Traffic jam often occurs around the signalized intersection because each takes “stop-and-go cost” to pass through the intersection. Stop-and-go cost traffic increases air pollution and gas consumption, produces greater wear and tear on vehicles, and costs people and businesses money in the delay it imposes. Hence, traffic signal control has significant meanings in reducing the traffic jams efficiently. A modification method of traffic signal control management based on self-organizing is introduced. The self-organizing observed in non-linier coupled oscillators is referred to as “synchronization”, where oscillators having difference natural frequencies are phase locked with some phase delay as result of their mutual or one-side intersection. Simulation illustrate that the new approach is technically sound, moreover it can be implemented in real situation even in non-structure intersection like in Indonesia.

We have simulated the electronic states and the piezoresistive effect response to mechanical strain in single-crystal silicon nanowires (SiNWs) with hydrogen termination by using first-principles calculations of model structures with various wire orientations. Based on our original idea for a small amount of carrier occupation, the carrier conductivity along the wire axis has been calculated in terms of band carrier densities and their corresponding effective masses derived from the one-dimensional first-principles band diagram. In the hydrogen-terminated <001> SiNW model, the uniaxial tensile stress to the longitudinal direction causes a sharp drop in the band energy of the highest valence-band (VB) subband, leading to the redistribution of holes to other VB subbands with a huge hole effective mass. The sudden change in the hole occupation with the increase in effective mass will bring a drastic decrease in the hole conductivity. We have obtained a giant longitudinal piezoresistance coefficient for the p-doped <001> SiNW model, and it is expected that p-doped <001> SiNW without dangling bonds will be one of the most suitable candidates for NEMS piezoresistors due to its giant piezoresistivity. On the contrary, the hole conductivity for the p-doped <111> SiNW depends only on the hole mobility of the highest VB subband. As a result, the longitudinal and transverse piezoresistance coefficients for p-type <111> SiNW without dangling bonds are very small.

It has been established that a long DNA molecule (> 20–30 kilo base-pairs) exhibits a conformational transition from a coiled state to a highly folded state under the presence of condensing agents such as polyamines. We have investigated these changes in conformation of long DNA molecules at a single-molecule level by directly observing conformation of individual DNA molecules in the bulk aqueous solution under fluorescence microscopy. In a cell, DNA is placed in a micrometer-scale space surrounded by phospholipid membrane. In this study, to get insights into the structural characteristics of the genome-size DNA under such a cellular environmental condition, we encapsulated giant DNA (bacteriophage T4 DNA, 166 kilo base-pairs) labeled with fluorescent dyes in a cell-sized (20–60 μm) microsphere coated with phospholipid membrane, and investigated the conformational characteristics and distribution of the DNA in the microsphere under fluorescence microscopy. In the microsphere, T4 DNAs were diffusely distributed within the aqueous phase and exhibited a coiled conformation, when the microsphere was composed of eggPC (phosphatidylcholine from egg yolk). On the other hand, in the microsphere composed of DOPE (1,2-Dioleoyl-sn-glycero-3-phosphoethanolamine), the DNAs were located on the membrane surface in the presence of high concentrations of Mg2+. Single-molecule observation of the DNAs with high-magnification images showed that the DNA exhibited an extended coil conformation and underwent the intra-molecular chain motion on the membrane surface. Under the same experimental condition, a short linear DNA (6 kilo base-pairs) was not bound to the DOPE membrane surface and was present in the aqueous phase in the microsphere, which suggests that the adsorption to the DOPE membrane surface in the presence of Mg2+ is a distinctive characteristic of long DNAs. These results are interpreted in terms of the structural characteristic and its roles of DNA in the cellular environment.

We performed in-situ single cell (W303) manipulation with force measurement inside the Environment-SEM. The mechanical end effector was fabricated from a commercial AFM cantilever by FIB etching. The end effector was assembled to the nanorobotic manipulation system which can realize controlling the position at the nanometer scale. The releasing, sliding and rolling of single cell on a substrate were achieved by controlling the humidity condition inside E-SEM. The influence of humidity to the single cell manipulation inside E-SEM was also discussed for the first time. To our knowledge, it is the first time to manipulate single cell with sliding and rolling movements inside E-SEM.

A micrometer-sized giant vesicle is studied by extending from the inside by using dual-beam optical tweezers in order to measure mechanical properties such as bending rigidity and surface tension of the membrane. As a micrometer-sized vesicle is extended, its shape gradually changes from a sphere to a lemon-shape, and discretely the lemon-shape deforms into a shape of a tube beside a sphere or a lemon part. The surface tension and the bending rigidity of the lipid membrane are obtained from the measured force-extension curve. In the one-phase vesicle, it is found that the surface tension is increasing as the charged component increasing, but the bending rigidity remains almost constant. In the phase-separated vesicle, the characteristic deformation different from one in the one-phase vesicle has been observed.

Increasing dependencies on welfare robot to take care human for welfare and rehabilitation purpose have given the need for robot that have humanlike movement characteristic. Our research is to find out how robot can cooperate with human with humanlike qualities. We start with studying human-human cooperative motion. In this experiment two human subjects move experiment object cooperatively in horizontal left and right direction while looking at the animated experiment object on pc monitor. A visual marker will indicate the final stopping position. We varied the position of visual marker and the communication method between the two humans in order to find out the best communication characteristic of human-human that will be applied to our robot.

We confined actin and giant DNA mixture in a phospholipid coated micrometer scale (cell size) closed space (PMS) as a cell nuclear model system. We report the appearance of a spatially segregated state in PMSs between actin filaments and giant DNA molecules. When the diameter of a PMS was below 15 μm, DNA molecules are excluded toward the surface by forming an assembly with actin filaments. Furthermore, when the coexisting actin concentration was high enough, the aggregation of actin and DNA were still observed on the surface of a PMS whose diameter was above 15 μm. With a decrease in the actin concentration, actin filaments tend to dissolve within the sphere whereas DNA molecules remain to be excluded onto the surface. When the actin concentration becomes still lower, DNA molecules dissolve within the sphere by avoiding surface attachment. We interpreted these results in terms of the generation of a depletion zone near a surface with actin filaments in a PMS.

High-resolution synchrotron X-ray powder diffraction measurement with multiple-detector system has been performed to investigate the scaling effect in ferroelectric PbxSr1−xTiO3 nanoparticles at ambient temperature with various sizes ranging from 10 to 200 nm and various compositions. The peak profiles of the 200 reflections show a large broadening and asymmetry for all particle sizes with decreasing particle size, implying the formation of gradational lattice structure induced by inhomogeneous strain. On the other hand, asymmetric and wide peak profiles of the 200 reflections become a wide symmetry with decreasing x. The crystal structure of PST at ambient temperature were indexed in a tetragonal system for x > 0.4 and in a cubic one for x ≤0.4. This result indicates that a tetragonal-cubic phase boundary exists around x~ 0.4.

Most biological systems are organized according to complex architectures involving multi-scale hierarchical organizations, non linear interactions, feedback controls, and evolutionary behaviors. To understand the underlying physical, biological, and chemical aspects controlling the organization of living systems, we are developing a multidisciplinary, ‘biomimetic’ approach where: i) well-defined artificial cell systems such as giant liposomes of controlled size and composition are produced and placed under biologically relevant contions (artificial cells in a living world); and ii) living cell systems are investigated under a controlled artificial micro-environment, mainly generated by microfluidic means (living cells in an artificial world).
