Diagnostik und Therapie aus der Patientenperspektive - PROMs in der Chirurgie
Authors: Kostuj Tanja , Niemeyer Anna 
Published: April 2022

Zusammenfassung/AbstractDie zunehmend an Bedeutung gewinnenden Patient reported Outcome and Experience Measures (PROMs/PREMs) können in allen chirurgischen Disziplinen zusätzlich zu den klassischen harten
Endpunkten wie z. B. Überlebenskurven und Implantatestandzeiten wichtige Informationen zu Qualitätsindikatoren oder Entscheidungshilfen zu konkurrierenden Therapieverfahren liefern. Dies
gilt ebenso für die Evaluation neuer Therapiekonzepte wie für Vergleiche klassisch offener Zugangswege und minimalinvasiver bzw. endoskopischer Verfahren z. B. im Hinblick auf geringere
Zugangsmorbidität und schnellere Rehabilitation vs. höherem Komplikationsrisiko, aber auch der Risiko-Nutzen-Bewertung der Verlängerung der Lebenszeit einerseits auf Kosten einer
Beeinträchtigung der Lebensqualität andererseits.Diesem Zusatznutzen steht ein notwendiger Ressourceneinsatz (Personal- und Sachkosten für Postversand oder für eine Onlineerhebung in Form von Entwicklungs-, Bereitstellungs- oder Lizenz-
und Servicekosten) gegenüber, der sich nur bedingt beeinflussen lässt (z. B. Portokosten für eine Vollerhebung vs. repräsentative Stichprobe). Die zentrale Voraussetzung für den
erfolgreichen Einsatz von PROMs und PREMs ist jedoch, dass geeignete, sprachlich und inhaltlich validierte Erhebungsinstrumente verfügbar sind oder durch einen Validierungsprozess zur
Verfügung gestellt werden können.Für den Einsatz von PROMs bei konkurrierenden Therapieansätzen findet sich bereits eine Reihe von Beispielen, die wertvolle Unterstützung bieten und sich im Klinikalltag etabliert haben. So
können sie bei belastenden Therapieansätze in der chirurgischen Tumortherapie bei Entscheidungen über ein verbessertes Überleben bei starker Belastung vs. dem Erhalt oder sogar Zugewinn an
Lebensqualität unterstützen. In der onkologischen Mammachirurgie steht die Lebensqualität bei brusterhaltendem Vorgehen häufig der Überlebenszeit bezogen auf das TU-Stadium bei Ablation
gegenüber. Ebenso gilt es bei Prostatakarzinompatienten, immer wieder zwischen invasiver Therapie und Verlaufsbeobachtung (Überleben vs. Inkontinenz und Potenzstörungen) zu entscheiden. In
der Orthopädie/Unfallchirurgie gibt es bei einer Reihe von Eingriffen häufig eine Alternative, z. B. Sprunggelenkendoprothesen vs. Arthrodesen oder inverse Schulterprothesen vs.
Osteosynthese bei schultergelenknahen Humerusfrakturen.Aber auch bei der Evaluation neuer Therapiekonzepte (z. B. der subjektive Aspekt einer früheren Wiedererlangung der Selbstständigkeit durch Einführung neuer Nachbehandlungskonzepte/sog.
Fast-Track-Reha) sind PROMs und PREMS wichtige Werkzeuge.
Das Ampullenkarzinom – prognostische und therapeutische Unterschiede zum duktalen Adenokarzinom des Pankreas
Authors: Giehl-Brown Esther , Weitz Jürgen , Distler Marius 
Published: April 2022

ZusammenfassungDas Ampullenkarzinom stellt eine seltene, jedoch in seiner Inzidenz steigende Entität gastrointestinaler Tumoren dar. Aufgrund der anatomischen Lokalisation führt es vergleichsweise früh im
Erkrankungsprozess zu einer biliären Gangobstruktion, wodurch eine schnellere Diagnosestellung erleichtert und eine bessere Prognose bedingt werden. Adenome der Ampulla hepatopancreatica und
der Papilla duodeni major stellen Vorläuferläsionen des Ampullenkarzinoms dar und besitzen ein 30–40%iges Risiko zur malignen Transformation. Diese Entartungstendenz begründet die
Notwendigkeit zur vollständigen/kompletten Abtragung im Rahmen der endoskopischen Therapie. Der Erfolg der endoskopischen Papillektomie wird durch eine Ausdehnung des Befundes in den
Pankreashauptgang oder Ductus choledochus erschwert. Endoskopisch nicht sanierbare Adenome und Ampullenkarzinome stellen Indikationen für chirurgische Therapieverfahren dar. Grundsätzlich
sollte für benigne Befunde die transduodenale Papillenresektion bervorzugt werden, für maligne Befunde stellt die Pankreaskopfresektion mit systematischer Lymphadenektomie und
Level-II-Dissektion des Mesopankreas die onkologisch korrekte Operation dar. Prognostische Faktoren beim Ampullenkarzinom sind: der pankreatobiliäre Subtyp, eine Lymphknoteninfiltration und
eine Perineuralscheideninvasion. Die Differenzierung in histopathologische Subtypen gewinnt zunehmend in der Indikationsstellung zur Systemtherapie an Bedeutung. Der Einsatz der
neoadjuvanten und adjuvanten Therapie für das Ampullenkarzinom konnte bisher nicht klar definiert werden. Jedoch scheinen Patienten mit dem pankreatobiliären Subtyp oder anderen
prognoselimitierenden Faktoren von einer adjuvanten Therapie zu profitieren. Zukünftige Studien werden zur zielgerichteten Therapiefestlegung benötigt.

Published: April 2022

Zusammenfassung
Hintergrund Das prostataspezifische Membranantigen (PSMA) ist für Mammakarzinompatientinnen ein vielversprechendes Protein. Es wurde bisher nicht nur beim Prostatakarzinom nachgewiesen, sondern wird auch von den Tumor- sowie Endothelzellen der Tumorgefäße des Mammakarzinoms exprimiert. Das PSMA hat eine Rolle bei der Tumorprogression und Neubildung von Gefäßen. Deshalb wurden bereits viele PSMA-gerichtete diagnostische und therapeutische Verfahren entwickelt.
Methode Diese Arbeit ist eine allgemeine und gegliederte Übersicht über das PSMA und dessen onkogenetisches Potenzial, mit dem Fokus auf dessen Rolle beim Mammakarzinom. Für dieses narrative Review wurde eine selektive Literaturrecherche via PubMed und der Bibliothek des Universitätsklinikums Freiburg angefertigt. Hierbei wurden folgende Schlüsselwörter verwendet: „PSMA“, „PSMA and breast cancer“, „PSMA PET/CT“, „PSMA tumor progression“. Relevante Artikel wurden explizit durchgelesen, bearbeitet und zusammengefasst.
Schlussfolgerung Das PSMA könnte, insbesondere beim triple-negativen Mammakarzinom, eine neue diagnostische und therapeutische Alternative darstellen. Es scheint ein möglicher prädiktiver und prognostischer Marker zu sein.
Anticipation and timing of turn-taking in dialogue interpreting
Authors: Vranjes Jelena , Oben Bert 
Published: April 2022

Abstract
This article presents the results of an exploratory study on the timing of turn-taking in face-to-face dialogue
interpreting based on a corpus of interpreted interactions that were recorded with mobile eye-trackers. Our aims were to: (1)
investigate the timing of interpreters’ turns in dialogic interaction; and (2) identify features that have an impact on
interpreters’ turn-taking speed. These include input processing factors (including turn type and turn duration) and gaze, which
have been shown to play an important role in turn-taking. The analysis shows that, although interpreters in our study tend to
orient to the maxim ‘one speaker at a time’, turn transitions between the primary speaker and the interpreter contain more gaps
and longer overlaps than have been found for same-language interactions. It also shows that the type of turn produced by the
primary speaker (question vs. non-question), the primary speaker’s speech rate, and, to a certain extent, turn duration affect the
interpreter’s turn-taking speed. Thus, the present study contributes to a better understanding of the processes that impact the
timing of turn-taking in face-to-face dialogue interpreting.
Classical double copy at null infinity
Authors: Adamo Tim , Kol Uri 
Published: April 2022

Abstract
We give two double copy prescriptions which construct asymptotically flat solutions in gravity from asymptotically flat gauge fields. The first prescription applies to radiative fields, which are non-linear vacuum solutions determined by characteristic data at null infinity. For any two such radiative gauge fields (linear or non-linear), the characteristic data of a radiative metric, dilaton and axion is constructed by a simple ‘squaring’ procedure, giving a classical double copy at the level of radiation fields. We demonstrate the procedure with several examples where the characteristic data can be explicitly integrated; for linear fields this also sheds light on the twistorial description of Weyl double copy. Our second prescription applies to all asymptotically flat fields at the level of their asymptotic equations of motion: we give a map between any solution of the asymptotic Maxwell equations and any solution of the asymptotic Einstein equations at null infinity. This also extends to the asymptotic charges and their duals, preserves the soft and hard sectors between gauge theory and gravity, and is related to the usual notion of double copy in scattering amplitudes.
Carrollian manifolds and null infinity: a view from Cartan geometry
Authors: Herfray Yannick 
Published: April 2022

Abstract
We discuss three different (conformally) Carrollian geometries and their relation to null infinity from the unifying perspective of Cartan geometry. Null infinity per se comes with numerous redundancies in its intrinsic geometry and the two other Carrollian geometries can be recovered by making successive choices of gauge. This clarifies the extent to which one can think of null infinity as being a (strongly) Carrollian geometry and we investigate the implications for the corresponding Cartan geometries. The perspective taken, which is that characteristic data for gravity at null infinity are equivalent to a Cartan geometry for the Poincaré group, gives a precise geometrical content to the fundamental fact that ‘gravitational radiation is the obstruction to having the Poincaré group as asymptotic symmetries’.
Increasing stability in the linearized inverse Schrödinger potential problem with power type nonlinearities*
Authors: Lu Shuai , Salo Mikko , Xu Boxi 
Published: April 2022

Abstract
We consider increasing stability in the inverse Schrödinger potential problem with power type nonlinearities at a large wavenumber. Two linearization approaches, with respect to small boundary data and small potential function, are proposed and their performance on the inverse Schrödinger potential problem is investigated. It can be observed that higher order linearization for small boundary data can provide an increasing stability for an arbitrary power type nonlinearity term if the wavenumber is chosen large. Meanwhile, linearization with respect to the potential function leads to increasing stability for a quadratic nonlinearity term, which highlights the advantage of nonlinearity in solving the inverse Schrödinger potential problem. Noticing that both linearization approaches can be numerically approximated, we provide several reconstruction algorithms for the quadratic and general power type nonlinearity terms, where one of these algorithms is designed based on boundary measurements of multiple wavenumbers. Several numerical examples shed light on the efficiency of our proposed algorithms.
Fast, high precision dynamics in quantum optimal control theory
Authors: Dalgaard Mogens , Motzoi Felix 
Published: April 2022

Abstract
Quantum optimal control theory is becoming increasingly crucial as quantum devices become more precise, but the need to quickly optimize these systems classically remains a significant bottleneck in their operation. Here we present a new theoretical quantum control framework for much faster optimization than the state of the art by replacing standard time propagation with a product of short-time propagators, each calculated using the Magnus expansion. The derived formulas for exact series terms and their gradients, based on earlier approximate integrals in a simulation setting, allow us to subsume the high cost of calculating commutators and integrals as an initial overhead. This provides an order of magnitude speedup for quantum control optimization.
Re-analysis of radiative capture11C(p, γ)12N at low energy
Authors: Kabir Abdul , Irgaziev B. F. , Nabi Jameel-Un , Sagheer Sumair 
Published: April 2022

Abstract
Within the framework of the modified potential model, we computed the astrophysical S-factor of the proton radiative capture p + 11C → 12N + γ. At energies bearing astrophysical importance, radiative capture is a key process in the spectroscopic study of 12N. In this work, we consider the radiative capture cross-section for the proton capture by 11C within the framework of the potential model. For the possible electric and magnetic dipole transitions, we computed the partial components of the astrophysical S-factor within the energy range E = (0.01–0.8) MeV. The computed value of the S-factor at zero energy shows satisfactory agreement with the reported results. Furthermore, we computed the radiative capture rates for the selected reaction, which shows a better comparison with the reported data.
Neutron powder-diffraction study of phase transitions in strontium-doped bismuth ferrite: 1. Variation with chemical composition

Abstract
We report results from a study of the crystal and magnetic structures of strontium-doped BiFeO3 using neutron powder diffraction and the Rietveld method. Measurements were obtained over a wide range of temperatures from 300–800 K for compositions between 10%–16% replacement of bismuth by strontium. The results show a clear variation of the two main structural deformations—symmetry-breaking rotations of the FeO6 octahedra and polar ionic displacements that give ferroelectricity—with chemical composition, but relatively little variation with temperature. On the other hand, the antiferromagnetic order shows a variation with temperature and a second-order phase transition consistent with the classical Heisenberg model. There is, however, very little variation in the behaviour of the antiferromagnetism with chemical composition, and hence with the degree of the structural symmetry-breaking distortions. We therefore conclude that there is no significant coupling between antiferromagnetism and ferroelectricity in Sr-doped BiFeO3 and, by extension, in pure BiFeO3.
Dynamical polarization, optical conductivity and plasmon mode of a linear triple component fermionic system
Authors: Dey Bashab , Ghosh Tarun Kanti 
Published: April 2022

Abstract
We investigate the density and optical responses of a linear triple component fermionic system in both non-interacting and interacting regimes by computing its dynamical polarization function, random phase approximation dielectric function, plasmon mode and long wavelength optical conductivity and compare the results with those of Weyl fermions and three-dimensional free electron gas. Linear triple component fermions are pseudospin-1 generalization of Weyl fermions, consisting of two linearly dispersive bands and a flat band. The presence of flat band brings about notable modifications in the response properties with respect to Weyl fermions such as induction of a new region in the particle–hole continuum, increased static polarization, reduced plasmon gap, shift in absorption edge, enhanced rate of increase in energy absorption with frequency and highly suppressed intercone transitions in the long wavelength limit. The plasmon dispersion follows the usual ω ∼ ω

Broadband photoresponse arising from photo-bolometric effect in quasi-one-dimensional Ta2Ni3Se8
Authors: Zhen W L , Miao W T , Zhu W L , Zhang C J , Zhu W K 
Published: April 2022

AbstractIn this paper, we report the synthesis of high-quality Ta2Ni3Se8crystals free of noble or toxic elements and the fabrication and testing of photodetectors on the wire samples. A broadband photoresponse from 405 nm to 1550 nm is observed, along with performance parameters including relatively high photoresponsivity (10 mA W−1) and specific detectivity (3.5 × 107Jones) and comparably short response time (τrise= 433 ms,τdecay= 372 ms) for 1064 nm, 0.5 V bias and 1.352 mW mm−2. Through extensive measurement and analysis, it is determined that the dominant mechanism for photocurrent generation is the photo-bolometric effect, which is believed to be responsible for the very broad spectral detection capability. More importantly, the pronounced response to 1310 nm and 1550 nm wavelengths manifests its promising applications in optical communications. Considering the quasi-one-dimensional structure with layered texture, the potential to build nanodevices on Ta2Ni3Se8makes it even more important in future electronic and optoelectronic applications.
Development of chipscale InGaN RGB displays using strain-relaxed nanosphere-defined nanopillars
Authors: Fu Wai Yuen , Choi Hoi Wai 
Published: April 2022

Abstract
Chip-scale red, green and blue (RGB) light emission on an InGaN/GaN multi-quantum well wafer adopting a top-down fabrication approach is demonstrated in this study, facilitated by shadow-masked nanosphere lithography for precise site-controlled nano-patterning. Exploiting the strain relaxation mechanism by fabricating arrays of nanosphere-defined nanopillars of two different dimensions utilizing a sequential shadow-masked nanosphere coating approach into the blue and green light-emitting pixel regions on a red-light emitting InGaN/GaN wafer, RGB light emission from a monolithic chip is demonstrated. The micro-sized RGB light-emitting pixels emit at 645 nm–680 nm, 510 nm–521 nm and 475 nm–498 nm respectively, achieving a maximum color gamut of 60% NTSC and 72% sRGB. Dimensional fluctuations of the nanopillars of 73% and 71% for the green and blue light-emitting pixels, respectively, are estimated from scanning electron microscope images of the fabricated device, corresponding to fluctuations in spectral blue-shifts of 5.4 nm and 21.2 nm as estimated by strain-coupled k · p Schrödinger calculations, consistent with observations from micro-photoluminescence (μ-PL) mapping which shows deviations of emission wavelengths for the RGB light-emitting pixels to be 8.9 nm, 14.9 nm and 23.7 nm, respectively. The RGB pixels are also configured in a matrix-addressable configuration to form an RGB microdisplay, demonstrating the feasibility of the approach towards chip-scale color displays.

Published: April 2022

Abstract
Actuated by the non-ionic heavy metal of antimony (Sb) contaminants with undesired toxicity to the environment and human health, capturing Sb is urgent to remedy contaminated water. Herein, the lamellar MnCo hydrotalcite was grown on catkin-derived biochar through the in situ etching of ZIF-L to construct a hierarchical microtube@nanosheet hybrid (CLMH) for Sb immobilization. The adsorption behaviour and mechanism of trivalent antimony (Sb (III)) on the CLMH were investigated. The CLMH shows good pH applicability for capturing Sb(III) at pH from 2 to 9. The excellent adsorption capacity of CLMH for Sb(III) is 247.62 mg g−1 at 303 K, and the endothermic process is proved by the positive value of Δ

(10.54 kJ mol−1). The adsorption process is fitted with the intra-particle diffusion model, which can be described with external mass transfer, intraparticle diffusion in pores, and equilibrium stage. The adsorption mechanism is proved, which includes the bind of Metal–O–Sb bonds by inner-sphere complex, the embedding of Sb in the intercalation of hydrotalcite, redox between Mn and Sb, and functional groups dependent anchoring effect. The work benefits the understanding of the antimony removal behaviour over the hierarchical microtube@nanosheet hybrids.

Published: April 2022

Abstract
The impact of 1 MeV proton irradiation on 1.12 eV bandgap InGaAsN solar cells was studied through device and material characterizations. After a 1013 p+cm−2 proton fluence, the photocurrent decreases by 28%, due to the formation of defects in both the GaAs emitter and the InGaAsN absorber. Furthermore, photoluminescence measurements suggest that the proton radiation hardness of InGaAsN increases with the nitrogen.
Ac losses in field-cooled type I superconducting cavities

Published: April 2022

Abstract
As superconductors are cooled below their critical temperature, stray magnetic flux can become trapped in regions that remain normal. The presence of trapped flux facilitates dissipation of ac current in a superconductor, leading to losses in superconducting elements of microwave devices. In type II superconductors, dissipation is well-understood in terms of the dynamics of vortices hosting a single flux quantum. In contrast, the ac response of type I superconductors with trapped flux has not received much attention. Building on Andreev’s early work (Andreev 1967 Sov. Phys. JETP
24 1019), here we show theoretically that the dominant dissipation mechanism is the absorption of the ac field at the exposed surfaces of the normal regions, while the deformation of the superconducting/normal interfaces is unimportant. We use the developed theory to estimate the degradation of the quality factors in field-cooled cavities, and we satisfactorily compare these theoretical estimates to the measured field dependence of the quality factors of two aluminum cavities. We also identify a regime in which the dissipated power depends weakly on the Ginzburg-Landau parameter; this makes it possible to apply our findings to cavities made of other materials, such as niobium.
Impact of thermal and solute source-sink combination on thermosolutal convection in a partially active porous annulus
Authors: Kemparaju S , Kumara Swamy H A , Sankar M , Mebarek-Oudina F 
Published: April 2022

Abstract
The objective of the current paper is to investigate the thermosolutal flow along with heat and mass dissipation rates in an upright porous annular space subjected to discrete heating and salting along the vertical boundaries with insulated and impermeable horizontal boundaries. To solve the model equations, an implicit finite difference scheme with over relaxation technique has been implemented. The numerical predictions focus specifically on the effect of buoyancy ratio, Lewis number, Darcy number and source-sink arrangements on fluid flow behavior, thermal and solutal characteristics, average Nusselt and Sherwood numbers. The simulations were performed for an extensive range of dimensionless parameters (−10 ≤ N ≤ 10, 0.1 ≤ Le ≤ 1, 10−5 ≤ Da ≤ 10−1) by considering two different types of source-sink arrangements and found that the flow circulation strength is maximum with in-line arrangement of source and sink compared to alternative arrangement. Also, we found that in case-I, regardless of Lewis number, the maximum heat and mass dissipation rates takes place through top source during opposing flow, and through bottom source for aided flow. However, in case-II arrangement, irrespective to type of flow, the greater amount of heat and mass transport is found through the bottom source at the inner cylinder compared to top source placed at outer cylinder.
