Summary: Organic polymer materials have attracted attention in various fields due to their natural abundance, economic efficiency, and easy design of molecular structure. However, their low fire safety has hindered their applications. A novel phosphorus-rich and nitrogen-rich organic polymer material, MAPA, was prepared for the first time in this study, exhibiting excellent performance as an anode for lithium-ion batteries. Additionally, the flame-retardant properties of MAPA in different electrolytes show promising potential for practical applications.

Summary: The purpose of this study was to investigate whether superficial peroneal nerve stimulation (SPNS) could improve nonobstructive urinary retention (NOUR) induced by prolonged pudendal nerve stimulation (PNS). The study found that continuous or intermittent application of SPNS significantly increased voiding efficiency and reduced postvoid residual volume. Furthermore, noninvasive SPNS applied by skin surface electrodes also improved NOUR. This study suggests that abnormal pudendal afferent activity may be a pathophysiological cause of NOUR in patients with Fowler's syndrome.

Summary: This study investigates the impact of temperature on nerve conduction block induced by high-frequency (kHz) stimulation. Results show that at a lower temperature of 15 degrees C, both 2- and 10-kHz stimulations caused an initial muscle contraction followed by nerve block. The threshold for acute block was significantly higher for 10 kHz compared to 2 kHz. However, at a higher temperature of 20 degrees C, the threshold for acute block with 10-kHz stimulation decreased, while 2-kHz stimulation induced a tonic muscle contraction and a poststimulation block.

However, due to limited data, understanding the patterns and causes of these floods has been challenging. This study uses dendrogeomorphology to reconstruct flash flood history in the Qilian Mountains and identifies precipitation in August and September as a key factor driving these floods. The findings provide important information for climate change response and flood prevention in the region.

Summary: This paper proposes a three-way decisions method based on aggregation operators of strict t-norms and t-conorms under double hierarchy linguistic environment to overcome the challenge of decision making in a complex linguistic environment. The paper introduces strict t-norms and t-conorms to define operation rules and proposes the double hierarchy linguistic weighted average (DHLWA) operator and weighted geometric (DHLWG) operator. The paper also incorporates the computational model of expected loss and the Bayesian minimum-loss decision rules in constructing the three-way decisions model.

Summary: This paper uses uncertainty theory, uncertain programming, and network optimization theory to solve uncertain network optimization problems. It redefines the concept of an uncertain network system based on uncertainty theory and uncertainty graph, and proposes a unified identification method using a conditional uncertain measure matrix. A network optimization model for the shortest path problem based on a conditional uncertain measure matrix is then established. A hybrid intelligent algorithm is designed using measure simulation technology to solve the model. The correctness and feasibility of the approach are illustrated using a numerical example of an underground logistics system.
