#### Dispersion relations for $\eta '\rightarrow \eta \pi \pi$

We present a dispersive analysis of the decay amplitude for $\eta '\rightarrow \eta \pi \pi$ that is based on the fundamental principles of analyticity and unitarity. In this framework, final-state interactions are fully taken into account. Our dispersive representation relies only on input for the ${\pi \pi }$ and ${\pi }\eta$ scattering phase shifts. Isospin symmetry ...

#### Remarks on Farah’s Theorems

The aim of this paper is to prove two Farah’s Theorems concerning approximate group homomorphisms, without some assumptions present in Farah’s Theorems. Farah’s approach to the Ulam’s type stability of homomorphisms between finite groups seems appropriate and interesting.

#### DNA methylation in ELOVL2 and C1orf132 correctly predicted chronological age of individuals from three disease groups

Improving accuracy of the available predictive DNA methods is important for their wider use in routine forensic work. Information on age in the process of identification of an unknown individual may provide important hints that can speed up the process of investigation. DNA methylation markers have been demonstrated to provide accurate age estimation in forensics, but there is ...

#### Individual and environmental correlates of objectively measured physical activity and sedentary time in adults from Curitiba, Brazil

Objectives This study assessed the association of individual and neighborhood environment characteristics and objectively measured physical activity (PA) and sedentary time (ST) in adults from Curitiba, Brazil. Methods A population-based cross-sectional study was conducted through face-to-face household interviews in 2010. The analytic sample included 305 adults aged 20–65 years ...

#### Crowd logistics: an opportunity for more sustainable urban freight transport?

Purpose Passenger car occupancy has been falling for years. Partly empty vehicles on our road networks decrease passenger transport sustainability but also contain an opportunity for freight transport. Within Crowd logistics (CL), delivery operations are carried out by using passengers’ excess capacity on journeys that are already taking place, resulting in economic, social and ...

#### Treatment of Bisphenol A-Containing Effluents from Aerobic Granular Sludge Reactors with the Use of Microfiltration and Ultrafiltration Ceramic Membranes

This study investigated the use of ceramic membranes to remove total suspended solids (TSS), organics (expressed by chemical oxygen demand, COD), and bisphenol A (BPA) via microfiltration (MF, pore size 0.45 μm) and ultrafiltration (UF, cutoff 150 kDa) in post-treatment of effluents from aerobic granular sludge reactors (GSBRs). The efficiency of removal of COD, BPA, and TSS in MF ...

#### Policy entrepreneurs in international river basins—getting climate adaptation on the cross-border water policy agenda

In this study, we look at the role which water policy entrepreneurs play in promoting and stimulating climate adaptation measures in international river basins. In a Dutch-German case study in the Rhine delta, we explore the range of strategies that policy entrepreneurs employ in cross-border water management to effectively anchor and embed climate adaptation in the water policy ...

#### Iterated local search for workforce scheduling and routing problems

The integration of scheduling workers to perform tasks with the traditional vehicle routing problem gives rise to the workforce scheduling and routing problems (WSRP). In the WSRP, a number of service technicians with different skills, and tasks at different locations with pre-defined time windows and skill requirements are given. It is required to find an assignment and ordering ...

#### Huisarts besteedt meer tijd aan oudere patiënt

Tussen 2013 en 2016 nam de ervaren werklast en de duur van de contacten met oudere patiënten in de huisartsenpraktijk toe. Daarnaast werken huisartsen, mede door veranderingen in de wetgeving in 2015, samen met meerdere partijen in de zorg. Een hogere werkdruk in de huisartsenpraktijk dus, waarvan het de vraag is of die houdbaar is voor de toekomst.

#### Diet uniformity at an early farming community in northwest Anatolia (Turkey): carbon and nitrogen isotope studies of bone collagen at Aktopraklık

Aktopraklık is a settlement site composed of three areas (A–C) in the Marmara region of northwest Anatolia, with phases of occupation that date to the Late Neolithic and Early Chalcolithic periods, mid-seventh to mid-sixth millennium bc (ca. 6400–5600 cal. bc). Here, we present 54 human and fauna bone collagen stable isotope results from the site, alongside five modern fish bone ...

#### Feasibility of a self-help web-based intervention targeting young cancer patients with sexual problems and fertility distress

Purpose The purpose of the study is to evaluate the feasibility of a self-help web-based intervention to alleviate sexual problems and fertility distress in adolescents and young adults with cancer. Methods Twenty-three persons with cancer (19 women and 4 men, age 18–43, 1–5 years post-diagnosis of lymphoma, breast, gynecologic, central nervous system, or testicular cancer) were ...

#### Don’t let it distract you: how information about the availability of reward affects attentional selection

Previous research has shown that attentional selection is affected by reward contingencies: previously selected and rewarded stimuli continue to capture attention even if the reward contingencies are no longer in place. In the current study, we investigated whether attentional selection also is affected by stimuli that merely signal the magnitude of reward available on a given ...

#### Routine follow-up radiographs for distal radius fractures are seldom clinically substantiated

Introduction The value of routine radiographs during follow-up after distal radius fractures is unclear. The aim of this study was to evaluate whether routine radiographs performed during the follow-up period in patients with a distal radius fracture influenced clinical decision making. Methods This retrospective cohort study included patients aged ≥18 years who were treated for a ...

#### Sequent Systems for Negative Modalities

Non-classical negations may fail to be contradictory-forming operators in more than one way, and they often fail also to respect fundamental meta-logical properties such as the replacement property. Such drawbacks are witnessed by intricate semantics and proof systems, whose philosophical interpretations and computational properties are found wanting. In this paper we investigate ...

#### Trivial Languages

I here present and defend what I call the Triviality Theory of Truth (TT), to be understood in analogy with Matti Eklund’s Inconsistency Theory of Truth (IT). A specific formulation of (TT) is defended and compared with alternatives found in the literature. A number of objections against the proposed notion of meaning-constitutivity are discussed and held inconclusive. The main ...

#### Promoting Pluralism in Counselling: an Untapped Source of Relational Mapping as Therapeutic Process

This paper discusses the merits of pluralism in practice. It argues for a wider recognition of creative and integrative approaches, such as those used in the field of children’s geographies (involving places and spaces), as a way of unlocking practitioner potential and innovation. By re-thinking child and human development, viewing it as socially, culturally and philosophically ...

#### Cross-border agglomeration benefits

Spatial correlations exist for many economic phenomena. We also know such interactions are typically weaker across country borders than within countries, due to institutional, infrastructural or cultural factors. However, in spatial econometric analyses, the effect of borders is rarely taken into account, and all borders between regions are treated as equal. We distinguish between ...

#### Melasma: an Up-to-Date Comprehensive Review

Melasma is a common acquired condition of symmetric hyperpigmentation, typically occurring on the face, with higher prevalence in females and darker skin types. Multiple etiologies, including light exposure, hormonal influences, and family history, have been implicated in the pathogenesis of this disorder. Overall prevalence ranges widely at 1–50%, since values are typically ...

#### On functional representations of the conformal algebra

Starting with conformally covariant correlation functions, a sequence of functional representations of the conformal algebra is constructed. A key step is the introduction of representations which involve an auxiliary functional. It is observed that these functionals are not arbitrary but rather must satisfy a pair of consistency equations corresponding to dilatation and special ...

#### High waves in Draupner seas—Part 2: Observation and prediction from synthetic radar images

In Part 1, Van Groesen et al. (J Ocean Eng Mar Energy, 2017), a numerical study of extreme waves in so-called Draupner seas showed that extreme crest heights of 18 m, one-and-a-half times the significant wave height, occur in a time span of 20 min on average in every area less than 1 km$^2$. Such extreme, steep waves are dangerous for ships and offshore structures. In this Part ...

#### Compassion for Others and Self-Compassion: Levels, Correlates, and Relationship with Psychological Well-being

Compassion for others and self-compassion are assumed to be closely related concepts. Yet, as they have been mostly studied separately, little is known about their relationship and to what extent they differ or resemble each other with respect to their correlates. This cross-sectional study aimed to gain knowledge on their mean levels, interrelationship, and relationships to ...
