207: Chapter 207 Special Underlying Architecture

Professor Robert switched to a slide that displayed a highlighted section of core algorithm code.

"However, during the replication process, David and I discovered a more interesting and thought-provoking issue."

The scholars in the audience raised their heads one after another, looking at Robert with curiosity in their eyes.

"This scholar named Zhao Yang creatively used a data arrangement structure that we have never seen before."

Robert scanned the crowd, his eyes shining with excitement.

"This data arrangement structure is extremely streamlined, with almost no redundancy. It is a direct memory call logic similar to a machine's underlying instruction set."

The scholars in the meeting room stared at the slide before them, carefully scrutinizing everything Robert had just said.

"This style of writing is too dangerous."

A researcher spoke up with hesitation in his eyes.

"With this style of writing, when programming complex distributed engineering involving tens of thousands of lines of code and concurrent calculations across hundreds of nodes, using direct memory calls makes it very easy for memory overflows or pointer errors to occur.

If the memory address calculation of even a single node has a deviation of just one byte, the entire system will completely crash."

"Exactly, that is the crux of the problem."

Professor Robert tapped the table, his tone becoming more emphatic.

"A normal human programmer cannot maintain absolute focus within such a massive volume of code, but he did it! He achieved this across tens of thousands of lines of code and hundreds of nodes!"

"Professor, what do you mean?" A postdoctoral fellow raised a hand to ask.

Looking at the postdoc who asked the question, Robert gave his judgment.

"I mean, this isn't just an innovation in an algorithmic model. From his coding style, I see the prototype of a brand-new computer language architecture. An underlying architecture born entirely for the pursuit of ultimate computing power and extreme execution efficiency."

A brief silence fell over the meeting room.

Everyone was stunned by Professor Robert's deduction. Solving problems in existing deep learning frameworks was merely a breakthrough at the application level; however, building a brand-new underlying computational language architecture was a feat that could pioneer a new era.

"If he is truly working on building this kind of underlying computational language... gentlemen, then we are facing a century-level genius in the field of computer science who is sufficient to stand alongside or even surpass Turing and Von Neumann," Robert gave an extremely high evaluation.

He didn't give the others any more time for discussion and turned directly to his administrative assistant to issue instructions.

"Immediately look up the specific contact information for Beijing Forestry University where this Yang Zhao is located. Prepare a formal invitation letter."

Professor Robert quickly arranged the follow-up matters: "In the name of the MIT Computer Science and Artificial Intelligence Laboratory, I want to invite this Dr. Yang Zhao to the United States for a six-month academic visit. Offer him the highest level of visiting scholar benefits, cover all expenses in full, and grant him access to the laboratory's core supercomputer. No matter the conditions, we must strive to have him come here for an exchange."

The assistant nodded immediately and took out a notebook to start recording.

...

Zhao Yang, sitting in his apartment in the Young Teachers Apartments at Beijing Forestry University, was completely unaware of the deep analysis of his coding style happening in the MIT lab across the ocean, or the upcoming transoceanic invitation for a visiting scholarship.

His attention at this moment was entirely focused on the chemical experiment data on the computer screen in front of him.

He was currently processing the batch of brand-new battery test data that Professor Wu Kai from CATL had sent someone over urgently this afternoon.

This batch of batteries had been doped with trace amounts of titanium during the co-precipitation synthesis stage. Their electrochemical cycle life and high-rate discharge performance were better than anyone expected, even breaking through the theoretical upper limit given by Zhao Yang's previous mathematical model.

The laboratory researchers couldn't determine which specific microscopic mechanism change this exceptionally excellent performance originated from. They could only package the massive amounts of test data and physical parameters across different temperature gradients and send them all to Zhao Yang, hoping he could find the core intrinsic variables through mathematical dimensionality reduction analysis.

After more than three hours of high-intensity data modeling and mathematical calculation by Zhao Yang...

He finally identified all the most critical factors affecting the battery from this mountain of variables and turned them into a scatter plot.

Zhao Yang stared at the scatter plot on the computer screen.

From this chart, the relationship between the titanium doping amount and the final cycle life was not a simple linear one; instead, at a certain specific sintering temperature, an extremely abrupt peak in cycle life would appear.

"The radius of the titanium ion is close to that of the cobalt ion. The conventional understanding is that it enters the crystal lattice of the ternary material, acting as a pillar to stabilize the lattice."

Zhao Yang murmured as he looked at the scatter plot, combining it with all the data he currently possessed.

"But if this were just simple bulk doping, it wouldn't be enough to improve the cycle life under high voltage to this extent. The polarization internal resistance data still shows no significant increase after a hundred cycles, which indicates that the contact interface between the cathode material and the electrolyte has undergone a fundamental change."

He imported several sets of data at different temperatures into the model for fitting.

Soon, the conclusion presented itself clearly.

"Under the specific sintering temperature gradient of 830 to 840 degrees Celsius, driven by thermodynamics, a small amount of titanium reacts with the residual lithium on the surface, forming an extremely dense nanometer-scale lithium titanate coating layer."

"It is precisely because of this lithium titanate coating layer that the interface side reactions are largely suppressed, preventing the dissolution of transition metal ions."

"This is the core reason why this batch of materials' cycle life could break through five hundred cycles."

Having found the reason, Zhao Yang did not delay. He quickly organized his conclusions and data into a rigorous data analysis report.

He converted the document into PDF format and sent it directly to Professor Wu Kai through the encrypted email channel established previously.

After clicking the send button, the email showed it was successfully sent.

Zhao Yang leaned back against his chair, closed his eyes, and rubbed the slightly aching corners of his eyes with his hand.

He glanced at the time in the bottom right corner of the screen; it was already twelve o'clock at night.

After more than three hours of high-intensity modeling and calculation, even though Zhao Yang's current physique stat was as high as 18—giving him physical fitness far exceeding that of an ordinary person—he still felt tired at this moment.

He walked to the bathroom for a quick wash, then lay down on the bed and quickly entered a state of Deep Sleep.

Meanwhile, at the CATL R&D Center in the Yizhuang Economic and Technological Development Zone in Yanjing...

Professor Wu Kai had not gone to rest.

He sat at the computer in his office, drinking strong tea to stay refreshed while waiting for Zhao Yang's data analysis results.
