AbstractWithin the scope of the European Horizon 2020 project ACDC – Artificial Cells with Distributed Cores to Decipher Protein Function, we aim at the development of a chemical compiler governing the three-dimensional arrangement of droplets, which are filled with various chemicals. Neighboring droplets form bilayers with pores which allow chemicals to move from one droplet to its neighbors. With an appropriate three-dimensional configuration of droplets, we can thus enable gradual biochemical reaction schemes for various purposes, e.g., for the production of macromolecules for pharmaceutical purposes. In this paper, we demonstrate with artificial chemistry simulations that the ACDC technology is excellently suitable to maximize the yield of desired reaction products or to minimize the relative output of unwanted side products.

ZusammenfassungDie Wohnungsfrage ist die soziale Frage unserer Zeit, konstatiert Horst Seehofer, Bundesminister des Inneren, für Bau und Heimat und CSU-Mitglied, bereits Anfang Mai 2018. Diese Relevanzzuschreibung von Wohnen ist politischer Konsens (Bündnis 90 Die Grünen – Bundestagsfraktion, 2020; SPD-Fraktionen in den Ländern, im Bund und im EU-Parlament, 2018) und auch im Jahr 2021 aktuell. Mangelnder bezahlbarer Wohnraum ist eine der Hauptursachen von Wohnungsnot und Wohnungslosigkeit.

One-loop algebras and fixed flow trajectories in adjoint multi-scalar gauge theory
Authors: Flodgren Nadia , Sundborg Bo 
Published: April 2023

Abstract
We study the one loop renormalisation of 4d SU(N) Yang-Mills theory with M adjoint representation scalar multiplets related by O(M) symmetry. General M are of field theoretic interest, and the 4d one loop beta function of the gauge coupling g2 vanishes for the case M = 22, which is intriguing for string theory. This case is related to D3 branes of critical bosonic string theory in D = 22 + 4 = 26. An RG fixed point could have provided a definition for a purely bosonic AdS/CFT, but we show that scalar self-couplings λ ruin one-loop conformal invariance in the large N limit. There are real fixed flows (fixed points of λ/g2) only for M ≥ 406, rendering one-loop fixed points of the gauge coupling and scalar couplings incompatible.We develop and check an algebraic approach to the one-loop renormalisation group which we find to be characterised by a non-associative algebra of marginal couplings. In the large N limit, the resulting RG flows typically suffer from strong coupling in both the ultraviolet and the infrared. Only for M ≥ 406 fine-tuned solutions exist which are weakly coupled in the infrared.
A forgotten fermion: the hypercharge −3/2 doublet, its phenomenology and connections to dark matter
Authors: Coy Rupert 
Published: April 2023

Abstract
A weak-doublet with hypercharge −3/2 is one of only a handful of fermions which has a renormalisable interaction with Standard Model fields. This should make it worthy of attention, but it has thus far received little consideration in the literature. In this paper, we perform a thorough investigation of the phenomenology which results from the introduction of this field, F. After expressing the model in terms of its effective field theory at dimension-6, we compute a range of electroweak and leptonic observables, the most stringent of which probe up to MF ~ 300 TeV. The simplicity of this scenario makes it very predictive and allows us to correlate the different processes. We then study how this new fermion can connect the SM to various simple but distinct dark sectors. Some of the most minimal cases of F-mediated dark matter (DM) involve frozen-in keV-scale scalar DM, which may produce x-ray lines, and frozen-out TeV-scale fermionic DM.
A microscopic analogue of the BMS group
Authors: Weiss Daniel Alexander 
Published: April 2023

Abstract
We consider a microscopic analogue of the BMS analysis of asymptotic symmetries by analysing universal geometric structures on infinitesimal tangent light cones. Thereby, two natural microscopic symmetry groups arise: a non-trivially represented Lorentz group and a BMS-like group. The latter has a rich mathematical structure, since it contains the former as a non-canonical subgroup, next to infinitely many other Lorentz subgroups. None of those Lorentz subgroups appears to be intrinsically preferred, and hence, the microscopic BMS-like group constitutes a natural symmetry group for infinitesimal tangent light cones. We compare our investigation with the classical BMS analysis and show, that the microscopic BMS-like group is a gauge group for the bundle of null vectors. Motivated by the various applications of the original BMS group, our findings could have interesting implications: they identify a geometric structure that could be suitable for a bulk analysis of gravitational waves, they suggest a possible enlargement of the fundamental gauge group of gravity and they motivate the possibility of an interrelation between the UV structure of gauge theories, gravitational memory effects and BMS-like symmetries. Also, our results imply, that BMS-like groups arise not only as macroscopic, asymptotic symmetry groups in cosmology, but describe also a fundamental and seemingly unknown microscopic symmetry of pseudo-Riemannian geometry.
One-loop Lipatov vertex in QCD with higher ϵ-accuracy
Authors: Fadin Victor S. , Fucilla Michael , Papa Alessandro 
Published: April 2023

Abstract
The effective Reggeon-Reggeon-gluon vertex, known as Lipatov vertex, is the key ingredient that allows to develop the BFKL approach in QCD. Within the next-to-leading logarithmic approximation, it is sufficient to know its one-loop corrections, in dimensional regularization (D = 4 + 2ϵ), up to the constant term in the ϵ-expansion. In the next-to-next-to-leading approximation, however, the one-loop Lipatov vertex is needed up to the order ϵ2. In this paper we present the expression for this vertex in dimensional regularization up to the required accuracy.
Infrared-safe flavoured anti-kT jets
Authors: Czakon Michal , Mitov Alexander , Poncelet Rene 
Published: April 2023

Abstract
Flavour tagging is technically challenging on the experimental side. However, it suffers from a more fundamental problem from the theoretical point of view, in particular when implemented in fixed-order perturbation theory. It turns out that an infrared-safe definition of a flavoured jet is intricate due to the singularities induced by the emission of flavoured quark-anti-quark pairs of negligible energy. Although this issue has been addressed by a modification of the standard kT jet algorithm, the situation is not entirely satisfactory as most measurements rather use the anti-kT jet algorithm. In this work, we propose a flavour-aware infrared-safe modification of the anti-kT jet algorithm that is easy to implement within perturbative Monte Carlo frameworks and has minor impact on jet phenomenology when flavour tagging is not required. Besides the numerical verification of the infrared safety of the proposed algorithm at next-to-next-to-leading order, we also present results for the hadro-production of a lepton pair in association with a b-jet, and of a top-quark pair decaying into b-jets and leptons.
Identifying quenched jets in heavy ion collisions with machine learning
Authors: Liu Lihan , Velkovska Julia , Wu Yilun , Verweij Marta 
Published: April 2023

Abstract
Measurements of jet substructure in ultra-relativistic heavy ion collisions suggest that the jet showering process is modified by the interaction with the quark-gluon plasma. Modifications of the hard substructure of jets can be explored with modern data-driven techniques. In this study, a machine learning approach to the identification of quenched jets is designed. Jet showering processes are simulated with a jet quenching model Jewel and a non-quenching model Pythia 8. Sequential substructure variables are extracted from the jet clustering history following an angular-ordered sequence and are used in the training of a neural network built on top of a long short-term memory network. We show that this approach successfully identifies the quenching effect in the presence of the large uncorrelated background of soft particles created in heavy-ion collisions.
Entanglement entropy in internal spaces and Ryu-Takayanagi surfaces

Published: April 2023

Abstract
We study minimum area surfaces associated with a region, R, of an internal space. For example, for a warped product involving an asymptotically AdS space and an internal space K, the region R lies in K and the surface ends on ∂R. We find that the result of Graham and Karch can be avoided in the presence of warping, and such surfaces can sometimes exist for a general region R. When such a warped product geometry arises in the IR from a higher dimensional asymptotic AdS, we argue that the area of the surface can be related to the entropy arising from entanglement of internal degrees of freedom of the boundary theory. We study several examples, including warped or direct products involving AdS2, or higher dimensional AdS spaces, with the internal space, K = Rm, Sm; Dp brane geometries and their near horizon limits; and several geometries with a UV cut-off. We find that such RT surfaces often exist and can be useful probes of the system, revealing information about finite length correlations, thermodynamics and entanglement. We also make some preliminary observations about the role such surfaces can play in bulk reconstruction, and their relation to subalgebras of observables in the boundary theory.
Virasoro blocks and the reparametrization formalism
Authors: Nguyen Kevin 
Published: April 2023

Abstract
An effective theory designed to compute Virasoro identity blocks at large central charge, expressed in terms of the propagation of a reparametrization/shadow mode between bilocal vertices, was recently put forward. In this paper I provide the formal theoretical framework underlying this effective theory by reformulating it in terms of standard concepts: conformal geometry, generating functionals and Feynman diagrams. A key ingredient to this formalism is the bilocal vertex operator, or reparametrized two-point function, which is shown to generate arbitrary stress tensor insertions into a two-point function of reference. I also suggest an extension of the formalism designed to compute generic Virasoro blocks.

Published: April 2023

Abstract
We consider QCD radiative corrections to the production of a heavy-quark pair in hadronic collisions. We present the computation of the soft-parton contributions at low transverse momentum of the heavy-quark pair up to second order in the QCD coupling αS. These results complete the evaluation at the next-to-next-to-leading order (NNLO) of the transverse-momentum resummation formula for this process. Moreover, they give all the ingredients that are needed for the NNLO implementation of the qT subtraction formalism for heavy-quark production. We discuss the details of the computation and we provide a code that can be used to obtain the relevant results in numerical form.

AbstractThe German National Reference Centre for Authentic Food (NRZ-Authent) and the competent German food control authorities of the federal states cooperated within the framework of the 10th joint Europol INTERPOL operation OPSON (OPSON X) in the detection of adulterated meat products. A total of 63 meat product samples were collected and analysed by the authorities using standard analytical procedures and subjected to a recently published 16S rDNA metabarcoding analysis. The sequence reads were analysed using 3 bioinformatics data processing strategies. The study aimed to gain additional data on the test samples regarding the authenticity of the declared species and to validate the 16S rDNA metabarcoding method with representative samples. The method was tested not only on 63 test samples, but also on 5 commercial samples from 2 interlaboratory comparison studies and 9 mock mixtures in parallel. The 16S rDNA metabarcoding method was able to detect species that were not target species of the used standard analytical methods, but failed, as shown previously, to detect fallow deer. Otherwise, the qualitative results of the 16S rDNA metabarcoding method were very similar to those of the methods currently in use by the German food control laboratories. Thus, the method has great potential to be used as a screening method for the authentication of mammal and poultry species in meat products.
Operative Therapie von Nävi bei Kindern in einem dermatochirurgischen Zentrum

Published: April 2023

Zusammenfassung
Hintergrund
Im Kindesalter ist die Indikationsstellung zur operativen Therapie und histologischen Diagnostik bei melanozytären Nävi eine große Herausforderung im klinischen Alltag. In der Beratung der Kinder und Eltern nimmt auf der einen Seite der Ausschluss von malignen Befunden, auf der anderen Seite das Risiko für Komplikationen die größte Rolle ein.

Patienten und Methodik
Es wurden 946 Kinder unter 10 Jahren eingeschlossen, die mit der Verdachtsdiagnose eines Melanozytennävus an der Universitätshautklinik Tübingen zwischen 2008 und 2018 operiert wurden. Erfasst wurden der dermatohistopathologische Befund sowie postoperative Komplikationen.

Ergebnisse
Die klinische Diagnose eines melanozytären Nävus wurde in 93,2 % (882/946) der Fälle histologisch bestätigt. Darunter fanden sich 41 Spitz-Nävi und 18 pigmentierte Spindelzelltumoren. Bei 2 Kindern (0,2 %) aus dem Kollektiv wurde die Diagnose eines Melanoms gestellt. Bei weiteren 6,6 % fanden sich nichtmelanozytäre Befunde (u. a. Naevus sebaceus, epidermale Nävi). Die Komplikationsrate war mit 3 % gering. Die häufigste Komplikation war in 1,7 % das Auftreten eines postoperativen Wundinfektes.

Schlussfolgerung
Es ist auch im Kleinkindesalter möglich, kongenitale Nävi unterschiedlicher Größe zu biopsieren oder operativ zu entfernen. Ein wichtiges Instrument hierfür ist die serielle Exzision kongenitaler Nävi. Im untersuchten Kollektiv zeigte sich eine geringe Komplikationsrate. Eine histologische Sicherung ist bei klinisch suspekten oder untypischen Befunden unabdingbar.

Abstract
Introduction and hypothesis
The objective was to compare the location and motion of pessaries between women with pelvic organ prolapse (POP) with a successful (fitting) and unsuccessful (non-fitting) pessary treatment on dynamic magnetic resonance imaging (dMRI).

Methods
A cross-sectional exploratory study of 15 women who underwent a mid-sagittal dMRI of the pelvic floor at rest, during contraction and during Valsalva with three different types of pessaries. The coordinates of the pessaries cross section, inferior pubic point (IPP) and sacrococcygeal junction (SCJ) were obtained and the location (position, orientation) and the motion (translation and rotation) were calculated. Differences between the groups and between the pessaries within the groups were compared.

Results
Nine women with a fitting pessary and 6 women with a non-fitting pessary were selected. In the non-fitting group, the pessaries were positioned more caudally and rotated more in clockwise direction and descended more, but not significantly, during Valsalva compared with the fitting group. The Falk pessary was positioned more anteriorly in the fitting group and more cranially in the non-fitting group compared with the ring and ring with support pessary.

Conclusions
A non-fitting pessary was positioned more caudally at rest; on Valsalva, it rotated more clockwise and moved more caudally, suggesting that the dynamic characteristics of the pessary might play an important role in its effectiveness. Findings of this study serve as a basis for the development of new pessary designs.
The impact of corporate sustainability performance on advertising efficiency
Authors: Weinmayer Karl , Garaus Marion , Wagner Udo 
Published: April 2023

AbstractOver the years several studies have reported a significant waste of advertising budget, a finding which calls for strategies to increase advertising efficiency. While some factors, such as brand extensions or an optimal marketing mix, have already been identified as relevant determinants of advertising efficiency, changes in consumer psychographics have so far been neglected. The current study fills this gap by investigating how the emerging awareness and demand for corporate sustainability serve as a contextual factor leveraging or hindering advertising efficiency. Furthermore, we investigate how advertising efficiency has changed across various industry sectors from 2010 to 2019. A two-step procedure was applied to analyze the secondary data of 1950 observations from 195 US firms in five industry sectors over a period of 10 years. The resulting time series of firm-specific multi-directional efficiency scores confirms that advertising efficiency varies over time, justifying the relevance of a dynamic perspective for analyzing advertising efficiency. Furthermore, in support of our main claim, the investigation of the relationship between advertising efficiency and the environmental, social and governance performance of firms over time using a time-fixed effects panel regression and a three-level hierarchical regression model confirm the significant impact of corporate sustainability performance on advertising efficiency. Interestingly, this effect varies among different industry sectors and not all corporate sustainability activities impact advertising efficiency to the same extent. The results not only emphasize the relevance of corporate sustainability performance in increasing advertising efficiency, but also guide marketers on strategic marketing decisions related to the allocation of advertising budget.
The antifungal effect induced by itraconazole in Candida parapsilosis largely depends on the oxidative stress generated at the mitochondria

AbstractIn Candida parapsilosis, homozygous disruption of the two genes encoding trehalase activity increased the susceptibility to Itraconazole compared with the isogenic parental strain. The fungicidal effect of this azole can largely be counteracted by preincubating growing cells with rotenone and the protonophore 2,4-Dinitrophenol. In turn, measurement of endogenous reactive oxygen species formation by flow cytometry confirmed that Itraconazole clearly induced an internal oxidative stress, which can be significantly abolished in rotenone-exposed cells. Analysis of the antioxidant enzymatic activities of catalase and superoxide dismutase pointed to a moderate decrease of catalase in trehalase-deficient mutant cells compared to the wild type, with an additional increase upon addition of rotenone. These enzymatic changes were imperceptible in the case of superoxide dismutase. Alternative assays with Voriconazole led to a similar profile in the results regarding cell growth and antioxidant activities. Collectively, our data suggest that the antifungal action of Itraconazole on C. parapsilosis is dependent on a functional mitochondrial activity. They also suggest that the central metabolic pathways in pathogenic fungi should be considered as preferential antifungal targets in new research.
