This article introduces a new model called the buffered autoregressive model with generalized autoregressive conditional heteroscedasticity (BAR-GARCH). The proposed model, as an extension of the B…
We investigate a firm’s optimal product portfolio design on a Hotelling line that can affect consumers’ search decisions. Consumers form their perceptions of a brand from interactions with all …
A silicon photonic based transmitter and receiver chipset for 4×106Gb/s 400 GBASE-DR4 data rates is presented. Each channel of the transmitter chip reaches high extinction ratio and optical modula…
This article presents a novel scheme based on underwater optical wireless communication and positioning (UOWC-UOWP) for an underwater wireless sensor network (UWSN). A dual-hop system is adopted to…
It is foreseeable that the 100 Gb/s/ λ and beyond passive optical network (PON) will be required in future optical access networks to meet the explosive growth of data traffic. The coherent optica…
We show that firms strategically alter their disclosures when investors’ access to information via search engines is interrupted. We conduct a textual analysis and exploit an exogenous event—Go…
The discovery of different types of nanomaterials including the one-dimensional and two-dimensional materials used as saturable absorbers (SAs) in the applications of ultrafast lasers in recent yea…
Single-index quantile regression (QR) models can avoid the curse of dimensionality in nonparametric problems by assuming that the response is only related to a single linear combination of the cova…
Handling constrained multiobjective optimization problems (CMOPs) is extremely challenging, since multiple conflicting objectives subject to various constraints require to be simultaneously optimiz…
Very deep Convolutional Neural Networks (CNNs) have greatly improved the performance on various image restoration tasks. However, this comes at a price of increasing computational burden, hence lim…
