(Saturday, September 21, 2013, morning; apartment 4th floor, Akiyama Soraya)

"I'm coming, Akiyama!"

Sora Akiyama opened the door, smiled and hugged the lover in front of him into his arms, and then kissed each other lightly on the lips, and then let go of his arms. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 infoA few minutes later, the two of them each had a tablet in hand, leaned back on the couch that followed the curve of their spine, and were ready to start today's content.

Nanamiya Tomoin came to him to listen to the lectures. On the one hand, he wants to check the girl's learning progress and knowledge understanding, and on the other hand, his incisive explanations can make the other party learn twice the result with half the effort.

"There is nothing wrong with the fundamental theorem of calculus, and the method of finding the original function of the commutation is also OK, so you can just brush the problem to increase your proficiency. ”

In fact, calculus in "Advanced Mathematics" is the simplest basic course of science and engineering, and the functional analysis and real function are the real difficulties. As for the "mathematical system" of the Spirit Race that he inherited from his previous life, it was an existence that had to be described in another language.

When Nanamiya Tomoon was working on the question, Akiyama Sora was not idle, but picked up the tablet to read the literature pushed. This paper, from the recent issue of Nature Neuroscience, describes a new multifunctional flexible polymer fiber probe that can simultaneously transmit a combination of light, electricity, and chemical signals to the brain, while itself thinner than a human hair. Electrical and chemical signals are well understood, while optical signals are mainly injected into the nervous system by means of genetics, and the opsin genes that are integrated into the genome of host nerve cells can make them light-sensitive.

This probe is composed of graphite/conductive polyethylene composite electrode, polycarbonate waveguide core layer, cyclic olefin copolymer coating and hollow fluid channel, etc., which is quite compatible with neural tissue. Compared to the traditional rigid probes previously used by Sora Akiyama and other laboratories at the institute, this probe, like the previous flexible mesh brain-computer interface, can be more easily implanted into the brain and remain functional for a long time, but it is not easy to stimulate it to produce scar tissue, so that physiological activity within the brain can be better monitored.

"Whew, done. The girl next to him shook his arm, "What are you looking at?"

"A new type of brain-computer interface. ”

He explained the content of the article to the other party succinctly. Qinomiya Zhiyin's English level is not as good as his who has studied language logic, and it will take an hour or two to read through the whole text, not to mention that she does not need this for the time being.

"Researchers don't bother to read any literature. This paper is directly related to my field of study, so I read it word for word. But for other fields, I prefer to read popular science articles with dry goods, or short explanatory essays on the original paper. ”

It's Saturday, and Akiyama and Sora naturally don't plan to eat books all day. While taking a break, Nanamiya Tomoin told him about the fact that Tokuka Tori had come to her last night.

"In other words, what should have happened has happened!"

"Well,[Theocracy] corrected the world for 12 years.,And Tomakashi's photo album dates back to 10 years.,In the final analysis, it's his own problem.。 ”

"Hee-hee...... I don't know how Liuhua-chan and the brave man are doing now, and whether the exchange last night went well?"

"I don't know that God's perspective is not so abused. Sora Akiyama shrugged, "But the two of them are different from those in the parallel world." ”

"Well, that's true. Why don't we go and have a look?"

(Saturday, September 21, 2013, morning; 2nd floor, Yuta Tomigashi)

Sora Akiyama and Tomoin Nanamiya were a little embarrassed at first, but after thinking about it, they learned from the three of Dansheng Gu Senxia in the parallel world to go to the opposite apartment and squat, but they looked at it stupidly for more than half an hour, and they didn't see anything wrong - Yuta Tomigashi and Yuroka Bird Yuyaka came out to dry their clothes and never appeared again.

"I think our IQ was definitely off the line just now. ”

"Uh...... I feel the same way. Sora Akiyama touched his chin with a slightly embarrassed expression.

They rang the doorbell in front of the second-floor door. A moment later, Yuta Tomigashi came out and opened the door.

"Good morning, Tomigashi. ”

"Akiyama-kun and the Seven Palaces...... Good morning, come in and sit. ”

As soon as Nanamiya Tomoyin entered the door, he said that he had something to do with the little bird You Liuhua, and the two girls went directly into the bedroom and slammed the door shut. Zhangye went out for an event today, leaving him and Yuta Tomigashi staring dryly in the living room.

"What are they doing here?"

"Well, to be honest, I don't know. Akiyama thought about it for a moment and took the initiative to open the topic, "Well, Tomigashi-kun, your line drawing is pretty good." ”

"That...... It's okay, just draw casually. The other party's face was slightly red, obviously remembering some bad black history.

"Ha, what's the humility, show you something good. He smiled and handed the tablet over.

"It's ...... edges2cats?

"Recently, an open-source application has become popular, which can automatically fill in and generate a 'real picture' based on monochrome line drawings. The one I'm showing you is the version of the drawing cat. ”

"Eh, I'll try!"

Yuta Tomigashi took the brush from his hand and sketched a squatting cat with a brush. Then, with a tap on the "process" button, the rough line drawing instantly turned into a living cat, almost like a photograph.

"Oh, that's amazing!" exclaimed, "How?"

"A method of machine learning, conditional generative adversarial networks. To put it simply, a [generator] is trained, the former receives the input line art and outputs an image, and a [discriminator], which compares the line art with other images, including the output image, and tries to discern whether the image was generated by the generator. Eventually, the trained network will reach Nash equilibrium. ”

Akiyama Sora smiled self-deprecatingly when he said this: "My painting level is really not good, and I guess I can only draw cats." Other versions of the software are already on the line, and in addition to drawing more topics such as buildings and shoes, they also include coloring black and white images and generating dynamic scenes. ”

In fact, such adversarial networks can also be used for "image super-resolution" – the recovery of a high-resolution image from a low-resolution image or sequence of images. It's a pity that because the algorithm he came up with some time ago based on the "computer knowledge" of his previous life is much more powerful than this, not many people pay attention to this application.

The "computer" of the spirit clan in my memory does not use integrated circuits, but uses something called "integrated spirit path", which is similar in principle but much more powerful. However, this technology relies on the physical laws of that world and cannot be reproduced on Earth. In addition to this, the Spirit Race has another intelligent structure that he now has that is difficult to understand, and can directly calculate chaotic processes without an approximation.

"By the way, since it's open source, there should be code, right?"

"Well, on another web page, it's called pix2pix. But this thing burns the graphics card.,It's okay to run on the desktop.,Forget about the notebook.。 ”

After all, considering the problems of power consumption and heat dissipation, the upper limit of the graphics card power of desktop computers is much higher, so both of them burn desktops, and laptops can work and play lol or something. What he didn't tell the other party was that conditional generative adversarial networks are difficult to train, and that there needs to be good synchronization between the generator and the discriminator.

At this moment, Tomoon Nanamiya and Torokuka Tori came out of the room, and the former winked at him, and it seemed that everything was going well. Seeing that Yuta Tomigashi was ready to go back to the room to run the procedure, Sora Akiyama tugged at her clothes and signaled that it was almost time to go.

"Well, let's go back with nothing. ”

"Hmm. ”

(Saturday, September 21, 2013, noon; 4th floor, Sora Akiyama)

"Great! Yesterday they had a pretty good conversation!"

As soon as Nanamiya Tomoin entered the house, he couldn't wait to tell him about it.

"In other words, the incident of contradictions and fierce quarrels between the two people in the parallel world has been avoided?"

"Hee-hee, that's not all...... "The other party blushed slightly and leaned over with a wicked smile, "They slept together last night." ”

"Hey, hey, this kind of thing isn't suitable for casual listening, right?" Akiyama was stunned for a moment.

"Haha! Where did Akiyama go?" Nanamiya Tomoyin's arms wrapped around his neck, "Actually, they were telling each other to clear their bowels until late at night, and they fell asleep in a daze." ”

Looking at the girl who was close at hand in front of him, exhaling like an orchid, he suddenly felt a little hot in his body, and there seemed to be a cluster of flames in his heart that wanted to dance with joy. He reached out and hugged the other party's slender waist, so that the two of them fit together, and buried his head in the green silk to smell the fragrance. The girl writhed restlessly in his arms, then leaned into his ear and whispered, the heat of her exhalation moistening her ears a little.

"Did Akiyama ever think about eating someone?"

Akiyama Sora was startled when he heard this, and when he looked up, he saw that Nanamiya Tomoin was looking at him gently, his face flushed. The atmosphere of the scene suddenly became charming.

"What, this...... This topic...... Well, I admit, thought about it. "And I built a model, and by the way, I reviewed the anatomy." ”

"Poof...... Hahaha!" The other party was amused by his words, and gently hammered him with his pink fist, "It's really Akiyama's style!"

"My mind is structured like this...... Hey, what kind of eyes are you looking at...... Don't you know that not only boys have sexual fantasies about the girls they like, but girls also have sexual fantasies about the boys they like. ”

As soon as the words fell, Qigong Zhiyin's face turned red and he couldn't speak. Sora Akiyama hugged the girl who was stuck in shyness, feeling the touch of the other party burying his head in his arms. It was a long time before the girl looked up, the blush on her face not yet completely fading.

"Now, I feel like Sophia has completely fallen...... "Nanamiya Tomoyin has a shallow smile on his face, "but I really like this feeling." ”

"Well, I'm really happy when I'm with Nanamiya. He flicked the tip of the other person's nose affectionately, "Okay, it's not early, it's time to prepare lunch." ”

Lunch consists of shrimp porridge with a plate of boiled vegetables. The two of them worked together and quickly cleaned the rice and cut the ginger, shallots and coriander.

The shrimp were bought this morning and the meat is firm and absolutely fresh. Sora Akiyama and Tomoon Nanamiya break off the shrimp head, pull out the mud line, remove the tail spines, and finally cut the whole shrimp along the back.

While marinating the shrimp and making porridge, he boiled the oil pot, threw in the shrimp head, and fried it until golden brown. Seeing that the time was almost up, he opened the lid of the pot, put the shrimp meat, ginger, shallots and coriander, and fried shrimp heads into the pot, and boiled until the porridge became sticky before turning off the heat. On the other side, Tomoyin Nanamiya has cooked the vegetables and dressed them in sauce.

This delicious porridge whetted the appetite of the two, and each poured more than three bowls. After lunch, they take a break to start a new round of lessons.

"Biology is much easier to understand than mathematics, physics and chemistry. In addition to the idea of experimental design and verification, most of the difficulty lies in how to memorize. My advice is to brainstorm and think of relevant knowledge at any time in your life. ”

Sora Akiyama pointed to the electronic textbook in Tomoon Nannomiya's hand: "MiRNA is an RNA molecule about 21 to 23 nucleotides long that is widely present in eukaryotes, and regulates the expression of other genes...... We only ate vegetables at noon, right?"

"Well, but what does this have to do with mirna?"

"The mirna of plants and animals differ in three ways. First, the genes encoding miRNAs are located differently in the genomes of animals and plants, secondly, the synthesis process of miRNAs in animals and plants is different, and thirdly, the mode of action of plant miRNAs is different. Recent studies have shown that plant miRNAs can be digested and absorbed into the bloodstream, where they can play a role in different target organs. ”

"Eh, there's no way a textbook is so cutting-edge, right?"

"No way, biology is a rapidly evolving discipline. Strictly speaking, modern biology only became a science after the discovery of the DNA double helix structure. He rubbed the other man's hair, "Remember what you and Mori-sama studied in Potions? ”

"Ah...... Well. I mean, that's an exaggeration, isn't it?"

"Haha, don't worry. The next content is from "CellResearch", which Xu Mingshan mentioned to me recently. Honeysuckle is believed to have the effect of clearing heat and detoxifying in Kampo medicine, and is often used to treat wind-heat colds. Remember the naming convention of the mirna, the number followed by the prefix represents the order of naming. Studies have found that MIR2911 is still stably present in honeysuckle decoction after decoction, while mouse experiments have proved that oral honeysuckle decoction or synthetic MIR2911 can effectively resist the invasion of a variety of influenza viruses, including H1N1. The experiment of the control group was to add miR2911 antagonist to the honeysuckle decoction, and then found that its efficacy was greatly reduced. ”

"Well, in other words, the researchers have confirmed the medicinal effect of honeysuckle in Kampo medicine. Then the next step is to explain the principle, right? with a different theory than Potions. ”

"Absolutely. MIR2911 specifically inhibits the expression of two important proteins of influenza virus, PB2 and NS1, thereby hindering virus replication. Pharmacokinetic studies have shown that elevated MIR2911 can be detected in the blood circulation and lungs of mice, and target organs have been identified. The specific experimental design is quite interesting......"

In fact, Xu Mingshan first read a review of the popular science article in "The Chemistry of Life", and the rest of the part was found by Akiyama Sora following the references. He used this research as a starting point to help Nanamiya Tomoyin go through the replication, transcription, translation and regulation of genes - the specific details are not very dead, because there is no need for this. It was already four o'clock in the afternoon after the class, and the two of them decided to go to the gym of Duanshan Shuji to exercise for a while, and by the way, they were addicted to cold weapon fighting.
