description: This paper presents the design and implementation of the front-end electronics and the data acquisition (DAQ) system for readout of multi-wire drift chambers (MWDC). Apart of the conventional drift time measurement the system delivers the hit position along the wire utilizing the charge division technique. The system consists of preamplifiers, and analog and digital boards sending data to a back-end computer via an Ethernet interface. The data logging software formats the received data and enables an easy access to the data analysis software. The use of specially designed preamplifiers and peak detectors allows the charge-division readout of the low resistance signal wire. The implication of the charge-division circuitry onto the drift time measurement was studied and the overall performance of the electronic system was evaluated in dedicated off-line tests.

description: Molecular snow lines in protoplanetary disks have been studied theoretically for decades because of their importance in shaping planetary architectures and compositions. The water snow line lies in the planet formation region at < 10 AU, and so far its location has been estimated only indirectly from spatially-unresolved spectroscopy. This work presents a proof-of-concept method to directly image the water snow line in protoplanetary disks through its physical and chemical imprint in the local dust properties. We adopt a physical disk model that includes dust coagulation, fragmentation, drift, and a change in fragmentation velocities of a factor 10 between dry silicates and icy grains as found by laboratory work. We find that the presence of a water snow line leads to a sharp discontinuity in the radial profile of the dust emission spectral index α_mm, due to replenishment of small grains through fragmentation. We use the ALMA simulator to demonstrate that this effect can be observed in protoplanetary disks using spatially-resolved ALMA images in two continuum bands. We explore the model dependence on the disk viscosity and find that the spectral index reveals the water snow line for a wide range of conditions, with opposite trends when the emission is optically thin rather than thick. If the disk viscosity is low (α_visc < 10^-3) the snow line produces a ring-like structure with a minimum at α_mm ~ 2 in the optically thick regime, possibly similar to what has been measured with ALMA in the innermost region of the HL Tau disk.

description: Shock waves exist throughout the universe and are fundamental to understanding the nature of collisionless plasmas. Reformation is a process, driven by microphysics, which typically occurs at high Mach number supercritical shocks. While ongoing studies have investigated this process extensively both theoretically and via simulations, their observations remain few and far between. In this letter we present a study of very high Mach number shocks in a parameter space that has been poorly explored and we identify reformation using in situ magnetic field observations from the Cassini spacecraft at 10 AU. This has given us an insight into quasi-perpendicular shocks across two orders of magnitude in Alfven Mach number (MA) which could potentially bridge the gap between modest terrestrial shocks and more exotic astrophysical shocks. For the first time, we show evidence for cyclic reformation controlled by specular ion reflection occurring at the predicted timescale of ~0.3 τc, where τc is the ion gyroperiod. In addition, we experimentally reveal the relationship between reformation and MA and focus on the magnetic structure of such shocks to further show that for the same MA, a reforming shock exhibits stronger magnetic field amplification than a shock that is not reforming.

description: The presence and abundance of the short-lived radioisotopes (SLRs) $^{26}$Al and $^{60}$Fe during the formation of the Solar System is difficult to explain unless the Sun formed in the vicinity of one or more massive star(s) that exploded as supernovae. Two different scenarios have been proposed to explain the delivery of SLRs to the protosolar nebula: (i) direct pollution of the protosolar disc by supernova ejecta and (ii) the formation of the Sun in a sequential star formation event in which supernovae shockwaves trigger further star formation which is enriched in SLRs. The sequentially triggered model has been suggested as being more astrophysically likely than the direct pollution scenario. In this paper we investigate this claim by analysing a combination of $N$-body and SPH simulations of star formation. We find that sequential star formation would result in large age spreads (or even bi-modal age distributions for spatially coincident events) due to the dynamical relaxation of the first star-formation event(s). Secondly, we discuss the probability of triggering spatially and temporally discrete populations of stars and find this to be only possible in very contrived situations. Taken together, these results suggest that the formation of the Solar System in a triggered star formation event is as improbable, if not more so, than the direct pollution of the protosolar disc by a supernova.

Year: 2025

description: BACKGROUND: Live birth weighing less than 2500 grams, and a preterm delivery are major causes of morbidity and mortality among infants in the United States. African American women were characterized with increased rate of low birth weight and preterm birth. Previous works on prenatal counseling as a preventive measure in reducing preterm and low birth weight is understudy, further research is required. This study examines correlations between early prenatal counseling and incidence of preterm and low birth weight among African American women.METHOD: A descriptive analysis using chi-square test was conducted on women in the 2018 Natality Public Use data. Using random sampling, ratio 5:1, 7,600 White women and 1400 African American women were randomly selected to be included in the study. Data was analyzed using SPSS version 24. A p value of ≤ 0.05 was considered a significant finding of the study.RESULTS: African American women who started prenatal care early are more likely to deliver full term baby (p=0.003), African American women with increased number of prenatal visits are less likely to have preterm birth (p=0.001), no significant relationship (p=0.071) between initiation of prenatal care and the birth weight but there were statistical significant relationships (p=0.001) between number of prenatal visits and the birth weight; increase number of prenatal visits correlate positively with birth weight. There is positive correlation between Government Nutrition Program-WIC and the birth weight (p=0.002); women who received WIC benefits during pregnancy are more likely to have higher birth weight. The relationship between mother’s age significantly correlate to birth weight; average birth weight of babies born by African American women increased with increasing age till 25-39 and decline at age 40 and above (p=0.041). Finally, gestational hypertension was found to be statistically significant with obstetric estimates and birth weight (p=0.001). African American women with gestational hypertension were more likely to have very low birth weight.CONCLUSION: The findings suggest that there is a significant reduced risk of preterm birth and low birth weight among African American women when they start prenatal care early and be receptive to prenatal counseling as early as possible during pregnancy.

description: Der Beitrag skizziert die bedeutsame Rolle der liberalen badischen Mädchenschulpolitik im Rahmen der ersten Koedukationsdebatte um die Jahrhundertwende zum 20. Jahrhundert. Die Erfahrungen mit der ‚Koinstruktion‘ von Mädchen in badischen Knabenschulen widerlegten zahlreiche Argumente der KoedukationsgegnerInnen, die sich vorwiegend auf eine ‚naturgewollte‘ physische und psychische Andersartigkeit – in der Regel einer Inferiorität – von Frauen stützten und daraus eine spezifische weibliche Bestimmung ableiteten. Je größer die angenommene und sozial erwünschte Konstruktion einer scharfen Geschlechterdifferenz betont wurde, umso vehementer wurde auch der gemeinsame Schulbesuch von Mädchen und Jungen abgelehnt. Postulierte Geschlechterdifferenzen und Geschlechterrollen spielen in der aktuellen Diskussion um Geschlechtertrennung nach wie vor eine Rolle. Zwar liefern Geschlechterdifferenzen heute keine tragfähige argumentative Grundlage mehr für die Konstruktion von Geschlechterrollen, aber sie werden noch immer argumentativ herangezogen, um Vorteile der institutionellen Trennung zu unterstreichen.

description: We present a new method to identify luminous off-nuclear X-ray sources in the outskirts of galaxies from large public redshift surveys, distinguishing them from foreground and background interlopers. Using the 3XMM-DR5 catalog of X-ray sources and the SDSS DR12 spectroscopic sample of galaxies, with the help of this off-nuclear cross-matching technique, we selected 98 sources with inferred X-ray luminosities in the range $10^{41} < L_{\rm X} < 10^{44}\,{\rm erg\,s}^{-1}$, compatible with hyperluminous X-ray objects (HLX). To validate the method, we verify that it allowed us to recover known HLX candidates such as ESO 243$-$49 HLX$-$1 and M82 X$-$1. From a statistical study, we conservatively estimate that up to $71 \pm 11$ of these sources may be fore- or background sources, statistically leaving at least 16 that are likely to be HLXs, thus providing support for the existence of the HLX population. We identify two good HLX candidates and using other publicly available datasets, in particular the VLA FIRST in radio, UKIDSS in the near-infrared, GALEX in the ultra-violet and CFHT Megacam archive in the optical, we present evidence that these objects are unlikely to be foreground or background X-ray objects of conventional types, e.g. active galactic nuclei, BL Lac objects, Galactic X-ray binaries or nearby stars. However, additional dedicated X-ray and optical observations are needed to confirm their association with the assumed host galaxies and thus secure their HLX classification.

From Tholos to palace: individual and corporate identity in prepalatial burials and seal iconography
Creators: name: Galligan, Erin Elaine
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: Seals from prepalatial Minoan Crete have been dismissed as purely decorative objects. It is not until the first palaces are founded around 1900 BCE that archaeological evidence reveals that seals are used in regional administration systems. This paper argues that seals are items with economic significance, whose designs are meant to communicate messages in island-wide exchange networks. These designs have the potential to express both the individual identity of the seal owner and the relationship of the seal owner to a group with economic authority. By looking at changes in iconography from the Early Minoan II through the Middle Minoan II periods, one can identify an increase in social hierarchy in the period immediately preceding the foundation of the first palaces. The results from the study of seal iconography can be compared to burial data to reveal changing strategies in legitimation of economic and ritual authority as social complexity grows.

The Integrated Calcium II Triplet as a Metallicity Indicator: Comparisons with High Resolution [Fe/H] in M31 Globular Clusters

description: Medium resolution (R=4,000 to 9,000) spectra of the near infrared Ca II lines (at 8498, 8542, and 8662 A) in M31 globular cluster integrated light spectra are presented. In individual stars the Ca II triplet (CaT) traces stellar metallicity; this paper compares integrated CaT strengths to well determined, high precision [Fe/H] values from high resolution integrated light spectra. The target globular clusters cover a wide range in metallicity (from [Fe/H] = -2.1 to -0.2). While most are older than 10 Gyr, some may be of intermediate age (2-6 Gyr). A handful (3-6) have detailed abundances (e.g. low [Ca/Fe]) that indicate they may have been accreted from dwarf galaxies. Using various measurements and definitions of CaT strength, it is confirmed that for GCs with [Fe/H] < -0.4 and older than 2 Gyr the integrated CaT traces cluster [Fe/H] to within about 0.2 dex, independent of age. CaT lines in metal rich GCs are very sensitive to nearby atomic lines (and TiO molecular lines in the most metal rich GCs), largely due to line blanketing in continuum regions. The [Ca/Fe] ratio has a mild effect on the integrated CaT strength in metal poor GCs. The integrated CaT can therefore be safely used to determine rough metallicities for distant, unresolved clusters, provided that attention is paid to the limits of the measurement techniques.

description: This paper is the first paper of three papers in a series, which intend to provide a systematic treatment for the space-filling curves of self-similar sets. In the present paper, we introduce a notion of \emph{linear graph-directed IFS} (linear GIFS in short). We show that to construct a space-filling curve of a self-similar set, it is amount to explore its linear GIFS structures. Some other notions, such as chain condition, path-on-lattice IFS, and visualizations of space-filling curves are also concerned. In sequential papers \cite{Dai15} and \cite{RZ14}, we obtain a universal algorithm to construct space-filling curves of self-similar sets of finite type, that is, as soon as the IFS is given, the computer will do everything automatically. Our study extends almost all the known results on space-filling curves.

Family and nation: Cherokee orphan care, 1835-1903
Creators: name: Reed, Julie
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: In 1872, the Cherokee Nation established its Orphan Asylum as a means to provide support and education to its orphaned children. The Asylum, like hundreds across the United States, provided a modern means to care for orphan children, but unlike other institutions in Indian Territory or the United States, the Cherokees controlled all facets of the institution. The Asylum combined English education, manual labor, and a home to hundreds of Cherokee children. As the Cherokee Nation faced threats from white settlement, federal proposals to make Indian Territory a United States Territory, railroad companies, and allotment, the Orphan Asylum emerged as a symbol of the Cherokees' sovereign status and aided the transmission of traditional values rooted in community and family to its next generation.

description: We present the first scattered-light image of the debris disk around HD 131835 in $H$ band using the Gemini Planet Imager. HD 131835 is a $\sim$15 Myr old A2IV star at a distance of $\sim$120 pc in the Sco-Cen OB association. We detect the disk only in polarized light and place an upper limit on the peak total intensity. No point sources resembling exoplanets were identified. Compared to its mid-infrared thermal emission, the disk in scattered light shows similar orientation but different morphology. The scattered-light disk extends from $\sim$75 to $\sim$210 AU in the disk plane with roughly flat surface density. Our Monte Carlo radiative transfer model can well describe the observations with a model disk composed of a mixture of silicates and amorphous carbon. In addition to the obvious brightness asymmetry due to stronger forward scattering, we discover a weak brightness asymmetry along the major axis with the northeast side being 1.3 times brighter than the southwest side at a 3-σ level.

Magneto-thermal Disk Wind from Protoplanetary Disks

description: Global evolution and dispersal of protoplanetary disks (PPDs) is governed by disk angular momentum transport and mass-loss processes. Recent numerical studies suggest that angular momentum transport in the inner region of PPDs is largely driven by magnetized disk wind, yet the wind mass-loss rate remains unconstrained. On the other hand, disk mass loss has conventionally been attributed to photoevaporation, where external heating on the disk surface drives a thermal wind. We unify the two scenarios by developing a 1D model of magnetized disk winds with a simple treatment of thermodynamics as a proxy for external heating. The wind properties largely depend on 1) the magnetic field strength at the wind base, characterized by the poloidal Alfvén speed $v_{Ap}$, 2) the sound speed $c_s$ near the wind base, and 3) how rapidly poloidal field lines diverge (achieve $R^{-2}$ scaling). When $v_{Ap}\gg c_s$, corotation is enforced near the wind base, resulting in centrifugal acceleration. Otherwise, the wind is accelerated mainly by the pressure of the toroidal magnetic field. In both cases, the dominant role played by magnetic forces likely yields wind outflow rates that well exceed purely hydrodynamical mechanisms. For typical PPD accretion-rate and wind-launching conditions, we expect $v_{Ap}$ to be comparable to $c_s$ at the wind base. The resulting wind is heavily loaded, with total wind mass loss rate likely reaching a considerable fraction of wind-driven accretion rate. Implications for modeling global disk evolution and planet formation are also discussed.

The scale was designed to capture the phenomenon of peer sexual harassment (victimization, perpetration, and witnessing) among children in late childhood (ages 10–12 years) in the school context. The aim of this study was to explore the possibility to measure peer sexual harassment in late childhood in a meaningful way by testing the scale’s reliability, convergent validity, and response rate; and, to explore the scale’s factor structure of peer sexual harassment as a construct in the targeted age group.

description: Consider the following Online Boolean Matrix-Vector Multiplication problem: We are given an $n\times n$ matrix $M$ and will receive $n$ column-vectors of size $n$, denoted by $v_1,\ldots,v_n$, one by one. After seeing each vector $v_i$, we have to output the product $Mv_i$ before we can see the next vector. A naive algorithm can solve this problem using $O(n^3)$ time in total, and its running time can be slightly improved to $O(n^3/\log^2 n)$ [Williams SODA'07]. We show that a conjecture that there is no truly subcubic ($O(n^{3-ε})$) time algorithm for this problem can be used to exhibit the underlying polynomial time hardness shared by many dynamic problems. For a number of problems, such as subgraph connectivity, Pagh's problem, $d$-failure connectivity, decremental single-source shortest paths, and decremental transitive closure, this conjecture implies tight hardness results. Thus, proving or disproving this conjecture will be very interesting as it will either imply several tight unconditional lower bounds or break through a common barrier that blocks progress with these problems. This conjecture might also be considered as strong evidence against any further improvement for these problems since refuting it will imply a major breakthrough for combinatorial Boolean matrix multiplication and other long-standing problems if the term "combinatorial algorithms" is interpreted as "non-Strassen-like algorithms" [Ballard et al. SPAA'11]. The conjecture also leads to hardness results for problems that were previously based on diverse problems and conjectures, such as 3SUM, combinatorial Boolean matrix multiplication, triangle detection, and multiphase, thus providing a uniform way to prove polynomial hardness results for dynamic algorithms; some of the new proofs are also simpler or even become trivial. The conjecture also leads to stronger and new, non-trivial, hardness results.

description: Darwin's theory of evolution - as introduced in game theory by Maynard Smith - is not the only important evolutionary aspect in a evolutionary dynamics, since complex interdependencies, competition, and growth should be modeled by, for example, reactive aspects. In the ultimatum game the reciprocity and the fifty-fifty partition seems to be a deviation from rational behavior of the players under the light of the Nash equilibrium concept.Such equilibrium emerges, for example, from the punishment of the responder who generally tends to refuse unfair proposals. In the iterated version of the game, the proposers are able to improve their proposals by adding a value thus making fairer proposals. Such evolutionary aspects are not properly Darwinian-motivated, but they are endowed with a fundamental aspect: they reflect their actions according to value of the offers. Recently, a reactive version of the ultimatum game where acceptance occurs with fixed probability was proposed. In this paper, we aim at exploring this reactive version of the ultimatum game where the acceptance by players depends on the offer. In order to do so, we analyze two situations: (i) mean field and (ii) we consider players inserted within the networks with arbitrary coordination. We then show that the reactive aspect, here studied, thus far not analyzed in the evolutionary game theory literature can unveil an essential feature for the convergence to fifty-fifty split. Moreover we also analyze populations under four different polices ranging from a highly conservative to a moderate one, with respect to decision in changing the proposal based on acceptations. We show that the idea of gaining less more times added to the reciprocity of the players is highly relevant to the "healthy" societies population bargaining concept.

Who's driving?: uncovering the source of opinion change in American politics

description: This paper attempts to determine whether citizens that "drive" changes in public opinion share certain demographic characteristics. Extant theory informs us that these citizens should be attentive to media signals (sophisticated) and unattached to either side of the ideological spectrum (moderate). Conversely, unsophisticated ideologues should be unresponsive because they do not pay attention to media signals and are attached to an ideology that mitigates their response. I analyze three time series from the General Social Survey. In each, I find parallel opinion movement from sophisticated moderates and unsophisticated ideologues. Using regression analysis, I find that sophisticated moderates contribute significantly more to changes in executive confidence, unsophisticated ideologues contribute significantly more to changes in welfare spending preferences, and both strata contribute equally to changes in defense spending preferences. I conclude that the extant theory is not supported empirically; there is no evidence that sophisticated moderates consistently "drive" changes in public opinion.

description: The direct genetically encoded cell-based synthesis of non-natural peptide and depsipeptide macrocycles is an outstanding challenge. Here we programme the encoded synthesis of 25 diverse non-natural macrocyclic peptides, each containing two non-canonical amino acids, in Syn61Δ3-derived cells; these cells contain a synthetic Escherichia coli genome in which the annotated occurrences of two sense codons and a stop codon, and the cognate transfer RNAs (tRNAs) and release factor that normally decode these codons, have been removed. We further demonstrate that pyrrolysyl-tRNA synthetase/tRNA pairs from distinct classes can be engineered to direct the co-translational incorporation of diverse alpha hydroxy acids, with both aliphatic and aromatic side chains. We define 49 engineered mutually orthogonal pairs that recognize distinct non-canonical amino acids or alpha hydroxy acids and decode distinct codons. Finally, we combine our advances to programme Syn61Δ3-derived cells for the encoded synthesis of 12 diverse non-natural depsipeptide macrocycles, which contain two non-canonical side chains and either one or two ester bonds.

description: Advances in the amplification and manipulation of ultrashort laser pulses has led to revolutions in several areas. Examples include chirped pulse amplification for generating high peak-power lasers, power-scalable amplification techniques, pulse shaping via modulation of spatially-dispersed laser pulses, and efficient frequency-mixing in quasi-phase-matched nonlinear crystals to access new spectral regions. In this work, we introduce and demonstrate a new platform for nonlinear optics which has the potential to combine all of these separate functionalities (pulse amplification, frequency transfer, and pulse shaping) into a single monolithic device. Moreover, our approach simultaneously offers solutions to the performance-limiting issues in the conventionally-used techniques, and supports scaling in power and bandwidth of the laser source. The approach is based on two-dimensional patterning of quasi-phase-matching gratings combined with optical parametric interactions involving spatially dispersed laser pulses. Our proof of principle experiment demonstrates this new paradigm via mid-infrared optical parametric chirped pulse amplification of few-cycle pulses.

description: The possibility to have singular accelerated evolution in the context of $F(R)$ bimetric gravity is investigated. Particularly, we study two singular models of cosmological evolution, one of which is a singular modified version of the Starobinsky $R^2$ inflation model. As we demonstrate, for both models in some cases, the slow-roll parameters become singular at the Type IV singularity, a fact that we interpret as a dynamical instability of the theory under study. This dynamically instability may be an indicator of graceful exit from inflation and we thoroughly discuss this scenario and the interpretation of the singular slow-roll parameters. Furthermore, it is demonstrated that for some versions of $F(R)$ bigravity, singular inflation is realized in consistent way so that inflationary indices are compatible with Planck data. Moreover, we study the late-time behavior of the two singular models and we show that the unified description of early and late-time acceleration can be achieved in the context of bimetric $F(R)$ gravity.
