Exciton Transport in a Germanium Quantum Dot Ladder

Quantum systems with engineered Hamiltonians can be used to study many-body physics problems to provide insights beyond the capabilities of classical computers. Semiconductor gate-defined quantum dot arrays have emerged as a versatile platform for realizing generalized Fermi-Hubbard physics, one of the richest playgrounds in condensed matter...

EFE: End-to-end Frame-to-Gaze Estimation

Despite the recent development of learning-based gaze estimation methods, most methods require one or more eye or face region crops as inputs and produce a gaze direction vector as output. Cropping results in a higher resolution in the eye regions and having fewer confounding factors (such as clothing and hair) is believed to benefit the final...

GazeNeRF: 3D-Aware Gaze Redirection with Neural Radiance Fields

We propose GazeNeRF, a 3D-aware method for the task of gaze redirection. Existing gaze redirection methods operate on 2D images and struggle to generate 3D consistent results. Instead, we build on the intuition that the face region and eyeballs are separate 3D structures that move in a coordinated yet independent fashion. Our method leverages...

Case Study of the Largest Concrete Earth Pressure Balance Pipe-Jacking Project in the World

Pipe jacking has been the dominant trenchless technology for constructing small (\2 m) to medium-diameter (\4 m) tunnels. Uncertainties and construction difficulties increase significantly when the diameter of the tunnel exceeds 4 m. This paper presents a case study of the largest concrete pipe-jacking tunnel project in the world, the...

Biogas productivity of anaerobic digestion process is governed by a core bacterial microbiota

Anaerobic digestion (AD) has been commercially operated worldwide in full scale as a resource recovery technology underpinning a circular economy. However, problems such as a long start-up time, or system instability, have been reported in response to operational shocks. These issues are usually linked to the dynamics of the functional...

Life cycle assessment in wastewater treatment:: Influence of site-oriented normalization factors, life cycle impact assessment methods, and weighting methods

This present study aims to analyze the differences in results of different site-directional life cycle assessment<br/>(LCA) methods applied in the field of wastewater treatment. Site-generic methods were employed and<br/>compared with China-specific methods on a full-scale wastewater treatment case. A set of Chinese<br/>normalized factors were...

Potential impact of methyl isobutyl ketone (MIBK) on phenols degradation in an UASB reactor and its degradation properties

Methyl isobutyl ketone (MIBK) as a solvent is extensively used for the phenols extraction from the wastewater, so it is unavoidable to expose in the effluent due to the solubility and leakage problem. The present study evaluated the impact of MIBK on phenols degradation in an UASB reactor and analyzed its degradation properties. The results...
