description: Micelle formation in binary mixtures of surfactants is studied using a coarse-grained molecular simulation. When a vesicle composed of lipid and detergent types of molecules is ruptured, a disk-shaped micelle, the bicelle, is typically formed. It is found that cup-shaped vesicles and bicelles connected with worm-like micelles are also formed depending on the surfactant ratio and critical micelle concentration. The obtained octopus shape of micelles agree with those observed in the cryo-TEM images reported in [S. Jain and F. S. Bates, Macromol. 37, 1511 (2004).]. Two types of connection structures between the worm-like micelles and the bicelles are revealed.

description: Graphene, a flat monolayer of carbon atoms packed tightly into a two dimensional hexagonal lattice, has unusual electronic properties which have many promising nanoelectronic applications. Recent Low Energy Electron Microscopy (LEEM) experiments show that the step edge velocity of epitaxially grown 2D graphene islands on Ru(0001) varies with the fifth power of the supersaturation of carbon adatoms. This suggests that graphene islands grow by the addition of clusters of five atoms rather than by the usual mechanism of single adatom attachment. We have carried out Kinetic Monte Carlo (KMC) simulations in order to further investigate the general scenario of epitaxial growth by the attachment of mobile clusters of atoms. We did not seek to directly replicate the Gr/Ru(0001) system but instead considered a model involving mobile tetramers of atoms on a square lattice. Our results show that the energy barrier for tetramer break up and the number of tetramers that must collide in order to nucleate an immobile island are the important parameters for determining whether, as in the Gr/Ru(0001) system, the adatom density at the onset of island nucleation is an increasing function of temperature. A relatively large energy barrier for adatom attachment to islands is required in order for our model to produce an equilibrium adatom density that is a large fraction of the nucleation density. A large energy barrier for tetramer attachment to islands is also needed for the island density to dramatically decrease with increasing temperature. We show that islands grow with a velocity that varies with the fourth power of the supersaturation of adatoms when tetramer attachment is the dominant process for island growth.

description: We analysed all archival RXTE observations of the neutron-star low-mass X-ray binary 4U 1636-53 up to May 2010. In 528 out of 1280 observations we detected kilohertz quasi-periodic oscillations (kHz QPOs), with ~ 65% of these detections corresponding to the so-called lower kHz QPO. Using this QPO we measured, for the first time, the rate at which the QPO frequency changes as a function of QPO frequency. For this we used the spread of the QPO frequency over groups of 10 consecutive measurements, sampling timescales between 320 and 1600 s, and the time derivative of the QPO frequency over timescales of 32 to 160 s. We found that: (i) Both the QPO-frequency spread and the QPO time derivative decrease by a factor ~ 3 as the QPO frequency increases. (ii) The average value of the QPO time derivative decreases by a factor of ~ 2 as the timescale over which the derivative is measured increases from less than 64 s to 160 s. (iii) The relation between the absolute value of the QPO time derivative and the QPO frequency is consistent with being the same both for the positive and negative QPO-frequency derivative. We show that, if either the lower or the upper kHz QPO reflects the Keplerian frequency at the inner edge of the accretion disc, these results support a scenario in which the inner part of the accretion disc is truncated at a radius that is set by the combined effect of viscosity and radiation drag.

description: We investigated the reset time of superconducting nanowire avalanche photodetectors (SNAPs) based on 30 nm wide nanowires. We studied the dependence of the reset time of SNAPs on the device inductance and discovered that SNAPs can provide a speed-up relative to SNSPDs with the same area, but with some limitations: (1) reducing the series inductance of SNAPs (necessary for the avalanche formation) could result in the detectors operating in an unstable regime; (2) a trade-off exists between maximizing the bias current margin and minimizing the reset time of SNAPs; and (3) reducing the reset time of SNAPs below ~ 1 ns resulted in afterpulsing.

description: Attraverso un esercizio di pensiero interculturale, come tentativo di superare ogni forma di monologo e di chiusura identitaria per ripensare le cosiddette “scienze dell'uomo” – dall'antropologia alla pedagogia, dalla psicologia alla sociologia, dall'etnologia alla storia delle religioni – questo articolo cerca di proporre alcune possibili analisi relative all’“estetico”. Questo ambito appare come uno dei caratteri antropologici costitutivi del presente, del mondo attuale, inteso come un complesso laboratorio nel quale forme di vita ed esperienze estetiche appaiono e scompaiono a velocità inedite. Il confronto con linguaggi dell'arte in cui si raccolgono voci differenti diviene un'occasione per elaborare un sapere antropologico e filosofico interculturale: in particolare, il teatro-danza giapponese che ha preso il nome di butō si presenta come un campo d'indagine privilegiato per osservare come si possano ibridare sguardi, culture e dimensioni del corpo plurali.

description: Gli effetti politici, sociali e culturali del crollo del muro di Berlino hanno fortemente influenzato l’arena pubblica odierna. Il neoliberalismo, la conseguente crisi economica del 2008 e la contemporanea rivoluzione digitale hanno visto lo Stato soccombere all’individualismo e a una generazione di politici altamente ‘performativi’ per i quali la distinzione tra sfera pubblica e privata viene meno. Il carattere eminentemente razionale della politica è venuto così a perdersi in una comunicazione spettacolare e ipermediatica. L’ ‘arte del governo’ è diventa quella della ‘messa in scena’. L’uomo di stato si è trasformato in performer. Nella dialettica tra sacro e profano, il vecchio deve morire per resuscitare nel suo opposto, come il pubblico chiede. L’articolo discute il ruolo giocato dalla cultura popolare (Carnevale, Quaresima, Pasqua) e dalla comicità nello show (e ‘commedificazione’) della politica italiana degli ultimi 25 anni. Mette a fuoco la vittoria di Berlusconi, ottenuta grazie alla personificazione della nuova cultura dell’individualismo popolare, fino ad arrivare a Renzi, re dei social media, destinato a fallire a meno che non si dimostri capace di trasformare il teatrino della politica in azione politica.

description: The dynamical nucleus-nucleus potentials for some fusion reactions are investigated by using the improved quantum molecular dynamics (ImQMD) model with different sets of parameters in which the corresponding incompressibility coefficient of nuclear matter is different. Two new sets of parameters SKP* and IQ3 for the ImQMD model are proposed with the incompressibility coefficient of 195 and 225 MeV, respectively. The measured fusion excitation function for 16O+208Pb and the charge distribution of fragments for Ca+Ca and Au+Au in multi-fragmentation process can be reasonably well reproduced. Simultaneously, the influence of the nuclear matter incompressibility and the range of nucleon-nucleon interaction on the nucleus-nucleus dynamic potential is investigated.

description: Purpose: Preterm infants <29 weeks of gestation are at risk for severe intraventricular hemorrhage (IVH). Lower gestational age, birth weight, severe illness, as indexed by higher Score for Neonatal Acute Physiology - Perinatal Extension II (SNAPPE-II) are associated with severe IVH. The role of coagulation abnormalities on the first day after birth in severe IVH remains controversial. The present study investigated factors that predict the risk of severe IVH, including SNAPPE-II at 12 h and coagulation parameters on the first day after birth. Materials and methods: A retrospective chart review of infants < 29 weeks of gestation from January 2008 to December 2013 was performed. Prenatal and postnatal characteristics, SNAPPE-II at 12 h, coagulation parameters [prothrombin time (PT), INR, partial thromboplastin time (aPTT), thrombin time (TT), and fibrinogen] on the first day and cranial ultrasound examination records were collected. The association between clinical and laboratory variables and severe IVH was determined. A joint predictive model for the risk of severe IVH (grades 3 and 4) versus no-mild IVH (grades 0, 1, and 2) was developed using multiple regression analysis. Results: Preterm infants of gestational age < 29 weeks were included (n = 101). Fifteen (15%) infants had severe IVH. Lower gestational age (p = .006), birth weight (p = .008), African American race (p = .031) and higher SNAPPE-II at 12 h (p = .001) were associated with severe IVH. Infants with severe IVH had longer PT (p = .004), higher INR (p = .004) and lower platelet count (p = .034) than those with no-mild IVH. Stepwise logistic regression showed that only SNAPPE-II at 12 h was an independent predictor of severe IVH. For each unit increase in SNAPPE-II, the log odds of severe IVH increased by 0.045 (95% CI: [0.017, 0.073]; p = .002). A threshold of 55 on the SNAPPE-II yielded a sensitivity of 60% (9/15), a specificity of 91% (78/86), a positive predictive value (PPV) of 53% (9/17) and a negative predictive value (NPV) of 93% (78/84). All other demographic and clinical variables and coagulation abnormalities had an insignificant coefficient (p > .05) when included in a bivariate logistic model with SNAPPE-II. Conclusion: SNAPPE-II at 12 h after birth is an independent predictor of severe IVH in preterm infants with gestational age < 29 weeks.

description: La compagnia FFF (The Friendly Face of Fascism) guidata dal regista catalano Roger Bernat si inserisce all'interno del panorama del teatro partecipato contemporaneo. Attiva nello scenario teatrale di Barcellona a partire dal 2008, la formazione artistica si configura come vero emblema del teatro interattivo catalano e permette così di riconsiderare, per forma e significati, le sfumature proprie del paradigma partecipativo. La scomparsa di attori professionisti negli spettacoli di FFF provoca il delinearsi di una nuova figura, quella dello spett-attore: a lui il compito di determinare le trame della messa in scena in quello che diviene un teatro d'efervescencia, con caratteristiche che attengono a un contesto sociale e politico, oltre che scenico. Tale contributo, senza pretesa di esaustività, cercherà di delineare il ruolo e la posizione assunte dallo spett-attore nel contesto scenico. Elementi che consentiranno di conferire un volto altro al paradigma partecipativo.

Le processioni carnevalesche ne sono un esempio significativo. Le maschere sono la parte essenziale del costume carnevalesco. Vengono indossate con lo scopo di accrescere le forze creative della vita e allo stesso tempo per scacciare le forze negative. La maschera è il simbolo di ogni metamorfosi: in questo senso, i riti di Carnevale e della Commedia dell’Arte rivelano personaggi e azioni simili, che possono essere ricondotti alla struttura di un medesimo dramma.

description: The paper is devoted to the proof of the uniqueness theorem for solution of the equation for the non-local ionization source in a glow discharge and a hollow cathode in general 3D geometry. The theorem is applied to wide class of electric field configurations, and to the walls of discharge volume, which have a property of incomplete absorption of the electrons. Cathode is regarded as interior singular source, which is placed arbitrarily close to the wall. The existence of solution is considered also. During the proof of the theorem many of useful structure formulae are obtained. Elements of the proof structure, which have arisen, are found to have physical sense. It makes clear physical construction of non-local electron avalanche, which builds a source of ionization in glow discharge at low pressures. Last has decisive significance to understand the hollow cathode discharge configuration and the hollow cathode effect.

description: Already facing over $400 billion in reconstruction costs in 2023 and an ongoing war, Ukraine confronts seemingly insurmountable challenges for EU accession. Even without compensating for war damages, the financial burden of aligning with the EU is significant. Our study highlights synergies between the EU accession process and reconstruction: with consistent guidance, costs for rebuilding and economic modernisation can go hand in hand. The EU accession path can serve as a critical catalyst, enabling Ukraine’s economy to emulate the convergence success of EU-CEE countries with a focus on sustainable, green and digital development. Breaking the cycle of weak FDI attraction and addressing demographic challenges will be crucial.
title: Entwicklung strukturierter Oberflächen zur Verbesserung der Osseointegration von PEEK
Creators: name: Martin, Anne
Publisher: name: UNSPECIFIED
Year: 2022

description: Für Implantate stehen verschiedenste Werkstoffe zur Verfügung. Häufig im Einsatz, auch aufgrund ihrer sehr guten osseointegrativen Eigenschaften, sind Titanimplantate. Eine Alternative ist aufgrund seiner radiologischen Transparenz und der knochenähnlichen mechanischen Eigenschaften PEEK (Polyetherehterketon). Für ein schnelles Einheilverhalten sowie die Langzeitstabilität der Implantate ist eine dauerhaft stabile Anbindung (Osseointegration) an den Knochen essenziell, welche massiv von den Oberflächeneigenschaften bestimmt wird. So ist neben der Superhydrophilizität eine Kombination aus Nanostruktur und moderater Mikrostruktur von Titanoberflächen sehr förderlich. PEEK hingegen vermindert aufgrund seines inerten Charakters die Ausbildung einer direkten Knochen-Implantat Anbindung. Um die Vorteile beider Werkstoffe zu verbinden und somit das Einheilverhalten und die Langzeitbeständigkeit zu optimieren, wurde bereits ein Verfahren entwickelt, welches mittels physikalischer Gasphasenabscheidung Titan auf PEEK appliziert. In der hier vorliegenden Arbeit wurden verschiedene Methoden untersucht und bewertet, die es ermöglichen, zusätzlich eine moderate Rauheit in das Titan-PEEK-Schichtsystem einzubringen. Es wurden hierfür zwei Methoden erprobt. Die Stempelmethode arbeitet über verschieden sandgestrahlte Stempel, welche bei Raumtemperatur und bei 240 °C auf die Oberflächen von Spritzguss-PEEK Proben gepresst werden. Vergleichend dazu wurden auf unterschiedlich sandgestrahlten Bauplattformen PEEK Proben additiv gedruckt. Für das Stempeln bei Raumtemperatur konnte zwar eine gewünscht moderat raue Oberfläche gemessen werden. Jedoch wurden Teile der Oberfläche nicht strukturiert. Bei der Strukturierung bei 240 °C wurde zwar eine homogene Verteilung der Oberflächenstruktur erreicht, jedoch konnte nicht die gewünschte Größenordnung der Rauheit erzielt werden. Die Substratrauheit und der Einbau einer TiO2-Schicht in die Titanbeschichtung sowie das Weglassen der in situ Kühlung beim Beschichten zeigen positive Auswirkungen auf die kohäsiven und adhäsiven Schichteigenschaften. In Auslagerungsversuchen konnte beobachtet werden, dass sich die vermehrt oberflächennahe Ausbildung amorpher Anteile nachteilig auf die Schichtbeständigkeit auswirken kann. Für die gedruckten PEEK Oberflächen konnte eine homogene Rauheit in der gewünschten Größenordnung erreicht werden. Die erzeugten Schichtsysteme weisen neben sehr guten tribologischen Schichteigenschaften auch eine mittels Nanorauheit erzeugte Superhydrophilizität für 3 Monate auf.

description: The National Marine Fisheries Service (NMFS) is required under the Marine Mammal Protection Act (MMPA) to estimate the annual human-caused mortality and serious injury of marine mammal stocks by source. Revisions to NMFS’ guidelines and methods for distinguishing serious from non-serious injuries pursuant to the MMPA were implemented in 2013. Data from documented interactions between humans and Alaska pinnipeds and cetaceans under the jurisdiction of the NMFS were compiled for the 5-year period from 2009 through 2013. Details regarding each human-marine mammal interaction were reviewed for evidence of human-caused injury or mortality, and criteria were applied in order to assign injuries to categories and determine the severity (serious or non-serious). A total of 603 unique interactions with potential evidence of human-caused injury and mortality were closely reviewed and are summarized in this report. Injury determination details regarding the injury source, type, and severity are presented, along with the injury category and criteria supporting the determination. Mortality and injury values were assigned (0, 1, or prorated) to each event for comparison with the calculated Potential Biological Removal levels for each stock.

description: We derive the sub-subleading two-pion exchange contributions to the three-nucleon force which appear at next-to-next-to-next-to-next-to-leading order in chiral effective field theory. In order to determine the low-energy constants, a complete analysis of pion-nucleon scattering at the subleading-loop order in the heavy-baryon expansion is carried out utilizing the power counting scheme employed in the derivation of the nuclear forces. We discuss the convergence of the chiral expansion for this particular three-nucleon force topology and give the values of the low-energy constants which provide the most realistic description of the three-nucleon force when the chiral expansion is truncated at next-to-next-to-leading order.

description: In this paper three things are done. (i) We investigate the analogues of Cerenkov radiation for the decay of a superluminal neutrino and calculate the Cerenkov angles for the emission of a photon through a W loop, and for a collinear electron-positron pair, assuming the tachyonic dispersion relation for the superluminal neutrino. The decay rate of a freely propagating neutrino is found to depend on the shape of the assumed dispersion relation, and is found to decrease with decreasing tachyonic mass of the neutrino. (ii) We discuss a few properties of the tachyonic Dirac equation (symmetries and plane-wave solutions), which may be relevant for the description of superluminal neutrinos seen by the OPERA experiment, and discuss the calculation of the tachyonic propagator. (iii) In the absence of a commonly accepted tachyonic field theory, and in view of an apparent "running" of the observed neutrino mass with the energy, we write down a model Lagrangian, which describes a Yukawa-type interaction of a neutrino coupling to a scalar background field via a scalar-minus-pseudoscalar interaction. This constitutes an extension of the standard model. If the interaction is strong, then it leads to a substantial renormalization-group "running" of the neutrino mass and could potentially explain the experimental observations.

description: We consider the non-relativistic superconformal U(N) X U(N) Chern-Simons theory with level (k,-k) possessing fourteen supersymmetries. We obtain an exact four-point scattering amplitude of the theory to all orders in 1/N and 1/k and prove that the scattering amplitude becomes trivial when k=1 and 2. We confirm this amplitude to one-loop order by using an explicit field theoretic computation and show that the beta function for the contact interaction vanishes to the one-loop order, which is consistent with the quantum conformal invariance of the underlying theory.

description: We discuss the role of higher order couplings in conjunction with kaon condensation using recent versions of relativistic mean field models.We focus on an interaction (G2) in which all the parameters are obtained by fitting the finite nuclear data and successfully applied to reproduce a variety of nuclear properties. Our results show that the higher order couplings play a significant role at higher densities where kaons dominate the behavior of the equation of state. We compare our results with other interactions (NLl, NL3, G1, and FSUGold) and show that the new couplings bring down the mass of a neutron star (NS), which is further reduced in the presence of kaons to yield results consistent with the present observational constraints. We show that the composition of the NS varies with the parameter sets.

The interpretation of these symmetries as differential-difference equations leads to corresponding hierarchies of such equations for which conservation laws and Lax pairs are constructed. Finally, using the continuous symmetry reduction approach, an integrable, multidimensionally consistent system of partial differential equations is derived in relation with the lattice modified Boussinesq system.

Indirect Trajectory Optimization Using Automatic Differentiation

description: Current indirect optimal control problem (IOCP) solvers, like beluga or PINs, use symbolic math to derive the necessary conditions to solve the IOCP. This limits the capability of IOCP solvers by only admitting symbolically representable functions. The purpose of this thesis is to present a framework that extends those solvers to derive the necessary conditions of an IOCP with fully numeric methods. With fully numeric methods, additional types of functions, including conditional logic functions and look-up tables can now be easily used in the IOCP solver.
 This aim was achieved by implementing algorithmic differentiation (AD) as a method to derive the IOCP necessary conditions into a new solver called Giuseppe. The Brachistochrone problem was derived analytically and compared Giuseppe to validate the automatic derivation of necessary conditions. Two additional problems are compared and extended using this new solver. The first problem, the maximum cross-range problem, demonstrates a trajectory can be optimized indirectly while utilizing a conditional density function that switches as a function of height according to the 1976 U.S. atmosphere model. The second problem, the minimum time to climb problem, demonstrates a trajectory can be optimized indirectly while utilizing 6 interpolated look up tables for lift, drag, thrust, and atmospheric conditions. The AD method yields the exact same precision as the symbolic methods, rather than introducing numeric error as finite difference derivatives would with the benefit of admitting conditional switching functions and look-up tables.

description: The role of ionic interactions between sodium dodecyl sulfate, SDS, and sapphire surfaces have been studied using specular neutron reflection to determine the structure and composition of adsorbed surfactant layers. Increasing the pH of the solution from 3 to 9 reduces the adsorption by reversing the charge of the alumina. This occurs at lower pH for the R-plane (1 -1 0 2) than the C-plane (0 0 0 1), corresponding to the different points of zero charge. The largest surface excess is about 6.5 micromol m-2, the thickness of the adsorbed layer is about 24 Angstrom and it contains roughly 20% water. The hydrocarbon tails of the surfactant molecules clearly interpenetrate rather than form an ordered bilayer. The structure is similar in either pure water or in 0.1 M NaCl when the surfactant is at the respective critical micelle concentration. Different structures were seen with lithium and cesium dodecyl sulfate. The CsDS forms dense layers with little or no hydration and a surface excess of about 10.5 micromol m-2. The metal cation strongly influences the hydration of the adsorbed surfactant. An overall picture of 'flattened micelles' for the structure of the adsorbed layer is observed

description: The models currently used to examine the behavior transportation systems are usually modespecific. That is, they focus on a single mode (i.e. railways, highways, or waterways). The lack of integration limits the usefulness of models to analyze the intermodal movement of freight. This project developed a GIS-based model of the three primary surface modes as well as intermodal connections. The resulting Integrated Freight Network Model (IFNM) accommodates highly detailed about shipping costs, transfer costs, traffic volumes (including non-freight auto traffic), and network interconnectivity properties. As a proof of concept, the research team conducted an exploratory analysis that asked what the potential impact would be to Kentucky highways if approximately half of the freight currently transported by barges on the Ohio River were shifted onto trucks. Coal-haul roads in the northeastern and western part of Kentucky would be particularly hard hit by a broad scale modal shift. The IFNM highlighted that roads emanating from the Western Coalfields would experience explosive growth in freight transport, with the proportion of trucks relative to overall traffic significantly increasing. Applying the IFNM to a range of freight-related transportation questions could greatly enhance system efficiencies and positively impact local economies and environments.

description: Financial literacy not only influences the financial decision and quality of life of an individual but it significantly influences the economic development of a nation. But the financial literacy level is remarkably low worldwide especially in developing countries like India. It leads to the poverty, poor access to finance and wrong decision making in investment. The researcher identifying five significant factors influencing financial literacy on the basis of a literature review. For obtaining the results, structural equation modeling (SEM) has been utilized to examine the 334 individual data, collected by the researchers with aiming to improve financial literacy. The result of the study shows that financial education, financial behavior, financial inclusion are significantly influenced the financial literacy however financial attitude has no significant effect. The outcome of the study will help the government and nongovernment institutions to policy and strategy formulation for further improvement of the level of financial literacy.

description: The crystal structure and magnetic ordering pattern of PdAs2O6 were investigated by neutron powder diffraction. While the magnetic structure of PdAs2O6 is identical to the one of its isostructural 3d-homologue NiAs2O6, its Néel temperature (140 K) is much higher than the one of NiAs2O6 (30 K). This is surprising in view of the long distance and indirect exchange path between the magnetic Pd$^{2+}$ ions. Density functional calculations yield insight into the electronic structure and the geometry of the exchange-bond network of both PdAs2O6 and NiAs2O6, and provide a semi-quantitative explanation of the large amplitude difference between their primary exchange interaction parameters.

description: We present results of micron - resolution measurements of the ground motions in large particle accelerators over the range of spatial scales L from several meters to tens of km and time intervals T from minutes to several years and show that in addition to systematic changes due to tides or slow drifts, there is a stochastic component which has a "random - walk" character both in time and in space. The measured mean square of the relative displacement of ground elements scales as dY**2 \approx ATL over broad range of the intervals, and the site dependent constant A is of the order of 10**-5\pm1 mu m**2/(s-m).

description: We demonstrate controlled pumping of Cooper pairs down to the level of a single pair per cycle, using an rf-driven Cooper-pair sluice. We also investigate the breakdown of the adiabatic dynamics in two different ways. By transferring many Cooper pairs at a time, we observe a crossover between pure Cooper-pair and mixed Cooper-pair-quasiparticle transport. By tuning the Josephson coupling that governs Cooper-pair tunneling, we characterize Landau-Zener transitions in our device. Our data are quantitatively accounted for by a simple model including decoherence effects.

Supplemenatry_Information.docx from Seed size variation impacts local adaptation and life-history strategies in a perennial grass

description: Seed mass is an ecologically important trait that often differs considerably among ecotypes. Yet, because few studies examine the impacts of seed mass on adult life-history traits, its role in local adaptation is unclear. In this study, using accessions of Panicum hallii that spanned the two major ecotypes, we examined whether covariation between seed mass, seedling and reproductive traits impacts ecotypic divergence and local adaptation. The perennial grass P. hallii has two distinct ecotypes—a large-seeded upland ecotype adapted to xeric environments and a small-seeded lowland ecotype adapted to mesic environments. In the greenhouse, seed mass varied greatly across P. hallii genotypes in a manner consistent with ecotypic divergence. Seed mass covaried significantly with several seedling and reproductive traits. At field sites representing the habitats of the two ecotypes, seed mass had different impacts on seedling and adult recruitment: selection favoured large seeds in upland habitat and small seeds in lowland habitat, which was consistent with local adaptation. By demonstrating the central role of seed mass in ecotypic differences in P. hallii and its importance to seedling and adult recruitment under field conditions, these studies show that early life-history traits can promote local adaptation and potentially explain ecotype formation.
title: Einfluss der Mikrostruktur auf das Fließverhalten von metallischen Werkstoffen in Mikro- und Nanokavitäten -Nanoimprinting-

description: Im Rahmen dieser Arbeit wird das neuentwickelte metallische Nanoimprinting untersucht, welches verspricht robuste Oberflächenstrukturen durch gezielte plastische Verformung herzustellen. Hierzu wurden zylindrische Eindringkörper aus Diamant in Einzelkontaktversuchen verwendet, welche mit Ringkavitäten an den Kontaktflächen versehen waren. Dabei hängen die herstellbaren Strukturen nicht nur von den Werkzeuggeometrien, sondern maßgeblich von den Mikrostrukturen und mechanischen Eigenschaften der Substrate ab. Um ein weites Feld an Mikrostrukturen und Werkzeuggeometrien abzubilden, wurde ein Multiskalenansatz gewählt, in welchem die Werkzeugdurchmesser und Mikrostrukturgrößen in einem weiten Bereich variiert wurden. So wurde der Werkzeugdurchmesser von 1 bis 50 µm und die Kavitätenbreite zwischen 20 nm und 2,76 µm verändert. Als Substrate wurden hauptsächlich Kupferlegierungen (CuSn5, CuZn5 und CuZn30) in unterschiedlichen Zuständen verwendet. Durch High Pressure Torsion (HPT) wurden minimale Korngrößen von 60 nm und durch Rekristallisation maximale Korngrößen von 277 µm erreicht. Zusätzlich wurden auch kaltverformte Proben als Substrat verwendet, welche hohe (Großwinkel-)Korngrößen bei einer hohen Versetzungsdichte aufwiesen. Neben diesen Zuständen wurde auch galvanisch abgeschiedenes nanokristallines Nickel (durchschnittliche Korngrößen von etwa 100 nm) in unterschiedlichen Schichtdicken und auch als Vollmaterial untersucht. Durch diese Variationen werden unterschiedliche Fließprozesse in die Werkzeugstrukturen erwartet, welche mithilfe von TEM-Untersuchungen charakterisiert wurden. Experimentelle Ergebnisse zeigen, dass sowohl das Kaltverfestigungsverhalten als auch die Subkorn- bzw. Korngröße die Extrusionseigenschaften beim Nanoimprinting maßgeblich beeinflussen und ein nahezu ideales plastisches Verhalten (keine Kaltverfestigung) zu den höchsten Extrusionen führt. Für Werkstoffe mit einer ausgeprägten Kaltverfestigung wurden für alle Kavitätenbreiten niedrige Extrusionshöhen gemessen. Diese Arbeit demonstriert das Potential eines einfachen Prägeverfahrens zur Erzeugung von Oberflächenmerkmalen auf metallischen Werkstoffen mit einer Breite < 300 nm und einem Aspektverhältnis größer eins. Abschließend konnte mithilfe eines laserstrukturierten Hartmetallwerkzeugs demonstriert werden, dass mithilfe des metallischen Nanoimprintings auch große und somit technisch relevante, Oberflächen strukturiert werden können.

description: The nonlinear dynamics of a Bose-Einstein condensate (BEC) of dipolar excitons trapped in an external confining potential in coupled quantum wells is analysed. It is demonstrated that under typical experimental conditions the dipolar excitons BEC can be described by a generalized Gross-Pitaevskii equation with the local interaction between the excitons, which depends on the exciton distribution function. It is shown that, if the system is pumped at sufficiently high frequencies, a steady turbulent state can be formed.

description: During 2013, the Kentucky Transportation Center identified 117 potential performance metrics for the ten databases in the Kentucky Traffic Records System. This report summarizes the findings of three main tasks completed in 2014: (1) assessment of the utility of each metric and/or the availability of data; (2) collection of data on the metrics deemed useful with available data; and (3) assessment the possibility of incorporating a number of the Model Minimum Uniform Crash Criteria (MMUCC) elements into the CRASH database. Interviews with liaisons for each database reduced the number of metrics from 117 to 51. The reason for rejecting the metric as useless is provided in two tables. Data on the useful and data available metrics is reported in one or more tables for each database. The review of the CRASH database for compliance with MMUCC found that 470 of 682 elements are currently MMUCC compliant. A total of 137 elements could be added to the CRASH database, which would render it 89% MMUCC compliant. A list of tentative conclusions is provided.
