In the pre-COVID era, had rapidly growing worldwide. supported by all newest developments in information communications technology (ICT). This fact raises concerns about its potential negative impact on tourist destinations. Sustainable management of destinations is thus becoming necessary stakeholders ...

In this paper, we study online algorithms for the Canadian Traveller Problem defined by Papadimitriou and Yannakakis in 1991. This problem involves a traveller who knows entire road network advance, wishes to travel as quickly possible from source vertex s destination t, but discovers that some roads are blocked (e.g., snow) once reaching them. Achieving bounded competitive ratio is PSPACE-comp...

After a brief history of the insights gained from Kaon physics, the potential of Kaon decays for probing lepton number violation is discussed. Present tests of CTP and of Quantum Mechanics in the neutral Kaon sector are then reviewed and the potential of the Frascati Φ factory for doing incisive tests in this area is emphasized. The rest of this overview focuses on CP violating effects in the K...

and the plain, the traveller was warned to traverse it at speed, and to beware of loitering even a single night within its limits, at the peril of a deadly jungle fever. Referring specially to that length of the Terai which fringes the Darjeeling hills, I have 110 difficulty in understanding how it came by its bad name. The vegetation, which covers the hill-sides, runs uninterruptedly into the ...

In the last years, cases of chikungunya fever have been reported in international travellers returning from the Indian Ocean region. The cases have been linked to the re-emergence of chikungunya fever on Indian Ocean islands in 2006. We describe the first case of chikungunya fever in a French traveller returning from Male, an island of the Maldives islands, confirming the permanence of virus ci...
