Superpixel Convolutional Networks using Bilateral Inceptions

In this paper we propose a CNN architecture for semantic image segmentation. We introduce a new 'bilateral inception' module that can be inserted in existing CNN architectures and performs bilateral filtering, at multiple feature-scales, between superpixels in an image. The feature spaces for bilateral filtering and other parameters of the module are learned end-to-end using standard backpropagation techniques. The bilateral inception module addresses two issues that arise with general CNN segmentation architectures. First, this module propagates information between (super) pixels while respecting image edges, thus using the structured information of the problem for improved results. Second, the layer recovers a full resolution segmentation result from the lower resolution solution of a CNN. In the experiments, we modify several existing CNN architectures by inserting our inception module between the last CNN (1x1 convolution) layers. Empirical results on three different datasets show reliable improvements not only in comparison to the baseline networks, but also in comparison to several dense-pixel prediction techniques such as CRFs, while being competitive in time.Comment: European Conference on Computer Vision (ECCV), 201

The Mare as a Model for Luteinized Unruptured Follicle Syndrome: Intrafollicular Endocrine Milieu.

Luteinized unruptured follicle (LUF) syndrome is a recurrent anovulatory dysfunction that affects up to 23% of women with normal menstrual cycles and up to 73% with endometriosis. Mechanisms underlying the development of LUF syndrome in mares were studied to provide a potential model for human anovulation. The effect of extended increase in circulating LH achieved by administration of recombinant equine LH (reLH) or a short surge of LH and decrease in progesterone induced by prostaglandin F2α (PGF2α) on LUF formation (Experiment 1), identification of an optimal dose of COX-2 inhibitor (flunixin meglumine, FM; to block the effect of prostaglandins) for inducing LUFs (Experiment 2), and evaluation of intrafollicular endocrine milieu in LUFs (Experiment 3) were investigated. In Experiment 1, mares were treated with reLH from Day 7 to Day 15 (Day 0=ovulation), PGF2α on Day 7, or in combination. In Experiment 2, FM at doses of 2.0 or 3.0 mg/kg every 12 h and human chorionic gonadotropin (hCG) (1500 IU) were administered after a follicle ≥32 mm was detected. In Experiment 3, FM at a dose of 2.0 mg/kg every 12 h plus hCG was used to induce LUFs and investigate the intrafollicular endocrine milieu. No LUFs were induced by reLH or PGF2α treatment; however, LUFs were induced in 100% of mares using FM. Intrafollicular PGF2α metabolite, PGF2α, and PGE2 were lower and the ratio of PGE2:PGF2α was higher in the induced LUF group. Higher levels of intrafollicular E2 and total primary sex steroids were observed in the induced LUF group along with a tendency for higher levels of GH, cortisol, and T; however, LH, PRL, VEGF-A, and NO did not differ between groups. In conclusion, this study reveals part of the intrafollicular endocrine milieu and the association of prostaglandins in LUF formation, and indicates that the mare might be an appropriate model for studying the poorly understood LUF syndrome

Contribuição de 10 (dez) assentamentos na economia do município de Unaí – MG.

Esse trabalho tem como objetivo contribuir para a discussão sobre a contribuição que 10 assentamentos de reforma agrária exercem sobre a economia do município de Unaí. Para isso utilizou-se os dados coletados no Diagnóstico Rápido Dialogado (DRD) de 390 sistemas de produção que correspondem a 75% do total dos lotes dos 10 assentamentos. Os resultados obtidos mostraram a importância dos assentamentos para o desenvolvimento do município tanto pela oferta de produtos produzidos pelos no mercado local como pela contribuição das famílias como consumidores no comércio local. O que, em última instância, favorece a maior circulação de recursos e dinamiza a economia impactando positivamente o desenvolvimento do município. Abstract: This project´s goal is to contribute to the discussion on the contribution that 10 agrarian reform settlements have on the economy of the city of Unai. For this we used the data collected in Rapid Diagnostics Dialogued (DRD) of 390 systems of production which correspond to 75% of the total batch of 10 settlements. The results showed the importance of the settlements for the development of the city by both the supply of products produced by the local market as the contribution on households as consumers of the local market. What, ultimately, promotes increased circulation of resources and stimulates the economy positively by impacting the development of the municipality

Improvement of Lucerne Cutting Management: The Relative Impact of Initial Organic Reserves, Cutting Height and Residual Leaf Area on Forage Yield

Less lucerne (Medicago sativa L.) is now grown because of difficulties arising from 2 interacting characteristics: productivity and stand persistence. Optimisation of these two parameters depends highly of the cutting management (cutting height and/or frequency) and of the taproot N reserves. For example, Avice et al. (1997) showed that lucerne shoot regrowth is relates closely to taproot soluble protein concentrations (especially vegetative storage protein: VSP). However, it is not known how stubble C-N reserves and/or residual leaf area (both depending of the cutting management) influence the contribution of taproot reserve-derived C-N supply to regrowing lucerne shoots after defoliation. This study aimed to estimate the role of stubble C/N reserves or residual leaf area (RLA) on the contribution of taproot N reserves to shoot regrowth of lucerne after cutting

Incidence of natural control agents of the velvetbean caterpillar and response of its predators to insecticide treatments in Brazilian soybean fields

Lagartas de Anticarsia gemmatalis Hubner foram coletadas em soja (Glycine max (L.) Merrill) para determinar os níveis populacionais e a porcentagem de infecção pelo fungo-Nomuraea rileyi (Farlow) Samson. Os níveis populacionais de larvas e adultos do predador Colosoma argentatus granulatum (Perty) foram determinados utilizando armadilhas de solo. Foi estudada a relação entre a ressurgência de A. gemmatalis e os níveis populacionais dos predadores C. argentatus granulatum, Geocoris spp. e Nabis spp. sob influência de inseticidas. A infestação pelo fungo N. rileyi começou em fevereiro, durante o estágio de desenvolvimento dos legumes quando a terceira geração de lagartas alcançou o seu pico. Três semanas mais tarde 100% das lagartas observadas sobre as folhas estavam infectadas pelo fungo. A atividade de C argentatus granulatum coincidiu com o pico da terceira geração de A. gemmatalis. As populações de Geocoris spp. e Nabis spp. foram severamente afetadas com as aplicações de monocrotofos e metilparation, mas a aplicação diflubenzuron, um inibidor da formação de quitina, aparentemente não provocou efeito deletério.Larvae of the velvetbean caterpillar Anticarsia gemmatalis Hubner were collected from soybean (Glycine max (L.) Merrill) to determine their population levels and percentage of infection by the fungus, Normuraea rileyi (Farlow) Samson. Seasonal population levels of larvae and adults of the carabid predator, Calosoma argentatus granulatum (Perty) were determined by pitfall trap collections. The relationship between resurgence of Anticarsia and populations of Calosoma, geocorids, and nabids as influenced by insecticides was studied. Fungus attack began in February during the pod development stage when the third generation of Anticarsia larvae were reaching a peak and 100% of larvae observed on foliage were infected three weeks later. Activity of Colosoma coincided closely with population levels of the third generation of Anticarsia. Geocorid and nabid populations were severely affected by monocrotophos and methyl parathion treatments whereas diflubenzuron, a chitin inhibitor, had no apparent deleterious effect
