Problem 1. Suppose you have seven dice—each a different color of the rainbow; otherwise the dice are standard, with faces numbered 1 to 6. A roll is a sequence specifying a value for each die in rainbow (ROYGBIV) order. For example, one roll is .3; 1; 6; 1; 4; 5; 2/ indicating that the red die showed a 3, the orange die showed 1, the yellow 6,. . . . For the problems below, describe a bijection...

Senna spectabilis (DC.) H.S. Irwin & Barneby (Fabaceae; Caesalpinioideae), commonly known as "canafístula" or "cassia", is widely used in the semi-arid region of northeastern Brazil as a source of forage and timber. The plant presents a high nutritional content in comparison with other forage species that are native to the Brazilian Caatinga; thus, it represents a valuable resource during perio...

In order to achieve the classification of mitral regurgitation, a deep learning network VDS-UNET was designed automatically segment critical regions echocardiography with three sections apical two-chamber, three-chamber, and four-chamber. First, an expert-labeled dataset 153 echocardiographic videos 2183 images from 49 subjects constructed. Then, convolution layer in VGG16 used replace contract...

Purpose. To achieve rapid automated delineation of gross target volume (GTV) and to quantify changes in volume/position of the target for radiotherapy planning using four-dimensional (4D) CT. Methods and Materials. Novel morphological processing and successive localization (MPSL) algorithms were designed and implemented for achieving autosegmentation. Contours automatically generated using MPSL...

In the present work, a series of new 5-substituted-3-(4-arylimino)-1-[5-mercapto(1,3,4-oxadiazolyl)]-methyl-indol-2-one (4a-g) have been synthesized by heterocyclization of 5-substituted-3-(4-arylimino)-2-oxo-1-indole acetylhyrazide (3a-g) on treatment with CS2 in ethanolic KOH. The compound 4a was characterized by its elemental analysis, IR, 1HNMR and Mass Spectroscopy. The synthesized compoun...

The genus Lolium is one of the most important groupings of temperate forage grasses, including about eight recognized species that are native to some temperate and subtropical regions of the northern hemisphere. We examined genetic relationships among 18 accessions representing all Lolium species using RAPD markers. Among 50 random primers that we screened, 13 gave reproducible amplification ba...

This paper computationalizes two linguistic concepts, contrast and focus, for the extraction of pragmatic and semantic salience from spontaneous speech. Contrast and focus have been widely investigated in modern linguistics, as categories that link intonation and information/discourse structure. This paper demonstrates the automatic tagging of contrast and focus for the purpose of robust sponta...

In this paper we introduce and study three new measures for efficient discriminative comparison of phylogenetic trees. The NNI navigation dissimilarity dnav counts the steps along a “combing” of the Nearest Neighbor Interchange (NNI) graph of binary hierarchies, providing an efficient approximation to the (NP-hard) NNI distance in terms of “edit length”. At the same time, a closed form formula ...
