Demolition(s) in Question: A Pedagogical Approach Case Study: Toulouse Le Mirail
Authors: Concheiro Guisan Isabel 
Published: October 2024

AbstractThe transformation of non-heritage protected mid-twentieth century European architecture, especially public housing, is a key contemporary issue that raises several architectural, environmental and social questions. While several examples show the potential for transformation, demolition is unfortunately still considered commonplace, leading not only to the loss of architectural heritage and affordable housing, but also to the destruction of communities built over decades. In this context, architects have an important role to play in proposing alternatives. Within the framework of architectural schools, and in addition to design-based strategies, it seems necessary to confront students as well with a critical analysis of complex demolition processes in theoretical courses. The course “Transformation Strategies” at the HEIA-FR proposes collective research aimed at questioning demolition processes, and at developing a sensitive approach and methodology to reveal architectural, environmental and social values as a basis for the transformation of mid-twentieth century architecture. The first case study aims to question the ongoing demolition process in the Toulouse Le Mirail district, designed by Candilis, Josić and Woods in the 1960s.
Soft limits of gluon and graviton correlators in Anti-de Sitter space
Authors: Chowdhury Chandramouli , Lipstein Arthur , Mei Jiajie , Mo Yuyu 
Published: October 2024

Abstract
We derive formulae for the soft limit of tree-level gluon and graviton correlators in Anti-de Sitter space, which arise from Feynman diagrams encoding the Weinberg soft theorems in flat space. Other types of diagrams can also contribute to the soft limit at leading order in the soft momentum, but have a different pole structure. We derive these results at four points using explicit formulae recently obtained from the cosmological bootstrap and double copy, and extend them to any multiplicity using bootstrap techniques in Mellin-momentum space.
Non-spinning tops are stable
Authors: Bena Iosif , Di Russo Giorgio , Morales Jose Francisco , Ruipérez Alejandro 
Published: October 2024

Abstract
We consider coupled gravitational and electromagnetic perturbations of a family of five-dimensional Einstein-Maxwell solutions that describes both magnetized black strings and horizonless topological stars. We find that the odd perturbations of this background lead to a master equation with five Fuchsian singularities and compute its quasinormal mode spectrum using three independent methods: Leaver, WKB and numerical integration. Our analysis confirms that odd perturbations always decay in time, while spherically symmetric even perturbations may exhibit for certain ranges of the magnetic fluxes instabilities of Gregory-Laflamme type for black strings and of Gross-Perry-Yaffe type for topological stars. This constitutes evidence that topological stars and black strings are classically stable in a finite domain of their parameter space.

Integrability in gravity from Chern-Simons theory
Authors: Cole Lewis T. , Weck Peter 
Published: October 2024

Abstract
This paper presents a new perspective on integrability in theories of gravity. We show how the stationary, axisymmetric sector of General Relativity can be described by the boundary dynamics of a four-dimensional Chern-Simons theory. This approach shows promise for simplifying solution generating methods in both General Relativity and higher-dimensional supergravity theories. The four-dimensional Chern-Simons theory presented generalises those for flat space integrable models by introducing a space-time dependent branch cut in the spectral plane. We also make contact with twistor space approaches to integrability, showing how the branch cut defects of four-dimensional Chern-Simons theory arise from a discrete reduction of six-dimensional Chern-Simons theory.
Low energy limit from high energy expansion in mass gapped theory
Authors: Takaura Hiromasa 
Published: October 2024

Abstract
We present a method to extract the low energy behavior of physical observables from their high energy expansions, systematically calculable via the operator product expansion (OPE), in asymptotically free and mass-gapped theories. By applying the inverse Laplace transform to correlation functions, their analytic structure is modified such that low-energy information connects with high energy expansions. Furthermore, this transformation alleviates the renormalon problem, enabling a more straightforward application of the OPE compared to the OPE before the transformation. We demonstrate that the low energy limit of correlation functions can be accurately extracted using the OPE in the two dimensional O(N) nonlinear σ model, serving as a first testing ground.
Prospect of measuring the top quark mass through energy correlators
Authors: Xiao Meng , Ye Yulei , Zhu Xinyu 
Published: October 2024

Abstract
Reaching a high precision of the top quark mass is an important task of the Large Hadron Collider. We perform a feasibility study of measuring the top quark mass through the three-point energy correlator. The expected sensitivity of the top quark mass in the boosted regime is presented. We further introduce its application to the low top pT regime and demonstrate that both the W boson and the top quark masses could be extracted from this single observable. Compared to traditional observables, the energy correlator shows robustness to uncertainties that usually dominate experimental measurements and provides a promising way to improve experimental precision.
Relativity of the event: examples in JT gravity and linearized GR
Authors: Nitti Francesco , Piazza Federico , Taskov Alexander 
Published: October 2024

Abstract
Observables in quantum gravity are famously defined asymptotically, at the boundary of AdS or Minkowski spaces. However, by gauge fixing a coordinate system or suitably dressing the field operators, an approximate, “quasi-local” approach is also possible, that can give account of the measurements performed by a set of observers living inside the spacetime. In particular, one can attach spatial coordinates to the worldlines of these observers and use their proper times as a time coordinate. Here we highlight that any such local formulation has to face the relativity of the event, in that changing frame (= set of observers) implies a reshuffling of the point-events and the way they are identified. As a consequence, coordinate transformations between different frames become probabilistic in quantum gravity. We give a concrete realization of this mechanism in Jackiw-Teitelboim gravity, where a point in the bulk can be defined operationally with geodesics anchored to the boundary. We describe different ways to do so, each corresponding to a different frame, and compute the variances of the transformations relating some of these frames. In particular, we compute the variance of the location of the black hole horizon, which appears smeared in most frames. We then suggest how to calculate this effect in Einstein gravity, assuming knowledge of the wavefunction of the metric. The idea is to expand the latter on a basis of semiclassical states. Each element of this basis enjoys standard/deterministic coordinate transformations and the result is thus obtained by superposition. As a divertissement, we sabotage Lorentz boosts by adding to Minkoswki space a quantum superposition of gravitational waves and compute the probabilistic coordinate transformation to a boosted frame at linear order. Finally, we attempt to translate the relativity of the event into the language of dressed operators.
A perturbative approach to the non-relativistic string spectrum
Authors: de Leeuw Marius , Fontanella Andrea , García Juan Miguel Nieto 
Published: October 2024

Abstract
In this letter we use a perturbative approach to find the spectrum of non-relativistic strings in the String Newton-Cartan (SNC) AdS5×S5 spacetime. We perturb the bosonic sector of the action around a BMN-like folded string solution in light-cone gauge. We find strong evidence that the theory is described by a combination of massive and massless free fields in an anti-de Sitter background by showing that interaction terms up to six scalars vanish after field redefinitions.
Parabolic logistic equation with harvesting involving the fractional Laplacian
Authors: Chhetri Maya , Girg Petr , Hollifield Elliott , Kotrla Lukáš 
Published: October 2024

AbstractThis paper deals with a class of parabolic reaction-diffusion equations driven by the fractional Laplacian as the diffusion operator over a bounded domain with zero Dirichlet external condition. Using a comparison principle and monotone iteration method, we establish existence and uniqueness results. We apply the existence result to the logistic growth problems with constant yield harvesting by constructing an ordered pair of positive sub- and supersolution of the corresponding elliptic problem.

ZusammenfassungKardiovaskuläre Risikofaktoren (Bluthochdruck, Rauchen, Übergewicht, Diabetes mellitus Typ 2, Dyslipidämie, körperliche Inaktivität) steigen mit zunehmendem Alter, insbesondere ab dem mittleren Erwachsenenalter, deutlich an, wobei Frauen wesentlich stärker betroffen sind. In der Bevölkerung Sachsen-Anhalts ist die Prävalenz kardiovaskulärer Risikofaktoren stark erhöht, und die Bevölkerungsstruktur in Sachsen-Anhalt ist besonders geprägt von einem hohen Durchschnittsalter sowie einer hohen Morbiditäts- und Mortalitätsrate aufgrund von kardiovaskulären Erkrankungen. Somit bietet Sachsen-Anhalt einen Modellcharakter für die demografische Entwicklung in Europa. Dieser Übersichtsbeitrag thematisiert Strategien zur Umsetzung zielgruppenspezifischer, kardiovaskulärer Präventionsstrategien im Bundesland Sachsen-Anhalt unter besonderer Berücksichtigung von Alter und Geschlecht. Indem präventivmedizinische Einrichtungen aufgebaut und innovative Versorgungsmöglichkeiten für kardiovaskuläre Risikopatienten geschaffen werden, soll Prävention auch dem ländlichen Bereich zugänglich gemacht werden.
Strong and weak AI narratives: an analytical framework
Authors: Bory Paolo , Natale Simone , Katzenbach Christian 
Published: October 2024

AbstractThe current debate on artificial intelligence (AI) tends to associate AI imaginaries with the vision of a future technology capable of emulating or surpassing human intelligence. This article advocates for a more nuanced analysis of AI imaginaries, distinguishing “strong AI narratives,” i.e., narratives that envision futurable AI technologies that are virtually indistinguishable from humans, from "weak" AI narratives, i.e., narratives that discuss and make sense of the functioning and implications of existing AI technologies. Drawing on the academic literature on AI narratives and imaginaries and examining examples drawn from the debate on Large Language Models and public policy, we underscore the critical role and interplay of weak and strong AI across public/private and fictional/non-fictional discourses. The resulting analytical framework aims to empower approaches that are more sensitive to the heterogeneity of AI narratives while also advocating normalising AI narratives, i.e., positioning weak AI narratives more firmly at the center stage of public debates about emerging technologies.
Influences of ion bombardment, grain size, and gamma irradiation on surface topography, microstructural, and mechanical characteristics of Cu-2 wt% Sb alloy
Authors: Soliman H. N. , Sobhy M. 
Published: October 2024

AbstractThe Cu-2 wt% Sb alloy was prepared and exposed to various heat treatments at temperatures ranging from 573 to 973 K to get distinct grain diameters. Different samples of various grain diameters were individually sputtered in an argon glow discharge for various times (0.5, 1, 2 h) using a DC magnetron sputtering device. The surface topography and microstructural features of a Cu-2 wt% Sb alloy were examined utilizing an optical microscopy (OM), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), and X-ray diffraction (XRD). The $$Cu_{3} Sb$$

IMC phase was found to segregate at the grain boundaries. Results showed that the topographical features of sputtered samples (grain boundaries, tiny cones, cratered cones, and etch pits) were mainly affected by grain size and sputtering time. Moreover, the mechanical properties of a Cu-2 wt% Sb alloy were examined. The parameters of the stress–strain curves (Young modulus Y, 0.2% offset stress σy0.2, fracture stress σf, parabolic work-hardening coefficient $${\upchi }_{{\text{p}}}$$

decreases as the strain rate increases. Additionally, selective samples of the present alloy were irradiated using γ-radiation with different doses 0.5, 1, 1.5, and 2 MGy. The Vickers microhardness of annealed and irradiated samples lowered as the grain size augmented, while it increased as the irradiation dose increased. Based on the obtained activation energy Q value of 20.65 kJ/mol., it is indicated that the predominant deformation mechanism in the Cu-2 wt% Sb alloy is the motion of dislocation through the Cu-matrix.

AbstractIntermittent theta burst stimulation (iTBS), a variant of repetitive transcranial magnetic stimulation (rTMS), is an established treatment for adults with major depressive disorder (MDD). Due to its favorable safety profile, iTBS is also a promising early intervention in the transition phase from adolescence to early adulthood, but this has not been systematically investigated to date. Thus, the EARLY-BURST trial investigates the efficacy and safety of iTBS over the left dorsolateral prefrontal cortex (lDLPFC) in treatment-seeking young patients (age 16–26 years) with depressive disorders (i.e. major depressive disorder, persistent depressive disorder, bipolar depression), allowing for relevant co-morbidities. Participants have not received antidepressant or antipsychotic medication during the last 12 months except for short-term (< 2 weeks) on-demand medication. The trial will employ a novel sequential Bayesian, randomized, double-blind, parallel-group, sham-controlled design. Up to 90 patients at two clinical sites (Munich, Augsburg) will be randomized 1:1 to the treatment groups, with sequential analyses starting after 26 patients in each group completed the treatment. The primary outcome will be the difference in depression severity at week 6 (post-treatment visit) between active iTBS and sham iTBS, assessed with the Montgomery-Åsberg Depression Rating Scale (MADRS). The trial is planned to be expanded towards a three-arm leapfrog design, contingent on securing additional funding. Thus, in addition to potentially providing evidence of iTBS’s efficacy in adolescents and young adults with depressive disorders, the EARLY-BURST trial aims at setting the stage for subsequent platform trials in this dynamic research field, where novel adaptive study designs are required to meet the need for rapidly testing promising new vs established rTMS protocols.Trial registration: DRKS00033313.
Apraxia phenotypes and frontotemporal lobar degeneration
Authors: Langheinrich Tobias C. , Thompson Jennifer C. , Jones Matthew , Richardson Anna M. T. , Mann David M. A. , Snowden Julie S. 
Published: October 2024

Abstract
Background
Apraxia has been identified in all clinical forms of frontotemporal lobar degeneration (FTLD). The characteristics of apraxia symptoms and their underlying cognitive/motor basis are not fully understood. This study investigated apraxia in pathological subtypes of FTLD.

Methods
The study constituted a retrospective review of 115 pathologically confirmed cases of FTLD from a single cognitive neurology centre. Patients in whom apraxia had been documented as a notable clinical characteristic were identified. Apraxia features, demographic, cognitive, neurological, and imaging findings were recorded.

Results
Eighteen patients were identified: 12 with FTLD-tau pathology (7 corticobasal degeneration (CBD), four Pick type and one progressive supranuclear palsy (PSP)) and six with FTLD-TDP pathology, all type A and four linked to progranulin gene mutations. Apraxia as a dominant presenting feature was typically associated with tau pathologies, whereas it emerged in the context of aphasia in TDP pathology. Apraxia typically predominated in one body part (face or limb) in tau but not TDP pathology. Relatively preserved activities in daily life were associated with TDP. Apraxia of speech was associated with tau pathology. Pick-type pathology was linked to symmetrical atrophy and late development of limb rigidity.

Conclusion
Apraxia in FTLD subtypes has variable characteristics. Apraxia associated with CBD pathology conformed to criteria for probable corticobasal syndrome (CBS), whereas apraxia with Pick-type pathology did not. Apraxia in patients with TDP-A pathology was interpreted as one manifestation of their generalised communication disorder. Apraxia in FTLD may have distinct cognitive and motor substrates that require prospective investigation.

Published: October 2024

Abstract
Background
Malnutrition is a significant risk for patients during cancer treatment. Neglecting to monitor or provide timely dietetic support can result in lower tolerance to treatments and reduced quality of life. This audit aimed to assess the completeness and accuracy of the documentation of anthropometric measurements in medical records and dietetic referral practices across four day-treatment units (DTUs) in England.

Methodology
Data were collected from electronic patient records of 100 patients in each DTU attending for systemic anti-cancer treatment (SACT) over a 2-week period. Data collected included patients’ demographics, anthropometric data, referrals to dietitians, and whether the patients referred had a MUST score ≥ 2, which was calculated by the authors.

Results
Findings revealed that weights and heights were documented for 58–85% and 94–98% of patients attending DTUs, respectively. On average, 55% (range of 7–85%) of patients had their body mass index (BMI) documented on the day of SACT. The Malnutrition Universal Screening Tool (MUST) was rarely completed (≤ 3% in each centre). Dietetic referral practices varied across centres.

Conclusions
Findings highlight the need to improve anthropometric documentation practices in cancer centres, in order to allow better monitoring of malnutrition risk and early nutritional support interventions when needed.
Gehirntumoren im Kindesalter – Beitrag der Psychiatrie
Authors: Schönthaler Elena , Jobs Leandra , Roider Sandra , Sator Bianca , Aigner Martin 
Published: October 2024

ZusammenfassungPädiatrische Gehirntumoren stellen die häufigsten soliden Neoplasmen und eine bedeutende Todesursache im Kindesalter dar, wobei moderne Behandlungsmethoden die Überlebensraten einiger Tumorarten erheblich verbessert haben. Die aktuelle Forschung zeigt, dass Überlebende von Gehirntumoren im Kindesalter ein erhöhtes Risiko für somatische und psychische Erkrankungen sowie neurokognitive Beeinträchtigungen im Erwachsenenalter aufweisen. Da ein substanzieller Teil dieser Personengruppe von maßgeblichen Beeinträchtigungen durch psychische Folgeerscheinungen betroffen ist, werden konkrete Behandlungsvorgaben und Empfehlungen für die psychiatrische Praxis benötigt.Der vorliegende Fallbericht beschreibt eine 18-jährige Patientin, die nach der Operation eines pilozytischen Astrozytoms im frühen Kindesalter aufgrund mehrerer psychiatrischer Erkrankungen in einer psychiatrischen Klinik behandelt wurde. Die neuropsychologische Evaluation ergab kognitive Defizite, vorrangig in den Bereichen Verarbeitungsgeschwindigkeit und Sprache. Die Behandlung umfasste psychiatrische Medikationseinstellung, psychotherapeutische Interventionen und sozialarbeiterische Unterstützung. Dieser Fallbericht unterstreicht die Notwendigkeit eines interdisziplinären, biopsychosozialen Ansatzes in der Betreuung von Überlebenden pädiatrischer Gehirntumoren, einschließlich regelmäßiger neuropsychologischer Diagnostik und gezielter kognitiver Förderung. Vor allem bei Gehirntumoren im Kindesalter soll bei späteren psychiatrischen Symptomen auf die komplexe Wechselwirkung zwischen biologischen und psychosozialen Faktoren geachtet werden.
