The Hero with a Thousand Faces
The Hero with a Thousand Faces (first published in 1949) is a work of comparative mythology by Joseph Campbell. In this book, Campbell discusses his theory of the mythological structure of the journey of the archetypal hero found in world myths. Since the publication of The Hero with a Thousand Faces, Campbell's theory has been consciously applied by a wide variety of modern writers and artists. Filmmaker George Lucas acknowledged Campbell's theory in mythology, and its influence on the Star Wars films. The Joseph Campbell Foundation and New World Library issued a new edition of The Hero with a Thousand Faces in July 2008 as part of the Collected Works of Joseph Campbell series of books, audio and video recordings. In 2011, Time (magazine) placed the book in its list of the 100 best and most influential books written in English since the magazine was founded in 1923.

Electric Vehicles Charging/Discharging and Battery Degradation
The high penetration of electric vehicles (EVs) will burden the existing power delivery infrastructure if their charging and discharging are not adequately coordinated. The degradation of lithium-ion batteries occurs throughout their lives due to several chemicals and mechanical processes that reduce the cyclable lithium and other active materials. Battery degradation depends on many factors, such as the charging and discharging rates, depth of discharge (DOD), temperature, voltage, cycle number, and storage stage of charge.

Primal Therapy
Primal therapy is a trauma-based psychotherapy created by Arthur Janov, who argues that neurosis is caused by the repressed pain of childhood trauma. Janov argues that repressed pain can be sequentially brought to conscious awareness and resolved through re-experiencing specific incidents and fully expressing the resulting pain during therapy. In therapy, the patient recalls and reenacts a particularly disturbing past experience usually occurring early in life and expresses normally repressed anger or frustration especially through spontaneous and unrestrained screams, hysteria, or violence. Primal therapy was developed as a means of eliciting the repressed pain; the term Pain is capitalized in discussions of primal therapy when referring to any repressed emotional distress and its purported long-lasting psychological effects. Janov criticizes the talking therapies as they deal primarily with the cerebral cortex and higher-reasoning areas and do not access the source of Pain within the more basic parts of the central nervous system. Primal therapy is used to re-experience childhood pain—i.e., felt rather than conceptual memories—in an attempt to resolve the pain through complete processing and integration, becoming real. An intended objective of the therapy is to lessen or eliminate the hold early trauma exerts on adult behaviour. Primal therapy became very influential during a brief period in the early 1970s, after the publication of Janov's first book, The Primal Scream. It inspired hundreds of spin-off clinics worldwide and served as an inspiration for many popular cultural icons. Singer-songwriter John Lennon, actor James Earl Jones, and pianist Roger Williams were prominent advocates of primal therapy. Primal therapy has since declined in popularity, partly because Janov had not demonstrated in research the outcomes necessary to convince research-oriented psychotherapists of its effectiveness. Proponents of the methodology continue to advocate and practice the therapy or variations of it.

NTC-Properties of a Geomorphic Clinoptilolite Sample
Negative temperature coefficient (NTC) materials are usually based on ceramic semiconductors, and electrons are involved in their transport mechanism. A new type of NTC material, adequate for alternating current (AC) applications, is represented by zeolites. Indeed, zeolites are single charge carrier ionic conductors with a temperature-dependent electrical conductivity. In particular, electrical transport in zeolites is due to the monovalent charge-balancing cations, like K+, capable of hopping between negatively charged sites in the aluminosilicate framework. Owing to the highly non-linear electrical behavior of the traditional electronic NTC materials, the possibility to have alternative types of materials, showing linearity in their electrical behavior, is very desirable. Among different zeolites, natural clinoptilolite has been selected for investigating NTC behavior since it is characterized by high zeolite content, a convenient Si/Al atomic ratio, good mechanical strength due to its compact microstructure, and low toxicity. Clinoptilolite has shown a rapid and quite reversible impedance change under heating, characterized by a linear dependence on temperature.

Bessel Beam
Diffraction is a phenomenon related to the wave nature of light and arises when a propagating wave comes across an obstacle. Consequently, the wave can be transformed in amplitude or phase and diffraction occurs. Those parts of the wavefront avoiding an obstacle form a diffraction pattern after interfering with each other. In this review paper, we have discussed the topic of non-diffractive beams, explicitly Bessel beams. Such beams provide some resistance to diffraction and hence are hypothetically a phenomenal alternate to Gaussian beams in several circumstances. Several outstanding applications are coined to Bessel beams and have been employed in commercial applications. We have discussed several hot applications based on these magnificent beams such as optical trapping, material processing, free-space long-distance self-healing beams, optical coherence tomography, superresolution, sharp focusing, polarization transformation, increased depth of focus, birefringence detection based on astigmatic transformed BB and encryption in optical communication. According to our knowledge, each topic presented in this entry is justifiably explained.

Extracellular Matrix and Its Artificial Substitutes
The existence of orderly structures such as tissues and organs is made possible by cell adhesion, i.e. the process by which cells attach to neighbouring cells and a supporting substance in the form of the extracellular matrix. The extracellular matrix is a three-dimensional structure composed of collagens, elastin and various proteoglycans and glycoproteins. It is a storehouse for multiple signalling factors. Tissue disruption often prevents the natural reconstitution of the matrix. The use of appropriate implants is then required. The possibilities of regenerating damaged tissues using an artificial matrix substitute are described, detailing the host response to the implant. An important issue is the surface properties of such an implant and the possibilities of their modification.

Outline of Transhumanism
The following outline provides an overview of and a topical guide to transhumanism, an international intellectual and cultural movement that affirms the possibility and desirability of fundamentally transforming the human condition by developing and making widely available technologies to eliminate aging and to greatly enhance human intellectual, physical and psychological capacities. Transhumanist thinkers study the potential benefits and dangers of emerging and hypothetical technologies that could overcome fundamental human limitations as well as study the ethical matters involved in developing and using such technologies. They predict that human beings may eventually be able to transform themselves into beings with such greatly expanded abilities as to merit the label posthuman.

Xanthine Oxidoreductase Activities
Xanthine oxidoreductase (XOR) is the enzyme that catalyzes the oxidation of hypoxanthine to xanthine and xanthine to uric acid. XOR is widely distributed throughout living organisms and is highly conserved in prokaryotic, plant, and animal species. XOR activity is very versatile, generating both pro-oxidant (primarily within the cell) and anti-oxidant (primarily in plasma) products.

Porifera
Sponges, the members of the phylum Porifera (/pəˈrɪfərə/; meaning 'pore bearer'), are a basal animal clade as a sister of the Diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells. Sponges have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohyl in the process. Sponges do not have nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes. Sponges were first to branch off the evolutionary tree from the last common ancestor of all animals, making them the sister group of all other animals.

Objectivity
In philosophy, objectivity is the concept of truth independent from individual subjectivity (bias caused by one's perception, emotions, or imagination). A proposition is considered to have objective truth when its truth conditions are met without bias caused by the mind of a sentient being. Scientific objectivity refers to the ability to judge without partiality or external influence. Objectivity in the moral framework calls for moral codes to be assessed based on the well-being of the people in the society that follow it. Moral objectivity also calls for moral codes to be compared to one another through a set of universal facts and not through subjectivity.

WannaCry Ransomware Attack
The WannaCry ransomware attack was a worldwide cyberattack in May 2017 by the WannaCry ransomware cryptoworm, which targeted computers running the Microsoft Windows operating system by encrypting data and demanding ransom payments in the Bitcoin cryptocurrency. It propagated through EternalBlue, an exploit developed by the United States National Security Agency (NSA) for older Windows systems. EternalBlue was stolen and leaked by a group called The Shadow Brokers a month prior to the attack. While Microsoft had released patches previously to close the exploit, much of WannaCry's spread was from organizations that had not applied these, or were using older Windows systems that were past their end-of-life. These patches were imperative to organizations' cyber security but many were not implemented due to ignorance of their importance. Some have claimed a need for 24/7 operation, aversion to risking having formerly working applications breaking because of patch changes, lack of personnel or time to install them, or other reasons. The attack began at 07:44 UTC on 12 May 2017 and was halted a few hours later at 15:03 UTC by the registration of a kill switch discovered by Marcus Hutchins. The kill switch prevented already infected computers from being encrypted or further spreading WannaCry. The attack was estimated to have affected more than 200,000 computers across 150 countries, with total damages ranging from hundreds of millions to billions of United States dollar . Security experts believed from preliminary evaluation of the worm that the attack originated from North Korea or agencies working for the country. In December 2017, the United States and United Kingdom formally asserted that North Korea was behind the attack. A new variant of WannaCry forced Taiwan Semiconductor Manufacturing Company (TSMC) to temporarily shut down several of its chip-fabrication factories in August 2018. The virus spread to 10,000 machines in TSMC's most advanced facilities.

Pathophysiology and Classification of Disc Herniation
Low-back pain (LBP) is a broad category of musculoskeletal disorders regarded as one of the primary causes of disability in the general population, with a lifetime incidence of 65–85% of individuals worldwide. One of the specific causes of LBP is lumbar intervertebral disc disorders with nerve root irritation. Most individuals affected fall within the age range of 30 to 50 years, with a higher prevalence in men than in women. The intervertebral disc is formed by an inner nucleus pulposus (NP), an outer annulus fibrosus (AF), and the cartilaginous endplates that attach the disc to its vertebrae. The protrusion of disc material into the spinal canal from outside the annular lining is known as herniation. When compared to other regions, the lumbar region is where disc herniation is most commonly observed, especially at the L4-L5 and L5-S1 levels. Lumbar disc herniation associated with radiculopathy (LDHR) is the outcome of the extruded disc material pressing into or contacting the lumbar nerve roots.

Dog-Whistle Politics
Dog-whistle politics is the use of coded or suggestive language in politics to garner support from a wider audience for a candidate. Dog whistles serve the purpose of attracting the intended political audience without garnering ire with opposing audiences, similar to ultrasonic dog whistles used in sheepherding. The concept of dog-whistles has similarities to the concept of code words. Accusations of dog-whistling may be used to accuse an individual of expressing a "hidden" meaning when no such message was intended and the actual words used are innocuous. Such accusations can be a form of political correctness or gaslighting and are by their nature impossible to refute. An example is the accusation that using the phrase "international banks" is evidence of anti-Semitism. When it exists, a dog-whistle is a type of doublespeak used in political messaging. Dog whistles work by employing language that has normal meanings to the majority, but can be implied or loaded to mean very specific things to intended recipients. One example commonly believed to be dog whistling may include is the use of 'family values' as a signal to Christians that the candidate is Christian and would support policies related to Christian values without raising flags among the non-religious who might oppose a Christian candidate. This type of dog whistle would serve the purpose of gaining popularity with Christians without losing popularity with non-Christians.
