Loess Studies in Aotearoa New Zealand
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.Loess in Aotearoa New Zealand (ANZ) has been studied since its first documented recognition (on Banks Peninsula) in 1878 by Julius von Haast. A decade later, John Hardcastle revealed that southern ANZ loess was both glacial in origin and contained signals of past climates.

Calibration‐Free GRAPE pTx Pulses for Homogeneous Spatial‐Selective Excitation at 7T
Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3104-3115, June 2026.ABSTRACT Purpose Extend the universal pulse GRAPE formalism to pulses with a defined spectral response, and apply the concept to spatial selection. Methods We added Bloch simulations at several frequencies for each voxel to the pulse calculation to create universal spectrally‐selective GRAPE pulses.

AGU Advances, Volume 7, Issue 3, June 2026.Abstract In Low Earth Orbit (LEO), atmospheric drag is the dominant source of trajectory prediction error below approximately 700 km altitude, primarily due to inaccuracies in thermospheric density models. This work presents a method for temporally deconvolving Energy Dissipation Rates (EDRs) to produce single‐satellite density estimates, which can be ...

European Journal of Education, Volume 61, Issue 2, June 2026.ABSTRACT This study examines the impact of the Web 2.0‐focused course on preservice science teachers' self‐efficacy in developing digital materials, their tendency to integrate technology into teaching, and views on using technology in teaching practice. We used a sequential explanatory mixed‐method design.

Nanophotonics, Volume 15, Issue 9, 13 May 2026.This perspective surveys emerging quantum and classical photonic applications across operating wavelengths and timescales, highlighting persistent technological gaps in integrated light sources. We examine the unique advantages of quadratic nonlinear photonics on the thin‐film lithium niobate (TFLN) platform and discuss strategies for realizing ...

Experimental methods in chemical engineering: Atomic absorption spectrometry—AAS
The Canadian Journal of Chemical Engineering, Volume 104, Issue 5, Page 2206-2224, May 2026.Abstract Elements absorb electromagnetic radiation (light) of a specific wavelength in proportion to the number of atoms in its path. As the atoms absorb this light energy, electrons rise from the ground state to an excited state. In atomic absorption spectrometry (AAS), high temperatures produce clouds of atoms from the sample (atomization) and ...

Cross‐Site Generalization of CNN‐Based B1+$$ {B}_1^{+} $$ Mapping in UHF MRI
NMR in Biomedicine, Volume 39, Issue 5, May 2026.The study demonstrates that CNN%‐based B1+$$ {B}_1^{+} $$ mapping transfers across sites with only moderate accuracy loss: while on‐site RMSEs were as low as ~3%, cross‐site predictions increased errors but remained qualitatively robust. Despite these deviations, cross‐site maps successfully enabled dynamic 4kT‐points pulses, achieving flip‐angle ...
