The long-term development of mobile banking (m-banking) relies on users’ continued usage. Motivated by the need to better understand the motivations and barriers of users’ continuance intention towards m-banking, this study develops a research model based on the incorporation of the technology acceptance model (TAM): task-technology fit model (TTF) and perceived risk into the expectance-confirmation model (ECM). Empirical data from 434 users who had prior experience with m-banking were tested against the proposed research model by using structural equation modeling (SEM). The results indicate that satisfaction, perceived usefulness, perceived task-technology fit, and perceived risk are the main predictors of continuance intention, satisfaction, in turn, is determined by confirmation, perceived usefulness, and perceived risk. Perceived usefulness is affected by confirmation, perceived ease of use, and perceived task-technology fit. However, the direct effect of perceived ease of use to continuance intention is not significant. The results also show that gender significantly moderates the effect of perceived risk to continuance intention. Implications of the findings and future research directions are discussed.

A compact and power-efficient serial I/O targeting dense silicon carrier interconnects is reported. Based on expected channel characteristics, the proposed I/O features low-impedance transmitter termination, high-impedance receiver termination, and a receiver with modified DFE with IIR filter feedback (DFE-IIR). The DFE-IIR receiver uses a single additional IIR filter feedback tap to compensate many postcursors without paying the power and area penalty that would be incurred with a conventional high tap-count DFE. Equalization capabilities of the compact I/O at 10 Gb/s are demonstrated over various channels including conventional chip-to-chip and backplane links with half-baud losses of up to 27 dB. Finally, a transmitter-receiver pair operating over a 40-mm on-chip emulated silicon carrier channel was demonstrated to 8.9 Gb/s, at a link power efficiency of 1.9 mW/Gb/s. Index Terms-Backplane channel communication, chip-to-chip communication, compact I/O, continuous-time IIR filter, decision feedback equalizer, serial link, silicon carrier links.

We are interested in entire solutions of the Allen-Cahn equation u − F (u) = 0 which have some special structure at infinity. In this equation, the function F is an even, double well potential. The solutions we are interested in have their zero set asymptotic to 4 half oriented affine lines at infinity and, along each of these half affine lines, the solutions are asymptotic to the one dimensional heteroclinic solution: such solutions are called 4-ended solutions. The main result of our paper states that, for any θ ∈ (0, π/2), there exists a 4-ended solution of the Allen-Cahn equation whose zero set is at infinity asymptotic to the half oriented affine lines making the angles θ, π − θ , π + θ and 2π − θ with the x-axis. This paper is part of a program whose aim is to classify all 2k-ended solutions of the Allen-Cahn equation in dimension 2, for k 2.
