Conversion Between 2‐ and 3‐Dimensional Halogen‐Bonded Networks Formed From a Single N‐Oxide/Iodoalkyne Building Block

open access: yesChemistry – A European Journal, EarlyView.
Open halogen‐bonded networks have been prepared from building blocks that incorporate both iodoalkyne halogen bond donors and a pyridine‐N‐oxide halogen bond acceptor. An initially‐formed 3D network containing dioxane in its channels undergoes an unprecedented transition to a 2D material when crystals are exposed to diethyl ether.

Evaluation of Static Potential Integrals on Triangular Domains

open access: yesIEEE Access, 2020
Static potential integrals for constant and linear sources on triangles are derived in a straightforward way. The new representations, as presented, are robust with respect to machine evaluation in important limiting cases.

Hydration of an apolar solute in a two-dimensional waterlike lattice fluid

open access: yes, 2005
In a previous work, we investigated a two-dimensional lattice-fluid model, displaying some waterlike thermodynamic anomalies. The model, defined on a triangular lattice, is now extended to aqueous solutions with apolar species. Water molecules are of the

Habitat complexity and prey composition shape an apex predator's habitat use across contrasting landscapes

open access: yesEcography, EarlyView.
The spatial ecology of stalk‐and‐ambush predators like the Eurasian lynx Lynx lynx depends on prey availability and environmental features, yet the relative roles of these factors remain unclear at large spatial scales. In this study, we analysed lynx habitat use across central and southern Finland using snow‐track data from the Wildlife Triangle ...

Decacarbonyl-1κ3C,2κ3C,3κ4C-μ-hydrido-1:2κ2H:H-(μ-quinoline-2-thiolato-1:2κ2S:S)diosmium(I)osmium(0)(3 Os—Os)

open access: yesActa Crystallographica Section E, 2008
The title compound, [Os3(C9H6NS)H(CO)10], contains a nearly equilateral triangle of Os atoms. Two of the Os atoms are bridged by an S atom of the quinoline-2-thiolate ligand.

Stereo‐EEG mapping of visual working memory with task‐related high‐gamma modulations

open access: yesEpilepsia, EarlyView.
Abstract Objective We describe a safe, informative, and easy‐to‐implement approach for presurgical mapping of visual working memory (VWM) with stereo‐electroencephalography (SEEG). Methods Twenty‐four patients with drug‐resistant epilepsy, 11–23 years of age, performed a single‐probe change detection VWM task, during SEEG monitoring.

Optimum oil palm planting density in West Africa

open access: yesOilseeds and fats, crops and lipids, 2018
This article follows on from an earlier one about the same experiment in 2014. A range of various planting distances (from 7.5 to 9.5 metres) between oil palms was tested using an equilateral triangle design.

On the Einthoven Triangle: A Critical Analysis of the Single Rotating Dipole Hypothesis

open access: yesSensors, 2018
Since its inception, electrocardiography has been based on the simplifying hypothesis that cardinal limb leads form an equilateral triangle of which, at the center/centroid, the electrical equivalent of the cardiac activity rotates during the cardiac ...

Wave Propagation in Periodic Metallic Structures with Equilateral Triangular Holes

open access: yesApplied Sciences, 2020
This paper studies wave propagation in a periodic parallel-plate waveguide with equilateral triangular holes. A mode-matching method is implemented to analyze the dispersion diagram of the structure possessing glide and mirror symmetries. Both structures

Closed almost-periodic orbits in semiclassical quantization of generic polygons

open access: yes, 2000
Periodic orbits are the central ingredients of modern semiclassical theories and corrections to these are generally non-classical in origin. We show here that for the class of generic polygonal billiards, the corrections are predominantly classical in ...
