Śląskie uniwersalia onimiczne na przykładzie nazw geograficznych pochodzących od nazw ptaków

2022

Przedmiotem artykułu są nazwy geograficzne Śląska pochodzące od nazw ptaków. Analizie zostały poddane polskie i niemieckie nazwy odapelatywne obiektów zamieszkanych i niezamieszkanych, a także oronimy i hydronimy. Nazwy gatunków ptaków ukazane są jako uniwersalne podstawy nazw geograficznych w obu językach. W części analitycznej opisane są poszczególne nazwy, ich lokalizacja, pierwsze zapisy, a także znaczenia realne i symboliczne ich apelatywnych podstaw nazwotwórczych. Analiza wyraźnie pokazuje, że tendencje nazewnicze w obu językach są podobne. Zdecydowana większość to nazwy topograficzne, charakteryzujące teren ze względu na występowanie na nim pewnych gatunków fauny (na przykład najczę…

Timing an Accreting Millisecond Pulsar: Measuring the Accretion Torque in IGR J00291+5934

2006

We performed a timing analysis of the fastest accreting millisecond pulsar IGR J00291+5934 using RXTE data taken during the outburst of December 2004. We corrected the arrival times of all the events for the orbital (Doppler) effects and performed a timing analysis of the resulting phase delays. In this way we have the possibility to study, for the first time in this class of sources, the spin-up of a millisecond pulsar as a consequence of accretion torques during the X-ray outburst. The accretion torque gives us for the first time an independent estimate of the mass accretion rate onto the neutron star, which can be compared with the observed X-ray luminosity. We also report a revised valu…

Notes on Selected Genera of Shore Flies (Diptera: Ephydridae), with Removals to Drosophilidae, Heleomyzidae and Milichiidae

2022

The following new taxonomic changes in nine tribes of Ephydridae are proposed: status at species level: Ditrichophora amoena (Duda, 1942); 2 resurrections from synonymy: Ptilomyia madeirensis Stuke, 2012, bona species, and P. orsovana (Enderlein, 1922), bona species; 10 new combinations: Allotrichoma communis (Malloch, 1934), comb. nov., Athyroglossa bettelai (Canzoneri, 1995), comb. nov., Ceropsilopa africana (Canzoneri & Meneghini, 1969), comb. nov., Ceropsilopa flavescens (Frey, 1958), comb. nov., Diclasiopa affinis (Tonnoir & Malloch, 1926), comb. nov., Diclasiopa flavitarsis (Tonnoir & Malloch, 1926), comb. nov., Diclasiopa senegalensis (Canzoneri, 1981), comb. nov., Ditrichophora amoe…

Katsaus 2000-luvun suomalaisiin etunimiin

2018

Kirja-arvostelu teoksesta Saarelma-Paukkala, Minna: Etunimikirja. Suomalaiset nimitrendit 2000-luvulla. SKS, 2017. 268 sivua. ISBN 978-952-222-831-4. Minna Saarelma-Paukkalan Etunimikirja jatkaa edeltäjiensä viitoittamalla tiellä. Se tarkastelee aiemmista vastaavista teoksista tuttuja teemoja 2010-luvulle päivitettyinä. Ajankohtaista etunimitutkimusta esittelevästä teoksesta jää puuttumaan historiantutkimuksen näkökulma aiempien vuosikymmenten nimistöön, samoin kuin viimeaikaisen pohjoismaisen tutkimuksen tuloksia. Omimmillaan tekijä on kuvatessaan nimipäiväkalenterin uudistamisen viimeisimpiä vaiheita, joissa hän on ollut itsekin aktiivisesti mukana, ja tästä uudistustyöstä olisi ollut kii…

Experimental on-demand recovery of entanglement by local operations within non-Markovian dynamics

2015

In many applications entanglement must be distributed through noisy communication channels that unavoidably degrade it. Entanglement cannot be generated by local operations and classical communication (LOCC), implying that once it has been distributed it is not possible to recreate it by LOCC. Recovery of entanglement by purely local control is however not forbidden in the presence of non-Markovian dynamics, and here we demonstrate in two all-optical experiments that such entanglement restoration can even be achieved on-demand. First, we implement an open-loop control scheme based on a purely local operation, without acquiring any information on the environment; then, we use a closed-loop s…

Quantum Non-Markovian Piecewise Dynamics from Collision Models

2017

Recently, a large class of quantum non-Markovian piecewise dynamics for an open quantum system obeying closed evolution equations has been introduced [B. Vacchini, Phys. Rev. Lett. 117, 230401 (2016)]. These dynamics have been defined in terms of a waiting-time distribution between quantum jumps, along with quantum maps describing the effect of jumps and the system's evolution between them. Here, we present a quantum collision model with memory, whose reduced dynamics in the continuous-time limit reproduces the above class of non-Markovian piecewise dynamics, thus providing an explicit microscopic realization.

In the present world International tourism is one of the most quickly and dynamically developing sectors of economy. In the year 2012 - for the first time in the history of humankind - international tourist arrivals exceeded one billion tourists globally; and within merely 20 years’ time, i.e. between 1995 and 2015, the number of people travelling abroad as tourists more than doubled. The phenomenon also refers to the inbound tourism in Poland - with more than 16 million international tourists who visited our country in 2015. Obviously, on the one hand, the fact is highly beneficial for the country's international prestige and economy, but on the other hand, it does create certain challenge…

CALIBRATION OF LÉVY PROCESSES USING OPTIMAL CONTROL OF KOLMOGOROV EQUATIONS WITH PERIODIC BOUNDARY CONDITIONS

2018

We present an optimal control approach to the problem of model calibration for L\'evy processes based on a non parametric estimation procedure. The calibration problem is of considerable interest in mathematical finance and beyond. Calibration of L\'evy processes is particularly challenging as the jump distribution is given by an arbitrary L\'evy measure, which form a infinite dimensional space. In this work, we follow an approach which is related to the maximum likelihood theory of sieves. The sampling of the L\'evy process is modelled as independent observations of the stochastic process at some terminal time $T$. We use a generic spline discretization of the L\'evy jump measure and selec…

On a nonlinear Schrödinger equation for nucleons in one space dimension

2021

We study a 1D nonlinear Schrödinger equation appearing in the description of a particle inside an atomic nucleus. For various nonlinearities, the ground states are discussed and given in explicit form. Their stability is studied numerically via the time evolution of perturbed ground states. In the time evolution of general localized initial data, they are shown to appear in the long time behaviour of certain cases.
