Article Abstract
Given the complex powertrain of fuel cell electric vehicles (FCEVs) and diversified vehicle platooning synergy constraints, a control strategy that simultaneously considers inter-vehicle synergy control and energy economy is one of the key technologies to improve transportation efficiency and release the energy-saving potential of platooning vehicles. In this paper, an energy-oriented hybrid cooperative adaptive cruise control (eHCACC) strategy is proposed for an FCEV platoon, aiming to enhance energy-saving potential while ensuring stable car-following performance. The eHCACC employs a hybrid cooperative control architecture, consisting of a top-level centralized controller (TCC) and bottom-level distributed controllers (BDCs). The TCC integrates an eco-driving CACC (eCACC) strategy based on the minimum principle and random forest, which generates optimal reference velocity datasets by aligning the comprehensive control objectives of the platoon and addressing the car-following performance and economic efficiency of the platoon. Concurrently, to further unleash energy-saving potential, the BDCs utilize the equivalent consumption minimization strategy (ECMS) to determine optimal powertrain control inputs by combining the reference datasets with detailed optimization information and system states of the powertrain components. A series of simulation evaluations highlight the improved car-following stability and energy efficiency of the FCEV platoon.

Although cold atmospheric plasma is a promising therapeutic technique for tumor immunotherapy via reactive oxygen and nitrogen species (RONS), the challenges associated with the generation and delivery of these RONS hamper clinical adoption. Herein, a dual-mode hybrid discharge plasma-activated sodium alginate hydrosols (PAH) is proposed to enhance the antitumor immune response. Gaseous highly reactive RONS are generated by dual-mode hybrid plasma produced by mixed O and NO modes, which are converted into aqueous RONS in PAH via gas-liquid reactions between plasma and hydrosols.

The duplex-forming behavior of an inchworm-type PNA-PEG conjugate (i-PPc), engineered for the selective recognition of point mutations in DNA, was assessed through thermodynamic analysis employing UV melting curves and circular dichroism spectroscopy. The i-PPc demonstrated the ability to form stable duplexes exclusively with fully complementary DNA sequences, while no hybridization with single-base mismatched sequences. This binary on/off hybridization behavior was maintained even under physiologically relevant conditions (37 °C), thereby illustrating the exceptional point mutation discrimination capability of i-PPc.

Facing the massive energy consumption of over 200 TWh y of chlor-alkali industry, developing high-activity and durable non-precious CER (chlorine evolution reaction) catalysts is urgently needed to address the high overpotentials and suppress the dissolution high-valance metal species. Herein, a carbon quantum dots functionalized trimetallic Fe/Co/Ni spinel oxide nanotube architecture (FCNO@CQDs) is constructed, featuring t-to-π* π-backbonding for dramatically enhanced CER activity and stability. The reverse electron flow from Co d-obritals to the vacant CQDs' π* orbitals can upshift the d-band center for enhanced intermediate adsorption, while stabilizing high-valent Co centers via increased bond order.

The processing-transportation composite robots, with their dual functions of processing and transportation, as well as comprehensive robot-machine interactions, have been widely and efficiently applied in the manufacturing industry, leading to a continuous increase in energy consumption. Hence, this work focuses on investigating robot-machine integrated energy-efficient scheduling in flexible job shop environments. To address the new problem, an innovative mixed-integer linear programming model and a novel dual-self-learning co-evolutionary algorithm are proposed, aimed at minimizing the total energy consumption and makespan.

Background: Chronic rejection is a major cause of long-term kidney allograft failure, characterized by persistent inflammation and progressive fibrosis. Macrophages are central mediators of this process, but their phenotypic heterogeneity and regulatory mechanisms in chronic rejection remain incompletely understood.
Methods: We performed single-cell transcriptomic analysis on renal allograft biopsies from patients with different types of rejection and on a time-course rat model of chronic rejection.
