Fundamental solutions and eigenfunction expansions for Schr�dinger operators I. Fundamental solutions

open access: yesMathematische Zeitschrift, 1988
This is the first part of a series of papers dealing with eigenfunction expansions for the Schrödinger operator \(H=H_ 0+V(x)\), \(H_ 0=- \Delta /2\), where we assume V(x)\(\in {\mathcal B}^{\infty}(R^ n)\) is real-valued, \({\mathcal B}^{\infty}(R^ n)\) denoting the space of smooth functions on \(R^ n\) with bounded derivatives. In this part, we first

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

EXPLICIT ESTIMATION OF AN INTEGRAL IN A DOMAIN BY THE MULTIPLE RECIPROCITY METHOD WITH THE USE OF INVERSE OPERATIONS

open access: yesTASK Quarterly, 2005
The paper presents two methods of solving the Poisson equation. One is based on the multiple reciprocity method. An analytical form of the basic solution obtained by means of inverse operation technique enabled assessing the method’s error. The other is

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Extrapolating an Euler class [PDF]

open access: yes, 2015
Let R be a noetherian ring of dimension d and let n be an integer so that n≤d≤2n-3. Let (a1,..., an+1) be a unimodular row so that the ideal J=(a1,..., an) has height n.

If fundamental movement skills are part of the solution, what is the problem?

open access: yes, 2015
Fundamental Movement Skills (FMS) represent an area of contestation due to multiple interpretations. There is general agreement that their development is significant in shaping student engagement and enjoyment of ‘physical activity’.

Boundary value problems of steady vibrations in the theory of thermoelasticity for materials with a double porosity structure

open access: yesArchives of Mechanics, 2017
The purpose of the present paper is to develop the classical potential method in the linear theory of thermoelasticity for materials with a double porosity structure based on the mechanics of materials with voids.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

open access: yesFEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...
