Illustrating changes in landscapes of passing opportunities along a set of competitive football matches

This study aims to illustrate the landscape of passing opportunities of a football team across a set of competitive matches. To do so positional data of 5 competitive matches was used to create polygons of pass availability. Passes were divided into three types depending on the hypothetical threat they may pose to the opposing defense (penetrative, support, and backwards passes). These categories were used to create three heatmaps per match. Moreover, the mean time of passing opportunities was calculated and compared across matches and for the three categories of passes. Due to the specificity of player’s interactive behavior, results showed heatmaps with a variety of patterns. Specifically the fifth match was very dissimilar to the other four. However, characterizing a football match in terms of passing opportunities with a single heatmap dismisses the variety of dynamics that occur throughout a match. Therefore, three temporal heatmaps over windows of 10 min were presented highlighting on-going dynamical changes in pass availability. Results also display that penetrative passes were available over shorter periods of time than backward passes that were available shorter than support passes. The results highlight the sensibility of the model to different task constrains that emerge within football matches.info:eu-repo/semantics/publishedVersio

PERÍODO ANTERIOR A INTERFERÊNCIA E COMPONENTES DE PRODUTIVIDADE DA SOJA TRANSGÊNICA EM FUNÇÃO DO MÉTODO DE SEMEADURA

The aim of this study was to evaluate the influence of no-tillage and conventional tillage systems over the period before weed interference (PBI) and the effects on the soybean cv. BRS 243-RR yield components. The experimental design was arranged in completely randomized blocks, and the treatments consisted of increasing periods of control (0, 5, 10, 15, 21, 28, 35, 42, 49 e 125 days). The conventional tillage weed community was composed mainly by Brachiaria plantaginea, Ipomoea sp., Digitaria horizontalis and Cyperus rotundus; in no-tillage, Brachiaria plantaginea, Euphorbia heterophylla, and Ipomoea sp. were the most frequent weeds. The conventional tillage showed higher population and dry mass of weeds during the assessment period.  Regarding to the crop yield components, number of pods per plant was the most severely affect by competition; number of seeds per pod and weight of thousand grains were less affected by competition. Considering 5% of tolerance on soybean grain yield reduction, the period before interference happened 12 days after emergence (DAE) in the conventional tillage system and 17 DAE in no-tillage. The weed interference during the full crop cycle reduced soybean grain yield in 74% in the conventional tillage and 63% in no-tillage.Objetivou-se com o trabalho avaliar o sistema de semeadura direta e convencional sobre o período anterior à interferência (PAI) e nos componentes de produtividade da soja, cv. BRS 243-RR. O delineamento experimental foi em blocos ao acaso, sendo os tratamentos constituídos pela combinação de dez períodos crescentes de convivência das plantas daninhas com a cultura (0, 5, 10, 15, 21, 28, 35, 42, 49 e 125 dias). Na área do sistema de semeadura convencional a comunidade infestante predominante foi Brachiaria plantaginea, Ipomoea spp., Digitaria horizontalis e Cyperus rotundus; na área de semeadura direta destacaram-se Brachiaria plantaginea, Euphorbia heterophylla e Ipomoea spp. O sistema de semeadura convencional apresentou maior população e massa seca de plantas daninhas ao longo do período de avaliação. Com relação aos componentes do rendimento o número de vagens por planta foi o mais afetado pela competição; o número de grãos por vagem e a massa de mil grãos mostraram-se menos responsivos aos efeitos da competição. Considerando 5% de tolerância na redução de produtividade da soja, o período anterior à interferência, no sistema de semeadura convencional, ocorreu aos 12 dias após a emergência (DAE) e, no sistema direto de cultivo, aos 17 DAE. A interferência das plantas daninhas com a cultura durante todo o ciclo reduziu o rendimento de grãos da soja em média 74% e 63%, nos sistemas convencional e direto, respectivamente

Genetic and agronomic assessment of cob traits in corn under low and normal nitrogen management conditions

With rising energy demands and costs for fossil fuels, alternative energy from renewable sources such as maize cobs will become competitive. Maize cobs have beneficial characteristics for utilization as feedstock including compact tissue, high cellulose content, and low ash and nitrogen content. Nitrogen is quantitatively the most important nutrient for plant growth. However, the influence of nitrogen fertilization on maize cob production is unclear. In this study, quantitative trait loci (QTL) have been analyzed for cob morphological traits such as cob weight, volume, length, diameter and cob tissue density, and grain yield under normal and low nitrogen regimes. 213 doubled-haploid lines of the intermated B73 × Mo17 (IBM) Syn10 population have been resequenced for 8575 bins, based on SNP markers. A total of 138 QTL were found for six traits across six trials using composite interval mapping with ten cofactors and empirical comparison-wise thresholds (P = 0.001). Despite moderate to high repeatabilities across trials, few QTL were consistent across trials and overall levels of explained phenotypic variance were lower than expected some of the cob trait × trial combinations (R2 = 7.3–43.1 %). Variation for cob traits was less affected by nitrogen conditions than by grain yield. Thus, the economics of cob usage under low nitrogen regimes is promising

Effect of herbicides on yield components of sugarcane genotypes

O método de manejo de plantas daninhas mais usado em cana-de-açúcar tem sido o químico. Porém, ocorre grande variação de tolerância dos genótipos dessa cultura aos herbicidas utilizados. Objetivou-se com este trabalho avaliar o efeito de herbicidas sobre os componentes de rendimento de genótipos de cana-de-açúcar. O delineamento experimental adotado foi de blocos casualizados, arranjado em parcelas subdivididas, com quatro repetições. Nas parcelas alocaram-se os tratamentos; ametryn (2000 g ha-1), trifloxysulfuron-sodium (22,5 g ha-1), ametryn + trifloxysulfuron-sodium (1463 + 37 g ha-1) e a testemunha capinada. Nas subparcelas foram dispostos os genótipos de cana-de-açúcar; RB72454, RB835486, RB855113, RB855156, RB867515, RB925211, RB925345, RB937570, RB947520 e SP80-1816. Os resultados demonstram que a fitotoxicidade dos herbicidas foi maior nos genótipos RB835486 e RB855113, em relação a testemunha capinada. O diâmetro de colmos dos genótipos RB867515, RB925211 e SP8018-16 não foi afetado pelos herbicidas nas doses utilizadas. O número de nós por planta e o número de plantas de cana-de-açúcar m-1 foram reduzidos pelo uso de trifloxysulfuron-sodium e ametryn + trifloxysulfuron-sodium nos genótipos RB867515, RB925211 e RB947520. A produtividade de açúcar do genótipo RB855156 foi menor ao se aplicar os herbicidas. Comparando-se todos os genótipos observou-se que o SP80-1816 e o RB867515 foram os mais tolerantes, sobressaindo-se aos demais. Com base nos resultados conclui-se que existe tolerância diferenciada dos genótipos de cana-de-açúcar aos herbicidas testados.The most used weed control method in the sugarcane crop nowadays is the chemical. However, there is a great variation in selectivity of the genotypes regarding these products. The aim of this work was to evaluate the effect of herbicides on yield components of sugarcane genotypes. It was used a randomized blocks design, in a split-splot, with four replicates. In the plots were allocated the treatments: ametryn (2000 g ha-1), trifloxysulfuron-sodium (22.5 g ha-1), ametryn + trifloxysulfuron-sodium (1,463 + 37 g ha-1) and the weeded control. In the subplots were the sugarcane genotypes: RB72454, RB835486, RB855113, RB855156, RB867515, RB925211, RB925345, RB937570, RB947520 and SP80-1816. Results show that herbicide phytotoxicity was higher in the RB835486 and RB855113 genotypes, when compared to the weeded control. Stalk diameter of ‘RB867515’, ‘RB925211’ and ‘SP8018-16’ was not affected when applying herbicides. The number of nodes per plant and the number of sugarcane plants per meter were affected by the use of trifloxysulfuron-sodium and ametryn + trifloxysulfuron-sodium in ‘RB867515’, ‘RB925211’ and ‘RB947520’. Sugarcane productivity of the RB855156 genotype was lower when applying the herbicides. Comparing all the genotypes among themselves and in the presence of the herbicides, it was observed that the ‘SP80-1816’ and the ‘RB867515’ were the most tolerant, standing out in relation to the others. Based on the results, it can be concluded that there is different tolerance of the sugarcane genotypes regarding the tested herbicides

Multi-scale stamps for real-time classification of alert streams

In recent years, automatic classifiers of image cutouts (also called "stamps") have shown to be key for fast supernova discovery. The upcoming Vera C. Rubin Observatory will distribute about ten million alerts with their respective stamps each night, which it is expected to enable the discovery of approximately one million supernovae each year. A growing source of confusion for these classifiers is the presence of satellite glints, sequences of point-like-sources produced by rotating satellites or debris. The currently planned Rubin stamps will have a size smaller than the typical separation between these point sources. Thus, a larger field of view image stamp could enable the automatic identification of these sources. However, the distribution of larger field of view stamps would be limited by network bandwidth restrictions. We evaluate the impact of using image stamps of different angular sizes and resolutions for the fast classification of events (AGNs, asteroids, bogus, satellites, SNe, and variable stars), using available data from the Zwicky Transient Facility survey. We compare four scenarios: three with the same number of pixels (small field of view with high resolution, large field of view with low resolution, and a proposed multi-scale strategy) and a scenario with the full ZTF stamp that has a larger field of view and higher resolution. Our multi-scale proposal outperforms all the scenarios, with a macro f1-score of 87.39. We encourage Rubin and its Science Collaborations to consider the benefits of implementing multi-scale stamps as a possible update to the alert specification.Comment: Submitted to ApJ

Treatment of early borderline lesions in low immunological risk kidney transplant patients : a Spanish multicenter, randomized, controlled parallel-group study protocol: the TRAINING study

Subclinical inflammation, including borderline lesions (BL), is very common (30-40%) after kidney transplantation (KT), even in low immunological risk patients, and can lead to interstitial fibrosis/tubular atrophy (IFTA) and worsening of renal function with graft loss. Few controlled studies have analyzed the therapeutic benefit of treating these BL on renal function and graft histology. Furthermore, these studies have only used bolus steroids, which may be insufficient to slow the progression of these lesions. Klotho, a transmembrane protein produced mainly in the kidney with antifibrotic properties, plays a crucial role in the senescence-inflammation binomial of kidney tissue. Systemic and local inflammation decrease renal tissue expression and soluble levels of α-klotho. It is therefore important to determine whether treatment of BL prevents a decrease in α-klotho levels, progression of IFTA, and loss of kidney function. The TRAINING study will randomize 80 patients with low immunological risk who will receive their first KT. The aim of the study is to determine whether the treatment of early BL (3rd month post-KT) with polyclonal rabbit antithymocyte globulin (Grafalon®) (6 mg/kg/day) prevents or decreases the progression of IFTA and the worsening of graft function compared to conventional therapy after two years post-KT, as well as to analyze whether treatment of BL with Grafalon® can modify the expression and levels of klotho, as well as the pro-inflammatory cytokines that regulate its expression. This phase IV investigator-driven, randomized, placebo-controlled clinical trial will examine the efficacy and safety of Grafalon® treatment in low-immunological-risk KT patients with early BL. : NCT04936282.
