The notion of Steiner visibility graphs is introduced. Their applicability in connection with the construction of good quality suboptimal solutions to the Euclidean Steiner tree problem with obstacles is discussed. Polynomial algorithms generating Steiner visibility graphs are described.
1. Introduction Among sedimentary systems that are rich and poor in terms of sediment load, a different organization of the sand dunes can be seen. Barchan dunes are one of the accumulative landforms of wind that are considered from poor sedimentary systems in desert environments. The dunes are the crescent shape, and have two horns at the end. Along the horns the prevailing wind direction...
Perceived trustworthiness is a critical antecedent of interpersonal trust, yet researchers have a limited understanding of how such perceptions are generated. The authors used 2 competing perspectives within the relational demography literature— similarity–attraction and relational norms—to empirically examine the effect of demographic differences. Whereas the similarity–attraction account sugg...
especially 60-61. An instructive assessment of recent trends in demographic approaches to parish registers is provided by D. E. C. Eversley, 'Exploitation of Anglican Parish Registers by Aggregative Analysis', in WRIGLEY, E. A. (ed.), An Introduction to English Historical Demography, London, 1966. We must also note the recent groundswell of parish register publication efforts. Yet what remains ...
Accumulating evidence is emerging that microRNAs (miRNAs) are key regulators in controlling neuroinflammatory responses that are known to play a potential role in the pathogenesis of temporal lobe epilepsy (TLE). The aim of the present study was to investigate the dynamic expression pattern of interleukin (IL)-10 as an anti-inflammatory cytokine and miR-187 as a post-transcriptional inflammatio...
آزمونهای رئولوژیکی تحت میدان جریان برشی گذار و دینامیک به همراه آزمونهای SAXS، TEM و SEM برای آمیختههای PP/PET با نسبتهای وزنی 75/25 و 25/75 حاوی دو نوع نانوخاکرس مونتموریلونیت با نامهای تجاری کلویزیت 20A و کلویزیت 30B، انجام شد. نسبت وزنی کلویزیت 20A به کلویزیت 30B در نمونههای نانوکامپوزیت آمیخته برابر با نسبت وزنی PP به PET انتخاب شد. نتایج آزمونهای SAXS و TEM نشان داد، تقریباً تمام ن...
Objective(s): Improved brain uptake ratio (IBUR), employing 99mTc-ethyl cysteinate dimer (99mTc-ECD), is an automatic non-invasive method for quantitatively measuring regional cerebral blood flow (rCBF). This method was developed by the reconstruction of the theory and linear regression equation, based on rCBF measurement by H215O positron emission tomography. Clarification of differences in r...
