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
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.

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. The product branching fractions of psi(3686) -> gamma chi(cJ), chi(cJ) -> 4K(S)(0 )are presented, and the branching fractions of chi(cJ) -> 4K(S)(0) decays are determined to be B-chi c0 -> 4KS0 = (5.76 +/- 0.34 +/- 0.38) x 10(-4), B-chi c1 -> 4KS0 = (0.35 +/- 0.09 +/- 0.03) x 10(-4) and B-chi c2 -> 4KS0( )= (1.14 +/- 0.15 +/- 0.08) x 10(-4), where the first uncertainties are statistical and the second are systematic, respectively

chi(cJ) polarizations at the Fermilab Tevatron
No full textWe propose the measurement of chi (cJ) polarizations at high energy hadron colliders to study heavy quarkonium production mechanism. We find that the color-singlet model in the k(t) factorization approach predicts very different behavior for chi (cJ) polarizations at the Fermilab Tevatron compared with the NRQCD predictions in the collinear parton model. In the color-singlet k(t) factorization approach, for both chi (c1) and chi (c2) productions, the helicity h = 0 states dominate over other helicity states at large p(T). These properties are very useful in distinguishing between the two production mechanisms which are related to the interesting issue of J psi and psi' polarizations, and may provide a crucial test for the k(t) factorization approach.

QCD radiative corrections to chi(cJ) production at hadron colliders
No full textTo clarify the outstanding problem in charmonium production that existing theories cannot explain the observed cross sections of chi(cJ)(J = 0, 1, 2) and ratio R-chi c = sigma(chi c2)/sigma(chi c1) approximate to 0.75(in contrast to the spin counting value 5/3) at the Tevatron, we study the complete next-to-leading order radiative corrections in nonrelativistic QCD, and find next-to-leading order contributions of P-3(J)vertical bar 1 vertical bar are more important than leading order at high p(T), and P-3(1)vertical bar 1 vertical bar decreases slower than P-3(2)vertical bar 1 vertical bar, implying a natural explanation for the R-chi c puzzle. By fitting R-chi c, the predicted cross sections of chi(cJ) are found to agree with data. The result indicates coloroctet contribution is crucially needed, thus providing a unique test for heavy quarkonium production mechanisms. Feed-down contributions of chi(cJ) to prompt J/psi production are estimated to be substantial, about 30%-40% at p(T) = 20 GeV. Production of chi(cJ)(J = 0, 1, 2) at the LHC is also predicted.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000291464100001&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Astronomy & AstrophysicsPhysics, Particles & FieldsSCI(E)71ARTICLE11null8

Study of the processes ?cJ ? ? ? ? ¯ + and ?0 ? ¯ 0
No full textAbstract: Using 448.1 × 106?(3686) decays collected with the BESIII detector at the BEPCII e+e? storage rings, the branching fractions and angular distributions of the decays ?cJ? ??? ¯ + and ?0? ¯ 0 (J = 0, 1, 2) are measured based on a partial-reconstruction technique. The decays ?c1? ?0? ¯ 0 and ?c2? ?0? ¯ 0 are observed for the first time with statistical significances of 7? and 15?, respectively. The results of this analysis are in good agreement with previous measurements and have significantly improved precision. [Figure not available: see fulltext.] © 2022, The Author(s)
