Epigenetics of Anxiety and Stress-Related Disorders
Epigenetics of anxiety and stress-related disorders is the field studying the relationship between epigenetic modifications of genes and anxiety and stress-related disorders, including mental health disorders such as generalized anxiety disorder (GAD), post-traumatic stress disorder, obsessive-compulsive disorder (OCD), and more. Epigenetic modifications play a role in the development and heritability of these disorders and related symptoms. For example, regulation of the hypothalamus-pituitary-adrenal axis by glucocorticoids plays a major role in stress response and is known to be epigenetically regulated. As of 2015 most work has been done in animal models in laboratories, and little work has been done in humans; the work is not yet applicable to clinical psychiatry.

Adaptability Quotient
Adaptability Quotient (AQ) is a metric of adaptability used to measure performance in the workplace and assess individual potential. The earliest article published by Stuart Parkin in 2010 gave rise to the term Adaptability Quotient. This has inspired many others to expand and research the area. A recent deep dive into Adaptability Quotient can be found at SingularityU London Adaptability Webinar: "Developing adaptable workforces, a roadmap to recovery", where Ross Thornley, is joined by Jason Slater from UNIDO and Professor Nicolas Deuschel . Additionally Amin Toufani in 2014, shares his insights during his public lecture at Singularity University. he defines AQ as the ability to realize optimal outcomes based on recent or future change. Ross Thornley and Mike Raven's work at AQai is deepening the scientific research of AQ in the workplace, opening up new frontiers of understanding and links across multiple disciplines. Their A.C.E model is widely seen as the most holistic and comprehensive assessment. AQ is defined as, "Measuring the abilities, characteristics, and environmental factors which impact the successful behaviors and actions of people, and organizations to effectively respond to uncertainty, new information, or changed circumstances.” Decoding AQ 2020, Ross Thornley. (As of 2019), there is a growing body of literature surrounding adaptability, and consequent interest in being able to harness, measure, and quantify adaptability in the workplace. Adaptability was identified as the “new competitive advantage” by the Harvard Business Review in 2011. In 2014, The Flux Report (published by Right Management in the UK) revealed that 91% of HR managers thought that: "People will be recruited on their ability to deal with change and uncertainty" as opposed to other skills. Specifically adaptive performance in the research literature means numerous organizational scholars have recognized that traditional models of performance are static and need to be augmented to include "responsiveness to changing job requirements" — labeled adaptive performance (AP; Allworth & Hesketh, 1999, p. 98; Griffin, Neal, & Parker, 2007; Pulakos, Arad, Donovan, & Plamondon, 2000).

Antenatal Depression
Antenatal depression, also known as prenatal or perinatal depression, is a form of clinical depression that can affect a woman during pregnancy, and can be a precursor to postpartum depression if not properly treated. It is estimated that 7% to 20% of pregnant women are affected by this condition. Any form of prenatal stress felt by the mother can have negative effects on various aspects of fetal development, which can cause harm to the mother and child. Even after birth, a child born from a depressed or stressed mother feels the affects. The child is less active and can also suffer from emotional distress. Antenatal depression can be caused by the stress and worry that pregnancy can bring, but at a more severe level. Other triggers include unplanned pregnancy, difficulty becoming pregnant, history of abuse, and economic or family situations. Commonly, symptoms involve how the patient views herself, how she feels about going through such a life changing event, the restrictions on the mother's lifestyle that motherhood will place, or how the partner or family feel about the baby. Pregnancy places significant strain on a woman's body, so stress, mood swings, sadness, irritability, pain, and memory changes are to be expected. Left untreated, antenatal depression can be extremely dangerous for the health of the mother and the baby. It is highly recommended that mothers who feel they are experiencing antenatal depression have a discussion about it with their health care provider. Mothers with a history of mental health issues should also talk to their doctor about it early in the pregnancy to help with possible depressive symptoms.

INTERLNK
This article presents a list of commands used by DOS operating systems, especially as used on x86-based IBM PC compatibles (PCs). Other DOS operating systems are not part of the scope of this list. In DOS, many standard system commands were provided for common tasks such as listing files on a disk or moving files. Some commands were built into the command interpreter, others existed as external commands on disk. Over the several generations of DOS, commands were added for the additional functions of the operating system. In the current Microsoft Windows operating system, a text-mode command prompt window, cmd.exe, can still be used.

Chalk
Chalk is a soft, white, porous, sedimentary carbonate rock, a form of limestone composed of the mineral calcite. Calcite is an ionic salt called calcium carbonate or CaCO3. It forms under reasonably deep marine conditions from the gradual accumulation of minute calcite shells (coccoliths) shed from micro-organisms called coccolithophores. Flint (a type of chert) is very common as bands parallel to the bedding or as nodules embedded in chalk. It is probably derived from sponge spicules or other siliceous organisms as water is expelled upwards during compaction. Flint is often deposited around larger fossils such as Echinoidea which may be silicified (i.e. replaced molecule by molecule by flint). Chalk, as seen in Cretaceous deposits of Western Europe, is unusual among sedimentary limestones in the thickness of the beds. Most cliffs of chalk have very few obvious bedding planes unlike most thick sequences of limestone such as the Carboniferous Limestone or the Jurassic oolitic limestones. This may indicate very stable conditions over tens of millions of years. Chalk has greater resistance to weathering and slumping than the clays with which it is usually associated, thus forming tall, steep cliffs where chalk ridges meet the sea. Chalk hills, known as chalk downland, usually form where bands of chalk reach the surface at an angle, so forming a scarp slope. Because chalk is well jointed it can hold a large volume of ground water, providing a natural reservoir that releases water slowly through dry seasons.
