Hot-dry extremes could hit 28% of humanity five times more often by end of century
In their current state, climate policies around the world could leave a significant chunk of the global population exposed to simultaneous extreme heat and drought over five times more often by the end of this century than during the mid-to-late 20th century.

"Disordered counterpublics simulate VDA but invert its meaning. 'Verification’ becomes selective sourcing. 'Deliberation' becomes a loyalty test. 'Accountability’ means naming enemies. They look democratic on the surface but accelerate collapse.”
So much of this applies to so many spheres right now, but I see a lot of what I quoted in nominally leftist spaces.

Abstract: Low-altitude wireless networks (LAWN) require drones to follow specific trajectories controlled by ground base stations (GBSs). However, given complex low-altitude channel conditions and limited spectrum and power resources, sensing errors and wireless link unreliability cannot be ignored, leading to trajectory deviations that threaten flight safety. To address this issue, this paper proposes an integrated sensing-communication-control (ISCC) closed-loop trajectory tracking approach, aiming to reveal the coupling mechanisms among communication, sensing, and control during drone flight. In detail, we incorporate sensing errors in trajectory state estimation, packet losses in control command transmission, and finite blocklength transmission effects into the closed-loop dynamics. First, through theoretical analysis, we identify the dominant role of the time-frequency resources allocated to control in ensuring system stability and derive a lower bound on the resources required to guarantee stable operation. Second, to minimize tracking error, we formulate a time-frequency resource allocation optimization problem for the sensing, communication, and control components, subject to constraints on communication rate and closed-loop stability. Accordingly, a solution algorithm based on successive convex approximation is proposed. Third, simulation results indicate that once stability is ensured, system performance is primarily determined by sensing accuracy, with the trajectory tracking error exhibiting an approximately linear dependence on the position error bound. Finally, it is shown that the proposed ISCC scheme avoids trajectory divergence under FBL transmission compared with ISCC designs ignoring control packet loss, and could achieve decimeter-level average tracking accuracy, reducing the error to only 17.37% of that observed in the baseline global navigation satellite system scheme.

These sad and self-defeating policies in the US and Canada make our countries weaker, poorer, and stagnant.

Women's mobility networks enable more efficient travel
Our understanding of gender differences in mobility is marked by a clear tension: surveys portray women's movements as more complex than men's, while digital traces suggest less diverse travel. Here, we resolve the contradiction by modeling trajectories as networks of sequential visits, using smartphone traces linked to self-reported gender for 543,155 individuals across 10 countries. We show that the apparent conflict in the literature arises because women's mobility networks are simultaneousl…

'tear Gas Tuesday' In Downtown Portland
Over the summer of 2020, Portland's police force deployed large amounts of tear gas to suppress local demonstrations against racialised police violence. Focusing on a single representative day—2 June 2020—we simulated the path of the toxic tear gas clouds as they spread widely across the city centre, demonstrating that the concentration levels were in serious excess of recognised safe thresholds.

skinnylatte@hachyderm.io - So many people here are like, oh I wish I could move to (another country, that is also having a hard far right turn, and anti-immigrant horrors, just in a language they don’t speak)
It’s totally fine to feel you need to get away for safety and yes white cis Americans will likely face less of a threat in many places
However
I’m so irritated by the pretense that all of the current problems in the world are limited to US borders. We are going through a rough time of it.. but a lot of these problems are structurally global. ‘America is the worst’ is also a form of American exceptionalism.
