Optimal strategy for polarization modulation in the LSPE-SWIPE experiment
Context. Cosmic microwave background (CMB) B-mode experiments are required to control systematic effects with an unprecedented level of accuracy. Polarization modulation by a half wave plate (HWP) is a powerful technique able to mitigate a large number of the instrumental systematics. Aims. Our goal is to optimize the polarization modulation strategy of the upcoming LSPE-SWIPE balloon-borne experiment, devoted to the accurate measurement of CMB polarization at large angular scales. Methods. We departed from the nominal LSPE-SWIPE modulation strategy (HWP stepped every 60 s with a telescope scanning at around 12 deg/s) and performed a thorough investigation of a wide range of possible HWP schemes (either in stepped or continuously spinning mode and at different azimuth telescope scan-speeds) in the frequency, map and angular power spectrum domain. In addition, we probed the effect of high-pass and band-pass filters of the data stream and explored the HWP response in the minimal case of one detector for one operation day (critical for the single-detector calibration process). We finally tested the modulation performance against typical HWP-induced systematics. Results. Our analysis shows that some stepped HWP schemes, either slowly rotating or combined with slow telescope modulations, represent poor choices. Moreover, our results point out that the nominal configuration may not be the most convenient choice. While a large class of spinning designs provides comparable results in terms of pixel angle coverage, map-making residuals and BB power spectrum standard deviations with respect to the nominal strategy, we find that some specific configurations (e.g., a rapidly spinning HWP with a slow gondola modulation) allow a more efficient polarization recovery in more general real-case situations. Conclusions. Although our simulations are specific to the LSPE-SWIPE mission, the general outcomes of our analysis can be easily generalized to other CMB polarization experiments

: Defines adolescents as individuals who are going through a transition period gradually achieve sexual maturity, life changes of children into adulthood and economic circumstances change from dependency to self-relative (Sarwono, 2006). Based on the projected population of Indonesia in 2000-2005, the number of adolescents aged 10-24 years about 63 million or 26.8% of the total Indonesian population where as many as 233 million of the mare students (BKKBN 2010). This study aims to reveal the knowledge a student from the University of Sam Ratulangi Manado of Timika on Reproductive Health. This research is a descriptive study with cross-sectional research methods. Sample of this research are 69 respondents. The results show that knowledge most of the respondent shave good knowledge about reproductive health (94.20%), good attitude about reproductive health (65.21%), and the action of good (65.21%). Based on the result above, Suggestions for the government or related organizations should establish rules with respect to the sexual behavior of students to improve the ethics, morality so that students are able to change the knowledge, attitude sand courses of action for the better
Hubungan Sanitasi Lingkungan Dengan Kejadian Malaria Pada Murid Sekolah Dasar Di Kabupaten Bolaang Mongondow Utara
: Malaria is a serious disease that is transmitted through the bite of anopheles mosquitoes. This disease is contagious disease that attacks all age groups that is infants, children, and adults. Malaria is transmitted from person to person Anopheles mosquitoes bringing malaria parasite or plasmodium. Environmental sanitation is efforts that conducted by individuals, communities, or the State to improve and prevent the happening health problems caused of external environmental factors. The purpose of this study to determine the relationship environmental sanitation with the incidence of malaria. This research was carried out with cross sectional method. The sample: 110 respondents drawn randomly. The independent variable in this study is environmental sanitation and dependent variable is malaria. And then, the data collected was processed with the help of computer program SPSS version 19 and analyzed with chi square test (x2) at 95% significance level (α0,05).

Meanwhile from 46 people that good environmental consists of 2 people positive malaria and 44 people is negative. The conclusion: from these data it was found that the results showed there was no relationship environmental sanitation with the incidence of malaria which the results obtained p = 0,21
Robot swarm democracy: the importance of informed individuals against zealots
Abstract: In this paper we study a generalized case of best-of-n model, which considers three kind of agents: zealots, individuals who remain stubborn and do not change their opinion; informed agents, individuals that can change their opinion, are able to assess the quality of the different options; and uninformed agents, individuals that can change their opinion but are not able to assess the quality of the different opinions. We study the consensus in different regimes: we vary the quality of the options, the percentage of zealots and the percentage of informed versus uninformed agents. We also consider two decision mechanisms: the voter and majority rule. We study this problem using numerical simulations and mathematical models, and we validate our findings on physical kilobot experiments. We find that (1) if the number of zealots for the lowest quality option is not too high, the decision-making process is driven toward the highest quality option; (2) this effect can be improved increasing the number of informed agents that can counteract the effect of adverse zealots; (3) when the two options have very similar qualities, in order to keep high consensus to the best quality it is necessary to have higher proportions of informed agents
