In this paper, we construct an efficient decoupling-type strategy for solving the Allen-Cahn equation on curved surfaces. It is based on an FEM-EIEQ(Finite Element Method and explicit-Invariant Energy Quadratization) fully discrete scheme with unconditional energy stability. Spatially the FEM is adopted, using a triangular mesh discretization strategy that can be adapted to complex regions. Temporally, the EIEQ approach is considered, which not only linearizes the nonlinear potential but also gives a new variable that we combine with the nonlocal splitting method to achieve the fully decoupled computation. The strategy can successfully transform the Allen-Cahn system into some completely independent algebraic equations and linear elliptic equations with constant coefficients, we only need to solve these simple equations at each time step. Moreover, we conducted some numerical experiments to demonstrate the effectiveness of the strategy.

Surgical robots are designed to provide enhanced precision and dexterity compared to manual surgical procedures,which mainly rely on multimodal sensing technologies for the surgeon to seamlessly operate the robotic arms and *** with single-mode sensors, optical and mechanical bi-modal sensors provide improved precision, enhanced safety,and robustness of human-machine interaction systems. Here, the template-guided and pneumatic printing technologies are combined to construct perovskite and graphene parallel structures with both optical and mechanical sensing capabilities. The printed uniformly crystallized perovskite microstructure exhibits fast and sensitive photoelectric response characteristics,enabling shadow recognition functionality. The combination of graphene and elastic rubber endows the great printability to prepare parallel structures near the perovskite arrays for force sensing capabilities. Thus, the printed perovskite and graphene structures possess non-contact optical sensing capabilities to detect hand position by recognizing shadows between the hand and the sensor, as well as contact mechanical sensing capabilities to detect touch force applied by the hand. It provides a synergistic platform for real-time and multidimensional feedback to improve human-machine interaction.

17-Estradiol (E2) is a natural steroidal estrogen essential for a variety of physiological functions in organisms. However, external E2, which is renowned for its potent biological effects, is also considered to be an endocrine-disrupting compound (EDC) capable of disturbing the normal operation of the endocrine system, even at nanogram-per-liter (ng/L) concentrations. Studies have revealed that medical and livestock wastewater can be contaminated with E2, which poses potential risks to human health. Currently, the primary method for detecting E2 relies on liquid chromatography-mass spectrometry, which is limited with regard to on-site or large-scale sample testing due to instrumental constraints. Herein, we developed a magnetic graphene oxide (MGO)/aptamer separating material. The MGO was synthesized by creating a water-in-oil microemulsion at 90 ℃, an agarose hydrogel to load the FeO nanoparticles, and layered graphene oxide (GO). In contrast to conventional methods, such as chemical co-precipitation and solvothermal approaches, this method is more time-efficient and does not require high temperature or pressure. Moreover, the use of a physical encapsulation technique for enwrapping the FeO nanoparticles and layered GO eliminates the need for chemical modification. This approach reduces the use of harmful chemicals, ensures complete loading, and results in highly efficient encapsulation. The MGO was characterized using Fourier-transform infrared (FT-IR) spectroscopy and transmission electron microscopy (TEM), as well as dynamic light scattering (DLS) and Zeta potential analyses, which revealed that the FeO nanoparticles had been successfully loaded onto the GO to produce MGO particles mainly around 5 μm in size. Additionally, this study demonstrated that the aqueous MGO dispersion is highly stable. This substance was used to develop a fluorescent biosensor that uses a "turn-on" mechanism to rapidly and highly sensitively detect E2. MGO is capable of adsorbing a fl

Dear Editor, Liver transplantation(LT) is the only curative therapy for patients with endstage liver disease(He et al., 2023; Ling et al., 2022). Post-transplant hypertriglyceridemia(PTHT), which has an incidence of up to 32.8% in 6 months after LT, is one of the major post-transplant complications(Toshima et al., 2020).

发展新质生产力是中共二十届三中全会的重要议题之一,是推动经济高质量发展的关键。新质生产力的本源概念产生于社会转型时期现实问题的需要,经过“酝酿、出场、应用”三个阶段的动态演进,展现出强烈的实践性和时代性。培育新质生产力的关键机理在于以科技创新引领产业创新、以技术创新推动技术应用,构成“劳动者+基础创新+应用创新”的三维实践理路。广阔的国土空间决定了发展新质生产力具体路径的多元性,有必要从抽象走向具体,考察相对微观层面的经验做法。基于新疆尉犁的案例分析表明,推动农业农村领域的新质生产力发展,可以通过数智技术、生物技术来革新农业劳动资料,通过激活乡村土地资源、文化资源、数据资源和生态资源来拓展劳动对象,积极培育和引进优质个体劳动者与协作劳动组织,充分发挥区域资源禀赋。

产品自损是否属于产品责任的赔偿范围，立法、司法和理论界各有不同的看法。基于产品瑕疵的产品自损和基于产品缺陷造成他人损害的损害赔偿责任，在责任性质、构成要件、责任形态等方面各有不同。在传统民法体系中，前者属于合同法中的瑕疵担保责任，后者属于侵权法中的无过错产品责任，具有明确的区分。《侵权编解释》第19条特别规定将产品自损纳入产品责任的赔偿范围，突破了传统民法理论中合同责任和侵权责任的界分。为了避免体系内部的规范冲突，在实践中需要特别注意，在适用范围上，明确只有缺陷导致的产品自损才能通过侵权责任救济。在赔偿范围上，部分的履行利益能够纳入侵权责任的保护范围。在免责事由上，瑕疵检验期间并不能成为不承担侵权责任的理由。
