CSEE Journal of Power and Energy Systems 2024年第2期10卷 686-695页

For modular multilevel converter-based battery energy storage systems (MMC-BESS), uneven power among batteries of SMs will be deduced by battery aging, battery fault, etc., which will degrade performance and even lead to system failure. For maintaining the balance of capacitor voltage, this paper analyzes the limits of the uneven power of batteries, which are presented as the current limits in this paper. According to analysis, an analytical method is proposed that only the dc and fundamental frequency components of the arm current are used to calculate current limits. With the current limits it is able to evaluate the reasonability of power distribution among batteries. Meanwhile, increase of fundamental frequency component will enhance the current limits, and the dc component determines the size relationship between the absolute values of the upper and lower current limits. Finally, simulation model and experiment prototype are built for verifying the theoretical analysis and current limits calculation method, and satisfactory results are provided.

Several studies have reported that C-reactive protein （CRP）, an inflammation biomarker, may be associated with the prognosis of prostate cancer （PCa）. The objective of this systematic review is to summarize the predictive role of CRP for survival in PCa as reported in previous studies. Related studies were identified, and evaluated for quality through multiple search strategies. Data was collected from studies comparing overall and cancer-specific survival （CSS） in patients with elevated CRP levels and those having lower levels. However, for progression-free survival （PFS）, data were collected according to the log of CRP. The hazard ratio （HR） and its 95% confidence interval （Cl） were used to assess the strength of associations. A total of nine studies （n = 1,497） were evaluated in this meta-analysis （five for overall survival （OS）, four for CSS and two for PFS）. For OS and PFS, the pooled HR of CRP was statistically significant at 1.51 （95% Cl, 1.28-1.79） and 1.50 （95% Cl, 1.25-1.81）, respectively. For CSS, the pooled HR was 1.91 （95% CI, 1.36-2.69） with higher CRP expression in PCa, which strongly indicates poorer survival in PCa. This study demonstrates that CRP may have a critical prognostic value in patients with prostatic cancer.

Though obstruction-free progress property is weaker than other non-blocking properties including lock-freedom and wait-freedom, it has advantages that have led to the use of obstruction-free implementations for software transactional memory (STM) and in anonymous and fault-tolerant distributed computing. However, existing work can only verify obstruction-freedom of specific data structures (e.g., STM and list-based algorithms).In this paper, to fill this gap, we propose a program logic that can formally verify obstruction-freedom of practical implementations, as well as verify linearizability, a safety property, at the same time. We also propose informal principles to extend a logic for verifying linearizability to verifying obstruction-freedom. With this approach, the existing proof for linearizability can be reused directly to construct the proof for both linearizability and ***, we have successfully applied our logic to verifying a practical obstruction-free double-ended queue implementation in the first classic paper that has proposed the definition of obstruction-freedom.

To take advantage of all the singlet and triplet excitons and then achieve 100%internal quantum efficiency in OLED devices,the scientists have proposed the thermally activated delayed fluorescence(TADF)strategy which tries to achieve"delayed"fluorescence by converting triplet excitons to singlet excitons through a reverse intersystem crossing(ISC/RISC)process with the help of thermal activation[1].In the early days,the efficient RISC processes were facilitated by a negligible energy gap(△E_(ST))and a large spin-orbit coupling(SOC)matrix element(SOCME)between the first singlet(S_(1))and triplet(T_(1))excited states.
