Rank Bounded Hibi Subrings for Planar Distributive Lattices [PDF]
, 2019 Let $L$ be a distributive lattice and $R[L]$ the associated Hibi ring. We show that if $L$ is planar, then any bounded Hibi subring of $R[L]$ has a quadratic Gr\"obner basis.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics
Advanced Materials, EarlyView.The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Szász-Baskakov type operators based on q-integers
Journal of Inequalities and Applications, 2014 In the present paper, we introduce the q-analog of the Stancu variant of Szász-Baskakov operators. We establish the moments of the operators by using the q-derivatives and then prove the basic convergence theorem.

On quantum state of numbers [PDF]
, 2013 We introduce the notions of quantum characteristic and quantum flatness for arbitrary rings. More generally, we develop the theory of quantum integers in a ring and show that the hypothesis of quantum flatness together with positive quantum ...

Two new triangles of q-integers via q-Eulerian polynomials of type A and B [PDF]
, 2012 The classical Eulerian polynomials can be expanded in the basis tk−1(1+t)n+1−2k (1≤k≤⌊(n+1)/2⌋) with positive integral coefficients. This formula implies both the symmetry and the unimodality of the Eulerian polynomials.

Advanced Materials, EarlyView.This study reports the fabrication of MRI‐compatible elastomeric micro‐balloons via a multi‐step bubble casting process, where the monolithic elastomeric wall is selectively stiffened for reversible and controlled inflation and elasticity, depending on the target vessels for graded occlusion of cerebral arteries.

Graphene‐Based Wearable Textile Triboelectric Nanogenerators and Biomechanical Sensors
Advanced Materials Technologies, EarlyView.This study presents a wearable textile‐based triboelectric nanogenerator (T‐TENG) using sprayed graphene enhanced with a PVA adhesion layer. The graphene‐based electrode demonstrates high electrical conductivity and robustness to multiple bends. The fabricated T‐TENG provides stable and efficient output, with strong responsiveness to biomotion.

A note on the alternating sums of powers of consecutive q-integers [PDF]
, 2005 In this paper we construct a new q-Euler numbers and polynomials. By using these numbers and polynomials, we give the interesting formulae related to alternating sums of powers of consecutive q-integers following an idea due to Euler.

Advanced Optical Materials, EarlyView.Whispering‐gallery‐mode microresonators with sharp resonant peaks enable photonic barcoding. Similar to a chameleon, a rare‐earth‐free microcavity with π‐conjugated PAHs enables visibleto‐near infrared color generation from a single microbead. The unique resonat emission (spectral barcode) can be dynamically transformed via excitation wavelength change,

On convergence properties of gamma-Stancu operators based on q-integers
, 2016 . In this paper we introduce Stancu type generalization of Gamma operators based on the concept of q -integers. We fi rst establish local approximation theorems for these operators.
