description: The turbulent destruction of a cloud subject to the passage of an adiabatic shock is studied. We find large discrepancies between the lifetime of the cloud and the analytical result of Hartquist et al. (1986). These differences appear to be due to the assumption in Hartquist et al. that mass-loss occurs largely as a result of lower pressure regions on the surface of the cloud away from the stagnation point, whereas in reality Kelvin-Helmholtz (KH) instabilities play a dominant role in the cloud destruction. We find that the true lifetime of the cloud (defined as when all of the material from the core of the cloud is well mixed with the intercloud material in the hydrodynamic cells) is about 6 times t_KHD, where t_KHD is the growth timescale for the most disruptive, long-wavelength, KH instabilities. These findings have wide implications for diffuse sources where there is transfer of material between hot and cool phases. The properties of the interaction as a function of Mach number and cloud density contrast are also studied. The interaction is milder at lower Mach numbers with the most marked differences occuring at low shock Mach numbers when the postshock gas is subsonic with respect to the cloud (i.e. M < 2.76). Material stripped off the cloud only forms a long "tail-like" feature if the density contrast of the cloud to the ambient medium, chi > 1e3.

description: Thermal annealing of Si/Si1-xSbx/Si amorphous thin film tri-layer samples (x=18 and 24 at%Sb) under 100 bar Ar pressure results in an interesting pattern formation. In pictures, taken by means of cross-sectional transmission electron microscopy (TEM), stripe-shaped contrast, with three maxima, parallel with the interfaces can be seen. Secondary neutral mass spectrometer (SNMS) measurements revealed that the regions with different contrasts correspond to Sb-rich and Sb-depleted regions. Furthermore, the Sb concentration peaks in the Sb-rich regions, especially at longer annealing times, are different: the peak developed at the Si/SiSb interface closer to the free surface decays faster than that of the inner one closer to the substrate. The pattern formation is interpreted by segregation-initiated spinodal-like decomposition, while the difference of the Sb concentration peaks is explained by the resultant Sb transport to and evaporation from the free surface. The possible role of formation of nanocrystalline grains, in the explanation of the fast transport under pressure as compared to vacuum is also discussed.

description: We present a theoretical analysis of x-ray-absorption near-edge structure at the Sr K edge in La_2-xSr_xCuO_4 and SrF_2 compounds based on the experimental results of Tan et al. [Phys. Rev. Lett. 64, 2715 (1990)]. Contrary to the suggestion put forward in this investigation which is based on the observation of a certain absorption structure, we obtain the best agreement with experimental data when the environment of the dopant Sr atom is kept fixed in its crystallographic arrangement.

description: We study a class of lattice field theories in two dimensions that includes gauge theories. We show that in these theories it is possible to implement a broader notion of local symmetry, based on semi-simple Hopf algebras. A character expansion is developed for the quasitopological field theories, and partition functions are calculated with this tool. Expected values of generalized Wilson loops are defined and studied with the character expansion.

description: A series of c-axis oriented electron-doped high-Tc superconducting La(2-x)CexCuO4 thin films, from heavily underdoped x=0.06 to heavily overdoped x=0.19, have been synthesized by dc magnetron sputtering technique on (100) SrTiO3 substrates. The influence of various fabrication conditions, such as the deposition temperature and the deposition rate, etc., on the quality of the thin films has been scrutinized. We find that the quality of the films is less sensitive to the deposition temperature in the overdoped region than that in the underdoped region. In the phase diagram of Tc(x), the superconducting dome indicates that the optimally doping level is at the point x=0.105 with the transition temperature Tc0 = 26.5 K. Further more, both the disappearance of the upturn in the $ρ_{xx}$(T) curve at low temperature under H=10 T and the positive differential Hall coefficient, $R_H'=d ρ_{xy}/dH$, are observed around x = 0.15, implying a possible rearrangement of Fermi surface at this doping level.

Our predictions reproduce very well the few data available at energies between 1.5 and 4.2 GeV, where our approach can be applied. Moreover, we found a good agreement also with the forward and backward angle data in the intermediate energy region.

description: The linear strong--property--fluctuation theory (SPFT) was developed in order to estimate the constitutive parameters of certain homogenized composite materials (HCMs) in the long--wavelength regime. The component materials of the HCM were generally orthorhombic $mm2$ piezoelectric materials, which were randomly distributed as oriented ellipsoidal particles. At the second--order level of approximation, wherein a two--point correlation function and its associated correlation length characterize the component material distributions, the SPFT estimates of the HCM constitutive parameters were expressed in terms of numerically--tractable two--dimensional integrals. Representative numerical calculations revealed that: (i) the lowest--order SPFT estimates are qualitatively similar to those provided by the corresponding Mori--Tanaka homogenization formalism, but differences between the two estimates become more pronounced as the component particles become more eccentric in shape; and (ii) the second--order SPFT estimate provides a significant correction to the lowest--order estimate, which reflects dissipative losses due to scattering.

description: The e.m. component of Extensive Air Showers, as a sampled at a given atmospheric depht, may be considered as the superposition of sub-showers initiated by photons and electrons (positrons) mainly coming from the decay of secondary mesons. A detailed simulation of showers in atmosphere as produced by gammas and electrons has been performed by means of standard high energy physics Monte Carlo codes. We developed a set of parametrisations of these sub-showers to be included in the full simulations of Extensive Air Showers with the aim to reduce the required computer power. Comparison with previous results found in the literature are shown.

Gill tissue respiration in two species of crabs, Hemigrapsus nudus and Hemigrapsus oregonensis
Creators: name: McCaughran, Donald Alistair
Publisher: name: University of British Columbia
Year: 2011

description: Oxygen consumption of gill tissue of Hemigrapsus nudus and H. oregonensis has been measured at four levels of experimental salinity (35%, 75%, 100%, and 125% sea water), three levels of experimental temperature (5°, 12,5° and 20°C) in all combinations for both winter and summer animals. Summer animals of both species were found to have higher weight-specific oxygen consumption than winter animals when measured at the average summer (20°C, 35% sea water) and winter (5°C, 75% sea water) field conditions. At other experimental conditions respiration rates of summer-adapted animals were found to be higher for the majority of conditions, but there were examples of equal seasonal rates and examples of winter rates exceeding those obtained from summer animals. Winter animals were found to be less temperature-dependent than summer animals. No laboratory compensation to temperature of biological significance could be found in either species. Hemigrapsus nudus demonstrated a higher weight-specific oxygen consumption than H. oregonensis. Both species showed with minor differences, similar responses to the various factors investigated. The weight-specific oxygen consumption data present indirect evidence which indicate that the gills of both species are involved in regulating blood ions. The indications are that regulation of ions by the gills is more pronounced in summer than in winter. The regression coefficient of weight-specific oxygen consumption as a function of whole body weight was found to have a value of -0.169. This value was similar for both species and not affected by experimental conditions. The differences in physiological response between species indicate that the less variable Hemigrapsus nudus may be a select population which has migrated into this area from the outer coast and that H. oregonensis may be indigenous to this locality.

description: Nonmagnetic cloak offers a feasible way to achieve invisibility at optical frequencies using materials with only electric responses. In this letter, we suggest an approximation of the ideal nonmagnetic cloak and quantitatively study its electromagnetic characteristics using a full-wave scattering theory. It is demonstrated that the forward scattering of the impedance matched cloak increases dramatically as the thickness of the cloak decreases. Nevertheless, it is still possible to effectively reduce the total scattering cross section with a very thin cloak whose impedance is not matched to the surrounding material at the outer boundary. Our analysis also provides the flexibility of reducing the scattering in an arbitrary direction.

Design and Evaluation of Serious Games for Higher Orders of Learning on the Topic of Programming
Creators: name: Keil, Leonard
Publisher: name: Zenodo
Year: 2025
Subjects: subject: Gamification
subject: Educational Technology/education
subject: Serious Games

description: This thesis aims to give a better look at the research and development of educational Serious Games (SGs) with the specific goal of facilitating higher-order learning as described in Bloom’s Revised Taxonomy. Programming is one of the potential subjects that could be taught with the use of such a SG and is the main example used to explore the topic in applied detail. A foundation is established for a solid discussion of the matter and a new classification metric based on the containment of learning materials and application of acquired skills is proposed. We use this new metric in conjunction with established methods to analyze a subset of existing literature to validate its usefulness and extract valuable insights and potential avenues for success from the related work. Existing game mechanics are examined on their suitability for use in educational SGs and specifically related to their position in Bloom’s Revised Taxonomy and the resulting order of learning. This process revealed multiple promising mechanics and design paradigms and some entirely new variations. We successfully applied these in the creation of a design for an innovative programming SG that is optimized for high-order learning. The first steps towards an implementation are taken via early technical work on a prototype in the Godot engine, where different technologies were compared. Finally we discuss some possible modern evaluation and analysis techniques that could be included and outline future efforts to be taken.

description: Expansion was invented at the end of the 1970s for calculating principal typings for $λ$-terms in type systems with intersection types. Expansion variables (E-variables) were invented at the end of the 1990s to simplify and help mechanise expansion. Recently, E-variables have been further simplified and generalised to also allow calculating type operators other than just intersection. There has been much work on denotational semantics for type systems with intersection types, but none whatsoever before now on type systems with E-variables. Building a semantics for E-variables turns out to be challenging. To simplify the problem, we consider only E-variables, and not the corresponding operation of expansion. We develop a realisability semantics where each use of an E-variable in a type corresponds to an independent degree at which evaluation occurs in the $λ$-term that is assigned the type. In the $λ$-term being evaluated, the only interaction possible between portions at different degrees is that higher degree portions can be passed around but never applied to lower degree portions. We apply this semantics to two intersection type systems. We show these systems are sound, that completeness does not hold for the first system, and completeness holds for the second system when only one E-variable is allowed (although it can be used many times and nested). As far as we know, this is the first study of a denotational semantics of intersection type systems with E-variables (using realisability or any other approach).

description: A series of electron-doped cuprate La(2-x)CexCuO4 thin films with different thicknesses have been fabricated and their annealing time are adjusted carefully to ensure the highest superconducting transition temperature. The transport measurements indicate that, with the increase of the film thickness (<100 nm), the residual resistivity increases and the Hall coefficient shifts in the negative direction. Further more, the X-ray diffraction data reveal that the c-axis lattice constant c0 increases with the decrease of film thickness. These abnormal phenomena can be attributed to the insufficient oxygen reduction in the thin films. Considering the lattice mismatching in the ab-plane between the SrTiO3 substrates and the films, the compressive stress from the substrates may be responsible for the more difficult reduction of the oxygen in the thin films.

Chiral Dynamics of the Polarizing Fracture Functions for Baryon Production

Publisher: name: arXiv
Year: 2008
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The concept of spin-directed momentum provides a useful and restrictive framework for describing dynamical mechanisms that can lead to single-spin observables. The value of this framework can be demonstrated by consideration of the polarizing fracture functions that characterize the production of polarized baryons in the target fragmentation region of semi-inclusive deep inelastic scattering from an unpolarized target. When Bjorken x is chosen large enough to indicate a hard scattering from a valence quark, the fracture function formalism dynamically selects a quark-diquark basis for baryon structure. Attention to sonstituent orbital angular momentum in the formation process and its role in contribution to the transverse momentum of the produced baryon illustrates important aspects of the generation of polarization observables.

description: This study aims to test the hypothesis of moderation of tax avoidance on CSR with LQ share prices, The sample used in this study is the financial statements of LQ-45 companies listed on the IDX for the 2018-2022 period. The independent variable in this study is CSR, tax and the dependent variable is stock price. The research method used is quantitative research. Based on the results of the study showed that tax avoidance carried out using the effective tax rate (ETR) of 7.086 > 2.002 and the significance value of 0.000 was lower at = 0.05. These results show a significant impact on the value of the company's shares. This supports H1 that tax avoidance has a significant effect on company value. Corporate social responsibility is carried out with an index calculation of 5.393 > 2.002 and a significance level of 0.000 and low = 0.05. These results show a significant impact on the value of the company's shares. This supports H2 that corporate social responsibility has a significant influence on corporate value. Profitability with return on equity (ROE) as an adjustment variable of 2.622 < 2.002, the significance level is 0.011, which is as low as = 0.05. These results well suggest that profitability can increase the impact of tax avoidance on a company's stock value. This supports H3 that profitability can moderate the impact of tax avoidance on the value of company shares. Profitability with return on equity (ROE) as an adjustment variable of -1.654.

description: It is shown that the well-known blue-shift of the fundamental absorption edge in as-deposited compositionally modulated amorphous Si/Ge and As6Se94/Se80Te20 multilayers (with periods of 4-8 nm) is further enhanced due to the thermal or laser-induced intermixing of adjacent layers. The laser-induced intermixing process, as supported by experiments and model calculations, can be attributed to both the local heating and photo-effects in As6Se94/Se80Te20 multilayers, while only the thermal effects were observed for Si/Ge multilayers. Structural transformations, based on this enhanced interdiffusion, provides good capability for spatially patterning optoelectronic devices and digital information recording.

description: We present a result of age estimation for star clusters in M33. We obtain color-magnitude diagrams (CMDs) of resolved stars in 242 star clusters from the HST/WFPC2 images. We estimate ages of 100 star clusters among these, by fitting the Padova theoretical isochrones to the observational CMDs. Age distribution of the star clusters shows a dominant peak at log(t) ~ 7.8. Majority of star clusters are younger than log(t) = 9.0, while ten star clusters are older than log(t) ~ 9.0. There are few clusters younger than log(t) = 7 in this study, which is in contrast with the results based on the integrated photometry of star clusters in the previous studies. Radial distribution of the cluster ages shows that young to intermediate-age clusters are found from the center to the outer region, while old clusters are distributed farther from M33 center. We discuss briefly the implication of the results with regard to the formation of M33 cluster system.

It is determined that for effective management of stakeholders of agricultural projects it is necessary to take into account the mentality of stakeholders of such projects. The article presents a model of the mental space of stakeholders of agro-industrial complex projects, which visualizes the general and different mentalities of each of the stakeholders of the project. It is recommended to apply a mathematical model of anti-risk management of stakeholders in agro-industrial projects, to increase the efficiency of stakeholder management, and reduce the overall risk of the project. The author proposes to build alternative versions of the network schedule of the project so that on the critical path the contractors were appointed those stakeholders in whose mental space is more common, and calculating their risks and the risk of the whole project, choose a version of the network schedule, the risk of a critical path which will be minimal.

description: We study the production of a single top quark through the processes e +γ → νt overlineb, e +e - → W ∗γ ∗ → t overlineb + eν, and e +e - → W ∗W → t overlineb + eν within the minimal Standard Model. Numerical estimates of the signal cross-sections at LEP II energies are compared with pair production below threshold, e +e - → t overlinet∗ → tW ∗overlineb → t overlineb + eν . We show that if m top > {s}/{2}, the WW ∗and W ∗γ ∗ channels are dominant, but these processes give an interesting event rate only if the expected luminosity could be ameliorated relative to present estimates.

description: The article considers the physiological activity of plant growth stimulants based on phytohormones. Plant growth regulators by their nature are analogs of phytohormones or modifiers of their action. Therefore, the physiological effect of growth stimulants is determined by changes in the balance of biologically active substances in the plant organism. The use of developmental stimulants containing compounds of auxin, gibberellin, cytokinin and brassine nature is substantiated.Exogenous treatment of compounds with analogues of phytohormones, their antagonists or regulators of activity, intensively effect on the metabolic processes and lead to changes in growth processes, allows improving of the seed productivity of plants

description: We consider the quantum mechanical hamiltonian of two, space indexed, hermitean matrices. By introducing matrix valued polar coordinates, we obtain the form of the laplacian acting on invariant states. For potentials depending only on the eigenvalues of the radial matrix, we establish that the radially invariant sector is equivalent to a system of non interacting 2+1 dimensional fermions, and obtain its density description. For a larger number of matrices, the presence of a repulsive radial inter-eigenvalue potential is identified.

Coincidences in Gravitational Wave Experiments

Publisher: name: INFN Open Access Repository
Year: 1995

description: The experimental information about gravitational waves is practically nonexistent. The only available experimental information comes from the binary pulsar PSR 1913+16 by J.H. Taylor and J.M. Weisberg(1), which shows indirect evidence for gravitational waves emitted by a continuous source and their quadrupole nature. We believe it is likely that the direct observation of gravitational waves will show phenomena at present unpredictable, as most of the times have happened in science for new discoveries.In designing the experiment we must certainly take into consideration the present theories of gravity , but we must be careful not rely on them too much. We must try to keep our mind open. Our search for gravitational waves will be based on experimental data obtained by applying the technique of coincidences among two or more detectors and by the statistical treatment of the data. We believe that this is one of the most delicate problems.In the following we shall discuss an experimental method to estimate the probabilities, already used by Joe Weber and by the gravitational waves hunters who had operating detectors. The outcome of this method we call experimental probability. We shall indicate the care needed when applying to the raw data filtering procedures for detecting small signals embedded into noise and finally we shall discuss the importance that the probability be estimated only on 'a priori' bases.
Oxidation and reduction of the C-11 position of corticosterone and 11-dehydrocorticosterone by mouse liver fractions in vitro
Creators: name: Lewis, Elizabeth Cairine
Publisher: name: University of British Columbia

description: Corticosterone and 20α dihydrocorticosterone have been found in the liver and blood of mice injected intravenously with C-11-dehydrocorticosterone. Within a few minutes after injection the latter is no longer detectable in the blood and liver, (1). The enzyme responsible for the reduction of the C-11 keto group has been isolated in the microsomal fraction of mouse liver homogenate. This fraction was precipitated by ultracentrifugation at 100,000 x G of the supernatant after centrifugation at 6,000 x G. NADPH₂ was established as the coenzyme required although limited activity could be demonstrated with NAD₂. The reaction can be reversed by use of NADP. Certain kinetic properties of the reaction have been investigated. The reaction velocity is proportional to enzyme concentration and linear with time over the period studied. For the reduction reaction with 11-dehydrocorticosterone as substrate Km = 1.8 x 10⁻⁵ and Vmax = 1.6 x 10⁻⁴ μmoles/ml/min. For the dehydrogenation reaction with corticosterone as substrate Km = 1.7 x 10⁻⁴ and Vmax = 2.7 x 10⁻³ μmoles/ml/min.

description: The most significant impact on the formation of winter productivity rapeseed had sowing dates, and a hybrid reaction to this indicator was observed. Thus, on average over the years of research, the maximum yield was achieved by early-maturing hybrid Exotic for the first sowing period with the application of the maximum fertilizer N240P120K240 4.10 t / ha. The lowest level of yield, on average over the years of research, was obtained by the middle-late hybrid Exagon for the first sowing period in the control variant without fertilizer application 0.77 t / ha. The amount of fertilizer applied also significantly affected the yield of plants, which is confirmed by the results of analysis of variance. Thus, the influence of fertilizer on the formation of the yield of hybrid Exotic was 84%, hybrid Excel 90% and Exagon 85%. It is established that the increase in the rate of fertilizer affected the change formation of qualitative indicators of seeds. Thus, the value of the acid number decreased with increasing norm, the best values of the acid number were in the hybrid Exagon for the first sowing period 1.38-1.10 mg KOH / g. The sowing period and the fertilizer variant influenced the change in the value of erucic acid content in winter rape seeds, while the increase in the fertilizer rate led to an increase in its content in the seeds. The accumulation and content of glucosinolates did not depend on the time of sowing, and fertilizer had a significant effect on this indicator the content of glucosinolates increased with increasing amount of fertilizers. The protein and oil content were influenced by the studied factors the maximum value of protein content in hybrids Exotic and Excel was observed during the second sowing period on August 21 and increased with increasing fertilizer from 19.07 to 22.57% and from 19.57 to 22.65%. Plants of winter rapeseed hybrid Exagon formed the highest protein values during the third sowing period on September 5 from 19.33 to 22.35%. The maximum value of oil content (total yield) in all hybrids was obtained in the variant with the introduction of N240P120K240: in the hybrid Exotic 1.85 t / ha for the first sowing period, in the hybrid Excel 1.76 t / ha for the third sowing period and in hybrid Exagon 1.71 t/ha for the second sowing period.

description: Let G be a finitely presented group. Scott and Swarup have constructed a canonical splitting of G which encloses all almost invariant sets over virtually polycyclic subgroups of a given length. We give an alternative construction of this regular neighbourhood, by showing that it is the tree of cylinders of a JSJ splitting.

description: Microstructure changes during annealing of nano-crystalline silver and amorphous silicon multilayers (Ag/a-Si) have been studied by X-ray diffraction and transmission electron microscopy. The dc-magnetron sputtered Ag/a-Si multilayers remained stable even after annealing at 523K for 10h, and microstructural changes occurred only above 600K. The degradation of Ag/a-Si multilayers can be described by the increase of size of Ag grains, formation of grooves and pinholes at Ag grain boundaries and by the diffusion of silicon atoms through the silver grain boundaries and along the Ag/a-Si interfaces. This results in thinning of a-Si layers, and in formation of Ag granulates after longer annealing times.

description: The use of orthogonal signaling schemes such as time-, frequency-, or code-division multiplexing (T-, F-, CDM) in multi-user systems allows for power-efficient simple receivers. It is shown in this paper that by using orthogonal signaling on frequency selective fading channels, the cooperative Nash bargaining (NB)-based precoding games for multi-user systems, which aim at maximizing the information rates of all users, are simplified to the corresponding cooperative resource allocation games. The latter provides additional practically desired simplifications to transmitter design and significantly reduces the overhead during user cooperation. The complexity of the corresponding precoding/resource allocation games, however, depends on the constraints imposed on the users. If only spectral mask constraints are present, the corresponding cooperative NB problem can be formulated as a convex optimization problem and solved efficiently in a distributed manner using dual decomposition based algorithm. However, the NB problem is non-convex if total power constraints are also imposed on the users. In this case, the complexity associate with finding the NB solution is unacceptably high. Therefore, the multi-user systems are categorized into bandwidth- and power-dominant based on a bottleneck resource, and different manners of cooperation are developed for each type of systems for the case of two-users. Such classification guarantees that the solution obtained in each case is Pareto-optimal and actually can be identical to the optimal solution, while the complexity is significantly reduced. Simulation results demonstrate the efficiency of the proposed cooperative precoding/resource allocation strategies and the reduced complexity of the proposed algorithms.

The KLOE Drift Chamber
Creators: name: A. Calcaterra
Publisher: name: INFN Open Access Repository
Year: 1996

description: The KLOE drift chamber is a cylinder of ~2m radius and ~3.3m long, providing an adequate path for KL decays. The tracking volume is surrounded by a 15X0 em calorimeter and a superconducting coil providing a 0.6T field. Spherical end walls hold the tension of ~50000 wires, with good trasparency, Š0.1X0, to photons from p0 decays. Alternating stereo wires only, with constant radial displacement at the center, provide a uniform filling with approximately square cells. A He-iC4H10 gas mixture and Al field wires are used to minimize multiple scattering. The chamber point resolution in r, f is significantly better than 200mm resulting in a KL�p+p- vertex accuracy of sx,y(z)Š0.5(1-2)mm. The K0 mass resolution is sM~1MeV/c2.

description: The aluminium 1s x-ray-absorptionspectra of a series of garnets, pyrope (Mg3Al2Si3O12), almandine (Fe3Al2Si3O12), spessartine (Mn3Al2Si3O12) and grossular (Ca3Al2Si3O12), are compared to full multiple-scattering calculations using cluster models. An overall good agreement between experiment and calculation, extended also to the edge region, is obtained in the energy range up to 60 eV above the threshold, provided clusters containing at least 40 atoms are used. The analysis of these garnet XAS spectra provides clear evidence on the effect of atoms located far away from the first-coordination shell around the photoabsorber. As a local probe, XANES spectroscopy at the edge of low Z elements appears to be a perfect tool to investigate the role played by atoms located in higher-coordination shells.
