Digitalization of operative procedures through three-dimensional (3D) navigation is a remarkable advancement in the field of dentistry which allows both precision and accuracy while treating patients. It is an emerging technology with a wide variety of applications in dentistry. In the field of endodontics, these computer-aided 3D systems are being used for accessing and localizing canals in calcified teeth, removal of fiberglass posts, and in peri-apical surgeries etc. Preservation of important anatomical structures becomes necessary while performing root-end resection or peri-apical surgeries. However, it is clinically difficult to achieve accurate root-end resection due to the limited field of view, inconvenient perspective, and interferential bleeding among other factors. 3D guided endodontics play vital role here. 3D guided endodontics can be achieved in two ways- Static and Dynamic navigation. Due to availability of limited literature, there is a need to review new evidence comparing the effectiveness of both techniques of 3D guided endodontic navigation systems. This review paper describes the comparative evaluation of the effectiveness of static as well as dynamic navigation in the field of endodontic microsurgery.

Harbor seals possess a remarkable ability to detect hydrodynamic footprints left by moving objects, even long after the objects have passed, through interactions between wake flows and their uniquely shaped whiskers. While the flow-induced vibration (FIV) of harbor seal whisker models has been extensively studied, their response to unsteady wakes generated by upstream moving bodies remains poorly understood. This study investigates the wake-induced vibration (WIV) of a flexibly mounted harbor seal-inspired whisker positioned downstream of a forced-oscillating circular cylinder, simulating the hydrodynamic footprint of a moving object.

This commentary examines the learnings from different countries included in the Special Series: . Studies focused on the initial phase of the GFF and highlighted key themes, including power asymmetries, stakeholder engagement, the alignment of funding to health needs, and the treatment of community health and quality of care within GFF-supported programs. This commentary reflects on policy processes and health financing dynamics emerging from the papers in the Special Series and examines what it means for the new strategy in development by the GFF.

The 2022 Supreme Court of the United States' decision in Dobbs v. Jackson Women's Health Organization eliminated federal abortion protections, returning abortion regulation to the states. However, in many states, abortion was already heavily restricted prior to this decision.

Purpose: Gadoxetic acid-enhanced hepatobiliary phase T-weighted (Tw) MRI is effective for the detection of focal liver lesions but lacks sufficient T contrast to distinguish benign from malignant lesions. Although the addition of T, diffusion, and dynamic contrast-enhanced Tw imaging improves lesion characterization, these methods often do not provide adequate spatial resolution to identify subcentimeter lesions. This work proposes a high-resolution, volumetric, free-breathing liver MRI method that produces colocalized fat-suppressed, variable Tw images from a single acquisition, thereby improving both lesion detection and characterization.

Animals can improve their decision-making abilities by integrating information from multiple senses, which is especially beneficial when living in fluctuating environments. However, understanding how wild predators may use multimodal sensing when hunting prey in split-second interactions remains largely unexplored. As nocturnal hunters, bats rely on echolocation to navigate and to locate evasive prey, yet they have retained functional vision, despite the associated costs.
