We propose a DBA method with an adaptive DBA cycle for TDM-PON based MFH and campus LANs. Experiments show that the method achieves minimum latency of 60 μ8 and high bandwidth efficiency, depending on traffic.
This paper reports a light controllable single cell driven micro rotary vane pump for transport fluid in small space based on a new type of bio-actuator: Euglena. Different from other types of bio-actuators, Euglena has features of both animals and plants, which will allow, for the first time, bio-actuator functioned in fresh and salt water and take nourishment through photosynthesis. To demonstrate...
This paper proposes a compressive sensing method for the phased array weather radar (PAWR), which is capable of three-dimensional observation with high spatial resolution in 30 seconds. Because of the large amount of observation data, which is more than 1 gigabyte per minute, data compression is an essential technology to operate PAWR in the real world. Even though many conventional studies applied...
This study developed agarose micro casts for the analysis of patterned differentiation of mesenchymal stem cells (hMSCs). The patterned differentiation of hMSCs was observed in agarose micro cast wall. The stained image of hMSCs was automatically analyzed.
Leukemia is a malignant proliferation of hematopoietic cells, characterized by replacement of bone marrow by neoplastic cells. The leukemic cells usually are present in peripheral blood, and may infiltrate reticuloendothelial system, such as liver, spleen, lymph nodes, and other organs such as kidney, testes, bowel, lung, and central nervous system. In general, even in the state of remission, leukemic...
Thoracic complications and changes are frequent in patients with hematological malignancies. In those patients with advanced hematological malignancies pulmonary complications, mostly related to chemotherapy, can be a leading cause of death. Tenholder and Hooper found that 98% of leukemic patients showed pulmonary complications at autopsy (TENHOLDER and HOOPER 1980). Of note however, in recent years...
In this paper, we discuss guidelines for a reward design problem that defines when and what amount of reward should be given to the agents, within the context of reinforcement learning approach. We take keepaway soccer as a standard task of multiagent domain which requires skilled teamwork. The difficulties of designing reward for good teamwork are due to its features as follows: i) since it is a...
Modelling and predicting the potential habitat and future range expansion of invasive species can help managers to mitigate the impact of such species. Because habitat suitability and the colonization process are key determinants of range expansion, inferences drawn from invasion patterns should be based on both attributes. To predict the potential habitat and expansion rate of the invasive tree Bischofia javanica...
Bischofia javanica is the most invasive alien tree species on the Ogasawara Islands; it is seen as a significant problem for biodiversity conservation. B. javanica has colonized four Ogasawara islands, namely, Ototojima, Chichijima, Hahajima and Hirashima. On Ototojima, B. javanica was never abundant and has been almost eliminated through actions of an eradication project operating since...
This study proposes a cell manipulation method with aggregated air bubbles on cell culture medium. This method requires no additional regents nor devices, except for normal cell-culture materials such as cell culture dishes and pipettes. Bubbles generated by pipetting were spontaneously aggregated with regularity on the whole surface and used as a mask for avoiding cell adhesion after cell-seeding...
Our proposed architecture of dynamically reconfigurable hardware for protocol processing (DRHPP) provides flexibility with high area efficiency. It can be used for a communications system-on-a-chip (SoC) in access networks. The DRHPP enables the modification and addition of various functions for protocol processing. Our architecture consists of three types of cells. The optimized number of these types...
This study assessed the wettability of cellular surface with noncontact meniscus manipulation under a microscope. The surface of culture medium covered on cells was manipulated by air-jet and the meniscus of culture medium was generated. The movement of meniscus was monitored with a microscope. The shape of interface between culture medium and air on the cells was different from the part of cells.
A social robot, which is used in a human living environment, is gathering a massive attract from not only robot researchers but also the general people. Because the users of a social robot normally differ from the specialist of robotics, the robot is required to be controlled by an intuitive user-interface. An eye-gaze point is a good signal representing human-intention with interest as compared with...
This study fabricated patterned cell culture system with a self-assembled bubble-raft created on a general cell-culture medium. The bubble raft was composed of bubbles generated by bubbling. After cells were seeded on the bubble raft, the cells were trapped in a gap between adjacent bubbles. The pattern of adherent cells were obtained within 2 h after the cell seeding.
This study proposed a method for the fine alignment of polydimethylsiloxane (PDMS) stamp used in multiple microcontact printing. The procedure of alignment method was organized into three steps; (1) the fabrication of PDMS stamp with an alignment marker, (2) the position detection of PDMS stamp with a noncontact laser displacement sensor on an automated planar x−y axes stage, and (3) the position...
We propose a mobile-DBA with low-latency for a TDM-PON based mobile fronthaul. It utilizes mobile-scheduling information and reduces the latency to about 1/20 of conventional one. Measured latencies (< 50 µs) are enough for LTE.
PIPAAm grafted polystyrene (PIPAAm-Pst) dishes were prepared using visible light irradiation and polystyrene dishes modified with thioxanethone-based photoinitiator. At optimized preparation conditions, PIPAAm-PSs fabricating cell sheets were successfully prepared by 5 mins visible light irradiation. After PIPAAm polymerization, micro-patterned temperature responsive polystyrene culture surface (MPTRCS)...
This study performed multiple micro-contact printing of extra-cellular matrix with a fine alignment system for the position and the posture of polydimethylsiloxane (PDMS) stamp. The position and the posture were adjusted with a 4-axis automated stage with a resolution of 1 μm or 0.0025 deg. The adjustment was achived by monitoring the surface shape of PDMS stamp measured by using a laser displacement...
Micro contact printing is a quite useful technique for patterning protein such as cellular adhesion molecular. Especially, the method is popular to fabricate substrates for cell patterning in tissue engineering. However, a manual printing is difficult, because the stamp made from polydimethylsiloxane (PDMS) is easily deformed, and a printed pattern is also crushed. This study focused on the stiffness...
This paper presents a new search scheme that reduces the energy dissipation of a lookup engine by reducing the number of rules to compare. The lookup engine with the proposed scheme fabricated in 40-nm CMOS reduces the energy dissipation by 96.5% including only 0.5% overhead.
