Qiu Sheng was stunned for a moment, and a name blurted out:
"Jushi Yi An, Li Qingzhao?"
Xu Yun nodded slightly, turned sideways, and exhaled with a complicated expression.
Even though he is now a human being in two lifetimes, his mentality is relatively peaceful and he takes events such as life, separation and death a little less seriously than ordinary people.
But the copy of the Northern Song Dynasty is still an indelible memory in his heart.
The fate of Xiao Li in the copy was changed by him, from a female poet to a biologist with double majors in arts and sciences, and discovered a variety of microorganisms.
As for Xu Yun, he received a new species as a reward during the dungeon settlement.
Is there really no connection between the two?
No one may know the real answer, but Xu Yun personally thinks it is no.
Naming this new species after Xiao Li is a very appropriate choice both in terms of meaning and sentiment.
However, Qiu Sheng couldn't understand Xu Yun's thoughts. He simply felt that the name seemed okay and said:
"Lao Xu, this name is not bad. Besides, it is a new species you discovered. You can call it whatever you like. I have no objection."
Xu Yun nodded towards him, pondered for a moment, and then asked:
"By the way, Lao Qiu, do you have any ideas about the donkey's hair growth plan?"
Qiu Sheng frowned and thought for a while, then slowly shook his head and said:
"I've heard in novels that the blood of a bat girl can make a dog girl grow hair, but in reality we can't find a mother-in-law who has been poor for ten thousand years, so this is obviously impossible."
"The remaining methods are nothing more than black sesame or minoxidil - my suggestion is to use both. Anyway, it seems that this donkey is very resistant so far, and most likely nothing will happen."
Minoxidil may not be very popular, but it is actually one of the internationally recognized mainstream drugs for treating hair loss, and its usage rate is very high.
However, the effect of this thing is somewhat limited. It can only be said that it is better than the placebo. It is probably the best among the shortest.
Everyone should be familiar with black sesame seeds. Together with Polygonum multiflorum, they are known as the two traditional food supplements and hair growth ingredients.
It would certainly not be wrong to call it nonsense or an IQ tax, but its effect is relatively limited.
However, considering that there is currently no particularly effective method, these two things have become the only options.
Of course.
Hair growth is only a temporary solution, the more important thing is to breed - it is not good to catch the donkey brother all the time.
However, it is quite difficult to find purebred local female donkeys with LP phenotype these days, because there are too many hybrid donkeys in our country.
All classmates who were donkeys in their previous lives should know this.
The life span of a donkey is generally 20 years, which is almost more than 100 years in human lifespan.
In other words, almost all the native donkeys, male and female, were dead before 2000 years ago.
The time when Pakistani donkeys were introduced to the country on a large scale happened to be around 2001 and 2002, exactly 20 years ago.
The smallest unit where these donkeys were released was the town-level livestock station. The policy was to have grassroots cadres go to the countryside to promote the donkeys, and the breeding coverage was extremely high.
Therefore, it is currently very difficult to find purebred native female donkeys, and crossbreeding cannot activate the LP phenotype, let alone obtain the pentose phosphate pathway products that are present in hair.
Of course.
The genes of native donkeys must be preserved in the domestic species gene bank. After all, rabbits are all old hamsters.
But the key is whether brother donkey’s gender is ♂ or not ♀. Even if he has the gene, he can’t have offspring...
Incidentally.
The largest species gene bank in China is located in Qian Province, and the headquarters of the world species gene bank are built in two places:
The crop seed bank is in Longyearbyen, the city closest to the Arctic.
The seed vault is buried 130 meters underground. The entrance is a bare wedge-shaped building standing on a gravel slope.
In China, it only costs about 10,000 Chinese dollars to go to Longyearbyen for seven days. If financial conditions permit and you want to see polar bears, Longyearbyen is a good choice.
As for the animal gene bank, it is in Ushuaia, the city closest to Antarctica, and the entrance is top-secret.
Both genebanks were built by the Global Crop Diversity Trust to have a backup in case the planet encounters some extreme conditions.
Therefore, the two gene banks can receive a lot of strange things every year. The seed bank is naturally a bank of various plants and animals... ahem.
The topic returns to its original place.
all in all.
Until he finds a suitable breeding female donkey, Brother Donkey will probably have to be a sheep that gets shaved for a while.
Then Xu Yun thought of something else and asked Qiu Sheng:
"By the way, Lao Qiu, have you read the document on the digital media?"
Qiu Sheng's expression was quite normal at first, but when he heard this, his face suddenly turned bitter and he pointed at himself with his index finger:
"Brother, you think I'm Superman, right?"
"This one is still doing research on a new strain of... Yi'an bacteria, and the other one is looking at a feasibility review of DNA storage technology. Do you really think I'm the donkey in the cafeteria?"
"...."
Facing Qiu Sheng's complaints, Xu Yun chuckled and scratched his head tactically, trying to make himself look less embarrassed.
Just like Qiu Sheng said.
In the past few days, he has been busy with the issue of the release of Zhidao. Most of the time he was at the company or Tian Liangwei.
There was little time to stay in the laboratory, so Qiu Sheng did take on a large part of the research tasks.
However, he just casually asked about digital media. This thing is the DNA storage technology that he got as a reward.
Different from imidacloprid and erythromycin.
At present, Xu Yun has not thought of its specific commercial use, and technological breakthroughs cannot be made in a day or two.
Therefore, he is not prepared to put too much energy into this area. If there is no sudden breakthrough, the current key point will still be Yi'an Bacteria.
correct.
award?
As these two words flashed through his mind, Xu Yun suddenly thought of something else:
Among the eight rewards originally given by Halo, except for the mysterious disappearance of the National Fortune, six have been completely unveiled - at least it can be regarded as knowing how to get started.
But there was only one reward, and Xu Yun never had time to study it.
That is......
That piece of soft paper with a lot of mathematical formulas burned on it.
Then he went over his schedule in his mind.
I found that I still have a lot of free time today, so I can try to study the formula.
Think of this.
He couldn't help but look at Qiu Sheng and said:
"Lao Qiu, I still have some things to do right now. Look at the laboratory..."
Hearing this, Qiu Sheng glanced at him and sighed as if he was resigned to his fate:
"Can you please give me a hand in the laboratory? Mr. Sun, get out of here!"
Xu Yun was not polite to him either. He put his index and middle fingers together, placed them next to his temples and made a stroke forward:
"Then daddy just leave!"
Qiu Sheng didn't say anything, but gave him a middle finger.
After leaving the laboratory.
Xu Yun walked quietly on the way to the library alone.
Qiu Sheng's previous words in the laboratory made him suddenly realize another problem:
The company's R&D manpower is somewhat insufficient.
Currently, there are only two real core personnel on the company's R&D side, namely him and Qiu Sheng.
Needless to say, Qiu Sheng's ability is more than enough to lead the Institute of Biochemistry of USTC in the future, and he can at least be responsible for one project at the moment.
As for Xu Yun...
The reason why he focused on business before was mainly because the company was a start-up. "One Mantis" is also a key product that determines the cornerstone of the company, and he must follow up at any time.
Now that the company is on the right track, he will definitely focus on research and development - otherwise he would not have hired Gu Qunqing, a returnee from overseas, as COO.
But other than that.
The company doesn't have many available people.
The remaining R&D personnel are either current students like Ren Yongcun and Zhou Peiyao who came to work on projects, or they are graduate students recommended by Tian Liangwei.
These people are capable, and their future is promising.
But for now, they are still far from being responsible for a single project.
Now that Xu Yung has just gone through two copies, he now has two commercial products, imidacloprid and Yi'anbacteria, to be broken through, not to mention that there is also a DNA storage technology that needs to be researched later.
What about the third and fourth copies?
To know.
These projects are not a one-stop solution.
It is a ‘technology tree’ with quite a few derivative fields.
Even the simplest one, imidacloprid, has quite broad derivative prospects.
For example, although the sodium ion channels of cockroaches are different from those of mice, they are very close to those of mosquitoes.
If a product that is effective against mosquitoes can be developed, the market may not be much smaller than killing cockroaches.
Moreover, as a company that intends to grow into a towering tree, there must be a big boss in the scientific research department.
True.
Huadun Biotechnology is backed by HKUST and can fully integrate industry, academia and research.
However, the integration of industry, academia and research does not mean that Xu Yun can directly poach people from HKUST.
If you occasionally ask HKUST to help you with some research and development tasks, it’s definitely fine, but do you want a professor or even an academician to work directly for you?
This is obviously impossible, even for Tian Liangwei, who has the closest relationship with Xu Yun.
Therefore, it is based on emotion and reason.
Xu Yun must find one or even several experts who can become pillars as soon as possible.
But this is easy to say, but equally difficult to do.
The support Xu Yun needs is not an ordinary doctor or professor, but a super boss with academician-level abilities.
But Chinese academicians say more and less, let alone biology majors.
Under such circumstances, how can it be so easy to find a great person that you like each other?
Think of this.
Xu Yun couldn't help but sigh quietly.
So let’s work hard on Qiu Sheng first...
Fifteen minutes later.
Xu Yun arrived at the library.
After swiping his card and passing the access control, he first got a glass of water and found a deserted corner to sit down.
Then he took out the piece of paper with the equation written on it from his body.
This is a complex system of equations composed of regularized combination coefficients and analytical continuations, which is very troublesome to solve.
The only judgment Xu Yun made at that time was that the solution to the last equation must be a ratio.
But after enough time today, he discovered another situation.
I saw that he drew two lines next to the third and fifth lines of the equation, and put a question mark.
A thoughtful expression:
"seem......."
Gu Xue
"The compound equation system on this piece of paper can be divided into three parts for calculation?"
As we all know.
Regularization theory was first proposed to solve ill-posed problems.
It has long been believed that mathematical problems derived from practical problems are always well-posed.
As early as the beginning of the 20th century.
Hadamard observed a phenomenon:
In some very general cases, the problem of solving linear equations is ill-posed.
Even if there is a unique solution to the equation, if an arbitrarily small perturbation occurs on the right side of the equation, the solution of the equation will change greatly.
in this case.
If you minimize a norm function of the difference between both sides of the equation, you cannot obtain an approximate solution to the equation.
By the 1960s.
Tikhonov, Ivanov and Phillips also discovered the additive regularization term that minimizes the error norm function.
That is, by regularizing the norm function, instead of just minimizing the error norm function, you can get a solution sequence for an ill-posed problem that tends to the correct solution.
In other words.
The first part of the system of equations is actually a collection of sequences describing the gradient region.
Maybe even...
image?
Think of this.
Xu Yun suddenly became interested.
It can be judged from 4D/B2 that this should be a problem involving a rotating surface.
The second line of ∑(jik=S)∏(jik=q)(Xi)(ωj) can determine that the surface and the meridian form a certain angle.
Since it is a fixed angle, we can assume a fixed model λ = ( A , B , π), and an observation sequence O = ( o1 , o2 ,..., oT ).
Then there is α1(i)=πibi(o1), i=1,2,...,N
αt+1(i)=[j=1∑Nαt(i)aji]bi(ot+1), i=1,2,...,N
Fifteen minutes later.
Looking at the results in front of him, Xu Yun thoughtfully said:
"Maximizing model parameters..."
Then he thought for a moment and continued to write a formula on the paper:
This is a very simple projection curve, and the torsion of any point on the conic logarithmic spiral is also inversely proportional to the distance from the point to the axis.
Therefore it can be reduced to another expression.
As he explained, Xu Yun's expression became more solemn.
Two hours later.
Xu Yun looked at the drawings in front of him and frowned tightly:
"Good guy, the solution term of the first set of equations is actually an equation of the observation state?"
The observational equation of state is actually a very strange thing. Its interpretation in mathematics is relatively complicated, but its interpretation in physics is very simple:
It represents a time-series non-probabilistic model, which refers to the non-random process of transition from one state to another in the state space.
See here.
Do some students feel familiar?
That's right.
This is a model that is completely opposite to the Markov chain in definition, describing a qualitative possibility within a small interval.
And this kind of model usually only appears in...
Super super small microscopic field.
Think of this.
Xu Yun suddenly had a flash of inspiration.
"Microscopic realm, decay integral?"
I saw him quickly picking up the pen and quickly writing a line of words on another piece of paper:
y(xn+1)?y(xn)/h≈f(xn,y(xn))
y(xn+1)=y(xn)+hf(xn,y(xn))
After writing this.
Xu Yun took out his notebook and opened a customized version of the physics software.
This is a quantitative calculation program that can only be applied for by HKUST graduate students. It runs on the basis of quantitative calculations made by Gaussian and can calculate some models with limited accuracy. It is called Aurora.
The trajectory of all particles discovered so far has been recorded in Aurora, and it is connected to a secondary server on the same campus of HKUST.
Xu Yun then recognized the formula he had written through Mathpix, transferred it, and pressed the Enter key.
Twelve seconds later.
A number appeared in front of Xu Yun:
0.
This 0 is not the unreliable 0, but means that no result matching this eigenvalue has been found in the system.
"Strange......"
Looking at the 0 in front of him, Xu Yun turned his pen and muttered to himself doubtfully:
"There are no results that match the eigenvalue... There are no input errors in the equations. Could it be that there is something wrong with my idea?"
Follow his train of thought.
After simplifying the first part of the equations, an observation state equation appeared, so he tentatively performed an integral simplification.
In the end, he used the difference quotient to approximate the period derived by the derivative, which finally seemed to be consistent with the attenuation magnitude of particles in the light field.
In other words.......
It seems to match the trajectory of some kind of particle.
But now the result obtained by Aurora is 0?
Or...
Is this a new particle that has never been discovered before?
As we all know.
According to the current standard model of particle physics, there are 61 types of elementary particles that we temporarily consider, which are divided into four parts:
Quark.
Lepton.
gauge boson.
and Higgs particles.
Of course.
There is also an unconfirmed particle, the "graviton".
It is a hypothetical particle used to transmit gravitational interactions, so I won’t go into details here.
Among them, matter is composed of fermions, including quarks and leptons.
Quarks can form baryons and mesons through strong interactions. Protons and neutrons in baryons can form atomic nuclei, which are also fermions.
At the same time, atomic nuclei and electrons can form atoms, and then form the world we see.
What transmits the interaction are gauge bosons, which are used to transmit the interaction force between fermions.
For example, photons are the gauge boson we are most familiar with.
It is the Higgs particle that gives mass to elementary particles - this is more complicated to explain in detail. For example, although the mass of elementary particles comes from Higgs particles, the main source of the visible mass of the universe is the strong interaction, which is a concept at the doctoral level. In short, conceptually
Just understand it.
And on the other hand.
These basic particles can form a very large number of composite particles, and the number of composite particles depends on which scale you are talking about.
If it is at the atomic level, then there are n types of each element and their isotopes.
If you are specifically referring to subatomic particles, then generally consider mesons and baryons, as well as some special particles.
For example, photons have 225 structures, electromagnetic particles have 2,700 structures, etc.
It's like we classify birds as one species, but birds can also be subdivided into sparrows, turtle doves, eagles, and many other categories.
The same goes for human beings. They can be divided into non-chief European emperors, and they can also be divided into male and female Hideyoshi.
Think of this.
Xu Yun pondered for a moment and clicked a few more times on the browser's bookmark page.
Opened a website of Mingjiao pdgLive.
This is a website that specializes in collecting subatomic particle information. You can find a large amount of subatomic particle information on it.
Including those that have been confirmed by experiments and have measured properties, those that have been experimentally proven to exist, those that exist theoretically, those predicted by new theories, etc.
Xu Yun then switched back to Aurora software, changed y(xn+1) to y(xn+2), and ran it here.
soon.
The software simulated a binding energy number:
1.26342MeV.
"1.26342MeV..."
Xu Yun wrote down this number and compared it with the constant mass spectrum on the website to identify the mass peak.
Although current tunneling microscopes can 'see' atoms, this is actually a metaphor.
In the field of scientific research, the true determination of new particles still relies on colliders and other equipment.
The specific method is very simple, just one word:
boom.
Just use chestnuts to collide with particles, and then measure data such as scattering cross sections to make graph analysis.
For example, if a collision process generates muons, the muons will decay into other particles, so that the mass peak of the muon can be found on the constant mass spectrum.
The cost of such a detection is a real astronomical value, and the simulated auroral values are obviously impossible to compare with in terms of accuracy.
Therefore, 1.26342MeV is not an accurate value and needs to be screened again.
"1.379867MeV....too high..."
"1.129973MeV...this is too low..."
"1.14514MeV, still not enough..."
Xu Yun just compared them row by row.
My eyes were a little sore, but I didn't dare to slack off at all.
A few minutes later.
His eyes suddenly condensed and locked tightly on one of the columns:
"Huh? 1.26812MeV?"
This is the binding energy level that he has discovered so far that is closest to the auroral display number, and the error is only two decimal places.
See this.
He immediately moved the mouse and clicked on the information volume.
After a while.
Xu Yun's pupils shrank heavily and he almost screamed in surprise in the library.
I only see this moment.
On the screen in front of him, a line of information was written:
Particle name:
Λ hyperon(4685)
Date of discovery:
November 18, 2022.
Found unit:
Huaxia University of Science and Technology, Zhao Zhengguo.
