A perception of International Tourists toward Tourism Products in and around Yangon

This research studied the perceptions of international tourists towards tourism products in and around Yangon. Field research consisted of a sample size of 385 respondents at 5% tolerable level of error by applying a simple random sampling method. Both descriptive and inferential statistics were used for data analysis. The findings show that overall perception by respondents is neutral to all tourism products of the study. Respondents are indifference in the perception of attractions, travel agents and restaurants when they are distinguished by age levels, gender, education level and purpose of travel. Similarly, there is no difference in perception of international tourists in the following aspects: accommodation when distinguished by age levels, gender; transportation when distinguished by nationality, age levels, gender and purpose of travel; entertainment when distinguished by nationality, gender, education levels and purpose of travel; gifts and souvenirs when distinguished by gender, education level and purpose of travel. Surprisingly, the findings suggest that difference in gender has no effect on perception of international tourists towards any products of study

Pure Asymmetric Quantum MDS Codes from CSS Construction: A Complete Characterization

Using the Calderbank-Shor-Steane (CSS) construction, pure $q$-ary asymmetric quantum error-correcting codes attaining the quantum Singleton bound are constructed. Such codes are called pure CSS asymmetric quantum maximum distance separable (AQMDS) codes. Assuming the validity of the classical MDS Conjecture, pure CSS AQMDS codes of all possible parameters are accounted for.Comment: Change in authors' list. Accepted for publication in Int.

The Connection between the Intracluster Light and its Host Halo: Formation Time and Contribution from Different Channels

We extend the analysis presented in \cite{contini2023a} to higher redshifts, up to $z=2$, by focusing on the relation between the intracluster light (ICL) fraction and the halo mass, its dependence with redshift, role played by the halo concentration and formation time, in a large sample of simulated galaxy groups/clusters with $13\lesssim \log M_{halo} \lesssim 15$. Moreover, a key focus is to isolate the relative contributions provided by the main channels for the ICL formation to the total amount. The ICL fraction at higher redshift is weakly dependent on halo mass, and comparable with that at the present time, in agreement with recent observations. Stellar stripping, mergers and pre-processing are the major responsible channels of the ICL formation, with stellar stripping that accounts for $\sim 90\%$ of the total ICL, regardless of halo mass and redshift. Pre-processing is an important process for clusters to accrete already formed ICL. The diffuse component forms very early, $z\sim 0.6$, and its formation depends on both concentration and formation time of the halo, with more concentrated and earlier formed haloes that assemble their ICL earlier than later formed ones. The efficiency of this process is independent of halo mass, but increases with decreasing redshift, which implies that stellar stripping becomes more important with time as the concentration increases. This highlights the link between the ICL and the dynamical state of a halo: groups/clusters that have a higher fraction of diffuse light are more concentrated, relaxed and in an advanced stage of growth.Comment: Corrected for several bugs and typos.
