Then the resolvent can be uniquely defined for in the upper half-plane, but not in the lower half-plane, due to the obstruction for all test functions (note that the function lies in when is in the lower half-plane). For related reasons, the translation operators have a problem with ...
Humanity is getting good at this: at the current stage, our skills at looking for signs of life in the Solar System and beyond are almost optimal. There is a timid consensus that we will find signs of life outside Earth in about a generation. Not finding them would be a harrowing ...
Polunium-208 has a half life of 2.898 years. If the original sample was 10 grams, how much will remain after 1 year? We can set this up as a differential equation, with as the amount, as time, and as a constant. This is a separable differential equation, and can be solved to ...
In this sample, the Cronbach’s alpha estimate for the CES-D-10 was 0.76. Life satisfaction was measured using 13 questions to enquire about the older adults’ satisfaction with their family relationships, financial situation, and living conditions. Responses are assessed on a five-point Likert-...
From these results, it is necessary to note that the extended trial equation method and generalized Kudryashov method provide strong mathematical tools for finding the analytical solutions of the new Hamiltonian amplitude equation and Fokas-Lenells equation and both methods are highly influential in ter...
The main finding is that virtually all respondents (97.8%) acknowledged that Jinchuan’s air is heavily polluted. In particular, more than 70% perceived high intensity and hazardousness of air pollution despite the fact that public information on air pollution and its health impacts is not freely...
The Drake Equation is used to estimate the number of communicating civilizations in the cosmos, or more simply put, the odds of finding intelligent life in the universe.
