Landau-Kleffner Syndrome (LKS) is an uncommon condition in which a child between the ages of 3 to 9 years loses the ability to speak and understand speech. These children may also have autistic-like behavior. This condition is accompanied by an abnormal EEG with epileptiform discharges generally in the dominant hemisphere in the speech areas of the brain. LKS usually evolves into electrical status epilepticus during sleep (ESES) characterized by continuous spike and wave activity in the majority of non-rapid eye movement (non-REM) sleep. The outcome of this syndrome varies according to the onset of the disease. The epileptic aspect of Landau-Kleffner Syndrome is treated with antiepileptic medication and sometimes surgery; and the speech disability is treated with intensive language therapy. The success of each treatment is dependent on the age and advancement of the disease and varies with each patient. © ASET, Missouri. Source

Mesa Technology | Date: 2015-10-04

A light-emitting diode (LED) includes a first type semiconductor layer, a second type semiconductor layer, a first current controlling structure, and a first electrode. The second type semiconductor layer is joined with the first type semiconductor layer. The second type semiconductor layer has a first region and a second region, in which the first region has a first threading dislocation density, the second region has a second threading dislocation density, and the first threading dislocation density is greater than the second threading dislocation density. The first current controlling structure is joined with the first type semiconductor layer and has at least one first current-injecting zone therein, in which the vertical projection of the second region on the first current controlling structure at least partially overlaps with the first current-injecting zone. The first electrode is electrically coupled with the first type semiconductor layer.

A light-emitting diode (LED) lighting device includes a substrate, a first bottom electrode, a bottom transparent isolation layer, a first vertical LED, a second vertical LED, a first top transparent electrode, and a second top transparent electrode. The first bottom electrode is disposed on the substrate and is reflective. The first vertical LED and the second vertical LED are disposed on the first bottom electrode. The bottom transparent isolation layer covers the substrate and the first bottom electrode and exposes the first vertical LED and the second vertical LED. The first top transparent electrode is electrically connected to the first vertical LED. The second top transparent electrode is electrically connected to the second vertical LED. The first top transparent electrode, the second top transparent electrode, and the first bottom electrode cooperate to electrically connect the first vertical LED and the second vertical LED in series.
