This study proposes a different angle to social network analysis that evaluates patent value and explores its influencing factors using the network centrality and network position. This study utilizes a logistic regression model to explore the relationships in the LED industry between patent value and network centrality as measured from out-degree centrality, in-degree centrality, in-closeness centrality, and network position, which is measured from effect size. The empirical result shows that out-degree centrality and in-degree centrality have significant positive effects on patent value and that effect size has a significant negative effect on patent value.

In this Letter, we report a novel NaLaMgWO:Mn double-perovskite phosphor. Under the excitation at 342 nm, this phosphor showed a high-efficiency far-red emission at approximately 700 nm with interna...
In the past few years, a substantial progress has been made for perovskite light-emitting devices. Both pure green and infrared perovskite light-emitting devices with external quantum efficiency over ...
Sublimable cationic iridium(III) complexes consisting of light-emitting coordinated iridium(III) cations and nonluminous negative counter-ions, show excellent photophysical properties, superior electr...
This study compared light transmission through different thicknesses of bulk-fill resin-based composites (RBCs) using a polywave and a single-peak light-emitting diode light-curing unit (LCU). The eff...
This study investigated light emitting diode (LED) treatment for patients with melasma on darker skin types.
Effects of Phototherapy by Low-level Light-emitting Diode Therapy (LEDT) on Clinical, Biochemical, Biomechanical, Histologic and Genetic Responses of Muscle Performance of Young Males Submitted to Physical Strength Training
Muscle performance is largely influenced by modulations in gene expressions of muscle tissue. In this context, light-emitting diode therapy (LEDT) has been used to improve muscle performan...
The purpose of this study was to determine whether light emitting diode (LED) therapy can improve skin appearance of human subjects with aged/photoaged skin. A reduction in rhytid depth a...
The purpose of the study is to assess the survival of patients treated with Litx™ versus standard of care therapies in the treatment of unresectable hepatocellular carcinoma (HCC), and t...
This is a randomized, controlled clinical trial of negative ion generation or light-emitting photodiode therapy for Seasonal Affective Disorder (SAD, winter depression), for subjects with ...
Skin scarring (fibrosis) is a common complication in the wound healing process and remains a therapeutic challenge. Scar formation often occurs following injury to the skin such as surgery...
A photoprotein isolated from the bioluminescent jellyfish Aequorea. It emits visible light by an intramolecular reaction when a trace amount of calcium ion is added. The light-emitting moiety in the bioluminescence reaction is believed to be 2-amino-3-benzyl-5-(p-hydroxyphenyl)pyrazine (AF-350).
A syndrome of persistent PULMONARY HYPERTENSION in the newborn infant (INFANT, NEWBORN) without demonstrable HEART DISEASES. This neonatal condition can be caused by severe pulmonary vasoconstriction (reactive type), hypertrophy of pulmonary arterial muscle (hypertrophic type), or abnormally developed pulmonary arterioles (hypoplastic type). The newborn patient exhibits CYANOSIS and ACIDOSIS due to the persistence of fetal circulatory pattern of right-to-left shunting of blood through a patent ductus arteriosus (DUCTUS ARTERIOSUS, PATENT) and at times a patent foramen ovale (FORAMEN OVALE, PATENT).
Lasers with a semiconductor diode as the active medium. Diode lasers transform electric energy to light using the same principle as a light-emitting diode (LED), but with internal reflection capability, thus forming a resonator where a stimulated light can reflect back and forth, allowing only a certain wavelength to be emitted. The emission of a given device is determined by the active compound used (e.g., gallium arsenide crystals doped with aluminum or indium). Typical wavelengths are 810, 1,060 and 1,300 nm.

A drug-induced depression of consciousness during which patients respond purposefully to verbal commands, either alone or accompanied by light tactile stimulation. No interventions are required to maintain a patent airway. (From: American Society of Anesthesiologists Practice Guidelines)
A condition in which the FORAMEN OVALE in the ATRIAL SEPTUM fails to close shortly after birth. This results in abnormal communications between the two upper chambers of the heart. An isolated patent ovale foramen without other structural heart defects is usually of no hemodynamic significance.
