After setting the gold standard for both industrial dropon-demand inkjet printheads and R&D printers for functional materials printing, FUJIFILM Dimatix has developed a printhead with the highest jetting frequency ever obtained. Operating at 100 kHz, the MEMS fabricated SAMBA printhead expands the capabilities of fabrication methods for display applications.

Development of novel conducting polymers (CPs) is expected to facilitate the advancement of functional materials used for energy, environmental, and nanotechnology. Recent research efforts are focused on doping CPs with functional dopants to enhance their performance or add additional functions that are not inherent in CPs. This review surveys literatures about the doped CPs focusing on the roles of functional dopants, unlike other reviews focusing on the development of new conducting polymer backbones. The functional dopants presented in this review include redox active molecules, carbon nanomaterials, biopolymers, and chelating molecules. Depending on the dopants and their physicochemical properties, the doped CPs can be used for a variety of applications such as polymer batteries, membranes for waste water treatment, and chemical sensors. A major challenge of the CPs is presented and the ways to overcome the challenge is also suggested for the future development of stable, high performance CPs.

In this paper, we study ARCH(${\infty}$) models with either geometrically decaying coefficients or hyperbolically decaying coefficients. Most popular autoregressive conditional heteroscedasticity (ARCH)-type models such as various modified generalized ARCH (GARCH) (p, q), fractionally integrated GARCH (FIGARCH), and hyperbolic GARCH (HYGARCH). can be expressed as one of these cases. Sufficient conditions for $L_2$-near-epoch dependent (NED) property to hold are established and the functional central limit theorems for ARCH(${\infty}$) models are proved.

A functional central limit theorem is obtained for a stationary linear process of the form $X_{t}= \sum\limits_{j=0}^\infty{a_{j}x_{t-j}}$, where {x_t} is a strictly stationary sequence of negatively associated random variables with suitable conditions and {a_j} is a sequence of real numbers with $\sum\limits_{j=0}^\infty|a_{j}|<\infty$.

In this paper we investigate a generalization of the Hyers-Ulam-Rassias stability for a functional equation of the form $f(\varphi(X))\;=\;\phi(X)f(X)$, where X lie in n-variables. As a consequence, we obtain a stability result in the sense of Hyers, Ulam, Rassias, and Gavruta for many other equations such as the gamma, beta, Schroder, iterative, and G-function type's equations.

In the present paper, we introduce a new system of functional equations, known as orthogonal Pexider hom-derivation and Pexider hom-Pexider derivation (briefly, (Pexider) hom-derivation). Using the fixed point method, we investigate the stability of Pexider hom-derivations and (Pexider) hom-derivations on Banach algebras.

In this paper, we present a development process model for mobile applications. It consists of five development phases including requirements analysis, architecture design, navigation design, page design, and implementation and testing phase. It provides a design method with diagrams. Our development method helps program developers define functional requirements and design applications architecture and functional flow. Through our method, they can reduce their applications development time and effort. We applied our method to developing a mobile application, and then presented the diagramming products as the result of performing development phases.

Synthetic methods of colloids have been significantly developed in industry due to their significant demand for preparation of functional particles. Recently, dynamic/static microfluidic system has emerged as a promising route to the synthesis of the particles, providing precise control of physical and chemical properties such as size, shape, porosity, surface roughness, and surface functionality. These formed particles can be potentially used in various applications including medical diagnostics, photonic device, and biological industry. In addition, these particles provide a novel route to create new materials via their directed self-assembly, and it enable to study and predict the natural phenomenon by mimicking of the nature. Therefore, we describe recent progress for functional colloid particles and its applications.
