End to end 5G for super, superfast mobile
The broadest of broadband for mobile

(Press-News.org) A collaboration between NEC Electronics Samsung and several academic centres in China and Iran, is investigating how software-defined cellular networking might be used to give smart phone users the next generation of super-superfast broadband, 5G. They provide details in the International Journal of Communication Networks and Distributed Systems.
Currently, the fourth generation of mobile phone connection technology, 4G, in as far as it has been adopted provides broadband-type connectivity for enabled devices such as smart phones, tablet computers, laptops and other gadgets through two standards: the Mobile WiMAX standard (first used in South Korea in 2007), and the first-release Long Term Evolution (LTE) standard (in Oslo, Norway and Stockholm, Sweden since 2009). Peak speeds were set in the standards at 100 megabits per second (Mbit/s) for mobile users and ten times that for static, domestic 5G users, 1 gigabit per second. 100 Mbits/s is three times faster than the earlier 3G system but users commonly do not see data transfer at such high rates, downloads are usually at best 10 Mbits/s.
As yet there is no single standard for 5G although various systems are being touted based on rebuilding the cellular networks to be super-efficient and exploiting different frequencies with their capacity for greater data rates. The hope is to be able to achieve download speeds of perhaps 10 Gbits/s.
Ming Lei of Samsung Research and Development Institute China, Lei Jiang of NEC Laboratories, both in Beijing are working with colleagues at the University of Electronic Science and Technology of China in Chengdu, Beijing Jiaotong University and the University of Kurdistan. They have assessed the latest developments aimed at 5G systems and have proposed their own novel end-to-end (E2E) software-defined cellular network (SDCN) architecture which they say offers flexibility, scalability, agility and efficiency. Moreover, it will be sustainable for providers as well as profitable.
They are currently building a demonstration system that will allow them to utilise several promising technologies in their architecture for 5G including cloud computing, network virtualisation, network functions virtualisation and dynamic service chaining. The approach, they suggest could overcome bandwidth shortage problems, improve quality of service so avoiding delays and data loss, as well as reducing the vast number of error-prone network nodes needed for such a system.

WOODS HOLE, Mass.--David Johnson was standing in a salt marsh on the northern Massachusetts coast when he saw a fiddler crab, Uca pugnax, nearly 50 miles north of its supposed natural range. The migration north of this charismatic crab with the big, waving claw may be yet another sign of climate change. Johnson, then a scientist at the Marine Biological Laboratory (MBL) Ecosystems Center, has published his observations in the Journal of Crustacean Biology.
The fiddler crab is an attention-getting crustacean; the males have an oversized claw that they use to attract a ...

Over a million US military veterans lacked healthcare coverage in 2012, according to new estimates published in The Lancet. While many people believe that all veterans are covered by the Veterans Affairs health care system, less than half (8.9 million) of the 22 million veterans in the US are covered by VA health benefits, and most veterans are covered by private health insurance. Uninsured veterans are more likely to be young, single, African American, and veterans of Iraq and Afghanistan.
However, the authors of this viewpoint estimate that universal health coverage ...

There has been a growing concern that modern society is increasingly lonely. In 2006, a New York Times article "The Lonely American Just Got a Bit Lonelier" highlighted research that shows a decline in social engagement--people are less likely to join clubs, have fewer close friends, and are less likely to perceive others as trustworthy. However, studies have also shown an increase in extraversion and self-esteem, which suggests loneliness is decreasing.
In an effort to study the societal trend of loneliness, researchers from the University of Queensland and Griffith ...

Abnormal connections between neurons are the likely cause of motor coordination issues seen in autism spectrum disorder. Using a mouse model of autism, scientists from the University of Chicago identified a malfunctioning neural circuit associated with reduced capacity for motor learning. This appears to arise from an inability to eliminate unneeded neural connections in the brain. They report their findings Nov. 24 in Nature Communications.
"We have identified synaptic abnormalities that may play a role in motor problems typically seen in children with autism," said ...

Adult survivors of retinoblastoma, a type of eye cancer that usually develops in early childhood, have few cognitive or social problems decades following their diagnosis and treatment. That's the conclusion of a study published early online in CANCER, a peer-reviewed journal of the American Cancer Society. The findings offer good news for patients, but it's important to continue to monitor for long-term effects as the brain changes throughout life.
While most children with retinoblastoma are successfully cured, little is known about the long-term health of survivors. ...

ATLANTA--Promoting healthy gut microbiota, the bacteria that live in the intestine, can help treat or prevent metabolic syndrome, a combination of risk factors that increases a person's risk for heart disease, diabetes and stroke, according to researchers at Georgia State University and Cornell University. Their findings are published in the journal Gastroenterology.
The study, a follow-up to the research team's previous paper in Science, uses an improved technical approach, making the results more significant.
The research team includes Dr. Andrew Gewirtz, a professor ...

A gene associated with schizophrenia plays a role in brain development and may help to explain the biological process of the disease, according to new Rutgers research.
In the study, published in Biological Psychiatry, Bonnie Firestein, professor in the Department of Cell Biology and Neuroscience, says too much protein expressed by the NOS1AP gene, which has been associated with schizophrenia, causes abnormalities in brain structure and faulty connections between nerve cells that prevent them from communicating properly.
Firestein's research indicates that an overabundance ...

Being in a position of power can fundamentally change the way you speak, altering basic acoustic properties of the voice, and other people are able to pick up on these vocal cues to know who is really in charge, according to new research published in Psychological Science, a journal of the Association for Psychological Science.
We tend to focus on our words when we want to come across as powerful to others, but these findings suggest that basic acoustic cues also play an important role:
"Our findings suggest that whether it's parents attempting to assert authority over ...

Babies start breathing in the womb, inhaling and exhaling irregularly at first, and then gradually more and more, until the day when they're born and have to do it all the time. But premature babies sometimes have trouble. They stop breathing periodically, sometimes for 20 or 30 seconds at a time. Sometimes they're fine, and sometimes they're not, and doctors struggle to help them. That may soon change, however, thanks to a two-month-old patient at UConn Health with a rare connexin mutation, and his doctor's willingness to call for help. The resulting collaboration between ...
