Starting from optical nihility media (ONM),we design several intriguing devices with transformation optics method in two dimensions,such as a wave splitter,a concave lens,a field rotator,a concentrator,and an invisibi...
Henry Purcell(1659-1695)and Benjamin Britten(1913-1976)are the main figures in English musical culture.Britten was particularly inspired by Purcell’s illustrative approach to putting together music and text,thus crea...
Maheshwari has proposed three differential-voltage current-conveyor configurations for realizing first order all-pass filters only. This paper has exploited these configurations for realizing more complex transfer fun...
Based on the role of the polynomial functions on the homogeneous Besov spaces, on the homogeneous Triebel-Lizorkin spaces and on their realized versions, we study and obtain characterizations of these spaces via diffe...
Starting from Wigner’s definition of the function named now after him we systematically develop different representation of this quasiprobability with emphasis on symmetric representations concerning the canonical va...
New voltage-controlled floating inductors employing CFOAs and an analog multiplier have been presented which have the attractive features of using a canonic number of passive components (only two resistors and a capac...

The possible supersymmetric kinematics are presented by the contraction method in different limits from Beltrami–Mc Keon–Schubert realizations of osp(1|4). The connections among the superalgebras are established. Th...
The nonlinear affine Goldstone model of the emergent gravity, built on the nonlinearly realized/ hidden affine symmetry, is concisely revisited. Beyond General Relativity, the explicit violation of general invariance/...
