People experience various lights in daily life, such as sunlight through leaves and candle light. However, digital contents shown in common LCDs cannot express these impressive lights. In this paper, we propose a novel display technique, AugmentedBacklight, which can express impressive lights in the real world by expanding the LCD backlight. The system mainly consists of a transparent LCD, a sc...

The hierarchy of separation axioms that is familiar from topological spaces generalizes to spaces with an isotone and expansive closure function. Neither additivity nor idempotence of the closure function must be assumed.

In this paper, characterizations of the degree to which a mapping $mathcal{T} : L^{X}longrightarrow M$ is an $(L, M)$-fuzzy topology are studied in detail.What is more, the degree to which an $L$-subset is an $L$-open set with respect to $mathcal{T}$ is introduced.Based on that, the degrees to which a mapping $f: Xlongrightarrow Y$ is continuous,open, closed or a quotient mapping with respect t...

The purpose of this exploratory survey study was to determine the perspectives of patients and family visitors about the reasons for and nature of patient- and family-initiated call lights, call light use, and response time to call lights. Fifty-three percent of participants (n = 63) perceived most of their call lights mattered to their safety. Participants believed answering call lights should...

We used a before-after-control-impact paired design to examine the effects of a switch from low-pressure sodium (LPS) to light emitting diode (LED) street lights on bat activity at twelve sites across southern England. LED lights produce broad spectrum 'white' light compared to LPS street lights that emit narrow spectrum, orange light. These spectral differences could influence the abundance of...
