Probing the CP nature of the Higgs boson at linear colliders with tau spin correlations; the case of mixed scalar--pseudoscalar couplings

The prospects for the measurement of the pseudoscalar admixture in the h-tau-tau coupling to a Standard Model Higgs boson of 120 GeV mass are discussed in a quantitative manner e+ e- collisions of 350 GeV centre-of-mass energy. Specific angular distributions in the h --> tau tau; tau --> rho nu decay chain can be used to probe mixing angles of scalar--pseudoscalar h-tau-tau couplings. In the discussion of the feasibility of the method, assumptions on the properties of a future detector for an e+ e- linear collider such as TESLA are used. The Standard Model Higgsstrahlung production process is taken as an example. For the expected performance of a typical Linear Collider set-up, the sensitivity of a measurement of the scalar--pseudoscalar mixing angle turned out to be 6 degree. It will be straightforward to apply our results to estimate the sensitivity of a measurement, in cases another scenario of the Higgs boson sector (Standard Model or not) is chosen by nature. The experimental error of the method is expected to be limited by the statistics.Comment: 10 pages, 7 figures, LaTeX. Corrections of published version include

End‑of‑life care for patients with advanced lung cancer and chronic obstructive pulmonary disease: Survey among Polish pulmonologists

Copyright by Medycyna Praktyczna, Kraków 2019 INTRODUCTION There is evidence that people with nonmalignant disease receive poorer end‑of‑life (EOL) care compared with people with cancer. OBJECTIVES The aim of the study was to assess the selected aspects of symptomatic treatment and communication between physicians and patients diagnosed with either advanced chronic obstructive pulmonary disease (COPD) or lung cancer. METHODS A questionnaire survey was conducted online among members of the Polish Respiratory Society. RESULTS Properly completed questionnaires were returned by 174 respondents (27.2% of those proved to be contacted by email). In COPD, 32% of respondents always or often used opioids in chronic breathlessness and 18.3% always or often referred patients to a palliative care (PC) specialist. Nearly 80% of the respondents claimed that bedside discussions on EOL issues with people with COPD are essential, although only 20% would always or often initiate them. In people with lung cancer, opioids were routinely used for relief of chronic breathlessness by 80% of physicians; 81.7% referred patients to a PC specialist. More than half of the respondents always or often discussed EOL issues only with the patient’s caregivers or relatives. Younger physicians, those at an earlier stage of their career, those caring for higher numbers of patients with lung cancer, and those who were better acquainted with Polish Respiratory Society recommendations for PC in chronic lung diseases seemed to provide better EOL care for COPD patients. CONCLUSIONS Patients with COPD, as compared with patients with lung cancer, were less frequently treated with opioids to relieve chronic breathlessness or referred for a PC consultation. Discussing the EOL issues with a patient was generally found challenging by physicians, and most often pursued with caregivers instead. The COPD recommendations on PC may prove helpful in providing better EOL care by pulmonologists

Modeling and simulation IoT network in SenseSim simulator

W pracy przedstawiono model symulacyjny sieci sensorowej oraz IoT, będące podstawą dla budowy symulatora SenseSim. Pozwala on na zbudowanie heterogenicznej sieci (lub wielu sieci), której sensory obserwują zmieniające się w czasie zjawiska. Zaletami proponowanego modelu są: możliwość szerokiej konfiguracji węzłów, które posiadać mogą wiele zdolności do obserwacji środowiska, oraz łatwa konfigurowalność algorytmów trasowania i komunikacji bezprzewodowej. Symulator zbudowany w oparciu o przedstawiony model będzie również umożliwiał modyfikację zachowania sensorów poprzez ich makroprogramowanie. Dodatkowo proponowane jest rozszerzenie symulatora o modelowanie wielorozdzielcze.The paper presents a simulation model of both sensor network and IoT as a base for the simulator SenseSim. SenseSim allows one to build a heterogeneous network (or networks), whose sensors observe the time-varying phenomena. The advantages of the proposed model are: the possibility of a wide configuration of nodes that can have a lot of capacity for environmental monitoring and easy configurability of both routing algorithms and wireless communications. The simulator built on the presented model will also allows one to modify the behavior of sensors through their macroprogramming. In addition, it is proposed to extend the simulator for multiresolution modelling
