Sequential gallery for interactive visual design optimization

Visual design tasks often involve tuning many design parameters. For example, color grading of a photograph involves many parameters, some of which non-expert users might be unfamiliar with. We propose a novel user-in-the-loop optimization method that allows users to efficiently find an appropriate parameter set by exploring such a high-dimensional design space through much easier two-dimensional search subtasks. This method, called sequential plane search , is based on Bayesian optimization to keep necessary queries to users as few as possible. To help users respond to plane-search queries, we also propose using a gallery-based interface that provides options in the two-dimensional subspace arranged in an adaptive grid view. We call this interactive framework Sequential Gallery since users sequentially select the best option from the options provided by the interface. Our experiment with synthetic functions shows that our sequential plane search can find satisfactory solutions in fewer iterations than baselines. We also conducted a preliminary user study, results of which suggest that novices can effectively complete search tasks with Sequential Gallery in a photo-enhancement scenario.

C9 Petroleum Resin Hydrogenation over a PEG1000-Modified Nickel Catalyst Supported on a Recyclable Fluid Catalytic Cracking Catalyst Residue.

A PEG1000-modified nickel-based catalyst (Ni-PEG1000/FC3R) supported on an activated fluid catalytic cracking catalyst residue (FC3R) was synthesized and applied to C9 petroleum resin (C9PR) hydrogenation. The results of the Brunauer–Emmett–Teller method, X-ray diffraction, H2 temperature-programmed reduction, and scanning electron microscopy–energy-dispersive X-ray spectroscopy show that the Ni-PEG1000/FC3R catalyst had a smaller crystallite size and higher Ni dispersion than those of a Ni/FC3R catalyst. The prepared Ni-PEG1000/FC3R catalyst was applied in a hydrogenation of C9PR at 270 °C and 6 MPa H2 pressure for 3 h. Under these conditions, the bromine value of C9PR was decreased from 46.1 g Br/100 g (Gardner color grade no. 11) to 0.72 g Br/100 g (Gardner color grade no. 1), and the sulfur content was reduced from 25.7 to 1.66 mg kg–1. Experimental results show that the Ni-PEG1000/FC3R catalyst exhibited high activity and stability for C9PR hydrogenation.

Multi-Modal Sensing Platform for Continuous Analysis of Maple Syrup in Production Process

In this work, we propose a new multimodal method/platform for continuous maple syrup °Brix monitoring and color grading during the production process. It is based on different detection methods such as electrical impedance, electrochemical sensing and optical sensing. First, using electrochemistry sensing, the results of maximum detected current in obtained Voltammogram with cyclic-voltammetry (CV) analysis and generated currents for chronoamperometry experiments presents a high standard deviation higher than 50%. In addition, we report the impact of the temperatures on previously mentioned sensing techniques. We have observed that electrochemistral sensor with commercial electrodes in our experimental conditions did not provide reliable measurement for maple syrup industrial process for °Brix monitoring. When using electrical impedance sensing method, a polynomial fitting relationship was established between the electrical impedance and °Brix with a high fitting index (R <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ) of 0.895. Furthermore, an impedance offset must be considered when temperature is changing. Also, an optical sensor was used to detect the maple syrup grade. As the grade depends on the light transmission percentage through a known thickness of solution, a photodiode detector and a LED were used as grade sensor. Many LEDs with different wavelengths (green, yellow, red, blue and infrared) were tested on different maple syrup grades. Obtained results show that green LED is the most suitable one for maple syrup grade detection which can lead to a linear fit with high fitting index (R <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ) of 0.963 between voltage response of the photodiode detector and the light transmission which is converted to a maple syrup grade.

New quantitative trait locus (QTLs) and candidate genes associated with the grape berry color trait identified based on a high-density genetic map

BackgroundBerry color is an important trait in grapes and is mainly determined by the anthocyanin content and composition. To further explore the coloring mechanism of grape berries, the F1 population of Vitis vinifera ‘Red Globe’ × ‘Muscat Hamburg’ was used to map the color locus, and transcriptome analysis was performed to assist in screening candidate genes.ResultsA total of 438,407 high-quality single-nucleotide polymorphisms (SNPs) were obtained from whole-genome resequencing (WGS) of the population, and 27,454 SNPs were selected to construct a high-density genetic map. The selected SNPs were clustered into 19 linkage groups (LGs) spanning a genetic distance of 1442.638 cM. Berry color was evaluated by color grade, chromatic aberration, total anthocyanin content and anthocyanin composition. The Pearson correlation coefficients of these phenotypes in 2017 and 2018 were significant at the 0.01 level. The major color locus of MYBA1 and MYBA2 on LG2 was identified, explaining between 26 and 63.6% of all phenotypic variance. Furthermore, 9 additional QTLs with smaller effects were detected on Chr2, Chr4, Chr6, Chr11 and Chr17. Combined with the gene annotation and RNA-seq data, multiple new candidate genes were selected from the above QTLs.ConclusionThese results indicated that grape berry color is a quantitative trait controlled by a major color locus and multiple minor loci. Though the major color locus was consistent with previous studies, several minor QTLs and candidate genes associated with grape berry color and anthocyanin accumulation were identified in this study. And the specific regulatory mechanism still needs to be further explored.

Evaluation of Crohn's Disease Activity: Development of an Ultrasound Score in a Multicenter Study.

Our goal in this multicentric prospective study was 2-fold: first, to test the diagnostic accuracy of ultrasound, color Doppler imaging (CDI), and contrast-enhanced ultrasound (CEUS) in identifying disease activity in patients with Crohn's disease (CD) compared with endoscopy as the reference standard; and, second, to construct a sonographic score that allows disease activity to be detected. Seventy-two patients with CD from 3 hospitals underwent within a 30-day period both colonoscopy and ultrasound (US), including mural thickness, CDI, and CEUS, prospectively as part of clinical care. A multivariate analysis was carried out to assess the influence of each of the ultrasound variables in predicting endoscopic activity. We then developed a predictive ultrasound score for disease activity, and a receiver operating characteristic (ROC) curve was constructed to determine the area under the ROC curve (AUC) and the best cut-off score value to discriminate between active and inactive disease. Sonographic findings that were independent predictors of the presence of active disease at endoscopy were wall thickness, color grade, and contrast parameters. A score based on those variables showed high accuracy in predicting active disease, with an area under the ROC curve of 0.972. A simpler index, without contrast parameters, also showed high accuracy in detecting disease activity (AUC, 0.923). A score based on wall thickness, color Doppler grade, and contrast parameters showed high accuracy in predicting active disease. A score without including the use of contrast agent had practically similar results and is easier to use in monitoring response to treatment.

Color vision system to assess English walnut (Juglans Regia) kernel pellicle color

Abstract English walnut (Juglans regia) kernel pellicle color is an important component of consumer quality, as a breeding phenotype attribute, and a key factor affecting marketing price. It is part of the United States Department of Agriculture (USDA) grading criteria and it is assessed by trained Dried Fruit and Tree Nuts Association (DFA) of California inspectors, who visually segregate kernels into four DFA color categories: 1 (‘Extra light’), 2 (‘Light’), 3 (‘Light Amber’), and 4 (‘Amber’). The establishment of an objective and fast Color Visual System (CVS) will remove human variability and bias, adding consistency and can speed-up the color evaluation process. Therefore, a portable CVS was designed, built and its performance was evaluated using three datasets of kernels, with a diverse range of pellicle colors: 2,000 from a UC Davis seedling population, 1,238 from ‘Chandler’, and 857 from ‘Howard’ cultivars. Kernel pellicle color was measured using the DFA (1 to 4) visual scoring system, a colorimeter and the CVS. Relationships between these methods were analyzed using correlation, density plots, and stepwise logistic regression methodology was further applied to create a set of CVS kernel pellicle color prediction models, which can classify kernels into the DFA color categories. The CVS could segregate all 4095 kernel samples into the DFA color categories with an accuracy equal to 68.9 %. The use of independent prediction models per dataset significantly improved prediction: the ‘Chandler’ model was most accurate (88.8 %), followed by the seedling (80.4 %) and ‘Howard’ (75.1 %) models. Therefore, it is recommended that a cultivar-specific model be used to improve grading prediction accuracy. Model accuracy performance was further improved when the number of color categories was reduced to two categories by combining 1 (‘Extra Light’) and 2 (‘Light’) (Category 1), and 3 (‘Light Amber’) 4 (‘Amber’) (Category 2). Overall, the CVS used with a dataset-specific model described overall kernel pellicle color much better than a single colorimeter reading, making CVS a promising tool to assess kernel pellicle color. The CVS can be used as an objective and consistent method during commercial walnut kernel pellicle color grading and/or high-throughput phenotype breeding evaluation.

Centrifugation may eliminate false-positive leucocyte esterase strip test results caused by inflammatory arthritis in the diagnosis of knee infection: A pilot study.

AimsThe purpose of this study was to validate our hypothesis that centrifugation may eliminate false-positive leucocyte esterase (LE) strip test results caused by autoimmune diseases in the diagnosis of knee infection.MethodsBetween January 2016 and May 2019, 83 cases, including 33 cases of septic arthritis and 50 cases of aseptic arthritis, were enrolled in this study. To further validate our hypothesis, another 34 cases of inflammatory arthritis from the Department of Rheumatology of our institution were also included. After aspiration, one drop of synovial fluid was applied to LE strips before and after centrifugation. The results were recorded after approximately three minutes according to the different colour grades on the colour chart. The differences of LE results between each cohort were analyzed.ResultsBefore centrifugation, 46% (23/50) of the LE strip tests in the aseptic arthritis group were false-positives. Most of the false-positive results were due to inflammatory arthritis; after centrifugation, 78.3% (18/23) of the tests yielded negative results. Similar results were observed in cases from the Department of Rheumatology. The sensitivity of the centrifuged LE strip test was 0.818 (0.639 to 0.924), which is still an acceptable level compared with the uncentrifuged results, which yielded a sensitivity of 0.909 (0.745 to 0.976). However, the specificity was increased from 0.540 (0.395 to 0.679) to 0.900 (0.774 to 0.963) after centrifugation.ConclusionAlthough inflammatory arthritis can yield a false-positive LE strip test result in the diagnosis of knee infection, centrifugation may eliminate these false-positive results.Cite this article: Bone Joint Res. 2020;9(5):236–241.

Association analysis of the ovine KAP6-1 gene and wool traits in Barki sheep

Traditionally, sheep are raised in Egypt for meat and wool production. Selection for higher wool quality could increase its suitability for particular processing procedures in the wool industry, which maximizes the profit of the sheep production enterprise. In this research, the effect of genetic polymorphisms of the keratin-associated protein 6-1 (KAP6-1) on wool traits was investigated in Barki sheep. Animals were genotyped by polymerase chain reaction (PCR)-single strand conformation polymorphism (SSCP). Results identified a single nucleotide polymorphism (rs589531301, G > C) with three genotypes (GG, GC and CC) and the genotypic frequencies were 14.63, 43.82 and 41.55%, respectively. The KAP6-1 genotypes significantly (p > 0.05) affected greasy fleece weight (GFW; p = 0.05), prickle factor (PF; p = 0.02), staple length (SL; p = 0.038), fiber diameter (FD; p = 0.015), kemp score (KS; p = 0.048), greasy color grade (GCG; p = 0.037), luster grade (LS; p = 0.048) and the greasy structure (GS; p = 0.038). The noteworthy, animals with the CC genotype produce more wool (GFW = 1.116 kg) with longer SL (9.03 cm), finer wool (FD = 24.34 μm) and higher KS compared to other genotypes. The results of this report presented the KAP6-1 gene as a candidate gene to improve the wool production traits in the Egyptian Barki sheep and worldwide.

The purpose of this study is to examine the relationship between the grades assigned during initial CDDU encounter for Peyronie’s disease (PyD) and ultimate intervention pursued for treatment of the primary PyD defect. METHODS: During work-up for PyD, 522 patients were examined using penile CDDU performed by a single surgeon at our institution from 2005 to 2018. Doppler 2D images were reviewed by an independent examiner based on classification criteria as follows: Grade I- hypoechoic shadowing without calcification; Grade II- focal microcalcifications; Grade III- scattered microcalcifications; Grade IV- confluent calcified and palpable plaque (a) of the tunica albuginea or (b) of the septum. Retrospective review allowed identification of treatments pursued in each case. RESULTS: 522 patients were evaluated with median age of 60 years (IQR 54, 65). Degree of curvature measured at the time of CDDU was < 30 degrees in 10.8%, > 30 and <45 degrees in 14.2%, > 45 and <60 degrees in 27.2%, > 60 and <90 degrees in 15.1%, and > 90 degrees in 11.6%, with 21.1% of patients having an hourglass defect. A number of patients had concomitant Doppler diagnosis of arterial insufficiency (19.7%), CVOD (35.6%), or mixed arterial and venous insufficiency (9%). Review of Doppler imaging with application of the grading criteria for 522 patients resulted in the primary diagnosis of Grade I ultrasonographic appearance in 237 (45.4%) of patients, Grade II in 104 (29.9%) of patients, Grade III in 91 (17.4%) of patients, and Grade IV(a) and IV(b) in 83 (15.9%) and 7 (1.3%) of patients. Only 187 patients ultimately had invasive treatment for their PyD, with 50 patients undergoing xiaflex, 40 undergoing penile plication, 49 undergoing plaque incision and grafting, and 48 undergoing IPP placement. Our study did not find evidence of trends in surgery with increasing or decreasing CDDU classification score (p=0.83). Most patients (334, 64.1%) did not pursue invasive treatment for their PyD. CONCLUSIONS: Most patients in our cohort did not pursue invasive treatment for their PyD. There was no trend in surgery pursued based on classification score.

Development of criteria for determining the color saturation of gemstones

The urgency of the problem is conditioned by spectral methods development providing objectivity and accuracy of gemstones color grading. The purpose of the work: working-out the criteria which allows to determine gemstones saturation based on physicsmathematics patterns and spectral data. Methodology of the research: studying of colored gemstones transmittance spectra, discovery of the regularities and development of physics-mathematics methods for the color saturation grading. Results. The absolute and relative criteria for gemstone saturation grading was suggested as ratio of difference between light transmittance to squared difference between wavelengths at the area of basic chromophore element. Experimental data and allochromatic gemstones saturation calculation examples were presented considering spectral sensitivity of human eye. Summary. Gemstones absorption and transmittance spectra research allows to define tone and saturation gemstone color features. To improve tone and saturation definition accuracy, it is necessary to select standard hue of gemstones for wavelengths scale graduating along with spectral sensitivity of human eye.

Helping spine surgeons detect pre-surgical psychological distress in complex spine patients: an observational pilot study.

Retrospective analysis. Analysis of a standardized, pre-surgical psychological evaluation program for complex spine surgery. Adult spinal deformity (ASD) patients have a high rate of comorbid mental health conditions. Although there is a body of literature demonstrating the impact of psychological factors, including anxiety and depression, on spine surgery outcome, it is estimated that spine surgeons utilize a psychological assessment only about one third of the time prior to a patient's spine surgery. At this time, there is not a widely reported pre-surgical psychological evaluation program for ASD patients. 129 consecutive complex spine surgery candidates receiving a pre-surgical psychological evaluation were analyzed between January 1st 2014 and December 31st 2018. Based on the available literature and professional experience in our facility, a color code for patients was developed from Green (low psychological or psychosocial co-morbidity) to Red (high psychological or psychosocial co-morbidity). Univariate analysis was used to evaluate between color grades and demographics, mental health disorders and outcomes. 83% of complex spine patients had at least one psychological disorder or psychosocial barrier. Only 17% had a combination of realistic expectations for surgery, a good support plan, and were without a history of mental illness. The pre-surgical psychological color criteria were validated in showing higher rates of major depression, anxiety disorder, and bipolar disorder in moderate to severe color grades (p < .001) in addition to higher PHQ-9 and GAD-7 scores (p < .001). Patients having a more severe color grade had lower rates of a discharge home and were taking higher morphine equivalent dosages (MEDs) at their six-month follow-up, though both did not reach statistical significance (p = .07 and p = .08; respectively). A comprehensive pre-surgical psychological evaluation may be beneficial to risk stratify and counsel patients being evaluated for surgical reconstruction of adult spinal deformities. 3.

Comparing dryland cotton upland fibre quality from on-board spindle and stripper harvesting systems

On-board spindle and brush type stripper round module harvest systems were evaluated on commercial field scale for dryland Upland cotton in Australia over two harvest seasons. Observations on harvester performance, including harvesting efficiency, harvest loss, seed cotton yield and lint turn out were conducted at three locations, during the 2017 and 2018 cotton growing seasons, with a single variety. Fibre quality was measured by High Volume Instrumentation (HVI™) and Advanced Fiber Information System (AFIS) and analysed to determine if there were any significant differences between the two harvesting systems. The stripper harvesters had higher productivity (i.e. hectares per hour), harvested more material with lower harvest loss than the spindle harvesters. The seed cotton harvested by the stripper systems contained plant material which resulted in a lower lint turn out than the spindle harvester although the yield in bales ha−1 was still higher. There were no significant differences in fibre quality as measured by the HVI except for colour and trash. The significant differences in colour and trash did not affect the economic return to the grower as the visual colour and trash grades were below, i.e. better than, the Australian base grade. There were also no significant differences in the fibre quality as measured by AFIS. It is hypothesised that the reasons for this was due to the appropriate timing and application of defoliation, harvesting when moisture content ≤ 12%, reduced leaf allowing for gentler ginning and mature fibre.

Correlation between EPR spectra and coloration of natural diamonds

White diamonds color grading is one of the basic diamond evaluations. The color value based on a scale that ranges from D to Z, with D being the more colorless and more valuable, among other qualifications. As the diamond grade moves on this scale, its color appears more yellow progressively. This yellowish color, present only in Type I diamonds, is mainly due to the nitrogen related defects such as N3 center and C-center. The current color grading system is based on a visual method, where gemologist compares the sample with a Master Color set. However, this method is very subjective. Several defects responsible for light absorption in diamond are carrying electron spin and appear in Electron Paramagnetic Resonance (EPR) spectrum. In this study, we developed a new EPR based technique for a quantitative measurement of N3 center and C-center in diamond through quantitative EPR spectroscopy. The correlation between EPR spectra and color grades of diamond was established.

The Effect of Various Processing Stages During Ginning on Fiber Quality

This study was conducted to determine the effectiveness, in terms of cleaning efficiency and fiber quality, of the seed cotton cleaning stages installed in cotton gins that process predominately spindle-harvested, irrigated Upland cotton and to determine the effect of the various processing stages during ginning on gin turn out and fiber quality. The study showed that the average amount of trash content present in seed cotton was typically &lt; 10%. The seed cotton cleaning process was able to remove 20 to 40% with the remainder of the trash removed by subsequent lint cleaning stages. The study also showed that the gin stand has no influence on fiber quality provided that the gin stand was not overloaded, maintained to manufacturers recommendations, and moisture levels maintained within the recommended levels. Flow-through air lint cleaners had no significant effect on fiber quality with minimal reduction in trash. The controlled-batt saw lint cleaners had positive and significant effects on color and trash; negative effects on length, length uniformity, short fiber and nep content, elongation; and no effect on strength, micronaire, fineness, maturity, number and size of SCN and fiber nep size. The batt-less saw lint cleaners had similar effects on fiber quality, although not as severe. The controlled-batt saw lint cleaners were more aggressive than the batt-less saw lint cleaners and removed more trash and hence achieved a better color grade, with this improvement resulting in notable reductions in lint turn out, fiber length, and increased short fiber and nep content.

The Effect of Round Module Storage Time and Ambient Conditions On Cotton Quality

The adoption of round module cotton pickers expanded rapidly in Australia after their introduction in 2008. The objective of this study was to monitor changes in fibre quality as a result of storage time and changes in conditions within modules. Temperature, relative humidity and moisture content of seed cotton in plastic-wrapped round modules, and the resulting fibre quality, were monitored for extended periods of time across three locations over three seasons. All modules observed across seasons and locations had initial moisture contents of less than 12%, which was consistent with recommended practice. Moisture levels and temperature in the modules during storage closely followed but trailed changes in ambient weather conditions. With modules typically picked during late summer through to mid-autumn, conditions inside the modules typically cooled and dried during storage. The direction of the open module face affected the rate of drying and/or cooling, as did covering modules with a tarpaulin. Fibre quality was largely stable across storage periods of up to three months, although colour (yellowness) and fibre elongation consistently degraded, even after one month of storage. Over longer periods properties such as length and strength were negatively affected although changes, whilst statistically significant, were often small or inconsequential in terms of the commercial premium paid for these properties. From this study we conclude current guidelines for cotton harvesting and storage are applicable to these new round modules. Interestingly, the ‘negative’ changes in fibre yellowness often increased the value of cotton in terms of its USDA colour grade.

Reconstruction of Smooth 3D Color Functions from Keypoints: Application to Lossy Compression and Exemplar-Based Generation of Color LUTs

3D CLUTs (Color Look Up Tables) are popular digital models used in artistic image and video processing, for color grading, simulation of analog films, and more generally for the description and application of generic non-parametric color transformations. The relatively large size of these models leads to high data storage requirements when trying to distribute them on a large scale (e.g. several hundred at a time). In this article, an effective technique based on a multi-scale anisotropic diffusion scheme is proposed, for the lossy compression of generic CLUTs regularly sampled on a 3D grid. Our method exhibits high average compression rate, while ensuring visually indistinguishable differences with the original (uncompressed) CLUTs. In a second step, a variation of our algorithm for exemplar-based generation of CLUTs is developed, in order to create a complete CLUT from a single pair of before/after images that accounts for the color transformation.

The Pretibial edema strain ratio obtained by elastography can be used in differential diagnosis of patients with chronic heart failure and nephrotic syndrome

Objective: Pretibial edema (PTO) is a common examination finding in patients with both heart failure (HF) and nephrotic syndrome (NS). We aimed to evaluate the utility of PTO strain ratio (PTO-SR) obtained by strain elastography (SE) in the diagnosis of HF and NS.&#x0D; Materials and Methods: A total of 80 patients (40 patients with HF and 40 patients with NS) were included in this study. Physical examination echocardiography and laboratory examinations were performed. PTO elastographic color grade and PTO-SR measurements were performed in the PTO region by SE.&#x0D; Results: PTO-SR and presence of PTO elastographic color grade-I were found to be higher in HF. Tricuspid regurgitation pressure gradient (TRPG), left ventricular (LV) diameters and volumes were significantly higher and LV ejection fraction (EF) was significantly lower in HF. LVEF and PTO-SR independently determined the presence of HF. The each-0.1 increase in PTO-SR was being to the risk of HF by 29.1%. In predicting the presence of HF, the area under the ROC curve was 0.827 for PTO-SR. The cut-off value for PTO-SR was taken as 0.70, it was determined the patients with HF disease with 80.0% sensitivity and 76.5% specificity. PTO-SR value was found to be closely related to TRPG, LVEF, and LV volumes. A close relationship was found between PTO-SR and TRPG.&#x0D; Conclusion: In patients with HF, the PTO-SR obtained by SE is higher than in patients with NS and can be used as an objective parameter for HF differential diagnosis in addition to conventional HF diagnostic methods.

Performance of Scots Pine Seedlings from Seeds Graded by Colour

Research Highlights: One of the ways to improve the quality of a seedlot used in the forest nursery is the grading of seed by colour. Background and Objectives: The study is intended for forest’s engineers and owners because it offers an alternative solution for forest seeds improvement before sowing. The success of forest establishment program mainly depends on the quality of Forest Reproductive Material. At this time usual practices during the seed processing is seed grading on size. This causes a lot of controversy about the possible reduction of genetic diversity through directional selection. Materials and Methods: Aiming to study the effect of seed coat colour on seedling performance, a one-year old container seedlings of Pinus sylvestris L. were planted at the post-fire site. Seedlings were produced from three fractions, previously graded in the visible wavelength range on a standard optical separator, plus control obtained without separation by colour. Results: Seedlings from different seed fractions performed differently in the first growing season after planting on the field. Seedlings from light seed fraction grow better in height, but those from dark seed fraction resulted with the highest survival rate. Light-dark seeds, which constitute the largest group in the initial sample by absolute weight, resulted with seedlings of the lowest growth rates and survival. The good results showed by seedlings from the control, for both growth rates and survival, indicate the weak effect of seed colour grading on seedlings field performance, but also the need for the more comprehensive studies in the future.
