この項目では、人工衛星について説明しています。人工衛星のANSにちなんで命名された小惑星については「ANS (小惑星)」をご覧ください。

ANS（英語：Astronomical Netherlands Satellite、オランダ語：Astronomische Nederlandse Satelliet、オランダ天文衛星）はオランダの紫外線・X線観測衛星。1974年8月30日、アメリカ合衆国のヴァンデンバーグ空軍基地よりスカウトロケットによって打ち上げられた。オランダ宇宙研究機関（英語版）とNASAの共同出資で行われた^[1]^[2]。

ANSはオランダ初の人工衛星で、小惑星9996 ANSはこの人工衛星にちなんで名づけられた^[5]。

初期の軌道は近地点266km、遠地点1176km、軌道傾斜角は98.0°、軌道離心率は0.064048、周期は99.2分だった^[2]。太陽同期軌道上で、姿勢制御はリアクションホイールと地球の磁場を利用したマグネティックコイルによって行われた。2つの質量物体をミッション初期に放ち、衛星の角運動量のほとんどを取り除いた。衛星の姿勢は、太陽センサー、水平感知機、恒星センサー、磁気センサーを含む、様々な方法で測定することができた^[1]。

ANSは60cm $^{2}$ の検出器によって2-30KeVのエネルギー領域でX線光子を測定することができ、銀河系内外のX線源の位置を見つけることに使用された。また、それらのスペクトルも測定し、時間的変化を観測した^[1]。X線バーストを発見し、カペラからX線を検波した^[5]。

ANSは22 cm (260 cm $^{2}$ )のカセグレイン望遠鏡によって紫外線も観測した。観測波長は150から330nm^[4]。およそ400の天体に対し18,000回以上の測定を行った^[1]。

Enculturation, perceived stress, and physical activity: implications for metabolic risk among the Yup'ik - The Center for Alaska Native Health Research Study.

Bersamin A1, Wolsko C, Luick BR, Boyer BB, Lardon C, Hopkins SE, Stern JS, Zidenberg-Cherr S.Author information 1a Center for Alaska Native Health Research , University of Alaska Fairbanks , Fairbanks , AK , USA.AbstractObjectives. American Indians and Alaska Natives (ANs) report among the lowest levels of physical activity in the USA, but there is very little systematic research examining the determinants of physical activity patterns in these populations. This study investigated the relationships between enculturation (or cultural traditionality), psychosocial stress, and physical activity in a community-based sample of Yup'ik women and men living in rural AN communities. Associations between these variables and several metabolic risk factors were also examined. Design. A sample of 488 Yup'ik participants (284 women and 204 men) from six villages in the Yukon-Kuskokwim Delta region completed a wellness survey and an array of physiological assessments [e.g., body mass index (BMI), blood pressure]. A subset of 179 participants also completed a 3-day pedometer assessment of physical activity. Results. Multivariate linear regression models indicated that participants who were more enculturated (i.e., living more of a traditional lifestyle) and who experienced lower levels of psychosocial stress were significantly more physically active. In turn, both lower levels of psychosocial stress and higher levels of physical activity were associated with lower BMI, lower percent body fat, and lower waist circumference. Conclusions. Findings underscore the importance of gaining a culturally specific understanding of physical activity patterns in indigenous groups in order to inform effective health promotion strategies.

Poor autonomic nervous system functioning during sleep in recently detoxified alcohol-dependent men and women.

de Zambotti M1, Baker FC, Sugarbaker DS, Nicholas CL, Trinder J, Colrain IM.Author information 1Center for Health Sciences, SRI International, Menlo Park, California.AbstractBACKGROUND: Alcoholism is considered an important risk factor for cardiovascular (CV) disease. Autonomic nervous system (ANS) function is a major indicator of CV health. Sleep is a suitable model to investigate ANS activity free from wake-related confounders. We investigated nighttime ANS functioning, and the relation between ANS activity and severity of alcohol dependence in chronic alcoholism.

Lemurs and macaques show similar numerical sensitivity.

Jones SM1, Pearson J, Dewind NK, Paulsen D, Tenekedjieva AM, Brannon EM.Author information 1Department of Psychology and Neuroscience, Duke University, Durham, NC, USA, Sarah.jones@snc.edu.AbstractWe investigated the precision of the approximate number system (ANS) in three lemur species (Lemur catta, Eulemur mongoz, and Eulemur macaco flavifrons), one Old World monkey species (Macaca mulatta) and humans (Homo sapiens). In Experiment 1, four individuals of each nonhuman primate species were trained to select the numerically larger of two visual arrays on a touchscreen. We estimated numerical acuity by modeling Weber fractions (w) and found quantitatively equivalent performance among all four nonhuman primate species. In Experiment 2, we tested adult humans in a similar procedure, and they outperformed the four nonhuman species but showed qualitatively similar performance. These results indicate that the ANS is conserved over the primate order.
