Compartment Syndrome following Open Femoral Fracture with an Isolated Femoral Vein Injury Treated with Acute Repair
Acute compartment syndrome is a surgical emergency and its diagnosis is more difficult in obtunded or insensate patients. We present the case of a 34-year-old woman who sustained a Gustilo-Anderson grade III open midshaft femur fracture with an isolated femoral vein injury treated with direct…

Fast dynamical simulation combining harmonic-modal hybrid formulations with space separated representations
In our previous works, we addressed degenerated 3D domains by proposing the use of Proper Generalized Decomposition (PGD)-based separated representations, enabling efficient and accurate resolutions in complex geometries. Separately, we also developed a harmonic-modal analysis approach that…

Early Definitive Fixation of an Open Periprosthetic Femur Fracture in the Polytraumatized Patient: A Case Report and Review of the Literature
INTRODUCTION: Periprosthetic fractures of the femur after total hip arthroplasty are increasing in frequency. In the polytraumatized patient with long-bone fracture, an ongoing debate exists regarding early definitive stabilization versus initial damage control orthopaedics, followed by delayed…

RRAEDy: adaptive latent linearization of nonlinear dynamical systems
Abstract Many existing latent-space models for dynamical systems require the latent dimension to be fixed in advance, rely on tuning loss functions to approximate linear dynamics, and do not regularize the latent variables. We introduce RRAEDy, a model that overcomes these limitations by…

Damage detection algorithm based on an innovative nonlinear model-order reduction technique: the Rank Reduction Autoencoder (RRAE) conditioned to learn damage features.
Structural Health Monitoring (SHM) aims to monitor in real-time the health state of engineering structures. For thin structures, Lamb Waves (LW) are very efficient for SHM purposes. A bonded piezoelectric transducer (PZT) emits LW in the structure in the form of a short tone burst. This initial…

Social disadvantage outweighs knowledge in dementia risk
INTRODUCTION: Public health efforts promote dementia knowledge to reduce risk, but it is unclear whether knowledge predicts lower risk compared to social determinants like education and socioeconomic status (SES). METHODS: We analyzed cross‐sectional data from 1730 adults to examine how age, sex…

Application of survival analysis to model proliferation likelihood of Escherichia coli biofilm following laser-induced hyperthermia treatment
Eighty percent of bacterial infections associated with living tissue and medical devices are linked to drug-resistant biofilms, leading to lengthy and costly recoveries. Laser-induced hyperthermia can disrupt cell proliferation within biofilms and increase susceptibility to antibiotics. However…

Data-driven discovery of roughness descriptors for surface characterization and intimate contact modeling of unidirectional composite tapes
Unidirectional tape surface roughness determines the evolution of the degree of intimate contact required for ensuring thermoplastic molecular diffusion and the associated inter-tape consolidation during the manufacturing of composite structures. However, the usual characterization of rough…

Descending Necrotizing Mediastinitis, When Mediastinal Drainage By Thoracoscopy Is Not Sufficient: Case Report and Review of the Literature
Introduction: Descending necrotizing mediastinitis (DNM) is an acute infection of the mediastinum secondary to odontogenic, pharyngeal, or cervical infections that extend into the deep cervical spaces and progress into the mediastinum. This case report and literature review aim to contribute to the…

A hybrid twin based on machine learning enhanced reduced order model for real-time simulation of magnetic bearings
Abstract The simulation of magnetic bearings involves highly non-linear physics, with high dependency on the input variation. Moreover, such a simulation is time consuming and can’t run, within realistic computation time for control purposes, when using classical computation methods. On the other…

Manifestation of depression in speech overlaps with characteristics used to represent and recognize speaker identity
Abstract The sound of a person’s voice is commonly used to identify the speaker. The sound of speech is also starting to be used to detect medical conditions, such as depression. It is not known whether the manifestations of depression in speech overlap with those used to identify the speaker. In…

Remaining useful life of power transformers using efficient surrogates and deep learning techniques
Abstract The assessment of remaining useful life (RUL) in power transformers (PTs) is critical, given their essential role in the reliable distribution of electrical energy. According to international standards, the RUL is primarily influenced by the temperature of the hotspot (HST) located near…
