The paper focuses on the uncertainty inherent in the ornamentation/structure pair and on the role of uncertainty in characterizing style. We suggest that the ornamentation/structure pair be viewed as "complementary opposites" that fullll three conditions: contradiction, support and identiication. In computer simulations we perform a detailed harmonic analysis of a Prelude by J.S.Bach and sugges...

We introduce $$\mu $$ -scalar curvature for a Kähler metric with moment map and start up study on constant as generalization of both cscK Kähler–Ricci soliton continuity path to extremal metric. some fundamental constraints the existence by investigating volume functional Tian-Zhu’s work, which is closely related Perelman’s W-functional. A new K-energy studied an approach uniqueness problem pre...

education. Today, a qualitative movement toward efficient trainings ineducational systems is necessary, since one of the important factors in the development and progress of any society is necessarily resources, manpower and their education.Considering education as a basic system in growing human resources, the present article tries to address this matter, due to the fact that we are in a situ...

Either to sustain autotrophy, or as a prelude to heterotrophy, organic synthesis from an environmentally available C1 feedstock molecule is crucial to the origin of life. Recent findings augment key literature results and suggest that hydrogen cyanide--"Blausäure"--was that feedstock.

We review and pay tribute to a result on convergent systems by the Russian mathematician Boris Pavlovich Demidovich. In a sense, Demidovich’s approach forms a prelude to a 7eld which is now called incremental stability of dynamical systems. Developments on incremental stability are reviewed from a historical perspective. c © 2004 Elsevier B.V. All rights reserved.
