Postmodification in Sakha (Yakut): Its atypical word-order and number agreement
( Fuyuki Ebata ) 한국알타이학회 2015 알타이학보 Vol.0 No.25
Altaic-type languages are characterized by the strong syntactic principle that the modifier always precedes the head. However in Sakha, one of Altaic-type languages, there are several postmodifiers that must follow the head noun against this principle. In addition, the postmodifier must agree in number with the preceding noun. This paper examines the semantic property of the postmodifiers and illustrates morphosyntactic structure of Sakha postmodification. No other Turkic languages show reverse word-order or agreement between the noun and the modifier. Although neighboring Tungusic languages have a similar structure called “agreement”, the similarity is merely superficial and Sakha postmodification does not show consistent similarity to either of two types of Tungusic “agreement”.
Bare nominal secondary predicates in Sakha (Yakut)
( Fuyuki Ebata ) 한국알타이학회 2013 알타이학보 Vol.0 No.23
In Sakha (Yakut), bare nominals can be employed to function as a secondary predicate. The secondary predicate forms a depictive construction, and it describes the temporal state of the subject in intransitive clauses or that of the object in transitive clauses. Though Sakha bare nominals do not function adverbially, secondary predicates do serve as an adverbial phrase in a secondary predicate construction. Semantic type of verbs plays a significant role in the clause structure with a secondary predicate. It is with a transportation, giving-and-receiving, movement, stative, or change-of-state verb that the bare nominal secondary predicate construction is allowed. Semantically the target of the secondary predicate must be a concrete nominal, and the secondary predicate itself takes on a non-gradual meaning. Syntactically the secondary predicate usually occupies the immediate preverbal position, but it can be in other positions unless it is situated before the target.
A contrastive study of WH-question suffixes in Sakha and Tyvan
Fuyuki EBATA,Arzhaana Syuryun 한국알타이학회 2022 알타이학보 Vol.- No.32
This study first describes the uses of the Sakha and Tyvan WH-question suffixes, and then provides a contrastive analysis of the WH-question suffixes of the two cognate languages. The Tyvan WH-question suffix has a wider range of usage than the equivalent Sakha suffix. The appearance of the Tyvan WH-question suffix in non-existential and presumptive sentences is particularly interesting because they contain no WH words. The function of the Tyvan WH-question suffix in non-existential and presumptive sentences should be explained by the concept of egophoricity. In non-existential sentences, the WH-question suffix describes the speaker’s mental status in the form of assertions and in questions the hearer’s mental status. In presumptive sentences, it expresses an inference based on the speaker’s feelings, memories, or observations. In conclusion, the occurrence of the Tyvan WH-question suffix is a pragmatically conditioned element rather than a grammatically required question marker.
Interpolated Regression for On-line Local Modeling in Feedforward Learning Control
Kenji Sugimoto,Fuyuki Ito 제어로봇시스템학회 2014 제어로봇시스템학회 국제학술대회 논문집 Vol.2014 No.10
This paper proposes a technique of on-line modeling for feedforward (FF) learning control. For an unknown nonlinear multi-input multi-output (MIMO) plant which is free of zero dynamics, we construct a bank of filters each of which corresponds to a local model of inverse dynamics. In real time we select one such filter corresponding to the current operating point (called scheduler) and accumulate input-output (i/o) data to the filter while we derive FF control signal via regression from the accumulated data. The number of filters is finite but the plant operates continuously, hence we need to discretize the scheduler for classification. In a conventional scheme, however, we have merely truncated the value and resulted in a large approximation error. This paper proposes yet another scheme that uses an interpolation technique for regression in local modeling, thereby improving accuracy of response shaping. Numerical simulation is carried out to verify effectiveness of the proposed scheme.

The National Institution for Academic Degrees and University Evaluation (NIAD-UE) is engaged in the awarding of academic degrees based on the accumulation of credits. These credits must be classified according to pre-determined criteria for the chosen disciplinary field by each applicant. This classification is checked by the subcommittees whose members are well-versed in the syllabus of each course. We have proposed the Course Classification Support system (CCS) and the Active Course Classification Support system (ACCS) that can support the course classification by constructing the term-classification databases such that myDB or myDBc. Furthermore, we have combined ACCS with the course examples that are assigned for every fields in NIAD-UE and are used to guide the course classification. However, the combination is not necessarily effective since they are used independently. In this paper, we introduce ACCS to a learning mechanism in order to combine the course examples and the term-classification databases effectively. We show an application example to show the effectiveness of our method.

Aberrant wound closure occurs in a broad range of wounds and scars, and the altered regulation of transcription factors in wound areas can account for both of those conditions. This study aimed to explore the function of the transcription factor Smad3 in wound healing using a tongue wound model in Smad3 knockout (Smad3–/–) mice and with Smad3 small interfering RNA (siRNA) transfected human gingival fibroblasts (HGFs). Smad3 –/–mice were used to examine the extent of repair in tongue wounds. Cell migration was evaluated in HGFs using wound healing assays. The mRNA expression levels of Sox2, E-cadherin, fibronectin, and vimentin were examined in HGFs using reverse transcription-quantitative polymerase chain reaction. Histopathological analysis of wound closure in Smad3–/– mice showed rapid re-epithelialization and remodeling in tongue wound repair compared with Smad3+/+ mice. Increased numbers of neutrophils were identified in the wounds of Smad3 –/– mice. Sox2 and phospho-E-cadherin expression levels were increased in Smad3–/– mice. Smad3 knockdown by siRNA increased cell migration of HGFs. In addition, Sox2, E-cadherin, fibronectin, and vimentin mRNA levels were significantly increased in Smad3 siRNA-transfected HGFs compared with controls. Collectively, these findings demonstrate that a Smad3 deficiency can expedite wound healing and increase immune reactions and extracellular matrix formation after tongue injuries, boosting recovery through Sox2 and E-cadherin. Consequently, Smad3 inhibition would help stimulate tongue wound healing.

Objective: Diagnosis of sporadic cerebellar ataxia is a challenge for neurologists. A wide range of potential causes exist, including chronic alcohol use, multiple system atrophy of cerebellar type (MSA-C), and sporadic late cortical cerebellar atrophy. Recently, an autosomal-dominant spinocerebellar ataxia (SCA) mutation was identified in a cohort of patients with non-MSA-C sporadic cerebellar ataxia. The aim of this study is to genetically screen genes involved in SCA in a Japanese single-hospital cohort. Methods: Over an 8-year period, 140 patients with cerebellar ataxia were observed. There were 109 patients with sporadic cerebellar ataxia (no family history for at least four generations, 73 patients with MSA-C, and 36 patients with non-MSA-C sporadic cerebellar ataxia) and 31 patients with familial cerebellar ataxia. We performed gene analysis comprising SCA1, 2, 3, 6, 7, 8, 12, 17, 31, and dentatorubro-pallidoluysian atrophy (DRPLA) in 28 of 31 non-MSA-C sporadic patients who requested the test. Familial patients served as a control. Results: Gene abnormalities were found in 57% of non-MSA-C sporadic cerebellar ataxia cases. Among patients with sporadic cerebellar ataxia, abnormalities in SCA6 were the most common (36%), followed by abnormalities in SCA1 (7.1%), SCA2 (3.6%), SCA3 (3.6%), SCA8 (3.6%), and DRPLA (3.6%). In contrast, gene abnormalities were found in 75% of familial cerebellar ataxia cases, with abnormalities in SCA6 being the most common (29%). For sporadic versus familial cases for those with SCA6 abnormalities, the age of onset was older (69 years vs. 59 years, respectively), and CAG repeat length was shorter (23 vs. 25, respectively) in the former than in the latter (not statistically significant). Conclusion: Autosomal-dominant mutations in SCA genes, particularly in SCA6, are not rare in sporadic cerebellar ataxia. The reason for the frequency of mutations in SCA6 remains unclear; however, the reason may reflect a higher age at onset and variable penetrance of SCA6 mutations.
