      Mushanyu, Josiah; Nyabadza, Farai; Ngarakana-Gwasira, Ethel T.; Mafuta, Phillip (Springer, 2018-01-11)
      Drug abuse is an issue of considerable concern due to its association with numerous public health problems. Mathematical models developed to describe the spread of drug abuse have generally assumed that the dynamics of ...

    • A Note on the Discrete Spectrum of Gaussian Wells (I): The Ground State Energy in One Dimension 

      Muchatibaya, Gift; Fassari, S.; Rinaldi, F.; Mushanyu, Josiah (Hindawi Publishing Corporation, 2016-02-07)
      The ground state energy 𝐸 0(𝜆) of 𝐻 𝜆 = − 𝑑 2 /𝑑𝑥 2 − 𝜆 𝑒 −𝑥2 is computed for small values of 𝜆 by means of an approximation of an integral operator in momentum space. Such an approximation leads to a transcendental ...
