We study the space of positively expansive differentiable maps of a compact connected C ∞ Riemannian manifold without boundary. It is proved that （i） the C1-interior of the set of positively expansive differentiable maps coincides with the set of expanding maps, and （ii） Cl-generically, a differentiable map is positively expansive if and only if it is expanding.

A series of shake-table tests was conducted by inserting and replacing 4 different types of dampers,or by removing them in a full-scale 5-story steel frame building. The objective is to validate response-control technologies that are increasingly adopted for major Japanese buildings without being attested to-date by a major earthquake. Test results are briefly described,and good performance of the dampers and frame demonstrated. The concepts of the full-scale building tests and various contributions are discussed. The difficulty associated with full-scale dynamic testing is explained.

In some urban parks in Tokyo,semi-natural habitat patches are maintained as nature reserves for birds,called bird *** censuses and vegetation surveys were conducted in eight urban parks in Tokyo from December 2015 to July 2016 to determine the effectiveness of bird sanctuaries on avian species *** relationship between avian species composition and environmental conditions was analyzed by partial redundancy analysis(partial RDA)using vegetation variables,number of visitors,presence or absence of reserves within the same park,area of wooded parts,and normalized difference vegetation index(NDVI)in the surrounding *** results of the partial RDA are as follows:(1)Area,lower vegetation cover,higher vegetation cover,tree species composition obtained from detrended correspondence analysis(DCA)on vegetation survey data,and NDVI in the surrounding area were considered as covariates and explained 17.4-33.6%of the total variation in bird species composition,(2)The presence or absence of sanctuary significantly explained bird species compositional variation regardless of season,indicating that the sanctuaries were beneficial for urban avoider species not only in the sanctuaries but also in the surrounding wooded area,and(3)Tree coverage within a 100 m range and leaf litter coverage also influenced avian species *** concluded that bird sanctuaries and other nature reserves can be beneficial to bird conservation,even within *** positive effect of sanctuaries could be due to the limited influence of human presence and the developed vegetation within *** reserves may play the role of core habitats within the studied urban parks.

Adenosquamous carcinoma is rare,accounting for 3%-4% of all pancreatic carcinoma cases. These tumors are characterized by the presence of variable proportions of mucin-producing glandular elements and squamous components,the latter of which should account for at least 30% of the tumor tissue. Recently,several reports have described cases of adenosquamous carcinoma of the pancreas. However,as the number of patients who undergo resection at a single institute is limited,large studies describing the clinicopathological features,therapeutic management,and surgical outcome for adenosquamous carcinoma of the pancreas are lacking. We performed a literature review of English articles retrieved from Medline using the keywords 'pancreas' and 'adenosquamous carcinoma'. Additional articles were obtained from references within the papers identif ied by the Medline search. Our subsequent review of the literature revealed that optimal adjuvant chemotherapy and/or radiotherapy regimens for adenosquamous carcinoma of the pancreas have not been established,and that curative surgical resection offers the only chance for long-term survival. Unfortunately,the prognosis of the 39 patients who underwent pancreatic resection for adenosquamous carcinoma was very poor,with a 3-year overall survival rate of 14.0% and a median survival time of 6.8 mo. Since the postoperative prognosis of adenosquamous carcinoma of the pancreas is currently worse than that of pancreatic adenocarcinoma,new adjuvant chemotherapies and/or radiation techniques should be investigated as they may prove indispensible to the improvement of surgical outcomes.
