Cracking caused by aging or repeated bending can severely affect the lifetime of electrochromic devices. In this work, a self‐healing electrochromic hydrogel was developed with poly (vinyl alcohol) (PVA)‐sodium carboxymethyl chitosan (SCC) semi‐inter transfer network as the matrix, viologen bromide (HPV2+2Br−) as the electrochromic substance, and borax as the cross‐linking agent. The self‐healing properties of hydrogel stem from the dynamic and reversible borate bonds between borax and PVA molecular chains. As the voltage changes, the color of the device transitions from colorless to light purple and then to dark purple. The optical contrast at 600 nm reaches approximately 51 %. At room temperature, the disconnected hydrogel can fully restore its original state after 30 minutes of contact, effectively addressing issues related to cracks and damage in flexible electrochromic devices. This research holds significant implications for enhancing the reliability and stability of flexible electrochromic devices. [ABSTRACT FROM AUTHOR]

Background: Currently, there is a lack of effective indicators for predicting the efficacy of immunotherapy in patients with advanced hepatocellular carcinoma (HCC). This study aimed to investigate the expression and prognostic value of peripheral T lymphocyte subsets in advanced HCC. Methods: Patients with advanced HCC who were treated with immune checkpoint inhibitors (ICIs) from December 2021 to December 2023 were included in the study. Flow cytometry was used to detect lymphocyte subsets before treatment. The patients were divided into disease control (DC) and nondisease control (nDC) groups based on treatment efficacy. Relationships between the clinical characteristics/peripheral T lymphocytes and immunotherapy efficacy were analyzed. The effectiveness of peripheral T lymphocyte subsets in predicting immunotherapy efficacy for patients with advanced HCC was analyzed using receiver operating characteristic (ROC) curves. Results: A total of 40 eligible patients were included in this study. Non-DC was significantly associated with higher albumin-bilirubin (ALBI) scores. The percentages of γδ+Vδ2+PD1+ T cells and γδ+Vδ2+Tim3+ T cells were greater in the nDC group than in the DC group. Multivariable regression analysis revealed that the ALBI score and T lymphocytes expressing γδ+Vδ2+PD1+ and γδ+Vδ2+Tim3+ were founded to be independent influencing factors. The area under the ROC curve (AUC) values for these combinations was 0.944 (95% CI, 0.882 ~ 1.000). Conclusions: The calculation of the ALBI score and determination of the percentages CD3+γδ+Vδ2+PD1+ T lymphocytes and CD3+γδ+Vδ2+Tim3+ T lymphocytes in the peripheral blood of patients with advanced HCC are helpful for predicting the patients’ responses to ICIs, helping to screen patients who may clinically benefit from immunotherapy.

Fiber-shaped supercapacitors with high energy density have been an active subject of research due to their promising prospect for use in portable and wearable electronics. Herein, we report on a robust two-step strategy for crafting a MgS nanowire-draped NiCo2S4 nanosheet network (i.e., NiCo2S4@MgS nanocomposites) in situ grown on ultrafine flexible stainless steel microwires to render knittable supercapacitors with markedly enhanced performance. The two-step route involves the formation of oxide compounds, followed by their conversion into NiCo2S4@MgS nanocomposites. In sharp contrast to pure NiCo2S4 nanosheets, NiCo2S4@MgS nanocomposites facilitate a rapid charge transport between NiCo2S4 nanosheets and MgS nanowires due to the presence of the interconnected MgS network and manifest a more than two-fold discharging time over that of NiCo2S4. Notably, fiber-shaped asymmetric supercapacitors (denoted as FASCs), assembled by intertwining a NiCo2S4@MgS positive electrode and a FeOOH negative electrode electrodeposited on the same type of stainless steel microwires, deliver a remarkable specific volumetric capacity of 134.4 mA h cm−3, a high energy density of 107.5 mW h cm−3, and a good power density of 1.7 W cm−3 at 1 mA cm−2. More importantly, the FASCs also demonstrate great stability with 87.5% performance retention after 5000 cycles. Such hair-like FASCs enable the successful charging of an electronic bracelet, and can power light-emitting diodes (LEDs) after being woven into fabrics. As such, the two-step strategy in this study may represent a viable means of yielding a variety of metal-containing oxide, sulfide, and nitride networks on stainless steel microhairs for high-performance and light-weight wearable electronics.

Yang, X.; Zhao, N.; Bian, Z.; Chai, J., and Mi, C., 2015. An intelligent storage determining method for inbound containers in container terminals. In this paper, the container Stacking Position Determination Problem (SPDP) for inbound containers in the process of vessel loading and unloading activities is discussed, specifically focusing on the storage space allocation problem (SSAP) in container terminals. The process of positioning inbound containers is investigated and analyzed based on an advanced handling strategy, namely assigning quay cranes in their full utilization with the aim of 'Full In & Full Out' that is proposed for internal trucks, where intense loading and unloading activities are considered at the same time. A multi-objective integer programming model (MOIPM) is then put forward based on the idea of real-time strategic planning. For the solution, a genetic algorithm (GA) is employed to address the formulated problem. In addition to the effectiveness and reliability of the proposed model, a number of experimental results also verify the robustness of the GA algorithm. The application of the proposed method is able to improve operational efficiency in container terminals and reduce handling costs as well. [ABSTRACT FROM AUTHOR]
