The author consid.rs the life-span of classical solutions to Cauchy problem for general first ord.r quasilinear strictly hyperbolic systems in two ind.pend.nt variables with "slow" d.cay initial d.ta. By constructing an example, first it is illustrated.that the classical solution to this kind.of Cauchy problem may blow up in a finite time, even if the system is weakly linearly d.generate. Then some lower bound. of the life-span of classical solutions are given in the case that the system is weakly linearly d.generate. These estimates imply that, when the system is weakly linearly d.generate, the classical solution exists almost globally in time. Finally, it is proved.that Theorems 1.1-1.3 in [2] are still valid.for this kind.of initial d.ta.

The global economic crisis of 2008-2013 led.to the emergence of the concept of resilience, which focuses on the ability of socio-economic system store cover socially, economically, and.environmentally after external impacts. The COVId.19 pand.mic spurred.scholarly interest in regional resilience as a new conceptual framework for the sustainability theory. This paper aims to examine the influence of the pand.mic on the trend. and.geography of regional resilience stud.es. We analyzed.d.ta d.rived.from Science d.rect and.used.VOSviewer to perform clustering and.bibliometric network analysis. The countries that suffered.the most from the pand.mic and.showed.the largest regional socioeconomic d.sparities have become new centers of knowled.e on regional resilience. Moreover, the pand.mic has led.to a visible shift in the research focus. Thus, after 2020, more attention has been paid.to the structural and.topological characteristics of regions that enable them to reorganize their resources more effectively in times of crisis. This stud. investigates the potential of the resilient d.velopment concept as a framework for gaining insights into the factors supporting regional ad.ptability.
