Leveraging Vision-Based Structure-from-Motion for Robust Integrated Land Vehicle Positioning Systems in Challenging GNSS Environments (2018)

The global navigation satellite system (GNSS) is often considered as the solution of choice for navigating in outdoor environments. However, in the specific care of urban environments, the information delivered by a GNSS receiver is not very precise and may even be unavailable. For this reason, in most cases, the positioning task is realized by coupling of a satellite geo-referencing system with sensors such as odometers, inertial units, etc. To reduce the cost of such navigation solution for land vehicles, the three-dimensional reduced inertial sensor system (3D-RISS) algorithm has been developed for integration with GNSS to provide integrated navigation solution for land vehicles. The inertial sensors are accurate in the short term but drift over time. A solution is then to use other exteroceptive sensors such as cameras and Light Detection and Ranging (LiDAR). The estimation of camera’s egomotion over time is known as visual odometry (VO). Although pose estimation can be achieved by evaluating the best estimate for the essential matrix using Nistér’s 5-point algorithm, iterative estimation from feature correspondences always causes errors that will accumulate over time and lead to drifts that even robust pose-graph optimization algorithms cannot avoid. To remedy this problem, an optimization process such as bundle adjustment is generally applied to optimize the estimation of camera poses and 3D-landmark parameters simultaneously. To make use of this optimization method, we employ structure-from-motion (SfM) techniques by exploiting the projective geometry between 3D-landmarks and their respective projections into 2D imagery. The integration of structure-from-motion algorithms for a single camera with other positioning sensors have been rarely studied, therefore the ultimate goal of this paper is to develop and present results for an integrated SfM/3D-RISS/GNSS system. The resulting solution exhibits improved positioning accuracy over the conventional 2D-2D motion estimation method under certain conditions. Experimental verification of the proposed solution is illustrated through two real road trajectories that were performed on two different land vehicles. A description is provided to show the performance of such integration in details during GNSS outages that last up to 10 minutes.
(Battery Division Research Award) Advanced Energy Storage Systems for Enabling Electrification of Vehicles “Lithium Ion & Beyond” (2019)

To meet the high-energy requirement that can enable the 40-miles electric drive Plug in Hybrid Electric Vehicle (P-HEVs), long range electric vehicle (EV) and smart grid, it is necessary to develop very high energy and high power cathodes and anodes that when combined in a battery system must offer 5,000 charge-depleting cycles, 15years calendar life as well as excellent abuse tolerance. These challenging requirements make it difficult for conventional battery systems to be adopted in P-HEVs and EVs. In this talk, we will present a next generation lithium ion battery that include Ni rich full gradient cathode, a high voltage and nonflammable electrolyte and Silicon-graphene composite anode including a novel pre-lithiation technology to overcome the irreversible loss of this anode in the first cycle. We will then show how Se doping of Sulfur (S) can overcome the conductivity issue of S and eliminate the dissolution of poly-sulfide using an advanced electrolyte system. We will also show that by incorporating Li 2 S in graphene cages, we increase the electrode loading significantly to over 10mg.cm -2 and eliminate the issue of cathode swelling and the use of Lithium metal that impact performance.

Analysis of Finger PIP Implants (2003)

Total joint arthroplasty (TJA) is implemented primarily for the relief of pain, and secondarily for achieving better function by increasing the joint’s strength and motion. In order to keep health costs low, it is desirable that the TJA achieves and maintains a long-term and secure fixation of the implanted components. Unfortunately, clinical follow-up shows that the prosthetic finger implant components have long-term complications including bone resorption, wear, loosening, and failure of the implant components. Although the mechanism of complications is not fully understood, it is well known that the wear and failure of prostheses are highly related to the mechanical forces or stresses of implant components. It is therefore desirable that reliable 3-D computational finite element analysis (FEA) models can be developed and used for the stress analysis of implants. In this study, the finger proximal interphalangeal (PIP) prosthetic components were analyzed using a nonlinear finite element method. Implant components under different joint flexion angles as well as different forces were studied. The stress distribution on the contact surface of the implant component was obtained. The developed FEA models can be used to examine the contact situations (contact stress, contact region, and stress distribution), which are critical to the wear and potential failure of the implant components. Based on FEA results, the design of the current finger PIP implants can be improved for optimum performance and a long-term fixation.

Expression in Escherichia coli and function of Pseudomonas aeruginosa outer membrane porin protein F (1986)

The gene encoding porin protein F of Pseudomonas aeruginosa was cloned onto a cosmid vector into Escherichia coli. Protein F was expressed as the predominant outer membrane protein in a porin-deficient E. coli background and was clearly visible on one-dimensional sodium dodecyl sulfate-polyacrylamide gels in a porin-sufficient background. The identity of the protein F from the E. coli clone and native P. aeruginosa protein F was demonstrated by their identical mobilities on sodium dodecyl sulfate-polyacrylamide gel electrophoretograms, 2-mercaptoethanol modifiabilities, and reactivities with monoclonal antibodies specific of two separate epitopes of protein F. In the course of gene subcloning, a 2-kilobase DNA fragment was isolated, with an apparent truncation of the part of the gene encoding the carboxy terminus of protein F. This subclone produced a 24,000-molecular-weight, outer membrane-associated, truncated protein F derivative which was not 2-mercaptoethanol modifiable and which reacted with only one of the two classes of protein F-specific monoclonal antibodies. The 2-kilobase fragment was used in Southern blot hybridizations to construct a restriction map of the cloned and subcloned fragments and to demonstrate with restriction digests of whole P. aeruginosa DNA that only one copy of the protein F gene was present in the P. aeruginosa chromosome. The protein F produced by the original cosmid clone in a porin-deficient E. coli background was purified. To demonstrate retention of porin function after cloning, the protein F from the E. coli clone was incorporated into black lipid bilayer membranes. Two major classes of channels were revealed. The predominant class of channels had an average conductance of 0.36 nS in 1 M KCl, whereas larger channels (4 to 7 nS) were seen at a lower frequency. Similar channel sizes were observed for porin protein F purified by the same method from P. aeruginosa outer membranes.

Anti-Platelet and Membrane-Rigidifying Flavonoids in Brownish Scale of Onion (2003)

The bio-activity of the brownish scale of onion (Allium cepa) was studied together with identifying the active components and addressing the mode of action. A crude MeOH extract (0.5-1.0 mg/ml) showed the inhibitory effects on human platelet aggregation induced by collagen, adenosine 5′-diphosphate (ADP), thrombin and epinephrine. The anti-platelet extract (1.0 μg/ml) rigidified liposomal membranes by acting on the hydrocarbon core more intensively than the surface of membrane lipid bilayers. Serial solvent extractions and chromatographic purifications provided four isolates which were structurally identified as different quercetin dimers (1 and 2), quercetin (3) and quercetin-4′-glucoside (4). The flavonoidal components 1, 3, 2 and 4 (0.5-2 mM) inhibited collagen-induced platelet aggregation in increasing order of intensity. More active 1 and 3 (2 mM) also dissociated the aggregates produced by ADP. The anti-platelet flavonoids (0.25-10 μM) acted on liposomes of the lipid composition resembling human platelets to cause membrane rigidification which was greatest in the order of 1, 2, 3 and 4. The interaction with membrane lipids to modify membrane fluidity appears to be partly responsible for the anti-aggregatory and disaggregatory effects on human platelets. Although the inedible scale of onion is usually regarded as waste, it has the possibility to be a medicinal resource.

DateLens is a novel calendar interface for PDAs. It supports users in performing planning and analysis tasks by using a fisheye representation of dates coupled with compact overviews, user control over the visible time period, and integrated search. This enables users to see overviews and to easily navigate the calendar structure, and to discover patterns and outliers.
Spectroscopic Analysis on Elementary Reactions of Oxidative Polymerization of 2, 6-Xylenol Catalyzed by Copper Complex (1974)

銅-ピリジン錯体を触媒とする2, 6-キシレノールの酸化重合は,基質の配位(k1),基質から銅(II)への電子移動(ke),活性化された基質の脱離(kd),触媒の再酸化(ko)の四つの素過程からなる触媒サイクルを形成している。銅錯体触媒のスペクトル変化をストップドフロー法で追跡することにより各素反応の速度定数を決定し,触媒機梅の詳細を議論した。各速度定数を比較すると,keまたは本実験では測定不可能であったkdが律速過程であると考えられる。また酸素は銅(II)-基質錯体に関与し,ke過程を促進している。各速度定数は溶媒種の影響を受け,配位能をもった二三の溶媒を除き,k1およびkeは溶媒の極性にともなって増大し,逆にkoは溶媒の極性とともに減少した。
Photodynamic therapy plus low-dose cyclophosphamide generates antitumor immunity in a mouse model (2008)

Photodynamic therapy (PDT) is a modality for the treatment of cancer involving excitation of nontoxic photosensitizers with harmless visible light-producing cytotoxic reactive oxygen species. PDT causes apoptosis and necrosis of tumor cells, destruction of the tumor blood supply, and activation of the immune system. The objective of this study was to compare in an animal model of metastatic cancer PDT alone and PDT combined with low-dose cyclophosphamide (CY) a treatment that has been proposed to deplete regulatory T cells (T-regs) and increase the immune response to some tumors. We used J774 tumors (a highly metastatic reticulum cell sarcoma line) and PDT with benzoporphyrin derivative monoacid ring A, verteporfin for injection (BPD; 1-mg/kg injected i.v. followed after 15 min by 150 J/cm(2) of 690-nm light). CY (50 or 150 mg/kg i.p.) was injected 48 h before light delivery. PDT alone led to tumor regressions and a survival advantage but no permanent cures were obtained. BPD-PDT in combination with low-dose CY (but not high-dose CY) led to 70% permanent cures. Low-dose CY alone gave no permanent cures but did provide a survival advantage and was shown to reduce CD4+FoxP3+ T-regs in lymph nodes, whereas high-dose CY reduced other lymphocyte classes as well. Cured animals were rechallenged with J774 cells, and the tumors were rejected in 71% of mice. Cured mice had tumor-specific T cells in spleens as determined by a (51)Cr release assay. We conclude that low-dose CY depletes T-regs and potentiates BPD-PDT, leading to tumor cures and memory immunity.
Association of SUMO4, as a Candidate Gene for IDDM5, with Susceptibility to Type 1 Diabetes in Asian Populations (2006)

Recent study demonstrated that M55V variant in SUMO4 at IDDM5 was associated with susceptibility to type 1 diabetes. Subsequent studies, however, showed inconsistency in the association. To clarify the population-wide effect on the association of SUMO4 with type 1 diabetes, we have performed meta-analysis including our own data in Asian populations, which confirmed a highly significant association in Asian populations (summary odds ratio [OR]: 1.29, P = 7.0 x 10(-6)), but indicated significant heterogeneity in the genetic effect of the SUMO4 gene on type 1 diabetes among diverse ethnic groups. These observations indicated the association of SUMO4 with type 1 diabetes in Asian populations.

Reverse Prosthesis for Proximal Humerus Fracture, Technique and Results (2008)

The reverse prosthesis has become a treatment of choice for glenohumeral osteoarthritis in a cuff-deficient shoulder. It allows restoration of mobility despite the loss of rotator cuff function. Hemiarthroplasty, the historical standard of care for proximal humeral fractures requiring replacement, fails most commonly because of tuberosity nonunion. Therefore, in the face of poor bone quality, the reverse prosthesis is a logical choice for acute fractures to improve postoperative mobility in elevation regardless of tuberosity healing. Nevertheless, the healing of the tuberosities may influence the recovery in active external rotation. The purpose of this article is to report on the superolateral technique to implant a reverse shoulder prosthesis for acute proximal humeral fractures, emphasizing the technique of tuberosity fixation, and to analyze previously published series. Considering the follow-up and complication risks, the reverse prosthesis should be reserved for fractures involving elderly patients. The decision to use a reverse prosthesis for an acute fracture should be based on a thoughtful risk-benefit analysis between hemiarthroplasty and reverse shoulder arthroplasty.
Multimodal Enzyme‐Carrying Suprastructures for Rapid and Sensitive Biocatalytic Cascade Reactions (2021)

Colloidal assemblies of mesoporous suprastructures provide effective catalysis in an advantageous volume-confined environment. However, typical fabrication methods of colloidal suprastructures are carried out under toxic or harmful conditions for unstable biomolecules, such as, biocatalytic enzymes. For this reason, biocatalytic enzymes have rarely been used with suprastructures, even though biocatalytic cascade reactions in confined environments are more efficient than in open conditions. Here, multimodal enzyme- and photocatalyst-carrying superstructures with efficient cascade reactions for colorimetric glucose detection are demonstrated. The suprastructures consisting of various functional nanoparticles, including enzyme-carrying nanoparticles, are fabricated by surface-templated evaporation driven suprastructure synthesis on polydimethylsiloxane-grafted surfaces at ambient conditions. For the fabrication of suprastructures, no additional chemicals and reactions are required, which allows maintaining the enzyme activities. The multimodal enzymes (glucose oxidase and peroxidase)-carrying suprastructures exhibit rapid and highly sensitive glucose detection via two enzyme cascade reactions in confined geometry. Moreover, the combination of enzymatic and photocatalytic cascade reactions of glucose oxidase to titanium dioxide nanoparticles is successfully realized for the same assay. These results show promising abilities of multiple colloidal mixtures carrying suprastructures for effective enzymatic reactions and open a new door for advanced biological reactions and enzyme-related works.
Ensuring robust ESD design with comprehensive reliability verification (2022)

Weaknesses in electrostatic discharge (ESD) connection paths directly contribute to field failures if they are not properly identified and fixed pre-silicon. Although traditional verification tools such as design rule checking (DRC), layout vs. schematic (LVS) verification and electrical rule checking (ERC) are still required in an integrated circuit (IC) verification flow, they can no longer be the only tools used. This work demonstrates the importance of adding comprehensive reliability checking to the overall IC verification flow to accurately identify reliability issues that cannot be found using traditional verification methods.
Tunable plasmonics and metasurfaces for applications in optical switching and space technology (Conference Presentation) (2017)

Plasmonic nanoantennas are of interest because of their capability to enhance light-matter interactions. We present new results where antennas are used to obtain nanoscale devices with tunable characteristics. Applications of these devices include electrically controlled antennas, antennas integrated on silicon waveguides, and optical solar reflectors for spacecraft. By using tunable materials such as vanadium dioxide and doped-metal oxides, we demonstrate precise control and active tunability of the optical response. Experimental results are supported by combined electro-optical modelling at the nanoscale.
Suppression of silicide formation in Ta/Si system by ion-beam-assisted deposition (1997)

In order to increase the failure temperature of a Ta diffusion barrier for Cu, the suppression of silicide formation in a Ta/Si system by ion-beam-assisted deposition of Ta film was investigated. When the Ta layer was deposited without ion bombardment, the reaction between Ta and Si started at 600 °C. In the case where the Ta film was prepared with concurrent ion bombardment, however, the silicide formation was retarded up to 700 °C. The suppression of Ta silicide formation can be attributed to a densification of grain boundaries in the Ta film by ion bombardment, followed by a reduction of the chemical driving force for the initial stage of silicide formation. The Ta diffusion barrier deposited by ion-beam-assisted deposition effectively suppressed the reaction between Si and Cu layers up to 650 °C for 30 min.
Probabilistic clock synchronization in large distributed systems (1994)

Clock synchronization within a distributed system is a problem that has been studied extensively in recent years. Of the many solutions proposed thus far, probabilistic synchronization algorithms provide arguably the best compromise between tightness of synchronization and overhead imposed on the system. The main drawbacks of probabilistic algorithms are the requirement of a master/slave organization of clocks, and the relatively high number of synchronization messages that must be sent. These two drawbacks can make them unsuitable for use in large distributed systems. In this paper, we propose a synchronization algorithm that does not use master/slave clocks and reduces the number of synchronization messages needed. The nodes of the system are divided into a number of overlapping groups. Within a group, each node uses one of two probabilistic techniques to estimate the values of other clocks in the group, and uses an interactive convergence algorithm on the resulting estimates to adjust its local clock. Groups are selected so that the maximum skew between any two group members is bounded.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
