AbstractCombinatorial designs provide an interesting source of optimization problems. Among them, permutation codes are particularly given their applications in powerline communications, flash memories, and block ciphers. This paper addresses the design by evolutionary algorithms (EA) developing iterative approach. Starting from a single random permutation, new permutations satisfying minimum d...

Which means that SVV (%) ≈ pulse pressure variation (PPV; %) for FloTracTM. With the present mathematical equation, it can be demonstrated that the SVV calculated by FloTracTM (SVVFT) is not infl uenced by Khi, which means that SVVFT calculation does not include eff ective arterial elastance (Ea). Th e originality of Garcia and colleagues’ fi nding is that they realized that when measuring PPV ...

The physiology of conduit arteries can be approximated noninvasively. One simple method to estimate arterial load is by computation of effective arterial elastance (Ea). Ea incorporates the steady component (peripheral resistance) and the pulsatile components of arterial load, including total arterial compliance and aortic characteristic impedance. Invasive studies and simulations have shown th...

AIM To observe the effect of electroacupuncture (EA) of "Neiguan" (PC6) and "Gongsun" (SP4) on pathological changes of the heart and stomach in rats with acute myocardial ischemia (AMI), and to explore its underlying mechanism. METHODS Fifty Wistar rats were randomized into control, model, PC6, SP4 and PC6 + SP4 groups (n = 8 each group). An AMI model was established by occlusion of the desce...

This thesis presents the Situation-Based Modeling Framework for Enterprise Architecture. This framework improves system modeling by making models more systemic and, therefore, making reasoning about these models easier. The context of this thesis is Enterprise Architecture (EA). EA enables enterprises to anticipate or react to necessary business or technical changes. EA models have to represent...

The present work aimed to evaluate the effectiveness of Plectranthus amboinicus (Lour.) Spreng against MRSA clinical isolates. The in vitro antimicrobial activity of the hydroalcoholic extract (HE), the ethyl acetate (EA) fraction and its subfractions were determined by broth microdilution and bioautography against MRSA clinical isolates. The microdilution checkerboard method was used to assess...

Objective. To investigate the effect of EA on regional cerebral blood flow, cognitive deficits, inflammation, and its probable mechanisms in chronic cerebral ischemia (CCI) rats. Methods. Rats were assigned randomly into sham operation group (sham group) and operation group. For operation group, CCI model was performed using the permanent bilateral common carotid artery occlusion (BCCAO) method...
