Let’s talk about it here today. Technology last night and this morning. See you next week.

The progress of domestic cars in recent years is visible to the naked eye. With the development of car manufacturing technology, the quality has also come up. The development of intelligent technology has made rapid progress, and it has also obtained a higher voice over in the new competitive track. The configuration materials are more willing to pay, but the pricing is more realistic. Therefore, if you pursue high cost performance, there is no reason not to choose domestic cars.

For young people, the pursuit of cost-effective car at the same time, but also the pursuit of fashion and sports personality, so the starting price of less than 100,000 Changan Auchan X5 PLUS and Geely Colorful COOL become their popular choice. As for who is more worth buying options, we look for answers from the comparison.

But before the comparison, there is a key information that must be mentioned. At present, Auchan X5 PLUS provides large-amount factory discounts with cash down to 11,000 yuan, that is to say, it only needs 80,900 to start, which is undoubtedly very sincere for a sports SUV with strong comprehensive strength. Colorful COOL currently only provides car purchase policies such as 7,000 yuan discount, which is not as strong as the direct cash discount of Auchan X5 PLUS. So from the perspective of the entry threshold, Auchan X5 PLUS is already the next city.

Power chassis comparison: Auchan X5P LUS is more forcibly updated and stable

Auchan X5 PLUS and Colorful COOL are both the positioning of sports SUVs, and the main groups they face are young people. But what is sports and what is the dish of young people should not just look at appearance, but also look at strength.

Auchan X5 PLUS is equipped with Blue Whale’s new generation NE1.5T high-pressure direct injection engine + Blue Whale 7-speed wet dual-clutch transmission combination. Colorful COOL is only equipped with 1.5TD engine + 7-speed wet dual-clutch transmission combination on high-end models. Under the support of greater power and torque, the zero-hundred acceleration of Auchan X5 PLUS is only 7.51 seconds, which is nearly 1 second faster than the high-end models of Colorful COOL, and the power gap can be seen.

In all stages of acceleration, the starting response of the Auchan X5 PLUS is only 360ms, the 0-60kM/h acceleration is only 3.8s, and the 80-120kM/h acceleration is only 5.6s. These results are even better than those of the A-class cars that are the main sports, making the starting, low-speed acceleration, and high-speed acceleration a step faster.

While the power is significantly stronger, the fuel consumption level of the Auchan X5 PLUS is similar to that of Colorado COOL, and the WLTC comprehensive fuel consumption is only 6.25L/100km, which is truly fast and fuel-efficient.

Of course, excellent sports performance comes not only from power, but also from chassis and steering. The Auchan X5 PLUS comes standard with front McPherson/rear multi-link independent suspension, and has undergone targeted adjustment and rigorous road conditions testing, so it has better handling performance and driving quality. The Colorado COOL uses a lower-cost rear torque beam non-independent suspension, which is inherently inferior in handling and comfort. In addition, the Auchan X5 PLUS also uses a three-stage adjustable ESP, which can choose different steering modes according to different driving needs.

In terms of actual driving experience, the Auchan X5 PLUS not only has stronger power output and faster acceleration than the Colorado COOL, but also has less roll in corners and emergency line changes, more accurate directivity, and can enter and exit corners at a faster speed. In the face of road impact, the advantages of four-wheel independent suspension more fully suppress vibration and bounce. In the medium and high-speed area, the chassis feedback of the Auchan X5 PLUS is more textured, and the suppression of wind noise and fetal noise is significantly better. In addition, the brake response of the Auchan X5 PLUS is also more sensitive, with a shorter stroke, which is more in line with the characteristics of sports models.

Space size comparison: the two cars are not at the same level

Young people buying a car not only meet their personal driving and travel needs, but also inevitably have to deal with necessary household and social needs. After all, accompanying family members out, gathering with friends or traveling are all common car scenarios for young people. Therefore, a larger SUV is necessarily a better choice.

Compared with the body size of the Auchan X5 PLUS and the Colorado COOL, the advantage of the former is undoubtedly huge. It can also be seen from the body size that the Auchan X5 PLUS belongs to a compact SUV, while the Colorado COOL belongs to a small SUV, and the two are completely different. Therefore, the riding space of the Auchan X5 PLUS is much more generous, especially the rear space is more stretched than the Colorado COOL, and the luggage compartment space and storage space also show higher practicality.

Although both cars use the design of sports seats, the Auchan X5 PLUS presents a better sense of quality in the materials and craftsmanship of the cockpit. And the unique 30-inch wrapping smart triple screen of the same class forms a more technological atmosphere for the driver. It brings a silky operation experience through the delay-free three-screen interactive interface switching. For example, when encountering a corner to trigger the panorama, the navigation will automatically project the screen to the instrument screen, which is more intuitive and safe; the linkage of cockpit lights, sound effects, seats, etc., can also make the car change into a KTV, gym, game hall in seconds. In addition, because the Auchan X5 PLUS has improved NVH performance at 115 places in the whole car, the silent feeling in the car is far beyond what we expect from 80,000-class SUVs.

With more space, a higher-quality interior atmosphere, and four-wheel independent suspension, the Auchan X5 PLUS can undoubtedly provide a more comfortable driving experience. In contrast, Colorful COOL pays more attention to individuality, while ignoring comfort and practicality to a certain extent, and there are fewer applicable car scenarios.

Differential configuration comparison: both parties have their own advantages

In order to fully reflect the respective configuration advantages of the two cars, we selected the top model for comparison. The two models are Auchan X5 PLUS 1.5T Smart Fun AI Edition and Colorful COOL 1.5TD DCT Battle Edition.

The advantage of Colorful COOL’s differential configuration lies in intelligent driving assistance. Compared with the Auchan X5 PLUS, it has more intelligent driving functions such as parallel line assistance and lane keeping, and the matrix headlights can automatically adjust the far and near light. However, from the perspective of daily driving, many intelligent driving functions are actually not used frequently, and since the Auchan X5 PLUS is also equipped with common intelligent driving functions such as ACC adaptive cruise and 540-degree panoramic images, the difference in car experience is not big.

It is worth mentioning that both vehicles can achieve intelligent parking, intelligent tracking and reversing, and remote parking, but the EaglePilot full-voice automatic parking system equipped with the Auchan X5 PLUS is more intelligent, capable of voice control in addition to key remote control and mobile phone remote control.

The difference in configuration advantage of the Auchan X5 PLUS is in terms of intelligent interaction. It is equipped with the OnStyle 5.1 smart happy cockpit, which has a higher level of intelligent performance. One of the more obvious advantages is that the Auchan X5 PLUS can not only realize intelligent voice control in the car, but also realize full-scene intelligent voice outside the car. For example, saying "X5 drive the car out" outside the car can automatically park out of a narrow parking space, which greatly increases the convenience of using the car.

And through the FaceID 3.0 car internal and external facial recognition system, you can unlock the vehicle by brushing your face outside the car. Through facial recognition, gesture recognition, intelligent voice and other technologies, we have also created a variety of personality scenes such as Mai-free KTV, Auchan Fitness, Auchan Travel, one-click rest for main and co-pilot, and track mode, allowing users to feel more intelligent fun in the car.

In comparison, the intelligent interaction functions of Colorful COOL are more conventional. In-car intelligent voice, three-finger flying screen, audio-visual entertainment, and mobile phone remote control are basically all, and these functions can also be fully realized on the Auchan X5 PLUS.

In terms of comfort configuration, the two cars are not much different, both belong to the superior level of SUVs at the same price, with panoramic sunroof, keyless entry/start, wireless charging of mobile phones, induction wipers, automatic air conditioning, etc. The subtle difference is that the Auchan X5 PLUS has Sony stereo, hot and cold temperature control armrest box, external rearview mirror memory/reversing automatic down-turn, induction trunk, etc., providing a more comprehensive comfort experience, while the Colorful COOL is slightly superior in seat functionality because it is equipped with front seat heating.

Overall, the configuration of both cars is very high, but from the perspective of vehicle usage and value, the Auchan X5 PLUS is still better. Especially in terms of intelligent interaction, the leading intelligent technology of the Auchan X5 PLUS brings more convenience and fun to use the car, showing a higher sense of value in the context of the technology era.

Write at the end:

Auchan X5 PLUS and Colorado COOL have a lot of overlap in price, and both focus on sports and intelligence, thus forming a direct competitive relationship. But in contrast, it is not difficult to find that the Auchan X5 PLUS power chassis performs better and is a more sporty side; the intelligent interaction experience is also more advanced and is a smarter side. In more dimensions, Auchan X5 PLUS has a huge advantage in space size and a more comprehensive configuration, which can well balance comfort and practicality. So on the whole, Auchan X5 PLUS’s product strength is obviously stronger. Coupled with the large cash discounts currently launched by manufacturers, the cost performance is much higher than Colorado COOL, which is obviously a more worthwhile option.

Recently, the dance of "Subject III" has become popular online and offline, and more and more people are attracted by it, which makes the dance quickly change from "dirty" and "questioned" to popular in many places and even attract attention abroad.

The dance of "subject three" rose in Guangxi earlier. Why is it called "subject three"? There is a network saying that every Guangxi person has to go through an exam in his life. If it is likened to driving test, then "subject one" means singing folk songs, "subject two" means talking about powder, and "subject three" means dancing, so the dance had the network name of "subject three in Guangxi" in its early days.

The author believes that the four characteristics of "Divine Comedy", minimalism, "open source" and platform have jointly contributed to the popularity of "Subject III" dance.

First, the adaptation of Divine Comedy makes dance and music complement each other. The classic BGM (background music) of "Subject III" dance is "Laughing at the Rivers and Lakes" (DJ version). The style of this song expresses a kind of heroism, optimism and self-confidence in the face of setbacks and failures, encourages everyone to face setbacks bravely and frankly, and inspires people’s courage and lofty sentiments. The DJ version of the music is lively and dynamic, and with the opera singing method, the lively and joyful atmosphere is quickly created between the music, which is easy to arouse the emotional resonance of onlookers.

Second, the minimalist action catalyzes innovation. Every movement of this dance is very simple, and ordinary people can master it after practicing several times. In addition, dancers can innovate anytime and anywhere, without special knowledge reserves and professional training, and zero-based fans can also arrange new moves. According to rough statistics, dozens of dance versions of "Subject III" have appeared on the vibrato platform at present, and they are still growing.

Third, "open source" is versatile and ever-changing. The performance threshold of "Subject III" dance is extremely relaxed, which provides a friendly "open source" environment for subsequent scene changes. As far as the number of performers is concerned, the dance can be performed by a single person or by a group of people. As far as the performance scene is concerned, the dance has low requirements for the performance location. As far as performance assistance is concerned, the dance can be adapted to a variety of costume props. As far as the performance effect is concerned, the movements are concise, smooth and large, especially with the constant change of the photographer’s angle of moving the mirror, the road show of this dance has a strong visual impact and shock. As far as the performance content is concerned, under the fierce competition of short video content and the situation of "involution", various creators have "crossed the sea" and "opened their brains wide" and rushed to release creative short videos, adding various storylines on the basis of dance, in order to win the valuable "second-level" attention of the audience.

Fourth, the short video platform enables sustainable development. The short video platform, represented by Tik Tok, integrates advanced digital technologies such as big data and virtual reality, integrates many resources such as finance, technology and culture, and opens the way for the production, dissemination and realization of Internet content. This unicorn-style head platform provides a warm soil and appropriate opportunities for the popularity and continuous popularity of the "Subject III" dance.

Of course, there are also some negative voices around the dance of "subject three" Some people think that the artistic value of this dance is low, even vulgar; Some people think that the dance is "too corny" and "spicy eyes"; Others think that such dancing movements may bring some health risks, such as spraining ankles. Such comments are not uncommon, but it is undeniable that such a dance has indeed "harvested" a considerable number of audiences, and has continued to circle in the network tide, and has continued to maintain or even increase its popularity. In the face of this cultural phenomenon, let’s take a cautious and discerning attitude towards it, and get valuable experience and methods through the analysis of removing the false from the true and discarding the bad, so as to provide experience reference and enlightenment for the creation and dissemination of other art categories.

In the current Internet era, although the online literary field presents the development trend of Qian Fan’s competition and a hundred flowers blossom, it also exposes some problems, such as the short life cycle of some literary works, and even "seeing death"; Some literary and artistic film and television works are applauded in the industry, but the market response is flat, and there is an embarrassing phenomenon of applauding and sitting upside down; Although some traditional excellent cultural works still have market competitiveness, they are limited by the lack of appropriate communication channels, which hinders their communication. In view of this, the continued popularity of "Subject III" dance may provide some solutions to the above problems.

There should be both upward intention and downward brushwork in creation. Since ancient times, excellent literary works must be upward and sublimated, which is consistent with people’s pursuit of truth, goodness and beauty. Low conception is like unstable foundation and broken roots, even with superb creative skills or gorgeous rhetoric, it can’t make it have classic characteristics. With a good idea, how to show it? This requires a downward stroke. Literary and art workers should often go deep into the lively scene, explore the first-hand materials, and carry out accurate screening, deep processing and classic empowerment to create excellent literary and artistic works with both local flavor and vitality.

In expression, we should constantly update the "thesaurus version" to adapt to the current context in time. Literary and artistic creators should first realize the necessity and importance of keeping pace with the times, then follow up in time, study moderately, master skillfully, and finally integrate, digest and absorb according to their own creative characteristics, so as to narrow the psychological distance and physical distance between their works and young people, thus increasing the audience depth of literary and artistic works.

In communication, we should constantly be compatible with new media and inject surging power into the spread of literary and artistic works. In the digital age, the digital platforms represented by Tik Tok, Aauto Quicker, Xiaohongshu, Bili Bili, etc. have shown strong advantages of being late-comer. They are extremely fast in spreading, easy to enter the threshold, and low in cost. They are rich in content, low in cost, convenient and simple, and quick to realize. They are quietly and rapidly changing our way of life and production. Faced with this trend, literary and art workers should also know the situation in time, change their development ideas, adapt to the new digital track, learn relevant successful experiences, start from imitation, accumulate in exploration, improve in resumption, become bigger and stronger in innovation, and inject strong impetus into the spread of literary and art works with the unique advantages of digital platform.

Super Long Wheelbase 2018 New Volvo s90 Group Purchase Latest Quote T5 Zhiyuan Edition

In terms of appearance, Volvo S90 adopts the latest family-style front face design, and the straight waterfall air intake grille uses the concave design. The headlights of Thor’s Hammer are very sharp. The "C"-shaped taillight has a high recognition, and the exhaust hole is flat-mouthed, and it has a layout of two outlets on both sides. In terms of body size, its length/width/height are 4963×1890×1443mm and its wheelbase is 2941mm, respectively. Why is S90 cold? Even if people lengthen the wheelbase, they don’t add a tacky "L" at the back of the trailer like other competitors. It’s just called the long-axis version, with a little pride in it.

The extension of the wheelbase will inevitably affect the change of space. The wheelbase of Volvo S90 long-axis version has increased by 120mm, although it has only exceeded the numerical value, but the actual space experience is still excellent. The legroom in the back row is obviously much better than that of imported models with standard wheelbase, which conforms to the positioning of domestic luxury intermediate models.

In terms of safety configuration, the new car will come standard with City Safety urban safety system, including ACC adaptive cruise, distance monitoring, lane keeping, blind spot monitoring, anti-rear-end warning, uphill assistance and so on. At the same time, it has an advanced semi-automatic driving system called "Pilot Assist", which can give gentle steering assistance to keep the vehicle running in the lane at a speed of 130 km/h. In addition, the new car will be equipped with an adaptive chassis and an active rear air suspension. The interior can be called a work of art. The typical Scandinavian design and simple brushwork show a picture in which technology, luxury and warmth complement each other.

Times can change people, even car names and historical traditions. It once claimed that only rear-drive and four-wheel drive are now working hard on front-drive models, and it can no longer be distinguished from Volvo’s T4 and T5 names in the future. Volvo S90 long-axis version adopts 2.0T four-cylinder engine, and T4 and T5 models adopt two different adjustment methods of high and low power. The maximum power of T4 model is 140kW/5000rpm, and the maximum torque is 300Nm/1400-4000rpm. The maximum power of the T5 model is 187kW/5500rpm, and the maximum torque is 350Nm/1500-4800rpm. After that, a T8 model will be introduced, which is a hybrid model.

In the early morning of March 5, Beijing time, the team of Professor Chen Yundai from the Cardiology Center of the General Hospital of the Chinese People’s Liberation Army published a special report on clinical research at the American Heart Association/World Cardiology (ACC/WCC)2023 Conference. Based on the artificial intelligence CT-FFR technology, the clinical research report on the treatment and follow-up of patients with stable coronary heart disease -TARGET trial, the results will be published simultaneously in the top international journals.CirculationJournal (TOP journal in JCR 1 area, impact factor 39.9).

The research was supported by the National Key R&D Program and the Beijing Science and Technology Rising Star Program, and combined with the research teams of cardiology and radiological imaging departments of several top domestic third-class first-class hospitals such as Beijing anzhen hospital affiliated to Capital Medical University, the Second Affiliated Hospital of Zhejiang University Medical College, Qilu Hospital of Shandong University, the First Affiliated Hospital of Xinjiang Medical University, and tongji hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology. The correspondent of this research paper is Professor Chen Yundai, Associate Professor Yang Junjie, Deputy Chief Physician Shan Dongkai and Dr. Wang Xi from the Department of Cardiovascular Medicine of PLA General Hospital are the co-first authors of this paper.

Introduction to research

TARGET study is the first multi-center, randomized and controlled clinical study in the world to evaluate the treatment and management of new stable chest pain patients using the field deployment strategy based on machine learning CT-FFR calculation. The research uses the artificial intelligence CT-FFR computing technology independently developed by China (Keya Medical Technology Co., Ltd.), and a total of 1216 patients from six medical centers in China were selected. The pretest probability of obstructive coronary heart disease in the enrolled patients was medium to high, and coronary CT angiography suggested that there was a critical stenosis of 30%-90%. The researchers randomly divided patients into CT-FFR diagnosis and treatment group (experimental group) or standard diagnosis and treatment group (control group). The main end point of the study was the proportion of patients with non-obstructive coronary artery disease or with obstructive coronary artery disease who did not receive revascularization during the follow-up coronary angiography within 90 days. Secondary end points included major adverse cardiovascular events, quality of life outcomes, improvement of angina symptoms and medical costs.

The results showed that compared with the control group, the proportion of patients with non-obstructive coronary disease or obstructive coronary disease who did not receive revascularization in CT-FFR diagnosis and treatment group decreased significantly (28.3% vs. 46.2%, P<0.001). On the whole, there were more patients receiving revascularization in CT-FFR group than in the control group (49.7% vs. 42.8%, P=0.02), but there was no significant difference in the proportion of MACE during the one-year follow-up (hazard ratio, 0.88; 95%CI, 0.59 to 1.30)。 During the follow-up period, the quality of life and symptoms of the two groups were similar, while the medical cost of CT-FFR treatment group tended to decrease. It is concluded that, compared with the standard diagnosis and treatment strategy represented by cardiac stress examination, the on-site deployment of CT-FFR calculation diagnosis and treatment strategy based on machine learning will significantly reduce the proportion of patients who have found non-obstructive coronary artery disease or do not need intervention within 90 days after coronary angiography. In addition, CT-FFR diagnosis and treatment strategy tends to save medical costs and increase the proportion of revascularization in the selected population. At the same time, CT-FFR strategy is consistent with the traditional path in improving patients’ symptoms or quality of life and the incidence of major clinical adverse vascular events.

Research enlightenment

TARGET research results show that "CT-FFR strategy based on machine learning in the field is feasible, safe and effective".

In the past 10 years, the extensive use of coronary CTA has promoted the diagnosis and treatment process of coronary heart disease in China. According to statistics, in 2017, the total number of coronary CTA angiography examinations in China reached 4.6 million. Therefore, the simple diagnostic function of coronary angiography is weakening, but among the patients who have received coronary angiography in China, most cases have not found obstructive coronary stenosis in the catheter room. Part of the reason for this phenomenon is that functional examination is not widely used or advanced cardiac imaging technology is not available enough. TARGET study further emphasizes that coronary angiography should only be applied to those patients who are most likely to have obstructive coronary stenosis or benefit from revascularization, and CT-FFR strategy will significantly optimize the management of stable coronary heart disease population.

This study adopts the CT-FFR simulation calculation technology-deep pulse fraction independently developed by Keya Medical Technology Co., Ltd., uses deep learning technology to evaluate the physiological function of coronary artery, and uses artificial intelligence technology to evaluate the FFR of coronary angiography image, which is a deep learning technology independently developed and optimized based on the latest development in the field of computer vision. It can quickly and accurately analyze the non-invasive blood flow reserve fraction. In January 2020, this technology was approved as the first NMPA artificial intelligence medical device class III certificate in China, and now it has become the only CT-FFR product in the world that has been triple-certified by NMPA in China, CE in the European Union and FDA in the United States.

Pamela Douglas, MD (Duke Clinical Research Institute, Durham, North Carolina), former president of ACC, led the experiment funded by HeartFlow (PLATFORM and PRECISE research). She pointed out that the most outstanding thing about the TARGET experiment is the novelty of its on-site CT-FFR analysis.

It is indeed possible that the field deployment method is cheaper and can return the results faster. In clinical practice, if CCTA is used as a first-line test, Douglas said, then the question becomes: "If you have borderline lesions, what should you do next?" For her, "this is a little obvious, because CT-FFR is only a software analysis. Although the previous products are very complicated, it is not without risk to make an appointment for a load test and ask the patient to come back later."

It is very important to deploy artificial intelligence computing in the field of TARGET research. "The advantage of using artificial intelligence algorithm is that it provides the possibility of field deployment, avoids the need to transfer sensitive medical data, shortens the calculation time and increases the participation of clinicians." They explained that although FFR can also be calculated by field computational fluid dynamics, this strategy is complex and requires a lot of resources. The convenience of machine learning will contribute to the application of CT-FFR in a wider range of scenarios, adding that "on-site CT-FFR strategy is practical and may be more suitable to meet the clinical practice needs in various clinical environments."

AIoT intelligent internet of things is artificial intelligence internet of things. AIoT is the abbreviation of AI Artificial Intelligence and IoT Internet of Things. It is an artificial intelligence Internet of Things that collects a large amount of data from different dimensions through the Internet of Things and stores it in the cloud. Based on big data analysis and AI and other technologies, it realizes the digitalization and intelligence of everything. Artificial intelligence is a subject that studies how computers can simulate people’s thinking processes and intelligent behaviors. It is based on bionics, the improvement of algorithm model and calculation speed, and the commonality between human neurons and computer doors (doors are the basic unit of computers). Its strength lies in its learning, reasoning, thinking, planning and other abilities, which ordinary intelligent machines can’t do.

The embedded Internet of Things needs to learn a lot, so don’t learn the wrong route and content, which will lead to a salary failure!

Share a data package for free, almost over 150g. The learning content, face classics and projects are relatively new and complete! It is estimated that it will cost at least dozens to buy some fish.

The Internet of Things refers to the real-time collection of any object or process that needs to be monitored, connected and interacted through various devices and technologies such as information sensors, radio frequency identification technology, global positioning system, infrared sensors, laser scanners, etc., and the collection of all kinds of required information such as sound, light, heat, electricity, mechanics, chemistry, biology, location, etc., and the realization of ubiquitous connection, identification and management between things and people through various types of network access. Through this definition, we can feel that this will be a huge database, and the learning process of artificial intelligence also needs a lot of data information. Obviously, this is a link between artificial intelligence and the Internet of Things, which can link them together and play a greater role.

In short, the Internet of Things (IoT) uses terminals with different protocols to carry out information interaction and intelligent processing through a certain agreed protocol, while artificial intelligence can keep learning and become more and more intelligent with data. If artificial intelligence is software, it needs the Internet of Things as a carrier, and if it is hardware, it needs artificial intelligence to drive it. Therefore, we can also regard the Internet of Things as a carrier of artificial intelligence.

The Internet of Things is an important part of the new generation of information technology. The English name is "The Internet of things". Therefore, as the name implies, "the Internet of Things is the Internet of Things". This has two meanings. First, the core and foundation of the Internet of Things is still the Internet, which is the expansion and expansion network based on the Internet. Secondly, its clients expand and expand between any goods, and exchange and communicate information.
