L

-Liouville property in terms of the Green function of the graph and use it to prove its equivalence with stochastic completeness on model graphs. Moreover, we show that there exist stochastically incomplete graphs which satisfy the $$ L^1 $$

Molecular dissection of heterosis in cereal roots and their rhizosphere
Authors: Baldauf Jutta A. , Hochholdinger Frank 
Published: July 2023

Abstract
Key message
Heterosis is already manifested early in root development. Consistent with the dominance model of heterosis, gene expression complementation is a general mechanism that contributes to phenotypic heterosis in maize hybrids.

Abstract
Highly heterozygous F1-hybrids outperform their parental inbred lines, a phenomenon known as heterosis. Utilization of heterosis is of paramount agricultural importance and has been widely applied to increase yield in many crop cultivars. Plant roots display heterosis for many traits and are an important target for further crop improvement. To explain the molecular basis of heterosis, several genetic hypotheses have been proposed. In recent years, high-throughput gene expression profiling techniques have been applied to investigate hybrid vigor. Consistent with the classical genetic dominance model, gene expression complementation has been demonstrated to be a general mechanism to contribute to phenotypic heterosis in diverse maize hybrids. Functional classification of these genes supported the notion that gene expression complementation can dynamically promote hybrid vigor under fluctuating environmental conditions. Hybrids tend to respond differently to available nutrients in the soil. It was hypothesized that hybrid vigor is promoted through a higher nutrient use efficiency which is linked to an improved root system performance of hybrids in comparison to their inbred parents. Recently, the interaction between soil microbes and their plant host was added as further dimension to disentangle heterosis in the belowground part of plants. Soil microbes influenced the performance of maize hybrids as illustrated in comparisons of sterile soil and soil inhabited by beneficial microorganisms.
Resistance spot welding of dissimilar material joints with a cold-gas-sprayed inlayer

Published: July 2023

AbstractIn this publication, cold gas spraying (CGS) is investigated as an enabler for aluminum-steel joints. Using a powder-based coating process to adhere a steel layer to an aluminum substrate allows a steel component to be welded to the deposited layer by resistance spot welding. This method permits the metallurgical connection between similar materials to be separated, while mechanical bonding ensures the connection at the dissimilar aluminum-to-inlayer interface. A modification of the porous CGS layer, as well as the creation of the remelted zone in the aluminum, can be observed during the resistance spot welding process. Electron backscatter diffraction (EBSD) analyses show that the severely prestressed particles in the CGS coating recrystallize, which coincides with a decrease in defect density and hardness in the heat-affected zone. Microscopy of the aluminum substrate shows the creation of metallurgical pores as well as the expansion of pores attributed to the casting process. The rise in remelted aluminum hardness and decrease in the heat-affected zone of the CGS layer indicate the formation of a metallurgical notch.
Nonlinear active control of thermally induced pyro-coupled vibrations in porous-agglomerated CNT core sandwich plate with magneto-piezo-elastic facings

Published: July 2023

AbstractIn this article, the damped nonlinear transient response of a smart sandwich plate (SSP) comprising of agglomerated CNT-reinforced porous nanocomposite core with multifunctional magneto-piezo-elastic (MPE) facesheets, subjected to the thermal environment, is numerically investigated. The synergistic influence of agglomeration, porosity and pyro-coupling on vibration control is studied for the first time under the finite element framework. The attenuation of the vibrations is caused by active constrained layer damping (ACLD) treatment. The kinematics of the plate is based on the layer-wise shear deformation theory and von-Karman’s nonlinearity. The viscoelastic properties of the ACLD patch and CNT agglomeration of the core are mathematically modelled using Golla–Hughes–McTavish and Eshelby–Mori–Tanaka methods, respectively. A comprehensive examination of the inter-related effects of different agglomeration states, porosity distributions and thermal loading profiles has been performed. The new insights on controlling pyro-coupled induced vibrations of smart sandwich plates by supplying control voltage directly to the MPE facesheets without ACLD treatment have been discussed thoroughly. The numerical analysis confirms the significant effects of pyro-coupling associated with active vibration control response of SSP.

Published: July 2023

AbstractMyasthenia gravis (MG) is an autoimmune disease characterized by weakness and rapid fatigue. Diagnostic methods used for myasthenia gravis are not conclusive and satisfactory, therefore it is necessary to develop reliable tools to help diagnose myasthenia gravis as early as possible. The aim of the study was to use HPLC–MS in conjunction with multivariate statistical analyses to investigate changes in the amino acid metabolic profiles between myasthenia gravis patients compared and controls. In addition, the effect of treatment regimens and myasthenia gravis type, on the observed changes in amino acid metabolic profiles were assessed. Serum levels of 29 amino acids were determined in 2 groups of individuals—28 patients with myasthenia gravis and 53 control subjects (CS). The results of our study indicate that serum levels of several amino acids in patients with myasthenia gravis changed significantly compared to the control group. Statistical analysis revealed differences between amino acids concentration in patients with different therapeutic scheme. In conclusion, amino acids may be involved in mechanisms underlying myasthenia gravis pathogenesis as well as may be potential biomarkers in MG patients diagnosis. However, considering the multifactorial, heterogenous and complex nature of this disease, validation on a larger study sample in further research is required before application into diagnostic practice.
Exploring the interplay of stress, recovery, and physical activity among teachers, nursing staff, and ICT workers: a comparative study
Authors: Tuominen Pipsa P. A. 
Published: July 2023

Abstract
Aim
The interaction between stress and recovery in work and leisure time is a complicated combination of occupational demands, personal physical activity (PA), and recovery needs. This study aimed to explore the interaction of stress and recovery with PA and sedentary time among teachers, nursing staff, and information and communication (ICT) workers.

Methods
The study included a diverse sample of participants (n = 211) from the occupational groups who participated in the Sustainable Brain Health project in Finland. Statistical analyses involved Fisher–Freeman–Halton’s exact test, one-way ANOVA, and Spearman’s Rho for analyzing differences between groups and associations between variables.

Results
Results indicated that teachers felt more burdened than nursing staff or ICT workers. Teachers also engaged in more measured moderate to vigorous PA (MVPA), although their highest training effect from a single exercise was lower than among other occupations. Measured sedentary time was highest among ICT workers and lowest among nursing staff, despite the latter reporting more sitting during leisure time. Notably, ICT workers reported the highest levels of sitting during working hours. Furthermore, measured stress and relaxation proportions showed a strong negative association, while self-perceived recovery breaks were negatively associated with self-perceived stress. Finally, self-perceived exercise intensity was linked to self-perceived exercise enough for health, and measured MVPA proportion correlated with the training effect.

Conclusion
The findings highlight the differential experiences and challenges faced by these occupational groups. The results emphasize the importance of considering gender-dominated occupations when designing interventions to address stress and promote PA.

Abstract
Background
The CohRTA multicenter study aims to characterize patients undergoing a first treatment for alcohol use disorder (AUD). The objective is to analyze sex-specific differences in the comorbidity of AUD when starting the first treatment for the disorder.

Methods
A multicenter study was carried out between 2014 and 2021 in 6 public centers in Spain. Sociodemographic characteristics were collected, variables related to alcohol consumption, medical comorbidity according to Cumulative Illness Rating Scale-Substance Abuse (CIRS-SA), antecedent of psychiatric comorbidity, general blood test and screening for drugs in urine. Logistic regression models were used to establish associations.

Results
A total of 896 patients (634 M, 262 W) were included. Median age at admission was 48 years [IQR:41–56 years]. Men reported beginning regular alcohol consumption at an earlier age and drank more alcohol. The most frequent medical comorbidities were hepatic, respiratory, vascular and neurological. The median number of affected systems was three, with no differences between men and women. However, depressive disorder was more frequent in women. In the multivariate analysis, women were up to 4 times more likely to have a major depressive disorder, elevated ESR and elevated total cholesterol than men. Men started alcohol consumption earlier, had a higher body mass index (BMI), a higher probability of using cocaine and a higher frequency of GGT and bilirubin alteration than women.

Conclusion
Differences by sex were found among individuals beginning first treatment for AUD. These differences must be taken into account when designing specific therapeutic strategies for men and women.
Navigating or adding to complexity? Exploring the role of catchment partnerships in collaborative governance

Published: July 2023

AbstractAn enduring challenge for environmental governance is how to coordinate multiple actors to achieve more collaborative and holistic management of complex socio-ecological systems. Catchment partnerships are often thought able to achieve this, so here we ask: do such partnerships actually help navigate complexity, or merely add to it? We answer this question by analysing the experiences of four voluntary UK catchment partnerships. Our data combined a structured desk-based analysis of partnership documents, with semi-structured interviews with partnership coordinators, chairs and partner representatives. These data were analysed using a qualitative thematic approach informed by the literatures on catchment management and collaborative governance of complexity. We found that partnerships both add to and help navigate the complexity of holistic and inclusive environmental management. Maintaining partnerships entails costs for partners, and partnerships connect messily and multitudinously to other initiatives. However, the partnerships were all judged as worthwhile, and made progress towards goals for water quality, biodiversity and river restoration. They were especially valued for envisioning and initiating complex activities such as Natural Flood Management. Communication and networking by partnership coordinators and partners underpinned these achievements. Aspects of pre-existing governance systems both enabled and constrained the partnerships: in particular, statutory agencies responsible for policy delivery were always important partners, and delivering partnership plans often depended on public-sector grants. This draws attention to the pervasive effect of governmentality in collaborative governance. More attention to analysing—and supporting—such partnerships is worthwhile, complemented by reflection on the limits to environmental governance in the face of complexity.

Published: July 2023

AbstractDespite standardized surgical technique and peri-operative care, metabolic outcomes of bariatric surgery are not uniform. Adaptive changes in brain function may play a crucial role in achieving optimal postbariatric weight loss. This review follows the anatomic-physiologic structure of the postbariatric nutrient-gut-brain communication chain through its key stations and provides a concise summary of recent findings in bariatric physiology, with a special focus on the composition of the intestinal milieu, intestinal nutrient sensing, vagal nerve-mediated gastrointestinal satiation signals, circulating hormones and nutrients, as well as descending neural signals from the forebrain. The results of interventional studies using brain or vagal nerve stimulation to induce weight loss are also summarized. Ultimately, suggestions are made for future diagnostic and therapeutic research for the treatment of obesity.

Published: July 2023

Abstract
Introduction
Direct oral anticoagulants (DOACs) are underused in the elderly, regardless the evidence in their favour in this population.

Methods
We prospectively enrolled anticoagulant-naïve patients aged ≥ 75 years who started treatment with DOACs for atrial fibrillation (AF) and stratified them in older adults (aged 75–84 years) and extremely older adults (≥ 85 years). Thrombotic and hemorrhagic events were evaluated for 12 months follow-up.

Results
We enrolled 518 consecutive patients. They were mostly aged 75–84 years (299 patients; 57.7%) vs. ≥ 85 years (219 patients; 42.3%). Extremely older adults showed higher incidence of all the endpoints (systemic cardioembolism [HR 3.25 (95% CI 1.71–6.18)], major bleeding [HR 2.75 (95% CI 1.77–4.27)], and clinically relevant non-major bleeding [HR 2.13 (95% CI 1.17–3.92)]) vs. older adults during the first year after starting anticoagulation. In patients aged ≥ 85 years, no difference in the aforementioned endpoints was found between those receiving on-label vs. off-label DOACs. In the extremely older adults, chronic kidney disease, polypharmacy, use of antipsychotics, and DOAC discontinuation correlated with higher rates of thrombotic events, whereas a history of bleeding, Charlson Index ≥ 6, use of reduced DOAC dose, absence of a caregiver, use of non-steroidal anti-inflammatory drugs (NSAIDs), and HAS-BLED score ≥ 3 were associated with major bleedings.

Conclusions
Naïve patients aged ≥ 85 who started a DOAC for AF are at higher risk of thrombotic and bleeding events compared to those aged 75–84 years in the first year of therapy. History of bleeding, HAS-BLED score ≥ 3 and use of NSAIDs are associated with higher rates of major bleeding.
Non-suicidal self-injury in Portuguese college students: relationship with emotion regulation, resilience and self-compassion
Authors: Gonçalves Sónia , Vieira Ana Isabel , Machado Bárbara Cesar , Bessa Catarina 
Published: July 2023

AbstractNon-Suicidal Self-Injury (NSSI) are behaviors relatively frequent among college students and seem to be associated to difficulties in emotion regulation. Less is known, however, about the relationship of NSSI with protective factors such as resilience and self-compassion. The aims of this study are to compare three groups of Portuguese college students (without NSSI, past NSSI, and current NSSI) regarding difficulties in emotion regulation, resilience, and self-compassion and to evaluate the predictors of NSSI considering demographics and those risk and protective factors. Three hundred and eighty-five college students were evaluated through self-report measures. Ninety participants (23.4%) reported lifetime NSSI. These participants reported higher difficulties in emotion regulation and lower resilience and self-compassion than the group without NSSI. The group with current NSSI presented the lowest levels of resilience and self-compassion. Lifetime NSSI was significantly associated with past suicide attempts. Past psychopathology and lower self-compassion were predictors of NSSI. Interventions for decrease NSSI in college students should promote adaptive emotion regulation strategies, resilience, and self-compassion.
Europe’s Refugee “Crises” and the Biopolitics of Risk
Authors: Corcodel Veronica , Fragkou Dimitra 
Published: July 2023

AbstractThis paper provides an analysis of the legal and policy foundations of the different approaches adopted by the European Union (EU) in relation to the 2015/2016 and 2022 refugee “crises”. Its main objective is to show how a risk-based biopolitical framework can bridge the gap between EU institutional narratives and the critique of Europe’s racialised governance schemes. The two “crises” have been largely shaped by a perceived need to manage risk, yet this has produced very different institutional responses, in ways that concealed their racialised dimension. Analysing how risk has been understood in the two contexts, the paper shows how their legal and policy foundations (re-)produce a racialised differential scheme. Amidst ongoing debates on reforming EU migration and asylum law, the paper also shows how the current proposals further consolidate this scheme.
COVID-19 and the International Politics of Blame: Assessing China's Crisis (Mis)Management Practices
Authors: Loh Dylan M. H. , Loke Beverley 
Published: July 2023

AbstractThe COVID-19 pandemic has exposed a global health and political crisis like no other in recent history. As ground zero of the virus outbreak, significant criticism and blame have been directed at China for covering up the outbreak. Yet a systematic assessment of China's responses to international opprobrium of its pandemic measures has been largely lacking in the literature. Drawing on the concept of “blame” from public administration, this article seeks to fill this gap by investigating China's COVID-19 crisis and blame (mis)management practices. We make two key contributions in this article. First, we highlight how Beijing engaged in the politics of blame and outline three modes (defensive, aggressive and proactive benevolence) of its blame management practices. Second, we suggest that China sought to articulate and refine its identity during the COVID-19 pandemic, providing insights into a China that is increasingly assertive yet vulnerable to reputational damage. We contend that China's efforts to counter international opprobrium and shift strategic narratives speak directly to issues of autocratic legitimation and its conceived “responsible great power” identity, with greater success among domestic rather than global audiences.
Tver’ Karelian as a new dialect
Authors: Koivisto Vesa 
Published: July 2023

AbstractIn the article, the development of the Tver’ Karelian dialect is discussed. This new dialect has emerged from a mix of regional dialects of Karelian immigrants from the seventeenth century onwards. Characteristics of a new dialect in Tver’ Karelian are examined on the basis of demographic data and linguistic descriptions. In addition, the unity and internal variation of Tver’ Karelian as well as its relation to other Karelian dialects are taken into consideration. In regard to this kind of comparative study, the article reveals some significant regional shortcomings in the linguistic research material available. A discrepancy could also be found between the areal distribution of certain linguistic features of Tver’ Karelian and the main region of origin indicated by historical documents.
Repugnance, externalities and subjectivism: a comment on Krawiec
Authors: Daou Marie , Marciano Alain 
Published: July 2023

AbstractIn her ‘Markets, repugnance, and externalities’ (2022), Kimberly Krawiec notes that the so-called corruption theorists fail to provide evidence that the adoption of repugnant behaviours or commodification destroy social values. She adds that, the values repugnant behaviours are supposed to destroy may even be reinforced after a market has been created. The explanation she explores is that the creation of a market never goes without debates that allow the society to ponder the values it stands for. We suggest an alternative view on the lack of evidence Krawiec identifies. Our starting point is Krawiec's interpretation of repugnance in terms of externalities. We claim that an analysis of repugnance based on externalities requires a characterization of what an externality is, which is rarely done. We show that economists use two opposed definitions of externalities, an objective and a subjective one, and then show what it implies for an analysis of repugnance and justify why the corruption thesis is not always verified empirically.
