Molecular phylogenetics of Thymelaeaceae‐Thymelaeoideae: Resolving the paraphyly of Gnidia and a new monophyletic generic classification for the group

TAXON, Volume 75, Issue 4, August 2026.
Abstract Earlier phylogenetic analyses of the family Thymelaeaceae using combined plastid (matK, rbcL, rps16, trnL‐F) and nuclear (ITS) regions showed that the African‐Malagasy genus Gnidia was extensively polyphyletic in relation to the southern African genera Lachnaea, Passerina and Struthiola, as well as to other Southern Hemisphere genera such as ...

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 ...

Darboux transformation with dihedral reduction group [PDF]

, 2014
We construct the Darboux transformation with Dihedral reduction group for the 2-dimensional generalisation of the periodic Volterra lattice. The resulting Bäcklund transformation can be viewed as a nonevolutionary integrable differential difference ...

Bäcklund Transformation for Solving a (3+1)-Dimensional Integrable Equation

Axioms
A new generalized (3+1)-dimensional Kadomtsev–Petviashvil (3dKP) equation is derived from the inverse scattering transform method. This equation can be reduced to the standard KP equation and the well-know (3+1)-dimensional equation. In making use of the

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 ...

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.

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.

The symmetry breaking solutions of the nonlocal Alice–Bob B-type Kadomtsev–Petviashvili system

Results in Physics, 2023
The (2+1)-dimensional B-type Kadomtsev–Petviashvili equation is an integrable model, which can be used to describe the shallow water wave in a fluid. In this paper, the nonlocal Alice–Bob B-type Kadomtsev–Petviashvili system is induced via the principle ...

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,
