A Finite-Range, Translation-Invariant Counterexample to Weak Gibbsianity
Lorenzo Pettinari
We construct a finite-range, translation-invariant counterexample to the Weak Gibbsianity property for quantum spin systems on . The proof relies on showing how a loc…
AlignUS: MRI-Guided Ultrasound Representation Learning for ALS Classification from Tongue Images
Kadija Abdel Ghader, Emani Babe, Lorenzo Pettinari +2
Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease in which early assessment remains challenging, particularly in low-resource settings where MRI is oft…
SA-Profile: Automated Sulcus Angle Profiling from Super-Resolution MRI
Michael Wehrli, Leo Widmer, Edwin Li +5
Trochlear dysplasia (TD) is an abnormality of the femoral trochlea associated with anterior knee pain and patellar instability. The sulcus angle (SA) is used to assess trochlear mo…
Coupling of the continuum and semiclassical limit. Part I: convergence of eigenvalues
Matthias Keller, Lorenzo Pettinari, Christiaan J. F. van de Ven
We analyze the semiclassical -dimensional Schrödinger operator in the continuum discretized on a mesh with spacing proportional to . The semi-clas…
Damping of phonons in Bose gas at low temperatures
Jan Dereziński, Lorenzo Pettinari
We consider a homogeneous Bose gas in a large cubic box with periodic boundary conditions interacting with a small potential with a positive Fourier transform. We compute the imagi…
End2Reg: Learning Task-Specific Segmentation for Markerless Registration in Spine Surgery
Lorenzo Pettinari, Sidaty El Hadramy, Michael Wehrli +4
Intraoperative navigation in spine surgery demands millimeter-level accuracy. Currently, this is achieved through radiation-intensive intraoperative imaging and bone-anchored marke…
Subcriticality at High Temperatures in Spin Lattice Systems
Nicolò Drago, Lorenzo Pettinari, Christiaan J. F. van de Ven
We provide new sufficient conditions for subcriticality of classical and quantum spin lattice systems, formulated in terms of the uniqueness of Kubo-Martin-Schwinger (KMS) states.…
On classical aspects of Bose-Einstein condensation
Lorenzo Pettinari
Berezin and Weyl quantization are renown procedures for mapping, commutative Poisson algebras of observables to their non-commutative, quantum counterparts. The latter is famous fo…
Classical and quantum KMS states on spin lattice systems
Nicolò Drago, Lorenzo Pettinari, Christiaan J. F. van de Ven
We study the classical and quantum KMS conditions within the context of spin lattice systems. Specifically, we define a strict deformation quantization (SDQ) for a -v…
