The never type represents the type of values that never occur.For instance, never is the return type for a function expression or an arrow function expression that always throws an exception or one that never returns.Variables also acquire the type never when narrowed by any type guards that can never be true.
It can be tempting to think that the types Number, String, Boolean, Symbol, or Object are the same as the lowercase versions recommended above.These types do not refer to the language primitives however, and almost never should be used as a type.
Netscape 6.0 is finally going into its first public beta. There never was a version 5.0. The last major release, version 4.0, was released almost three years ago. Three years is an awfully long time in the Internet world. During this time, Netscape sat by, helplessly, as their market share plummeted.
Although the let is pointless here, it illustrates the meaning of !. Since x is neverassigned a value (because return returns from the entire function), x can be given type!. We could also replace return 123 with a panic! or a never-ending loop and this codewould still be valid.
When implementing this trait for String we need to pick a type for Err. And sinceconverting a string into a string will never result in an error, the appropriate type is !.(Currently the type actually used is an enum with no variants, though this is only because !was added to Rust at a later date and it may change in the future.) With an Err type of!, if we have to call String::from_str for some reason the result will be aResult which we can unpack like this:
Never Events are also being publicly reported, with the goal of increasing accountability and improving the quality of care. Since the NQF disseminated its original Never Events list in 2002, 11 states have mandated reporting of these incidents whenever they occur, and an additional 16 states mandate reporting of serious adverse events (including many of the NQF Never Events). Health care facilities are accountable for correcting systematic problems that contributed to the event, with some states (such as Minnesota) mandating performance of a root cause analysis and reporting its results.
Methods: We examined the extent to which head and neck cancer is associated with cigarette smoking among never drinkers and with alcohol drinking among never users of tobacco. We pooled individual-level data from 15 case-control studies that included 10,244 head and neck cancer case subjects and 15,227 control subjects, of whom 1072 case subjects and 5775 control subjects were never users of tobacco and 1598 case subjects and 4051 control subjects were never drinkers of alcohol. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using unconditional logistic regression models. All statistical tests were two-sided.
Results: Among never drinkers, cigarette smoking was associated with an increased risk of head and neck cancer (OR for ever versus never smoking = 2.13, 95% CI = 1.52 to 2.98), and there were clear dose-response relationships for the frequency, duration, and number of pack-years of cigarette smoking. Approximately 24% (95% CI = 16% to 31%) of head and neck cancer cases among nondrinkers in this study would have been prevented if these individuals had not smoked cigarettes. Among never users of tobacco, alcohol consumption was associated with an increased risk of head and neck cancer only when alcohol was consumed at high frequency (OR for three or more drinks per day versus never drinking = 2.04, 95% CI = 1.29 to 3.21). The association with high-frequency alcohol intake was limited to cancers of the oropharynx/hypopharynx and larynx.
A U.S. citizen who has never resided in the U.S., who has not previously registered to vote in another state, and whose parent or legal guardian was a California resident when they were last living in the U.S., is eligible to vote in California.
In the United States, about 10% to 20% of lung cancers, or 20,000 to 40,000 lung cancers each year, happen in people who never smoked or smoked fewer than 100 cigarettes in their lifetime. Researchers estimate that secondhand smoke contributes to about 7,300 and radon to about 2,900 of these lung cancers.
A laptop pack that grows, the Expandable backpack is a carry-on dream come true. Quick access external pockets and a gusseted main compartment zipper with securing hooks mean you can both grab and stuff very quickly, while front pocket organization helps restore calm. Padded shoulder straps and back panel make airport sprints almost comfortable, and weatherproof zippers keep rain and ever-threatening liquids out. And all of this in a tasteful package; premium materials and contemporary coloring belie the Expandable's supreme functionality. Always wear it, never check it.
"Wow in a legal proceeding Trump is now arguing he didn't violate the 14th Amendment by inciting the Jan 6 insurrection because he 'never took an oath to support the Constitution of the United States.' This treacherous criminal is head of the Republican Party," Democratic New Jersey Congressman Bill Pascrell posted on X, formerly Twitter.
"Because the framers chose to define the group of people subject to Section Three by an oath to 'support' the Constitution of the United States, and not by an oath to 'preserve, protect and defend' the Constitution, the framers of the Fourteenth Amendment never intended for it to apply to the President," Blue wrote.
In 2007, The Leapfrog Hospital Survey began asking hospitals about their process for handling serious reportable events. Since Leapfrog declared these principles as our standard, new research and experience have further informed evidence on best practices for addressing never events. In particular, AHRQ developed, tested, and launched the CANDOR Toolkit, and the National Patient Safety Foundation gathered stakeholders to propose new approaches to performing root cause analysis. As a result, Leapfrog has added four additional principles to its policy statement beginning in 2017, to further ensure that patients and families, as well as caregivers, receive appropriate follow-up if a never event occurs. A hospital "fully meets standards" if they agree to all of the following if a Never Event occurs within their facility:
The documentary suggests he had a troubled childhood and genuinely hoped to make the show into a success. "He is a damaged person who's had a tough life," Francis-Roy says. "He's now able to look back and it's complicated for him. It's still not easy for him to process." Dalton says he had "everything except the contacts" to make the show a reality, while even the contestants think he had the makings of a great TV producer. Two decades on, he seems scarred by what happened and haunted by guilt. But it's never fully clear whether he's genuinely sorry for his actions, or merely sorry for his own downfall.
Composer allows the end-user to build custom, automated investment strategies, all without writing a line of code. Composer is flexible enough that it is intended to allow the user to create strategies that the founding team never anticipated. Before Composer, a strategy creator would need to be fluent in Python or a similar language to harness this degree of flexibility, severely limiting the number of people who could implement their ideas. At the same time, the team is constantly refining the usability of the product based on countless hours of customer research, leaning on the strengths of their product designer, Mikael, and cognitive scientist, Anja.
When the original Project Odyssey team set out to build Excel in 1985, they wanted to make it easy for users to perform calculations and create graphs. They could never have predicted the myriad ways over 750 million people would bend and expand the product. They just knew that the more flexible and usable they made it, the more possibilities they would create.
Build for Your Passionate Core. Part of the reason Excel will never die is because there are so many passionate Excel practitioners. Inspired by Excel products should be flexible enough for non-target users to use (I love using Figma although I\u2019m terrible at it) but endlessly challenging and rewarding for the target group.
Some of the greatest excitement in the deep learning world relates to generative models that can create entirely new proteins, never seen before in nature. These modeling tools belong to the same category of algorithms used to produce eerie and compelling AI-generated artworks in programs like Stable Diffusion or DALL-E 2 and text in programs like ChatGPT. In those cases, the software is trained on vast amounts of annotated image data and then uses those insights to produce new pictures in response to user queries. The same feat can be achieved with protein sequences and structures, where the algorithm draws on a rich repository of real-world biological information to dream up new proteins based on the patterns and principles observed in nature. To do this, however, researchers also need to give the computer guidance on the biochemical and physical constraints that inform protein design, or else the resulting output will offer little more than artistic value.
