In recent studies, global Hopf branches were investigated for delayed model of HTLV-I infection with delay-independent parameters. It is shown in [8, 9] that when stability switches occur, global Hopf branches tend to be bounded, and different branches can overlap to produce coexistence of stable periodic solutions. In this paper, we investigate global Hopf branches for delayed systems with del...

Background: The aim of this study was to classify the left hemiliver medial sector portal branches on the basis of their site of origin and area that supply. The leading motive for this investigation was to contribute to the modern liver practice, especially to the respective and transplantation ones. Methods: The examined material consisted of 27 portobiliary casts performed by injection-corro...

The article provides anatomic information about cervicothoracic ganglion in roe deer. For this purpose 12 cervicothoracic ganglia obtained from the right and left sides of 6 mature roe deer weighing 18-25 kg of both sexes were investigated. Cervicothoracic ganglion was located at the first intercostal space and ventrolateral side of longus colli muscle. This ganglion which was in various forms ...

OBJECTIVES/HYPOTHESIS To better understand the reason for the low success rate of posterior cricoarytenoid (PCA) muscle reinnervation, we attempted to identify the communicating branches that may exist between the nerve branch to the PCA muscle and the other laryngeal adductors in addition to the interarytenoid (IA) muscle. STUDY DESIGN Quantitative histological assessment. METHODS Twenty h...

Dynamic network data envelopment analysis (DNDEA) has attracted a lot of attention in recent years. On one hand the available models in DNDEA evaluating the performance of a DMU with interrelated processes during specified multiple periods but on the other hand they can only measure the efficiency of dynamic network structure when a supply chain structure present. For example, in the banking in...

We consider the optimal dividend problem in so-called degenerate bivariate risk model under assumption that surplus of one branch may become negative. More specific, we solve stochastic control maximizing discounted dividends until simultaneous ruin both branches an insurance company by showing value function satisfies a certain Hamilton–Jacobi–Bellman (HJB) equation. Further, prove is smallest...
