description: Detection of surgical instruments plays a key role in ensuring patient safety in minimally invasive surgery. In this paper, we present a novel method for 2D vision-based recognition and pose estimation of surgical instruments that generalizes to different surgical applications. At its core, we propose a novel scene model in order to simultaneously recognize multiple instruments as well as their parts. We use a Convolutional Neural Network architecture to embody our model and show that the cross-entropy loss is well suited to optimize its parameters which can be trained in an end-to-end fashion. An additional advantage of our approach is that instrument detection at test time is achieved while avoiding the need for scale-dependent sliding window evaluation. This allows our approach to be relatively parameter free at test time and shows good performance for both instrument detection and tracking. We show that our approach surpasses state-of-the-art results on in-vivo retinal microsurgery image data, as well as ex-vivo laparoscopic sequences.

Engineering the Quantum Foam

description: In 1990 Alcubierre, within the General Relativity model for space-time, proposed a scenario for `warp drive' faster than light travel, in which objects would achieve such speeds by actually being stationary within a bubble of space which itself was moving through space, the idea being that the speed of the bubble was not itself limited by the speed of light. However that scenario required exotic matter to stabilise the boundary of the bubble. Here that proposal is re-examined within the context of the new modelling of space in which space is a quantum system, viz a quantum foam, with on-going classicalisation. This model has lead to the resolution of a number of longstanding problems, including a dynamical explanation for the so-called `dark matter' effect. It has also given the first evidence of quantum gravity effects, as experimental data has shown that a new dimensionless constant characterising the self-interaction of space is the fine structure constant. The studies here begin the task of examining to what extent the new spatial self-interaction dynamics can play a role in stabilising the boundary without exotic matter, and whether the boundary stabilisation dynamics can be engineered; this would amount to quantum gravity engineering.

description: Time-resolved Kerr rotation spectroscopy is used to monitor the room temperature electron spin dynamics of optical telecommunication wavelength AlInGaAs multiple quantum wells lattice-matched to InP. We found that electron spin coherence times and effective g-factors vary as a function of aluminum concentration. The measured electron spin coherence times of these multiple quantum wells, with wavelengths ranging from 1.26 microns to 1.53 microns, reach approximately 100 ps at room temperature, and the measured electron effective g-factors are in the range from -2.3 to -1.1.

description: Platelet activation underlies the pathology of an acute myocardial infarction (AMI), and dual antiplatelet therapy (DAPT) is administered post-AMI to limit this activation. Platelets express Toll-like receptors (TLRs) 1, 2, and 4 and become potently activated in response to TLR2/1 and TLR4 stimulation. However, it is unknown whether antiplatelet agents can protect against platelet activation via these TLR pathways. This study aimed to determine the extent to which TLR-mediated platelet activation can be inhibited by currently used antiplatelet agents. Ten healthy subjects were enrolled into a single-blinded randomized cross-over trial. Subjects received either aspirin monotherapy or DAPT (aspirin in combination with ticagrelor) for 1 week, were washed out, and crossed over to the other drug regimen. Platelet activation was assessed in response to Pam3CSK4 (a TLR2/1 agonist) and lipopolysaccharide (LPS; a TLR4 agonist) at baseline and after each antiplatelet drug regimen. Platelet-surface expression of CD62p and PAC1 by flow cytometry was measured as markers of platelet activation. At baseline, expression of CD62p and PAC1 increased significantly in response to high-dose LPS and in a dose-dependent manner in response to Pam3CSK4. Aspirin monotherapy did not inhibit platelet activation in response to any TLR agonist tested. DAPT with aspirin and ticagrelor only modestly inhibited expression of both activation markers in response to high doses of Pam3CSK4 and LPS. However, incubation with these TLR agonists led to substantial platelet activation despite treatment with these anti-platelet agents. Platelet-TLR2/1 and platelet-TLR4 represent intact on-treatment platelet activation pathways, which may contribute to on-going platelet activation post-AMI.

description: The one-loop effective action corresponding the general model of dilaton gravity given by the Lagrangian $L=-\sqrt{g} \left[ \frac{1}{2}Z(Φ) g^{μν} \partial_μΦ\partial_νΦ+ C(Φ) R + V (Φ)\right]$, where $Z(Φ)$, $ C(Φ)$ and $V (Φ)$ are arbitrary functions of the dilaton field, is found. The question of the quantum equivalence of classically equivalent dilaton gravities is studied. By specific calculation of explicit examples it is shown that classically equivalent quantum gravities are also perturbatively equivalent at the quantum level, but only on-shell. The renormalization group equations for the generalized effective couplings $Z(Φ)$, $ C(Φ)$ and $V (Φ)$ are written. An analysis of the equations shows, in particular, that the Callan-Giddings-Harvey-Strominger model is not a fixed point of these equations.

description: Materials with strong spin-orbit interactions are presently a main target in the search for systems with novel magnetic properties. Magnetic anisotropies can be very large in such compounds, ranging from strongly frustrated Kitaev exchange in honeycomb iridates and the associated spin-liquid states to robust antisymmetric couplings in square-lattice Sr_2IrO_4 . Here we predict from ab initio quantum chemistry calculations that another highly unusual regime is realized in pyrochlore iridium oxides: the nearest-neighbor Heisenberg interaction can vanish whilst the antisymmetric Dzyaloshinskii- Moriya exchange reaches values as large as 5 meV, a result which challenges common notions and existing phenomenological models of magnetic superexchange. The resulting spin excitation spectra reveal a very flat magnon dispersion in the Nd- and Tb-based pyrochlore iridates, suggesting the possibility of using these modes to store magnetic information. Indeed the magnetization dynamics indicates that these modes are unable to propagate out of the excitation region.

description: Many-body perturbation theory is often formulated in terms of an expansion in the dressed instead of the bare Green's function, and in the screened instead of the bare Coulomb interaction. However, screening can be calculated on different levels of approximation, and it is important to define what is the most appropriate choice. We explore this question by studying a zero-dimensional model (so called 'one-point model') that retains the structure of the full equations. We study both linear and non-linear response approximations to the screening. We find that an expansion in terms of the screening in the random phase approximation is the most promising way for an application in real systems. Moreover, by making use of the nonperturbative features of the Kadanoff-Baym equation for the one-body Green's function, we obtain an approximate solution in our model that is very promising, although its applicability to real systems has still to be explored.

description: We report on SN 1997bs in NGC 3627 (M66), the first supernova discovered by the Lick Observatory Supernova Search using the 0.75-m Katzman Automatic Imaging Telescope (KAIT). Based on its early-time optical spectrum, SN 1997bs was classified as Type IIn. However, from the BVRI light curves obtained by KAIT early in the supernova's evolution, and F555W and F814W light curves obtained from Hubble Space Telescope archival WFPC2 images at late times, we question the identification of SN 1997bs as a bona fide supernova. We believe that it is more likely a super-outburst of a very massive luminous blue variable star, analogous to Eta Carinae, and similar to SN 1961V in NGC 1058 (Filippenko et al. 1995 [AJ, 110, 2261]) and SN 1954J (``Variable 12'') in NGC 2403 (Humphreys & Davidson 1994 [PASP, 106, 1025]). The progenitor may have survived the outburst, since the SN is seen in early 1998 at m_F555W=23.4, about 0.5 mag fainter than the progenitor identified by Van Dyk et al. (1999, [AJ, 118, 2331]) in a pre-discovery image. Based on analysis of its environment in the Hubble Space Telescope images, the progenitor was not in an H II region or association of massive stars. The recent discovery of additional objects with properties similar to those of SN 1997bs suggests that the heterogeneous class of Type IIn supernovae consists in part of ``impostors.''

Using zeta-function regularization and heat-kernel techniques, we derive the one-loop effective Lagrangian up to second order in the variation of the background field and up to quadratic terms in the curvature tensors. Specializing to different spacetimes of physical interest, the influence of the curvature on the phase transition is considered.

Mechanisms of fatigue crack nucleation near non-metallic inclusions in Ni-based superalloys
Creators: name: Bergsmo, Alexander Hoggan
Publisher: name: Imperial College London
Year: 2021

description: Ni-based superalloys used for turbine discs are typically produced via powder metallurgy, a process which introduces undesirable non-metallic inclusions. Inclusions can be regarded as fatigue crack nucleation hot-spots due to their differing mechanical properties compared with the matrix they are embedded in. In this thesis, a series of models and experiments were used to investigate the mechanistic drivers of fatigue crack nucleation in the vicinity of non-metallic inclusions. The drivers of decohesion and fracture of inclusions, often precursors to crack nucleation, were found to be the normal stress acting on the interface and the inclusion maximum principal stress, respectively. Exact values of either criterion were found using a cohesive zone model in a crystal plasticity finite element (CPFE) model faithfully representative of a real microstructure under low cycle fatigue. Decohesion and inclusion fracture were contrasted against slip-driven nucleation by a stored energy criterion. The key finding here was that decohesion and inclusion fracture marginally reduce fatigue life. The comparative fatigue performance of an inclusion, a twin boundary and a triple-junction were studied in a synthetic CPFE microstructure. The inclusion recorded a significantly lower fatigue life compared with the intrinsic microstructural features. Various hardening models were used to investigate cyclic decohesion in a stress-controlled regime. Under no hardening model was cyclic decohesion predicted, strongly suggesting that decohesion is purely a function of applied stress within the first cycle. A discontinuity tolerant digital image correlation algorithm was developed to study fatigue crack nucleation near a non-metallic agglomerate at 300°C. Decohesion and fracture of inclusions occurred already within the first cycle of loading. Microcracks nucleated throughout the inclusion agglomerate after 6000 cycles. In addition, a fatigue crack nucleated adjacent a twin boundary in a coarse grain neighbouring the agglomerate. A high (angular) resolution electron backscatter diffraction (HR-EBSD) analysis and a discrete dislocation plasticity (DDP) model suggested that strong build-up of GNDs and slip near twin boundary owes to the elastic anisotropy of twin and parent.

description: An der Ruhr-Universität Bochum gibt es keine DH-Studiengänge, daher sollen ab dem Studienjahr 2025/2026 Zertifikate in den Digital Humanities (DH) angeboten werden. Die bereits vorhandene Lehre wird so gebündelt und durch neue Selbstlern- und Präsenzangebote ergänzt, um eine umfassende DH-Grundlagenausbildung zu gewährleisten. Der Fokus liegt auf Textverarbeitung und -analyse. Zusätzlich werden offene Bildungsressourcen (OER) entwickelt, um bestehende Lücken zu schließen. Durch die Zusammenarbeit mit der Universität Duisburg-Essen und der Technischen Universität Dortmund werden Studierende auch universitätsübergreifend Kurse belegen können. Eine Kompetenzmatrix, basierend auf Literaturrecherche und Interviews, identifiziert die für die Digital Humanities notwendigen "atomic skills" und ordnet sie in sechs Bereiche ein. Diese Bereiche umfassen Grundlagen der DH, Umgang mit dem PC, Programmierung,, Statistik, DH-Tools und -Methoden sowie die DH-Projektarbeit. Ziel ist es, Lücken im Lehrangebot zu schließen und die Kompetenzen über entsprechende Module in den Optionalbereich der Ruhr-Universität zu integrieren. Studierende können durch das Absolvieren bestimmter Modulkombinationen DH-Zertifikate erwerben.

description: Mixed spin chain compounds, ACuFe2(VO4)3 (A= Li,Na), reach magnetically ordered state at TN ~ 11 K (Li) or ~ 9 K (Na) and experience further transformation of magnetic order at T* ~ 7 K (Li) or ~ 5 K (Na), evidenced in magnetic susceptibility chi and specific heat Cp measurements. While no anomaly has been detected in dielectric property of NaCuFe2(VO4)3, the step-like feature precedes a sharp peak in permittivity epsilon at TN in LiCuFe2(VO4)3. These data suggest the spin-order-induced ferroelectricity in Li compound and no such thing in Na compound. On the contrary, the Moessbauer spectroscopy study suggests similarly wide distribution of hyperfine field in between T* and TN for both the compounds. The first principles calculations also provide similar values for magnetic exchange interaction parameters in both compounds. These observations lead us to conclude on the crucial role of alkali metals mobility within the channels of the crystal structure needed to be considered in explaining the improper multiferroicity in one compound and its absence in other.

description: We consider an Ising spin-chain in a random transverse magnetic field and compute the zero temperature wave vector and frequency dependent dynamic structure factor numerically by using Jordan-Wigner transformation. Two types of distributions of magnetic fields are introduced. For a rectangular distribution, a dispersing branch is observed, and disorder tends to broaden the dispersion peak and close the excitation gap. For a binary distribution, a non-dispersing branch at almost zero energy is recovered. We discuss the relationship of our work to the neutron scattering measurement in $\mathrm{LiHoF_4}$.

description: Generalized analytic signal associated with the linear canonical transform (LCT) was proposed recently by Fu and Li ["Generalized Analytic Signal Associated With Linear Canonical Transform," Opt. Commun., vol. 281, pp. 1468-1472, 2008]. However, most real signals, especially for baseband real signals, cannot be perfectly recovered from their generalized analytic signals. Therefore, in this paper, the conventional Hilbert transform (HT) and analytic signal associated with the LCT are concerned. To transform a real signal into the LCT of its HT, two integral transforms (i.e., the HT and LCT) are required. The goal of this paper is to simplify cascades of multiple integral transforms, which may be the HT, analytic signal, LCT or inverse LCT. The proposed transforms can reduce the complexity when realizing the relationships among the following six kinds of signals: a real signal, its HT and analytic signal, and the LCT of these three signals. Most importantly, all the proposed transforms are reversible and undistorted. Using the proposed transforms, several signal processing applications are discussed and show the advantages and flexibility over simply using the analytic signal or the LCT.

Abstract
Das Projekt „Forschen lernen – Lernen erforschen!“ am Oberstufen-Kolleg Bielefeld

description: Im Beitrag werden die Ziele, das Konzept und die Erfahrungen eines Projekts zum Forschenden Lernen mit Schüler*innen (Kollegiat*innen) am Oberstufen-Kolleg vorgestellt. Innerhalb der in jedem Schulhalbjahr stattfindenden zweiwöchigen Projektphase konnten die Kollegiat*innen in diesem Projekt selbst gestellten Fragestellungen mittels sozialwissenschaftlicher Forschungsmethoden nachgehen. Die Erfahrungen zeigen, dass die Ziele, die mit dem Forschenden Lernen verbunden sind, zwar erreicht werden können, dass aber die zwei Wochen in der Projektphase recht kurz sind und deshalb die Anbindung an den Kursunterricht außerhalb der Projektphase sinnvoll sein könnte. Entwickelt und durchgeführt wurde das Projekt durch einen Professor der Erziehungswissenschaft der Johannes-Gutenberg-Universität Mainz und zwei Studentinnen der Universität Bielefeld. The article presents the goals and the concept of and the experiences from a project on research-based learning with students at the Oberstufen-Kolleg (laboratory school for upper secondary education). During the two-weeks project phase, which takes place every half year, the students of this project were able to pursue their own questions using research methods from social sciences. Results show that although the goals associated with the research-based learning can be achieved, two weeks within the project phase are rather short. Therefore, the connection to regular classes besides the project phase might be useful. The project was developed and carried out by a Professor of Educational Science from the Johannes-Gutenberg-University of Mainz and two students from the University of Bielefeld.

description: We report on the realization of a sputter deposition system for the in situ- and in operando-use in polarized neutron reflectometry experiments. Starting with the scientific requirements, which define the general design considerations, the external limitations and boundaries imposed by the available space at a neutron beamline and by the neutron and vacuum compatibility of the used materials, are assessed. The relevant aspects are then accounted for in the realization of our highly mobile deposition system, which was designed with a focus on a quick and simple installation and removability at the beamline. Apart from the general design, the in-vacuum components, the auxiliary equipment and the remote control via a computer, as well as relevant safety aspects are presented in detail.

description: In the first order form, the model considered by Strobl presents, besides local Lorentz and diffeomorphism invariances, an additional local non-linear symmetry. When the model is realized as a Poincaré gauge theory according to the procedure outlined in Refs.[1,2], the generators of the non-linear symmetry are responsible for the ``nasty constraint algebra''. We show that not only the Poincaré gauge theoretic formulation of the model is not the cause of the emerging of the undesirable constraint algebra, but actually allows to overcome the problem. In fact one can fix the additional symmetry without breaking the Poincaré gauge symmetry and the diffeomorphisms, so that, after a preliminary Dirac procedure, the remaining constraints uniquely satisfy the Poincaré algebra. After the additional symmetry is fixed, the equations of motion are unaltered. The objections to our method raised by Strobl in Ref.[3] are then immaterial. Some minor points put forward in Ref.[3] are also discussed.

Projektdidaktik in der Praxis

description: Der Artikel fasst wesentliche Ergebnisse der Feldstudie „Projektdidaktik in der Praxis“ zusammen. Der Autor skizziert den Entstehungskontext und das Methodensetting seiner Untersuchung, um dann Bausteine der Projektdidaktik herauszuarbeiten und weiterzuentwickeln. Ausgehend von der zuvor noch nicht aufgearbeiteten Praxisgeschichte des Projektunterrichts wird die didaktische Konzeption mit Bildungswert, praxistauglichem Projektbegriff und Abgrenzung zum Lehrgang entwickelt. Eine differenzierte Methodik mit Kriterienkatalog, idealtypischem Verlaufsmuster und einer Typologie der Projektformen sind Grundlage der Erörterung der Leistungsbewertung. Am Fach Geschichte wird exemplifiziert, wie sich Lehrgang und Projekt verbinden und gegenseitig unterstützen können. Zentral ist dann die Untersuchung der organisatorischen Bedingungen für entwickelten Projektunterricht mit der Bestimmung von „Projektkultur“, die anhand einer Merkmalsliste als Untersuchungsinstrument an sechs Regelschulen diente. Alle Entwicklungsschritte münden in einer abschließenden Erörterung von Formen, Möglichkeiten und Grenzen des Transfers von der Versuchsschule in das Regelsystem. This article summarizes significant results from the field study “Project Didactics in Practice”. The author outlines the formation context and the methodological setting of his research, then elaborates components of project didactics and develops them further. Based on a history of the practice of project-based instruction, which was not examined so far, he depicts the didactical conception and its educational asset, gives a practicable definition of the term “project”, and delimitates it from the “regular” course. Based on a differentiated method with a catalogue of criteria, an ideal progression pattern and a typology of project forms, the author discusses possibilities to assess project performance. Using the example of the subject History, he shows how course and project can be combined and may support each other mutually. The survey focuses on the organizational requirements of sophisticated project-based instruction, defining a so-called “project culture”, which was used as research instrument (with a list of typical characteristics) at six regular schools. All these steps lead to a discussion of forms, opportunities and limits of a transfer of project didactics from the laboratory school to the regular school system.

description: We study Bose-Einstein condensates with purely dipolar interactions in oblate (pancake) traps. We find that the condensate always becomes unstable to collapse when the number of particles is sufficiently large. We analyze the instability, and find that it is the trapped-gas analogue of the ``roton-maxon'' instability previously reported for a gas that is unconfined in two dimensions. In addition, we find that under certain circumstances, the condensate wave function attains a biconcave shape, with its maximum density away from the center of the gas. These biconcave condensates become unstable due to azimuthl excitation - an angular roton.

description: Im Rahmen der wissenschaftlichen Begleitung von zwei Versuchsschulen arbeiten die Autor*innen des Beitrags seit einigen Jahren mit qualitativ-rekonstruktiven Verfahren der Schul- und Unterrichtsforschung. Dabei stellt sich die Kooperation zwischen Schule und Wissenschaft jeweils unterschiedlich dar: Während im Oberstufen-Kolleg Wissenschaftler*innen und Lehrer*innen in partizipativen Forschungs- und Entwicklungsprojekten zusammenarbeiten, findet an der Helene-Lange-Schule eine evaluative Begleitung der Schulpraxis durch die Wissenschaftler*innen statt. Für beide Vorgehensweisen einer praxisnahen Schulforschung stellt sich, allerdings in unterschiedlicher Weise, das Verhältnis von Nähe und Distanz als zentrales Problem dar, das zugespitzt wie folgt beschrieben werden kann: Während im Oberstufen-Kolleg die Involviertheit der forschenden Lehrer*innen in die Schulpraxis bzw. die Erforschung der eigenen Praxis den für Forschung notwendigen distanzierten Blick verhindert, erschwert im Rahmen der Evaluationsforschung die Systemdifferenz von Wissenschaft und Schulpraxis die Anschlussfähigkeit von Forschungsbefunden. Für beide Zugänge stellt sich die Anonymisierung von Daten und Befunden als eine (weitere) Herausforderung dar. Im Ausblick wird die Etablierung eines Netzwerks von Schulen und Wissenschaftler*innen als potenzielle Problemlösung vorgeschlagen. As part of the scientific monitoring of two laboratory schools, the authors of the article have been working for several years with qualitative-reconstructive methods of school and teaching research. The cooperation between school and research is different in each case: While researchers and teachers work together in participative research and development projects in the Oberstufen-Kolleg, the Helene Lange School provides evaluative support for school practice by the researchers. For both approaches to practice-oriented school research, the relationship between nearness and distance presents itself as a central problem, albeit in a different way: While in the Oberstufen-Kolleg the involvement of the researching teachers in school practice or the research of their own practice prevents the distanced view necessary for research, in the context of evaluation research the system difference between research and school practice makes it more difficult for research findings to be connected. For both approaches, the anonymization of data and findings presents a (further) challenge. In the outlook, we propose the establishment of a network of schools and researchers as a possible solution to the problem.
