The effect of chromatic aberration in process lenses on the copying of reflection halftone dots

A method for evaluation of copydot quality is determined. This method is applied to the problem of determining the relative copydot quality of two films of different spectral sensitivities, while using two process lenses with measureable amounts of chromatic aberration

Futurismo arcaizante: descolonización y anarcofeminismo en De cuando en cuando Saturnina

Partiendo de la descripci&oacute;n de la novela De cuando en cuando Saturnina &nbsp;(Alison Spedding, 2004) como &ldquo;ciencia ficci&oacute;n originaria anarco&ndash;feminista&rdquo; declarada&nbsp; en&nbsp; la&nbsp; contratapa&nbsp; de&nbsp; la&nbsp; primera&nbsp; edici&oacute;n,&nbsp; el&nbsp; presente trabajo propone una lectura entrecruzada de estos cuatro ejes (futurismo, l&oacute;gica aymara, anarquismo y feminismo). Leo en la estructura de la &ldquo;historia oral del futuro&rdquo; una voluntad cr&iacute;tica que reh&uacute;ye cualquier tentaci&oacute;n de ver la reinstauraci&oacute;n de Qullasuyu &nbsp;como &nbsp;horizonte ut&oacute;pico de una sociedad id&iacute;lica, pero que al mismo tiempo apuesta a una descolonizaci&oacute;n radical de Bolivia anclada &nbsp;en una &nbsp;&nbsp;gram&aacute;tica &nbsp;&nbsp;cultural &nbsp;&nbsp;aut&oacute;noma &nbsp;y &nbsp;propia. &nbsp;As&iacute;, &nbsp;la novela despliega una visi&oacute;n cr&iacute;tica no s&oacute;lo de la colonialidad a la que ha estado sometida la cultura aymara &nbsp;sino &nbsp;tambi&eacute;n &nbsp;de &nbsp;&eacute;sta misma y de sus desaf&iacute;os internos, particularmente en relaci&oacute;n a jerarqu&iacute;as de g&eacute;nero. Drawing on the description of De cuando en cuando Saturnina by Alison Spedding as &ldquo;native anarco&ndash;feminist science fiction&rdquo; announced on the back cover of its first edition (2004), this article proposes an interconnected reading of these four axes (futurism, Aymara logic, anarchism, and feminism). I argue that the structure of this &ldquo;oral history of the future&rdquo; conveys&nbsp; a critical resolve to avoid positing the reinstatement of Qullasuyu as the utopic horizon of an idyllic society, while the text as a whole remains &nbsp;committed to a radical decolonization of Bolivia anchored in an autonomous cultural grammar. In this sense, the novel offers a critical vision not only of the coloniality that Aymara culture has endured but also of certain challenges internal to Aymara society itself, particularly in regards to gender hierarchy.</div

Self-Objectification and Self-Surveillance in African American and Latina Girls: Links to Body Dissatisfaction and Self-Worth

Drawing on a sample of low-income African American and Latina girls, the goal of the present investigation was to examine the relevance of self-objectification and self-surveillance to body dissatisfaction and self-worth. Body mass index (BMI), ethnicity, and perceived athletic competence were examined as moderators of these relations. Participants were 10- to 14-year-old African American and Latina girls recruited from a summer camp targeting low-income, urban girls. Surveys that include measures of self-objectification, self-surveillance, body dissatisfaction, self-worth, and perceived athletic competence were individually administered to participants by a research assistant. Height and weight were measured to calculate BMI. Ethnicity information was obtained from surveys completed by parents. Results indicated that self-objectification and self-surveillance were related, and older girls reported higher levels of each. No main effects of self-objectification were found, however, higher levels of self-surveillance were associated with lower self-worth. Among African American girls with higher BMI, self-objectification was associated with less body dissatisfaction. Among Latina girls with higher perceived athletic competence, higher self-objectification was associated with lower self-worth. Findings indicate that self-objectification and self-surveillance are indeed experienced by low-income, ethnic minority girls and increase across the transition to adolescence. Self-surveillance may be particularly important to address in interventions targeting self-worth of ethnic minority girls. Finally, results suggest the importance of ethnicity, BMI, and perceived athletic competence in understanding how self-objectification and self-surveillance relate to well-being among ethnic minority girls

Precision mass measurements of magnesium isotopes and implications on the validity of the Isobaric Mass Multiplet Equation

If the mass excess of neutron-deficient nuclei and their neutron-rich mirror partners are both known, it can be shown that deviations of the Isobaric Mass Multiplet Equation (IMME) in the form of a cubic term can be probed. Such a cubic term was probed by using the atomic mass of neutron-rich magnesium isotopes measured using the TITAN Penning trap and the recently measured proton-separation energies of $^{29}$Cl and $^{30}$Ar. The atomic mass of $^{27}$Mg was found to be within 1.6$\sigma$ of the value stated in the Atomic Mass Evaluation. The atomic masses of $^{28,29}$Mg were measured to be both within 1$\sigma$, while being 8 and 34 times more precise, respectively. Using the $^{29}$Mg mass excess and previous measurements of $^{29}$Cl we uncovered a cubic coefficient of $d$ = 28(7) keV, which is the largest known cubic coefficient of the IMME. This departure, however, could also be caused by experimental data with unknown systematic errors. Hence there is a need to confirm the mass excess of $^{28}$S and the one-neutron separation energy of $^{29}$Cl, which have both come from a single measurement. Finally, our results were compared to ab initio calculations from the valence-space in-medium similarity renormalization group, resulting in a good agreement.Comment: 7 pages, 3 figure

Coping with brief periods of food restriction: mindfulness matters

The obesity epidemic had spawned considerable interest in understanding peoples' responses to palatable food cues that are plentiful in obesogenic environments. In this paper we examine how trait mindfulness of older, obese adults may moderate brain networks that arise from exposure to such cues. Nineteen older, obese adults came to our laboratory on two different occasions. Both times they ate a controlled breakfast meal and then were restricted from eating for 2.5 h. After this brief period of food restriction, they had an fMRI scan in which they were exposed to food cues and then underwent a 5 min recovery period to evaluate brain networks at rest. On one day they consumed a BOOST® liquid meal prior to scanning, whereas on the other day they only consumed water (NO BOOST® condition). We found that adults high in trait mindfulness were able to return to their default mode network (DMN), as indicated by greater global efficiency in the precuneus, during the post-exposure rest period. This effect was stronger for the BOOST® than NO BOOST® treatment condition. Older adults low in trait mindfulness did not exhibit this pattern in the DMN. In fact, the brain networks of those low on the MAAS suggests that they continued to be pre-occupied with the elaboration of food cues even after cue exposure had ended. Further work is needed to examine whether mindfulness-based therapies alter brain networks to food cues and whether these changes are related to eating behavior

Auditory enhancement of visual temporal order judgment

Abstract: Although numerous studies have shown that response times can be speeded by the presentation of multisensory stimuli, here we show that such speeding can be seen even when the second sensory channel fails to provide any task-relevant (i.e. redundant) information, and where cueing appears an unlikely explanation. Study participants performed a visual temporal order judgment task in the presence of task uninformative auditory cues, with the latter sound delayed relative to the latter visual cue. Responses were maximally speeded when the auditory stimulus was delayed by a short time (i.e. 100 ms) relative to the second visual target. These results illustrate a unique form of temporal benefit underlying a multisensory interaction, and form the basis for a novel explanation of these perceptual enhancements

Spontaneous Transformation of Murine Oviductal Epithelial Cells: A Model System to Investigate the Onset of Fallopian-Derived Tumors

High-grade serous carcinoma (HGSC) is the most lethal ovarian cancer histotype. The fallopian tube secretory epithelial cells (FTSECs) are a proposed progenitor cell type. Genetically altered FTSECs form tumors in mice; however, a spontaneous HGSC model has not been described. Apart from a subpopulation of genetically predisposed women, most women develop ovarian cancer spontaneously, which is associated with aging and lifetime ovulations. A murine oviductal cell line (MOELOW) was developed and continuously passaged in culture to mimic cellular aging (MOEHIGH). The MOEHIGH cellular model exhibited a loss of acetylated tubulin consistent with an outgrowth of secretory epithelial cells in culture. MOEHIGH cells proliferated significantly faster than MOELOW, and the MOEHIGH cells produced more 2D foci and 3D soft agar colonies as compared to MOELOW. MOEHIGH were xenografted into athymic female nude mice both in the subcutaneous and the intraperiteonal compartments. Only the subcutaneous grafts formed tumors that were negative for cytokeratin, but positive for oviductal markers such as oviductal glycoprotein 1 and Pax8. These tumors were considered to be poorly differentiated carcinoma. The differential molecular profiles between MOEHIGH and MOELOW were determined using RNA-Seq and confirmed by protein expression to uncover pathways important in transformation, like the p53 pathway, the FOXM1 pathway, WNT signaling, and splicing. MOEHIGH had enhanced protein expression of c-myc, Cyclin E, p53 and FOXM1 with reduced expression of p21. MOEHIGH were also less sensitive to cisplatin and DMBA, which induce lesions typically repaired by base-excision repair. A model of spontaneous tumorogenesis was generated starting with normal oviductal cells. Their transition to cancer involved alterations in pathways associated with high-grade serous cancer in humans
