AbstractBackgroundTiLOOP bra has been used for over 15 years, however, evidence regarding its safety in implant‐based breast reconstruction (IBBR) for patients with breast cancer after mastectomy is still limited. We performed this meta‐analysis to evaluate its risks and benefits in IBBR comparing with other meshes.MethodsElectronic databases were searched to identify relevant studies comparing postoperative complications between TiLOOP bra and other reconstruction techniques in IBBR with or without meshes. We also compared patient satisfaction in physical well‐being between two groups. Risk ratios (RRs) and mean differences with 95% confidence interval (CI) were calculated.ResultsSeven studies representing 1203 cases were analyzed. Compared with other meshes, the use of TiLOOP bra significantly reduced the risk of infection (RR = 0.53, 95% CI, 0.32–0.86), seroma (RR = 0.21, 95% CI, 0.07–0.61), red breast syndrome (RR = 0.10, 95% CI, 0.02–0.45), and capsular contracture (RR = 0.20, 95% CI, 0.05–0.75). Patient satisfaction in physical well‐being was comparable between two groups.ConclusionsTiLOOP bra in IBBR has a favored safety profile over other meshes, which significantly reduced postoperative complication risk and did not affect patient satisfaction. Although prospective well‐designed controlled studies are still warranted, TiLOOP bra is safe and reliable at present.
Contextualizing (Safety) Rules
Authors: Le Coze Jean-Christophe 
Published: February 2024

AbstractThis introductory chapter combines several dimensions which are meant to help frame a complex topic representing a very rich diversity of situations across industries, countries, and epochs. The idea is to sensitize readers to several aspects associated with the topic of rules and autonomy in the domain of safety, and of this book. Its aim is to emphasize the importance of contexts when it comes to (safety) rules. Contexts refer to organizations, to industries, to risks, to histories, to practices, to situations, and to countries. Three sections develop the importance of context: (1) The advent of safety rules as an established narrative, (2) There is more than rules in safety, and (3) Historical trends … a bureaucratization of safety? The last section presents the chapters of this book, grouped in three categories, (1) Finding or losing the balance; (2) The role, position, and influence of middle-managers and top management, finally; (3) When autonomy, initiative, and resilience take the lead.
Relaxation terms for anomalous hydrodynamic transport in Weyl semimetals from kinetic theory
Authors: Amoretti Andrea , Brattan Daniel K. , Martinoia Luca , Matthaiakakis Ioannis , Rongen Jonas 
Published: February 2024

Abstract
We consider as a model of Weyl semimetal thermoelectric transport a (3 + 1)-dimensional charged, relativistic and relaxed fluid with a U(1)V × U(1)A chiral anomaly. We take into account all possible mixed energy, momentum, electric and chiral charge relaxations, and discover which are compatible with electric charge conservation, Onsager reciprocity and a finite DC conductivity. We find that all relaxations respecting these constraints necessarily render the system open and violate the second law of thermodynamics. We then demonstrate how the relaxations we have found arise from kinetic theory and a modified relaxation time approximation. Our results lead to DC conductivities that differ from those found in the literature opening the path to experimental verification.
Scalar two-point functions at the late-time boundary of de Sitter
Authors: Şengör Gizem , Skordis Constantinos 
Published: February 2024

Abstract
We calculate two-point functions of scalar fields of mass m and their conjugate momenta at the late-time boundary of de Sitter with Bunch-Davies boundary conditions, in general d + 1 spacetime dimensions. We perform the calculation using the wavefunction picture and using canonical quantization. With the latter one clearly sees how the late-time field and conjugate momentum operators are linear combinations of the normalized late-time operators αN and βN that correspond to unitary irreducible representations of the de Sitter group with well-defined inner products. The two-point functions resulting from these two different methods are equal and we find that both the autocorrelations of αN and βN and their cross correlations contribute to the late-time field and conjugate momentum two-point functions. This happens both for light scalars $$ \left(m<\frac{d}{2}H\right) $$

In the special case m = 0, only the βN autocorrelation contributes to the conjugate momentum two-point function in any dimensions and we gather hints that suggest αN to correspond to discrete series representations for this case at d = 3.
Probing CP violation in dark sector through the electron electric dipole moment
Authors: Liu Jia , Nakai Yuichiro , Shigekami Yoshihiro , Song Muyuan 
Published: February 2024

Abstract
The Two Higgs Doublet Model (2HDM) stands as a promising framework for exploring physics beyond the Standard Model (SM). Within this context, we explore the possibility that the two Higgs doublets may serve as a window into CP-violating dark sectors, neutral under the SM gauge groups. Specifically, our focus is on investigating the electric dipole moment (EDM) of the electron, generated solely by CP violation in the dark sector. We present a general formula for the electron EDM, without specifying the structure of the dark sectors, and discuss the current constraints on various dark sector models. It is noteworthy that even in the case of a CP-conserving 2HDM, the resulting electron EDM is capable of reaching the current experimental limit, with CP violation arising exclusively from the dark sectors. Furthermore, we introduce a heavy dark sector (HDS) approximation for the analytic calculation of the EDM, assuming that the dark sector particles are much heavier than the physical states in the 2HDM. This approximation yields simplified analytic results that are consistent with the full numerical calculations.
Finite volume form factors in integrable theories

Published: February 2024

Abstract
We develop a new method to calculate finite size corrections for form factors in two-dimensional integrable quantum field theories. We extract these corrections from the excited state expectation value of bilocal operators in the limit when the operators are far apart. We elaborate the finite size effects explicitly up to the 3rd Lüscher order and conjecture the structure of the general form. We also fully recover the explicitly known massive fermion finite volume form factors.
Lightcone fluctuations in a five dimensional Kaluza-Klein model and an estimation on the size of the extra dimension
Authors: Aleixo Giulia , Mota Herondy 
Published: February 2024

Abstract
In this work we consider lightcone fluctuation effects in a five-dimensional spacetime arising as a consequence of the compactification of the extra dimension via a quasiperiodic condition, characterized by a phase angle 2πα. By considering light propagating in a non-compactified direction we are able to compute both the renormalized graviton two-point function and the flight time of a photon caused by the fluctuations. We show that the resulting expressions depend on the quasiperiodic parameter, the compactification length and also on the distance traveled by the photon. Based on the Near-Infrared Spectrograph (NIRSpec) sensitivity built on the James Webb Space Telescope, we discuss the possibility of making estimations on the size of the extra dimension if one assumes that the mean deviation on the flight time of photons can be observed through the NIRSpec. We also analyze the differences between the estimations in the periodic α = 0, antiperiodic α = 1/2 and other condition cases for α.
Not all nilpotent monoids are finitely related
Authors: Steindl Markus 
Published: February 2024

AbstractA finite semigroup is finitely related (has finite degree) if its term functions are determined by a finite set of finitary relations. For example, it is known that all nilpotent semigroups are finitely related. A nilpotent monoid is a nilpotent semigroup with adjoined identity. We show that every 4-nilpotent monoid is finitely related. We also give an example of a 5-nilpotent monoid that is not finitely related. To our knowledge, this is the first example of a finitely related semigroup where adjoining an identity yields a semigroup which is not finitely related. We also provide examples of finitely related semigroups which have subsemigroups, homomorphic images, and in particular Rees quotients, that are not finitely related.

AbstractExtracellular vesicles (EVs) are important players in melanoma progression, but their use as clinical biomarkers has been limited by the difficulty of profiling blood-derived EV proteins with high depth of coverage, the requirement for large input amounts, and complex protocols. Here, we provide a streamlined and reproducible experimental workflow to identify plasma- and serum- derived EV proteins of healthy donors and melanoma patients using minimal amounts of sample input. SEC–DIA-MS couples size-exclusion chromatography to EV concentration and deep-proteomic profiling using data-independent acquisition. From as little as 200 µL of plasma per patient in a cohort of three healthy donors and six melanoma patients, we identified and quantified 2896 EV-associated proteins, achieving a 3.5-fold increase in depth compared to previously published melanoma studies. To compare the EV-proteome to unenriched blood, we employed an automated workflow to deplete the 14 most abundant proteins from plasma and serum and thereby approximately doubled protein group identifications versus native blood. The EV proteome diverged from corresponding unenriched plasma and serum, and unlike the latter, separated healthy donor and melanoma patient samples. Furthermore, known melanoma markers, such as MCAM, TNC, and TGFBI, were upregulated in melanoma EVs but not in depleted melanoma plasma, highlighting the specific information contained in EVs. Overall, EVs were significantly enriched in intact membrane proteins and proteins related to SNARE protein interactions and T-cell biology. Taken together, we demonstrated the increased sensitivity of an EV-based proteomic workflow that can be easily applied to larger melanoma cohorts and other indications.
On the Automorphism Groups of Certain Branched Structures on Surfaces
Authors: Faraco Gianluca 
Published: February 2024

AbstractWe consider translation surfaces with poles on surfaces. We shall prove that any finite group appears as the automorphism group of some translation surface with poles. As a direct consequence we obtain the existence of structures achieving the maximal possible number of automorphisms allowed by their genus and we finally extend the same results to branched projective structures.
On a mathematical model for cancer invasion with repellent pH-taxis and nonlocal intraspecific interaction
Authors: Eckardt Maria , Surulescu Christina 
Published: February 2024

AbstractStarting from a mesoscopic description of cell migration and intraspecific interactions, we obtain by upscaling an effective reaction–diffusion–taxis equation for the cell population density involving spatial nonlocalities in the source term and biasing its motility and growth behavior according to environmental acidity. We prove global existence, uniqueness, and boundedness of a nonnegative solution to a simplified version of the coupled system describing cell and acidity dynamics. A 1D study of pattern formation is performed. Numerical simulations illustrate the qualitative behavior of solutions.
Non-isomorphism of A∗n,2≤n≤∞, for a non-separable abelian von Neumann algebra A

Published: February 2024

AbstractWe prove that if A is a non-separable abelian tracial von Neuman algebra then its free powers A∗n,2≤n≤∞, are mutually non-isomorphic and with trivial fundamental group, $\mathcal{F}(A^{*n})=1$, whenever 2≤n<∞. This settles the non-separable version of the free group factor problem.
Novel biologically active pyridine derivatives: Synthesis, structure characterization, in vitro antimicrobial evaluation and structure-activity relationship
Authors: Elsayed Mohamed A. , Elsayed Alshaimaa M. , Sroor Farid M. 
Published: February 2024

AbstractThe rate of microbial resistance has continued to rise significantly as the availability of new antibiotics has declined. A new series of pyridine and thienopyridine derivatives were designed, synthesized and tested as antimicrobial agents. The reaction of 4-bromo acetophenone and vetraldehyde (3,4-dimethoxy benzaldehyde) in ethanol and sodium hydroxide solution afforded the corresponding chalcone which was used as a suitable precursor to prepare a new series of pyridine derivatives. The treatment of the latter chalcone with 2-cyanothioacetamide afforded the corresponding pyridinethione which was used as a precursor to synthesize the targeted thienopyridine derivatives in good to excellent yield by the reaction with 2-chloro-N-arylacetamide derivatives, α-haloketones, methyl iodide or chloroacetonitrile in one or two steps. The structure of the synthesized compounds was confirmed chemically by their preparations with other pathways and their spectral data. The newly synthesized pyridine and thienopyridine derivatives exhibited good to strong antimicrobial activity against microbial strains E. coli, B. mycoides and C. albicans. With maximal antimicrobial activity against B. mycoides (33 mm) and C. albicans (29 mm), respectively, compounds 12a and 15 demonstrated the highest inhibition zone. Compound 12a prevented the growth of E. coli, at MIC level of 0.0195 mg/mL, and B. mycoides and C. albicans at MIC level below than 0.0048 mg/mL, respectively. Additionally, compound 15 prevented the visible growth of E. coli, B. mycoides, and C. albicans at MIC values of >0.0048, 0.0098, and 0.039 mg/mL, respectively. The relation between the chemical structure of the synthesized pyridine and thienopyridine compounds and their antimicrobial properties was discussed in the SAR study.

Published: February 2024

Abstract
Purpose
Nutrition is of paramount importance in critically ill trauma patients. However, adequate supply is difficult to achieve, as caloric requirements are unknown. This study investigated caloric requirements over time, based on indirect calorimetry, in critically ill trauma patients.

Methods
Retrospective cohort study at a tertiary trauma center including critically ill trauma patients who underwent indirect calorimetry 2012–2019. Caloric requirements were assessed as resting energy expenditure (REE) during the intensive care unit stay up to 28 days and analyzed in patient-clustered linear regression analysis.

Results
A total of 129 patients were included. Median REE per day was 2376 kcal. The caloric intake did not meet REE at any time with a median daily deficit of 1167 kcal. In univariable analysis, ISS was not significantly associated with REE over time (RC 0.03, p = 0.600). Multivariable analysis revealed a significant REE increase (RC 0.62, p < 0.001) and subsequent decrease (RC – 0.03, p < 0.001) over time. Age < 65 years (RC 2.07, p = 0.018), male sex (RC 4.38, p < 0.001), and BMI ≥ 35 kg/m2 (RC 6.94, p < 0.001) were identified as independent predictors for higher REE over time. Severe head trauma was associated with lower REE over time (RC – 2.10, p = 0.030).

Conclusion
In critically ill trauma patients, caloric requirements significantly increased and subsequently decreased over time. Younger age, male sex and higher BMI were identified as independent predictors for higher caloric requirements, whereas severe head trauma was associated with lower caloric requirements over time. These results support the use of IC and will help to adjust nutritional support in critically ill trauma patients.
Abschluss statt Ausschluss – die klinische Diagnosesicherung funktioneller Bewegungsstörungen
Authors: Weissbach Anne , Bolte Christina , Münchau Alexander 
Published: February 2024

ZusammenfassungFunktionelle neurologische Bewegungsstörungen sind in der neurologischen Praxis häufig und führen zu einer hohen Beeinträchtigung und Chronifizierung. Betroffene erhalten meist erst mit langer Latenz eine Diagnose und häufig keine krankheitsspezifische Therapie. Eine Ursache dieser Verzögerung ist die häufig im Vorfeld durchgeführte umfangreiche apparative Diagnostik, die meist vorrangig dem Ausschluss anderer neurologischer Erkrankungen dient. Diese unauffällige Diagnostik wird dann häufig genutzt, um die funktionelle Bewegungsstörung als Ausschlussdiagnose zu kommunizieren. Patienten fällt es dadurch schwer, die Diagnose zu verstehen und anzunehmen. Dies ist besonders bedauerlich, da bei einem Großteil der Patienten die Diagnose sicher anhand der klinischen Charakteristika – Inkonsistenz und Inkongruenz – zu stellen ist. Die Erklärung der Symptome und die sich daraus ergebenden Therapieoptionen sollten zudem um patientengerechte Erläuterungen der pathophysiologischen Grundlagen der Erkrankung ergänzt werden. Die Patienten werden dadurch befähigt, die Diagnose einer funktionellen Bewegungsstörung ganzheitlich zu verstehen und zu akzeptieren. Dies kann wiederum die zum Teil jahrzehntelang andauernde Suche nach einer Diagnose zu einem Abschluss bringen, was den Weg in die Therapie ebnet. Die „Abschlussdiagnose“ wird damit zu einem Startpunkt der Behandlung und kann an sich bereits therapeutisch wirksam sein.
Effect of fluorine doping on the improvement of electrical and photocatalytic properties of ZnO films
Authors: Karakaya Seniye , Kaba Leyla 
Published: February 2024

AbstractZnO:F thin films were produced by ultrasonic spray pyrolysis (USP) technique. For photovoltaic and photocatalytic applications, the properties of ZnO films have been tried to be improved by adding the flourine (F) element. The average optical transmittance was higher than 85%. Photoluminescence (PL) spectra depict blue, green and yellow emission in deposited films. Photocatalytic activity of ZnO and ZnO:F thin films was evaluated with methylene blue (MB) organic pollutant under UV irradiation. 5% doped ZnO:F film successfully decomposed ~ 80% using MB as photocatalyst. The lowest resistivity (3.54 × 10–3 Ωcm), high carrier concentration (2.52 × 1020 cm−3) and high hall mobility (8.28 cm2V−1 s−1) were observed in ZnO:F (5%) film. With this study, it was concluded that F-doped ZnO films were effective in the degradation of MB, which is widely used in the food and pollutant industries. Therefore, it makes ZnO:F films a promising material in both optoelectronic and photocatalytic applications due to their optimum properties.

AbstractThe amyloid cascade hypothesis states that Aβ aggregates induce pathological changes in tau, leading to neurofibrillary tangles (NFTs) and cell death. A caveat with this hypothesis is the spatio-temporal divide between plaques and NFTs. This has been addressed by the inclusion of soluble Aβ and tau species in the revised amyloid cascade hypothesis. Nevertheless, despite the potential for non-plaque Aβ to contribute to tau pathology, few studies have examined relative correlative strengths between total Aβ, plaque Aβ and intracellular Aβ with tau pathology within a single tissue cohort. Employing frozen and fixed frontal cortex grey and white matter tissue from non-AD controls (Con; n = 39) and Alzheimer’s disease (AD) cases (n = 21), biochemical and immunohistochemical (IHC) measures of Aβ and AT-8 phosphorylated tau were assessed. Biochemical native-state dot blots from crude tissue lysates demonstrated robust correlations between total Aβ and AT-8 tau, when considered as a combined cohort (Con and AD) and when as Con and AD cases, separately. In contrast, no associations between Aβ plaques and AT-8 were reported when using IHC measurements in either Con or AD cases. However, when intracellular Aβ was measured via the Aβ specific antibody MOAB-2, a correlative relationship with AT-8 tau was reported in non-AD controls but not in AD cases. Collectively the data suggests that accumulating intracellular Aβ may influence AT-8 pathology, early in AD-related neuropathological change. Despite the lower levels of phospho-tau and Aβ in controls, the robust correlative relationships observed suggest a physiological association of Aβ production and tau phosphorylation, which may be modified during disease. This study is supportive of a revised amyloid cascade hypothesis and demonstrates regional associative relationships between tau pathology and intracellular Aβ, but not extracellular Aβ plaques.
Stacked multi-wedge acoustic black holes for low-frequency attenuation of flexible beams
Authors: Käfer Max , Dohnal Fadi 
Published: February 2024

Abstract
Machines and other driving components like compressors or fans usually generate vibrations which frequently lead to acoustic noise. Flexible structures equipped with acoustic black holes minimise acoustic radiation by confining structural vibrations locally. One main restriction of its usage in the broad engineering field is its limited effectiveness at low frequencies. Recent investigations shifted the frequency range of attenuation successfully down to 1500 Hz. Moving the existing designs towards an even lower frequency demands a large structure. However, in general, sufficient space is often not available in machines and facilities. We propose a new design that enables a geometrically compact and simultaneously broadband vibration attenuation in the low-frequency below to 100 Hz: stacked wedges. The proposed design is calculated and optimised numerically by combining CAD and finite element calculations. The influence of geometrical parameters on the effectiveness of vibration attenuation is analysed with the help of transfer functions and dispersion curves. Successful designs of multi-stacked wedges at different lengths confirm their effectiveness at low frequency.
