Understanding the Workflows in Dynamic and Robotic Computer‐Assisted Implant Surgery

Clinical and Experimental Dental Research, Volume 12, Issue 4, August 2026.
ABSTRACT Computer‐assisted implant surgery (CAIS) represents a comprehensive digital workflow integrating prosthetically driven planning with various execution modalities. Among these, dynamic (d‐CAIS) and robotic (r‐CAIS) systems constitute two distinct yet interrelated approaches, sharing core technological principles as well as operative differences.

Early Horizontal Deceleration Ability Across Multiple Steps and Approach Speeds in Multidirectional Team Sport Athletes

European Journal of Sport Science, Volume 26, Issue 8, August 2026.
ABSTRACT Horizontal deceleration ability (HDA) is a critical component of multidirectional team sport performance. This study aimed to identify the interaction between external kinetic and kinematic determinants of HDA across multiple deceleration steps and approach speeds. Nineteen multidirectional team sport athletes completed five maximal horizontal

Development of a gene-editing strategy to overcome genetic intractability in Lactobacillus johnsonii

Journal of Bacteriology
Genetic editing in lactobacilli is often constrained by their robust defense mechanisms against foreign DNA and low transformation efficiency, resulting in pronounced species- and strain-specific variability in the performance of genetic tools.

Markerless motion capture of man-machine interaction

2008 IEEE Conference on Computer Vision and Pattern Recognition, 2008
This work deals with modeling and markerless tracking of athletes interacting with sports gear. In contrast to classical markerless tracking, the interaction with sports gear comes along with joint movement restrictions due to additional constraints: while humans can generally use all their joints, interaction with the equipment imposes a coupling ...

Accentuated Eccentric Loading Increases Maximal Countermovement Jump Height Without Changes in Overall Lower Limb Kinetics and Energetics

European Journal of Sport Science, Volume 26, Issue 8, August 2026.
ABSTRACT This study aimed to determine the mechanical and energetic responses to accentuated eccentric loading (AEL) during maximal countermovement jumps (CMJ) and examined potential mechanisms underlying performance enhancement relative to bodyweight CMJs.

Markerless tracking using planar structures in the scene

Proceedings IEEE and ACM International Symposium on Augmented Reality (ISAR 2000), 2002
We describe a markerless camera tracking system for augmented reality that operates in environments which contain one or more planes. This is a common special case, which we show significantly simplifies tracking. The result is a practical, reliable, vision-based tracker.

Integrating Augmented Reality Into Otologic Cadaveric Surgical Training

The Laryngoscope, Volume 136, Issue 8, Page 3569-3576, August 2026.
This pilot study developed and implemented a specimen‐specific augmented reality (AR) workflow for cadaveric temporal bone dissection, using CT‐derived 3D models registered to each specimen and viewed intermittently through a Microsoft HoloLens 2 headset.

Time‐resolved PET imaging using a joint dynamic reconstruction and motion estimation framework (DREME‐PET)

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Positron emission tomography (PET) plays a critical role in image‐guided radiotherapy by enabling accurate tumor localization and contouring. To account for respiration‐induced anatomical motion, time‐resolved PET imaging is highly desirable, as it captures dynamic anatomical variations to facilitate both disease diagnosis and ...

A Deep Learning Model for Markerless Pose Estimation Based on Keypoint Augmentation: What Factors Influence Errors in Biomechanical Applications?

Sensors
In biomechanics, movement is typically recorded by tracking the trajectories of anatomical landmarks previously marked using passive instrumentation, which entails several inconveniences.
