Isotopic substitution, which can be realized in both experiment and computer simulations, is a direct approach to assess the role of nuclear quantum effects on the structure and dynamics of matter. However, the impact of nuclear quantum effects on the structure of liquid water as probed in experiment by comparing normal to heavy water has remained controversial. To settle this issue, we employ a highly accurate machine-learned high-dimensional neural network potential to perform converged coupled cluster-quality path integral simulations of liquid HO versus DO at ambient conditions.

  • Schistosomes are skilled at evading human immunity, particularly the complement system, allowing them to survive in human blood for years; this study explores how they interact with this immune response.
  • The research shows that newly formed schistosomula are initially very vulnerable to complement attack, but they can rapidly boost their survival rate, especially when they recruit complement regulator factor H to avoid destruction.
  • The use of the drug praziquantel increases the susceptibility of schistosomula to complement-mediated killing, suggesting that further investigation into factor H's role could help develop new treatments against schistosomes.

Visual mismatch negativity is more than the sum of microsequences.

Biol Psychol

November 2024

Institute of Cognitive Neuroscience and Psychology, HUN-REN Research Centre for Natural Sciences, Magyar tudósok körútja 2, Budapest H-1117, Hungary. Electronic address:

Visual mismatch negativity (vMMN), the difference between the event-related potentials (ERPs) to repeated (standard) events and changing (deviant) events, can be caused either by diminished activity to the repeated ones (stimulus-specific adaptation, SSA), increased activity to the new ones, or both effects. To determine which of these effects contribute to the emergence of vMMN, we investigated the effect of repetition on visual ERPs. To this end, we measured electrical brain activity to task-irrelevant stimuli both in case of stimulus onset (continuously present objects, ON-events) and stimulus offset (frequently or infrequently disappearing parts of the objects, OFF-events).

Sport persistence can be coded as an indicator of sport performance and commitment, incorporating personality traits such as resilience, adaptive coping, and positive personality traits. Thus, athletes do not merely persist in sporting activities but are qualitatively committed to them. In the present research, we used a qualitative methodology to investigate the factors underlying sport persistence, using Bronfenbrenner's socio-ecological model.

We exhibit a 5-uniform hypergraph that has no polychromatic 3-coloring, but all its restricted subhypergraphs with edges of size at least 3 are 2-colorable. This disproves a bold conjecture of Keszegh and the author, and can be considered as the first step to understand polychromatic colorings of hereditary hypergraph families better since the seminal work of Berge. We also show that our method cannot give hypergraphs of arbitrary high uniformity, and mention some connections to panchromatic colorings.

The first search for soft unclustered energy patterns (SUEPs) is performed using an integrated luminosity of 138  fb^{-1} of proton-proton collision data at sqrt[s]=13  TeV, collected in 2016-2018 by the CMS detector at the LHC. Such SUEPs are predicted by hidden valley models with a new, confining force with a large 't Hooft coupling. In events with boosted topologies, selected by high-threshold hadronic triggers, the multiplicity and sphericity of clustered tracks are used to reject the background from standard model quantum chromodynamics.

MTA-ELTE "Lendület" (Momentum) Social Minds Research Group, Institute of Psychology, ELTE Eötvös Loránd University, Izabella Street 46, Budapest, 1064, Hungary.

Humans demonstrate spontaneous sensitivity to other people's perspectives on object identities in online tasks. Evidence shows that this not only involves representing the mere discrepancy between perspectives, but the content of such perspectives as well (level-2 perspective taking/L2PT). However, this evidence comes from studies using culturally grounded symbols which leaves open the possibility that having extensive, easily accessible background knowledge about an object is necessary for the L2PT effect.
