Why Be Euphorically Queer? An Ecological Model of Euphorias’ Influences & Impacts
Authors: Jones Tiffany 
Published: February 2023

AbstractExpanding on psychological and individualist frames emphasising transgender and gender diverse (TGD) experiences; this chapter supplies a new ecological model of potential influences on the development of euphorias to assist in service applications, everyday lives, and lesbian, gay, bisexual, transgender, intersex, and queer (LGBTIQ+) research. The model adds culturally embedded psycho-social accounts of affect and development from Bronfenbrenner, Erikson, Ahmed, and Butler. It shows euphorias as potentially influenced by what is privileged in individuals’ developmental stages and systems of social and institutional engagements, policy contexts, and cultural norms over time. The chapter argues for being euphorically queer—using erasure, overplay, and transference of happiness onto non-traditional identities and bodies, towards energising responsiveness to LGBTIQ+ and other othered groups’ needs, and against conforming contentedness which stagnates activisms.
Properties of the conformal Yangian in scalar and gauge field theories
Authors: Dokmetzoglou Nikolaos , Dolan Louise 
Published: February 2023

Abstract
Properties of the SO(2, n) Yangian acting on scalar and gauge fields are presented. This differential operator representation of the infinite-dimensional extension of the conformal algebra SO(2, n) is proved to satisfy the Serre relation for arbitrary spacetime dimension n for off-shell scalar theory, but only on shell and for n = 4 in the gauge theory. The SO(2, n) Yangian acts simply on the off-shell kinematic invariants (kI + kI+1 + …)2, and it annihilates individual off-shell scalar λϕ3 Feynman tree graphs for n = 6 if the differential operator representation is extended by graph dependent evaluation terms. The SO(2, 4) Yangian level one generators are shown to act in a compact way on pure Yang- Mills gluon tree amplitudes. The action of the Yangian on the scattering polynomials of a CHY formalism is also described.
The cost of an ALP solution to the neutral B-anomalies
Authors: Bonilla J. , de Giorgi A. , Gavela B. , Merlo L. , Ramos M. 
Published: February 2023

Abstract
The neutral anomalies in B decays are analysed in terms of the tree-level exchange of an axion-like-particle (ALP), within the effective field theory framework. The complete two-dimensional parameter space for ALP couplings to electrons and muons is explored. The solutions to RK and to the two energy bins of $$ {R}_{K^{\ast }} $$

are confronted with the impact of ALP exchange on other observables (meson oscillations, leptonic and semileptonic decays of B mesons including searches for new resonances, astrophysical constraints), as well as with the theoretical domain of validity of the effective theory. Solutions based on ALPs heavier than B mesons, or lighter than twice the muon mass, are shown to be excluded. In contrast, the exchange of on-shell ALPs provides solutions to RK and/or $$ {R}_{K^{\ast }} $$

The impact of smearing on data analysis is also discussed. When loop effects are taken into account, the solutions found can be in addition compatible with the data on the g − 2 of the electron but not simultaneously with those on the g − 2 of the muon. Furthermore, loop effects may require fine-tunings of some coupling values.
Littlest modular seesaw
Authors: de Medeiros Varzielas Ivo , King Steve F. , Levy Miguel 
Published: February 2023

Abstract
We present the first complete model of the Littlest Modular Seesaw, based on two right-handed neutrinos, within the framework of multiple modular symmetries, justifying the use of multiple moduli fields which take their values at 3 specific stabilizers of Γ4 ≃ S4, including a new phenomenological possibility. Using a semi-analytical approach, we perform a χ2 analysis of each case and show that good agreement with neutrino oscillation data is obtained, including predictive relations between the leptonic mixing angles and the ratio of light neutrino masses, which non-trivially agree with the experimental values. It is noteworthy that in this very predictive setup, the models fit the global fits of the experimental data remarkably well, both with and without the Super-Kamiokande atmospheric data, for both models presented here. By extending the model to include a weighton and the double cover group $$ {\Gamma}_4^{\prime}\simeq {S}_4^{\prime } $$

Engineering small flux superpotentials and mass hierarchies
Authors: Bastian Brice , Grimm Thomas W. , van de Heisteeg Damian 
Published: February 2023

Abstract
We study the stabilization of complex structure moduli in Type IIB flux compactifications by using recent general results about the form of the superpotential and Kähler potential near the boundaries of the moduli space. In this process we show how vacua with an exponentially small vacuum superpotential can be realized systematically and understood conceptually within asymptotic Hodge theory. We distinguish two types of vacua realizing such superpotentials that differ by the mass scales of the stabilized moduli. Masses polynomially depending on the moduli arise if the superpotential contains exponential corrections whose existence is required to ensure the non-degeneracy of the moduli space metric. We use the fact that such essential corrections are controlled by asymptotic Hodge theory and have recently been constructed for all one- and two-moduli asymptotic regimes. These insights allow us to obtain new vacua near boundaries in complex structure moduli space that include Seiberg-Witten points. In these examples we find that the scale of the vacuum superpotential can be bounded from below through the exponential of the negative D3-brane tadpole.
Towards the non-perturbative cosmological bootstrap
Authors: Hogervorst Matthijs , Penedones Joao , Vaziri Kamran Salehi 
Published: February 2023

Abstract
We study quantum field theory on a de Sitter spacetime dSd+1 background. Our main tool is the Hilbert space decomposition in irreducible unitary representations of its isometry group SO(d + 1, 1). As the first application of the Hilbert space formalism, we recover the Källen-Lehmann spectral decomposition of the scalar bulk two-point function. In the process, we exhibit a relation between poles in the corresponding spectral densities and the boundary CFT data. Moreover, we derive an inversion formula for the spectral density through analytical continuation from the sphere and use it to find the spectral decompisiton for a few examples. Next, we study the conformal partial wave decomposition of the four-point functions of boundary operators. These correlation functions are very similar to the ones of standard conformal field theory, but have different positivity proper- ties that follow from unitarity in de Sitter. We conclude by proposing a non-perturbative conformal bootstrap approach to the study of these late-time four-point functions, and we illustrate our proposal with a concrete example for QFT in dS2.
On triality defects in 2d CFT
Authors: Lu Da-Chuan , Sun Zhengdi 
Published: February 2023

Abstract
We consider the triality fusion category discovered in the c = 1 Kosterlitz-Thouless theory [1]. We analyze this fusion category using the tools from the group theoretical fusion category and compute the simple lines, fusion rules and F-symbols. We then studied the physical implication of this fusion category including deriving the spin selection rule, computing the asymptotic density of states of irreducible representations of the fusion category symmetries, and analyzing its anomaly and constraints under the renormalization group flow. There is another set of F-symbols for the fusion categories with the same fusion rule known in the literature [2]. We find these two solutions are different as they lead to different spin selection rules. This gives a complete list of the fusion categories with the same fusion rule by the classification result in [3].
Improved error estimates for the finite volume and the MAC schemes for the compressible Navier–Stokes system
Authors: Feireisl Eduard , Lukáčová-Medvid’ová Mária , She Bangwei 
Published: February 2023

AbstractWe present new error estimates for the finite volume and finite difference methods applied to the compressible Navier–Stokes equations. The main innovative ingredients of the improved error estimates are a refined consistency analysis combined with a continuous version of the relative energy inequality. Consequently, we obtain better convergence rates than those available in the literature so far. Moreover, the error estimates hold in the whole physically relevant range of the adiabatic coefficient.

Authors: Ecsedi István , Baksa Attila 
Published: February 2023

AbstractThe Saint-Venant torsion of cylindrical orthotropic homogeneous linearly elastic bar is considered. The cross section of the bar is bounded by two straight lines and a curved arc. The geometry of the boundary curve of cross section depends on the shear moduli of the cylindrical orthotropic bar. An analytical method is presented to obtain the Prandtl’s stress functions, warping function, shearing stresses and the torsional rigidity.

AbstractRising incidence and mortality of cancer have led to an incremental amount of research in the field. To learn from preexisting data, it has become important to capture maximum information related to disease type, stage, treatment, and outcomes. Medical imaging reports are rich in this kind of information but are only present as free text. The extraction of information from such unstructured text reports is labor-intensive. The use of Natural Language Processing (NLP) tools to extract information from radiology reports can make it less time-consuming as well as more effective. In this study, we have developed and compared different models for the classification of lung carcinoma reports using clinical concepts. This study was approved by the institutional ethics committee as a retrospective study with a waiver of informed consent. A clinical concept-based classification pipeline for lung carcinoma radiology reports was developed using rule-based as well as machine learning models and compared. The machine learning models used were XGBoost and two more deep learning model architectures with bidirectional long short-term neural networks. A corpus consisting of 1700 radiology reports including computed tomography (CT) and positron emission tomography/computed tomography (PET/CT) reports were used for development and testing. Five hundred one radiology reports from MIMIC-III Clinical Database version 1.4 was used for external validation. The pipeline achieved an overall F1 score of 0.94 on the internal set and 0.74 on external validation with the rule-based algorithm using expert input giving the best performance. Among the machine learning models, the Bi-LSTM_dropout model performed better than the ML model using XGBoost and the Bi-LSTM_simple model on internal set, whereas on external validation, the Bi-LSTM_simple model performed relatively better than other 2. This pipeline can be used for clinical concept-based classification of radiology reports related to lung carcinoma from a huge corpus and also for automated annotation of these reports.
Electric micromobility from a policy-making perspective through European use cases
Authors: Aba Attila , Esztergár-Kiss Domokos 
Published: February 2023

AbstractEuropean urban areas have different practices for the planning of transportation systems, for the decision-making processes of new regulations, the implementation of transportation solutions, and for the cooperation between operators. In this paper, the specific conditions and potential solutions in the field of electric micromobility (e-micromobility) are analyzed. The elaborated method consists of two parts. In the first part, an expert workshop is conducted, where urban mobility experts from different fields share their experience of e-micromobility and its relevance to policy-making. Additionally, an expert survey is developed to set an urban definition of e-micromobility up and to bring its most relevant parameters into focus. In the second part, a framework assessment including planning, regulatory, and practical realizations related to the usage of new mobility services is created. The findings can serve as an input to recommendations, roadmaps, implementation guidelines, and policy documents for urban planners and decision-makers.

Published: February 2023

AbstractWe have developed a new method to measure the viscosity of micrometric films by thermomechanical analysis with a hemispherical probe of millimetric diameter. The loading curve (displacement vs. time) recorded as the probe tip crosses the whole film at constant load until it touches the substrate is fitted to a theoretical curve shape that has been obtained after solving the problem of liquid flow under the probe tip. The method has been validated by measuring the viscosity of rosin films. It has been applied to analyze the thermal evolution of unstable liquid films that appear on Ba propionate, Ce(III) propionate and a low-fluorine precursor film of YBa2Cu3O6+x. During pyrolysis of the last two films, viscosity first diminishes due to heating and then it increases as solid oxide particles are formed inside the liquid.

Published: February 2023

AbstractModern High Level Synthesis (HLS) tools succeed well in their engineering productivity goal, but still require toolset and target technology specific modifications to the source code to guide the process towards an efficient implementation. Furthermore, their end result is a fixed function accelerator with limited field and runtime flexibility. In this paper we describe the status of AEx, a novel work-in-progress HLS tool developed in the FitOptiVis ECSEL JU project. AEx is based on automated exploration of architectures using a flexible and lightweight parallel co-processor template. We compare its current performance in CHStone C-language benchmarks to the state of the art FPGA HLS tool Vitis, provide ASIC implementation numbers, and identify the main remaining toolset features that are expected to dramatically further improve the performance. The potential is explored with a hand-optimized case study that shows only 1.64x performance slowdown with the programmable co-processor in comparison to the fixed function Vitis HLS result.
Enhanced MOKE Via Tunable Plasmon Resonance Field in the Otto Configuration
Authors: Patiño Edgar J. , Quiroga S. Leidy Paola , Herreño-Fierro César A. 
Published: February 2023

AbstractHere, we demonstrate the enhancement of the transverse magneto-optical Kerr effect (TMOKE) signal, due to surface plasmon resonance in the Otto configuration, where the low index dielectric has a variable thickness. This constitutes a demonstration that, in principle, a separation of the magnetic sample from the plasmonic device and the modulation of the plasmon resonance with an enhancement of the MOKE signal is possible. We have achieved this by using air as a low index dielectric where the evanescent wave extends, preceding to excitation of surface plasmons. The magnetic sample under consideration is a thin layer of cobalt coated by an ultrathin silver layer, on a silicon substrate (Ag/Co/Si). The sample is brought close enough to the prism/air interface, allowing surface plasmon excitation in the air/Ag interface. This leads to an increase of the TMOKE signal up to ~ 2 ‰ with respect to the incident light. This is about 7 times the traditional MOKE signal in the absence of plasmons. This is comparable with previous works using the Kretschmann-Raether configuration. Furthermore, the fact that the plasmon field generated at the metal-air interface substitutes the laser light used in traditional MOKE allows new functionalities such as controlling the penetration depth of the plasmonic field into the sample. This should find applications in magnetometry and related technology.

AbstractThe results of electrical and photoelectrical characterization of the interface and bulk properties of n+-ZnO/n-Si and poly(3,4-ethylene dioxythiophene):poly(styrenesulfonate) (PEDOT:PSS)/n+-ZnO/n-Si heterostructures are presented. It was found that the PEDOT:PSS layer deposited on the surface of zinc oxide increases the potential barrier at the ZnO/Si interface, leading to higher band bending in the silicon, which is important for solar cell applications. The recombination rate at the interface decreases because of the creation of an inversion layer in the silicon under operational conditions. The increase of the potential barrier in PEDOT:PSS/n+-ZnO/n-Si heterostructures results in the increase of the open-circuit voltage by 54–180%. The external quantum efficiency in PEDOT:PSS/n+-ZnO/n-Si heterostructures increases by 100% at 450 nm.

AbstractObjectiveTo observe the clinical efficacy of herbal cake-partitioned moxibustion for ulcerative colitis (UC) and elucidate its mechanism by targeting the vitamin D receptor (VDR) signaling pathway.MethodsA total of 63 patients with UC were randomly divided into an observation group (30 cases, treated with herbal cake-partitioned moxibustion) and a control group (33 cases, treated with sham herbal cake-partitioned moxibustion). Moxibustion treatment was performed at Qihai (CV6) and bilateral Tianshu (ST25) and Shangjuxu (ST37), 3 times per week for 12 weeks. The total effective rate, visual analog scale (VAS) score for abdominal bloating and pain, and hospital anxiety and depression scale (HADS) score were compared between the two groups. Enzyme-linked immunosorbent assay was used to detect the concentrations of serum C-reactive protein (CRP), 25-hydroxyvitamin D [25(OH)D], and interleukin-12 (IL-12)/interleukin-23 (IL-23) p40. Immunohistochemistry was used to observe the expression levels of VDR and regenerating gene IV (Reg IV) proteins in colonic mucosa. The expression levels of VDR, cytochrome p450 27B1 (CYP27B1), and Reg IV mRNAs were detected by real-time fluorescence quantitive polymerase chain reaction.ResultsAfter treatment, the total effective rate in the observation group was 86.7%, which was significantly higher than 51.5% in the control group (P<0.05). After treatment, the VAS scores for abdominal bloating and pain in the observation group were significantly decreased (P<0.01), as well as the HADS-depression subscale (HADS-D) and HADS-anxiety subscale (HADS) scores (P<0.05), while only the VAS score for abdominal pain in the control group was reduced (P<0.05), and the improvements of the scores in the observation group were more significant than those in the control group (P<0.05). After treatment, the serum CRP concentrations in both groups and the IL-12/IL-23 p40 concentration in the observation group were significantly decreased (P<0.05), and the concentrations in the observation group were lower than those in the control group (P<0.05). The expression levels of VDR protein and mRNA in the colon in both groups were all increased (P<0.01), and the expression levels of Reg IV protein and mRNA and CYP27B1 mRNA were all decreased in the two groups (P<0.05 orP<0.01); the improvements in the observation group were more notable than those in the control group (P<0.05 orP<0.01).ConclusionHerbal cake-partitioned moxibustion can effectively alleviate abdominal pain and diarrhea in patients with UC, improve depression and anxiety disorders, and regulate the expression of related proteins in the VDR signaling pathway. The mechanism may be related to inhibiting intestinal inflammation by reducing the release of the proinflammatory cytokine IL-12/IL-23 p40.
Transformative social innovation in developing and emerging ecosystems: a configurational examination
Authors: Cortese Damiano , Civera Chiara , Casalegno Cecilia , Zardini Alessandro 
Published: February 2023

AbstractDespite the literature on social innovation (SI) in ecosystems growing considerably in recent years, what makes an ecosystem a facilitator for transformative SI remains unexamined, particularly indeveloping and emerging countries. Our research aims to fill this literature gap by determining which combination of characteristics—stemming from stakeholder theory and knowledge management–turns local smallholder coffee farmers in developing and emerging producing countries into autonomous and empowered partners and catalysts for spreading SI initiatives locally. We adopt a configurational approach using fuzzy-set qualitative comparative analysis of 18 SI projects that coffee MNEs, nongovernmental organizations, and institutions have undertaken to favor such an egalitarian value co-creation with local stakeholders. We demonstrate that stakeholder empowerment, cooperative strategic posturing, knowledge transfer, and local knowledge exchange are necessary conditions within the ecosystem to create local autonomy as an antecedent for transformative SI. The novelty in our approach lies in proposing a shift from a pure firm-centric perspective based on stakeholder dependence to a more participatory relational perspective that entails lower-power stakeholders’ interdependence and collaboration for autonomous decision-making, thereby advancing fresh thinking on stakeholder and knowledge management applied to SI in developing and emerging contexts. We also propose practical suggestions to deal with stakeholder power’s imbalances, which might limit the ecosystems’ adaptation toward transformative SI.
