Relational Prior Knowledge Graphs for Detection and Instance Segmentation

Humans have a remarkable ability to perceive and reason about the world around them by understanding the relationships between objects. In this paper, we investigate the effectiveness of using such relationships for object detection and instance segmentation. To this end, we propose a Relational Prior-based Feature Enhancement Model (RP-FEM), a graph transformer that enhances object proposal features using relational priors. The proposed architecture operates on top of scene graphs obtained from initial proposals and aims to concurrently learn relational context modeling for object detection and instance segmentation.Experimental evaluations on COCO show that the utilization of scene graphs, augmented with relational priors, offer benefits for object detection and instance segmentation. RP-FEM demonstrates its capacity to suppress improbable class predictions within the image while also preventing the model from generating duplicate predictions, leading to improvements over the baseline model on which it is built.</p

Effect of interleukin 12 (IL-12) on embryonic development and yolk sac vascularisation

Background: In the recent days there has been an increase in diseases known as "angiogenic diseases" characterized by pathologic vascularisation. In the rat, the development of embryonic vessel starts to occur at 9.5 days of gestation. In mammals, the vascular system starts developing in a very early embryonic stage. The majority of rat embryo circulation system gets complete approximately at 11 - 12 days. Therefore the in vitro study of 9.5 - 11.5-day old embryo culture could be a suitable model to study the effects of angiogenic and antiangiogenic substances on yolk sac vascularisation. In the present study, the effects of Interleukin-12 (IL-12) on the yolk sac vascularisation are investigated during the in vitro embryo culture, where the latter angiogenic factor was added to serum

POTENTIAL NUTRITIVE VALUE OF ASTRAGALUS SPECIES HARVESTED AT THREE DIFFERENT MATURITY STAGES

The present study was conducted to investigate the effects of maturity stages on the chemical composition, in vitro gas and methane production, metabolic energy and organic matter digestibility for eleven Astragalus species widely encountered over the rangelands and intensely grazed by ruminants. Astragalus samples were collected from the rangelands at three different stages namely as before flowering, flowering and bear fruit stages. Dried samples were then subjected to various chemical analysis. Effects of Astragalus species and maturity stages on chemical composition, in vitro gas and methane production, metabolic energy and organic matter digestibility were found to be quite significant (P < 0.001). Acid detergent fiber (ADF) and neutral detergent fiber (NDF) ratios increased, while the crude protein, crude ash, crude oil, condensed tannin contents, gas and methane production levels decreased with the progress of maturity stage. It can be suggested that grazing was more favorable at before flowering or flowering stages of Astragalus species because of high crude protein and metabolic energy content of plant at these stages. Also, although all Astragalus species were considered as a quality feed source for ruminants, endemic Astragalus oocephalus and Astragalus longifolius species were prominent with their superior nutritive properties

The effect of green manure crops of legumes on grain yield and some agronomical characters of maize grown on different nitrogen doses [Degisik azot dozlarinda yetistirilen misir bitkisinde tane verimi ve bazi tarimsal ozelliklere bazi yesil gubre baklagil bitkilerinin etkisi]

In this research, the effect of green manure crops of legumes such as horsbean, mixture of horsbean+vetch, alexandrie klee, fenugreek on grain yield and some agronomical characters of maize grown on different nitrogen doses (0, 12 and 24 kg N da-1) were investigated. Also, dry matter of nodule, root and biomass of above ground and total amount of N were determined. According to the resulting two years, the total amount of N fixed to the soil by the way of nodule, root and biomass of above ground was between 27.5-38.8 kg da-1. Also it was determined that maize could be grown using less nitrogen fertilizer after the application of green manure. The grain yields of maize applied 24 kg N da-1 and 12 kg N da-1 after the growth of wheat were 1055 kg da-1 and 1141 kg da-1 respectively. The grain yields of maize applied 12 kg N/da-1 after the growth of mixture of horsbean+vetch, fenugreek and horsbean and alexandria klee were 1141, 1122, 1124, 1207 kg da-1 respectively. It was determined that after the application of green manure, maize could be sown earlier than the crop system of wheat+maize cultivated commonly in Cukurova region

OBJETIVO: o presente estudo investigou o controle vertical e os efeitos do tratamento ortodôntico em pacientes dolicofaciais, empregando o AEB cervical e o arco base inferior. MÉTODOS: foi realizada a avaliação cefalométrica de 26 pacientes dolicofaciais com Classe II, divisão 1, idade média de 114 meses. O tratamento ortodôntico envolveu a utilização do AEB cervical na arcada superior e arco base na arcada inferior, até a obtenção da chave de oclusão normal dos molares, e finalizado segundo a Terapia Bioprogressiva, com duração média de 56 meses. Foram avaliados os valores de FMA, SN.GoGn, ANB, Fg-S, S-FPm, comprimento maxilar, comprimento mandibular, AFP (altura facial posterior), AFA (altura facial anterior), IAF (índice de altura facial), ângulo do plano oclusal, ângulo do plano palatino, QT (queixo total), LS (lábio superior) e ângulo Z. RESULTADOS: o tratamento promoveu estabilidade dos planos mandibular, oclusal e palatino. Ocorreu a correção anteroposterior das bases apicais, verificada pela redução significativa da grandeza ANB. A maxila apresentou um suave deslocamento anterior,com um suave aumento da dimensão anteroposterior.A mandíbula apresentou melhora de seu posicionamento em relação à base do crânio e sua dimensão anteroposterior aumentou significativamente. As alturas faciais posterior e anterior permaneceram em equilíbrio, não alterando significativamente o IAF. O perfil tegumentar apresentou melhora significativa. CONCLUSÃO: o tratamento realizado promoveu a correção das bases apicais, com controle dos planos horizontais e das alturas faciais, sendo efetivo no controle vertical.<br>OBJECTIVE: This study investigated vertical control and the effects of orthodontic treatment on dolichofacial patients, using cervical headgear (CHG) and lower utility arch. METHODS: Cephalometric assessment of 26 dolichofacial patients with Class II, division 1, and mean age of 114 months. Orthodontic treatment involved the use of cervical headgear (CHG) in the maxillary arch, lower utility arch in the mandibular arch until normal occlusion of the molars was obtained and finished in accordance with Bioprogressive therapy, with a mean duration of 56 months. The values of FMA, SN.GoGn, ANB, Fg-S, S-FPm, maxillary length, mandibular length, posterior facial height (PFH), anterior facial height (AFH), facial height index (FHI), occlusal plane angle (OPA), palatal plane angle (PPA), total chin (TC), upper lip (UL) and Z angle were evaluated. RESULTS: The results showed that treatment promoted stability of the mandibular, occlusal and palatal planes. Anteroposterior correction of the apical bases occurred, verified by the significant reduction in the variable ANB. The maxilla presented slight anterior displacement and increase in the anteroposterior dimension. The mandible presented improvement in its position in relation to the cranial base and its anteroposterior dimension increased significantly. The posterior and anterior facial heights remained in equilibrium, with no significant alteration in FHI. The tegumental profile presented significant improvement. CONCLUSION: The treatment performed produced correction of the apical basis with control of the horizontal planes and facial heights, and was effective for vertical control

Reliability and Validity of Turkish Version of the Simplified Nutritional Appetite Questionnaire (SNAQ)

Objective: We aimed to investigate reliability and validity of the Turkish version of the Simplified Nutritional Appetite Questionnaire (SNAQ) in geriatric outpatients.Design/Setting: A cross-sectional study was designed through 2013-2016 years. At first, translation and back translation processes of the SNAQ from English to Turkish languages were done consecutively. Then construct validity was performed. Participants: They were recruited among the outpatients aged >=60 years that were consecutively admitted to the geriatric outpatient clinic of the Istanbul University hospital. Measurements: Demographic data was recorded. SNAQ, Mini Nutritional Assessment (MNA), six-item Katz activities of daily living (ADL) and eight-item Lawton instrumental activities of daily living (IADL) scales were applied. Results: 442 participants consisted of 305 women and 137 men with a mean age of 77.1 +/- 6.8 years. The SNAQ identified 21.5% (n=95) of the participants with poor appetite. Reliability analysis showed good inter-rater reliability (r=0.693, p<0.05) and test-retest stability (r=0.654, p<0.05). Cronbach's alpha coefficient was 0.522. In terms of construct validity of SNAQ, Cohen's kappa analysis showed fair to moderate agreement between SNAQ and MNA (x = 0,355, p<0.001). Female gender, being illiterate, functional dependency in IADL were significantly associated with poor appetite. The SNAQ score was weakly correlated with scores of MNA-SF and MNA-LF (r=0.392 and r=0.380, respectively, p<0.0001 for both). There was statistically significantbut negligible correlation between the SNAQ and Katz ADL index, Lawton IADL index, and age. Conclusion: Turkish version of the SNAQ is a simple measurement with sufficient reliability and validity to screen poor appetite in community-dwelling older adults
