WABIAN robot from Japan steps closer to human walk

first_img More information: … top/research/wabian/via IEEE Spectrum © 2013 Explore further Their work on WABIAN has been in step with the Japan government’s concern about technology for an aging population, to preserve a decent quality of life for the aging, despite limitations on freely moving about that may result from old age. The team stated in the past that a robot as “a human’s partner” would provide daily robotic assistance, and that kind of application was more in their line of view than an industrial robot earmarked for highly specified and constrained applications. To accomplish the task, robots have to be able to move in indoor and outdoor conditions, they said, and biped humanoid robots are best suited for this. They also noted that aside from robots as human assistants, there was a need for evaluation methods for assistive equipment, dependent on human body measurements. A biped humanoid robot optimized to serve as a human motion simulator is a step in the right direction. This document is subject to copyright.

In their latest workup of the WABIAN robot, now called WABIAN-2RIII.the researchers redesigned lower legs, after studying humans walking. They analyzed the average size and movement range in humans, and analyzed motion-capture data to decide on the best performance requirements.The researchers, T. Otani, A. Iizuka, D. Takamoto, H. Motohashi, T. Kishi, P. Kryczka, N. Endo, L. Jamone, K. Hashimoto, T. Takashima, H.O. Lim, and A. Takanishi, discuss their work in the paper presented at ICRA. The paper is titled, “New Shank Mechanism for Humanoid Robot Mimicking Human-like Walking in Horizontal and Frontal Plane.” According to IEEE Spectrum, they had the following results: In tests of walking in place, (1) they were able to match the human step time of 0.6 seconds; (2) they matched the required 12-degree foot rotation and 90-mm step width; (3) they successfully reduced its center of mass lateral movement from 50 mm down to 34 mm. The researchers only conducted standing tests, with walking in place, and switching balance from foot to foot. In the future, the researchers intend to work on the robot’s forward walking. Robots learn to take a proper handoff by following digitized human examples Citation: WABIAN robot from Japan steps closer to human walk (2013, June 2) retrieved 18 August 2019 from ( —Researchers designing adult bipedal robots have faced a challenge in limitations in a robot’s walking pattern. They seek ways to improve on designs to have robots move more naturally. Improving the walking function has been the goal of researchers at the Humanoid Robotics Institute at Waseda University in Japan. Last month, led by Professor Atsuo Takanishi, the team presented the results of their efforts at the IEEE International Conference on Robotics and Automation (ICRA) in Germany. What they achieved more closely replicates normal human foot movements than before. The Institute’s researchers turned to their humanoid robot, WABIAN-2R (WAseda BIpedal humANoid – No. 2 Refined), which already had a flexible pelvis, and stretched knees. WABIAN-2R’s feet also had the distinction of a curving arch and flexible toes, landing heel-first and lifting off at its toes, noted the IEEE Spectrum report. The robot is under 5 feet tall (148 cm), and weighs 64 kg (141 pounds), with 41 degrees of freedom.last_img read more

Researchers discover UGC 3672 galaxy to be an unusual merging triplet of

first_img Hubble uncovers a galaxy pair coming in from the wilderness Citation: Researchers discover UGC 3672 galaxy to be an unusual merging triplet of gas-rich dwarf galaxies (2016, November 8) retrieved 18 August 2019 from UGC 3672 is located near the center of the nearby Lynx-Cancer intergalactic void. This void, which is about 59 million light years away from Earth, was recently a subject of detailed surveys due to its relative proximity. Lynx-Cancer gives scientists the opportunity to study galaxies to a much fainter mass and luminosity limit than have been done in more distant voids.In September 2015, a team of researchers, led by Jayaram Chengalur of the National Center for Radio Astrophysic in Pune, India, conducted observations of UGC 3672 lasting approximately five hours. They used the Giant Metrewave Radio Telescope (GMRT) located near Pune to carry out hydrogen line (H I line) observations of UCG 3672 and also analyzed the optical photometry data available in the the Sloan Digital Sky Survey (SDSS) in order to study this peculiar galaxy in detail.The data investigated by the team allowed them to draw conclusions that UGC 3672 is, indeed, a triplet of gas-rich dwarf galaxies.”We find that UGC 3672 consists of an approximately linearly aligned triplet of gas rich dwarfs with large scale velocity continuity along the triplet axis,” the scientists wrote in the paper.According to the research, the faintest component of the triplet, designated UGC 3672A, is extremely gas-rich and also extremely metal deficient. UGC 3672B and UGC 3672C are significantly less gas-rich, four and six times less gas-rich respectively. It is also noteworthy that star formation is much more wide spread in ‘B’ and ‘C’ rather than in the ‘A’ dwarf.Based on the observations, the astronomers assume that the location of the UGC 3672 system in an extremely low-density environment is not coincidental, but is rather a consequence of structure formation proceeding more slowly.”We suggest that the location of this highly unusual system is not a coincidence but is related to the ‘cosmic microscope and time machine’ effects associated with voids,” the paper reads.Intergalactic voids are regarded by astronomers as such “cosmic microscopes and time machines” as they offer an opportunity to look at both the earlier stages of structure formation. Furthermore, voids allow probing smaller scales of the power spectrum than is probed by structures in dense regions.The study also confirms that the so-called “wet” mergers (mergers between gas-rich galaxies) could produce gas-rich disks. The authors note that in the case of UGC 3672, the linear arrangement and velocity continuity of the galaxies in this system, along with the fact that the diffuse gas appears to be settling into a rotating disk, indicate that a wet merger with flow along filaments is a possible pathway for the formation of gas-rich disks.”Our observations indicate that wet mergers of galaxies flowing along a filament is a possible pathway for the production of disk like systems,” the researchers wrote.

Explore further (—Astronomers from India and Russia revealed new information about the composition of the galaxy UGC 3672. According to a paper published Nov. 4 on the arXiv pre-print server, UGC 3672 is actually a triplet of very gas-rich dwarf galaxies in the process of merging. More information: UGC 3672: An unusual merging triplet of gas-rich galaxies in the Lynx-Cancer void, arXiv:1611.01271 [astro-ph.GA] present HI 21cm and optical observations of UGC 3672 which is located near the centre of the nearby Lynx-Cancer void. We find that UGC 3672 consists of an approximately linearly aligned triplet of gas rich dwarfs with large scale velocity continuity along the triplet axis. The faintest component of the triplet is extremely gas-rich (MHI/LB ~ 17) and also extremely metal deficient (12+log(O/H) ~ 7.0). The metallicity of this dwarf is close to the ‘floor’ observed in star forming galaxies. Low resolution HI images show that the galaxy triplet is located inside a common HI envelope, with fairly regular, disk like kinematics. At high angular resolution however, the gas is found to be confined to several filamentary tidal tails and bridges. The linear alignment of the galaxies, along with the velocity continuity that we observe, is consistent with the galaxies lying along a filament. We argue that the location of this highly unusual system in an extremely low density environment is not a coincidence, but is a consequence of structure formation proceeding more slowly and also probing smaller scales than in regions with average density. Our observations also indicate that wet mergers of galaxies flowing along filaments is a possible pathway for the formation of gas rich disks. The UGC 3672 system provides an interesting opportunity to study the kind of interactions typical between high redshift extremely gas rich unevolved small systems that lie at base of the hierarchical galaxy formation model. © 2016 This document is subject to copyright.

New species of ancient bird discovered in New Mexico

Early Paleocene landbird supports rapid phylogenetic and morphological diversification of crown birds after the K–Pg mass extinction, Proceedings of the National Academy of Sciences (2017). DOI: 10.1073/pnas.1700188114AbstractEvidence is accumulating for a rapid diversification of birds following the K–Pg extinction. Recent molecular divergence dating studies suggest that birds radiated explosively during the first few million years of the Paleocene; however, fossils from this interval remain poorly represented, hindering our understanding of morphological and ecological specialization in early neoavian birds. Here we report a small fossil bird from the Nacimiento Formation of New Mexico, constrained to 62.221–62.517 Ma. This partial skeleton represents the oldest arboreal crown group bird known. Phylogenetic analyses recovered Tsidiiyazhi abini gen. et sp. nov. as a member of the Sandcoleidae, an extinct basal clade of stem mousebirds (Coliiformes). The discovery of Tsidiiyazhi pushes the minimum divergence ages of as many as nine additional major neoavian lineages into the earliest Paleocene, compressing the duration of the proposed explosive post–K–Pg radiation of modern birds into a very narrow temporal window parallel to that suggested for placental mammals. Simultaneously, Tsidiiyazhi provides evidence for the rapid morphological (and likely ecological) diversification of crown birds. Features of the foot indicate semizygodactyly (the ability to facultatively reverse the fourth pedal digit), and the arcuate arrangement of the pedal trochleae bears a striking resemblance to the conformation in owls (Strigiformes). Inclusion of fossil taxa and branch length estimates impacts ancestral state reconstructions, revealing support for the independent evolution of semizygodactyly in Coliiformes, Leptosomiformes, and Strigiformes, none of which is closely related to extant clades exhibiting full zygodactyly.

Credit: Thomas Stidham Citation: New species of ancient bird discovered in New Mexico (2017, July 11) retrieved 18 August 2019 from Explore further Approximately 65 million years ago, planetary scientists believe, a large asteroid struck the Earth near what is now the Yucatan Peninsula. The impact and its aftermath were so massive that it caused the extinction of approximately 70 percent of plants and animals on the planet. Scientists have been able to piece together what happened to many land animals in the millions of years after the great extinction, but little progress has been made regarding birds. Because their bones are smaller and more fragile, birds do not fossilize as well as other animals. Thus, they leave behind fewer traces of their existence. That is why the new find is so important—because it is helping to fill in the phylogenetic tree.The discovery of the fossil (which the team has named Tsidiiyazhi abini) was actually made by Ryan and Taylor Williamson, 11-year-old twin sons of co-author Thomas Williamson, as the family was out on a fossil hunting expedition. The father and his colleagues returned to the site to unearth the fossil remains and then to study them. They were not in good shape, the team reports, but there was enough material to get a feel for what the bird looked like. The team was also able to date the fossil and to compare it with the few other fossils that have been found in other locations from roughly the same time period. That allowed the team to flesh out the family tree to include as many as 10 major bird groups existing as early as four million years after the great extinction—much earlier than previously believed. The bird was dated to approximately 62 to 65 million years ago, which, the team notes, suggested birds recovered rapidly from the asteroid strike. They note also that the bird closely resembles the modern mousebird, and had the unique ability to turn its fourth toe. This allowed it to turn its body completely about-face—a feature seen with modern owls. © 2017 Artist’s rendering of Tsidiiyazhi abini. Credit: Sean Murtha.

New evidence suggests the Devonian Nekton Revolution never occurred

center_img Journal information: Proceedings of the Royal Society B More information: The Palaeozoic colonization of the water column and the rise of global nekton, Proceedings of the Royal Society B (2018). rspb.royalsocietypublishing.or … .1098/rspb.2018.0883AbstractThe colonization of the water column is among the most important transformations in the evolution of animal life and global ecosystems. The Devonian nekton revolution has been identified as a major macroevolutionary event signifying the rapid occupation of the water column by independent radiations of swimming animals. Using new data, an expanded taxonomic coverage, sample standardization and increased ecological resolution, we analysed patterns of nektonization during the Palaeozoic. We find that nekton and eunekton were well established prior to the Devonian and did not diversify dramatically during any Palaeozoic interval. Relative nektic diversity and occurrences decreased rather than increased during the Devonian. Eunektic diversity and occurrences increased throughout the Palaeozoic, but this rise was protracted and cannot be attributed to any single interval. Our new data indicate that the metazoan colonization of the water column was considerably more complex and gradual than previously understood.

Credit: Light Science & Applications, doi: 10.1038/s41377-018-0062-5. Quantum emitters can be integrated in monolithic nanoscale plasmonic circuitry via low-loss plasmonic configurations to confine light well below the diffraction limit. In integrated quantum plasmonics, waveguides based on surface plasmon polariton (SPP) modes that propagate electromagnetic waves along metal-dielectric or metal-air interfaces are superior to dielectric-based (and therefore diffraction-limited) photonic waveguides. The observation is in respect to the available Purcell enhancement from embedded quantum emitters and the ongoing trend toward on-chip integration and miniaturization to realize optical signal processing and integrated circuits. Different metal-dielectric configurations have been developed for strong light-matter interactions at the scale of the single photon to support the propagation of plasmonic modes confined beyond the diffraction limit. The property can enable unique prospects to design highly integrated photonic-signal processing systems, sensors and optical imaging techniques with nanoscale resolution.

Credit: Light Science & Applications, doi: 10.1038/s41377-018-0062-5. The study was the first to detail the synthesis and characterization of the GeV nanodiamonds. The nanodiamonds were produced using the high-pressure, high-temperature (HPHT) method; Ge was introduced during the growth process to incorporate single GeV centers. The scientists proposed and demonstrated a hybrid approach for nanofabrication using DLSPPW structured on single silver (Ag) crystals that considerably lowered SPP dampening rates, compared to Ag films fabricated by other techniques. The method facilitated sufficiently long SPP propagation at the excitation and emission wavelengths of GeV centers in nanodiamonds incorporated within a plasmonic chip. © 2018 The structure of the synthetic GeV nano and microdiamonds were observed in the raw sample using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Synthetic nanodiamonds were spin coated onto Ag-coated silicon wafers and scanned with confocal fluorescence microscopy. Measured data indicated ultrabright, spectrally narrow and stable single photon sources based on single GeV centers in the nanodiamonds, suitable for highly integrated circuits. The polarization characteristics of the GeV nanodiamonds were measured using an analyzer in the detection pathway to determine the projection of single photons emitted on the surface plane. The data measured for a single GeV nanodiamond fit the model polarization characteristics of diamond color centers based on group-IV elements in the periodic table (e.g. silicon-vacancy SiV, germanium-vacancy GeV, and tin-vacancy SnV).

Citation: On-chip excitation of nanodiamonds embedded in plasmonic waveguides (2018, October 5) retrieved 18 August 2019 from Journal information: Light: Science & Applications Additionally, the authors used a single crystalline Ag flake instead of Ag film to significantly enhance the DLSPPW propagation length. Green laser light transmitting through the DLSPPW mode was optically characterized as polarization along the waveguide axis. Transmission was measured for several waveguides of varying lengths to show extraordinary propagation lengths (~11.8 µm) for the green laser light through the low-loss DLSPPW. Using a similar set-up, the scientists proceeded to demonstrate and confirm remote excitation of the GeV center coupled to the DLSPPW mode. Subsequently, the GeV decay rate was simulated using the finite element modeling (FEM) method and a decay rate of up to four-fold was predicted for a GeV center in the waveguide compared to its emission in vacuum. The system demonstrated superior performance when compared with previously demonstrated systems, the observed Purcell factor can be further enhanced in future studies by using a larger refractive index dielectric such as titanium dioxide (TiO2). The study opens the way to integrate an excitation laser, quantum emitter and plasmonic circuit onto the same chip. Previous strategies have demonstrated the detection of single plasmons and two-plasmon interference on a chip. By combining all three technologies on a single chip, the authors envision that it will be possible to integrate all elements of a quantum plasmonic circuit on a chip in the near future.center_img Schematic illustration of the device layout and working principle for on-chip excitation of a nanodiamond.

A variety of SPP-based structures created in the past include metal nanowires (NW), parallel NWs, V-grooves (VGs) and wedge waveguides that have demonstrated single plasmon guidance for potential quantum applications. The practical realization of such integrated quantum photonics has remained elusive due to several challenges, including high propagation losses of SPP modes and the limited control on single quantum emitters. More recently, studies have nanofabricated low-loss, dielectric-loaded SPP waveguides (DLSPPWs) structured on a silver film for simple quantum plasmonic circuits composed of embedded nanodiamonds with nitrogen-vacancy centers.Now writing in Light Science & Applications, Hamidreza Siampour and co-workers have taken a step forward in the field of integrated quantum plasmonics by demonstrating on-chip coupling between a single photon source and plasmonic waveguide. In the approach, the physicists engineered a nanodiamond featuring a germanium vacancy (GeV) center that emits single photons, embedded inside a plasmonic waveguide composed of dielectric hydrogen silsesquioxane (HSQ) atop a layer of silver fabricated using electron-beam lithography. When a green laser light (532 nm) was coupled to one end of the waveguide via grating couplers to propagate to the nanodiamond, it excited the GeV center, which emitted a single photon that coupled into the plasmon mode of the waveguide. In the work, the researchers achieved long waveguide transmission lengths (33 µm) and efficient coupling (56 percent) to open new avenues in the development of chip-based quantum circuitry.

The observed capacity for single-photon emission in diamond nanocrystals can enable hybrid quantum-plasmonic systems that can facilitate remote excitation of the GeV centers incorporated in a plasmonic chip. Siampour et al. elegantly demonstrated the efficient long-range delivery of the GeV-DLSPPW system compared with other hybrid quantum plasmonic systems. An exceptional figure of merit (FOM) of 180 was revealed in the study due to a ~six-fold Purcell enhancement, 56 percent coupling efficiency and ~33 µm transmission length at a wavelength (λ) of 602 nm. Electron beam lithography was used to fabricate the waveguides with HSQ resist on Ag-coated substrates to contain the nanodiamonds featuring single GeV centers – added via controlled placement into the device. The technology provided ~30 nm precision in placement, enhanced via observations with SEM imaging, limited by the size of nanodiamonds, which could be fabricated down to 1 nm using existing diamond synthetic technology. The fabricated waveguide was visualized with atomic force microscopy (AFM) and with a charge coupled device (CCD) camera after nanodiamond excitation via a green pump laser. , Nature Photonics This document is subject to copyright.

Redefining traditional art

first_imgAmidst all the blitzkrieg of new media art and monumental installations, here is a gallery that believes in reinventing and redefining tradition, Gallerie Ganesha is bringing forth a collection of artworks deeply inspired by lineage as well as traditions of tribal and folk art for the India Art Fair.Commenting on the same Shobha Bhatia, director, Gallerie Ganesha said ‘A strong heritage can influence descendants for generations. Tradition, which is always old, is at the same time ever new because it is always reviving. Being born again in each generation. The work of an artist in any era is essentially an amalgamation of his ancestors and predecessors and his own experiences. This year we are showcasing works with a special focus on what lineage influences each artist and how they have chosen to take that inspiration forward. It is an attempt to get the artists to look within and virtually put a spot light on the vocabulary they are using in order to weave their individualistic tales. At the same time, our focus largely is on folk and the tribal tradition.’ Also Read – ‘Playing Jojo was emotionally exhausting’One can see works by the well known tribal artist, Jangarh Singh Shyam, from Madhya Pradesh who died under tragic circumstances in Japan.  Artists who are inspired by the folk tradition are Neelkant Choudhary from Madhubani, Bihar, Uma Shankar Shah from Nepal, late Professor K.S.Kulkarni, Dipak Banerjee, Jayasri Burman, Ganga Singh, Laxma Goud and Atul Sinha amongst others.Talking about his works Neelkant Choudhary said, ‘The fine lines of my works have been pulled from the deep and long tradition of the Mithila-Madhubani art form and married to modern metaphors under delicate ministering. I have also brought to the form an entirely new idiom of tone and tenor. Also Read – Leslie doing new comedy special with NetflixAs an artist with a traditional background it was very difficult and also very interesting to break away from the former to latter while also trying to work on the traditional lines so as to maintain the familiarity with the traditional paintings.’Uma Shankar Shah has done etchings and unique prints based on Maithili art, the theme of which is mostly from the Ramayana and prayer wheels from Nepal. He has transformed the traditional art of Maithili Painting into a contemporary extravaganza while meticulously using abstract symbols, motifs, brilliant colours and bold lines characteristic of the traditional art form. Dipak Banerjee’s work is marked by a predominance of patterned structures, calligraphy, anthropomorphic images, Yantras and Mandalas. Over the years he has become more and more rooted in a pictorial mode close to the imagination of Indian miniaturists and folk artisans. KS Kulkarni had developed most simplified constructive forms which have a content dwelling in contemporary psyche. Post modern, unadorned and yet somehow in its heartbeats are engraved into our mind from the tantric concepts of life and going back to primitive cavemen and bushmen.Jayasri Burman’s figures have gained iconic proportions where they no longer remain confined within the space of a mythological or a religious framework, rather they have moved beyond those conventions to establish newer grounds for approaching art.Her work is a reflection of history, myth and ancient texts – an element which transcends time and easy classification in a very immediate and emphatic manner. Atul Sinha’s wood sculptures have a very distinct and prominent overtone of tribal art. The simplicity of form merging beautifully with the ‘complexity’ of narrative to create alluring three dimensional art.Apart from the above, artworks by artists like Alok UNiyal, Avijit Dutta, Badri Narayan, Devdatta Padekar, Maite Delteil, Mohan Singh, Murlidhar Rai, Neeraj Goswami, Niti Jain, Paresh Maity, Sakti Burman, Sangeeta Gupta, Satish Gujral, Sidharth, Vinita Karim, Nayanaa Kanodia, Maya Burman and Ganga Singh.When: 30 JanuaryWhere: NSIC Exhibition Groundslast_img read more
