The spectrum features of UHECRs below and surrounding GZK

The energy spectrum of UHECRs is discussed on the basis of the Yakutsk array database analysis. In the region E=0.1 to 30 EeV the showers are detected under trigger-500, while at energies above 30 EeV the whole acceptance area for trigger-1000 is used in order to utilize all the data available in the region of GZK cutoff.Comment: Invited talk at CRIS2004: GZK and surroundings, Catania, Italy, 31.05.04.

Risk profiles and one-year outcomes of patients with newly diagnosed atrial fibrillation in India: Insights from the GARFIELD-AF Registry.

BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.

Synthesis and crystal structure of the copper(II) valerate complex with nicotinamide

A coordination compound of copper(II) valerate with nicotinamide, [CuL(C4H9COO)2]2 (I), has been synthesized, and its crystal structure has been determined by X-ray crystallography. The crystals of I are triclinic: a = 9.1245(9) Å, b = 9.8572(6) Å, c = 11.0944(9) Å, α = 73.51(1)°, β = 79.917(6)°, γ = 72.161(7)°, Z = 2, space group $$P\bar 1$$ . In the centrosymmetric binuclear molecule of I, the copper atoms (Cu...Cu′, 2.621 Å) are linked through four bidentate chelating valerate ligands (av., Cu-O 1.969 Å). The coordination polyhedron of the Cu atom is a tetragonal pyramid with the nitrogen atom of the pyridine ring in the apical position at a longer distance (Cu-N, 2.190 Å). © Pleiades Publishing, Inc., 2006

A coordination compound of nickel(II) benzoate with nicotinamide [Ni(C 6H5COO)2(L)2(H2O) 2] (I) (L is nicotinic acid amide) is synthesized and studied by IR spectroscopy.

Inner-sphere hydrolysis of ethyl isothiocyanate in MoCl4{[N(Et)C(S)]2Cl}: Crystal structure of the product of hydrolysis, ethylammonium aquatetrachlorooxomolybdate(V) (NH3Et)[MoOCl4(H2O)]

The product of insertion MoCl4{[N(Et)C(S)]2Cl} (I) was obtained by reacting MoCl5 with EtNCS in dichloroethane. The hydrolysis of this complex gave single crystals of (NH3Et)[MoOCl4(H2O)] (II), which were characterized by X-ray crystallography. The crystals of II consist of complex anions [MoVOCl4(H2O)]- and ethylammonium cations united by an extended network of interionic contacts N-H⋯Cl, N-H⋯O, and C-H⋯O. The bond lengths in the coordination octahedron MoO2Cl4: Mo=O(oxo), 1.67 Å; Mo-O(H2O)trans, 2,381 Å, and Mo-Clcis, 2.365 Å. On the basis of the X-ray diffraction data, the assignment of the frequencies in the IR spectra of II was performed. The results of the X-ray diffraction study and IR spectroscopy for I allowed us to conclude that the addition of ethyl isothiocyanate to pentachloromolybdenum(V) is stereospecific
