Detectors have historically been calibrated for spectral power responsivity at the National Institute of Standards and Technology by using a lamp-monochromator system to tune the wavelength of the excitation source. Silicon detectors can be calibrated in the visible spectral region with combined standard uncertainties at the 0.1% level. However, uncertainties increase dramatically when measurin...

OBJECTIVES The purposes of this study were to investigate the responsivity patterns of typical 3- and 4-year-old Israeli children to tactile or vestibular stimulation, or both, and to examine whether differences in these patterns exist between them with respect to age and gender. METHOD The study sample consisted of one hundred seventeen 3-year-old and one hundred forty-three 4-year-old healt...

The responsivity to diffuse radiation of a solar cell based pyranometer is studied. Diffuse measurements are made using a shade disk for a LiCor Pyranometer and an Eppley PSP pyranometer mounted side by side on an automatic tracker. The difference in the diffuse responsivity varies by 30 to 40% between cloudy conditions and clear skies. This difference is attributed to the spectral dependence o...

Abstract Background Treatment-resistant depression (TRD) is a significant problem in clinical practice and reason for the lack of functional recovery among depressed patients. Sleep disturbances poor alertness are common residual symptoms. Main body abstract Many patients with refractory experience symptoms, such as insomnia, daytime sleepiness, alertness. This literature review we searched ele...

We have investigated theoretically the effects of the charging energy to the normal metal–insulator–superconductor (NIS) tunnel junction used as a thermometer. We demonstrate by numerical calculations how the charging effects modify NIS thermometry, and how the voltage–to–temperature response and the responsivity |dV/dT | of a current biased thermometer are affected. In addition, we show that t...

Some infants experience atypical levels of over-responsivity to sensations, which limit their ability to interact and explore their environment. Yet, little is known about typical development of over-responsivity during infancy or whether the presence of extreme over-responsivity in infancy is a predictor of clinically significant sensory over-responsivity (SOR) at school-age. This study follow...

Conservatives are often thought to have a negativity bias – responding more intensely to negative than positive information. Yet, recent research has found that greater endorsement of conservative beliefs follow from both positive and negative emotion inductions. This suggests that the role of affect in political thought may not be restricted to negative valence, and more attention should be gi...

Abstract Individuals with migraine generally experience photophobia and/or phonophobia during and between attacks. Many different mechanisms have been postulated to explain these phenomena including abnormal patterns of connectivity across the cortex. The results, however, remain contradictory there is no clear consensus on nature cortical abnormalities in migraine. Here, we uncover alterations...

Broadband UV measurements are evaluated when UV-A irradiance meters measure optical radiation from 365 nm UV sources. The CIE standardized rectangular-shape UV-A function can be realized only with large spectral mismatch errors. The spectral power-distribution of the 365 nm excitation source is not standardized. Accordingly, the readings made with different types of UV meters, even if they meas...
