- Boundary-to-Solution Mapping for Groundwater Flows in a Toth Basin. (arXiv:2303.... In this paper, the authors propose a new approach to solving the groundwater flow equation in the Toth basin of arbitrary top and bottom topographies using deep learning. Instead of using traditional numerical solvers, they use a DeepONet to produce the boundary-to-solution mapping. This mapping takes the geometry of the...
- Photo-strobo-acoustic Imaging at the Microscale by Laser-Induced Ultrasound. (ar... The combination of microfluidic technology and optical fluids characterization techniques has been recently applied to produce lab-on-a-chip systems. In the present work, bringing together the imaging technique called photoacoustic imaging (PAI) and microfluidic technology were implemented to obtain micro-scale imaging. Laser-induced ultrasound signals were measured from microdroplets produced in a...
- Experimental determination of the energy dependence of the rate of the muon tran... We report the first experimental determination of the collision-energy dependence of the muon transfer rate from the ground state of muonic hydrogen to oxygen at near-thermal energies. A sharp increase by nearly an order of magnitude in the energy range 0 - 70 meV was found that is not observed...
- Planning for Electric Vehicles Coupled with Urban Mobility. (arXiv:2303.15578v1... The rising adoption of plug-in electric vehicles (PEVs) leads to the alignment of their electricity and their mobility demands. Therefore, transportation and power infrastructures are becoming increasingly interdependent. In this work, we uncover patterns of PEV mobility by integrating for the first time two unique data sets: (i) mobile phone...
- Dynamical Behaviors of Small-scale Buoyant Diffusion Flame Oscillators in Extern... Small-scale flickering buoyant diffusion flames in externally swirling flows were computationally investigated with a particular interest in identifying and characterizing various distinct dynamical behaviors of the flame oscillators under different swirling flow conditions. By varying the external swirl, six distinct flame dynamical modes, such as the flickering flame, the oscillating...
- Transverse flow under oscillating stimulation in helical square ducts with cochl... The cochlea is our fluid-filled organ of hearing with a unique spiral shape. The physiological role of this shape remains unclear. Previous research has paid only little attention to the occurrence of transverse flow in the cochlea, in particular in relation to the cochlea's shape. To better understand its influence...
- Phase-field Simulations of Polarization Variations in Polycrystalline Hf0.5Zr0.5... In this work, we investigate the device-to-device variations in remanent polarization of Hafnium-Zirconium-Oxide based Metal-Ferroelectric-Insulator-Metal (MFIM) stacks. We consider the effects of polycrystallinity in conjunction with multi-domain effects in HZO to understand the dependencies of variations on static and dynamic voltage stimuli using our 3D dynamic multi-grain phase-field simulation framework....
- Deconstructing Human Capital to Construct Hierarchical Nestedness. (arXiv:2303.1... Modern economies generate immensely diverse complex goods and services by coordinating efforts and know-how of people in vast networks that span across the globe. This increasing complexity puts us under the pressure of acquiring an ever-increasing specialized and yet diverse skill portfolio in order to stay effective members of a...
- Thermal Emission Control via Twist Tuning of Embedded Eigenstates. (arXiv:2303.1... The field of thermal emission engineering shows great potential for various applications, such as lighting, energy harvesting, and imaging, using natural or artificial structures. However, existing structures face challenges in fabrication or do not provide the necessary degree of control over key parameters such as emission intensity, spectral composition, and...
- 7.86 kV GaN-on-GaN PN Power Diode with BaTiO3 for Electrical Field Management. (... Device based on GaN have great potential for high power switching applications due to its high breakdown field and high electron mobility. In this work, we present the device design of a vertical GaN-on-GaN PN power diode using high dielectric constant (high-k) dielectrics for electrical field management and high breakdown...
- Strong chiral optical force for small chiral molecules based on electric-dipole... Drawing inspiration from a remarkable chiral force found in nature, we show that a static electric field combined with an optical lin$perp$lin polarization standing wave can exert a chiral optical force on a small chiral molecule that is several orders of magnitude stronger than other chiral optical forces proposed to...
- Linking Unserved Energy to Weather Regimes. (arXiv:2303.15492v1 [physics.soc-ph]... The integration of renewable energy sources into power systems is expected to increase significantly in the coming decades. This can result in critical situations related to the strong variability in space and time of weather patterns. During these critical situations the power system experiences a structural shortage of energy across...
