In case you need to buy a new vacuum cleaner, I've found a potentially useful review. It's opinionated.

Leifheit Regulus PowerVac 2in1
Is it a bird? Is it a plane? NO! It's an opinionated and excellent review of the Leifheit Regulus PowerVac 2in1 (possibly a specific sub-version? Who knows, with these things) vacuum cleaner.

Diagnosing Altermagnetic Phases through Quantum Oscillations
The recently delimited altermagnetic phase is characterized by zero net magnetization but momentum-dependent collinear spin-splitting. To explore the intriguing physical effects and potential applications of altermagnets, it is essential to analyze their Fermi surface properties, encompassing both configurations and spin textures. Here, we conduct a Fermiology study on metallic altermagnets and demonstrate that the collinear spin-split features of their Fermi surfaces can be clearly revealed th…

Multi Higgs production via photon fusion at future multi-TeV muon colliders
Multi-TeV muon colliders promise an unprecedented potential for exploring the particle-physics energy frontier, and, at the same time, can probe with fantastic accuracy the precise structure of the Standard Model, and in particular of the Higgs boson sector. Here we consider the possibility to measure the loop-suppressed single-, double-, triple-Higgs boson production mediated by the collinear-photon scattering in the channels $μ^+μ^-\toμ^+μ^-γ^\ast γ^\ast \to μ^+μ^- [H,HH,HHH]$. We stu…

Long-term Effects of India's Childhood Immunization Program on Earnings and Consumption Expenditure: Comment
Summan, Nandi, and Bloom (2023), hereafter SNB, find that exposure during infancy to India's Universal Immunization Programme (UIP) increased wages and per-capita household expenditure in early adulthood. SNB regress these outcomes on a treatment indicator that depends upon year and district of birth while controlling for age at follow-up. Because year of birth and age are nearly collinear, SNB's identifying variation does not come from the staggered introduction of the UIP, but rather from the…

A Rydberg atom based system for benchmarking mmWave automotive radar chips
Rydberg atomic sensors and receivers have enabled sensitive and traceable measurements of RF fields at a wide range of frequencies. Here we demonstrate the detection of electric field amplitude in the extremely high frequency (EHF) band, at $131\ \mathrm{GHz}$. In our approach we propagate the EHF field in a beam, with control over its direction and polarization at the detector using photonic waveplates. This way, we take advantage of the highest detection sensitivity, registered for collinear …
