BACKGROUND Plain packaging (PP) with larger graphic health warnings (GHWs) was implemented in Australia in late 2012. This study examined effects of these packaging changes on short-term changes in quitting-related cognitions and behaviours. METHODS We used a series of cohorts of Australian adult cigarette smokers originally sourced from a nationally representative cross-sectional tracking su...

The algorithm of wavelet decomposition and reconstruction are applied in the audio error concealment method in this paper. When there is lost frame of the audio signal, the correct frames which lie before and after the lost frame are wavelet decomposed firstly. Then the two sets of the wavelet coefficients obtained from the wavelet decomposition are utilized to get the wavelet coefficients for ...

The present investigation empirically examined if the negative association between self-concealment and subjective well-being is spurious because it results from the associations of both variables with their common causes neuroticism and extraversion. We concluded from applying structural equation modeling to the data obtained from two independent student samples that neuroticism, but not extra...

People with concealable stigmatized identities often conceal to avoid facing prejudice and discrimination. Yet, this strategy carries risk; concealment may engender social costs. Across five studies in which participants (total n = 1992) were recruited from an online pool (Prolific) institutional undergraduate pool, we found that people who conceal, relative disclose, viewed as less moral socia...

The possibility of masking an accelerated two-qubit system by using a minimum number qubits is discussed. It shown that the information may be masked in either entangled local states or product non-local separable states. We examine each partition these satisfies conditions. Due to presence partition, one consider it type quantum data hiding scheme. local/non-local encoded state robust against ...

We present a novel error-concealment method for MPEG-2 video decoders. Imperfect transmission of block-based compressed images may result in the loss of blocks, degrading the quality of the received video signal. Since an I-picture is used as a reference picture for forward and backward predictions of neighbouring pictures, transmission errors in an I-picture are propagated both spatially in th...
