A crossed vortex bottle beam trap for single-atom qubits

We demonstrate trapping and quantum state control of single Cesium atoms in a 532 nm wavelength bottle beam trap. The three dimensional trap is formed by crossing two unit charge vortex beams. Single atoms are loaded with 50% probability directly from a magneto-optical trap. We achieve a trapping lifetime of up to 6 s, and demonstrate fast Rabi oscillations with a coherence time of $T_2\sim 43 \pm 9\rm ms$.Comment: 5 figures, minor edits to text and figures, to appear opt. let

СОСТОЯНИЕ ОРГАЗМИЧЕСКОЙ ФУНКЦИИ ПОСЛЕ РАДИКАЛЬНОЙ ПРОСТАТЭКТОМИИ

Objective: to study orgasmic function (OF) in patients undergoing radical prostatectomy (RPE).Subjects and methods. Seventy-nine patients who had undergone RPE for locally advanced prostate cancer without hormone and radiation therapies were examined. The patients’ mean age was 59.3 years. The mean EF-IIEF domain score was 24.4. OF was estimated by IIEF question 10 and the authors’ questionnaire. The Spearman rank correction coefficient and Mann-Whitney U-Wilcoxon tests were used.Results. After RPE, there was a reduction in the mean IIEF question 10 score from 3.9 (confidence interval 3.7–4.1) to 3.3 (3–3.5) (p = 0.000). The following changes were found in orgasm intensity: no changes in 43 %, mild worsening in 42 %, severe worsening in 8 %, and enhancement in 4 %; orgasm could not be achieved in 4 % of the patients. Pain usually of low intensity was reported by 8.8 %. The poor factors for preserving OF were its low baseline level, elderly age, or severe post-RPE erectile dysfunction.Conclusion. There were significant OF changes after RPE, which should be kept in mind while treating this category of patients.Цель исследования – изучение состояния оргазмической функции (ОФ) у больных, перенесших радикальную простатэктомию (РПЭ).Материалы и методы. Обследованы 79 пациентов, которым была выполнена РПЭ по поводу локализованного рака предстательной железы без проведения гормональной и лучевой терапии. Средний возраст больных составил 59,3 года. Средний балл по опроснику EF-IIEF был равен 24,4. Оценку ОФ выполняли по вопросу № 10 IIEF и собственному опроснику. Использовали ранговую корреляцию по Спирмену и -тесты Вилкоксона и Манна–Уитни.Результаты. После осуществления РПЭ отмечено снижение среднего балла по вопросу № 10 IIEF с 3,9 (доверительный интервал 3,7–4,1) до 3,3 (3–3,5), p = 0,000. Выявлены следующие изменения интенсивности оргазма: отсутствие изменений — в 43 %, легкое ухудшение — в 42 %, выраженное ухудшение — в 8 %, усиление — в 4 % случаев; 4 % больных не смогли достичь оргазма. Боли, обычно малой интенсивности, отметили 8,8% пациентов. Неблагоприятными факторами для сохранения ОФ были исходно низкий ее уровень, пожилой возраст, возникшая после РПЭ тяжелая эректильная дисфункция

OPTIMIZATION OF PHARMACEUTICAL CARE FOR JUVENILE RHEUMATOID ARTHRITIS AT THE REGIONAL LEVEL

Clinical practice and content analysis of scientifi c literature indicate that for treatment of the immune-infl amatory disease called juvenile rheumatoid arthritis (JRA), the use of only basic medicines (BM) is not suffi cient.The aim of the study is the organization of pharmacotherapy of JRA patients by genetically engineered biological preparations (GEBP), affecting the immune processes of the body directly.Materials and methods: the theory of marketing, content analysis, the ABC-analysis, sociological survey, pharmacoeconomic methods.Results and discussion. Depending on the individual characteristics of patients, the clinical picture of the disease can manifest itself in different ways, which requires justifi cation of the necessary schemes of GEBP pharmacotherapy at each stage of the carried out treatment. In the course of studying the organization of pharmaceutical assistance at the inpatient stage, we carried out a content analysis of 175 medical records of the patients (aged 2–17 years old) of the cardiologic department of Irkutsk State Children’s Clinical Hospital, in the dynamics of a few years (2015–2017), and the expert assessment of the degree of GEBP demand was carried out by the doctors. The analysis of the pharmacotherapy has shown that GEBP is used as monotherapy in patients with intolerance to basic medicines or to combinations with basic medicines. It is irrational to start the GIBP treatment immediately because of possible side effects and their high cost. According to the content analysis of the reports of the regional Ministry of Health on preferential drug provision of handicapped children, both in hospital and at outpatient treatment stage, the pharmacotherapy schemes including Adalimumab, Abatacept, Infl iximab, Tocilizumab, Etanercept are most in demand.Conclusion. The study of the organization of GEBP pharmacotherapy, the expert assessment carried out by the doctors, the results of the marketing analysis of the regional pharmaceutical market made it possible to substantiate and propose a rational assortment portfolio of this group of medicines for treatment of various JRA options, taking into account the price component in the Irkutsk region. The obtained results can be used for the formation of the medicinal budget of medical organizations in the region

A quantum memory with telecom-wavelength conversion

In a fibre-based quantum information network, telecom-wavelength transmission between quantum memory elements is required to minimize absorption. Owing to the paucity of suitable ground-state atomic transitions, a quantum memory interfaced with telecom light has not been previously realized. We report its demonstration by converting to telecom wavelength near-infrared light emitted on a ground-state transition. The conversion is achieved with a diamond configuration of atomic transitions, in an optically thick gas of cold rubidium. The quantum memory is also realized with cold rubidium, but confined in an optical lattice to suppress motional dephasing on a submillisecond timescale. We observe quantum memory lifetimes in excess of 0.1?s by laser compensation of the lattice light shifts that limited the previous generation of atomic memory to 7?ms. By measuring quantum correlations of light fields before and after telecom down-conversion, transmission and up-conversion, we demonstrate a basic memory element for a scalable, long-distance quantum networ
