Beach Gold and Heavy Mineral Concentrates on Tiwai Spit Gravel Strand Plain, Southland, New Zealand
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.The Holocene Tiwai Spit on Foveaux Strait is a 12 km by 2 km gravel‐dominated strand plain, ∼10 m above present sea level. Gravel clasts are dominated by well‐rounded quartz cobbles, pebbles and granules derived from Otago Schist 200 km to the north in evolving river drainage systems during late Cenozoic.

Protein Science, Volume 35, Issue 9, September 2026.Abstract Cryo‐electron tomography (cryo‐ET) enables structural characterization of biomolecules under near‐native conditions. Existing approaches for interpreting the resulting three‐dimensional volumes are computationally expensive and have difficulty interpreting density associated with small proteins/complexes.

Model predictive gust load alleviation for a flexible wing considering system limitations
CEAS Aeronautical JournalFuture aircraft with increasingly flexible high aspect ratio wings are more vulnerable to gust and turbulence encounters. Active control technologies are therefore required to mitigate the effects of atmospheric disturbances and reduce structural ...

Addiction, Volume 121, Issue 9, Page 2504-2517, September 2026.Abstract Background and aims Cocaine use disorder (CUD) is a significant global health concern, characterized by persistent craving despite severe consequences. Recent theories highlight maladaptive memory processes – such as intrusive, vivid recollections of past substance use that arise spontaneously in daily life – as key contributors to craving and

An Unusual Structure for a Feedforward Gust Load Alleviation Controller [PDF]
, 2017 This paper presents an unusual feedforward controller structure that allows to take allocation constraints into account which can be expressed in the time-frequency or time-scale domains. This novel controller structure was motivated by the design of a feedforward controller for airplane gust and turbulence load alleviation based on Doppler LIDAR ...

Decentralized Control of Ailerons for Gust Load Alleviation [PDF]
This paper describes the design of a so-called decentralized gust load alleviation system for an aircraft with high aspect ratio wings. The system uses control loops at each individual aileron actuator that aim to reduce local structural dynamics at each respective point of installation in the wing structure. To this end, each actuator is equipped with

Integrated Optimization of Ailerons for Active Gust Load Alleviation [PDF]
, 2015 An active gust load alleviation (GLA) system offers great potential for weight savings in aircraft design. Its effectiveness, however, strongly depends on the layout of available control surfaces, which is investigated in this paper. For the purpose of wing load reduction, the parameters of a static gain feedback controller are optimized simultaneously
