With Cloud Computing, the Mathematics of Evolution May Get Easier to Learn

An innovative, educational computing platform developed by University at Buffalo faculty members and hosted by the cloud (remote, high-capacity, scalable servers) is helping UB students understand parts of evolutionary biology on an entirely new level. Soon, high-school and middle-school students will benefit from the same tool as well.

Pop! World, developed by UB faculty members with a $250,000 National Science Foundation grant, takes advantage of cloud computing, which allows programs to run on remote servers instead of through departmental or institutional servers. That feature allows resource-intensive programs to serve many users regardless of their physical location without sacrificing speed or quality of service.
"The cloud serves as a way to distribute resources for free without limits on how many people can access it and with no regard to what kind of computer you are downloading to," says Jessica Poulin, PhD, research assistant professor in the Department of Biological Sciences in the College of Arts and Sciences, who developed Pop! World with principal investigator Bina Ramamurthy, PhD, research associate professor in the Department of Computer Science and Engineering in the School of Engineering and Applied Sciences, and Katharina Dittmar, PhD, assistant professor of biological sciences. "Everybody can get there."
UB faculty members designed Pop! World because they wanted to get college students more excited about population genetics; they also wanted to maintain the university's unique freshman lab requirements at a time when resources are growing more scarce.
UB is one of the few universities in the U.S. that encourages freshmen interested in biology to begin experiencing labs during their first semester on campus.
"We put our freshmen right into labs because students who might otherwise be lost from the major are captivated when they get to do science," Poulin says. "When you sit in a lecture hall with 400 people and someone is talking about flatworms, what do you care? Despite the logistical difficulties, and the intense demands on staff time, we think that getting freshmen into labs is one of our department's great strengths. We didn't want to discontinue it."
At the same time, Poulin says that it is difficult to convey the main concepts of population genetics at this level, particularly those that are mathematically demanding.
Hired in 2008 to revamp UB's evolutionary biology curriculum for Bio 200, Poulin says that the department was seeking ways to maintain and improve the course and the lab for students without requiring additional resources, such as teaching assistants.
"Almost all of evolutionary theory can be mathematically modeled if you know enough information to begin with," she says. "If you enter the correct parameters into the computer, the computer will tell you what will happen after one generation or a thousand generations. I wanted students to be exposed to something that made them feel they were actually watching evolution happen. I wanted it to be captivating."
While some computational tools exist to help students with population genetics -- the mathematical analysis of evolution -- the result is often nothing more dramatic than a line graph.
"Our students grew up in the Internet age surrounded by MP3 players, wireless phones and social networking apps," says Ramamurthy, "so the visual aspects of Pop! World are certainly very appealing to them."
The UB team programmed Pop! World in Adobe Flash, which lends a highly visual, nearly tactile look to the program. While the current version illustrates evolution with red and green lizards, it is highly adaptable, so it can be used with any population of organisms. It also is highly scalable, so that it can be made more complex, to serve the needs of population genetics researchers, or less complex, to serve the needs of middle- and high-school students.
A preliminary version of Pop! World is running on the Google App Engine Cloud. It can be accessed by going to

http://popworld15.appspot.com/.

With the help of the NSF grant, the UB team is now creating a sophisticated version of the tool, expected to be available by Fall 2011.
"Our idea was to use general principles of population genetics not only to convey the principle in the context of evolutionary biology but to make sure that students understand visually what's happening with the mathematics behind it," explains Dittmar.
When an early version of Pop! World was used to teach evolutionary biology last summer, students and teaching assistants responded enthusiastically.
"The TAs loved it because it facilitated their explanations of a very complicated problem," Poulin says.
"Pop! World gives students the visual background they need to understand complex mathematical problems," Dittmar adds. "And it works kind of like a video game, which serves the current population of undergrads well."
That visual appeal is also expected to go far with middle-school and high-school biology students, groups the UB team hopes to excite about evolution; by spring, they expect to have completed a modified version for them as well.
By making evolutionary biology more visually appealing and, thus, more accessible, Poulin hopes that Pop! World will make evolution itself a more appealing subject for secondary schools to teach.
"There's a huge disconnect," she says. "The universities all accept evolution as fact. It's not a question. But many high schools and middle schools don't want to touch it. They don't want to deal with the politics of it."
Her hope is that the visual and educational appeal of Pop! World and the ease of using it will begin to change that situation.
The UB team's grant, "A Cloud-enabled Evolutionary Genetics Learning Tool for Engaging the Cyber-savvy Generation" (NSF OCI CI-Team 1041280) from the NSF's Office of Cyberinfrastructure, will run for two years.
Hongsik Kim, Jungeun Lee and Byunghun Jang, all former UB graduate students in the Department of Computer Science and Engineering, also were involved in the project.

GRIN Plasmonics: A Practical Path to Superfast Computing, Ultrapowerful Optical Microscopy and Invisibility Carpet-Cloaking Devices

ScienceDaily said it could be done and now they've done it. What's more, they did it with a GRIN. A team of researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Berkeley, have carried out the first experimental demonstration of GRIN -- for gradient index -- plasmonics, a hybrid technology that opens the door to a wide range of exotic optics, including superfast computers based on light rather than electronic signals, ultra-powerful optical microscopes able to resolve DNA molecules with visible light, and "invisibility" carpet-cloaking devices.

Working with composites featuring a dielectric (non-conducting) material on a metal substrate, and "grey-scale" electron beam lithography, a standard method in the computer chip industry for patterning 3-D surface topographies, the researchers have fabricated highly efficient plasmonic versions of Luneburg and Eaton lenses. A Luneburg lens focuses light from all directions equally well, and an Eaton lens bends light 90 degrees from all incoming directions.
"This past year, we used computer simulations to demonstrate that with only moderate modifications of an isotropic dielectric material in a dielectric-metal composite, it would be possible to achieve practical transformation optics results," says Xiang Zhang, who led this research. "Our GRIN plasmonics technique provides a practical way for routing light at very small scales and producing efficient functional plasmonic devices."
Zhang, a principal investigator with Berkeley Lab's Materials Sciences Division and director of UC Berkeley's Nano-scale Science and Engineering Center (SINAM), is the corresponding author of a paper in the journal Nature Nanotechnology, describing this work titled, "Plasmonic Luneburg and Eaton Lenses." Co-authoring the paper were Thomas Zentgraf, Yongmin Liu, Maiken Mikkelsen and Jason Valentine.
GRIN plasmonics combines methodologies from transformation optics and plasmonics, two rising new fields of science that could revolutionize what we are able to do with light. In transformation optics, the physical space through which light travels is warped to control the light's trajectory, similar to the way in which outer space is warped by a massive object under Einstein's relativity theory. In plasmonics, light is confined in dimensions smaller than the wavelength of photons in free space, making it possible to match the different length-scales associated with photonics and electronics in a single nanoscale device.
"Applying transformation optics to plasmonics allows for precise control of strongly confined light waves in the context of two-dimensional optics," Zhang says. "Our technique is analogous to the well-known GRIN optics technique, whereas previous plasmonic techniques were realized by discrete structuring of the metal surface in a metal-dielectric composite."
Like all plasmonic technologies, GRIN plasmonics starts with an electronic surface wave that rolls through the conduction electrons on a metal. Just as the energy in a wave of light is carried in a quantized particle-like unit called a photon, so, too, is plasmonic energy carried in a quasi-particle called a plasmon. Plasmons will interact with photons at the interface of a metal and dielectric to form yet another quasi-particle, a surface plasmon polariton (SPP).
The Luneburg and Eaton lenses fabricated by Zhang and his co-authors interacted with SPPs rather than photons. To make these lenses, the researchers worked with a thin dielectric film (a thermplastic called PMMA) on top of a gold surface. When applying grey-scale electron beam lithography, the researchers exposed the dielectric film to an electron beam that was varied in dosage (charge per unit area) as it moved across the film's surface. This resulted in highly controlled differences in film thickness across the length of the dielectric that altered the local propagation of SPPs. In turn, the "mode index," which determines how fast the SPPs will propagate, is altered so that the direction of the SPPs can be influenced.
"By adiabatically tailoring the topology of the dielectric layer adjacent to the metal surface, we're able to continuously modify the mode index of SPPs," says Zentgraf. "As a result, we can manipulate the flow of SPPs with a greater degree of freedom in the context of two-dimensional optics."
Says Liu, "The practicality of working only with the purely dielectric material to transform SPPs is a big selling point for GRIN plasmonics. Controlling the physical properties of metals on the nanometer length-scale, which is the penetration depth of electromagnetic waves associated with SPPs extending below the metal surfaces, is beyond the reach of existing nanofabrication techniques."
Adds Zentgraf, "Our approach has the potential to achieve low-loss functional plasmonic elements with a standard fabrication technology that is fully compatible with active plasmonics."
In the Nature Nanotechnology paper, the researchers say that inefficiencies in plasmonic devices due to SPPs lost through scattering could be reduced even further by incorporating various SPP gain materials, such as fluorescent dye molecules, directly into the dielectric. This, they say, would lead to an increased propagation distance that is highly desired for optical and plasmonic devices. It should also enable the realization of two-dimensional plasmonic elements beyond the Luneburg and Eaton lenses.
Says Mikkelsen, "GRIN plasmonics can be immediately applied to the design and production of various plasmonic elements, such as waveguides and beam splitters, to improve the performance of integrated plasmonics. Currently we are working on more complex, transformational plasmonic devices, such as plasmonic collimators, single plasmonic elements with multiple functions, and plasmonic lenses with enhanced performance."
This research was supported by the U.S. Army Research Office and the National Science Foundation's Nano-scale Science and Engineering Center.

Internet Cyclone is compatible with all modems and high speed LAN, ISDN, CABLE, DSL, T1 or other connections. This software will still be useful to you after upgrading your Internet connection.

Using this software you will gain guaranteed faster Internet speed for the time you're online. Surfing, downloading files, emailing, playing online games, and anything else you do online will be faster. This is excellent software for slow dial-up modems as well as high speed access connections.


This software will be extremely valuable to you as you continue to upgrade your computer and connections. It will work with all connections and all browsers so it will still be extremely useful to you in the future. You should use Internet Cyclone as a REAL alternative to expensive upgrades.


What can Internet Cyclone offers to you ?
- Internet Cyclone optimizes your Windows settings automatically or you can customize them.
- You can speed internet connection without changing your Hardware.
- Works with all Browsers.
- It is compatible with all Dial-Up modems and high speed LAN, CABLE, DSL, DSL (PPPoE), T1 or other connections.
- Internet Cyclone will speed up web surfing, online gaming, e-mailing, chat and video conference and it will even speed up downloads
.

How does this work ?
While the actual maximum transfer speed of your Internet connection cannot be changed except by upgrading your hardware, Internet Cyclone can increase the performance of your existing modem/network hardware by optimizing Windows modem/network settings to maximize the efficiency of your current hardware. By default, your Windows PC does not manage Internet connections as optimally as possible.

Internet Cyclone is designed to automatically change many registry settings in Windows such as: Maximum Transmission Unit (MTU), Maximum Segment Size (MSS), Time To Live (TTL), TCP Receive Window (Rwin), Cache Size (NDI), PMTU Black Hole Detect, PMTU Auto Discovery (PAD), Session Keep Alive (SKA) and some Windows Extra settings like: Selective Acknowledgement (SACK), Maximum Duplicate Acknowledge (Max DupAcks), Large Window Scaling, Ports COM, VCache value, Combuffer value, Internet Explorer settings, Maximum connection per server.

If these settings are not correctly optimized then you will not get the best performance of your Internet Connection. Internet Cyclone is a proof method to change these settings easily and quickly. If you are an experienced user, then with this Internet optimizer you can set these values manually and speed up Internet connection at maximum.

How much speed can you gain with Internet Cyclone ?
It will not make your 56k dial-up modem connection to 100k. If your Internet connection speed is a 56k dial-up modem , it will provides you to use it with the best performance. For example we were informed by other people that this Internet optimizer helped them to boost their high speed Internet connections up to 120kb/s (this means a boost of 400%). Microsoft publishes Windows operating systems with default settings (the most compatible settings with all systems). But you cannot get the best performance of your Internet connection with this default values. At that moment, you need Internet Cyclone to change this Windows Registry settings that affects Internet connection speed through a simple, intuitive interface, and by giving you the chance to speed internet connection.

In the UNREGISTERED version of Internet Cyclone there are disabled the extra settings in Windows registry such as: SlowNet Option, SACK Option, Max DupAcks, Large Window Scaling, Maxim Connection per Server, VCache value, Combuffer value, the speed of Com ports, Maximum Sockets Value and Maximum Connection Value, settings that will improve even more your Internet connection speed.

System Requirements:

- 486DX2/66 required, Pentium class or higher recommended
- Microsoft(r) Windows(r) NT, 2000, 2003, XP, Me, 98, 95
- 16Mb of Memory or Higher
- Any connection to the net.
- 2 MB of free disk space
