When Stephen Hawking wanted to speak, he chose letters and words from a synthesiser screen controlled by twitches of a muscle in his cheek. But the painstaking process the cosmologist used might soon be bound for the dustbin. In its current form, the brain-reading software works only for stock sentences it has been trained on, but scientists believe it is a stepping stone towards a more powerful system that can decode in real time the words a person intends to say. Doctors at the University of California in San Francisco took on the challenge in the hope of creating a product that allows paralysed people to communicate more fluidly than using existing devices that pick up eye movements and muscle twitches to control a virtual keyboard. The work, funded by Facebook , was possible thanks to three epilepsy patients who were about to have neurosurgery for their condition. Before their operations went ahead, all three had a small patch of tiny electrodes placed directly on the brain for at least a week to map the origins of their seizures. He used the electrodes to record brain activity while each patient was asked nine set questions and asked to read a list of 24 potential responses. With the recordings in hand, Chang and his team built computer models that learned to match particular patterns of brain activity to the questions the patients heard and the answers they spoke.

Performance measurement of broadband simple decoding in short-range MIMO Abstract: In a short-range multiple-input and multiple-output SR-MIMO transmission system that relies on line-of-sight LOS propagation, the channel matrix is determined by the antenna geometry, hence radio frequency RF signal processing by using an analog matrix circuit is a valid means of separating spatially-multiplexed multiple signal streams.
To date several simple decoding methods utilizing this feature for SR-MIMO transmission have been proposed and demonstrated at one frequency point. This paper presents a demonstration of a simple decoding method for two-branch SR-MIMO transmission in a broadband with eight percent relative bandwidth, which corresponds to two-channel usage in the GHz band.

Join Dr. Millions of years of evolution has aided animals and insects to develop the highly sensitive ability to track and navigate odor plumes over great distances. This behavior is integral to their survival and propagation of the species; decades of research has gone into finding a way to replicate this inate behaviour in autonomous mobile robots. And while it is accepted that animals are able to find hidden information from complex signals for odor navigation purposes, the sub-Hz bandwidth of chemical sensors largely limits the efficacy of information retrieval.
Naturally, this hinders the application of mobile robots for chemical source localization tasks. During this webinar sponsored by Aurora Scientific , Dr.

While discussing a breakup story with a co-worker, I learned yet another scary lesson about women for me to add to the existing volumes of scary women lessons that grace my mental bookshelves: Women don’t always mean what they say, and they expect us guys to know when they mean something and when they don’t. Now, my co-worker Allison explained that the event that kicked off her descent into breakup was her boyfriend missing an afternoon flight to visit for Valentine’s weekend.
The boyfriend is older , and she was gradually getting fed up with his irresponsible ways. Missing this afternoon flight wasn’t the best thing for his relationship resume. Then, a defining moment: during the conversation, Allison’s boyfriend apologized for missing his flight. Allison angrily told him:. Don’t even come here. Don’t worry about getting another flight. So, he did what he was told, and didn’t visit her in NYC.
In fact, on Valentine’s Day, he went “radio silence,” as Allison put it. I guess he figured he was already in the doghouse after the blowup over the missed flight , so he thought it best to lay low.
World Energy Issues Monitor 2020: Decoding new signals of change
As the COVID pandemic continues to impact every corner of the world, pulling together as a community of deep expertise has never been more important – to share experiences and lessons learned, and better prepare for and shape what comes next. The edition of the World Energy Issues Monitor provides unique insights into what energy leaders identify as their critical uncertainties and action priorities this year.
Based on the 11th annual survey and analysis of over 3, survey responses from energy leaders in countries, the World Energy Council has identified major trends and agenda items which are relevant to new energy and energy-related developments in regionally diverse systems. We are reaching out beyond the energy sector to engage new and non-traditional energy transition leaders.
The World Energy Issues Monitor identifies the shifting patterns of connected issues that impact energy systems development and transition on a multi-local, regional and global basis. Some of the key trends and topics that have emerged from tracking these issues over time as well as the survey of individual consumers are:.
Decoding sexual intent is an arguably difficult task, particularly if the perceiver hopes individuals often disagree about the meaning of nonverbal sexual signals. images of clothed women displaying one of the four dating-relevant emotions.
Men and women often disagree about the meaning of women’s nonverbal cues, particularly those conveying dating-relevant information. Men perceive more sexual intent in women’s behavior than women perceive or report intending to convey. Although this finding has been attributed to gender differences in the threshold for labeling ambiguous cues as sexual in nature, little research has been conducted to determine etiology.
Using a model that differentiates perceptual sensitivity from decisional bias, we found no evidence that men have lenient thresholds for perceiving women’s nonverbal behavior as indicating sexual interest. Rather, gender differences were captured by a relative perceptual insensitivity among men. Just as in previous studies, men were more likely than women to misperceive friendliness as sexual interest, but they also were quite likely to misperceive sexual interest as friendliness.
The results point to the promise of computational models of perception in increasing the understanding of clinically relevant social processes.

Description: Spectral encoder, spectral decoder, acoustic signal transmitter, acoustic signal receiver, and methods thereof. The present invention relates to a method for improving sound quality by extending a frequency band of an audio signal or a voice signal, and further relates to a coding method and a decoding method for an audio signal or a voice signal to which the method is applied.
Background art. Audio coding technology and audio coding technology for compressing audio signals or audio signal at a low bit rate are important for effective use of transmission line capacity such as radio waves and recording media in mobile communication. There are G These methods target narrowband signals Hz to 3. However, such narrow-band signals have a narrow frequency band, up to 3. In the field of speech coding, there is a method for coding a wideband signal 50 Hz to 7 kHz.
As a typical method, there are 1 11 11 11 7 2 2 G 7 These methods can encode wideband audio signals at bit rates of 6. If the signal to be coded is speech, the wideband signal is of relatively high quality, It is not enough when it is used for audio signals or when high quality sound is required for audio signals. In general, the maximum frequency of the signal is 1 5 when there until about kH Z is realistic considerable FM radio obtained, 20 kH CD quality comparable if Z up to about are obtained, et al.
However, in the case of these audio coding methods, the frequency band to be coded is widened, so that the bit rate is increased. A technique is described in which the overall bit rate is reduced by substituting and replacing the spectrum in the low-frequency part.

Global Positioning System GPS satellites broadcast microwave signals to enable GPS receivers on or near the Earth’s surface to determine location and time, and to derive velocity. The system is operated by the U. Department of Defense DoD for use by both the military and the general public. GPS signals include ranging signals, used to measure the distance to the satellite, and navigation messages.
The navigation messages include ephemeris data, used to calculate the position of each satellite in orbit, and information about the time and status of the entire satellite constellation, called the almanac.
