Improved respiratory motion tracking through a novel fiducial marker placement guidance system during electromagnetic navigational bronchoscopy (ENB)

Radiation Oncology, 2019
Background Stereotactic ablative radiotherapy (SABR) is a treatment option for patients with early stage non-small cell lung cancer (NSCLC) and recurrent or oligometastatic disease who are not surgical candidates.

Grooved Surface of the Obturator Internus Muscle With Two Distinct Adjacent Parts

Clinical Anatomy, EarlyView.
ABSTRACT The specific anatomical features of the obturator internus, particularly those of its medial surface, remain insufficiently characterized. This study investigated the morphology of the obturator internus muscle by focusing on the shape of its medial surface and potential age‐related changes.

Presentation Assistant and Kiosk Interaction with Fiducial Markers

2007 IEEE International Workshop on Haptic, Audio and Visual Environments and Games, 2007
Fiducial markers and computer vision software provide a low cost and flexible way for human-computer interaction. Using the high reliability and minimal image pixel requirements of the ARTag fiducial marker system we are able to identify users and perform control actions with a simple small printed pattern. We describe two novel applications.

Preclinical Serial Assessment of Virtual Physiology After Implantation of a Novel Endoluminal Resorbable Fibrillated Scaffold

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The resorbable fibrillated scaffold (RFS) is a novel electrospun, polylactide‐based endoluminal scaffold developed for peripheral arterial applications. Its porous microfibre architecture is intended to support host cell infiltration and vascular restoration.

Investigating the Cytoskeleton of DRGs Using Cryo‐Electron Microscopy and Deep Learning

Cytoskeleton, EarlyView.
ABSTRACT We describe a method for determining the ultrastructural organization of axons and varicosities of cultured dorsal root ganglion (DRG) neurons using cryogenic electron microscopy (cryo‐EM). Cryo‐EM reveals the dimensions, proximity, and overall organization of biological specimens in a near‐native state, avoiding artifacts of fixation and ...

Sparse Indoor Camera Positioning with Fiducial Markers

Applied Sciences
Accurately estimating the pose of large arrays of fixed indoor cameras presents a significant challenge in computer vision, especially since traditional methods predominantly rely on overlapping camera views.

FidMark: A Fiducial Marker Ontology for Semantically Describing Visual Markers

Fiducial markers are visual objects that can be placed in the field of view of an imaging sensor to determine its position and orientation, and subsequently the scale and position of other objects within the same field of view. They are used in a wide variety of applications ranging from medical applications to augmented reality (AR) solutions where ...

Double Sided Traction Force Microscopy: A Method to Confine Cells for Physiologically Relevant Force Measurements

Cytoskeleton, EarlyView.
ABSTRACT In this paper we describe a technique to make a confined environment of variable stiffness that is suitable for high‐resolution live‐cell imaging. This versatile and adaptable technique enables cell confinement between soft elastic surfaces made from polyacrylamide gels.

CEO Overconfidence, Industry Competition, and ESG Performance

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study examines the interplay among CEO overconfidence, industry competition, and firms' ESG (Environmental, Social, and Governance) performance. With the growing importance of ESG management, firms are investing more in ESG initiatives as a strategic approach to mitigating downside risk. However, overconfident CEOs, characterized by their
