aThe maximum output powers of 2W at 1342 nm and 1.8W at 1063 nm were obtained at the incident pump power of 12.6W, and both have the roughly same average slope efficiency of ∼ 18.7%. 2W的最大输出电力在1342毫微米和1.8W在1063毫微米得到了在12.6W的事件泵浦力量,并且两个大致有同样平均倾斜...
This year, the talk of the town was AI and how it can do everything for you.I like it when someone or something does everything for me. To this end, I decided to ask ChatGPT to write my New Year's post:"Hey ChatGPT. Can you implement a large language model in SQL?" "No, ...

The explanation for Manhattan block conversion appears to be wrong. They mention that their calculation for how large one block is was made with 4 numbers ignoring George Washington as an outlier. However there are 6 total examples of Manhattan block to use and George Washington's is not an ...
Experiments powersciencelike gasoline powers a car. If you have a theory about how the world works, it's a basic rule of science that you need to test it with an experiment. If your experiment confirms the theory, great; if not, refine your theory and do some more experiments. Although...
In this comic the viewer can select a thrower and an object to be thrown, see this table, and get an animation of how the selected throw would work out, along with an estimated distance of the throw (both in the SI unit meter (m) and in other very arbitrary units; see this table ...
Bias and variance are obtained by calculating the mean and variance of the estimator over 150 trials, respectively. Full size image These experiments and discussion in the previous section provide illustrations of the three main heuristics about how dataset, kernel, target function, and noise ...
“The need for a quick, satisfactory copying machine that could be used right in the office seemed very apparent to me—there seemed such a crying need for it—such a desirable thing if it could be obtained. So I set out to think of how one could be made.” ...
How do all these things get into your life? Up to a third of all the plastic we use finds its way into the packaging we use to protect products (sometimes even plastic products) on the journey from factory to home.Photo: Plastics in action: NASA's plastic Pathfinder aircraft in flight...
