SOLUTION OF AN UNSOLVED PROBLEM IN BCK-ALGEBRA
Nisar, Farhat,Bhatti, Shaban Ali The Youngnam Mathematical Society Korea 2005 East Asian mathematical journal Vol.21 No.1
In this paper we introduced Semi-neutral BCK-algebra and investigate some of its properties. The notions of ideals and subalgebras coincide in Semi-neutral BCK-algebras. We also show that if the number of nonzero elements in a Semi-neutral BCK-algebra is n, then the number of ideals/subalgebras in it is $2^n$. Further, we solved an open problem posed by W.A. Dudek in [2].

In this research study, a highly selective and sensitive electrochemical sensor was designed by coating the glassy carbon electrode (GCE) with the novel PANI/MOF-199/Ag nanocomposite for the non-enzymatic electrochemical detection of dopamine (DA). PANI/MOF-199/Ag nanocomposite was prepared by the in situ chemical oxidative polymerization of aniline monomer in the presence of MOF-199 followed by the deposition of Ag nanoparticles using an in situ chemical reduction route. Characterization techniques such as Scanning electron microscopy (SEM), X-ray powder diffraction (XRD), Fourier transform infra-red spectroscopy (FTIR), and Raman analysis were used to find out the successful synthesis of the prepared samples. Meanwhile, the electrochemical performance was investigated by chronoamperometry (CA) and cyclic voltammetry (CV) not only at different molar concentrations of DA but also with various compositions of Ag nanoparticles loaded. The PANI/MOF-199/Ag-3% modified electrode exhibited good electro-catalytic activity with high sensitivity of 1.421 μA μM−1 cm− 2 and a low detection limit (LOD) of 0.22 μM (S/N = 3) towards DA. Moreover, in the presence of common interfering biological compounds such as glucose (Glu), uric acid (UA), and ascorbic acid (AA), the fabricated electrochemical sensor was found selective to DA detection.

We aim to establish certain Gronwall type inequalities associated with Riemann-Liouville k- and Hadamard k-fractional derivatives. The results presented here are sure to be new and potentially useful, in particular, in analyzing dependence solutions of certain k-fractional differential equations of arbitrary real order with initial conditions. Some interesting special cases of our main results are also considered.

Nisar, Kottakkaran Sooppy Korean Mathematical Society 2017 대한수학회논문집 Vol.32 No.4
The recent research investigates the generalization of Bessel function in different forms as its usefulness in various fields of applied sciences. In this paper, we introduce a new modified form of k-Bessel functions called the generalized modified k-Bessel functions and established some of its properties.

<P><B>Abstract</B></P> <P>LiNi<SUB>0.5</SUB>Mn<SUB>1.5</SUB>O<SUB>4</SUB> is a promising high-voltage cathode for lithium-ion battery fast charging applications. Aware of its electrochemical stability issues, the material's surface is modified with small amounts of zirconia (ZrO<SUB>2</SUB>) ranging from 0.5 to 2 wt% using a scalable ball milling process. The advantage of the coating has been demonstrated in electrochemical measurements performed at room temperature and 55 °C, and in cells discharged under high-rate conditions up to 80C. Of significance, the material coated with 1.0 wt% ZrO<SUB>2</SUB> has been cycled at the 40C rate for over a thousand cycles and retains 86% of its initial capacity. The material with 2.0 wt% ZrO<SUB>2</SUB> modification preserves 76% of its initial capacity when cycled at the 40C rate and 55 °C. The coated materials have shown excellent cycling stability when subjected to 6C (10-min) fast charging and C/3 discharging for 300 cycles. Compared to the uncoated material, the interfacial resistance of the zirconia modified LiNi<SUB>0.5</SUB>Mn<SUB>1.5</SUB>O<SUB>4</SUB> has been found to be much lower and does not significantly increase with increasing the coating amount. However, the electrochemical performances are still partly limited by both interfacial resistance at the beginning of charge and electrolyte diffusivity, particularly under higher rate cycling conditions. Overall, the strategy of ZrO<SUB>2</SUB> surface modification applied to LiNi<SUB>0.5</SUB>Mn<SUB>1.5</SUB>O<SUB>4</SUB> unveils the potential that the material could play in extreme fast charged electric vehicles.</P> <P><B>Highlights</B></P> <P> <UL> <LI> ZrO<SUB>2</SUB>-LiNi<SUB>0.5</SUB>Mn<SUB>1.5</SUB>O<SUB>4</SUB> withstands 80C-rate and demonstrates over thousand cycles at 40C. </LI> <LI> Charge transfer resistance at LiNi<SUB>0.5</SUB>Mn<SUB>1.5</SUB>O<SUB>4</SUB>/electrolyte is stable with coating. </LI> <LI> Origin of high-rate capability is correlated with the high kinetics at the material's interfaces. </LI> <LI> Surface modification of LiNi<SUB>0.5</SUB>Mn<SUB>1.5</SUB>O<SUB>4</SUB> enables extreme fast charging. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

<P>We search for the rare radiative decay D-0 -> gamma gamma using a data sample with an integrated luminosity of 832 fb(-1) recorded by the Belle detector at the KEKB e(+)e(-) asymmetric-energy collider. We find no statistically significant signal and set an upper limit on the branching fraction of B(D-0 -> gamma gamma) < 8.5 x 10(-7) at 90% confidence level. This is the most restrictive limit on the decay channel to date.</P>
