Applications of W-algebras to BF theories, QCD and 4D Gravity

We are able to show that BF theories naturally emerge from the coadjoint orbits of $W_2$ and $w_\infty$ algebras which includes a Kac-Moody sector. Since QCD strings can be identified with a BF theory, we are able to show a relationship between the orbits and monopole-string solutions of QCD. Furthermore, we observe that when 4D gravitation is cast into a BF form through the use of Ashtekar variables, we are able to get order $\hbar$ contributions to gravity which can be associated with the $W_2$ anomaly. We comment on the relationship to gravitational monopoles.Comment: 14 page

The Women Farmers Group (KWT) Mardika and Tirosa are a farmer group in Uel Hamlet, Nunkurus Village. Nunkurus Village is located in the East Kupang District, Kupang Regency, located ± 37 km east of Kupang City, has 4 hamlets, 10 RW and RT 20. The population of Nunkurus consists of 755 households (700 farmer households and 55 non-farmer families), with a total population of 3,293 consisting of 1,696 men and 1,595 women. Uel is a hamlet in Nunkurus, where this hamlet has 3 RW and 6 RT, with a total of 145 KK Farmers, the area of ​​dry land in Uel is 670 Ha, of which only 200 ha have been processed, the rest are mixed forest, shrubs and sleeping area. The problem faced by KWT partners Mardika and Tirosa in Uel Hamlet, Nunkurus Village, is how to increase the selling value of corn products which are usually sold in dry shelled form, by processing them to increase the selling value. How to design and build a grinding machine as well as a filter with a certain size and how to maintain good quality of ground corn products. This activity aims to change the product from shelled corn into corn flour and corn rice so that it has a higher selling value. From the results of the application of technology to group partners, namely KWT Mardika and KWT Tirosa, there was an increase in income with the application of the technology provided by 20% of the original income, the technology provided adapted to the business carried out by partners, and produced milled corn products with a size of 100 mesh. , 25 mesh and 6 mesh. The product forms are corn flour, fine grain corn rice and coarse grain corn rice

An Institutional Framework for Heterogeneous Formal Development in UML

We present a framework for formal software development with UML. In contrast to previous approaches that equip UML with a formal semantics, we follow an institution based heterogeneous approach. This can express suitable formal semantics of the different UML diagram types directly, without the need to map everything to one specific formalism (let it be first-order logic or graph grammars). We show how different aspects of the formal development process can be coherently formalised, ranging from requirements over design and Hoare-style conditions on code to the implementation itself. The framework can be used to verify consistency of different UML diagrams both horizontally (e.g., consistency among various requirements) as well as vertically (e.g., correctness of design or implementation w.r.t. the requirements)

Neurocognitive outcome in young adults born late-preterm

Aim This study examined whether late-preterm birth (34+0 to 36+6wks+d gestational age) was associated with neurocognitive deficit in young adulthood, and whether small for gestational age (SGA) birth amplified any adversity. Method Participants derived from the prospective regional cohort study, the Arvo Ylppö Longitudinal Study (n=786; 398 females, 388 males) (mean age 25y 4mo, SD 8mo), born 1985 to 1986 late-preterm (n=119; 21 SGA, <−2 SD) and at term (37+0 to 41+6wks+d; n=667; 28 SGA) underwent tests of intelligence, executive functioning, attention, and memory, and reported their education. Results Those born late-preterm scored −3.71 (95% confidence interval [CI] −6.71 to −0.72) and −3.11 (95% CI −6.01 to −0.22) points lower on Full-scale and Verbal IQ than peers born at term. Compared with those born at term and appropriate for gestational age (≥−2 to <2 SD) Full-scale, Verbal, and Performance IQ scores of those born late-preterm and SGA were −9.45 to −11.84 points lower. After adjustments, differences were rendered non-significant, except that scores in Full-scale and Performance IQ remained lower among those born late-preterm and SGA. Interpretation Late-preterm birth, per se, may not increase the risk of poorer neurocognitive functioning in adulthood. But the double burden of being born late-preterm and SGA seems to increase this risk

Maternal early pregnancy body mass index and diurnal salivary cortisol in young adult offspring

Background Maternal early pregnancy overweight (body mass index [BMI] 25.0-29.9 kg/m(2)) and obesity (BMI >= 30 kg/m(2)) are associated with mental and physical health adversities in the offspring. Prenatal programming of the hypothalamic-pituitary-adrenal (HPA) axis has been put forward as one of the mechanisms that may play pathophysiological role. However, evidence linking maternal overweight and obesity with offspring HPA-axis activity is scarce. We studied if maternal early pregnancy BMI is associated with diurnal salivary cortisol, a marker of HPA-axis activity, in young adult offspring. Methods At a mean age of 25.3 (standard deviation [SD) = 0.6) years, 653 Arvo Ylppo Longitudinal Study participants collected saliva samples for cortisol analyses, at awakening, 15 and 30 min thereafter, 10:30AM, 12:00PM, 5:30PM and at bedtime. Maternal BMI was calculated from weight and height verified by a measurement in the first antenatal clinic visit before 12 weeks of gestation derived from healthcare records. Results Per each one kg/m(2) higher maternal early pregnancy BMI offspring diurnal average salivary cortisol was -1.4% (95% CI:-2.6, -0.2, p(FDR) = 0.033) lower, at awakening it was -2.4% (95% CI:-4.0, -0.7, p(FDR) = 0.025) lower and the morning average salivary cortisol was -2.0% (95% CI:-3.4,-0.5, p(FDR) = 0.017) lower. These associations were independent of the offspring's own young adulthood BMI, and other important covariates. Conclusion Our findings show that young adult offspring born to mothers with higher early pregnancy BMI show lower average levels of diurnal cortisol, especially in the morning. Whether these findings reflect prenatal programming of the offspring HPA-axis activity warrants further investigation.Peer reviewe

Childhood cognitive ability and physical activity in young adulthood

Objective: Childhood cognitive ability is associated with lifestyle in adulthood, including self-reported physical activity (PA). We examined whether childhood cognitive ability is associated with objectively-measured PA and sedentary time (ST) in young adulthood. Methods: Participants of the Arvo Ylppö Longitudinal Study (n=500) underwent tests of general reasoning, visuo-motor integration, verbal competence and language comprehension at the age of 56 months yielding a general intelligence factor score; at the age of 25 years they wore omnidirectional accelerometers for 9 days (Range=4-10 days) measuring overall daily PA (counts per minute, cpm), ST and light and moderate-to-vigorous PA (MVPA) (minutes), and completed a questionnaire on occupational, commuting, leisure-time conditioning and non-conditioning PA. Results: After adjustment for sex, age, BMI-for-age SD score at 56 months and mean of valid minutes of measurement period for PA, per each one SD increase in the childhood general intelligence factor score, overall daily PA decreased by -8.99 CPM/day, ST increased by 14.93 minutes/day, time spent in light PA decreased by -14.39 minutes/day, and the odds per each level increase in physical demandingness of the work and in time spent in non-conditioning leisure-time PA decreased by 38% and 31%, respectively (p-values<0.04). These associations were mediated via higher young adulthood level of education. Conclusions: In contrast to expected, in this cohort of young adults with high variability in PA, of whom many were still studying, higher childhood cognitive ability was associated with more objectively-measured and self-reported physical inactivity. Whether these findings persist beyond young adulthood is a subject of further studies
