We present a fully integrated cryogenic controller for electrostatically controlled quantum dots (QDs) implemented in a commercial 22-nm fully depleted silicon-on-insulator CMOS process and operating in a quantum regime. The QDs are realized in local well areas of transistors separated by tunnel barriers controlled by voltages applied to gate terminals. The QD arrays (QDA) are co-located with the control circuitry inside each quantum experiment cell, with a total of 28 of such cells comprising this system-on-chip (SoC). The QDA structure is controlled by small capacitive digital-to-analog converters (CDACs) and its quantum state is measured by a single-electron detector. The SoC operates at a cryogenic temperature of 3.4K. The occupied area of each QDA is $0.7 \times 0.4\mu \text{m}^2$ , while each QD occupies only $20 \times 80 \text{nm}^2$ . The low power and miniaturized area of these circuits are an important step on the way for integration of a large quantum core with millions of QDs, required for practical quantum computers. The performance and functionality of the CDAC are validated in a loop-back mode with the detector sensing the CDAC-compelled electron tunneling from the quantum point contact (QPC) node into the quantum structure. The position of the injected charge inside the QDA is intended to be controlled through the CDAC codes and programmable pulse width. Quantum effects are shown by an experimental characterization of charge injection and quantization into the QDA consisting of three coupled QDs. The charge can be transferred to a QD and sensed at the QPC, and this process is controlled by the relevant voltages and CDACs.

Abstract Magnetic vortices are topological spin structures frequently found in ferromagnets, yet novel to antiferromagnets. By combining experiment and theory, it is demonstrated that in a nanostructured antiferromagnetic‐ferromagnetic NiO(111)‐Fe(110) bilayer, a magnetic vortex is naturally stabilized by magnetostatic interactions in the ferromagnet and is imprinted onto the adjacent antiferromagnet via interface exchange coupling. Micromagnetic simulations are used to construct a corresponding phase diagram of the stability of the imprinted antiferromagnetic vortex state. The in‐depth analysis reveals that the interplay between interface exchange coupling and the antiferromagnet magnetic anisotropy plays a crucial role in locally reorienting the Néel vector out‐of‐plane in the prototypical in‐plane antiferromagnet NiO and thereby stabilizing the vortices in the antiferromagnet.

Katedra i Zakład Farmakologii Doświadczalnej i Klinicznej, II Wydział Lekarski z Oddziałem Anglojęzycznym, Uniwersytet Medyczny w Lublinie, Polska Streszczenie Cel pracy: Poznanie świadomości mężczyzn różnych narodowości studiujących nauki medyczne na temat samobadania piersi jako metody wczesnego wykrywania raka piersi oraz opisanie podstawowych uwarunkowań przejawianych przekonań i poglądów. Materiał i metody: Badania przeprowadzono wśród 208 studentów medycyny z Polski oraz krajów obcojęzycznych. Wszyscy respondenci studiowali na lubelskiej uczelni medycznej. Narzędziem badawczym zastosowanym w pracy był autorski kwestionariusz ankiety stworzony dla potrzeb niniejszego badania. Wyniki: Większość respondentów nie posiadało wiedzy o tym, czy kobiety z ich otoczenia wykonują samobadanie piersi. Była to najczęstsza odpowiedz zarówno wśród mężczyzn z Polski jak i z zagranicy. Niemal ¼ respondentów z Polski i jedynie 16% studentów z zagranicy było pewnych, że kobiety z ich otoczenia badają swoje piersi. Nawet 72% ogółu respondentów twierdziło zdecydowanie, że samobadanie jest ważnym aspektem profilaktyki piersi. Odpowiedziało tak 84,44% respondentów z Polski i 62,71% respondentów z zagranicy. Wnioski: Mężczyźni z Polski istotnie częściej doceniali ważność samobadania w profilaktyce nowotworu piersi aniżeli ich zagraniczni koledzy. Dodatkowo to większość Polaków wskazywała prawidłowe odpowiedzi, w zakresie zasad samobadania piersi, aniżeli mężczyźni z innych krajów. Należy podjąć działania zwiększające świadomość oraz wiedzę mężczyzn na temat wczesnej profilaktyki nowotworu piersi wśród kobiet. Słowa kluczowe: wiedza o zdrowiu, postawy, profilaktyka, świadomość; zdrowie kobiety, samobadanie piersi. Abstract Objective: To find out about the awareness among men of various nationalities studying medical sciences on breast self-examination as a method of the early detection of breast cancer and to describe the major determinants of the identified views and beliefs. Material and methods: The survey was carried out among 208 students of medicine from Poland and other countries. All the respondents studied at the Medical University of Lublin. A questionnaire prepared by the authors for the purposes of the study constituted the research instrument. Results: Most respondents did not have any knowledge on whether women in their nearest environment practiced breast self-examination. This was true both about men from Poland and from abroad. Almost one fourth of the respondents from Poland and only 16% of students from abroad were sure that women in their environment performed breast self-examination. As many as 72% of the surveyed were of the opinion that self-examination definitely is an important aspect of breast cancer prophylactics. The statement was confirmed by 84.44% of respondents from Poland and 62.71% of those from abroad. Conclusions: Men from Poland significantly more often recognised the significance of self-examination in breast cancer prophylactics than those from other countries. Furthermore, more Poles than men from other countries selected the correct answers to questions concerning breast self-examination. Therefore, measures should be taken to increase the awareness and knowledge of men about early breast cancer prophylactics among women. Key words: health knowledge, attitudes, practice, awareness, women’s health, breast self-examination.
