Probing the nuclide 180W for neutrinoless double-electron capture exploration

The mass difference of the nuclides 180W and 180Hf has been measured with the Penning-trap mass spectrometer SHIPTRAP to investigate 180W as a possible candidate for the search for neutrinoless doubleelectron capture. The Q-value was measured to 143.20(27)keV. This value in combination with the calculations of the atomic electron wave functions and other parameters results in a half-life of the 0+ \rightarrow 0+ ground-state to ground-state double-electron capture transition of approximately 5\cdot10E27 years/^2

Population genomics of post-glacial western Eurasia.

Western Eurasia witnessed several large-scale human migrations during the Holocene <sup>1-5</sup> . Here, to investigate the cross-continental effects of these migrations, we shotgun-sequenced 317 genomes-mainly from the Mesolithic and Neolithic periods-from across northern and western Eurasia. These were imputed alongside published data to obtain diploid genotypes from more than 1,600 ancient humans. Our analyses revealed a 'great divide' genomic boundary extending from the Black Sea to the Baltic. Mesolithic hunter-gatherers were highly genetically differentiated east and west of this zone, and the effect of the neolithization was equally disparate. Large-scale ancestry shifts occurred in the west as farming was introduced, including near-total replacement of hunter-gatherers in many areas, whereas no substantial ancestry shifts happened east of the zone during the same period. Similarly, relatedness decreased in the west from the Neolithic transition onwards, whereas, east of the Urals, relatedness remained high until around 4,000 BP, consistent with the persistence of localized groups of hunter-gatherers. The boundary dissolved when Yamnaya-related ancestry spread across western Eurasia around 5,000 BP, resulting in a second major turnover that reached most parts of Europe within a 1,000-year span. The genetic origin and fate of the Yamnaya have remained elusive, but we show that hunter-gatherers from the Middle Don region contributed ancestry to them. Yamnaya groups later admixed with individuals associated with the Globular Amphora culture before expanding into Europe. Similar turnovers occurred in western Siberia, where we report new genomic data from a 'Neolithic steppe' cline spanning the Siberian forest steppe to Lake Baikal. These prehistoric migrations had profound and lasting effects on the genetic diversity of Eurasian populations

Semashko Nizhniy Novgorod Regional Clinical Hospital, Nizhniy Novgorod,&nbsp; Russian Federation 3JSC "Akvion", Moscow, Russian Federation Aim: to assess the effect of "Pregnoton" food supplement on pelvic venous hemodynamics in women with pelvic congestion syndrome, risk of urogenital infection recurrences during preparing for pregnancy, and sperm motility in the female genital tract. Patients and Methods: the study enrolled 87 women with recurrent cystitis (disease duration 1–5 years) secondary to pelvic congestion syndrome. Sixty-two women received "Pregnoton" to improve pelvic venous tone and prevent detrusor muscle ischemia. Later, pregnancy occurred in 20 women included in the study group. The control group included 25 women with recurrent cystitis secondary to pelvic congestion syndrome who did not receive "Pregnoton". Sperm motility was evaluated by postcoital test. In addition, pain severity, chronic cystitis recurrence rate, and pelvic venous hemodynamics were assessed. Results: women who received "Pregnoton" reported significant pain reduction during the pregnancy (from 6.3 to 3.1 points by pain scale) compared to control group women who reported more severe pain (from 5.8 to 7.8 points). In addition, improvement of pelvic venous hemodynamics (associated with further reduction in inflammation of the lower urinary tract) was detected in the study group. The therapeutic efficacy of preparation for pregnancy in women with recurrent cystitis secondary to pelvic congestion syndrome was 90% in the study group. Exacerbations of chronic cystitis were identified in two women (10%) of the study group and ten women (40%) of the control group. Conclusion: preparation for pregnancy in women with chronic recurrent cystitis and pelvic congestion syndrome using complex "Pregnoton" improves hemodynamics, lab test results, and clinical signs of bladder inflammation and reduces pain severity. Keywords: food supplement, pelvic congestion syndrome, cystitis, preparation for pregnancy, treatment. For citation: Nashivochnikova N.A., Krupin V.N., Zubova S.Yu., Leanovich V.E.

Physics book: CRYRING@ESR

The exploration of the unique properties of stored and cooled beams of highly-charged ions as provided by heavy-ion storage rings has opened novel and fascinating research opportunities in the realm of atomic and nuclear physics research. Since the late 1980s, pioneering work has been performed at the CRYRING at Stockholm (Abrahamsson et al. 1993) and at the Test Storage Ring (TSR) at Heidelberg (Baumann et al. 1988). For the heaviest ions in the highest charge-states, a real quantum jump was achieved in the early 1990s by the commissioning of the Experimental Storage Ring (ESR) at GSI Helmholtzzentrum für Schwerionenforschung (GSI) in Darmstadt (Franzke 1987) where challenging experiments on the electron dynamics in the strong field regime as well as nuclear physics studies on exotic nuclei and at the borderline to atomic physics were performed. Meanwhile also at Lanzhou a heavy-ion storage ring has been taken in operation, exploiting the unique research opportunities in particular for medium-heavy ions and exotic nuclei (Xia et al. 2002)
