Loess Studies in Aotearoa New Zealand

open access: yesNew 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.

Regulatory Framework and Public Policies for Sustainability in the Construction Sector

open access: yesSustainable Development, Volume 34, Issue 3, Page 3229-3248, June 2026.
ABSTRACT This study analyzes the role of public policies in promoting socially responsible practices in the construction sector, with a particular focus on their contribution to climate neutrality and the decarbonization of the building stock. European agreements exert increasing pressure to transform the construction sector, reinforcing the transition

Selective Solar CO2 Conversion into Ethanol Using Atomic‐Scale Copper Clusters Anchored π‐extended Poly(heptazine imide)

open access: yesSmall, Volume 22, Issue 32, 8 June 2026.
Atomic‐scale copper clusters anchored on π‐extended poly(heptazine imide) enable selective, sacrificial‐agent‐free solar conversion of carbon dioxide (CO2) to ethanol. The catalyst promotes interfacial charge separation and stabilizes key carbon‐carbon coupling intermediates, providing a molecularly defined platform for direct C2 fuel synthesis under ...

Analysis of Dam Characteristics and Failure Trend of Landslide Dams With Different Materials: Field Investigation

open access: yesWater Resources Research, Volume 62, Issue 6, June 2026.
Abstract Landslides can block rivers and create natural dams that pose significant flooding hazards to upstream and downstream. Variations in dam materials and geometries play a critical role in controlling breach initiation and failure processes, thereby complicating failure assessment.

Bayesian Decision Thresholds for Bushfire Warnings: Calibration and Robustness for Rare‐Event Risk

open access: yesAustralian &New Zealand Journal of Statistics, Volume 68, Issue 2, June 2026.
ABSTRACT Current bushfire warning systems communicate the probability of a warning given danger, but residents require the probability of danger given a warning. This misalignment, combined with the extreme rarity of catastrophic fires, often leads to the dangerous ‘wait and see’ behaviour.

Sleep Deprivation in Mice: Looking Beyond the Slow Wave Rebound

open access: yesJournal of Sleep Research, Volume 35, Issue 3, June 2026.
ABSTRACT Sleep is a fundamental process supporting the dynamic regulation of neural function. Emerging methods have proposed that the aperiodic components of brain signals (such as the spectral slope, spectral intercept, and spectral knee), in addition to entropy‐based measures, offer robust empirical markers of neural states.

Elliptic-Möbius S-boxes: A hybrid algebraic construction for cryptographic applications

open access: yesAlexandria Engineering Journal
Substitution boxes (S-boxes) are the nonlinear core of block ciphers, and their design critically impacts resistance against cryptanalytic attacks. Existing approaches either use chaotic maps, which often exhibit structural weaknesses, or elliptic curve (

Construction of Robust Lightweight S-Boxes Using Enhanced Logistic and Enhanced Sine Maps

open access: yesIEEE Access
Substitution boxes (S-Boxes) are essential elements of modern block ciphers, serving as non-linear characteristics that enhance the resistance of these ciphers against cryptanalysis.

Dynamic S-box construction based on a novel chaotic map and twitching approach

open access: yesMehran University Research Journal of Engineering and Technology
The increasing frequency of hacking and phishing assaults has made data encryption and information security as major solutions. Attackers are concentrating on breaking cryptosystems to obtain valuable data and information.
