Managing radio network congestion in UTRA-FDD

Electronics Letters, 2002
The presence of different service classes in the context of 3G mobile communication systems opens up new possibilities to exploit the spectrum in an efficient way. In the search of such a high efficiency, radio network congestion may arise and it is mandatory to include suitable algorithms to deal with these situations.

Decline of Visual Function and Risk of Legal Blindness With Age in RPGR‐Associated Retinal Degeneration: A Multicenter Study

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background This retrospective multicenter longitudinal analysis analysed the loss trajectory of best recorded visual acuity (BRVA) and Goldmann visual field (GVF) in RPGR‐associated retinal degeneration (RPGR‐RD). Methods Patients with genetically confirmed RPGR‐RD were classified into rod‐cone (RC), cone/cone‐rod (CR) and female‐carrier ...

Distal interphalangeal joint capsule enthesopathy of the middle phalanx and articular cartilage loss

Equine Veterinary Journal, EarlyView.
Abstract Background Significant distal interphalangeal joint (DIPJ) pathology, particularly affecting soft tissue and articular cartilage, is often not identifiable on radiographs but can be accompanied by joint capsule enthesopathy on the middle phalanx (P2), which can be readily identified.

Long-term temporal changes in the occurrence of a high forest fire danger in Finland [PDF]

Natural Hazards and Earth System Sciences, 2012
Climate variation and change influence several ecosystem components including forest fires. To examine long-term temporal variations of forest fire danger, a fire danger day (FDD) model was developed. Using mean temperature and total precipitation of the

Economic policy uncertainty and international corporate leasing

Journal of Financial Research, EarlyView.
Abstract We examine the effect of economic policy uncertainty (EPU) on the corporate lease decision using an international sample of 19 countries. The use of operating leases increases when EPU is heightened. The documented leasing increase is more pronounced for financially constrained firms, firms facing greater operating volatility, or those that ...

Optimal Portfolio Choice With Cross‐Impact Propagators

Mathematical Finance, EarlyView.
ABSTRACT We consider a class of optimal portfolio choice problems in continuous time where the agent's transactions create both transient cross‐impact driven by a matrix‐valued Volterra propagator, as well as temporary price impact. We formulate this problem as the maximization of a revenue‐risk functional, where the agent also exploits available ...
