Free carbene readily causes multiple side reactions due to its high energy, thus asymmetric transformation is very difficult. We present here our findings of high-pKa Brønsted acid catalysts that enable free insertion into N-H bonds amines prepare chiral α-amino derivatives with enantioselectivity. Under irradiation visible light, diazo compounds produce high-energy carbenes are captured by form ylide intermediates, and then the newly designed acids, spiro phosphamides, promote proton...
This paper proposes a lateral control strategy for autonomous vehicles (AVs) and develops an evolutionary learning framework off-ramps. Random forest (RF) back-propagation neural network (BPNN) integrated with model predictive (MPC) algorithm are respectively used to capture the decision-making trajectory characteristics during lane-changing maneuver based on Next Generation Simulation (NGSIM) dataset. Then, running cost function is calculated optimize Finally, numerical simulation conducted...
This paper proposes a trajectory tracking control method combining extended Kalman filter (EKF) and robust tube-based model predictive (RTMPC) methods to improve the anti-disturbance capability during lane-changing maneuver of automated vehicles. A time-based quintic polynomial function is introduced for implementation planning obtain desired reference trajectory. The planned input nominal system-oriented controller (MPC) in RTMPC optimization optimal system. EKF collects state measurements...

Abstract Free carbene readily causes multiple side reactions due to its high energy, thus asymmetric transformation is very difficult. We present here our findings of high‐p K a Brønsted acid catalysts that enable free insertion into N−H bonds amines prepare chiral α‐amino derivatives with enantioselectivity.

The risk of coal and gas outbursts can be predicted using a method that is linear continuous based on the initial flow in borehole (IGFB); this significantly superior to traditional point prediction method. Acquiring accurate critical values key ensuring predictions. Based ideal rock cross‐cut uncovering model, IGFB measurement device was developed. present study measured data over 3 min 1 m long with diameter 42 mm laboratory. A total 48 sets were obtained. These fuzzy chaotic. Fisher’s...
Connected automated vehicles (CAVs) rely heavily on intelligent algorithms and remote sensors. If the control center or on-board sensors are under cyber-attack due to security vulnerability of wireless communication, it can cause significant damage CAVs passengers. The primary objective this study is model cyber-attacked traffic flow evaluate impacts system filled with in a connected environment. Based analysis environmental perception possible cyber-attacks sensors, novel lane-changing for...
We propose Reference-Based Modulation (RB-Modulation), a new plug-and-play solution for training-free personalization of diffusion models. Existing approaches exhibit difficulties in (a) style extraction from reference images the absence additional or content text descriptions, (b) unwanted leakage images, and (c) effective composition content. RB-Modulation is built on novel stochastic optimal controller where descriptor encodes desired attributes through terminal cost. The resulting drift...
A textile bandwidth-enhanced half-mode substrate-integrated cavity (HMSIC) antenna based on embroidered shorting vias is designed. Based the simulated results of basic HMSIC antenna, two hollow posts with square cross-sections are added as at intersections zero-E traces TM210HM and TM020HM modes to shift TM010HM-mode band merge bands higher-order for bandwidth enhancement. prototype practically fabricated computerized embroidery techniques. Measurement show that an expanded −10 dB impedance...
Generative models transform random noise into images; their inversion aims to images back structured for recovery and editing. This paper addresses two key tasks: (i) (ii) editing of a real image using stochastic equivalents rectified flow (such as Flux). Although Diffusion Models (DMs) have recently dominated the field generative modeling images, presents faithfulness editability challenges due nonlinearities in drift diffusion. Existing state-of-the-art DM approaches rely on training...
