This study investigates the dynamic response, damage mechanisms and strategies for enhancing the resistance of reinforced concrete-steel liner (RC-SL) composite structures subjected to tube-type missile impacts. Experimental tests were conducted on eight RC-SL specimens with varying configurations u...

This paper proposes and demonstrates a novel coded amplitude and pulse position modulation (APPM) scheme based on 2-D cyclic iterative coding (TDCIC) for short-reach optical systems. By adopting the precoding, better performance can be obtained because of the bits correlation. An experiment with 150...

We propose and experimentally demonstrate the generation of a multiple-frequency optical millimeter-wave (mm-wave) signal an without optical filter at the transmitter side. Forty, 80, and 120-GHz multiple-frequency optical mm-wave signals are generated simultaneously in our experiment. After 20&...

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare acquired disorder of intravascular hemolysis caused by a somatic mutation in the gene responsible for glycosylphosphatidylinositol (GPI)-anchored complement regulatory proteins. This mutation leads to the production of abnormal blood cell clones la...

Numerous tests have demonstrated the impact of microbiologically influenced stress corrosion (MISC) on oil and gas pipelines, but the dynamic corrosion process and its influencing variables remain unclear. In this paper, through material and environment data collection, we analyzed the important fac...

The utilization of orbital angular momentum (OAM) in light for information encoding is a promising avenue, as it exhibits resilience against environmental disturbances. However, the direct detection of OAM poses a significant challenge due to beam distortion during transmission, which ultimately lim...

Study region: The Middle Yellow River Basin (MYRB) Study focus: Environment changes, including human activities (i.e., underlying surface changes) and climate change, have significantly influenced evapotranspiration (ET) processes. However, in the MYRB, research on how ET and its components respond...

Objective: The present study aims to determine the causal association between sodium-glucose cotransporter inhibitors and depression, as previous observational studies have concluded a potential link between sodium-glucose cotransporter 1/2 inhibition and depression. Methods: A total of 16 instrumen...

Hepatitis E virus (HEV) has become one of the important pathogens that threaten the global public health. Type 3 and 4 HEV are zoonotic, which can spread vertically and cause placental damage. At the same time, autophagy plays an important role in the process of embryo development and pregnancy main...

In contrast to terrestrial networks, the rapid movement of low-earth-orbit (LEO) satellites causes frequent changes in the topology of intersatellite links (ISLs), resulting in dynamic shifts in transmission paths and fluctuations in multi-hop latency. Moreover, limited onboard resources such as buf...

The machine learning method for surrogate modeling is a keystone in surrogate model-assisted evolutionary algorithms (SAEAs). The current arguably most widely used surrogate modeling methods in SAEAs are Gaussian process and radial basis function. This paper investigates the behavior of a machine le...

We propose an effective scheme to enhance the efficiency of optical second-order sideband (OSS) via optomechanically induced absorption (OMIA) in a double-cavity optomechanical system. In this double-cavity optomechanical configuration, the optomechanical cavity is driven by a strong control field a...

Molybdenum tailings (MT) are solid wastes discharged from molybdenum mines after mining and sorting. At present, accumulation is still the primary treatment method of MT, which causes great harm to the environment. If MT can be used to prepare cement concrete pavement for low-grade roads, its utiliz...
