Cleaner, cooler and cheaper: Upgraded catalyst system achieves low-temperature oxidation
What if chemical manufacturers could cut their energy costs while eliminating toxic heavy metals from their processes? Researchers at Nagoya University have developed a catalyst system that does exactly that by converting alcohols to valuable chemical products at lower temperature using safer iodine compounds instead of dangerous heavy metals, expensive precious metals, and reagents.

Starting today, the Swiss Post sells a special stamp to commemorate the granting of the patent for the toilet cleaner with the special duck design 45 years ago to Swiss inventor Walter Düring-Orlob.
And yes, it smells like the citrus version of the cleaner.

Gauge anomalies on shell and collinear factorization
We revisit gauge anomalies from the purely on-shell perspective. We argue that violation of anomaly cancellation conditions manifests as a breakdown of collinear factorization. We explicitly construct one-loop 5-point amplitudes with graviton exchange displaying singular behavior in collinear limits that cannot be reconciled with factorization theorems. In this approach, gravity serves as a universal probe of both abelian and non-abelian anomalies.

Few observations from traveling through Switzerland and Italy.
Swiss most important job is the road engineer. It's insane how complex those roads, tunnels and bridges are.
German speaking Switzerland is like better and cleaner Germany. Italian speaking like better and cleaner Italy.
Italian TV is full of food, love and pretty people.
People are dressed much much better here than Poland. Not to even mention Germany. I only reached Milan so far tho.

Privacy Risks in Time Series Forecasting: User- and Record-Level Membership Inference
Membership inference attacks (MIAs) aim to determine whether specific data were used to train a model. While extensively studied on classification models, their impact on time series forecasting remains largely unexplored. We address this gap by introducing two new attacks: (i) an adaptation of multivariate LiRA, a state-of-the-art MIA originally developed for classification models, to the time-series forecasting setting, and (ii) a novel end-to-end learning approach called Deep Time Series (DT…

Floquet odd-parity collinear magnets
Altermagnets (AMs), recently discovered unconventional magnets distinct from ferro- and antiferromagnets, have rapidly emerged as a prominent frontier in condensed matter physics. AMs are characterized by alternating collinear magnetic moments with zero net magnetization in real space, and spin splittings with even-parity symmetry in momentum space. However, their counterparts exhibiting odd-parity spin splitting remain largely unexplored. Here, based on symmetry argument, we show that such unc…

On the Edge of Safety: Charge-Charge Correlation in the Back-to-Back Limit
We investigate the Charge-Charge Correlation (QQC) in electron-positron annihilation as a probe of charge dynamics in Quantum Chromodynamics. While generally divergent beyond leading order, we show that the QQC is infrared and collinear safe in the back-to-back limit, a property that we dub leading-power safety. This enables an analytic perturbative treatment that bypasses the reliance on non-perturbative track or fragmentation functions. Using Soft-Collinear Effective Field Theory, we derive a…

I just published a post on an interesting MSc thesis I supervised. Arvid Rydberg and Selina Sand Engberg took on the computational challenge of level-p-complexity (D_p(f)) of Boolean functions.
They optimised the algorithms using hash-consing & normalisation, and developed tools for exact calculations using algebraic numbers.
