The lack of sensors for low cost, extensive, and continuous detection of vapor pollutants is a serious concern for health and safety in industrialized urban areas. Colorimetric sensors, such as distributed Bragg reflectors made of polymers, could achieve this task thanks to their low cost and easy signal transduction but are typically affected by low vapor permeability and lack of selectivity w...
The cover picture shows a split RNA reporter strategy for detecting target mRNA in mammalian cells. A tetrahymena group I intron ribozyme reporter is split into two halves, each of which carries a part of the coding sequence of the reporter mRNA, a fragment of the ribozyme, and an antisense sequence complementary to a target mRNA. Both halves bind with the target mRNA and are assembled into an ...
In the present work we model a Multiquantum Well structure Separate Absorption and Charge Multiplication Avalanche Photodiode (MQW-SACM-APD), while the Absorption region coincide with the MQW. We consider the nonuniformity of electric field using split-step method in active region. This model is based on the carrier rate equations in the different regions of the device. Using the model we obtai...
The existing solutions for reducing total harmonic distortion (THD) using different control algorithms in shunt active power filters (SAPFs) are complex. This work proposes a split source inverter (SSI)-based SAPF improving the quality nonlinear load system. advantage of SSI topology is that it single stage boost with an inductor and capacitor where conventional two stages intermediate DC-DC co...
The manifested dominance split-brain monkeys usually show for performing visual tasks through one hemisphere, when perceptual information is equally available to both, was analyzed. Three split-brain monkeys, each being trained similar yet different discriminations to each hemisphere, were allowed the opportunity to choose between the two problems when both were presented simultaneously. Initia...
JOHNSON, J. D. AND M. S. GAZZANIGA. Reversal behavior in split-brain monkeys. PHYSIOL. BEHAV. 6 (6) 707--709, 1971.Using split-brain monkeys, reversal behavior was observed under two conditions. In the first both hemispheres viewed the discrimination cues. Previous to this one hemisphere had been taught to respond to one cue and the other hemisphere had learned the opposite response. The task w...
