107 journals of "Biology Biology" were withdrawn from Chinese authors' papers. Some people have raised a question that has stumped me: "It is said that the pressure of assessment and indicators is the same at home and abroad. Why are foreign authors not being drafted on a large scale? â€
I was asked to be stunned. The first reaction is very emotional: how can anyone do this in foreign countries, looking for death?
Rong Yongqi, a scientist who works in a cancer hospital in the United States, told me: "If you are discovered, you will have nothing."
Of course, things will not be so absolute. There are always people who can't stand the temptation to take shortcuts. One data is that in the US research community, the average proportion of scientific misconduct is estimated to be one in 100,000.
What kind of atmosphere is the probability of misconduct so low? Rong Yongqi said that when he went to the No. 1 Children's Cancer Hospital in the United States more than 10 years ago, "You said that you have a qualification in China, and no one will doubt it." For papers that require peer review, the researchers will not spend time verifying the original experimental data—until these two years, there are artificial fakes.
Corresponding to this kind of trust atmosphere, the cost of academic misconduct is enormous.
"Once the falsification, people who are still doing research work will not be allowed to apply for funds for life, and even the funds already issued will be recovered. If they have already found a job, they will lose their jobs. In fact, they can no longer do research. Rong Rongqi said.
However, this severity did not begin at the moment of the incident. The feeling in the United States is that the persistence and emphasis on "credit" permeates all aspects of academic life: the lectures of each course in the university entrance are printed with an "honor guarantee" that reminds students to abide by academic norms. My husband, Lao Chen, who is a graduate student, had a correct answer to a mid-term assignment in a class last year, but only got 20 points. When looking for a teacher to discuss, the other person pointed to a certain page in the homework and asked seriously why "the operation of these lines Is it similar to another classmate?†An undergraduate student who graduated from Harvard University in Atlanta had applied for a number of medical schools last year, even if there was a strong guarantee from the professor, because of the experience of arbitrarily forging professors during school. Did not get an offer letter.
We may have heard of the Zoom Bullet Camera, so what is the Zoom Bullet Camera/ Bullet Zoom Security Cameras/ Bullet Zoom Digital Cameras/ Smart Zoom Bullet Camera/ Zoom Lens Bullet Cameras/ Zoom Bullet Camera HD? We know that the Bullet refers to the camera shape, so what about the Zoom? Actually, the Zoom refers to a type of the camera lens. Today let me introduce the camera lens for you.
I have introduced the camera lens and 2 classifications for you before. Today please let me introduce another parameter of the camera lens for you---the Wide Dynamic.
So what is the Wide Dynamic?
The Wide Dynamic actually refers to the brightness ratio of the brightest and darkest parts of the image that the user can see at the same time via the camera. The Dynamic Range broadly refers to the changing span of a changing thing, that is, the range from the lowest point and the highest point of its changing value, which is usually described as the difference between the highest point and the lowest point. Well, the Ddynamic Range of a camera refers to the ability of the camera to adapt to the light reflection of the scene in the shooting scene, specifically the range of brightness (contrast) and color temperature (contrast); which means the camera's adjustment range of the "darkest" and "brightest" of the image, or the ratio of the lightest tone to the darkest tone in a still image/video frame. And the hue can show the precise details in the image or frame. As the ratio of the two tones, the unit of the dynamic range can be decibels, bits, files, or simply expressed as a ratio or multiple.
The Wide Dynamic Camera Technology is a technique by which the user can see the characteristics of the image under very strong contrast via the camera. In some occasions where the contrast between light and dark is too large, due to the limitation of the CCD's photosensitive characteristics, the background of the captured images will be easily too bright/the foreground of the captured images will be easily too dark. Later, Because of the wide dynamic technology emerged, and this problem has been solved.
So how about the applications of the Wide Dynamic Camera?
The Wide Dynamic camera is usually applied when the light environment is still ideal but the details of the target object cannot be obtained. That is to say, the wide dynamic technology is mostly used in places where light and dark alternate. When the surveillance camera cannot achieve low-illuminance monitoring, the wide dynamic technology needs to be used to "fill the light". In terms of the surveillance camera applications, the ordinary surveillance camera captures the images with the clear background but the dark foreground, while the wide dynamic camera can capture the images with both the clear foreground and background.
The Wide Dynamic Camera is usually applied to the Highway toll system, the Electronic police system, the City Commercial Street and so on; which is very useful and has brought much convenice to our life.
In a word, I hope that the introducton of the Wide Dynamic can make all of us know more about the Zoom Bullet Camera and the whole video monitoring field.
