Analysis method for PCBs in reclaimed oil using a fast-GC triple stage quadrupole mass spectrometer with the 13-component quantitation method

It is necessary for companies supplying reclaimed oil to analyze polychlorinated biphenyls (PCBs), because there is a possibility of the presence of contaminants due to trace-level PCBs in the reclaimed oil. However, common analysis methods of PCBs are time-consuming and complicated. Fast-GC triple stage quadrupole mass spectrometer with the 13-component quantitation method is an...

Is the 126 GeV Higgs boson mass calculable in gauge–Higgs unification?

We address the question of whether the recently observed Higgs mass $M_{H} = 126$GeV, of the order of the weak scale $M_{W}$, is calculable as a finite value in the scenario of gauge–Higgs unification. In the scenario formulated on a flat five-dimensional space-time, the Higgs mass is calculable, being protected under the quantum correction by gauge invariance, though the...

Clinical Characteristics and Outcomes of Patients with High Ankle-Brachial Index from the IMPACT-ABI Study

Background Reduced ankle–brachial index (ABI) is a predictor of cardiovascular events. However, the significance of high ABI remains poorly understood. This study aimed to assess the characteristics and outcomes of patients with high ABI. Methods The IMPACT-ABI study was a retrospective cohort study that enrolled and examined ABI in 3,131 patients hospitalized for cardiovascular...

Clinical Impact of Rapid Reduction of Low-Density Lipoprotein Cholesterol Level on Long-Term Outcome of Acute Myocardial Infarction in the Statin Era: Subanalysis of the ALPS-AMI Study

Background The optimal period to achieve target percent reduction of low-density lipoprotein cholesterol (LDL-C) level for secondary prevention of acute myocardial infarction (AMI) is not well established. Methods The Assessment of Lipophilic vs. Hydrophilic Statin Therapy in AMI (ALPS-AMI) study enrolled 508 patients (mean age, 66.0± 11.6 years; 80.6% male) who were hospitalized...

Kashima Takashi Miura Souichirou Ebisawa Takeshi Tomita Yusuke Miyashita Jun Koyama Uichi Ikeda The use of beta-blockers therapy has been recommended to reduce mortality in patients with left ventricular

Equivalence Classes of Boundary Conditions in SU(N) Gauge Theory on 2-Dimensional Orbifolds

Prediction of 1-year clinical outcomes using the SYNTAX score in patients with prior heart failure undergoing percutaneous coronary intervention: sub-analysis of the SHINANO registry

Although coronary artery disease (CAD) is common in patients with heart failure (HF), little is known about the prognostic significance of coronary lesion complexity in patients with prior HF undergoing percutaneous coronary intervention (PCI). The aim of this study was to investigate whether the coronary Synergy between Percutaneous Coronary Intervention with TAXus and Cardiac...

Z N twisted orbifold models with magnetic flux

We propose new backgrounds of extra dimensions to lead to four-dimensional chiral models with three generations of matter fermions, that is T 2 /Z N twisted orbifolds with magnetic fluxes. We consider gauge theory on six-dimensional space-time, which contains the T 2 /Z N orbifold with magnetic flux, Scherk-Schwarz phases and Wilson line phases. We classify all the possible...

Equivalence Classes of Boundary Conditions in Gauge Theory on Z3 Orbifold

We study equivalence classes of boundary conditions in a gauge theory on the orbifold T2/Z3. Orbifold conditions and those gauge transformation properties are given and the gauge equivalence is understood by the Hosotani mechanism. Mode expansions are carried out for six-dimensional Z3 singlet fields and a Z3 triplet field, and the one-loop effective potential for Wilson line...

Raman spectroscopic detection of the T-HgII-T base pair and the ionic characteristics of mercury

Developing applications for metal-mediated base pairs (metallo-base-pair) has recently become a high-priority area in nucleic acid research, and physicochemical analyses are important for designing and fine-tuning molecular devices using metallo-base-pairs. In this study, we characterized the HgII-mediated T-T (T-HgII-T) base pair by Raman spectroscopy, which revealed the unique...

Conversion to total cavopulmonary connection 9 years after closure of a large ventricular septal defect

We performed an extracardiac total cavopulmonary connection (TCPC) operation using tissue-engineered graft for a patient with elevated central venous pressure due to severe tricuspid valve insufficiency 9 years after closure of a large ventricular septal defect. Before the TCPC, this patient had a right atrial thrombus and pulmonary embolism for which thrombolytic therapy was...

WKB Approximations for Relativistic Particles

The Schwinger-DeWitt expansions are shown to give the WKB approximations for a free particle in the curved space-time. WKB approximations for a relativistic scalar particle in external electromagnetic fields are also given by using the same expansions in the Kaluza-Klein space. The higher order corrections are calculated concretely in this formulation.

Covariant Schrödinger Equation via Path Integrals

Propagation equations of infinitesimal time differences in path integral representations are investigated in a manifestly covariant way in the curved space-time. Covariant Schrödinger equations via these path integrals are studied by using a formula which expresses explicitly the relation between normal coordinates and general covariant ones within the required approximation. The...

Structural and physicochemical features on the metal-mediated base pairs

The chemical structure of the mercury-mediated T-T pair (T-HgII-T) was determined with 15N NMR spectroscopy. In order to determine the chemical structure of the T-HgII-T pair, 15N-15N J-coupling across a metal center (2JNN) was employed. Notably, this is the first observation of 2JNN in a biological macromolecule (DNA duplex). This pairing mode was found to be a irregular metal...

Relativistic Path Integrals

An elementary theory of relativistic path integrals is developed in the Lorentz-space. A path integral for a Dirac electron is formulated, in which the perturbation expansion is shown to give just the same rules as those given in the more usual formulation of field theory. A geometrical feature of path integrals is investigated by using Weyl's theory of phase connection and the...
