Enhanced capacitive behaviour of graphene based electrochemical double layer capacitors by etheric substitution on ionic liquids
Siyahjani, Shirin; Oner, Saliha; Diker, Halide; GÜLTEKİN, BURAK; Varlikli, Canan (Elsevier BV, 2020-08-01)
In this study, we report the effect of etheric substituents in imidazolium and ammonium based ionic liquids (IL) on the performance of electrochemical double layer capacitors (EDLC) consisted of gel polymer electrolyte (GP...
On a Problem of Erdos and Graham
Yildiz, Burak; Gurel, Erhan (Springer Science and Business Media LLC, 2020-06-01)
An old conjecture of Erdos and Graham states that only finitely many integer squares could be obtained from product of disjoint blocks of consecutive integers of length greater than or equal to four. It is known by counter...
TANNAKIAN CLASSIFICATION OF EQUIVARIANT PRINCIPAL BUNDLES ON TORIC VARIETIES
Biswas, Indranil; Dey, Arijit; Poddar, Mainak (Springer Science and Business Media LLC, 2020-03-01)
LetXbe a complete toric variety equipped with the action of a torusT, andGa reductive algebraic group, defined over an algebraically closed fieldK. We introduce the notion of a compatible n-ary sumation -filtered algebra a...
REGULARITY OF QUOTIENTS OF DRINFELD MODULAR SCHEMES
Kondo, Satoshi; Yasuda, Seidai (Mathematical Sciences Publishers, 2020-02-01)
Let A be the coordinate ring of a projective smooth curve over a finite field minus a closed point. For a nontrivial ideal I subset of A, Drinfeld defined the notion of structure of level I on a Drinfeld module.
Long-time behaviour of solutions to a singular heat equation with an application to hydrodynamics
Kitavtsev, Georgy; Taranets, Roman M. (European Mathematical Society Publishing House, 2020-01-01)
In this paper, we extend the results of [8] by proving exponential asymptotic H-1-convergence of solutions to a one-dimensional singular heat equation with L-2-source term that describe evolution of viscous thin liquid she...
Quantum system structures of quantum spaces and entanglement breaking maps
Dosi, A. A. (IOP Publishing, 2019-07-01)
This paper is devoted to the classification of quantum systems among the quantum spaces. In the normed case we obtain a complete solution to the problem when an operator space turns out to be an operator system. The min an...
The quantum centripetal force on a free particle confined to the surface of a sphere and a cylinder
Shikakhwa, M. S. (2019-04-01)
The momentum operator for a spin-less particle when confined to a 2D surface embedded into 3D space acquires a geometrical component proportional to the mean curvature that renders it Hermitian. As a consequence, the quant...
Operator Hilbert Systems
Dosi, A. (Pleiades Publishing Ltd, 2019-04-01)
The present note deals with operator Hilbert systems, which are quantizations of unital cones in Hilbert spaces. One central result of the note is that the Pisier operator Hilbert space is an operator system whose quantum ...
String-Theory Realization of Modular Forms for Elliptic Curves with Complex Multiplication
Kondo, Satoshi; Watari, Taizan (Springer Science and Business Media LLC, 2019-04-01)
It is known that the L-function of an elliptic curve defined over Q is given by the Mellin transform of a modular form of weight 2. Does that modular form have anything to do with string theory? In this article, we address...
Cobalt Metallopeptide Electrocatalyst for the Selective Reduction of Nitrite to Ammonium
Guo, Yixing; Stroka, Jesse R.; Kandemir, Banu; Dickerson, Claire E.; Bren, Kara L. (American Chemical Society (ACS), 2018-12-12)
A cobalt-tripeptide complex (CoGGH) is developed as an electrocatalyst for the selective six-electron, eight-proton reduction of nitrite to ammonium in aqueous buffer near neutral pH. The onset potential for nitrite reduct...
Microwave Energy Harvesting by using a Broadband Fractal Antenna and a Dual-Band Rectifier
Ozdemir, Huriye; Nesimoglu, Tayfun (2018-11-02)
In this paper, a broadband rectenna for radio frequency (RF) energy harvesting is presented. The proposed rectenna consists of a broadband fractal slot antenna and a voltage doubler rectifier circuit with a novel matching ...
Ring symmetry in electric potential calculation extended to discs and cylinders
Charyyev, A.; Shikakhwa, M. S. (IOP Publishing, 2018-11-01)
The electric potential-but not the electric field-of any charge distribution on a ring at a point on its axis is equivalent to that of an equal point charge placed anywhere on the ring; this is the well-known ring symmetry...
Investigating the effect of wearing the hijab: Perception of facial attractiveness by Emirati Muslim women living in their native Muslim country
Sheen, Mercedes; Yekani, Hajar Aman Key; Jordan, Timothy R. (Public Library of Science (PLoS), 2018-10-05)
The Hijab and other forms of Islamic veiling are important social, cultural, and religious symbols that are central to the identity of millions of Muslim women across the world. However, despite the large body of literatur...
Multinormed semifinite von Neumann algebras, unbounded operators and conditional expectations
Dosi, Anar (Elsevier BV, 2018-10-01)
The present paper is devoted to classification of multinormed W*-algebras in terms of their bounded parts. We obtain a precise description of the bornological predual of a multinormed W*-algebra, which is reduced to a mult...
On equivariant Serre problem for principal bundles
Biswas, Indranil; Dey, Arijit; Poddar, Mainak (World Scientific Pub Co Pte Lt, 2018-08-01)
Let E-G be a Gamma-equivariant algebraic principal G-bundle over a normal complex affine variety X equipped with an action of Gamma, where G and Gamma are complex linear algebraic groups. Suppose X is contractible as a top...
A categorical approach to the maximum theorem
Koudenburg, Seerp Roald (2018-08-01)
Berge's maximum theorem gives conditions ensuring the continuity of an optimised function as a parameter changes. In this paper we state and prove the maximum theorem in terms of the theory of monoidal topology and the the...
Quantum Cones and Quantum Balls
Dosi, A. (2018-07-01)
The present note is dedicated to description of quantum systems among the quantum spaces. In the normed case we obtain a complete solution to the problem when an operator space turns out to be an operator system. The min a...

Hallajzadeh, J.; Khoramdad, M.; Izadi, N.; Karamzad, N.; Almasi-Hashiani, A.; Ayubi, E.; Qorbani, M.; Pakzad, R.; Sullman, M. J. M.; Safiri, S. (2018-05-01)
Objectives: Based upon inflammatory-related factors in chronic systemic lupus erythematosus (SLE), as well as the long-term prescription of corticosteroids, metabolic syndrome (MetS) prevalence is expected to be higher in ...
Spin force and torque in non-relativistic Dirac oscillator on a sphere
Shikakhwa, M. S. (2018-03-30)
The spin force operator on a non-relativistic Dirac oscillator (in the non-relativistic limit the Dirac oscillator is a spin one-half 3D harmonic oscillator with strong spin-orbit interaction) is derived using the Heisenbe...

Hallajzadeh, Jamal; Khoramdad, Maliheh; Karamzad, Nahid; Almasi-Hashiani, Amir; Janati, Ali; Ayubi, Erfan; Pakzad, Reza; Sullman, Mark J. M.; Safiri, Saeid (Maad Rayan Publishing Company, 2018-01-01)
Introduction: The objectives of this study were to provide an estimate of the prevalence of metabolic syndrome (MetS) and its components among women with PCOS; and calculate the odds ratio (OR) for MetS (using different de...
