My name is Artem, I’m a computational neuroscience student and researcher. In this video we talk about cognitive maps – internal models of outside world that the brain to generate flexible behavior that is generalized across contexts.
MIT researchers built DiffDock, a diffusion generative model that could potentially find new drugs faster than traditional methods and reduce the potential for adverse side effects.
Threat actors used a well-liked piece of corporate communication software from 3CX, according to security experts. In particular, reports state that a desktop client for the 3CX VoIP (Voice over Internet Protocol) service was used to specifically target 3CX’s clients.
It is believed that the attack is a multi-part process, with the first stage using a hacked version of the 3CX desktop application. Although the.exe file and the MSI package have the same name, preliminary research indicates that the MSI package is the one that may include DLLs that have been maliciously modified.
Researchers from multiple security companies have reported that a massive supply chain attack on users of 3CX, a widely utilized voice and video calling desktop client, was carried out by computer hackers working on behalf of the government of North Korea. The attack targeted users of the Windows and macOS operating systems. 3CX users may make calls, examine the status of colleagues, chat, plan a video conference, and check voicemails all from the desktop program by using the 3CXDesktopApp, which is accessible for Windows, macOS, Linux, and mobile devices.
The attack resulted in the compromising of the software build system that was used to generate and distribute versions of the app for Windows and macOS. The app delivers VoIP and PBX services to “over 600,000 clients,” some of which include American Express, Mercedes-Benz, and Price Waterhouse Cooper. Since the attackers controlled the software development system, they were able to insert malware into 3CX applications, even though those applications had been digitally signed using the official signing key for the firm.
Laser-driven Hohlraums filled with gas at lower densities (0.6 mg/cc) have higher efficiency compared to original ≥ 0.96 mg/cc fill because of reduced backscatter losses [Hall et al., Phys. Plasma…
Many scientific problems can be formulated as sparse regression, i.e., regression onto a set of parameters when there is a desire or expectation that some of the parameters are exactly zero or do not substantially contribute. This includes many problems in signal and image processing, system identification, optimization, and parameter estimation methods such as Gaussian process regression. Sparsity facilitates exploring high-dimensional spaces while finding parsimonious and interpretable solutions. In the present work, we illustrate some of the important ways in which sparse regression appears in plasma physics and point out recent contributions and remaining challenges to solving these problems in this field. A brief review is provided for the optimization problem and the state-of-the-art solvers, especially for constrained and high-dimensional sparse regression.
Magneto-inertial fusion concepts, such as the magnetized liner inertial fusion (MagLIF) platform[M. R. Gomez et al., Phys. Rev. Lett. 113, 155003 (2014)], constitute an alternative path for achiev…
Researchers have attained a 100-fold increase in the accuracy of a molecular clock that could serve as a terahertz-frequency standard and as a platform for investigating new physics.
