Multiple Movement AND D-LINKING
Morita, Hisashi 대한언어학회 2003 언어학 Vol.11 No.2
This paper aims to resolve problems with multiple movements of wh-phrases, particularly, in Bulgarian. The topic includes discussions of (ⅰ) why and how multiple movements are possible, (ⅱ) what kind of movement they are, that is, whether they are WH movement as Pesetsky (2000) argues or focus movement as Bo??kovi?? (1998) claims, and (ⅲ) why D-linked wh-Phrases can remain in situ. I will argue that multiple movement of wh-phrases is not WH but focus movement and will show that D-linked wh-phrases can omit their WH features due to Pragmatic support and, because of this, they can escape overt movement.
Imaging features of Stafne bone defects on computed tomography: An assessment of 40 cases
Morita, Lucas,Munhoz, Luciana,Nagai, Aline Yukari,Hisatomi, Miki,Asaumi, Junichi,Arita, Emiko Saito Korean Academy of Oral and Maxillofacial Radiology 2021 Imaging Science in Dentistry Vol.51 No.1
Purpose: This study was performed to assess and describe the imaging features of 40 cases of Stafne bone defects (SBDs) on computed tomographic (CT) examinations. Materials and Methods: This study collected data, including age and sex, from 40 patients with SBDs who underwent CT exams. The imaging features of the SBDs were assessed in terms of their location, average size, the relationship of their contour with the cortical plate of the lingual mandible, bone margins, degree of internal density, shape, topographic relationship between the defect and the mandibular edge, the distance from the SBD to the base of the mandible, and the Ariji classification (type I, II, and III). Results: The average age was 57.3 years(range, 28-78 years), and the patients were predominantly male (70%). In all cases (100%), the posterior unilateral lingual SBD variant was observed. Within the Ariji classification, type I was the most common (60%). Among the most frequently observed radiographic characteristics were thick sclerotic bone margin across the entire defect contour, completely hypointense internal content, an oval shape, and continuity with the mandibular base with discontinuity of the mandibular edge. Conclusion: This study showed that posterior SBDs could present with an oval or rounded shape, complete hypodensity, and thick sclerotic margins. Likewise, SBDs could appear almost anywhere, with minor differences from the classic SBD appearance. It is fundamental for dental practitioners to know the imaging features of SBDs, since they are diagnosed primarily based on imaging.
A distinct functional distribution of α and γ motoneurons in the rat trigeminal motor nucleus
Morita-Isogai, Yukako,Sato, Hajime,Saito, Mitsuru,Kuramoto, Eriko,Yin, Dong Xu,Kaneko, Takeshi,Yamashiro, Takashi,Takada, Kenji,Oh, Seog Bae,Toyoda, Hiroki,Kang, Youngnam Springer-Verlag 2017 BRAIN STRUCTURE AND FUNCTION Vol.222 No.7
<P>Gamma-motoneurons (gamma MNs) play a crucial role in regulating isometric muscle contraction. The slow jaw-closing during mastication is one of the most functional isometric contractions, which is developed by the rank-order recruitment of alpha-motoneurons (alpha MNs) in a manner that reflects the size distribution of alpha MNs. In a mouse spinal motor nucleus, there are two populations of small and large MNs; the former was identified as a population of gamma MNs based on the positive expression of the transcription factor estrogen-related receptor 3 (Err3) and negative expression of the neuronal DNA-binding protein NeuN, and the latter as that of alpha MNs based on the opposite pattern of immunoreactivity. However, the differential identification of alpha MNs and gamma MNs in the trigeminal motor nucleus (TMN) remains an assumption based on the size of cell bodies that were retrogradely stained with HRP. We here examined the size distributions of alpha MNs and gamma MNs in the dorsolateral TMN (dl-TMN) by performing immunohistochemistry using anti-Err3 and anti-NeuN antibodies. The dl-TMN was identified by immunopositivity for vesicular glutamate transporter-1. Immunostaining for choline acetyltransferase and Err3/NeuN revealed that the dl-TMN is composed of 65% alpha MNs and 35% gamma MNs. The size distribution of alpha MNs was bimodal, while that of gamma MNs was almost the same as that of the population of small alpha MNs , suggesting the presence of alpha MNs as small as gamma MNs. Consistent with the size concept of motor units, the presence of smaller jaw-closing alpha MNs was coherent with the inclusion of jaw-closing muscle fibers with smaller diameters compared to limb muscle fibers.</P>
Polymeric Gel Electrolytes for Electric Double Layer Capacitors
Morita, Masayuki,Qiao, Jin-Li The Korean Electrochemical Society 2003 한국전기화학회지 Vol.6 No.2
Proton conducting polymeric gels as the electrolytes of electrochemical capacitors have been prepared by two different methods: 1) swelling a polymethacrylate-based polymer matrix in aqueous solutions of inorganic and organic acids, and 2) polymerizing complexes of anhydrous acids and prepolymers with organic plasticizer. The FT-IR spectra strongly suggest that the carbonyl groups in the polymer matrix interact with protons from the doped acids. High ionic (proton) conductivity in the range of $6\times10^{-4}-4\times10^{-2}\;S\;cm^{-1}$ was obtained at room temperature for the aqueous gels. The non-aqueous polymer complexes showed rather low ionic conductivity, but it was about $10^{-3}\;S\;cm^{-1}\;at\;70^{\circ}C$ for the $H_3PO_4$ doped polymer electrolyte. The mechanisms of ion (proton) conduction in the polymeric systems are discussed.
