Cryptocurrency and Blockchain Technology
Cryptocurrency has exploded in popularity, with Bitcoin adopted as a national currency in two countries. The blockchain technology on which cryptocurrency is built is an important tool used not only to facilitate a medium of exchange but also in many industries, including healthcare and education. As with all technologies, blockchain is a tool and can be abused by malicious actors. However, the decentralised nature of the technology creates an obstacle to establishing jurisdiction in transnational crimes.

Chinese Cyberwarfare
China is both the world's second-largest economy and a nuclear weapons state with the world's second-largest defense budget. Chinese Information Operations and Information Warfare includes the concept of “network warfare”, which is roughly analogous to the United States concept of cyber-warfare. Foreign Policy magazine provided an estimated range for China's "hacker army" personnel, anywhere from 50,000 to 100,000 individuals. Western countries have long accused China of aggressive espionage, and while investigations have traced various attacks on corporate and infrastructure computer systems to have originated in China , "it is nearly impossible to know whether or not an attack is government-sponsored because of the difficulty in tracking true identities in cyberspace." China has denied these accusations of cyber-warfare and has, in turn, accused the United States of engaging in cyber-warfare against China - a claim the US government denies.

Prompt (Command)
This article presents a list of commands used by DOS operating systems, especially as used on x86-based IBM PC compatibles (PCs). Other DOS operating systems are not part of the scope of this list. In DOS, many standard system commands were provided for common tasks such as listing files on a disk or moving files. Some commands were built into the command interpreter, others existed as external commands on disk. Over the several generations of DOS, commands were added for the additional functions of the operating system. In the current Microsoft Windows operating system, a text-mode command prompt window, cmd.exe, can still be used.

U-Net_dc
Mutated cells may constitute a source of cancer. As an effective approach to quantifying the extent of cancer, cell image segmentation is of particular importance for understanding the mechanism of the disease, observing the degree of cancer cell lesions, and improving the efficiency of treatment and the useful effect of drugs. However, traditional image segmentation models are not ideal solutions for cancer cell image segmentation due to the fact that cancer cells are highly dense and vary in shape and size. To tackle this problem, researchers propose a novel U-Net-based image segmentation model, named U-Net_dc, which expands twice the original U-Net encoder and decoder and, in addition, uses a skip connection operation between them, for better extraction of the image features.

Artificial Intelligence Techniques in Concrete
Due to the speed of artificial intelligence (AI) techniques in solving engineering problems, there has been a tendency to use these techniques in various fields of civil engineering, including designing construction materials (concrete mixtures for example) or estimating their properties.  As it is hard to predict the compressive strength of concrete due to the different nonlinearities inherent in the mixture designs, various concrete companies are continuously looking to use new methods and technologies to predict the compressive strength. Such methods include numerical modelling and artificial intelligence due to their advantages.

Processing and Analysis of Label-Free Images
Time-lapse microscopy imaging is a key approach for an increasing number of biological and biomedical studies to observe the dynamic behavior of cells over time which helps quantify important data, such as the number of cells and their sizes, shapes, and dynamic interactions across time. Label-free imaging is an essential strategy for such studies as it ensures that native cell behavior remains uninfluenced by the recording process.

Alternative Models of Graph Visualization
There are many data visualization tools in various application fields, but at the same time, the main difficulty lies in presenting data of an interconnected (node-link) structure, i.e., networks. Typically, a lot of software means use graphs as the most straightforward and versatile models. To facilitate visual analysis, researchers are developing ways to arrange graph elements to make comparing, searching, and navigating data easier.

Epileptic Seizure Prediction Approaches
Electroencephalography (EEG) signals are the primary source for discriminating the preictal from the interictal stage, enabling early warnings before the seizure onset. Epileptic seizure prediction systems face significant challenges due to data scarcity, diversity, and privacy.

Product Promotion in Internet Market
The influence of Internet marketing has grown so much that producers must now reconfigure their businesses from offline operation to online presence simply to meet user expectations. Thus, the development of an intelligent information system for product promotion online is quite relevant. It may lead to automatized selection of competing products and advertising content, a subsequent increase in the effectiveness of advertisements, and a decrease in costs for Internet ad placements.
