description: Momentum sum rule can be used as an inequality to estimate the lower and upper bounds of the momentum fractions of quarks and gluons in a model of proton valid in a limited \textit{x} range. We compute such bounds in a self-similarity based model of proton structure function valid in the range $ 6.2\times 10^{-7} \leq x \leq 10^{-2} $. The results conform to the asymptotic QCD expectations.

description: We derive the Lie and the Noether conditions for the equations of motion of a dynamical system in a $n-$dimensional Riemannian space. We solve these conditions in the sense that we express the symmetry generating vectors in terms of the special projective and the homothetic vectors of the space. Therefore the Lie and the Noether symmetries for these equations are geometric symmetries or, equivalently, the geometry of the space is modulating the motion of dynamical systems in that space. We give two theorems which contain all the necessary conditions which allow one to determine the Lie and the Noether symmetries of a specific dynamical system in a given Riemannian space. We apply the theorems to various interesting situations covering Newtonian 2d and 3d systems as well as dynamical systems in cosmology.

description: Context. It has been proposed that the temporal coincidence of a gamma-ray burst (GRB) and a type Ib/c supernova (SN) can be explained with the concept of induced gravitational collapse (IGC), induced by the matter ejected from an SN Ib/c accreting onto a neutron star (NS). The NS is expected to reach the critical mass necessary for it to collapse to a black hole (BH) and emit a GRB. We found a standard luminosity light curve behavior in the late-time X-ray emission of this subclass of GRBs. Aims. We test if this standard behavior in the luminosity found in this subclass of GRBs can become a redshift estimator of these sources. Methods. We selected a sample of GRBs that belong to this subclass of IGC GRBs associated to an SN (IGC GRB-SN sources). These sources have an isotropic energy $E_{iso} > 10^{52}$ erg and their cosmological redshifts are in the range of $z = 0.49-1.261$. We focused on the corresponding X-ray luminosity light curves. Results. We find that all GRBs of the sample with measured redshift present a standard luminosity late-time light curve in the $0.3-10$ keV rest-frame energy range. We used these results to estimate the GRB redshift of the sample without a measured redshift and found results consistent with other possible redshift indicators. Conclusions. The standard late-time X-ray luminosity light curve of all GRBs of the sample shows a common physical mechanism in this particular phase of the X-ray emission, possibly related to the creation of the NS from the SN process. This scaling law moreover represents strong evidence of very low or even absent beaming in this late phase of the X-ray afterglow emission process. This could be a fundamental tool for estimating the redshift of GRBs that belong to this subclass of events. We are currently expanding this subclass of GRBs to further verify the universal validity of this new redshift estimation method.

Three Dimensional Mirror Symmetry and Partition Function on $S^3$

Year: 2013
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We provide non-trivial checks of $\mathcal{N}=4, D=3$ mirror symmetry in a large class of quiver gauge theories whose Type IIB (Hanany-Witten) descriptions involve D3 branes ending on orbifold/orientifold 5-planes at the boundary. From the M-theory perspective, such theories can be understood in terms of coincident M2 branes sitting at the origin of a product of an A-type and a D-type ALE (Asymtotically Locally Euclidean) space with G-fluxes. Families of mirror dual pairs, which arise in this fashion, can be labeled as $(A_{m-1},D_n)$, where $m$ and $n$ are integers. For a large subset of such infinite families of dual theories, corresponding to generic values of $n\geq 4$, arbitrary ranks of the gauge groups and varying $m$, we test the conjectured duality by proving the precise equality of the $S^3$ partition functions for dual gauge theories in the IR as functions of masses and FI parameters. The mirror map for a given pair of mirror dual theories can be read off at the end of this computation and we explicitly present these for the aforementioned examples. The computation uses non-trivial identities of hyperbolic functions including certain generalizations of Cauchy determinant identity and Schur's Pfaffian identity, which are discussed in the paper.

description: Mittelspannungsschaltanlagen ermöglichen in Energieversorgungsnetzen eine Änderung der Netztopologie, bzw. den selektiven Schutz des Netzes im Fehlerfall. Schalthandlungen in den Mittelspannungskreisen verursachen Vorund Rückzündungslichtbögen, die transiente Überspannungen mit kurzen Anstiegszeiten zur Folge haben. Diese breitbandigen Transienten koppeln auf die Niederspannungsseite über und wirken dort auf die elektronischen Schutzund Steuereinheiten (engl. intelligent electronic devices, kurz: IEDs) ein. Um das Risiko einer Fehlfunktion des Netzschutzes zu minimieren sind für die analogen Eingänge eines IEDs spezielle Typprüfungen vorgesehen. Durch die zunehmende Verbreitung von elektronischen Messwandlern nach IEC 60044-8, wie z.B. Rogowski-Sensoren, ergeben sich Unsicherheiten in Bezug auf das genormte Prüfverfahren. In diesem Beitrag werden die Unterschiede zwischen den konventionellen Stromwandlern (engl. current transformer, kurz: CT) und der neuen Technik vorgestellt. Beide Technologien werden hinsichtlich der Koppelpfade für Störgrößen verglichen. Anschließend werden das genormte Prüfverfahren und die Probleme bei dessen Anwendung auf IEDs mit elektronischen Messwandlern beschrieben. Es wird ein alternatives Prüfverfahren vorgeschlagen, dass die reale Beanspruchung für hochohmige Eingänge besser nachbildet. Die Vergleichbarkeit der Störpegel bei Prüfung und realem Schaltanlagenbetrieb wird dabei im Zeitund Frequenzbereich gezeigt.
title: Using Geographically Weighted Regression Models to Analyze Crash Harm
Creators: name: Zheng, Libin
Publisher: name: Old Dominion University Libraries
Year: 2009

description: Society pays a high cost for collisions in terms of property damage, injuries and loss of life. This paper has two objectives. One is to examine various factors associated with harm caused by highway collisions. Both global OLS and local GWR models are provided to identify specific variables influencing crash harm. Another objective is to demonstrate the use of a Geographically Weighted Regression (GWR) method in this complex safety problem, which can estimate models for each crash location and show spatial variation. The results show that the GWR model is a significant improvement on the OLS model; the test for non-stationarity shows the relationship between angle collision, fixed object off road collision, road width and percentage of truck traffic and crash harm change significantly over space; four maps of local estimator of these four variables and detailed analysis are provided to exhibit the considerable spatial variation. The results provide valuable information on high-risk factors associated with collision harm and the spatial characteristics for these associations.

description: Due to the rising prevalence of metabolic disorders, including type 2 diabetes (T2DM), new prevention and treatment strategies are needed. The aim was to examine the effect of astaxanthin (AST) on the major regulatory metabolism pathway SIRT-MAPK and fatty acid (FA) profile of plasma in patients with T2DM. This clinical trial included 68 T2DM patients randomly assigned to receive 10 mg/day of oral AST (n = 34) or placebo (n = 33) for 12 weeks. The expression level of SIRT1, AMPK activity, and the level of fatty acids in the serum were examined. The results showed that AST could modify the serum levels of saturated fatty acids (SFA) and polyunsaturated fatty acids (PUFA), particularly that of Arachidonic acid, from 11.31±0.35 to 8.52±0.72 %. Also, AST increased the expression and activity levels of SIRT1 and AMPK, respectively. Pearson analysis also revealed a significant association between AMPK activity and Linoleic acid serum (LA) levels (~ -0.604, p~0.013). AST can modify the FA profile of plasma by inducing metabolizing cells to uptake them. Also, it can activate the SIRT-AMPK pathway related to metabolism regulation.

description: Symmetry protected topological phase is one type of nontrivial quantum disordered many-body state of matter. In this work we study one class of symmetry protected topological phases in two dimensional space, with both PSU(N) and time reversal symmetry. These states can be described by a principal chiral model with a topological Theta-term. As long as the time-reversal symmetry and PSU(N) symmetry are both preserved, the 1+1 dimensional boundary of this system must be either gapless or degenerate. We will also construct a wave function of a spin-1 system on the honeycomb lattice, which is a candidate for the symmetry protected topological phase with both SO(3) and time-reversal symmetry.

description: Industrial PERC cell process flows typically apply the polishing of the rear side after texturing as well as the edge isolation after POCl3 diffusion. In this paper, we present a novel single step polishing process which we apply post double sided texturing and diffusion in order to remove the rear emitter and to reduce the rear surface roughness. One challenge is to minimize the etch back of the front side emitter during rear side polishing due to the reactive gas phase of the polishing process. By optimizing the polishing process, we are able to limit the increase of the emitter sheet resistance below 5 Ω/sq. However, the wet cleaning post polishing contributes an additional 20 Ω/sq emitter sheet resistance increase which is subject to further optimization. We compensate the emitter sheet resistance increase due to wet cleaning by applying a 45 Ω/sq POCl3 diffusion instead of a 60 Ω/sq diffusion. The resulting PERC solar cells with polished rear surface post texture and diffusion show conversion efficiencies up to 19.6% which is comparable to the reference PERC cells which apply a rear protection layer instead of a polishing process.

description: In nonlocal general relativity, linearized gravitational waves are damped as they propagate from the source to the receiver in the Minkowski vacuum. Nonlocal gravity is a generalization of Einstein's theory of gravitation in which nonlocality is due to the gravitational memory of past events. That nonlocal gravity is dissipative is demonstrated in this paper within certain approximation schemes. The gravitational memory drag leads to the decay of the amplitude of gravitational waves given by the exponential damping factor exp (-t/τ), where $τ$ depends on the kernel of nonlocal gravity. The damping time $τ$ is estimated for gravitational waves of current observational interest and is found to be of the order of, or longer than, the age of the universe.

description: Collagen is a main component of the extracellular matrix. It is often used in medical applications to support tissue regeneration, hemostasis, or wound healing. Due to different sources of collagen, the properties and performance of available products can vary significantly. In this in vitro study, a comparison of seven different collagen matrices derived from bovine, equine, and porcine sources was performed. As performance indicators, the scaffold function for fibroblasts and platelet aggregation were used. We found strong variation in platelet aggregation and fibroblast growth on the different collagen materials. The observed variations could not be attributed to species differences alone, but were highly dependent on differences in the manufacturing process.

description: The problem of power allocation is studied for a multiple-input multiple-output (MIMO) decode-and-forward (DF) two-way relaying system consisting of two source nodes and one relay. It is shown that achieving maximum sum-rate in such a system does not necessarily demand the consumption of all available power at the relay. Instead, the maximum sum-rate can be achieved through efficient power allocation with minimum power consumption. Deriving such power allocation, however, is nontrivial due to the fact that it generally leads to a nonconvex problem. In Part I of this two-part paper, a sum-rate maximizing power allocation with minimum power consumption is found for MIMO DF two-way relaying, in which the relay optimizes its own power allocation strategy given the power allocation strategies of the source nodes. An algorithm is proposed for efficiently finding the optimal power allocation of the relay based on the proposed idea of relative water-levels. The considered scenario features low complexity due to the fact that the relay optimizes its power allocation without coordinating the source nodes. As a trade-off for the low complexity, it is shown that there can be waste of power at the source nodes because of no coordination between the relay and the source nodes. Simulation results demonstrate the performance of the proposed algorithm and the effect of asymmetry on the considered system.

description: YouSound is a social science research project that studies symphonic music education organizations centred on the inclusion of minor migrants and refugees in Europe. We have chosen two organizations in different countries to serve as case studies: the Dream Orchestra in Sweden, and El Sistema Greece. In 2022 and 2023, we are visiting both countries, applying ethnographic methods to better grasp the complexity of interactions between multicultural human beings in these music education contexts. YouSound is a team of researchers from Portugal. This specific research project demanded something more than the “solo ethnographer” in the field. We wanted a cross between “ways of seeing” (Berger 1972) combining the skills of the ethnographer who uses a set of qualitative methods to interpret everyday life in a given context; and those of the graphic ethnographer, whose eyes may perceive social reality from a different and complementary angle (Cabau, Almeida, Mapril 2018). Moreover, we approach fieldwork by using art-based research methods (Leavy 2015, Lenette 2019, Pink 2015), specifically music and illustration, which also serve as complementary tools of expression for the social actors involved in the programs (teachers, students, parents etc.…). YouSound Zines will be published on the fieldwork undertaken in Sweden and in Greece with two editions issued for each. Adding to standard outputs (articles, books, communications), the Zines will be sharing some of the graphic illustrations made by Beatriz Machado in each country. We also want to give back and engage with the minor d students, the parents, the teachers, and the directors who kindly shared their musical world. Thank you for the welcome! Just as for poetry reading, the observation of drawings resulting from graphic ethnography requires that we stay open and alive to seeing between the lines.

description: Plant performance is significantly influenced by prevailing light and temperature conditions during plant growth and development. For plants exposed to natural fluctuations in abiotic environmental conditions it is however laborious and cumbersome to experimentally assign any contribution of individual environmental factors to plant responses. This study aimed at analyzing the interplay between light, temperature and internode growth based on model approaches. We extended the light-sensitive virtual plant model L-Cucumber by implementing a common Arrhenius function for appearance rates, growth rates, and growth durations. For two greenhouse experiments, the temperature-sensitive model approach resulted in a precise prediction of cucumber mean internode lengths and number of internodes, as well as in accurately predicted patterns of individual internode lengths along the main stem. In addition, a system's analysis revealed that environmental data averaged over the experimental period were not necessarily related to internode performance. Finally, the need for a species-specific parameterization of the temperature response function and related aspects in modeling temperature effects on plant development and growth is discussed.

description: Karen Pashby, Professor of Global Citizenship Education at Manchester Metropolitan University, docent at University of Helsinki, and Adjunct Professor at University of Alberta, is a renowned researcher and educator in the field of Global Citizenship Education (GCE). Her work draws on de/post/anti-colonial theoretical resources to support critically reflexive practices in GCE in ‘Global North’ contexts. In this interview, Pashby emphasizes the aspirational and contested paradox of GCE, aiming to engage learners in thinking about ethical relations of rights and responsibilities. She highlights the need for multiple transformations in the structures that frame our relations as cohabitants of the planet, while at the same time warning about the risk of the tendency towards solutionism. As a critical GCE scholar, Pashby highlights that learners and educators must acknowledge they are both part of the problem and the solution, and therefore, build on critical reflexivity and deep thinking to understand their ethical relations.

description: We analyze in situ measurements of solar wind velocity obtained by Advanced Composition Explorer (ACE) spacecraft and Helios spacecraft during the years 1998-2012 and 1975-1983 respectively. The data belong to mainly solar cycle 23 (1996-2008) and solar cycle 21 (1976-1986) respectively. We use Directed Horizontal Visibility graph (DHVg) algorithm and estimate a graph functional, namely, the degree distance (D) as the Kullback-Leibler divergence (KLD) argument to understand time irreversibility of solar wind time series. We estimate this degree distance irreversibility parameter for these time series at different phases of solar activity cycle. Irreversibility parameter is first established for known dynamical data and then applied for solar wind velocity time series. It is observed that irreversibility in solar wind velocity fluctuations show similar behaviour at 0.3 AU (Helios data) and 1 AU (ACE data). Moreover it changes over the different phases of solar activity cycle.

description: Using Gelfand-Levitan theory on a half line, we construct a vessel for the class of potentials, whose spectral functions satisfy a certain regularity assumption. When the singular part of the spectral measure is absent, we construct a canonical model of the vessel. Finally, evolving the constructed vessel, we solve the Korteweg de Vries equation on the half line, coinciding with the given potential for $t=0$. It is shown that the initial value for x=0 is prescribed by this construction, but can be perturbed using an "orthogonal" to the problem measure. The results, presented in this work 1. include formulas for the ingredients of the Gelfand-Levitan equation, 2. are shown to be general in the sense that NLS, Canonical systems and many more equations can be solved using theory of vessels, analogously to Zacharov-Shabath scheme, 3. present a generalized inverse scattering theory on a line for potentials with singularities using pre-vessels, 4. present the tau function and its role.

description: Die elektronischen Hochvoltkomponenten des Traktionssystems von Elektrofahrzeugen erzeugen Störungen von hoher Intensität, die gegebenenfalls die fehlerfreie Funktion anderer Elektroniksysteme im Fahrzeug beeinflussen. Die EMV-Anforderungen im Fahrzeug können bisher nur erfüllt werden, wenn diese Gesamtsysteme aufwendig geschirmt sind. Nachfolgend werden Untersuchungen vorgestellt, bei denen die Schirmung eines Hochvoltsystems, bestehend aus Umrichter, Motor, Spannungsquelle und Ansteuerung, durch innovative Filter in den Traktionsoder Phasenleitungen ersetzt wird. Dazu wird ein Messaufbau nach CISPR 25 [1] gezielt abgeändert. Der dadurch mögliche Verzicht auf rotierende Komponenten durch die Entwicklung einer Nachbildung für die E-Maschine führt zu signifikant vereinfachten Randbedingungen bei den Messungen ohne die Aussagekraft der Ergebnisse zu beeinflussen. Die entwickelte Einrichtung lässt sich unabhängig von dem eingesetzten EUT geschirmt und ungeschirmt betreiben. Die Einflussparameter auf die Störaussendung können damit gezielt analysiert werden. Zielstellung ist der Vergleich der Störaussendung bei Schirmung oder Filterung unter applikationsnahen Bedingungen. Für den Messaufbau wurde ein EMV-geeignetes Netzwerksimulationsmodell entwickelt. Es wird die beispielhaft auf Randbedingungen beim Filterentwurf eingegangen und die erreichbare Störunterdrückung an Bespielen dargelegt. Die Arbeiten erfolgten in im Auftrag der Forschungsvereinigung Automobiltechnik e.V. (FAT) des Verbandes der Automobilindustrie e. V. (VDA).

description: Kiruna-type iron oxide-apatite (IOA) deposits are important sources for Fe, necessary for steel production, and other elements such as REE, crucial for new technologies. IOA deposits occur worldwide (Sweden, Chile, USA, China, Iran etc.) and range in age from Late Archean (2.5 Ga) to the present. However, their formation is still under debate. Hypotheses vary from a (magmatic-) hydrothermal origin to direct crystallization from an immiscible Fe-rich melt. In order to investigate which hypotheses works best, we measured trace element concentrations and Fe-isotope ratios in-situ in magnetites (Fe3O4) from the Cretaceous Los Colorados IOA deposit (~350 Mt Fe) in the Chilean Iron Belt. Analyses showed that magnetite cores have an igneous texture and chemistry, while the surrounding magnetite rims indicate lower temperature (magmatic-) hydrothermal formation conditions. Since a coactive cooperation between both processes could not be explained by one of the existing models, we developed a completely novel formation model for Kiruna-type IOA deposits. In our proposed scenario the decompression of an oxidized, andesitic and volatile-rich magma, typical for arc-volcanism, results in degassing of volatiles such as H2O and Cl. The exsolved fluid bubbles are expected to nucleate preferentially on surfaces of oxide crystals such as magnetite where surface tension is lower. The bulk density of these bubble-magnetite pairs is expected to be lower than the surrounding magma and will thus float upwards as a bubble-magnetite suspension that is additionally enriched in dissolved Fe due to complexation with Cl. This suspension will cause the formation of massive magnetite deposits in regional-scale transcurrent faults with magmatic-hydrothermal as well as with igneous characteristics. High temperature decompression experiments confirmed that the flotation model is physically possible and clearly showed upward accumulation of magnetite upon decompression and fluid exsolution in contrast to gravitational settling of these dense minerals expected without exsolved fluids. This flotation scenario is in agreement with the geochemical and isotopic signatures observed at Los Colorados and other Kiruna-type IOA deposits. Mineral flotation on exsolved fluid bubbles may also change classical views on crystal fractionation and thus the formation of monomineralic layers in mafic layered intrusions (e.g., Skaergaard, Bushveld complex), where dense magnetite layers overlie less dense anorthosite layers.

description: This contribution deals with the process-machine interaction while forming parts by sheet-bulk metal forming. The goal of this process is to form complex functional elements, such as gearing and carrier elements, by means of controlled thickening of the metal sheet. The high process forces in vertical as well as in horizontal direction to form these elements, cause displacements of the tool and press components, which lead to parts defects retroactively. This work demonstrates these challenges with regard to manufacturing of asymmetrical parts and introduces a suitable approach to represent the process-machine interaction by modelling.

description: Cell-cell fusion is essential for sexual reproduction and occurs when the lipid membranes of two distinct cells merge into one continuous bilayer. While in recent years some general aspects have been uncovered, the underlying molecular mechanism remains poorly understood. Mating of haploid Saccharomyces cerevisiae cells of the opposite sex provides an ideal model system to study plasma membrane (PM) fusion in eukaryotic organisms. In this work, a multicolor flow cytometry assay based on fluorescent complementation (BiFC) of split-GFP was adapted to screen a customized yeast knockout library (YKO) for fusion defects. In total, 28 mutants were identified that exhibited fusion levels at least as defective as .prm1, a known regulator of this step. Like .prm1, the majority displayed a bilateral fusion defect. The remaining part of the work focused on an in-depth analysis of select gene of interest (GOI) mutants. Investigations of synergistic relationships in trans revealed an interaction network operating during PM fusion involving at least four independent yet partially overlapping fusion pathways. Previously two pathways with ERG6 and PRM1 have been reported. VMA2, a gene encoding a subunit of the vacuolar membrane ATPase (V-ATPase), was revealed in this work to operate on a third pathway. The findings show that the V-ATPase i) promotes cell fusion indirectly by acidifying endomembrane organelles, ii) facilitates both cell wall (CW) remodeling and PM fusion stages approximately equally, and iii) synergistically interacts with 12 other genes identified in this study. CAX4 was identified to operate on the fourth pathway and the only novel gene found to synergize with PRM1. Further investigations revealed that Prm1p was less abundant in a .cax4 sensitized background, while its localization is not affected. Finally, this work discovered that several subunits of the RNA polymerase II mediator complex are involved in promoting early and late stages of yeast mating. The deletion of subunits leads to varying degrees of defects in cell pairing and pheromone secretion as well as CW remodeling and PM fusion. Together, these findings suggest that the mediator complex acts as a master regulator of cell fusion perhaps by synchronizing the expression of mating genes needed at crucial time points starting from the digestion of the CW up to the merging of the PMs.

description: We report on synoptic observations at 3.6 and 4.5micron of young stellar objects in IC 348 with 38 epochs covering 40 days. We find that among the detected cluster members, 338 at [3.6] and 269 at both [3.6] and [4.5], many are variable on daily to weekly timescales with typical fluctuations of ~0.1 mag. The fraction of variables ranges from 20% for the diskless pre-main sequence stars to 60% for the stars still surrounded by infalling envelopes. We also find that stars in the exposed cluster core are less variable than the stars in the dense, slightly younger, south-western ridge. This trend persists even after accounting for the underlying correlation with infrared SED type, suggesting that the change in variable fraction is not simply a reflection of the change in relative fraction of class I vs. class II sources across the cloud, but instead reflects a change in variability with age. We also see a strong correlation between infrared variability and X-ray luminosity among the class II sources. The observed variability most likely reflects large changes in the structure of the inner wall located at the dust sublimation radius. We explore the possibility that these structural perturbations could be caused by a hot spot on the star heating dust above the sublimation temperature, causing it to evaporate rapidly, and increasing the inner radius for a portion of the disk. Under a number of simplifying assumptions we show that this model can reproduce the size and timescale of the 3.6 and 4.5micron fluctuations. Regardless of its source, the infrared variability indicates that the inner disk is not a slowly evolving entity, but instead is a bubbling, warped, dented mass of gas and dust whose global size and shape fluctuate in a matter of days.
