Dew helps ground cloud computing


2015-09-15
(Press-News.org) The most obvious disadvantage of putting your data in the cloud is losing access when you have no internet connection. According to research publishes in the International Journal of Cloud Computing, this is where "dew" could help. Yingwei Wang of the Department of Computer Science, at the University of Prince Edward Island, Charlottetown, Canada, describes what he refers to as a "cloud-dew" architecture that offers an efficient and elegant way to counteract cloud downtime and communication difficulties.

In the world of cloud computing, users and organizations keep their data in the cloud, users access the data from their computer, which means their data is mobile and can be accessed from any computer...but only as long as an internet connection is available. The problem with this arrangement is that the user relies heavily on an internet connection and the cloud servers, Wang explains. "If any problem happens with the servers or an internet connection is not available, the user cannot access their data," he says.

When a user has lots of complex data, the task of keeping it in sync manually between the cloud and local computers is anything but trivial. Wang's architecture follows the conventions of cloud architecture but in addition to the cloud servers, there are dew servers held on the local system that act as a buffer between the local user and the cloud servers and avoid the problem of data becoming out of sync, which happens if one simply reverts to the old-school approach in which data is held only on the local server whether or not it is networked. "The dew server and its related databases have two functions: first, it provides the client with the same services as the cloud server provides; second, it synchronizes dew server databases with cloud server databases," explains Wang.

The dew server is a lightweight local server that retains a copy only of the given user's data making it available with or without an internet connecting and syncing once more with the cloud server as soon as a connection is available once more. The same cloud-dew architecture might also be used to make websites available offline. Such a system could reduce the internet data overheads for an organization that has intermittent or throttled internet connectivity. Obviously form filling or email exchange is not possible without the internet connection but many functions such as displaying files and images, playing audio or video would be possible provided the data had been synced to the "dewsite" from the web during the last connection period.

Sweeping study of US farm data shows loss of crop diversity the past 34 years

2015-09-15
MANHATTAN, KANSAS - U.S. farmers are growing fewer types of crops than they were 34 years ago, which could have implications for how farms fare as changes to the climate evolve, according to a large-scale study by Kansas State University, North Dakota State University and the U.S. Department of Agriculture. Less crop diversity may also be impacting the general ecosystem. "At the national level, crop diversity declined over the period we analyzed," said Jonathan Aguilar, K-State water resources engineer and lead researcher on the study. The scientists used data from ...

In first, Salk scientists use sound waves to control brain cells

In first, Salk scientists use sound waves to control brain cells
2015-09-15
LA JOLLA--Salk scientists have developed a new way to selectively activate brain, heart, muscle and other cells using ultrasonic waves. The new technique, dubbed sonogenetics, has some similarities to the burgeoning use of light to activate cells in order to better understand the brain. This new method--which uses the same type of waves used in medical sonograms--may have advantages over the light-based approach--known as optogenetics--particularly when it comes to adapting the technology to human therapeutics. It was described September 15, 2015 in the journal Nature ...

Additional time spent outdoors by children results in decreased rate of nearsightedness

2015-09-15
The addition of a daily outdoor activity class at school for three years for children in Guangzhou, China, resulted in a reduction in the rate of myopia (nearsightedness, the ability to see close objects more clearly than distant objects), according to a study in the September 15 issue of JAMA. Myopia has reached epidemic levels in young adults in some urban areas of East and Southeast Asia. In these areas, 80 percent to 90 percent of high school graduates now have myopia. Myopia also appears to be increasing, more slowly, in populations of European and Middle Eastern ...

Sex differences in academic faculty rank, institutional support for biomedical research

2015-09-15
Women are less likely than men to be full professors at U.S. medical schools, and receive less start-up support from their institutions for biomedical research, according to two studies in the September 15 issue of JAMA. Women now make up half of all U.S. medical school graduates. However, sex disparities in senior faculty rank persist in academic medicine. Whether differences in age, experience, specialty, and research productivity between sexes explain persistent disparities in faculty rank has not been studied. Anupam B. Jena, M.D., Ph.D., of Harvard Medical School, ...

Factors for higher risk of death following hip fracture surgery than hip replacement

2015-09-15
Patients undergoing surgery for a hip fracture were older and had more medical conditions than patients who underwent an elective total hip replacement, factors that may contribute to the higher risk of in-hospital death and major postoperative complications experienced by hip fracture surgery patients, according to a study in the September 15 issue of JAMA. Although hip surgery can improve mobility and pain, it can be associated with major postoperative medical complications and mortality. Patients undergoing surgery for a hip fracture are at substantially higher risk ...

Equity gap

2015-09-15
Women physicians are substantially less likely to be full professors than men of similar age, experience, specialty and research productivity. With recent increases in the number of women attending medical school, women now comprise nearly half of all new physicians. But the proportion of women at the rank of fullprofessor at U.S. medical schools has not changed since 1980, despite efforts to increase equity, according to a new research study led by Anupam Jena, associate professor of health care policy at Harvard Medical School. The results are published today in JAMA. "Many ...

Doubt cast on recent study claiming to have unraveled the last mystery of electromagnetism

2015-09-15
A group of scientists from ITMO University, Australian National University and Aalto University called into question the results of a study, published by the researchers from Cambridge University in a prestigious scientific journal Physical Review Letters. In the original study, the British scientists claimed that they managed to find the missing link in the electromagnetic theory. The findings, according to the scientists, could help decrease the size of antennas in electronic devices manifold, promising a major breakthrough in the field of wireless communications. The ...

Popular hypertension drugs linked to worse heart health in blacks compared to whites

2015-09-15
Drugs commonly used to treat high blood pressure, and prevent heart attacks and strokes, are associated with significantly worse cardiovascular outcomes in hypertensive African Americans compared to whites, according to a new comparative effectiveness research study led by researchers in the Department of Population Health at NYU Langone Medical Center. The study, published on September 15 in the Journal of the American College of Cardiology (JACC), is unique, the authors say, in that it evaluates racial differences in cardiovascular outcomes and mortality between hypertensive ...

New perspectives for long-term climate predictions?

New perspectives for long-term climate predictions?
2015-09-15
Are climate predictions over periods of several years reliable if weather forecast are still only possible for short periods of several days? Nevertheless there are options to predict the development of key parameters on such long time scales. A new study led by scientists at GEOMAR Helmholtz Centre for Ocean Research Kiel shows how the well-known 11-year cycle of solar activity affects the long-time development of dominant large-scale pressure systems in the Northern Hemisphere. For their investigations the scientists used a coupled ocean-atmosphere model. In addition, ...

Number of people at high risk of fracture set to double by 2040

2015-09-15
September 15, 2015 - Nyon, Switzerland A study from the University of Southampton and Sheffield Medical School in the UK projects a dramatic increase in the burden of fragility fractures within the next three decades. By 2040, approximately 319 million people will be at high risk of fracture -double the numbers considered at high risk today. In this first study to estimate the global burden of disease in terms of fracture probability, the researchers quantified the number of individuals worldwide aged 50 years or more at high risk of fracture in 2010 and projected figures ...
