Sep. 2, 2022 — Researchers have used computer simulations to show that stable aromatic molecules can become reactive after absorbing light. Sep. 1, 2022 — Granular matter is all around us. Examples include sand, rice, nuts, coffee and even snow. These materials are made of solid particles that are large enough not to experience thermal fluctuations. Aug. 29, 2022 — Scientists have developed a mathematical description of what happens within tiny magnets as they fluctuate between states when an electric current and magnetic field are applied. Aug. 25, 2022 — Bike-sharing is a way for cities to cut their greenhouse gas emissions while limiting urban congestion. But bikes have to be available when and where people want them. Aug. 15, 2022 — An international research team has detected novel quantum effects in high-precision studies of natural double-layer graphene. Aug. 15, 2022 — Researchers have shown that a component of modern computer processors that enables different areas of the chip to communicate with each other is susceptible to a side-channel attack. Aug. 10, 2022 — Researchers have developed a technique to 3D-print materials with customizable mechanical properties that can also sense how they are moving and interacting with their environment. Aug. 9, 2022 — Investigators have created the most bio-realistic and complex computer models of individual brain cells -- in unparalleled quantity.

Computer Space debuted at the MOA show on October 15-17, 1971. Dabney's wooden cabinet for the initial prototype was replaced with a curvy, futuristic fiberglass cabinet designed by Bushnell with modelling clay and built by a swimming pool manufacturer. A control panel extended from the main body of the cabinet and contained the four control buttons; Syzygy had hoped to use a joystick to control the rocket's movement, but found that it broke too easily, failing to last a single night in a location test. The Galaxy Game designers had run into the same issue, but had solved it with expensive customized military surplus joysticks. The cabinet displayed the Nutting Associates name and logo, along with the term "Syzygy engineered". Nutting displayed four cabinets at the MOA show, one each in red, blue, white, and yellow, with the implication that the game was already in production, though they were in fact the only four cabinets then produced.
In the novel, the orders to disconnect HAL come from Dave and Frank's superiors on Earth. After Frank is killed while attempting to repair the communications antenna he is pulled away into deep space using the safety tether which is still attached to both the pod and Frank Poole's spacesuit. Dave begins to revive his hibernating crew mates, but is foiled when HAL vents the ship's atmosphere into the vacuum of space, killing the awakening crew members and almost killing Bowman, who is only narrowly saved when he finds his way to an emergency chamber which has its own oxygen supply and a spare space suit inside. In both versions, Bowman then proceeds to shut down the machine. In the film, HAL's central core is depicted as a crawlspace full of brightly lit computer modules mounted in arrays from which they can be inserted or removed. Bowman shuts down HAL by removing modules from service one by one; as he does so, HAL's consciousness degrades. Post was creat ed with the help of GSA Content Gen erator Dem oversion!
Steady-state visual evoked potentials have been used for binary selection,48-51 both discrete and continuous control of a cursor in 2 dimensions,52 prosthesis control,53 FES,54,55 spelling,56 and environmental control.57 For patients with impaired vision, various auditory39,40,58-61 and tactile62-65 paradigms have been investigated. In addition, some researchers are exploring the use of BCIs in neurorehabilitation.68 The hypothesis is that BCIs can augment current rehabilitation therapies by reinforcing and thereby increasing more effective use of impaired brain areas and connections.69,70 Studies in stroke patients have shown that, with a motor relearning intervention, EEG features change in parallel with improvement in motor function71 and that sensorimotor rehabilitation using BCI training and motor imagery may improve motor function after CNS injury.72 It also appears that combining a BCI with FES or assistive robotics may aid motor relearning in stroke patients.73 Brain-computer interface-based therapy might provide a useful complement to standard neurorehabilitation methods and might lower cost by reducing the need for the constant presence of a rehabilitation therapist.
