According to the strange quark matter hypothesis, pulsars may actually be stars composed of self-bound matter. The normal crust a star, unlike that neutron is supported by strong electric field. A gap then presented between and core. Therefore, peculiar core-crust oscillation occur in which can produce distinctive gravitational waves. In this paper, waveforms such waves are derived using rigid ...

We develop a Hamiltonian analytical theory for the rotation of Poincaré Earth model (rigid mantle and liquid core) at second order with respect to lunisolar potential moving ecliptic term. Since Andoyer variables considered in first-order solution present virtual singularities, i.e., vanishing divisors, we introduce set nonsingular complex canonical variables. This choice allows applying Hori p...

The analysis of the spatial structure of a rigid polyphenylene dendrimer G4-M of fourth generation by small-angle neutron scattering (SANS) is presented. This dendrimer is composed of phenyl units and is therefore devoid of any flexible unit. The scattering intensity of dilute solutions of the dendrimer was measured by SANS at different contrast which was adjusted by mixtures of protonated and ...

Homoconjugation is a phenomenon discussed for various ?-systems where classical conjugation broken by e.g. methylene units but still stabilization electronic communication exists. In this respect, triptycene with its rigid C3 symmetric geometry an ideal scaffold to study phenomenon. Although several studies based on strengthen the hypothesis of homoconjugation, in all described cases through sp...

The present work deals with analyses of the effects of bearing curvature and non-Newtonian characteristics on the load capacity of an exponential rectangular squeeze film bearing using Bingham fluids as lubricants. Bingham fluids are characterized by an yield value and hence the formation of a “rigid” core in the region between the plates is justified. The flow is confined to the region between...

In the holographic model of QCD suggested by Sakai and Sugimoto, baryons are chiral solitons sourced by D4 instantons in bulk of size 1/ √ λ with λ = gNc. We quantize the D4 instanton semiclassically using ~ = 1/(Ncλ) and non-rigid constraints on the vector mesons. The holographic baryon is a small chiral bag in the holographic direction with a Cheshire cat smile. The vector-baryon interactions...

Four Organic Molecules of Intrinsic Microporosity (OMIMs) were prepared by fusing triptycene-based components to a biphenyl core. Due to their rigid molecular structures that cannot pack space efficiently, these OMIMs form amorphous materials with significant microporosity as demonstrated by apparent BET surface areas in the range of 515-702 m(2) g(-1). Bulky cyclic 1',2',3',4'-tetrahydro-1',1'...
