UCLA police, who were called on to handle some of the nation's largest campus protests over the Israel-Hamas war last spring, are asking for approval to double their stockpile of pepper balls and sponge rounds, obtain eight more projectile launchers and purchase three new drones. The University of California Board of Regents will consider the requests by UCLA, along with the other nine UC campus police departments, on Thursday. All California law enforcement agencies are required by state law to report annually on the acquisition and use of weapons characterized as "military equipment." A UC spokesman called the police requests a "routine agenda item" not tied to protests or other particular incidents. "All of the campus's requests are for non-lethal alternatives to standard-issue firearms, enabling officers to de-escalate situations and respond without the use of deadly force," UC spokesman Stett Holbrook said in a statement.

Machine learning methods are progressively gaining acceptance in the electron microscopy community for de-noising, semantic segmentation, and dimensionality reduction of data post-acquisition. The introduction of the APIs by major instrument manufacturers now allows the deployment of ML workflows in microscopes, not only for data analytics but also for real-time decision-making and feedback for microscope operation. However, the number of use cases for real-time ML remains remarkably small. Here, we discuss some considerations in designing ML-based active experiments and pose that the likely strategy for the next several years will be human-in-the-loop automated experiments (hAE). In this paradigm, the ML learning agent directly controls beam position and image and spectroscopy acquisition functions, and human operator monitors experiment progression in real-and feature space of the system and tunes the policies of the ML agent to steer the experiment towards specific objectives. One of the hallmarks of the meeting was the large number of presentations on machine learning (ML) in microscopy, ranging from denoising, unsupervised data analysis via variational autoencoders, and supervised learning applications for semantic segmentations and feature identification. Remarkably, by now most manufacturers offer or have plans to offer Python application programming interfaces (APIs), allowing the deployment of the codes on operational microscopes. From this perspective, the technical barriers for the broad implementation of automated microscopy in which ML algorithms analyze the data streaming from instrument detectors and make decisions based on this data are lower than ever.

Artificial intelligence, or machine learning, can increase the speed and accuracy of modeling for interconnection studies for large-scale renewables projects, said Xing Wang, global leader for grid modernization for Amazon Web Services (AWS) Energy and Utilities, in a panel discussion convened by the trade group ACORE. One type of interconnection study uses a model to evaluate how a new solar generating system will affect power flow on the grid. The model predicts power flow "but it doesn't solve," Wang said, meaning it doesn't provide a solution. "You need to find out where the issues are, and that requires years of engineering experience. We have a limited number of people who know how to do that."

The jury at Kyle Rittenhouse's murder trial Tuesday watched drone video that showed Rittenhouse wheeling around and shooting Joseph Rosenbaum at close range during a night of turbulent protests on the streets of Kenosha. The video, zoomed in and slowed down by a forensic imaging specialist, was played as the prosecution's case appeared to be winding down after a week of testimony in which some of its own witnesses often bolstered Rittenhouse's claim of self-defense. The footage showed Rosenbaum following Rittenhouse before Rittenhouse suddenly spins around and fires his rifle at him. Rosenbaum falls, and Rittenhouse runs around a car. Dr. Doug Kelley, a forensic pathologist with the Milwaukee County medical examiner's office, said Rosenbaum was shot by someone who was within 4 feet of him.

Video games have always been a source of solace in tough times for Rosemary Kelley. Now, as everything across the U.S. is being shut down and slowed down, the 25-year-old has her game controller in hand again. "I originally had every single weekend booked, and now I have nothing," she said. For Kelley, an esports caster and host for games like "Pokémon," "Overwatch" and "Hearthstone," the worsening coronavirus pandemic has led to a halt in bookings and an array of cancellations for events. The Game Developer's Conference, known as GDC, supposed to happen in March is now postponed to the summer.

Can an organisation responsibly entrust their most sensitive data and workloads to a cloud service provider without losing visibility and control? Must you risk trading security for convenience in a hybrid and multi-cloud environment? These are the kind of questions that will crop up in mind when moving your assets to the flexibility and decentralised nature of a cloud environment. As organisations move to the cloud, Diana Kelley, Microsoft's Cyber Security Field CTO, told TechRadar Middle East, that they [organisations] don't have the same kind of visibility they had on-premises but that does not mean they don't have visibility. Microsoft has two data centres in the UAE – one in Abu Dhabi and one in Dubai.

However, it is notoriously di fficult to solve in practice, because IPMs memory requirements scale at a demanding rate. Indeed, state-of-the-art SDO solvers such as MOSEK cannot solve constrained instances of Problem (1) with n 250 variables on a standard laptop, and it is optimization folklore that there is a gap between SDOs theoretical and practical tractability. Motivated by the demanding memory requirements of IPMs, a stream of literature studies inexact methods for SDOs, which replace the semidefinite constraint with weaker yet less computationally demanding constraints. This approach was first investigated by Kim and Kojima [13], who observed that relaxing a positive semidefinite constraint to the weaker constraint that all 2 2 minors of a matrix are positive semidefinite yields a second order cone (SOC)-representable outer approximation of the positive semidefinite (PSD) cone. In a related line of work, Krishnan and Mitchell [15] propose applying Kelley [12]'s cutting plane method to generate

Facebook announced on Thursday it is rolling out its newest service across the US, a platform for dating. A lot, it turns out. The new service, Facebook Dating, can be accessed in the Facebook app but requires users to create a separate dating-specific profile. It then links users with potential matches based on location, indicated preferences, events attended, groups, and other factors. Facebook Dating will integrate with Instagram and offer a feature called Secret Crush, which allows users to compile a list of friends they have an interest in, to be matched with if the crush lists them as well.
