A number of cybercriminals have been targeting Android in recent times due to its popularity. As a result of the increasing demand for smartphones, malicious users have recently been drawn to Android and taken advantage of its open system design to commit crimes. As Android has grown in popularity, attackers have been targeting it more. It is possible to gain access to data hidden from view using algorithms even though security measures have been implemented. An Android malware detection system based on machine-deep learning has been developed by utilizing dynamic analysis, in which suspected malware is executed in a secure environment in order to observe its behavior, as well as static analysis, in which malware files are examined without being executed on an Android device. As a result of our experimental results, our suggested models have a higher accuracy rate than industry standards, with a static accuracy rate of 99 and a dynamic accuracy rate of 98 for CNN-LSTM","PeriodicalId":16381,"journal":{"name":"JOURNAL OF NANOSCOPE (JN)","volume":"69 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135684780","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The optimum yield of bio-biodiesel was obtained 92% from Jatropha Curcas seed oil. SEM shows the surface morphology, topography, composition, crystallographic and structural shape of synthesized Cu-ZnO nano catalyst. XRD and EDX results depicted good morphology of prepared catalyst. XRD and EDX also displays the pattern of a model Cu-ZnO. FTIR results showed the major functional groups identified were alkanes , aromatics and carboxylic acid . Among these functional groups, alkanes were qualitatively noted to be the main constituents which indicate the good catalytic cracking activity of the catalyst.The UV, absorbance peak indicated the presence of ZnO nanoparticles, which is in accordance of UV absorbance result shown by previous studies. The effect of temperature on biodiesel yield showed from higher yield with 45 o C from 64.33 to 80 ml of ethanol concentration at 45 o C. On further rise in temperature resulted 92% product yield. Furthermore, effect of methanol on bio- diesel yield showed that, as the methanol ratio subsequently increased from 1: 05 to 1: 12increased the product yield.

They allow healthcare providers to track patient health records, evaluate treatments and outcomes, and identify trends and patterns in disease diagnosis and management. Additionally, medical data sets are used for training AI models that can assist healthcare professionals in diagnosing and treating diseases, providing accurate and timely patient care, and reducing medical errors. \u0000In recent years millions of patient records have already been compromised due to data thefts in the healthcare industry ranging from patient’s private health data to hospitals accounting, reporting, DNA structures etc.  are all being taken. Blockchain technology, which is regarded as a trustworthy way to maintain documents, could be utilized to protect full security and confidentiality. This approach would not only safeguard patient data but also due to decentralized structure of a technology it also lead to more efficient treatment of patients as information would be readily and instantly available. Therefore, proper implementation of the blockchain system will not only increase individual service but also remove the need for external parties to provide security. \u0000The study proposed a model that would unites almost all of the leading healthcare providers, by combining all Electronic Health Record (EHR) system including hospitals, clinics, and specialized Laboratories as well. MedBloc, a blockchain-based safe EHR system that offers accessibility, safety, and protection is described. It allows both patients and healthcare professionals to view and exchange medical records, by extracting important ideas that can be used to create multiple blockchain systems and vulnerability scanning that address security flaws. This article also presents blockchain vulnerability management options by analyzing some assaults upon blockchain, including hashing, connectivity, smart contract and privacy breach cyberattacks. It has been proven difficult as a result of trustworthy attack analysis techniques. Therefore, we explore the blockchain's user privacy in this paper and consider potential fixes.
