We recently introduced fluorescent false neurotransmitters (FFNs) as optical tracers that enable the visualization of neurotransmitter release at individual presynaptic terminals. Here, we describe a pH-responsive FFN probe, FFN102, which as a polar dopamine transporter substrate selectively labels dopamine cell bodies and dendrites in ventral midbrain and dopaminergic synaptic terminals in dor...

Most of the prior work in biometric literature has only emphasized on the issue of feature extraction and classification. However, the critical issue of examining the usefulness of extracted biometric features has been largely ignored. Feature evaluation/selection helps to identify and remove much of the irrelevant and redundant features. The small dimension of feature set reduces the hypothesi...

Training very deep networks is an important open problem in machine learning. One of many difficulties is that the norm of the back-propagated error gradient can grow or decay exponentially. Here we show that training very deep feed-forward networks (FFNs) is not as difficult as previously thought. Unlike when backpropagation is applied to a recurrent network, application to an FFN amounts to m...

In this paper, the Artificial Neural Network (ANN) approach is applied for forecasting groundwater level fluctuation in Aghili plain,southwest Iran. An optimal design is completed for the two hidden layers with four different algorithms: gradient descent withmomentum (GDM), levenberg marquardt (LM), resilient back propagation (RP), and scaled conjugate gradient (SCG). Rain,evaporation, relative...

With increasing global reliance on the Internet as a medium to transmit information comes an increased risk of cyber-attack. Social networking sites are the most popular tools in internet for social interaction between the people. Online social networks (OSNs) have rapidly become a prominent and widely used service, offering a wealth of personal and sensitive information with significant securi...

within 21 days. The likelihood ratio for a negative result [(1 sensitivity)/specificity] was 0.59 for birth within 7 days, 0.68 for birth within 14 days, and 0.53 for birth within 21 days. The data in Table 1 are similar to those obtained in previous studies using the ELISA-based assay. Joffe et al. (1 ) reported a NPV of 99.6% and a PPV of 9.1% for 243 patients who delivered within 7 days with...

RESUMO O objetivo do presente estudo foi comparar in vitro o efeito da aplicação tópica de flúor na forma de gel acidulado (FFA) ou neutro (FFN) com um dentifrício fluoretado (MFP), na incorporação e ação anticariogênica do flúor. Foram utilizados 125 blocos obtidos de esmalte humano, divididos em 5 grupos de acordo com o tratamento e submetidos à ciclagem de pH durante dez dias. Analisou-se o ...

High usage of antibiotics has led to an increase in bacteria developing antibiotic resistance. A resistant strain human pathogenic been found the non-curative for animal production. Moringa oleifera and Azardiracta indica are phytobiotics which have proven be natural, with no residual effect thought ideal An experiment was conducted determine growth performance gut health broilers fed neem as a...

DEtection TRansformer (DETR) is a recently proposed method that streamlines the detection pipeline and achieves competitive results against two-stage detectors such as Faster-RCNN. The DETR models get rid of complex anchor generation post-processing procedures thereby making more intuitive. However, numerous redundant parameters in transformers make computation storage intensive, which seriousl...
