Steiner triple systems with rotational automorphisms

open access: yes, 1981
A Steiner triple system S(υ) of order υ is said to be k-ratational (k positive integer) if it admits an automorphism consisting of a single fixed point and precisely k (υ−1)⧸k-cycles.

Effect of repeated hot water immersion on cognitive performance, cerebrovascular function, sleep and biomarkers of neurodegeneration in older adults

open access: yesExperimental Physiology, EarlyView.
Abstract Ageing is associated with cognitive decline and increased risk of developing neurodegenerative disease. Repeated passive heating, using hot water immersion (HWI), may improve cognitive performance via improved cerebral oxygenation, but this is yet to be examined in older adults.

Low‐threshold cutaneous mechanoreceptors on the foot sole have enhanced sensitivity when skin temperature is elevated

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic illustration of microneurography recordings used to examine the effects of local skin heating on cutaneous mechanoreceptor responses in the human foot (left panel). A microelectrode inserted into a peripheral nerve records single‐unit activity from tactile afferent fibres while controlled mechanical stimuli are applied ...

Sets of three pairwise orthogonal Steiner triple systems

open access: yes, 2003
Two Steiner triple systems (STS) are orthogonal if their sets of triples are disjoint, and two disjoint pairs of points defining intersecting triples in one system fail to do so in the other. In 1994, it was shown (Canad. J. Math.

Broadening the semiaquatic scene: Quantification of long bone microanatomy across pinnipeds

open access: yesThe Anatomical Record, Volume 309, Issue 8, Page 2124-2150, August 2026.
Abstract Investigations of bone microanatomy are commonly used to explore lifestyle strategies in vertebrates. While distinct microanatomical limb bone features have been established for exclusively aquatic and terrestrial lifestyles, identifying clear patterns for the semiaquatic lifestyle remains more challenging.

Steiner triple systems and cycle structure

open access: yes
Since 1847 when Rev. T.P. Kirkman published his first paper [24], research in Steiner triple systems has grown steadily. With increased and ready access to more powerfiul computers in recent times, this growth has accelerated significantly.

On the maximal number of pairwise orthogonal Steiner triple systems

open access: yes, 1975
For some time it has been known that for prime powers pk = 1 + 3 · 2st there exists a pair of orthogonal Steiner triple systems of order pk. In fact, such a pair can be constructed using the method of Mullin and Nemeth for constructing strong starters ...

Marine Aerosol to Refinery Emissions: Transport and Evolution of CCN in the Houston Metropolitan Area and Their Impact on Cloud Formation

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract The Experiment of Sea Breeze Convection, Aerosols, Precipitation and Environment (ESCAPE) campaign aimed to untangle the impacts of contrasting aerosol sources on cloud microphysical properties within deep convective cells using airborne observations with the National Research Council Canada (NRC) Convair CV‐580 research aircraft.

Electrically Responsive Structural‐Color Materials

open access: yesAggregate, Volume 7, Issue 7, July 2026.
This review highlights electrically responsive structural‐color materials as next‐generation electrochromic platforms, summarizing key structural designs, modulation mechanisms, and performance metrics to enable continuous, low‐voltage, and tailorable color tuning for advanced display, camouflage, and security applications.

Silencing the Signal: The Metastasis Suppressor NDRG1 Disrupts Small Extracellular Vesicle‐Mediated Crosstalk in Pancreatic Cancer

open access: yesJournal of Extracellular Vesicles, Volume 15, Issue 7, July 2026.
NDRG1 suppresses pancreatic cancer progression by disrupting small extracellular vesicle biogenesis, altering cargo composition, and inhibiting EV uptake by cancer cells—thereby impairing tumour–stroma communication and fibrotic activation. This study reveals NDRG1 as a novel regulator of extracellular vesicle dynamics and a promising therapeutic ...
