1. IntroductionIn recent years, China has witnessed a rising level of urbanization, accompanied by an escalating demand for land resources. During project construction, particularly in the processes of pit excavation and river maintenance, substantial amounts of silt waste are generated. Curing treatment of this waste silt can notably enhance its bearing capacity and facilitate its effective utilization [1].

2. Contents of Dynamic Load Test 2.1. Project OverviewThis project intersects with the Ji-Hei Expressway, which is currently under construction near Fuxing Village in Changbao Town, north of Wuchang City. The B ramp bridge consists of two unequal-span steel box girders. The first span of the bridge is 48 m long, the second span is 34 m long, and the total width of the bridge is 10.5 m, with two one-way lanes. The bridge layout is shown in Figure 1.

1. IntroductionWith the breakthrough of China’s bridge construction technology and the need for rapid economic development, China’s bridge construction has gradually changed from “reconstruction and light maintenance” to “construction and maintenance”. Bridge technical condition assessment is an important basis for bridge maintenance work. Bridge maintenance personnel will make corresponding maintenance decisions for different technical condition levels.

AbstractHydrogen sulfide (H2S) is an important endogenous gasotransmitter, but the bioorthogonal reaction triggered H2S donors are still rare. Here we show one type of bioorthogonal H2S donors, sydnthiones (1,2,3-oxadiazol-3-ium-5-thiolate derivatives), which was designed with the aid of density functional theory (DFT) calculations. The reactions between sydnthiones and strained alkynes provide a platform for controllable, tunable and mitochondria-targeted release of H2S.

1. IntroductionAs bridge infrastructure ages, traditional inspection methods like visual inspection and inspection vehicles have become increasingly inadequate. These methods are time-consuming and costly and pose safety risks, making them insufficient for efficient and precise assessments. In recent years, new technologies such as drones and LiDAR have emerged in bridge inspection. However, these methods still face challenges like blind spots and complex equipment.

1 INTRODUCTION Since the development of the capital asset pricing model (Sharpe, 1964), modern finance theory has asserted that the cross-sectional variation in stock returns is attributable to differences in how stocks load on risk factors. Alas, nearly 60 years later, risk factors that are grounded in theory, well defined and readily observable remain elusive.
