Tagging physical objects to get a link from the physical world into some kind of technology has been done for a long time. The most commonly known is probably the barcodes that is used in five billion scans every day. During a project at Xerox Research Centre Europe in Cambridge, we came across the concept of Glow Tags. It is partly an expansion of the more traditional tags by, from a user pers...

1. In firefly larvae, extracellular recordings from the light organ nerve show that a volley of action potentials elicits a glow of an intact animal. 2. Intracellular recordings from the photocytes show that they respond to nerve stimulation with a slow, graded depolarization which precedes light emission. The depolarization begins about 0-5 s after the nerve is stimulated; it peaks about 1 s a...

In order to understand the details of high-field breakdown in microstructures that are vacuum packaged, a series of experiments are used to determine characteristics of microdischarges. The results support a reinterpretation of conventional assumptions based upon large scale discharges. When planar microelectrodes are used, Paschen’s curve is not applicable in the traditional sense: the breakdo...

1. Pelagia noctiluca responds to galvanic stimulation by a luminescent glow at the anode. If placed near the cathode a secondary glow occurs also on the cathodal side. 2. The luminescent slime of Pelagia when subjected to the galvanic current glows around the cathode. This is referred partly to the movement of hydrogen bubbles, but in the main to the alkali formed at the cathode. 3. The cause o...

The low pressure glow discharges considered in this paper are the hollow cathode (Paschen), and the flat cathode (Grimm). Both discharges have similar voltage—current characteristics which are responsible for their radiation stability. The analytical sample is supplied to the discharge through a sputtering mechanism which provides a stable and non-selective source of particles. Some of the fund...

In the thermoluminescence (TL) glow curve of photosystem II, particles depleted of manganese, a tyrosine modifier, 7-chloro-4-nitrobenz-2-oxa-1,3-diazole (NBD) abolishes the TL band appearing around -55 degrees C (TL-55). Addition of a histidine modifier, diethylpyrocarbonate results in the disappearance of the band peaking around -30 degrees C (TL-30). NBD treatment also abolishes the EPR sign...

We show that our recent SU(4) generalized “rishon” composite model for quarks and leptons, augmented either by the hypothesis of breaking of color SU(3) to “glow” SO(3), or by the hypothesis of incomplete color neutralization in very hard processes, leads to an interpretation of the HERA positron-jet events as the production by color gluon exchange, followed by the decay by color gluon emission...

Experimental work in economics prompted the development of theories of other-regarding behavior. In this paper we reanalyze two classic public goods experiments and focus on the nature individuals’ responses to others’ behavior in order to help distinguish alternative motives of giving, including altruism, warm glow, reciprocity and inequality aversion. Analysis that allows for asymmetric feedb...

2014 Spatially resolved spectroscopic diagnostics such as plasma-induced emission, laser-induced fluorescence and laser optogalvanic spectroscopy are used to characterize the cathode sheath and the negative glow of an abnormal glow dc discharge in nitrogen. These diagnostics provide local information on the excitation and ionization functions, on the concentrations of ions and on the rotational...

In general terms, lighting research has been focused in the development of artificial light with the purpose of saving energy and having more durable lamps. However, the consequences that artificial night lighting could bring to the human being and living organisms have become an important issue recently. Light pollution represents a significant problem to both the environment and human health ...
