Junction Labyrinthus
Junction Labyrinthus, a 484-km labyrinth terrain of intersecting valleys on Titan at 47.7S, 215.3W, IAU-named in 2017 after a Dune-series planet; a closed valley-rich, karst-like organic plateau and potential cave site.
Junction temperature
Junction temperature is the temperature of the active region of a semiconductor laser, LED, or power device, which sets its threshold, wavelength, efficiency, and lifetime, and always runs above the case or heatsink temperature.
Junction temperature estimation
Junction temperature estimation is the set of electrical, optical, and model-based methods for determining a semiconductor junction's temperature inside a packaged device, used for reliability testing and thermal management.
Junction tree algorithm
The junction tree algorithm is an exact inference method for probabilistic graphical models that computes marginals by message passing on a tree of variable clusters, introduced by Lauritzen and Spiegelhalter in 1988.
Junction Tree VAE
The Junction Tree Variational Autoencoder (JT-VAE or JTVAE) is a generative model introduced at MIT in 2018 that produces chemically valid molecules by first generating a scaffold of substructures, then assembling them.
Junction working (manual telephony)
Junction working was the method by which manually operated telephone exchanges were interconnected: a call was extended over a dedicated junction circuit and completed by operators at the distant board.
Junctional adhesion molecule A
Junctional adhesion molecule A (JAM-A, F11R, CD321), an immunoglobulin superfamily tight-junction protein on endothelium, epithelium, platelets, and leukocytes; mediates stimulus-specific neutrophil transmigration with PECAM-1 and links to thrombosis and cancer.
Junctional cadherin 5-associated protein
JCAD (KIAA1462), junctional cadherin 5-associated protein, is a 1,359-amino-acid human endothelial junction protein at 10p11.23, a GWAS coronary artery disease locus, regulating Hippo/YAP, PI3K/Akt, and MAPK/ERK signaling.
Junctional epidermolysis bullosa (medicine)
Junctional epidermolysis bullosa (JEB), formerly Herlitz and non-Herlitz types, is an autosomal recessive blistering disease with skin separation in the lamina lucida, caused by LAMA3, LAMB3, LAMC2, or COL17A1 mutations; severe JEB is often fatal in infancy.
Junctional epidermolysis bullosa with pyloric atresia
Junctional epidermolysis bullosa with pyloric atresia (JEB-PA) is a severe inherited skin fragility disease combining generalized blistering from birth with congenital blockage of the pylorus, the stomach's outlet.
Junctional rhythm
Junctional rhythm: an arrhythmia arising from the AV node or His bundle instead of the SA node, classified by rate (bradycardia 100 bpm), with absent or retrograde P waves and narrow QRS on ECG.
Junctional sarcoplasmic reticulum protein 1
JSRP1 (JP-45), junctional sarcoplasmic reticulum protein 1, UniProt Q96MG2, is a 331-aa skeletal muscle SR junctional-face membrane protein regulating excitation-contraction coupling via Cav1.1, beta1a, and calsequestrin interactions.
Junctionless transistor
A junctionless transistor is a field-effect transistor with no p-n junction; the first working device was a silicon nanowire built at the Tyndall National Institute in 2010.
Junctophilin
Junctophilins (JPH1-JPH4, junctophilin family) are membrane-tethering proteins bridging plasma membrane and ER/SR in excitable cells, forming triads, dyads, and subsurface cisterns; JPH2 mutations cause cardiomyopathy, JPH3 expansions cause Huntington Disease-Like 2.
Juncus
Juncus is a genus of herbaceous flowering plants in the rush family, commonly known as rushes, with about 350 species distributed almost worldwide, primarily in temperate regions.
Juncus effusus
Juncus effusus, soft rush or common rush, a tufted Juncaceae wetland perennial to 120 cm with leafless stems and side-appearing inflorescences; widespread, weedy in grasslands, used for mats, restoration, and phytoremediation.
Jund
The jund (الجند, plural ajnad) was a military-administrative district of Bilad al-Sham, organized between 628 and 636 and forming the Umayyad caliphate's standing army in Syria.
Jund of al-Andalus
The jund of al-Andalus was the army of Syrian Arab soldiers, settled by tribal district across Muslim Spain in the mid-eighth century as soldiers and tax collectors.
Jundab ibn Abdallah al-Bajali
Jundab ibn Abdallah al-Bajali (جندب بن عبد الله البجلي) was a companion of the Prophet Muhammad of the Bajila tribe who transmitted hadith in Bukhari and Muslim.
Jundiaí
