Chapter 358

Back in Kyoto, Xu Qingzhou and Song Yao started getting busy with their own affairs again—one went to the library for self-study, while the other went to report to Li Daiyue.

Although they had a 10-day vacation, Song Yao still had tasks, working on a stock market turning point prediction method based on the hidden semi-Markov model of emotional vectors.

She had already completed part of the content during the vacation and planned to show it to Li Daiyue today.

Days passed by, and Xu Qingzhou was methodically recommending calculations, but it still wasn't as smooth as he had imagined. Until October, the model still hadn't been completed.

After all, the AB effect and quantum entanglement are concepts describing two different physical phenomena.

Linking them is extremely difficult.

Xu Qingzhou solved the entanglement entropy problem, but the phase modulation function had issues. After solving the phase modulation function, non-locality led to a more complex causal structure...

Mountain after mountain, danger after danger.

Consequently, he would work on the AB effect for a few days, and if he had no ideas, he would go to ponder the problem of local smoothness conjecture.

On September 16th, Xu Qingzhou received a call from Guo Ziyang.

After more than 4 months of struggle, by September 16th, the project led by Guo Ziyang was nearing its end, so he called to ask Xu Qingzhou about the submission of that paper on IPC.

In the empty classroom, Xu Qingzhou moved his gaze away from the draft paper and looked out the window to relax his eyes, saying: "Just submit it with yours."

"Ah? Isn't it a bit rash for your paper to be submitted to a core journal with ours? I heard from the teacher that submitting it to a Tier 1 SCI journal shouldn't be a problem."

Xu Qingzhou shook his head: "No time to translate, just like this."

"This is a Tier 1 SCI paper, are you sure?" Guo Ziyang asked.

He had heard Xu Qingzhou say he had published a few more SCI papers before, and he didn't have such a big feeling at the time. But when he started working on his own project and preparing his paper, he realized this stuff was truly damn hard.

His group had worked their lives out for over four months, and the stuff they produced barely had a chance to get into a core journal.

"It seems I'm not short of SCI papers." Xu Qingzhou said with a laugh.

"..."

Guo Ziyang fell silent. Damn, why hadn't he noticed this guy was so pretentious before?

Xu Qingzhou was indeed too lazy to deal with this stuff. The two problems right in front of him were already enough to give him a headache.

How could he spare the energy to translate the IPC paper?

For Xu Qingzhou, publishing SCI was simply too easy; as long as he wanted to pad his numbers, there were plenty of ways.

Take this IPC paper, for example.

One could be published by doing research according to the old method, and now another one could be published with this improved model. By comparing the two and systematically expounding the differences, a third one would come out.

Or, one could take the part about replacing the direct method with preconditioned conjugate gradient (PCG) to solve the sub-linear system in the barrier-based augmented Lagrangian iteration model and make it into another one.

However, these didn't have much meaning.

He didn't need to pad his paper count to cope with reviews.

Guo Ziyang: "Alright then, I'll put it together with ours."

"Okay, won't talk anymore, I'm busy."

Both were very busy, so they hung up the phone after talking about business.

In the empty classroom.

"Hoo~"

Xu Qingzhou let out a breath, looking at the formula on the draft paper, and couldn't help but rub his temples.

Using this finite overlap property, without counting the rapidly decaying terms, one can now return to the proof of (5.13). In the sense of differing by a negligible term, one only needs to prove the following inequality:

And then, he couldn't move forward.

Xu Qingzhou stared at the inequality for a long time, shook his head, stopped struggling, and sent a message to Song Yao: "Go running tonight?"

After exercising with Song Yao for a long time, he found that running seemed to be addictive; after being busy for a few days, he wanted to go sweat it out.

After a while.

Song Yao: "Teacher Xu, you've finally grown up, I'm very gratified." Xu Qingzhou: "Kitchen knife. jpg."

Song Yao: "I can only finish here at 6 o'clock, let's go to the playground at 7."

A few more people came into the classroom, looking like they were there for self-study.

Freshmen entering school still held longing for the school and maintained the drive to learn, or rather, had an inexplicable yearning for the library, coupled with the newly surging army of graduate school entrance exam takers, leading to a shortage of seats in the library.

Xu Qingzhou had been finding empty classrooms during this period.

"Damn, changed my brain."

Thinking this, he took out the calculation manuscript for the AB effect again.

Guo Ziyang had finished his project and went to the office of his advisor, Zhang Rongxuan.

Zhang Rongxuan was checking the project completion materials and suddenly paused, "Submitting all to *Journal of Software*?"

"Yes." Guo Ziyang nodded.

(In the classroom)

"This paper, *On the Modeling Improvement of IPC in the Field of Graphics and Contact Mechanics*, is also submitted to *Journal of Software*... You didn't tell Xu Qingzhou that it could completely be submitted to a Tier 1 journal?"

Guo Ziyang scratched his head, "I told him, but he's been quite busy lately and doesn't have time to translate it. Moreover, he also said he's not short of this Tier 1 paper."

"..."

Not short of Tier 1 papers...

This kid is really arrogant. Let alone students, even some professors nowadays can't get into them.

Looking at Zhang Rongxuan's complex expression, Guo Ziyang sighed inwardly. This feeling of "second-hand pretentiousness" didn't seem bad either.

Zhang Rongxuan waved his hand, respecting Xu Qingzhou's choice, "I've seen the stuff, there's no problem, go ahead and submit it."

Guo Ziyang didn't waste time; after returning, he submitted all three papers.

The next day, *Journal of Software* editorial department.

Yang Hongbin was checking submissions while chatting with his colleague in the next office, Jia Wenyu, "Undergraduate, elastomer contact simulation, that's difficult. Undergraduates basically can't produce anything useful..."

"Wait, corresponding author, Zhang Rongxuan?"

Yang Hongbin originally wanted to put it aside to look at later, but suddenly noticed the corresponding author's name, "This is an undergraduate student led by Old Zhang, eh."

Jia Wenyu looked and said with a smile: "This guy is quite idle, actually running off to guide undergraduates."

Yang Hongbin also smiled, but after seeing Zhang Rongxuan's name, he became much more serious and scanned through the three papers.

His gaze fell on the last paper, "I seem to have seen something strange, IPC model improvement, first author, Xu Qingzhou, the name sounds a bit familiar."

"Jingda's Xu Qingzhou?" Jia Wenyu leaned over.

"Seems it really is."

Yang Hongbin clicked on the paper, wanting to see what high insights this mathematics major had.

"Seems... there's something to it." Jia Wenyu was also seriously reading the paper.

Soon, both of their expressions gradually became serious, staring tightly at the screen.

"Based on the augmented Lagrangian iteration model, skipping the calculation of the sparse matrix pattern, this model is written awesomely."

"As expected of someone doing mathematics, the matrix operations are also done quite perfectly."

"The calculation speed is 70 times more efficient than before!"

"This thing should be counted as an important breakthrough in the field of graphics and contact mechanics in recent years, right?"

"Definitely counts."
