Magnetic circular x-ray dichroism (MCXD) measurements at the Co ${L}_{2,3}$ and ${M}_{2,3}$ core edges reveal a strongly enhanced perpendicular orbital moment ( ${m}_{\mathrm{orb}}$) in Co/Pt multilayers which show magnetic anisotropy (PMA). MCXD signals Pt ${N}_{6,7}$ ${O}_{2,3}$ edges, arising from $5d\ensuremath{-}\mathrm{Co}3d$ hybridization, persist for thinnest layer. The hybridization is shown to be localized interface cause ${m}_{\mathrm{orb}}$ enhancement drives PMA. Unambiguous...
To understand the molecular mechanism of ligand-induced gating inositol 1,4,5-trisphosphate (IP3) receptor (IP3R)/Ca2+release channel, we analyzed channel properties deletion mutants retaining both IP3-binding and channel-forming domains IP3R1. Using intrinsically IP3R-deficient cells as host for expression, determined that six mutants, those lacking residues 1–223, 651–1130, 1267–2110, 1845–2042, 1845–2216, 2610–2748, did not exhibit any measurable Ca2+ release activity, whereas 1131–1379...
Three subtypes of inositol 1,4,5-trisphosphate receptor (IP3R1, IP3R2, and IP3R3) Ca2+ release channel share basic properties but differ in terms regulation. To what extent they contribute to complex signaling, such as oscillations, remains largely unknown. Here we show that HeLa cells express comparable amounts IP3R1 IP3R3, knockdown by RNA interference each subtype results dramatically distinct signaling patterns. Knockdown significantly decreases total signals terminates oscillations....
The spin, in-plane and out-of-plane orbital magnetic dipole moments of almost purely interfacial Co atoms were directly determined for Au/2-monolayer nanoclusters/Au(111) by angle-dependent circular x-ray dichroism (MCXD) measurements. field- temperature-dependent MCXD evidences a ferromagnetic(FM)-to-superparamagnetic phase transition in single-domain clusters with decreasing size. are remarkably enhanced as compared bulk values, verifying theoretical predictions. FM show strong...
Background: To assess the immunologic alteration and long-term prognosis after splenic injury from preservation treatment (PT) (embolization, splenorrhaphy, partial splencetomy) to compare with splenectomy (SN). Methods: The of patients blunt treated at seven tertiary emergency centers in Japan was retrospectively studied. Patients were followed up by telephone interview written questionnaire. Blood samples abdominal computer tomography scans taken who consented, indices remaining volume...
The first observation of a magnetic circular x-ray dichroism (MCXD) at the Mn L2,3 core edges in antiferromagnetic LaMnO3 shows canted spin and orbital ( m(orb)) moments arising from lattice distortions. An L2,3-edge MCXD ferromagnetic metals insulators, La1-xSr(x)MnO3+delta, reveals that m(orb) strongly depends on x metallic regime but remains unchanged with metal-to-insulator transition (x approximately 0.16). O K-edge MCXD, which caused by 2p-3d hybridization, is much larger metal than...
The ferromagnetic oxide ${\mathrm{La}}_{1\ensuremath{-}x}{\mathrm{Sr}}_{x}{\mathrm{CoO}}_{3}$ has been studied by magnetic circular x-ray dichroism (MCXD) in core-level absorption. In the Co ${2p}_{3/2,1/2}$ absorption, orbital and spin moments of $3d$ are deduced with use magneto-optical sum rules compared magnetization measurements. O $1s$ large negative MCXD structures observed, showing that $2p$ orbitals heavily mixed moment is parallel to total moment. relative magnitudes most...
The smokeless powders in 22 kinds of ammunitions seized from one the Japanese gang groups were analyzed by scanning electron microscopy/energy dispersive X-ray microanalysis (SEM/EDX). Copper(Cu), sulfur(S), potassium(K), silicon(Si), aluminum(Al), calcium(Ca), iron(Fe), chlorine(Cl), and barium(Ba) detected. Cu was found all samples. One sample contained a high amount Ba. part burnt powder to contain Cu, K, Ca, Fe S, other Fe, zinc(Zn). It has been reported that elements gunshot residues...
The purpose of the present study was to identify risk factors associated with a complicated hospital course in overdose patients admitted intensive care unit.A total 335 were retrospectively studied surgical and medical unit an academic tertiary hospital. Factors possibly evaluated. Complicated defined as occurrence pneumonia, rhabdomyolysis, decubitus ulcer, nerve palsy, prolonged intubation, hospitalization, or death.Of patients, 93 (27.8%) had course. found be high number ingested pills...
Serious arrhythmic events in most of patients suffering from sudden cardiac arrest are Ventricular Fibrillation (VF) and Tachycardia (VT). For these serious events, the timely employment an electrical defibrillator may lead to successful results. From this viewpoint, widespread deployment Automated External Defibrillators (AEDs) has been suggested important component AEDs is accurate quick detection by means appropriate algorithm. However ventricular arrhythmia not easy. In paper, we analyze...
A previously developed method for determining elastic constants of single crystals from polycrystalline specimens was applied to cubic and tetragonal zirconia. The is based on the orientation dependence lattice strain a stressed specimen as measured by X-ray diffraction also Kröner's equation relating polycrystals those crystal. simple loading device disc-shaped using Ti–Ni shape memory alloy. resulting constants, C11, C12, C44 zirconia were in fair agreement with directly same after...
Dynamic compression modulation attenuated total reflection Fourier transform infrared (ATR FT-IR) spectroscopic methods have been developed in this paper for characterizing polymer films. To obtain dynamic polarized ATR spectra, internal element (IRE) secure assemblies made of tungsten carbide with very high hardness (Knoop >1000 kgf/mm 2 ) designed. These are mounted on the Harrick Seagull® attachment and measured by step-scan FT-IR spectroscopy. The effect static compression, air gaps,...
We have studied the microscopic magnetic state of a double perovskite Sr2FeMoO6 by x-ray circular dichroism (XMCD). An Fe L3,2-edge XMCD reveals that formal Fe3+ ions an appreciable orbital moment (morb) parallel to their large spin (mspin), showing charge-transfer-induced, minority-spin (↓) t2g electrons. A weak but undoubted O K-edge was successfully detected, 2p-hole morb induced 2p-3d hybridization. Along with information obtained from observed Mo M3,2-edge XMCD, our findings verify...
