      Identifying predictive factors for an outcome of interest via a multivariable analysis is often difficult when the data set is small. Combining data from different medical centers into a single (larger) database would alleviate this problem...

      Depth- and Semantics-aware Multi-modal Domain Translation: Generating 3D Panoramic Color Images from LiDAR Point Clouds

      Computer Vision and Pattern Recognition
      This work presents a new depth- and semantics-aware conditional generative model, named TITAN-Next, for cross-domain image-to-image translation in a multi-modal setup between LiDAR and camera sensors. The proposed model leverages scene sema...

      In this paper, we extend a classical vanishing result of Burnside from the character tables of finite groups to the character tables of commutative fusion rings, or more generally to a certain class of abelian normalizable hypergroups. We a...

      Discovery of Atomic Clock-Like Spin Defects in Simple Oxides from First Principles

      Physics
      Materials Science
      Virtually noiseless due to the scarcity of spinful nuclei in the lattice, simple oxides hold promise as hosts of solid-state spin qubits. However, no suitable spin defect has yet been found in these systems. Using high-throughput first-prin...

      A regularity theory for an initial value problem with a time-measurable pseudo-differential operator in a weighted LpL_pLp​-space

      Mathematics
      Analysis of PDEs
      In this study, we investigate the existence, uniqueness, and maximal regularity estimates of solutions to homogeneous initial value problems involving time-measurable pseudo-differential operators within the framework of weighted mixed norm...

      We use weighted unfoldings of quivers to provide a categorification of mutations of quivers of types I2(2n)I_2(2n)I2​(2n), thus extending the construction of categorifications of mutations of quivers to all finite types....

      The Nelson model, describing a quantum mechanical particle linearly coupled to a bosonic field, exhibits the infrared problem in the sense that no ground state exists at arbitrary total momentum. However, passing to a non-Fock representatio...
