MEG Evidence of Concurrent Bilateral and Hemisphere‐Specific Developmental Patterns in Auditory Cortex

Developmental Science, Volume 29, Issue 3, May 2026.
ABSTRACT Children demonstrate remarkably different temporal characteristics, as well as higher interindividual variability, in the cortical auditory responses as compared with adults. The detailed dynamics at the level of underlying current generators are, however, not established.

Thermal magnetization transport analysis featuring darcian and multi-physical rheological characteristics in chemically reactive dual convective tangent-hyperbolic nanomaterial confined by vertical cone

Case Studies in Thermal Engineering
The Soret-Dufour characteristics elaborate the phenomena of cross-diffusion where solutal gradients yield heat flux (Dufour aspect) and thermal gradients engender mass flux (Soret effect).

Seismic Design of Concrete Dams: An Integrated Risk‐Informed Performance‐Based (RIPB) Framework

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 5, Page 1019-1049, 25 April 2026.
ABSTRACT This paper advances the integration of risk‐informed principles into the seismic design of dams—a domain long guided by standards‐based, largely deterministic approaches. While performance‐based earthquake engineering is well established for buildings and bridges, its systematic adoption in dam engineering remains limited. We first address two

Large Deformation Pile‐soil Interaction Under Lateral Vehicle Impact Using Hybrid SPH+FEM and EFG+FEM Models

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 5, Page 2648-2669, 10 April 2026.
ABSTRACT This study presents large deformation computational methods to simulate lateral vehicular impacts on steel piles in granular soil. Soil‐mounted longitudinal barrier systems rely on energy dissipation in both the piles and the surrounding soil to safely redirect errant vehicles, so dynamic pile‐soil interaction is important for design ...

Prosthetic Emergence Angles and Implant Outcomes: A Retrospective Study With at Least 5 Years of Follow‐Up

Clinical Implant Dentistry and Related Research, Volume 28, Issue 2, April 2026.
ABSTRACT Objectives The influence of prosthetic emergence angles on peri‐implant tissue stability has become a topic of growing interest. While wide emergence angles have been associated with increased marginal bone loss (MBL) and peri‐implantitis, available evidence is limited and largely based on studies using prefabricated abutments.

Anisotropic Cellular Forces Drive Hexagonal‐to‐Tetragonal Tiling Transitions in the Drosophila Eye

Development, Growth &Differentiation, Volume 68, Issue 3, April 2026.
ABSTRACT Tile patterns are fundamental organizational principles of multicellular epithelial tissues. The Drosophila compound eye provides a striking example, in which ommatidia are arranged in a highly regular hexagonal lattice, while tetragonal patterns emerge in specific small‐eye mutants.

Observation of Mountain Waves and Secondary Gravity Waves in the Mesosphere Lower Thermosphere Above Patagonia

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract We find observational evidence for mountain waves (MWs) and secondary gravity waves (2GWs) in the OH*(3‐1) layer above Tierra del Fuego, Argentina. On the night of 21–22 May 2018, the Advanced Mesospheric Temperature Mapper (AMTM) obtained temperatures at ∼84 ${\sim} 84$ km.

Dosimetric effects of internal margin, auto flash, and virtual bolus in VMAT‐based whole‐breast radiotherapy under motion variations

Journal of Applied Clinical Medical Physics, Volume 27, Issue 3, March 2026.
Abstract Background and purpose This study aimed to evaluate the dosimetric performance and robustness of volumetric modulated arc therapy (VMAT) planning techniques—planning target volume with internal margin (INT), auto flash (AF), and virtual bolus (VB)—under simulated geometric changes during whole‐breast radiotherapy.
