As the backbone of national strategic development, Complex Product Systems (CoPS) have made great achievements in China, the world’s largest demand market and second largest economy. However, their further development is challenged by the dynamic environment, including the ongoing Sino-US trade friction, for example. The aim of this research is to investigate the influence of the dynamic external environment on CoPS innovation. Based on contingency theory, this study identifies and investigates the moderating effects of technological and market dynamism on the relationship between the integrator’s coordination and its technological innovation performance. Using survey data from 209 CoPS integrator enterprises in China, the findings show that (1) the positive effect of an integrator’s coordination on technological innovation performance is strengthened by technological dynamism, while (2) weakened by market dynamism. In addition, (3) the technological dynamism acts as a higher-order moderating role in inhibiting the negative moderating effect of market dynamism on the main effect in general. Furthermore, (4) an unexpected but inspiring finding shows that the integrator’s coordination facilitates innovation most when both the technology and market dimensions are highly dynamic. This study may indicate that managerial recognition may have significant influence on enterprise’s behavior.

Aims: This study aimed to evaluate the association between stress hyperglycemia ratio (SHR) and clinical outcomes at 90 days in acute ischemic stroke due to large vessel occlusion receiving endovascular treatment. Methods:The RESCUE BT trial was a multicenter, randomized, double-blind, placebocontrolled clinical trial, consisting of 948 stroke patients from 55 centers in China. A total of 542 patients with glucose and glycated hemoglobin (HbA1C) values at admission were included in this analysis. SHR, measured by glucose/HbA1C, was evaluated as both a tri-categorical variable (≤1.07 vs. 1.08-1.29 vs. ≥1.30) and a continuous variable. The primary outcome was a favorable functional outcome (modified Rankin Scale [mRS] score ≤2) at 90 days. The secondary outcome included excellent functional outcome (mRS score ≤1) and safety outcomes, such as 90-day mortality and intracranial hemorrhage. The study was registered with Chictr.org.cn (ChiCTR-INR-17014167).Results: Compared with patients in the lowest tertile of SHR, the highest tertile group had significantly lower odds of achieving favorable functional outcome of mRS score of 0-2 (adjusted odds ratio, 0.44; 95% confidence interval, 0.28-0.69; p < 0.001) and excellent clinical outcome of mRS score of 0-1 (adjusted odds ratio, 0.48; 95% confidence interval, 0.29-0.79; p = 0.004) at 90 days after adjusting for potential covariates. Similar results were observed after further adjustment for preexisting diabetes and Alberta Stroke Program Early Computed Tomography Score (ASPECTS). Conclusion:Stress hyperglycemia ratio, as measured by the glucose/HbA1C, was associated with a decreased odds of achieving a favorable functional outcome in patients with acute large vessel occlusion stroke at 90 days.

An air cooling battery thermal management system (BTMS) is widely used in electric vehicles (EVs). In this work, numerical simulation is used to provide a greater understanding of the system efficiency of T-type symmetric air cooling BTMS (T-BTMS) and its coupled systems. For T-BTMS, the method of the coefficient of variation (MCV) is applied to evaluate the schemes with different inlet flow rates and battery clearances. It is found that optimum cooling performance and energy consumption are achieved at an internal clearance of 3 mm and an inlet air velocity of 6 m•s −1 . Further improvements in cooling performance can be realized by introducing heat transfer fins into the module. Increasing the number of fins can improve cooling performance but results in higher energy consumption. To further improve the cooling performance at high battery discharge rates, a coupled system with air cooling and liquid cooling is proposed. It is found that, at high discharge rates, the coupled system gives better cooling performance and lower energy consumption compared to uncoupled systems. When the battery module is fully discharged at the rate of 4 C, the maximum temperature of the coupled system is below the critical value of 45 °C and the maximum temperature difference is less than 5 °C.
