Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)

Measurement of the CP-violating phase \phi s in Bs->J/\psi\pi+\pi- decays
No full textMeasurement of the mixing-induced CP-violating phase phi_s in Bs decays is of prime importance in probing new physics. Here 7421 +/- 105 signal events from the dominantly CP-odd final state J/\psi pi+ pi- are selected in 1/fb of pp collision data collected at sqrt{s} = 7 TeV with the LHCb detector. A time-dependent fit to the data yields a value of phi_s=-0.019^{+0.173+0.004}_{-0.174-0.003} rad, consistent with the Standard Model expectation. No evidence of direct CP violation is found
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
Experimental investigation into the effect of substrate clamping on the piezoelectric behaviour of thick-film PZT elements
No full textThis paper details an experimental investigation of the clamping effect associated with thick-film piezoelectric elements printed on a substrate. The clamping effect reduces the measured piezoelectric coefficient, d33, of the film. This reduction is due to the influence of the d31 component in the film when a deformation of the structure occurs, by either the direct or indirect piezoelectric effect. Theoretical analysis shows a reduction in the measured d33 of 62%, i.e. a standard bulk lead zirconate titanate (PZT)-5H sample with a manufacturer specified d33 of 593pC/N would fall to 227.8pC/N. To confirm this effect, the d33 coefficients of five thin bulk PZT-5H samples of 220µm thickness were measured before and after their attachment to a metallized 96% alumina substrate. The experimental results show a reduction in d33 of 74% from 529pC/N to 139pC/N. The theoretical analysis was then applied to existing University of Southampton thick-film devices. It is estimated that the measured d33 value of 131pC/N of the thick-film devices is the equivalent of an unconstrained d33 of 345pC/N
Simulating soil N₂O emissions in arable Eastern Scotland
No full textNitrous oxide (N₂O) is a powerful greenhouse gas and a major contributor to ozone
layer depletion. The application of nitrogenous fertilisers to agricultural soils is a major
source of N₂O on a global scale. Arable soils receive significant rates of synthetic
nitrogen (N) and thus have a considerable N₂O footprint. The reduction of the N₂O
footprint of agricultural systems is a key target for those countries that seek to reduce
their contribution to climate change and achieve a more sustainable agriculture. These
twin targets are part of Scotland's agro-environmental policy. Because soil N₂O emissions
vary significantly both temporally and spatially, measuring N₂O emissions across
wide agricultural areas is impractical. However, the quantification of the N₂O footprint
of important agricultural regions is very valuable to scientists, farmers and policymakers
alike. In this context, agro-ecosystem biogeochemistry models are scientific tools,
which are developed using in-depth knowledge on the underlying processes, and are
used to quantify N₂O emissions across spatial and temporal scales. In Scotland, arable
agriculture is concentrated at the Eastern part of the country where wheat, barley and
oilseed rape are the most widely cultivated crops. The main aim of this study was
to quantify the amount of N₂O that is emitted from arable soils due to the cultivation
of these three crops in Eastern Scotland by using the Landscape-DNDC model.
Landscape-DNDC is a mechanistic biogeochemistry model that describes the flows of
energy, water and nutrients in agricultural ecosystems. As part of the study, the parametric
sensitivities of key model outputs have been quantified using well-established
sensitivity analysis methods, which were tailored in order to consider the particularities
of N cycling in arable soils. Driven by the fact that the existence of spatiotemporal
uncertainties around field-measured soil N₂O data complicates the evaluation of model
performance, a novel model evaluation algorithm has been developed and was used to
assess the model's predictive accuracy. By combining the knowledge of the model's
parametric sensitivity with the
abilities of the evaluation algorithm, nine key parameters of Landscape-DNDC were
calibrated to UK edaphoclimatic conditions (using the Metropolis-Hastings Bayesian
calibration algorithm). Model calibration led to improved prediction of field-measured
soil N₂O emissions at a set of sites. The model was then coupled to geographically
explicit data on climate, soil N₂O and crop management and used to simulate N₂O
emissions from the arable soils of Eastern Scotland. The results show that, on average,
0.59 % of the applied fertiliser N (kg N ha-1) was lost to the atmosphere as N₂O.
This factor is much lower than the generic N2O emission factor (EF) of 1% and closer
to the UK cropland-specific N₂O EF (i.e. 0.79%). The predicted annual N₂O was
the combined result of different drivers (i.e. fertiliser rate, soil and climate variables)
but the geographic distribution of the estimated N₂O EFs revealed some hotspots
of high N₂O EF (larger than 1%). Interestingly, these hotspots were caused by the
cultivation of winter oilseed rape on soils with high bulk density and clay content. The
comparison of the simulated yields per hectare with respective measured data and of the
simulated nitrate (NO-3 ) leaching and crop N uptake factors with respective literature-based
values showed that the prediction of soil N₂O was not made at the expense
of realistic prediction of other important aspects of agro-ecosystem biogeochemistry.
Also, the study found that the simulated N₂O is almost twice as sensitive to soil input
uncertainty as the simulated NO-3 is, while, crop N uptake is rather insensitive to this
source of uncertainty. Finally, the study shows that the uncertainty around the nine
calibrated model parameters affects the prediction of NO-3 leaching strongly but its
role in regards to the simulation of N₂O emissions is small

DUS Topp–Leone-G Family of Distributions: Baseline Extension, Properties, Estimation, Simulation and Useful Applications
No full textThis study introduces the DUS Topp–Leone family of distributions, a novel extension of the Topp–Leone distribution enhanced by the DUS transformer. We derive the cumulative distribution function (CDF) and probability density function (PDF), demonstrating the distribution’s flexibility in modeling various lifetime phenomena. The DUS-TL exponential distribution was studied as a sub-model, with analytical and graphical evidence revealing that it exhibits a unique unimodal shape, along with fat-tail characteristics, making it suitable for time-to-event data analysis. We evaluate parameter estimation methods, revealing that non-Bayesian approaches, particularly Maximum Likelihood and Least Squares, outperform Bayesian techniques in terms of bias and root mean square error. Additionally, the distribution effectively models datasets with varying skewness and kurtosis values, as illustrated by its application to total factor productivity data across African countries and the mortality rate of people who injected drugs. Overall, the DUS Topp–Leone family represents a significant advancement in statistical modeling, offering robust tools for researchers in diverse fields
