This investigation, in Bishop’s constructive mathematics in sense of well-known books [2], [3], [6] and Romano’s papers [9]-[15], is continuation of forthcoming Crvenkovic, Mitrovic and Romano’s paper [4], and the Romano’s paper [16]. Bishop’s constructive mathematics is developed on Constructive logic (or Intuitionistic logic ([19])) logic without the Law of Excluded Middle P ∨¬¬P . Let us not...

aim and background: schizophrenia is a chronic psychiatric disorder. the positive and negative symptoms are not only important in the prognosis of the disease but also affect the quality of life among the patients. therefore, the present survey aimed to determine the relationship between positive and negative symptoms and quality of life among schizophrenic patients in sina hospital in juneqan....

Using the basis of Hermite–Fourier functions (i.e. the quantum oscillator eigenstates) and the Sturm theorem, we derive constraints for a function and its Fourier transform to be both real and positive. We propose a constructive method based on the algebra of Hermite polynomials. Applications are extended to the 2-dimensional case (i.e. Fourier–Bessel transforms and the algebra of Laguerre poly...

For positive diffusions, we construct split-step second-order weak approximations preserving the positivity property. For illustration, we apply the construction to some popular stochastic differential equations such as Verhulst, CIR, and CKLS equations.

No one likes to be given bad news, and a diagnosis of dementia is devastating. How wonderful it would be though if the bad news and negative language stopped at that point. If someone tells you day after day that you’re suffering, you end up believing it. It has a negative impact on your wellbeing. The same would happen if you were told day after day that you are stupid—you end up thinking ther...

Disorders of the brain and its sensory organs have traditionally been associated with deficits in movement, perception, cognition, emotion, and behavior. It is increasingly evident, however, that positive phenomena may also occur in such conditions, with implications for the individual, science, medicine, and for society. This article provides a selective review of such positive phenomena--enha...

Let B be a real vector lattice and a Banach space under a semimonotonic norm. Suppose T is a linear operator on B which is positive and eventually compact, y is a positive vector, and A is a positive real. It is shown that (XI—TY1y is positive if, and only if, y is annihilated by the absolute value of any generalized eigenvector of T* associated with a strictly positive eigenvalue not less than...
