Summary: In order to investigate how the digital transformation of port firms improves their operational resilience, we designed methods to measure their digital transformation grade (DTG), technological innovation capacity (TIC), and port operational resilience (POR) respectively. Based on 3586 samples retrieved from 334 Chinese port firms from 2011 to 2021, their relationships were statistically described and preliminarily regressed by an ordinary least squares model and a fixed-effect model. After testing the effects of supply chain disruption, endogeneity, and robustness, it was revealed that digital transformation improves firms' competitiveness and operational resilience by coordinating human resources, information, and technology. It was confirmed that TIC plays an intermediate role and adverse events have an enhancement effect. An inverted-U curve between DTG and POR proves that port firms often suffer growing pains at the initial stage and their POR will be promoted by continuous digital inputs, but the leading port firms would gain fewer marginal benefits.

Summary: Bioelectrochemical systems (BES) have a wide range of applications in the environmental field, but there is limited research on scaling up these systems. A pilot-scale microbial electrolysis cell (MEC) was operated for six months under various operational conditions to understand the limiting factors of hydrogen production. The use of synthetic wastewater yielded the maximum current density and hydrogen production, while low COD urban wastewater limited plant performance. The study also showed that the MEC pilot plant had a robust capacity to remove organic matter from wastewater.

Summary: This study investigated the relationship between the severity in the grading of microvascular invasion (MVI) and long-term oncological outcomes in patients with early-stage hepatocellular carcinoma (HCC). The results showed that the severity in MVI grading was independently associated with recurrence and survival after HCC resection. Patients with a more severe MVI grading (M2) require more stringent recurrence surveillance and/or active adjuvant therapy against recurrence.
