Inversion

For many startups, getting a spot in an accelerator program like Y Combinator or TechStars is like winning the golden ticket to Willy Wonka’s chocolate factory. Accelerators offer a wealth of opportunities that can make the difference between a great idea that doesn’t achieve its potential and one that leads to an IPO. We’re accustomed to seeing accelerators work for companies disrupting travel, payment processing or cloud storage, but what if that model could work outside the ambit of the VC…

Stick insects, Timema knulli, on a Redwood tree branch. Utah State University evolutionary geneticist Zach Gompert and colleagues studied a chromosomal inversion in the species and report findings in the June 12, 2023, online edition of PNAS. Credit: Moritz MuschickThe complexity of evolutionary processes affecting an inversion in stick insects provides resilience against loss of genetic variation, and may foster long-term survival.Genetic variation is the ultimate fuel for evolution, says Utah State University…

The picture depicts the cyclic inversion process of GONGGA inversion system. In each inversion cycle, CO2 inversion and flux inversion are performed successively. Credit: ©Science China Press Scientists from the Institute of Tibetan Plateau Research, Chinese Academy of Sciences developed an atmospheric inversion system GONGGA (Global ObservatioN-based system for monitoring Greenhouse GAes) to infer CO2 sources and sinks from…

Improve Article Save Article Like Article Improve Article Save Article Given a Binary Array arr, the task is to count the number of inversions in it. The number of inversions in an array is the number of pairs of indices i, j such that i < j and a > a.Examples:Input: arr = {1, 0, 1, 0, 0, 1, 0}Output: 8Explanation: Pairs of the index (i, j) are (0, 1), (0, 3), (0, 4), (0, 6), (2, 3), (2, 4), (2, 6), (5, 6).Input: arr = {0, 1}Output: 0Approach: Follow the below steps to solve the problem:Initialize the variable…

Yields on longer-term U.S. Treasurys have fallen further below those on short-term bonds than at any time in decades, a sign that investors think the Federal Reserve is close to winning its inflation battle regardless of the cost to economic activity.A scenario in which short-term yields exceed long-term yields is known on Wall Street as an inverted yield curve and is often seen as a red flag that a recession is looming. Yields on Treasurys largely reflect investors’ expectations for what short-term interest rates set by…
