Science Triggers and Situational Interest in Everyday Family Life
ABSTRACT Interest in science is critical for science learning. The family plays a major role in supporting the development of children's interest in science by eliciting and fostering interest and engagement with science content and practice. This study characterizes triggers for interest in science in everyday family life and measures the duration of ...

Fossil Groups Origins: I. RX J105453.3+552102 a very massive and relaxed system at z~0.5
The most accepted scenario for the origin of fossil groups (FGs) is that they are galaxy associations in which the merging rate was fast and efficient. These systems have assembled half of their mass at early epoch of the Universe, subsequently growing ...

Satellite galaxies in nearby groups of galaxies
We analyse distribution, kinematics and star-formation (SF) properties of satellite galaxies in three different samples of nearby groups. We find that studied groups are generally well approximated by low-concentration NFW model, show a variety of LOS velocity dispersion profiles and signs of SF quenching in outskirts of dwarf satellite galaxies.

Tools for Learning—Promoting Reflection for Student Teachers' Development of PCK
ABSTRACT This paper investigates how the coherent integration of three different tools for reflection during a science methods course can contribute to student teachers' planning and enactment of science teaching, that is, their development of pedagogical content knowledge (PCK).

A Hot Core in the Group-dominant Elliptical Galaxy NGC 777
NGC 777 provides an example of a phenomenon observed in some group-central ellipticals, in which the temperature profile shows a central peak, despite the short central cooling time of the intragroup medium.

The Effect of Seductive Details on Knowledge Retention in Physics Videos: A Mixed Methods Study
ABSTRACT Research reports that interesting but irrelevant information, seductive details, in teaching material can impede learning. In science education, the inclusion of historical narratives in lessons to promote interest has been recommended but may hinder learning.

Resource allocation for integrated satellite‐terrestrial networks based on RSMA
We first establish a downlink transmission framework for the integrated satellite‐terrestrial network based on RSMA, to achieve high data rate transmission of virtual reality applications globally. Then, considering some practical constraints, a joint resource allocation problem of rate and transmission power is formulated.

Galaxy groups in the presence of cosmological constant: Increasing the masses of groups
The boundaries of galaxy groups and clusters are defined by the interplay between the Newtonian attractive force and the decoupling from the local expansion of the Universe.
