Published: August 2024

AbstractConducting an in-depth study on algorithms addressing the interaction problem in the fields of machine learning and IoT security involves a meticulous evaluation of performance measures to ensure global reliability. The study examines key metrics such as accuracy, precision, recall, and F1 scores across ten scenarios. The highly competitive algorithms showcase accuracy rates ranging from 95.5 to 98.2%, demonstrating their ability to perform accurately in various situations. Precision and recall measurements yield similar information about the model's capabilities. The achieved balance between accuracy and recovery, as determined by the F1 tests ranging from 95.2 to 98.0%, emphasizes the practical importance of data transfer in the proposed method. Numerical evaluation, in addition to an analysis of overall performance metrics, provides a comprehensive understanding of the algorithm's performance and identifies potential areas for improvement. This research leads to advancements in the theoretical vision of machine learning for IoT protection. It offers real-world insights into the practical use of robust models in dynamically changing situations. As the Internet of Things environment continues to evolve, the study's results serve as crucial guides, laying the foundation for developing strong and effective security systems in the realm of interaction between virtual and material reality.
De Sitter at all loops: the story of the Schwinger model
Authors: Anninos Dionysios , Anous Tarek , Fukelman Alan Rios 
Published: August 2024

Abstract
We consider the two-dimensional Schwinger model of a massless charged fermion coupled to an Abelian gauge field on a fixed de Sitter background. The theory admits an exact solution, first examined by Jayewardena, and can be analyzed efficiently using Euclidean methods. We calculate fully non-perturbative, gauge-invariant correlation functions of the electric field as well as the fermion and analyze these correlators in the late-time limit. We compare these results with the perturbative picture, for example by verifying that the one-loop contribution to the fermion two-point function, as predicted from the exact solution, matches the direct computation of the one-loop Feynman diagram. We demonstrate many features endemic of quantum field theory in de Sitter space, including the appearance of late-time logarithms, their resummation to de Sitter invariant expressions, and Boltzmann suppressed non-perturbative phenomena, with surprising late-time features.
Entanglement harvesting and quantum discord of alpha vacua in de Sitter space
Authors: Lin Feng-Li , Mondal Sayid 
Published: August 2024

Abstract
The CPT invariant vacuum states of a scalar field in de Sitter space, called α-vacua, are not unique. We explore the α-vacua from the quantum information perspective by a pair of static Unruh-DeWitt (UDW) detectors coupled to a scalar field with either monopole or dipole coupling, which are in time-like zero separation or space-like antipodal separation. The analytical form of the reduced final state of the UDW detector is derived. We study the entanglement harvesting and quantum discord of the reduced state, which characterize the quantum entanglement and quantum correlation of the underlying α-vacua, respectively. Our results imply that the quantum entanglement gravitated by de Sitter gravity behaves quite differently for time-like and space-like separations. It experiences “sudden death” for the former and grows for the latter as the measuring time or the value of α increases. This demonstrates the nonlocal nature of quantum entanglement. For the quantum discord, we find no “sudden death” behavior, and it experiences superhorizon suppression, which explains the superhorizon decoherence in the inflationary universe scenario. Overall, the time-like or space-like quantum entanglement and correlation behave differently on their dependence of α, measuring time and spectral gaps, with details discussed in this work.
On the (in)consistency of perturbation theory at finite temperature
Authors: Lowdon Peter , Philipsen Owe 
Published: August 2024

Abstract
A well-known difficulty of perturbative approaches to quantum field theory at finite temperature is the necessity to address theoretical constraints that are not present in the vacuum theory. In this work, we use lattice simulations of scalar correlation functions in massive ϕ4 theory to analyse the extent to which these constraints affect the perturbative predictions. We find that the standard perturbative predictions deteriorate even in the absence of infrared divergences at relatively low temperatures, and that this is directly connected to the analytic structure of the propagators used in the expansion. This suggests that the incorporation of non-perturbative thermal effects in the propagators is essential for a consistent perturbative formulation of scalar quantum field theories at finite temperature. By utilising the spectral constraints imposed on finite-temperature correlation functions, we explore how these effects manifest themselves in the lattice data, and discuss why the presence of distinct thermoparticle excitations provides a potential resolution to these issues.
What can abelian gauge theories teach us about kinematic algebras?
Authors: Armstrong-Williams Kymani , Nagy Silvia , White Chris D. , Wikeley Sam 
Published: August 2024

Abstract
The phenomenon of BCJ duality implies that gauge theories possess an abstract kinematic algebra, mirroring the non-abelian Lie algebra underlying the colour information. Although the nature of the kinematic algebra is known in certain cases, a full understanding is missing for arbitrary non-abelian gauge theories, such that one typically works outwards from well-known examples. In this paper, we pursue an orthogonal approach, and argue that simpler abelian gauge theories can be used as a testing ground for clarifying our understanding of kinematic algebras. We first describe how classes of abelian gauge fields are associated with well-defined subalgebras of the diffeomorphism algebra. By considering certain special subalgebras, we show that one may construct interacting theories, whose kinematic algebras are inherited from those already appearing in a related abelian theory. Known properties of (anti-)self-dual Yang-Mills theory arise in this way, but so do new generalisations, including self-dual electromagnetism coupled to scalar matter. Furthermore, a recently obtained non-abelian generalisation of the Navier-Stokes equation fits into a similar scheme, as does Chern-Simons theory. Our results provide useful input to further conceptual studies of kinematic algebras.
Generalized boost transformations in finite volumes and application to Hamiltonian methods
Authors: Li Yan , Wu Jia-Jun , Lee T.-S. H. , Young R. D. 
Published: August 2024

Abstract
The investigation of hadron interactions within lattice QCD has been facilitated by the well-known quantisation condition, linking scattering phase shifts to finite-volume energies. Additionally, the ability to utilise systems at finite total boosts has been pivotal in smoothly charting the energy-dependent behaviour of these phase shifts. The existing implementations of the quantization condition at finite boosts rely on momentum transformations between rest and moving frames, defined directly in terms of the energy eigenvalues. This energy dependence is unsuitable in the formulation of a Hamiltonian. In this work, we introduce a novel approach to generalise the three-momentum boost prescription, enabling the incorporation of energy-independent finite-volume Hamiltonians within moving frames. We demonstrate the application of our method through numerical comparisons, employing a phenomenological ππ scattering example.
Asymptotic symmetries from the string worldsheet
Authors: Du Zhengyuan , Liu Kangning , Song Wei 
Published: August 2024

Abstract
In IIB string theory on AdS3 background with NS-NS fluxes, we show that Brown-Henneaux asymptotic Killing vectors can be derived by requiring both the worldsheet equations of motion and Virasoro constraints are preserved near the asymptotic boundary of the target spacetime. The charges on the worldsheet that generate the corresponding transformations can be written down in both the Lagrangian formalism and Hamiltonian formalism. This provides a method of studying asymptotic symmetry of the target spacetime directly from worldsheet string theories, without using results from the supergravity limit. As an example, we apply this method to flat spacetime in three dimensions and obtain the BMS3 generators on the worldsheet theory.
Quantum charged black holes
Authors: Feng Yiji , Ma Hao , Mann Robert B. , Xue Yesheng , Zhang Ming 
Published: August 2024

Abstract
Within the framework of braneworld holography, we construct a quantum charged black hole localized on a three-dimensional anti-de Sitter (AdS) brane that intersects the asymptotic boundary of the four-dimensional AdS spacetime at the conformal defects and incorporates quantum backreaction effects from the conformal field theory (CFT) on the brane. This quantum charged black hole is an exact solution of the semiclassical gravitational equation corresponding to a theory with higher curvature gravity and nonminimally coupled nonlinear gauge field. In the framework of double holography, we investigate the thermodynamics of the quantum charged black hole from three perspectives: a pure bulk perspective, in which four-dimensional classical Einstein gravity couples to Maxwell electrodynamics and a codimension-one tensional brane; a brane perspective, where semiclassical higher curvature gravity is subject to quantum backreaction from the holographic CFT on the brane, yielding a quantum charged black hole; and a boundary perspective, where the defect CFT is coupled to a boundary CFT at the asymptotic boundary and the degrees of freedom for defect quantum conformal matter is considered. In so doing, we obtain doubly holographic formulations of both the first law of thermodynamics and the Smarr (energy) relations for the quantum charged black holes.
Extending global fits of 4D Composite Higgs Models with partially composite leptons
Authors: Carragher Ethan , Goh Kenn , Su Wei , White Martin , Williams Anthony G. 
Published: August 2024

Abstract
We perform the first convergent Bayesian global fits of 4D Composite Higgs Models with partially-composite third generation quarks and leptons based on the minimal SO(5) → SO(4) symmetry breaking pattern. We consider two models with the τ lepton and its associated neutrino in different representations of SO(5). Fitting each model with a wide array of experimental constraints allows us to analyse the Bayesian evidence and currently-observed fine-tuning of each model by calculating the Kullback-Leibler divergence between their respective priors and posteriors. Notably both models are found to be capable of satisfying all constraints simultaneously at the 3σ level at scales of < 5 TeV. From a Bayesian viewpoint of naturalness the model with leptons in the 14 and 10 representations is preferred over those in the 5 representation due to its lower fine-tuning. Finally, we consider the experimental signatures for the preferred parameters in these models, including lepton partner decay signatures and gluon-fusion produced Higgs signal strengths, and discuss their potential phenomenology at future high-luminosity LHC runs.
Spinning binary dynamics in cubic effective field theories of gravity
Authors: Brandhuber Andreas , Brown Graham R. , Pichini Paolo , Travaglini Gabriele , Matasan Pablo Vives 
Published: August 2024

Abstract
We study the binary dynamics of two Kerr black holes with arbitrary spin vectors in the presence of parity-even and parity-odd cubic deformations of gravity. We first derive the tree-level Compton amplitudes for a Kerr black hole in cubic gravity, which we then use to compute the two-to-two amplitudes of the massive bodies to leading order in the deformation and the post-Minkowskian expansion. The required one-loop computations are performed using the leading singularity approach as well as the heavy-mass effective field theory (HEFT) approach. These amplitudes are then used to compute the leading-order momentum and spin kick in cubic gravity in the KMOC formalism. Our results are valid for generic masses and spin vectors, and include all the independent parity-even and parity-odd cubic deformations of Einstein-Hilbert gravity. We also present spin-expanded expressions for the momentum and spin kicks, and the all-order in spin deflection angle in the case of aligned spins.
Loops in AdS: from the spectral representation to position space. Part III
Authors: Carmi Dean 
Published: August 2024

Abstract
We study loop amplitudes in anti de-Sitter space via the spectral representation. We consider loops of spinning fields and in particular gauge fields, and derive various identities connecting different families of loop diagrams, at different number of loops, different spins, different masses. Such identities are useful for the computation of Witten diagrams. Considering the theory of large-Nf conformal scalar QED defined on AdS space, we derive an analytic expression for the exact 4-point correlation function at sub-leading order in $$ \frac{1}{N_f} $$

Finally we study 4-point ladder diagrams with spinning fields, and we derive integral expressions for the spectral representation of a k-loop ladder diagram.

We consider 5d KK dualities, that is multiple 5d gauge theories with the same 6d infinite coupling limit. We provide a prescription to associate 4d$$ \mathcal{N} $$
N
= 1 quivers to the 5d dual quivers, such that the 4d quivers are also dual to each other. The 4d dualities are infrared dualities which can be checked matching global symmetry anomalies and in certain cases can be proven using basic Seiberg dualities sequentially. We also consider dualities obtained by Higgsing in two different ways the same 5d theory, in some simple examples.
Holography and Regge phases with U(1) charge
Authors: Fardelli Giulia , Fitzpatrick A. Liam , Li Wei 
Published: August 2024

Abstract
We use holography to study the large spin J limit of the spectrum of low energy states with charge Q under a U(1) conserved current in CFTs in d > 2 dimensions, with a focus on d = 3 and d = 4. For Q = 2, the spectrum of such states is known to be universal and properly captured by the long-distance limit of holographic theories, regardless of whether the CFT itself is holographic. We study in detail the holographic description of such states at Q > 2, by considering the contribution to the energies of Q scalar particles coming from single photon and graviton exchange in the bulk of AdS; in some cases, scalar exchange and bulk contact terms are also included. For a range of finite values of Q and J, we numerically diagonalize the Hamiltonian for such states and examine the resulting spectrum and wavefunctions as a function of the dimension ∆ of the charge-one operator and the central charges $$ {c}_{\mathcal{T}} $$

We discuss the extension of these results to the regime of parametrically large charge Q, as well as to what extent such results are expected to hold universally, beyond the limit of holographic CFTs. We compare our holographic computations to results from the conformal bootstrap for the 3d O(2) model at Q = 3 and Q = 4 and find excellent agreement.

Authors: Zimmerer Alexander , Nonnemacher Lars , Fischer Maximilian , Gebhardt Sebastian , Hofer André , Reichert Johannes , Wassilew Georgi 
Published: August 2024

Zusammenfassung
Operationsziel
Durchführung eines Transfers des M. gluteus maximus mit Refixation am Trochanter major zur Therapie der glutealen Insuffizienz.

Indikationen
Symptomatische gluteale Insuffizienz mit Atrophie und fettiger Degeneration der Glutealmuskeln > 50 % (Grad 3 nach Quartile) bei guter Kraftentwicklung des M. gluteus maximus.

Kontraindikationen
Geringe Atrophie oder fettige Degeneration von weniger als 50 % der Glutealmuskulatur, eingeschränkte Kraft des M. gluteus maximus, Infektionen.

Operationstechnik
Zunächst wird die Fascia lata dorsal des M. tensor fasciae latae inzidiert, wobei die Inzision bis ca. 1,5 cm proximal des Beckenkammes reicht. Eine zweite Inzision halbiert den M. gluteus maximus in Längsrichtung der Muskelfasern und wird in Richtung der Fascia lata nach distal des Trochanter major fortgesetzt. Durch die Inzisionen resultiert ein dreieckiger Muskellappen, welcher angehoben und in einen vorderen und einen hinteren Teil geteilt wird. Der posteriore Lappen wird über den Schenkelhals nach ventral gelegt und an der vorderen Kapsel und vorderen Kante des Trochanter major fixiert. Der anteriore Lappen wird direkt auf das proximale Femur platziert. Hierfür wird mit einer Kugelfräse eine Rinne im Bereich des proximalen Femurs präpariert, um den künftigen Footprint anzufrischen. Der anteriore Lappen wird von der Spitze des Trochanter major in Richtung des Ansatzes des M. vastus lateralis positioniert. Anschließend wird der anteriore Lappen mit transossären Nähten an der geschaffenen Rinne und unter dem angehobenen M. vastus lateralis in 15° Abduktion des Beines fixiert. Zur zusätzlichen Stabilisierung des sehnigen Teils des anterioren Lappens wird distal des Trochanter major eine Schraube eingebracht. Der M. vastus lateralis wird an der distalen Spitze des anterioren Lappens befestigt, und der verbleibende M. gluteus maximus wird mit der Fascia lata vernäht, um den anterioren Lappen abzudecken. Ergänzend kann ein Lappen des M. tensor fasciae latae mobilisiert und auf die Rekonstruktion adaptiert werden. Schichtweiser Wundverschluss.

Ergebnisse
Die gezeigte Technik eines M.-gluteus-maximus-Transfers stellt eine Methode zur Behandlung chronischer glutealer Insuffizienzen dar und verbessert in kurzzeitigen Follow-ups die Abduktionsfunktion sowie das Gangbild. Es wurden 15 Patienten (durchschnittliches Alter zum Operationszeitpunkt 62 Jahre) nach einem durchschnittlichen Follow-up von 2,5 Jahren nachuntersucht. Der modified Harris Hip Score (mHHS) verbesserte sich von 48 Punkten präoperativ auf 60 Punkte zum Follow-up. Präoperativ wiesen 100 % ein positives Trendelenburg-Zeichen auf, zum Follow-up Zeitpunkt waren es ca. 50 %.

ZusammenfassungAnliegen dieser Arbeit ist es, mittels explorativer Auswertungen verschiedene Verlaufstypen bipolarer Störungen und den damit verbundenen Merkmalen zu differenzieren und dabei insbesondere die Rolle von Bipolar-1- und Bipolar-2-Störung sowie den Einfluss der rezidivprophylaktischen Interventionen im Rahmen einer randomisierten, kontrollierten Therapiestudie zu klären. Es konnten 274 der ursprünglich 305 eingeschlossenen Personen untersucht werden. Patienten nahmen entweder an einer kognitiv-verhaltenstherapeutischen (SEKT) oder unterstützenden, patientenzentrierten (FEST) Gruppentherapie teil, welche sich über 4 Therapietage (entspricht 16 Doppelstunden) in monatlichem Abstand erstreckte. Depressive und manische Symptomatik wurde anhand des LIFE jeweils für die zurückliegenden 6 Monate bezogen auf jede Woche vor und nach der Interventionsphase sowie 6 und 12 Monate katamnestisch beurteilt. Die Effekte beider Gruppentherapien erwiesen sich als vergleichbar. Statistisch signifikant wurden in einem multivariaten Proportional-Hazards-Modell jedoch der Faktor Bipolar 1 und 2 sowie die Interaktion von Therapie mit Bipolar 1 und 2. Insbesondere profitierten Bipolar-2-Patienten von der SEKT-Intervention deutlich schlechter als von FEST. Es ergaben sich 3 Cluster, die Bipolar 1 (SEKT, keine Komorbidität, mehrheitlich keine Rezidive, jüngere Patienten) von Bipolar 2 (FEST, keine Komorbidität, mindestens 1, oft 2 Rezidive, ältere Patienten) und von einer heterogenen Gruppe (beide Interventionen, Komorbidität) trennten. Die Unterscheidung von Bipolar-1- und Bipolar-2-Störung ist wichtig und bislang unzureichend berücksichtigt. Bipolar-2-Störungen zeigen generell einen schlechten Verlauf und sprechen auf eine kognitive Verhaltenstherapie (SEKT) besonders schlecht an. Eine offene, unstrukturierte, unterstützende, patientenzentrierte Psychotherapie (FEST) ist generell wirksam.
Die Wirkung von elektromagnetischen Feldern auf Tendinopathien
Authors: Wilms Patrick , Schröder Jan , Scheit Lorenz , Reer Rüdiger 
Published: August 2024

Zusammenfassung
Zielsetzung
Tendinopathien sind Erkrankungen, die häufig eine langfristige Behandlung mit Analgetika, Physiotherapie, Orthesen und Schonung erfordern. Ziel dieser Studie war es, die Wirkung einer einmaligen Anwendung von hochenergetischem PEMF (pulsed electromagnetic field) auf das Schmerzempfinden und unspezifische Entzündungsparameter zu untersuchen.

Methode
34 Patienten wurden nach dem Zufallsprinzip einer Verumgruppe (10 min PEMF; 0,78 T) oder einer Placebogruppe (10 min Scheinbehandlung) zugeteilt. Vor und bis zu einer Woche nach der patientenverblindeten Behandlung (t1–t5) wurde der lokale Schmerzzustand (Algometrie) als Druckschmerzschwelle (PPT, pain pressure threshold) ermittelt. Gleichzeitig wurden Hitzeschockprotein 70 (HSP70) Blutkonzentrationen analysiert. Das zweifaktorielle Datenmodell wurde varianzanalytisch ausgewertet (2-way ANOVA). Die Studie wurde als „clinical trial“ registriert (DRKS00031321).

Ergebnisse
Nach Randomisierung und Drop-out (Verum n = 17, Placebo n = 13) ergaben Baseline-Analysen keine signifikanten Gruppenunterschiede für PPT (p = 0,096) oder HSP70 (p = 0,524), oder in Stichprobenmerkmalen (p > 0,05). Für die PEMF Gruppe zeigte sich ein signifikant stärkerer Anstieg (p = 0,045, η2 = 0,013) der Druckschmerzschwelle (PPT: +83 bis + 139 %) als für die Placebo Gruppe (PPT: +10 bis + 36 %). Für HSP70 zeigten sich keine assoziierten Effekte.

Schlussfolgerungen
Eine einmalige Anwendung von hochenergetischem PEMF führte zu einer sofortigen Placebo-Effekt bereinigten Schmerzlinderung über eine Woche bei Tendinopathie-Patienten, aber der vermutete zugrunde liegende HSP70-assoziierte Entzündungsweg konnte nicht bestätigt werden.
