Auf ihren Einwand, das sei kein Beweis, beschimpft er NBC, ABC, CBS & CNN als „krumme Sender" und geht. Belege? Wie immer: keine. NBC stufte danach mehrere Aussagen als falsch ein. Schon 2022 lief ein NPR-Interview genauso.

Cheeger Inequalities for the Persistent Laplacian

arXiv:2606.02846v1 Announce Type: new
Abstract: We study Cheeger-type inequalities for persistent Laplacians associated with inclusions of simplicial complexes $\mathcal{K}\hookrightarrow \mathcal{L}$. We introduce a persistent up $p$-Laplacian $\Delta_{q,p,\mathrm{up}}^{\mathcal{K},\mathcal{L}}$ for $p\geq 1$. For $p=2$, this recovers the usual persistent up Laplacian, while for $p=1$ it yields a nonzero persistent Cheeger constant $\varphi_q^{\mathcal{K},\mathcal{L}}$. We prove a Cheeger-type inequality relating $\varphi_q^{\mathcal{K},\mathcal{L}}$ to the smallest nonzero eigenvalue of $\Delta_{q,\mathrm{up}}^{\mathcal{K},\mathcal{L}}$. This gives a persistent extension of recent work by Jost and Zhang (Ann. Sc. Norm. Super. Pisa Cl. Sci., 2024; arXiv:2302.01069).
We then study two more structured settings. Under a locally complete $q$-skeleton assumption on $\mathcal{K}$, we extend the complete-skeleton isoperimetric inequality of Parzanchevski--Rosenthal--Tessler (Combinatorica, 2016; arXiv:1207.0638) to the persistent setting. For orientable $(q 1)$-dimensional pseudomanifolds, we prove a Kron-type reduction of the persistent up Laplacian to a vertex- and edge-weighted graph Laplacian, possibly with Dirichlet boundary terms, and obtain two-sided Cheeger inequalities; this is related to the dual-graph perspective in the work of Steenbergen--Klivans--Mukherjee (Adv. Appl. Math., 2014; arXiv:1209.5091). We also describe the nonzero persistent Cheeger constant $\varphi_q^{\mathcal{K},\mathcal{L}}$ explicitly in terms of the dual graph in the non-branching pseudomanifold case. Finally, for graph inclusions $H\hookrightarrow G$, we compare the persistent Cheeger constants introduced here with the Kron-reduction Cheeger constants of M\'emoli et al. (SIAM J. Math. Data Sci., 2022; arXiv:2012.02808).

Putin just unleashed a nuclear-capable ballistic missile in the heart of Ukraine’s capital, Kyiv.
This was part of one of the biggest attacks on the capital since the start of Russia’s war in 2022.
And the Russians say this is just the “beginning” of a new wave of strikes on “decision-making centers” in Kyiv.
And what has Trump or Vance or even Rubio said?

Instead, last week they extended the waiver of sanction…
RE: #bavovna
'On 25 April 2022, during the Russian invasion of Ukraine, explosions rang out at a military base and an oil depot in the Russian city of Bryansk.[3] As per the Russian government standards, Russian media reported the explosion as a khlopok, a "pop".[1] However, when the announcement was translated into the Ukrainian language, the machine translation program confused the identically written words for "pop" and "cotton", and translated khlopok into Ukrainian as bavovna (Ukrainian: бавовна), a word which unambiguously means "cotton".[4][5] '

Animal dominance interaction data published over a century of research. The archive contains 434 agonistic interaction datasets, totaling over 241,000 interactions. A directed edge (i,j) corresponds to an antagonist interaction between i (winner) and j (loser). If a 'weight' edge property map exists, it counts the number of such interactions.
This network has 15 nodes and 83 edges.

Heute vor 3 Jahren: Am 14. Juni 2023 erklärte der belarussische Präsident Aleksander Lukaschenko in einem Fernsehinterview mit dem russischen Staatssender Russia-1, dass #Belarus, wie am 25.03.23 durch Putin angekündigt, #Kernwaffen von Russland erhalten habe.
Just did very approximate calculations; with 10g of lithium per drone*, and assuming the Russian and Ukrainian drone efforts consume 5m units a year**, that'd be ~50 tons of lithium deposited into the environment per year, mostly within, let's say, 50km of the grey zone***. It's only about $20,000 / ton****, which means $1m of metal*****.
So to answer my own silly question: no, it won't be economically viable to scalp the top few inches of topsoil and extract the lithium from it.
* Roughly right for quadcopters / small FPV; larger and longer range ones will have more, so this is a bottom bound. (OTOH longer range UAVs will tend to use ICE kerosene rather than batteries
** Changing all the time as both sides try expanding production as fast as they can manage. Ua are scaling much faster at time of writing
*** Handwaving. Contact zone's hardly moved since early 2023; OTOH Ua are pushing range limits on small battery-powered form factor, saw a 60km claim for the Logistics Lockdown operation the other day
**** There was a big spike to the $70-8000 range in 2022; median price is closer to $10k than $20k
***** (IDK the chemistry but presumably it's in an exciting range of different compounds, depending on how many bits the battery was blown into, how hot / pressured the blast wave was a few tens of mm from the boom, what other stuff was in the vicinity that the lithium would combine with, etc etc.

My water bill came in recently, which is kind of appropriate considering all the pond talk.
Since building it, the front yard #pandemicPond very very rarely is topped up on its own from tap water. Generally we keep it full from rain water, the rain barrel, or as part of the general low-flow spray/water system for the yard in the summer. So our water consumption really is dependant on how much garden watering we are doing. I'm not surprised we were high last year as we watered the new green-driveway and young trees.
The #PoolPond might, or might not, be different given the sheer volume *and* surface area (ie. evaporation). We have a 1000L rainwater barrel in the back yard, but that would only be useful for replacing evaporation losses at best in the poolpond.
I'll have to fill it once or twice in the coming weeks and possibly once a year if I do an annual cleaning at the end of the summer. We'll see. This year will also feature a return of vegetation to the back yard, so we'll likely be watering it more than when it is established in a year or two.
The city splits our bill into 3 periods per year, which is a little weird but ok...
Our household consumption has varied quite a bit since the pandemic due to changes in household composition (kids moving to uni etc) or us being more or less active in the garden.
I am happy that we used very little water this winter/spring, the least since 2022. I expect it to spike in the current April-August period as both kids have returned and I'll be doing all this pond stuff. But if I can keep it under 150,000L ($150) on the August bill, I'll be happy.
In the coming years, if I can use less in the Fall, Winter and Spring to "save up" for Summer, that would be nice but minimizing all seasons will always be the goal. That's why more trees are going to happen in the backyard at some point. Shade=Less watering!
In all, I'm happy with the only modest rise in our water consumption over the past few years.
