Recurrence Risk in Lateralized Floor of Mouth Carcinoma: Depth of Invasion Versus Midline Distance

Head &Neck, EarlyView.
ABSTRACT Background Contralateral nodal recurrence in lateralized floor‐of‐mouth squamous cell carcinoma (OSCC) remains difficult to predict, and objective preoperative parameters to guide contralateral neck management in tumors without midline crossing are lacking.

Hybrid polarimetry inverse synthetic aperture radar

IET Radar, Sonar & Navigation
The inverse synthetic aperture radar (ISAR) system exploits the movement of the target to form its high‐resolution image. Further, the multi‐polarisation acquisition in ISAR collects additional information on the target's scattering properties and ...

Variability and uncertainty in measuring sea surface temperature

, 2012
Sea Surface Temperature (SST) measurement is one of the most easily obtainable climate variables. However, it is challenging to meet the required absolute accuracy and long term stability whether the data are derived by in situ or satellite measurements.

Minced cartilage implantation provides comparable outcomes to autologous chondrocyte implantation (ACI) for knee cartilage lesions: A matched‐pair analysis

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare short‐term patient‐reported outcomes (PROMs) and revision rates between autologous hand‐minced cartilage implantation (MCI) and autologous chondrocyte implantation (ACI) for knee cartilage lesions. Methods All patients undergoing MCI or ACI at a single centre were retrospectively analysed from a prospectively maintained ...

Managing the meniscus part I—Anatomy, biomechanics, and treatment strategies for the atraumatic meniscus tear

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The purpose of this article is to serve as the first of a two‐part review on the meniscus; in this review, we will establish the background on anatomy and pathogenesis of the meniscus, as well as the effect of the meniscus on native knee kinematics and function.

Managing the meniscus Part 2: Traumatic tear patterns, biologic augmentation, transplantation, innovation and future research

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Acute, traumatic meniscus tears are common and should be repaired whenever possible. However, the biological age of the patient, along with the specific tear morphology, may significantly influence the selection of the repair technique, expected clinical outcomes and the postoperative rehabilitation protocol.

A Self-Supervised Feature Point Detection Method for ISAR Images of Space Targets

Remote Sensing
Feature point detection in inverse synthetic aperture radar (ISAR) images of space targets is the foundation for tasks such as analyzing space target motion intent and predicting on-orbit status. Traditional feature point detection methods perform poorly
