On Prefix Normal Words
2011
We present a new class of binary words: the prefix normal words. They are defined by the property that for any given length $k$, no factor of length $k$ has more $a$'s than the prefix of the same length. These words arise in the context of indexing for jumbled pattern matching (a.k.a. permutation matching or Parikh vector matching), where the aim is to decide whether a string has a factor with a given multiplicity of characters, i.e., with a given Parikh vector. Using prefix normal words, we give the first non-trivial characterization of binary words having the same set of Parikh vectors of factors. We prove that the language of prefix normal words is not context-free and is strictly contai…
Primární substantiva jako základ pro prefixální derivaci
2018
This article discusses a data set of about 50 derived words built with different international and Slavic prefixes. Base words fo r derivation are nouns which denote human beings in Czech and Polish languages. These base words form thefollowing subclasses: names ofaffinity (otec - ojciec father', dcera - córka 'daughter', tchyne - teściowa 'mother-in-lawj; physical and mental qualities (baba - baba 'old woman', brunet - brunet 'brunette', dlte - dziecko 'child'); knighthood(król-król 'king', clsar-cesarz 'emperorj andadministrative titles (rektor-rektor 'president', sekretar- sekretarz 'secretaryj; professions (kuryr - kurier 'messenger', kustod - kustosz 'custodian', lektor - lektor 'lectu…
The existence of solutions for the modified (p(x), q(x))-Kirchhoff equation
2022
We consider the Dirichlet problem-Delta(Kp)(p(x))u(x) - Delta(Kq)(q(x))u(x) = f(x, u(x), del u(x)) in Omega, u vertical bar(partial derivative Omega) = 0,driven by the sum of a p(x)-Laplacian operator and of a q(x)-Laplacian operator, both of them weighted by indefinite (sign-changing) Kirchhoff type terms. We establish the existence of weak solution and strong generalized solution, using topological tools (properties of Galerkin basis and of Nemitsky map). In the particular case of a positive Kirchhoff term, we obtain the existence of weak solution (= strong generalized solution), using the properties of pseudomonotone operators.
LA TUTELA DEI CONTRATTI A TERMINE ILLEGITTIMI CON LA P.A.: SUL RISARCIMENTO DEL DANNO RESTA APERTO IL TORNEO TRA I TRIBUNALI DI MERITO.
2013
Premesso un breve excursus del variegato panorama giurisprudenziale sulla determinazione del danno risarcibile per l'illegittima apposizione del termine a contratti stipulati con la p.a., in mancanza della conversione del contratto a tempo indeterminato nel settore del pubblico impiego e di un criterio univoco di quantificazione del pregiudizio economico, la nota analizza criticamente la soluzione interpretativa fornita dalla sentenza in commento. Il giudice condanna la p.a. a risarcire una somma pari alle retribuzioni “future”, che sarebbero state percepite dalla scadenza del termine illegittimo fino al raggiungimento dell'età pensionabile delle ricorrenti, utilizzando criteri volti a dila…
Do teachers’ professional vision and teaching experience always go hand in hand? Examining knowledge-based reasoning of Finnish Grade 1 teachers
2021
This mixed-method study explored 54 Finnish Grade 1 teachers' professional vision and teaching experience. Teachers' retrospective think-aloud interviews, conducted while watching their eye-tracking recordings of classroom actions, were analysed according to the domains of knowledge-based reasoning. Negative associations between teaching experience and amount of knowledge-based reasoning were found. The qualitative examination of three teachers with different amounts of teaching experience provided concrete examples and broadened the findings. We suggest that teachers’ knowledge-based reasoning should be seen not only as an ability that increases with experience but also as an ability that …
Radiographic Assessment of Tibiofibular Syndesmosis Injury with Different Durations and Types of Fixation
2022
Introduction: There is no consensus among orthopedic surgeons on the number of cortical layers (tricortical or quadricortical fixation) involved or the duration of syndesmotic fixation after a tibiofibular syndesmosis (TFSD)-injury treatment. The purpose of this study was to assess radiographic parameters following the treatment of TFSD injuries, with various time-windows of syndesmotic screw removal and numbers of cortical layers involved. Materials and Methods: Fifty-five patients, aged from 25 to 75 years, were included in the study. The follow-up period ranged from 2 years to 4 years and 2 months. The patients were subdivided into groups based on the duration of the syndesmotic fixation…
First observation and study of the K± → π±π0e+e− decay
2018
The NA48/2 experiment at CERN reports the first observation of the K-+/- -> pi(+/-)pi(0)e(+)e(-) decay from an exposure of 1.7 x 10(11) charged kaon decays recorded in 2003-2004. A sample of 4919 candidates with 4.9% background contamination allows the determination of the branching ratio in the full kinematic region, BR(K-+/- -> pi(+/-)pi(0)e(+)e(-)) = (4.24 +/- 0.14) x 10(-6). The study of the kinematic space shows evidence for a structure dependent contribution in agreement with predictions based on chiral perturbation theory. Several P- and CP-violating asymmetries are also evaluated.
The manipulation of Euribor: An analysis with machine learning classification techniques
2022
The manipulation of the Euro Interbank Offered Rate (Euribor) was an affair which had a great impact on in ternational financial markets. This study tests whether advanced data processing techniques are capable of classifying Euribor panel banks as either manipulating or non-manipulating on the basis of patterns found in quotes submissions. For this purpose, panel banks’ daily contributions have been studied and monthly variables obtained that denote different contribution patterns for Euribor panel banks. Thus, in accordance with the court verdict, banks are categorized as manipulating and non-manipulating and Machine Learning classification techniques such as Supervised Learning, Anomaly …
Column Adsorption Studies for the Removal of Ammonium Using Na-Zeolite-Based Geopolymers
2022
The aim of this study was to examine the removal of ammonium ions from a synthetic model solution by using Na-zeolite-based geopolymers. Na-zeolite (=analcime) is a residue from mining industry. Three adsorbents were prepared from Na-zeolite using different production steps and metakaolin as a blending agent. These novel adsorbents were investigated in a fixed-bed column system where the effects of different flow rates with the initial ammonium concentration of 40 mg/L were studied. The Thomas, Bohart–Adams and Yoon–Nelson breakthrough curve models fitted well with the experimental data with a high R2 value. After adsorption experiments, adsorbents were regenerated using a mixture of 0.2 M …
Jet fragmentation transverse momentum distributions in pp and p-Pb collisions at √s, √sNN = 5.02 TeV
2021
Jet fragmentation transverse momentum (jT) distributions are measured in proton-proton (pp) and proton-lead (p-Pb) collisions at √sNN = 5.02 TeV with the ALICE experiment at the LHC. Jets are reconstructed with the ALICE tracking detectors and electromagnetic calorimeter using the anti-kT algorithm with resolution parameter R = 0.4 in the pseudorapidity range |η| < 0.25. The jT values are calculated for charged particles inside a fixed cone with a radius R = 0.4 around the reconstructed jet axis. The measured jT distributions are compared with a variety of parton-shower models. Herwig and Pythia 8 based models describe the data well for the higher jT region, while they underestimate the low…
