Bandwidth Improvement in Ultrasound Image Reconstruction Using Deep Learning Techniques

Ultrasound (US) imaging is a medical imaging modality that uses the reflection of sound in the range of 2–18 MHz to image internal body structures. In US, the frequency bandwidth (BW) is directly associated with image resolution. BW is a property of the transducer and more bandwidth comes at a higher cost. Thus, methods that can transform strongly bandlimited ultrasound data into broadband data are essential. In this work, we propose a deep learning (DL) technique to improve the image quality for a given bandwidth by learning features provided by broadband data of the same field of view. Therefore, the performance of several DL architectures and conventional state-of-the-art techniques for image quality improvement and artifact removal have been compared on in vitro US datasets. Two training losses have been utilized on three different architectures: a super resolution convolutional neural network (SRCNN), U-Net, and a residual encoder decoder network (REDNet) architecture. The models have been trained to transform low-bandwidth image reconstructions to high-bandwidth image reconstructions, to reduce the artifacts, and make the reconstructions visually more attractive. Experiments were performed for 20%, 40%, and 60% fractional bandwidth on the original images and showed that the improvements obtained are as high as 45.5% in RMSE, and 3.85 dB in PSNR, in datasets with a 20% bandwidth limitation.

Results reported in this paper revealed significant security vulnerabilities in several popular kids’ smartwatches when exploited by SMS command injection, Bluetooth tracking and Wi-Fi man in the middle attack. The devices investigated were kids’ smartwatches, a fitness tracker and a smart phone with varying functions, connections and security features. Findings of the paper raise concerns as vulnerabilities of kids’ IoT smart devices can lead to criminal cases, such as child grooming and child abduction.
Profiling Cyber Attackers by Classification Techniques; A Case Study on Russian Hackers

Cyber-attacks have become increasingly common in recent years all over the world. In particular, the ongoing unfortunate events between Russia and Ukraine have been aided using technology. The Russians have used various types of attacks for various reasons, such as reconnaissance to gather information about Ukraine's critical systems. It is critical to be able to profile these types of attacks for identification and other strategies to prevent such attacks in the future. Data mining techniques can be used to profile hackers by nation states, law enforcement agencies, and organizations alike. Profiling hackers can assist in better preparing for and responding to cyber-attacks. The goal of this study is to use data mining techniques to profile Russian hackers. Another important aspect of this study is the dataset that will be used, OSINT. The open-source dataset was chosen because it is free, suitable for research, and widely available. Different classification algorithms will be used to train the proposed predictors, and the most reliable and accurate model will be chosen. This study emphasizes the importance of better understanding well known Russian hacker groups, which could lead to better preparation and handling of cyber incidents involving such threat actors. Nation-state governments, researchers, and law enforcement agencies can use the developed model in conjunction with other techniques to quickly identify attacks from Russia APT groups, recommend controls, and develop a detailed strategy for countermeasures against such attacks, which will improve data security and privacy.
An Analysis of Cybersecurity Data Breach in the State of California

As the wave of data breaches continues to crash down on organisations, we will analyse the largest publicly available database of data breaches in the state of California using the public data breach database functioning under the state notification law of data breach. The dataset contains records since January 2012. These records were analysed in order to classify and identify California data breaches by multiple company types, attack vectors and stolen personal information. The main findings were that Software vulnerability is the most common attack vector due to third-party software, the financial industry is the most targeted industry while both large and small organisations are equally targeted by attackers. The analysis also found that credit/debit card information and social security numbers represent the most stolen personal information.
Towards Collaborative Security Approaches Based on the European Digital Sovereignty Ecosystem

The need for collaboration and digital transformation is among the lessons the world has realized during the pandemic. This chapter argues that the strategy of the European Union to bring the concepts of sovereignty to the digital world is a crucial enabler to achieve these two goals. This strategy is being shaped by several community initiatives, laws, and projects that tackle different aspects of digital sovereignty. In this chapter, we survey the relevant literature to present an understanding of the emerging technology and highlight a research agenda based on challenges and gaps that we identify in different topics. Next, we discuss the requirements and challenges of identity and trust, sovereign data exchange, federated catalogues, and compliance as digital sovereignty pillars. This discussion is helpful to researchers in identifying relevant problems and practitioners in designing future-proof solutions. Finally, we illustrate the benefits of digital sovereignty through a use-case from the domain of collaborative security approaches.
The Digital Discourse of Romanian Social Media Prosumers During the Covid-19 Pandemic

"The Digital Discourse of Romanian Social Media Prosumers during the COVID-19 Pandemic. Social media platforms provide the digital playground for users to manifest a strong form of clicktivism and, at the same time, a deep sense of belonging. In this digital space, users produce discourses with in-built ideologies which have a strong impact on society. Through digitized practices (following, sharing, commenting, posting), users become social actors who design and redesign their behaviour and life choices in relation to the individuals and groups which they follow online on a regular basis. In the context of the Covid-19 pandemic, through the use of social media, various users have become movers and shakers in Romania. This study aims to analyse the new media discourse showing the Romanian people’s attitude towards the Covid-19 pandemic in the time span of September-October 2021. As such, the linguistic manifestation of users (including micro-celebrities and public figures) was reflected in the polarization of Romanian society, resulting in people mistrusting authorities, and medical experts and giving voice to users who would not normally have a voice in the matter of a global pandemic. Keywords: clicktivism, digital discourse, digitized practices, prosumers, debunking "
Exploring Liminal Aesthetics: the “Glitchy and Decayed” Worlds of Vaporwave, Semiotic Assemblages, and Internet Linguistics

"Exploring Liminal Aesthetics: The “Glitchy and Decayed” Worlds of Vaporwave, Semiotic Assemblages, and Internet Linguistics. The topic of online identity formation in the realm of computer-mediated communication is nothing new. However, what does stand out, especially in recent years, in the larger framework of Internet-based sociolinguistic practices (David 2010; Williams 2006), is a much-needed exploration of various new microcultural aggregates. Some of these niche-genres are frequently encountered on YouTube, while others are primarily short-lived Instagram or TikTok community-driven trends. In essence, this paper states the belief that it is precisely these relatively contemporary microcultural trends that manage to accurately take the pulse of a new, post-pandemic world. Moreover, since many of these forms of artistic self-expression can be understood through a Cultural Sociolinguistic lens (Cotrău, Cotoc, and Papuc 2021), a translation of their particular symbolic meanings can only help decipher the increasingly chaotic, hypersubjective, and “semiotic assemblages” (Pennycook 2017) that individuals seem to be inhabiting and creating. Thus, the current paper aims to offer an analysis that ties together an array of only seemingly disparate elements, namely: cultural economy, creation and consumption of online cultural artefacts, and an affective processing that ties real-life traumatic events to the creation of particular cultural trends - liminal aesthetics and vaporwave, paired with a fascination with all things “glitchy and decayed” (Loignon and Messier 2020). Keywords: online identity, sociolinguistics, Internet linguistics, multimodality, vaporwave, liminal aesthetics, semiotic assemblages "
The Role of Blockchain to Reduce the Dissemination of Fake News on Social Media and Messaging Platforms

The world is progressing further into the digital era, and as a result, more and more people are getting their initial information from online news portals and social media platforms. The dependence on sources of information that are becoming murkier raises the likelihood of being deceived and the possibility of misguided agendas. When it comes to verifying articles, traditional news outlets adhere to stringent norms of practice. In contrast, people nowadays are able to publish news items on social media and unverified sites without having to provide evidence that they are true. Because there are now no indicators on the Internet that can be used to gauge the veracity of such news pieces, an innovative strategy that makes use of technology is required in order to evaluate the realness quotient of unconfirmed news items. This paper proposes a dynamic model with a secure voting mechanism that allows news reviewers to submit news input. A probabilistic mathematical model is utilised to estimate the news item’s veracity based on the feedback obtained from the news reviewers. In order to guarantee that the information being spread is accurate, the concept, which is based on blockchain technology, will be presented.
Content-Based Satellite Image Retrieval on Edge Detection Algorithm and Compression with ACO During Boundaries Analysis

Present research is focused on content-based satellite image retrieval. Boundaries of satellite images have been analyzed using edge detection and compression technique. Edge detection and compression in ant colony optimization and image processing are the subject of current research. The suggested study is centered on the integration of ACO with an edge detection technique and compression. Detection of edges, optimization of ant colonies, and image processing are all topics that have been studied in the past. The difficulties that have been addressed in earlier research are included in the problem statement. According to ant colony optimization requirements, edge detection is necessary when it comes to image processing. Edge detection is also used for image processing, and this is done using the edge detection approach. Edge detection pictures have been studied for contrast, correlation, and entropy as well as for energy, variance, deviation, smoothness, and skewness throughout the feature extraction process.
