Two-Dimensional Interleaving Schemes with Repetitions [PDF]
, 1997 We present 2-dimensional interleaving schemes, with repetition, for correcting 2- dimensional bursts (or clusters) of errors, where a cluster of errors is characterized by its area. A recent application of correction of 2-dimensional clusters appeared in

Cerebral Blood Transit in Sickle Cell Anemia
Journal of Magnetic Resonance Imaging, EarlyView.ABSTRACT Background Sickle cell anemia (SCA) patients upregulate cerebral blood flow to compensate for decreased arterial oxygen content. Such hyperemic conditions can manifest as venous hyperintense signal on arterial spin labeling (ASL) MRI, which may reflect faster capillary blood transit, altered oxygen extraction fraction (OEF), and infarct risk ...

Performance of Galileo's concatenated codes with nonideal interleaving
, 1988 The Galileo spacecraft employs concatenated coding schemes with Reed-Solomon interleaving depth 2. The bit error rate (BER) performance of Galileo's concatenated codes, assuming different interleaving depths (including infinite interleaving depth) are ...

Journal of Magnetic Resonance Imaging, EarlyView.ABSTRACT Background The performance of 5D imaging in CHD has been previously demonstrated using ferumoxytol rather than gadolinium. Purpose To evaluate the performance of gadolinium enhanced 5D MRI relative to 2D and 3D MRI in CHD patients. Study Type Retrospective.

Interleaving to distinguish relational categories
, 2015 Students are often expected to learn about abstract concepts from both definitions and examples. Recent research suggests that consecutive presentation of examples from the same category (called ???blocking???) may not be the most effective order to ...

Approaches to Computed Tomography Education for Radiography Students
Journal of Medical Radiation Sciences, EarlyView.The aim of this narrative review was to explore the current published literature relating to CT teaching methods and assessment of diagnostic radiography students during university training. Existing CT education evaluations focus on student satisfaction and usability of tools, with post‐lesson knowledge gains reported. Future work should shift towards

Performance evaluation of interleaving techniques for IEEE 802.15.4 transmissions
, 2014 In the wireless sensor network, the WLAN interference, multi-path fading andattenuation are the main reason for packets’ corruption. Forward errorcorrection is one of the methods for error mitigation.

Optical Skyrmions with Tunable or Reconfigurable Topology Using Spin‐Decoupled Metaoptics
Laser &Photonics Reviews, EarlyView.The work introduces advanced optical elements capable of generating and dynamically reconfiguring complex light patterns known as optical skyrmions. By precisely shaping light polarization at the nanoscale, a single engineered metasurface can generate and manipulate robust and tunable polarization textures in an efficient and scalable way.

Students struggle to understand many concepts in statistics such as when to use the appropriate inferential statistic to run a statistical analysis. This study was the first of its kind to incorporate interleaved practice, a form of distributed practice, into a Statistics in Psychology course to see if this educational intervention can help students ...
