Problem definition: Smart contract improves the supply chain efficiency by enabling the supplier’s commitment to postshipment financing decisions, which mitigates the bank’s lending risk exposu…
Many panel data have the latent subgroup effect on individuals, and it is important to correctly identify these groups since the efficiency of resulting estimators can be improved significantly by …
A/B testing, or online experiment is a standard business strategy to compare a new product with an old one in pharmaceutical, technological, and traditional industries. Major challenges arise in on…
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…
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused over six million deaths in the ongoing COVID-19 pandemic. SARS-CoV-2 uses ACE2 protein to enter human cells, raising a pressi…
Multiview stereopsis (MVS) methods, which can reconstruct both the 3D geometry and texture from multiple images, have been rapidly developed and extensively investigated from the feature engineerin…
Problem definition: This paper empirically investigates how customer email engagement affects the profitability of subscription service providers and retailers. They have been using email engagemen…
A Sagnac interferometer based optical fiber ultraviolet (UV) sensor is theoretically proposed and experimentally demonstrated in this work. A layer of ZnO film was deposited upon the surface of a s…
We propose and demonstrate a single fiber optical tweezer for particle multi-dimensional arrangement based on an optical bottle beam produced by concatenating a few-mode fiber and a step-index mult…
In this paper, we propose and demonstrate a photosensitive polymer-based micro-nano long-period fiber grating (PPMN-LPFG) for refractive index (RI) sensing. We coat liquid photosensitive polymer on…
