Improving an emergency repair process with feature models
Authors: Ignaim Karam , Fernandes João M. 
Published: June 2024

AbstractWhenever an emergency occurs, such as a change in the system operating environment that prevents regular functioning, one possibility to restore the system to normal operation is to perform immediately the emergency repair process (ERP). This paper introduces the feature‐based emergency repair process (FbERP), which constitutes a feature‐based improvement/extension to ERP. FbERP uses feature models to represent urgent change requests (UCRs) and traces each change to its location in the code base in order to realign documentation and code. Based on real‐world change requests, we evaluated the proposed process using different techniques, including an empirical case study and a small survey. In the empirical case study, we compare FbERP with respect to ERP to check the effectiveness, efficiency, and usability of the proposed process. The results of the evaluation reveal that FbERP can be successfully used by software engineers to respond to UCRs, with an improvement over ERP.
Internationalization Through Digital Empowerment for Women Filigree Jewelry Artisan Entrepreneurs in Portugal
Authors: Ratten Vanessa , Braga Vitor 
Published: June 2024

ABSTRACTThe purpose of this study is to examine how Portuguese women jewelry artisan entrepreneurs are empowered using digital technology. Recently, there has been an emphasis on the artisan and craft industry due to renewed interest in handicrafts but limited research exists about how digital and international entrepreneurship has influenced its growth. This study focuses on this gap by stressing the need to take a gender lens on international digital business activity in terms of how it is conducted. In‐depth semistructured interviews with women jewelry makers located in Portugal were conducted to understand how their digital experiences led to increased levels of internationalization. The findings suggest that the use of digital technology was supported by co‐creation, internationalization, and sustainability initiatives. The results of the study highlight the way crisis conditions from the COVID‐19 pandemic led to increased emphasis by artisan entrepreneurs on digital entrepreneurship and this had flow‐on effects leading to higher internationalization rates.

AbstractBackgroundIn June 2021, the first robot‐assisted donor nephrectomy (RADN) was performed at the Leiden University Medical Center (LUMC), the Netherlands. The goal of this study was to investigate whether this procedure has been implemented safely and efficiently.MethodsRADN was retrospectively compared to laparoscopic donor nephrectomy (LDN) performed during the same time period (June 2021 until November 2022). Patients were assigned to RADN depending on the availability of the da Vinci robot and surgical team. The studied endpoints were postoperative complications, operative time, estimated blood loss, warm ischemic time (WIT), and postoperative pain experience. For analysis, the Student's t‐test and Chi‐squared test were used for, respectively, continuous and categorical data.ResultsForty RADN were compared to 63 LDN. Total insufflation time was significantly longer in RADN compared to LDN (188 min (169–214) versus 172 min (144–194); p = 0.02). Additionally, WIT was also found to be significantly higher in the robot‐assisted group (04:54 min vs. 04:07 min; p < 0.01). No statistical differences were found in postoperative outcomes (eGFR of the recipient at 3‐month follow‐up, RADN 54.08 mL/min ±18.79 vs. LDN 56.41 mL/min ±16.82; p = 0.52), pain experience, and complication rate.ConclusionRADN was safely and efficiently implemented at the LUMC. It's results were not inferior to laparoscopic donor nephrectomy. Operative time and warm ischemic times were longer in RADN. This may relate to a learning curve effect. No clinically relevant effect on postoperative outcomes was observed.
Discovery of novel cellobiose lipid gene clusters from Basidiomycetes: How chemical variation is reflected in gene cluster architecture
Authors: Sips Lobke Maria , Lambrecht Laurens , Van Bogaert Inge Noëlle Adrienne 
Published: June 2024

AbstractCellobiose lipids are surface‐active compounds or biological detergents produced by distinct Basidiomycetes yeasts, of which the most and best‐described ones belong to the Ustilaginomycetes class. The molecules display slight variation in congener type, which is linked to the hydroxylation position of the long fatty acid, acetylation profile of the cellobiose unit, and presence or absence of the short fatty acid. In general, this variation is strain specific. Although cellobiose lipid biosynthesis has been described for about 11 yeast species, hitherto only two types of biosynthetic gene clusters are identified, and this for only three species. This work adds six more biosynthetic gene clusters and describes for the first time a novel type of cellobiose lipid biosynthetic cluster with a simplified architecture related to specific cellobiose lipids synthesized by Trichosporonaceae family members.
Distributing Climate Costs Fairly

Published: June 2024

AbstractIn this book, the Netherlands Scientific Council for Government Policy (WRR) considers climate policies in the light of distributive justice. We ask how a society can distribute the costs of climate policy in a way that is fair, and we offer recommendations on how to embed distributive justice in climate policies. This first chapter introduces the problem, defines major concepts and presents the outline of the book.
Distributing the Dutch Reduction Targets
Authors: de Vries Annick , Werner Gijsbert , Wijlhuizen Elsenoor , Toom Victor , Bovens Mark , Hulscher Suzanne 
Published: June 2024

AbstractAllocating the carbon budget is a fundamental issue of distributive justice in global climate policy. At the national level, the carbon budget is often translated into sectoral reduction targets. In this chapter, we ask how the reduction targets should be distributed amongst the industrial, electricity, agriculture and land use, mobility, and built environment sectors. From a perspective of distributive justice, we ask which sectors need to reduce the most carbon emissions if we are to achieve the national targets?
Flood Protection Policies
Authors: de Vries Annick , Werner Gijsbert , Wijlhuizen Elsenoor , Toom Victor , Bovens Mark , Hulscher Suzanne 
Published: June 2024

AbstractFlood protection policy is an existential cause in the Netherlands. It involves the distribution of flood protection measures as well as the distribution of the costs involved. In this chapter, we articulate who benefits from investments in flood protection, and who pays for them. We then consider which distributive principles we can identify in this type of adaptation policy. We explain how other distributive justice considerations and principles could also have been deployed.
Damage After Extreme Rainfall

Published: June 2024

AbstractExtreme weather already causes much damage today, and it will become only more common as climate change progresses, not only in the Netherlands itself but also in the Caribbean territories. In this chapter, we specifically examine the damage caused by extreme rainfall, who is compensated for it, and who actually pays for it. We then consider which distributive principles we can identify in policies. We explain how other distributive justice considerations and principles could also have been deployed.
The constructive method for massive particles in QED
Authors: Lai Hsing-Yi , Liu Da , Terning John 
Published: June 2024

Abstract
The constructive method of determining amplitudes from on-shell pole structure has been shown to be promising for calculating amplitudes in a more efficient way. However, challenges have been encountered when a massless internal photon is involved in the gluing of three-point amplitudes with massive external particles. In this paper, we use the original on-shell method, old-fashioned perturbation theory, to shed light on the constructive method, and show that one can derive the Feynman amplitude by correctly identifying the residue even when there is an internal photon involved.
Manifest color-kinematics duality for point particles interacting with self-dual fields
Authors: Ivanovskiy Vyacheslav , Ponomarev Dmitry 
Published: June 2024

Abstract
We find that point particles interacting with a self-dual Yang-Mills field and self-dual gravity manifestly satisfy color-kinematics duality at the level of action. In a similar way color-kinematics duality also holds for a scalar field minimally coupled to a self-dual Yang-Mills field and self-dual gravity. By applying the appropriate limiting procedure to these scalar field theories we reproduce point particle theories we started from. This allows us to connect worldline color-kinematics duality to amplitude color-kinematics duality in field theory. Considering that point particles act as sources of classical solutions, our results may be regarded as a step towards establishing a precise relation between the amplitude and the classical double copies in the self-dual sector. Finally, we briefly mention that the extension of this discussion to the higher-spin case suggests that scalar point particles cannot interact with chiral higher-spin fields.
Probing ultralight isospin-violating mediators at GW170817
Authors: Liu Zuowei , Tang Zi-Wei 
Published: June 2024

Abstract
Gravitational wave (GW) signals arising from binary neutron star mergers offer new, sensitive probes to ultralight mediators. Here we analyze the GW signals in the GW170817 event detected by the LIGO/Virgo collaboration to impose constraints on the ultralight isospin-violating mediator that has different couplings to protons and neutrons. Neutron stars, which primarily consist of neutrons, are the ideal places to probe the isospin-violating mediator. Such a mediator can significantly alter the dynamics of the binary neutron star mergers, through both the long-range Yukawa force and the new dipole radiation. We compute the gravitational waveform by taking into account the new physics effects due to the isospin-violating mediator and use the Bayesian inference to analyze the gravitational wave data in the GW170817 event. We find that although the current fifth force experiments (including MICROSCOPE and EW) often provide more stringent constraints than the GW170817 data, in the parameter space where the isospin-violating force is completely screened by the Earth (namely, the Earth is charge neutral under this force), the GW170817 data offer the leading constraints: the upper bound on the neutron coupling is fn ≲ 10−19 in the mediator mass range of ≃ (3 × 10−16, 5 × 10−14) eV.
A precise electron EDM constraint on CP-odd heavy-quark Yukawas
Authors: Brod Joachim , Polonsky Zachary , Stamou Emmanuel 
Published: June 2024

Abstract
CP-odd Higgs couplings to bottom and charm quarks arise in many extensions of the standard model and are of potential interest for electroweak baryogenesis. These couplings induce a contribution to the electron EDM. The experimental limit on the latter then leads to a strong bound on the CP-odd Higgs couplings. We point out that this bound receives large QCD corrections, even though it arises from a leptonic observable. We calculate the contribution of CP-odd Higgs couplings to the bottom and charm quarks in renormalisation-group improved perturbation theory at next-to-leading order in the strong interaction, thereby reducing the uncertainty to a few percent.
Coloured spin-1 states in composite Higgs models
Authors: Cacciapaglia Giacomo , Deandrea Aldo , Kunkel Manuel , Porod Werner 
Published: June 2024

Abstract
Strong dynamics for composite Higgs models predict spin-1 resonances which are expected to be in the same mass range as the usually considered top-partners. We study here QCD-coloured vector and axial-vector states stemming from composite Higgs dynamics in several relevant models based on an underlying gauge-fermion description. These states can come as triplet, sextet and octet representation. All models considered have a colour octet vector state in common which can be singly produced at hadron colliders as it mixes with the gluon. We explore the rich and testable phenomenology of these coloured spin-1 states at the LHC and future colliders.
A hyperbolic Kac-Moody Calogero model
Authors: Lechtenfeld Olaf , Zagier Don 
Published: June 2024

Abstract
A new kind of quantum Calogero model is proposed, based on a hyperbolic Kac-Moody algebra. We formulate nonrelativistic quantum mechanics on the Minkowskian root space of the simplest rank-3 hyperbolic Lie algebra AE3 with an inverse-square potential given by its real roots and reduce it to the unit future hyperboloid. By stereographic projection this defines a quantum mechanics on the Poincaré disk with a unique potential. Since the Weyl group of AE3 is a ℤ2 extension of the modular group PSL(2,ℤ), the model is naturally formulated on the complex upper half plane, and its potential is a real modular function. We present and illustrate the relevant features of AE3, give some approximations to the potential and rewrite it as an (almost everywhere convergent) Poincaré series. The standard Dunkl operators are constructed and investigated on Minkowski space and on the hyperboloid. In the former case we find that their commutativity is obstructed by rank-2 subgroups of hyperbolic type (the simplest one given by the Fibonacci sequence), casting doubt on the integrability of the model. An appendix with Don Zagier investigates the computability of the potential. We foresee applications to cosmological billards and to quantum chaos.
Electric network and Hirota type 4-simplex maps
Authors: Konstantinou-Rizos S. 
Published: June 2024

Abstract
Bazhanov-Stroganov (4-simplex) maps are set-theoretical solutions to the 4-simplex equation, namely the fourth member of the family of n-simplex equations, which are fundamental equations of mathematical physics. In this paper, we develop a method for constructing Bazhanov-Stroganov maps as extensions of tetrahedron maps which are set-theoretical solutions to the Zamolodchikov tetrahedron (3-simplex) equation. We employ this method to construct birarional Bazhanov-Stroganov maps which boil down to the famous electric network and Hirota tetrahedron maps at a certain limit.
Partition functions for U(1) vectors and phases of scalar QED in AdS
Authors: Kakkar Astha , Sarkar Swarnendu 
Published: June 2024

Abstract
We extend the computation of one-loop partition function in AdSd+1 using the method in [23] and [24] for scalars and fermions to the case of U(1) vectors. This method utilizes the eigenfunctions of the AdS Laplacian for vectors. For finite temperature, the partition function is obtained by generalizing the eigenfunctions so that they are invariant under the quotient group action, which defines the thermal AdS spaces. The results obtained match with those available in the literature. As an application of these results, we then analyze phases of scalar QED theories at one-loop in d = 2, 3. We do this first as functions of AdS radius at zero temperature showing that the results reduce to those in flat space in the large AdS radius limit. Thereafter the phases are studied as a function of the scalar mass and temperature. We also derive effective potentials and study phases of the scalar QED theories with N scalars.
Extended doubled structures of algebroids for gauged double field theory
Authors: Mori Haruka , Sasaki Shin 
Published: June 2024

Abstract
We study an analogue of the Drinfel’d double for algebroids associated with the O(D, D + n) gauged double field theory (DFT). We show that algebroids defined by the twisted C-bracket in the gauged DFT are built out of a direct sum of three (twisted) Lie algebroids. They exhibit a “tripled”, which we call the extended double, rather than the “doubled” structure appearing in (ungauged) DFT. We find that the compatibilities of the extended doubled structure result not only in the strong constraint but also the additional condition in the gauged DFT. We establish a geometrical implementation of these structures in a (2D + n)-dimensional product manifold and examine the relations to the generalized geometry for heterotic string theories and non-Abelian gauge symmetries in DFT.
EEF1B2 regulates bone marrow-derived mesenchymal stem cells bone-fat balance via Wnt/β-catenin signaling

Published: June 2024

AbstractThe pathological advancement of osteoporosis is caused by the uneven development of bone marrow-derived mesenchymal stem cells (BMSCs) in terms of osteogenesis and adipogenesis. While the role of EEF1B2 in intellectual disability and tumorigenesis is well established, its function in the bone-fat switch of BMSCs is still largely unexplored. During the process of osteogenic differentiation, we observed an increase in the expression of EEF1B2, while a decrease in its expression was noted during adipogenesis. Suppression of EEF1B2 hindered the process of osteogenic differentiation and mineralization while promoting adipogenic differentiation. On the contrary, overexpression of EEF1B2 enhanced osteogenesis and strongly inhibited adipogenesis. Furthermore, the excessive expression of EEF1B2 in the tibias has the potential to mitigate bone loss and decrease marrow adiposity in mice with osteoporosis. In terms of mechanism, the suppression of β-catenin activity occurred when EEF1B2 function was suppressed during osteogenesis. Our collective findings indicate that EEF1B2 functions as a regulator, influencing the differentiation of BMSCs and maintaining a balance between bone and fat. Our finding highlights its potential as a therapeutic target for diseases related to bone metabolism.

AbstractSex pheromones play crucial role in mating behavior of moths, involving intricate recognition mechanisms. While insect chemical biology has extensively studied type I pheromones, type II pheromones remain largely unexplored. This study focused on Helicoverpa armigera, a representative species of noctuid moth, aiming to reassess its sex pheromone composition. Our research unveiled two previously unidentified candidate type II sex pheromones—3Z,6Z,9Z-21:H and 3Z,6Z,9Z-23:H—in H. armigera. Furthermore, we identified HarmOR11 as an orphan pheromone receptor of 3Z,6Z,9Z-21:H. Through AlphaFold2 structural prediction, molecular docking, and molecular dynamics simulations, we elucidated the structural basis and key residues governing the sensory nuances of both type I and type II pheromone receptors, particularly HarmOR11 and HarmOR13. This study not only reveals the presence and recognition of candidate type II pheromones in a noctuid moth, but also establishes a comprehensive structural framework for PRs, contributing to the understanding of connections between evolutionary adaptations and the emergence of new pheromone types.

Comprehensive investigations of 2-phenylethanol production by the filamentous fungus Annulohypoxylon stygium
Authors: Tong Qianwen , Yang Lizhi , Zhang Jinxiang , Zhang Yue , Jiang Yuji , Liu Xinrui , Deng Youjin 
Published: June 2024

Abstract
2-Phenylethanol (2-PE) is an aromatic compound with a rose-like fragrance that is widely used in food and other industries. Yeasts have been implicated in the biosynthesis of 2-PE; however, few studies have reported the involvement of filamentous fungi. In this study, 2-PE was detected in Annulohypoxylon stygium mycelia grown in both potato dextrose broth (PDB) and sawdust medium. Among the 27 A. stygium strains investigated in this study, the strain “Jinjiling” (strain S20) showed the highest production of 2-PE. Under optimal culture conditions, the concentration of 2-PE was 2.33 g/L. Each of the key genes in Saccharomyces cerevisiae shikimate and Ehrlich pathways was found to have homologous genes in A. stygium. Upon the addition of L-phenylalanine to the medium, there was an upregulation of all key genes in the Ehrlich pathway of A. stygium, which was consistent with that of S. cerevisiae. A. stygium as an associated fungus provides nutrition for the growth of Tremella fuciformis and most spent composts of T. fuciformis contain pure A. stygium mycelium. Our study on the high-efficiency biosynthesis of 2-PE in A. stygium offers a sustainable solution by utilizing the spent compost of T. fuciformis and provides an alternative option for the production of natural 2-PE.

Key points
• Annulohypoxylon stygium can produce high concentration of 2-phenylethanol.
• The pathways of 2-PE biosynthesis in Annulohypoxylon stygium were analyzed.
• Spent compost of Tremella fuciformis is a potential source for 2-phenylethanol.
CDC48A, an interactor of WOX2, is required for embryonic patterning in Arabidopsis thaliana
Authors: Gong Wen , Bak Deniz Tiambeng , Wendrich Jos R. , Weijers Dolf , Laux Thomas 
Published: June 2024

Abstract
Key message
Interactor of WOX2, CDC48A, is crucial for early embryo patterning and shoot meristem stem cell initiation, but is not required for WOX2 protein turnover or subcellular localization.

Abstract
During Arabidopsis embryo patterning, the WUSCHEL HOMEOBOX 2 (WOX2) transcription factor is a major regulator of protoderm and shoot stem cell initiation. Loss of WOX2 function results in aberrant protodermal cell divisions and, redundantly with its paralogs WOX1, WOX3, and WOX5, compromised shoot meristem formation. To elucidate the molecular basis for WOX2 function, we searched for protein interactors by IP–MS/MS from WOX2-overexpression roots displaying reprogramming toward shoot-like cell fates. Here, we report that WOX2 directly interacts with the type II AAA ATPase molecular chaperone CELL DIVISION CYCLE 48A (CDC48A). We confirmed this interaction with bimolecular fluorescence complementation and co-immunoprecipitation and found that both proteins co-localize in the nucleus. We show that CDC48A loss of function results in protoderm and shoot meristem stem cell initiation defects similar to WOX2 loss of function. We also provide evidence that CDC48A promotes WOX2 activity independently of proteolysis or the regulation of nuclear localization, common mechanisms of CDC48A function in other processes. Our results point to a new role of CDC48A in potentiating WOX2 function during early embryo patterning.
