Analysis on Noncompact Manifolds and Index Theory: Fredholm Conditions and Pseudodifferential Operators
We provide Fredholm conditions for compatible differential operators on certain Lie manifolds (that is, on certain possibly non-compact manifolds with nice ends). We discuss in more detail the case of manifold...

Neurological manifestations of adult-onset Still’s disease—case-based review
Adult-onset Still’s disease (AOSD) is a rare inflammatory disorder in which pathophysiology is yet to be fully understood. We report the case of a 66-year-old male that presents with fever, arthralgia, and lab...

Assessment of Poor Inhaler Technique in Older Patients with Asthma or COPD: A Predictive Tool for Clinical Risk and Inhaler Performance
Older patients with asthma or chronic obstructive pulmonary disease (COPD) are particularly susceptible to inhaler technique errors and poor clinical outcomes. Several factors may influence their risk, but mos...

A Multi-dataset Approach for DME Risk Detection in Eye Fundus Images
Diabetic macular edema is a leading cause of visual loss for patients with diabetes. While diagnosis can only be performed by optical coherence tomography, diabetic macular edema risk assessment is often perfo...

Metastasis is impaired by endothelial-specific Dll4 loss-of-function through inhibition of epithelial-to-mesenchymal transition and reduction of cancer stem cells and circulating tumor cells
Systemic inhibition of Dll4 has been shown to thoroughly reduce cancer metastasis. The exact cause of this effect and whether it is endothelial mediated remains to be clarified. Therefore, we proposed to analy...

Fredholm Conditions on Non-compact Manifolds: Theory and Examples
We give explicit Fredholm conditions for classes of pseudodifferential operators on suitable singular and non-compact spaces. In particular, we include a “user’s guide” to Fredholm conditions on particular cla...

Cortical bone analysis in a predialysis population: a comparison with a dialysis population
This study was designed to characterize cortical bone by histomorphometry in a predialysis population, to correlate turnover, mineralization, and volume between cortical and trabecular bone, and to compare the...

The role of bone biopsy for the diagnosis of renal osteodystrophy: a short overview and future perspectives
Chronic kidney disease (CKD) patients present specific bone and mineral metabolism disturbances, which account for important morbidity and mortality. The term renal osteodystrophy, classically used for the nom...

An Index Formula for Perturbed Dirac Operators on Lie Manifolds
We prove an index formula for a class of Dirac operators coupled with unbounded potentials, also called “Callias-type operators”. More precisely, we study operators of the form

Layer potentials C*-algebras of domains with conical points
To a domain with conical points Ω, we associate a natural C*-algebra that is motivated by the study of boundary value problems on Ω, especially using the method of layer potentials. In two dimensions, we allow Ω ...

Regularity for Eigenfunctions of Schrödinger Operators
We prove a regularity result in weighted Sobolev (or Babuška–Kondratiev) spaces for the eigenfunctions of certain Schrödinger-type operators. Our results apply, in particular, to a non-relativistic Schrödinger...

On Maltsev Digraphs
We study digraphs preserved by a Maltsev operation, Maltsev digraphs. We show that these digraphs retract either onto a directed path or to the disjoint union of directed cycles, showing that the constraint sa...

CD(4) has bounded width
We prove that the constraint languages invariant under a short sequence of Jónsson terms (containing at most three non-trivial ternary terms) are tractable by showing that they have bounded width. This improve...
