A quadrotor is proposed than can both fly and roll. The proposed robot employs passively reconfigurable structures to enable the rolling, tightly coupling the attitude of the robot to the rolling cage. The benefits are precise rolling and turning control as well as improved rolling efficiency. The passively reconfigurable structures are enabled by pre-stretched elastic springs to generate a nonlinear restoring torque. The robot leveraged the superior maneuverability in the rolling mode to take photos of the surroundings at different tilting and panning angles to construct a panoramic image. Besides, the results of the power measurements show a significant reduction in the cost of transport brought by at low speed, equating to a 15-fold extension in the operational range.

A novel FR-IQA paradigm involving a flexible reference selection is proposed. It dedicates to generating the reference feature by finding the best explanation of the distorted feature among an equal-quality space constructed based on a given pristine feature. Without the ground-truth reference for distorted images with various distortion types, the quality regression loss, the disturbance maximization loss and the content loss are employed to optimize the pseudo-reference feature learning. Experimental results on five IQA benchmark databases demonstrate that combining the FLRE with the existing deep feature-based FR-IQA models can gain performance improvement.

The surface of low-dimensional perovskites plays a crucial role in determining their intrinsic properties. Thus, specific surfaces may be designed to obtain a desired characteristic and/or a functional structure. Further, surface passivation could also be applied to stabilize and optimize the state-of-the-art perovskite-based optoelectronics. CsPbBr3 microwires parallel arrays with specific (100)-terminated crystal planes were designed and fabricated to have excellent photodetection performance with long-term environment stability over 3000 hours. Further, environmental oxygen may be used to passivate the Br-vacancy-related trap states on the (100) surface and to create charge carrier nanochannels to enhance the (opto)electronic properties. The coupling effects between oxygen species and the specific terminated crystal planes of perovskites highlight the importance of surface engineering for designing and optimizing perovskite-based devices.

Additionally, key genes associated with competing metabolic pathways—ldhA, frdABCD, adhE, ackA, and pta—are deleted to optimize SCFA production, particularly butyrate. This strain is intended for use in therapeutic applications where enhanced SCFA production is beneficial, such as in the treatment of coronary heart disease.

The present invention investigates the effects of hypertonicity on adipocytes, revealing its role in inducing the release of mitochondrial extracellular vesicles (MEVs). This release subsequently enhances the secretion of TNF-α, a pro-inflammatory cytokine crucial during stress responses, thereby activating the Wnt/β-catenin signaling pathway responsible for adipocyte dedifferentiation. Through the present method, hypertonicity induces MEVs release and TNF-α secretion, ultimately modulating Wnt/β-catenin signaling and promoting adipocyte dedifferentiation, offering promising therapeutic implications.

A BS sleeping strategy for a two-tier HeCN that consists of MaBS and MiBS. The approach involves strategically consolidating workloads distributed across the network onto fewer BSs. At the heart of the strategy is a Bidirectional Long Short-Term Memory (BLSTM) neural network, which predicts future traffic for each user. The predicted traffic data informs the proposed BS sleeping strategy, which shifts user connections from under-utilized MiBSs to other BSs, subsequently powering down the idle MiBSs, while MaBSs remain always on. This strategy is executed with utmost consideration for maintaining service quality, ensuring that the switch does not degrade each user's Signal-to-Interference-plus-Noise Ratio thresholds or traffic demand rate.

The obtained electrochemical cell exhibits bifunctional activity and stability (>100 h) towards reversible NO2 reduction and evolution reactions. A high cell-level energy density of 553.2 Wh·kg−1cell/1589.6 Wh·L−1cell from pouch cells (2.4 Ah) has been achieved. As an additional green feature, the produced NO2− by the Zn∥NO2 cell is subsequently converted to NH3 by a self-power mechanism, thereby servicing multiple key conversion steps in the nitrogen cycle all within a single device, paving the way to scalable, highly integrated solutions.
