Radiation and advection frost are common in Jordan as well as other neighboring countries as they face several frost waves each year during the late months of winter. Recently, many frost episodes hit the valley and damaged the crops that were compensated by millions of dollars by the Jordanian Government. This manuscript addresses and characterizes frost, and assesses the role of global warming in impacting frost in terms of its frequency, severity, and total number of frost days per year. A comprehensive statistical approach was used. The paper indicates that frost waves will continue to hit in the near future regardless of the fact that Earth is moving towards warmer conditions. Agricultural and financial authorities should be urged to minimize frost damage by considering installing wind fans in Jordan valley as an active method in addition to implementing good farm practices (as a passive methods where deemed necessary).

One of the most important properties of M-matrices is element-wise non-negative of its inverse. In this paper, we consider element-wise perturbations of tridiagonal M-matrices and obtain bounds on the perturbations so that the non-negative inverse persists. The largest interval is given by which the diagonal entries of the inverse of tridiagonal M-matrices can be perturbed without losing the property of total nonnegativity. A numerical example is given to illustrate our findings.

Recently,a single letter change has taken the world by storm.A group of experts have developed a consensus to upgrade the term non-alcoholic fatty liver disease(NAFLD)to metabolic associated fatty liver disease(MAFLD),suggesting that MAFLD would more accurately reflect not only the disease pathogenesis but would also help in patient stratification for management with ***,the difference of opinion exists,which has made the NAFLD vs MAFLD debate the current talk of the *** review will focus on the plausibility and implications of redefining NAFLD as MAFLD.
