Reduction of Die Wear and Structural Defects of Railway Screw Spike Heads Estimated by FEM
(MDPI, 2021-11-15)
Railway spike screws are manufactured by hot forging on a massive scale, due to each kilometer of railway track needing 8600 spike screws. These components have a low market value, so the head must be formed in a single ...
Speed-up and slow-down of a quantum particle
(Nature Research, 2022)
[EN] We study non-relativistic propagation of Gaussian wave packets in one-dimensional Eckart potential, a barrier, or a well. In the picture used, the transmitted wave packet results from interference between the copies ...
Livestock activity biomarkers: Estimating domestication and diet of livestock in ancient samples
(Elsevier, 2021-12)
[EN]Faecal matter is commonly recovered from archaeological sites related to human/animal activity. The identification of its source is essential to understand the domestication process and the relationship between humans ...
A Review of Possible EEG Markers of Abstraction, Attentiveness and Memorisation in Cyber-Physical Systems for Special Education
(Frontiers Media, 2021-11-02)
[EN]Cyber-physical systems (CPSs) for special education rely on effective mental and brain processing during the lesson, performed with the assistance of humanoid robots. The improved diagnostic ability of the CPS is a ...
Conditional Wave Function Theory: A Unified Treatment of Molecular Structure and Nonadiabatic Dynamics
(American Chemical Society, 2021-11-09)
[EN] We demonstrate that a conditional wave function theory enables a unified and efficient treatment of the equilibrium structure and nonadiabatic dynamics of correlated electron-ion systems. The conditional decomposition ...
Forces Driving the Development of Particle Morphology of Waterborne Polymer Dispersions
(Wiley, 2021-12)
[EN] Particle morphology is a key characteristic of the waterborne polymer dispersions and plenty of effort has been dedicated to understand the mechanisms controlling the development of the morphology during polymerization. ...
Mother-Child and Father-Child Relationships in Emerging Adults from Divorced and Non-Divorced Families
(MDPI, 2021-10-13)
The main aim of this study was to analyze the associations between parental divorce and interparental conflict with the quality of parent-child relationships. Specifically, we analyzed trust, communication and alienation ...
On Weighted Simpson’s 38 Rule
(MDPI, 2021-10-14)
Numerical approximations of definite integrals and related error estimations can be made using Simpson’s rules (inequalities). There are two well-known rules: Simpson’s 13 rule or Simpson’s quadrature formula and Simpson’s ...
Identification of loci associated with pathological outcomes in Holstein cattle infected with Mycobacterium avium subsp. paratuberculosis using whole-genome sequence data
(Nature Research, 2021-10-11)
[EN]Bovine paratuberculosis (PTB), caused by Mycobacterium avium subsp. paratuberculosis (MAP), is a chronic granulomatous enteritis that affects cattle worldwide. According to their severity and extension, PTB-associated ...
Infants differentially extract rules from language
(Nature Research, 2021-10-08)
[EN]Infants readily extract linguistic rules from speech. Here, we ask whether this advantage extends to linguistic stimuli that do not rely on the spoken modality. To address this question, we first examine whether infants ...
