Neuro-fuzzy Control Is Sometimes Better than Crisp Control

The objective of this work is to present some results concerning the neuro-fuzzy control synthesis as applied to electrohydraulic servomechanisms actuating primary flight controls. This represents a remarkable control strategy, with antisaturating and antichattering properties, which is in fact independent of mathematical model of the system, thus achieving certain robustness and reducing compl...

Sometimes, more is better.

(See the article by El Sahly et al, on pages 703–12.) Influenza causes significant morbidity and mortality with an estimated 36 000 attributable deaths in the United States annually [1]. Human immunodefi-ciency virus (HIV) infection, specifically , advanced disease (CD4 count ,200 cells/lL), has been associated with excess morbidity and mortality [2]. With the use of combination antiretroviral ...

Heterochromatin Replication: Better Late Than Ever

Different heterochromatic properties appear on satellite DNA during successive embryonic division cycles in Drosophila. One such property, late replication, precedes HP1 recruitment, is under the control of zygotic transcription, and helps to lengthen S phase.

Is more always better

Is more always better? We address this question in the context of bibliometric indices that aim to assess the scientific impact of individual researchers by counting their number of highly cited publications. We propose a simple model in which the number of citations of a publication depends not only on the scientific impact of the publication but also on other ‘random’ factors. Our model indic...
