Generalized nash fairness solutions for bi‐objective minimization problems
Authors: Nguyen Minh Hieu , Baiou Mourad , Nguyen Viet Hung , Vo Thi Quynh Trang 
Published: September 2023

AbstractIn this article, we consider a particular case of bi‐objective optimization (BOO), calledbi‐objective minimization(BOM), where the two objective functions to be minimized take only positive values. As well as for BOO, most of the methods proposed in the literature for solving BOM focus on computing the Pareto‐optimal solutions representing different trade‐offs between two objectives. However, it may be difficult for a central decision‐maker to determine the preferred solutions due to the huge number of solutions in the Pareto set. We propose a novel criterion for selecting the preferred Pareto‐optimal solutions by introducing the concept of ‐Nash Fairness(‐) solutions inspired by the definition of proportional fairness. The ‐ solutions are the feasible solutions achieving some proportional nash equilibrium between the two objectives. The positive parameter is introduced to reflect the relative importance of the first objective to the second one. For this work, we will discuss existential and algorithmic questions about the ‐ solutions by first showing their existence for BOM. Furthermore, the ‐ solution set can be a strict subset of the Pareto set. As there are possibly many ‐ solutions, we focus on extreme ‐ solutions achieving the smallest values for one of the objectives. Then, we propose two Newton‐based iterative algorithms for finding extreme ‐ solutions. Finally, we present computational results on some instances of the bi‐objective travelling salesman problem (BOTSP) and the bi‐objective shortest path problem.

Published: September 2023

AbstractIn this study, we conducted a comprehensive experimental campaign aimed at controlling the final properties of 3D printed cellulose acetate. We equipped a commercial printer with a peristaltic pump to be able to print in a continuous fashion by means of the Direct Ink Writing technique. We investigated the effect of ink concentration and printing parameters on the density, mechanical and functional properties of printed objects. Furthermore, water absorption tests demonstrated the hygroscopic behavior of cellulose acetate, with higher water content in samples with lower densities. The diffusion of water within the polymer network followed Fickian diffusion, with the diffusion coefficient influenced by the density of samples. Overall, this study highlights the importance of printing conditions in achieving desired properties in 3D printed cellulose acetate. The ability to fine‐tune the mechanical properties and water absorbance of 3D printed cellulose acetate makes it promising for applications in plant science and bioengineering.Highlights
Cellulose acetate has been 3D printed via Direct Ink Writing.
The shear‐thinning behavior allows for shape retention during printing.
Density of printed samples is strongly controlled by printing parameters.
Density of printed parts influences mechanical properties and water absorption.

Published: September 2023

AbstractTo improve the adhesive performance of epoxy, some modification was conducted for pure epoxy. First, the models of physical blending of polyimide (PI) and graphene sheet (GNS), as well as polyimide (PI) grafted graphene oxide (GO) modified epoxy resin, were established using molecular dynamics (MD) simulations, along with pure epoxy resin, aiming to thoroughly investigate the effects of these two types of modification on the mechanical, thermal properties and adhesive properties of the epoxy resin. Importantly, three‐layer adhesive models of Cu‐epoxy‐Cu were constructed, and the tensile simulation was carried out to explore the influence of the two modifications on the adhesion strength. The dynamic evolution process and micro information in the tensile process was observed and extracted to reveal the strengthening mechanism of PI grafted GO modified epoxy resin from nano‐scale. The study showed that the epoxy resin modified with PI grafted GO has better mechanical and adhesive properties compared with PI‐GNS blending. The glass transition temperature (Tg) of PI grafted GO was increased by 40 K and the thermal conductivity was increased by 0.16 W/(m·K). This study provided the theoretical guidance for enhancing adhesive strength of epoxy resin.Highlights
Three‐dimensional crosslinked model of epoxy resin was constructed.

A review on shape‐memory polyurethane nanocomposites: Focusing on the most important used nanofillers
Authors: Mohammadzadeh Koumleh Sanaz , Khoubi‐Arani Zahra , Rahmani Shahrzad 
Published: September 2023

AbstractOver recent decades, great steps have been taken to study the shape‐memory polymer nanocomposites and their valuable applications by researchers. Considering the unique and distinguished applications of these materials and based on the fact that polyurethane is one of the most important shape‐memory polymers, there is still a need to publish papers associated with shape memory polyurethane nanocomposites. Despite several recent review papers related to the shape memory polyurethane nanocomposites, a specific review on the shape memory polyurethane nanocomposites that can cover the most important nanofillers used to prepare them is still lacking. This review paper not only classifies the reported studies related to the shape memory polyurethane nanocomposites either alone or with other polymers based on their nanofillers, but also has tried to find a connection between their actuation technique, nanofillers, and their applications.Highlights
Recent developments in shape memory polyurethane nanocomposites were epitomized.
Reported studies were classified based on the most important used nanofillers.
A connection between the used nanofillers and applications was conceptualized.
Generalized linear model based gamma control chart
Authors: Ali Sajid , Asghar Maria , Shah Ismail 
Published: September 2023

AbstractTraditional monitoring techniques are frequently used for monitoring a response variable, while ignoring the other important variables. A simple linear regression model to introduce covariates‐based charts has received a lot of attention in the recent publications. When the response variable belongs to the exponential family, the generalized linear model (GLM) is a flexible approach to model a phenomenon. This study uses gamma distribution to introduce GLM‐based Shewhart‐type control charts. The monitoring statistic is developed using the Pearson residuals (PRs) obtained from the gamma regression model. The suggested charts' performance is evaluated using the run‐length properties and extensive Monte Carlo simulations. A comparison of Pearson‐residual to the deviance‐residual charts is also discussed in this article. Finally, to emphasize the significance of the study, the proposed control charts are implemented on a real‐life data set.

Published: September 2023

AbstractWireless Mesh Networks are considered as a promising solution for offering low‐cost access to broadband services. However, one of the main challenges in the design of these networks is their vulnerability to security attacks. In this paper, we analyze the fundamental security challenges and constraints of these networks, classify several possible attacks, and survey several intrusion prevention, detection, and response mechanisms found in the literature.

Guidelines for Seismic Retrofitting of Earthen Historic Buildings in Peru and Latin America
Authors: Macchioni Elena , Cancino Claudia 
Published: September 2023

AbstractThe development of guidelines for seismic retrofitting of earthen architectural heritage has been part of the intended outputs of the Seismic Retrofitting Project – a partnership between Getty Conservation Institute and the Ministry of Culture of Peru – since its inception. The results of the Seismic Retrofitting Project are currently being reframed to become part of a document written by the Ministry of Culture of Peru, with the support of Getty Conservation Institute staff and consultants, that will guide in the structural analysis, diagnosis, and design of effective structural interventions to conserve earthen constructions and transmit their significance. The document will advise local practitioners, ease their collaboration with the Ministry of Culture of Peru, and possibly become part of the Peruvian regulatory framework, with a broader impact in Latin America. This contribution describes the methodology to collaboratively create the guidelines, ensure their dissemination in the region, and the results obtained to date.
Nebenwirkungen nach Immuncheckpointinhibitortherapie
Authors: Buchtele Nina , Knaus Hanna , Schellongowski Peter 
Published: September 2023

ZusammenfassungImmuntherapien, und insbesondere Immuncheckpointinhibitoren, haben die Behandlung maligner Erkrankungen revolutioniert. Ihrem Wirkmechanismus geschuldet, der Aktivierung körpereigener T‑Zellen, sind jedoch auch häufig Nebenwirkungen die Folge einer Therapie. Sogenannte immunmediierte Nebenwirkungen („immune-related adverse event“, irAE) manifestieren sich als autoimmunologische Phänomene, können in jedem Organsystem auftreten und bis hin zu schwerem Organversagen führen. Aufgrund der zeitlichen Latenz von bis zu Monaten nach Verabreichung eines Checkpointinhibitors bis zur Erstmanifestation einer irAE ist es essenziell, bei entsprechender stattgehabter Therapie zu jedem Zeitpunkt an eine therapiespezifische Nebenwirkung zu denken. Bei beginnendem Organversagen ist das Absetzen des Checkpointinhibitors sowie der rasche Beginn mit einer Hochdosiskortisontherapie essenziell, die bei fehlendem Ansprechen um weitere Immunsuppressiva oder antiinflammatorische Therapieoptionen erweitert werden soll. Generell ist das Ansprechen auf Kortikosteroide und erweiterte Therapieoptionen gut und in diesem Sinne das Organversagen auch oft reversibel. Eine intensivmedizinische Betreuung mit etwaiger Notwendigkeit organunterstützender Therapien sollte dennoch nur streng nach Patient:innenwunsch sowie in enger Rücksprache mit den betreuenden Hämatoonkolog:innen erfolgen. Mit dem großen therapeutischen Nutzen, der häufigen Verwendung und dem vorhandenen Potenzial, in womöglich zukünftig auch kurativen Therapielinien zum Einsatz zu kommen, werden auch Intensivmediziner:innen häufiger mit irAEs nach Checkpointinhibitoren konfrontiert sein. Dementsprechend ist das Verstehen, Erkennen und Therapieren von Nebenwirkungen nach Immuntherapien zunehmend essenziell.
Prevalence and predictors of admission at the time of presentation in first episode psychosis
Authors: Gannon Louisa , Mullen Eddie , McGorry Patrick , O’Donoghue Brian 
Published: September 2023

Abstract
Background
Individuals presenting with first episode psychosis (FEP) constitute a population with high admission rates. Across psychiatric services, community based treatment is aimed for where appropriate. Therefore, further knowledge on predictors of admission is required.

Purpose
The objectives were to: (i) determine the proportion of individuals with FEP admitted at time of presentation (voluntarily and involuntarily) (ii) identify associated demographic and clinical factors.

Methods
This study included all young people (aged 15–24) who presented with FEP to the Early Psychosis Prevention and Intervention Centre, Melbourne, Australia from 01.01.11 to 31.12.16. Binary logistic regression was used to determine unadjusted and adjusted odds ratios.

Results
Of 1208 participants, 58.6% were male and the median age was 20 years (I.Q.R.17–22). At time of presentation, 50.2% were admitted. On multivariate analysis, the following factors predicted admission: being a migrant (OR = 1.75, 95% CI [1.17, 2.62]), aggression (OR = 1.42, 95% CI [1.02, 1.99]), and more severe psychotic symptoms. Longer duration of untreated psychosis was associated with lower admission rates. 70.1% of admissions were involuntary (33.7% of the cohort). Risk factors for involuntary admission were consistent with any admission, other than aggression, and with the addition of older age and male sex.

Conclusion
There remains a high admission rate for FEP, even in an established early intervention service, with severity of psychopathology being the strongest predictive factor. There is an independent association between migrancy and admission. Potential reasons for these findings are discussed, and initiatives to reduce admission rates including (i) interventions to prevent admission and (ii) alternative care pathways.
Langzeitverlauf von makulären Neovaskularisationen bei chorioidalen Osteomen mit und ohne intravitreale Anti-VEGF(vascular endothelial growth factor)-Therapie
Authors: Dütsch M. , Helbig H. , Gamulescu M.-A. , Barth T. 
Published: September 2023

Zusammenfassung
Hintergrund
Das chorioidale Osteom (CO) ist ein benigner knöcherner Aderhauttumor, der überwiegend unilateral auftritt. CO sind potenziell visusbedrohend, insbesondere bei Auftreten sekundärer makulärer Neovaskularisationen (MNV).

Ziel der Arbeit
Anhand einer Fallserie von Patienten mit CO-assoziierter MNV wird die klinische Variabilität des Verlaufs ohne und mit intravitrealer Anti-VEGF(„vascular endothelial growth factor“)-Therapie dargestellt.

Methoden
Bei allen Patienten, bei denen im Zeitraum von 2007 bis 2023 ein CO mit MNV diagnostiziert wurde, erfolgte eine retrospektive Auswertung des klinischen Verlaufs.

Ergebnisse
Es wurde bei 7 Augen von 5 Patienten (4 Frauen, 1 Mann) eine CO-assoziierte MNV diagnostiziert. Eine intravitreale Anti-VEGF-Therapie erfolgte bei 2 Patienten mit einseitiger MNV, ein Fall mit bilateraler MNV wurde beidseits behandelt. In einem weiteren Fall mit beidseitiger MNV wurde nur 1 Auge behandelt, da das Partnerauge eine Fibrose aufwies. Ein weiterer Fall mit einseitigem CO und MNV-Narbe bei Erstdiagnose wurde nicht therapiert. Insgesamt konnte bei 3 der 5 behandelten Augen durch die intravitreale VEGF-Inhibition eine Visusstabilisierung oder Verbesserung erreicht werden.

Diskussion
Die Therapie mit intravitrealen Anti-VEGF-Präparaten bewirkte in unserer Serie bei 3 der 5 behandelten Augen eine funktionelle Stabilisierung oder Verbesserung. Ein Auge mit CO-assoziierter MNV entwickelte ohne Therapie sehr rasch eine Fibrose. Die Aufklärung von Patienten mit CO über das lebenslange Risiko für die Entwicklung einer sekundären MNV ist daher essenziell, um im Einzelfall frühzeitig zu behandeln. Da derzeit kein festes Therapieschema für intravitreale VEGF-Antikörpern bei CO-assoziierter MNV besteht, erfolgt die Behandlung individuell.
Geriatrie und geriatrische Aspekte im Koalitionsvertrag 2021
Authors: Nohl-Deryk Pascal , Grund Stefan 
Published: September 2023

Zusammenfassung
Hintergrund
Der Anteil älterer Menschen in Deutschland wächst stark. Bis zur Bundestagswahl 2025 geht das Statistische Bundesamt davon aus, dass ein Drittel der Bevölkerung das Rentenalter erreicht haben wird. Ältere Menschen sind damit eine der größten Wählergruppen und politisch besonders relevant.

Fragestellung
Wie fördert die Bundesregierung die Lebensbedingungen dieser Wählergruppe? Was plant sie hinsichtlich der medizinischen Versorgung älterer Menschen?

Methoden
Es erfolgte eine Inhaltsanalyse des Koalitionsvertrages nach Aspekten demografischer Entwicklung, geriatrischer Versorgung und Lebensbedingungen älterer Menschen. Die kodierten Textstellen wurden gemischt induktiv-deduktiv kategorisiert. Schließlich wurde der Umsetzungsfortschritt konkreter Vorhaben nach eineinhalb Jahren Amtszeit beurteilt.

Ergebnisse
Im Text des Koalitionsvertrages wurden 23 Textstellen mit knapp 620 Wörtern (gut 1 % des Textes) identifiziert und kategorisiert. Neun Textstellen ließen sich dem Themenbereich „ältere Bevölkerung“, 6 Textstellen der „medizinischen Versorgung“ und 8 der „pflegerischen Versorgung“ zuordnen. 14 von 23 Textstellen enthielten konkrete Handlungsvorhaben oder Zieldaten. In den ersten eineinhalb Jahren der Bundesregierung konnte bei 4 davon ein teilweiser Fortschritt identifiziert werden, eine Umsetzung erfolgte bei keinem Vorhaben.

Diskussion
Der Koalitionsvertrag lässt insgesamt ein Bewusstsein für eine älter werdende Bevölkerung erkennen. In Anbetracht der demografischen Entwicklung werden allerdings wenige Lösungsvorschläge für genuin geriatrische Aspekte gemacht. Das erste Amtsjahr war stark durch andere Themen geprägt, woraus sich ungeplante Gesetze und Verordnungen ergaben und Vorhaben aus dem Koalitionsvertrag in den Hintergrund rückten.
Alkaline magmas in shallow arc plutonic roots: a field and experimental investigation of hydrous cumulate melting in the southern Adamello batholith

Published: September 2023

AbstractDespite the first-order importance of crystallisation–differentiation for arc magma evolution, several other processes contribute to their compositional diversity. Among them is the remelting of partly crystallised magmas, also known as cumulate melting or ‘petrological cannibalism’. The impact of this process on the plutonic record is poorly constrained. We investigate a nepheline-normative dyke suite close to the Blumone gabbros, a large amphibole-gabbro unit of the Tertiary Southern Alpine Adamello igneous complex. The compositions of the studied dykes are characterised by low SiO2 (43–46 wt. %), MgO (5.0–7.2 wt. %), Ni (18–40 μg/g), and high Al2O3 (20.2–22.0 wt. %) contents. Phenocrystic plagioclase in these dykes exhibits major, trace, and Sr isotope compositions similar to Blumone cumulate plagioclase, suggesting a genetic link between the nepheline-normative dykes and the amphibole-gabbro cumulates. We tested this hypothesis by performing saturation experiments on a nepheline-normative dyke composition in an externally heated pressure vessel at 200 MPa between 975 and 1100 °C at fO2 conditions close to the Ni–NiO buffer. Plagioclase and spinel are near-liquidus phases at and above 1050 °C, contrasting with the typical near-liquidus olivine ± spinel assemblage in hydrous calc-alkaline basalts. The alkaline nature of the dykes results from the abundance of amphibole in the protolith, consistent with melting of amphibole-gabbro cumulates. We modelled the heat budget from the repeated injection of basaltic andesite into a partly crystallised amphibole-gabbro cumulate. The results of this model show that no more than 7% of the cumulate pile reaches temperatures high enough to produce nepheline-normative melts. We propose that such nepheline-normative dykes are a hallmark of hydrous cumulate melting in subvolcanic plumbing systems. Therefore, ne-normative dykes in arc batholiths may indicate periods with high magma fluxes.

AbstractCetaceans are well known for their remarkable cognitive abilities including self-recognition, sound imitation and decision making. In other mammals, the prefrontal cortex (PFC) takes a key role in such cognitive feats. In cetaceans, however, a PFC could up to now not be discerned based on its usual topography. Classical in vivo methods like tract tracing are legally not possible to perform in Cetacea, leaving diffusion-weighted imaging (DWI) as the most viable alternative. This is the first investigation focussed on the identification of the cetacean PFC homologue. In our study, we applied the constrained spherical deconvolution (CSD) algorithm on 3 T DWI scans of three formalin-fixed brains of bottlenose dolphins (Tursiops truncatus) and compared the obtained results to human brains, using the same methodology. We first identified fibres related to the medio-dorsal thalamic nuclei (MD) and then seeded the obtained putative PFC in the dolphin as well as the known PFC in humans. Our results outlined the dolphin PFC in areas not previously studied, in the cranio-lateral, ectolateral and opercular gyri, and furthermore demonstrated a similar connectivity pattern between the human and dolphin PFC. The antero-lateral rotation of the PFC, like in other areas, might be the result of the telescoping process which occurred in these animals during evolution.
Inapproximability of Positive Semidefinite Permanents and Quantum State Tomography
Authors: Meiburg Alexander 
Published: September 2023

AbstractMatrix permanents are hard to compute or even estimate in general. It had been previously suggested that the permanents of Positive Semidefinite (PSD) matrices may have efficient approximations. By relating PSD permanents to a task in quantum state tomography, we show that PSD permanents are NP-hard to approximate within a constant factor, and so admit no polynomial-time approximation scheme (unless P = NP). We also establish that several natural tasks in quantum state tomography, even approximately, are NP-hard in the dimension of the Hilbert space. These state tomography tasks therefore remain hard even with only logarithmically few qubits.
Maternal atopic conditions and autism spectrum disorder: a systematic review

Published: September 2023

AbstractAutism spectrum disorder (ASD) is a disabling neurodevelopmental condition with complex etiology. Emerging evidence has pointed to maternal atopy as a possible risk factor. It is hypothesized that maternal atopic disease during pregnancy can lead to increased levels of inflammatory cytokines in fetal circulation via placental transfer or increased production. These cytokines can then pass through the immature blood–brain barrier, causing aberrant neurodevelopment via mechanisms including premature microglial activation. The objective of this study is to systematically review observational studies that investigate whether a maternal history of atopic disease (asthma, allergy, or eczema/atopic dermatitis) is associated with a diagnosis of ASD in offspring. A search was conducted in Ovid MEDLINE, PsycINFO, and Embase databases for relevant articles up to November 2021; this was later updated in January 2022. Observational studies published in peer-reviewed journals were included. Data were synthesized and qualitatively analyzed according to the specific atopic condition. Quality assessment was done using the Newcastle–Ottawa Scale. Nine articles were identified, with all including asthma as an exposure, alongside four each for allergy and eczema. Findings were inconsistent regarding the association between a maternal diagnosis of either asthma, allergy, or eczema, and ASD in offspring, with variations in methodology contributing to the inconclusiveness. More consistent associations were demonstrated regarding maternal asthma that was treated or diagnosed during pregnancy. Evidence suggests that symptomatic maternal asthma during pregnancy could be associated with ASD in offspring, underscoring the importance of effective management of atopic conditions during pregnancy. Further research is needed, particularly longitudinal studies that use gold-standard assessment tools and correlate clinical outcomes with laboratory and treatment data.PROSPERO Registration Number and Date: CRD42018116656, 26.11.2018.
