Comparing technology-enhanced and conventional Van Hiele Phased Instruction in advancing learners through Van Hiele levels in transformation geometry

open access: yesCogent Education
Developing learners’ geometric reasoning remains a persistent challenge in secondary mathematics education, particularly in transformation geometry, where many learners struggle to progress through the hierarchical Van Hiele levels of geometric thinking.

A 3D‐Printed SFE‐Graded Alloy Mitigates Cryogenic Discontinuous Plastic Flow and Hydrogen Embrittlement

open access: yesAdvanced Science, EarlyView.
A novel strategy features gradient composition and stacking fault energy‐tuned (CoCrMn)100‐2xFexNix fabricated via in situ alloying additive manufacturing. This design circumvents cryogenic discontinuous plastic flow and hydrogen embrittlement of metallic materials under quasi‐static loading and hydrogen‐rich environment relevant to lunar polar ...

Sodiophilic Na3Sb Framework‐Regulated Sodium Deposition and Interphase Evolution for Dendrite‐Free and Long‐Life Sodium Metal Batteries

open access: yesAdvanced Science, EarlyView.
An interconnected sodiophilic Na3Sb framework embedded within a metallic Na matrix enables uniform Na deposition by homogenizing Na+ flux and providing abundant nucleation sites. Simultaneously, the regulated interface promotes the formation of a stable, NaF‐rich inorganic interphase, collectively suppressing dendrite growth and enabling highly ...

Recent Tectonic Deformation of the Lunar Farside Mare and South Pole–Aitken Basin

open access: yesThe Planetary Science Journal
The timing and scale of lunar tectonism provide a crucial insight into the geologic evolution of Earth’s Moon. Within the nearside lunar maria, wrinkle ridges formed during and after the emplacement of the mare basalts as a result of subsidence-induced ...

SLC25A4high Hepatocytes Enhance Lifestyle Intervention Response in MASLD by Recruiting Eating Macrophages

open access: yesAdvanced Science, EarlyView.
SLC25A4high hepatocytes drive metabolic‐associated steatotic liver disease (MASLD) remission by recruiting lipid‐eating macrophages. The hepatocyte Slc25a4/PANX1/ATP/P2ry12 axis mediates find‐me signaling that triggers macrophage recruitment and efferocytosis, while recruited macrophages secrete GDF15 to activate hepatocyte PPARα and promote fatty acid

Probing Lateral Density Variations in the Crust from Gravity and Topography: Applications to the Moon and Mars

open access: yesThe Planetary Science Journal
We present a constraint matrix to be used in the determination of gravity field models from spacecraft tracking data that uses information from topography and that allows for the direct determination of lateral variations in crustal density. Our approach

Developmentally Guided Differentiation of Ventral Midbrain Dopaminergic Cells Validated in Proteopathy‐Based Parkinson's Disease Models

open access: yesAdvanced Science, EarlyView.
A developmentally guided protocol reproducibly specifies EN1‐positive ventral midbrain dopaminergic (vmDA) progenitors from human pluripotent stem cells and yields functional vmDA neurons. Optogenetic induction of α‐synuclein aggregation elicits selective degeneration of TH‐positive neurons in 2D cultures and 3D neurospheroids, while transplanted ...

Physics‐Guided Multi‐Channel Restoration for Efficient and Accurate Atomic Force Microscopy Imaging

open access: yesAdvanced Science, EarlyView.
Schematic figure of restoring noisy atomic force micrscopy (AFM) image via physics‐guided multi‐channel restoration. The lighter neural network models with multiple‐channel input from auxiliary signals outperforms heavier model with single‐channel input.
