Boundedness of spectral multipliers of generalized Laplacians on compact manifolds with boundary [PDF]

open access: yes, 2017
Consider a second order, strongly elliptic negative semidefinite differential operator $L$ (maybe a system) on a compact Riemannian manifold $\overline{M}$ with smooth boundary, where the domain of $L$ is defined by a coercive boundary condition ...

The earliest farming communities north of the Carpathians: The settlement at Gwoździec site 2.

open access: yesPLoS ONE, 2020
The appearance of the Linear Pottery Culture (LBK) on Poland territory initiated the process of neolithization in the area. However, as we will see in this article, this colonization took place later than previously thought. The stage, which in Poland is

Spikes in Quantum Regge Calculus [PDF]

open access: yes, 1997
We demonstrate by explicit calculation of the DeWitt-like measure in two-dimensional quantum Regge gravity that it is highly non-local and that the average values of link lengths $l, $, do not exist for sufficient high powers of $n$.

Soft-photon spectra and the LBK theorem

open access: yes, 2023
The study of next-to-leading-power (NLP) corrections in soft emissions continues to attract interest both in QCD and in QED. Soft-photon spectra in particular provide a clean case-study for the experimental verification of the Low-Burnett-Kroll (LBK) theorem.

From LBK to SBK: Pottery, Bones, Lithics and Houses at the Neolithic site of Hrdlovka, Czech Republic

open access: yesOpen Archaeology, 2016
The paper is focused on the period of cultural change at the turn of 6th and 5th millennia BC, when the uniform Linear Pottery Culture (LBK) occupying an extensive area disintegrated in several local groups or cultures, including the Stroked Pottery ...

Tree rings as a proxy for seasonal precipitation variability and Early Neolithic settlement dynamics in Bavaria, Germany.

open access: yesPLoS ONE, 2019
Studying the dynamic of Neolithic settlement on a local scale and its connection to climate variability is often difficult due to missing on-site climate reconstructions from natural archives.

Modelling the Neolithic dispersal in northern Eurasia

open access: yesDocumenta Praehistorica, 2004
Comprehensieve lists of radiocarbon dates from key Early Neolithic sites in Central Europe belonging to the Linear pottery Ceramic Culture (LBK) and early pottery-bearing cultures in the East European Plain were analysed with the use of the x2 test.

Twist 3 of the sl(2) sector of N=4 SYM and reciprocity respecting evolution

open access: yes, 2007
We consider the bosonic sl(2) sector of the maximally supersymmetric N=4 SYM model and show that anomalous dimension of the twist-3 single-trace composite operators built of scalar fields, recently calculated up to the four-loop order, can be generated ...

Visualization of supercritical water pseudo-boiling at Widom line crossover

open access: yesNature Communications, 2019
Supercritical water exists in gas- and liquid-like forms, but these have not been distinguished yet at the macroscale. Here the authors investigate supercritical water interacting with microporous carbon by neutron imaging, and observe the coexistence of
