”A more challenging area for submarines to operate undetected is the East China Sea, which is quite shallow from the Chinese coastline up to the Okinawa Trough with a depth of only 30 to 60 fathoms [180 to 360 feet] in most places,” said associate professor Peter Dutton with the China Maritime Studies Institute at the US Naval War College.
”Much of the water space [in the South China Sea] is more than 2,000 fathoms deep,”・・・.
Detecting submarines via satellite is a form of Non-Acoustic Anti-Submarine Warfare (NAASW). Lasers, infrared and other detectors and synthetic aperture radar (SAR)（合成開口レーダー） in space may be used as part of this NAASW activity. Satellites might see subtle undersea disturbances caused by submarines, watch wave patterns on or beneath the sea surface, or detect subtle variations in ocean temperature. ・・・

The US Navy later admitted that the mission had successfully detected the undersea or internal waves generated by a submarine which had been tracked successfully at relatively shallow depths. This was deemed, “incredibly important to us” and was reported by the Washington Post in 1985・・・.

・・・certain satellites can track submarine wakes, but are unable to do so continuously nor all the time, and not in all underwater environments. A submarine’s depth, and speed along with the characteristics of the ocean bottom and water clarity, among other things, come into play here. ・・・
・・・the PLAN（人民解放軍海軍）’s nuclear submarines are relatively easy to find. It is the diesel/electric submarines – and those equipped with so-called air-independent propulsion systems in particular – that are much harder to detect. ・・・
Japan has launched many advanced remote sensing/earth observation, meteorological, and engineering test satellites – exactly the types of satellites which are ideally suited for conducting satellite-based NAASW research and development. One relevant joint NASA-Japan Aerospace Exploration Agency project on the International Space Station recently tested a maritime hyperspectral imager. This coincided with work on the same type of imager done as part of the US Navy’s Tactical Space Innovative Naval Prototype program involving so-called TacSats and their maritime satellite links to buoys and “unattended” sensors – perhaps UUV-mounted sensors. ・・・

・・・the academic achievement of high school students and found that being surrounded by underachieving classmates has a negative effect on girls and boys?both genders feel pressure to conform to the lower standards of their peers. But the studies also show that girls are more sensitive than boys to the presence of high-achieving peers. Surround a girl with diligent classmates, and her performance will improve.・・・
Kirabo Jackson suggests that boys’ negative response to a strong peer group may be due to the male sex’s inherent competitiveness?boys who want to be the alpha math student may opt out of the competition if Einstein is sitting at the adjacent desk and focus instead on being the best at football or beer drinking. ・・・
・・・It was understood that oxytocin release in the context of social bonding usually required physical contact. But it’s clear from these results that a mother’s voice can have the same effect as a hug, even if they’re not standing there.・・・
・・・oxytocin responses are stronger in females than in males. In adult women the hormone plays a role in labour, preparing for birth and breastfeeding.
There might be an evolutionary reason for other responses, experts believe. A threatened male is free to choose between “fight or flight”, but this may not be so easy for a female who is pregnant or caring for offspring. It might be that females alleviate stress by making the peace.・・・

・・・Of the $13 billion planned in the United States for high-speed rail projects, $8 billion is included in the budget for this fiscal year. Other railroad powerhouses include Bombardier of Canada, Siemens of Germany and Alstom of France, as well as General Electric and Lockheed Martin of the United States. ・・・
・・・High-speed trains were once the preserve of Japan, with its “bullet train,” and France, with its TGV. But China’s trains are the world’s fastest, its network of tracks the longest and its expansion plans the most ambitious. By 2012, just four years after it began its first high-speed passenger service, China will have more high-speed train tracks than the rest of the world combined. ・・・
”Just like our investment in the highway system in the 1950s and the rail system in the late 1800s, this will pay huge dividends for China to years to come,” said Tim Schweikert, chief executive of GE Transportation China, which signed a deal last year to invest in China’s rail expansion in exchange for using Chinese trains and technology to bid on high-speed rail projects in the United States. ・・・
