The retina is a highly metabolic tissue equipped with an exquisite autoregulatory mechanism. Extending the assessment of retinal function to feasibly measure autoregulatory responses in this vital tissue would advance knowledge regarding the diagnosis, pathophysiology, and treatment of many ophthalmic diseases. Pechauer et al. derived retinal angiograms without the need for intravenous dye by a...

To exploit instruction level parallelism in programs over multiple basic blocks, programs should have reducible control flow graphs. However not all programs satisfy this property. A new method, called Controlled Node Splitting (CNS), for transforming irreducible control flow graphs to reducible control flow graphs is presented. CNS duplicates nodes of the control flow graph to obtain reducible...

We used optical coherence tomography (OCT) angiography with a high-speed swept-source OCT system to investigate retinal blood flow changes induced by visual stimulation with a reversing checkerboard pattern. The split-spectrum amplitude-decorrelation angiography (SSADA) algorithm was used to quantify blood flow as measured with parafoveal flow index (PFI), which is proportional to the density o...

We probe the secondary rheology of granular media, by imposing a main flow and immersing a vane-shaped probe into the slowly flowing granulate. The secondary rheology is then the relation between the exerted torque T and rotation rate ω of our probe. In the absence of any main flow, the probe experiences a clear yield-stress, whereas for any finite flow rate, the yield stress disappears and the...

Hybrid CAA-approaches are commonly used for aeroacoustic engineering applications. In this kind of computational techniques, the numerical domain is split into a noise generating region, where an aerodynamic field generates the acoustic sources, and an acoustic propagation region. Nowadays a large variety of hybrid approaches exist differing from each other in the way the source region is model...

This paper aims to accurately realize given traffic split ratios in switches with small performance degradation. For given traffic split ratios calculated mathematically by TE algorithms in the control plane, the load distribution mechanisms in the data plane implement such splits without breaking flows. Treating all flows equally, the state-of-the-art approaches deployed in switches do not pro...

OBJECTIVE Currently, no quantitative guidelines have been established for treatment of left pulmonary artery (LPA) stenosis. This study aims to quantify the effects of LPA stenosis on postoperative hemodynamics for single-ventricle patients undergoing stage II superior cavopulmonary connection (SCPC) surgery, using a multiscale computational approach. METHODS Image data from 6 patients were s...

Introduction Le Fort I and sagittal split ramus osteotomies are the most commonly performed orthognathic surgery procedures on the maxilla and mandible, respectively. Techniques Despite progress in the techniques, these procedures may still be associated with morbidity, expressed as inflammation, inadequate bony union, periodontal damages or in extreme cases even total bone loss. Discussion...

I show that the self-consistent solution of the problem of MHD plasma flow in the magnetosphere of an oblique rotator with an initially split-monopole magnetic field is reduced to the solution of a similar problem for the axisymmetric rotator. All properties of the MHD cold plasma flows from the axisymmetric rotators with the initial split-monopole magnetic field are valid for the oblique rotat...

OBJECTIVES During the first 48 hours after placement, an autograft "drinks" nutrients and dissolved oxygen from fluid exuding from the underlying recipient bed ("plasmatic imbibition"). The theory of inosculation (that skin grafts subsequently obtain nourishment via blood vessel "anastomosis" between new vessels invading from the wound bed and existing graft vessels) was hotly debated from the ...
