Forensic Limnology
Forensic limnology is a sub-field of freshwater ecology, which focuses especially on the presence of diatoms in crime scene samples and victims. Different methods are used to collect this data but all identify the ratios of different diatom colonies present in samples and match those samples with locations at the crime scene.

Internet of Medical Things applications
The Internet of Things (IoT) have been adopted by several areas of the society, such as smart transportation systems, smart cities, smart agriculture, smart energy and smart healthcare. The healthcare is an area that takes a lot of benefits from IoT technology (composing the Internet of Medical Things (IoMT)), since low cost devices and sensors can be use to create medical assistance systems, reducing the deployment and maintenance costs, and at the same time, improving the patients and their family quality of life. However, only IoT is not able to support the complexity of e-health applications. For instance, sensors can generate large amount of data, and the IoT devices do not have enough computational capabilities to process and store these data. Thus, the cloud and fog technologies emerge to mitigate the IoT limitations, expanding the IoMT applications capacities. The cloud computing provides virtual unlimited computational resources, while the fog push the resources closest to the end users, reducing the data transfer latency. Therefore, the IoT, fog, and cloud computing integration provides a robust environment to e-health systems deployment, allowing a plenty of different types of IoMT applications. In this topic review, we present an overview of a systematic mapping with the goal to overview the current state-of-the-art in IoMT applications using IoT, fog and cloud infrastructures.

Nontransitive Dice
A set of dice is nontransitive if it contains three dice, A, B, and C, with the property that A rolls higher than B more than half the time, and B rolls higher than C more than half the time, but it is not true that A rolls higher than C more than half the time. In other words, a set of dice is nontransitive if the binary relation – X rolls a higher number than Y more than half the time – on its elements is not transitive. It is possible to find sets of dice with the even stronger property that, for each die in the set, there is another die that rolls a higher number than it more than half the time. Using such a set of dice, one can invent games which are biased in ways that people unused to nontransitive dice might not expect (see Example).

Polycom
Polycom, now a part of Plantronics, was an American multinational corporation that develops video, voice and content collaboration and communication technology. Polycom was co-founded in 1990 by Brian L Hinman and Jeffrey Rodman. In 2018 Polycom was acquired by Plantronics and in 2019 the name of the combined entity was changed to Poly. On March 28, 2022 HP Inc. announced it would be acquiring Poly (company) in a deal totaling $1.7 billion USD.

Graphics Environment Manager
GEM (for Graphics Environment Manager) was an operating environment created by Digital Research (DRI) for use with the DOS operating system on Intel 8088 and Motorola 68000 microprocessors. GEM is known primarily as the graphical user interface (GUI) for the Atari ST series of computers, and was also supplied with a series of IBM PC-compatible computers from Amstrad. It also was available for standard IBM PC, at the time when the 6 MHz IBM PC AT (and the very concept of a GUI) was brand new. It was the core for a small number of DOS programs, the most notable being Ventura Publisher. It was ported to a number of other computers that previously lacked graphical interfaces, but never gained popularity on those platforms. DRI also produced X/GEM for their FlexOS real-time operating system with adaptations for OS/2 Presentation Manager and the X Window System under preparation as well.

SUSE Linux Enterprise Desktop
SUSE Linux Enterprise Desktop (SLED), introduced as Novell Linux Desktop, is a Linux distribution supplied by SUSE and targeted at the business market. It is targeted for desktops. New major versions are released at an interval of 24–36 months, while minor versions (called service packs) are released every 9–12 months. SUSE Linux Enterprise products, including SUSE Linux Enterprise Desktop, receive commercial support and much more intense testing than the openSUSE community product, with the intention that only mature, stable versions of the included components will make it through to the released enterprise product. The current version is SLED 15, which is developed from a common codebase with SUSE Linux Enterprise Server (SLES) and other SUSE Linux Enterprise (SLE) products. SLED includes the GNOME Shell, LibreOffice, Evolution and many other popular open source packages such as Dia, TigerVNC, and lftp. Like SLES, SLED is based on openSUSE Tumbleweed and shares a common codebase with openSUSE Leap. On 15 March 2019, EQT Partners completed its acquisition of SUSE for 2.5 billion USD, leaving SUSE one of the largest independent enterprise Linux vendors.

Technologies for Down Syndrome Persons
Since the beginning of the 21st century, the lifespan of people born with Down syndrome (DS) has increased. They now outlive their parents and rely on their relatives who usually sacrifice their own families to care for their disabled siblings. To reduce the pressure on families and the wider community, it is crucial to prepare DS people for independent life from early childhood. Emerging technologies can significantly support the process of acquiring the skills that are necessary for solving real-life problems at home and work.

NNetEn Entropy
NNetEn is the first entropy measure that is based on artificial intelligence methods. The method modifies the structure of the LogNNet classification model so that the classification accuracy of the MNIST-10 digits dataset indicates the degree of complexity of a given time series. The calculation results of the proposed model are similar to those of existing methods, while the model structure is completely different and provides considerable advantages.

Artificial Neural Networks for Navigation Systems
Several machine learning (ML) methodologies are gaining popularity as artificial intelligence (AI) becomes increasingly prevalent. An artificial neural network (ANN) may be used as a “black-box” modeling strategy without the need for a detailed system physical model. It is more reasonable to solely use the input and output data to explain the system’s actions. ANNs have been extensively researched, as artificial intelligence has progressed to enhance navigation performance. In some circumstances, the Global Navigation Satellite System (GNSS) can offer consistent and dependable navigational options. A key advancement in contemporary navigation is the fusion of the GNSS and inertial navigation system (INS). Numerous strategies have been put out to increase the accuracy for jamming, GNSS-prohibited environments, the integration of GNSS/INS or other technologies by means of a Kalman filter as well as to solve the signal blockage issue in metropolitan areas. A neural-network-based fusion approach is suggested to address GNSS outages.

GQL Graph Query Language
In September 2019 a proposal for a project to create a new standard graph query language (ISO/IEC 39075 Information Technology — Database Languages — GQL). was approved by a vote of national standards bodies which are members of ISO/IEC Joint Technical Committee 1(ISO/IEC JTC 1). JTC 1 is responsible for international Information Technology standards. GQL is intended to be a declarative database query language, like SQL.
