It seems these robots could be used to spy on you from home. đ
A team of researchers demonstrated that popular robotic household vacuum cleaners can be remotely hacked to act as microphones.
The researchersâincluding Nirupam Roy, an assistant professor in the University of Marylandâs Department of Computer Scienceâcollected information from the laser-based navigation system in a popular vacuum robot and applied signal processing and deep learning techniques to recover speech and identify television programs playing in the same room as the device.
The research demonstrates the potential for any device that uses light detection and ranging (Lidar) technology to be manipulated for collecting sound, despite not having a microphone. This work, which is a collaboration with assistant professor Jun Han at the University of Singapore was presented at the Association for Computing Machineryâs Conference on Embedded Networked Sensor Systems (SenSys 2020) on November 18, 2020.
Summary: Astrocytes are involved in regulating inhibitory synapses by binding to neurons through the NrCAM adhesion molecule.

In the orchestra of the brain, the firing of each neuron is controlled by two notesâexcitatory and inhibitoryâ that come from two distinct forms of a cellular structure called synapses. Synapses are essentially the connections between neurons, transmitting information from one cell to the other. The synaptic harmonies come together to create the most exquisite musicâat least most of the time.
New device puts music in your head â no headphones requiredâŠ
LONDON (AP) â Imagine a world where you move around in your own personal sound bubble. You listen to your favorite tunes, play loud computer games, watch a movie or get navigation directions in your car â all without disturbing those around you.
Thatâs the possibility presented by âsound beaming,â a new futuristic audio technology from Noveto Systems, an Israeli company. On Friday it will debut a desktop device that beams sound directly to a listener without the need for headphones.
The company provided The Associated Press with an exclusive demo of the desktop prototype of its SoundBeamer 1.0 before its launch Friday.
A biotech startup from Spain is making batteries that can power lights, music, and screens by using electrcity generated from soil microbes.
Transformer model, a deep learning framework, has achieved state-of-the-art results across diverse domains, including natural language, conversation, images, and even music. The core block of any Transformer architecture is the attention module, which computes similarity scores for all pairs of positions in an input sequence. Since it requires quadratic computation time and quadratic memory size of the storing matrix, with the increase in the input sequenceâs length, its efficiency decreases.
Thus, for long-range attention, one of the most common methods is sparse attention. It reduces the complexity by computing selective similarity scores from the sequence, based on various methods. There are still certain limitations like unavailability of efficient sparse-matrix multiplication operations on all accelerators, lack of theoretical guarantees, insufficiency to address the full range of problems, etc.
