Reproducibility in Electroorganic Synthesis—Myths and Misunderstandings
2021
Abstract The use of electric current as a traceless activator and reagent is experiencing a renaissance. This sustainable synthetic method is evolving into a hot topic in contemporary organic chemistry. Since researchers with various scientific backgrounds are entering this interdisciplinary field, different parameters and methods are reported to describe the experiments. The variation in the reported parameters can lead to problems with the reproducibility of the reported electroorganic syntheses. As an example, parameters such as current density or electrode distance are in some cases more significant than often anticipated. This Minireview provides guidelines on reporting electrosyntheti…

Empīriskā ticamības funkcija lineārai regresijai
2015
Bakalaura darbā tiek aplūkota empīriskās ticamības (EL) metode lineārai regresijai ar mērķi konstruēt empīriskās ticamības apgabalu vienfaktora lineārās regresijas koeficientiem. Konstruētie EL ticamības apgabali tiek salīdzināti ar parametriskās ticamības apgabaliem. Darbā tiek arī veikta jaudas analīze simulētiem datiem ar dažādi sadalītiem atlikumiem, kur EL metodes sniegums tiek salīdzināts ar t-testu lineārai un robustai regresijai. Tiek secināts, ka empīriskās ticamības metode ir strādā labi, taču tā ir jūtīga pret izlecēju ietekmi. Empīriskiem ticamības apgabaliem pārsvarā gadījumu nav elipses forma un viennozīmīgs novietojums attiecībā pret parametrisko ticamības apgabalu.
Modélisation des effets des systèmes de culture sur la dynamique de la plante parasite orobanche rameuse en interaction avec les adventices
2019
Reducing pesticide use is a major challenge in agriculture and involves developing more sustainable methods that rely on non-chemical cropping techniques and biological regulations according to agroecological principles. Branched broomrape (Phelipanche ramosa (L.) Pomel) is a root parasitic plant which infects crops and causes dramatic yield losses worldwide. Managing broomrape is complex because it requires combining several cropping techniques whithin a global weed management strategy because broomrape is also able to infect non-parasitic weeds. The aim of this thesis was to stynthetize knowledge on branched broomrape dynamics in agroecosystems and to aggregate it within a mechanistic mod…
Latviešu apguvēju pareizrakstības kļūdas franču valodā: Franču valodas centralizētā eksāmena rakstiskās daļas analīze
2017
Bakalaura darba mērķis ir noteikt latviešu apguvēju raksturīgākās pareizrakstības kļūdas franču valodā kā svešvalodā. Pētījuma pirmajā daļā tiek izpētīta franču valodas pareizrakstība. Tās ietvaros tiek aplūkota saikne starp franču valodas mutisko un rakstisko aspektu, tāpat arī tiek analizēta franču valodas pareizrakstība un tās īpatnības. Darbā fokuss tiek likts uz pareizrakstības kļūdu klasificēšanas problēmu, tiek aplūkoti galvenie iemesli, kuru dēļ valodas apguvēji pieļauj kļūdas. Pētījuma otrajā daļā tiek veikta kvalitatīvā un kvantitatīvā analīze, kurā tiek pētītas franču valodas centralizētā eksāmena rakstiskajā daļā pieļautās pareizrakstības kļūdas. Praktiskās daļas rezultāti lieci…
Partial-order reduction for parity games and parameterised Boolean equation systems
2022
AbstractIn model checking, reduction techniques can be helpful tools to fight the state-space explosion problem. Partial-order reduction (POR) is a well-known example, and many POR variants have been developed over the years. However, none of these can be used in the context of model checking stutter-sensitive temporal properties. We propose POR techniques for parity games, a well-established formalism for solving a variety of decision problems, including model checking. As a result, we obtain the first POR method that is sound for the full modal $$\upmu $$ μ -calculus. We show how our technique can be applied to the fixed point logic called parameterised Boolean equation systems, which pro…
Hexagonal Microparticles from Hierarchical Self-Organization of Chiral Trigonal Pd3L6 Macrotetracycles
2021
Construction of structurally complex architectures using inherently chiral, asymmetric, or multi-heterotopic ligands is a major challenge in metallosupramolecular chemistry. Moreover, the hierarchical self-organization of such complexes is unique. Here, we introduce a water-soluble, facially amphiphilic, amphoteric, chiral, asymmetric, and hetero-tritopic ligand derived from natural bile acid, ursodeoxycholic acid. We show that via the supramolecular transmetalation reaction, using nitrates of Cu(II) or Fe(III), and subsequently Pd(II), a superchiral Pd3L6 complex can be obtained. Even though several possible constitutional isomers of Pd3L6 could be formed, because of the ligand asymmetry a…
Comparative Analysis of Nuclear Matrix Elements of 0νβ+β+ Decay and Muon Capture in 106Cd
2021
Comparative analyses of the nuclear matrix elements (NMEs) related to the 0νβ+β+ decay of 106Cd to the ground state of 106Pd and the ordinary muon capture (OMC) in 106Cd are performed. This is the first time the OMC NMEs are studied for a nucleus decaying via positron-emitting/electron-capture modes of double beta decay. All the present calculations are based on the proton-neutron quasiparticle random-phase approximation with large no-core single-particle bases and realistic two-nucleon interactions. The effect of the particle-particle interaction parameter gpp of pnQRPA on the NMEs is discussed. In the case of the OMC, the effect of different bound-muon wave functions is studied. peerRevie…
Diverse partner selection with brood recombination in genetic programming
2018
The ultimate goal of learning algorithms is to find the best solution from a search space without testing each and every solution available in the search space. During the evolution process new solutions (children) are produced from existing solutions (parents), where new solutions are expected to be better than existing solutions. This paper presents a new parent selection method for the crossover operation in genetic programming. The idea is to promote crossover between two behaviourally (phenotype) diverse parents such that the probability of children being better than their parents increases. The relative phenotype strengths and weaknesses of pairs of parents are exploited to find out i…
