Preservation of stability under the Fourier-Mukai transform whose kernel is the Poincare line bundle
For a Fourier-Mukai transform whose kernel is the Poincare line bundle, we study the preservation of Gieseker stability of sheaves on any abelian surface.

Discrete Poincaré inequalities and universal approximators for random graphs
Nonlinear Poincaré inequalities are indispensable tools in the study of dimension reduction and low-distortion embeddings of graphs into metric spaces, and have found remarkable algorithmic applications. A basic open problem, posed by Jon Kleinberg (2013), asks whether the optimal nonlinear Poincaré constant for maps between two independent $3$-regular random graphs is dimension-free, i.e., independent of vertex-set sizes. We give a complete and affirmative resolution to Kleinberg's problem, …

Cosmology of Cubic Poincaré Gauge gravity
In this paper, we study flat FLRW cosmology for a Poincaré gauge theory containing cubic invariants that is free from ghosts in arbitrary backgrounds in the axial and vector sectors of the torsion tensor. The new degrees of freedom can be related to hypermomentum but continue to be dynamical even in vacuum. These extra degrees of freedom open a more natural way in which to construct potential gravitational models that provide possible ways to modify astrophysical and cosmological physics. In t…

In silico evaluation of pramlintide dosing algorithms in artificial pancreas systems
Pramlintide's capability to delay gastric emptying has motivated its use in artificial pancreas systems, accompanying insulin as a control action. Due to the scarcity of pramlintide simulation models in the literature, in silico testing of insulin-plus-pramlintide strategies is not widely used. This work incorporates a recent pramlintide pharmacokinetics/pharmacodynamics model into the T1DM UVA/Padova simulator to adjust and validate four insulin-plus-pramlintide control algorithms. The proposa…

Asymmetry in momentum space: restoring CPT invariance of $κ$-field theory
The positive and negative energy modes of a field theory in $κ$-Minkowski/$κ$-Poincaré noncommutative spacetime have very different symmetry properties. This can be understood geometrically by considering that they span two distinct sectors of a curved momentum space. It seems that because of this asymmetry, charge conjugation and Poincaré invariance are incompatible. However, the structure of momentum space suggests that time reversal could be deformed so that the overall CPT-invariance is…

Rådgivningen skiljer sig en del från Småspararguiden, särskilt den enorma känsligheten kring skuld (Småspararguiden säger att man ska undvika att överamortera och istället placera sina pengar) men mycket är gemensamt. Särskilt fokuset på stora, stabila aktiefonder https://www.youtube.com/watch?v=V360AygOv7

Spain were the better side and deservedly advance to the final. They just had more of everything, able to bring on players and punish a fatigued and thin Germany.
But Germany didn't make it easy. They were outstanding defensively and had a puncher's chance on several counters that they were unable to capitalize on.
Berger was fantastic, preventing 1.23 goals. But one mistake cost Germany dearly. Cruel sport, sometimes.

ResearcherBench: Evaluating Deep AI Research Systems on the Frontiers of Scientific Inquiry
The emergence of deep research systems presents significant capabilities in problem-solving, extending from basic queries to sophisticated research tasks. However, existing benchmarks primarily evaluate these systems as agents for web retrieval and report generation, overlooking their potential to discover novel insights on the frontiers of scientific research. To address this gap, we introduce ResearcherBench, the first benchmark focused on evaluating the capabilities of these advanced, agenti…
