Time Synchronization
Time (or clock) synchronization is a large and vital field of research, as synchronization is a precondition for many applications. A few example applications are distributed data acquisition, distributed databases, and real-time communication.

Food Heritage
The entry explores the concept of food heritage, focusing mainly on the anthropological, geographical, and sociological debate. Although the review identifies some conceptualisations that frame heritage in the food and gastronomic domains, it also shows the high degree of fragmentation of the debate. In so doing, it sheds light on how the concept of food heritage from a theoretical point of view is still in progress.

State Within a State
A state within a state or a deep state is a political situation in a country when an internal organ, such as the armed forces or public authorities (intelligence agencies, police, secret police, administrative agencies, and branches of government bureaucracy), does not respond to the civilian political leadership. Although the state within a state can be conspiratorial in nature, the deep state can also take the form of entrenched unelected career civil servants acting in a non-conspiratorial manner, to further their own interests (e.g. continuity of the state as distinct from the administration, job security, enhanced power and authority, pursuit of ideological goals and objectives, and the general growth of their agency) and in opposition to the policies of elected officials, by obstructing, resisting, and subverting the policies, conditions and directives of elected officials. The term, like many in politics, derives from the Greek language (κράτος εν κράτει, kratos en kratei, later adopted into Latin as imperium in imperio or status in statu). Sometimes the term refers to state companies that, though formally under the command of the government, act 'de facto' like private corporations. Sometimes the term refers to companies that, though formally private, act de facto like "states within a state". Political debate surrounding the separation of church and state previously revolved around the perception that if left unchecked the Church might turn into a kind of State within a State, an illegitimate outgrowth of the State's natural civil power. In the field of political science, this pop culture concept is studied within the literature on the state. Current literature on the state generally traces a lineage to Bringing the State Back In (1985) and remains an active body of scholarly research to this day. Within this literature, the state is understood as both venue (a set of rules under which others act and interact) as well as actor (with its own agenda). An example of a non-conspiratorial version of the 'state as actor' from the empirical scholarly literature would be "doing truth to power" (as a play on speaking truth to power, which is what journalists often aspire to do) as studied by Todd La Porte. Under this dual understanding, the conspiratorial version of the deep state concept would be one version of the 'state as actor' while the non-conspiratorial version would be another version of the 'state as venue.' The fundamental takeaway from the scholarly literature on the dual nature of the state is that the 'state as actor' (deep state) is a characteristic of all states which can have both good and bad effects and should not be seen as bad by default.

Successive Approximation ADC
A successive approximation ADC is a type of analog-to-digital converter that converts a continuous analog waveform into a discrete digital representation via a binary search through all possible quantization levels before finally converging upon a digital output for each conversion.

Virus Elimination in Plants
Virus elimination from plants is mostly based on the in vitro culture of isolated meristem, and in addition thermotherapy, chemotherapy, electrotherapy, and cryotherapy can also be applied. Treatments can result in low rate of survival, inhibited growth, incomplete development, or abnormal morphology.  The rate of destruction depends on the genotypes and physiological condition of plants. There are several ways to decrease the harmful effect of treatments.

Ge'ez
Ge'ez (/ˈɡiːɛz/; ግዕዝ, Gəʿəz Template:IPA-gez; also transliterated Gi'iz) is an ancient South Semitic language of the Ethiosemitic branch. The language originates from the region encompassing northern Ethiopia and southern Eritrea in the Horn of Africa. Today, Ge'ez is used only as the main language of liturgy of the Ethiopian Orthodox Tewahedo and Eritrean Orthodox Tewahedo churches, the Ethiopian and Eritrean Catholic churches, and the Beta Israel Jewish community. However, in Ethiopia, Amharic or other local languages, and in Eritrea and Ethiopia's Tigray Region, Tigrinya may be used for sermons. Amharic, Tigrinya, and Tigre are closely related to Ge'ez. The closest living languages to Ge'ez are Tigre and Tigrinya with lexical similarity at 71% and 68%, respectively. Some linguists do not believe that Ge'ez constitutes a common ancestor of modern Ethiosemitic languages, but that Ge'ez became a separate language early on from another hypothetical unattested language, which can be seen as an extinct sister language of Amharic, Tigre and Tigrinya. The foremost Ethiopian experts such as Amsalu Aklilu point to the vast proportion of inherited nouns that are unchanged, and even spelled identically in both Ge'ez and Amharic (and to a lesser degree, Tigrinya).

Cultural Memory
Historic urban landscapes (HULs) are composed of layers of imbedded tangible and intangible features such as cultural memories. As the collective memories of city inhabitants, cultural memories can affect elements of social sustainability such as health, well-being, community identity, place perception and social engagement. This topic review points to the value of recalling cultural memory features in HULs, which can be used to achieve social sustainability.  In addition, it contributes to sustainable development through the contribution of cultural memory and its influence on the formation of place identity, sense of place, civic pride and quality of life in HULs.

The Pathogenesis of Epilepsy
Epilepsy is a chronic neurological disorder characterized by recurring spontaneous seizures. Drug resistance appears in 30% of patients and it can lead to premature death, brain damage or a reduced quality of life. The purpose of the study was to analyze the drug resistance mechanisms, especially neuroinflammation, in the epileptogenesis. The information bases of biomedical literature Scopus, PubMed, Google Scholar and SciVerse were used. To obtain full-text documents, electronic resources of PubMed Central and Research Gate were used. The article examines the recent research of the mechanisms of drug resistance in epilepsy and discusses the hypotheses of drug resistance development (genetic, epigenetic, target hypothesis, etc.). Drug-resistant epilepsy is associated with neuroinflammatory, autoimmune and neurodegenerative processes. Neuroinflammation causes immune, pathophysiological, biochemical and psychological consequences. Focal or systemic unregulated inflammatory processes lead to the formation of aberrant neural connections and hyperexcitable neural networks. Inflammatory mediators affect the endothelium of cerebral vessels, destroy contacts between endothelial cells and induce abnormal angiogenesis (the formation of “leaky” vessels), thereby affecting the blood–brain barrier permeability. Thus, the analysis of pro-inflammatory and other components of epileptogenesis can contribute to the further development of the therapeutic treatment of drug-resistant epilepsy.
