the equilibrium configuration of a given solid subject to strain induced by defects or applied forces. Finally, it is shown how concepts coming from the familiar elasticity theory can inspire new approaches to cosmology and in return how methods appropriated to General Relativity can be applied back to classical problems of elastic deformations in three dimensions.

An economic evaluation of oil fiscal regimes

description: This paper presents a utility maximization model to evaluate the impact of alternative oil fiscal regimes, which define the type of "contract" between a host government and a foreign oil company (FOC). Specifically, in order to determine the optimal fiscal regime, we use four fiscal systems (i.e. bonus bidding, income tax, royalties and production sharing agreement with cost recovery) to analyze how the utility of each of the parties change when each of these regimes is applied. It is found that the most efficient fiscal regime will depend not only on the endogenous variables defined in the model (i.e. reserve size, price, tax rate, investment, probability of finding oil, and firm's effort), but also of the risk aversion level exhibited by the host government and the FOC.
Diet and nutrition in white-faced capuchins (cebus capucinus): effects of group, sex and reproductive state

description: Bibliography: p. 90-98
description: White-faced capuchins ( Cebus capucinus) are considered behaviourally and ecologically flexible and their dietary patterns are no exception. My study is the first to examine the nutritional composition of wild capuchin foods and compare ingestion, nutrient and energy intake rates among: 1) groups with different habitats 2) males and females; and 3) females in different reproductive states. Females inhabiting early successional forest displayed higher rates of insect, fat and protein ingestion than females in semi-evergreen habitat. This suggests that monkeys in younger forests may compensate for lower quality habitat by consuming more food. Lactating females had higher ingestion rates than other females and tended toward higher nutrient intake rates, perhaps due to costs of milk production and infant care. However, overall energy intake rates were not significantly different by group, sex or reproductive state, suggesting that energy may be a limiting factor for capuchins and remain constant across individuals, even as their diets vary.

Mathematics and biophysics of cortical microtubules in plants
Creators: name: Allard, Jun
Publisher: name: University of British Columbia
Year: 2010

description: Microtubules confined to the two-dimensional cortex of elongating plant cells must form a parallel yet dispersed array transverse to the elongation axis for proper cell wall expansion. Collisions between microtubules, which migrate via hybrid treadmilling, can result in plus-end entrainment (zippering) or catastrophe. Here, I present (1) a cell-scale computational model of cortical microtubule organization and (2) a molecular-scale model for microtubule-cortex anchoring and collision-based interactions between microtubules. The first model treats interactions phenomenologically while the second addresses interactions by considering energetic competition between crosslinker binding, microtubule bending and microtubule polymerization. From the cell-scale model, we find that plus-end entrainment leads to self-organization of microtubules into parallel arrays, while collision-induced catastrophe does not. Catastrophe-inducing boundaries can tune the dominant orientation. Changes in dynamic-instability parameters, such as in mor1-1 mutants in Arabidopsis thaliana, can impede self-organization, in agreement with experiment. Increased entrainment, as seen in clasp-1 mutants, conserves self-organization, but delays its onset. Modulating the ability of cell edges to induce catastrophe, as the CLASP protein may do, can tune the dominant direction and regulate organization. The molecular-scale model predicts a higher probability of entrainment at lower collision angles and at longer unanchored lengths of plus-ends. The models lead to several testable predictions, including the effects of reduced microtubule severing in katanin mutants and variable membrane-anchor densities in different plants, including Arabidopsis cells and Tobacco cells.

description: Ba$_{0,5}$Sr$_{0,5}$Co$_{0,8}$Fe$_{0,2}$O$_{3-δ}$ (BSCF) zeichnet sich durch seine exzellente und energieeffiziente Bereitstellung von reinem Sauerstoff aus. Jedoch treten Instabilitäten in den elektrischen Eigenschaften und im Sauerstofftransport auf, welche auf strukturelle Änderungen im Kristallgitter zurückzuführen sind. Durch Dotierung mit Y, Ti und Nb soll die Stabilität des Gitters gewährleistet werden. Inwiefern die elektro¬chemischen Eigenschaften beeinflusst werden ist die zentrale Fragestellung dieser Arbeit.

description: We analyze general structure of N-fold supersymmetry which provides a systematic framework to construct weakly quasi-solvable quantum mechanical systems. Main ingredients of our analysis are dimensional analysis and introduction of an equivalent class of linear differential operators associated with N-fold supersymmetry for each N. To illustrate how they work, we construct the most general form of N-fold supersymmetric systems for N=2, 3, and 4.

description: We construct the screening currents of the quantum superalgebra $U_q(\hat{sl}(N|1))$ for an arbitrary level $k \neq -N+1$. We show that these screening currents commute with the superalgebra modulo total difference. We propose bosonizations of the vertex operators by using the screening currents. We check that these vertex operators are the intertwiners among the Fock-Wakimoto representation and the typical representation for rank $N \leq 4$.

description: 7. Hedychridium mediocrum Linsenmaier, 1987
Hedychridium mediocrum Linsenmaier 1987: 142. Holotype ♂; Switzerland: Wallis (NMLS) (examined) (Hedychridium ardens group).
Remarks. The species was reported from Sweden by Cederberg (2000: 177, 2005: 290), Soon (2004: 45) and Sörensson (2008e). According to Sörensson (2008e), the species was found on the island of Öland (Tävelsrum) in 1977. However, later it became obvious that the specimens were incorrectly determined and represented H. caputaureum. The species was removed from the Swedish fauna in Dyntaxa (2013).
