The title compound, octaaqua-(hydrogendifluorido)-di-cop-per(II) hexa-fluoridoaluminate dihydrate, was obtained under hydro-thermal conditions. The structure is isotypic with that of the analogous Fe(III) compound, [Cu(2)(HF(2))(H(2)O)(8)][FeF(6)]·2H(2)O. The coordination sphere of the Cu(II) atom is formed by one F and three water O atoms at short distances < 2 Å and is augmented by two additi...

We discuss the representation theory of Hf , which is a deformation of the symplectic oscillator algebra sp(2n) ⋉ hn, where hn is the ((2n+1)-dimensional) Heisenberg algebra. We first look at a more general algebra with a triangular decomposition. Assuming the PBW theorem, and one other hypothesis, we show that the BGG category O is abelian, finite length, and self-dual. We decompose O as a dir...

Enthusiast’s perspective: We analyze the effectiveness of AQC for a small rank problem Hamiltonian HF with the arbitrary initial Hamiltonian HI . We prove that for the generic HI the running time cannot be smaller than O( √ N), where N is a dimension of the Hilbert space. We also construct an explicit HI for which the running time is indeed O( √ N). Our algorithm can be used to solve the unstru...

Two types of cupric oxide (Cu₂O) nanoarchitectures (nanobelts and nanopetal networks) have been achieved via immersion nanoporous copper (NPC) templates in anhydrous ethanol. NPC templates with different defect densities have been prepared by dealloying amorphous Ti60Cu40 ribbons in a mixture solution of hydrofluoric acid and polyvinylpyrrolidone (PVP) with different ratios of HF/PVP. Both a wa...

Heart failure (HF) is one of the most prevalent conditions worldwide and despite therapeutic advances, its prognosis remains poor. Among the multiple comorbidities in HF, sleep-disordered breathing (SDB) is frequent and worsens the prognosis. Preliminary observational studies suggested that treatment of SDB could modify the prognosis of HF, and the issue has gained importance in recent years. T...

The distribution coefficient (Kd) of Rf on ion exchange resins at various HNO3/HF concentrations had been studied [1]. Rf was eluted at higher HF concentrations from CIX than Zr and Hf and rather resembled Th. Up to 1 M HF, Rf was not retained on the AIX also resembling its pseudo-homolog Th. Th is known to form no anionic fluoride complexes, while Zr and Hf are forming complexes of the type [M...

صخلملا Seasonal variation of zooplankton biomass has been carried out at two selected sites on Greater Zab River. Monthly samples of water were collected during period from January to December 2008. Some physico-chemical properties of water were studied including water temperature (from 8 to 30.5 C), hydrogen ion concentration (from 6.3 to 8), EC (from 255 to 821 μs.cm), turbidity (1085 NTU), d...

Chemoreflex control of sympathetic nerve activity is exaggerated in heart failure (HF) patients. However, the vascular implications of the augmented sympathetic activity during chemoreceptor activation in patients with HF are unknown. We tested the hypothesis that the muscle blood flow responses during peripheral and central chemoreflex stimulation would be blunted in patients with HF. Sixteen ...
