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
Behavioral implications of shortlisting procedures
No full textWe consider two-stage “shortlisting procedures” in which the menu of alternatives is first pruned by some process or criterion and then a binary relation is maximized. Given a particular first-stage process, our main result supplies a necessary and sufficient condition for choice data to be consistent with a procedure in the designated class. This result applies to any class of procedures with a certain lattice structure, including the cases of “consideration filters,” “satisficing with salience effects,” and “rational shortlist methods.” The theory avoids background assumptions made for mathematical convenience; in this and other respects following Richter’s classical analysis of preference-maximizing choice in the absence of shortlisting
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.

Observation of chi(cJ) -> 4K(S)(0)
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
The biomechanics of foot and ankle problems after stroke and the effects of orthotics on such problems
No full textStroke is the leading cause of adult disability and -50% of people with stroke suffer foot deformities which influence walking. The aim of this study was to investigate foot and ankle biomechanics, posture, multi-segment kinematicsand plantar pressure in people with stroke and explore the possible causes and functional consequences of any abnormalities.A cross-sectional survey of the static foot posture in 72 people with stroke showed that one-third had abnormal and asymmetrical foot posture with almost equal numbers having pronated and supinated affected foot associated with limited walking ability.Stance phase foot and ankle biomechanics were quantified using a multisegment foot model on the affected side of twenty stroke and fifteen healthy age-matched subjects. The role of neuromuscular impairments in biomechanical abnormalities was characterised by concurrently measuring the electromyography and spasticity of major posterior and anterior lower leg muscles and the dynamometric measures of plantarflexor stiffness, plantarflexor and dorsiflexor strength and ankle proprioception.The following abnormalities in people with stroke were found: Reduced range of motion across most segments and planesA more pronated footA less supinated foot during propulsionDeficit in the foot rocker functionDisruption in the timing of joint motionChange in the coupling mechanismsGreater variabilityThe changes in pronation and supination were associated with limited walkingability and soleus spasticity and plantarflexor stiffness.The work also investigated the effects of lateral wedges orthoses on the eight lower leg muscles to understand the interactions between foot and ankle biomechanics and neuromuscular function. In eight healthy subjects, there wasa trend for peak muscle length, excursion and lengthening velocity to increase when wearing lateral wedges orthoses. The observed changes strongly support a follow-on study in a stroke population to explore the effects of lateral wedgeorthoses on muscle length and lengthening characteristic
