This study aims to examine the following three hypotheses on the impact of global warming on the populations of the water strider, Aquarius paludum in the Kochi-Nankoku area (33。30'N) of Kochi prefecture, Japan through the recent data collected in 2009-2011. 1) Has the generation number increased? 2) Has aestivation appeared in adults? 3) Have overwintering adults stopped dispersing between the water surface and overwintering lands-sites far away from water and, instead, overwintered on/near the shore? Sampling data showed that the number of generations may have increased from three (1989-2002 strains) and four (2004-2008) to five (2009-2011) per year in Kochi (33。N). The ratio of adults having well developed flight muscles decreased from 45% in 1995 to 24% - 28% in 2009-2011 inoverwintering adults collected from the field in fall likely as a result of histolysis. “Mosaic-typed” wing morph group with long fore-wings and short hind-wings newly appeared in 2009-2011 in the Kochi-Nankoku overwintering populations. The mosaic-typed wings group cannot fly and the black and long fore wings might function as absorbing apparatus of sun-lights in the daytime of winter. Some overwintering adults seem to stop migrating between water bodies and overwintering sites on land far from the water bodies and overwinter, instead, near the shore. The use of Aquarius paludum as a biological indicator would be possible in the future, because this species can respond and change their reproductive and dispersal characteristics to the global change.

An Approximate High Gain Observer for Speed-sensorless Estimation of Induction Motors

引用

IEEE/CAA Journal of Automatica Sinica 2019年第1期6卷 53-63页

作者： Yebin Wang Lei Zhou Scott A.Bortoff Akira Satake Shinichi furutani IEEE Mitsubishi Electric Research Laboratories the Department of Mechanical Engineering Massachusetts Institute of Technology the Advanced Technology R&D Center Mitsubishi Electric Corporation

Rotor speed estimation for induction motors is a key problem in speed-sensorless motor drives. This paper performs nonlinear high gain observer design based on the full-order model of the induction motor. Such an effort appears nontrivial due to the fact that the full-model at best admits locally a non-triangular observable form(NTOF), and its analytical representation in the NTOF can not be obtained. This paper proposes an approximate high gain estimation algorithm, which enjoys a constructive design, ease of tuning, and improved speed estimation and tracking performance. Experiments demonstrate the effectiveness of the proposed algorithm.

Dear Editor,MPL is a cytokine receptor that regulates the production of myeloid cells,in particular megakaryocytes and platelets(Kaushansky,2005).Dimerization of MPL is important not only for the initiation of signalling(Kaushansky,2005)but also for the resistance to a recent therapy for myeloproliferative neoplasms(Koppikar et al.,2012).In the current model,cytokine receptors exist as a mixture of monomers and dimers without ligand stimulation,while ligand binding induces additional receptor dimerization(Kaushansky,2005).

The threat of biological and chemical terror acts remains a growing worldwide concern.There is therefore a need to develop appropriate technology for the detection of chemical and biological warfare agents,with early identification intended for use by first responders.Here,we disclose the developed autonomous air sampling and detection system for evaluation of the presence of chemical and biological warfare agents that can be harmful to the population.The current device utilizes the designed mist generator-assisted air collection system(338 l min^(−1))and biosensing chip technologies,such as electrochemical measurement,Au nanoparticle-based localized surface plasmon resonance,and rapid microfluidic chip PCR for detection of minute concentrations lower than the mean lethal dose(LD_(50))of nerve gases(sarin and VX),toxic proteins(BTX/A/Hc and ricin),and pathogens(anthrax simulant).An operation time of only 5–15 min is needed for the collection and detection;sample preparation is already integrated into the system without the need for direct human intervention.In addition to the system’s sensitivity and ease of use,its portability makes it highly beneficial for first responders,which could aid in immediate risk assessment and mitigation of on-site events.

The Protective and Recovery Effects of Fish Oil Supplementation on Cedar Pollen-Induced Allergic Reactions in Mice

引用

Food and Nutrition Sciences 2012年第1期3卷 40-47页

作者： Akiko Hirao Naoki furutani Hiroki Nagahama Misa Itokawa Shigenobu Shibata 不详

Obesity is associated with the production of pro-inflammatory cytokines and therefore can lead to worsening of allergic reactions. Thus, there is cross-talk between obesity and allergic reactions. In this study, we investigated whether the anti-obesity action of fish oil supplementation is involved in the anti-allergic action also induced by fish oil. We observed attenuation of cedar pollen-induced IgE serum increases in two experimental protocols: 15% fish oil supplementation for 8 weeks, which attenuated body weight increases compared with 15% soybean supplementation, and 4% fish oil supplementation for 2 weeks, which did not affect body weight increases compared with 4% soybean or 4% lard supplementation. The former but not the latter protocol attenuated sneezing after pollen challenge. Gene expression of TNF-α and IL-13, a Th2 cytokine, was moderately reduced in the trachea and nasal mucosa in mice fed fish oil supple- ments. In a third protocol, fish oil was administered for up to 15 weeks after a cedar pollen sensitization and challenge-induced increase in IgE levels. These levels decreased following fish oil supplementation but were almost unaffected by soybean oil supplementation. Surprisingly, the IL-13 gene expression level in the nasal mucosa and trachea was higher in the fish oil group than in the soybean oil group. These results suggest that fish oil supplementation before, during, or after antigen sensitization and challenge in mice helped to reduce cedar pollen-induced allergic reactions in- dependent of its anti-obesity action. Fish oil supplementation can also exhibit pro- or anti-inflammatory action against IL-13 expression depending on the experimental protocol.
