Abstract

We study a coupling flow of pure QCD gauge system by using the Monte Carlo Renormalization Group method. A rough location of the renormalized trajectory in two coupling space is obtained. Also we compare 4 different actions; (a)standard Wilson, (b)Symanzik's, (c)Iwasaki's and (d)QCDTARO's. The rotational symmetry is restored better as an action gets close to the renormalized trajectory., Comment: 4 pages of A4 format plus 1 Postscript figure, (tar+gzip+uuencode) Talk presented at LATTICE96(poster)

Abstract

The scaling behavior of pure gauge SU(3) in the region $\beta=5.85 - 7.60$ is examined by a Monte Carlo Renormalization Group analysis. The coupling shifts induced by factor 2 blocking are measured both on 32$^4$ and 16$^4$ lattices with high statistics. A systematic deviation from naive 2-loop scaling is clearly seen. The mean field and effective coupling constant schemes explain part, but not all of the deviation. It can be accounted for by a suitable change of coupling constant, including a correction term ${\cal O}(g^7)$ in the 2-loop lattice $\beta$-function. Based on this improvement, $\sqrt{\sigma}/\Lambda_{\overline {MS}}^{n_f=0}$ is estimated to be $2.2(\pm 0.1)$ from the analysis of the string tension $\sigma$., Comment: 4 pages of A4 format including 7-postscript figures

Abstract

We measure the sweep-to-sweep autocorrelations of blocked loops below and above the deconfinement transition for SU(3) on a $16^4$ lattice using 20000-140000 Monte-Carlo updating sweeps. A divergence of the autocorrelation time toward the critical $\beta$ is seen at high blocking levels. The peak is near $\beta$ = 6.33 where we observe 440 $\pm$ 210 for the autocorrelation time of $1\times 1$ Wilson loop on $2^4$ blocked lattice. The mixing of 7 Brown-Woch overrelaxation steps followed by one pseudo-heat-bath step appears optimal to reduce the autocorrelation time below the critical $\beta$. Above the critical $\beta$, however, no clear difference between these two algorithms can be seen and the system decorrelates rather fast., Comment: 4 pages of A4 format including 6-figures

Abstract

Background/purpose Photograph-based visual scoring has been used for evaluation of facial morphological changes. Here, we describe a three-dimensional computed tomography (3D- CT) method for objective analysis of facial and intra-facial (subcutaneous) changes. The effects of facial massage were examined using both methods. Methods Subjects were 12 healthy female volunteers without facial scars or deformation (age 30-54 years, mean 39.4 years). Photograph-based scoring of massage-induced morphological changes was done at the nasolabial folds, upper, lower and lateral cheeks and lower eyelids. For 3D- CT evaluation, the virtual center axis ( VCA) was set as the cranio-caudal longitudinal line, and the VCA-skin surface distances ( VSDs) were measured. Massage-induced changes of VSD were calculated (facial massage-induced change rate, FMCR). Intra-facial (subcutaneous) changes were also evaluated. Results Photograph-based scoring revealed marked morphological changes of the nasolabial folds after facial massage, and changes of the lower, upper and lateral cheeks and lower eyelid were also observed in more than half of the subjects. FMCR values were significantly changed in the paranasal area, nasolabial fold area and cranial part of the mandibular area. Photograph-based scores at the lower cheek and lower eyelid were well correlated with FMCR in the inferior part of the nasolabial fold and the mandibular area, respectively. Massage-induced changes of subcutaneous fat tissues and facial expression muscles were also apparent on CT images. Conclusion 3D- CT imaging is useful for objective evaluation of the effects of facial massage, including anatomical changes in subcutaneous structures. [ABSTRACT FROM AUTHOR]

27. Rep-rated e-beam-pumped KrF laser technology for inertial fusion energy drivers.

Author

Okuda, I., Takahashi, E., Matsushima, I., Matsumoto, Y., Kato, S., and Owadano, Y.

Abstract

Development of a high-repetition-rate (rep-rate) electron-beam (ebeam) pumped KrF laser is described. It aims at pulsed laser outputs of 20 J/80 ns at a rep rate of 1 Hz. Technical efforts are concentrated on diode-foil cooling, which is the key issue of the rep-rate e-beam amplifier technology. E-beam generation experiments have been started with the initial test results of several tens of consecutive shots at 1 Hz. Improvement in the energy-transfer efficiency in the rep-rate pulsed-power systems is also discussed. [ABSTRACT FROM PUBLISHER]

Abstract

Parathyroid glands arise from the third and fourth pharyngeal pouches. Parathyroid lesions sometimes develop ectopically. The aim of this article is to illustrate the knowledge of pharyngeal apparatus development to assist with diagnostic localization of ectopic parathyroid lesions. We retrospectively reviewed charts of 23 patients who received a diagnosis of ectopic parathyroid lesions. The ectopic lesions were widely distributed; cranially lesions were located on the carotid bifurcation, caudally in the right paraaortic region, ventrally on the surface of the sternohyoid muscle, and dorsally in the paraesophageal region. In most cases, parathyroid tissues were associated with structures related to the third or fourth pharyngeal pouches that traveled to regions where the ectopic lesions ultimately developed. In a few cases, lesions were not associated with these pouches and might have developed from parathyroid tissue that migrated due to an anomalous pathway of parathyroid travel. When patients present without entopic lesions, the presence of ectopic lesions should be evaluated based on an understanding of the developmental mechanisms of parathyroid glands and the frequency with which ectopic lesions have been found in specific locations. Systematic diagnosis can minimize the frequency with which ectopic lesions are missed during clinical care and maximize their accurate localization. [ABSTRACT FROM AUTHOR]
