Case Alternations in Potential Constructions in Japanese and their Semantic Implications
( Hiroaki Nakamura ),( Takeshi Fujita ) 한국언어정보학회 1998 국제 워크샵 Vol.1998 No.-
In potential constructions in Japanese any argument of a base verb, whether it is an argument, an adjunct or even an argument with no thematic relation to the verb, can be marked with nominative case. Addressing the problem of various types of case alternations as well as ``ga-no`` conversion, this paper argues for the existence of some semantically motivated mechanism licensing nominative and genitive case, which adequately accounts for the distributions of these cases in these constructions. We also claim that there is a close connection between the morphological realization of case and the overall semantic interpretation of a sentence.
Predictive Control and Estimation for Systems with Information Structured Constraints
Toru Namerikawa,Takeshi Hatanaka,Masayuki Fujita 제어로봇시스템학회 2011 제어로봇시스템학회 국제학술대회 논문집 Vol.2011 No.10
This paper deals with a predictive control and estimation problem with information structured constraints in a constrained finite-time optimal control framework. A large-scale system with information structures is defined as a system in which each subsystem collects spatio-temporally different information, and in general it is necessary to collect and process information in a distributed fashion. We propose a novel predictive control scheme and an estimation law with local information that each distributed subsystem obtains. The effectiveness of the proposed control and estimation law is evaluated through numerical simulations of a simplified micro grid.

We report an extremely rare case of primary squamous cell carcinoma of the stomach. A 69-year-old man was admitted to our hospital with a 2-month history of dysphagia and tarry stools. Endoscopic examination revealed a cauliflower-shaped protruding mass along the lesser curvature of the gastric cardia. Biopsy of the lesion revealed squamous cell carcinoma of the stomach. Computed tomography revealed a thickened stomach wall and a mass protruding into the gastric lumen. Total gastrectomy with splenectomy, distal pancreatectomy, and Roux-en-Y reconstruction was performed, together with a lower thoracic esophagectomy via a left thoracotomy. Histopathological examination of the specimen revealed well-differentiated squamous cell carcinoma of the stomach. Postoperative follow-up was uneventful for the first 18 months. However, multiple liver metastases and para-aortic lymph node metastasis developed subsequently. Despite systemic combination chemotherapy, the patient died because of progression of the recurrent tumors. Here, we review the characteristics of 56 cases of gastric squamous cell carcinoma reported in Japan.

Organic thin-film diodes with internal charge separation zone

We demonstrate the fabrication of new organic thin-lm diodes with an internal bipolar charge separation (ICS) zone. Wefabricated an organic double-layer diode with the structure of indium-tin oxide (ITO)/tris(8-quinolinolato)aluminum(III) (Alq3)/N,N0-bis(3-methylphenyl)-1,10-biphenyl-4,40-diamine (TPD)/Al. The stacking order of Alq3 and TPD of this diode is reversedcompared with conventional organic double-layer LEDs. In the ITO/Alq3/TPD/Al device, only a small current ows in both caseswhen the ITO electrode is biased positive or negative, because the device has large charge injection barriers and transport resistance.When the combined zone composed of Mg-doped Alq3 and vanadium oxide layers was inserted between the Alq3/TPD interface,large current ow was observed at the positive bias on ITO electrode. The diode behaved quite similar with the conventional organicLED, ITO/TPD/Alq3/Al. The large increase of forward current can never be ascribed to the decrease of injection barriers nor chargetransport resistance, because no change of device conguration was added except for the addition of the zone at the Alq3/TPDinterface. This large forward current ow was ascribed to the internal bipolar charge separation within the added zone..

In this research, we propose an energy-efficient predictive control system with outside-air-introduced-type air conditioner in large-scale data center. The system consists of two parts; a predictive part and a control part. We propose to use a dynamic model construction technique called just-in-time (JIT) modeling in the predictive part. It can estimate the air temperature and humidity in the DC room and temperature at the inlet of servers at a high accuracy while the update of data center model is constructed naturally. We also propose to use a control algorithm that utilizes air enthalpy at outside and DC room in addition to the air temperature and humidity in the control part. Owing to the enthalpy, we achieve an effective energy-saving with both wet and dry air. We introduced this predictive control system to a large-scale data center and had verified the improvement in the energy-saving performance for few month. The air temperature and humidity after one hour could be successfully estimated with an accuracy of correlation coefficient of 0.97 or more using the proposed JIT modeling. Furthermore, we demonstrated that the power consumption of the DC room was significantly reduced by 28.9% using the proposed control algorithm compared to that of the conventional control algorithm.

A novel hypervalent iodine induced nucleophilic substitution of para-substituted phenol ethers in the presence of a variety of nucleophiles is described. UV and ESR spectroscopic studies indicate that this reaction proceeds via cation radicals, 〔ArH^+〕, as reactive intermediates generated by single-electron transfer (SET) from a charge-transfer(CT) complex of phenol ethers with phenyliodine(III) bis(trifluoroacetate) (PIFA). This is the first case that involves a radical intermediate on hypervalent iodine oxidations of aromatic compounds.
