How To Recycle HDPE Plastic (High Density Polyethylene) - a simple method. Bodycard 0236. A Neuroscientist's Radical Theory of How Networks Become Conscious - Wired Science. It’s a question that’s perplexed philosophers for centuries and scientists for decades: Where does consciousness come from?

A Neuroscientist's Radical Theory of How Networks Become Conscious - Wired Science

We know it exists, at least in ourselves. But how it arises from chemistry and electricity in our brains is an unsolved mystery. Neuroscientist Christof Koch, chief scientific officer at the Allen Institute for Brain Science, thinks he might know the answer. According to Koch, consciousness arises within any sufficiently complex, information-processing system. Internet bonding - Uplink Bonding. Acceleration - The optional Internet bonding service (Broadband Bonding Service) enables uplink bonding, therefore with BBS all traffic is aggregated for faster transfer via the Broadband Bonding(TM) technology.

Internet bonding - Uplink Bonding

Even in cases of single session, all Internet access lines are simultaneously combined together to provide a faster data transfer. Pictured below is a Truffle device bonding 6 Internet access modems. Improved network reliability - With the Internet bonding service, automatic failover is provided for all types of traffic, so that failure of one or more access lines will not cause failure of the aggregated access line, as long as at least one access line is still active.

Additionally, Automated Domain Name Service (ADNS) optimization is used to maximize the utility of all active access lines. This translates to both better performance and less downtime for your local network. Please see the features of Truffle Lite, Truffle or Portabella for additional features. Minds.

Physicists To Test If Universe Is A Computer Simulation

A philosophical thought experiment has long held that it is more likely than not that we're living inside a machine. The theory basically goes that any civilisation which could evolve to a 'post-human' stage would almost certainly learn to run simulations on the scale of a universe. And that given the size of reality - billions of worlds, around billions of suns - it is fairly likely that if this is possible, it has already happened.

Physicists Use Cloud of Rubidium Atoms as Optical Memory Device

The NIST/JQI team shows the NIST logo they stored within a vapor of rubidium atoms and three different portions of it that they were able to extract at will. Animation combines three actual images from the vapor extracted at different times. In a newly published study, researchers detail how they used a cloud of rubidium atoms as an optical memory device, showing that portions of an image written into a gradient echo memory can be individually retrieved or erased on demand, an important step toward processing a spatially multiplexed quantum signal. Talk about storing data in the cloud.

Scientists at the Joint Quantum Institute (JQI) of the National Institute of Standards and Technology (NIST) and the University of Maryland have taken this to a whole new level by demonstrating that they can store visual images within quite an ethereal memory device—a thin vapor of rubidium atoms. Publication: J.B. Lego Antikythera Mechanism. Controlling the Spin Polarization of Electrons in Three Dimensions. The interior bulk of a topological insulator is indeed an insulator, but electrons (spheres) move swiftly on the surface as if through a metal.

Controlling the Spin Polarization of Electrons in Three Dimensions

They are spin-polarized, however, with their momenta (directional ribbons) and spins (arrows) locked together. Berkeley Lab researchers have discovered that the spin polarization of photoelectrons (arrowed sphere at upper right) emitted when the material is struck with high-energy photons (blue-green waves from left) is completely determined by the polarization of this incident light. (Image Chris Jozwiak, Zina Deretsky, and Berkeley Lab Creative Services Office) Scientists from the Berkeley Lab discovered that when topological insulators are hit with a laser beam, the spin polarization of the electrons they emit can be completely controlled in three dimensions.

Observing Atomic Collapse Resonances in Artificial Nuclei on Graphene. Relativistic quantum mechanics predicts that when the charge of a superheavy atomic nucleus surpasses a certain threshold, the resulting strong Coulomb field causes an unusual atomic collapse state; this state exhibits an electron wave function component that falls toward the nucleus, as well as a positron component that escapes to infinity.

Observing Atomic Collapse Resonances in Artificial Nuclei on Graphene

In graphene, where charge carriers behave as massless relativistic particles, it has been predicted that highly charged impurities should exhibit resonances corresponding to these atomic collapse states. We have observed the formation of such resonances around artificial nuclei (clusters of charged calcium dimers) fabricated on gated graphene devices via atomic manipulation with a scanning tunneling microscope.

Setting an Application's Entry Point (The Java™ Tutorials > Deployment > Packaging Programs in JAR Files) If you have an application bundled in a JAR file, you need some way to indicate which class within the JAR file is your application's entry point. You provide this information with the Main-Class header in the manifest, which has the general form: The value classname is the name of the class that is your application's entry point.

Recall that the entry point is a class having a method with signature public static void main(String[] args). After you have set the Main-Class header in the manifest, you then run the JAR file using the following form of the java command: The main method of the class specified in the Main-Class header is executed. An Example We want to execute the main method in the class MyClass in the package MyPackage when we run the JAR file. Learn You a Haskell for Great Good! - Chapters.

Mixins encourage code reuse and avoid well-known pathologies associated with multiple inheritance.[1] Combinatorics. Informatics (academic field) Informatics is - in a general sense - the science of information. As an academic field it involves the practice of information processing, and the engineering of information systems.

It studies the structure, algorithms, behaviour, and interactions of natural and artificial systems which store, process, access, and communicate information. The field considers the interaction between humans and information systems alongside the construction of computer interfaces. Currying. Lambda calculus.
