description: We study the estimators of various second-order weak lensing statistics such as the shear correlation functions xi_\pm and the aperture mass dispersion which can directly be constructed from weak lensing shear maps. We compare the efficiency with which these estimators can be used to constrain cosmological parameters. To this end we introduce the Karhunen-Loeve (KL) eigenmode analysis techniques for weak lensing surveys. These tools are shown to be very effective as a diagnostics for optimising survey strategies. The usefulness of these tools to study the effect of angular binning, the depth and width of the survey and noise contributions due to intrinsic ellipticities and number density of source galaxies on the estimation of cosmological parameters is demonstrated. Results from independent analysis of various parameters and joint estimations are compared. We also study how degeneracies among various cosmological and survey parameters affect the eigenmodes associated with these parameters.

This oblique transverse section of one pinnule also shows a lamina with palisade and spongy parenchyma but thin, more than 2 mm long, lateral extensions
 FIG. 8. — Silicified plants from the Permian of Sardinia: A, Pecop- teris sp., transverse section of one vegetative pinnule showing thick lamina with palisade and aerenchyma mesophyll.Note the hair (arrow) attached near the lower extremity (SAR15B1T02); B, Scolecopteris cf. elegans Zenker, oblique transverse section
 of one pinnule showing two synangia attached on the left side. Note the thick lamina similar to that of Pecopteris sp. (A) but long thin pinnule extension on the right (SAR40C01); C, Scolecopteris cf. parvifolia Millay, part of a longitudinal section of one pinnule passing through several synangia. Note the relatively thin lamina, synangia borne on a short vascularised pedicel and solid tips of sporangia (SAR56AT02); D, E, Scolecopteris cf. alta Millay; D, longitudinal section of a synangium showing the characteristic central column; E, transverse sections of synangia, the one above is through the basal part of the synangium, the other is through the distal region showing only four dehiscent sporangia (SAR01C2B02).

 of the lamina enclosing the synangia. These fertile pinnules correspond to those shown in paradermal section on Figure 7F and there is good evidence that they were borne by a rachis of the Stewartiopteris sp. 2 type (Fig. 7D). Despite strong similarities in sporangia and synangiate organization with Scolecopteris oliveri, the sizes of the pinnules (about 2 mm broad and 4-6 mm long), synangia and sporangia (less than 1 mm long) are smaller than those of S. oliveri, according to measurements given by Scott (1932). Moreover,the lateral pinnule extensions are much more pronounced than in S. oliveri; in fact, this Sardinian Scolecopteris rather resembles the organization and size of fertile pinnules of S. elegans Zenker, 1837 from the Lower Permian of Saxony (Barthel & Weiss 1997) or of S. minor Hoskins, 1926 from the Upper Pennsylvanian of Illinois which belong to the Scolecopteris minor group defined by Millay (1979; 1997).

 This may represent a second type of fertile parts with large pinnules (6 to 8 mm long and 2-2.5 mm wide), bearing two rows of up to 14 synangia, each consisting of 4 to 5 sporangia. The lamina is thin (200 µm) without a well-marked palisade or spongy tissue; sporangia (up to 0.9 mm long) are borne on a short vascularised pedicel(250 µm broad) and they are united around this pedicel in their proximal region. The sporangia tips are solid and bluntly pointed. This fertile structure is similar to that of S. parvifolia as defined by Millay (1979: pl. 10, fig. 66) from the Pennsylvanian American coal balls.

description: We define a new metric between natural numbers induced by the $\ell_\infty$ norm of their unique prime signatures. In this space, we look at the natural analog of the number line and study the arithmetic function $L_\infty(N)$, which tabulates the cumulative sum of distances between consecutive natural numbers up to $N$ in this new metric. Our main result is to identify the positive and finite limit of the sequence $L_\infty(N)/N$ as the expectation of a certain random variable. The main technical contribution is to show with elementary probability that for $K=1,2$ or $3$ and $ω_0,\ldots,ω_K\geq 2$ the following asymptotic density holds $$ \lim_{n\to\infty}\frac{\big|\big\{M\leq n:\; \|M-j\|_\infty

description: Differential equations are a powerful tool for evaluating Feynman integrals. Their solution is straightforward if a transformation to a canonical form is found. In this paper, we present an algorithm for finding such a transformation. This novel technique is based on a method due to Hoschele et al. and relies only on the knowledge of a single integral of uniform transcendental weight. As a corollary, the algorithm can also be used to test the uniform transcendentality of a given integral. We discuss the application to several cutting-edge examples, including non-planar four-loop HQET and non-planar two-loop five-point integrals. A Mathematica implementation of our algorithm is made available together with this paper.

description: The paper presents results of analysis of the organizational and production changes occurring in Polish agriculture with concern of regions, and the assessment of potential effects of its influence on the environment with the use of standard agri-environmental indicators. The trends of changes in grounds exploitation, sown areas, animals stocking density and population, mineral fertilization, and gross nitrogen balance for Poland have been determined. The analysis included middle-term perspective of years 2000-2012. The changes occurring in particular regions have been compared in the period of time between 2002- 2004 and 2010-2012. It has been established that existing natural factors, but mainly organizational and economic, significantly affect the changes occurring in agricultural sector leading to increasingly developing polarization, production specialization and concentration. The consequences of occurring processes are, regionally diversified, changes of standard agri-environmental indicators, implicating differential strength (pressure) of agricultural activity effects on the environment. The changes may have positive as well as negative consequences for the further working of the sector. There is an onward extensification of organization and agricultural production in the south-eastern provinces. The provinces’ levels of macro components consumption in mineral fertilizers, as well as animals stocking density in livestock buildings, are often twofold. There is an extensification of organization with simultaneous increase in its intensity in livestock production. The consequence of the organization extensification and its simultaneous increase is extension of environmental pressure on the areas of high concentration of livestock production (the Kuyavia-Pomerania, the Łódź and the Wielkopolska provinces) prominent in unbeneficial changes of agri-environmental indicators (e.g. nitrogen balance) resulting in i.a. deterioration in the quality of surface and ground water.
Study of coupling loss on bi-columnar BSCCO/Ag tapes by a.c. susceptibility measurements

description: Coupling losses were studied in composite tapes containing superconducting material in the form of two separate stacks of densely packed filaments embedded in a metallic matrix of Ag or Ag alloy. This kind of sample geometry is quite favorable for studying the coupling currents and in particular the role of superconducting bridges between filaments. By using a.c. susceptibility technique, the electromagnetic losses as function of a.c. magnetic field amplitude and frequency were measured at the temperature T = 77 K for two tapes with different matrix composition. The length of samples was varied by subsequent cutting in order to investigate its influence on the dynamics of magnetic flux penetration. The geometrical factor $χ_0$ which takes into account the demagnetizing effects was established from a.c. susceptibility data at low amplitudes. Losses vs frequency dependencies have been found to agree nicely with the theoretical model developed for round multifilamentary wires. Applying this model, the effective resistivity of the matrix was determined for each tape, by using only measured quantities. For the tape with pure silver matrix its value was found to be larger than what predicted by the theory for given metal resistivity and filamentary architecture. On the contrary, in the sample with a Ag/Mg alloy matrix, an effective resistivity much lower than expected was determined. We explain these discrepancies by taking into account the properties of the electrical contact of the interface between the superconducting filaments and the normal matrix. In the case of soft matrix of pure Ag, this is of poor quality, while the properties of alloy matrix seem to provoke an extensive creation of intergrowths which can be actually observed in this kind of samples.

title: Recycling oceanic crust: Isotopic and elemental constraints from a high pressure terrain
Creators: name: Dale, Christopher
Publisher: name: The Open University
Year: 2005

description: This study investigates the Re-Os and trace element budgets of gabbros, eclogites and metabasalts from subducted oceanic crust, at whole-rock and mineral scales. These data test the hypothesis that elevated 187OS/188OS ratios in some OIB evolved from the high Re/Os ratios of subducted oceanic crust recycled into their mantle source.

Re-Os data from metastable gabbros and corresponding eclogites from the Zermatt-Saas ophiolite (ZSO), which have undergone very high-pressure metamorphism (>2.0 GPa), yield a best-fit regression consistent with the crust formation age (164 Ma). ZSO eclogitic metabasalt data lie above this regression line, with a mean Re abundance of 440 ppt, substantially lower than current data for MORB glasses (~1000 ppt). This suggests that Re was lost from the basaltic crust (resulting in lower Re/Os ratios as found in a previous study), while low-strain gabbro bodies remain closed with respect to the Re-Os system during subduction. Re-Os data from pillow basalts of biotite, garnet and kyanite grades from the Sulitjelma ophiolite also indicate substantial Re loss, implying that this process may occur at lower P-T conditions during initial subduction.

Modelling the Os and Pb isotope evolution of a complete section of oceanic crust over 2 Ga implies that HIMU-type OIB can be produced by recycling >40% oceanic crust into the mantle source. Crucially, the effect of the gabbroic portion on the evolution of the whole crust is to considerably reduce 206Pb/204Pb ratios without altering the Os isotope evolution significantly. This permits long residence times for recycled crust in the mantle without generating Pb isotopic values higher than known OIB.

For the first time, mineral separates from gabbro and gabbroic eclogite have been analysed for Re and Os. Sulphide dominates the Os budget, while Re is mainly hosted in plagioclase for gabbro, and garnet for gabbroic eclogite.

Trace element measurements on the same mineral and bulk-rock samples are used to assess trace element fluxes during subduction. The most notable conclusion of this work is that U depletion occurs neither in the metabasalts nor metagabbros.

description: The aim of the study was an evaluation of spatial diversification of the production potential of agriculture in Poland. Land resources, labour and capital, as well as effectiveness of their use, have been analysed in 16 voivodeships in Poland. The study is based on data obtained from Central Statistical Office from 2012. Research shows that among the regions with the greatest resources of agricultural land there are the following voivodeships: Mazowieckie, Wielkopolskie and Lubelskie. The highest labour resources per 100 ha of the agricultural land were identified in the voivodeship of Malopolskie, Podkarpackie and Świetokrzyskie. Studies have shown that regions with a high level of development were accompanied by higher productivity of production factors in agriculture, while in the less developed voivodeships where there are structural problems in the sector concerned, land and labor productivity is usually lower. The lowest effective use of its potential production, especially with reference to labour factor, was therefore noted in such regions as Podkarpackie, Malopolskie, Świetokrzyskie and Lubelskie. Moreover, the existence of differences in the productive potential of the regions surveyed should be emphasised. The greatest variation was related to labour and land productivity, the smallest was noted in case of capital factor.

description: Present models describing the interaction of quantum Maxwell and gravitational fields predict a breakdown of Lorentz invariance and a non standard dispersion relation in the semiclassical approximation. Comparison with observational data however, does not support their predictions. In this work we introduce a different set of ab initio assumptions in the canonical approach, namely that the homogeneous Maxwell equations are valid in the semiclassical approximation, and find that the resulting field equations are Lorentz invariant in the semiclassical limit. We also include a phenomenological analysis of possible effects on the propagation of light, and their dependence on energy, in a cosmological context.

description: The aim of this study was to identify the currently functioning institutional support mechanisms for the development of the bio-economy in the Wielkopolska Region. In the initial stage of the study, conducted in late 2013 and 2014, secondary materials were used which had been published by the Central Statistical Office, reports by Association for Innovation and Entrepreneurship Centres, Ministry of Science and Higher Education and the information contained on the websites of the institutions. The study included selected administrative-political and economic institutions of Wielkopolska. It was determined whether and to what extent these mechanisms operate in support of activities aimed at bio-economy development. It was found that the biggest, targeted support in this area is offered by Nickel Technology Park, Poznan Science and Technology Park, Centre of Excellence “Food Biotechnology” and the Foundation for Academic Entrepreneurship. In the future, extensive support for bio-economy can be expected from Wielkopolska Centre for Advanced Technology which is in the start-up phase. In other institutions, such support is provided equally to other areas of business and scientific research or it is of no particular interest to the institution. The study does not exhaust the catalogue of the bio-economy support institutions in the region of Wielkopolska. At their present stage a slight targeting of support mechanisms was noted for the activities in the field of bio-economy. Continuation and specification of research is planned.

description: We observe the S-cluster star S62 on its Keplerian orbit around the supermassive black hole in the center of our galaxy, SgrA*. The orbital time period of S62 around SgrA* is 9.9 years. We derive its mass to be around 2 M_solar which is consistent with other members of the S-cluster. From the Lucy-Richardson deconvolved images, we determine a K-band magnitude of 16.1 mag. We observe almost two complete orbits of the star with two different and independent telescopes and three different instruments. The close distance of S62 to SgrA* at its periapse of around 2 mas results in a gravitational periapse shift of almost 10%/orbit.

title: The role of the self-advocacy support-worker in UK People First Groups: developing inclusive research
Creators: name: Chapman, Rohhss
Publisher: name: The Open University
Year: 2005

description: This thesis examines the role of self-advocacy support-workers in People First Groups within the UK. The study is undertaken through a process of inclusive research and involves a team of researchers from Carlisle People First. The research discovered that the self-advocacy support-worker role is ambiguous and contradictory. Current government policy and indications of the early formation of a social movement, suggest the role is likely to be enduring and therefore in need of being called to account. Support-workers and members, although in agreement with many of the central aims of self-advocacy, were often unaware of the multiple and conflicting requests made upon the support-workers by different individuals and organisations. The study sets out main areas of analysis and scrutiny of the role. The research provides empirical evidence for the possible development of the role based on the perspectives of both advocacy support workers and group members. The work on developing inclusive research highlights the benefits and problems of a qualitative team approach. The research challenges current assumptions that there are areas of the research cycle too difficult for people with learning difficulties to genuinely participate in. It is argued that methodological rigour need not be compromised and that person-led, team research can indeed improve aspects of validity and reliability.

description: Cordaixylon sp. (Fig. 9A)
 We illustrate a small, partly decorticated stem, about 6 mm in diameter. The cylinder of secondary xylem averages 4 mm and the pith 1.5 mm in diameter.The wood tracheids are small, ranging from 12-15 µm in diameter for the innermost ones to 20-30 µm in diameter at the periphery.The endarch maturation of the primary xylem conforms to the genus Cordaixylon Grand’Eury. On the surfaces studied the pith is solid and consists of a parenchyma of small cells (around 30 µm in diameter).One incomplete rachis, crescentshaped in cross section (P, Fig.9A), is closely associated with the stem; it certainly represents one petiole of this plant, as suggested by its vascular anatomy consisting of more than six bundles as it should be expected in the petiole of such a young cordaitean stem. Associated in the same chert block we found fragments of leaves with a thin lamina (Fig. 9F, see below).

In particular, we demonstrate a dynamic hysteresis of the Raman scattered optical field in response to changes of the drive laser field intensity and/or frequency. This effect may be described as a dynamic form of optical bistability resulting from the formation and decay of atomic coherence. We have applied this phenomenon to the realization of an all-optical switch.

description: Australian agriculture supplies many horticultural commodities to domestic and international markets; however, food composition data for many commodities are outdated or unavailable. We produced an up-to-date, nationally representative dataset of up to 148 nutrients and related components in 92 Australian-grown fruit (fresh n=39, dried n=6), vegetables (n=43) and nuts (n=4) by replacing outdated data (pre-2000), confirming concentrations of important nutrients and retaining relevant existing data. Primary samples (n = 902) were purchased during peak growing season in Sydney, Melbourne and Perth between June 2021 and May 2022. While new data reflect current growing practices, varieties, climate and analytical methods, few notable differences were found between old and new data where methods of analysis are comparable. The new data will be incorporated into the Australian Food Composition Database, allowing free online access to stakeholders. The approach used could serve as a model for cost-effective updates of national food composition databases worldwide.

description: A brief and biased overview of the phenomenon of confinement in QCD is presented in three parts: (1) the definition of confinement, (2) properties of confinement, (3) ideas of confinement. The second part chiefly consists of a brief review of recent lattice computations related to confinement while the third summarizes some of the current analytical approaches to understanding confinement. These include the Dyson-Schwinger formalism in Landau gauge, Hamiltonian QCD in Coulomb gauge, and the vortex picture of confinement.

description: We present a method for performing path integral molecular dynamics (PIMD) simulations for fermions and address its sign problem. PIMD simulations are widely used for studying many-body quantum systems at thermal equilibrium. However, they assume that the particles are distinguishable and neglect bosonic and fermionic exchange effects. Interacting fermions play a key role in many chemical and physical systems, such as electrons in quantum dots and ultracold trapped atoms. A direct sampling of the fermionic partition function is impossible using PIMD since its integrand is not positive definite. We show that PIMD simulations for fermions are feasible by employing our recently developed method for bosonic PIMD and reweighting the results to obtain fermionic expectation values. The approach is tested against path integral Monte Carlo (PIMC) simulations for up to 7 electrons in a two-dimensional quantum dot for a range of interaction strengths. However, like PIMC, the method suffers from the sign problem at low temperatures. We propose a simple approach for alleviating it by simulating an auxiliary system with a larger average sign and obtaining an upper bound to the energy of the original system using the Bogoliubov inequality. This allows fermions to be studied at temperatures lower than would otherwise have been feasible using PIMD, as demonstrated in the case of a three-electron quantum dot. Our results extend the boundaries of PIMD simulations of fermions and will hopefully stimulate the development of new approaches for tackling the sign problem.

description: We propose a new procedure named PASOA, for Bayesian experimental design, that performs sequential design optimization by simultaneously providing accurate estimates of successive posterior distributions for parameter inference. The sequential design process is carried out via a contrastive estimation principle, using stochastic optimization and Sequential Monte Carlo (SMC) samplers to maximise the Expected Information Gain (EIG). As larger information gains are obtained for larger distances between successive posterior distributions, this EIG objective may worsen classical SMC performance. To handle this issue, tempering is proposed to have both a large information gain and an accurate SMC sampling, that we show is crucial for performance. This novel combination of stochastic optimization and tempered SMC allows to jointly handle design optimization and parameter inference. We provide a proof that the obtained optimal design estimators benefit from some consistency property. Numerical experiments confirm the potential of the approach, which outperforms other recent existing procedures.

description: The work’s goal was to analyse the factors influencing decision of purchase of organic food by citizens of Krosno. Objects and research methods: the research conducted in 2010-2011 was executed with the use of a standardized inquiry questionnaire on a sample of 224 randomly picked citizens of Krosno. Results: Respondents declaring the purchase of organic food, most often upon its purchasing, pay attention to price and expiry date. When purchasing organic food the least important are shop assistant’s persuasion and the sort of package. Half of the buyers notice considerable difference between organic and conventional food. Almost all the respondents were at least content with the purchased organic food. Conclusions: 1. For citizens of Krosno, the availability of organic comestible food is limited by its high price and also by the fact that they are not on offer of stores in which respondents do the shopping most often. 2. The important factors influencing the increase in purchasing organic food are said to be the consumer’s greater awareness and advertisement.

Cordaites tenuistriatus

description: Cordaites tenuistriatus Grand’Eury, 1877   (Fig. 9C)
 In this leaf the lamina is thin and of variable thickness: 0.2 mm between veins to 0.4 mm at the level of veins due to the presence of triangular hypodermal sclerotic strands above and below the bundle sheath. This results in a typical superficial ribbing characteristic of the species C. tenuistriatus as illustrated by Renault (1879) from the Pennsylvanian of Grand-Croix. The interval between veins is less than 0.6 mm, i.e. about 17 veins per cm.

description: Here, we study the microlensing of radially pulsating stars. Discerning and characterizing the properties of distant, faint pulsating stars is achievable through high-cadence microlensing observations. Combining stellar variability period with microlensing gives the source distance, type, and radius and helps better determine the lens parameters. Considering periodically variations in their radius and surface temperature, their microlensing light curves are resulted from multiplication of the magnification factor with variable finite size effect by the intrinsic brightness curves of pulsing source. The variable finite source size due to pulsation can be significant for transit and single microlensing and while caustic-crossing features. This kind of deviation in the magnification factor is considerable when the ratio of the source radius to the projected lens-source distance is in the range of $ρ_{\star}/u \in[0.4,10]$ and its duration is short and in the same order of the time of crossing the source radius. Other deviations due to variable source intensity and its area make colored and periodic deviations which are asymmetric with respect to the signs of pulsation phase. The positive phases makes deviations with larger amplitude that negative phase. These deviations dominate in filters with short wave lengths (e.g., $B-$band). The position of magnification peaks in microlensing of variable stars varies and this displacement differs in different filters.

description: We study to what extent it is possible to generalise Berkovits' pure-spinor construction in d=10 to lower dimensions. Using a suitable definition of a ``pure'' spinor in d=4,6, we propose models analogous to the d=10 pure-spinor superstring in these dimensions. Similar models in d=2,3 are also briefly discussed.

In contrast, this leaf found associated with the previous one, shows a very thick (up to 1 mm) lamina and a superficial surface smooth. Sclerotic strands do not extend to the bundle sheath and intermediate strands occur between veins as illustrated by Renault (1879) for specimens from Grand-Croix and by Harms & Leisman (1961) from American Pennsylvanian coal balls. The interval between veins is about 0.7 mm, i.e. about 14 veins per cm.

Production of Tachyonic Neutrino in Matter

description: Recently, a new theory based on superluminal tunnelling has been proposed to explain the transition of highly energetic neutrinos propagating in matter to tachyonic states. In this work, we determine the possible mechanisms that lead neutrinos into a superluminal realm based on the assumption that ultrarelativistic neutrinos travelling in matter lose part of their energy with the emission of Bremsstrahlung radiation. The obtained photons, in turn, can create neutrino antineutrino pairs, one or both of which can be superluminal. We also prove that pair creation may occur with neutrino flavour oscillation provided that only one of them is a space-like particle. This suggests that mass oscillation and superluminal behaviour could be related phenomena. Finally, using the generalised Lorentz transformations, we formulate the Lagrangian of the kinematically allowed scattering processes. The structure of this Lagrangian is consistent with the formalism of the Standard Model. Based on this Lagrangian, at least one of the particles forming the pair must always be subluminal. The possibility that the pair creation process is mediated by a dark photon is also discussed.

description: As-grown superconducting MgB_2 thin films have been grown on SrTiO_3(001), MgO(001), and Al_2O_3(0001) substrates by a molecular beam epitaxy (MBE) method with novel co-evaporation conditions of low deposition rate in ultra-high vacuum. The structural and physical properties of the films were studied by RHEED, XRD, electrical resistivity measurements, and SQUID magnetometer. The RHEED patterns indicate three-dimensional growth for MgB_2. The highest T_c determined by resistivity measurement was about 36K in these samples. And a clear Meissner effect below T_c was observed using magnetic susceptibility measurement. We will discuss the influence of B buffer layer on the structural and physical properties.

Say hello to Algol's new companion candidates

description: Constant orbital period ephemerides of eclipsing binaries give the computed eclipse epochs (C). These ephemerides based on the old data can not accurately predict the observed future eclipse epochs (O). Predictability can be improved by removing linear or quadratic trends from the O-C data. Additional companions in an eclipsing binary system cause light-time travel effects that are observed as strictly periodic O-C changes. Recently, Hajdu et al. (2019) estimated that the probability for detecting the periods of two new companions from the O-C data is only 0.00005. We apply the new Discrete Chi-square Method (DCM) to 236 years of O-C data of the eclipsing binary Algol ($β$ Persei). We detect the tentative signals of at least five companion candidates having periods between 1.863 and 219.0 years. The weakest one of these five signals does not reveal a "new" companion candidate, because its $680.4 \pm 0.4$ days signal period differs only $1.4 σ$ from the well-known $679.85 \pm 0.04$ days orbital period of Algol~C. We detect these same signals also from the first 226.2 years of data, and they give an excellent prediction for the last 9.2 years of our data. The orbital planes of Algol~C and the new companion candidates are probably co-planar, because no changes have been observed in Algol's eclipses. The 2.867 days orbital period has been constant since it was determined by Goodricke (1783).
