Properties of Scalar-Quark Systems in SU(3)c Lattice QCD

We perform the first study for the bound states of colored scalar particles $\phi$ ("scalar quarks") in terms of mass generation with quenched SU(3)$_c$ lattice QCD. We investigate the bound states of $\phi$, $\phi^\dagger\phi$ and $\phi\phi\phi$ ("scalar-quark hadrons"), as well as the bound states of $\phi$ and quarks $\psi$, i.e., $\phi^\dagger\psi$, $\psi\psi\phi$ and $\phi\phi\psi$ ("chimera hadrons"). All these new-type hadrons including $\phi$ have a large mass of several GeV due to large quantum corrections by gluons, even for zero bare scalar-quark mass $m_\phi=0$ at $a^{-1}\sim 1{\rm GeV}$. We find a similar $m_\psi$-dependence between $\phi^\dagger\psi$ and $\phi\phi\psi$, which indicates their similar structure due to the large mass of $\phi$. From this study, we conjecture that all colored particles generally acquire a large effective mass due to dressed gluons

Flexible network infrastructure for wearable computing using conductive fabric and its evaluation

金沢大学理工研究域電子情報学系Numbers of devices are distributed in the environment in wearable and ubiquitous computing systems, and all of such devices need power supply and communication ways as well as flexibility of placement. Both wireless and wired communication systems intrinsically contain the problems in power supply or flexibility of placement. In this paper, we introduce the flexible network infrastructure for wearable computing systems, named as TextileNet, and experimental results of its evaluation. TextileNet uses the wear both of sides of which are made of conductive fabric as electrodes. On this year, the power is supplied from a battery, and the devices are attached by sticking so that electric contact can obtain the sufficient power and communication way on the wear\u27s surface. This paper describes the implementation and evaluation of the TextileNet system. © 2006 IEEE

Direct measurement of hypoxia in a xenograft multiple myeloma model by optical-resolution photoacoustic microscopy

Using photoacoustic microscopy (PAM), we evaluated non-invasively oxygenation and vascularization in vivodue to multiple myeloma (MM) progression. Mice injected with MM.1S-GFP were monitored with a fluorescence microscope for tumor progression. In vivo PAM of the cerebral bone marrow quantified the total oxygen saturation (sO_2). At 28 days after the MM cell injection, the total sO_2 had decreased by half in the developing tumor regions, while in the non-tumor regions it had decreased by 20% compared with the value at one day post MM injection. The blood vessel density was reduced by 35% in the developing tumor regions, while in the non-tumor regions it was reduced by 8% compared with the value at one day post MM injection. Hence, PAM corroborated the development of hypoxia due to MM progression and demonstrated decreased vascularization surrounding the tumor areas

EGFR in enterocytes & endothelium and HIF1α in enterocytes are dispensable for massive small bowel resection induced angiogenesis

Background: Short bowel syndrome (SBS) results from significant loss of small intestinal length. In response to this loss, adaptation occurs, with Epidermal Growth Factor Receptor (EGFR) being a key driver. Besides enhanced enterocyte proliferation, we have revealed that adaptation is associated with angiogenesis. Further, we have found that small bowel resection (SBR) is associated with diminished oxygen delivery and elevated levels of hypoxia-inducible factor 1-alpha (HIF1α). Methods: We ablated EGFR in the epithelium and endothelium as well as HIF1α in the epithelium, ostensibly the most hypoxic element. Using these mice, we determined the effects of these genetic manipulations on intestinal blood flow after SBR using photoacoustic microscopy (PAM), intestinal adaptation and angiogenic responses. Then, given that endothelial cells require a stromal support cell for efficient vascularization, we ablated EGFR expression in intestinal subepithelial myofibroblasts (ISEMFs) to determine its effects on angiogenesis in a microfluidic model of human small intestine. Results: Despite immediate increased demand in oxygen extraction fraction measured by PAM in all mouse lines, were no differences in enterocyte and endothelial cell EGFR knockouts or enterocyte HIF1α knockouts by POD3. Submucosal capillary density was also unchanged by POD7 in all mouse lines. Additionally, EGFR silencing in ISEMFs did not impact vascular network development in a microfluidic device of human small intestine. Conclusions: Overall, despite the importance of EGFR in facilitating intestinal adaptation after SBR, it had no impact on angiogenesis in three cell types–enterocytes, endothelial cells, and ISEMFs. Epithelial ablation of HIF1α also had no impact on angiogenesis in the setting of SBS

In this book, an international team of fourteen scholars investigates the Chinese reception of Indian Buddhist ideas, especially in the sixth and seventh centuries. Topics include Buddhist logic and epistemology (pramāṇa, yinming); commentaries on Indian Buddhist texts; Chinese readings of systems as diverse as Madhyamaka, Yogācāra and tathāgatagarbha; the working out of Indian concepts and problematics in new Chinese works; and previously under-studied Chinese evidence for developments in India. The authors aim to consider the ways that these Chinese materials might furnish evidence of broader Buddhist trends, thereby problematizing a prevalent notion of “sinification”, which has led scholars to consider such materials predominantly in terms of trends ostensibly distinctive to China. The volume also tries to go beyond seeing sixth- and seventh-century China primarily as the age of the formation and establishment of the Chinese Buddhist “schools”. The authors attempt to view the ideas under study on their own terms, as valid Buddhist ideas engendered in a rich, “liminal” space of interchange between two large traditions.In this book, an international team of fourteen scholars investigates the Chinese reception of Indian Buddhist ideas, especially in the sixth and seventh centuries.
