the most basic understanding of stars and realized that stars were not constant in the sky. At the beginning of the 20th century, Einstein published the famous mass-energy relationship, people gradually realized the huge energy produced by the nuclear reaction and knew the source of the star's...
We study the evolution of the star formation rate (SFR) of mid-infrared (IR) selected galaxies in the extended Chandra Deep Field South (E-CDFS). We use a combination of U-K GaBoDS and MUSYC data, deep IRAC observations from SIMPLE, and deep MIPS data from FIDEL. This unique multi-wa...
usually away from the goal, as we see Saka doing in the screenshot above. This task — proper positioning — is the heart of defending.盘带 — 然后,防守者应该耐心地引导对手到威胁较小的位置,通常是远离球门,就像我们在截图中看到萨卡做的那样。这个...

It is widely held that the bilaterian tubular gut with mouth and anus evolved from a simple gut with one major gastric opening. However, there is no consensus on how this happened. Did the single gastric opening evolve into a mouth, with the anus forming
