Variation analysis of free-style hand-written character pattern in documents
Yoshimasa Kimura,Kazumi Odaka 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8
We investigated variation analysis of individual character pattern written in free style and introduce ouranalysis strategy that combines five characteristics guessed to influence character variation and four types of analysis methods. The position of character, the order of writing the character, the writing time, writing pressure, etc. were selected as the five characteristics and the four analysis methods are constituted from an analysis of individualcharacteristics, relations between each characteristic, etc. Results of the analysis for collected characters show the writing time strongly influences the variation of character pattern.

<P><I>Acetabularia</I> rhodopsins are the firstmicrobialrhodopsins discovered in a marine plant organism, <I>Acetabulariaacetabulum</I>. Previously, we expressed <I>Acetabularia</I> rhodopsin II (ARII) by a cell-free system from one of two opsingenes in <I>A. acetabulum</I> cDNA and showed that ARIIis a light-driven proton pump [Wada, T., et al. (2011) <I>J.Mol. Biol.</I><I>411</I>, 986–998]. In thisstudy, the photochemistry of ARII was examined using the flash-photolysistechnique, and data were analyzed using a sequential irreversiblemodel. Five photochemically defined intermediates (P<SUB><I>i</I></SUB>) were sufficient to simulate the data. Noticeably, both P<SUB>3</SUB> and P<SUB>4</SUB> contain an equilibrium mixture of M, N,and O. Using a transparent indium tin oxide electrode, the photoinducedproton transfer was measured over a wide pH range. Analysis of thepH-dependent proton transfer allowed estimation of the p<I>K</I><SUB>a</SUB> values of some amino acid residues. The estimated valueswere 2.6, 5.9 (or 6.3), 8.4, 9.3, 10.5, and 11.3. These values wereassigned as the p<I>K</I><SUB>a</SUB> of Asp81 (Asp85<SUP>BR</SUP>) in the dark, Asp92 (Asp96<SUP>BR</SUP>) at N, Glu199 (Glu204<SUP>BR</SUP>) at M, Glu199 in the dark, an undetermined proton-releasingresidue at the release, and the pH to start denaturation, respectively.Following this analysis, the proton transfer of ARII is discussed.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/bichaw/2011/bichaw.2011.50.issue-41/bi2009932/production/images/medium/bi-2011-009932_0006.gif'></P>

Background and Purpose Differences in measurement of the extent of acute ischemic stroke using the Alberta Stroke Program Early Computed Tomographic Score (ASPECTS) by non-contrast computed tomography (CT-ASPECTS stratum) and diffusion-weighted imaging (DWI-ASPECTS stratum) may impact the efficacy of endovascular therapy (EVT) in patients with a large ischemic core. Methods The RESCUE-Japan LIMIT (Recovery by Endovascular Salvage for Cerebral Ultra-acute Embolism Japan–Large IscheMIc core Trial) was a multicenter, open-label, randomized clinical trial that evaluated the efficacy and safety of EVT in patients with ASPECTS of 3–5. CT-ASPECTS was prioritized when both CT-ASPECTS and DWI-ASPECTS were measured. The effects of EVT on the modified Rankin Scale (mRS) score at 90 days were assessed separately for each stratum. Results Among 183 patients, 112 (EVT group, 53; No-EVT group, 59) were in the CT-ASPECTS stratum and 71 (EVT group, 40; No-EVT group, 31) in the DWI-ASPECTS stratum. The common odds ratio (OR) (95% confidence interval) of the EVT group for one scale shift of the mRS score toward 0 was 1.29 (0.65–2.54) compared to the No-EVT group in CT-ASPECTS stratum, and 6.15 (2.46–16.3) in DWI-ASPECTS stratum with significant interaction between treatment assignment and mode of imaging study (<i>P</i>=0.002). There were significant interactions in the improvement of the National Institutes of Health Stroke Scale score at 48 hours (CT-ASPECTS stratum: OR, 1.95; DWIASPECTS stratum: OR, 14.5; interaction <i>P</i>=0.035) and mortality at 90 days (CT-ASPECTS stratum: OR, 2.07; DWI-ASPECTS stratum: OR, 0.23; interaction <i>P</i>=0.008). Conclusion Patients with ASPECTS of 3–5 on MRI benefitted more from EVT than those with ASPECTS of 3–5 on CT.
