The Influence of Unplugged LEGO Activities on Middle Grades Students’ Computational Thinking Dispositions in a STEM Camp

Description: Article examines how middle‑grade students engaged in computational thinking dispositions during unplugged LEGO activities in a STEM camp, using case‑study methods with observational notes and participant reflections. Article finds that structured LEGO tasks foster persistence but not tolerance for ambiguity, while semi‑structured tasks support ambiguity tolerance but not persistence, with both formats promoting collaboration—offering practical guidance for educators designing unplugged activit… more

Existence of Two Infinite Families of Solutions For Singular Superlinear Equations On Exterior Domains

Description: In this article the author studies radial solutions of Δu+K(|x|)f(u)=0 in the exterior of the ball radius R>0 in RN with N>2 where f grows superlinearly at infinity and is singular at 0 with f(u)~1/|u|q-1u and 0<q<1 for small u. The author assume K(|x|)∼|x|−α for large |x| and establish existence of two infinite families of sign-changing solutions when N+q(N−2)<α<2(N−1).

Self-Cleaning Highly Porous TiO2 Coating Designed by Swelling-Assisted Sequential Infiltration Synthesis (SIS) of a Block Copolymer Template

Description: This article asserts that photocatalytic self-cleaning coatings with a high surface area are important for a wide range of applications, including optical coatings, solar panels, mirrors, etc. The authors designed a highly porous TiO2 coating with photoinduced self-cleaning characteristics and very high hydrophilicity. This was achieved using the swelling-assisted sequential infiltration synthesis (SIS) of a block copolymer (BCP) template, which was followed by polymer removal via oxidative the… more

Changes in Deep Soil Water Content in the Process of Large-Scale Apple Tree Planting on the Loess Tableland of China

Description: This article evaluates the effects of orchard development on deep soil water content (SWC) by using a meta-analysis of 162 sampling sites on the loess tableland from 44 peer-reviewed publications. The results showed that the deep SWC in orchards depended on stand age, planting density and annual precipitation.

Ordering-mediated local nano-clustering results in unusually large Hall-Petch strengthening coefficients in high entropy alloys

Description: This article reports a dramatic increase in the grain boundary strengthening or Hall-Petch coefficient, K, by systematically investigating the effect of Al addition on tensile yield strength in CoFeNi and CoCrFeNi high entropy alloys (HEAs) or complex concentrated alloys (CCAs). Such a trend is attributed to the ordering mediated nano-clustering in Al containing HEA/CCAs.

Triarchic or Septarchic? - Uncovering the Triarchic Psychopathy Measure’s (TriPM) Structure

Description: This article describes a study conducted to test the structure of the Triarchic Psychopathy Measure (TriPM) via exploratory and confirmatory factor analysis. Findings suggest that the three original TriPM factors do not optimally represent the conceptual model underlying the TriPM.

Artificially structured boundary for confinement of effectively unmagnetized cryogenic antimatter plasmas

Description: The article is from conference proceedings that discuss an artificially structured boundary (ABS) considered to consist of a spatially periodic arrangement of electrostatically plugged magnetic cusps. As envisioned, a non-neutral positron plasma could be confined by an ASB along its edge, and the space charge of the positron plasma would serve to confine an antiproton plasma. If the conditions of the two-species plasma are suitable, production of antihydrogen via three-body recombination for an… more
