The Physics probed by the P_T Dependence of the Nuclear Suppression Factor
Creators: name: Renk, Thorsten
Publisher: name: arXiv
Year: 2013
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The nuclear suppression factor R_AA of single inclusive hadrons measured in ultrarelativistic heavy-ion collisions was the first observable to study jet quenching, i.e. the final state interaction of hard parton showers with the surrounding bulk matter. While its transverse momentum (P_T) dependence of R_AA observed at RHIC was weak and hence never decisive in constraining models, there is now a strong and non-trivial P_T dependence observed at the LHC. This has been a challenge for several models which worked well at RHIC kinematics. However, in more general terms it is also of importance to understand what physical properties of the hard process and the parton-medium interaction are reflected in R_AA(P_T). The results of the work presented here suggest that the two main effects underlying the P_T dependence are the Quantum-Chromodynamics scale evolution of the fragmentation function and the limited distance (set by the typical medium length scale) for which a shower evolves in the medium.

description: Networks of optical waveguides allow for data transmission and sensing applications. Therefore, this technology is a key element for the integration of intelligent systems and structural health monitoring. Optical waveguides are the essential backbone to connect these structures. The flexible and high-resolution manufacturing of waveguides, also on three-dimensional substrates, is accomplished by a combination of two printing processes. In the first step, flexible substrates are conditioned by a printing technology with an adapted flexographic printing mechanism. To produce the optical waveguide itself, the Aerosol-Jet-Printing process of liquid polymer or varnish is used on pre-conditioned areas with hydrophobic or hydrophilic behaviour. Waveguides fabricated by this two-stage process reach parabolic cross sections with a minimum width down to 10 μm. This paper shows the mechanism for the use of the processes and latest results concerning the choice of materials, which allow the operability for this kind of manufacturing. We show the adaption of the local surface energy by the printing technology to achieve a self-configuration of UV varnishes for high-resolution waveguides.

description: Recent research has shown the deep impact of the dynamics of human interactions (or temporal social networks) on the spreading of information, opinion formation, etc. In general, the bursty nature of human interactions lowers the interaction between people to the extent that both the speed and reach of information diffusion are diminished. Using a large database of 20 million users of mobile phone calls we show evidence this effect is not homogeneous in the social network but in fact, there is a large correlation between this effect and the social topological structure around a given individual. In particular, we show that social relations of hubs in a network are relatively weaker from the dynamical point than those that are poorer connected in the information diffusion process. Our results show the importance of the temporal patterns of communication when analyzing and modeling dynamical process on social networks.

description: We show that the formation of a gel by conducting colloidal particles leads to a dramatic enhancement in bulk conductivity, due to inter-particle electron tunneling, combining predictions from molecular dynamics simulations with structural measurements in an experimental colloid system. Our results show how colloidal gelation can be used as a general route to huge enhancements of conductivity, and suggest a feasible way for developing cheap materials with novel properties and low metal content.

description: Genus two curves covering elliptic curves have been the object of study of many articles. For a fixed degree $n$ the subloci of the moduli space $\mathcal M_2$ of curves having a degree $n$ elliptic subcover has been computed for $n=3, 5$ and discussed in detail for $n$ odd; see \cite{Sh1, SV2, Fr, FK}. When the degree of the cover is even the case in general has been treated in \cite{PRS}. In this paper we compute the sublocus of $\mathcal M_2$ of curves having a degree 4 elliptic subcover.

description: Reactivity boundaries that divide the destination and the origin of trajectories are of crucial importance to reveal the mechanism of reactions. We investigate whether such reactivity boundaries can be extracted for higher index saddles in terms of a nonlinear canonical transformation successful for index-one saddles by using a model system with an index-two saddle. It is found that the true reactivity boundaries do not coincide with those extracted by the transformation taking into account a nonlinearity in the region of the saddle even for small perturbations, and the discrepancy is more pronounced for the less repulsive direction of the index-two saddle system. The present result indicates an importance of the global properties of the phase space to identify the reactivity boundaries, relevant to the question of what reactant and product are in phase space, for saddles with index more than one.

description: Precise comparisons of the fundamental properties of matter-antimatter conjugates provide sensitive tests of charge-parity-time (CPT) invariance(1), which is an important symmetry that rests on basic assumptions of the standard model of particle physics. Experiments on mesons(2), leptons(3,4) and baryons(5,6) have compared different properties of matter-antimatter conjugates with fractional uncertainties at the parts-per-billion level or better. One specific quantity, however, has so far only been known to a fractional uncertainty at the parts-per-million level(7,8): the magnetic moment of the antiproton, mu((p) over bar). The extraordinary difficulty in measuring mu((p) over bar) with high precision is caused by its intrinsic smallness; for example, it is 660 times smaller than the magnetic moment of the positron(3). Here we report a high-precision measurement of mu((p) over bar) in units of the nuclear magneton mu N with a fractional precision of 1.5 parts per billion (68% confidence level). We use a two-particle spectroscopy method in an advanced cryogenic multi-Penning trap system. Our result mu((p) over bar) = -2.7928473441(42) mu(N) (where the number in parentheses represents the 68% confidence interval on the last digits of the value) improves the precision of the previous best mu((p) over bar) measurement(8) by a factor of approximately 350. The measured value is consistent with the proton magnetic moment(9), mu((p) over bar) = 2.792847350(9) mu(N), and is in agreement with CPT invariance. Consequently, this measurement constrains the magnitude of certain CPT-violating effects(10) to below 1.8 x 10(-24) gigaelectronvolts, and a possible splitting of the protonantiproton magnetic moments by CPT-odd dimension-five interactions to below 6 x 10(-12) Bohr magnetons(11).
title: The Liberal Arts on Trial: Charles H. Fisher and Red-Scare Politics at Western Washington College of Education, 1933-39
Creators: name: Judd, Ron
Publisher: name: University of Nebraska at Kearney
Year: 2016

description: College president Charles H. Fisher’s transformation of Bellingham State Normal School, a small state teacher’s college, into Western Washington College of Education earned him the overwhelming respect of his peers, faculty, students, and much of the local community. His reward was an abrupt firing by Washington Governor Clarence Martin in 1938. Fisher’s ousting was engineered by a cabal of “anti-communist” citizens led by Frank I. Sefrit, the conservative editor of The Bellingham Herald. The group had ties to a range of “pro-American” groups, including the American Legion, several conservative women’s organizations, local churches, and the Ku Klux Klan. Sefrit called Fisher a communist sympathizer who fostered anti-Americanism, atheism, and “free love” on a campus infected by “Red” academics, many trained at Columbia University. College trustees in 1935 exonerated Fisher, but three years later, acceded to Gov. Clarence Martin’s insistence that Fisher be fired. Subsequent investigations described the firing as politically motivated, raising alarms about infringement of academic freedom during a period of social strife. Existing accounts of the Depression-era incident paint Fisher’s foes as oddball radicals. But the campaign did not occur in a political vacuum. Previously unknown documents about the Fisher case reveal varied personal motivations of Fisher’s foes in a town torn by political rancor, fomented by a vicious, decades-long media war. New evidence also reveals a link between the Fisher case and a concurrent national red-baiting campaign directed at academic institutions across the United States. Additional new evidence suggests that the Fisher dismissal might have been influenced by a separate financial scandal at the college in the 1930s. This study will explore Charles Fisher’s ousting in unprecedented detail, placing it for the first time within the context of a decade of strident, ultra-conservative activism serving as what one historian has dubbed “a bridge between the two Red Scares.”

description: We report the characterisation of printed circuit boards (PCB) metal powder filters and their influence on the effective electron temperature which is as low as 22 mK for a quantum dot in a silicon MOSFET structure in a dilution refrigerator. We investigate the attenuation behaviour (10 MHz- 20 GHz) of filter made of four metal powders with a grain size below 50 um. The room-temperature attenuation of a stainless steel powder filter is more than 80 dB at frequencies above 1.5 GHz. In all metal powder filters the attenuation increases with temperature. Compared to classical powder filters, the design presented here is much less laborious to fabricate and specifically the copper powder PCB-filters deliver an equal or even better performance than their classical counterparts.

description: Protocols used in quantum information and precision spectroscopy rely on efficient internal quantum state discrimination. With a single ion in a linear Paul trap, we implement a novel detection method which utilizes correlations between two detection events with an intermediate spin-flip. The technique is experimentally characterized as more robust against fluctuations in detection laser power compared to conventionally implemented methods. Furthermore, systematic detection errors which limit the Rabi oscillation contrast in conventional methods are overcome.

description: Semiconductor quantum dots are potential building blocks for scalable qubit architectures. Efficient control over the exchange interaction and the possibility of coherently manipulating electron states are essential ingredients towards this goal. We studied experimentally the shuttling of electrons trapped in serial quantum dot arrays isolated from the reservoirs. The isolation hereby enables a high degree of control over the tunnel couplings between the quantum dots, while electrons can be transferred through the array by gate voltage variations. Model calculations are compared with our experimental results for double, triple, and quadruple quantum dot arrays. We are able to identify all transitions observed in our experiments, including cotunneling transitions between distant quantum dots. The shuttling of individual electrons between quantum dots along chosen paths is demonstrated.

description: Related to the recent nuclear release of radioactive ruthenium isotopes in fall 2017, we analyzed air filters from Vienna for irregularities in the (stable) elemental composition of particulate matter from this period. Methods were SEM/EDXS and INAA. For comparison, a reference filter from 2007 and blank filters were used. The chemical fingerprint encompassed 28 elements. The results show no indication for a considerable change in the elemental composition of the suspended matter. For example, no anomalies in the abundance of platinum group elements were found. The results suggest that the release of 106Ru had not been accompanied by a release of detectable amounts of (activatable) stable elements.

description: The electronic properties of the polar interface between insulating oxides is a subject of great current interest. An exciting new development is the observation of robust magnetism at the interface of two non-magnetic materials LaAlO_3 (LAO) and SrTiO_3 (STO). Here we present a microscopic theory for the formation and interaction of local moments, which depends on essential features of the LAO/STO interface. We show that correlation-induced moments arise due to interfacial splitting of orbital degeneracy. We find that gate-tunable Rashba spin-orbit coupling at the interface influences the exchange interaction mediated by conduction electrons. We predict that the zero-field ground state is a long-wavelength spiral and show that its evolution in an external field accounts semi-quantitatively for torque magnetometry data. Our theory describes qualitative aspects of the scanning SQUID measurements and makes several testable predictions for future experiments.

description: Silicones are widely used in medical applications. In ophthalmology, glaucoma drainage devices are utilized if conservative therapies are not applicable or have failed. Long-term success of these devices is limited by failure to control intraocular pressure due to fibrous encapsulation. Therefore, different medical approved silicones were tested in vitro for cell adhesion, cell proliferation and viability of human Sclera (hSF) and human Tenon fibroblasts (hTF). The silicones were analysed also depending on the sample preparation according to the manufacturer's instructions. The surface quality was characterized with environmental scanning electron microscope (ESEM) and water contact angle measurements. All silicones showed homogeneous smooth and hydrophobic surfaces. Cell adhesion was significantly reduced on all silicones compared to the negative control. Proliferation index and cell viability were not influenced much. For development of a new glaucoma drainage device, the silicones Silbione LSR 4330 and Silbione LSR 4350, in this study, with low cell counts for hTF and low proliferation indices for hSF, and silicone Silastic MDX4-4210, with low cell counts for hSF and low proliferation indices for hTF, have shown the best results in vitro. Due to the high cell adhesion shown on Silicone LSR 40, 40,026, this material is unsuitable.

Zwischen den Übergangsverläufen und Zukunftsperspektiven von jungen Menschen, die ihr Abitur in einem acht- oder neunjährigen Bildungsgang erworben haben, lassen sich in der Befragung keine Unterschiede identifizieren.
Kritik am G8-Modell wird in der Befragung vor allem mit einer erhöhten zeitlichen Belastung während der Schulzeit begründet. Diese Problematik wird allerdings von ehemaligen G9er/inne/n wesentlich ausgeprägter vorgetragen als von den G8er/inne/n selbst.
Negativ wird der bisherige Bildungsweg nach dem Abitur vor allem von Befragten bewertet, die ihre aktuelle Studien- oder Ausbildungssituation als unbefriedigend empfinden. Die zusätzlichen Erfahrungen durch „Umwege“ werden hingegen überwiegend positiv betrachtet.
Die Kommunikation mit den Eltern spielt für den Prozess der Orientierung eine große Rolle. Finanzielle Restriktionen sind weniger für die grundsätzliche Entscheidung für oder gegen ein Studium von Bedeutung als für die Auswahlmöglichkeiten, die vor allem durch hohe Wohnkosten beschränkt werden.
Die Berufs- und Studienorientierung in der Oberstufe ist ausbaufähig. Dabei kommt es vor allem darauf an, Konzepte zu entwickeln, die den individuell sehr unterschiedlichen Bedürfnissen der Schüler/innen gerecht werden.

description: We focus on the Gibbs free energy $ΔG$ for nucleating a droplet of the stable phase (e.g. solid) inside the metastable parent phase (e.g. liquid), close to the first-order transition temperature. This quantity is central to the theory of homogeneous nucleation, since it superintends the nucleation rate. We recently introduced a field theory describing the dependence of $ΔG$ on the droplet volume $V$, taking into account besides the microscopic fuzziness of the droplet-parent interface, also small fluctuations around the spherical shape whose effect, assuming isotropy, was found to be a characteristic logarithmic term. Here we extend this theory, introducing the effect of anisotropy in the surface tension, and show that in the limit of strong anisotropy $ΔG(V)$ once more develops a term logarithmic on $V$, now with a prefactor of opposite sign with respect to the isotropic case. Based on this result, we argue that the geometrical shape that large solid nuclei mostly prefer could be inferred from the prefactor of the logarithmic term in the droplet free energy, as determined from the optimization of its near-coexistence profile.

description: In this work, we report the dielectric properties of Single wall Carbon Nanotubes (SWCNTs)-based phantom that is mainly composed of gelatin and water. The fabricated gelatin-based phantom with desired dielectric properties was fabricated and doped with different concentrations of SWCNTs (e.g., 0%, 0.05%, 0.10%, 0.15%, 0.2%, 0.4% and 0.6%). The dielectric constants (real ε′ and imaginary ε′′) were measured at different positions for each sample as a function of frequency (0.5–20GHz) and concentrations of SWCNTs and their averages were found. The Cole–Cole plot (ε′ versus ε′′) was obtained for each concentration of SWCNTs and was used to obtain the static dielectric constant εs, the dielectric constant at the high limit of frequency ε∞ and the average relaxation time τ. The measurements showed that the fabricated samples are in good homogeneity and the SWCNTs are dispersed well in the samples as an acceptable standard deviation is achieved. The study showed a linear increase in the static dielectric constant εs and invariance of the average relaxation time τ and the value of ε∞ at room temperature for the investigated concentrations of SWCNTs.

description: In this paper we propose an experiment designed to observe a general-relativistic effect on single photon interference. The experiment consists of a folded Mach-Zehnder interferometer, with the arms distributed between a single Earth orbiter and a ground station. By compensating for other degrees of freedom and the motion of the orbiter, this setup aims to detect the influence of general relativistic time dilation on a spatially superposed single photon. The proposal details a payload to measure the required effect, along with an extensive feasibility analysis given current technological capabilities.
title: Making Sense with Math: an Introduction to Math for People in College
Creators: name: Ronca, Roxane
Publisher: name: Western Washington University
Year: 2019

description: Most math books for college students start out reviewing “rules” in an introductory chapter. The review usually goes like this: here are the “rules”, here are some examples of using those “rules” and here are 10 to 100 exercises where you will practice using those “rules” and then you’ll be tested on them.

The problem with that approach, even if it seems familiar and comfortable to you, is that people learn, in part, by connecting new ideas and perspectives to what they already understand, and correcting any previous misunderstandings. This process takes time and effort. Memorizing rules to quickly retrieve them won’t be useful to you when you are trying to apply mathematics to an unfamiliar situation.

This book will help you grow the habits of mind that will allow you to make problems easier through the use of mathematics.

description: Adaptive resolution schemes allow the simulation of a molecular fluid treating simultaneously different subregions of the system at different levels of resolution. In this work we present a new scheme formulated in terms of a global Hamiltonian. Within this approach equilibrium states corresponding to well defined statistical ensembles can be generated making use of all standard Molecular Dynamics or Monte Carlo methods. Models at different resolutions can thus be coupled, and thermodynamic equilibrium can be modulated keeping each region at desired pressure or density without disrupting the Hamiltonian framework.

description: Der vorliegende Artikel handelt von einer feministischen Lesung von zwei mittelpersischen Texten. Die inhaltliche Analyse fokussiert sich auf die religiösen Gesetze im Bereich der Menstruation, Unreinheit und deren sozialen Auswirkungen bzw. Einschränkungen. Die linguistische Analyse zeigt andererseits, wie die Sprache durch Versetzung der Frau in ein bipolares System von "richtig/falsch" die soziale Kontrolle über den weiblichen Körper institutionalisiert und gerechtfertigt. بازخوانی فمینیستی دو متن فارسی میانه آنیتا کریمی این مقاله به بررسی دو متن فارسی میانه "شایست ناشایست" و "ارداویراف نامه" از نگاه فمینیستی می‌پردازد. تحلیل در سطح محتوایی بر احکام دینی مربوط به دوره‌ی دشتان زن، ناپاکی و محدویت‌های اجتماعی ناشی از ناپاکی در این دوره متمرکز است. تحلیل در سطح زبانی نشان می‌دهد چگونه زبان با قرار دادن زن در نظام دو قطبی "درست / نادرست" کنترل اجتماعی بر بدن او در جامعه را نهادینه می‌کند.
title: Women of Color in Speculative Fiction: An Annotated Bibliography of Authors
Creators: name: Marrall, Rebecca
Publisher: name: Western Washington University
Year: 2016

description: Women of Color in Speculative Fiction: An Annotated Bibliography is tertiary electronic resource which focuses upon authors who are women of color (i.e., non-Caucasian) and who write speculative fiction for adult and young adult audiences. Examples of these authors include Octavia Butler, N. K. Jemisin, Daina Chaviano, Jewelle Gomez, and Malinda Lo. For some background, “speculative fiction” is an umbrella term for science fiction, fantasy, and some horror, all of which have literary and popular merit (Urbanski 2007). Historically, this field has been dominated by male authors of largely Caucasian descent; women and/or people of color have not been equitably represented in this genre. Completed in October 2016, the purpose of this annotated bibliography is to raise awareness about underrepresented authors who bring unique perspectives to this genre.

description: Legumes have the unique ability to host nitrogen-fixing Rhizobium bacteria as symbiosomes inside root nodule cells. To get insight into this key process, which forms the heart of the endosymbiosis, we isolated specific cells/tissues at different stages of symbiosome formation from nodules of the model legume Medicago truncatula using laser-capture microdissection. Next, we determined their associated expression profiles using Affymetrix Medicago GeneChips. Cells were collected from the nodule infection zone divided into a distal (where symbiosome formation and division occur) and proximal region (where symbiosomes are mainly differentiating), as well as infected cells from the fixation zone containing mature nitrogen fixing symbiosomes. As non-infected cells/tissue we included nodule meristem cells and uninfected cells from the fixation zone. Here, we present a comprehensive gene expression map of an indeterminate Medicago nodule and selected genes that show specific enriched expression in the different cells or tissues. Validation of the obtained expression profiles, by comparison to published gene expression profiles and experimental verification, indicates that the data can be used as digital "in situ''. This digital "in situ'' offers a genome-wide insight into genes specifically associated with subsequent stages of symbiosome and nodule cell development, and can serve to guide future functional studies.

description: Magnetic beads (MBs) are versatile tools for the purification, detection, and quantitative analysis of analytes from complex matrices. The superparamagnetic property of magnetic beads qualifies them for various analytical applications. To provide specificity, MBs can be decorated with ligands like aptamers, antibodies and peptides. In this context, aptamers are emerging as particular promising ligands due to a number of advantages. Most importantly, the chemical synthesis of aptamers enables straightforward and controlled chemical modification with linker molecules and dyes. Moreover, aptamers facilitate novel sensing strategies based on their oligonucleotide nature that cannot be realized with conventional peptide-based ligands. Due to these benefits, the combination of aptamers and MBs was already used in various analytical applications which are summarized in this article. © 2018 by the authors.

1-O-trans-Cinnamoyl-β-ᴅ -glucopyranose: Alcohol Cinnamoyltransferase Activity in Fruits of Cape Gooseberry (Physalis peruviana L.)

description: Methyl and ethyl cinnamate are aroma volatiles frequently occurring in fruits. Evidence was obtained that the enzymatic transfer of cinnamic acid to endogenous alcohols present in fruits (methanol, ethanol. 1-propanol) depended on energy-rich 1-O-glycosyl esters of cinnamic acid which served as acyl donor molecules. A putative l-O-trans-cinnamoyl-β-D-gluco-pyranose: alcohol cinnamoyltransferase from cape gooseberry (Physalis peruviana L.) was active towards l-O-trans-cinnamoyl-β-D-glucopyranose and l-O-trans-cinnamoyl-β-D-gentio-biose. The enzyme was purified 290-fold by a protocol including ammonium sulphate precipitation, solubilization by Triton X-100, gel permeation and affinity chromatography on conca-navalin A. The acidic glycoprotein (pI = 4.8) most probably is membrane bound. The distribution of alcohol cinnamoyltransferase activity in gel chromatography fractions suggests a native Mrof 75,000. For l-O-trans-cinnamoyl-β-D-glucopyranose, an apparent Kmof 69 was determined. At pH > 6.0, non-enzymatic transesterification superposes the enzymatic transformation.
Convergence and Quasi-Optimality of Adaptive FEM with Inhomogeneous Dirichlet Data

description: We consider the solution of a second order elliptic PDE with inhomogeneous Dirichlet data by means of adaptive lowest-order FEM. As is usually done in practice, the given Dirichlet data are discretized by nodal interpolation. As model example serves the Poisson equation with mixed Dirichlet-Neumann boundary conditions. For error estimation, we use an edge-based residual error estimator which replaces the volume residual contributions by edge oscillations. For 2D, we prove convergence of the adaptive algorithm even with quasi-optimal convergence rate. For 2D and 3D, we show convergence if the nodal interpolation operator is replaced by the L^2-projection or the Scott-Zhang quasi-interpolation operator. As a byproduct of the proof, we show that the Scott-Zhang operator converges pointwise to a limiting operator as the mesh is locally refined. This property might be of independent interest besides the current application. Finally, numerical experiments conclude the work.

description: Microarray technologies are state of the art in biological research, which requires fast genome, proteome and transcriptome analysis technologies. Often antibodies are applied in protein microarrays as proteomic tools. Since the generation of antibodies against toxic targets or small molecules including organic compounds remains challenging the use of antibodies may be limited in this context. In contrast to this, aptamer microarrays provide alternative techniques to circumvent these limitations. In this article we review the latest developments in aptamer microarray technology. We discuss similarities and differences between DNA and aptamer microarrays and shed light on the post synthesis immobilization of aptamers including corresponding effects on the microarray performance. Finally, we highlight current limitations and future prospects of aptamer microarray technology.
