Quantitative Properties on the Steady States to A Schr\"odinger-Poisson-Slater System
A relatively complete picture on the steady states of the following
Schrdinger-Poisson-Slater (SPS) system \begin{cases} -\Delta
Q+Q=VQ-C_{S}Q^{2}, & Q>0\text{ in }\mathbb{R}^{3}\\ Q(x)\to0, & \mbox{as
}x\to\infty,\\ -\Delta V=Q^{2}, & \text{in }\mathbb{R}^{3}\\ V(x)\to0 &
\mbox{as }x\to\infty. \end{cases}
is given in this paper: existence, uniqueness, regularity and asymptotic
behavior at infinity, where is a constant. To the author's knowledge,
this is the first uniqueness result on SPS system

Deep Learning Convective Flow Using Conditional Generative Adversarial Networks
We developed a general deep learning framework, FluidGAN, that is capable of
learning and predicting time-dependent convective flow coupled with energy
transport. FluidGAN is thoroughly data-driven with high speed and accuracy and
satisfies the physics of fluid without any prior knowledge of underlying fluid
and energy transport physics. FluidGAN also learns the coupling between
velocity, pressure and temperature fields. Our framework could be used to learn
deterministic multiphysics phenomena where the underlying physical model is
complex or unknown
Electrolysis-based Parylene Balloon Actuators for Movable Neural Probes
In order to track a specific neuron and keep good sampling neural signals during chronic implantation, the neural probes are highly desired to have moving capability. This paper presents a novel electrolysis-based parylene balloon actuator fabricated with MEMS technology. The actuator is integrated with silicon probe to make it movable. A new fabrication technology has been developed to build a parylene balloon structure with silicon spring structure, electrolysis electrodes and electrolyte inside. By applying little current to electrolysis electrodes, high pressure is generated inside the parylene balloon by electrolysis. The spring structure is stretched with the parylene balloon expansion. Therefore the neural probe is moved by the actuation. The electrolysis actuator can generate large stain and pressure, requires modest electrical power and produces minimal heat. Due to the large volume expansion obtained via electrolysis, the small actuator can create a large force. The new electrolysis actuators for movable neural probes have been fabricated and validated
CO preferential oxidation in a novel Au@ZrO₂ flow-through catalytic membrane reactor with high stability and efficiency
CO preferential oxidation (CO-PROX) achieves much interest as a strategy to remove trace CO in reformed gases for hydrogen utilization. Herein, we reported a novel Au@ZrO₂ catalytic membrane reactor by embedding gold nano-particles in ZrO₂ hollow fiber membrane for CO-PROX. The flow-through catalytic membrane exhibited high catalytic activity and oxygen selectivity, which gave a turnover frequency of 4.73 s⁻¹ at 60 °C, 2–3 times higher than conventional catalyst pellets. CO conversion of >95% was achieved over the catalytic membrane, which maintained great operational stability during 500-h operation even CO₂ and H₂O were added in the feed stream. The excellent catalytic performance of the flow-through catalytic membrane makes gold catalyst possible for practical application in the removal of CO from hydrogen
