2 . Ancient documents are an important part of ancient civilization. Unfortunately, such documents are often vulnerable (易受……伤害的) to aging and related damage, which greatly reduce their legibility (易读性).
An international group of computer scientists have teamed up to strike up the conversation with ancient people through their writing that have been broken down by time. They have developed a computer-assisted method to help us have a conversation with people from the distant past.
Appreciating ancient documents, even when in good condition, can require a reader to dig into the role of a cryptologist (密码学家). That’s because the combination of a writer’s handwriting legibility, lettering styles, old-fashioned spelling and grammar conventions or abbreviations (缩写) can make even a native language seem unfamiliar. Besides, the same document’s legibility can be reduced even more by faded ink, widened lettering due to exposure to wetness, and so on.
Typical digital reconstruction changes a document into black text on a white background in an attempt to reveal the text through noise filtering (过滤) and contrast improvement. However, in this current method, the image is much more of a restoration effort, keeping much of the look and virtual feel of the document.
Researchers applied a complex integration of several digital color interpretation techniques and Gaussian mixture models to identify and separate features of text, paper, and historical objects. This allows for the specific selection of different layers of information based on slight spectral (光谱的) differences. So a user could decide whether a notation (符号), page decoration, coffee mug ring stain or another feature was critical to the understanding by adding or removing layers.
In some cases, the technique could preserve features that would otherwise be lost, such as the vague watermarks of a paper manufacturer, which could offer vital insights to historians. “For example, Leonardo da Vinci’s famous works were written on pages with watermarks from various paper suppliers that allowed document historians to group them into likely writing periods,” said Usman Habib, an expert on digital restoration.
According to the paper, the processing can be accomplished on a standard desktop computer, and it takes just a few minutes. This would make it a great tool for historical document researchers and people attempting to figure out old family recipes.

3 . Many people love the Halloween season, particularly young ones. It’s not hard to understand. The Halloween season is a time for fun-sized candy, giving rocks to trick or treaters, apple cider donuts, and frights. The very last-frights, are generally all in good fun. But can they be dangerous? Can someone be scared to death?
The key factor in an imagined scare-caused death is a little chemical that anyone who’s played a particularly intense game of hide-and-seek is very familiar with: adrenaline (肾上腺素). Fear puts the body in a state of severe emotional anxiety, which in turn causes the autonomic fight-or-flight response.
The fight-or-flight response is an evolutionary defence mechanism (机制) which acts in your best interest when there is a noticed threat. You sweat a lot, your anxiety is exacerbated, your blood glucose (葡萄糖) levels are increased, and your heart rate is higher. Like a cornered animal, you’re a bit less reasonable, a bit stranger, but a bit more ready to survive.
Now, back to the adrenaline. Adrenaline causes all of these processes, but there’s just one organ, which, if overloaded, can lead to sudden death. The human body doesn’t immediately come to an end as soon as a kidney (肾) fails, but when a heart stops working, the whole business fails. This is what happens to your body during an adrenaline rush.
Adrenaline causes calcium (钙) to enter the heart at a higher rate, and when there’s more calcium rushing through the heart, it has harder time resetting to its normal resting rate. This can cause a dangerous condition, which prevents blood from pumping to the rest of the body. Without immediate treatment, this can lead to sudden death.
Of course, such cause of death isn’t unique to being scared. Any event that increases one’s adrenal level could lead to this dangerous condition. So if you are planning on scaring others the next Halloween season, be sure to do it in a controlled setting, especially if you have a history of heart problems.

5 . Tao Yuanming and Henry David Thoreau were both poets, but one lived in Ancient China and the other in 19th century America. Superficially, these two men, whose lives were separated in time by nearly 1,500 years, were polar opposites. And yet they shared an intense respect for nature, which made them each an influential figure of their time.
Both men made dramatic transformations to their lives in order to reconnect with nature. As an official in the Eastern Jin Dynasty, Tao felt conflicted over life at court. In 405, he quit the service of the court for good, expressing his unhappiness in the now famous line that he would not “bow like a servant in return for five dou of grain”. He spent the next 22 years until his death, working the land in a poor, rural area. From his poetry, we can learn that although his life was arduous, he succeeded in finding contentment in its simplicity and in drawing pleasure from nature.
While Tao’s return to nature was a reaction to a lifestyle he was opposed to, Thoreau’s was a personal decision to transform the way he lived. He had a decent quality of life, but he wanted to live in a simpler way. For two years, two months and two days, he lived in a cottage in the forest on the edge of Walden Pond, focusing on himself and his writing. He explained his reason for doing so in Walden: “I went to the woods because I wished to live deliberately, to front only the essential facts of life.” Both men were happy to withdraw from contemporary life, seeking a harmonious relationship with nature in the quietness of their lives.
Although Tao and Thoreau do not treat nature in quite the same way, their works show its beauty and value. Tao’s nature is a place of fields and villages, in other words, rural, and his animals are domestic ones, such as chickens and dogs. The calm and peaceful life he wrote about is in contrast to and critical of the depressive court life.
Thoreau’s descriptions of nature emphasized the beauty and purity of the wild areas around him. Devoting himself to observations of the natural phenomena, he recorded his detailed findings in his journals. Thoreau’s writing aimed to convince people that animals and plants had a right to live and prosper, as we do. We should live with them in harmony and enjoy nature’s gifts.
It takes considerable courage to reject the easy and familiar and instead try to live closer to nature, as both Tao and Thoreau did. Their choices led them to quiet and reflective lives with fewer material desires. In today’s modern world, their ideas about living simply and being at ease with nature may take us a step closer to attaining personal well-being and fulfillment.
