Entoptic Phenomenon
Entoptic phenomena (from grc ἐντός (entós) 'within', and ὀπτικός (optikós) 'visual') are visual effects whose source is within the human eye itself. (Occasionally, these are called entopic phenomena, which is probably a typographical mistake.) In Helmholtz's words: "Under suitable conditions light falling on the eye may render visible certain objects within the eye itself. These perceptions are called entoptical."

Hattendorf's Theorem
Hattendorff's Theorem, attributed to K. Hattendorff (1868), is a theorem in actuarial science that describes the allocation of the variance or risk of the loss random variable over the lifetime of an actuarial reserve. In other words, Hattendorff's theorem demonstrates that the variation in the present value of the loss of an issued insurance policy can be allocated to the future years during which the insured is still alive. This, in turn, facilitates the management of risk prevalent in such insurance contracts over short periods of time.

Special Prosecutor
In the United States, a special counsel (formerly called special prosecutor or independent counsel) is a lawyer appointed to investigate, and potentially prosecute, a particular case of suspected wrongdoing for which a conflict of interest exists for the usual prosecuting authority. Other jurisdictions have similar systems. For example, the investigation of an allegation against a sitting president or attorney general might be handled by a special prosecutor rather than by an ordinary prosecutor who would otherwise be in the position of investigating their own superior. Investigations into other persons connected to the government but not in a position of direct authority over the prosecutor, such as cabinet secretaries or election campaigns, have also been handled by special prosecutors. While the most prominent special prosecutors have been those appointed since the 1870s to investigate presidents and those connected to them, the term can also be used to refer to any prosecutor appointed to avoid a conflict of interest or appearance thereof. The concept originates in state law: "state courts have traditionally appointed special prosecutors when the regular government attorney was disqualified from a case, whether for incapacitation or interest." Because district attorneys' offices work closely with police, some activists argue that cases of police misconduct at the state and local level should be handled by special prosecutors.

Multielectrode Array
Multielectrode arrays (MEAs) or microelectrode arrays are devices that contain multiple plates or shanks through which neural signals are obtained or delivered, essentially serving as neural interfaces that connect neurons to electronic circuitry. There are two general classes of MEAs: implantable MEAs, used in vivo, and non-implantable MEAs, used in vitro.

Sina Weibo
Sina Weibo (NASDAQ: WB) (新浪微博) is a Chinese microblogging (weibo) website. Launched by Sina Corporation on 14 August 2009, it is one of the biggest social media platforms in China, with over 445 million monthly active users as of Q3 2018. The platform has been a huge financial success, with surging stocks, lucrative advertising sales and high revenue and total earnings per quarter. At the start of 2018, it surpassed the US$30 billion market valuation mark for the first time. In March 2014, Sina Corporation announced a spinoff of Weibo as a separate entity and filed an IPO under the symbol WB. Sina carved out 11% of Weibo in the IPO, with Alibaba owning 32% post-IPO. The company began trading publicly on 17 April 2014. In March 2017, Sina launched Sina Weibo International Version. This new version has a clean, concise user interface design, as well as an ad-free feature; while its volume is very small, only occupying one-fifth of the space of the original, it still performs all of the original's functions. In June 2018, Sina Weibo reached 413 million active users. In November 2018, Sina Weibo suspended its registration function for minors under the age of 14. In July 2019, Sina Weibo announced that it would launch a two-month campaign to clean up pornographic and vulgar information, named The Blue Plan. Sina Weibo has attracted criticism over censoring its users.

Inventory (Museum)
An inventory is an itemized list of objects that the museum has accessioned or received via loan(s) and must be physically located by an examiner. A complete, one-hundred percent inventory, or a random inventory of the collection must be carried out periodically to ensure the museum is operating under best practices and for security purposes. The museum is legally responsible and ethically obligated for the maintenance of up-to-date information detailing the location of all objects within the collection, including loaned items and objects that have yet to be accessioned; this is stipulated by many museum associations, including the American Association of Museums.

Adhesive Capsulitis of Shoulder
Adhesive capsulitis, also known as a frozen shoulder, is a painful and disabling disorder of unclear cause in which the shoulder capsule, the connective tissue surrounding the glenohumeral joint of the shoulder, becomes inflamed and stiff, greatly restricting motion and causing pain. Pain is usually constant, worse at night, and with cold weather. Certain movements or bumps can provoke episodes of increased pain. People who have adhesive capsulitis usually experience pain and sleep deprivation for prolonged periods due to pain that gets worse when lying still and restricted movement. The condition can lead to depression, problems in the neck and back, and weight loss due to long-term lack of deep sleep. People who have adhesive capsulitis may have difficulty concentrating, working, or performing daily life activities for extended periods of time. The condition tends to be self-limiting and usually resolves over time without surgery. Most people regain about 90% of shoulder motion over time. The condition is thought to be caused by injury or trauma to the area and may have an autoimmune component. Risk factors for frozen shoulder include tonic seizures, diabetes mellitus, stroke, accidents, lung disease, connective tissue diseases, thyroid disease, and heart disease. It is more prevalent in people 40–65 years of age, and in females. Treatment may be painful and taxing and consists of physical therapy, occupational therapy, medication, massage therapy, hydrodilatation or surgery. A physician may also perform manipulation under anesthesia, which breaks up the adhesions and scar tissue in the joint to help restore some range of motion. Alternative treatments exist such as the Trigenics OAT Procedure, ART, and the OTZ method. But these can vary in efficacy depending on the type and severity of the frozen shoulder. Pain and inflammation can be controlled with pain medications such as NSAIDs. Steroid injection alone is only of short term benefit in improving pain.
