PURPOSE To compare the effectiveness of toric foldable iris-fixated phakic intraocular lens (pIOL) implantation and non-toric foldable iris-fixated pIOL implantation with limbal relaxing incisions (LRIs) for correcting moderate-to-high astigmatism in myopic eyes. MATERIALS AND METHODS The medical records of 146 patients (195 eyes) with myopic astigmatism who underwent toric foldable iris-fixa...

Almost toric manifolds form a class of singular Lagrangian fibered symplectic manifolds that is a natural generalization of toric manifolds. Notable examples include the K3 surface, the phase space of the spherical pendulum and rational balls useful for symplectic surgeries. The main result of the paper is a complete classification up to diffeomorphism of closed almost toric four-manifolds. A k...

In this note we derive a formalism for describing equivariant sheaves over toric varieties. This formalism is a generalization of a correspondence due to Klyachko, which states that equivariant vector bundles on toric varieties are equivalent to certain sets of filtrations of vector spaces. We systematically construct the theory from the point of view of graded ring theory and this way we consi...

In this paper, we study the minimal free resolution of lex-ideals over a Koszul toric ring. In particular, we study in which toric ring R all lexideals are componentwise linear. We give a certain necessity and sufficiency condition for this property, and show that lex-ideals in a strongly Koszul toric ring are componentwise linear. In addition, it is shown that, in the toric ring arising from t...

purpose: to evaluate the efficacy and safety of the artisan phakic intraocular lens (piol) for the correction of high myopia. methods: in this prospective study of 22 eyes of 14 patients with high myopia, artisan piols (ophtec bv) were implanted. uncorrected visual acuity (ucva), best corrected visual acuity (bcva), refraction, astigmatism, safety, and predictability were analyzed. results: the...

purpose : to evaluate the efficacy, safety, predictability and stability of implantable collamer lens (icl) and toric icl for the treat­ment of high myopia and high myopic astigmatism methods : in this prospective nonrandomized clinical trial, 95 eyes of 51 patients who underwent icl (31 eyes) and toric icl (64 eyes) implantations were participate in eye research center, department of ophthalmo...

The mathematical modelling of genetic-metabolic networks is of outmost importance in the field of systems biology. Different formalisms and a huge variety of classical mathematical tools have been used to describe and analyse such networks. Michael A. Savageau defined a formalism to model genetic-metabolic networks called S-Systems, [16], [17], [19]. There is a limit in the number of nodes that...
