description: To investigate the evolution of metal-enriched gas over recent cosmic epochs as well as to characterize the diffuse, ionized, metal-enriched circumgalactic medium (CGM), we have conducted a blind survey for C IV absorption systems in 89 QSO sightlines observed with the Hubble Space Telescope (HST) Cosmic Origins Spectrograph (COS). We have identified 42 absorbers at z < 0.16, comprising the largest uniform blind sample size to date in this redshift range. Our measurements indicate an increasing C IV absorber number density per comoving path length (dN/dX = 7.5 +/- 1.1) and modestly increasing mass density relative to the critical density of the Universe (Omega(C IV) = 10.0 +/- 1.5 x 10^-8 ) from z ~ 1.5 to the present epoch, consistent with predictions from cosmological hydrodynamical simulations. Furthermore, the data support a functional form for the column density distribution function that deviates from a single power-law, also consistent with independent theoretical predictions. As the data also probe heavy element ions in addition to C IV at the same redshifts, we identify, measure, and search for correlations between column densities of these species where components appear aligned in velocity. Among these ion-ion correlations, we find evidence for tight correlations between C II and Si II, C II and Si III, and C IV and Si IV, suggesting that these pairs of species arise in similar ionization conditions. However, the evidence for correlations decreases as the difference in ionization potential increases. Finally, when controlling for observational bias, we find only marginal evidence for a correlation (86.8% likelihood) between the Doppler line width b(C IV) and column density N(C IV).

Kelvin Helmholtz instability in an ultrathin air film causes drop splashing on smooth surfaces

description: When a fast-moving drop impacts onto a smooth substrate, splashing will be produced at the edge of the expanding liquid sheet. This ubiquitous phenomenon lacks a fundamental understanding. Combining experiment with model, we illustrate that the ultrathin air film trapped under the expanding liquid front triggers splashing. Because this film is thinner than the mean free path of air molecules, the interior airflow transfers momentum with an unusually high velocity comparable to the speed of sound and generates a stress 10 times stronger than the airflow in common situations. Such a large stress initiates Kelvin Helmholtz instabilities at small length scales and effectively produces splashing. Our model agrees quantitatively with experimental verifications and brings a fundamental understanding to the ubiquitous phenomenon of drop splashing on smooth surfaces.

description: Despite the fact that a rigid $Λ$-term is a fundamental building block of the concordance $Λ$CDM model, we show that a large class of cosmological scenarios with dynamical vacuum energy density $ρ_Λ$ and/or gravitational coupling $G$, together with a possible non-conservation of matter, are capable of seriously challenging the traditional phenomenological success of the $Λ$CDM. In this paper, we discuss these "running vacuum models" (RVM's), in which $ρ_Λ=ρ_Λ(H)$ consists of a nonvanishing constant term and a series of powers of the Hubble rate. Such generic structure is potentially linked to the quantum field theoretical description of the expanding Universe. By performing an overall fit to the cosmological observables $SNIa+BAO+H(z)+LSS+BBN+CMB$ (in which the WMAP9, Planck 2013 and Planck 2015 data are taken into account), we find that the class of RVM's appears significantly more favored than the $Λ$CDM, namely at an unprecedented level of $\gtrsim4.2σ$. Furthermore, the Akaike and Bayesian information criteria confirm that the dynamical RVM's are strongly preferred as compared to the conventional rigid $Λ$-picture of the cosmic evolution.

description: Dynamic buckling of an elastic column under compression at constant speed is investigated assuming the first-mode buckling. Two cases are considered: (i) an imperfect column (Hoff's statement), and (ii) a perfect column having an initial lateral deflection. The range of parameters, where the maximum load supported by a column exceeds Euler static force is determined. In this range, the maximum load is represented as a function of the compression rate, slenderness ratio, and imperfection/initial deflection. Considering the results we answer the following question: "How slowly the column should be compressed in order to measure static load-bearing capacity?" This question is important for the proper setup of laboratory experiments and computer simulations of buckling. Additionally, it is shown that the behavior of a perfect column having an initial deflection differ significantlys form the behavior of an imperfect column. In particular, the dependence of the maximum force on the compression rate is non-monotonic. The analytical results are supported by numerical simulations and available experimental data.

description: The widespread use of digital resources, the Internet and the
 development of technology have brought several significant changes in
 reading practices, preferences and use among information consumers.
 Readers of the 21st century have many options for reading thanks to the
 rapid growth of electronic-based reading materials, instead of printed ones,
 such as online newspapers, electronic books, digital encyclopedias, and
 online academic journals, as well as the expansion of e-book readers. All
 of these have contributed to changing readers’ reading strategies, reading
 preferences, and attitudes toward the act of reading. In the field of
 academia, for instance, there has been a tremendous shift from paper-based
 reading to screen-based reading. Given the fact that digital devices have
 become pervasive, and that reading has recently become a digital activity,
 this article proposes the need to investigate the impact of print vs. digital
 reading materials on Moroccan undergraduate students’ reading behaviors,
 preferences and use.

Planet signatures and effect of the chemical evolution of the Galactic thin-disk stars

Publisher: name: arXiv

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: Context: Studies based on high-precision abundance determinations revealed that chemical patterns of solar twins are characterised by the correlation between the differential abundances relative to the Sun and the condensation temperatures (Tc) of the elements. It has been suggested that the origin of this relation is related to the chemical evolution of the Galactic disk, but other processes, associated with the presence of planets around stars, might also be involved. Aims: We analyse HIRES spectra of 14 solar twins and the Sun to provide new insights on the mechanisms that can determine the relation between [X/H] and Tc. Methods: Our spectroscopic analysis produced stellar parameters (Teff, log g, [Fe/H], and $ξ$), ages, masses, and abundances of 22 elements (C, O, Na, Mg, Al, Si, S, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Sr, Y, and Ba). We used these determinations to place new constraints on the chemical evolution of the Galactic disk and to verify whether this process alone can explain the different [X/H]-Tc slopes observed so far. Results: We confirm that the [X/Fe] ratios of all the species correlate with age. The slopes of these relations allow us to describe the effect that the chemical evolution of the Galactic disk has on the chemical patterns of the solar twins. After subtracting the chemical evolution effect, we find that the unevolved [X/H]-Tc slope values do not depend on the stellar ages anymore. However, the wide diversity among these [X/H]-Tc slopes, covering a range of $\pm$4~10$^{-5}$ dex K$^{-1}$, indicates that processes in addition to the chemical evolution may affect the [X/H]-Tc slopes. Conclusions: The wide range of unevolved [X/H]-Tc slope values spanned at all ages by our sample could reflect the wide diversity among exo-planetary systems observed so far and the variety of fates that the matter in circumstellar disks can experience.

description: Even though extensive research into existing CRE alignment models has provided us with valuable insights into the building blocks, components and variables that are needed in the alignment process, these models still fall short in two ways. Most models pay little to no attention to (1) the design of new CRE portfolios and (2) the selection of a new CRE portfolio that adds the most value to the organization. With the development of a new approach, the Preference-based Accommodation Strategy design and decision approach (PAS), I address the deficiencies of the previous alignment models that either place too much emphasis on financial measures or lack clarity in decision making due to the difficulties of quantifying the intangible and subjective. In this chapter the main research question will be answered and recommendations for further research are formulated. How can the Preference-based Accommodation Strategy design and decision approach (PAS) successfully be developed and tested on corporate real estate portfolio level in order to enhance CRE alignment?

THE PROSODY-SYNTAX INTERACTION IN THE "YI-BU-QI-BA" RULE: A MORPHOLOGICALLY CONDITIONED TONE CHANGE IN MANDARIN CHINESE

description: This thesis investigates the prosody-syntax interaction in morpheme specific tone change, presents a systematic comparison between tone Sandhi and tone change, and proposes a new rule-based analysis for the Mandarin "yi-bu-qi-ba" rule. The empirical data is the comparison between Mandarin 3rd Tone Sandhi (3TS) of numeral morpheme wu (`five') and yi (`one') tone change (YTC). Data shows that syntax and prosody do not function the same way in predicting 3TS and YTC. The basic domain of 3TS is a foot whereas the domain of YTC is a phonological word (pword). This thesis also contributes a new analysis for the "yi-bu-qi-ba" rule, with three major claims: (1) YTC only applies when yi is the first element of a pword except in the string of digits. (2) BTC only applies when bu is the first element of a pword. (3) No tone change rule applies to qi and ba any more.

description: A large amount of research has been devoted to the detection and investigation of epistatic interactions in genome-wide association studies (GWASs). Most of the literature focuses on low-order interactions between single-nucleotide polymorphisms (SNPs) with significant main effects.In this paper we propose an original approach for detecting epistasis at the gene level, without systematically filtering on significant genes. We first compute interaction variables for each gene pair by finding its Eigen-Epistasis component, defined as the linear combination of Gene SNPs having the highest correlation with the phenotype. The selection of significant effects is done using a penalized regression method based on Group Lasso controlling the False Discovery Rate.The method is tested against two recent alternative proposals from the literature using synthetic data, and shows good performances in different settings. We demonstrate the power of our approach by detecting new gene-gene interactions on three genome-wide association studies.
Reflecting upon PAS

description: By now, the PAS design decision method is familiar and it is known that: 1 The Preference-Based Design procedure could be adapted and implemented into an accommodation strategy formation project so that it can be used at real estate portfolio level in CRE alignment process (see chapter 4); 2 The stakeholders were able to perform all PAS design decision steps and accepted the outcome (see chapter 5 and 6); 3 The facilitator and the systems engineers were able to represent the pilots in mathematical decision models (see chapter 7), and; 4 The stakeholders evaluated PAS design decision method positively (see chapter 8). In paragraph 9.1 it is shown that the PAS design decision method can be used as add-on to current CRE alignment management models. However, using the PAS method as add-on in these models creates managerial and methodical difficulties. The structure of these models is often not congruent with the structure of the PAS method (see chapter 2). An add-on of the PAS method in an alignment model does not fit well. To avoid these difficulties in the pilot studies a specific CRE alignment management system is set up which is congruent with the PAS design decision system: the PAS design decision management system. The PAS design decision method has been structured from a decision making perspective around Kickert’s three rationalities (components) (in De Leeuw, 2002). To complete PAS, PAS is described solely as design method in paragraph 9.2. In paragraph 9.3 the PAS management system is structured from a systems’ management perspective. From this perspective the three components can be described from the organizations’ point of view as well as the CRE manager and facilitator that executes PAS. Management as such is seen as steering in this thesis as is explained in chapter 3. PAS management system is defined based on a systems perspective as following the chosen basic concepts and definitions as explained in paragraph 3.1.14 and 3.1.15.

Tau Therapeutic Targeting Through Pathological PAD Interactions in ADRD
Creators: name: Nowar, Raghd M
Publisher: name: University of Illinois at Chicago
Year: 2023

description: Alzheimer’s disease (AD) is a devastating neurodegenerative disorder, accounting for 60-80% of dementia, for which there are no effective therapies. The hallmark neuropathologies are protein deposition of amyloid-β (Aβ) and tau neurofibrillary tangles (NFTs). Therapeutic targeting of tau has not been widely explored in clinical trials. Recent findings provide new insight into tau pathology: Exposure of a 17 amino acid N-terminal sequence of tau that is sequestered in normal brain appears to be necessary. This region comprises a Phosphatase Activation Domain (PAD) that is aberrantly displayed in all pathological forms of tau. Interestingly, PAD acts as biologically active motif that is sufficient to activate a signaling pathway involving protein phosphatase 1 (PP1) and glycogen synthase kinase 3β (GSK3β) that is associated with the inhibition of fast axonal transport and toxicity in neurons. The monoclonal antibody (TNT1), specific for the PAD-tau epitope, blocks toxic effects of pathogenic tau. Therefore, PAD provides a molecular basis for altered kinase activities in AD and tauopathies representing a novel therapeutic target to treat tauopathies and AD Related Disorders. Based on these observations, a HTS screen strategy was developed based on AlphaLisa technology with a goal of identifying small molecules that can inhibit the PAD/TNT1 protein-protein interaction (PPI). Eleven hits were identified from initial screens inhibit the PAD-TNT interaction with sub-micromolar IC50s. These compounds serve as a basis for developing candidate therapeutics in collaboration with the Thatcher laboratory at the University of Arizona. We have successfully designed and optimized cell-based assays utilizing NanoBRET technology for validation of target engagement in neurons. Synthetic test compounds developed from the initial screen were found to efficiently disrupt the pathological PAD-Tau-PP1γ interaction at nanomolar concentrations. Compounds were tested for toxicity in both HEK293t and primary cultured cortical neurons, where no toxicity was associated with tested compounds. Three developed compounds were tested for their ability to rescue neurodegeneration and axonal transport disruption using immunostaining and confocal imaging as well as assessing their ability to inhibit Tau-PP1γ interaction. This phenotypic validation is important for establishing therapeutic efficacy and is critical for optimization of vivo dose response for active candidate compounds.

description: We study the evolution of star clusters on circular and eccentric orbits using direct $N$-body simulations. We model clusters with initially $N=8{\rm k}$ and $N=16{\rm k}$ single stars of the same mass, orbiting around a point-mass galaxy. For each orbital eccentricity that we consider, we find the apogalactic radius at which the cluster has the same lifetime as the cluster with the same $N$ on a circular orbit. We show that then, the evolution of bound particle number and half-mass radius is approximately independent of eccentricity. Secondly, when we scale our results to orbits with the same semi-major axis, we find that the lifetimes are, to first order, independent of eccentricity. When the results of Baumgardt and Makino for a singular isothermal halo are scaled in the same way, the lifetime is again independent of eccentricity to first order, suggesting that this result is independent of the Galactic mass profile. From both sets of simulations we empirically derive the higher order dependence of the lifetime on eccentricity. Our results serve as benchmark for theoretical studies of the escape rate from clusters on eccentric orbits. Finally, our results can be useful for generative models for cold streams and cluster evolution models that are confined to spherical symmetry and/or time-independent tides, such as Fokker-Planck models, Monte Carlo models, and (fast) semi-analytic models.

Subjects: subject: 300

description: Die vorliegende Masterarbeit gibt einen Überblick über menschenfeindliche Einstellungen von Personen, die sich selbst in der politischen Mitte der Gesellschaft verorten. Als Orientierung dient hierbei das Konzept der Gruppenbezogenen Menschenfeindlichkeit. Nach der Darstellung der menschenfeindlichen Einstellungen im Datenmaterial wird in dieser Arbeit einerseits dargestellt, wie diese Einstellungen gerechtfertigt werden als auch wie sich diese äußern. Dafür wird die Heuristik der Rechtfertigungsnarrative hinzugezogen. Für die Analyse dieser Arbeit wird empirisches Datenmaterial verwendet, welches während einer Projektarbeit am Institut für interdisziplinäre Konflikt- und Gewaltforschung erhoben wurde. Mittels der qualitativen Inhaltsanalyse nach Mayring (2015) wird das empirische Datenmaterial tiefergehend analysiert und in einem weiteren Schritt mit Ergebnissen aus geführten Expert:innen-Interviews ergänzt.

 Wie bereits andere Studien gezeigt haben, macht auch diese Arbeit menschenfeindliche Einstellungen in der Gesellschaft sichtbar. Dies geschieht jedoch mit dem Unterschied, dass es sich hierbei um qualitative Daten handelt. Eine weitere Erkenntnis der vorliegenden Arbeit ist, dass eine deutlich zu erkennende Diskrepanz zwischen geäußerten Meinungen und der politischen Selbstverortung derselben Personen herrscht. Darüber hinaus wird aufgezeigt, wie die befragten Personen, die diese Diskrepanz aufweisen, diese Einstellungen rechtfertigen. Dabei ist zu erkennen, dass sich viele menschenfeindlichen Einstellungen in ihren Äußerungen ähneln und in gegenseitiger Wechselwirkung zueinanderstehen. Außerdem macht diese Arbeit sichtbar, dass sogenannte Rechtfertigungsnarrative häufig vor oder direkt hinter menschenfeindlichen Äußerungen verwendet werden.
A Study of Prudentius' Use of Vergil and Lucan In the Fifth Combat of the Psychomachia

description: This thesis examines what I consider to be meaningful allusions to Vergil's Aeneid and Lucan's Bellum Civile in Prudentius' Psychomachia. Crucial to my interpretation that a particular passage constitutes an intentional borrowing is that the consideration of the source text - and of the context of the verbal parallel within the source text - enhances our understanding of Prudentius' poem. My study, then, locates what I consider to be intentional allusions, analyzes them in their context within the source texts, and discusses their meaning within the Psychomachia. My focus is on the speech of Sobrietas (Psychomachia 351-406). This speech is replete with allusions to Vergil's Aeneid and to Lucan's Bellum Civile, including direct quotes, clusters of words and phrases, and verbal images. I hope to show that these allusions are deliberate and, in the case of Sobrietas' speech, often demonstrate some intentional undermining of their original context.

description: Nonequilibrium Greens function techniques (NEGF) combined with density functional theory (DFT) calculations have become a standard tool for the description of electron transport through single molecule nanojunctions in the coherent tunneling regime. However, the applicability of these methods for transport in the Coulomb blockade regime is questionable. For a molecular assembly model, with multideterminant calculations as a benchmark, we show how a closed shell ansatz, the usual ingredient of meanfield methods, fails to properly describe the step like electron transfer characteristic in weakly coupled systems. Detailed analysis of this misbehavior allows us to propose a practical scheme to extract the addition energies in the CB regime for single-molecule junctions from NEGF DFT within the local density approximation (closed shell). We show also that electrostatic screening effects are taken into account within this simple approach.
PAS evaluation

Year: 2019

description: In this chapter the evaluation of PAS will be discussed. The use of PAS has been extensively reported in chapters 5 (steps), 6 (stakeholder & activities) and 7 (mathematical model). The use of PAS has been successful, this means that stakeholders are able to use PAS. In this chapter the evaluation of the stakeholders of PAS is discussed. This answers the question if the stakeholders want to use PAS. Recall, that PAS comprises of steps, stakeholders & activities, and mathematical models. The activities consist of a sequence of interviews and workshops and a simultaneous design and calibration of the mathematical model. The pilots resulted in a final design alternative and a final mathematical model. The evaluation is given per pilot study and this chapter has the following structure: –– TU Delft pilot for the food facilities in paragraph 8.1; –– TU Delft pilot for lecture halls in paragraph 8.2; –– Oracle’s pilot for office locations in paragraph 8.3; –– Pilot comparison and conclusion in paragraph 8.4. In each of these paragraphs, the four types of measurements that Joldersma and Roelofs (2004) use, will be addressed. In the first subparagraph the stakeholders’ evaluation is discussed. Here, the first three measurements were addressed: (1) experiences with PAS, (2) attractiveness of PAS and (3) participants’ observations on effectiveness of PAS. In general, it is not indicated which particular stakeholder gave feedback if their role in the organization was not relevant for the remark. Only in cases where the role and background of the stakeholder was relevant to their remarks, it is indicated which particular stakeholder gave these remarks. In the second subparagraph, the fourth measurement, namely the observers’ perceptions of the effectiveness of PAS is reported. In the text, the frequently mentioned positive aspects and areas of improvement are underlined and will be used in the conclusion and pilot comparison.

description: Increasing the statistics of spectroscopically confirmed evolved massive stars in the Local Group enables the investigation of the mass loss phenomena that occur in these stars in the late stages of their evolution. We aim to complete the census of luminous mid-IR sources in star-forming dwarf irregular (dIrr) galaxies of the Local Group. To achieve this we employed mid-IR photometric selection criteria to identify evolved massive stars, such as red supergiants (RSGs) and luminous blue variables (LBVs), by using the fact that these types of stars have infrared excess due to dust. The method is based on 3.6 $μ$m and 4.5 $μ$m photometry from archival ${\it Spitzer}$ Space Telescope images of nearby galaxies. We applied our criteria to 4 dIrr galaxies: Pegasus, Phoenix, Sextans A, and WLM, selecting 79 point sources, which we observed with the VLT/FORS2 spectrograph in multi-object spectroscopy mode. We identified 13 RSGs, of which 6 are new discoveries, also 2 new emission line stars, and 1 candidate yellow supergiant. Among the other observed objects we identified carbon stars, foreground giants, and background objects, such as a quasar and an early-type galaxy that contaminate our survey. We use the results of our spectroscopic survey to revise the mid-IR and optical selection criteria for identifying RSGs from photometric measurements. The optical selection criteria are more efficient in separating extragalactic RSGs from foreground giants than mid-IR selection criteria, however the mid-IR selection criteria are useful for identifying dusty stars in the Local Group. This work serves as a basis for further investigation of the newly discovered dusty massive stars and their host galaxies.

Macroscopic Einstein Equations for a Cosmological Model with $λ$-term
Creators: name: Ignat'ev, Yurii
Publisher: name: arXiv

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: Through averaging the Einstein equations over transverse gravitational perturbations it is obtained a closed system of two ordinary differential equations describing macroscopic cosmological evolution of the isotropic space-flat Universe filled with gravitational radiation. It is found an asymptotic solution of evolution equation for gravitational perturbation amplitude. Making the substitution of this solution into Einstein equation averaged over gravitational perturbations, the single evolution non-linear ordinary differential second-order equation relative to macroscopic scale factor is obtained. It is also found a solution of evolution equation for scale factor in WKB-approximation which analytically describes the process of transformation from ultrarelativistic regime of cosmological extension to inflationary one.

A counterexample to a result on the tree graph of a graph

description: Given a set of cycles C of a graph G, the tree graph of G defined by C is the graph T(G,C) whose vertices are the spanning trees of G and in which two trees R and S are adjacent if the union of R and S contains exactly one cycle and this cycle lies in C. Li et al [Discrete Math 271 (2003), 303--310] proved that if the graph T(G,C) is connected, then C cyclically spans the cycle space of G. Later, Yumei Hu [Proceedings of the 6th International Conference on Wireless Communications Networking and Mobile Computing (2010), 1--3] proved that if C is an arboreal family of cycles of G which cyclically spans the cycle space of a $2$-connected graph G, then T(G, C) is connected. In this note we present an infinite family of counterexamples to Hu's result.
InFluence: An open-source python package to model images captured with direct electron detectors

description: The high detection efficiencies of direct electron detectors facilitate the routine collection of low fluence electron micrographs and diffraction patterns. Low dose and low fluence electron microscopy experiments are the only practical way to acquire useful data from beam sensitive pharmaceutical and biological materials. Appropriate modeling of low fluence images acquired using direct electron detectors is, therefore, paramount for quantitative analysis of the experimental images. We have developed a new open-source Python package to accurately model any single layer direct electron detector for low and high fluence imaging conditions, including a means to validate against experimental data through computation of modulation transfer function and detective quantum efficiency
SAR Prediction and SAR Management for Parallel Transmit MRI
Creators: name: Homann, Hanno
Publisher: name: KIT Scientific Publishing

Subjects: Magnetic Resonance Imaging (MRI)
Specific Absorption Rate (SAR)
patient safety
radio frequency
parallel transmission

description: Parallel transmission enables control of the RF field in high-field Magnetic Resonance Imaging (MRI). However, the approach has also caused concerns about the specific absorption rate (SAR) in the patient body. The present work provides new concepts for SAR prediction. A novel approach for generating human body models is proposed, based on a water-fat separated MRI pre-scan. Furthermore, this work explores various approaches for SAR reduction.
Co-spatial Long-slit UV/Optical Spectra of Ten Galactic Planetary Nebulae with HST/STIS II. Nebular Models, Central Star Properties and He+CNO Synthesis

description: The goal of the present study is twofold. First, we employ new HST/STIS spectra and photoionization modeling techniques to determine the progenitor masses of eight planetary nebulae (IC 2165, IC 3568, NGC 2440, NGC 3242, NGC 5315, NGC 5882, NGC 7662 and PB6). Second, for the first time we are able to compare each object's observed nebular abundances of helium, carbon and nitrogen with abundance predictions of these same elements by a stellar model that is consistent with each object's progenitor mass. Important results include the following: 1) the mass range of our objects' central stars matches well with the mass distribution of other PN central stars and white dwarfs; 2) He/H is above solar in all of our objects, in most cases likely due to the predicted effects of first dredge up; 3) most of our objects show negligible C enrichment, probably because their low masses preclude 3rd dredge-up; 4) C/O versus O/H for our objects appears to be inversely correlated, perhaps consistent with the conclusion of theorists that the extent of atmospheric carbon enrichment from first dredge-up is sensitive to a parameter whose value increases as metallicity declines; 5) stellar model predictions of nebular C and N enrichment are consistent with observed abundances for progenitor star masses <=1.5 Msun. Finally, we present the first published photoionization models of NGC 5315 and NGC 5882.
