UNEARTHED: REMAINS OF THE EARLIEST KNOWN
TSUNAMI VICTIM
By Charles Choi | October 25, 2017 1:00 pm
Paragraph 1 Tsunamis have claimed hundreds of thousands of lives in the past two decades. Now a new study finds that a 6,000-year-old skull may come from the earliest known victim of these killer waves.
Paragraph 2 The partial human skull was discovered in 1929 buried in a mangrove swamp outside the small town of Aitape Papua New Guinea, about 500 miles north of Australia. Scientists originally thought it belonged to an ancient extinct human species, Homo erectus. However, subsequent research dated it to about 5,000 or 6,000 years in age, suggesting that it instead belonged to a modern human.
A Rare Specimen
Paragraph 3 The skull is one of just two examples of ancient human remains found in Papua New Guinea after more than a century of work there. As such, archaeologists wanted to learn more about this skull to elucidate how people settled this region.
Paragraph 4 The scientists went back to where this skull was found and sampled the soil in which it was discovered. They focused on details such as sediment grain size and composition.
Paragraph 5 In the sediment, the researchers discovered a range of microscopic organisms from the ocean known as diatoms. These were similar to ones found in the soil after a 1998 tsunami killed more than 2,000 people in Papua New Guinea — for instance, their shells of silica were broken, likely by extremely powerful forces.
Paragraph 6 These diatom shells, combined with the chemical compositions and the size ranges of the grains, all suggest that a tsunami occurred when the skull was buried. The researchers suggested the catastrophe either directly killed the person or ripped open their grave.
Paragraph 7 Tsunamis, which are giant waves caused by earthquakes, volcanic eruptions or underwater landslides, are some of the deadliest natural disasters known. The 2004 tsunami in the Indian Ocean killed more than 230,000 people, a higher death toll than any fire or hurricane.
Paragraph 8 The site where the skull was found is currently about 7.5 miles away from the coast. Still, the researchers noted that back when whoever the skull belonged to was alive, sea levels were higher, and the area would have been just behind the shoreline.
Paragraph 9 The waves of the tsunami that hit Papua New Guinea in 1998 reached more than 50 feet high and penetrated up to three miles inland. “If the event we have identified resulted from a similar process, it could have also resulted in extremely high waves,” study co-lead author Mark Golitko, an archaeologist at the University of Notre Dame in Indiana and the Field Museum in Chicago.
Paragraph 10 These results show “that coastal populations have been vulnerable to such events for thousands of years,” Golitko said. “People have managed to live with such unpredictable and destructive occurrences, but it highlights how vulnerable people living near the sea can be. Given the far larger populations that live along coastlines today, the potential impacts are far more severe now.”
Paragraph 11 Golitko plans to return to the area over the next few years “to further study the frequency of such events, how the environment changed over time, and how people have coped with the environmental challenges of living in that environment.” He and his colleagues detailed their findings Wednesday in the journal PLOS O.

Consider the figure below.
The correct way to describe the main concepts showing by the figure is:
Forensic computer analysts investigate crimes against computers, such as hacking, as well as crimes involving computers. They might search a suspect’s computer hard drive for incriminating files, pictures or other documents. They might also track the Internet activity of a suspect or victim to determine what sites he visited and whom he communicated with. In addition, they can often reveal information that suspects have attempted to hide, such as determining where an email or other electronic communication originated from even if the sender concealed his computer’s IP address to mask his location.

There are specific types of systems analysts, such as systems architects or systems designers, but a systems analyst generally works in the computer department of a company providing the research and information necessary to maintain an up-to-date computer system. The main responsibility of a systems analyst is to make certain the computer system of his or her employer is functioning efficiently. To do this, a systems analyst may examine both the hardware and software currently being used and suggest or even design new programs to better meet the organization’s needs. In most cases, the systems analyst would also provide a cost-benefits analysis to make certain any proposed changes were fiscally responsible.

Asem Hasna lost his leg in Syria – now he’s 3D-printing a second chance for fellow amputees
The story of Refugee Open Ware, and one wounded refugee’s efforts to help his countrymen back on their feet.
For most people, the first time they use a 3D printer is to create a simple object – a fridge magnet or a bookmark. Asem Hasna, then a 20-year-old Syrian refugee in Jordan, began with a prosthetic hand for a woman who lost hers in Syria’s civil war.
Hasna had met the woman in 2014 in Zaatari, the refugee camp 65 kilometers north-east of Amman, the capital of Jordan. The young woman, who has requested anonymity, lost her right hand during an attack and was struggling to care for her two daughters. Hasna, now 23, had just joined Refugee Open Ware (ROW), an Amman-based organisation that taught refugees how to 3D-print affordable artificial limbs for amputees.

A respeito do texto acima, considere as seguintes afirmativas:
1. Asem Hasna teve sua perna amputada antes de completar 23 anos.
2. Hasna, refugiado sírio, tem ajudado seus compatriotas feridos em conflitos confeccionando próteses em 3D.

Computer that reads body language
Researchers at Carnegie Mellon University’s Robotics Institute have enabled a computer to understand body poses and movements of multiple people from video in real time – including, for the first time, the pose of each individual’s hands and fingers.
Carnegie Mellon University researchers have developed methods to detect the body pose, including facial expressions and hand positions, of multiple individuals.
This enables computers to not only identify parts of the body, but to understand how they are moving and positioned. This new method was developed with the help of the Panoptic Studio, a two-story dome embedded with 500 video cameras. The insights gained from experiments in that facility now make it possible to detect the pose of a group of people using a single camera and a laptop computer.
Yaser Sheikh, associate professor of robotics, said these methods for tracking 2-D human form and motion open up new ways for people and machines to interact with each other, and for people to use machines to better understand the world around them. The ability to recognize hand poses, for instance, will make it possible for people to interact with computers in new and more natural ways, such as communicating with computers simply by pointing at things.
Detecting the nuances of nonverbal communication between individuals will allow robots to serve in social spaces, allowing robots to perceive what people around them are doing, what moods they are in and whether they can be interrupted. A self-driving car could get an early warning that a pedestrian is about to step into the street by monitoring body language. In sports analytics, real-time pose detection will make it possible for computers not only to track the position of each player on the field of play, as is now the case, but to also know what players are doing with their arms, legs and heads at each point in time. The methods can be used for live events or applied to existing videos.
“The Panoptic Studio supercharges our research”, Sheikh said. It now is being used to improve body, face and hand detectors by jointly training them. Also, as work progresses to move from the 2-D models of humans to 3-D models, the facility’s ability to automatically generate annotated images will be crucial.
When the Panoptic Studio was built a decade ago with support from the National Science Foundation, it was not clear what impact it would have, Sheikh said.
“Now, we’re able to break through a number of technical barriers primarily as a result of a grant 10 years ago”, he added. “We’re sharing the code, but we’re also sharing all the data captured in the Panoptic Studio”.
