The first group is the one considered in the literature as that of "strabismus with anomalous correspondence". Must we consider the "anomalous correspondence" of these subjects as a system of corresponding ret...

Results:After 12weeks of treatment, theOBVAT group’s mean Convergence Insufficiency Symptom Survey score (15.1) was statistically significantly lower than those of 21.3, 24.7, and 21.9 in the HBCVAT , HBPP, andOBPT groups, respectively (P .001). The OBVAT group also demonstrated a significantly improved near point of convergence and positive fusional vergence at near compared with the other gro...

A b s t r a c t In this paper, we briefly discuss the dynamic and functional approach to computer symbolic tensor analysis. The ccgrg package for Wolfram Language/Mathematica is used to illustrate this approach. Some examples of applications are attached.

In this article, we propose a fuzzy class relation assigning to each pair of finite fuzzy sets a degree to which they are equipollent, which indicates that they have the same number of elements. The concepts of fuzzy sets and fuzzy classes in the class of all countable sets are introduced, and several standard relations and constructions, such as the fuzzy power set and exponentiation, are defi...
