INTRODUCTION AND OBJECTIVES The risk of stroke in atrial fibrillation is heterogeneous and depends upon underlying clinical conditions included in current risk stratification schemes. Recently, the CHA(2)DS(2)-VASc score has been included in guidelines to be more inclusive of common stroke risk factors seen in everyday clinical practice, and useful in defining "truly low risk" subjects. We aime...

BACKGROUND The CHA(2)DS(2)-VASc (Congestive heart failure, Hypertension, Age ≥75 years, Diabetes mellitus, previous Stroke/transient ischemic attack [TIA], Vascular disease, Age 65-74 years, and Sex category [female gender]) schema recently has been introduced to complement the CHADS(2) (Congestive heart failure, Hypertension, Age >75 years, Diabetes mellitus, and previous stroke or TIA) score ...

Antioxidant activities of four kinds of Japanese traditional fermented tea, Gishi-cha, Ishizuchi-kurocha, Awa-bancha, and Batabatacha, were compared. Antioxidant activity was evaluated by three parameters: copper ion reduction ability, radical trapping ability, and oxygen consumption rate. Processes of fermentation of these fermented teas are different. Goichi-cha and Ishizuchi-kurocha are prod...

Highly crystalline carbonated hydroxyapatite (CHA) nanorods with different carbonate contents were synthesized by a novel hydrothermal method. The crystallinity and chemical structure of synthesized nanorods were studied by Fourier transform infrared spectroscopy (FTIR), X-ray photo-electronic spectroscopy (XPS), X-ray diffraction (XRD), Raman spectroscopy, and transmission electron microscopy ...

Aims. In our ongoing search for close and faint companions around T Tauri stars in the Chamaeleon star-forming region, we here present observations of a new common proper motion companion to the young T-Tauri star and Chamaeleon member CT Cha and discuss its properties in comparison to other young, low-mass objects and to synthetic model spectra from different origins. Methods. Common proper mo...

The oxidation of NO to NO2 and the subsequent reduction by NH3 via a NO+ intermediate over proton-type chabazite zeolite (H-CHA) were investigated combination in situ infrared (IR) spectroscopy density functional theory (DFT) calculations. IR spectral results indicate that species formed under flow + O2 at 27–250 °C are more stable lower temperatures both H-CHA copper-cation-exchanged CHA (Cu-C...

The Chemical Hamiltonian Approach ~CHA! versions of the Roothaan and Kohn–Sham equations, labeled CHA/F and CHA/DFT, respectively, have been used to obtain the basis set superposition error ~BSSE!-corrected first-order electron density of the hydrogen fluoride dimer with several basis sets. We have analyzed the effect of BSSE in terms of the electronic relaxation, i.e., the redistribution of th...

Due to osteoconductivity of hydroxyapatite (HA), HA/polymer composite scaffolds have been investigated for bone tissue engineering by various groups. In scaffold fabrication, electrospinning of ultrafine fibrous scaffolds incorporated with substantial amounts of evenly distributed HA nanoparticles is still a challenge. The problem of nanoparticle agglomeration not only reduces the electrospinni...

Jack Goldstone argues that Comparative Historical Analysis (CHA) holds a distinct epistemological orientation vis-a-vis large-N , frequentist approaches that has proven to be particularly fertile for the study of revolutions. He begins by sketching this CHA epistemology, focusing on its use of Bayesian analysis, process tracing, and congruence testing. Goldstone then proceeds to show, via a his...
