Affect-Loaded Questions in Japanese Storytelling: An Analysis of Grammar, Prosody, and Body Movements of Story Recipients’ Questions  [PDF]
Chisato Koike
Open Journal of Modern Linguistics (OJML) , 2015, DOI: 10.4236/ojml.2015.55043
Abstract: The present study explores affective stance in conversational storytelling by investigating the ways in which unknowing story recipients display affective stances toward a teller’s story through questions that deploy multimodal resources. The data are based on videotaped natural face-to-face conversations between native Japanese speakers. While unknowing story recipients ask questions of the storyteller only to elicit factual information (“neutral questions”), they also ask questions layered with affect (“affect-loaded questions”). Building on studies on affect and stance, assessment, questions, and alignment and affiliation in storytelling, I demonstrate how unknowing story recipients ask affect-loaded questions to elicit and display affective stances toward story contents by exploiting linguistic and non-linguistic resources. First, I explicate how unknowing story recipients employ not only linguistic devices (e.g., emotion words, wh-questions, and deictic expressions such as sonna “like that”), but also prosody, facial expressions, body movements, and pre-/concurrent-laughter in order to load questions with affective stance that display, for example, disgust, humor, sarcasm, criticism, or surprise. Secondly, I show how unknowing story recipients use rhetorical questions to express their affect (rather than to elicit information from the storyteller). Thirdly, I demonstrate how affiliation of affective stance between storyteller and unknowing story recipients influences the trajectory of storytelling and how the participants negotiate their affective stances. This study sheds light on the interactional process of how participants in talk-in-interaction display affective stance through a range of multimodal resources, by examining how unknowing story recipients ask affect-loaded questions of the storyteller. It illuminates the social practice of story recipients’ active participation in storytelling activity that is embedded in social interaction, through their use of questions that dynamically co-construct and negotiate affective stance.
Expression of CD133 and Extracellular Matrix Molecules in Malignant Brain Tumors  [PDF]
Seiichi Yoshida, Toshiro Koike
Neuroscience & Medicine (NM) , 2011, DOI: 10.4236/nm.2011.24052
Abstract: Background: CD133 could be characterized as a “stem-like” cell subpopulation and an invasive tumor phenotype. The objectives of this study were to investigate the relationship of CD133 and other remodeling factors such as matrix metalloproteinases (MMP) in the brain tumors. Methods: Tumors from 13 patients with brain tumors (8 lung cancer metastasis, 3 breast cancer metastasis, 2 gliomas) were studied to investigate the expression-patterns of CD133, EGFR, MT1-MMP, and MMP7 using the immunostaining and RT-PCR analysis. Results: EGFR immunostaining was detected in 75% (6/8) and 67% (1/3) of brain metastasis from lung adenocarcinoma and breast cancer, respectively. MT1-MMP immunostaining was also detected in 73% (8/11) of these brain metastasis. CD133 was not detected in these 13 patients. EGFR immunostaining was detected in 75% (6/8) and 67% (1/3) of brain metastasis from lung adenocarcinoma and breast cancer, respectively. MT1-MMP immunostaining was also detected in 73% (8/11) of these brain metastasis. CD133 was not detected in these 13 patients. Conclusions: The expression of CD133 indicates a marker for brain tumor initiating.
Influence of Fine Zirconia Particle Shot Peening on Sliding Wear of Zirconia-Silicon Carbide Composites  [PDF]
Hitonobu Koike, Koji Takahashi
Journal of Surface Engineered Materials and Advanced Technology (JSEMAT) , 2017, DOI: 10.4236/jsemat.2017.72004
Abstract: In this paper, the sliding contact fatigue wear performance of shot-peened zirconia-silicon carbide composite (ZrO2/SiC) plates in contact with silicon nitride balls under compressive residual stress in dry conditions was investigated in order to improve the wear resistance of ZrO2/SiC friction parts. The wear resistance of ZrO2/SiC plates after shot peening was higher than that of plates not treated with shot peening in sliding wear testing under Hertziancontact. Due to fine Zirconia particle shot peening, the tetragonal phase crystal structure in ZrO2 in the near-surface of ZrO2/SiC plates was changed, and 1100 MPa compressive residual stress could be introduced into the near-surface layer of ZrO2/SiC plates. The compressive residual stress was determined to be the main factor in the improvement of the sliding wear resistance of ZrO2/SiC plates.
The new era of autoimmune disease research

Abstract: Microarray analysis and gene expression profiling allow patterns of gene expression in diseases and developmental processes to be assessed. Advances in biological databases have enabled the large-scale expression profiling data to be processed and the foundation for biological interpretation to be laid. Despite this, a major limitation involves the interpretation of massive amounts of microarray data. In microarray analysis, which is often used to identify differentially expressed genes, genes that are expressed at higher or lower levels than controls are of interest. In the previous issue of Arthritis Research & Therapy, Lee and colleagues [1] conducted gene expression and bioinformatics analyses between healthy individuals and patients with systemic lupus erythematosus (SLE) and provided insights into biological and functional abnormalities in SLE as well as abnormal regulatory networks. Such analyses - that is, gene ontology analysis, which is used to classify genes into functionally related gene groups, and network pathway analysis, which identifies relationships among these genes - provide an additional layer of insight that cannot be achieved by focusing on individual molecules [1].Lee and colleagues [2] previously demonstrated, by DNA microarray and bioinformatics analyses, that genes related to the immune response were differentially expressed in patients with SLE compared with healthy controls. Other studies have also reported increased expression of IFN-inducible genes (that is, the 'IFN signature') in peripheral blood cells from patients with SLE [2-4]. Many groups are currently looking into pathological roles of plasmacytoid dendritic cells (pDCs) and IFN-inducible genes in SLE since pDCs are major producers of IFN-α [4-7]. Given that SLE is a systemic disease that influences multiple organs, Lee and colleagues [1] emphasized the importance of assessing biological and cellular abnormalities associated with SLE other than those related to the immune respo
Examples of a complex hyperpolar action without singular orbit

Cubo (Temuco) , 2010, DOI: 10.4067/S0719-06462010000200009
Abstract: the notion of a complex hyperpolar action on a symmetric space of non-compact type has recently been introduced as a counterpart to the hyperpolar action on a symmetric space of compact type. as examples of a complex hyperpolar action, we have hermann type actions, which admit a totally geodesic singular orbit (or a fixed point) except for one example. all principal orbits of hermann type actions are curvature-adapted and proper complex equifocal. in this paper, we give some examples of a complex hyperpolar action without singular orbit as solvable group free actions and find complex hyperpolar actions all of whose orbits are non-curvature-adapted or non-proper complex equifocal among the examples. also, we show that some of the examples possess the only minimal orbit.

Valores funcionales de las locuciones prepositivas en espa ol
Kazumi Koike
Onomázein : Revista de Lingüística, Filología y Traducción , 1997,
Abstract: Frente al carácter cerrado del inventario de las preposiciones espa olas, las locucines prepositivas tienen un carácter abierto. Las locuciones prepositivas del tipo "Prep. + Núcleo + Prep.", analizadas en este trabajo, no presentan uniformidad funcional y desempe an diversas funciones sintácticas. El autor establece dos grupos de locuciones prepositivas: las gramaticalizadas, cuyo núcleo ha perdido su significado original, y otras, que son productivas sólo en determinadas estructuras. (Contrary to the closed nature of the inventory of Spanish prepositions, prepositional idioms are a open category. Prepositional idioms of the type "Prep. + Core + Prep.", analyzed in this paper, do not show a functional uniformity and play different syntactic functions. The author points to two groups of prepositional idioms: grammaticalized prepositional idioms, whose core has lost its original meaning, and others, which are productive in determined structures.)
Examples of a complex hyperpolar action without singular orbit

Abstract: The notion of a complex hyperpolar action on a symmetric space of non-compact type has recently been introduced as a counterpart to the hyperpolar action on a symmetric space of compact type. As examples of a complex hyperpolar action, we have Hermann type actions, which admit a totally geodesic singular orbit (or a fixed point) except for one example. All principal orbits of Hermann type actions are curvature-adapted and proper complex equifocal. In this paper, we give some examples of a complex hyperpolar action without singular orbit as solvable group free actions and find complex hyperpolar actions all of whose orbits are non-curvature-adapted or non-proper complex equifocal among the examples. Also, we show that some of the examples possess the only minimal orbit. La noción de una acción hiperpolar compleja sobre un espacio simétrico de tipo no compacto fue recientemente introducida como el análogo de la acción hiperpolar sobre un espacio simétrico de tipo compacto. Como ejemplos de una acción hiperpolar complejas, nosotros tenemos acciones de tipo Hermann, las cuales admiten una orbita (o un punto fijo) singular totalmente geodesica excepto para un ejemplo. Todas las orbitas principales de acciones de tipo Hermann son curvatura-adaptadas y unifocales complejas propias. este artículo, nosotros damos algunos ejemplos de una acción hiperpolar compleja sin orbitas singulares como grupo soluble de acciones libres y encontramos acciones complejas hiperpolares cuyas orbitas son no curvatura-adaptadas o no propias unifocales complejas. También, mostramos que algunos de los ejemplos poseen solamente orbitas minimales.
Hadron Structures and Perturbative QCD
Yuji Koike
Physics , 1999,
Abstract: In the first part of this talk, I will summarize recent developments in the study of the chiral-odd spin-dependent parton distributions h_1(x,Q^2) and h_L(x,Q^2) of the nucleon, in particular, (i) Next-to- leading order Q^2 evolution of h_1(x,Q^2) and (ii) Leading order Q^2 evolution of the twist-3 distribution $h_L(x,Q^2)$ and the universal simplification of the Q^2 evolution of all the twist-3 distributions in the large $N_c$ limit. The second part of this talk will be devoted to a systematic analysis on the light-cone distribution amplitudes of vector mesons ($\rho$, $\omega$, $\phi$, $K^*$ etc) relevant for exclusive processes producing these mesons. In particular, twist-3 distribution amplitudes are discussed in detail.
rho, omega, phi-Nucleon Scattering Lengths from QCD Sum Rules
Y. Koike
Physics , 1993, DOI: 10.1103/PhysRevC.51.1488
Abstract: The QCD sum rule method is applied to derive a formula for the rho, omega, phi meson-nucleon spin-isospin-averaged scattering lengths $a_{\rho,\omega,\phi}$. We found that the crucial matrix elements are $\langle\bar{q}\gamma_\mu D_\nu q\rangle_N$ ($q=u,d$) (twist-2 nucleon matrix element) for $a_{\rho,\omega}$ and $m_s\langle\bar{s}s\rangle_N$ for $a_\phi$, and obtained $a_\rho =0.14\pm 0.07$ fm, $a_\omega =0.11\pm 0.06$ fm and $a_\phi =0.035\pm 0.020$ fm. These small numbers originate from a common factor $1/(m_N+m_{\rho,\omega,\phi})$. Our result suggests a slight increase ($< 60$ MeV for $\rho$, $\omega$, and $<15$ MeV for $\phi$) of the effective mass of these vector mesons in the nuclear matter (in the {\it dilute} nucleon gas approximation). The origin of the discrepancy with the previous study was clarified.
