It is often desirable or unavoidable to display Virtual Reality (VR) stereoscopic content at low brightness. For example, a dimmer reduces the flicker artefacts that are introduced by low-persistence VR headsets. also saves power, prolongs battery life, and cost of projection system. Additionally, stereo movies usually displayed relatively luminance due polarization filters other optical elemen...

Does bright lighting seem more desirable when people feel hopeless? Common parlance such as ‘‘ray of hope’’ depicts an association between hope and the perception of brightness. Building on research in embodied cognition and conceptual metaphor, we examined whether incidental emotion of hopelessness can affect brightness perception, which may influence people’s preference for lighting. Across f...

A model for gas outflows is proposed which simultaneously explains the correlations between the (i) equivalent width of low ionization and Lyα lines, (ii) outflow velocity, and (iii) star formation rate observed in Lyman Break Galaxies (LBGs). Our interpretation implies that LBGs host short-lived (30 ± 5 Myr) starburst episodes observed at different evolutionary phases. Initially, the starburst...

Infectious bronchitis (IB) is an acute and contagious disease of poultry. The spike glycoprotein (S) of IB virus is a dimmer and is cleaved into two glycopolypeptides, S1 and S2 post-translationally. S1 gene defines the serotype and plays a major role in induction of protective immunity. Eukaryotic expression systems are frequently employed for the production of recombinant S1 proteins as it is...

The coalescence of a binary neutron star pair is expected to produce gravitational waves (GW) and electromagnetic radiation, both of which may be detectable with currently available instruments. We describe a search for a predicted r-process optical transient from these mergers, dubbed the “kilonova” (KN), using griz broadband data from the Dark Energy Survey Supernova Program (DES-SN). Some mo...

We calibrate the photographic photometry of the revised New Luyten TwoTenths catalog (rNLTT) by matching 3448 rNLTT stars to the Sloan Digital Sky Survey (SDSS). The correction is linear in magnitude and goes from zero at V ∼ 14 to 0.32 mag at V = 19, in the sense that rNLTT was previously too bright. The correction implies that the underlying USNO-A2.0 photometry, on which rNLTT photometry is ...

Metal-free organic phosphorescent materials are attractive alternatives to the predominantly used organometallic phosphors but are generally dimmer and are relatively rare, as, without heavy-metal atoms, spin-orbit coupling is less efficient and phosphorescence usually cannot compete with radiationless relaxation processes. Here we present a general design rule and a method to effectively reduc...

The science universe is dimmer after one of our brightest stars, Susan Lee Lindquist, was taken by cancer on October 27, 2016. Sue was an innovative, creative, out-of-the-box scientific thinker. She had unique biological intuition-an instinct for both the way things worked and the right questions to ask to uncover new research insights. Her wide-ranging career began with the study of protein fo...
