Engineered Biomimetic Platelet Membrane-Coated Nanoparticles Block Staphylococcus aureus Cytotoxicity and Protect Against Lethal Systemic Infection Article

Jwa-Kyung Kim, Satoshi Uchiyama, Hua Gong, Alexandra Stream, Liangfang Zhang, Victor Nizet

Engineering 2021, Volume 7, Issue 8,   Pages 1149-1156 doi: 10.1016/j.eng.2020.09.013

Abstract:

Staphylococcus (S.) aureus is a leading human pathogen capable of producing severe invasive infections such as bacteremia, sepsis, and endocarditis with high morbidity and mortality, exacerbated by the increasingly widespread antibiotic resistance exemplified by methicillin-resistant strains (MRSA). S. aureus pathogenesis is fueled by the secretion of toxins—such as the membrane-damaging pore-forming atoxin,
which have diverse cellular targets including the epithelium, endothelium, leukocytes, and platelets. Here, we examine the use of human platelet membrane-coated nanoparticles (PNPs) as a biomimetic decoy strategy to neutralize S. aureus toxins and preserve host cell defense functions. The PNPs blocked platelet damage induced by S. aureus secreted toxins, thereby supporting platelet activation and bactericidal
activity. Likewise, the PNPs blocked macrophage damage induced by S. aureus secreted toxins, thus supporting macrophage oxidative burst, nitric oxide production, and bactericidal activity, and diminishing MRSA-induced neutrophil extracellular trap release. In a mouse model of MRSA systemic infection, PNP administration reduced bacterial counts in the blood and protected against mortality. Taken together, the results from the present work provide a proof of principle of the therapeutic benefit of PNPs in toxin neutralization, cytoprotection, and increased host resistance to invasive S. aureus infection.

Frontiers of Engineering Management 2015, Volume 2, Issue 4,   Pages 373-377 doi: 10.15302/J-FEM-2015056

Abstract: This paper presents a new space model developed by general value engineering/value management model. The authors take the function analysis, function optimization and function realization of the development object as the basic point, to get the final optimization structure by value evaluation, so as to improve the project quality and reduce the project cost. The final case shows that the application of this model can save about 18% of the time and considerable cost of the usually planned projects under the condition of quality assurance.

Photothermal materials for efficient solar powered steam generation

Fenghua Liu, Yijian Lai, Binyuan Zhao, Robert Bradley, Weiping Wu

Frontiers of Chemical Science and Engineering 2019, Volume 13, Issue 4,   Pages 636-653 doi: 10.1007/s11705-019-1824-1

Abstract: Solar powered steam generation is an emerging area in the field of energy harvest and sustainable technologies. The nano-structured photothermal materials are able to harvest energy from the full solar spectrum and convert it to heat with high efficiency. Moreover, the materials and structures for heat management as well as the mass transportation are also brought to the forefront. Several groups have reported their materials and structures as solutions for high performance devices, a few creatively coupled other physical fields with solar energy to achieve even better results. This paper provides a systematic review on the recent developments in photothermal nanomaterial discovery, material selection, structural design and mass/heat management, as well as their applications in seawater desalination and fresh water production from waste water with free solar energy. It also discusses current technical challenges and likely future developments. This article will help to stimulate novel ideas and new designs for the photothermal materials, towards efficient, low cost practical solar-driven clean water production.

Survey of design and security evaluation of authenticated encryption algorithms in theCAESARcompetition None

Fan ZHANG, Zi-yuan LIANG, Bo-lin YANG, Xin-jie ZHAO, Shi-ze GUO, Kui REN

Frontiers of Information Technology & Electronic Engineering 2018, Volume 19, Issue 12,   Pages 1475-1499 doi: 10.1631/FITEE.1800576

Abstract:

The Competition for Authenticated Encryption: Security, Applicability, and Robustness (CAESAR) supported by the National Institute of Standards and Technology (NIST) is an ongoing project calling for submissions of authenticated encryption (AE) schemes. The competition itself aims at enhancing both the design of AE schemes and related analysis. The design goal is to pursue new AE schemes that are more secure than advanced encryption standard with Galois/counter mode (AES-GCM) and can simultaneously achieve three design aspects: security, applicability, and robustness. The competition has a total of three rounds and the last round is approaching the end in 2018. In this survey paper, we first introduce the requirements of the proposed design and the progress of candidate screening in the CAESAR competition. Second, the candidate AE schemes in the final round are classified according to their design structures and encryption modes. Third, comprehensive performance and security evaluations are conducted on these candidates. Finally, the research trends of design and analysis of AE for the future are discussed.

Recognition of Fluvial Bank Erosion Along the Main Stream of the Yangtze River Article

Ge Yan, Heqin Cheng, Zeyu Jiang, Lizhi Teng, Ming Tang, Tian Shi, Yuehua Jiang, Guoqiang Yang, Quanping Zhou

Engineering 2022, Volume 19, Issue 12,   Pages 50-61 doi: 10.1016/j.eng.2021.03.027

Abstract:

Recognizing the risk of fluvial bank erosion is an important challenge to ensure the early warning and prevention or control of bank collapse in river catchments, including in the Yangtze River. This study introduces a geomorphons-based algorithm to extract river bank erosion information by adjusting the flatness from multibeam echo-sounding data. The algorithm maps 10 subaqueous morphological elements, including the slope, footslope, flat, ridge, peak, valley, pit, spur, hollow, and shoulder. Twenty-one flatness values were used to build an interpretation strategy for the subaqueous features of riverbank erosion. The results show that the bank scarp, which is the erosion carrier, is covered by slope cells when the flatness is 10°. The scour pits and bank scars are indicated by pit cells near the bank and hollow cells in the bank slope at a flatness of 0°. Fluvial subaqueous dunes are considered an important factor accelerating bank erosion, particularly those near the bank toe; the critical flatness of the dunes was evaluated as 3°. The distribution of subaqueous morphological elements was analyzed and used to map the bank erosion inventory. The analysis results revealed that the near-bank zone, with a relatively large water depth, is prone to form large scour pits and a long bank scarp. Arc collapse tends to occur at the long bank scarp to shorten its length. The varied assignment of flatness values among terrestrial, marine, and fluvial environments is discussed, concluding that diversified flatness values significantly enable fluvial subaqueous morphology recognition. Consequently, this study provides a reference for the flatness-based recognition of fluvial morphological elements and enhances the targeting of subaqueous signs and risks of bank failure with a range of multibeam bathymetric data.
