The Amalgam spaces W(Lp(x),{pn} ) and boundedness of hardy–littlewood maximal operators
(Springer, 2015)Let Lq(x)(R)Lq(x)(R) be variable exponent Lebesgue space and ℓ{qn}ℓ{qn} be discrete analog of this space. In this work we define the amalgam spaces W(L p(x),L q(x)) and W(Lp(x),ℓ{qn})W(Lp(x),ℓ{qn}), and discuss some basic ... 
Analysis of the thermal expansivity near the tricritical point in dilute chromium alloys
(American Institute of Physics, 2016)Chromium (Cr) undergoes a first order Neel transition as an antiferromagnetic material. When V, Mo and Mn atoms are substituted in the Cr lattice, a weak first order Neel transition in pure Cr changes toward a second order ... 
Automorphisms of aut(A),A a free abelian group
(Taylor & Francis, 2015)We prove that all automorphisms of the automorphism group of an infinitely generated free abelian group are inner. 
Bilinear multipliers of weighted Wiener amalgam spaces and variable exponent Wiener amalgam spaces
(Springer, 2014)Let ω1, ω2 be slowly increasing weight functions, and let ω3 be any weight function on Rn. Assume that m(ξ ,η) is a bounded, measurable function on Rn × Rn. We define Bm(f, g)(x) = Rn Rnˆ f(ξ )gˆ(η)m(ξ ,η)e2πiξ+η,x dξ dη ... 
Calculation of the Raman frequencies as a function of pressure in the solid phases II and III (III’) of benzene
(Springer, 2013)We calculate here the Raman frequencies of the lattice modes A(Ag), B(B2g) and C(B1gB3g) as a function of pressure at room temperature for the solid phases (II, III and III’) of benzene. This calculation is performed using ... 
Calculation of the Raman frequencies as a function of temperature in phase I of benzene
(Journal of Indian Chemical Society, 2013)This study gives our calculation of the Raman frequencies of the lattice modes A (A1g), B (AgB2g) and C (B1gB3g) as a function of temperature at constant pressures of 0, 1.4 and 3.05 GPa for the solid phase I of benzene. ... 
Calculation of the Raman frequency shifts for the α phase of solid oxygen
(Elsevier, 2017)We calculate in this study the Raman frequencies of the two librons and one vibron at various pressures at constant temperatures of 10 K and also at the temperatures of 6 and 18 K by using the volume data from the literature ... 
Calculation of the softmode frequency for the alpha – beta transition in quartz
(Elsevier, 2016)The α – β structural transition occurs in quartz at TC = 846 K. The frequency of the soft mode associated with the volume increase, decreases with increasing temperature as the transition temperature is approached. In this ...

Highorder harmonic generation from confined Rydberg atoms
(IOP Publishing, 2015)We report results from our simulations of High Harmonic Generation (HHG) from a confined atom in a Rydberg state. We find that for the n = 2 excited state of H the cutoff of the harmonic spectrum is substantially extended ... 
Highorder harmonic generation from Rydberg states at fixed Keldysh parameter
(Institute for Scientific Information, 2013)Because the commonly adopted viewpoint that the Keldysh parameter γ determines the dynamical regime in strong field physics has long been demonstrated to be misleading, one can ask what happens as relevant physical parameters, ... 
Modelling of swelling by the fluorescence technique in kappa carrageenan gels
(American Institute of PhysicsAIP Conference Proceedings, 2011)Kappa () carrageenan gels prepared with various carrageenan concentrations in pure water were completely dried and then swelled in water vapor. Steady state fluorescence measurements were performed using a spectrometer ... 
Molar volume calculated at various pressures and the Pippard relations close to the melting point in benzene
(Taylor & Francis, 2016)The molar volume of solid and liquid benzene was calculated at various pressures (at constant temperatures), and the Pippard relations were examined close to the melting point in this organic molecule. The molar volume ... 
A note on the order bidual of falgebras
(Hikari, 2013)The paper deals with the Arens Multiplication which we accomplished in four steps in the order bidual ~ ~ X . It is shown that if f is an element of order dual ~ X of X with ε ( f )≠0 and , + x ∈ X then f .x = 0 implies f (x)= . 
On the outer automorphism groups of free groups
(Elsevier, 2014)We prove that the outer automorphism group of a free group of countably infinite rank is complete. 
On the weighted variable exponent amalgam space W(LP(X) , LM(Q))
(Elsevier, 2014)In [4], a new family W(Lp(x), Lm(q))of Wiener amalgam spaces was defined and investigated some properties of these spaces, where local component is a variable exponent Lebesgue space Lp(x) (R) and the global component ... 
Phasedependent interference fringes in the wavelenght scaling of harmonic efficiency
(American Physical Society, 2014)We describe phasedependent wavelength scaling of highorder harmonic generation efficiency driven by ultrashort laser fields in the midinfrared. We employ both numerical solution of the timedependent Schr¨odinger ... 
Pippard relation close to the alpha  beta transition for quartz in granite
(American Institute of Physics, 2016)In this study, we examine variation of the thermal expansion αp with the isothermal compressibility KT at various temperatures (1 atm) close to the αβ transition in quartz using the experimental data from the literature. ... 
Pressure effect on the cholesteric – smectic A transition in cholestryl myristate
