Cosmological model with local symmetry of very special relativity and constraints on it from supernovae

open access: yes, 2013
Based on Cohen \& Glashow's very special relativity [A. G. Cohen and S. L. Glashow, Phys. Rev. Lett. {\bf 97} (2006) 021601], we propose an anisotropic modification to the Friedmann-Robertson-Walker (FRW) line element.

Weak H‐Bonds of Fluorophenyl Synthons Enabling Efficient and Entropically Stabilized Supramolecular Electro‐Optic Dendrimers

open access: yesChemPhotoChem, Volume 9, Issue 10, October 14, 2025.
Weak hydrogen bonding interactions in singular fluorophenyl synthons enable efficient and entropically stabilized supramolecular electro‐optic (EO) dendrimers. It demonstrates the highest effective EO activity reported to date for dendrimers measured by attenuated total reflection certification, low optical losses, and improved sub‐T g temporal ...

Constraints on spacetime anisotropy and Lorentz violation from the GRAAL experiment

open access: yes, 2013
The GRAAL experiment could constrain the variations of the speed of light. The anisotropy of the speed of light may imply that the spacetime is anisotropic. Finsler geometry is a reasonable candidate to deal with the spacetime anisotropy.

Definisi dan Keterkaitan Mantuq dan Mafhum, Dzahir dan Mu’awwal, Nasakh, Muradif dan Musytarak

open access: yesMandub : Jurnal Politik, Sosial, Hukum dan Humaniora
The study of ushul fiqh is very closely related to the Koran and Sunnah. Both of them are the core sources of Islamic sharia law which are used as proof which are processed by ushuliyah rules in determining sharia laws. This research aims to explain the essence of Ushuliyyah rules, especially regarding Mantuq and Mafhum, Dzahir and Mu'awwal, Nasakh ...

Advances and Outlook of Nickel‐Based MOFs–LDHs Materials for Energy Conversion

open access: yesAdvanced Sustainable Systems, Volume 9, Issue 9, September 2025.
In this graphical abstract, we present the pivotal gap between the activity and stability parameters as far as intergrated Ni‐based MOF/LDF electrocatalysts are concerned. For large scale application, these two parameters should be optimized and furthermore balanced in order to promote sustainable electrocatalytic hydrogen production.

Verdier, engasjement og tilhørighet som drivkrefter i lærerstudenters yrkesvalg og utvikling av læreridentitet

open access: yesNordisk tidsskrift for pedagogikk og kritikk, 2016
Little research has been done in Norway about what motivates students to choose a career in teaching. This is a qualitative study aimed at examining students’ motivation for becoming teachers, as well as examining if the Teacher Education program of ...

Exploring Characteristics of Emerging Nature Education Practices in China: Content Analysis of Lesson Plans 《探索中国新兴自然教育实践的特征:课程计划的内容分析》

open access: yesIntegrative Conservation, Volume 4, Issue 3, Page 322-333, September 2025.
A content analysis of 154 nature education lesson plans from China showed that educators designed diverse programs tailored to age‐specific developmental and social needs. Most focused on personal growth, such as cognitive development, mental well‐being, and family bonding, but few explicitly addressed environmental conservation goals.

Epigenetic regulation of lignin biosynthesis in wood formation

open access: yesNew Phytologist, Volume 245, Issue 4, Page 1589-1607, February 2025.
Summary Lignin, a major wood component, is the key limiting factor for wood conversion efficiency. Its biosynthesis is controlled by transcriptional regulatory networks involving transcription factor (TF)–DNA interactions. However, the epigenetic mechanisms underlying these interactions in lignin biosynthesis remain largely unknown.
