Precise modelling of switching and conduction losses in cascaded h-bridge multilevel inverters [PDF]

open access: yes, 2014
Nowadays, voltage source multilevel inverters are being used extensively in industry due to its many advantages, compared to conventional two level inverters, such as higher output voltage at low switching frequency, low voltage stress(dv/dt), lower ...

The Effect of Regioisomerism on the TADF Properties of Organic Dyes

open access: yesChemistryEurope, Volume 3, Issue 5, September 18, 2025.
The properties of TADF emitters are highly dependent on the chosen electron donor and acceptor, as well as the π‐system that links them together. Herein, we show that regioisomerism affects the physical properties of spirobifluorene‐based systems in solution, thin films and crystals.

Synthesis, Characterization, and Electrochemical Properties of Tri‐ and Tetranuclear CoIII‐Oxo Complexes

open access: yesEuropean Journal of Inorganic Chemistry, Volume 28, Issue 24, August 29, 2025.
A series of three tetranuclear and two trinuclear Co(III) carboxylate complexes are synthesized and thoroughly spectroscopically and electrochemically characterized. The relative stability of the tetranuclear versus trinuclear complexes is investigated by density functional theory calculations, and the infrared and ultraviolet/visible spectra are ...

Primary Spaces, Mackey's Obstruction, and the Generalized Barycentric Decomposition [PDF]

open access: yes, 2013
We call a hamiltonian N-space \emph{primary} if its moment map is onto a single coadjoint orbit. The question has long been open whether such spaces always split as (homogeneous) x (trivial), as an analogy with representation theory might suggest.

Complex population genetic structure of the bark beetle predator Thanasimus formicarius (L.) (Coleoptera: Cleridae) across its European range

open access: yesAgricultural and Forest Entomology, Volume 27, Issue 3, Page 437-451, August 2025.
Abstract Thanasimus formicarius (L.) (Coleoptera: Cleridae) is an important bark beetle predator and can reduce bark beetle population densities of some of the most severe forest pests in Europe. We analysed the population genetics and phylogeography of T.

High‐pressure crystal structure of n‐hexylamine

open access: yesActa Crystallographica Section C, Volume 81, Issue 6, Page 346-350, June 2025.
The high‐pressure crystal structure of n‐hexylamine remains isostructural with its low‐temperature phase. The compressibility of the N—H…N hydrogen bonds has been analyzed in relation to the shortest C—H…N and H…H intermolecular distances.A primary amine, n‐hexylamine (HA, C6H15N), has been studied at high pressure by single‐crystal X‐ray diffraction ...

Algebras related to posets of hyperplanes [PDF]

open access: yes, 2000
We compare two noncommutative algebras which are related to arrangements of hyperplanes. For three special arrangements the induced approximately finite dimensional $C^*$-algebra and the graded Orlik-Solomon-algebra are ...

Do Intravenous Butaphosphan and Cyanocobalamin Combination Affect Insulin Resistance and Metabolic Profile of Dairy Goats During Their Transition Period?

open access: yesVeterinary Medicine and Science, Volume 11, Issue 1, January 2025.
This study was designed to answer whether butaphosphan and cyanocobalamin affect insulin resistance in transition dairy goats. This combination with prescribed amounts and frequency did not have a significant effect on the metabolic indices of dairy goats but enhanced their insulin responsiveness.
