faculty_hiring_us: Faculty hiring networks in the US (2022)
Networks of faculty hiring for all PhD-granting US universities over the decade 2011–2020. Each node is a PhD-granting institution, and a directed edge (i,j) indicates that a person received their PhD from node i and was tenure-track faculty at node j during time of collection (2011-2020). This dataset is divided into separate networks for all 107 fields, as well as aggregate networks for 8 domains, and an overall network for …

The first half of 2026 was the 5th warmest on record here in the central Netherlands.
Just following the forecast for the coming 2 weeks, and then the 1991-2020 average (cool by now) would already bring this year into the top-3 warmest since 1901.

Vaak ben ik het wel met Yusibov eens, maar in dit geval niet. De oorlog winnen en een sterke Poetin in het zadel houden in 2022 had niets opgelost.
Rusland moet uiteindelijk zien dat Poetin geen oplossing biedt. De oorlog die Oekraïne nu naar Rusland brengt kan daar hopelijk het nodige aan bijdragen.
De oorlog van dit moment was in 2022 niet mogelijk.

In the Summer of 2022, Greek politician Stelios Kouloglou was investigating how intrusive spyware had been used to hack business leaders, law enforcement officials, and politicians.
As part of the European Parliament’s PEGA Committee,
set up to investigate the use of the notorious Pegasus spyware and other variants,
Kouloglou travelled to interview spyware victims and probe high-profile cases.
That fall, according to a new forensic analysis,

EU Politicians Investigated Pegasus Spyware. Then It Ended Up on One of Their Phones
“It is a direct attack on the rule of law,” says one European Parliament member of the new findings from Citizen Lab.

Cheeger Inequalities for the Persistent Laplacian
Magnus Bakke Botnan, Rui Dong
https://arxiv.org/abs/2606.02846 https://arxiv.org/pdf/2606.02846 https://arxiv.org/html/2606.02846
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).
