The motivic Satake equivalence
No full textWe refine the geometric Satake equivalence due to Ginzburg, Beilinson–Drinfeld, and Mirković–Vilonen to an equivalence between mixed Tate motives on the double quotient L+G LG/ L+G and representations of Deligne’s modification of the Langlands dual group G^

Affine Grassmannians and geometric Satake equivalences
No full textI extend the ramified geometric Satake equivalence of Zhu [34] from tamely ramified groups to include the case of general connected reductive groups. As a prerequisite I prove basic results on the geometry of affine flag varieties
The geometric Satake correspondence for ramified groups
No full textWe prove the geometrical Satake isomorphism for a reductive group defined
over F=k((t)), and split over a tamely ramified extension. As an application,
we give a description of the nearby cycles on certain Shimura varieties via the
Rapoport-Zink-Pappas local models

Three-dimensional measurement with two cameras of a turbulent pipe flow by digital holographic-PTV
No full textThree-dimensional simultaneous measurements of velocity field in a turbulent pipe flow are performed by digital holographic velocimetry. We proposed holography technique with two laser beams. For this study, the Reynolds numbers was set to be 15000. The accuracy of the experimental method was confirmed by comparing the results from the method with DNS data by Satake et al. [4] when using the same Reynolds number. The velocity profiles obtained from the method was found to be in good agreement with that of the DNS data
Twisted geometric Satake equivalence
No full textWe generalize the classical Satake equivalence as follows. Let k be an
algebraically closed field, set O=k[[t]] and F=k((t)). For an almost simple
algebraic group G we classify central extensions of G(F) by the multiplicative
group. Any such extension E splits canonically over G(O). Consider the category
of G(O)-biinvariant perverse sheaves on E with a given Gm-monodromy . We show
that this is a tensor category, which is tensor equivalent to the category of
representations of a reductive group. We compute the root datum of this group.Comment: 22 pages, a reference to Lusztig is added. Final version to appear in

No full textKuga-Satake construction and cohomology of hyperkähler manifolds
No full textLet M be a simple hyperkähler manifold. Kuga-Satake construction gives an embedding of into the second cohomology of a torus, compatible with the Hodge structure. We construct a torus T and an embedding of the graded cohomology space for some l, which is compatible with the Hodge structures and the Poincaré pairing. Moreover, this embedding is compatible with an action of the Lie algebra generated by all Lefschetz -triples on M
Assessment of soluble cytotoxic T lymphocyte-associated antigen-4, transforming growth factor β1, and platelet-derived microparticles during dasatinib therapy for patients with chronic myelogenous leukemia
No full textShosaku Nomura, Tomoki Ito, Atsushi Satake, Kazuyoshi Ishii First Department of Internal Medicine, Kansai Medical University, Hirakata, Osaka, Japan Background: The outcome for chronic myelogenous leukemia (CML) patients presented in the chronic phase has changed dramatically since the introduction of tyrosine kinase inhibitor (TKI) therapy. Notably, an increased incidence of large granular lymphocytes (LGLs), which is related to immunological conditions, appears to be predictive of a favorable outcome for dasatinib therapy. We therefore examined the immunological characteristics of CML patients during dasatinib therapy by determining the plasma concentrations of five different biomarkers. Methods: The plasma levels of biomarkers, specifically interleukin-6, platelet-derived microparticles (PDMPs), soluble vascular cell adhesion molecule 1 (sVCAM-1), transforming growth factor (TGF) β1, and soluble cytotoxic T lymphocyte-associated antigen-4 (sCTLA-4), were measured by ELISA at baseline and after 2 and 6 months of TKI treatment. The incidence of LGLs was estimated by microscopic examination. Results: The levels of PDMPs, sVCAM-1, and TGFβ1 were significantly elevated in patients with CML. Dasatinib treatment was associated with a significant reduction in the levels of these markers and with an increased incidence of LGLs compared with imatinib or nilotinib treatment. In addition, an increased incidence of LGLs was significantly correlated with a decreased sCTLA-4 level during dasatinib therapy. Conclusion: The assessment of the levels of specific biomarkers may be beneficial to understand the immunological conditions of patients with CML during dasatinib treatment.
