Correlations and fluctuations of pions at the LHC

open access: yes, 2016
The intriguing possibility of Bose-Einstein condensation of pions at the LHC is examined with the use of higher order moments of the multiplicity distribution. The scaled variance, skewness and kurtosis are calculated for the pion system.

Distance‐Dependent Energy Transfer Between Organic Fluorophores and Single‐Walled Carbon Nanotubes

open access: yesAngewandte Chemie International Edition, EarlyView.
We demonstrate that the dsDNA part adopts a perpendicular orientation to the SWCNT and present a distance‐dependent energy transfer of single fluorescent dyes to SWCNTs. Carbon nanotube energy transfer (CNET) obeys a d−5 distance dependence with a characteristic distance of 7.4 nm (± 0.7 nm) for 50 % energy transfer.

But how does it smell? An investigation of olfactory bulb size among living and fossil primates and other euarchontoglirans

open access: yesThe Anatomical Record, EarlyView.
Analysis of cranial endocast data of 181 extant and 41 fossil species from Euarchontoglires shows that there was a reduction in olfactory bulb size in Crown Primates, but that there were also subsequent reductions in various other primate clades (Anthropoidea, Catarrhini, Platyrrhini, crown Cercopithecoidea, Hominoidea).

Gauge principle and QED [PDF]

open access: yes, 2005
One of the major developments of twentieth century physics has been the gradual recognition that a common feature of the known fundamental interactions is their gauge structure.

A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

open access: yesThe Anatomical Record, EarlyView.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

Cartographic image of immaterial elements in a city on the example of city maps of Warsaw from 1641 until the end of the 19th century

open access: yesPolish Cartographical Review, 2017
The article discusses the problem of cartographic presentation of immaterial elements of city space. On the example of old city maps of Warsaw from the period between 1641 and the end of the 19th century, the image of objects and places in Warsaw is ...

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

open access: yesThe Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to
