description: We consider breaking of supersymmetry in intersecting D-brane configurations by slight deviation of the angles from their supersymmetric values. We compute the masses generated by radiative corrections for the adjoint scalars on the brane world-volumes. In the open string channel, the string two-point function receives contributions only from the infrared and the ultraviolet limits. The latter is due to tree-level closed string uncanceled NS-NS tadpoles, which we explicitly reproduce from the effective Born-Infeld action. On the other hand, the infrared region reproduces the one-loop mediation of supersymmetry breaking in the effective gauge theory, via messengers and their Kaluza-Klein excitations. In the toroidal set-up considered here, it receives contributions only from broken N=4 and N=2 supersymmetric configurations, and thus always leads at leading order to a tachyonic direction, in agreement with effective field theory expectations.

description: The structures of the parent compounds of phosphanyl- and arsanylboranes, H2BPH2 and H2BAsH2, were calculated by DFT-B3LYP methods. Such compounds have not previously been obtained preparatively. By applying the concept of Lewis acid/base stabilisation, [(CO)5W(H2EBH2NMe3)] (E=P (3), As (4)) derivatives have been synthesised by the metathesis reactions between Li[(CO)5WEH2] and ClH2BNMe3 (E=P, As). Comprehensive thermodynamic studies on these systems verify the high stability of the Lewis acid/base stabilised complexes. Unexpected based on the thermodynamic calculations, UV radiation of the phosphanylborane 3 leads to the dinuclear phosphanido-bridged complex [(CO)8W2(-PHBH2NMe3)2] (5) by H2 and CO elimination.
Incremental response of granular materials: DEM results

description: We systematically investigate the incremental response of various equilibrium states of dense 2D model granular materials, along the biaxial compression path (σ11 < σ22, σ12 = 0). Stress increments are applied in arbitrary directions in 3- dimensional stress space (σ11, σ22, σ12). In states with stable contact networks we compute the stiffness matrix and the elastic moduli, and separate elastic and irreversible strains in the range in which the latter are homogeneous functions of degree one of stress increments. Without principal stress axis rotation, the response abides by elastoplasticity with a Mohr-Coulomb criterion and a non-associated flow rule. However a nonelastic shear strain is also observed for increments of σ12, and shear and in-plane responses couple. This behavior correlates to the distribution of friction mobilization and sliding at contacts.

description: Transport processes across membranes play central roles in any biological system. They are essential for homeostasis, cell nutrition, and signaling. Fluxes across membranes are governed by fundamental thermodynamic rules and are influenced by electrical potentials and concentration gradients. Transmembrane transport processes have been largely studied on single membranes. However, several important cellular or subcellular structures consist of two closely spaced membranes that form a membrane sandwich. Such a dual membrane structure results in remarkable properties for the transport processes that are not present in isolated membranes. At the core of membrane sandwich properties, a small intermembrane volume is responsible for efficient coupling between the transport systems at the two otherwise independent membranes. Here, we present the physicochemical principles of transport coupling at two adjacent membranes and illustrate this concept with three examples. In the supplementary material, we provide animated PowerPoint presentations that visualize the relationships. They could be used for teaching purposes, as has already been completed successfully at the University of Talca.

description: The reaction between the cluster dianion [Fe3(μ3-Y)(CO)9]2− (1) (Y=Se (a), Te (b)) and MesSbBr2 leads to the formation of [Fe3(μ3-Y)(μ3-SbMes)(CO)9] (2a,b) (Mes=2,4,6-Me3C6H2). The molecular structures of both compounds were established by single crystal X-ray diffraction and reveals nido cluster cores containing square pyramidal FeSbFeY units capped by a third Fe carbonyl fragment as an apical vertex. The novel compound [Fe3(μ3,η2:η1-SeSbMes)(μ3-SbMes)(CO)10] (3) was obtained by a similar reaction via slightly modified reaction conditions. This molecule contains a Fe(CO)4 and a Fe2(CO)6 fragment, respectively, which are connected by a μ3-SbMes and a novel μ3,η2:η1-SeSbMes ligand.

description: The gallium chloro complex [GaCl{Fe(CO)2Cp}2] (Cp = η5-C5H5) was reacted with KP(SiMe3)2 under special conditions to yield the complexes [{CpFe(CO)}2{μ-(CO)}[μ-Ga{CpFe(CO)2}]] (1) and [{CpFe(CO)2}GaP(SiMe3)]4 (2). Furthermore, [[{CpFe(CO)2}ClGa](μ-PPh2)2FeCpCO] (4) was obtained by the reaction of [GaCl{Fe(CO)2Cp}2] with LiPPh2. Complexes 1, 2, and 4 have been characterized spectroscopically and by X-ray structure analysis. Complex 2 represents an ideal Ga4P4-heterocubane, the first Ga-containing example of this structural type with organometallic substituted group 13 elements. In the solid state compound 4 possesses an almost planar GaPFeP four-membered ring, a novel structural motif in mixed group 13/15 chemistry.

In this paper, we present an updated list of the occultations of astrometric radio sources by planets expected in the nearest years. Such events, like the solar eclipses, generally speaking, can be only observed in a limited region. The map of the shadow path is provided for the events occurred in regions with several VLBI stations and hence the most interesting for radio astronomy experiments.

description: Building on existing techniques for satellite remote sensing of fires, this paper takes advantage of the day-night band (DNB) aboard the Visible Infrared Imaging Radiometer Suite (VIIRS) to develop the Firelight Detection Algorithm (FILDA), which characterizes fire pixels based on both visible-light and infrared (IR) signatures at night. By adjusting fire pixel selection criteria to include visible-light signatures, FILDA allows for significantly improved detection of pixels with smaller and/or cooler subpixel hotspots than the operational Interface Data Processing System (IDPS) algorithm. VIIRS scenes with near-coincident Advanced Spaceborne Thermal Emission and Reflection (ASTER) overpasses are examined after applying the operational VIIRS fire product algorithm and including a modified “candidate fire pixel selection” approach from FILDA that lowers the 4-μm brightness temperature (BT) threshold but includes a minimum DNB radiance. FILDA is shown to be effective in detecting gas flares and characterizing fire lines during large forest fires (such as the Rim Fire in California and High Park fire in Colorado). Compared with the operational VIIRS fire algorithm for the study period, FILDA shows a large increase (up to 90%) in the number of detected fire pixels that can be verified with the finer resolution ASTER data (90 m). Part (30%) of this increase is likely due to a combined use of DNB and lower 4-μm BT thresholds for fire detection in FILDA. Although further studies are needed, quantitative use of the DNB to improve fire detection could lead to reduced response times to wildfires and better estimate of fire characteristics (smoldering and flaming) at night.
Adhesive Bonding of an Aluminum Alloy with and without an Oxide Layer in Atmospheres with Different Oxygen Contents

subject: Dewey Decimal Classification::600 | Technik

description: Aluminum surfaces in a normal atmosphere are always coated with a native oxide layer. To prevent a new layer from forming after this oxide layer has been removed, an environment without oxygen must be created. This work uses a new method of doping an inert gas atmosphere with highly reactive silane to ensure technical freedom from oxygen. The influence of the surrounding atmosphere and the influence of the oxide layer on the tensile strength of an aluminum-aluminum joint are investigated. For this purpose, 2-component adhesives are used whose curing mechanisms are fundamentally not based on the reaction with the surrounding atmosphere. The tests are carried out in normal, pure argon, and an oxygen-free argon/silane atmosphere. The experiments show that the surrounding atmosphere influences the strength of the bonded joint. Compared to the oxidized surfaces, the joints of the deoxidized surfaces show a higher tensile strength under constant ambient conditions.

description: This paper examines in-depth processes of librarian professional identity negotiations impacting practitioners’ perception of, affiliation with, and behaviour within the profession. It outlines three key themes which moderate librarian professional identity and introduces the Relational States of Librarian Professional Identity, outlining variations of individual affiliation with the profession. This paper also offers a theoretical framework of identity negotiations with theoretical propositions relating to librarian professional identity development. Forty semi-structed interviews were conducted with practicing public librarians throughout Aotearoa New Zealand. Interviews were analysed with an inductive approach. NVivo was used to code and query interview data. Findings demonstrate identity negotiations as grounded in perceptions of profession through meaning ascribed to the profession and its manifestations (professional associations, etc.), respectively; and perceptions of practice as related to organisational/institutional contexts. Six theoretical propositions are offered detailing the relationship of the three themes moderating librarian professional identity and the Relational States of Librarian Professional Identity to this identity and its negotiations.

description: A supermassive black hole in the nucleus of an elliptical galaxy at the centre of a cool-core group or cluster of galaxies is immersed in hot gas. Bondi accretion should occur at a rate determined by the properties of the gas at the Bondi radius and the mass of the black hole. X-ray observations of massive nearby elliptical galaxies, including M87 in the Virgo cluster, indicate a Bondi accretion rate Mdot which roughly matches the total kinetic power of the jets, suggesting that there is a tight coupling between the jet power and the mass accretion rate. While the Bondi model considers non-rotating gas, it is likely that the external gas has some angular momentum, which previous studies have shown could decrease the accretion rate drastically. We investigate here the possibility that viscosity acts at all radii to transport angular momentum outward so that the accretion inflow proceeds rapidly and steadily. The situation corresponds to a giant Advection Dominated Accretion Flow (ADAF) which extends from beyond the Bondi radius down to the black hole. We find solutions of the ADAF equations in which the gas accretes at just a factor of a few less than Mdot. These solutions assume that the atmosphere beyond the Bondi radius rotates with a sub-Keplerian velocity and that the viscosity parameter is large, alpha~0.1. The infall time of the ADAF solutions is no more than a few times the free-fall time. Thus the accretion rate at the black hole is closely coupled to the surrounding gas, enabling tight feedback to occur. We show that jet powers of a few per cent of Mdot c^2 are expected if either a fraction of the accretion power is channeled into the jet or the black hole spin energy is tapped by a strong magnetic field pressed against the black hole by the pressure of the accretion flow.(Truncated)

description: Zaleya pentandra L. jaffery is the only species of the genus Zaleya that grows in the Cholistan desert, Pakistan. It is a Xero-halophyte plant with high phenolic and flavonoid content. The present research was designed to investigate the phytochemical composition, biological activities, and in silico molecular docking of the ethanolic extract of Z. pentandra. The phytochemical evaluation was done through preliminary phytochemical testing, estimation of total bioactive content, and gas chromatography–mass spectrometry (GC–MS) analysis for the identification of volatile compounds. For the evaluation of biological activities, antioxidants, and enzyme inhibition (α-glucosidase, cholinesterase, and tyrosinase), antibacterial and antiviral assays were performed. GC–MS analysis revealed the presence of 29 tentative volatile compounds. The ethanolic extract of Z. pentandra contains high phenolic content (119.6 ± 0.12 mg GAE/g extract) and flavonoid content (45.5 ± 0.19 mg QE/g extract), which correlates with the strong DPPH, FRAP, and enzyme inhibition results. The ethanolic extract of Z. pentandra also showed dose-dependent antibacterial activity. Micrococcus luteus and Pseudomonas aeruginosa were found to be most susceptible, with 16 mm and 17 mm zone of inhibitions at a maximum dose of 20 mg/mL. Antiviral results showed that the ethanol extract has excellent activity against H9, IBV, and NDV viral strains. Additionally, in silico molecular docking was performed in order to determine the interaction and binding affinity between the enzymes and compounds identified by GC–MS. α-glucosidase, cholinesterase, and tyrosinase showed the highest binding affinity toward 1,2-benzenedicarboxylic acid, 2-hydroxy-n-(2-phenylethyl) benzamide, γ-sitosterol, and lactose. These findings can serve as a benchmark for anti-diabetic-, neuro-, and skin-protective uses of this plant and can be used for the isolation of pure bioactive compounds in the future.

description: Protein complexes of the mitochondrial respiratory chain assemble into respiratory supercomplexes. Here we present the high-resolution electron cryo-microscopy structure of the Arabidopsis respiratory supercomplex consisting of complex I and a complex III dimer, with a total of 68 protein subunits and numerous bound cofactors. A complex I-ferredoxin, subunit B14.7 and P9, a newly defined subunit of plant complex I, mediate supercomplex formation. The component complexes stabilize one another, enabling new detailed insights into their structure. We describe (1) an interrupted aqueous passage for proton translocation in the membrane arm of complex I; (2) a new coenzyme A within the carbonic anhydrase module of plant complex I defining a second catalytic centre; and (3) the water structure at the proton exit pathway of complex III2 with a co-purified ubiquinone in the QO site. We propose that the main role of the plant supercomplex is to stabilize its components in the membrane.

description: In this dissertation, we combine the work of A. Aizenbud and D. Gourevitch on Schwartz functions on Nash manifolds, and the work of F. du Cloux on Schwartz inductions, to develop a toolbox of Schwartz analysis. We then use these tools to study the intertwining operators between parabolic inductions, and study the behavior of intertwining distributions on certain open subsets. Finally we use our results to give new proof of results in Bruhat's thesis on irreducibilities of degenerate principal series and minimal principal series.

description: [Cp*GaCl2] (Cp* = 1-C5Me5) reacts with K[Co(CO)4] with elimination of KCp* and KCl to form the novel ionic complexes [K(toluene)2][Ga{Co2(CO)6(-CO)}2] (1) and K[GaCl{Co2(CO)6(-CO)}{Co(CO)4}] (2), where the gallium atoms possess the coordination number four. The reaction of [{Co(CO)4}2GaCl(THF)] with LiCp* leads to the ionic product [Li(THF)][Ga{Co2(CO)6(-CO)}2] (3). The [Ga{Co2(CO)6(-CO)}2]- anions of 1 and 3 represent the first homoleptic spirocyclic coordination mode of gallium. The reaction of GaCl3 with Na2[Fe(CO)4] leads to the ionic compound [Na(OEt2)2][Fe(CO)4(GaCl3)2] (4). Complexes 1, 2, 3 and 4 were characterised by X-ray structure analysis and IR spectroscopy. Additionally, ESI mass spectra of 1 were recorded at different cone voltages, where the molecular ion peak of the anion [Ga{Co2(CO)6(-CO)}2]- as well as the peaks resulting from sequential loss of CO ligands until the formation of the naked [Co4Ga]- cluster are observed. The ionic complexes 1, 2, 3 and 4 form polymeric networks through coordination of their cations. In 2 a three-dimensional polymeric network is formed by coordination of the Co3Ga units and their K counterions, whereas in 1 the K ions are additionally coordinated by toluene molecules to form dimeric macrocyclic motifs by coordination of two of the anionic Co4Ga units. In 3 a zigzag chain is formed by coordination of the Co4Ga units through their Li cations. In the crystal packing of complex 4 the FeGa2 moieties form zigzag chains, coordinating through their Na counterions.
3D numerical MHD modeling of sunspots with radiation transport

description: Sunspot fine structure has been modeled in the past by a combination of idealized magneto-convection simulations and simplified models that prescribe the magnetic field and flow structure to a large degree. Advancement in numerical methods and computing power has enabled recently 3D radiative MHD simulations of entire sunspots with sufficient resolution to address details of umbral dots and penumbral filaments. After a brief review of recent developments we focus on the magneto-convective processes responsible for the complicated magnetic structure of the penumbra and the mechanisms leading to the driving of strong horizontal outflows in the penumbra (Evershed effect). The bulk of energy and mass is transported on scales smaller than the radial extent of the penumbra. Strong horizontal outflows in the sunspot penumbra result from a redistribution of kinetic energy preferring flows along the filaments. This redistribution is facilitated primarily through the Lorentz force, while horizontal pressure gradients play only a minor role. The Evershed flow is strongly magnetized: While we see a strong reduction of the vertical field, the horizontal field component is enhanced within filaments.

description: The reaction of [Cp*Fe({eta}5-P5)] with Cu(I)Cl in solvent mixtures of CH2Cl2/CH3CN leads to the formation of entirely inorganic fullerene-like molecules of the formula [{Cp*Fe({eta}5:{eta}1:{eta}1:{eta}1:{eta}1:{eta}1-P5)}12{CuCl}10{Cu2Cl3}5{Cu(CH3CN)2}5] (1) possessing 90 inorganic core atoms. This compound represents a structural motif similar to that of C60: cyclo-P5 rings of [Cp*Fe({eta}5-P5)] molecules are surrounded by six-membered P4Cu2 rings that result from the coordination of each of the phosphorus lone pairs to CuCl metal centers, which are further coordinated by P atoms of other cyclo-P5 rings. Thus, five- and six-membered rings alternate in a manner comparable to that observed in the fullerene molecules. The so-formed half shells are joined by [Cu2Cl3]– as well as by [Cu(CH3CN)2]+ units. The spherical body has an inside diameter of 1.25 nanometers and an outside diameter of 2.13 nanometers, which is about three times as large as that of C60.

description: Reactions of Cp*GaCl2 and Cp*2GaCl (Cp*=η1-C5Me5), respectively, with different carbonylmetalate anions are compared to yield the transition-metal–gallium complexes [(η5-Cp*Ga)W(CO)5] (1), [Fe2(CO)6{μ-(η5-Cp*Ga)}2{μ-(η3-Cp*Ga)}] (2), [Ga{Mn(CO)5}3] (3), [Cp*2Ga{Mn(CO)5}] (4), [Co2(CO)6{μ-(η5-Cp*Ga)}2Co(CO)3] (5) and [{(η5-Cp)Fe(CO)}2(μ-CO){μ2-(η5-Cp*Ga}] (6). The results show that both starting materials offer an alternative synthetic route to subvalent Cp*Ga(I) compounds via reductive dehalogenation reactions in comparison to the previously used reactions starting from Cp*Ga itself. Starting from Cp*2GaCl, Cp* elimination reactions are observed additionally, a process which dominates much more in the case of Cp*InCl2 as a starting material. In these reactions with [CpFe(CO)2]− and [CpW(CO)3]−, [In{CpFe(CO)2}3] (7) and [In{CpW(CO)3}3] (8), respectively, are obtained in good yield.

description: Metal hydrides have earlier been suggested for utilization in solar cells. With this as a motivation we have prepared thin films of yttrium hydride by reactive magnetron sputter deposition. The resulting films are metallic for low partial pressure of hydrogen during the deposition, and black or yellow-transparent for higher partial pressure of hydrogen. Both metallic and semiconducting transparent YHx films have been prepared directly in-situ without the need of capping layers and post-deposition hydrogenation. Optically the films are similar to what is found for YHx films prepared by other techniques, but the crystal structure of the transparent films differ from the well-known YH3 phase, as they have an fcc lattice instead of hcp.

description: An analysis of relations between the tunneling rate and the unified first law of thermodynamics at the trapping horizons of two kinds of spherically symmetric dynamical black holes is investigated. The first kind is the Vaidya-Bardeen black hole, the tunneling rate $Γ\sim e^{\triangle S}$ can be obtained naturally from the unified first law at the apparent horizon, which holds the form $dE_{H}=TdS+WdV$. Another is the McVittie solution, the action of the radial null geodesic of the outgoing particles does not always has a pole at the apparent horizon, while the ingoing mode always has one. The solution of the ingoing mode of the radiation can be mathematically reduced to the case in the FRW universe smoothly. However as a black hole, the physical meaning is unclear and even puzzling.

description: The average phase factor of the QCD determinant is evaluated at finite quark chemical potential (μ_q) with the two-flavor version of the Polyakov-loop extended Nambu-Jona-Lasinio (PNJL) model with the scalar-type eight-quark interaction. For μ_q larger than half the pion mass at vacuum m_π, the average phase factor is finite only when the Polyakov loop is larger than 0.5, indicating that lattice QCD is feasible only in the deconfinement phase. A critical endpoint (CEP) lies in the region of the zero average phase factor. The scalar-type eight-quark interaction makes it shorter a relative distance of the CEP to the boundary of the region. For μ_q < m_π/2, the PNJL model with dynamical mesonic fluctuations can reproduce lattice QCD data below the critical temperature.

description: In this work, the influence of two different types of cations on the gel formation and structure of mixed gel networks comprised of semiconductor (namely CdSe/CdS nanorods NR) and Au nanoparticles (NP) as well as on the respective monocomponent gels is investigated. Heteroassemblies built from colloidal building blocks are usually prepared by ligand removal or cross-linking, thus, both the surface chemistry and the destabilising agent play an essential role in the gelation process. Due to the diversity of the composition, morphology, and optical properties of the nanoparticles, a versatile route to fabricate functional heteroassemblies is of great demand. In the present work, the optics, morphology, and gelation mechanism of pure semiconductor and noble metal as well as their mixed nanoparticle gel networks are revealed. The influence of the gelation agents (bivalent and trivalent cations) on the structure-property correlation is elucidated by photoluminescence, X-ray photoelectron spectroscopy, and electron microscopy measurements. The selection of cations drastically influences the nano- and microstructure of the prepared gel network structures driven by the affinity of the cations to the ligands and the nanoparticle surface. This gelation technique provides a new platform to control the formation of porous assemblies based on semiconductor and metal nanoparticles.

description: We present a comparison between Fe K-edge x-ray absorption spectra of carbonmonoxy-myoglobin and its simulation based on density-functional theory determination of the structure and vibrations and spectral simulation with multiple-scattering theory. An excellent comparison is obtained for the main part of the molecular structure without any structural fitting parameters. The geometry of the CO ligand is reliably determined using a synergic approach to data analysis. The methodology underlying this approach is expected to be especially useful in similar situations in which high-resolution data for structure and vibrations are available.

Effects of hearing aid processing on cortical auditory evoked potentials in normal hearing individuals
Creators: name: Meagher, Kelsey Marie
Publisher: name: University of British Columbia
Year: 2017

description: Cortical auditory evoked potentials (CAEPs) are currently being investigated as a tool for validation in hearing aid fittings. There is some conflicting evidence regarding the usefulness of CAEPs in this capacity. CAEPs are influenced by stimulus parameters and hearing aids can change these parameters in an unpredictable manner. The purpose of this study was to investigate the effect of rise time after hearing aid processing on the CAEP of 23 normal hearing participants. Two different duration stimuli (60 ms and 120 ms) were processed by three different hearing aids and the output of each hearing aid was recorded. The stimulus parameters were measured for each condition and the stimuli were presented to each participant through an insert earphone. Two blocks of stimuli were used (1) Raw (varied SNR and intensity) and (2) Equalized/Filtered (equalized SNR and intensity). The electroencephalography (EEG) was recorded and the P1-N1-P2 amplitudes and latencies were measured for each condition. A three-factor ANOVA was conducted to observe the effects of (1) rise time, (2) duration, and (3) SNR. A main effect of rise time was observed on the N1-P2 amplitude. This result indicated that hearing aid processing can increase the rise time enough to elicit a decrease in the N1-P2 amplitude. No effects were observed on amplitudes or latencies of the N1-P2 with the alternative stimulus parameters (SNR and duration). Prior to using CAEPs clinically for validation of hearing aid fittings, normative standards should be established. This ensures that differences in the N1-P2 amplitudes are due specifically to audibility and not to the altered stimulus parameter (i.e., after hearing aid processing). Further research should also be conducted on individuals with hearing loss to see if the effects observed in this study would be present with this population. In addition, comparisons of behavioural and CAEP methods of validation would be helpful in determining the validity and reliability of using these methods clinically.

description: Die vorliegende Arbeit beschäftigt sich mit dem Thema Innovation in der Sozialen Arbeit. Dabei wird herausgearbeitet, was darunter zu verstehen ist und welche Faktoren Innovationsprozesse in Institutionen der Sozialen Arbeit fördern. Weiter befasst sich die Arbeit mit einer für die Soziale Arbeit neuen Methode zur Innovationsentwicklung, nämlich der Design Thinking Methode. Auch hier geht die Autorenschaft der Frage nach förderlichen Bedingungen für die Anwendung der Methode nach. Hintergrund dieser Arbeit bildet der gesellschaftliche Wandel mit den sich verändernden Problemlagen. Diese haben Einfluss auf die Rahmenbedingungen der Sozialen Arbeit und stellen diese vor neue herausfordernde Aufgaben. Eine Möglichkeit für die Soziale Arbeit darauf zu reagieren, ist innovativer zu werden, die Angebote anzupassen und weiterzuentwickeln. Aus Sicht der lebensweltorientierten Sozialen Arbeit und anlehnend an den Berufskodex ist es hierbei wichtig partizipativ mit den Adressat_innen zu arbeiten. Die Design Thinking Methode bietet sich für das partizipative Entwickeln von innovativen Lösungsansätzen an. In der Arbeit werden deshalb vier Expert_innen aus verschiedenen Berufsfeldern mit jeweils unterschiedlichen Bezügen zur Sozialen Arbeit, zu ihren Erfahrungen mit der Design Thinking Methode befragt. Mittels qualitativer Leitfadeninterviews wird der Frage nach förderlichen Bedingungen für die Anwendung der Design Thinking Methode nachgegangen. Die Ergebnisse dieser Arbeit zeigen förderliche Faktoren für innovative Prozesse und die Design Thinking Methode auf, wie zum Beispiel den Einbezug der Adressat_innen, die positive Haltung zur Fehler- und Experimentierkultur und die interdisziplinäre Zusammenarbeit.

description: We theoretically predict the occurrence of multiple hydrodynamical-like shock phenomena in the propagation of ultrashort intense pulses in a suitably engineered photonic crystal fiber. The shocks are due to the Raman effect, which acts as a nonlocal term favoring their generation in the focusing regime. It is shown that the problem is mapped to shock formation in the presence of a slope and a gravity-like potential. The signature of multiple shocks in XFROG signals is unveiled.
