Wife
A wife is a female partner in a continuing marital relationship. The term continues to be applied to a woman who has separated from her partner, and ceases to be applied to such a woman only when her marriage has come to an end, following a legally recognized divorce or the death of her spouse. On the death of her partner, a wife is referred to as a widow, but not after she is divorced from her partner. The rights and obligations of a wife in relation to her partner and her status in the community and in law vary between cultures and have varied over time.

Widow Conservation
Widow conservation was a practice in Protestant Europe in the early modern age, when the widow of a parish vicar (or sometimes her daughter) would marry her husband's successor to the vicarage to ensure her economic support. The practice was common in Scandinavia (Änkekonservering/Enkekonservering) and Protestant parts of Germany (Konservierung von Pfarrwitwen). It is related to other forms of widow inheritance, including the levirate marriage known in the Old Testament as yibbum. At the introduction of the Protestant Reformation, priests were allowed to marry. However, as they did not own the vicarage and property attached to their profession, their wife and children were left without a home and means of support after their death. The future support of the widows and children of vicars thereby became a concern for the various churches. The most common solution was for the successor of a vicar to be required to marry the widow (or perhaps her daughter) of his predecessor, thereby "conserving" her.

Widespread Zika Transmission
In 2016, a Zika virus outbreak in Brazil gained global prominence due to it coinciding with a sudden spike in birth abnormalities that was later attributed to pregnant women being infected with the virus. Today zika transmission patterns, particularly at sub-national levels, remain poorly described. Here we described evidence of widespread Zika transmission across the Philippines.

Wide-Bandgap Semiconductors for Radiation Detection
An overview of wide-bandgap (WBG) semiconductors for radiation detection applications is given. The recent advancements in the fabrication of high-quality wafers have enabled remarkable WBG semiconductor device applications. The most common 4H-SiC, GaN, and β-Ga2O3 devices used for radiation detection are described.

Wide-Bandgap Semiconductors Evaluation for High-Performance Domestic Induction Heating
In the induction heating system, the power transferred to the output depends on the equivalent resistance of the load, and the resistance depends on the operating frequency. Due to the switching characteristics of wide-bandgap power semiconductor devices, an induction heating system can be operated at higher operating frequencies.

Wide Structural Variety and Applications of Dendrimers
Dendrimers are hyper-branched macromolecules characterized by large numbers of end-group functionalities and a compact molecular structure. They consist of a central core molecule where multiple branches emerge, giving rise to a hierarchical and well-defined architecture.

Wide Local Excision in Primary Cutaneous Melanoma Management
Surgical wide local excision (WLE) is an elective procedure involving the excision of a larger area of tissue surrounding the scar left after diagnostic excision of a primary cutaneous melanoma. It remains the current standard of care for primary cutaneous melanoma and aims to achieve locoregional disease control with minimal functional and cosmetic impairment. Despite several prospective randomised trials, the optimal extent of excision margin remains controversial, and this is reflected in the persistent lack of consensus in guidelines globally.

Wide Field Infrared Survey Telescope
The Wide Field Infrared Survey Telescope (WFIRST) is a NASA infrared space observatory currently under development. WFIRST was recommended in 2010 by United States National Research Council Decadal Survey committee as the top priority for the next decade of astronomy. On February 17, 2016, WFIRST was approved for development and launch. WFIRST is based on an existing 2.4 m wide field-of-view telescope and will carry two scientific instruments. The Wide-Field Instrument is a 288-megapixel multi-band near-infrared camera, providing a sharpness of images comparable to that achieved by the Hubble Space Telescope (HST) over a 0.28 square degree field of view, 100 times larger than that of the HST. The Coronagraphic Instrument is a high-contrast, small field-of-view camera and spectrometer covering visible and near-infrared wavelengths using novel starlight-suppression technology. The design of WFIRST is based on one of the proposed designs for the Joint Dark Energy Mission between NASA and DOE. WFIRST adds some extra capabilities to the original JDEM proposal, including a search for extra-solar planets using gravitational microlensing. In its present incarnation (2015), a large fraction of its primary mission will be focused on probing the expansion history of the Universe and the growth of cosmic structure with multiple methods in overlapping redshift ranges, with the goal of precisely measuring the effects of dark energy, the consistency of general relativity, and the curvature of spacetime. On February 12, 2018, development on the WFIRST mission was proposed to be terminated in the President's FY19 budget request, due to a reduction in the overall NASA astrophysics budget and higher priorities elsewhere in the agency. However, in March 2018 Congress approved funding to continue making progress on WFIRST until at least September 30, 2018, in a bill stating that Congress "rejects the cancellation of scientific priorities recommended by the National Academy of Sciences decadal survey process".[needs update] In testimony before Congress in July 2018, NASA administrator Jim Bridenstine proposed slowing down the development of WFIRST in order to accommodate a cost increase in the James Webb Space Telescope (JWST), which would result in decreased[clarification needed] funding for WFIRST in 2020/2021. In the President's FY2020 budget request, termination of WFIRST was proposed again, due to cost overruns and higher priority for JWST.. The telescope received $511 million for FY2020.
