Google+
Google Plus (stylized as Google+) is an Internet-based social network that is owned and operated by Google. The service, Google's fourth foray into social networking, experienced strong growth in its initial years, although usage statistics have varied, depending on how the service is defined. Three Google executives have overseen the service, which has undergone substantial changes leading to a redesign in November 2015. On October 8, 2018, Google announced that it was shutting down Google+ for consumers, citing low user engagement and a software error, first reported by The Wall Street Journal , that potentially exposed the data of hundreds of thousands of users. Google indicated that Google+ would operate until August 2019, allowing users to download and migrate their information.

Development Progress of TOPCon Solar Cells
In addition to the different technologies of silicon solar cells in crystalline form, TOPCon solar cells have an exceptionally great efficiency of 26%, accomplished by the manufacturing scale technique for industrialization, and have inordinate cell values of 732.3 mV open-circuit voltage (Voc) and a fill factor (FF) of 84.3%. A silicon layer doped with phosphorus and a very thin tunnel oxide form TOPCon. The thickness of tunnel oxide, which is less than 2 nm in the TOPCon cell, primarily affects the electrical properties and efficiency of the cell.

High-level Architecture
The high-level architecture (HLA) is a general purpose architecture for distributed computer simulation systems. Using HLA, computer simulations can interact (that is, to communicate data, and to synchronize actions) with other computer simulations regardless of the computing platforms. The interaction between simulations is managed by a run-time infrastructure (RTI). HLA is an interoperability standard for distributed simulation used to support analysis, engineering and training in a number of different domains in both military and civilian applications and is the standard technical architecture for all US Department of Defense simulations.

Oppositional Defiant Disorder
Oppositional defiant disorder (ODD) is listed in the DSM-5 under Disruptive, impulse-control, and conduct disorders and defined as "a pattern of angry/irritable mood, argumentative/defiant behavior, or vindictiveness". This behavior is usually targeted toward peers, parents, teachers, and other authority figures. Unlike with conduct disorder (CD), those with oppositional defiant disorder are not aggressive towards people or animals, do not destroy property, and do not show a pattern of theft or deceit. It has certain links to ADHD (Attention Deficit Hyperactivity Disorder) and as much as one half of children with ODD will also diagnose as having ADHD as well.

Taiwanese Romanization System
The Taiwanese Romanization System (Taiwanese Romanization: Tâi-uân Lô-má-jī Phing-im Hong-àn, Chinese: 臺灣閩南語羅馬字拼音方案; pinyin: Táiwān Mǐnnányǔ Luómǎzì Pīnyīn Fāng'àn; Pe̍h-ōe-jī: Tâi-ôan Lô-má-jī Pheng-im Hong-àn; often referred to as Tâi-lô) is a transcription system for Taiwanese Hokkien. It is derived from Pe̍h-ōe-jī and since 2006 has been one of the officially promoted phonetic notation system by Taiwan's Ministry of Education. It is nearly identical to Taiwanese Language Phonetic Alphabet (TLPA) Romanization for Hakka apart from using ts tsh j instead of c ch j for the fricatives /ts tsʰ dz/.

Anti-Fungal Efficacy of Flavonoids
The prevalence of fungal infections is growing at an alarming pace and the pathogenesis is still not clearly understood. Recurrence of these fungal diseases is often due to their evolutionary avoidance of antifungal resistance. The development of suitable novel antimicrobial agents for fungal diseases continues to be a major problem in the current clinical field. Hence, it is urgently necessary to develop surrogate agents that are more effective than conventional available drugs. Among the remarkable innovations from earlier investigations on natural-drugs, flavonoids are a group of plant-derived substances capable of promoting many valuable effects on humans. The identification of flavonoids with possible antifungal effects at small concentrations or in synergistic combinations could help to overcome this problem. A combination of flavonoids with available drugs is an excellent approach to reduce the side effects and toxicity.

Plant Growth-Promoting Rhizobacteria
Plant growth-promoting bacteria (PGPR) are soil bacteria living in the rhizosphere which, through the secretion of various regulatory molecules, are involved in promoting plant growth and development. They can be found associated with the roots (rhizosphere), with the leaves (phyllosphere), or within the plant (endosphere). The endophytes (PGPE) are generally the most effective in supporting growth; being inside the plant tissues, they can communicate with the host plant and exert their beneficial effect much more efficiently.

Ballast Contamination Mechanisms
Ballasted railway tracks constitute the major transportation grids in many countries across the globe; they convey commuters, as well as freight and bulk cargoes, between cities, mines, farmlands, and ports . The railtrack structure can be categorised into two groups: the substructure and the superstructure. The substructure comprises the subgrade, the sub-ballast, and the ballast, while the superstructure encompasses the sleepers (timber or concrete), the fastening mechanism, and the steel rails.

Evolution of Digital Twins
A digital twin can be described as a digital replica of a real-world entity. It simulates the physical state and maybe the biological state and behavior of the real-world entity based on input data. It helps in predicting, optimizing, and improving decision making. It has revolutionized the industrial world, particularly the manufacturing industry, construction and healthcare sector, smart cities, and energy industry.
