Group-III-nitride laser diode (LD)-based solid-state lighting device has been demonstrated to be droop-free compared to light-emitting diodes (LEDs), and highly energy-efficient compared to that of the traditional incandescent and fluorescent white light systems. The YAG:Ce3+ phosphor used in LD-based solid-state lighting, however, is associated with rapid degradation issue. An alter...
Sensory systems must avoid saturation to encode a wide range of stimulus intensities. One way the retina accomplishes this is by using both dim-light-sensing rod and bright-light-sensing cone photoreceptor circuits. OFF cone bipolar cells are a key point in this process, as they receive both excitatory input from cones and inhibitory input from AII amacrine cells via the rod pathway. However, i...
The receptive fields of simple cells in the cat visual cortex are, by definition, divided into ON and OFF subfields. There is little doubt that each subfield is generated by excitatory input from geniculate neurons of the appropriate center type: ON subfields by ON-center cells, and OFF subfields by OFF-center cells. In intracellular records, ON subfields can be detected as regions in which lig...
A system has been established for continuous recording of rectal and body surface temperatures in conscious, chair-restrained rhesus macaques. Diurnal changes in rectal temperature and body surface temperatures of head, back, abdomen, and inner thigh were recorded for 24 hours under conditions of intermittent or constant light. When lights were on for 8 hours (0800 to 1600 hours) and off for 16...
Automatic control of HVAC and artificial lights has been one of the popular methods for achieving energy-efficient buildings. The current systems operate using fixed setpoint controls, which are usually based on a conservative approach. Moreover, the lighting systems require additional sensor deployment to cope up with continuous fluctuation of natural light intensity. In this work, we describe...
The quality of wine can be affected by several factors after bottling: temperature changes, shipment time, type and amount mechanical stress (vibrations) environmental conditions, such as light exposure relative humidity. effects delivery using different packaging systems (boxes, bottles, containers) the impacts mode (car, truck, airplane cargo ship) are reviewed, along with compositional marke...
conclusions the results showed that the heat stress increased by increasing air velocity and humidity in both groups. the air velocity with high humidity can be considered as a positive factor in the occurrence of heat strain. therefore, the incidence of heat stress decreases with the increase of humidity and reduction of air velocity or with increase of air velocity and reduction of humidity i...
