Scanning Parametric Sediment Echosounder as Tool for Underwater Archaeological Prospection

Archaeological Prospection, EarlyView.
ABSTRACT Underwater cultural heritage 3D prospection techniques, especially for remains that are partly buried in the ground, are only very rarely available and often can only be applied with considerable technical effort. To overcome this limitation, we evaluate a methodological adaption of widely used and available single channel parametric sediment ...

Risk‐aware safe reinforcement learning for control of stochastic linear systems

Asian Journal of Control, EarlyView.
Abstract This paper presents a risk‐aware safe reinforcement learning (RL) control design for stochastic discrete‐time linear systems. Rather than using a safety certifier to myopically intervene with the RL controller, a risk‐informed safe controller is also learned besides the RL controller, and the RL and safe controllers are combined together ...

A Modified Arthroscopic Trans‐Septal Approach via the Figure‐to‐4 Position of the Knee

Arthroscopy Techniques, EarlyView.
Abstract Standard anterior and posterior portals offer limited access to pathologies in the posterior compartment of the knee. The trans‐septal portal facilitates comprehensive visualization and instrumentation in the posterolateral and posteromedial compartments.

The Hybrid Reversible Suture‐Gripping Technique: A Modified Approach for Continuous Meniscal Suturing

Arthroscopy Techniques, EarlyView.
Abstract The suture‐gripping technique (SGT), which uses a suture shuttle, enables unrestricted gripping, accurate needle insertion from inside the joint, and flexible withdrawal of the suture from outside the joint. We considered the possibility of using a continuous suturing technique with this method, and thus, we describe a modified approach, the ...

Less‐Invasive Capsulotomy Strategy in Hip Arthroscopy: The Gluteus Minimus Sign as a Visual Landmark for the Joint Capsule Based on Cadaveric Analysis

Arthroscopy Techniques, EarlyView.
Abstract Hip arthroscopy requires a capsulotomy to achieve adequate visualization and access; however, an excessive incision can increase the risk of postoperative instability. This technical note describes a less‐invasive capsulotomy technique guided by the “gluteus minimus sign,” a fibrous membrane connecting the main tendon of the gluteus minimus to

L‐Capsulotomy and Anatomic Repair of Zona Orbicularis: Hip Arthroscopy Capsular Management for Femoroacetabular Impingement Syndrome

Arthroscopy Techniques, EarlyView.
Abstract As an increasingly recognized technique, the longitudinal outside‐in capsulotomy (LOIC) has the advantages of reducing damage to the iliofemoral ligament and decreasing the impact on hip joint stability. However, it has limitations in exposing and addressing acetabular‐sided lesions, particularly in femoroacetabular impingement syndrome cases ...
