An Analytic Description of Electron Thermalization in Kilonovae Ejecta
A simple analytic description is provided of the rate of energy deposition by $β$-decay electrons in the homologously expanding radioactive plasma ejected in neutron star mergers, valid for a wide range of ejecta parameters -- initial entropy, electron fraction $\{s_0,Y_e\}$ and density $ρt^3$. The formulae are derived using detailed numerical calculations following the time-dependent composition and $β$-decay emission spectra (including the effect of delayed deposition). The deposition effi…

SUPPLY: Sustainable multi-UAV Performance-aware Placement Algorithm for Flying Networks
Unmanned Aerial Vehicles (UAVs) are used for a wide range of applications. Due to characteristics such as the ability to hover and carry cargo on-board, rotary-wing UAVs have been considered suitable platforms for carrying communications nodes, including Wi-Fi Access Points and cellular Base Stations. This gave rise to the concept of Flying Networks (FNs), now making part of the so-called Non-Terrestrial Networks (NTNs) defined in 3GPP. In scenarios where the deployment of terrestrial networks …

A good editorial re Uber and Lyft threatening to leave Minneapolis if they have to actually pay their drivers more than dirt:

Uber and Lyft are the corporations that cry wolf • Minnesota Reformer
When legislators pass laws that treat them like all other businesses, Uber and Lyft whip out a well-worn corporate playbook: claim the sky is falling by misrepresenting policy proposals or exaggerating their potential impact, and threatening to leave unless policymakers back off.

Drift-Energy Replacement Effect in Multi-Ion Magnetized Plasmas
Fast rotation can improve the stability and confinement of fusion plasmas. However, to maintain a rapidly rotating fusion plasma in steady state, significant energy must be invested in spinning up each incoming fuel ion. We show here that, under the right circumstances, collisional cross-field radial fueling can directly transfer drift energy between outgoing and incoming ions without the need for external power recirculation, thereby reducing the energy costs of maintaining the rotation.

Minneapolis officers reprimanded for misconduct in 2020 after George Floyd’s murder
Newly published discipline reports reveal that former police chiefs moved to terminate two officers for excessive force and suspended others for failing to uphold department policy.

🧵 Thread: Re-plugging an old article that my friend, mentee and former colleague Mythri Prabhakara wrote about learning digital security over approximately 8 months while navigating her #neurodivergence and other intersectional identities, and a pandemic to boot.
(I’ve shared an archived link because the footnotes and text currently displaying are a bit weird.)

Learning digital security as a “non-techie”
A wooden duster came flying at 11-year-old me. I had misspelled my Venn diagram as “when diagram”, and the math teacher was teaching me an important lesson. Although not officially a part of the syllabus, my place within the classroom was clear. I was, as she called me, a pedhi.Kannada (Dravidian language spoken predominantly by the people of Karnataka in the southwestern

A Coreset for Approximate Furthest-Neighbor Queries in a Simple Polygon
Let $\mathcal{P}$ be a simple polygon with $m$ vertices and let $P$ be a set of $n$ points inside $\mathcal{P}$. We prove that there exists, for any $\varepsilon>0$, a set $\mathcal{C} \subset P$ of size $O(1/\varepsilon^2)$ such that the following holds: for any query point $q$ inside the polygon $\mathcal{P}$, the geodesic distance from $q$ to its furthest neighbor in $\mathcal{C}$ is at least $1-\varepsilon$ times the geodesic distance to its further neighbor in $P$. Thus the set $\mathcal{C…
