Regularity of Resolutions and Limits of Manifolds with a Uniform Contractibility Function
In this paper, we give a short and self-contained proof to a 1991 conjecture by Moore concerning the structure of certain finite-dimensional Gromov--Hausdorff limits, in the ANR setting. As a consequence, one easily characterizes finite dimensional limits of PL-able or Riemannian $n$-manifolds with a uniform contractibility function. For example, one can define for any compact connected metric space that is a resolvable ANR homology manifold of covering dimension at least 5, an obstruction, whi…

Five months into its unprecedented dismantling of foreign-aid programs,
the Trump administration has given the order to incinerate food instead of sending it to people abroad who need it.
Nearly 500 metric tons of emergency food
—enough to feed about 1.5 million children for a week
—are set to expire tomorrow, according to current and former government employees with direct knowledge of the rations.
Within weeks, two of those sources told me, the food, meant for c…

On Universal Inverse Monoids with the $F$-Inverse Property
An inverse monoid $M$ is called $F$-inverse if each $σ$-class of $M$, where $σ$ is the minimum group congruence of $M$, has a maximum element with respect to the natural order of $M$. Upon Kinyon's observation made in 2018 that $F$-inverse monoids form a variety in the enriched signature involving an additional unary operation mapping each element of $M$ to the maximum element of its $σ$-class, a separate theory of $F$-inverse monoids is developing in recent years, greatly aided by a recent …

Don't Hash Me Like That: Exposing and Mitigating Hash-Induced Unfairness in Local Differential Privacy
Local differential privacy (LDP) has become a widely accepted framework for privacy-preserving data collection. In LDP, many protocols rely on hash functions to implement user-side encoding and perturbation. However, the security and privacy implications of hash function selection have not been previously investigated. In this paper, we expose that the hash functions may act as a source of unfairness in LDP protocols. We show that although users operate under the same protocol and privacy budge…

Prototype Development and Calibration of the CUbesat Solar Polarimeter (CUSP)
The space-based CUbesat Solar Polarimeter (CUSP) mission aims to measure the linear polarization of solar flares in the hard X-ray band by means of a Compton scattering polarimeter. CUSP will allow to study the magnetic reconnection and particle acceleration in the flaring magnetic structures of our star with its unprecedented sensitivity to solar flare polarization. CUSP is a project in the framework of the Alcor Program of the Italian Space Agency aimed to develop new CubeSat missions. It has…
