Energy Dependance of Azimuthal Correlations (and more) in Nucleus-Nucleus Collisions at the CERN SPS

Analysing two-particle azimuthal and pseudorapidity-azimuth correlations of high-pT hadrons, experiments at the RHIC have obtained results - "the double hump", "the ridge" etc. - which provide interesting information about properties of the hot, dense medium produced in central high-energy heavy-ion collisions as well as of its interaction with products of hard scattering. However, not all of the observed effects have been fully explained by theory or models yet; such explanations are hampered in part by the lack of good reference from lower collision energies. In an attempt to further our understanding of angular dihadron correlations NA49 has, as one of the first experiments at the SPS, performed a number of scans of these correlations in Pb+Pb, Si+Si and p+p collisions at sqrt(sNN) = 17.3 GeV, as well as central Pb+Pb collisions at sqrt(sNN) = 12.3, 8.8, 7.6 and 6.3 GeV. Results of these scans have been compared to UrQMD simulations. Our experimental results from two-particle azimuthal correlations show a flattened away-side peak in central Pb+Pb (Au+Au) collisions, only weakly depends on collision energy over the whole investigated energy range - suggesting this effect originates from sources other than jet-medium interactions. This hypothesis is reinforced by good agreement with UrQMD regardless of whether jet production was enabled in the model or not. On the other hand, the amplitude of the near-side peak in central Pb+Pb (Au+Au) collisions drops visibly with decreasing collision energy, flattening out around sqrt(sNN) = 8.8 GeV and turning into a depletion below that energy - possibly an effect related to the onset of deconfinement. Finally, hints of the ridge structure can be observed in pseudorapidity-azimuth correlation functions from central Pb+Pb collisions at sqrt(sNN) = 17.3 GeV.Comment: 9 pages, 7 figures.

Energy and System-size Dependence of Two-particle Azimuthal Correlations of High-pT Charged Hadrons at the CERN SPS

Angular correlations of high-pT hadrons can serve as a probe of interactions of partons with the dense medium produced in high-energy heavy-ion collisions but other sources of such correlations exist which can be non-negligible SPS energies. In an attempt to determine the primary source, NA49 has performed an energy and system-size scan of two-particle azimuthal correlations in central Pb+Pb, Si+Si and p+p collisions at 158A GeV, as well as central Pb+Pb collisions at 20A, 30A, 40A and 80A GeV. Moreover, results at 158A GeV have been compared to UrQMD simulations.Comment: To be published in a special issue of European Physics Journal C covering results presented at the Hot Quarks 2008 conference. 4 pages, 4 figure

A Contribution to the History of the Struggle of Polish Intelligence and Counterintelligence with Soviet and Lithuanian Intelligence, Kraków 2020]

Problematyka badawcza, którą podjęli J. Widacki i A. Szuba-Boroń nie była dotąd przedmiotem zainteresowań naukowych. Jan Widacki podczas sprawowania misji dyplomatycznej w Wilnie kontynuował swoje zainteresowania naukowe, docierając do akt spraw o szpiegostwo z okresu międzywojennego. Natomiast Anna Szuba-Boroń badając m.in. akta spraw o szpiegostwo zajęła się prozą Sergiusza Piaseckiego, pisarza i byłego szpiega. Obraz pogranicza, a w nim walka wywiadów sowieckiego, litewskiego oraz polskiego kontrwywiadu to niewątpliwie interesujące tło do badań. Autorzy zdają sobie sprawę z ograniczeń badawczych, nie dotarli bowiem do spraw sądzonych w innych sądach okręgowych znajdujących się na terenie ówczesnej Rzeczypospolitej. Realnie oceniają, że wyszukanie, a także przebadanie wszystkich spraw karnych o szpiegostwo toczonych przed sądami II Rzeczypospolitej nie wydaje się dziś możliwe. Podjęty trud badawczy zasługuje na podkreślenie.As so far, the research issues that J. Widacki and A. Szuba-Boroń became interested in have not been the subject of scientific interests. During the diplomatic mission in Vilnius, J. Widacki continued his scientific interests, reaching the files of espionage cases dated from the interwar period. On the other hand, A. Szuba-Boroń examined, inter alia, the files of espionage cases, dealing with the prose of Sergiusz Piasecki, the writer and former spy. The picture of a border, and in it the struggle of Soviet, Lithuanian and Polish intelligence services is undoubtedly an interesting background for research. The authors are aware of the research limitations, as they did not reach the cases tried in other Regional Courts, located in the territory of the then – Republic of Poland. They realistically estimate that finding and examining all of the criminal espionage cases pending before the courts of the Second Polish Republic seem to be impossible today.

Physical therapies for reducing and controlling lymphoedema of the limbs.

Background Lymphoedema is the accumulation of excess fluid in the body caused by obstruction of the lymphatic drainage mechanisms. Management involves decongesting the reduced lymphatic pathways in order to reduce the size of the limb. There is a great deal of debate as to which components of a physical treatment programme are the most crucial. Objectives To assess the effect of physical treatment programmes on: volume, shape, condition and long-term control of oedema in lymphoedematous limbs; psycho-social benefits. Search strategy We searched the Cochrane Breast Cancer Group trials register (October 2007), the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 1, 2008), MEDLINE, EMBASE, CINAHL and the National Research Register (February 2008) and UnCover, PASCAL, SIGLE, reference lists produced by The British Lymphology Society and The International Society of Lymphology congress proceedings (September 2003). Selection criteria Randomised controlled clinical trials that tested physical therapies with a follow-up period of at least six months. Data collection and analysis Two blinded reviewers independently assessed trial quality and extracted data . Meta-analysis was not performed due to the poor quality of the trials. Main results Only three studies involving 150 randomised patients were included. Since none studied the same intervention it was not possible to combine the data. One crossover study of manual lymph drainage (MLD) followed by self-administered massage versus no treatment, concluded that improvements seen in both groups were attributable to the use of compression sleeves and that MLD provided no extra benefit at any point during the trial. Another trial looked at hosiery versus no treatment and had a very high dropout rate, with only 3 out of 14 participants in the intervention group finishing the trial and only 1 out of 11 in the control group. The authors concluded that wearing a compression sleeve is beneficial. The bandage plus hosiery versus hosiery alone trial, concluded that in this mixed group of participants bandage plus hosiery resulted in a greater reduction in excess limb volume than hosiery alone and this difference in reduction was maintained long-term. Authors' conclusions All three trials have their limitations and have yet to be replicated, so their results must be viewed with caution. There is a clear need for well-designed, randomised trials of the whole range of physical therapies if the best approach to managing lymphoedema is to be determined

Neuroethical Considerations Regarding Transcranial Magnetic Stimulation

Along with advances in brain technologies comes the ability to enhance the cognitive and affective states of normal people. In this essay, I examine a relatively young technology used in cognitive neuroscience called transcranial magnetic stimulation (TMS). I explain what it is, how it works and what some of its applications are. I suggest that a potential source of reservation one might have regarding brain-altering enhancement is the threat it seemingly poses to the subjective importance of mental states. I then consider the possibility of its being used as an enhancement device and question the authenticity of abilities of individuals that are enhanced by use of TMS. I conclude that judgments regarding the appropriateness of such neurocognitive enhancements should be considered on a case by case basis

RootJS: Node.js Bindings for ROOT 6

We present rootJS, an interface making it possible to seamlessly integrate ROOT 6 into applications written for Node.js, the JavaScript runtime platform increasingly commonly used to create high-performance Web applications. ROOT features can be called both directly from Node.js code and by JIT-compiling C++ macros. All rootJS methods are invoked asynchronously and support callback functions, allowing non-blocking operation of Node.js applications using them. Last but not least, our bindings have been designed to platform-independent and should therefore work on all systems supporting both ROOT 6 and Node.js. Thanks to rootJS it is now possible to create ROOT-aware Web applications taking full advantage of the high performance and extensive capabilities of Node.js. Examples include platforms for the quality assurance of acquired, reconstructed or simulated data, book-keeping and e-log systems, and even Web browser-based data visualisation and analysis.Comment: 7 pages, 1 figure.

Emily Dickinson in the Work of Polish Translators. Continuation of Research

This article deals with the Polish translation of Emily Dickinson’s poetry and correspondence. It is a continuation of the reflection in The Emily Dickinson Journal’s pages, which started in 2022. This time we present translations of Kazimiera Iłłakowiczówna, Andrzej Szuba, Krystyna Lenkowska, Ryszard Mierzejewski, Tadeusz Sławek, Teresa Pelka, Artur Międzyrzecki, Lilla Latus, Agnieszka Osiecka, Agnieszka Kreczmar and Ewa Kuryluk. We discuss a selection of Dickinson’s letters translated by Danuta Piestrzyńska. We emphasize the characteristic features of each of the discussed translations. Although Iłłakowiczówna discovered Dickinson for Polish readers, her translations are perceived as archaic. Szuba mainly translates aphoristic texts. Lenkowska makes an effort to be faithful to the original. The newest translators introduce Poles to unknown poems and make new translations of the texts previously rendered into Polish

PROCUREMENT OF ESSENTIAL DRUGS

INTRODUCTION1985 commemorated the tenth anniversary of the idea of essential drugs. It was in 1975 that the WHO Director General outlined possible new drug policies (1), and the World Health Assembly requested that advice be given to Member States on the selection and procurement of essential drugs (2). Technical work started shortly after, and the first WHO "model list" of basic, indispensable, and necessary medicines appeared in 1977 (3) as a result of which the international health community became enthusiastic. And in 1978, the Alma-Ata Conference highlighted the importance of essential drugs and their availability (4)
