摘要： Protein colloidal nanoparticles(NPs)are ubiquitous present in nature and function as building blocks with multiple functions in both food formulations and biological processes.Food scientists are inspired by naturally occurring proteins to induce self-assembly behavior of protein by manipulating environmental parameters,providing opportunities to construct special and expected NPs.Zein and casein,the main proteins derived from corn and milk,are two examples of the most prevalently studied food proteins for nanoarchitectures in recent years.In this article,the compositions,structures,and physicochemical properties of these two proteins and casein derivatives are summarized as well as their interactions and characterizations.Strategies to fabricate zein-sodium caseinate based NPs are critically highlighted and illustrated.Particularly,applications such as encapsulation and delivery of bioactive compounds,producing food packaging for enhanced antioxidative and antimicrobial effects,and stabilization of emulsions to achieve fat replacement.Due to the imperative role of food proteins in diet composition,this review not only provides cutting-edge knowledge for nanoparticle construction but also opens new avenues for efficient utilization and exploitation of food proteins.

摘要： By tilting a plasma jet and rotating 360°,a large-area can be scanned and sterilized in a short time.Compared with the previous array device,this pipe has the significant advantages of high sterilization uniformity and low gas consumption.Firstly,a rotatable plasma jet device,which can control the swing and rotation of a jet pipe,is designed,and a corresponding theoretical model is established to guide the experiment.Secondly,with Staphylococcus aureus(S.aureus)and Escherichia coli(E.coli)as the target bacteria,the device achieves a short sterilization time of 158 s—the minimum sterilization flow of S.aureus and E.coli is 0.8 slm and 0.6 slm,respectively.The device is compared with an array plasma sterilization device in terms of sterilization speed and gas consumption.The results show that the device is not only better than an array plasma sterilization device with respect to scanning uniformity,but also far less than the array plasma sterilization device in gas consumption of 5 slm.Therefore,the device has great potential in applications involving efficient,large-area sterilization.

摘要： Prodigiosin is a red pigment with a pyrrolylpyrromethane skeleton.It is mainly produced by bacterial strains belonging to the Serratia genus,but also by some other genera,including Streptomyces and Vibrio.Within the genus Serratia,the pigment is generally produced as a virulence factor.However,it also has many important beneficial biological activities such as immunosuppressive and anti-proliferative activities.Moreover,the pigment has many industrial applications in textile and cosmetics.In this mini-review,we discuss the genetic and molecular mechanisms supporting prodigiosin synthesis and production from the Serratia genus,as well as its potential applications.

摘要： Ransomware is considered one of the most threatening cyberattacks.Existing solutions have focused mainly on discriminating ransomware by analyzing the apps themselves,but they have overlooked possible ways of hiding ransomware apps and making them difficult to be detected and then analyzed.Therefore,this paper proposes a novel ransomware hiding model by utilizing a block-based High-Efficiency Video Coding(HEVC)steganography approach.The main idea of the proposed steganography approach is the division of the secret ransomware data and cover HEVC frames into different blocks.After that,the Least Significant Bit(LSB)based Hamming Distance(HD)calculation is performed amongst the secret data’s divided blocks and cover frames.Finally,the secret data bits are hidden into the marked bits of the cover HEVC frame-blocks based on the calculated HD value.The main advantage of the suggested steganography approach is the minor impact on the cover HEVC frames after embedding the ransomware while preserving the histogram attributes of the cover video frame with a high imperceptibility.This is due to the utilization of an adaptive steganography cost function during the embedding process.The proposed ransomware hiding approach was heavily examined using subjective and objective tests and applying different HEVC streams with diverse resolutions and different secret ransomware apps of various sizes.The obtained results prove the efficiency of the proposed steganography approach by achieving high capacity and successful embedding process while ensuring the hidden ransomware’s undetectability within the video frames.For example,in terms of embedding quality,the proposed model achieved a high peak signal-to-noise ratio that reached 59.3 dB and a low mean-square-error of 0.07 for the examined HEVC streams.Also,out of 65 antivirus engines,no engine could detect the existence of the embedded ransomware app.

摘要： This paper investigates the social networks usage by students in Abidjan city, Côte d’Ivoire. We focus on a descriptive or quantitative analysis to understand the motivations and how students make use of internet and social networks. More than six hundred forms were distributed to persons we have deemed as students. In return, we received more than 93% of the forms that have been processed. The study highlights the materials and the digital platforms that students used the most. The majority of the respondents reported to have access to the social networks in their mobile phones, with WhatsApp leading this application ranking, followed by Instagram, Facebook, YouTube, and Tik Tok. The survey shows that two third of our respondents are aged from 19 to 25 years old and almost half of the respondents spend daily 2 to 5 hours on digital platforms. The investigation also reveals that the main online activities are the e-commerce, chatting, information, and entertainment. The paper addresses also the online harassment of the students and it shows that more than one tenth of them have been victims of cyber-bullying. This study might be useful for governments, institutions, academia, individuals and professionals in order to communicate efficiently with a given population for a better use of social networks and to prevent students from harassment.

摘要： Recent research efforts have created rapid advances in the field of the Internet of Things (IoT) in terms of communication protocols, sensing technologies, computing capabilities, next-generation wireless technologies, big data and AI techniques, and on-device, edge, cloud processing. These advances created a paradigm shift and generated a wide range of potential opportunities for a new major field known as the Internet of Medical Things (IoMT), as well as subfields like mobile Health (mHeatlh) and digital or electronic Health (eHealth). This paper provides an overview of the Internet of Medical Things and presents a classification to define the primary users and their roles and involvement in smart healthcare systems. The paper then presents taxonomy on the deployment scales of different healthcare environments, from personal healthcare to widescale connected healthcare systems. The overview also discusses the n-tier architecture of IoMT, then presents a set of taxonomies and classifications on the different medical devices used in healthcare systems as well as non-medical devices used to provide context-aware information about the surrounding environment. The paper then concludes the overview by presenting the different healthcare-related applications and services, a comparison between traditional and smart healthcare systems, and the different obstacles and challenges in the field of IoMT to guide the development of new services and devices. Many survey papers in the literature focused on similar points;however, up to our knowledge, this is the first paper to present taxonomies and classifications for these IoMT essential topics. The presented taxonomies and classifications provide the manufacturers of medical devices and the developers of healthcare services a deeper understanding of the healthcare systems’ landscape to address different requirements and demands.

摘要： The field of supramolecular assemblies has developed rapidly in the last few decades,thanks in a large part to their diverse applications.These assemblies have been mostly based on Werner-type coordination motifs in which metal centres are coordinated by nitrogen or oxygen donors.Recently,N-heterocyclic carbene(NHC)ligands have been employed as carbon donors not only because of their appealing structures but also due to the extensive applications in catalysis,biomedicine and material science of the resulting assemblies.During the last decade,NHC-based supramolecular assemblies have witnessed rapid growth and extensive application in molecular recognition,luminescent materials and catalysis.For different topological systems,a diverse selection of poly-NHC precursors and synthetic strategies is crucial to precisely control the synthesis of supramolecular architectures.Several synthetic strategies have been developed to synthesise two-dimensional(2D)molecular metallacycles and three-dimensional(3D)metallacages from a wide range of poly-NHC precursors,including a straightforward one-pot strategy,supramolecular transmetalation,stepwise synthesis,an improved one-pot strategy involving self-sorting behaviour of 3D metallacages and a subtle variation strategy of poly-NHC ligand precursors.This review offers a summary of the synthetic strategies applied for the construction of different poly-NHC-based supramolecular assemblies,particularly emphasizes recent progress in the synthesis of large and complex supramolecular assemblies from poly-NHC precursors,and further attention is given to their application in postsynthetic modifications(PSMs),host-guest chemistry,luminescent properties and biomedical applications.

摘要： The last two decades has seen a major development is the Strategic Environmental Assessment process in Hong Kong. One of the first SEA's was that undertaken as part of the Port and Airport Development Strategy Study. One of the hallmarks of that SEA was that extensive mathematical modelling was able to be conducted as essentially "money was no object and time was plentiful". However times change and it is generally the case that the expectations of the outcome are inversely proportional to time and budget.
