MAC-Based Physical Layer Security over Wireless Sensor Network
Physical layer security for wireless sensor networks (WSNs) is a laborious and highly critical issue in the world. Wireless sensor networks have great importance in civil and military fields or applications. Security of data/information through wireless medium remains a challenge. The data that transmit wirelessly has increased the speed of transmission rate. In physical layer security, the data transfer between source and destination is not confidential, and thus the user has privacy issues, which is why improving the security of wireless sensor networks is a prime concern. The loss of physical security causes a great threat to a network.

GPS-aided GEO Augmented Navigation
The GPS-aided GEO augmented navigation (GAGAN) is an implementation of a regional satellite-based augmentation system (SBAS) by the Government of India. It is a system to improve the accuracy of a GNSS receiver by providing reference signals. The AAI's efforts towards implementation of operational SBAS can be viewed as the first step towards introduction of modern Communication, navigation and surveillance/Air Traffic Management system over Indian airspace. The project has established 15 Indian reference stations, 3 Indian navigation land uplink stations, 3 Indian mission control centers, and installation of all associated software and communication links. It will be able to help pilots to navigate in the Indian airspace by an accuracy of 3 m. This will be helpful for landing aircraft in marginal weather and difficult approaches like Mangalore and Leh airports.

Trichiida
Trichiida (synonymous with Trichiales T.Macbrd.) is an order of slime moulds in the phylum Amoebozoa. Trichiida is one of five orders in the group Myxomycetes (also called Myxogastria), or the true plasmodial slime molds. It is also currently categorized under the superorder Lucisporidia with its sister group, Liceida. The order was first described by Thomas MacBride in 1922, and has retained the same name and status as a defined order in present phylogeny. In the plasmodium form, members of Trichiida lack a columella but have a well-developed capillitium for spore dispersal. The shape and details of the capillitium are used to define families within the order. Spores are brightly coloured, ranging from clear, white and yellow to pink and red-brown tones. The order currently has 4 families, 14 genera and 174 species. Recent molecular research has shown that while Trichiida probably represents a true taxonomic group, its sister group Liceida is likely paraphyletic, and it has been suggested that several genera from the Liceida should be reclassified under Trichiida instead.

War Office Selection Boards
War Office Selection Boards, or WOSBs, were a scheme devised by British Army psychiatrists during World War II to select potential officers for the British Army. They replaced an earlier method, the Command Interview Board, and were the precursors to today's Army Officer Selection Boards. The WOSBs were also later adapted to civilian purposes such as selecting civil servants and firemen.

Redox-Active Metals in Dopaminergic Neuronal Death
Biometals are all metal ions that are essential for all living organisms. About 40% of all enzymes with known structures require biometals to function correctly. The main target of damage by biometals is the central nervous system (CNS). Biometal dysregulation (metal deficiency or overload) is related to pathological processes. Chronic occupational and environmental exposure to biometals, including iron and copper, is related to an increased risk of developing Parkinson’s disease (PD). Indeed, biometals have been shown to induce a dopaminergic neuronal loss in the substantia nigra. Although the etiology of PD is still unknown, oxidative stress dysregulation, mitochondrial dysfunction, and inhibition of both the ubiquitin–proteasome system (UPS) and autophagy are related to dopaminergic neuronal death.

Organ-on-Chip Models for Mimicking Joint Microenvironment
Osteoarthritis (OA) remains a prevalent disease affecting more than 20% of the global population, resulting in morbidity and lower quality of life for patients. The study of OA pathophysiology remains predominantly in animal models due to the complexities of mimicking the physiological environment surrounding the joint tissue. Development in microfluidic organ-on-chip (OoC) systems have demonstrated various techniques to mimic and modulate tissue physiological environments. Adaptations of these techniques have demonstrated success in capturing a joint tissue’s tissue physiology for studying the mechanism of OA.

Carbon Capture Technologies
With an increase in the global population and the subsequent rise in energy demands and waste generation, the rate of CO2 release is at a much faster rate than its recycling through photosynthesis or fixation, which increases its net accumulation in the atmosphere. A large amount of CO2 is emitted into the atmosphere from various sources such as the combustion of fossil fuels in power plants, vehicles and manufacturing industries. Thus, carbon capture plays a key role in the race to achieve net zero emissions, paving a path for a decarbonized economy.

Agile for Public Administration during the COVID-19 Crisis
During the COVID-19 pandemic (and associated lockdowns), the need to digitalise public administration services and processes grew strongly, and digitalisation has emerged as an important enabler of good governance and an essential factor in the functioning of all segments of society. In particular, the mentioned pandemic was a very specific crisis with drastic restriction measures on the one hand and the availability of information and communication technology (ICT) infrastructure on the other. The pandemic has provided significant windows of opportunity for a radical digital transformation of public administration. More digital practices have been introduced around the world at different speeds, seeing the levels of the digitalisation of public services and processes rising exponentially compared to in the past. To increase the flexibility, responsiveness, adaptability, and resilience of public administrations in times of crisis, accelerated digitalisation and “agile” as a management concept (hereinafter: agile) could be adopted for them to function in line with good governance principles in today’s VUCA world.

WAAM of Duplex Stainless Steels
WAAM (Wire and Arc Additive Manufacturing) is becoming an increasingly popular method to produce components from metals which are usually not so suitable for conventional production methods. One of the good examples is duplex stainless steels (DSS), which are quite complex for welding and machining. Excessive ferrite amount is a common problem for them and controlling an interlayer temperature could offer a solution. However, using too low interlayer temperature will slow down the whole process and compromise one of the WAAM’s main advantages - the high productivity. Aim of this study is to find the relationship between interlayer temperature and process duration and to determine the influence of the interlayer temperature on product structure and other properties. Three samples (walls) were made using different interlayer temperatures (50 °C, 100 °C and 150 °C) and they were tested to analyze their surface texture, chemical composition, ferrite amount, the appearance of porosity and the hardness. Ferrite amount was higher and there was more porosity on lower interlayer temperatures, while there is no significant difference between surface texture and chemical composition for the samples. Considering the fact that higher interlayer temperatures provide a faster process, they should be preferred to produce duplex stainless steel products.

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.

Tremor Suppression Devices
Tremors are the most prevalent movement disorder that interferes with the patient’s daily living, and physical activities, ultimately leading to a reduced quality of life. Due to the pathophysiology of tremor, developing effective pharmacotherapies, which are only suboptimal in the management of tremor, has many challenges. Thus, a range of therapies are necessary in managing this progressive, aging-associated disorder. Surgical interventions such as deep brain stimulation are able to provide durable tremor control. However, due to high costs, patient and practitioner preference, and perceived high risks, their utilization is minimized. Medical devices are placed in a unique position to bridge this gap between lifestyle interventions, pharmacotherapies, and surgical treatments to provide safe and effective tremor suppression.
