Integration of Radar Sensing into Communications with Asynchronous Transceivers
Clock asynchronism is a critical issue in integrating radar sensing into communication networks. It can cause ranging ambiguity and prevent coherent processing of discontinuous measurements in inte…
New First-Order Algorithms for Stochastic Variational Inequalities
In this paper, we propose two new solution schemes to solve the stochastic strongly monotone variational inequality (VI) problems: the stochastic extra-point solution scheme and the stochastic extr…
Hybrid Sapphire Dual-Fabry—Perot-Cavities Sensor for High Temperature and R…
We presented a hybrid sapphire dual-Fabry-Perot- cavities sensor for high temperature and refractive index measurement. A double-sided polished sapphire solid wafer is connected in series with a do…
Online Learning and Optimization for Revenue Management Problems with Add-on …
We study in this paper a revenue-management problem with add-on discounts. The problem is motivated by the practice in the video game industry by which a retailer offers discounts on selected suppo…
Joint Learning and Optimization for Multi-Product Pricing (and Ranking) Under…
We consider joint learning and optimization problems under a general Cascade Click model. Under this model, customers examine the products in a decreasing order of display, from the top to (potenti…
Local Composite Quantile Regression for Regression Discontinuity
We introduce the local composite quantile regression (LCQR) to causal inference in regression discontinuity (RD) designs. Kai, Li and Zou study the efficiency property of LCQR, while we show that i…
A Unified Framework for Specification Tests of Continuous Treatment Effect Mo…
We propose a general framework for the specification testing of continuous treatment effect models. We assume a general residual function, which includes the average and quantile treatment effect m…
A Synthetic Regression Model for Large Portfolio Allocation
Portfolio allocation is an important topic in financial data analysis. In this article, based on the mean-variance optimization principle, we propose a synthetic regression model for construction o…
The Impact of the COVID-19 Pandemic on the Behavior of Online Gig Workers
Problem definition: Using labor supply data from a large online education platform with more than 100,000 gig workers, we investigate how online gig workers changed their behavior after the outbrea…
A Model of Product Line Marketing
Firms offer a variety of products to meet different customer needs. In many horizontally differentiated markets, prices are stable, and firms make infrequent adjustments to their product lines. Alt…
