Abstract We assess the status of past and future experiments on lepton flavor violating (LFV) muon and tau decays into a light, invisible, axion-like particle (ALP), a. We propose a new experimental setup for MEG II, the MEGII-fwd, with a forward calorimeter placed downstream from the muon stopping target. Searching for μ → ea decays MEGII-fwd is maximally sensitive to LFV ALPs, if these have nonzero couplings to right-handed leptons. The experimental set-up suppresses the (left-handed) Standard Model background in the forward direction by controlling the polarization purity of the muon beam. The reach of MEGII-fwd is compared with the present constraints, the reach of Mu3e and the Belle-II reach from τ → ℓa decays. We show that a dedicated experimental campaign for LFV muon decays into ALPs at MEG II and Mu3e will be able to probe the ALP parameter space in an unexplored region well beyond the existing astrophysical constraints. We study the implications of these searches for representative LFV ALP models, where the presence of a light ALP is motivated by neutrino masses, the strong CP problem and/or the SM flavor puzzle. To this extent we discuss the majoron in low-scale seesaw setups and introduce the LFV QCD axion, the LFV axiflavon and the leptonic familon, paying particular attention to the cases where the LFV ALPs constitute cold dark matter.

Unknown Component

The accelerated expansion of the Universe is one of the main discoveries of the past decades, indicating the presence of an unknown component: the dark energy. Evidence of its presence is being gathered by a succession of observational experiments with increasing precision in its measurements. However, the most accepted model for explaining the dynamic of our Universe, the so-called Lambda cold dark matter, faces several problems related to the nature of such energy component. This has led to a growing exploration of alternative models attempting to solve those drawbacks. In this review, we briefly summarize the characteristics of a (non-exhaustive) list of dark energy models as well as some of the most used cosmological samples. Next, we discuss how to constrain each model’s parameters using observational data. Finally, we summarize the status of dark energy modeling.

Wittgenstein has often been criticized, and even dismissed, for being a patron of ordinary language, a champion of the vernacular, a defender of the status quo. One critic has written: ‘When Wittgenstein set up the actual use of language as a standard, that was equivalent to accepting a certain set up of culture and belief as a standard … It is lucky no such philosophy was thought of until recently or we should still be under the sway of witch doctors …’ In what follows I want to show just how wide of the mark criticisms of this sort are.

THIS is a progress report to the readers of Pediatrics on the status of Senator Lister Hill's "Health for Peace" bill (Senate Joint Resolution 41). This measure, which would have set up an international institute of medical research, passed the Senate May 20, 1959 with flying colors but finally was snagged in a House subcommittee through the summer of 1959. The legislation received resounding approval by the Senate, with a vote of 63 to 17. The bill proposed to organize an Institute of International Medical Research within the framework of the National Institutes of Health. A $50,000,000 annual appropriation was planned. Evidence of widespread public support for the measure was observed in the statements of authorities who spoke at the Senate hearings concerning the bill. It is of interest that no one appeared to testify against S.J. Res. 41 during the 6 days of hearings. At lease two persons participating in the hearings were members of the American Academy of Pediatrics: Dr. Martha M. Eliot, Head, Department of Maternal and Child Health, Harvard School of Public Health and Dr. Sidney Farber (Honorary Associate Member), Professor of Pathology, Harvard Medical School. Many witnesses pointed out the importance of providing support for the research activities and the training of promising scholars in other lands. On this subject, Dr. Farber had this to say: In many countries, such as Italy, the amount of research support available is so small that men of great skill and intellect are compelled to carry on only token research concerning problems which are selected because they do not require manpower, equipment, or modern research facilities.

Derivative Market

Derivatives emerged as hedging instruments out of the need to control price risk. Earlier commodity prices were the sole concern of business community, and therefore, the derivatives on commodities were the first ones to emerge. The introduction of derivatives in India can be traced out in 1875, when the Bombay Cotton Trading Association Ltd was set up for futures trading in cotton. At present the markets for derivatives have been growing at a phenomenal pace. This paper traces the growth and current position of Indian derivatives market. Since its inception in June 2000, derivatives market has exhibited exponential growth both in terms of volume and number of contract traded. The market turnover has grown from Rs.24bn in 2000-01 to Rs. 2376tn in 2018-19. The present study is an effort to demonstrate the growth and expansion of derivatives in India during the time period 2010-11 to 2018-19. It also encompasses the scope, history, concept, types and growth of financial derivatives in India and the status of Indian derivatives market vis-à-vis global derivative market.

Objective: To define a complex of changes in hematologic parameters associated with subtypes (ST) of Blastocystis sp. infections and the status of immune function in Sprague Dawley (SD) rats, and lay the foundation for Blastocystis hominis pathogenesis research. Methods: 5 isolates of ST1, ST3 and ST7 were used, including 1 isolate of ST1 from symptomatic patient, 2 isolates of ST3 and ST7 from symptomatic patients and asymptomatic carrier separately. Immune compromise model was set up using dexamethasone (DEX) and infection models with 5 isolates of ST1, ST3 and ST7, and then examined the hematologic changes post infection 15 days using fully automatic hematology analyzer sysmex xe-2100. Results: The results showed that infections of Blastocystis STs leaded to the increase of platelet indexes including MPV and PDW except ST3 isolated from asymptomatic carrier only with PDW increase and the higher values of PLT in ST7 isolated from asymptomatic carrier compared with the controls in the immune competence status (P < 0.05). However, the infections of Blastocystis ST7 isolated from symptomatic patient gave rise to higher values of WBC, LYMP, EO, MCV and RDW-SD while lower values of NEU% compared with the controls in immune compromise status (P < 0.05). Meanwhile, higher values of WBC and LYMP and lower NEUT% values were observed in ST1 infections compared with the controls (P < 0.05); lower NEUT values in ST1 infections and controls compared with ST3 and ST7 respectively were observed (P < 0.05); the infection of ST3 isolated from symptomatic patient resulted in higher values of MCV and RDW-SD while the asymptomatic isolate of ST3 only had higher RDW-SD (P < 0.05). Conclusion: The virulence of Blastocystis sp. isolated from symptomatic patient is higher than that of the identical subtype one isolated from asymptomatic carrier. The infection of ST7 isolated from symptomatic patients may result in the most distinct hematologic changes among STs, and then followed by ST1 symptomatic isolate. And the severity of Blastocystis sp. infection may be mediated by the immune status of host.

Marine Protected Areas (MPAs) are acknowledged globally as effective tools for the protection and management of the marine environment; however, to get effective results it is necessary to set up a proper and continuous mapping of the marine territory, in order to gain detailed knowledge of its different aspects. Therefore, the implementation and maintenance of a modern GIS (Geographic Information System) has become an indispensable task for the MPA of Tavolara - Punta Coda Cavallo to collect, aggregate, classify, and track the conducted mapping activities. Between 2011 and 2012 the sea bottom of the MPA was surveyed using different methods: by means of a multi-beam echo sounder and of a side scan sonar, as well as conducting fast scientific scuba divings with re-breathers and underwater position system technologies. High resolution geodatasets, characterized by a significantly high quality in representing and describing the sea bottom and its habitats, were produced in both feature (scale up to 1:1.250) and raster formats (up to 30cm/pixel for sonar images and 1m/pixel for bathymetry) and they currently constitute the basis of the MPA's GIS, including its 3D applications and its web map services for desktop and mobile devices (iPhone & Android). To update the above described geodatasets during time, acquiring new data on the conservation targets considered in monitoring activities, among which the status of P. oceanica meadows is of the most important ones, a long term mapping plan was realized on the basis of an innovative methodology elaborated by the MPA considering both the wideness of the area and the limited funds available at present. The whole MPA was divided in territorial units by means of a regular grid of square cells having a 100m side with the logic of starting the mapping activities from the mainly important areas and then to spread the surveys up to fill the whole mosaic. All the new data acquired with this methodology could then be mixed, compared and indexed within the same cell and/or in the many already available geodatases, starting from those dated 2006 having a regular grid with square cells of 500m per side.

Colored Pattern

<p><strong>Abstract.</strong> As a special part of architectural heritage, the colored pattern is not only artwork to decorate the architecture, but information reflecting specific historical era. So it has great cultural and artistic value. However, the colored pattern is one of the most sensitive types of cultural relics, which is sensitive to natural environment changes and highly vulnerable to erosion. In order to strengthen the protection of colored patterns in history architectures, it is necessary to monitor the status quo of them.</p><p>This work introduces a monitoring method of color decaying for colored patterns in architecture: set up the illuminants, adjust the illuminants, detect the color information and calculate the color difference. Based on the color difference by CIE DE2000 formula, the color decaying status of the pattern can be evaluated. The monitoring period should be at least three months.</p><p>About four years’ work has been carried out for colored patterns in the Long Corridor of the Summer Palace, and the color differences &amp;Delta;E<sub>00</sub> are about from 2 to 5, some can be over 9. In result, most colored patterns keep in good health condition. Color decaying happens every time and there are slight changes in most colored patterns. In 2nd quarter 2017, aware changes happened in nearly all the patterns. According to the color difference to evaluate the color decaying of the colored patterns, it is an efficient method to analyze the health status of colored patterns.</p>

After the liberation of Dağlık Karabağ and close vicinity from the long-standing Armenian occupation by Azerbaijan in 2020, different scenarios concerning the future of Armenia and South Caucasus have come to fore. Therefore, there should be a realistic evaluation of status quo of Armenian political elites, diasporas and Armenian economy relations before taking into account of the scenarios. It is not difficult to estimate that since the realization of optimistic scenarios need a mental transformation of Armenian political elites and diasporas that takes considerable time, they are not likely to happen let alone in the short run but even in the medium run. The aim of this paper is to investigate the status quo of Armenian political elites, diasporas, and Armenian economy relations during 1991-2019 period so as to be able to set up a scientific base on which the evaluation of scenarios concerning the future of Armenia and South Caucasus is placed. The method adopted in the paper is a descriptive one and data are collected via internet. Paper suggests that the divergence of Armenian political elites and diasporas on fundamental issues such as Armenia-diaspora relations, Armenia-Russia relations, Armenia-the West Relations and Armenia-Turkey-Azerbaijan relations blackens not only the future of Armenia but also the future of South Caucasus.
