From Friends to Foes? Negative Campaign Tactics on Facebook and Their Effects on User Engagement Across Three National Elections in Sweden (2014–2022)

Scandinavian Political Studies, Volume 49, Issue 3, August 2026.
ABSTRACT Research has documented an increase in the use of negative campaign strategies during election campaigns worldwide. This study contributes to the literature by offering a longitudinal analysis of how negative statements and moral scandalization strategies by Swedish political parties on Facebook have evolved over time, and whether they ...

Uncertainty Quantification of Analytical Solutions for the Nonlinear Space and Time Fractional Order ϕ4$$ {\phi}^4 $$ Equation Under Fuzziness

Engineering Reports, Volume 8, Issue 7, July 2026.
Analytical fuzzy soliton solutions of a modified space–time fractional ϕ4$$ {\phi}^4 $$ model are derived using EHFM, capturing memory effects and uncertainty. Results reveal diverse wave structures and show how fractional order and fuzziness significantly influence soliton amplitude, localization, and propagation, with heightened sensitivity near the ...

Connections of zero curvature and Bäcklund transformations

, 2015
Zero curvature connections in a principal bundle are introduced. It is shown that such connections are very useful in formulating the Bäcklund problem and in constructing transformations.

Lie symmetry analysis for generalized short pulse equation

Open Physics, 2022
Lie symmetry analysis (LSA) is one of the most common, effective, and estimation-free methods to find the symmetries and solutions of the differential equations (DEs) by following an algorithm.

Pathways to increased attendance: Young people's experiences of turning absence to attendance in school

Journal of Research in Special Educational Needs, Volume 26, Issue 3, July 2026.
Abstract School attendance problems (SAPs) have received increased attention internationally in recent years; however, there are still few qualitative studies that explore attendance promotion from the perspective of young people with such experiences and who have managed to increase their attendance.

Preferences for Blood Glucose Management in Adult Intensive Care Unit Patients—An International Survey

Acta Anaesthesiologica Scandinavica, Volume 70, Issue 6, July 2026.
ABSTRACT Introduction Hyperglycaemia is common in intensive care unit (ICU) patients and blood glucose management practices likely vary, but there are limited contemporary data on ICU doctors' and nurses' preferences. Methods We conducted an international online survey of ICU doctors and nurses. The 16‐question survey covered respondent characteristics,

Parkinson's Disease Cell Transplantation Therapy: A New Dawn With Pluripotent Stem Cell–Based Therapy

Journal of Neurochemistry, Volume 170, Issue 7, July 2026.
Parkinson's disease (PD) is characterized by the progressive loss of dopaminergic neurons in the midbrain. Cell transplantation, which aims to replace these lost neurons, has emerged as a promising approach. Early attempts using fetal ventral mesencephalic tissue showed proof‐of‐concept, with some patients achieving long‐term motor improvement. However,

Bäcklund Transformations for the Trigonometric Gaudin Magnet

Symmetry, Integrability and Geometry: Methods and Applications, 2010
We construct a Bäcklund transformation for the trigonometric classical Gaudin magnet starting from the Lax representation of the model. The Darboux dressing matrix obtained depends just on one set of variables because of the so-called spectrality ...
