Leuctra tenuis

description: Leuctra tenuis (Pictet). This species is widely distributed across eastern North America (DeWalt et al. 2010) and has been reported from ravine streams in eastern Illinois (DeWalt 2002) and Trout Park near Elgin, in Kane County of northern Illinois (Frison 1935). It has since been extirpated from the latter location (DeWalt et al. 2005). Grubbs (2004) reported this species from southern Indiana near the Ohio River in Harrison County, Indiana. We have recently collected this species from several ravine streams in central Indiana. The range of this species in Indiana is probably broader, but its late summer to autumn emergence has likely precluded a more comprehensive understanding of its statewide distribution.

description: A technique for constructing the nucleon-nucleon transition matrices T in the presence of inelastic channels is given. The present technique avoids the usual potential fit and continues T off the energy shell directly consistent with the two-body scattering data and consistent with the properties of possible two-body bound states. The respective T matrices are determined by a real symmetric matrix function ⟨E1α1|σ|E2α2⟩ of the continuous energy variable E and the discrete eigenchannel label α. The on-shell part of σ is given by the eigenphases; the arbitrariness of T is the off-shell continuation of the phase-shift matrix ⟨Eα1|σ|Eα2⟩ into two dimensions. The present technique of constructing T makes the experimental nucleon-nucleon and meson-nucleon scattering data readily available as input for nuclear theory extended to include baryon resonances.

description: We present nine near-infrared (NIR) spectra of supernova (SN) 2005cf at epochs from -10 d to +42 d with respect to B-band maximum, complementing the existing excellent data sets available for this prototypical Type Ia SN at other wavelengths. The spectra show a time evolution and spectral features characteristic of normal Type Ia SNe, as illustrated by a comparison with SNe 1999ee, 2002bo and 2003du. The broad-band spectral energy distribution (SED) of SN 2005cf is studied in combined ultraviolet (UV), optical and NIR spectra at five epochs between ~ 8 d before and ~ 10 d after maximum light. We also present synthetic spectra of the hydrodynamic explosion model W7, which reproduce the key properties of SN 2005cf not only at UV-optical as previously reported, but also at NIR wavelengths. From the radiative-transfer calculations we infer that fluorescence is the driving mechanism that shapes the SED of SNe Ia. In particular, the NIR part of the spectrum is almost devoid of absorption features, and instead dominated by fluorescent emission of both iron-group material and intermediate-mass elements at pre-maximum epochs, and pure iron-group material after maximum light. A single P-Cygni feature of Mg II at early epochs and a series of relatively unblended Co II lines at late phases allow us to constrain the regions of the ejecta in which the respective elements are abundant.

title: Krebserkennung durch multispektrale Gewebeuntersuchung
Creators: name: Braun, Frank
Publisher: name: Heidelberg University Library
Year: 2019

description: Der Einsatz von optischen Messtechniken im medizinischen Umfeld ist in der Regel auf eine Technologie beschränkt. In der Krebsdiagnostik kommt mehrheitlich die laserinduzierte Fluoreszenzspektroskopie (FL) zum Einsatz. In der vorliegenden Arbeit wird eine kombinatorische Nutzung unterschiedlicher Spektroskopie-Arten für die instrumentelle Realisierung in einer neuartigen, faseroptischen, multispektralen, in-vivo Stichsonde, basierend auf dem Rückstreuprinzip, entwickelt und erprobt. Zum Einsatz kommen die Techniken: Ultraviolett- (UV), visuelle- (VIS), nahinfrarot- (NIR) und Fluoreszenz (FL)-Spektroskopie. Die Kompatibilität der simultan angewandten Ultraschall-Bildgebung oder Magnetresonanztomographie (MRT) wird durch die Werkstoffauswahl eines Nitinol- und Polymerverbundes erreicht.
Die optische Evaluation der Sonde erfolgt in einem Gewebephantom bei verschiedenen Streuer- und Absorberkonzentrationen in-vitro. Hierzu wird eine Dispersion mit Wasser als Lösungsmittel entwickelt. Mit dieser können verschiedene Streu- und Absorptionskoeffizienten des menschlichen oder tierischen Gewebes nachgeahmt und deren Auswirkungen auf die Fluoreszenzemissionsmessung untersucht werden. Dieses künstliche Stoff-System basiert auf den Stoffen: Wasser (Lösungsmittel), Calcilit 4 (Streuer, Calciumcarbonat, Partikelgröße 4 Mikrometer), New Coccine (Absorber, blutähnliches Spektrum) und Nicotinamidadenindinucleotidhydrat (NADH; Fluorophor). Aus diesem Teil der Untersuchungen resultierend, entsteht ein Streukorrektur-Auswertealgorithmus zur quantitativen Messung des Fluorophors (NADH). Der publizierte Algorithmus erreicht eine Genauigkeit (RMSEP) von 0,093 mmol/l innerhalb physiologischer NADH-Konzentrationen. Die praktische Anwendbarkeit erfolgt in einem Tiermodell (NMRI-Mäuse). Bei den Versuchen wird die Stichsonde, die im Rahmen dieser Dissertation entwickelt und publiziert wurde, startend in gesundem Gewebe, konsekutiv durch bösartiges Gewebe geführt und die spektralen Daten aller multimodalen Messbereiche bei ihren jeweiligen Positionen aufgenommen. Die Kombination aller gewonnenen Informationen ermöglicht eine markierungsfreie Klassifikation des jeweiligen Gewebes mithilfe einer virtuellen, photometrischen Hauptkomponentenanalyse (PCA). Durch diese Point-of-Care-Messtechnik kann zwischen malignem und benignem Gewebe aufgrund von Veränderungen biochemischer, physikalisch-morphologischer und kolorimetrischer Werte unterschieden werden. Eine in-vivo-Vorauswahl für die Entnahme von Biopsien ist dadurch greifbar. Im Rahmen dieser Untersuchungen - speziell zur möglichen Implementierung der Raman-Technik - wird ein, hochsensitives Spektrometer, zur direkten Ankopplung an die Stichsonde und eine neuartige Raman-Sonde zur kontaktlosen Messung aus großen Abständen entwickelt und aufgebaut.

description: The isovector spin-flip M1 strength function in the deformed heavy nuclei 156Gd and 238U is calculated in the quasiparticle random-phase approximation. Interaction parameters are adjusted to reproduce the energies of isobaric-analog and Gamow-Teller excitations observed in (p,n) charge-exchange reactions. A phenomenological spreading width for decay into background 2p2h states is introduced and adjusted to reproduce the M1 spin-flip strength function recently observed by elastic scattering of tagged photons on 90Zr and 208Pb. With the model parameters fixed in this fashion, our calculations predict large quantities of spin-flip M1 strength (10–20 µ2N) between 5 and 10 MeV excitation in 156Gd and 238U; it is strongly fragmented and should be observable by tagged-photon elastic scattering and proton inelastic scattering but probably not in high resolution inelastic electron scattering.

description: A Galilean-noninvariant correction to ordinary one-boson-exchange potentials is derived. It gives rise to a three-body force in the three-nucleon system. Its importance for the properties of the three-nucleon bound state is tested and found to be small. This result justifies the common practice which neglects the dependence of the one-boson-exchange potentials on the total momentum of the interacting pair in many-nucleon systems.

description: The “discovery“ of America and the accompanying convergence of cultures unsettled and altered the view of the world of everyone involved. The present study enriches our understanding of events that shape international relations and the cultural identities to this day. Little known archival material is used to reconstruct how members of the Order of Our Lady of Mercy (Mercedarians) reached the Andes in the retinue of the European invaders and participated in the formation of the colonial society. Besides investigating the friars’ role in the colonial and civil wars, as well as in the decades of indigenous resistance, the study also looks at secular legislation, rivalry with other Orders and clergy, as well as prominent examples of Mercedarian missionary work. An analysis of the Order’s reform and of the transatlantic relations of its provinces uncovers that it was only thanks to the works created by the Mercedarian chroniclers of the 17th century that the mission was wholly integrated into the Order’s self-perception. 
This text is a translation of chapter 7 Schlussfolgerungen (‘conclusions’) (pp. 548-566) of my doctoral thesis ‘Expansion und Aktivitäten des Mercedarier-Ordens im Andenraum des 16. Jahrhunderts’.

description: In this paper, we present a novel approach to determine the stability of switched linear and nonlinear systems using Sum of Squares optimisation. Particularly, we use Sum of Squares optimisation to search for a Lyapunov function that defines an absorbing set that confines solution trajectories. For linear systems, we show that this also implies global asymptotic stability. Using this approach, we can study stability for a broader range of switched systems, particularly, we can search for a global attractor for switched nonlinear systems, whose dynamics are given by polynomial vector fields and which have multiple equilibria or limit cycles.

description: The question of whether one can consistently define and extract nucleon-delta scattering parameters, phase shifts, and inelasticities from the partial-wave NN→NΔ amplitudes is discussed. We have studied the unitarity relation and identified the conditions under which the extraction of such quantities is meaningful. Then these conditions were tested in several coupled-channel models of the NN-NΔ system.

description: The modelling of censored survival data is based on different estimations of the conditional hazard function. When survival time follows a known distribution, parametric models are useful. This strong assumption is replaced by a weaker in the case of semiparametric models. For instance, the frequently used model suggested by Cox is based on the proportionality of hazards. These models use non-parametric methods to estimate some baseline hazard and parametric methods to estimate the influence of a covariate. An alternative approach is to use smoothing that is more flexible. In this paper, two types of kernel smoothing and some bandwidth selection techniques are introduced. Application to real data shows different interpretations for each approach. The extensive simulation study is aimed at comparing different approaches and assessing their benefits. Kernel estimation is demonstrated to be very helpful for verifying assumptions of parametric or semiparametric models and is able to capture changes in the hazard function in both time and covariate directions.

description: A relativistic description of polarized deep-inelastic lepton scattering from polarized nuclei is presented. It is based on front form dynamics. Convolution formulas for the nuclear spin structure functions gA1 and gA2 are derived. They require the front form spin distributions of nuclei and the nucleonic spin structure functions. The description is applied to the deuteron and the trinucleon bound states. The numerical calculations show that relativistic effects arising from the consistent quantum mechanical treatment of spin are small. Simple approximations to the convolution formulas for gA1 and gA2 are justified. The approximative convolution formulas allow the subtraction of nuclear effects from measured spin structure functions and therefore the experimental determination of the neutron spin structure functions. Polarized 3He turns out to be a rather reliable effective neutron spin target for deep-inelastic scattering of polarized leptons. The differences between descriptions based on front form and on instant form dynamics are also discussed.

description: Over the last decade, there have been considerable efforts to observe non-abelian quasi-particles in novel quantum materials and devices. These efforts are motivated by the goals of demonstrating quantum statistics of quasi-particles beyond those of fermions and bosons and of establishing the underlying science for the creation of topologically protected quantum bits. In this review, we focus on efforts to create topological superconducting phases hosting Majorana zero modes. We consider the lessons learned from existing experimental efforts, which are motivating both improvemensts to current platforms and exploration of new approaches. Although the experimental detection of non-abelian quasi-particles remains challenging, the knowledge gained thus far and the opportunities ahead offer high potential for discovery and advances in this exciting area of quantum physics.

description: We study the Gregory-Laflamme instability of a large uniform black brane wrapping a two-sphere compactification manifold. This paper extends the work arXiv:hep-th/0604015, where the compactifications on p-torus were considered. The new features of the spherical case are the non-zero curvature of the compactification manifold and the absence of the rescaling symmetry due to a built-in stabilization mechanism. We calculate the order of the phase transition in dependence on the number d of extended dimensions using the Landau-Ginzburg approach. It is found that for d > 11 a uniform spherical black brane in microcanonical ensemble exhibits a smooth second order phase transition towards a stable branch of non-uniform black brane solutions. The critical number of extended dimensions, for which there is a change in the order of the phase transition, is different for microcanonical and canonical ensembles and does not coincide with the critical number of dimensions in the case of the flat toric compactifications. We briefly discuss the origin of this mismatch in the orders of phase transition for the different ensembles.

name: Niendorf, Thomas
name: Mittelstedt, Christian
Publisher: name: MDPI
Year: 2023

description: Thin-walled and cellular structures are characterised by superior lightweight potential due to their advantageous stiffness to weight ratio. They find particular interest in the field of additive manufacturing due to robust and reproducible manufacturability. However, the mechanical performance of such structures strongly depends on the manufacturing process and resultant geometrical imperfections such as porosity, deviations in strut thickness or surface roughness, for which an understanding of their influence is crucially needed. So far, many authors conducted empirical investigations, while analytical methods are rarely applied. In order to obtain efficient design rules considering both mechanical properties and process induced characteristics, analytical descriptions are desirable though. Available analytical models for the determination of effective properties are mostly based on the simple advancement of beam theories, mostly ignoring manufacturing characteristics that, however, strongly influence the mechanical properties of additive manufactured thin-walled structures. One example is the miniaturisation effect, a microstructural effect that has been identified as one of the main drivers of the effective elasto-plastic properties of lightweight structures processed by additive manufacturing. The current work highlights the need to quantify further microstructural effects and to encourage combining them into mesostructural approaches in order to assess macrostructural effective properties. This multi-scale analysis of lattice structures is performed through a comparison between effective stiffness calculated through an analytical approach and compression tests of lattice structures, coupled with an investigation of the arrangement of their struts. In order to cover different potential loading scenarios, bending-dominated and stretch-dominated lattice structures made of the commonly used materials 316L and Ti6Al4V are considered, whereby the impact of microstructural phase transformation during processing is taken into account

description: Δ-isobar excitation in the nuclear medium yields an effective three-nucleon force. A coupled-channel formulation of nucleon-deuteron scattering with Δ-isobar excitation developed previously is used. The three-particle scattering equations are solved by a separable expansion of the two-baryon transition matrix below the inelastic threshold of pion production. The effect of Δ-isobar excitation on the spin-averaged differential cross section is studied. The discrepancy between theory and experiment in the diffraction minimum is reduced.

description: A key design consideration in advanced highs strength steels is to take advantage of the transformation-induced plasticity (TRIP) effect arising from the deformation-induced martensitic transformation of metastable austenite, which is strongly related to the austenite mechanical stability. This thesis investigates how the austenite mechanical stability, in the context of the third generation advanced high strength steels, is affected by its size, shape and surrounding phases using coupled microscopic digital image correlation (micro-DIC) and quasi in-situ (electron backscattered diffraction) EBSD testing. The outcomes contribute to a deeper understanding of the TRIP effect and are beneficial to future high-strength steel designs.

description: Laser light is widely used for communication and sensing applications, so the optimal discrimination of coherent states--the quantum states of light emitted by a laser--has immense practical importance. However, quantum mechanics imposes a fundamental limit on how well different coher- ent states can be distinguished, even with perfect detectors, and limits such discrimination to have a finite minimum probability of error. While conventional optical receivers lead to error rates well above this fundamental limit, Dolinar found an explicit receiver design involving optical feedback and photon counting that can achieve the minimum probability of error for discriminating any two given coherent states. The generalization of this construction to larger sets of coherent states has proven to be challenging, evidencing that there may be a limitation inherent to a linear-optics-based adaptive measurement strategy. In this Letter, we show how to achieve optimal discrimination of any set of coherent states using a resource-efficient quantum computer. Our construction leverages a recent result on discriminating multi-copy quantum hypotheses (arXiv:1201.6625) and properties of coherent states. Furthermore, our construction is reusable, composable, and applicable to designing quantum-limited processing of coherent-state signals to optimize any metric of choice. As illustrative examples, we analyze the performance of discriminating a ternary alphabet, and show how the quantum circuit of a receiver designed to discriminate a binary alphabet can be reused in discriminating multimode hypotheses. Finally, we show our result can be used to achieve the quantum limit on the rate of classical information transmission on a lossy optical channel, which is known to exceed the Shannon rate of all conventional optical receivers.

description: A three-dimensional reduction of the two-particle Bethe-Salpeter equation is proposed. The proposed reduction is in the framework of light-front dynamics. It yields auxiliary quantities for the transition matrix and the bound state. The arising effective interaction can be perturbatively expanded according to the number of particles exchanged at a given light-front time. An example suggests that the convergence of the expansion is rapid. This result is particular for light-front dynamics. The covariant results of the Bethe-Salpeter equation can be recovered from the corresponding auxiliary three-dimensional ones. The technical procedure is developed for a two-boson case; the idea for an extension to fermions is given. The technical procedure appears quite practicable, possibly allowing one to go beyond the ladder approximation for the solution of the Bethe-Salpeter equation. The relation between the three-dimensional light-front reduction of the field-theoretic Bethe-Salpeter equation and a corresponding quantum-mechanical description is discussed.

data sharing

description: In 2020, the COVID-19 pandemic resulted in a rapid response from governments and researchers worldwide. As of March 2021, there have been over 122 million confirmed cases, with over 2.7 million people dying as a result of COVID-19. Despite this staggering toll, those who work with pandemic-relevant data often face significant systemic barriers to accessing, sharing or re-using this data. In this paper we report preliminary results for an in-progress qualitative study, where we interviewed data professionals working with COVID-19-relevant data types including social media, mobility, viral genome, testing, infection, hospital admission, and deaths. These data types are variously used for pandemic spread modelling, healthcare system strain awareness, and devising therapeutic treatments for COVID-19. Barriers to data sharing include cost of access to data (primarily certain healthcare sources and mobility data from mobile phone carriers), human throughput bottlenecks, unclear pathways to request access to data, unnecessarily strict access controls and data re-use policies, unclear data provenance, inability to link separate datasources that could collectively create a more complete picture, poor metadata standards, and a lack of computer-suitable data formats.

description: After 100 years of effort, the classification of all the finite subgroups of SU(3) is yet incomplete. The most recently updated list can be found in P.O. Ludl, J. Phys. A: Math. Theor. 44 255204 (2011), where the structure of the series (C) and (D) of SU(3)-subgroups is studied. We provide a minimal set of generators for one of these groups which has order 162. These generators appear up to phase as the image of an irreducible unitary braid group representation issued from the Jones-Kauffman version of SU(2) Chern-Simons theory at level 4. In light of these new generators, we study the structure of the group in detail and recover the fact that it is isomorphic to the semidirect product Z_9 \times Z_3 \rtimes S_3 with respect to conjugation.

description: Abstract: Childbirth is one of the most significant experiences in a woman's life. Over the years, birthing practices have evolved from traditional home births to highly medicalized hospital deliveries. However, with growing interest in holistic and patient-centered care, many women are choosing alternative birthing methods such as water birth and natural labor. Water births, where labor and delivery occur in a tub of warm water, and natural labor, which minimizes medical interventions, are increasingly being embraced for their potential benefits, including pain relief, shorter labor duration, and improved maternal satisfaction. Nurses and midwives play a crucial role in supporting these birthing practices. Their responsibilities include patient education, monitoring maternal and fetal well-being, providing emotional and physical support, ensuring safety, and managing emergencies when necessary. While water births and natural labor have been associated with numerous benefits, they also pose certain challenges, including infection risks, lack of standardized protocols, and limited accessibility. This review article provides an in-depth exploration of water birth and natural labor, emphasizing the nurse’s role in facilitating safe and effective alternative birthing practices. The discussion highlights global trends, research-based evidence, challenges, and future directions for integrating these methods into mainstream maternal care.

description: The reduction of the two-fermion Bethe-Salpeter equation in the framework of light-front dynamics is studied for the Yukawa model. It yields auxiliary three-dimensional quantities for the transition matrix and the bound state. The arising effective interaction can be perturbatively expanded in powers of the coupling constant gs allowing a defined number of boson exchanges; it is divergent and needs renormalization; it also includes the instantaneous term of the Dirac propagator. One possible solution of the renormalization problem of the boson exchanges is shown to be provided by expanding the effective interaction beyond single boson exchange. The effective interaction in ladder approximation up to order g4s is discussed in detail. It is shown that the effective interaction naturally yields the “box counterterm” required to be introduced ad hoc previously. The covariant results of the Bethe-Salpeter equation can be recovered from the corresponding auxiliary three-dimensional quantities.

description: A perturbative approach for the description of elastic and inelastic nucleon-deuteron scattering is developed. Its validity is discussed. The aim of the perturbative approach is the isolation of details of different reaction mechanisms. The dynamics is based on a two-baryon potential allowing for the excitation of a nucleon to a Δ isobar. The coupled-channel potential yields an effective three-nucleon force in three-nucleon scattering. The purely nucleonic reference potential is the charge-dependent CD-Bonn potential.

description: We demonstrate the measurement of single-shot spectra of temporally selected micropulses from a mid-infrared (MIR) free-electron laser (FEL) by upconversion. We achieve the upconversion of FEL pulses at 11 μm using externally synchronized Nd:YAG or microchip laser pulses at 1064 nm to produce sum-frequency mixing (SFM) signals at 970 nm, which are detected by a compact CCD spectrometer without an intensifier. Our experimental system is very cost-effective, and allows us to obtain the laser spectra of selected micropulses at any temporal position within a single macropulse from an oscillator-type FEL.

description: Electrodisintegration of the three-nucleon bound state with two-body final states is described. The description uses nucleon degrees of freedom extended to include the excitation of a single nucleon to a Δ isobar. The baryonic interaction and the electromagnetic current couple nucleonic states and states with a Δ isobar. Exact solutions of three-particle scattering equations are employed for the initial and final states of the reactions; due to the excitation of the Δ isobar an effective three-nucleon force is included. The current has one-baryon and two-baryon contributions. Theoretical predictions for the reactions with selected kinematic specifications are given. The role of the Δ isobar in the description of the considered processes is discussed and its effect on observables is quantitatively isolated.

description: Die Arbeit gliedert sich in vier Themenblöcke aus der Übergangsmetallkoordinationschemie mit synthetisierten Silyl-substituierten Thioether-Liganden. Dabei standen die Kupfer(I)-halo¬ge¬nide im Fokus. Im ersten Teil konnte mit 1,3-Dithian-substituierten Liganden eine Vielzahl von molekularen und polymeren Komplexen synthetisiert und strukturell aufgeklärt werden. Sowohl monometallische Komplexe der Kupfer(I)-halogenide als auch bimetallische Komplexe, bestehend aus den Halogeniden der Zinkgruppenelemente und Kupfer(I)-halogenide, konnten untersucht werden. Im zweiten Teil wurden die Bindungssituationen von Kupfer(I)-iodid-Koordinationspolymeren analysiert, die selten beobachtete π-koordinierende C–C-Doppelbindungen enthielten. Es konnte gezeigt werden, dass Si- und Ge-gebundene Vinyl-Funktionen durch Polarisationseffekte elektronisch angereichert werden und so, anders als im C-Homolog, mit Kupfer(I)-iodid wechselwirken konnten. Der dritte Teil beschreibt die Synthese von α-Silylthioethern, deren Struktur vom Thioanisol abgeleitet wurde. Drei der synthetisierten, monodentaten Liganden bildeten quadratisch-planare Palladium(II)-chlorid trans-Komplexe, deren temperaturabhängige Konfigurations¬stabilität im Festkörper und in Lösung untersucht wurde. Im vierten Teil konnte über UV-induzierte Thiol-En-Reaktionen eine Reihe von sechs β-Silylthioethern synthetisiert werden, welche mit Kupfer(I)-iodid eindimensionale Koordinationspolymere bildeten. Abhängig vom Substitutionsmuster am Liganden wurden Komplexe mit dimeren oder mit tetrameren Metalleinheiten strukturell aufgeklärt. Für die metallreichen Koordinationspolymere konnten phosphoreszierende Eigenschaften beobachtet und charakterisiert werden.

description: We fit a functional form for a universal ICM entropy profile to the scaled entropy profiles of a catalogue of X-ray galaxy cluster outskirts results, which are all relaxed cool core clusters at redshift below 0.25. We also investigate the functional form suggested by Lapi et al. and Cavaliere et al. for the behaviour of the entropy profile in the outskirts and find it to fit the data well outside 0.3r200 . We highlight the discrepancy in the entropy profile behaviour in the outskirts between observations and the numerical simulations of Burns et al., and show that the entropy profile flattening due to gas clumping calculated by Nagai & Lau is insufficient to match observations, suggesting that gas clumping alone cannot be responsible for all of the entropy profile flattening in the cluster outskirts. The entropy profiles found with Suzaku are found to be consistent with ROSAT, XMM-Newton and Planck results.

description: A two-baryon coupled-channel potential is developed. It couples two-nucleon states and states in which one nucleon is turned into a Δ isobar. It is developed as extension of the purely nucleonic charge-dependent (CD) Bonn potential. It is fitted to two-nucleon scattering data up to 350 MeV nucleon lab energy. Since scattering energies just touch the pion-production threshold, the Δ isobar is considered a stable baryon. The resulting fit of the coupled-channel potential is of the same quality as that for CD Bonn. The coupled-channel potential is as realistic as CD Bonn and as any other modern two-nucleon potential. It is charge-dependent as CD Bonn. It is employed for the description of elastic and inelastic three-nucleon scattering. The Δ isobar yields an effective three-nucleon force in the three-nucleon system, besides other effects. Δ-isobar effects in three-nucleon scattering are isolated and discussed.
