Abstract
Background

Ventricular tachycardia (VT) is caused by the presence of a slow conduction channel (CC) of border zone (BZ) tissue inside the scar-core tissue. Electroanatomic mapping can depict this tissue by voltage mapping. Areas of slow conduction can be detected as late potentials (LPs) and their abolition is the most accepted ablation endpoint. In the current guidelines, bipolar voltage thresholds for BZ and core scar are 1.5 and 0.5 mV respectively. The performance of these values is controversial. The aim of the study is to analyze the diagnostic yield of current amplitude thresholds in voltage map to define VT substrate in terms of CCs of LPs. Predictors of usefulness of current thresholds will be analyzed.

Methods
All patients with structural heart disease who underwent VT ablation in Hospital Clinic in 2016–2017 were included. Maps with delineation of CCs based on LPs were created with contact force sensor catheter. Thresholds were adjusted for every patient based on CCs. Diagnostic yield and predictors of performance of conventional thresholds were analyzed.

Results
During study period, 57 consecutive patients were included (age: 60.4 ± 8.5; 50.2% ischemic cardiomyopathy, LVEF 39.8 ± 13.5%). Cutoff voltages that better identified the scar and BZ according to the LP channels were 0.32 (0.02–2 mV) and 1.84 (0.3–6 mV) respectively. Current voltage thresholds identified correctly core and BZ in 87.7% and 42.1% of the patients respectively. Accuracy was worse in non-ischemic cardiomyopathy (NICM) especially for BZ (28.6% vs 55.2%, p = 0.042).

Conclusions
Accuracy of standard voltage thresholds for scar and BZ is poor in terms of LPs detection. Diagnostic yield is worse in NICM patients specially for border zone.
Traveling Fronts in a Reaction–Diffusion Equation with a Memory Term
Authors: Mielke Alexander , Reichelt Sina 
Published: February 2022

AbstractBased on a recent work on traveling waves in spatially nonlocal reaction–diffusion equations, we investigate the existence of traveling fronts in reaction–diffusion equations with a memory term. We will explain how such memory terms can arise from reduction of reaction–diffusion systems if the diffusion constants of the other species can be neglected. In particular, we show that two-scale homogenization of spatially periodic systems can induce spatially homogeneous systems with temporal memory. The existence of fronts is proved using comparison principles as well as a reformulation trick involving an auxiliary speed that allows us to transform memory terms into spatially nonlocal terms. Deriving explicit bounds and monotonicity properties of the wave speed of the arising traveling front, we are able to establish the existence of true traveling fronts for the original problem with memory. Our results are supplemented by numerical simulations.
Law and Geology for the Anthropocene: Toward an Ethics of Encounter
Authors: Damianos Alexander 
Published: February 2022

AbstractThe Anthropocene has been observed as an opportunity to generate new legal imaginaries capable of revising incumbent assumptions of legal and political thought. What opportunities do such ambitions afford for communication between geological and legal thought? Responding to Birrell & Matthews attempt to ‘re-story a lawfor, rather thanof, the Anthropocene,’ I wish to describe some ways in which the Anthropocene Working Group, who are pursuing formalisation of the Anthropocene as an official geological unit, are involved in a similar exercise of re-storying geology. The Anthropocene theme is brought to bear as a geological reality through material practices of measurement and correlation, as well as through the invocation of previous judgements of the evaluative committees associated with the formalisation of new geological unit. This effort amounts to a redefinition of the practices of geological observation, i.e. what counts as geologically relevant and why. In keeping with the theme of an ‘ethics of encounter’, as encouraged by Birrell and Matthews, this article suggests that the AWG’s effort provides a model with which the elaboration of ‘laws for the Anthropocene’ might correspond.
Quasi-likelihood analysis and its applications
Authors: Yoshida Nakahiro 
Published: February 2022

AbstractThe Ibragimov–Khasminskii theory established a scheme that gives asymptotic properties of the likelihood estimators through the convergence of the likelihood ratio random field. This scheme is extending to various nonlinear stochastic processes, combined with a polynomial type large deviation inequality proved for a general locally asymptotically quadratic quasi-likelihood random field. We give an overview of the quasi-likelihood analysis and its applications to ergodic/non-ergodic statistics for stochastic processes.
Philosophers’ linguistic expertise: a psycholinguistic approach to the expertise objection against experimental philosophy
Authors: Fischer Eugen , Engelhardt Paul E. , Herbelot Aurélie 
Published: February 2022

AbstractPhilosophers are often credited with particularly well-developed conceptual skills. The ‘expertise objection’ to experimental philosophy builds on this assumption to challenge inferences from findings about laypeople to conclusions about philosophers. We draw on psycholinguistics to develop and assess this objection. We examine whether philosophers are less or differently susceptible than laypersons to cognitive biases that affect how people understand verbal case descriptions and judge the cases described. We examine two possible sources of difference: Philosophers could be better at deploying concepts, and this could make them less susceptible to comprehension biases (‘linguistic expertise objection’). Alternatively, exposure to different patterns of linguistic usage could render philosophers vulnerable to a fundamental comprehension bias, the linguistic salience bias, at different points (‘linguistic usage objection’). Together, these objections mount a novel ‘master argument’ against experimental philosophy. To develop and empirically assess this argument, we employ corpus analysis and distributional semantic analysis and elicit plausibility ratings from academic philosophers and psychology undergraduates. Our findings suggest philosophers are better at deploying concepts than laypeople but are susceptible to the linguistic salience bias to a similar extent and at similar points. We identify methodological consequences for experimental philosophy and for philosophical thought experiments.
Constructing large peak-pit Condorcet domains

AbstractWe present a new method of constructing Condorcet domains from pairs of Condorcet domains of smaller sizes (concatenation + shuffle scheme). The concatenation + shuffle scheme provides maximal, connected, copious, peak-pit domains whenever the original domains have these properties. It allows to construct maximal peak-pit Condorcet domains that are larger than those obtained by the Fishburn’s alternating scheme for all $$n\ge 13$$

On the Stability of Spinning Asteroids
Authors: Persson B. N. J. , Biele J. 
Published: February 2022

AbstractMost asteroids with a diameter larger than$$\sim 300 \ {\mathrm{m}}$$∼300mare rubble piles, i.e., consisting of more than one solid object. All asteroids are rotating but almost all asteroids larger than$$\sim 300 \ \mathrm{m}$$∼300mrotate with a period longer than$$2.3 \ {\text{hours}}$$2.3hours, which is the critical period where the centrifugal force equals the gravitational force. This indicates that there are nearly no adhesive interaction forces between the asteroid fragments. We show that this is due to the surface roughness of the asteroid particles which reduces the van der Waals interaction between the particles by a factor of 100 for micrometer sized particles and even more for larger particles. We show that surface roughness results in an interaction force which is independent of the size of the particles, in contrast to the linear size dependency expected for particles with smooth surfaces. Thus, two stone fragments of size$$100 \ {\mathrm{nm}}$$100nmattract each other with the same non-gravitational force as two fragments of size$$10 \ {\mathrm{m}}$$10m.

Abstract
Background
Tubal ligation remains common in the USA, especially among low-income patients.

Objective
To compare the effectiveness and safety of intrauterine contraceptives (IUC) to laparoscopic tubal ligation for Medicaid clients.

Design
We partnered with patient and clinician stakeholders to conduct a retrospective cohort study using California Medicaid claims for patients who had an IUC placed or laparoscopic tubal ligation performed in 2008–2014, excluding procedures performed within 42 days of a birth. We applied log-linear (Poisson) event-history regression models for clustered person-period data to adjust for sociodemographic variables and pre-procedure health status when examining associations between these contraceptive procedures and claims related to contraceptive failure, complications, and pain in the first year post-procedure.

Key Results
We identified 35,705 patients who had a levonorgestrel IUC placed, 23,628 patients who had a copper IUC placed, and 23,965 patients who underwent laparoscopic tubal ligation. In unadjusted analyses, rates of pregnancy within 1 year were similar following levonorgestrel IUC (2.40%) or copper IUC placement (2.99%) or tubal ligation (2.64%). In adjusted analyses, compared to tubal ligation, pregnancy was less common following placement of a levonorgestrel IUC (adj IRR 0.72, 95% CI 0.64–0.82) and similar with placement of a copper IUC (adj IRR 0.92, 95% CI 0.82–1.05). Procedural complications such as infection (0.35% vs. 2.91%) were significantly less common with IUC placement than tubal ligation. Claims for pelvic and abdominal pain decreased in frequency with time since all procedures; 6 to 12 months post-procedure, pelvic pain claims were less common after levonorgestrel IUC (adj IRR 0.69, 95% CI 0.65–0.73) or copper IUC placement (adj IRR 0.70, 95% CI 0.66–0.75) than tubal ligation.

Conclusions
IUC appears at least as effective as laparoscopic tubal ligation at 1-year post-procedure with lower rates of infection and pelvic pain 6 to 12 months post-procedure.

Die unbekannte Geburt – Deutungsprozesse gebärender Frauen
Authors: Eckardt Sarah 
Published: February 2022

ZusammenfassungEine Geburt als ein individuelles Projekt zu begreifen, ist eine zentrale These in der soziologischen Natalitätsforschung. Um eine gute Geburt für Mutter, Kind und Partner*in gemäß dem medizinischen Selbstbestimmungsparadigma aktiv positiv gestalten zu können, scheinen umfangreiche Vorbereitungen und Entscheidungen notwendig zu sein. Die Geburt, so die These, würde nahezu wie ein Event individuell inszeniert. Gleichzeitig ist es von Bedeutung, Geburt als sozial geprägtes Ereignis zu verstehen, das durch divergierende Dispositive auf spezifische Art und Weise hervorgebracht wird. Dabei ist das biomedizinische Risikodispositiv als hegemonial anzusehen, hinzukommen spezifische gesellschaftliche Entwicklungen wie die Ökonomisierung des Gesundheitssystems oder die Zentralisierungen der Geburtskliniken. Folglich sind die Möglichkeitsräume zur aktiven Gestaltung der Geburt strukturell begrenzt. Das medizinische Geburtshilfesystem ist in seinen Praktiken und Deutungen der Geburt repressiv und machtvoll. Wie sich Frauen in dem spannungsreichen dispositiven Feld der Geburt bewegen und positionieren, Diskurse weiterschreiben und verändern, war die Fragestellung des vorliegenden Projekts. Im Zentrum standen die Subjektivierungsweisen gebärender Frauen. Dazu führte ich Interviews mit neun Frauen kurz vor und kurz nach der Geburt. In einer Verschränkung von Dispositivanalyse und Grounded Theory wertete ich das Material aus. Der Beitrag fordert dazu auf, Geburt als ein grundlegend unbekanntes Phänomen zu begreifen, dem sich Frauen durch verschiedene Praktiken annähern. Deutlich wird in der Analyse, dass die Deutung der Geburt diskursiv als ein unbekanntes Phänomen konstruiert ist. Mein Beitrag diskutiert die Auswirkung dieser Deutung und deren Verstrickung mit Bio-Macht und Weiblichkeit.
Diagnostic Approach to Incidentally Detected Pancreatic Cystic Lesions

Published: February 2022

Abstract
Purpose of review
The objective of this study is to answer few key questions in order to establish the best possible available diagnostic strategy for incidentally discovered pancreatic cystic lesions (PCLs).

Recent findings
Advances in EUS-guided sampling techniques, cross-sectional and intracystic confocal imaging, molecular biomarkers analysis, determination of cyst fluid glucose, and artificial intelligence, appear to be associated with an improved diagnostic accuracy in distinguishing mucinous from non-mucinous PCLs.

Summary
The diagnostic process has the aim of recognizing cysts with malignant potential and identifying those with high-risk stigmata and/or worrisome features. Clinicians should avoid performance of unnecessary tests from one side and misdiagnosis from the other, which can easily result in inadvertent surgery of an otherwise benign lesion or malignant progression of a precancerous cyst. Clinical studies to validate recent reported results utilizing novel diagnostic tests are needed, in order to gradually incorporate and combine them into updated guidelines.
Who will I be when I retire? The role of organizational commitment, group memberships and retirement transition framing on older worker’s anticipated identity change in retirement
Authors: Jolles Daniel , Lamarche Veronica M. , Rolison Jonathan J. , Juanchich Marie 
Published: February 2022

AbstractRetirement is an eagerly awaited life transition for many older workers, but some may anticipate their exit from the workforce will result in loss of meaningful work-based activities and social interactions. For older workers more committed to their organization, retirement might represent a threat to maintaining a consistent, positive identity. Across three pre-registered studies of US adults aged 49 to 75, we investigated the relationship between organizational commitment and anticipated identity changes in retirement. Studies 1 and 2 (N = 1059) found that older workers largely anticipated positive changes to their identity in retirement. In Study 2, we divided older workers into two conditions and used a framing manipulation to present retirement as either a ‘role exit’ or a ‘role entry’. In the ‘role exit’ condition, older workers less committed to their organization anticipated more positive changes when they held more group memberships compared to those with fewer group memberships. Those in the ‘role entry’ condition anticipated significantly more positive changes to their identity in retirement than those in the ‘role exit’ condition, but did not anticipate more positive changes based on organizational commitment or group memberships. More group memberships, but not lower organizational commitment, was associated with more positive anticipation of identity changes in retirement. Study 3 (N = 215) surveyed older adults after they had retired, finding that identity changes experienced post-retirement were less positive than those anticipated by older workers. We discuss the theoretical and applied implications of these findings for older workers’ retirement decisions and wellbeing.

AbstractIn this study, we interpret codependency as a dysfunctional pattern of relating to others, and based on this approach, we hypothesized an association with negative forms of dyadic coping, relationship problems and life satisfaction. A total of 246 Hungarian participants (167 females, 79 males), aged 18–72 years (M = 35.3, SD = 11.6) completed our online survey including measures of codependency, dyadic coping, perceptions of relationship, and life satisfaction. In our cross-sectional research, the Spann-Fischer Codependency Scale (SF-CDS), the Dyadic Coping Inventory (DCI), the Shortened Marital Stress Scale (MSS-R), and the Satisfaction With Life Scale (SWLS) were used. Correlational and pathway analyzes were applied to confirm our hypotheses. Codependency was associated with negative dyadic coping, while we found no measurable influence on positive dyadic coping. Individuals with higher codependency rated both their own and their partner’s negative dyadic coping more pronounced, while at the same time they characterized their relationships as more problematic. Structural Equation Modelling proved that codependent attitudes, along with the emergence of negative dyadic coping forms and perception of relationship problems, reduce a person’s life satisfaction. Overall, it can be stated that the more codependent the participants were, the more negative their own and partner’s behaviour was perceived in stressful situations and the more problematic their intimate relationship was found to be. Our results support the idea that codependency is a specific, largely stable attitude that determines a person’s perception and behaviour relating to others.
Deep-Space Optical Navigation Exploiting Multiple Beacons
Authors: Franzese V. , Topputo F. 
Published: February 2022

AbstractGround facilities relying on traditional radiometric tracking are reaching saturation due to the growth of satellites launched into space. As such, autonomous navigation is one of the main enabling technologies for sustainable deep-space missions. This paper tackles the deep-space optical navigation problem exploiting multiple beacons to estimate the observer position independently from ground. The paper derives the least-squares solution and the analytical covariance to the deep-space navigation problem exploiting multiple beacons. The perturbations in the line-of-sight directions as well as in the objects ephemeris are incorporated into the covariance formulation. Then, the geometrical interpretation of the perturbations models, the navigation solution, and the navigation covariance are elaborated. The sensitivity of the navigation accuracy to the number of beacons is assessed by virtue of a test case, showing the correspondence between the numerical and the analytical solutions. Eventually, the paper shows the comparison of the navigation accuracy exploiting multiple beacons against two optimal beacons.
Is paying bribes worthwhile? Corruption and innovation in middle-income countries
Authors: Iorio Roberto , Segnana Maria Luigia 
Published: February 2022

AbstractCorruption research in economics has a long history. Seminal early articles, and older findings contrast with newer developments which have as yet not been measured empirically; in particular the link between corruption and innovating activities suffers from multiple results, on both a national country and company or firm level. This paper examines the corruption-innovation link in transition and emerging countries as the decision to corrupt, and the ability to innovate may not be independent. An endogenous switching regression model is advocated as a suitably methodological way of modeling the joint determination of a firm’s innovation and possible bribes as it implies not only a selection between corrupted and non-corrupted firms, but also heterogeneous effects on innovative activities. The paper shows that, when the selection effect is adequately considered, different firms’ strategies arise. In particular, the treatment effect of corruption on innovation is positive for corrupting firms and negative for non-corrupting firms. Corrupting firms appear rational because paying bribes increases their innovative activities. However, non-corrupting firms also appear rational because in the presence of bribes, their innovating activities would be fewer. Thus, when the selection effect is adequately considered, the effects of so-called “greasing-and-sanding-the-wheels” can co-exist. Finally, the role of competition is also considered. Building on these results, future research can move forward to re-examine economic outcomes such as the productivity or the economic impact of corruption, in the presence (or absence) of selection processes.
A cross-cultural exploration of compassion, and facilitators and inhibitors of compassion in UK and Sri Lankan people

Published: February 2022

AbstractBackgroundPractising compassion has shown to increase well-being and reduce distress in people across cultures. However, very little research has explored cultural differences in different facets of compassion with a dearth of research evident especially in the Asian context. Several inhibitors and facilitators of compassion have been identified although the nuances of cultural differences of these remain unexploited. This study aimed to discover cross-cultural similarities and differences of the levels of compassion, facilitators and inhibitors of compassion between Sri Lankan and UK people.MethodsA cross-sectional, questionnaire-based quantitative research was conducted among 149 Sri Lankan and 300 UK participants. Individual predictors (such as fears of compassion, self-reassurance, external shame, social safeness and pleasure, depression and anxiety) were also explored in relation to compassion, compassion to others, and compassion from others in each group.ResultsThe results indicated that Sri Lankan participants were more self-reassured and self-compassionate and self-identifying as a Buddhist predicted higher self-compassion, when compared to UK participants. However, Sri Lankan participants reported higher levels of external shame and fear of compassion not just towards themselves, but also towards and from others, indicating difficulty in engaging compassionately with others. In contrast, UK participants reported higher social safeness, indicating that they were more likely to feel safe and soothed by the society than the Sri Lankan participants.ConclusionsSociety plays a pivotal role in shaping one's experiences of compassion. This study suggests that specific cultural and social factors should be considered when implementing Western compassionate approaches to non-Western settings.
