Large language models excel at text extraction, but they sometimes hallucinate. A simple way to avoid hallucinations is to remove any extracted text that does not appear in the original source. This is easy when the extracted text is contiguous (findable with exact string matching), but much harder when it is…

This paper presents experimental results that allow for the performance evaluation of a straight-line reference alignment system based on pseudo-nondiffracting Layer beams. Sensors, developed specifically for this system, feature four linear CMOS chips and a square aperture. This allows for simultaneous measurements…

'J Eberhardt' 'E Franceschetti' 'D Jeremic' 'A Klasan' 'P A Vendittoli' 'G M Avram'] 1. The main goal of a successful total knee arthroplasty is to relieve pain and restore function. While mechanical alignment provides excellent long-term implant survivorship, clinical and functional outcomes remain less than ideal. 2.…

— Aligning a lens system relative to an imager is a critical challenge in camera manufacturing. While optimal alignment can be mathematically computed under ideal conditions, real-world deviations caused by manufacturing tolerances often render this approach impractical. Measuring these tolerances can be costly or even…

'J Eberhardt' 'E Franceschetti' 'D Jeremic' 'A Klasan' 'P A Vendittoli' 'G M Avram'] 1. Total knee arthroplasty is a highly effective intervention for end-stage osteoarthritis, yet nearly 20% of patients report dissatisfaction with clinical outcomes. 2. This dissatisfaction is often linked to intraoperative parameters…

Given a set of overlapping local views (patches) of a dataset, we consider the problem of finding a rigid alignment of the views that minimizes a 2-norm based alignment error. In general, the views are noisy and a perfect alignment may not exist. In this work, we characterize the non-degeneracy of an alignment in the…

In molecular machine learning, the choice of the representation of molecules can have a significant impact on model performance. However, understanding the root causes of these performance differences often proves challenging. One promising approach to explore model behavior is representational alignment, which…

There exist elegant methods of aligning point clouds in R 3 . Unfortunately, these methods fail to generalize to the case of Minkowski space, as we will show. Instead, we propose two solutions to the following problem: given inertial reference frames A and B, and given (possibly noisy) measurements of a set of…

Temporal alignment is an inherent task in most applications dealing with videos: action recognition, motion transfer, virtual trainers, rehabilitation, etc. In this paper we dive into the understanding of this task from a geometric point of view: in particular, we show that the basic properties that are expected from a…

Knee alignment plays a pivotal role in the outcomes of total knee replacement (TKR), influencing postoperative function, pain reduction, and long-term implant longevity. Over the past few decades, various knee alignment philosophies have been proposed to optimize surgical results, including the mechanical axis and…

Tissue engineering and regenerative medicine applications require the integration of multifunctional materials, offering appropriate mechanical cues and geometric guidance to support tissue-specific cell differentiation. In this context, supramolecular gel noodles formed by ionic cross-linking of pre-assembled micellar…

Total knee arthroplasty (TKA) alignment has recently become a hot topic in the orthopedics arthroplasty literature. Coronal plane alignment especially has gained increasing attention since it is considered a cornerstone for improved clinical outcomes. Various alignment techniques have been described, but none proved to…

To show the reproducibility of the collimator axes for computing physical isocenter, five iMarc datasets were acquired and the standard deviation of the location and radius were computed. For couch alignment, optical data for both clockwise and counter-clockwise couch rotations were acquired and the average of the two…

Cell alignment is a fundamental process in development and plays an essential role in tissue function. Although it has been found that cell alignment exhibits a density-dependent collective behavior, the collective mechanisms within this process remain elusive. In this study, we present a model of collective cell…

Machine learning models are increasingly applied to heterogeneous materials datasets spanning different synthesis routes, measurement protocols, and structural classes. Although multi-task and representation-learning approaches are commonly used to improve predictive performance, the latent representations learned by…

The intersection of chemistry and Artificial Intelligence (AI) is an active area of research focused on accelerating scientific discovery. While using large language models (LLMs) with scientific modalities has shown potential, there are significant challenges to address, such as improving training efficiency and…

The healthy human eye’s optical components are misaligned. Although important in studying vision quality, it has been overlooked in research on binocular and oculomotor vision. This study presents the construction of ocular torsion in the binocular system that incorporates the fovea displaced from the posterior pole…

The brain uses two slightly different 2D retinal images to enhance our vision with stereopsis, i.e., spatial depth and 3D shape. Stereopsis is organized by pairs of corresponding retinal elements of zero disparity: a small retinal area in one eye and the corresponding unique area in the other share one subjective…

Pose prediction of ligands to proteins remains a central challenge of structure-based drug design. Although data leakage and generalizability concerns remain, data-driven methods for pose prediction (i.e. based on deep learning and diffusion) now routinely outperform traditional techniques such as molecular docking. In…

In this work, we present a fully automated method for the construction of chemically meaningful sets of non-redundant internal coordinates (also commonly denoted as Z-matrices) from the cartesian coordinates of a molecular system. Particular focus is placed on avoiding ill-definitions of angles and dihedrals due to…

We introduce several modifications of conic fitting in Geometric algebra for conics by incorporating additional conditions into the optimisation problem. Each of these extra conditions ensure additional geometric properties of a fitted conic, in particular, centre point position at the origin of coordinate system…
