OBJECTIVE Extracardiac pericardial-flap lateral tunnel Fontan operation has the theoretical advantage of growth potentiality of the extracardiac tunnels. The mid-term results of this technique and morphologic change of the lateral tunnel were studied. METHODS Clinical data were reviewed in 42 patients who underwent extracardiac pericardial-flap lateral tunnel Fontan operation between November...

O ne of the least understood aspects of protein synthesis is communication between the ribosome and the nascent peptide. Chiba et al. (1) in this issue of PNAS reveal that, at least in some cases, these dialogues can be species-specific. The ribosome assembles amino acids into proteins in the peptidyl transferase center (PTC) located at the interface side of the large ribosomal subunit. On its ...

Video Model Deformation (VMD) and Projection Moiré Interferometry (PMI) were used to acquire wind tunnel model deformation measurements of the Northrop Grumman-built Smart Wing tested in the NASA Langley Transonic Dynamics Tunnel. The F18-E/F planform Smart Wing was outfitted with embedded shape memory alloys to actuate a seamless trailing edge aileron and flap, and an embedded torque tube to g...

In this paper, wind tunnel results of a real time optimization of a morphing wing in wind tunnel for delaying the transition towards the trailing edge are presented. A morphing rectangular finite aspect ratio wing, having a wind tunnel experimental airfoil reference cross-section, was considered with its upper surface made of a flexible composite material and instrumented with Kulite pressure s...

Purpose The purpose of this study was to compare the geometry and position of the femoral tunnel between the anteromedial portal (AMP) and outside-in (OI) techniques after anatomic single-bundle anterior cruciate ligament (ACL) reconstruction. Materials and Methods We evaluated 82 patients undergoing single-bundle ACL reconstruction with hamstring autografts using either the AMP (n=40) or OI ...

The 15 m long main dipoles for the Large Hadron Collider have now been installed in their final positions in the accelerator tunnel. Geometric measurements of the magnets after many of the production steps from industry to the cryostating, after cold tests and after preparation of the magnets for installation, have been made, permitting careful control of the shape of the magnet, the positionin...

Industry 4.0 calls for validated simulations for rapid customization and through-life designs. Wind tunnel experiments are widely used in validating flow-field simulations for aircraft design and manufacture. In this paper, we develop testing for simulating the NACA0015 model wings in various shapes and Angles of Attacks (AoA) through an anatomy wind tunnel. Particle traces are recorded during ...

For enhancing low lumination image of underground mine tunnel, a hybrid local histogram equalization with partial differential equation is proposed to combine a local histogram equalization and total variation method with edge-stopping function via partial differential equation. The local histogram equalization is to enhance contrast of image with keeping shape and edge, while total variation m...

This paper presents a novel design of a Jiegged “spider” robot capable of moving in a wide range of two-dimensional tunnels. The spider moves in a quasistatic manner, by stably bracing itself against the tunnel walls and moving a free limb to a new position. The design has been strongly influenced by the recent immobilization theory of Rimon and Burdick [13, 15]. The theory dictates the minimum...
