A novel compressive optical cryptosystem based on single-pixel imaging is proposed. By using random sparse sampling in the encryption process, the plaintext is encrypted and compressed into a noise-like intensity sequence. As a result, the ciphertext is much less than the plaintext in volume. For de...

Modal estimation of aberration can quantify the amount of aberration, which plays an important role in optical system optimization, aberration correction, and so on. Here, we propose a simple but effective method to find the modal wavefront of aberration. Once the aberrated wavefront has been detect...

This study used integrated in vitro and in vivo approaches to investigate how the starch source (glutinous rice, indica rice, maize, or high-amylose rice) influences starch digestion kinetics and, consequently, the apparent nutrient utilization and amino acid metabolism in goslings. Four diets were...

The monosodium glutamate wastewater is acidic, which is not suitable to be nitrified directly. Therefore, some chemicals need to be added to neutralize it. Among the four tested neutralization chemicals, lime and sodium hydroxide are better to adjust pH than sodium carbonate and sodium bicarbonate....

Nitrification is an effective technology to control nitrogen pollution from wastewater. The effect of pH on nitrification and the relationship between pH and alkalinity were analyzed. It was shown that pH exerted not only a large influence on the growth and metabolism of nitrifying bacteria but also...

To explore the mechanical characteristics and progressive failure characteristics of jointed gypsum rock under quasi-static loading, uniaxial compression tests were carried out on gypsum rocks with various joint angles. Using acoustic emission (AE) and digital image correlation (DIC) techniques, the...

This study assessed the effects of antifreeze peptides (CsAFPs) produced by enzymatical hydrolysis of chicken skin on chicken mince stability. CsAFPs, 85.88% of which were short peptides (180–3 000 Da), showed high hydrophilicity and strong thermal hysteresis activity and ice recrystallization inhib...
