Boosting working memory in the elderly: driving prefrontal theta–gamma coupling via repeated neuromodulation
No full textAbstract The escalating global burden of age-related neurodegenerative diseases and associated healthcare costs necessitates innovative interventions to stabilize or enhance cognitive functions. Deficits in working memory (WM) are linked to alterations in prefrontal theta–gamma cross-frequency coupling. Low-intensity transcranial alternating current stimulation (tACS) has emerged as a non-invasive, low-cost approach capable of modulating ongoing oscillations in targeted brain areas through entrainment. This study investigates the impact of multi-session peak-coupled theta–gamma cross-frequency tACS administered to the dorsolateral prefrontal cortex (DLPFC) on WM performance in older adults. In a randomized, sham-controlled, triple-blinded design, 77 participants underwent 16 stimulation sessions over six weeks while performing n -back tasks. Signal detection measures revealed increased 2-back sensitivity and robust modulations of response bias, indicating improved WM and decision-making adaptations, respectively. No effects were observed in the 1-back condition, emphasizing dependencies on cognitive load. Repeated tACS reinforces behavioral changes, indicated by increasing effect sizes. This study supports prior research correlating prefrontal theta–gamma coupling with WM processes and provides unique insights into the neurocognitive benefits of repeated tACS intervention. The well-tolerated and highly effective multi-session tACS intervention among the elderly underscores its therapeutic potential in vulnerable populations.Niedersächsische Ministerium für Wissenschaft und Kultur http://dx.doi.org/10.13039/100011937Herzzentrum Göttinge

No full textGustav Bergmann, New Foundations of Ontology
No full textThe formal ontology here presented is what we might call a typed combinatorial Meinongian mereology. Its author seeks to formulate the laws, here called ‘canons’, regulating how entities can combine together in wholes of different sorts. The method, as in Bergmann’s earlier works, involves the construction of an ideal language of such a sort that the analysis of complex wholes can be achieved by transforming our natural-language representations of reality into what we might think of as artificial characteristic maps or diagrams which allow the relevant ontological structures to be read off immediately from the symbolic representations which results. In former works Bergmann had held that the symbolic language of Principia Mathematica could serve as the appropriate diagrammatic device for the standard first-order functional calculus and develops instead a new sort diagrammatic languag

Surprisingly, we know very little about whether "Bergmann size clines" are due to a genetic response or are a consequence of phenotypic plasticity. Here, we use data on body size (mass and tarsus length) from three long-term ) study populations of great tits (Parus major) that experienced a temperature increase to examine mechanisms behind Bergmann's rule. We show that adult body mass decreased over the study period in all populations and that tarsus length increased in one population. Both body mass and tarsus length were heritable and under weak positive directional selection, predicting an increase, rather than a decrease, in body mass. There was no support for microevolutionary change, and thus the observed declines in body mass were likely a result of phenotypic plasticity. Interestingly, this plasticity was not in direct response to temperature changes but seemed to be due to changes in prey dynamics. Our results caution against interpreting recent phenotypic body size declines as adaptive evolutionary responses to temperature changes and highlight the importance of considering alternative environmental factors when testing size clines.

Molecular dynamics in a grand ensemble: Bergmann-Lebowitz model and adaptive resolution simulation
No full textThis article deals with the molecular dynamics simulation of open systems that can exchange energy and matter with a reservoir; the physics of the reservoir and its interactions with the system are described by the model introduced by Bergmann and Lebowitz (P G Bergmann and J L Lebowitz 1955 Phys. Rev. 99 578). Despite its conceptual appeal, the model did not gain popularity in the field of molecular simulation and, as a consequence, did not play a role in the development of open system molecular simulation techniques, even though it can provide the conceptual legitimation of simulation techniques that mimic open systems. We shall demonstrate that the model can serve as a tool in devising both numerical procedures and conceptual definitions of physical quantities that cannot be defined in a straightforward way by systems with a fixed number of molecules. In particular, we discuss the utility of the Bergmann-Lebowitz (BL) model for the calculation of equilibrium time correlation functions within the grand canonical adaptive resolution method (GC-AdResS) and report numerical results for the case of liquid water.Deutsche Forschungsgemeinschaft (DFG); Heisenberg grant [DE 1140/5-2]; DFG grant [DE 1140/7-1]; National High Technology Research and Development Program of China [2015AA011201]; North German Supercomputing Alliance (HLRN) [bec00100]; Heisenberg grant; [CRC 1114]SCI(E)[email protected]

Energy momentum distributions of monopole metric in teleparallel gravity
No full text32nd International Physics Congress of Turkish-Physical-Society (TPS) -- SEP 06-09, 2016 -- Bodrum, TURKEYIn this study, we investigate energy and momentum distributions of Monopole metric. For this purpose, we have used Einstein, Bergmann-Thomson and Landau-Lifshitz energy and momentum densities in Teleparallel Gravity (TG). We obtained that: (i) The solutions of Einstein and Bergmann-Thomson energy and momentum distributions give the same results but Landau-Lifshitz energy distribution does not provide same results in TG. (ii) The momentum densities of Einstein, Bergmann-Thomson and Landau-Lifshitz are vanish in TG for monopole metric. (hi) The obtained energy-momentum solutions are different from the earlier results in General Relativity (GR).Turkish Phys So

No full textRobert Leo Bergmann examines the handling of contracts with a severe initial equivalency disorder. He is based on the assumption that the legal consequences currently in force under German law do not represent a solution to the problem that is in line with interests. A comparative legal analysis shows that German law and its mandatory total nullity are isolated in Europe. On this basis, the author is looking for a new solution that does justice to both party interests and the interests of the general public. Finally, he checks whether and how the solution found can be integrated into the existing German legal system. Existing suggestions for correction of the absolute nullity stipulated in §138BGB from jurisprudence and literature are also considered and subjected to a critical assessment. -- publisher's websit
