In the paper we investigate properties of maximum pseudo-likelihood estimators for the copula density and minimum distance estimators for the copula. We derive statements on the consistency and the asymptotic normality of the estimators for the parameters.
We investigate the regularity of semipermeable surfaces along barrier solutions without the assumption of smoothness of the right-hand side of the differential inclusion. We check what can be said if the assumptions concern not the right-hand side itself but the cones it generates. We examine also the properties of families of sets with semipermeable boundaries.
We introduce a weakened form of regularity, the so called semiregularity, and we show that if every diagonal subalgebra of $\mathcal A \times \mathcal A$ is semiregular then $\mathcal A$ is congruence modular at 0.
We prove that a finite von Neumann algebra A is semisimple if the algebra of affiliated operators U of A is semisimple. When A is not semisimple, we give the upper and lower bounds for the global dimensions of A and U . This last result requires the use of the Continuum Hypothesis.
V nálezovém souboru z tvrze Semonice u Jaroměře byl identifikován pár železných nákončí tkalcovské rozpínky, dosud považovaných za atypické šipky. Nález, datovaný průvodním materiálem do počátku 14. stol., je nejstarším hmotným dokladem horizontálního tkalcovského stavu a s ním spojené technologie tkaní na území ČR. Příspěvek jej uvádí do kontextu archeologických (zejména švýcarských) a dalších pramenů, otevírá otázku textilní produkce v hospodářství feudálních sídel, pokouší se o rekapitulaci zpráv o výzkumu z r. 1896, interpretaci tehdy odkryté situace a datování evropsky významného nálezového celku. and A pair of iron loom temple ends, previously considered as atypical arrows, was identified in the collection of finds from the Semonice fortified manor near Jaroměř (Eastern Bohemia). The find, dated by means of accompanying material to the beginning of the 14th century, is the oldest evidence of a horizontal loom and the related weaving technology within the territory of the Czech Lands. The paper puts the find in the context of archaeological (especially Swiss) and other sources, opens the question of textile production in the economy of feudal estates and attempts to review a research report from 1896 offering an interpretation of the context uncovered at the time and a dating of a find assemblage with European significance.
This issue also brings an interview with Dr. Vilém Neděla, the head of Environmental Electron Microscopy of the Institute of Scientific Instruments of the CAS on the Quanta 650 FEG scanning electron microscope (SEM), which is used for high-resolution imaging and semi-quantitative X-ray microanalysis of both conductive and non-conductive specimens at nanometer resolution. and Magdaléna Selingerová.
