description: Microwave Kinetic Inductance Detectors (MKIDs) are the most attractive radiation detectors for far-infrared and sub-mm astronomy: They combine ultimate sensitivity with the possibility to create very large detector arrays, in excess of 10 000 pixels. This is possible by reading-out the arrays using RF frequency division multiplexing, which allows multiplexing ratios in excess of 1000 pixels per readout line. We describe a novel readout system for large arrays of MKIDs, operating in a 2 GHz band in the 4-8 GHz range. The readout, which is a combination of a digital front- and back-end and an analog up- and down-converter system, can read out up to 4000 detectors simultaneously with 1 kHz datarate. The system achieves a readout noise power spectral density of -98 dBc/Hz while reading 1000 carriers simultaneously, which scales linear with the number of carriers. We demonstrate that 4000 state-of-the-art Aluminium-NbTiN MKIDs can be read out without deteriorating their intrinsic performance.

description: OBJECTIVE: To identify risk factors for maternal morbidity after previable prelabor rupture of membranes (PROM). METHODS: We conducted a case-control study of singleton and twin pregnancies complicated by previable PROM (14.0-22.9 weeks of gestation) at a single tertiary care referral institution, 2000-2015. Pregnancies complicated by fetal anomalies, previable PROM within 2 weeks of chorionic villus sampling or amniocentesis, and those with contraindications to expectant management (eg, chorioamnionitis) were excluded. Cases were women with the primary outcome of composite maternal morbidity (defined as having at one or more of the following: sepsis, intensive care unit admission, acute renal insufficiency, uterine curettage, hysterectomy, deep vein thrombosis, pulmonary embolus, blood transfusion, readmission, or maternal death). Controls were women without the primary composite morbidity. Bivariate analysis compared demographic, clinical, and management characteristics of women in the case group and those in the control group. Multivariable logistic regression models were developed to quantify the association between maternal characteristics and composite severe maternal morbidity. RESULTS: During the study period, 174 women presented with by previable PROM and were candidates for expectant management. Sixty-five (37%) women opted for immediate delivery; 109 (63%) elected expectant management. Twenty-five of 174 (14%) experienced one or more components of the composite maternal morbidity (cases) and were compared with 149 (86%) women in the control group. Women in the case group were more not more likely to elect expectant management (68% compared with 59%, P=.40), but were more likely to be aged 35 years or older (40% compared with 14%, P=.002) or to be carrying twins (52% compared with 16%, P<.01). In the regression model, twin gestation and age 35 years or older were both significantly associated with increased odds of composite maternal morbidity (odds ratio [OR] 5.62, 95% confidence interval [CI] 2.21-14.3 and OR 4.00, 95% CI 1.48-10.8, respectively). CONCLUSION: Antenatal counseling of women with previable PROM should include that one in seven women experience significant morbidity. Although expectant management was not associated with increased risk in this cohort, women with twins or those aged 35 years or older were at substantially increased risk.
17-alpha hydroxyprogesterone caproate for preterm birth prevention: Where have we been, how did we get here, and where are we going?

Year: 2017

description: Prematurity is a major public health problem in the United States and worldwide. Women with a history of a previous preterm birth are at high risk for recurrence. Progesterone is a key hormone involved in pregnancy maintenance. In general, progesterone is thought to maintain pregnancy through several closely linked mechanisms: (1) promotion of uterine quiescence, (2) inhibition of pro-inflammatory cells, and (3) immunosuppressive action. 17-Alpha hydroxyprogesterone caproate is currently the only medication approved to prevent recurrent preterm birth. The purpose of this review is to discuss the history of 17-alpha hydroxyprogesterone caproate use for recurrent preterm birth prevention, the rationale behind 17-alpha hydroxyprogesterone caproate administration, and current evidence-based indications for 17-alpha hydroxyprogesterone caproate use.

description: Samples of early-type galaxies show a correlation between stellar velocity dispersion and the stellar initial mass function (IMF) as inferred from gravity-sensitive absorption lines in the galaxies' central regions. To search for spatial variations in the IMF, we have observed two early-type galaxies with Keck/LRIS and measured radial gradients in the strengths of absorption features from 4000-5500 Å$\,$ and 8000-10,000 Å. We present spatially resolved measurements of the dwarf-sensitive spectral indices NaI (8190 Å) and Wing-Ford FeH (9915 Å), as well as indices for species of H, C$_2$, CN, Mg, Ca, TiO, and Fe. Our measurements show a metallicity gradient in both objects, and Mg/Fe consistent with a shallow gradient in α-enhancement, matching widely observed trends for massive early-type galaxies. The NaI index and the CN$_1$ index at 4160 Å$\,$ exhibit significantly steeper gradients, with a break at $r \sim 0.1 r_{\rm eff}$ ($r \sim 300$ pc). Inside this radius NaI strength increases sharply toward the galaxy center, consistent with a rapid central rise in [Na/Fe]. In contrast, the ratio of FeH to Fe index strength decreases toward the galaxy center. This behavior cannot be reproduced by a steepening IMF inside $0.1 r_{\rm eff}$ if the IMF is a single power law. While gradients in the mass function above $\sim 0.4 M_\odot$ may occur, exceptional care is required to disentangle these IMF variations from the extreme variations in individual element abundances near the galaxies' centers.

Racial and ethnic differences in preterm birth: A complex, multifactorial problem
Creators: name: Manuck, T.A.
Publisher: name: W.B. Saunders
Year: 2017

description: Preterm birth remains the leading cause of morbidity and mortality among nonanomalous neonates, and is a major public health problem. Non-Hispanic black women have a 2-fold greater risk for preterm birth compared with non-Hispanic white race. The reasons for this disparity are poorly understood and cannot be explained solely by sociodemographic factors. Underlying factors including a complex interaction between maternal, paternal, and fetal genetics, epigenetics, the microbiome, and these sociodemographic risk factors likely underlies the differences between racial groups, but these relationships are currently poorly understood. This article reviews the epidemiology of disparities in preterm birth rates and adverse pregnancy outcomes and discuss possible explanations for the racial and ethnic differences, while examining potential solutions to this major public health problem.

description: Based on a recent photometric redshift galaxy catalogue, we have searched for galaxy clusters in the Stripe~82 region of the Sloan Digital Sky Survey by applying the Adami & MAzure Cluster FInder (AMACFI). Extensive tests were made to fine-tune the AMACFI parameters and make the cluster detection as reliable as possible. The same method was applied to the Millennium simulation to estimate our detection efficiency and the approximate masses of the detected clusters. Considering all the cluster galaxies (i.e. within a 1 Mpc radius of the cluster to which they belong and with a photoz differing by less than 0.05 from that of the cluster), we stacked clusters in various redshift bins to derive colour-magnitude diagrams and galaxy luminosity functions (GLFs). For each galaxy with absolute magnitude brighter than -19.0 in the r band, we computed the disk and spheroid components by applying SExtractor, and by stacking clusters we determined how the disk-to-spheroid flux ratio varies with cluster redshift and mass. We detected 3663 clusters in the redshift range 0.15

AT THE WATER�S EDGE? ITALIAN POLITICAL PARTIES AND MILITARY OPERATIONS ABROAD
Creators: name: VIGNOLI, VALERIO
Publisher: name: Universit� degli Studi di Milano
Year: 2020

description: For various decades, scholars in the fields of International Relations (IR) and Foreign Policy Analysis (FPA) have neglected the relevance of political parties as crucial actors in the study of states? foreign and security policy. However, recently, academic debate on the connection between parties and foreign policy has significantly grown along three lines: party contestation across ideological cleavages, the impact of coalition politics and junior coalition partners, and the constraining power of legislatives, also considered as aggregations of parties. Contributing to this flourishing research agenda, this PhD dissertation explores how Italian parties positioned and interacted on Military Operations Abroad (MOA) during the so-called ?Second Republic? (1994-2013). In other words, it fundamentally aims to scrutinize and explain party support for MOAs in Italy. The relevance of the Italian case lies in the country?s extraordinary commitment to military interventions after the end of the Cold War and the relatively high extent of fragmentation in its party system. Through the use of quantitative and qualitative data and methods, this PhD thesis highlights a series of findings with considerable implications for the study of party politics of troop deployments in Italy and in other Western democracies. Among them, three deserve particular attention. First, in line with existing studies, the presence of a centrist and bipartisan consensus on this issue based on a shared humanitarian narrative is confirmed. Secondly, party contestation across the left-right axis is decisively affected by a number of domestic and external factors, namely party affiliation to the cabinet, law-making procedures and the international legitimation of the specific operation. Thirdly, the salience attributed to opposition to MOAs among radical parties diverges according to their ideological leaning: extreme left parties rooted their scepticism on a deeply entrenched pacifist sentiment while the far right and autonomist Lega Nord had a more instrumental approach to the issue.

description: Multiple terrestrial and space-based telescopes have been proposed for detecting and tracking near-Earth objects (NEOs). Detailed simulations of the search performance of these systems have used complex computer codes that are not widely available, which hinders accurate cross-comparison of the proposals and obscures whether they have consistent assumptions. Moreover, some proposed instruments would survey infrared (IR) bands, whereas others would operate in the visible band, and differences among asteroid thermal and visible light models used in the simulations further complicate like-to-like comparisons. I use simple physical principles to estimate basic performance metrics for the ground-based Large Synoptic Survey Telescope and three space-based instruments - Sentinel, NEOCam, and a Cubesat constellation. The performance is measured against two different NEO distributions, the Bottke et al. distribution of general NEOs, and the Veres et al. distribution of Earth impacting NEO. The results of the comparison show simplified relative performance metrics, including the expected number of NEOs visible in the search volumes and the initial detection rates expected for each system. Although these simplified comparisons do not capture all of the details, they give considerable insight into the physical factors limiting performance. Multiple asteroid thermal models are considered, including FRM, NEATM, and a new generalized form of FRM (GFRM). I describe issues with how IR albedo and emissivity have been estimated in previous studies, which may render them inaccurate. A thermal model for tumbling asteroids is also developed and suggests that tumbling asteroids may be surprisingly difficult for IR telescopes to observe.

description: Objective This study aims to estimate the association between maternal race and delivery gestational age among women with twin gestations. Study Design Secondary analysis of a prospective, randomized control trial of 17-α hydroxyprogesterone caproate versus placebo for preterm birth (PTB) prevention in twin gestations. Non-Hispanic (NH) black and whites were included. Demographic and antenatal characteristics were compared. The primary outcome was delivery gestational age. Secondary outcomes included a composite of major neonatal morbidity. Kaplan-Meier curves estimated survival probabilities for delivery gestational age by race. Cox proportional hazards models estimated hazard ratios (HR) and 95% confidence intervals (CI). Results A total of 535 women with twin gestations were included; 150 were NH black. NH blacks delivered earlier than NH whites (33.6 ± 4.8 weeks vs. 35.1 ± 3.5 weeks, p < 0.001). Differences in delivery gestational age between NH blacks and whites were consistent across gestation. In adjusted analyses, NH black race (HR: 1.24, 95% CI: 1.02-1.51), prior PTB (HR: 1.59, 95% CI: 1.15-2.19), and cerclage (HR: 3.90, 95% CI: 2.00-7.60) were associated with an increased risk of earlier delivery. Major neonatal morbidity was higher for NH blacks compared with NH whites (12.7 vs. 7.0%, p = 0.036). Conclusion NH blacks with twin gestations have an increased risk of early delivery and neonatal morbidity compared with NH whites.

description: Objective The objective of this study was to apply evolutionary triangulation, a novel technique exploiting evolutionary differentiation among three populations with variable disease prevalence, to spontaneous preterm birth (PTB) genetic association studies. Study Design Single nucleotide polymorphism (SNP) allele frequency data were obtained from HapMap for CEU, GIH/MEX, and YRI/ASW populations. Evolutionary triangulation SNPs, then genes, were selected according to the overlaps of genetic population differences (CEU = outlier). Evolutionary triangulation genes were then compared with three PTB gene lists: (1) top maternal and fetal genes from a large genome-wide association study of PTB, (2) 640 genes from the database for PTB, and (3) 118 genes from a recent systematic review. Empirical p -values were calculated to determine whether evolutionary triangulation enriched for putative PTB associating genes compared with randomly selected sample genes. Results Evolutionary triangulation identified 5/17 maternal genes and 8/16 fetal genes from PTB gene list 1. From list 2, 79/640 were identified by CEU-GIH-YRI evolutionary triangulation, and 57/640 were identified by CEU-ASW-MEX evolutionary triangulation. Finally, 20/118 genes were identified by evolutionary triangulation from gene list 3. For all analyses, p < 0.001 except CEU-ASW-MEX analysis of list 3 where p = 0.002. Conclusion Genes identified in prior PTB association studies confirmed by evolutionary triangulation should be prioritized for further genetic prematurity research.

Beyond first-order asymptotics for Cox regression

Publisher: name: arXiv
Year: 2015
Subjects: subject: Statistics Theory (math.ST)
subject: FOS: Mathematics

description: To go beyond standard first-order asymptotics for Cox regression, we develop parametric bootstrap and second-order methods. In general, computation of $P$-values beyond first order requires more model specification than is required for the likelihood function. It is problematic to specify a censoring mechanism to be taken very seriously in detail, and it appears that conditioning on censoring is not a viable alternative to that. We circumvent this matter by employing a reference censoring model, matching the extent and timing of observed censoring. Our primary proposal is a parametric bootstrap method utilizing this reference censoring model to simulate inferential repetitions of the experiment. It is shown that the most important part of improvement on first-order methods - that pertaining to fitting nuisance parameters - is insensitive to the assumed censoring model. This is supported by numerical comparisons of our proposal to parametric bootstrap methods based on usual random censoring models, which are far more unattractive to implement. As an alternative to our primary proposal, we provide a second-order method requiring less computing effort while providing more insight into the nature of improvement on first-order methods. However, the parametric bootstrap method is more transparent, and hence is our primary proposal. Indications are that first-order partial likelihood methods are usually adequate in practice, so we are not advocating routine use of the proposed methods. It is however useful to see how best to check on first-order approximations, or improve on them, when this is expressly desired.

description: In this study I have explored the capacities of Adult Learning in Iran and Scotland to empower women. I have compared and contrasted the similarities and differences between the formations of Adult Learning in Iran and Scotland. This study is a qualitative study and consists of extraction of semi-structured interviews. Interviewees have been Adult Educators and facilitators in Iran and Scotland. I have shown in this thesis that Adult Education has been changed in its political essence and turned into a tool for psycho-social skills development. However, different configurations of Adult Learning visa-vis feminist contributions may be distinguished in the these spaces. In this thesis Adult Education is being considered in its broader contexts as Adult Learning. Through this study it has been shown that Adult Learning spaces has been the site of transformatory movements for women, especially Muslim women. However, the modes and qualities of change is different in the context of Iran as a Muslim majority country with Scotland as a host for Muslim minority migrants. It is indisputabale that in some instances Adult Learning may be a tool for moving from the present conditions. Nevertheless, this movement may be translated differently in diverse contexts. Sometimes change may be brought about through reproduction of present situation though. It is mandatory to be cautious of the dynamics of the Adult Learning and its potentials which may be merged with knowledge building projects such as Islamic Feminism as far as women’s empowerment is concerned. There are possibilities for women empowerment through implementation of theories such as Islamic Feminism into Adult Learning and vise versa.

description: Objective To estimate the association between severity of thrombocytopenia and postpartum hemorrhage. Study Design We performed a secondary analysis of a prospective cohort of women delivering by cesarean or vaginal birth after cesarean conducted by the National Institute of Child Health and Human Development (NICHD) Maternal-Fetal Medicine Unit. Women delivering ≥ 20 weeks with platelets < 400,000/mL were included. Thrombocytopenia was defined as predelivery platelets of < 150,000/mL. Primary outcomes were (1) laboratory evidence of hemorrhage, defined as a decrease in hemoglobin ≥ 4 mg/dL and (2) clinical evidence of hemorrhage, a composite of atony, transfusion, coagulopathy, hysterectomy, laparotomy, or intensive care unit admission. Odds ratios were calculated for primary outcomes using thrombocytopenia as a dichotomous and ordinal variable. Results A total of 54,597 women were included; 5,611 (10.3%) had antepartum thrombocytopenia, 1,976 (3.6%) women had laboratory evidence of hemorrhage, and 3,862 (7.1%) had clinical evidence of hemorrhage. Thrombocytopenia was associated with both laboratory evidence of hemorrhage (adjusted odds ratio [aOR]: 1.60, 95% CI: 1.38-1.86) and clinical evidence of hemorrhage (aOR: 1.68, 95% CI: 1.52-1.83). The odds of laboratory and clinical evidence of hemorrhage increased incrementally with severity of thrombocytopenia. Conclusion Thrombocytopenia is associated with both laboratory and clinical evidence of hemorrhage; risk increases dramatically as platelet count decreases.

description: Oxygen-defect control has long been considered an influential tuning knob for producing various property responses in complex oxide films. In addition to physical property changes, modification to the lattice structure, specifically lattice expansion, with increasing oxygen vacancy concentrations has been reported often and has become the convention for oxide materials. However, the current understanding of the lattice behavior in oxygen-deficient films becomes disputable when considering compounds containing different bonding environments or atomic layering. Moreover, tensile strain has recently been discovered to stabilize oxygen vacancies in epitaxial films, which further complicates the interpretation of lattice behavior resulting from their appearance. Here, we report on the selective strain control of oxygen vacancy formation and resulting lattice responses in the layered, Ruddlesden-Popper phases, La1.85Sr0.15CuO4. We found that a drastically reduced Gibbs free energy for oxygen vacancy formation near the typical growth temperature for tensile-strained epitaxial LSCO accounts for the large oxygen non-stoichiometry. Additionally, oxygen vacancies form preferentially in the equatorial position of the CuO2 plane, leading to a lattice contraction, rather than the expected expansion, observed with apical oxygen vacancies. Since oxygen stoichiometry plays a key role in determining the physical properties of many complex oxides, the strong strain coupling of oxygen nonstoichiometry and the unusual structural response reported here can provide new perspectives and understanding to the structure and property relationships of many other functional oxide materials.

description: Objective The objective of this study was to identify risk factors associated with the development of septic pelvic thrombophlebitis (SPT). Study Design This is a secondary case-control study of the Eunice Kennedy Shriver National Institute of Child Health and Human Development Maternal-Fetal Medicine Unit Network Cesarean Registry. SPT was defined as suspected infectious thrombosis of the pelvic veins, often persistent febrile illness in the setting of antibiotic therapy for endometritis. Women with SPT were compared with those without SPT using descriptive statistics. Logistic regression models estimated the association between selected risk factors and SPT. Results Of 73,087 women in the cohort, 89 (0.1%) developed SPT. Women with SPT were more likely to be < 20 years old (33.7 vs. 10.6%, p < 0.001), black race (58.4 vs. 29.1%, p < 0.001), and nulliparous (51.1 vs. 23.3%, p < 0.001). Hypertensive disorders of pregnancy (32.6 vs. 11.8%, p < 0.001) and multiple gestation (12.5 vs. 7.4%, p = 0.03) were also more common in women with SPT. In the multivariable regression model, maternal age < 20, black race, multiple gestation, and preeclampsia were all significantly associated with increased odds of SPT (adjusted odds ratio [aOR]: 1.96, 95% confidence interval [CI]: 1.22, 3.14; aOR: 2.6, 95% CI: 1.68, 4.02; aOR: 2.10, 95% CI: 1.13, 3.88; aOR: 2.91, 95% CI: 1.86, 4.57). Conclusion SPT is a rare pregnancy complication. Our analysis confirmed known risk factors (e.g., infections, cesarean delivery), and identified novel ones, including black race, young age, preeclampsia, and multiple gestation.

An Empirical Study of Leading Measures of Dependence

description: In exploratory data analysis, we are often interested in identifying promising pairwise associations for further analysis while filtering out weaker, less interesting ones. This can be accomplished by computing a measure of dependence on all variable pairs and examining the highest-scoring pairs, provided the measure of dependence used assigns similar scores to equally noisy relationships of different types. This property, called equitability, is formalized in Reshef et al. [2015b]. In addition to equitability, measures of dependence can also be assessed by the power of their corresponding independence tests as well as their runtime. Here we present extensive empirical evaluation of the equitability, power against independence, and runtime of several leading measures of dependence. These include two statistics introduced in Reshef et al. [2015a]: MICe, which has equitability as its primary goal, and TICe, which has power against independence as its goal. Regarding equitability, our analysis finds that MICe is the most equitable method on functional relationships in most of the settings we considered, although mutual information estimation proves the most equitable at large sample sizes in some specific settings. Regarding power against independence, we find that TICe, along with Heller and Gorfine's S^DDP, is the state of the art on the relationships we tested. Our analyses also show a trade-off between power against independence and equitability consistent with the theory in Reshef et al. [2015b]. In terms of runtime, MICe and TICe are significantly faster than many other measures of dependence tested, and computing either one makes computing the other trivial. This suggests that a fast and useful strategy for achieving a combination of power against independence and equitability may be to filter relationships by TICe and then to examine the MICe of only the significant ones.

Transparency Material for Data Is the New Protein: How Commonwealth of Virginia Built Digital Resilience Muscle and Responded to Opioid and COVID Shocks

description: During shocks residents and businesses rely upon the government to ensure health, safety, and the continuity of services. The government’s ability to respond depends upon how well it utilizes its data resources and build digital resilience. Yet, governments often fail to integrate data from agencies to effectively respond to shocks. We conceptualize digital resilience as a dynamic capability (DC). Although DC framework provides a theoretical basis, it is unclear what actions managers take to build DC. Through process tracing, we examine how Commonwealth of Virginia (COVA) built DCs and rebounded from two shocks – opioid crisis and COVID-19 pandemic. COVA managers leveraged statewide data assets, built routines to disseminate data, and then reconfigured operational capabilities to build three DCs – relationship building, intelligence creation, and value extraction. Data were the protein that built the digital resilience muscle. We find that the relationship building DC leveraged operational capabilities of data management, integration, and governance structure to foster data sharing. Intelligence creation DC built upon analytics, and the value extraction DC converted analytics into cost savings, revenue-generation, and new services. We find that COVA built robust digital resilience by facilitating data sharing, while the agencies exploited data assets to develop scalable solutions.
