Numerical evaluation of iterated integrals related to elliptic Feynman integrals

2021

We report on an implementation within GiNaC to evaluate iterated integrals related to elliptic Feynman integrals numerically to arbitrary precision within the region of convergence of the series expansion of the integrand. The implementation includes iterated integrals of modular forms as well as iterated integrals involving the Kronecker coefficient functions $g^{(k)}(z,\tau)$. For the Kronecker coefficient functions iterated integrals in $d\tau$ and $dz$ are implemented. This includes elliptic multiple polylogarithms.

Effects of the Enriched Sports Activities-Program on Executive Functions in Italian Children.

2020

Physical activity (PA) during childhood plays an important role in brain development. This role is played in both the structural domain, prefrontal cortex area, and in the functional domain, involving the higher cognitive functions, including the executive functions (EF). Working memory (WM), inhibition, and switching as fundamental EF were investigated in an Italian children sample before and after four months of an Enriched Sports Activities-Program (ESA-Program). EFs were assessed at pre-test and post-test using, respectively, the digit span test, the color word Stroop test, and the trail making test derived from Millisecond Software. The Italian sample was composed of 141 children aged …

Optimization of vehicle-trailer connection systems

2016

The three main requirements of a vehicle-trailer connection system are: en route stability, over- or under-steering restraint, minimum off-tracking along curved path. Linking the two units by four-bar trapeziums, wider stability margins may be attained in comparison with the conventional pintle-hitch for both instability types, divergent or oscillating. The stability maps are traced applying the Hurwitz method or the direct analysis of the characteristic equation at the instability threshold. Several types of four-bar linkages may be quickly tested, with the drawbars converging towards the trailer or the towing unit. The latter configuration appears preferable in terms of self-stability and…

Volcanic gas emissions and degassing dynamics at Ubinas and Sabancaya volcanoes; implications for the volatile budget of the central volcanic zone

2017

Abstract Emission of volcanic gas is thought to be the dominant process by which volatiles transit from the deep earth to the atmosphere. Volcanic gas emissions, remain poorly constrained, and volcanoes of Peru are entirely absent from the current global dataset. In Peru, Sabancaya and Ubinas volcanoes are by far the largest sources of volcanic gas. Here, we report the first measurements of the compositions and fluxes of volcanic gases emitted from these volcanoes. The measurements were acquired in November 2015. We determined an average SO 2 flux of 15.3 ± 2.3 kg s − 1 (1325-ton day − 1 ) at Sabancaya and of 11.4 ± 3.9 kg s − 1 (988-ton day − 1 ) at Ubinas using scanning ultraviolet spectr…

In Situ Observations of Ice Particle Losses in a Young Persistent Contrail

2018

We describe results of in situ observations of a 1 to 2-min old contrail in the vortex Phase generated from soot-rich exhaust (> 10^15 emitted soot particles per kg-fuel burned). Simultaneous measurements of soot (EIsoot) and apparent ice (AEIice) particle number emission indices show a pronounced anti-correlation in the vertical contrail profile. AEIice decrease by about 75% with increasing distance below the contrail-producing aircraft,while EIsoot increase by an equivalent relative fraction, therefore strongly suggesting sublimation causing the ice particle losses. Quantifying these losses in measurements helps to validate and improve contrail parameterizations used to estimate the clima…

Novel 4-(3-phenylpropionamido), 4-(2-phenoxyacetamido) and 4-(cinnamamido) substituted benzamides bearing the pyrazole or indazole nucleus: synthesis…

2019

Based on some common structural features of known compounds interfering with p53 pathways and our previously synthesized benzamides, we synthesized new ethyl 5-(4-substituted benzamido)-1-phenyl-1H-pyrazole-4-carboxylates 26a-c, ethyl 5-(4-substituted benzamido)-1-(pyridin-2-yl)-1H-pyrazole-4-carboxylates 27a-c and N-(1H-indazol-6-yl)-4-substituted benzamides 31a,b bearing in the 4 position of the benzamido moiety the 2-phenylpropanamido or 2-phenoxyacetamido or cinnamamido groups. A preliminary test to evaluate the antiproliferative activity against human lung carcinoma H292 cells highlighted how compound 26c showed the best activity. This last was therefore selected for further studies wi…

Associations of Sleep Quality, Anxiety, and Depression with Cognitive and Executive Functions among Community-Dwelling Women Aged 65 ≥ Years: A Cross…

2021

Background: The objective of this study was to evaluate the associations of sleep quality, anxiety, and depression with cognitive performance, executive functions, and verbal fluency among women aged ≥ 65 years. Methods: A cross-sectional study was conducted on 241 women (72.52 ± 3.93 years). Cognitive performance (Mini-Mental State Examination) and impairment (Montreal Cognitive Assessment), verbal fluency (Isaacs test) and executive function (Trail Making Test), Sleep quality (Pittsburgh Sleep quality Index) and anxiety and depression (Hospital Anxiety and Depression Scale) were determined. Results: The linear regression analysis indicated that anxiety, depression and age, were related to…

Rapid serial naming: relations between different stimuli and neuropsychological factors.

2004

We report two studies on rapid serial naming (RSN). Study 1 addressed the relations among RSN tasks comprising different stimuli. Separate components for RSN of alphanumeric and non-alphanumeric stimuli, as well as for tasks in which the stimuli alternated between categories were identified. In Study 2, phonological skills, processing speed, motor dexterity, and verbal fluency were found to explain RSN performance. The studies indicate: (1) that RSN tasks vary in their properties according to the stimuli used and according to the way the tasks are arranged, and (2) that RSN tasks are multi-componented.

Frontline Professionals Performing Collaborative Work with Low-Income Families: Challenges across Organizational Boundaries

2020

This article discusses certain challenges relating to interagency collaboration between the Norwegian Labour and Welfare Administration (NAV) and Child Welfare Services (CWS). We have asked what obstacles to holistic work with low-income families who receive measures from NAV and CWS simultaneously can be identified. The departure point is collaboration on a local project at the municipal level. The differences between the views of the individual services (and the mandates based on these views) with regard to parental obligations have proved challenging. Using the theory of institutional logic, we have explored how different logics have influenced these services’ approaches to parenthood an…
