On the mathematical properties of multi-loop scattering amplitudes through the loop-tree duality
2023
El asombroso desarrollo de los experimentos de física de altas energías, como el Gran Colisionador de Hadrones del CERN, ha permitido obtener datos de gran calidad. El interés por comprender estos datos ha dado lugar a la necesidad de aumentar la precisión de las predicciones teóricas correspondientes. En esta tesis se desarrolla desde sus fundamentos matemáticos un método enfocado en cálculos de alta precisión denominado Loop-Tree Duality (dualidad lazo-árbol). Presentamos una clasificación de los diagramas de Feynman con respecto a su topología más que en el número de loops, en donde todas las clases topológicas pueden tener un número arbitrario L de loops y que se distinguen en su topolo…
8.trinn elevers første møte med tekstprogrammering
2023
Programmering er fortsatt nytt i skolen, men inntil nå har hovedsakelig blokkprogrammering blitt brukt. Likevel er blokkprogrammering stort sett bare brukt i grunnskolen, og fra videregående og utover i arbeidslivet er det tekstprogrammering som foretrekkes. Denne studien undersøker 8.trinn elevers første møte med tekstprogrammering, og forsøker å svare på disse forskningsspørsmålene; 1. Hvilke utfordringer har elever i sitt første møte med Python? 2. Hvordan bruker 8.trinn elever sine erfaringer i Scratch til å løse oppgaver i Python? Teorien som danner grunnlaget for å besvare disse spørsmålene er teorien om instrumentell skapelse, her representert av Buteau et al. (2020) og en studie av …
Understanding altered contractile properties in advanced age : insights from a systematic muscle modelling approach
2023
Age-related alterations of skeletal muscle are numerous and present inconsistently, and the effect of their interaction on contractile performance can be nonintuitive. Hill-type muscle models predict muscle force according to well-characterised contractile phenomena. Coupled with simple, yet reasonably realistic activation dynamics, such models consist of parameters that are meaningfully linked to fundamental aspects of muscle excitation and contraction. We aimed to illustrate the utility of a muscle model for elucidating relevant mechanisms and predicting changes in output by simulating the individual and combined effects on isometric force of several known ageing-related adaptations. Simu…

How the Love of Truth Affects the Role of the Researcher : References to the “Third Mission” of Universities and References to the Field of Business …
2023
This chapter discusses and highlights the role and, therefore, the responsibility of the researcher, of the scholar, in the context of a university institution, which is not usually limited to knowledge, but also to its transfer into the sphere—in primis—of the universitas studiorum, as well as scolarium (in addition to magistrorum), starting with the concept of “truth” and, subsequently, that of “love”1. Certain prescriptive considerations, which could involve the aforementioned role and, therefore, the ethics of the modus operandi of the researcher in question, with inevitable references to the purposes of their work and their goal of progress for mankind and society, will tendentially be…
The Solution Path of SLOPE
2023
The SLOPE estimator has the particularity of having null components (sparsity) and components that are equal in absolute value (clustering). The number of clusters depends on the regularization parameter of the estimator. This parameter can be chosen as a trade-off between interpretability (with a small number of clusters) and accuracy (with a small mean squared error or a small prediction error). Finding such a compromise requires to compute the solution path, that is the function mapping the regularization parameter to the estimator. We provide in this article an algorithm to compute the solution path of SLOPE.
Mentiras piedosas para lugares de memória? O mito das Cortes de Lamego na história constitucional de Portugal
2023
Despite their dubious authenticity, the laws adopted at the Cortes de Lamego of 1143 (an equally disputed date) were seen as the basis of Portugal's customary constitution from the time of their timely rediscovery in the early 17th century during Spanish rule (1580-1640). Until the period of the New State (1933-1974), their political and constitutional use served almost every cause, even the most opposed: Portuguese independence, at the time of the Restoration (1640-1668); national sovereignty and human constituent power at the time of the liberal revolution of Porto (1820-1822); the submission of men to the divine constituent power, implying the respect of the historical and/or natural con…
MAFLD: a multisystem disease
2023
Nonalcoholic fatty liver disease (NAFLD), affecting about 25% of general population and more than 50% of dysmetabolic patients, is an emerging cause of chronic liver disease and its complications. Recently, an international consensus of experts proposed to rename this disease as ‘Metabolic dysfunction-Associated Fatty Liver Disease’ (MAFLD) to focus on the bidirectional interplay between fatty liver and metabolic alterations and to stress the need of assessing fatty liver independently from alcohol consumption and other coexisting causes of liver disease. The peculiarity of NAFLD/MAFLD lies in the presence of a higher risk of not only – as expected – liver-related events but also of extrah…

Preoperative oral practices and incidence of postoperative complications in hospital medical-surgical procedures: A meta-analysis
2023
Oral decay prior to a hospital medical-surgical procedure is a risk factor for the development of postoperative complications. However, perioperative oral practices as a protective factor have not been studied. This review aims to evaluate the effectiveness of perioperative oral practices in the reduction of risk of developing postoperative complications in in-hospital medical surgical procedures. This review and meta-analysis was conducted according to Cochrane guidelines. Medline, Scopus, Scielo, and Cochrane were consulted. Articles of the previous 10 years concerning adult patients undergoing perioperative oral practices prior to hospital medical-surgical procedures, were included. Dat…

Understanding the Microfoundations of Entrepreneurial Ecosystems: Toward a Value-Based Method and Theory
2023
Despite the progress made by scholars, empirically investigating entrepreneurial ecosystems (EEs) remains problematic because of the inherent complexities and nonlinearities of interactions among EE actors. The research to date has shown a tendency to focus on macrolevel ecosystem dynamics while neglecting the microfoundations of EEs. We contend that this negligence is due to a lack of appropriate methodologies that can capture EE microfoundations through a systemic value-based perspective. To fill this gap, in this article, we propose a novel methodological approach, the value system method, which enables framing EEs through critical causal interdependences between key actors’ business mod…

Heterometallic Au(I)–Cu(I) Clusters : Luminescence Studies and 1O2 Production
2023
Two different organometallic gold(I) compounds containing naphthalene and phenanthrene as fluorophores and 2-pyridyldiphenylphosphane as the ancillary ligand were synthesized (compounds 1 with naphthalene and 2 with phenanthrene). They were reacted with three different copper(I) salts with different counterions (PF6–, OTf–, and BF4–; OTf = triflate) to obtain six Au(I)/Cu(I) heterometallic clusters (compounds 1a–c for naphthalene derivatives and 2a–c for phenanthrene derivatives). The heterometallic compounds present red pure room-temperature phosphorescence in both solution, the solid state, and air-equilibrated samples, as a difference with the dual emission recorded for the gold(I) precu…
L-Shaped Heterobidentate Imidazo[1,5-a]pyridin-3-ylidene (N,C)-Ligands for Oxidant-Free AuI/AuIII Catalysis
2023
In the last decade, major advances have been made in homogeneous gold catalysis. However, AuI/AuIII catalytic cycle remains much less explored due to the reluctance of AuI to undergo oxidative addition and the stability of the AuIII intermediate. Herein, we report activation of aryl halides at gold(I) enabled by NHC (NHC=N-heterocyclic carbene) ligands through the development of a new class of L-shaped heterobidentate ImPy (ImPy=imidazo[1,5-a]pyridin-3-ylidene) N,C ligands that feature hemilabile character of the amino group in combination with strong σ-donation of the carbene center in a rigid conformation, imposed by the ligand architecture. Detailed characterization and control studies r…

Parental influences on the development of single and co-occurring difficulties in reading and arithmetic fluency
2023
This study investigated how single and co-occurring difficulties in reading and arithmetic fluency developed among Finnish children across Grades 1–9 (N = 2151). Latent profile analysis among 391 children who had reading and/or arithmetic fluency difficulties in Grade 9 revealed profiles that followed three distinct patterns: reading difficulties (N = 121), mathematical difficulties (N = 94), and comorbid difficulties (N = 176). The profiles and typical performers were compared on parental reading and mathematical difficulties, parental education, the early home learning environment, and parental assistance with school homework across Grades 1–9. Results showed that although parents whose c…

Thermodynamic analysis of the interactions between human ACE2 and spike RBD of Betacoronaviruses (SARS-CoV-1 and SARS-CoV-2)
2023
There are many scientific reports on the interaction of the SARS-CoV-2 virus S protein (and its RBD) with the human ACE2 receptor protein. However, there are no reliable data on how this interaction differs from the interaction of the receptor binding domain of SARS-CoV-1 with ACE2, in terms of binding strength and changes in reaction enthalpy and entropy. Our studies have revealed these differences and the impact of zinc ions on this interaction. Intriguingly, the binding affinity of both RBDs (of SARS-CoV-1 and of SARS-CoV-2) to the ACE2 receptor protein is almost identical; however, there are some differences in the entropic and enthalpic contributions to these interactions.
Spectroscopy along flerovium decay chains. III : Details on experiment, analysis, 282Cn, and spontaneous fission branches
2023
Flerovium isotopes (element Z=114) were produced in the fusion-evaporation reactions 48Ca+242,244Pu and studied with an upgraded TASISpec decay station placed in the focal plane of the gas-filled separator TASCA at the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt, Germany. Twenty-nine flerovium decay chains were identified by means of correlated implantation, α decay, and spontaneous fission events. Data analysis aspects and statistical assessments, primarily based on measured rates of various events, which laid the foundation for the comprehensive spectroscopic information on the flerovium decay chains, are presented in detail. Various decay scenarios of an excited state obse…

Climate Change Impact on the Hydropower Potential in Agder County
2023
Climate change poses significant uncertainties for the future of hydropower, both in terms of challenges and opportunities. This study uses an educational version of the HBV model to investigate climate change impact on the hydropower potential in Agder County over the next century. The results show that the model tends to overestimate the observed values, but results in a Nash-Sutcliffe efficiency of 73.4\% for calibration and 77.7\% for validation with a correlation of 89.0\%. This indicates that the model's simplicity does not surpass its accuracy. For annual discharge the study found that the RCP4.5 scenario predicted a 9\% increase close to 2100. The RCP8.5 scenario projected a more si…

Libertà personale e libertà di circolazione tra emergenza presente e incertezza futura
2023
The article deals with the notion of personal freedom as it is regulated by art. 13 of Italian Constitution, drawing the main differences with other fundamental rights, in particular with the freedom of movement (art. 16 Cost.). To this end, the paper explores the main doctrinal orientations and the most recent constitutional case-law on the subject; specifically, it proposes a reading of the motivational points of the judgment n. 127 of 2022 of the Italian Constitutional Court which resolved some touchy issues of constitutionality that arose during the pandemic emergency. In conclusion, the text questions, with a look at the near future, on the usability of traditional tools for the protec…
The physical activity of Spanish speleologists: accomplishment of recommendations and differences by sociodemographic variables
2023
Outdoor adventure activities are becoming more popular due to their potential health benefits, although there is little scientific information on speleology as a physical activity (PA). The purpose of this study is to expand the scientific evidence in this field in two ways: (a) describe the PA performed by speleologists, taking into account the variables of interest such as gender, age, education, speleological level, participation in 'Alpine' explorations and body mass index (BMI) and (b) identify how far the World Health Organization's (WHO) PA recommendations were accomplished (i.e.,150 min of moderate-intensity aerobic PA or 75 min of vigorous-intensity aerobic). A cross-sectional stud…
Sequential Iron-Catalyzed C(sp2)–C(sp3) Cross-Coupling of Chlorobenzamides/Chemoselective Amide Reduction and Reductive Deuteration to Benzylic Alcoh…
2023
Benzylic alcohols are among the most important intermediates in organic synthesis. Recently, the use of abundant metals has attracted significant attention due to the issues with the scarcity of platinum group metals. Herein, we report a sequential method for the synthesis of benzylic alcohols by a merger of iron catalyzed cross-coupling and highly chemoselective reduction of benzamides promoted by sodium dispersion in the presence of alcoholic donors. The method has been further extended to the synthesis of deuterated benzylic alcohols. The iron-catalyzed Kumada cross-coupling exploits the high stability of benzamide bonds, enabling challenging C(sp2)–C(sp3) cross-coupling with alkyl Grign…
