Exploring confinement in Anti-de Sitter space
Authors: Ciccone Riccardo , De Cesare Fabiana , Di Pietro Lorenzo , Serone Marco 
Published: January 2025

Abstract
We study Yang-Mills theory on four dimensional Anti-de Sitter space. The Dirichlet boundary condition cannot exist at arbitrarily large radius because it would give rise to colored asymptotic states in flat space. As observed in [1] this implies a deconfinement-confinement transition as the radius is increased. We gather hints on the nature of this transition using perturbation theory. We compute the anomalous dimensions of the lightest scalar operators in the boundary theory, which are negative for the singlet and positive for non-trivial representations. We also compute the correction to the coefficient CJ and we estimate that the singlet operator reaches marginality before the value of the coupling at which CJ = 0. These results favor the scenario of merger and annihilation as the most promising candidate for the transition. For the Neumann boundary condition, the lightest scalar operator is found to have a positive anomalous dimension, in agreement with the idea that this boundary condition extrapolates smoothly to flat space. The perturbative calculations are made possible by a drastic simplification of the gauge field propagator in Fried-Yennie gauge. We also derive a general result for the leading-order anomalous dimension of the displacement operator for a generic perturbation in Anti-de Sitter, showing that it is related to the beta function of bulk couplings.
SPECTER: efficient evaluation of the spectral EMD
Authors: Gambhir Rikab , Larkoski Andrew J. , Thaler Jesse 
Published: January 2025

Abstract
The Energy Mover’s Distance (EMD) has seen use in collider physics as a metric between events and as a geometric method of defining infrared and collinear safe observables. Recently, the Spectral Energy Mover’s Distance (SEMD) has been proposed as a more analytically tractable alternative to the EMD. In this work, we obtain a closed-form expression for the Riemannian-like p = 2 SEMD metric between events, eliminating the need to numerically solve an optimal transport problem. Additionally, we show how the SEMD can be used to define event and jet shape observables by minimizing the distance between events and parameterized energy flows (similar to the EMD), and we obtain closed-form expressions for several of these observables. We also present the Specter framework, an efficient and highly parallelized implementation of the SEMD metric and SEMD-derived shape observables as an analogue of the previously-introduced Shaper for EMD-based computations. We demonstrate that computing the SEMD with Specter can be up to a thousand times faster than computing the EMD with standard optimal transport libraries.
Two-loop running effects in Higgs physics in Standard Model Effective Field Theory
Authors: Di Noi Stefano , Gröber Ramona , Mandal Manoj K. 
Published: January 2025

Abstract
We consider the renormalization group equations within the Standard Model Effective Field Theory and compute two-loop contributions proportional to the top quark Yukawa coupling for the operator generating an effective Higgs-gluon coupling, focusing on the Yukawa-like operator. These two-loop running effects are relevant for processes where the effective Higgs-gluon coupling contributes at a lower loop order compared to the Standard Model contribution and where a dynamical scale choice is adopted. Such a situation arises, for instance, in the Higgs transverse momentum distribution and Higgs pair production. We investigate the phenomenological impact of our computations on these two processes and find that the two-loop contributions are significant and can lead to deviations of up to 20% in the scenarios we consider.
Tidal Love numbers of static black holes in anti-de Sitter
Authors: Franzin Edgardo , Frassino Antonia M. , Rocha Jorge V. 
Published: January 2025

Abstract
Tidal Love numbers of anti-de Sitter black holes are understood as linear response coefficients governing how the holographically dual plasma polarizes when the geometry of the space, in which the plasma lives, is deformed. So far, this picture has been applied only to black branes with plane wave perturbations. We fill the gap in the literature by performing the computation of tidal Love numbers for the four-dimensional Schwarzschild solution in global anti-de Sitter, which is dual to a conformal plasma on S2. We conclude about the effect of the bulk gravitational perturbations on the boundary metric and stress tensor, responsible for the geometric polarization. The computation of the tidal Love numbers is performed in both Regge-Wheeler gauge and the Kodama-Ishibashi gauge-invariant approach. We spell out how to convert the tidal Love numbers determined in these two formalisms and find perfect agreement. We also relate the Kodama-Ishibashi formalism with the Kovtun-Starinets approach, which is particularly well suited for the holographic analysis of black branes. This allows us to compare with the tidal Love number results for black branes in anti-de Sitter, also finding agreement in the relevant regime.
Generalised antenna functions for higher-order calculations
Authors: Fox Elliot , Glover Nigel , Marcoli Matteo 
Published: January 2025

Abstract
In this paper we discuss the definition, the construction and the implementation of generalised antenna functions for final-state radiation up to Next-to-Next-to-Leading Order (NNLO) in QCD. Generalised antenna functions encapsulate the singular behaviour of unresolved emissions when these occur within multiple hard radiators and not just two of them, as for traditional antenna functions. The construction of such objects is possible thanks to the recently proposed algorithm for building idealised antenna functions from a target set of infrared limits. Generalised antenna functions bring major simplifications in the assemblage of subtraction terms in the context of the antenna scheme at NNLO and beyond, as well as a substantial computational speedup of higher-order calculations. We discuss in detail the improvements on the formal and practical side for the computation of the NNLO correction to three-jet production at electron-positron colliders, providing a thorough numerical validation of the newly proposed scheme. For this calculation one can expect almost an order of magnitude speedup with respect to the original implementation.
Orbifold ETW brane and half-indices
Authors: Hatsuda Yasuyuki , Lin Hai , Okazaki Tadashi 
Published: January 2025

Abstract
We study the half-indices of $$ \mathcal{N} $$
N
= 4 super Yang-Mills theories of orthogonal and symplectic gauge groups. We find precise matching pairs of the half-indices as strong evidence of dualities of the half-BPS boundary conditions and interfaces. The half-indices encode the spectra of excitations on the holographically dual orbifold ETW brane and giant gravitons. The exact form of the index for the orbifold ETW giant gravitons is obtained from the giant graviton expansion of the half-index.
Impact of extreme magnetic fields on the QCD topological susceptibility in the vicinity of the crossover region
Authors: Brandt B. B. , Endrődi G. , Hernández J. J. Hernández , Markó G. 
Published: January 2025

Abstract
We present the first determination of the topological susceptibility from lattice QCD in the presence of strong background magnetic fields. Our simulations employ 2+1 flavours of stout-improved staggered quarks with physical masses and cover a broad range of temperatures and magnetic field values. The results are extrapolated to the continuum limit using four different lattice spacings and an eigenvalue reweighting technique to reduce discretisation errors. For low temperatures, our calculations show an enhancement of the topological susceptibility due to the magnetic field, compatible with predictions from chiral perturbation theory. At high temperatures, we observe the impact of inverse magnetic catalysis on the susceptibility.
Development and in-house validation of two real-time PCR methods for the detection of genome-editing events in soybean FAD2 gene variants
Authors: Heinz Steffen , Neusius Daniel , Eckermann Kolja Neil , Pietsch Klaus , Guertler Patrick 
Published: January 2025

Abstract
Since the commercialization of the first genetically modified (GM) crops, their relevance in agricultural applications has increased. Soybean (Glycine max) ranks as the most widely cultivated GM crop globally. With the advancements in site-specific genome-editing tools, the development of GM organisms (GMO) using new genomic techniques has accelerated, particularly in agriculture. In the US, a genome-edited soybean variety, Calyno, was developed with altered fatty acid composition by inactivating two members of the fatty acid desaturase 2 (FAD2) gene family, FAD2-1A and FAD2-1B, using TALEN technology. Although deregulated in the US, Calyno soybeans are not authorized for cultivation or import in the European Union and therefore cannot be placed on the European market. To address the need for reliable detection methods in routine analysis for GMO by public authorities, two event-specific qPCR methods were developed to detect the FAD2-1A-Δ63bp and FAD2-1B-Δ23bp gene variants in the Calyno soybeans. In the absence of reference material, methods were validated in-house using synthetic plasmids carrying the target regions’ sequences, following European Network of GMO Laboratories (ENGL) guidelines. Both assays meet the minimum performance requirements for GMO testing, demonstrating high sensitivity, qPCR efficiency, specificity and robustness. An interlaboratory comparison study further confirmed the reliability of these methods. These qPCR assays provide an effective tool for detecting the FAD2-1A-Δ63bp and FAD2-1B-Δ23bp gene variants in Calyno soybeans, supporting GMO testing requirements in the European Union and ensuring accurate monitoring of GM crops.
On Korteweg–de Vries and associated reciprocal moving boundary problems
Authors: Rogers Colin 
Published: January 2025

Abstract
Classes of moving boundary problems of Stefan-type are here shown to be exactly solvable in terms of classical Airy functions both for the linearised and solitonic Korteweg–de Vries equations. In the latter case, a Miura transformation is applied to a class of Airy-type similarity solutions derived via a Painlevé II reduction of the mKdV equation. Reciprocal transformations are then applied to obtain, in turn, Airy-type solution of associated moving boundary problems for both a nonlinear evolution equation of magma theory and a novel reciprocal Korteweg–de Vries equation which incorporates a source term.
Geometry modifications of circular saw blades to reduce aeroacoustic noise emissions
Authors: Güzel Kamil , Möhring Hans-Christian 
Published: January 2025

Abstract
In the manufacturing industries, noise is one of the most common health hazards at workplaces. In wood machining, for instance, circular sawing processes in particular produce high noise emissions that often exceed the permitted limits. The main source of noise is the rotating circular saw blade, whose aeroacoustic behavior is influenced by air turbulence on the tool contour. So far, no numerical approach to study and optimize the aeroacoustic noise emissions from circular saw blades has been investigated. This paper addresses this deficit and presents a methodology for modeling the flow-induced sound generation on rotating circular saw blades based on computational fluid dynamics (CFD) simulations. With the implementation of the acoustic analogy according to Ffowcs-Williams/Hawkings, the sound pressure levels could be calculated with sufficient accuracy. With deviations between 7 and 10%, the influence of the rotational speeds could be plausibly modeled. Based on the validated numerical model, geometry variants with various modifications were investigated regarding their potential for reducing sound pressure levels. Based on a conventional reference geometry, different chip space volumes and various modifications to the tooth rim and tooth shape were investigated and evaluated as part of simulative parameter studies. Sound pressure level reductions in the range of 2.2–10.8 dB were achieved. The results obtained and the systematic approach investigated provide a suitable set of instruments for industrial practice. Digital prototypes can be designed at an early stage in the product development phase of circular saw blades regarding their aeroacoustic properties.
Nanoscale reference and test materials for the validation of characterization methods for engineered nanomaterials — current state, limitations, and needs
Authors: Abram S.-L. , Tavernaro I. , Johnston L. J. , Zou S. , Resch-Genger U. 
Published: January 2025

AbstractThe rational design of engineered nanomaterials (NMs) with improved functionality and their increasing industrial application requires reliable, validated, and ultimately standardized characterization methods for their application-relevant, physicochemical key properties such as size, size distribution, shape, or surface chemistry. This calls for nanoscale (certified) reference materials (CRMs; RMs) and well-characterized reference test materials (RTMs) termed also quality control (QC) samples, assessed, e.g., in interlaboratory comparisons, for the validation and standardization of commonly used characterization methods. Thereby, increasing concerns regarding potential risks of NMs are also addressed and the road for safe and sustainable-by-design concepts for the development of new functional NMs and their use as nanomedicines is paved. With this respect, we will provide an overview of relevant international standardization and regulatory activities, definitions, and recommendations on characterization methods and review currently available organic or inorganic nanoscale CRMs, RMs, and RTMs, including their characterization or certification. In addition, we will highlight typical applications to streamline the regulatory approval process and improve manufacturability including the special challenges imposed by the colloidal nature and sometimes limited stability of NMs. Subsequently, we will critically assess the limitations of currently available nanoscale RMs and RTMs and address the gaps to be filled in the future such as the availability of NMs that come with reference data on properties other than commonly addressed particle size, such as surface chemistry or particle number concentration, or more closely resemble commercially available formulations or address application-relevant matrices.

Trigeminal artery anatomical aspects
Authors: Bulbuc Ionuț , Iliescu Dan Marcel , Dina Constantin , Ionescu Constantin , Bordei Petru 
Published: January 2025

Abstract
Purpose and background
The trigeminal artery is a rare anatomical variant, representing an embryonic vestige of the anastomosis between the internal carotid artery and the posterior circulator system, that can be asymptomatic or could have vast clinical manifestations produced by insufficient flow or by vascular nervous conflicts. This study is an anatomical presentation of 3 trigeminal artery cases observed at Medimar Imagistic Services Constanta.

Methods
The 3 trigeminal artery cases were discovered on a 860 magnetic resonance angiographies (0.35% of cases), made on a GE HD/e 8ch 1.5 T.

Results
In all 3 cases, the arteries were rising from the right internal carotid artery and one from the left internal carotid artery, in 2 cases the origin was on the superior surface, and in one case, on the anterolateral surface, in all 3 cases from C4 horizontal cavernous segment. The artery caliber was between 2.7 mm and 5.1 mm; the artery length was between 26 and 32 mm. Other associated vascular malformations were: partial or total basilar artery hypoplasia, in one case posterior communicant artery agenesis, contralateral vertebral artery hypoplasia, posterior cerebral artery hypoplasia (in 2 cases), and no anastomosis between the P1 segment of the posterior cerebral artery with the posterior communicating artery (one case).

Conclusions
While the trigeminal artery is a rare anatomical variant, it’s still a very important vessel situated in the posterior cerebral fossa, which needs to be taken into account in the case of neurosurgical interventions.
Supersonic discharge of cold gas inflators into rectangular ducts
Authors: Schnorr Eduard , Schütte Dennis , Scholz Peter , Radespiel Rolf 
Published: January 2025

Abstract
We discuss the supersonic discharge of cold gas inflators into confined ducts typical of curtain airbag inflation. The medium discharged from the cold gas inflators is helium. For this purpose, two different generic duct geometries are chosen to obtain one case without and one with wall interaction of the underexpanded jet. In the latter case, a so-called shock train develops, which dominates the flow topology. To quantify the flow field, time-resolved pressure transducers measure the static pressure at the duct walls and time-resolved particle image velocimetry measures the velocity in the far field of the underexpanded jet. Schlieren images illustrate the topology of the flow field. A simplified numerical model is then created that drastically reduces the required resources. The numerical model is verified against the experimental data and provides deeper insight into the outflow process. In particular, the interaction of the underexpanded jet with the duct walls and thus the resulting shock train are found to be sensitive. The numerical model can reconstruct the flow topology, pressure and velocity within acceptable limits. The experimental data and numerical results may serve as a basis for subsequent studies on airbag inflation or physically similar processes, especially for the validation of numerical methods.

Special screw corridors and imaging in pelvic ring trauma
Authors: Gänsslen Axel , Lindahl Jan , Lindtner Richard A. , Krappinger Dietmar , Staresinic Mario 
Published: January 2025

AbstractAdequate intraoperative visualization is mandatory for implant application in pelvic ring injuries. Several fluoroscopic X-ray views are in practical use. The gold standard primary X-ray is the anteroposterior view of the pelvis. In addition to this view, oblique views for pelvic ring instabilities and acetabular fractures are well defined. Combinations of these views allow better identification of osseous corridors for screw applications. These corridors are based on the 3-ring concept of the hemipelvis. For pelvic ring stabilization the main osseous corridors include the retrograde and antegrade superior ramus/anterior column corridor, the supraacetabular corridor and the gluteus medius pillar corridor. The radiographic anatomy of these corridors is described in detail for screw applications with definition of image intensifier angulations, risk zones and corridor parameters. This allows for intraoperative safe implant application.
Shifting trends in outpatient hand trauma care: a 16-year analysis at a major center in northern Germany
Authors: Tamulevicius Martynas , Bucher Florian , Dastagir Nadjib , Obed Doha , Vogt Peter M. , Dastagir Khaled 
Published: January 2025

Abstract
Background
Hand injuries are a leading cause of emergency department visits. Recent trends in hand trauma management reflect a shift toward outpatient care, driven by factors such as a shortage of skilled personnel or increasing cost pressures. This study analyzed these trends to propose updated management strategies for hand injuries.

Materials and methods
This retrospective cohort study included 14,414 patients treated at a certified major hand surgical trauma center between 2007 and 2022. Patients were divided into two groups: the earlier cohort (EC, 2007–2014) and the current cohort (CC, 2015–2022). Trends in inpatient and outpatient care, as well as hospitalization durations, were analyzed.

Results
During the study period, approximately one-third of all patients required inpatient treatment, with one-third of hospitalized patients staying at least one week, one-fifth staying two weeks, and one-tenth staying three or more weeks. Inpatient treatment rates decreased annually by 7%, while outpatient care increased by 5.3% annually. A significant shift toward outpatient management was noted for various injuries, including fractures, burns, lacerations, dislocations, complex injuries, and infections. Despite declining hospitalization rates, patients in the CC group had significantly longer hospital stays, reflecting the increasing complexity and severity of cases requiring admission (p < 0.001).

Conclusions
This study reveals a growing trend toward outpatient care for hand injuries, reflecting improved efficiency without compromising quality. Although fewer patients are hospitalized, those admitted require more intensive care, highlighting a shift toward ambulatory management for moderately severe cases. These findings emphasize the importance of initial injury management and underscore the need for expanding outpatient hand surgical care to meet growing demand in a rapidly changing healthcare landscape.

Respiratory support strategies in neonatal transport in the UK and Ireland
Authors: Jenkinson Allan , Dassios Theodore , Ratnavel Nandiran , Greenough Anne 
Published: January 2025

Abstract
Infants requiring interhospital transfer for a higher level of care in the neonatal period are at increased risk of adverse outcomes. Optimising respiratory management is an important priority. The aim of this survey was to investigate current respiratory support strategies in neonatal transport and identify opportunities for the optimisation of clinical care and future research. A survey of all 18 transport groups in Ireland and the UK was performed. A 10-item structured questionnaire was administered through consultant neonatologists or lead nurses from each transport group between May and June 2024. There was a 100% response rate. There was variation in the types of neonatal ventilator used, and they differed from those on NICUs. A variety of invasive strategies were used, but volume-targeted ventilation was the most common, although different ventilators can deliver different volumes despite apparently the same settings. Non-invasive strategies were used by all, with humidified high flow nasal cannula (HHFNC) being the most common. Continuous carbon dioxide (CO2) monitoring was used by most teams (94%): endotracheal CO2 assessments by 94% and transcutaneous monitoring by 70%. Only two teams employed closed loop automated oxygen control (CLAC).

Conclusion: There is heterogeneity in the ventilators and respiratory strategies used by transport groups. Future research opportunities should include the comparison of those strategies on short- and long‐term outcomes, as well as whether continuous CO2 monitoring and CLAC have important benefits.

What is Known:• Nearly one quarter of neonatal transfers in the UK and Ireland are in infants mechanically ventilated.• Optimising respiratory support strategies and reporting respiratory outcomes are research priorities in neonatal transport.

What is New:• Volume targeted ventilation is the most common respiratory support strategy used in neonatal transport groups in the UK and Ireland, with a heterogeneity of ventilators in use in neonatal transport versus in NICUs.• There is a paucity of data reporting respiratory outcomes following neonatal transport including outcomes related to mode of ventilation, continuous carbon dioxide monitoring and closed loop automated oxygen control.
