Weight $q$-multiplicities for representations of the exceptional Lie algebra $\mathfrak{g}_2$

Given a simple Lie algebra $\mathfrak{g}$, Kostant's weight $q$-multiplicity formula is an alternating sum over the Weyl group whose terms involve the $q$-analog of Kostant's partition function. For $\xi$ (a weight of $\mathfrak{g}$), the $q$-analog of Kostant's partition function is a polynomial-valued function defined by $\wp_q(\xi)=\sum c_i q^i$ where $c_i$ is the number of ways $\xi$ can be written as a sum of $i$ positive roots of $\mathfrak{g}$. In this way, the evaluation of Kostant's weight $q$-multiplicity formula at $q = 1$ recovers the multiplicity of a weight in a highest weight representation of $\mathfrak{g}$. In this paper, we give closed formulas for computing weight $q$-multiplicities in a highest weight representation of the exceptional\linebreak Lie algebra $\mathfrak{g}_2$.

Log BPS numbers of log Calabi-Yau surfaces

Let ( S , E ) (S,E) be a log Calabi-Yau surface pair with E E a smooth divisor. We define new conjecturally integer-valued counts of A 1 \mathbb {A}^1 -curves in ( S , E ) (S,E) . These log BPS numbers are derived from genus 0 log Gromov-Witten invariants of maximal tangency along E E via a formula analogous to the multiple cover formula for disk counts. A conjectural relationship to genus 0 local BPS numbers is described and verified for del Pezzo surfaces and curve classes of arithmetic genus up to 2. We state a number of conjectures and provide computational evidence.

Attribution of changes in an intensity index

Several methods have been proposed to quantify the individual attribution to the changes in aggregate intensity, but rarely identified that one’s attribution to either the intensity “A/B” form or “B/A” form that both represent one kind of efficiency indexes (cost/benefit or benefit/cost) should be equal, which is defined as the reciprocal attribution rate test. We review some existing decomposition analysis methods and propose a new method for attribution of changes in an aggregate intensity index that satisfies factor-reversal test, time-reversal test, and reciprocal attribution rate test by transforming intensity into a multiplicative formula that does not depend on the denominator weight. A numeric illustration, sensitivity analysis, and actual case studies for China are further provided to verify and compare the scopes of application and economic meanings of different methods for attributing intensity indicators. This proposed new method is a suitable tool for scientists and policy-oriented institutions to well monitor and analyze intensity transition in particular.

ADOPTION OF FARMERS IN THE IMPLEMENTATION OF TOMATO GOOD HANDLING PRACTICES (GHP) IN VILLAGE SENANING SUBDISTRICT

Tomato plants are vegetables that are easily damaged (parisable) so that requires the application of Good Handling Practices (GHP) which aims to reduce post-harvest yield loss. The purpose of this Final Assignment study is to increase farmers' knowledge about the application of tomato GHPs, namely treatment from harvest to market. This Final Project was carried out in the village of Senaning, Pemayung Sub-District, Batanghari Regency, Jambi Province from March to July 2020. The method used was descriptive method and multiple linear regression. Respondents were taken as many as 30 people who were determined deliberately (purposive sampling), namely farmers who are members of the tomato farmer group. The results showed that of 30 respondents at the level of farmer adoption, there were 17 knowledge persons in the low category (56.7%) and 13 moderate people (43.3%). Factors that influence the adoption of farmers in the application of GHP tomatoes are divided into 7 namely age, education, experience of farming, the role of extension workers, extension activities, availability of information and availability of facilities and infrastructure. From the analysis of variance analysis (Anova), it was found that all seven independent variables had a significant effect on the adoption of GHP tomato farmers (0.000> 0.05). Partially using the multiple linear regression formula, the results found that 6 independent variables, namely age (0.003), education (0.017), experience of farming (0.001), role of extension workers (0.029), extension activities (0.008), and availability of information (0.048) influence significant towards the adoption of farmers in the application of tomato GHP (Sig <0.05). While the availability of production facilities does not affect the adoption of farmers in the application of tomato GHP (0.119). The strategy taken to increase the adoption of farmers in the application of tomato GHP is by conducting counseling of tomato GHP and making a demonstration plot of tomato plants. After counseling there was a significant increase in the knowledge of farmers on tomato GHP with the T test sig (0,000).

Universal third-trimester ultrasonic screening using fetal macrosomia in the prediction of adverse perinatal outcome: A systematic review and meta-analysis of diagnostic test accuracy.

The effectiveness of screening for macrosomia is not well established. One of the critical elements of an effective screening program is the diagnostic accuracy of a test at predicting the condition. The objective of this study is to investigate the diagnostic effectiveness of universal ultrasonic fetal biometry in predicting the delivery of a macrosomic infant, shoulder dystocia, and associated neonatal morbidity in low- and mixed-risk populations. We conducted a predefined literature search in Medline, Excerpta Medica database (EMBASE), the Cochrane library and ClinicalTrials.gov from inception to May 2020. No language restrictions were applied. We included studies where the ultrasound was performed as part of universal screening and those that included low- and mixed-risk pregnancies and excluded studies confined to high risk pregnancies. We used the estimated fetal weight (EFW) (multiple formulas and thresholds) and the abdominal circumference (AC) to define suspected large for gestational age (LGA). Adverse perinatal outcomes included macrosomia (multiple thresholds), shoulder dystocia, and other markers of neonatal morbidity. The risk of bias was assessed using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool. Meta-analysis was carried out using the hierarchical summary receiver operating characteristic (ROC) and the bivariate logit-normal (Reitsma) models. We identified 41 studies that met our inclusion criteria involving 112,034 patients in total. These included 11 prospective cohort studies (N = 9986), one randomized controlled trial (RCT) (N = 367), and 29 retrospective cohort studies (N = 101,681). The quality of the studies was variable, and only three studies blinded the ultrasound findings to the clinicians. Both EFW >4,000 g (or 90th centile for the gestational age) and AC >36 cm (or 90th centile) had >50% sensitivity for predicting macrosomia (birthweight above 4,000 g or 90th centile) at birth with positive likelihood ratios (LRs) of 8.74 (95% confidence interval [CI] 6.84-11.17) and 7.56 (95% CI 5.85-9.77), respectively. There was significant heterogeneity at predicting macrosomia, which could reflect the different study designs, the characteristics of the included populations, and differences in the formulas used. An EFW >4,000 g (or 90th centile) had 22% sensitivity at predicting shoulder dystocia with a positive likelihood ratio of 2.12 (95% CI 1.34-3.35). There was insufficient data to analyze other markers of neonatal morbidity. In this study, we found that suspected LGA is strongly predictive of the risk of delivering a large infant in low- and mixed-risk populations. However, it is only weakly (albeit statistically significantly) predictive of the risk of shoulder dystocia. There was insufficient data to analyze other markers of neonatal morbidity.

Clinical Validation of Eleven Formulas for Calculating LDL-C in Iran.

Background & Objective:Concentration of low-density lipoprotein (LDL) is a known risk factor for cardiovascular disease which is routinely measured or calculated as LDL-C in clinical laboratories. In order to decrease the cost, instead of its measuring, it is recommended to calculate it using multiple formulas that have been introduced up to now. The aim of this study was to assess the results of various formulas and comparison of these results with those of measuring method and to clarify the best formula for the Iranian population.Methods:Concentrations of total cholesterol (TC), triglyceride (TG), cholesterol of high-density lipoprotein (HDL-C) and LDL-C in serums of 471 overnight fasting individuals were measured and also LDL-Cs of these samples were calculated by eleven different formulas according to their TC, TG, and HDL-C concentrations. Subsequently, results of measured and calculated LDL-C were analyzed statistically by paired t-test, correlation coefficient, and Passing-Bablok regression. In addition, for clinical evaluation, the differences between calculated and measured mean results were calculated and compared with an allowable total error.Results:Paired t-test unraveled a significant difference between the results of measured and calculated LDL-C by various formulas. But for some formulas, these differences were not clinically significant. The best clinical and statistical agreement (correlation coefficient) was obtained by the Friedewald equation.Conclusion:By using validated methods which have correct calibration and control system for measuring TC, TG, and HDL-C, we can use the Friedewald formula for calculating LDL-C in serum samples with TG up to 400 mg/dL.

Gluon bremsstrahlung in relativistic heavy ion collisions

We study the process $qq\rightarrow qqg$ at lowest order in QCD perturbation theory to understand gluon radiation in the fragmentation region of relativistic heavy-ion collisions. We arrive at a formula for gluon multiplicity that interpolates between $\sim 1/k_{\bot}^2$ behavior at low $k_{\bot}$, to $\sim 1/k_{\bot}^4$ at large $k_{\bot}$.

Testing the utility of condition indices in nestling swallows: a quantitative magnetic resonance approach

Nutritional condition is a key factor influencing the survival of migratory birds, and condition indices derived from morphometric measurements are commonly used to assess nutrient and energy stores. The performance and utility of condition indices used to examine energetics of growing juvenile birds remain uncertain. Recently, quantitative magnetic resonance (QMR) has been used to provide a non-invasive and non-lethal way to obtain measures of body composition. We calculated three widely used body condition indices using both wing length and tarsus length for nestling Barn Swallows Hirundo rustica erythrogaster at two ages (Day 8 and 15) and compared them to relative fat and lean mass calculated using QMR measurements. Additionally, we used QMR to develop multiple regression formulas to predict nestling fat mass, lean mass, and fat-free lean body mass (LBM) from easily obtainable body metrics. In Day 8 birds, variation in both relative fat mass and relative lean mass were adequately explained by total body mass alone, but this relationship was strongest for lean mass. Almost every condition index evaluated failed to explain variation in relative fat or lean mass in Day 15 birds. While our best multiple regression formulas for predicting fat mass and LBM had low predictive power, our formulas for predicting lean mass were precise (R2 > 90%) in both ages, providing a method to estimate the lean mass of nestlings from more readily obtainable metrics. Estimates of fat mass calculated from LBM and total body mass showed poor precision (R2 ≤ 30%).

On Kostant’s weight q-multiplicity formula for $$\mathfrak {sl}_{4}(\mathbb {C})$$

The q-analog of Kostant’s weight multiplicity formula is an alternating sum over a finite group, known as the Weyl group, whose terms involve the q-analog of Kostant’s partition function. This formula, when evaluated at $$q=1$$ , gives the multiplicity of a weight in a highest weight representation of a simple Lie algebra. In this paper, we consider the Lie algebra $$\mathfrak {sl}_4(\mathbb {C})$$ and give closed formulas for the q-analog of Kostant’s weight multiplicity. This formula depends on the following two sets of results. First, we present closed formulas for the q-analog of Kostant’s partition function by counting restricted colored integer partitions. These formulas, when evaluated at $$q=1$$ , recover results of De Loera and Sturmfels. Second, we describe and enumerate the Weyl alternation sets, which consist of the elements of the Weyl group that contribute nontrivially to Kostant’s weight multiplicity formula. From this, we introduce Weyl alternation diagrams on the root lattice of $$\mathfrak {sl}_4(\mathbb {C})$$ , which are associated to the Weyl alternation sets. This work answers a question posed in 2019 by Harris, Loving, Ramirez, Rennie, Rojas Kirby, Torres Davila, and Ulysse.

Semi-classical analysis of piecewise quasi-polynomial functions and applications to geometric quantization

Motivated by applications to multiplicity formulas in index theory, we study a family of distributions Θ(m;k) associated to a piecewise quasi-polynomial function m. The family is indexed by an integer k∈Z>0, and admits an asymptotic expansion as k→∞, which generalizes the expansion obtained in the Euler–Maclaurin formula. When m is the multiplicity function arising from the quantization of a symplectic manifold, the leading term of the asymptotic expansion is the Duistermaat–Heckman measure. Our main result is that m is uniquely determined by a collection of such asymptotic expansions. We also show that the construction is compatible with pushforwards. As an application, we describe a simpler proof that formal quantization is functorial with respect to restrictions to a subgroup.
