Manipulation Test for Multidimensional RDD

Journal of Applied Econometrics, EarlyView.
ABSTRACT The causal inference model for the regression discontinuity design (RDD) relies on assumptions that imply the continuity of the density of the assignment (running) variable. The test for this implication is commonly referred to as the manipulation test and is regularly reported in applied research to strengthen the design's validity.

A Dual‐Programmable Metasurface with Duplex Beam Steering for Full‐Space Terahertz Communications

Laser &Photonics Reviews, EarlyView.
A dual‐programmable terahertz metasurface enables independent control of transmission and reflection beam steering. It breaks through the limitations in resonant tunability by polarization allocation with 2D‐electron‐gas tuning, enabling a single resonator to incorporate bidirectional operating modes.

Artificial intelligence and physician burnout: A productivity paradox

Learning Health Systems, EarlyView.
Abstract Introduction Physician burnout persists in the American healthcare system. In part, this burnout is believed to be driven by the Electronic Health Record (EHR) and its fraught role in the clinical work of physicians. Artificial intelligence (AI)‐enabled healthcare technologies are often promoted on the basis of their promise to reduce burnout ...

Scheduling Algorithm and Bandwidth Allocation in WiMAX [PDF]

, 2012
The traditional solution to provide high-speed broadband access is to use wired access technologies, such as cable modem, DSL (Digital Subscriber Line), Ethernet, and fiber optic. However, it is too difficult and expensive for carriers to build and maintain wired networks, especially in remote areas.

Cost‐Efficient Detection of Plastics From Post‐Consumer Packaging Waste Using Selected Bands in the Near‐infrared Spectrum

Macromolecular Materials and Engineering, EarlyView.
The proposed method aims to reduce the system complexity of the sensor system for sorting plastic waste by using optical wavelength filters to capture the reflection of specific wavelengths instead of the entire spectra. The study demonstrates the feasibility of distinguishing high‐density polyethylene (HDPE), low‐density polyethylene (LDPE ...

Effective Bandwidth Allocation for WiMAX Mesh Network [PDF]

Journal of Systemics, Cybernetics and Informatics, 2010
The aim of this paper is to reduce the media access delay in a WiMAX mesh network. We observe that as the number of subscriber stations (SS) in a neighborhood increases, the processes of transmission opportunity (TO) competition and 3- way handshake are ...

Minimizing Power Consumption in Video Servers by the Combined Use of Solid-State Disks and Multi-Speed Disks

IEEE Access, 2018
Disks use a considerable portion of the total energy consumed by a video server. Solid-state disks (SSDs) can be used as a cache to reduce disk speeds, thereby decreasing the power consumed by disks.

Strong gradients, cool performance: A 64‐channel array coil with concurrent field monitoring and thermal control for ex vivo diffusion‐weighted brain imaging using the 3T connectome 2.0 MRI scanner

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose High‐resolution ex vivo diffusion‐weighted imaging (dMRI) with high b$$ b $$‐values presents significant challenges, including low signal‐to‐noise ratio (SNR), magnetic field perturbations, and temperature‐related measurement shifts.
