Ten Citrus (Linnaeus, 1753) species of North-East India have been karyo-morphologically analysed. All studied species had 2n=18 chromosomes without any evidence of numerical variation. All the chromosomes were found to be of metacentric and sub-metacentric in all the species; the morphology of the chromosomes showing size difference only. Symmetrical karyotype which does not have much differenc...

A high-speed sorter was used to remove kernels infected with Karnal bunt from 1800g wheat samples. When the sorter removed about 8% or more of the sample, the reject portion contained 100% of the bunted kernels. Concentrating the bunted kernels in a smaller sample size will reduce sample inspection time and should reduce inspection errors. One high-speed sorter can process up to 8800 kg/hr, thu...

We present measurements and simulation of fluid flow and sphere motion in a pressure-driven microfluidic sorter designed for Drosophila embryos. We simulate the flow fields for different channel layouts and study the effect of control pressure, chamber length and entrance length on switching time to find geometries and conditions for optimized embryo movement. We validate the sorter design with...

Hardware sorters exploit inherent concurrency to improve the performance of sequential, softwarebased sorting algorithms. They are often based on Batcher’s odd-even or bitonic merging networks to attenuate the areagreedy hardware solutions. In this paper, a new hardware sorter architecture is presented. It is composed of smaller sorter circuits inspired on insertion sorting algorithms that cont...

Beginning in 1993, Florida’s citrus industry has been invaded by citrus leafminer (Phyllocnistis citrella Stainton, Lepidoptera: Gracillariidae), brown citrus aphid (Toxoptera citricida Kirkaldy, Homoptera: Aphididae), and the Asian citrus psylla (Diaphorina citri Kuwayama, Homoptera: Psyllidae). The source(s) of these pests remain unknown but other countries in the Caribbean, as well as Centra...

AIMS The Asian citrus psyllid (ACP), Diaphorina citri Kuwayama transmits the bacterium 'Candidatus Liberibacter asiaticus' (Las), which causes citrus huanglongbing (HLB) disease. Although many studies have been conducted on the biology of ACP on different host plants, few have taken the plant, Las bacteria and the vector insect within one context to evaluate the effects of Las on the fitness of...

A convolutional neural network is used to align an orbital angular momentum sorter in a transmission electron microscope. The method demonstrated using simulations and experiments. As result of its accuracy speed, it offers the possibility real-time tuning other optical devices beam shaping configurations.

Citrus canker, a bacterial disease of citrus tree leaves, causes significant damage to citrus production worldwide. Effective and fast disease detection methods must be undertaken to minimize the losses of citrus canker infection. In this paper, we present a new approach based on global features and zonebased local features to detect citrus canker from leaf images collected in field which is mo...

A new early season method of creating high detail citrus yield maps in a grove was evaluated. A monochromatic near-infrared camera was equipped with interchangeable optical band pass filters was used to capture images of citrus fruit in a Florida citrus grove during the late Fall of 2006 growing season. Over 500 images were acquired of 36 separate on tree citrus fruit targets using three differ...

The invasive Asian citrus psyllid (Diaphorina citri Kuwayama) is the vector of the bacterial pathogen (‘Candidatus Liberibacter asiaticus’) that is the putative causal agent of citrus greening disease (Huanglongbing disease) in citrus in many areas of the world. The capacity to predict the potential geographic distribution, phenology and relative abundance of the pest and disease is pivotal to ...
