Z badań nad neolityzacją polski środkowej. Pozostałości osadnictwa kultury pucharów lejkowatych ze stanowiska Polesie 1, gm. Łyszkowice

The article presents the results of the study of the Funnel Beaker culture settlement at site Polesie 1, com. Łyszkowice. There have been recognised very damaged remnants of a settlement and campsites of Neolithic communities. The author of the study links them to the process of colonisation, which had started in Kujawy or eastern Wielkopolska

Środkowoneolityczne znaleziska talerzy z Niżu Polski

In this paper the author concentrates on the problem of the occurrence of clay plates within the region of the Polish Lowland. The sources are findings known from the literature as well as those excavated recently. Comparative analyses related territorially to Europe and chronologically to the period 4400-3800 BC.In this paper the author concentrates on the problem of the occurrence of clay plates within the region of the Polish Lowland.

VIRTUAL INTERACTIONS: CAN EEG HELP MAKE THE DIFFERENCE WITH REAL INTERACTION?

International audienceScience and technology progress fast, but mouse and keyboard are still used to control multimedia devices. One of the limiting factors of gesture based HCIs adoption is the detection of the user's intention to interact. This study tries to make a step in that direction with use of consumer EEG sensor headset. EEG headset records in real-time data that can help to identify intention of the user based on his emotional state. For each subject EEG responses for different stimuli are recorded. Acquiring these data allows to determine the potential of EEG based intention detection. The findings are promising and with proper implementation should allow to building a new type of HCI devices

Inner ultrahomogeneous groups

We define and study the class of inner ultrahomogeneous groups, which includes Hall's universal group and the universal locally recursively presentable group. We provide simple criteria for ample generic automorphisms, straight maximality, uniform simplicity and divisibility (all of which apply to both Hall's universal group and the universal locally recursively presentable group). We show that such groups of infinite exponent are not $\aleph_0$-saturated, their theories are not small, not rosy and have TP$_2$+SOP+IP$_n$ for all $n$. This strengthens and generalises known results about ample generic automorphisms and unstability of Hall's universal group. We also show that the exponents of finite exponent inner ultrahomogeneous groups are uniformly bounded, and we provide a series of examples of inner ultrahomogeneous groups.Comment: 31 page

Strong Lensing Analysis of the Cluster RCS0224-0002 at z=0.77z=0.77

We present a detailed mass reconstruction of the cluster RCS0224-0002 at $z=0.773$ from the strong lensing features observed with HST/WFPC2. The mass profile is reconstructed using a parametric approach. We introduce a novel method to fit extended multiple images based on the Modified Hausdorff Distance between observed arcs and the arcs reproduced by the model. We perform the detailed error analysis of the model parameter using the MCMC method. Our model reproduces all the observed strong lensing features of the RCS0224-0002 and predicts the redshift of one of the arcs systems to be $z\approx 2.65$ (the other system has an spectroscopic redshift of $z=4.87$). The reconstructed inner mass profile is well fitted by a non-singular isothermal sphere, rather than with an NFW model. Dark matter substructure, derived from the light distribution of the most luminous cluster members, is crucial for reproducing the complexity of the quadrupole image system, which could not be achieved otherwise. The reconstructed mass distribution closely follows the light, however it is significantly shifted from the X-ray emission of the gas. The mass of RCS0224-0002 derived from the lensing model, $\approx 2\times10^{14} M_\odot$ is in a very good agreement with the one obtained from the X-ray temperature measured with deep Chandra observations.Comment: 13 pages, accepted for A&
