Utility Workers Eliminating Consequences of Nighttime Russian Drone Attack in Kharkiv — In Photos: https://benborges.xyz/2024/03/11/utility-workers-eliminating.html

"The #Biden administration on Wednesday finalized strict limits on certain so-called 'forever chemicals' in drinking water that will require utilities to reduce them to the lowest level they can be reliably measured. Officials say this will reduce exposure for 100 million people and help prevent thousands of illnesses, including cancers.
"The rule is the first national drinkin…

EPA sets first-ever limits on PFAS in water
The Environmental Protection Agency on Wednesday announced its first-ever limits for several common types of PFAS, the so-called "forever chemicals," in drinking water. Two types, PFOA and PFOS, will be limited to 4 parts per trillion, the lowest level that tests can reliably detect. The agency says it will reduce exposure for 100 million people and prevent thousands of illnesses, including cancer. Utilities groups, however, say the EPA is underestimating the rule's cost and overestimating its …

Utility Theory of Synthetic Data Generation
Synthetic data algorithms are widely employed in industries to generate artificial data for downstream learning tasks. While existing research primarily focuses on empirically evaluating utility of synthetic data, its theoretical understanding is largely lacking. This paper bridges the practice-theory gap by establishing relevant utility theory in a statistical learning framework. It considers two utility metrics: generalization and ranking of models trained on synthetic data. The former is def…

SoK: Can Trajectory Generation Combine Privacy and Utility?
While location trajectories represent a valuable data source for analyses and location-based services, they can reveal sensitive information, such as political and religious preferences. Differentially private publication mechanisms have been proposed to allow for analyses under rigorous privacy guarantees. However, the traditional protection schemes suffer from a limiting privacy-utility trade-off and are vulnerable to correlation and reconstruction attacks. Synthetic trajectory data generatio…

Privacy-Preserving Gaze Data Streaming in Immersive Interactive Virtual Reality: Robustness and User Experience
Eye tracking is routinely being incorporated into virtual reality (VR) systems. Prior research has shown that eye tracking data can be used for re-identification attacks. The state of our knowledge about currently existing privacy mechanisms is limited to privacy-utility trade-off curves based on data-centric metrics of utility, such as prediction error, and black-box threat models. We propose that for interactive VR applications, it is essential to consider user-centric notions of utility and …

Volt Typhoon – also known as Vanguard Panda and Insidious Taurus – is a state-supported Chinese cyber operation that has compromised thousands of internet-connected devices.
it was part of a larger effort to infiltrate western critical infrastructure, including naval ports, internet service providers, communications services and utilities.
New advisories on Volt Typhoon followed a recent announcement by US authorities that they had dismantled a bot network of hundreds of compro…

Optimal consumption and investment under relative performance criteria with Epstein-Zin utility
We consider the strategic interaction of traders in a continuous-time financial market with Epstein-Zin-type recursive intertemporal preferences and performance concerns. We derive explicitly an equilibrium for the finite player and the mean-field version of the game, based on a study of geometric backward stochastic differential equations of Bernoulli type that describe the best replies of traders. Our results show that Epstein-Zin preferences can lead to substantially different equilibrium be…
