Transabdominal Fetal Oximetry via Diffuse Optics: Principled Analysis and Demonstration in Pregnant Ovine Models
Diffuse optics has the potential to offer a substantial advancement in fetal health monitoring via enabling continuous measurement of fetal blood oxygen saturation (fSpO$_2$). Aiming to enhance the sensing accuracy and to elucidate the foundational limits of Transabdominal Fetal Oximetry (TFO) via diffuse optics, we introduce a theoretical derivation, and a comprehensive pipeline for fSpO$_2$ estimation from non-invasively sensed diffuse light intensity values, which are leveraged to analyze da…

Finally uninstalled #feedly in favour of #freshRss and #capyreader. My wife is interested as well to switch.
Calendar still bugs me a bit. I could check this this weekend maybe.
When I t…

Berkenswert klares Interview mit @… zu Drohnenangriffen auf Flughäfen:
Informationen am Mittag | Kritische Infrastrukturen besser schützen: Interview mit Manuel Atug, AG Kritis

Drohnenabwehr: Durch schwache Gesetze und alte Systeme bleiben Flughäfen weiterhin wenig geschützt
Flughäfen sind verwundbar: Drohnen kreisen unbehelligt, Hacker legen Systeme lahm. Mit mehr Engagement gegen Angriffe könnten fatale Folgen verhindert werden.

Inverse Design of a Layered Medium for Maximal Surface Localization
Electromagnetic wave manipulation plays a crucial role in advancing technology across various domains, including photonic device design. This study presents an inverse design approach for a periodic medium that optimizes electromagnetic wave localization at the interface between a layered half-space and a homogeneous half-space. The approach finds a maximally localized mode at a specified frequency and wave number. The mode propagates in the direction of the interface. The design parameters are…

Uncertainty in the time of arrival of ultra high energetic neutrinos
In the light of the recent observation by the KM3NeT collaboration of an ultrahigh energetic neutrino, we analyse it in its rest frame, where shortly after creation of the neutrino a muon arrives and interacts. Since the neutrino is at rest we use (in this first analysis) a non relativistic Gaussian wave function, and consider its spread. Due to the finite size of the packet, the time of the interaction of the muon will have an uncertainty. This uncertainty is small in the neutrino rest frame, …

Non-invasive optical quantification of methanol in bottled spirits
Food and beverage contamination poses a persistent global threat. A prime example is the presence of methanol in counterfeit or illicit spirits, causing severe and often fatal poisoning worldwide. Rapid, non-destructive, and on-site screening methods capable of molecular analysis directly through commercial packaging are therefore urgently needed for quality control and consumer safety. Here, we introduce a non-invasive optical approach based on Raman spectroscopy that judiciously combines wave…

Beyond Slater's Condition in Online CMDPs with Stochastic and Adversarial Constraints
We study \emph{online episodic Constrained Markov Decision Processes} (CMDPs) under both stochastic and adversarial constraints. We provide a novel algorithm whose guarantees greatly improve those of the state-of-the-art best-of-both-worlds algorithm introduced by Stradi et al. (2025). In the stochastic regime, \emph{i.e.}, when the constraints are sampled from fixed but unknown distributions, our method achieves $\widetilde{\mathcal{O}}(\sqrt{T})$ regret and constraint violation without relyin…

The exterior derivative and the mean value equality in $\mathbb{R}^n$
This survey revisits classical results in vector calculus and analysis by exploring a generalised perspective on the exterior derivative, interpreting it as a measure of "infinitesimal flux". This viewpoint leads to a higher-dimensional analogue of the Mean Value Theorem, valid for differential $k$-forms, and provides a natural formulation of Stokes' theorem that mirrors the exact hypotheses of the Fundamental Theorem of Calculus - without requiring full $C^1$ smoothness of the differential for…

Good Morning #Canada
#HappyBirthday to Lilly Saini Singh, actor, comedian, author, television host, born on this day in 1988 in Scarborough, Ontario. As a well-known Internet personality, Lilly Singh has amassed nearly 15 million subscribers and more than 3 billion views since launching her popular channel of #YouTube videos under the name IISuperwomanII in 2010. She has since appeared as an actor in films and TV series and published the book How To Be a Bawse: A Guide to Conquering Life (2017), which topped the New York Times Business Best Sellers list. In 2017, she ranked No. 10 on Forbes’ list of the world’s highest-paid YouTube stars. And occasionally, she lampooned our American neighbours.
