Functional Neurologic Disorder
A functional neurological disorder (FND) is a condition in which patients experience neurological symptoms such as weakness, movement disorders, sensory symptoms and blackouts. Symptoms of functional neurological disorders are clinically recognisable, but are not categorically associated with a definable organic disease. The intended contrast is with an organic brain syndrome, where a physiological cause can be indentified. Subsets of functional neurological disorders include functional neurological symptom disorder (FNsD), conversion disorder, and psychogenic movement disorder/non-epileptic seizures. Neurological symptoms which are unexplained by organic disease are common in neurological services, accounting for up to one third of outpatient neurology clinic attendances, and associated with as much self-reported disability and distress as those caused by organic neurological disorders. The diagnosis is made based on positive signs and symptoms in the history and examination during consultation of a neurologist (see below). Physiotherapy is particularly helpful for patients with motor symptoms (weakness, gait disorders, movement disorders) and tailored cognitive behavioural therapy has the best evidence in patients with dissociative (non-epileptic) attacks.

Vintage Car
A vintage car is, in the most general sense, an old automobile, and in the narrower senses of car enthusiasts and collectors, it is a car from the period of 1919 to 1930. Such enthusiasts have categorization schemes for ages of cars that enforce distinctions between antique cars, vintage cars, classic cars, and so on. The classification criteria vary, but consensus within any country is often maintained by major car clubs.

Interactive Movie
An interactive movie, also known as a movie game, is a video game that presents its gameplay in a cinematic, scripted manner, often through the use of full-motion video of either animated or live-action footage. In modern times, the term also refers to games that have a larger emphasis on story/presentation than on gameplay, often used in a pejorative way.

Anomaly
In quantum physics an anomaly or quantum anomaly is the failure of a symmetry of a theory's classical action to be a symmetry of any regularization of the full quantum theory. In classical physics, a classical anomaly is the failure of a symmetry to be restored in the limit in which the symmetry-breaking parameter goes to zero. Perhaps the first known anomaly was the dissipative anomaly in turbulence: time-reversibility remains broken (and energy dissipation rate finite) at the limit of vanishing viscosity. In quantum theory, the first anomaly discovered was the Adler–Bell–Jackiw anomaly, wherein the axial vector current is conserved as a classical symmetry of electrodynamics, but is broken by the quantized theory. The relationship of this anomaly to the Atiyah–Singer index theorem was one of the celebrated achievements of the theory. Technically, an anomalous symmetry in a quantum theory is a symmetry of the action, but not of the measure, and so not of the partition function as a whole.

Humanitarian Logistics
Although logistics has been mostly utilized in commercial supply chains, it is also an important tool in disaster relief operations. Humanitarian logistics is a branch of logistics which specializes in organizing the delivery and warehousing of supplies during natural disasters or complex emergencies to the affected area and people. However, this definition focuses only on the physical flow of goods to final destinations, and in reality, humanitarian logistics is far more complicated and includes forecasting and optimizing resources, managing inventory, and exchanging information. Thus, a good broader definition of humanitarian logistics is the process of planning, implementing and controlling the efficient, cost-effective flow and storage of goods and materials, as well as related information, from the point of origin to the point of consumption for the purpose of alleviating the suffering of vulnerable people. This figure presents numerous important aspects in humanitarian logistics, including transport, inventory management, infrastructure, and communications.

Exercise Induced Anaphylaxis
Exercise-Induced Anaphylaxis (EIAn) is a rare condition in which anaphylaxis, a serious or life-threatening allergic response, is brought on by physical activity. Approximately 5-15% of all reported cases of anaphylaxis are thought to be exercise-induced. The exact proportion of the population with EIAn is unknown, but a 2001 study of 76,229 Japanese junior high students showed that the frequency of EIAn was 0.031%. EIAn is not a widely known or understood condition, with the first research on the disorder only having been conducted in the past 40 years. A case report in 1979 on EIAn was the first research of its kind, where a patient was described to experience anaphylactic shock related to exercise 5–24 hours following the consumption of shellfish. The condition is thought to be more prevalent in women, with two studies of EIAn patients reporting a ratio of 2:1 for females:males with the disorder. There is, however, thought to be no link to race. Survey results from EIAn patients have shown that the average number of attacks per year is 14.5. However, most sufferers of EIAn report that both severity and frequency of attacks decrease over time.

EINTR
The Unix philosophy, originated by Ken Thompson, is a set of cultural norms and philosophical approaches to minimalist, modular software development. It is based on the experience of leading developers of the Unix operating system. Early Unix developers were important in bringing the concepts of modularity and reusability into software engineering practice, spawning a "software tools" movement. Over time, the leading developers of Unix (and programs that ran on it) established a set of cultural norms for developing software; these norms became as important and influential as the technology of Unix itself, and have been termed the "Unix philosophy." The Unix philosophy emphasizes building simple, compact, clear, modular, and extensible code that can be easily maintained and repurposed by developers other than its creators. The Unix philosophy favors composability as opposed to monolithic design.

Dialysis (Biochemistry)
In biochemistry, dialysis is the process of separating molecules in solution by the difference in their rates of diffusion through a semipermeable membrane, such as dialysis tubing. Dialysis is a common laboratory technique that operates on the same principle as medical dialysis. In the context of life science research, the most common application of dialysis is for the removal of unwanted small molecules such as salts, reducing agents, or dyes from larger macromolecules such as proteins, DNA, or polysaccharides. Dialysis is also commonly used for buffer exchange and drug binding studies. The concept of dialysis was introduced in 1861 by the Scottish chemist Thomas Graham. He used this technique to separate sucrose (small molecule) and gum Arabic solutes (large molecule) in aqueous solution. He called the diffusible solutes crystalloids and those that would not pass the membrane colloids. From this concept dialysis can be defined as a spontaneous separation process of suspended colloidal particles from dissolved ions or molecules of small dimensions through a semi permeable membrane. Most common dialysis membrane are made of cellulose, modified cellulose or synthetic polymer (cellulose acetate or nitrocellulose).
