Multiplication and Composition in Weighted Modulation Spaces
We study the existence of the product of two weighted modulation spaces. For
this purpose we discuss two different strategies. The more simple one allows
transparent proofs in various situations. However, our second method allows a
closer look onto associated norm inequalities under restrictions in the Fourier
image. This will give us the opportunity to treat the boundedness of
composition operators.Comment: 49 page
Being active when living within a large body:experiences during lifestyle intervention
Background: In-depth understanding of the experiences of both well-being and suffering in relation to being severely obese and becoming active through lifestyle intervention is lacking.
Aim: to explore and describe adultsâ existential experiences of being active, when living within a large bodyâbefore and during a lifestyle intervention.
Methods: A longitudinal design of repeated individual interviews with 16 adults with BMI âĽ40, based on hermeneutic phenomenology, existential philosophy and a theory of well-being was performed. The study was approved by the Danish health authorities.
Results: Two dimensions of experiences were found; âLiving within a downward spiralâ and âStriving for enjoyment and settlementâ. The themes describing suffering were: âSense of being thwarted and defeated â and âTackling energy depletion and impact of sense of selfâ. The themes describing well-being were: âHoping for renewal and energised resolutenessâ and âEnduring discomfort and feeling safeâ.
Conclusions: Interacting existential experiences can be facilitators or barriers for physical activity. It seems relevant for health care providers to address the individualâs lifeworld experiences of well-being, lack of well-being and suffering. Well-being as a sense of feeling âat homeâ when physically active may break down an inactivity spiral. Promoting well-being is a legitimate aim of lifestyle intervention.publishedVersionPaid Open Acces
Quasicontinuum -decay of Zr: benchmarking indirect () cross section measurements for the -process
Nuclear level densities (NLDs) and -ray strength functions
(SFs) have been extracted from particle- coincidences of the
Zr()Zr and Zr()Zr
reactions using the Oslo method. The new Zr SF data, combined
with photonuclear cross sections, cover the whole energy range from ~MeV up to the giant dipole resonance at ~MeV. The wide-range SF data display structures at ~MeV, compatible with a superposition of the spin-flip
resonance and a pygmy resonance. Furthermore, the SF shows a
minimum at ~MeV and an increase at lower -ray
energies. The experimentally constrained NLDs and SFs are shown to
reproduce known () and Maxwellian-averaged cross sections for
Zr using the {\sf TALYS} reaction code, thus serving as a benchmark
for this indirect method of estimating () cross sections for Zr
isotopes.Comment: 10 pages and 9 figure
Lectin staining shows no evidence of involvement of glycocalyx/mucous layer carbohydrate structures in development of celiac disease
The presence of unique carbohydrate structures in the glycocalyx/mucous layer of the intestine may be involved in a susceptibility to celiac disease (CD) by serving as attachment sites for bacteria. This host-microbiota interaction may influence the development of CD and possibly other diseases with autoimmune components. We examined duodenal biopsies from a total of 30 children, of which 10 had both celiac disease (CD) and type 1 diabetes (T1D); 10 had CD alone; and 10 were suspected of having gastrointestinal disease, but had normal duodenal histology (non-CD controls). Patients with both CD and T1D were examined before and after remission following a gluten-free diet. We performed lectin histochemistry using peanut agglutinin (PNA) and Ulex europaeus agglutinin (UEA) staining for Gal-β(1,3)-GalNAc and Fucι1-2Gal-R, respectively, of the glycocalyx/mucous layer. The staining was scored based on dissemination of stained structures on a scale from 0 to 3. Evaluation of the scores revealed no difference between biopsies obtained before and after remission in the group of children with both CD and T1D. A comparison of this pre-remission group with the children who had CD alone or the non-CD controls also showed no significant differences. Based on our material, we found no indication that the presence of Gal-β(1,3)-GalNAc or Fucι1-2Gal-R is involved in the susceptibility to CD, or that the disease process affects the expression of these carbohydrates
Distinct nature of static and dynamic magnetic stripes in cuprate superconductors
We present detailed neutron scattering studies of the static and dynamic
stripes in an optimally doped high-temperature superconductor,
LaCuO. We find that the dynamic stripes do not disperse towards the
static stripes in the limit of vanishing energy transfer. We conclude that the
dynamic stripes observed in neutron scattering experiments are not the
Goldstone modes associated with the broken symmetry of the simultaneously
observed static stripes, but rather that the signals originate from different
domains in the sample. These domains may be related by structural twinning, or
may be entirely different phases, where the static stripes in one phase are
pinned versions of the dynamic stripes in the other. Our results explain
earlier observations of unusual dispersions in underdoped
LaSrCuO () and LaBaCuO ().
Our findings are relevant for all compounds exhibiting magnetic stripes, and
may thus be a vital part in unveiling the nature of high temperature
superconductivity
Bisexuality, religion and spirituality: instigating a dialogue
This chapter provides a framework and rationale for the edited volume. We argue that although literature on non-normative sexualities continues to grow, bisexuality is still often presented as an appendage. Research on bisexuality in relation to religion and spirituality is even scarcer. Yet, bisexuality, with its focus on fluidity and ambiguity, has the potential to illuminate how gender and sexual binarism impacts upon spiritual and religious life, and how this can be disrupted. Drawing upon key extant literature, this chapter discusses two main themes. Firstly, it explores the dominant discourse of bisexuality in contemporary society. Research continues to evince that bisexuality is grossly misunderstood, due to prevailing ideologies such as monosexism, compulsory coupledom and compulsory monogamy. Indeed, bisexuality fundamentally disrupts hegemonic discourse and enactment of gender and sexuality predicated on binarism. Secondly, the chapter examines the intersection of bisexuality with religion and spirituality. Research literature shows that the outcome of this intersection is complex and multiple. Yet, what is clear is that bisexuality challenges dominant religious discourses on sexuality and gender which results in bisexual erasure. The chapter concludes by presenting summaries of the contributions, framed in relation to the overarching objectives of the volume
