The vanishing author in computer-generated works: a critical analysis of recent Australian case law
Full text linkAbstract
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

Observation of psi(3686) -> e(+)e(-)chi(cJ) and chi(cJ) -> e(+)e(-)J/psi
No full textKolcu, Onur Buğra (Arel Author)Using 4.479 x 10(8) psi(3686) events collected with the BESIII detector, we search for the decays psi(3686) -> e(+)e(-)chi(cJ) and chi(cJ) -> e(+)e(-)J/psi, where J = 0, 1, 2. The decays psi(3686) -> e(+)e(-)chi(cJ) and chi(cJ) -> e(+)e(-)J/psi are observed for the first time. The measured branching fractions are B(psi(3686) -> e(+)e(-)chi(cJ)) = (11.7 +/- 2.5 +/- 1.0) x 10(-4), (8.6 +/- 0.3 +/- 0.6) x 10(-4), (6.9 +/- 0.5 +/- 0.6) x 10(-4) for J = 0, 1, 2, and B(chi(cJ) -> e(+)e(-)J/psi) = (1.51 +/- 0.30 +/- 0.13)x10(-4), (3.73 +/- 0.09 +/- 0.25)x10(-3), (2.48 +/- 0.08 +/- 0.16)x10(-3) for J = 0, 1, 2, respectively. The ratios of the branching fractions B(psi(3686) -> e(+)e(-)chi(cJ))/B(psi(3686) -> gamma chi(cJ)) and B(chi(cJ) -> e(+)e(-)J/psi)/B(chi(cJ) -> gamma J/psi) are also reported. Also, the alpha values of helicity angular distributions of the e(+)e(-) pair are determined for psi(3686) -> e(+)e(-)chi(c1,2) and chi(c1,2) -> e(+)e(-)J/psi

Asymptotic Stability of a Plane CJ Detonation Wave
No full text. We study the asymptotic stability of a plane CJ detonation wave under the assumption of small resolved heat release (SRHR). We prove that the solution exists globally and that the solution converges uniformly to a shifted CJ detonation wave as t!+ 1 for initial data which are small perturbations of the CJ detonation wave. The weighted energy method is used to overcome the difficulty arising from the sonic property at the end of the reaction. The SRHR model allows us to treat the non-monotone spike in the profile of the CJ detonation wave by the characteristic energy estimate. Key words. CJ detonation, shock wave, traveling wave, sonic point, asymptotic behavior, weighted energy estimate, characteristic energy estimate.

Helicity amplitude analysis of χ cJ → ϕϕ
No full textAbstract Using (447.9 ± 2.3) million ψ(3686) events collected with the BESIII detector, the decays of χ cJ → ϕϕ (J = 0, 1, 2) have been studied via the decay ψ(3686) → γχ cJ . The branching fractions of the decays χ cJ → ϕϕ (J = 0, 1, 2) are determined to be (8.59 ± 0.27 ± 0.20) × 10 −4, (4.26 ± 0.13 ± 0.15) × 10 −4, and (12.67 ± 0.28 ± 0.33) × 10 −4, respectively, which are the most precise measurements to date. From a helicity amplitude analysis of the process ψ(3686) → γχ cJ , χ cJ → ϕϕ, ϕ → K + K − , the polarization parameters of the χ cJ → ϕϕ decays are determined for the first time

No full textKolcu, Onur Buğra (Arel Author)By analyzing (448.1 +/- 2.9) x 10(6) psi(3686) events collected with the BESIII detector operating at the BEPCII collider, the decays of chi(c)(J) -> 4K(S)(0) (J = 0, 1, 2) are observed for the first time with statistical significances of 26.5 sigma, 5.9 sigma and 11.4 sigma, respectively.
