Hace 4 días · The Fresnel equations (or Fresnel coefficients) describe the reflection and transmission of light (or electromagnetic radiation in general) when incident on an interface between different optical media.
Hace 3 días · In a wireless power transmission system, an electrically powered transmitter device generates a time-varying electromagnetic field that transmits power across space to a receiver device; the receiver device extracts power from the field and supplies it to an electrical load.
Hace 7 horas · Attenuation in fiber optics, also known as transmission loss, is the reduction in intensity of the light beam (or signal) with respect to distance travelled through a transmission medium. Attenuation coefficients in fiber optics usually use units of dB/km through the medium due to the relatively high quality of transparency of modern optical transmission.
Hace 3 días · Here the authors describe an intranasal vaccine that protects against multiple strains of SARS-CoV-2 and SARS-CoV while preventing transmission to vaccine naïve hamsters. Immunized monkeys elicit ...
Hace 1 día · 1. Machine learning and neighborhood slot allocation-enabled transmission for IoT networks with minimum possible communication overheads. 2. K-mean algorithm is used to ensure maximum possible utilization of the available bandwidth and empty slots in IoT. 3.
Hace 2 días · Background Amyotrophic lateral sclerosis (ALS) is characterized by progressive motor neuron (MN) degeneration, leading to neuromuscular junction (NMJ) dismantling and severe muscle atrophy. The nuclear receptor interaction protein (NRIP) functions as a multifunctional protein. It directly interacts with calmodulin or α-actinin 2, serving as a calcium sensor for muscle contraction and ...
