Authors: Punnekkat Sasikumar , Markovic Tijana , León Miguel , Leander Björn , Dehlaghi-Ghadim Alireza , Strandberg Per Erik 
Published: June 2024

AbstractThe recent advances in digitalization, improved connectivity and cloud based services are making a huge revolution in manufacturing domain. In spite of the huge potential benefits in productivity, these trends also bring in some concerns related to safety and security to the traditionally closed industrial operation scenarios. This paper presents a high-level view of some of the research results and technological contributions of the InSecTT Project for meeting safety/security goals. These technology contributions are expected to support both the design and operational phases in the production life cycle. Specifically, our contributions spans (a) enforcing stricter but flexible access control, (b) evaluation of machine learning techniques for intrusion detection, (c) generation of realistic process control and network oriented datasets with injected anomalies and (d) performing safety and security analysis on automated guided vehicle platoons.
On classical de Sitter solutions and parametric control
Authors: Andriot David , Ruehle Fabian 
Published: June 2024

Abstract
Finding string backgrounds with de Sitter spacetime, where all approximations and corrections are controlled, is an open problem. We revisit the search for de Sitter solutions in the classical regime for specific type IIB supergravity compactifications on group manifolds, an under-explored corner of the landscape that offers an interesting testing ground for swampland conjectures. While the supergravity de Sitter solutions we obtain numerically are ambiguous in terms of their classicality, we find an analytic scaling that makes four out of six compactification radii, as well as the overall volume, arbitrarily large. This potentially provides parametric control over corrections. If we could show that these solutions, or others to be found, are fully classical, they would constitute a counterexample to conjectures stating that asymptotic de Sitter solutions do not exist. We discuss this point in great detail.
One-loop elastic amplitudes from tree-level elasticity in 2d
Authors: Fabri Matheus , Polvara Davide 
Published: June 2024

Abstract
In this paper we extend the study initiated in [1] to the computation of one-loop elastic amplitudes. We consider 1+1 dimensional massive bosonic Lagrangians with polynomial-like potentials and absence of inelastic processes at the tree level; starting from these assumptions we show how to write sums of one-loop diagrams as products and integrals of tree-level amplitudes. We derive in this way a universal formula for the one-loop two-to-two S-matrices in terms of tree S-matrices. We test our results on different integrable theories, such as sinh-Gordon, Bullough-Dodd and the full class of simply-laced affine Toda theories, finding perfect agreement with the bootstrapped S-matrices known in the literature. We show how Landau singularities in amplitudes are naturally captured by our universal formula while they are lost in results based on unitarity-cut methods implemented in the past [2, 3].
Floquet SYK wormholes

Published: June 2024

Abstract
We study the non-equilibrium dynamics of two coupled SYK models, conjectured to be holographically dual to an eternal traversable wormhole in AdS2. We consider different periodic drivings of the parameters of the system. We analyze the energy flows in the wormhole and black hole phases of the model as a function of the driving frequency. Our numerical results show a series of resonant frequencies in which the energy absorption and heating are enhanced significantly and the transmission coefficients drop, signalling a closure of the wormhole. These frequencies correspond to part of the conformal tower of states and to the boundary graviton of the dual gravitational theory. Furthermore, we provide evidence supporting the existence of a hot wormhole phase between the black hole and wormhole phases. When driving the strength of the separate SYK terms we find that the transmission can be enhanced by suitably tuning the driving.
Effect of continuum states on the double-heavy hadron spectra
Authors: Castellà Jaume Tarrús 
Published: June 2024

Abstract
We present the leading order coupling of double-heavy hadrons to heavy hadron pairs in Born-Oppenheimer effective field theory. We obtain the expressions for the contribution of heavy hadron pairs to the masses and widths of double-heavy hadrons. We apply our result for the specific case of the coupling of the lowest lying heavy hybrids and $$ {D}_{(s)}^{\left(\ast \right)}{\overline{D}}_{(s)}^{\left(\ast \right)}\left({B}_{(s)}^{\left(\ast \right)}{\overline{B}}_{(s)}^{\left(\ast \right)}\right) $$

Planar RG flows on line defects
Authors: Nagar Ivri , Sever Amit , Zhong De-liang 
Published: June 2024

Abstract
We study a class of renormalization group flows on line defects that can be described by a generalized free field with ordered planar contractions on the line. They are realized, for example, in large N gauge theories with matter in the fundamental representation and arise generically in non-relativistic CFTs. We analyze the flow exactly and compute the change in the g-function between the UV and IR fixed points. We relate the result to the change in the two-point function of the displacement operator and check the monotonicity of the defect entropy along the flow analytically. Finally, we give a general realization of this type of flow starting from the direct sum of the IR fixed point and a trivial line. This type of defect renormalization group flow parallels the well-studied case of double-trace flow.
Liouville irregular states of half-integer ranks
Authors: Hamachika Ryo , Nakanishi Tomoki , Nishinaka Takahiro , Tanigawa Shou 
Published: June 2024

Abstract
We conjecture a set of differential equations that characterizes the Liouville irregular states of half-integer ranks, which extends the generalized AGT correspondence to all the (A1, Aeven) and (A1, Dodd) types Argyres-Douglas theories. For lower half-integer ranks, our conjecture is verified by deriving it as a suitable limit of a similar set of differential equations for integer ranks. This limit is interpreted as the 2D counterpart of a 4D RG-flow from (A1, D2n) to (A1, D2n−1). For rank 3/2, we solve the conjectured differential equations and find a power series expression for the irregular state |I(3/2)〉. For rank 5/2, our conjecture is consistent with the differential equations recently discovered by H. Poghosyan and R. Poghossian.
Thermodynamics of the 3-dimensional Einstein-Maxwell system
Authors: Miyashita Shoichiro 
Published: June 2024

Abstract
Recently, I studied the thermodynamical properties of the Einstein-Maxwell system with a box boundary in 4-dimensions [1]. In this paper, I investigate those in 3-dimensions using the zero-loop saddle-point approximation and focusing only on a simple topology sector as usual. Similar to the 4-dimensional case, the system is thermodynamically well-behaved when Λ < 0 (due to the contribution of the “bag of gold” saddles). However, when Λ = 0, a crucial difference to the 4-dimensional case appears, i.e. the 3-dimensional system turns out to be thermodynamically unstable, while the 4-dimensional one is thermodynamically stable. This may offer two options for how we think about the thermodynamics of 3-dimensional gravity with Λ = 0. One is that the zero-loop approximation or restricting the simple topology sector is not sufficient for 3-dimensions with Λ = 0. The other is that 3-dimensional gravity is really thermodynamically unstable when Λ = 0.

In the latter case, the asymptotic accumulation of these eigenvalues at zero has been determined by Kirsch and Simon. A similar regime occurs for potentials that are not asymptotically monotone but oscillatory.

Zusammenfassung
Hintergrund
Die Inanspruchnahme der psychotherapeutischen Sprechstunde am Arbeitsplatz (PT-A) wurde bislang in Großunternehmen (GU) untersucht. Diese unterscheiden sich strukturell von mittleren und Klein(st)unternehmen (KMU). Unterschiede der Nutzerprofile einer PT‑A hinsichtlich psychosomatischer Gesundheit, arbeitsbezogener Selbstwirksamkeit und Arbeitsfähigkeit sowie des psychosozialen Sicherheitsklimas (PSC) abhängig von der Unternehmensgröße wurden bisher kaum betrachtet.

Methoden
In der Interventionsstudie „Frühe Intervention am Arbeitsplatz“ (friaa) wurden zwischen 09/2021 und 01/2023 an einer PT‑A interessierte Beschäftigte aus GU und KMU deutschlandweit befragt. Mittels t‑ und χ2-Tests wurden Unterschiede zwischen Beschäftigten in GU (n = 439) und KMU (n = 109) hinsichtlich F‑Diagnosen nach ICD-10 („International Statistical Classification of Diseases and Related Health Problems“; psychische und Verhaltensstörungen), Depressivität (PHQ-9), Ängstlichkeit (GAD-2), allgemeinen Funktionsniveaus (GAF), somatischer Symptombelastung (SSS-8), Gesundheit (VR-12), Arbeitsfähigkeit (WAI), Selbstwirksamkeit (SOSES) und psychosozialen Sicherheitsklimas (PSC-4) geprüft und mittels Korrelationsanalyse explorativ deren Zusammenhänge untersucht.

Ergebnisse
Beide Gruppen zeigten sich ähnlich stark beansprucht. In GU wurden aus Sicht der Beschäftigten psychosoziale Themen signifikant häufiger thematisiert als in KMU mit einer mittleren Effektgröße. Die Studie lieferte erste Hinweise, dass in GU positive Zusammenhänge des PSC‑4 mit SOSES und WAI sowie negative mit PHQ‑9 und SSS‑8 vorliegen.

Diskussion
Die vergleichbare psychische Beanspruchung der Beschäftigten in GU und KMU weist auf den Bedarf von verhältnis- und verhaltenspräventiven Maßnahmen unabhängig von der Unternehmensgröße hin. Vor allem in KMU sollte die Thematisierung psychosozialer Gesundheit einen größeren Stellenwert einnehmen.
Fine mapping a QTL for BYDV-PAV resistance in maize

Published: June 2024

AbstractBarley yellow dwarf (BYD) is one of the economically most important virus diseases of cereals worldwide, causing yield losses up to 80%. The means to control BYD are limited, and the use of genetically resistant cultivars is the most economical and environmentally friendly approach. The objectives of this study were i) to identify the causative gene for BYD virus (BYDV)-PAV resistance in maize, ii) to identify single nucleotide polymorphisms and/or structural variations in the gene sequences, which may cause differing susceptibilities to BYDV-PAV of maize inbreds, and iii) to characterize the effect of BYDV-PAV infection on gene expression of susceptible, tolerant, and resistant maize inbreds. Using two biparental mapping populations, we could reduce a previously published quantitative trait locus for BYDV-PAV resistance in maize to ~ 0.3 Mbp, comprising nine genes. Association mapping and gene expression analysis further reduced the number of candidate genes for BYDV-PAV resistance in maize to two: Zm00001eb428010 and Zm00001eb428020. The predicted functions of these genes suggest that they confer BYDV-PAV resistance either via interfering with virus replication or by inducing reactive oxygen species signaling. The gene sequence of Zm00001eb428010 is affected by a 54 bp deletion in the 5`-UTR and a protein altering variant in BYDV-PAV-resistant maize inbreds but not in BYDV-PAV-susceptible and -tolerant inbreds. This finding suggests that altered abundance and/or properties of the proteins encoded by Zm00001eb428010 may lead to BYDV-PAV resistance.

Abstract
Trace element concentrations in magnetite are dictated by the petrogenetic environment and by the physico-chemical conditions during magmatic, hydrothermal, or sedimentary processes. This makes magnetite chemistry a useful tool in the exploration of ore-forming processes. We describe magnetite compositions from Ni-Cu-(PGE)-sulfide mineralized rocks from seven mafic–ultramafic intrusions peripheral to the Mesoproterozoic AMCG (anorthosite-mangerite-charnockite-granite) suite of the Kunene Complex of Angola and Namibia to investigate metallogenic processes through the geochemical characterization of Fe-oxides, which were analyzed in-situ via Electron Probe Microanalysis (EPMA), and Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry (LA-ICP-MS). We identified magmatic magnetite, segregated from both a silicate liquid and an immiscible sulfide liquid. Elements like Cr, Co and V suggest that the sulfide-related magnetite segregated from a relatively primitive Fe-rich monosulfide solid solution (MSS). Secondary Cr-rich magnetite appears in intrusions with abundant chromite or Cr-spinel. Two types of hydrothermal magnetite were identified, related to the pervasive replacement of sulfides and a late-stage, low-T fluid circulation event. Magnetite replacing sulfides is associated with serpentinized ultramafic rocks and is preferentially observed in the intrusions with the highest base and precious metal tenors. The high concentration of Ni, Co, Cu, Pd, As and Sb in these grains is corroborated by the identification of micron-size PGE mineral inclusions. We infer that serpentinization during hydrothermal fluid circulation was accompanied by desulphurization of sulfides with metal remobilization and reconcentration to generate magnetite carrying Pd microinclusions. We suggest that the highly serpentinized ultramafic rocks in the Kunene Complex region may become a possible target for economic Ni-Cu-(PGE) mineralization.
Tieboutian clubs revisited
Authors: Heikkila Eric J. , Coutin Jordy 
Published: June 2024

AbstractThis paper examines the evolution of Tieboutian clubs over time and across metropolitan regions. We address this topic by examining a large set of socioeconomic characteristics of metropolitan regions to assess empirically whether and how those member attributes may figure into a Tiebout sorting process. The method entails factor analysis to reduce an initial set of forty-nine variables to a much smaller number of factors that represent groups of intercorrelated variables. An analysis of variance is then undertaken on the corresponding factor scores to assess whether census tracts within municipalities are more alike than those between municipalities. We do this for the Los Angeles metropolitan region using census data from 1970, 1990 and 2020, and we repeat the process for the twenty largest metropolitan regions (core-based statistical areas) in the USA for 2020. Several key results emerge from this analysis. While in most cases seven or eight factors emerge repeatedly, four are most persistent and ubiquitous; these pertain to economic class, race, age cohort and immigration status. These are, in effect, the most enduring fundamental aspects of the socioeconomic landscape in metropolitan regions in the USA. The final question addressed by our work links back to the original motivation, which is to assess the role of municipalities in the formation of these clubs. We do so for the twenty largest metropolitan regions in the USA. The results from our analyses of variance are compelling. With very few exceptions we find that census tracts with similar club characteristics have a strong tendency to be co-located within the same municipalities. This strong result holds regardless of which metropolitan region we examined, or which decade. This affirms that municipalities are indeed Tieboutian clubs.
The role of labor discrimination in spatial sorting: the USA as an example of ethnic groups staying apart
Authors: Díaz-Dapena Alberto , Pérez Villadóniga María José 
Published: June 2024

AbstractDespite the vast research about discrimination, there is little evidence about how space interacts with it. Our main hypothesis is that a discriminated group could have incentives to stay together, even if the location is less dynamic—avoiding areas where firms do not usually hire workers of their group. A virtuous and/or vicious circle emerges for each group, even in the long run. Using USA as an example, this article introduces a theoretical economic model to explain the incentives of ethnic groups in terms of location. We extend the well-known model of discrimination with imperfect information to a spatial framework. The results seem to indicate that the initial population distribution and the barriers to agglomerate activity (transport costs), as well as the behavior of employees, are key elements to determine the equilibrium. As a general conclusion, discrimination processes could clearly modify the location pattern of the population. Hence, the discriminated group could suffer from lower incentives to move from non-agglomerated areas to dynamic areas. These processes could help to explain why some populations prefer to maintain their traditional location in poor areas even if there are places with higher wages or better quality of life.
Analysis of highly polar anionic pesticides in food of plant and animal origin by ion chromatography and tandem mass spectrometry with emphasis on addressing adverse effects caused by matrix co-extractives
Authors: Schäfer Ann-Kathrin , Vetter Walter , Anastassiades Michelangelo 
Published: June 2024

AbstractResidues of various highly polar pesticides and their metabolites are commonly found in numerous food products. Some of these compounds, such as glyphosate, are not only used in large amounts in agriculture, but are also controversially discussed in public. Here, we present a method, employing ion chromatography (IC) coupled to tandem mass spectrometry (IC-MS/MS), for the analyses of glyphosate, aminomethyl phosphonic acid (AMPA), N-acetyl-glyphosate (NAGly), fosetyl, and 10 further highly polar pesticides and metabolites in various plant and animal matrices following a minimal sample preparation by means of the QuPPe method. Thorough investigations showed that an AS19 column enabled the analysis of all 14 compounds within 30 min. The best sensitivity could be obtained with the make-up solvent acetonitrile being admixed to the mobile phase at a 1:2 flow rate ratio. Matrix effects were thoroughly studied in terms of ion suppression and retention time shifts. Conductivity detection was used to monitor elution profiles of matrix co-extractives in comparison with matrix effect profiles obtained by continuous post-column infusion of a mix with 13 highly polar pesticides and metabolites. These tests indicated that a fivefold dilution of QuPPe extracts was suitable for the routine analysis of samples for MRL-conformity, as it considerably reduced matrix effects maintaining sufficient sensitivity and high recovery rates in eight different commodities. The suitability of the final method for its application in routine analysis was verified by the analysis of >130 samples containing incurred residues where the results were compared with two existing LC-MS/MS methods.

AbstractGerminomas frequently cause hydrocephalus, and ventriculoperitoneal shunts (VPS) have been commonly used for their management. Although VPS can potentially serve as a route for peritoneal dissemination of germinomas, the abdominal imaging characteristics of this rare yet important complication remain unknown. In this article, we report the computed tomography imaging findings of diffuse peritoneal dissemination of intracranial germinoma.
