Personality Disorders, Narcissism and Borderline-Organization
Authors: Krüger Reinhard T. 
Published: January 2024

AbstractPatients with a borderline organization or other personality disorders suffer from a structural disorder. Their metacognitive processes are fixed in a character resistance and cause severe relationship disorders in the present. However, they experience the rigid defenses they developed in childhood as part of their identity. This fixation also disrupts the therapeutic relationship. The therapist is required to make an internal paradigm shift. She justifies her own appropriate negative affect, triggered by the patient's character resistance, in the therapeutic relationship and uses it in a therapeutically beneficial manner. In doing so, she uses the principle of response instead of interpretation. The constellation of metacognitive ego states enables the patient to gain ego control over his neurotic acting out in equivalence mode. This work is a central action method in disorder-specific psychodrama therapy. The therapist works not only with dysfunctional parts of the self, but also works out the positive meaning of the patient's rigid metacognitive defense pattern within the framework of his or her self-regulation. The treatment of metacognitive disorder is the prerequisite for long-term success in the therapy of people with a personality disorder. The disorder-specific psychodramatic action methods qualitatively enhance the depth psychological, behavioral and systemic psychotherapy of people with personality disorders.
Depressive Disorders, Masochism and Suicidale Crises
Authors: Krüger Reinhard T. 
Published: January 2024

AbstractThe disorder-specific psychodrama therapy of depressive disorders develops the patient’s self with the help of psychodramatic dialogue with role reversal and, if necessary, works directly metacognitively on his masochistic self-censorship. The seven steps of psychodramatic dialogue described in this chapter are a central method of disorder-specific psychodrama therapy. In an inner conflict, they shape both the inner self-image and the object image in the as-if mode. As a result, the patient becomes more courageous and realistic in his relationship conflicts. Without realizing it, he spontaneously changes his own behavior in everyday life, when he has psychosomatically expanded his inner object image of his conflict partner by acting as-if in a role reversal. As a theory-based action method, the psychodramatic dialogue with role reversal complements the disorder-specific approach to depression in depth psychological, behavioral and systemic psychotherapy. The psychosomatic level of psychodramatic action in the as-if mode helps to dissolve the blockage of self-development even in the case of severe depression bordering on psychosis as well as in suicidal crises.
The majoron coupling to charged leptons
Authors: Herrero-Brocal Antonio , Vicente Avelino 
Published: January 2024

Abstract
The particle spectrum of all Majorana neutrino mass models with spontaneous violation of global lepton number include a Goldstone boson, the so-called majoron. The presence of this massless pseudoscalar changes the phenomenology dramatically. In this work we derive general analytical expressions for the 1-loop coupling of the majoron to charged leptons. These can be applied to any model featuring a majoron that have a clear hierarchy of energy scales, required for an expansion in powers of the low-energy scale to be valid. We show how to use our general results by applying them to some example models, finding full agreement with previous results in several popular scenarios and deriving novel ones in other setups.
Apparently superluminal superfluids
Authors: Kourkoulou Ioanna , Landry Michael J. , Nicolis Alberto , Parmentier Klaas 
Published: January 2024

Abstract
We consider the superfluid phase of a specific renormalizable relativistic quantum field theory. We prove that, within the regime of validity of perturbation theory and of the superfluid effective theory, there are consistent and regular vortex solutions where the superfluid’s velocity field as traditionally defined smoothly interpolates between zero and arbitrarily large superluminal values. We show that this solution is free of instabilities and of superluminal excitations. We show that, in contrast, a generic vortex solution for an ordinary fluid does develop an instability if the velocity field becomes superluminal. All this questions the characterization of a superfluid velocity field as the actual velocity of “something”.
Hexagonalization of Fishnet integrals. Part II. Overlaps and multi-point correlators
Authors: Olivucci Enrico 
Published: January 2024

Abstract
This work presents the building-blocks of an integrability-based representation for multi-point Fishnet Feynman integrals with any number of loops. Such representation relies on the quantum separation of variables (SoV) of a non-compact spin-chain with symmetry SO(1, 5) explained in the first paper of this series. The building-blocks of the SoV representation are overlaps of the wave-functions of the spin-chain excitations inserted along the edges of a triangular tile of Fishnet lattice. The zoology of overlaps is analyzed along with various worked out instances in order to achieve compact formulae for the generic triangular tile. The procedure of assembling the tiles into a Fishnet integral is presented exhaustively. The present analysis describes multi-point correlators with disk topology in the bi-scalar limit of planar γ-deformed $$ \mathcal{N} $$
N
= 4 SYM theory, and it verifies some conjectural formulae for hexagonalisation of Fishnets CFTs present in the literature. The findings of this work are suitable of generalization to a wider class of Feynman diagrams.
Supersymmetric backgrounds from λ-deformations
Authors: Itsios Georgios , Sfetsos Konstantinos , Siampos Konstantinos 
Published: January 2024

Abstract
We provide the first supersymmetric embedding of an integrable λ-deformation to type-II supergravity. Specifically, that of the near horizon of the NS1-NS5 brane intersection, geometrically corresponding to AdS3 × S3 × T4. We show that the deformed background preserves 1/4 of the maximal supersymmetry. In the Penrose limit we show that it preserves no-more than one half of the maximal supersymmetry.
Unified treatment of null and spatial infinity IV: angular momentum at null and spatial infinity

Abstract
In a companion paper [1] we introduced the notion of asymptotically Minkowski spacetimes. These space-times are asymptotically flat at both null and spatial infinity, and furthermore there is a harmonious matching of limits of certain fields as one approaches i° in null and space-like directions. These matching conditions are quite weak but suffice to reduce the asymptotic symmetry group to a Poincaré group $$ {\mathfrak{p}}_{i{}^{\circ}} $$

Tame symmetric algebras of period four
Authors: Erdmann Karin , Hajduk Adam , Skowyrski Adam 
Published: January 2024

AbstractIn this paper, we are concerned with the structure of tame symmetric algebras $$\Lambda $$
Λ
of period four (TSP4 algebras for short). For a tame algebra, the number of arrows starting or ending at a given vertex cannot be large. Here we will mostly focus on the case when the Gabriel quiver of $$\Lambda $$
Λ
is biserial, that is, there are at most two arrows ending and at most two arrows starting at each vertex. We present a range of properties (with relatively short proofs) which must hold for the Gabriel quiver of such an algebra. In particular, we show that triangles (and squares) appear naturally, so as for weighted surface algebras (Erdmann and Skowroński in J Algebra 505:490–558, 2018, J Algebra 544:170–227, 2020, J Algebra 569:875–889, 2021). Furthermore, we prove results on the minimal relations defining the ideal I for an admissible presentation of $$\Lambda $$
Λ
in the form KQ/I. This will be the input for the classification of all TSP4 algebras with biserial Gabriel quiver.
Orbital instability of periodic waves for scalar viscous balance laws
Authors: Álvarez Enrique , Angulo Pava Jaime , Plaza Ramón G. 
Published: January 2024

AbstractThe purpose of this paper is to prove that, for a large class of nonlinear evolution equations known as scalar viscous balance laws, the spectral (linear) instability condition of periodic traveling wave solutions implies their orbital (nonlinear) instability in appropriate periodic Sobolev spaces. The analysis is based on the well-posedness theory, the smoothness of the data-solution map, and an abstract result of instability of equilibria under nonlinear iterations. The resulting instability criterion is applied to two families of periodic waves. The first family consists of small amplitude waves with finite fundamental period which emerge from a local Hopf bifurcation around a critical value of the velocity. The second family comprises arbitrarily large period waves which arise from a homoclinic (global) bifurcation and tend to a limiting traveling pulse when their fundamental period tends to infinity. In the case of both families, the criterion is applied to conclude their orbital instability under the flow of the nonlinear viscous balance law in periodic Sobolev spaces with same period as the fundamental period of the wave.

Abstract
Purpose
To date, it remains unclear whether superior or anterior plating is the best option for treating midshaft clavicular fractures. The aim of this study was to compare both techniques with regard to the incidence of implant removal due to implant irritation, risk of complications, time to union, and function.

Methods
In this retrospective cohort study, all midshaft clavicular fractures treated operatively between 2017 and 2020 in two hospitals in Switzerland were analyzed. The participating hospitals differed with regard to their standard practice; one offered superior plating only, while the other predominantly employed an anterior plate. The primary outcome was the incidence of implant removal for irritation. Secondary outcomes were time to union, complications, re-interventions, and range of motion during the follow-up period of at least 6 months.

Results
In total, 168 patients were included in the study of which 81 (48%) received anterior plating and 87 (52%) superior plating. The overall mean age was 45 years (SD 16). There was no significant difference between anterior and superior plating with regard to implant removal (58.5% versus 57.1%, p = 0.887), infection (5.7% versus 1.8%, p = 0.071), and time to union (median 48 weeks versus 52 weeks, p = 0.643). Data on range of motion were available in 71 patients. There was no significant difference in anteflexion (median 180 degrees anterior versus 180 degrees superior) and abduction (median 180 degrees anterior versus 180 degrees superior) between the two groups.

Conclusion
This retrospective cohort study did not find sufficient evidence to recommend one implant position over the other for midshaft clavicular fractures with regard to removal due to irritation. Time to union was similar and Infections were equally rare in both groups. Notably, a considerable number of patients in both groups had their implants removed due to irritation. Larger prospective studies are needed to determine how much plate position contributes to the occurrence of irritation and whether other patient or implant-related factors might play a role. Until this is clarified, implant position should be based on surgeons preference and experience.
Wire-EDM performance and surface integrity of Inconel 718 with unique microstructural features fabricated by laser powder bed fusion
Authors: Gokcekaya Ozkan , Günen Ali , Ceritbinmez Ferhat , Bahador Abdollah , Nakano Takayoshi , Çetin Melik 
Published: January 2024

AbstractInconel 718 alloy is difficult to machine using conventional methods due to its physical properties. Thereby, additive manufacturing (AM) of IN718 components with near-net shapes has been extensively studied. Even though AM processes provide shape and size accuracy, there is still the need for the machining of the AM-processed components to achieve the final shape of a component. Laser powder bed fusion (LPBF) has been successfully utilized to fabricate near-net shape IN718 components; moreover, the microstructure of LPBF-IN718 was unique owing to the AM processing, resulting in differences in grain size, grain boundary characteristics, and grain orientations. Furthermore, these microstructural characteristics are expected to alter the machining performance of IN718. Therefore, this study investigated the wire electro-discharge machining (WEDM) performance of LPBF-718 samples compared to wrought IN718 while focusing on the unique microstructure characteristics of LPBF-IN718 samples (lamella, single-crystal, ploy-crystal). Three different cutting strategies (rough, semi-finish, and finish) were implemented to understand the performance of the multi-pass cutting phenomenon and its effect on the surface of IN718. For all samples, rough (single pass) cutting displayed high roughness, while finish (three passes) cutting exhibited good surface quality. Compositional analyses on the machined surface showed debris formation including Zn and Cu-containing recast material, indicating wire erosion. The surface of single-crystal LPBF-IN718 after the WEDM process was smooth owing to its large grain size and less amount of grain boundary, resulting in slow cutting speed but a good surface finish. Thus, this study, for the first time, investigated the effect of unique microstructural characteristics of LPBF-fabricated IN718 on WEDM performance and machined surface quality.
Die „Reerdigung“

Published: January 2024

Zusammenfassung
Hintergrund
Die Reerdigung stellt eine neue Bestattungsform dar, bei der ein menschlicher Leichnam durch natürliche und mechanische Prozesse in 40 Tagen zu Erdsubstrat umgewandelt wird. Für die forensische Evaluation untersuchte das Institut für Rechtsmedizin Leipzig Proben aus den Überresten des Prozesses.

Methodik
Knochen‑, Erd- und Haarproben wurden von zwei Verstorbenen entnommen und mit molekularbiologischen, toxikologischen, morphologisch-osteologischen und bodenkundlichen Methoden untersucht.

Ergebnisse
Die DNA in den Knochen ist nach 40 Tagen degradiert und im zermahlenen, der Erde beigemischten Zustand nicht mehr mit herkömmlichen Methoden nachweisbar. Ein toxikologischer Nachweis von prämortal eingenommenen Medikamenten war analyt- und matrixabhängig teilweise möglich. Morphologisch-osteologisch entsprechen die Knochen einer Liegezeit von 20–50 Jahren. Die entstehende Erde weist die Eigenschaften von Humus auf.

Diskussion
Die neue Bestattungsform bedarf vor Beginn des Prozesses einer zweiten Leichenschau. Aus forensisch-toxikologischer Sicht ist die vereinzelte Nachweisbarkeit von Wirkstoffen tendenziell positiv zu bewerten, da im Gegensatz zur Kremierung potenziell nötige toxikologische Nachuntersuchungen teilweise noch möglich sein könnten. Für die Erdprobe vor und nach Durchmischung von Erde und Knochenmehl konnten hier keine für eine DNA-Analyse geeigneten DNA-Mengen gewonnen werden. Es ist somit davon auszugehen, dass nach der Bestattung der Überreste bei einer weiteren Zersetzung keine humane DNA aus Mischproben zur Identifizierung gewonnen werden kann. Die Erdproben weisen neben den Knochen mikro- sowie makroskopisch keine Spuren von humanem Weichgewebe auf. Das Resultat spricht dafür, dass innerhalb von 40 Tagen die Umwandlung zu Erde stattfindet. Die geringe Zahl der in dieser Pilotstudie untersuchten Leichen stellt eine Limitation dar. Weitere Untersuchungen zur Vergrößerung der Grundgesamtheit sind geplant.
A State Space for 3D Euclidean Yang–Mills Theories
Authors: Cao Sky , Chatterjee Sourav 
Published: January 2024

AbstractIt is believed that Euclidean Yang–Mills theories behave like the massless Gaussian free field (GFF) at short distances. This makes it impossible to define the main observables for these theories—the Wilson loop observables—in dimensions greater than two, because line integrals of the GFF do not exist in such dimensions. Taking forward a proposal of Charalambous and Gross, this article shows that it is possible to define Euclidean Yang–Mills theories on the 3D unit torus as ‘random distributional gauge orbits’, provided that they indeed behave like the GFF in a certain sense. One of the main technical tools is the existence of the Yang–Mills heat flow on the 3D torus starting from GFF-like initial data, which is established in a companion paper. A key consequence of this construction is that under the GFF assumption, one can define a notion of ‘regularized Wilson loop observables’ for Euclidean Yang–Mills theories on the 3D unit torus.

AbstractCompressed Sensing (CS) encompasses a broad array of theoretical and applied techniques for recovering signals, given partial knowledge of their coefficients, cf. Candés (C. R. Acad. Sci. Paris, Ser. I 346, 589–592 (2008)), Candés et al. (IEEE Trans. Inf. Theo (2006)), Donoho (IEEE Trans. Inf. Theo. 52(4), (2006)), Donoho et al. (IEEE Trans. Inf. Theo. 52(1), (2006)).

Motivated by our interest in the mathematics behind Magnetic Resonance Imaging (MRI) and CS, we employ convex analysis techniques to analytically determine equivalents of Lagrange multipliers for optimization problems with inequality constraints, specifically a weighted LASSO with voxel-wise weighting. We investigate this problem under assumptions on the fidelity term $$\left\Vert Ax-b\right\Vert _2^2$$

The objective of this work is to explore the relationship between Lagrange multipliers and the constraints of a weighted variant of LASSO, specifically in the mentioned cases where this relationship can be computed explicitly. As they scale the regularization terms of the weighted LASSO, Lagrange multipliers serve as tuning parameters for the weighted LASSO, prompting the question of their potential effective use as tuning parameters in applications like MR image reconstruction and denoising. This work represents an initial step in this direction.
Pioneering gut health improvements in piglets with phytogenic feed additives
Authors: Yu Sung Joon , Morris Andrew , Kayal Advait , Milošević Ivan , Van Thi Thu Hao , Bajagai Yadav Sharma , Stanley Dragana 
Published: January 2024

Abstract
This research investigates the effects of phytogenic feed additives (PFAs) on the growth performance, gut microbial community, and microbial metabolic functions in weaned piglets via a combined 16S rRNA gene amplicon and shotgun metagenomics approach. A controlled trial was conducted using 200 pigs to highlight the significant influence of PFAs on gut microbiota dynamics. Notably, the treatment group revealed an increased gut microbiota diversity, as measured with the Shannon and Simpson indices. The increase in diversity is accompanied by an increase in beneficial bacterial taxa, such as Roseburia, Faecalibacterium, and Prevotella, and a decline in potential pathogens like Clostridium sensu stricto 1 and Campylobacter. Shotgun sequencing at the species level confirmed these findings. This modification in microbial profile was coupled with an altered profile of microbial metabolic pathways, suggesting a reconfiguration of microbial function under PFA influence. Significant shifts in overall microbial community structure by week 8 demonstrate PFA treatment’s temporal impact. Histomorphological examination unveiled improved gut structure in PFA-treated piglets. The results of this study indicate that the use of PFAs as dietary supplements can be an effective strategy, augmenting gut microbiota diversity, reshaping microbial function, enhancing gut structure, and optimising intestinal health of weaned piglets providing valuable implications for swine production.

Key points
• PFAs significantly diversify the gut microbiota in weaned piglets, aiding balance.
• Changes in gut structure due to PFAs indicate improved resistance to weaning stress.
• PFAs show potential to ease weaning stress, offering a substitute for antibiotics in piglet diets.
