Consisting of two cross-sectional studies, the present study investigated whether psychological flexibility mediates the relations between self-concealment and negative psychological outcomes. Study 1 examined whether psychological flexibility mediates the relations between self-concealment and emotional distress in stressful interpersonal situations. In addition to replicating results of Study...
Despite data resilient methods against error that are applied on video data in transmitter side, occurringerror along video data transferring for communication channels is inevitable. Error concealment is a useful method for improving the quality of damaged videos in receiver side. In this paper, a fast and hybrid boundary matching algorithm is presented for more accurate estimating of damaged ...
Introduction: Previous studies have indicated a relationship between MPTP pore and AV nodal rate-dependent properties. The aim of present study was to determine acute direct effects of cyclosporine on extracellular field potential of isolated rabbit AV node during experimental atrial fibrillation. Methods: In one group of male New Zealand rabbits (1.5-2.5 kg) cumulative concentrations of cyc...

Introduction: Despite extensive studies about effects of Crataegus monogyna on cardiovascular diseases yet, a few study has been undertaken antiarrhythmic property of this plant. Aims of the present study were: 1) To determine the protective role of methanolic extract of C.monogyna on the rate-dependent model and the concealed conduction . 2) To explore the role of Na+-K+ A TPase in the protect...
In this paper, we propose content-adaptive refined error concealment schemes for video transmission over packet lossy networks. The proposed spatial and temporal error concealment algorithms improve the reconstructed video quality at the common loss rates encountered on the networks. To reduce the computational complexity, the proposed schemes make use of the existing information of Intra predi...
The plant community within which flower evolution takes place has largely been ignored. We develop two models for the evolution of nectar concealment when flowers are visited by legitimate pollinators and flower parasites. When there is a single plant species, no level of nectar concealment is evolutionarily stable: any population can be invaded by mutants exhibiting a higher level of nectar co...
Small herbivores face risks of predation while foraging and are often forced to trade off food quality for safety. Life history, behaviour, and habitat of predator and prey can influence these trade-offs. We compared how two sympatric rabbits (pygmy rabbit, Brachylagus idahoensis; mountain cottontail, Sylvilagus nuttallii) that differ in size, use of burrows, and habitat specialization in the s...
Digital TV signals being transmitted over errorprone channels often suffer from lost macro blocks or slices. In literature, a wide range of approaches for error concealment is described exploiting spatial and/or temporal references. In 2008, we introduced a new paradigm for error concealment utilizing several representations of a particular TV signal which are available in multi-broadcast-recep...
